[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-4 This utility model provides a circulating air purification type single-unit bag filter dust collector, including a dust collection box 1. A partition 22 is fixedly connected inside the dust collection box 1, and a hollow tube 2 is provided on the front side of the dust collection box 1. The partition 22 divides the interior of the dust collection box 1 into two dust collection chambers 23. Two connecting pipes 4 are connected to the rear side of the hollow tube 2, and an air inlet pipe 3 is connected to the front side of the hollow tube 2. The two connecting pipes 4 are connected to both dust collection chambers 23. A horizontal shaft 7 passes through the interior of the hollow tube 2, and two pistons 21, matching the hollow tube 2, are sleeved and fixedly connected on the horizontal shaft 7. The pistons 21 are positioned within the hollow tube 2. Inside the dust collector 1, a U-shaped part 16 is fixedly installed on the front side. Inside the U-shaped part 16, a lead screw 17 and a slider 18 are rotatably installed and slidably connected. A servo motor 19 is fixedly installed on one side of the U-shaped part 16. One end of the lead screw 17 is fixedly installed to the output end of the servo motor 19. The slider 18 is threadedly connected to the lead screw 17. A connecting part 20 is fixedly connected to the bottom of the slider 18. Connecting shafts 5 are symmetrically fixedly installed on both sides of the connecting part 20. A connecting part 6 is fixedly installed at one end of the connecting shaft 5. Both ends of the horizontal shaft 7 are fixedly installed to the two connecting parts 26. In this technical solution, the required dust removal gas is injected into the air inlet pipe 3, and then the servo motor 19 drives the lead screw 17 to rotate. The lead screw 17 drives the slider 18 to move laterally along the U-shaped part 16. The slider 18 drives the horizontal axis 7 to move laterally through the first connector 20, the connecting shaft 5 and the second connector 6. The horizontal axis 7 drives the two pistons 21 in the hollow tube 2 to move, thereby opening one connecting pipe 4 while closing the other connecting pipe 4. That is, while cleaning one dust removal chamber 23, the other dust removal chamber 23 can still be cleaned. This allows for cleaning without stopping the machine, increasing work efficiency.

[0017] In some technical solutions, such as Figure 4 As shown, a matching support plate 24 is fixedly connected inside the dust removal chamber 23, and an exhaust pipe 10 is connected to the upper side of the dust removal chamber 23. A filter bag 25 is installed through and fixedly mounted on the support plate 24.

[0018] In use, the dust in the gas is blocked by the filter bag 25, and the gas passes through the filter bag 25 into the top of the dust removal chamber 23, and is finally discharged through the exhaust pipe 10.

[0019] In some technical solutions, such as Figure 1 and Figure 4 As shown, a pulse pump 8 is fixedly installed on the front side of the dust collector 1. Several pulse tubes 9 are connected to the pulse pump 8. The pulse tubes 9 pass through the front side of the dust collector 1 and are located inside the dust collection chamber 23. Several nozzles 26 that match the filter bags 25 are connected to the pulse tubes 9. The nozzles 26 are located above the filter bags 25.

[0020] In use, pulse gas is injected into the pulse tube 9 through the pulse pump 8, and then the pulse gas is sprayed into the filter bag 25 through the nozzle 26, which washes off the dust that is blocked and attached to the filter bag 25, thus achieving automatic dust removal. This ensures that the filter bag 25 can still be reused without being disassembled, and also increases the speed and efficiency of dust removal.

[0021] In some technical solutions, such as Figure 1 and Figure 4 As shown, the bottom of the dust removal chamber 23 is connected to the ash discharge pipe 11, and a solenoid valve 12 is installed on the ash discharge pipe 11.

[0022] In use, dust can be discharged from the ash discharge pipe 11 by opening the solenoid valve 12 on the ash discharge pipe 11.

[0023] In some technical solutions, such as Figure 1 and Figure 4 As shown, a matching cover 13 is fixedly installed on the top of the dust collection box 1.

[0024] When in use, the dust collection box 1 can be easily opened through the cover 13 to inspect the interior of the dust collection chamber 23.

[0025] In some technical solutions, such as Figure 1 As shown, a rectangular frame 14 is welded to the outer wall of the dust collection box 1, and support legs 15 are fixedly installed at the four corners of the bottom of the rectangular frame 14.

[0026] When in use, the stability of the dust collector is increased by the support legs 15 at the four corners of the bottom of the rectangular frame 14.

[0027] Working principle: During use, the required dust removal gas is injected into the hollow tube 2 through the inlet pipe 3. The servo motor 19 drives the lead screw 17 to rotate, and the lead screw 17 drives the slider 18 to move laterally along the U-shaped part 16. The slider 18 drives the horizontal axis 7 to move laterally through the connecting part 1 20, the connecting shaft 5 and the connecting part 2 6. The horizontal axis 7 drives the two pistons 21 in the hollow tube 2 to move, thereby opening one connecting pipe 4 and closing the other connecting pipe 4 at the same time. The gas enters the corresponding dust removal chamber 23 through the opened connecting pipe 4. The filter bag 25 blocks the dust in the gas. The gas passes through the filter bag 25 and enters the top of the dust removal chamber 23. Finally, it is discharged through the exhaust pipe 10. The pulse pump 8 injects pulse gas into the pulse pipe 9. The pulse gas is then sprayed into the filter bag 25 through the nozzle 26, washing off the dust that is blocked and attached to the filter bag 25, thus realizing automatic dust removal.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
