[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a dust removal device, comprising: a dust removal box 1 with multiple filter bags 8 inside; a fan 2 fixedly connected to one side of the dust removal box 1 to create a negative pressure inside the dust removal box 1; a cleaning mechanism placed outside the dust removal box 1, the cleaning mechanism having a blowpipe 7 for cleaning the filter bags 8, the air outlet of the blowpipe 7 corresponding one-to-one with the filter bags 8; a fixed pipe 10 fixedly connected to the outside of the dust removal box 1, the end of the fixed pipe 10 being rotatably connected to a swing pipe 5, one end of the swing pipe 5 being provided with a reciprocating drive part for driving the swing pipe 5 to swing back and forth.

[0024] It should be noted that the dust collector of this utility model has multiple filter bags 8 inside for filtering dust or pollutants in the air; the fan is fixed to one side of the dust collector to create negative pressure, drawing air out of the dust collector and causing dust to accumulate on the filter bags; the cleaning mechanism is located on the outside of the dust collector and is mainly used to clean the filter bags; the air outlet of the blowpipe corresponds one-to-one with the filter bag 8 to blow air into the filter bag and remove the dust accumulated on the surface of the filter bag; the fixing pipe is fixed to the outside of the dust collector to support and stabilize the reciprocating drive unit; one end of the swing pipe rotates with the fixing pipe 10. One end is connected to the moving part, and the other end is connected to the reciprocating drive unit. Through the action of the reciprocating drive unit, the swing tube can swing back and forth. Through the reciprocating motion of the swing tube, the swing tube drives the air inlet to swing left and right, so that the position of the air inlet changes continuously, avoiding the airflow from concentrating in a fixed position. This can effectively avoid the phenomenon of excessive local dust accumulation or blockage caused by the air inlet being in a fixed position for a long time. The continuous swing of the air inlet can ensure that more air flows into different areas of the dust collector, which helps to improve the uniformity of airflow and dust distribution.

[0025] Please see Figure 1 , 2 As shown in Figures 3 and 4, the input end of the fan 2 is fixedly connected to the exhaust pipe 3. One end of the exhaust pipe 3 is connected to the dust collection box 1 and is located above the filter bag 8. The fixed pipe 10 is located on the side away from the fan 2 and below the filter bag 8.

[0026] It should be noted that the input end of the fan 2 of this utility model is connected to the exhaust pipe 3, and the other end of the exhaust pipe is connected to the top of the dust collection box 1. The fixed pipe 10 is located on the side away from the fan 2 and below the filter bag 8. It is used to introduce the airflow into the dust collection box from below, forming an effective airflow path, ensuring that the air enters the dust collection box from below the filter bag and is then filtered by the filter bag 8. The airflow enters the filter bag 8 from below, and after being filtered by the filter bag, the clean airflow is discharged from the dust collection box and finally guided to the fan 2 through the exhaust pipe 3. The fan 2 then discharges the filtered air out of the system.

[0027] Please see Figure 2 , 3 As shown, the cleaning mechanism also includes an air compressor 4, the air outlet of which is connected to each blowpipe 7 via an electromagnetic pulse valve.

[0028] It should be noted that the air compressor 4 of this utility model provides high-pressure airflow through compressed air to enable effective jet cleaning of the filter bags. The air compressor's outlet sends compressed air into an electromagnetic pulse valve; the outlet of the air compressor 4 is connected to each jet pipe 7 via the electromagnetic pulse valve. The electromagnetic pulse valve's function is to open and close the airflow periodically or as needed according to the control system's instructions to generate pulse jet cleaning. Upon receiving a control signal, the electromagnetic pulse valve opens instantaneously, rapidly blowing high-pressure air from the air compressor 4 into the jet pipes 7 through the pipes. The outlets of the jet pipes 7 correspond one-to-one with the filter bags 8. When compressed air is ejected through the jet pipes, it generates a strong airflow impact, quickly removing dust accumulated on the filter bag surface. Each jet pipe 7 has multiple outlets and corresponds one-to-one with the filter bags 8. These air outlets can be directly aimed at the surface of the filter bag. When the electromagnetic pulse valve is opened, compressed air will be sprayed out from these nozzles, thereby impacting and cleaning the accumulated dust. Each pulse jet will clean the filter bag, blowing off the dust attached to the surface of the filter bag, making it easy to collect and clean from the bottom of the dust collection box 1.

[0029] Please see Figure 1 , 2 As shown in Figures 4 and 5, the swing tube 5 has an L-shaped structure. An air inlet 6 is provided on one side of the top of the swing tube 5. A limiting round box 9 is fixedly connected to one end of the bottom of the swing tube 5. A fixing plate 11 is fixedly connected to one end of the fixed tube 10. The fixing plate 11 is rotatably installed in the limiting round box 9. A spur gear 12 is fixedly connected to the outside of the limiting round box 9. A limiting rod 16 is fixedly connected to one side of the dust collector 1. A drive rack 17 that meshes with the spur gear 12 is slidably connected to the outside of the limiting rod 16. A reciprocating screw 15 is threadedly connected to the middle of the drive rack 17. A worm gear reducer 13 is connected to one end of the reciprocating screw 15. The worm gear reducer 13 is fixedly connected to the dust collector 1. A motor 14 is fixedly connected to the input end of the worm gear reducer 13.

[0030] It should be noted that the L-shaped structure of the swing tube 5 of this utility model allows it to effectively cover different parts of the filter bag during operation, thus achieving more comprehensive cleaning. The limiting round box 9 is located at the bottom of the swing tube 5, which restricts the movement of the swing tube. The limiting round box 9 ensures that the swing tube 5 can rotate within a preset space without falling off or separating. The fixing plate 11 is fixed to one end of the fixing tube 10 to support and stabilize the entire swing tube system. A spur gear 12 is fixedly connected to the outside of the limiting round box 9. The spur gear 12 meshes with the drive rack 17 to achieve the reciprocating rotation of the spur gear 12. The outside of the drive rack 17 is slidably connected to the limiting rod 16 and meshes with the spur gear 12, driving the drive rack to reciprocate left and right through gear transmission. Driven by the motor and worm gear reducer 13, the reciprocating screw 15 drives the drive rack 17 to slide back and forth on the outside of the limit rod 16. The drive rack 17 drives the spur gear 12 to rotate back and forth. This causes the limit box 9 and the swing tube 5 connected by the spur gear 12 to swing back and forth. By swinging left and right, the air inlet can cover a wider area, ensuring that dust in every corner can be effectively sucked up, thus avoiding the problem of insufficient local dust suction. Fixed-position dust suction may lead to uneven dust suction, with some areas being over-sucked while other areas are under-sucked. The left and right swinging design helps to achieve a more uniform dust suction effect.
