What are the refueling principles and storage systems of calcium hydroxide equipment

/in /by

For users, buying calcium hydroxide equipment is to use the equipment. But as long as it is mechanical equipment, it cannot be separated from the use of oil. Calcium hydroxide equipment is also the same. So, what are the principles and systems for calcium hydroxide equipment when adding and replacing oil? Let’s take a look at the refueling principles and storage system of calcium hydroxide equipment.

The principle of refueling calcium hydroxide equipment

1. For calcium hydroxide equipment with oil sight glass, the middle line of the oil sight glass is used as the lower limit line, and the upper limit line is 5 mm above the lower limit line. For those with tubing joints, the above joints are used as the upper limit line, and half of the upper and lower joints are used as the lower limit line.

2. For equipment with tubular oil mark, the upper and lower limit lines on the tubing are used as the principle of refueling; for pumps with oil, the upper limit is located at the joint surface between the base and the needle seat, and the lower limit line is 10 mm lower than the upper limit line. It can be observed according to the plastic pipe on the oil pump.

3. The principle of refueling is about 1/2 of the internal gap and should not be overfilled.

4. The calcium hydroxide equipment should be cleaned before storage, and the water used to remove dirt, dust and other dirt should be cleaned. The lubricated parts should be oiled, and the outer machined surface should be oiled.

5. In addition to refueling, the processed surface should be wrapped and protected. The nameplate on the machine should be wiped clean with clear writing. The water should be completely drained. The lubricated parts should be oiled, and the outer machined surface should be oiled.

6. When the calcium hydroxide equipment and its accessories are out of use, they should be stored in a dry, ventilated, easy-to-drain and easy-to-observe place to avoid disassembly, loss or incorrect loading.

7. The storage place should be equipped with sufficient fire-fighting equipment, and flammable materials should not be stored near the storage place to prevent fire.

8. The pipes leading to the inside of the calcium hydroxide equipment, such as the water inlet and outlet, oil injection port, exhaust hole and inspection hole, etc. The pipe joints should be wrapped and covered, especially the upward pipe, and carefully blocked to prevent foreign matter from entering the cylinder.

9. The internal combustion engine machinery should be started once a month. If it cannot be started, it should be moved and rotated to lubricate its interior and prevent rust

The storage system of calcium hydroxide equipment

1. The newly purchased calcium hydroxide equipment will be replaced once in the first 300 hours of operation, working for more than 10 hours a day, and changing the oil every 2500 hours. If you work less than 10 hours a day, change the oil every 6 months.

2. The newly purchased calcium hydroxide equipment needs to be filled with butter in sequence until the cavity is completely filled. After that, it will be added every 3 months. Grease should be replaced every 12 months of operation.

GFX Stepped

3. The method of replacing the grease is to disassemble, take out the parts, clean, and then apply the grease weight specified during assembly. Before assembly, all parts should be spread evenly.

4. According to the specific conditions of the construction progress, when the equipment configured by the company is not in use, the project should repair and reform the deactivated equipment, and the technical conditions shall meet the prescribed secondary standards.

5. Within one month after the completion of the transformation, the company shall notify the Machinery, Materials and Equipment Department for acceptance in writing. After passing the inspection, the calcium hydroxide equipment will stop charging for these three items next month, otherwise, it will continue to refurbish until they pass the inspection.

6. During the renovation period, the Machinery and Materials Department will continue to charge for these three items.

According to the above calcium hydroxide equipment refueling principles and the content of the storage system, I believe everyone has a good grasp of the principles and methods of calcium hydroxide equipment refueling and oil change. In order to ensure the better operation of the equipment, as a staff member, it is necessary to regularly check the lubricating oil for timely addition and replacement.

How to improve the separation effect of calcium hydroxide equipment

/in /by

The size of the slurry sieve residue used in the calcium hydroxide production line and the size of the particle size distribution are related to the raw material lime and the production process. The quality of the raw material lime plays a dominant role. This is because the production process controls the preparation of the calcium hydroxide slurry. main effect. So as a manufacturer, how to improve the separation effect of calcium hydroxide equipment?

Methods to improve the separation effect of calcium hydroxide equipment:

1. The production process of calcium hydroxide production line should be adjusted timely and reasonably according to the change of raw materials, and the process parameters of calcium hydroxide slurry refining should be appropriately changed to provide high-quality calcium hydroxide slurry for the carbonization process to a certain level.

