The fixing ring and the collecting bucket are integrally formed, the fixing ring is located on the top of the collecting bucket, the two sides of the fixing ring are installed with connecting blocks for screwing the dust outlet, and the bottom surface of the collecting bucket is knitted with a dust bag.

Preferably, both sides of the dust outlet passage at the bottom of the collection box are provided with threaded holes for connecting the dust collecting device.

Preferably, the air outlet pipe is located under the dust removal net, and protective plates are welded on both sides of the dust removal box.

Preferably, the air pipe, the air intake box, the support column, the collecting hopper of the dust removal box, the fixing ring and the connecting block are all made of stainless steel.

Compared with the prior art, the present invention has the following advantages: the present invention is simple in structure, reasonable in design, and low in cost; the gas to be treated enters the air intake box through the air intake pipe, and after precipitation, enters the dust removal box through the air delivery pipe, and is filtered After being double-filtered by the valve and the filter, it is discharged from the air outlet pipe, and the dust flows into the dust collection bag through the dust outlet. The dust removal bag has good dust removal effect, is safe and reliable, and should be widely used.
