Stand-alone dust collector structure, the shell is welded with steel plate and connected by screws. Including rubber sealing door, filter bag frame bracket, ash cleaning linkage mechanism, etc. The hopper is part of the housing with a pull-out dust drawer and the seal is a hermetically sealed material.

The filter bag is made of 208 polyester velvet cloth and includes a frame seal and a spring-loaded insertion pad. The high-frequency vibration generated by the electric power of the ash cleaning machinery is transmitted to the filter bag by the eccentric linkage mechanism for ash cleaning. Its control device is divided into two types: automatic control and manual control.

Automatic control means that when the fan is working continuously, the ash cleaning mechanism of the stand-alone bag filter will automatically vibrate and clean the ash at regular intervals, and the manual control will automatically work after the fan stops, and it will automatically stop after tens of seconds, and the ash cleaning motor can also be started at any time as needed, and the time of the ash cleaning time is adjusted by the user himself. The stand-alone dust collector is easy to install, easy to maintain, and can professionally set up the dust removal scheme according to needs.

1. After a period of use, if it is found that the bolts of each connection part are loose and the seals are aging and lose their sealing effect, they need to be replaced and tightened, and anti-rust painting should be carried out regularly.

2. If it is found that the resistance of the equipment exceeds the limited range and there is obvious dust accumulation at the air outlet, you can check and adjust it in the following table. Fault Symptom Fault CauseTroubleshooting Method:

1) Excessive dust accumulation in the filter bag.

2) Solenoid valve failure.

3) Overhaul solenoid valve and control system.

4) Clean and unblock the pipes.

5) Excessive oil and moisture content of compressed air causes filter bag sticking.

6) Clean the filter bag and replace the filter material in the filter tank.

7) Check that there is obvious dust accumulation at the air outlet of the fan.

8) Check whether the filter bag is broken.

9) Replace the filter bag regularly.

3. The equipment should be operated and kept by a special person, and the pulse controller should not be adjusted often except for turning on and off during normal use.

4. Before getting off work every day, open the drain valve switch at the bottom of the water processor and gas storage tank in the pipeline to drain the water.

5. If the solenoid valve is damaged, it should be repaired or replaced in time.

When the concentration in the dust collector reaches a certain value; The pulse valve turns on the air compressor and blows the air into the cloth bag, blowing off the dust (material) adsorbed outside the bag, and then discharged by the spiral at the bottom of the box.

In the pulse injection method, the time and interval of the injection may be set by the control cabinet.

Cleaning method of bag dust collector:

1) Gas cleaning: Gas cleaning is to use high-pressure gas or external atmosphere to blow back the filter bag to remove the dust on the filter bag. Gas cleaning includes pulse jet cleaning, reverse air cleaning and reverse suction cleaning.

2) mechanical beating ash cleaning: divided into top beating ash cleaning and middle beating ash cleaning (all for the filter bag), is with the help of mechanical rapping device periodic vibrating each row of filter bags, in order to remove the dust on the filter bag.

3) Manual beating: It is to manually beat each filter bag to remove the dust on the filter bag.

Hello, "Jiuzheng Tongming" professional dust removal equipment team will answer for you!

The main structure of the dust collector is divided into four parts:

Purification part: It is composed of a filter bag, a filter bag bracket, a filter bag frame, a dusty gas inlet, a purified gas outlet, etc.

Injection part: It is composed of pulse controller, pulse valve, blowing pipe, air bag, etc.

Ash discharge part: It is composed of motor, reducer, screw ash conveyor, star ash discharge valve, etc.

Shell part: It is composed of an upper shell, a middle shell and a lower shell.

The exhaust fan introduces the dusty gas from the air inlet into the middle shell, and the clean gas penetrates the filter bag into the upper shell by the venturi tube, and is discharged from the net gas outlet, and the dust is blocked on the outer wall of the filter bag, with the extension of the filtration time, the dust adsorbed on the filter bag is getting thicker and thicker, and the resistance of the filter bag is getting bigger and bigger. The sharp expansion of the filter bag causes shock vibration, so that the dust adsorbed on the surface of the filter bag shakes off the ash hopper and is discharged by the ash conveyor.

(1) Management personnel should be familiar with the principle, performance, and use conditions of the dust collector, and master the adjustment of operating parameters and equipment maintenance methods.

2) During the operation of the equipment, a special person should be set up to manage it and make a record of the operation.

3) Regularly replenish lubricating oil on the lubricated parts on the pulse dust collector.

4) Frequently check whether the pulse cleaning system of the dust collector is sprayed normally, if it is abnormal, focus on checking whether the pulse valve diaphragm and solenoid valve are out of order or damaged, and should be repaired or replaced in time.

5) Regularly check the condition of the cylinder and the flange surface, and replace the sealing ring in time if air leakage is found.

6) If the pulse valve fails, it should be eliminated in time, if there are impurities, water and other foreign substances inside, it should be cleaned up in time, and the diaphragm should be replaced in time if it is damaged.

7) The sealing strip on the maintenance door should be replaced in time if it is aging. Regularly measure process parameters, such as gas volume, temperature, concentration, etc., and find abnormalities, the cause should be found and dealt with in time.

8) When stopping, after the process system is stopped, the dust collector and exhaust fan should be kept working for a period of time to remove moisture and dust in the equipment. At the same time, before the dust collector stops working, the ash cleaning and unloading operations must be carried out repeatedly. According to the change and fluctuation of the operating resistance of the equipment, regularly check whether the operation of the equipment is normal.

9) The filter bag is a wearing part, and the user should regularly check the working condition of the filter bag and consider replacing it in time according to the degree of damage to the filter bag.

10) Regularly check the working condition of the gas circuit system and ash discharge system, and eliminate the abnormality in time. According to the water accumulation in the water separator in the compressed air system, the water is discharged regularly.

Maintenance measures of bag filter: when a chamber is cleaned or repaired, it is necessary to close the main air valve and be in a state of shutdown, at this time, the treatment air volume is completely borne by other chambers, and the total filtration area of other chambers is called the net filtration area. That is, the net filtration area is equal to the sum of the total filtration area minus the number of cleaning chambers and maintenance chambers maintained in operation.
