[0036] Embodiment 1:

[0037] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , the present utility model provides a technical solution: a dust removal device for a vacuum pump, including a processing box 1 and a vacuum pump body 23. A limiting groove 6 is opened at the top of the processing box 1, and a cover plate 7 is connected in the limiting groove 6. Multiple "W"-shaped anode dust collecting plates 12 and cathode dust collecting plates 13 are arranged at the bottom of the cover plate 7; Activity grooves 24 are opened at the bottoms of the anode dust collecting plate 12 and the cathode dust collecting plate 13. The multiple activity grooves 24 are on the same plane and are aligned. The anode dust collecting plate 12 and the cathode dust collecting plate 13 are both located in the processing box 1, and the anode dust collecting plate 12 and the cathode dust collecting plate 13 are arranged in a uniformly inserted manner; From both sides to the middle at the bottom of the anode dust collecting plate 12 and the cathode dust collecting plate 13, they are arranged in a "trapezoidal" shape, which can better process the air and prevent the unprocessed air from flowing out from below the processing box 1. A rotatable rotating shaft 14 is arranged at the bottom on one side of the inner wall of the processing box 1. The rotating shaft 24 is located in the activity groove, and the rotating shaft 14 is located below the anode dust collecting plate 12 and the cathode dust collecting plate 13. Multiple pushing assemblies 15 are connected to the rotating shaft 14; The multiple pushing assemblies 15 respectively cooperate with the multiple activity grooves 24 in a one-to-one correspondence. The pushing assembly 15 includes a push plate 154 that can be lifted, and the multiple push plates 154 respectively cooperate with the anode dust collecting plate 12 and the cathode dust collecting plate 13 in a one-to-one correspondence.

[0038] Specifically, the distance between any point on one side of the anode dust collecting plate 12 and any point on the cathode dust collecting plate 13 is greater than zero. A lifting ring 8 is connected to the top of the cover plate 7, and a plurality of support plates 9 are connected to the bottom of the cover plate 7. A chute 10 is provided on each of the plurality of support plates 9. Two chutes 10 form a group, and a sliding baffle 11 is slidably connected in the two chutes 10. The anode dust collecting plate 12 and the cathode dust collecting plate 13 are respectively connected to the bottom of the sliding baffle 11. By adopting the above technical solution, due to the certain distance between the anode dust collecting plate 12 and the cathode dust collecting plate 13, the air to be treated can pass through smoothly, and the treatment effect is good. Through the support plates 9 and the chutes 10, it is convenient for the dust collecting plate to move under the push of the push plate 154, and when the dust collecting plate is damaged, a single replacement and repair operation can be carried out.

[0039] Specifically, the pushing assembly 15 includes a fixed block 151, the fixed block 151 is connected to the rotating shaft 14, a receiving groove 152 is provided on one side of the fixed block 151, a telescopable telescopic rod 153 is connected to one side of the receiving groove 152, the output end of the telescopic rod 153 is connected to one side of the push plate 154, and a spring 155 is sleeved on the telescopic rod 153.

Through the cooperation of the rotating shaft 14, the push plate 154 can continuously push and lower the dust collecting plate, so that the dust adsorbed on the dust collecting plate can fall smoothly.

[0040] Embodiment Two:

[0041] On the basis of Embodiment One, please refer to Figure 2 and Figure 6 .

[0042] Specifically, the processing box 1 is connected to the input end of the vacuum pump body 23 through the mounting seat 4 at one end of the air delivery pipe 3. An indicating strip 5 is connected to the surface of the air delivery pipe 3. A driving motor 16 is connected to one side of the processing box 1. One end of the rotating shaft 14 passes through the processing box 1 and is connected to the output shaft of the driving motor 16. By adopting the above technical solution, through the mounting seat 4, it is convenient to connect the processing box 1 with the vacuum pump body 23, facilitating operation. Through the driving motor 16, when the vacuum pump body 23 stops working, it drives the rotating shaft 14 to rotate, driving the pushing assembly 15 to rotate around the rotating shaft 14, thereby pushing the dust collecting plate through the pushing assembly 15. On the other side of the processing box 1, an air inlet end 19 is provided. Fixing plates 20 are connected to both the top and bottom of the air inlet end 19. The air inlet end 19 is connected to a fixing frame 21 through the two fixing plates 20. A filter window 22 is provided on one side of the fixing frame 21. The filter window 22 communicates with the processing box 1. A discharge port 17 is provided at the bottom of the processing box 1. A storage box 18 is connected to the bottom of the discharge port 17. By adopting the above technical solution, through the fixing plates 20, the fixing frame 21 and the filter window 22, some larger debris carried in the air is processed. Through the discharge port 17 and the storage box 18, the dust falling on the dust collecting plate is collected, facilitating unified processing by the staff.

