Technical Field
[0001] The invention belongs to the technical field of electrostatic precipitators, and in particular relates to a vibration and dust cleaning device for an electrostatic precipitator. Background Art
[0002] Electrostatic precipitators are commonly used in thermal power plants. Their function is to remove particulate dust from boiler flue gas, thereby reducing emission pollution and improving air quality. Their working principle is to form a strong electric field through the cathode, which makes the dust in the airflow carry a negative charge, and then through the principle of opposite charges attracting each other, the dust is adsorbed on the anode surface. After working for a period of time, the dust accumulated on the anode surface will affect the adsorption efficiency and needs to be cleaned in time.
[0003] However, the existing cleaning device has a fixed vibration position, which causes the dust far away from the vibration point to be less susceptible to force and difficult to fall off, resulting in poor cleaning effect. In addition, the dust generated during vibration is easily carried away by the flue gas again. Summary of the Invention
[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a vibration and dust cleaning device for an electrostatic precipitator.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions:
[0006] The outer wall of the motor is provided with a toothed plate, and the toothed plate is fixed with a toothed plate so as to be close to the toothed plate and slided on the toothed plate.

[0008] In the above-mentioned vibration cleaning device for an electrostatic precipitator, an abutment column is welded on the outer wall of one end of the slider close to the filter plate, and a fixing frame is welded on the inner wall of the outer shell between the filter plate and the turntable. A plurality of circumferentially distributed grooves of different specifications are provided on the inner ring wall of the fixing frame, and the abutment column is adapted to the groove.
[0009] In the above-mentioned vibration and dust cleaning device for an electrostatic precipitator, a brush is welded on the end wall of the abutment column, and the brush is adapted to the filter plate.
[0010] In the above-mentioned vibration and cleaning device for an electrostatic precipitator, the trigger mechanism includes a slider 2, a slider 2 is inserted into the outer wall of the bracket for sliding in the horizontal direction, a spring 4 is welded between the outer wall of the slider 2 and the outer wall of the bracket, and a rope is fixed between the outer wall of the anode plate and the outer wall of the slider 2.
[0011] In the above-mentioned vibration and cleaning device for an electrostatic precipitator, electric contact piece 2 is fixed on the outer wall of the slider 2, and electric contact piece 1 is fixed on the inner wall of the outer shell away from the filter plate. Electric contact piece 1 is adapted to electric contact piece 2, and both electric contact piece 1 and electric contact piece 2 are connected to the circuit of the motor. A sliding rod is welded on the bottom outer wall of the anode plate, and the sliding rod is slidably inserted into the outer wall of the bracket.
[0012] In the above-mentioned vibration and dust cleaning device for an electrostatic precipitator, a spring 1 is welded between the outer wall of the anode plate and the outer wall of the bracket, and the spring 1 is sleeved on the outer wall of the slide rod.
[0013] In the above-mentioned vibration and dust cleaning device for an electrostatic precipitator, a hook is welded on the bottom outer wall of the slide rod, and oblique teeth are welded on the bottom outer wall of the second slider, and the oblique teeth are adapted to the hook.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Multi-point vibration: through the provided turntable, slider 1 and fixed frame, the turntable drives the knocking rod and the brush on the slider 1 to slide back and forth under the cooperation of the inclined block 1 and the inclined block 2, so that the knocking rod can continuously hit the anode plate to achieve the effect of vibration and cleaning, and the dust falls into the cleaning hopper below and is collected. In addition, the turntable drives the slider 1 to rotate during the reciprocating sliding process. Under the cooperation of the abutment column and the groove, the slider 1 and the knocking rod are radially floated, so that the knocking rod can float radially while vibrating in the circumference, thereby making the vibration points more dispersed, thereby avoiding the situation where the vibration position is fixed, resulting in the dust far away from the vibration point not being easy to fall off;
[0016] 2. Anti-dust: The filter plate is set up so that the dust generated during the cleaning process will be intercepted in the shell after being filtered by the filter plate, preventing the dust from being carried away by the flue gas. When the brush contacts the filter plate, it can brush off the dust accumulated on the filter plate and make it fall into the cleaning hopper, while preventing the filter plate from being blocked.
