A top cover 2 is screwed to the top of the first pulse dust collector 1, and the inlet pipe 3 is connected through the top of the top cover 2. The outlet pipe 5 is located on one side of the first pulse dust collector 1. A base plate 4 is screwed to the bottom of the first pulse dust collector 1, and an air supply pipe 6 is connected to one end of the outlet pipe 5. Two fixing plates 7 are fixedly connected to the inner side of the first pulse dust collector 1, and the filter screen 8 is positioned between the two fixing plates 7. An installation mechanism is provided at the connection between the filter screen 8 and the fixing plate 7. The structure includes a first pulse dust collector 1 with a second pulse dust collector 9 on one side and a third pulse dust collector 10 on one side of the second pulse dust collector 9. A pulse mechanism 19 is located on the back of the first pulse dust collector 1. In use, the gas to be filtered enters the first pulse dust collector 1 through the inlet pipe 3 and is filtered by the filter screen 8. Then, the gas is discharged into the second pulse dust collector 9 through the outlet pipe 5 and the supply pipe 6 for secondary filtration. Finally, it enters the third pulse dust collector 10 for tertiary filtration, thus achieving a multi-stage filtration effect. The outlet pipe 5 of the third pulse dust collector 10 is connected to a fan to draw out the filtered gas.

[0019] For better filtration, the outlet pipe 5 of the first pulse dust collector 1 is connected to the inlet pipe 3 at the top of the second pulse dust collector 9 via the air supply pipe 6.

[0020] For better filtration, the outlet pipe 5 of the second pulse dust collector 9 is connected to the inlet pipe 3 at the top of the third pulse dust collector 10 via the air supply pipe 6.

[0021] To facilitate the installation of the filter screen 8, the installation mechanism includes a fixing bracket 11, a slide 12, a slot 13, an insert block 14, a connecting plate 15, a through groove 16, a slider 17, and bolts 18. The fixing bracket 11 is fixedly connected to the top of the fixing plate 7. The top of the fixing bracket 11 has a slide 12. The top of the fixing bracket 11 has a slot 13. The insert block 14 is inserted into the inner side of the slot 13. The top of the insert block 14 is fixedly connected to the connecting plate 15. The connecting plate 15 has a through groove 16 on one side. The slider 17 is fixedly connected to one side of the through groove 16. The outer side of the slider 17 is threaded. With bolt 18, when installing filter screen 8, simply insert the plug 14 at the bottom of the connecting plate 15 on one side of filter screen 8 into the slot 13 on the fixing plate 7. During insertion, the slider 17 in the through groove 16 will slide and connect to the slide groove 12. After insertion, the through hole on the outside of the fixing bracket 11 coincides with the threaded hole on the outside of the slider 17. Then, use bolt 18 to pass through the through hole and thread it to the threaded hole to fix the slider 17. This completes the installation of filter screen 8. The insertion of the plug 14 into the slot 13 makes it easier for the slider 17 to slide into the slide groove 12, making installation more convenient.

[0022] Furthermore, the inner wall of the groove 12 matches the outer wall of the slider 17, and the inner wall of the slot 13 fits against the outer wall of the insert 14.

[0023] Furthermore, the connecting plate 15 is connected to the filter screen 8.

[0024] Working principle: During use, the gas to be filtered enters the first pulse dust collector 1 through the inlet pipe 3. The gas is filtered by the filter screen 8, and then discharged into the second pulse dust collector 9 through the outlet pipe 5 and the supply pipe 6 for secondary filtration. It then enters the third pulse dust collector 10 for tertiary filtration, thus achieving a multi-stage filtration effect. The outlet pipe 5 of the third pulse dust collector 10 is connected to a fan to suck out the filtered gas. When installing the filter screen 8, simply insert the plug 14 at the bottom of the connecting plate 15 on one side of the filter screen 8 into the slot 13 on the fixing plate 7. During insertion, the slider 17 in the through groove 16 will slide and connect to the slide groove 12. After the insertion is completed, the through hole on the outside of the fixing bracket 11 coincides with the threaded hole on the outside of the slider 17. Then, the bolt 18 is used to pass through the through hole and threadedly connect to the threaded hole to fix the slider 17. This completes the installation of the filter screen 8. The slot 13 and plug 14 make it easier for the slider 17 to slide into the slide groove 12, making the installation more convenient.
