Description

Technical Field

[0001] This invention relates to the field of dust collector rapping technology, and more particularly to a rapping device for electrostatic precipitators. Background Technology

[0002] An electrostatic precipitator (ESP) is a device that removes particulate matter from the air using the principle of an electric field. It charges airborne particles through an electric field, then uses electrostatic adsorption or electric force to deposit them onto a collection plate, thus achieving air purification. ESPs are advantageous due to their stable operation and good dust removal efficiency. They are used in industries such as metallurgy and chemicals to purify gases or recover useful dust particles. The method involves using an electrostatic field to ionize the gas, causing dust particles to become charged and adhere to the electrodes. However, after prolonged use, a significant amount of dust accumulates on the electrode plates, typically requiring the use of a rapping device to remove the surface dust.

[0003] Existing methods for removing dust from the surface of electrostatic precipitators include manual periodic cleaning, which is cumbersome, wastes significant manpower, and is slow and inefficient. Other methods use rapping devices to remove dust from the electrode plates inside the precipitator; however, these devices are mostly installed on the electrode plate surface, limiting their effectiveness to a limited area while neglecting more distant areas. Therefore, there is an urgent need to address these issues. Summary of the Invention

[0004] Based on the technical problems existing in the background art, the present invention proposes a rapping device for electrostatic precipitators.

[0005] This invention proposes a vibrating device for an electrostatic precipitator, comprising a housing, vibrating rods, and a fixing frame. The housing contains a first connecting chamber and a second connecting chamber, with the second connecting chamber positioned on top of the first connecting chamber. Two first gears rotate within the first connecting chamber and mesh with each other. Two vibrating rods are provided, each sliding horizontally on one side of the housing surface. Connecting columns are fixedly connected to the surfaces of both vibrating rods, and sliding rods are fixedly connected to one end of each connecting column. Both sliding rods are horizontally positioned and fitted inside the housing. A first sliding mechanism for sliding the two sliding rods is provided inside the housing. The fixing frame is located on one side of the housing surface, and the housing slides on the surface of the fixing frame. A second sliding mechanism for sliding the housing is provided on the surface of the fixing frame. The two sliding rods allow the housing to slide up and down, and the springs inside the sliding rods allow them to be released, thus causing the vibrating rods to vibrate and improve the dust removal effect.

[0006] Preferably, the first sliding mechanism includes connecting rods, and two fixed plates are fixedly connected inside the first connecting chamber. Two connecting rods are provided, each fixedly connected to the surface of one of the two fixed plates. Both connecting rods are horizontally arranged and sleeved at the center of the interior of two sliding rods. Each sliding rod has a groove inside, and the two connecting rods are respectively sleeved inside the two grooves. A stop block is fixedly connected to one end of each connecting rod. A spring is sleeved inside each of the two grooves, and the two springs are respectively fixedly connected to one side of the surface of the two stop blocks to restrict the horizontal sliding of the two striking rods and the two sliding rods.

[0007] Furthermore, each of the two sliding rods is fixedly connected to a first rack on its opposite side. A first fixed shaft is sleeved at the center of each of the two first gears. Both first fixed shafts are vertically arranged, and their top ends are sleeved on the top of the first connecting compartment. A missing gear is sleeved on the surface of each of the two first fixed shafts. The two missing gears are located on the top of the two first gears and mesh with the two first racks respectively, so that the two missing gears and the two first racks can slide, thereby allowing the two sliding rods to slide into the housing. When the two missing gears are not meshing with the two first racks, the two sliding rods can slide out quickly.

[0008] Preferably, a second fixed shaft is fixedly connected to the top of one of the first fixed shafts. The second fixed shaft is sleeved inside the second connecting chamber. A worm gear rotates inside the second connecting chamber and is fixedly connected to the top of the second fixed shaft. A worm is inserted inside the outer shell and is sleeved inside the second connecting chamber. A rotating shaft is sleeved on the surface of the worm and cooperates with the worm gear. Two second gears rotate symmetrically on both sides of the outer shell surface. Each pair of second gears meshes with each other. Two second gears are fixedly connected to both ends of the worm, and the other two second gears are rotatably connected to the outer shell surface. Protective shells are fixedly connected to both sides of the outer shell surface, and two protective shells are sleeved on the surfaces of each pair of second gears. Second racks are fixedly connected to both sides of the fixed frame surface. Two second racks mesh with the other two second gears to drive the worm to rotate. Under the action of the worm gear and the meshing of the two first gears, the two missing gears rotate.