[0017] 3. Self-detection: Through the trigger mechanism, when the weight of the accumulated dust is sufficient to drive the anode plate to push the hook to disengage from the bevel teeth, under the action of spring four, slider two drives electric contact piece two to abut against electric contact piece one, so that the motor is energized to vibrate and clean the dust. As the dust on the anode plate falls off, spring one pushes the anode plate up and reset again. The anode plate is pulled to the side close to the anode plate by the rope, so that electric contact piece two is disconnected from electric contact piece one, and the motor is turned off, achieving the effect of automatic cleaning when the dust accumulates to a certain extent.

The anode plate 15 is slidably inserted on the outer wall of the bracket 131, and the knocking rod 32 is adapted to the anode plate 15. A trigger mechanism is provided in the shell 1, and an air outlet 12 is provided on the outer wall of the end of the shell 1 close to the filter plate 14, and an air inlet 11 and a ash cleaning hopper 13 distributed up and down are welded on the outer wall of the end of the shell 1 away from the filter plate 14. An abutment column 33 is welded on the outer wall of the end of the slider 3 close to the filter plate 14, and a fixing frame 17 is welded on the inner wall of the shell 1 between the filter plate 14 and the turntable 21. A plurality of circumferentially distributed grooves 171 of different specifications are provided on the inner ring wall of the fixing frame 17. The abutment column 33 is adapted to the groove 171, and a brush 34 is welded on the end wall of the abutment column 33, and the brush 34 is adapted to the filter plate 14.
[0031] A turntable 21 is slidably sleeved on the main shaft end wall of the motor 2 through a keyway, so that the turntable 21 can rotate with the main shaft of the motor 2 and slide along its axial direction at the same time. Under the action of the second spring 23, the inclined block 142 and the second inclined block 22 always maintain an abutment state. When the inclined block 142 and the second inclined block 22 are engaged, the turntable 21 drives the brush 34 to abut against the filter plate 14. When the inclined block 142 and the second inclined block 22 are staggered, the turntable 21 drives the knocking rod 32 to abut against the anode plate 15. Under the action of the third spring 31, the abutment column 33 always maintains an abutment state with the groove 171.
[0032] The above content is further elaborated: during operation, the flue gas is input into the outer shell 1 from the air inlet 11, and the negatively charged dust in the flue gas will be adsorbed and accumulated on the anode plate 15. Then the flue gas is further filtered by the filter plate 14 and discharged through the air outlet 12. When the weight of the dust accumulated on the anode plate 15 reaches the starting condition of the trigger mechanism, the trigger mechanism starts and energizes the motor 2, so that the motor 2 drives the turntable 21 to rotate. Under the cooperation of the inclined block 142 and the inclined block 22, the turntable 21 slides back and forth horizontally along the main shaft of the motor 2, so that the turntable 21 drives the knocking rod 32 and the brush 34 on the slider 3 to slide back and forth, so that the knocking rod 32 can continuously hit the anode plate 15, thereby achieving the effect of vibrating and cleaning, and the dust falls. The dust collected by the brush 34 will be collected in the ash hopper 13 below, and the dust generated during the cleaning process will still be intercepted in the outer shell 1 after being filtered by the filter plate 14, so as to prevent the dust from being carried away by the flue gas. When the brush 34 abuts against the filter plate 14, the dust accumulated on the filter plate 14 can be brushed off and fall into the ash hopper 13, thereby preventing the filter plate 14 from being blocked. In addition, the turntable 21 drives the slider 3 to rotate during the reciprocating sliding process. Under the cooperation of the abutting column 33 and the groove 171, the slider 3 is radially floated with the knocking rod 32, so that the knocking rod 32 can float radially while being vibrated in the circle, thereby making the vibration points more dispersed, thereby avoiding the situation where the vibration position is fixed, resulting in the dust far away from the vibration point not being easy to fall off.
[0033] Specifically, the trigger mechanism includes a slider 24, a slider 24 is inserted into the outer wall of the bracket 131 in a horizontal sliding direction, a spring 41 is welded between the outer wall of the slider 24 and the outer wall of the bracket 131, a rope 44 is fixed between the outer wall of the anode plate 15 and the outer wall of the slider 24, an electric contact 2 43 is fixed on the outer wall of the slider 24, an electric contact 16 is fixed on the inner wall of the housing 1 away from the filter plate 14, the electric contact 16 is adapted to the electric contact 2 43, and the electric contact 16 is adapted to the electric contact 16. The electric contact piece 2 43 is connected to the circuit of the motor 2. A slide bar 151 is welded on the bottom outer wall of the anode plate 15. The slide bar 151 is slidably inserted into the outer wall of the bracket 131. A spring 152 is welded between the outer wall of the anode plate 15 and the outer wall of the bracket 131. The spring 152 is mounted on the outer wall of the slide bar 151. A hook 153 is welded on the bottom outer wall of the slide bar 151. A bevel tooth 42 is welded on the bottom outer wall of the slider 2 4. The bevel tooth 42 is adapted to the hook 153.
