Description

Technical Field

[0001] This utility model relates to the field of cyclone dust collector technology, and in particular to a spiral electrostatic cyclone dust collector. Background Technology

[0002] Cyclone dust collectors are a type of dust removal device. The dust removal mechanism is to make the dust-laden airflow rotate, and use centrifugal force to separate dust particles from the airflow and collect them on the wall of the device. Then, gravity causes the dust particles to fall into the ash hopper. Spiral electrostatic cyclone dust collectors combine the principles of cyclone separation and electrostatic adsorption. They separate coarse dust by centrifugal force and capture fine dust by high voltage electric field to achieve graded purification of dust with different particle sizes. However, when a cyclone dust collector is in use, due to the stickiness of the dust particles themselves, the electrostatic adsorption force, and the turbulence of the airflow, some dust particles will adhere firmly to the inner wall of the dust collector body. Long-term accumulation will gradually narrow the airflow channel, weaken the centrifugal separation effect and the electric field adsorption capacity, resulting in a significant decrease in dust removal efficiency. Therefore, we need to consider how to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a spiral electrostatic cyclone dust collector. It is equipped with a sliding plate, a striking ball, and a cam. The cam drives the sliding plate to move the striking ball to reciprocate and strike the dust collector body, shaking off the dust particles adhering to its inner wall and preventing dust particles from accumulating and affecting the dust removal efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A spiral electrostatic cyclone dust collector includes a dust collector body. A support frame is fixedly connected to the outer wall of the dust collector body. An air outlet pipe is fixedly connected to the upper end of the dust collector body, an air inlet pipe is fixedly connected to the outer wall of the dust collector body, and a dust discharge pipe is fixedly connected to the lower end of the dust collector body. Two sliding grooves are symmetrically opened at the upper end of the support frame. Sliding plates are slidably connected to the bottom of each of the two sliding grooves. Moving rods are fixedly connected to opposite sides of each of the two sliding plates. Two fixed plates are fixedly connected to the upper end of the support frame. The opposite ends of each of the two moving rods pass through the corresponding fixed plates and are fixedly connected to connecting plates. Striking balls are embedded on opposite sides of each of the two connecting plates. The two striking balls cooperate with the dust collector body. Springs are sleeved on the outer walls of each of the two moving rods. The two ends of each spring are elastically connected to the side walls of the corresponding sliding plates and the side walls of the fixed plates, respectively.

[0005] Preferably, four mounting plates are fixedly connected to the upper end of the support frame, and a rotating shaft is rotatably connected between each pair of mating mounting plates. A cam is fixedly connected to the outer wall of each of the two rotating shafts, and each of the two cams cooperates with a corresponding sliding plate.

[0006] Preferably, a first motor is mounted on the side wall of one of the mounting plates, the end of the output shaft of the first motor passing through one of the mounting plates and fixedly connected to one end of one of the rotating shafts.

[0007] Preferably, the other ends of both shafts pass through corresponding mounting plates and are fixedly connected to pulleys, with the two pulleys connected by belt drive.

[0008] Preferably, a plurality of connecting rods are fixedly connected to the inner wall of the dust collector body, and one end of the plurality of connecting rods is fixedly connected to a protective shell, and a second motor is installed inside the protective shell.

[0009] Preferably, the output shaft of the second motor passes through the protective shell and is fixedly connected to a connecting shaft. The lower end of the connecting shaft extends into the dust discharge pipe, and a spiral blade is fixedly connected to the outer wall of the connecting shaft.

