Daily maintenance of vibrating screen, cleaning and maintenance of vibrating screen

How to avoid dust in ultrasonic vibrating screens**:

1) Keep the production environment ventilated. One of the reasons for dust** is that the production environment is closed, so the dust cannot be discharged through the air circulation and accumulate in the production environment. Occurs if an open flame or high temperature is encountered**;

2) Carry out the dust-proof work of the ultrasonic vibrating screen. Clean the dust after each use of the device, especially near seals and vibrating motors.

3) Use explosion-proof motors. The vibrating motor used in ordinary vibrating screens does not have explosion-proof functions. However, when selecting flammable and explosive powder materials, in order to avoid **, it is necessary to ensure that no heat and open flames are generated during normal operation, so explosion-proof vibrating motors must be used.

Ultrasonic vibrating screens and tripping cleaning and maintenance reasons.

Clean and maintain the ultrasonic oscillator regularly to keep the surface clean and extend its lifespan.

Ultrasonic vibrating screens have three main aspects that can be cleaned and maintained regularly:

1.When cleaning stainless steel surfaces, be careful not to scratch the surface, avoid using bleach and cleaning fluids containing abrasives, steel balls, abrasive tools, etc.

2.To remove the cleaning solution, rinse the surface with clean water at the end of cleaning.

3.Contaminate stainless steel surface grease, engine oil and lubricating oil, wipe with a soft cloth, then clean with a mild detergent or ammonia or a special detergent.

When the ultrasonic vibrating screen works, there are several reasons for tripping.

One is the short-circuit aging of the power supply of the vibrating motor of the ultrasonic vibrating screen;

Secondly, the vibrating motor line is damaged and leaking;

Third, the bearing is damaged or lacks oil, resulting in the load tripping;

Fourth, the magnetic circuit performance of the vibrating motor is reduced, resulting in excessive current.

Fifth, the capacity of the air switch of the vibrating motor does not match or deteriorates with the current protector.

1. The flow of materials on the screen surface of the vibrating screen is abnormal.

1. The stiffness of the screen box is insufficient, there is a critical frequency, and the connecting bolts have been loosened, even to the extent of full loosening, that is, tightened.

2. The transverse level of the screen box is not accurate, find fault with the support seat or spring itself from the support seat of the support foot spring, change the spring or change the size of the bearing, and it is possible that the screen surface mesh is damaged, as long as the screen is replaced. If the stiffness of the screen box is insufficient, the transverse level is not accurate, which will cause the beam to break, and if it is still running, the material flow will be abnormal. It is also possible that the operation is not correct, i.e. the extremely unbalanced feeding is also one of the reasons.

Second, the vibrating screen cannot be started or the amplitude is too small.

In this case, you should check whether there is any obstacle in the electrical, whether the motor is damaged, or whether the components in the line are damaged, whether the voltage is insufficient, and then check from the mechanical: Whether the material on the screen surface of the rotary vibrating screen is accumulated too much, if so, it is cleared. Whether the coupling bolt on the exciter falls off, whether the grease becomes thickened and agglomerate, the exciter can be cleaned and repaired, and then the position of the eccentric shaft weight block or the auxiliary eccentric block can be appropriately adjusted.

3. The rotation of the vibrating screen slows down and the bearing heats up.

In this case, it means that the usual maintenance has not kept up, the bearing lacks grease, if it is a new grease, it is a quality problem of grease or too full, and the inferior oil makes the bearing block the labyrinth seal jam, so the quality of the grease is quite important.

Fourth, the screening quality of the vibrating screen is poor.

Most of the reasons are improper operation, which may cause the mesh to be blocked, the increase of fine particles and moisture in the sieving materials, so that the upper layer of the sieve is too thick, and the feeding is uneven, etc.; It may be that the two sides of the screen are not tightly pulled; If the shaft is eccentric and vibrating, the belt may be weak in dragging, the belt is too loose, and after the mechanical problems are dealt with, you can reverse rotate for a period of time to improve the screening quality.

5. The side plate of the vibrating screen is cracked, the beam is broken, and the structural parts are damaged.

This situation will not be sudden, it is too long to work at the critical frequency, such as a large number of high-strength bolts that tighten the side plate are relaxed, the serious deformation of the spring makes the difference between the left and right heights very much, and it is also possible that the weight error of each eccentric block is too large, causing damage to the structural parts, cracks in the wall panel, and even broken beams, replacing the damaged parts, tightening the bolts, when repairing the cracks in the wall panel, two 6mm small holes must be made at the second end to prevent the crack from extending, don't forget to make a few air holes in the reinforcing plate when repairing the reinforcing plate.