[0034] In the initial state, spring 152 pushes the anode plate 15 upward, and the anode plate 15 pulls the slider 2 4 through the rope 44 to compress the spring 41, causing it to move toward the side close to the anode plate 15. At this time, the hook 153 undergoes elastic deformation and abuts against the bevel tooth 42, so that the hook 153 can limit the slider 2 4.
[0035] The above content is further elaborated: during operation, as the weight of dust accumulated on the anode plate 15 increases, the anode plate 15 gradually overcomes the elastic force of the spring 152 and moves downward, the anode plate 15 drives the slide bar 151 to move downward, and the slide bar 151 drives the hook 153 to move downward. Since the hook 153 is elastically bent at the beginning, the hook 153 can always abut against the bevel tooth 42 before the deformation is restored. When the accumulated dust weight is sufficient to drive the anode plate 15 to push the hook 153 to disengage from the bevel tooth 42, at this time, under the action of the spring four 41, the slider 2 4 drives the electric contact piece 2 43 to abut against the electric contact piece 1 16, so that the motor 2 is energized to vibrate and clean the dust, so as to achieve the effect of automatic cleaning when the dust accumulates to a certain extent. As the dust on the anode plate 15 falls off, the spring 152 pushes the anode plate 15 up and reset again, and the anode plate 15 is pulled to the side close to the anode plate 15 by the rope 44, so that the electric contact piece 2 43 is disconnected from the electric contact piece 1 16, and the motor 2 is turned off.
[0036] The working principle and use process of the present invention are as follows: when working, the smoke is input into the housing 1 from the air inlet 11, and the negatively charged dust in the smoke will be adsorbed and accumulated on the anode plate 15. Then the smoke is further filtered by the filter plate 14 and discharged through the air outlet 12. As the weight of the dust accumulated on the anode plate 15 increases, the anode plate 15 gradually overcomes the elastic force of the spring 152 and moves downward. The anode plate 15 drives the slide bar 151 to move downward, and the slide bar 151 drives the hook 153 to move downward. Since the hook 153 is elastically bent at the beginning, the hook 153 can start to move downward before the deformation is restored. Finally, it abuts against the bevel teeth 42. When the accumulated dust weight is sufficient to drive the anode plate 15 to push the hook 153 to disengage from the bevel teeth 42, at this time, under the action of the spring four 41, the slider two 4 drives the electric contact piece two 43 to abut against the electric contact piece one 16, so that the motor 2 is energized to vibrate and clean the dust, so as to achieve the effect of automatic dust cleaning when the dust accumulates to a certain extent. The motor 2 drives the turntable 21 to rotate. Under the cooperation of the bevel block one 142 and the bevel block two 22, the turntable 21 slides back and forth horizontally along the main shaft of the motor 2, so that the turntable 21 drives the knocking rod 3 on the slider one 3. 2 and the brush 34 slide back and forth, so that the knocking rod 32 can continuously hit the anode plate 15, achieving the effect of vibration cleaning, and the dust falls into the cleaning hopper 13 below for collection, and the dust generated during the cleaning process will still be intercepted in the shell 1 after being filtered by the filter plate 14, avoiding the dust being carried away by the flue gas. When the brush 34 abuts against the filter plate 14, the dust accumulated on the filter plate 14 can be brushed off and fall into the cleaning hopper 13, while avoiding the clogging of the filter plate 14. In addition, the slider 3 is driven to rotate in the process of reciprocating sliding of the turntable 21, and the slider 3 is abutted against the column 33. With the cooperation of the groove 171, the slider 13 and the knocking rod 32 float radially, so that the knocking rod 32 floats radially while vibrating in the circumference, thereby making the vibration points more dispersed, thereby avoiding the vibration position being fixed, resulting in the dust far away from the vibration point not being easy to fall off. As the dust on the anode plate 15 falls off, the spring 152 pushes the anode plate 15 up and reset again, and the anode plate 15 is pulled to the side close to the anode plate 15 by the rope 44, so that the electric contact piece 2 43 is disconnected from the electric contact piece 16, and the motor 2 is turned off.