[0043] The working principle of the present utility model is as follows: When in use, the staff aligns the air outlet end 2 of the processing box 1 with the position of the input end of the used vacuum pump, brings the mounting seat 4 close to the input end of the vacuum pump, and fixes it with bolts, thereby installing the processing box 1 at the input end of the vacuum pump. Through the operation of the vacuum pump, the input end of the vacuum pump evacuates the inside of the processing box 1 through the air delivery pipe 3 on one side of the processing box 1, creating a negative pressure state inside the processing box 1, causing the outside air to enter the processing box 1 at the air inlet end 19 of the processing box 1. After passing through the filter window 22 provided on the fixing frame 21, some larger debris in the air is filtered to avoid affecting subsequent processing operations;

[0044] The air enters the processing box 1 through the filter window 22 on one side of the fixing frame 21. It is powered by an external high-voltage power supply to make the anode dust collecting plate 12 and the cathode dust collecting plate 13 start to work. An electric field is formed between the anode dust collecting plate 12 and the cathode dust collecting plate 13. By adjusting the voltage of the high-voltage power supply, the intensity of the electric field can be adjusted, so as to be adjusted and used according to different requirements. When the dust-containing gas passes through the electric field, the gas molecules are ionized at a sufficiently high voltage to generate ions. The dust particles collide with the ions and carry charges, which causes the dust particles to be affected by forces in the electric field; the charged dust particles move towards the electrode plate with the opposite electric property under the action of the electric field force, thereby adsorbing the dust on the opposite sides of the anode dust collecting plate 12 and the cathode dust collecting plate 13. The air after processing the dust is unobstructed and is discharged from the air outlet end 2 of the processing box 1 after flowing, and enters the input end of the vacuum pump through the air delivery pipe 3, so as to be pumped out by the vacuum pump;

[0045] When the vacuum pump stops working, the dust adsorbed on the anode dust collecting plate 12 and the cathode dust collecting plate 13 falls downward under the influence of gravity and drops into the storage box 18. The driving motor 16 on one side of the processing box 1 starts to work, driving the rotating shaft 14 to rotate in the processing box 1, driving the fixing block 151 on the rotating shaft 14 to rotate, driving the push plate 154 on one side of the fixing block 151 to rotate with the rotating shaft 14 as the center, and driving the push plate 154 to rotate and contact the bottom of the anode dust collecting plate 12 and the cathode dust collecting plate 13 in the same way. When continuously rotating, the push plate 154 pushes the anode dust collecting plate 12 to rise, driving the sliding baffle 11 at the top of the anode dust collecting plate 12 to rise in the chute 10. After the top of the sliding baffle 11 contacts the top of the chute 10, the anode dust collecting plate 12 stops rising. When the push plate 154 rotates again, it compresses the telescopic rod 153 between the push plate 154 and the storage groove 152, driving the telescopic rod 153 to shorten and compressing the spring 155 on the telescopic rod 153 until the push plate 154 rotates to the other side of the rotating shaft 14, the push plate 154 leaves the bottom of the anode dust collecting plate 12 and no longer contacts the anode dust collecting plate 12. The spring 155 rebounds, pushing the push plate 154 and driving the telescopic rod 153 to extend, so that the push plate 154 is reset. After the anode dust collecting plate 12 no longer receives the thrust of the push plate 154, the sliding baffle 11 descends in the chute 10, driving the anode dust collecting plate 12 to descend, and the anode dust collecting plate 12 is reset under the influence of gravity, thereby pushing the anode dust collecting plate 12 to make the anode dust collecting plate 12 shake, so that the dust adsorbed on the anode dust collecting plate 12 can completely fall into the storage box 18, which is convenient for the staff to carry out unified treatment;

[0046] When a single anode dust collecting plate 12 and cathode dust collecting plate 13 are damaged or malfunction, the staff can take out the cover plate 7 in the limit groove 6 through the lifting ring 8, so as to take out the anode dust collecting plate 12 and the cathode dust collecting plate 13 at the bottom of the cover plate 7, and then replace the single damaged dust collecting plate, which is convenient for maintenance, saves resources and is easy to operate.

[0047] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