When using the vibrating screen, it should first be operated according to the operation instructions, and secondly, the daily maintenance and maintenance of the vibrating screen should also follow the following methods, so that the screening effect of the vibrating screen is better and the service life is longer.

1. Before the vibrating screen starts:

1) The coarse mesh and fine mesh should be checked for damage, and if there is damage, it should be replaced in time to ensure the screening effect;

2) There is also whether each set of bundle rings is locked.

2. When the vibrating screen is started:

1) Pay attention to whether there is abnormal noise, if there is noise, it may be that the equipment is faulty and needs to be stopped for inspection;

2) Whether the current is stable;

3) Whether there is any abnormality in vibration.

3. After the vibrating screen is used: clean it after each use.

The advantages of the vibrating screen are briefly summarized as follows:

1. Slag-liquid separation: The vibrating screening machine can quickly remove the insoluble solid substances in all kinds of slurry and discharge the slag continuously.

2. Sieving: The particles and powders can be divided into particle segments of different sizes. A single vibrating screen can be equipped with 5 screens, which can continuously sort 2-6 particle fractions and control a small particle size range.

3. Impurity removal: The high-performance vibrating screen machine can quickly remove large or small particles with low percentage content in the process of high-flow treatment.

1) For the first operation of the equipment, the first 7 working days are the trial operation stage of the machine, please check the equipment every day, and adjust the regular inspection time according to the lead condition of the hail oak equipment in the trial operation stage. The scope of inspection includes: the tightness of the fastening bolts of each part (e.g

Bundle ring bolts, motor fastening bolts), screen (sieve plate) for fatigue and damage.

2) Regularly check the fastening bolts of each part to prevent loosening;

3) Regularly check the screen for fatigue and damage.

4) Regularly check the fixing bolts of the supporting plate to prevent the bolts from loosening and causing the vibration cracking of the supporting plate.

5) Regularly check the fixing of the screen frame lock and adjust the Huai Sui bolt to prevent loosening or sick work.

6) Replenish the grease regularly and reasonably in strict accordance with the instruction manual of the vibrating motor.

As we all know, the chemical vibrating screen is completed by the continuous movement of the motor, so what are the consequences of not maintaining the chemical vibrating screen on a daily basis? What are the precautions for our daily maintenance? The following three circles will answer the question of the regular maintenance of the chemical vibrating screen.

During the whole operation, all parts and components are subjected to varying degrees of force. If there is no regular daily maintenance, it will cause wear and tear on the parts of the equipment in the first place. Different degrees of force over a long period of time will cause different degrees of wear and tear on various parts.

In addition to wear and tear, a lack of routine maintenance can also reduce the performance of the vibrating screen. When using a chemical vibrating screen after normal maintenance, it must be at a specific frequency to achieve good screening results, but this performance can only be maintained based on daily maintenance.

The daily maintenance methods of chemical vibrating screen are as follows:

1.When the vibrating stove is installed, it should be placed on a solid and flat platform and meet its foundation requirements.

2.When using the chemical vibrating screen, you should pay attention to whether there is any abnormal sound at any time, and check the temperature of the equipment frequently. Spot temperature changes at any time.

3.After maintaining the vibrating screen, it should be disassembled and cleaned once when it is used for about 500 hours each time, and the oil should be replaced with a new one.

The above is about the consequences of non-routine maintenance of chemical vibrating screens and the precautions for daily maintenance.

1. The machine should be equipped with electrical protection devices.

2. At the beginning of the operation of this machine, check the anchor bolts at least once a day to prevent loosening.

3. When the rotation direction of the motor does not meet the requirements, the phase sequence of the power supply can be adjusted.

4. The motor should be well lubricated, and the lithium grease (ZL-3) should be replenished once every two weeks or so, and an appropriate amount of lithium grease should be added through the oil cup when refueling. When sealed bearings are used, the motor is not fitted with an oil cup.

5. After the machine has been running for 1500 hours, the bearing should be checked and replaced immediately if there is serious damage.

6. When the machine is used again after being parked for a long time, the insulation resistance should be measured, which should be greater than the megohm for 500 volt megohmmeter measurement.

7. Before starting: (1) Check whether the coarse mesh and fine mesh are damaged (2) Check whether the transportation support is removed.

8. When starting: (1) Pay attention to whether there is abnormal noise (2) Whether the current is stable (3) Whether there is any abnormality in vibration 9. After use: clean up after each use.
