PRODUCTION PROCESS AND PRECAUTIONS OF CALCIUM HYDROXIDE EQUIPMENT

Calcium hydroxide equipment, also known as calcium hydroxide production line, is mainly used for the production of calcium hydroxide. With the increasing application of calcium hydroxide in industrial production, calcium hydroxide equipment has also been upgraded many times. There has been a qualitative change from performance to product. For the production process of calcium hydroxide equipment, everyone is not very clear, so in response to this problem, calcium hydroxide equipment manufacturers give you the following detailed introduction.

THE PRODUCTION PROCESS OF CALCIUM HYDROXIDE EQUIPMENT

GFEX Case

1. Pulverized calcium oxide

During production, the raw material calcium oxide (CaO) needs to be added into the silo, and then added to the jaw crusher evenly through the vibrating feeder, and crushed to a particle size of about 40 mm. The dust generated during the crushing process will be introduced into the pulse dust collector outside the workshop through the dust cover of the crusher through the induced draft fan. It is recommended to clean the calcium oxide powder in the dust collector once a week.

2. Digestive reaction

The crushed calcium oxide is lifted to the digester by the bucket elevator for digestion reaction. Calcium oxide needs to enter the first-level digester for preliminary digestion. When the primary digestion is completed, it will enter the second-level digestion or the third-level digester, so that the calcium oxide can be fully digested and decomposed to generate qualified calcium hydroxide primary products. Can reach 98%.

The feed port of the digester is designed with a screw feed propeller to facilitate material transportation. Most of them adopt a double-shaft stirring structure, which has the functions of stirring, crushing agglomeration and self-cleaning. Its unique paddle and stirring formula can make calcium oxide and water fully and evenly mixed together, the reaction is more complete, and it plays a role in the agglomeration generated during the reaction.

What should I do if the vibrating screen discharges?

In daily production, during the use of the vibrating screen, a relatively obvious material conveying is suddenly not smooth, followed by the problem that the discharge is biased in a certain direction. To solve this problem, we must first find out the reason for the deviation of the material, and then find out how to solve the problem of the deviation of the vibrating screen. In response to the above problems, the vibrating screen manufacturer gave us a detailed introduction.

The reason for the deviation of the vibrating screen

High frequency dehydration vibrating screen

1. The vibrating screen has a long working time

The vibrating screen has a large workload and a long working life. For a large linear vibrating screen, due to its heavy weight, if coupled with repeated vibration and strong inertia for many years, some parts of the body will be loose, which will lead to vibration. The angle of the motor changes, so the phenomenon of discharge deviation occurs.

2. Uneven feeding

If the vibrating screen is feeding more or less, it is easy to cause unstable screening accuracy, and because of the more or less material, the force deviation of the material is large, and there is a problem that the discharge is biased to one side.

3. Exciter installation problem

The transportation and screening of materials by the vibrating screen is pushed by the vibration exciter to the material with a fixed magnitude of excitation force in a designed fixed direction. Therefore, if the material conveying is not good, it can basically be judged as a vibration exciter. There is a problem with the installation angle. Under normal circumstances, the manufacturer will perform precise installation, testing, and adjustment before the equipment leaves the factory to avoid the deviation of the excitation force direction, so this problem is generally not the cause of the new machine.

Introduction to the fluidization of powder particles

When the gas enters the powder layer from the lower part of the container, if the gas flow rate exceeds a certain value (0.015m/s for cement), the friction between the gas and the powder is equal to the weight of the powder, and the powder no longer depends on the flow. The bed supports, at this point they can move freely and flow from high to low, keeping the upper plane of the powder layer horizontal, similar to liquid properties.

If there are holes in the side wall of the container at this time, the powder can also be ejected from the holes. This is called the fluidization of the powder. The cement truck utilizes the fluidization characteristics of the powder to realize unloading. The function of the fluidized cloth is to make the compressed air form a fine and uniform airflow into the powder layer to fluidize the powder.

Why do concrete mixer trucks turn while walking?

