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.

[0027] Reference Figures 1-2 , Figures 4-5 This utility model provides an embodiment of an electrostatic precipitator frequency conversion vibration device, comprising a housing 1, a housing 20 on one side of the housing 1, an inclined plate 2 fixedly connected to the bottom of the housing 20 and the housing 1, a fixed plate 4 fixedly connected to the outer wall of the inclined plate 2, a motor 5 fixedly connected to the upper surface of the fixed plate 4, a fixed column 37 fixedly provided at the output end of the motor 5, a ring 38 fixedly connected to one end of the fixed column 37, a rotating rod 21 rotatably connected to the middle of the ring 38, and one end of the rotating rod 21 penetrating through... The bottom end of the fixed rod 36 is rotatably connected to a ring 3. One side of the ring 3 is fixedly connected to the inner wall of the outer shell 20. The top end of the fixed rod 36 is rotatably connected to a shaft 39. Both ends of the shaft 39 are fixedly connected to a vibrating rod 7. The top end of the vibrating rod 7 is slidably connected to a fixing ring 6. The top end of the fixing ring 6 is fixedly connected to the middle of the lower surface of the filter plate 30. Several springs 35 are fixedly connected to the lower surface of the filter plate 30. The bottom end of the springs 35 is fixedly connected to a fixing plate 34. One end of the fixing plate 34 is fixedly connected to the inner wall of the outer shell 1.

[0028] Specifically, when the operator turns on motor 5, a fixing plate 4 is connected to the bottom of motor 5. The fixing plate 4 can fix motor 5 to prevent shaking during operation. The output end of motor 5 is connected to a fixing column 37. When the output end of motor 5 rotates, it drives the fixing column 37 to rotate. One end of the fixing column 37 is connected to a ring 38, so that the ring 38 rotates when the fixing column 37 rotates. A rotating rod 21 is connected to the middle of the ring 38. One end of the rotating rod 21 is connected to the ring 3. When the ring 38 rotates, it will... The rotating rod 21 rotates around the center of the second ring 38. The outer wall of the rotating rod 21 is connected to the fixed rod 36. As the second ring 38 rotates, the rotating rod 21 drives the fixed rod 36 to reciprocate. The top of the fixed rod 36 is connected to the second rotating shaft 39, and both ends of the rotating shaft 39 are connected to the vibrating rod 7. The fixed rod 36, through the rotating shaft 39, drives the vibrating rod 7 to reciprocate in the center of the fixed ring 6. The outer wall of the vibrating rod 7 is connected to the fixed ring 6, ensuring that the vibrating rod 7 does not deviate during its reciprocating motion. The top of the fixed ring 6 is connected to... The filter plate 30 allows the vibrating rod 7 to reciprocate more effectively. Springs 35 are connected around the filter plate 30, and the bottom of the springs 35 is connected to a fixing plate 34. The fixing plate 34 is connected to the outer casing 1, ensuring the filter plate 30 is stable. When the motor 5 starts, it drives the vibrating rod 7 up and down via the rotating rod 21 and the retaining ring 38.

The lower surface of the filter plate 30 is fixedly connected to the springs 35, and the springs 35 are connected to the vibrating rod 7. The vibration of the filter plate 30 knocks the dust adsorbed on the filter cartridge 31 off. At the same time, the elasticity of the spring 35 can drive the filter plate 30 to vibrate slightly. This vibration can shake off the dust attached to the surface of the filter plate 30. The vibration is generated by the cooperation of multiple mechanisms such as the motor 5 and the vibrating rod 7, thereby reducing the dust on the filter cartridge 31 and improving the air quality. This improves the problem of incomplete dust cleaning on the filter cartridge 31 by traditional electrostatic precipitators, which causes the filter cartridge 31 to become clogged due to incomplete dust cleaning.

The middle of sprocket 14 is fixedly connected to threaded rod 16. When sprocket 14 rotates... The sprocket 28 and the threaded rod 29 are fixedly connected. The movement of the sprocket 28 also rotates the threaded rod 29.

The upper surface of the fixed plate 23 is fixedly connected to the pump 22. The movement of the fixed plate 23 drives the pump 22 to move synchronously. When the pump 22 starts, the input end of the pump 22 is connected to the water source, and the output end of the pump 22 is fixedly connected to the output pipe 28. The pump 22 delivers water through the output pipe 28.

Small holes are provided on the output pipe to spray out a small amount of water mist. Through the cooperation of multiple mechanisms such as the motor 210 and the pump 22, an integrated processing flow is formed, thereby reducing the generation of secondary dust and further improving the air quality. This improves the traditional electrostatic precipitator frequency converter rapping device, which is affected by secondary dust.

[0037] Working principle: When the operator transmits dusty air through the middle of the outer casing 1 into the machine, the dust in the air is adsorbed onto the surface of the filter cartridge 31. Then, the motor 5 is started, and the continuous impact of the vibrating rod 7 shakes the dust adsorbed on the filter cartridge 31 off. When the dust is shaken off, the motor 10 is started, which drives the sliding block 17 to reciprocate. The middle of the sliding block 17 is connected to the output pipe 18. Then, the pump 22 is started. The input and output ends of the pump 22 spray water mist through the output pipe 18. The water mist sprays the dust that falls onto the filter cartridge 31 to prevent secondary dust generation. Then, the dust falls into the bottom of the outer casing 20. Then, the motor 12 is started, which drives the rotating shaft 33 to rotate. The rotating shaft 33 is equipped with fan blades 32. When the fan blades 32 rotate, they will transport the dust into the storage box 19. Then, the valve 26 is opened, and the dust is processed through the inclined plate 24.