2. Disassemble and inspect the underflow holes of the hydrocyclone separators at all levels, like rubber rings, stop cleaning and replace them.

3. Each time the car is parked, pour the purified water into the outside of the hydrocyclone to stop thorough cleaning to prevent the calcium hydroxide slurry from clogging the underflow hole or scaling on the outside, which will increase the inducement of some secondary flow and cause rotation. The operating conditions of the liquid separator deviate from the design conditions.

4. Measure the characteristic sizes of the underflow holes like aprons of the hydrocyclone separators at all levels, and stop the cast iron processing according to the original design size, and then replace the aprons at all levels to increase the amount of abnormal production wear and ensure that the hydrocyclone is temporarily in the design Operating under working conditions to ensure separation effect.

5. Add a pair of pipelines between the inlet and outlet of the coarse slurry pump, adjust the opening of the coarse slurry pump inlet and outlet valve and the flow rate in the calcium hydroxide production line, and use the existing valves in the device to separate the two sets of hydrocyclones. The resistance of the filter system, grasp the flow and pressure, and make it reach the design working condition, thereby reducing part of the secondary flow induced by the change of external conditions, and making the particle size distribution of the sieve residue contained in the slurry more reasonable.

6. In the process of clinker calcination, there are two ways to generate tricalcium silicate from dicalcium silicate: self-synthesis from dicalcium silicate by solid-phase reaction to precipitate silicon oxide; or from dicalcium silicate and calcium oxide. A small amount of liquid phase completes the reaction.

7. Regardless of the method, the reaction is carried out in the original particles, but this will have a lot to do with the particle size of the raw meal of the calcium hydroxide production line. After the particle size is fixed, the crystal size of C2S and C3S is basically determined, especially The fineness of the silicon oxide-containing raw material is the key, because after calcium carbonate is decomposed, porous calcium oxide is formed, and the reaction proceeds by moving the silicon oxide into the pores of the calcium oxide.

The above is all about how to improve the separation effect of calcium hydroxide equipment. If the kiln as a system can no longer control the content of free calcium oxide in the clinker, it means that the kiln has been operating purely with disease. At this time, it was completely reliant on the operation of the central control operator and was already unable to do so. The management personnel (such as the chief engineer) should organize the strength to solve the problems that may arise in a targeted manner.

What are the powder selection methods for calcium hydroxide equipment?

/in /by

For the production of calcium hydroxide, the powder selection method of the calcium hydroxide equipment is also required. Generally, there are two powder selection methods adopted by calcium hydroxide equipment, namely cyclone dust collection method and cloth bag type collection method.

The powder selection method of calcium hydroxide equipment

1. Cyclone dust collection method

The air outlet of the fan is connected to the analyzer of the powder separator, the air outlet of the analyzer is connected to the spiral harvester, and the air outlet of the spiral harvester is connected to the air inlet of the fan. For such a cycle, a small dust collector is used to extract a small amount of air volume to compensate for the circulation generated by the closed connection of each pipeline. Leak, and make the air pressure in the entire circulation pipeline lower than the outside air pressure, and at the same time avoid leakage.

The material enters the powder separator room through the inlet located on the upper part of the powder separator room, and then falls on the spreading plate through the upper and lower cones of the medium and coarse powder collecting cone and the macaroni pipe. The driven shaft rotates, and the material is evenly scattered around under the action of inertial centrifugal force. The dispersed material is thrown away by the inertial centrifugal force under the action of the high-speed airflow from the external fan into the powder selection chamber through the air inlet. To the inner wall of the powder room.

After the collision, it loses kinetic energy and slides down the wall and falls into the coarse powder collecting cone. The remaining particles are rolled up by the rotating ascending airflow. When passing through the action area of ​​the large wind blade, under the impact of the large wind blade, a part of the coarse powder particles will be Throw to the inner wall of the powder selection chamber, lose kinetic energy after collision, slide down the wall, and fall into the coarse powder collecting cone.

The internal airflow is due to the addition of a dust collector on the closed circulation pipeline of the powder separator. The calcium hydroxide equipment chooses this method mainly because the wind is a closed circulation air, which has no limited emissions to the atmosphere and avoids pollution.

