[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] like Figures 1 to 2 As shown,

[0019] A bag dust collector is characterized in that it includes a box body 2, an air inlet 3 is provided at the lower end of one side of the box body 2, an exhaust port 4 is provided at the upper end of the other side of the box body 2, a plurality of dust bags 5 are provided at the upper end of the box body 2, an ash hopper 6 is provided at the lower end of the box body 2, two cleaning boxes 7 are symmetrically provided on both sides of the middle of the box body 2, a first push rod motor 8 is provided on the outer side of the two cleaning boxes 7, a filter screen 9 connected to the push rod of the first push rod motor 8 is provided in the cleaning box 7, and through holes 10 connected to the cleaning box 7 are opened on both sides of the box body 2, and the filter screen 9 can pass through the through holes 10 into the box body 2.

[0020] In this embodiment, the dust-laden gas enters the box body 2 from the air inlet 3, and the larger waste particles fall directly into the ash hopper 6 at the lower end. The first push rod motor 8 on one side drives the filter screen 9 to move into the box body 2, so that the dust-laden gas first contacts the lower end of the filter screen 9 for preliminary filtration. The gas after preliminary filtration passes through the filter screen 9 and contacts the dust bag 5 for secondary filtration, and is finally discharged from the exhaust port 4. After one of the filter screens 9 has been used for a period of time, the used filter screen 9 is moved to the dust cleaning box 7 for cleaning by the first push rod motor 8, and the other filter screen 9 is moved to the box body 2 for use. The two filter screens 9 are used alternately to ensure the filtration efficiency of the filter screen 9; the dust-laden gas is pre-treated by the filter screen 9 to reduce the dust accumulated on the surface of the dust bag 5 and increase the service life of the dust bag 5.

[0021] In this embodiment, the housing 2 is provided with a pulse blower 11, which is equipped with a pulse air pipe 12. The upper end of the housing 2 is provided with several blowpipes 13 that extend into the dust bag 5. The lower ends of the pulse air pipes 12 are connected to the upper ends of the blowpipes 13. The pulse blower delivers compressed air into the blowpipes 13 through the pulse air pipes 12, which then pulse-clean the dust bag 5. During cleaning, the filter 9 moves into the dust cleaning box 7, and the dust falls into the ash hopper 6 at the lower end.

[0022] In this embodiment, sealing blocks 14 corresponding to the through holes 10 are provided on both sides of the filter screen 9, and the push rod of the first push rod motor 8 is fixedly connected to the sealing blocks 14. The sealing blocks 14 are provided to prevent dust-laden gas from entering the dust cleaning box 7.

[0023] In this embodiment, a cleaning frame 15 is slidably connected to the dust cleaning box 7. A cleaning rod 16 is rotatably connected to the cleaning frame 15. The cleaning rod 16 is provided with cleaning bristles 17, which are capable of contacting the lower end of the filter 9. The cleaning frame 15 is provided with a drive motor 18, the output shaft of which is connected to the cleaning rod 16. A second push rod motor 19 is provided outside the dust cleaning box 7, the push rod of which is connected to the cleaning frame 15. After the used filter 9 enters the dust cleaning box 7, the drive motor 18 drives the cleaning rod 16 and the cleaning bristles 17 to rotate, and the second push rod motor 19 drives the cleaning frame 15 to move back and forth, brushing off the dust remaining at the lower end of the filter 9, thereby ensuring the filtration efficiency of the filter 9.

[0024] In this embodiment, the lower end of the dust cleaning box 7 is slidably connected to a drawer 20. The dust brushed off the filter screen 9 falls into the drawer 20, which is convenient for dust processing.

[0025] In this embodiment, support legs 21 are provided at the lower ends of the box body 2 and the dust cleaning box 7 .
