Description

[0002] The electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate dust from the flue gas discharged by coal-fired or oil-fired boilers. The cathode system is the main component for establishing the electric field in the electrostatic precipitator, which determines the strength of the discharge and directly affects the dust charge and driving effect in the gas. If the cathode wire in the cathode system is not cleaned in time, it may be seriously ash-coated and cannot produce normal corona. The corona current will decrease, which will affect the charge of the dust and reduce the dust removal efficiency. The cleaning of the cathode system is generally achieved by mechanical vibration.

[0003] When the top of the cathode of the electrostatic precipitator is vibrated for dust removal, the traditional method is to use a driving device to drive a hammer to hit the top of the cathode of the electrostatic precipitator. Only one direction can be struck at one time, and the range of the strike is limited, resulting in the effect of the strike not being very obvious. Therefore, a hammer vibrating dust removal device for the top of the cathode of the electrostatic precipitator is proposed. Utility Model Content

[0022] Specifically, the telescopic assembly includes a mounting groove 8 provided on the top side of the electrostatic precipitator body 1, a telescopic cylinder 9 is fixedly mounted on the inner wall of the bottom side of the mounting groove 8, and the output end of the telescopic cylinder 9 is fixedly connected to the bottom side of the driving block 10. When it is necessary to knock and remove dust, the telescopic cylinder 9 on the telescopic assembly is started to run, and the driving block 10 will move downward, and at this time, the downward pressure regulating block 12 is driven to move downward;

[0023] Specifically, the downward movement drives the rotating assembly to include a downward pressure regulating block 12 rotatably mounted on the inner wall of the side groove 11, one side of the downward pressure regulating block 12 extends to the outside of the side groove 11 and is adapted to the rotating pressure block 17, one end of the extrusion spring 13 is fixedly mounted on the bottom side of the downward pressure regulating block 12, the other end of the extrusion spring 13 is fixedly mounted on the inner wall of one side of the side groove 11, a horizontal pad 14 is fixedly mounted on the top inner wall of the side groove 11, the bottom side of the horizontal pad 14 is in contact with the top side of the downward pressure regulating block 12, a downward pressure horizontal surface 15 is provided on the bottom side of the downward pressure regulating block 12, and the rotating A movable horizontal plane 19 is provided on the top side of the pressure block 17, and the downward pressure horizontal plane 15 is adapted to the movable horizontal plane 19. When the downward pressure adjustment block 12 moves downward, it will contact the rotating pressure block 17. The downward pressure horizontal plane 15 and the movable horizontal plane 19 can drive the rotating pressure block 17 to rotate when they move downward. Since there is a certain gap between the rotating pressure block 17 and the driving block 10, the rotating pressure block 17 will not touch the driving block 10 when it rotates. As the driving block 10 continues to move downward, the rotating pendulum 4 will rotate. At this time, the hammer striking block 5 will be tilted upward under the action of the lever principle.

[0024] Specifically, the reset assembly includes a connecting block 6 fixedly mounted on one side of the top upright 3, one end of a tension spring 7 is fixedly mounted on one side of the connecting block 6, and the other end of the tension spring 7 is fixedly mounted on one side of a rotating swing rod 4. Two rotating swing rods 4 are rotatably mounted on the top side of the electrostatic precipitator body 1. The two rotating swing rods 4 are pulled by the tension spring 7 on the reset spring so that the hammer striking block 5 contacts the top side of the electrostatic precipitator body 1. When the rotating swing rod 4 moves, the tension spring 7 will be pulled. After the downward pressure regulating block 12 continues to move downward, the downward pressure regulating block 12 will be misaligned with the rotating pressing block 17. At this time, under the elastic force of the tension spring 7, the rotating swing rod 4 is driven to rotate and reset. At this time, under the action of the elastic force, the hammer striking blocks 5 on both sides can quickly strike the top of the cathode of the electrostatic precipitator body 1, thereby realizing the effect of vibration dust removal. By moving downward once, vibration striking in two directions can be achieved, and the striking range is wide.

[0025] Specifically, the top side of the downward pressure regulating block 12 is provided with an upwardly moving arc surface 16, and the bottom side of the rotating pressure block 17 is provided with a bottom arc surface 18, and the bottom arc surface 18 is adapted to the upwardly moving arc surface 16.

After moving upward, it can move downward again, driving the rotating swing rod 4 to rotate, so as to realize the knocking dust removal.

[0026] When in use: when the top of the cathode of the electrostatic precipitator body 1 is knocked for dust removal, two rotating swing rods 4 are rotatably installed on the top side of the electrostatic precipitator body 1. The two rotating swing rods 4 are pulled by the tension spring 7 on the reset spring to make the hammer knocking block 5 contact with the top side of the electrostatic precipitator body 1. When it is necessary to knock for dust removal, the telescopic cylinder 9 on the telescopic assembly is started to operate, and the driving block 10 will move downward, and at this time, the downward pressure regulating block 12 will move downward. When the downward pressure regulating block 12 moves downward, it will contact the rotating pressing block 17. The downward pressure horizontal plane 15 and the moving horizontal plane 19 are in contact with each other. When they move downward, they can drive the rotating pressure block 17 to rotate. Since there is a certain gap between the rotating pressure block 17 and the driving block 10, the rotating pressure block 17 will not touch the driving block 10 when it rotates. As the driving block 10 continues to move downward, the rotating swing rod 4 will rotate. At this time, the hammer striking block 5 will be tilted upward under the action of the lever principle. When the rotating swing rod 4 moves, it will pull the tension spring 7. After the downward pressure adjusting block 12 continues to move downward, the downward pressure The adjusting block 12 will be misaligned with the rotating pressing block 17. At this time, under the elastic force of the tension spring 7, the rotating swing rod 4 is driven to rotate and reset. At this time, under the action of the elastic force, the hammer striking blocks 5 on both sides can quickly strike the cathode of the electrostatic precipitator body 1, thereby achieving the effect of vibration dust removal. By moving downward once, vibration striking in two directions can be achieved, and the striking range is wide. In this scheme, rotating pressing blocks 17 in more directions can be set, so that when the driving block 10 moves downward, it can drive multiple hammer striking blocks 5 to strike Above the electrostatic precipitator body 1, the knocking effect is better. This scheme shows two hammers knocking blocks 5. After the telescopic cylinder 9 moves down and returns to its position, the downward pressure adjusting block 12 will contact the rotating pressure block 17. The upward curved surface 16 and the bottom curved surface 18 are set. Under the extrusion of the curved surface, the downward pressure adjusting block 12 will rotate and be received in the side groove 11, so as not to block the upward movement of the driving block 10. After moving up, it can move down again to drive the rotating rocker arm 4 to rotate, thereby realizing knocking dust removal, which is easy to use.
