When the staff cleans the air box pulse air bag and the low-pressure injection air bag, It is convenient for the dust in the pulse air bag of the air box and the low-pressure blowing air bag to enter the filter belt chamber.

Preferably, the low-pressure injection control valve is a low-pressure injection manual cut-off valve, which is convenient for staff to manually operate the low-pressure injection control valve.

Preferably, the air box pulse control valve is an air box pulse manual cut-off valve, which is convenient for staff to manually operate the air box pulse control valve.

As a preference, the air box pulse pipeline is arranged in parallel with the low-pressure injection pipeline, and both the air box pulse pipeline and the low-pressure injection pipeline are vertically arranged with the main pipeline, which is convenient for the staff to separately install the air box pulse pipeline and the low-pressure injection pipeline. The air box pulse control valve and low-pressure injection control valve on the pipeline are manually operated to prevent space position interference during manual operation of the air box pulse control valve and low-pressure injection control valve.

Compared with the prior art, the beneficial effect of the utility model is that the integrated bag type dust collector which is convenient for switching the dust removal method is convenient for switching the dust removal of the low-pressure blowing air bag and the pulse air bag of the air box, so the low-pressure Both the blowing air bag and the air box pulse air bag have good dust removal effect, and at the same time, the low pressure blowing air bag and the air box pulse air bag will not interfere with each other when cleaning, ensuring a better dust removal effect and facilitating work Personnel carry out dust removal operations on the low-pressure injection air bag and the air box pulse air bag respectively.