[0009] Furthermore, the second sliding mechanism includes two locking strips, each fixedly connected to one side of the outer shell surface. Each locking strip has a slot on its opposite side. Limiting rods are fixedly connected to opposite sides inside the fixing frame, and these limiting rods slide within their respective slots. A lead screw rotates inside the fixing frame, vertically positioned, with its bottom end rotatably connected to the bottom of the fixing frame. The top end of the fixing frame is fitted onto the top of the fixing frame. Fixing blocks are fixedly connected to both the upper and lower ends of one side of the outer shell surface, and both fixing blocks are fitted onto the lead screw surface. A mating block is fixedly connected to the outer shell surface, positioned between the two fixing blocks and fitted onto the lead screw surface, engaging with the lead screw. A reduction motor is mounted on the top of the fixing frame, with its output shaft fixedly connected to the top of the lead screw to drive its rotation. This, in conjunction with the mating block, allows the outer shell to slide up and down.

[0010] In this invention, the two sliding rods can slide while the outer casing is sliding up and down. At the same time, the springs inside the two sliding rods can release them, thereby causing the two striking rods to vibrate and improve the dust removal effect.

[0011] While the outer casing slides, the two striking rods vibrate the surface of the electrode plate, thereby increasing the vibrating range of the electrode plate surface and making it easier for dust to fall off, thus improving the effectiveness of the device. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-7 A vibrating device for an electrostatic precipitator includes a housing 1, striking rods 2, and a fixing frame 3. The housing 1 contains a first connecting chamber 11 and a second connecting chamber 12. The second connecting chamber 12 is located on top of the first connecting chamber 11. The first connecting chamber 11 contains two rotating first gears 52 that mesh with each other. Two striking rods 2 are provided, each sliding horizontally on one side of the surface of the housing 1. Connecting posts 21 are fixedly connected to the surfaces of both striking rods 2, and sliding rods 22 are fixedly connected to one end of each connecting post 21. Both sliding rods 22 are horizontally positioned. The two sliding rods 22 are both fitted inside the outer shell 1. The outer shell 1 is provided with a first sliding mechanism for sliding the two sliding rods 22. The fixing frame 3 is set on one side of the surface of the outer shell 1, and the outer shell 1 slides on the surface of the fixing frame 3. The surface of the fixing frame 3 is provided with a second sliding mechanism for sliding the outer shell 1. With the setting of the two sliding rods 22, the two sliding rods 22 can slide during the up and down sliding of the outer shell 1. At the same time, the setting of the spring 43 inside the two sliding rods 22 can cause the two sliding rods 22 to be ejected and released, thereby causing the two beating rods 2 to vibrate, thereby improving the dust removal effect.

[0022] Reference Figure 2 and Figure 4In a preferred embodiment, the first sliding mechanism includes a connecting rod 41. Two fixed plates 4 are fixedly connected inside the first connecting chamber 11. Two connecting rods 41 are provided, and the two connecting rods 41 are respectively fixedly connected to the surfaces of the two fixed plates 4. The two connecting rods 41 are both horizontally arranged. The two connecting rods 41 are respectively sleeved at the center of the interior of the two sliding rods 22. The interior of the two sliding rods 22 is provided with a sliding groove 24. The two connecting rods 41 are respectively sleeved inside the two sliding grooves 24. One end of the two connecting rods 41 is fixedly connected to a stop block 42. The interior of the two sliding grooves 24 is provided with a spring 43. The two springs 43 are respectively fixedly connected to one side of the surface of the two stop blocks 42 to limit the horizontal sliding of the two striking rods 2 and the two sliding rods 22.

[0023] Reference Figure 2 and Figure 3 In a preferred embodiment, each of the two sliding rods 22 is fixedly connected to a first rack 23 on one of their opposite sides. Each of the two first gears 52 has a first fixed shaft 51 sleeved at its center. Both first fixed shafts 51 are vertically arranged, and their top ends are sleeved on the top of the first connecting chamber 11. Each of the two first fixed shafts 51 has a missing gear 5 sleeved on its surface. Both missing gears 5 are located on the top of the two first gears 52. The two missing gears 5 mesh with the two first racks 23 respectively, so that the two missing gears 5 and the two first racks 23 can slide, thereby allowing the two sliding rods 22 to slide into the housing 1. When the two missing gears 5 are not meshing with the two first racks 23, the two sliding rods 22 can slide out quickly.