2. Bag-style collection of finished products

After passing through the large wind blades, the medium coarse powder and fine powder continue to rise through the vertical guide blades into the secondary powder selection area under the action of the updraft. Under the action of the strong and stable plane vortex formed by the rotating cage rotor, the dust-laden airflow causes the medium and coarse powder to lose kinetic energy after being thrown to the vertical guide vane under the action of centrifugal force, and fall into the medium and coarse powder collecting cone. The medium coarse powder tube is discharged.

If the calcium hydroxide equipment strictly controls the filter mesh number of the filter bag, because the calcium hydroxide will produce a small amount of very fine particles <1500 mesh during the natural decomposition, the wind will be directly discharged into the atmosphere after the finished product is collected by the bag filter. If a cloth bag is not used for collection, the pressure loss of the fan will be caused during the decomposition process, and the fan selection will be too large.

The above is all about the powder selection methods of calcium hydroxide equipment. In fact, we know that the overall purity and output of calcium hydroxide will be improved by a certain powder selection method. Calcium hydroxide equipment under the premise of the same output, because the bag type wind pressure loss is smaller than that of the cyclone type, but the power of the fan is higher than that of the cyclone type collection method.

What is the difference between calcium hydroxide equipment and traditional production processes?

/in /by

Crush the qualified calcium oxide (CaO) block material from the jaw crusher to a particle size of about 40mm, and transport it to the calcium oxide storage tank warehouse through a bucket elevator. The calcium oxide in the warehouse enters through the quantitative stabilization system of the steady flow conveyor The calcium hydroxide grade I digester performs preliminary digestion. After the calcium hydroxide completes the primary digestion, it enters the ii digestion or iii digestion device. The calcium oxide is completely digested and decomposed. The calcium hydroxide that is digested and decomposed by the qualified calcium hydroxide primary product is spiraled by the semi-finished product. The conveyor is transported to the pulverizer, and the pulverizer completes product impurity separation and fineness classification. After the classification is completed, the terminal qualified high-quality products are unloaded by the finished product conveyor and elevator to the finished calcium hydroxide tank for packaging respectively. All pollution nodes of the production line are completed by pulse dust collectors, with a dust removal rate of 99.5%.

The difference between calcium hydroxide equipment and traditional production technology

Advantage 1:

In China, the production process of calcium hydroxide is still dominated by handcrafted workshops. There are only a handful of calcium hydroxide manufacturers capable of mechanization and large-scale production. The calcium hydroxide produced in the manual workshop is mainly used in low-end markets such as sewage treatment, ash calcium, and putty powder. The production process and product quality have the following problems:

(1) Severe environmental pollution: Due to manual production, large amounts of high-temperature steam and dust generated during the digestion process are everywhere, and the dust pollution radius is at least 1,000 meters. The forests and crops within the contaminated area are seriously damaged and often cause disputes between the public and enterprises around the enterprise.

(2) In the past, the intensity was high and the scale was small: the production environment of such enterprises was extremely poor, and the labor intensity of workers was extremely high, which seriously affected the physical and mental health of production workers. The production efficiency is extremely low, no more than 1 ton of finished calcium hydroxide per person during the day. Although there are a large number of such enterprises, their scale is small, with an annual output of 5,000 tons and an annual output of several hundred tons. The production capacity cannot meet the large demand for calcium hydroxide in power plants, such as desulfurization, fine chemicals, medicine and food, petroleum, papermaking and other industries.

(3) The product quality is poor and unstable: Because it is produced manually, the production process depends on experience. The quality of the final product varies from time to time, which cannot meet the needs of petrochemical, fine chemical and other industries.

With the rapid expansion of the calcium hydroxide market, customers’ improvement in product quality, and the country’s emphasis on the environment, the calcium hydroxide market has given birth to a number of large-scale, highly mechanized production companies that meet national environmental protection requirements and have stable quality. . Meet market demand, reduce environmental pollution, improve the production environment of workers, and reduce labor intensity of workers.

In this context, GF, GFD, and GAD calcium hydroxide equipment has realized fully automatic control and online real-time inspection. The complete production line fully meets the requirements of the national environmental protection department, and the product fineness ranges from 200 to 600 mesh. The output of a single machine varies from 3T/h to 20T/h, and different schemes can be completed according to user requirements. The product quality fully meets industry requirements.

Advantage 2:

1. Inspection system:

Electronic means are used for rigid inspections, and inspectors sample unit time to ensure stable product quality and avoid quality problems caused by deviations in raw material production.