[0010] Compared with the prior art, the advantages of this utility model are as follows: 1. The structure is designed with striking balls, springs, and cams. The cam drive and spring reset work together to make the striking balls reciprocate to strike the dust collector body. The vibration shakes off the dust particles adhering to the inner wall, preventing dust particles from accumulating, narrowing the airflow channel, weakening the dust removal effect, reducing the corrosion damage to the wall caused by long-term dust adhesion, and extending the service life of the equipment. 2. The system is equipped with a second motor, connecting shaft, and spiral blades. The second motor drives the spiral blades to rotate continuously inside the dust discharge pipe, pushing the accumulated dust particles and preventing them from clumping and clogging the pipe. This ensures that the dust discharge channel is unobstructed. At the same time, the spiral conveyor allows the dust particles to be discharged evenly and stably, further improving the overall operating efficiency of the dust removal system.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-5 A spiral electrostatic cyclone dust collector includes a dust collector body 1. An electrostatic field and a spiral channel are constructed inside the dust collector body 1, which is prior art and will not be described in detail here. A support frame 2 is fixedly connected to the outer wall of the dust collector body 1. The support frame 2 is U-shaped. An air outlet pipe 3 is fixedly connected to the upper end of the dust collector body 1. An air inlet pipe 4 is fixedly connected to the outer wall of the dust collector body 1. A dust discharge pipe 5 is fixedly connected to the lower end of the dust collector body 1. Two sliding grooves 6 are symmetrically opened at the upper end of the support frame 2. A sliding plate 7 is slidably connected to the bottom of each of the two sliding grooves 6. A moving rod 8 is fixedly connected to the opposite side of each of the two sliding plates 7. Two fixed plates 9 are fixedly connected to the upper end of the support frame 2. The opposite ends of each of the two moving rods 8 pass through the corresponding fixed plates 9 and are fixedly connected to a connecting plate 10. A striking ball 11 is embedded on the opposite side of each of the two connecting plates 10. The two striking balls 11 cooperate with the dust collector body 1. The outer walls of the two moving rods 8 are fitted with springs 12. The two ends of the two springs 12 are elastically connected to the side walls of the corresponding sliding plates 7 and the side walls of the fixed plates 9, respectively. The upper end of the support frame 2 is fixedly connected with four mounting plates 13. A rotating shaft 14 is rotatably connected between each pair of mating mounting plates 13. The outer walls of the two rotating shafts 14 are fixedly connected with cams 15. The two cams 15 are mating with the corresponding sliding plates 7. When the protruding end of the cam 15 pushes against the sliding plate 7, the moving rod 8 compresses the spring 12 and drives the connecting plate 10 to move, so that the striking ball 11 hits the outer wall of the dust collector body 1. When the protruding end of the cam 15 is disengaged, the spring 12 returns to its original position to achieve reciprocating striking. The vibration generated by the impact causes the dust particles adhering to the inner wall of the dust collector body 1 to fall off, avoiding the accumulation of dust particles and affecting the dust removal efficiency. A first motor 16 is installed on the side wall of one of the mounting plates 13. The first motor 16 is a servo motor. The end of the output shaft of the first motor 16 passes through one of the mounting plates 13 and is fixedly connected to one end of one of the rotating shafts 14. The other ends of the two rotating shafts 14 pass through the corresponding mounting plates 13 and are fixedly connected to pulleys 17. The two pulleys 17 are connected by a belt 18. Multiple connecting rods 19 are fixedly connected to the inner wall of the dust collector body 1. One end of the multiple connecting rods 19 is fixedly connected to a protective shell 20. The upper end of the protective shell 20 is a conical structure. A second motor 21 is installed inside the protective shell 20. The second motor 21 is a servo motor. The end of the output shaft of the second motor 21 passes through the protective shell 20 and is fixedly connected to a connecting shaft 22. The lower end of the connecting shaft 22 extends into the dust discharge pipe 5. Spiral blades 23 are fixedly connected to the outer wall of the connecting shaft 22. The second motor 21 drives the spiral blades 23 to rotate in the dust discharge pipe 5, continuously conveying the dust particles accumulated in the dust discharge pipe 5 downwards, preventing the dust particles from accumulating and clogging in the dust discharge pipe 5, and ensuring smooth dust discharge.

[0015] In this utility model, during the operation of the dust collector body 1, in order to prevent some dust particles from adhering to the inner wall of the dust collector body 1 due to stickiness or electrostatic adsorption, the first motor 16 can be started to drive one of the rotating shafts 14 to rotate. Through the transmission of the pulley 17 and the belt 18, the two rotating shafts 14 rotate synchronously, thereby driving the two cams 15 to rotate. When the protruding end of the cam 15 pushes against the sliding plate 7, the sliding plate 7 will slide in the sliding groove 6, thereby driving the moving rod 8 to move and compress the spring 12. At this time, the connecting plate 10 moves towards the dust collector body 1 until the striking ball 11 hits the outer wall of the dust collector body 1 to generate vibration, shaking off the dust particles adhering to the inner wall of the dust collector body 1. When the protruding end of the cam 15 disengages from the sliding plate 7, the sliding plate 7 returns to its original position under the elastic action of the spring 12, driving the moving rod 8, the connecting plate 10 and the striking ball 11 back to their initial positions, completing one striking cycle. As the cam 15 continues to rotate, the above process is repeated continuously, realizing the reciprocating impact of the striking ball 11 on the outer wall of the dust collector body 1, causing the attached dust particles to lose their adhesion under the vibration, fall off the inner wall and fall down into the dust discharge pipe 5. At the same time, the second motor 21 can be started to drive the connecting shaft 22 to rotate, which in turn causes the spiral blades 23 to rotate. At this time, the dust particles have accumulated in the dust discharge pipe 5. The rotating spiral blades 23 will continuously transport the dust particles in the dust discharge pipe 5 downward through the friction and thrust between the blade surface and the dust particles, so as to avoid agglomeration and blockage of the dust discharge pipe 5 and ensure that the dust discharge channel is unobstructed.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
