Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model provides a dust collector with the function of automatically cleaning filter bags, including a dust removal box 1 and an ash bucket 2, the ash bucket 2 is located on the lower side of the dust removal box 1, and the ash bucket 2 Connected with the dust removal box 1, the side wall of the dust removal box 1 is provided with an air inlet 5 and an air outlet 6, and a horizontal partition is arranged inside the dust removal box 1, and the horizontal partition divides the dust removal box 1 into upper and lower parts. Exhaust space 4 and filter space 3, air inlet 5 is connected with filter space 3, air outlet 6 is connected with exhaust hole, filter space 3 is provided with multiple filter bag frames, and filter bag frames are installed on the partition plate, A filter bag 7 is sleeved on each filter bag frame.

Others with dust enter the dust removal box 1 from the air inlet 5, and are filtered by the filter bag 7. The dust and the like are blocked outside the filter bag 7, and most of the trapped dust will gather in the ash hopper 2, while Some dust will adhere to the filter bag 7, and the filtered gas enters the exhaust space 4, and then is discharged from the air outlet 6, and after a period of time, the dust on the filter bag 7 will increase and affect the filter. Therefore, the dust on the outer surface of the filter bag 7 needs to be cleaned regularly.

For the cleaning of the dust on the outer surface of the filter bag 7, the utility model makes the following improvements,
