Maintenance of Bag Type Dust Collector

Maintenance instructions for bag filter:

1. When the bag type dust collector is under maintenance, first cut off the power supply. The operator must carry the key of the operation panel and hang a sign "under maintenance, no operation" on the operation panel.

2. The transmission devices such as the rapping device, star unloader, exhaust fan, and couplings, transmission belts, transmission coupling wheels, etc., must be equipped with protective covers to prevent the bolts from loosening, causing the belts and chains broken to hurt people.

3. During the daily inspection or operation, the operator must strictly prevent the clothes from being twisted into the transmission device when handling the fault temporarily. When entering the ash collection hopper to clean the ash or entering the filter bag room to hang the bag, labor protection equipment must be worn to prevent dust from getting into the eyes or burning the skin.

4. For bag type dust collectors that handle flammable and explosive dust gas, such as bag dust collectors used in coal mills, the dust in the dust collector should be removed frequently to prevent combustion or explosion, and kindling material should be prevented from entering. It is strictly forbidden to use electric welding or gas welding to repair the pipeline or shell during operation.

5. For the positive pressure glass fiber bag type dust collector that handles high temperature gas, measures to prevent heat stroke should be taken when entering the gas distribution room to hang fiberglass filter bags in summer.

6. When entering the dust collector for treatment of harmful and toxic gases, it is necessary to prevent possible hypoxia and harmful gas poisoning accidents. The gas in the system can be replaced with air.

7. After the overhaul is over, you must carefully check whether there are tools or other sundries falling into the equipment. Check whether the protective cover is properly installed, and do not finish it carelessly.

8. When the equipment of the dust collection system is turned on and off, you must contact operators of other positions to get permission, after which you can start or stop in the order of on and off specified in the operating regulations.

The main maintenance items of the dust hood are as follows:

a. Whether the position of the mobile dust hood is correct.

b. Deformed or damaged state.

c. Whether the connection part with the pipeline is intact.

d. Confirm the dust accumulation status and clean it.

e. If a water cooling device is installed, check the displacement. The temperature of the drain and the presence or absence of leakage should be kept cool.