[0024] Reference Figure 3 , Figure 5 and Figure 6 In a preferred embodiment, a second fixed shaft 53 is fixedly connected to the top of a first fixed shaft 51. The second fixed shaft 53 is sleeved inside the second connecting chamber 12. A worm gear 54 rotates inside the second connecting chamber 12 and is fixedly connected to the top of the second fixed shaft 53. A worm 6 is inserted inside the outer shell 1 and sleeved inside the second connecting chamber 12. A rotating shaft 61 is sleeved on the surface of the worm 6 and engages with the worm gear 54. Two second gears 62 rotate symmetrically on both sides of the outer shell 1, and each pair of second gears 62 meshes with each other. The worm gear 6 is fixedly connected to both ends of the worm 6, and the other two second gears 62 are rotatably connected to the surface of the outer shell 1. Protective shells 17 are fixedly connected to both sides of the surface of the outer shell 1. The two protective shells 17 are respectively fitted onto the surface of each pair of second gears 62. The two sides of the surface of the fixing frame 3 are fixedly connected to the second racks 31. The two second racks 31 mesh with the other two second gears 62 respectively to drive the worm 6 to rotate. Under the action of the worm wheel 54 and the meshing of the two first gears 52, the two missing gears 5 rotate.

[0025] Reference Figure 6 and Figure 7 In a preferred embodiment, the second sliding mechanism includes two locking strips 13, which are respectively fixedly connected to one side of the surface of the outer shell 1. Each locking strip 13 has a slot 14 on its opposite side. Limiting rods 32 are fixedly connected to opposite sides inside the fixing frame 3, and the two limiting rods 32 slide within the two slots 14. A lead screw 7 rotates inside the fixing frame 3, and the lead screw 7 is vertically arranged. The bottom end of the lead screw 7 is rotatably connected to the bottom of the fixing frame 3, and the top end of the fixing frame 3 is fitted onto the top of the fixing frame 3. The outer casing 1 has two fixed blocks 15 fixedly connected to the upper and lower ends of one side of its surface. Both fixed blocks 15 are sleeved on the surface of the lead screw 7. A mating block 16 is fixedly connected to the surface of the outer casing 1. The mating block 16 is located between the two fixed blocks 15 and is sleeved on the surface of the lead screw 7. The mating block 16 and the lead screw 7 are mated. A reduction motor 71 is installed on the top of the fixing frame 3. The output shaft of the reduction motor 71 is fixedly connected to the top of the lead screw 7 and is used to drive the lead screw 7 to rotate. Thus, with the cooperation of the mating block 16, the outer casing 1 can slide up and down.

[0026] In this invention, the two sliding rods 22 slide during the up-and-down sliding of the outer casing 1. Simultaneously, the springs 43 inside the two sliding rods 22 allow them to be ejected, causing the two striking rods 2 to vibrate and improve dust removal efficiency. In use, the fixing bracket 3 must first be installed in a suitable position so that the surface of the outer casing 1 is close to the electrode plate to be struck. Then, the drive reduction motor 71 drives the lead screw 7 to rotate. With the cooperation of the mating block 16, the outer casing 1 slides up and down. As the outer casing 1 slides downwards, the four second gears 62 rotate under the connection of the two second racks 31, simultaneously driving the worm gear 6 and the rotating shaft 61 to rotate. With the cooperation of the worm wheel 54, the second fixed shaft 53 and the first fixed shaft 51... The device rotates, and with the meshing of the two first gears 52, the two first gears 52 rotate simultaneously, allowing the two missing gears 5 to rotate at the same time. When the two missing gears 5 rotate simultaneously, they drive the two first racks 23 to slide, thereby driving the two slide rods 22 to slide into the outer casing 1. At this time, under the restriction of the connecting rod 41 and the stop block 42, the two springs 43 will be compressed. When the two missing gears 5 are no longer meshing with the two first racks 23, the elasticity of the two springs 43 will release the two first racks 23 and the two slide rods 22. The two slide rods 22 will drive the two striking rods 2 to vibrate the surface of the electrode plate, making it easier for dust on the substrate surface to fall off. At the same time, during the sliding of the outer casing 1, the vibration range of the substrate surface can be increased, thereby improving the effectiveness of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