Electronic means are used for rigid assessment, and equipment maintenance personnel conduct inspections on the operation cycle of each part, so that problems can be solved in time when problems are found, and the equipment will be prevented from running with failures, thereby prolonging the service life of the equipment.

Using electronic hard inspection method, each operating part is lubricated to avoid oil-free operation and accidental wear.

2. On-site remote control

The equipment is remotely switched on and off in all parts of the equipment production area to deal with emergencies and avoid personnel and financial losses.

3. Discharge temperature

The discharge temperature is controlled at about 45°C, and the discharge water content is controlled at about 1%. Prevent agglomeration of the finished product, improve the efficiency of powder selection and waste discharge.

The above is all about the difference between the calcium hydroxide equipment and the traditional production process.

The calcium hydroxide production line is also called calcium hydroxide equipment. It is used to process calcium hydroxide. Through years of technological innovation, its performance and technology are getting higher and higher. Depending on the place of use, its installation form is different. Luoyang As a professional manufacturer of calcium hydroxide production line in China, Caofeng Industry and Trade will introduce to you the installation form of the equipment.

Stepped calcium hydroxide production line:

1. Consider this approach for companies with spacious venues.

2. It is a more traditional type of calcium hydroxide equipment, usually single shaft or double shaft, double stage and digestion method. Therefore, the installation area of ​​the digester of the equipment is much larger than that of the tower type.

3. Due to the large area of ​​the equipment, the sections can be well separated for maintenance during maintenance, which reduces unnecessary disassembly of components, and the stepped type can have a variety of arrangements, including L-shaped, straight-shaped, and U-shaped. It can be installed, and the installation method is highly adjustable.

How to deal with the high temperature of calcium hydroxide production line?

/in /by

Calcium hydroxide production line equipment is a very common milling equipment in the milling industry. After a period of use, large and small problems will always appear, and the way to solve the problem is the key. Therefore, the calcium hydroxide production line manufacturer gave us the following detailed introduction on how to deal with the high temperature of the calcium oxide production line equipment.

Treatment method for high temperature of calcium hydroxide production line:

1. Check whether the extension pipes are unobstructed, and whether the viscosity and grade of the oil meet the requirements;

2. The powder inlet bearing of the grinding roller device should be refueled in time according to regulations, cleaned regularly, and the oil seal should be replaced;

3. The bearings of the grinding roller and grinding ring should be refueled regularly;

4. The bearing room temperature should not exceed 70°C. If the bearing temperature is too high, immediately remove and clean the bearing and the bearing room and other accessories each need to be cleaned once;

5. Fan heating may be caused by high wind pressure. Sometimes we will unconsciously encounter the fan equipment during production, causing the motor to heat up due to changes in the fan’s wind pressure. This also reminds us not to change the equipment arbitrarily in production;

6. There is also the reason for the equipment itself, such as the quality is not good enough, choose big brand, high-quality equipment.

7. It is necessary to reduce the amount of feed, eliminate the powder accumulation in the air duct, and then open the remaining air pipe valves, and control the humidity of the incoming materials below 6%.

8. After being crushed into small particles by the hammer crusher, the bulk material is sent to the storage bin by the elevator, and then sent to the bulk tray on the upper part of the turntable through the vibrating feeder and the inclined feeding pipe. superior.

9. When working in a high-temperature environment, the environment temperature is high and the heat dissipation of the normal working calcium hydroxide equipment is added. Therefore, some devices in the calcium hydroxide equipment production line may experience heat generation due to continuous operation during the production process. If necessary, the calcium hydroxide equipment can be simply cooled down to avoid wear of the components.

10. Pay attention to electricity safety under high temperature operation, ensure that the circuit of the calcium hydroxide equipment production line workshop is unblocked, pay attention to some electrical safety of the calcium hydroxide equipment, and let the calcium hydroxide equipment use some electrical devices when necessary. And do a good job in the inspection of electrical installations in time, if the line is found to be aging or abnormal, it should be shut down in time for processing, and pay attention to production safety.

The above is about how to deal with the high temperature of the calcium hydroxide production line equipment. Calcium hydroxide production line equipment includes different phenomena of excessive temperature, such as fan motor heating and bearing temperature. The customer must first figure out the reason for the temperature increase, and then prescribe the right medicine.