Concrete mixer truck is a special truck used to transport concrete for construction. This type of truck is equipped with a cylindrical mixing drum to carry the mixed concrete. The power is transmitted to the hydraulic pump, the hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe, and the hydraulic motor converts the hydraulic energy into kinetic energy and transmits it to the mixing tank through the deceleration and torque increase of the reducer. The handle angle can realize the forward and reverse rotation of the mixing tank and the size of the rotating speed, so as to realize the operations of concrete charging, stirring, stirring and discharging. The concrete mixer truck will always keep the mixing drum rotating during transportation, so do you know why it needs to rotate while walking?

1. Improve the efficiency of use

concrete mixer truck

Concrete mixer trucks involve transportation time, and it takes a certain amount of time for concrete to travel from the manufacturer to the construction site. If the concrete mixer truck walks and turns on the road, the mixing time of the materials can be combined with the time of transportation on the road, which improves the utilization rate of time and improves the work efficiency. Especially in hot summer, the solidification of concrete can be prevented by continuous stirring. After all, for manufacturers and builders, the value of a truck of concrete is still great.

Common oil tank truck faults and solutions

In daily life, oil tank truck is a very common means of transporting dangerous goods, because its transportation objects are mostly all kinds of flammable and explosive oil products, so the safe transportation of oil tanker is the key of every tanker driver. What should be paid attention to, what are the common oil tank truck faults, and how should we deal with these problems? The following is a tank truck manufacturer–CIMC LINYU, to analyze the common oil tank truck faults and solutions.

Oil Tank truck faults can generally be divided into indirect failures and sudden failures. When a failure occurs, we need to first determine the cause of the failure, and then carry out targeted treatment.

1. The oil absorption of the oil tank truck is abnormal

The reasons for the abnormal oil absorption of the tanker are generally: there is no oil in the oil pump; the oil absorption depth is more than 5m; the valve opening position is not correct. To solve this problem, we can fill the oil tank to at least 10L, and adjust the valve to the appropriate position That’s it. If the fuel tank of the tanker cannot discharge oil, it may be an impurity oil discharge pipe. In this case, just cleaning the oil pipe can solve the problem.

2. The oil tank truck cannot absorb oil or absorb less oil

The reasons for the oil tanker not being able to absorb oil or the amount of oil being absorbed are: the suction pipe part is not tightly sealed; the gap of the oil pump is increased. At this time, we only need to make the seal tight, and check and repair the oil pump.

3. The power take-off box of the oil tank truck is abnormal

The reasons for the abnormality of the power take-off box of the tanker are as follows:

(1) The pressure of the car is insufficient, and the power take-off box is not in gear;

(2) The air path is not tightly sealed, and the power take-off box is fooled;

(3) The air chamber is damaged, and the power take-off box is not hooked;

(4) Too little lubricating oil or impurities in the power take-off box;

(5) Wear of power take-off parts

For the above problems, we usually only need to have enough air in the pneumatic power take-off box, so that the reading of the air pressure gauge is above 0.6Mpa, the air circuit is strictly sealed, check the air chamber in time, refuel or update the lubricating oil, dismantle and inspect, clean and replace the worn parts.

2. When working in a high temperature environment, we need to consider the safety and reliability of electricity consumption to ensure that the calcium hydroxide equipment and the circuit of the production line workshop are smooth. The calcium hydroxide equipment can be matched with some electrical equipment , and the detection of electrical equipment can be done in time. If it is found that the line is aging or abnormal, it should be stopped in time.

3. Do a good job in the anti-rust and anti-corrosion measures of the calcium hydroxide production line. Such as long-term rust prevention on exposed metal surfaces, that is, unpainted places: coating and electroplating processes can be used, and corrosion-resistant alloys can be used to prevent rust in the later stage. This work can be started from two aspects, one is to paint the equipment, and the other is to do a good job in post-maintenance and cleaning of the equipment to reduce the probability of rusting of calcium hydroxide equipment.
