However, it is difficult to clean the dust removal device during the dust removal process, which easily causes excessive dust accumulation, resulting in a weakened subsequent dust removal effect and incomplete dust cleaning. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high - efficiency electrostatic dust removal device with a uniform flow structure, which solves the problems raised in the above - mentioned background technique.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A high - efficiency electrostatic dust removal device with a uniform flow structure includes a box body. A support frame is fixedly installed at the bottom of the box body. An air inlet pipe is fixedly installed at the bottom of the box body. An air outlet pipe is fixedly installed on the left side of the box body. A discharge pipe is arranged at the bottom of the box body. A cleaning device is arranged inside the box body.

[0007] Among them, the cleaning device includes a first motor, a reciprocating lead screw, a sleeve, a slide plate, a discharge plate, a fixed rod, and a first scraping rod. The first motor is fixedly installed on the left side of the box body. The reciprocating lead screw is fixedly installed at the output end of the first motor. The sleeve is slidably installed on the surface of the reciprocating lead screw. The slide plate is fixedly installed on the circumferential surface of the sleeve. The discharge plate is fixedly installed on the inner wall of the box body. The fixed rod is fixedly installed on the top of the slide plate. The first scraping rod is fixedly installed on the top of the fixed rod. The first motor drives the reciprocating lead screw to start rotating. The rotation of the reciprocating lead screw drives the sleeve to start moving. The movement of the sleeve drives the slide plate to start moving. The movement of the slide plate drives the fixed rod to start moving. The movement of the fixed rod drives the first scraping rod to start moving. The movement of the first scraping rod cleans the dust on the discharge plate;

[0008] Among them, a collection device for collecting dust and a pushing device for accelerating gas flow are arranged inside the box body. By setting the collection device, it is ensured that the dust can be centrally collected. By setting the pushing device, the residence time of the gas in the device is reduced.

[0009] According to the above technical solution, the cleaning device further includes a first elastic telescopic rod, a convex block, and a convex plate. The first elastic telescopic rod is fixedly installed on the circumferential surface of the fixed rod. The convex block is fixedly installed at the movable end of the first elastic telescopic rod. The convex plate is fixedly installed at the bottom of the discharge plate. The first scraping rod contacts the discharge plate. The surfaces of the convex block and the convex plate that are in contact with each other are both set as arc surfaces. By the contact, it is ensured that the first scraping rod can clean the discharge plate when moving. By setting the arc surfaces, it is ensured that the convex block can be pushed in the reverse direction when the convex block and the convex plate are in contact.

[0010] According to the above technical solution, the collection device includes a second elastic telescopic rod, a second scraping rod, an inclined plane block, a partition net, and a push rod. The second elastic telescopic rod is fixedly installed on the inner wall of the box body. The second scraping rod is fixedly installed at the movable end of the second elastic telescopic rod. The inclined plane block is fixedly installed on the top of the second scraping rod. The partition net is fixedly installed between the box body and the air outlet pipe. The push rod is fixedly installed at the bottom of the sleeve. While the sleeve moves, it drives the push rod to start moving. The movement of the push rod contacts and pushes the inclined plane block to start moving downward. The movement of the inclined plane block drives the second scraping rod to start moving downward. The movement of the second scraping rod contacts and cleans the partition net.

[0011] According to the above technical solution, the collection device further includes a flap, a fixed block, a sliding rod, and a poking rod. The flap is rotatably installed on the inner wall of the box body. The fixed block is fixedly installed on the inner wall of the box body. The sliding rod is rotatably installed on the top of the flap. The poking rod is rotatably installed on the bottom of the flap. While the second scraping rod moves downward, it contacts and pushes the sliding rod to start moving downward. The movement of the sliding rod drives the flap to start rotating. The rotation of the flap opens the discharge port between the box body and the discharge pipe. After the second scraping rod no longer pushes the sliding rod, the sliding rod starts to move back under the action of the first spring. The movement of the sliding rod drives the flap to start rotating. The rotation of the flap closes the discharge port between the box body and the discharge pipe.

[0012] According to the above technical solution, the second scraping rod contacts the separation net. The surfaces of the push rod and the inclined plane block that contact each other are both set as inclined planes. A first spring is arranged between the sliding rod and the inner wall of the box body. By means of the contact, it is ensured that the second scraping rod can clean the separation net when moving. By setting the inclined plane, it is ensured that the push rod can smoothly push the inclined plane block when moving. By setting the first spring, it is ensured that the sliding rod can achieve self-reset.

[0013] According to the above technical solution, the pushing device includes a fixing plate, a second motor, a rotating shaft and a fan blade. The fixing plate is fixedly installed on the inner wall of the air outlet pipe. The second motor is fixedly installed on the right side of the fixing plate. The rotating shaft is fixedly installed at the output end of the second motor. The fan blade is fixedly installed on the circumferential surface of the rotating shaft. After the gas is cleaned by passing through the discharge plate and then passes through the air outlet pipe and continuously moves to the next processing link, at this time, the staff starts the second motor, so that the second motor drives the rotating shaft to start rotating. The rotation of the rotating shaft drives the fan blade to start rotating, and the rotation of the fan blade accelerates the gas flow rate inside the air outlet pipe.

[0014] According to the above technical solution, the pushing device further includes a fixing box, a filter plate, a third elastic telescopic rod, a pull ring, an L-shaped rod, an inclined plane rod and a clamping plate.

The L-shaped rod is fixedly installed on the back of the pull ring. The inclined plane rod is slidably installed at the front of the filter plate. The clamping plate is fixedly installed at the front of the fixing box. By the staff holding the handle of the filter plate and pulling the pull ring, the pull ring starts to move under the pulling of the staff and drives the L-shaped rod to start moving. The movement of the L-shaped rod disengages from the contact with the inclined plane rod. Subsequently, the inclined plane rod starts to move and reset under the action of the second spring. The movement of the inclined plane rod disengages from the contact with the clamping plate and releases the restriction on the filter plate.

[0015] According to the above technical solution, the surfaces of the L-shaped rod and the inclined plane rod that contact each other are both set as inclined planes. A second spring is arranged between the inclined plane rod and the filter plate. By setting the inclined plane, it is ensured that the L-shaped rod can smoothly push the inclined plane rod when moving. By setting the second spring, it is ensured that the inclined plane rod can achieve self-reset.

[0016] The present invention provides an efficient electrostatic dust removal device with a uniform flow structure, having the following beneficial effects:

[0017] (1) In this invention, the dust on the discharge plate is cleaned by the movement of the first scraping rod, preventing excessive dust accumulation, ensuring the stability of the electric field intensity of the discharge plate, thereby improving the dust removal efficiency. At the same time, it reduces the damage of dust to the discharge plate and extends the service life of the equipment. By the vibration of the convex plate, the discharge plate vibrates together, which can loosen and shed the dust adsorbed on the discharge plate, thus improving the dust cleaning efficiency, ensuring the cleanliness of the discharge plate, avoiding the electric field fluctuation caused by dust accumulation, and improving the stability of the entire electrostatic dust removal system. At the same time, by improving the dust cleaning efficiency, reducing energy consumption, and lowering maintenance costs, the vibration cleaning can improve the economic benefits of the electrostatic dust removal device.

[0018] (2) In this invention, the second scraping rod moves to contact and clean the partition net, ensuring the smoothness of the air outlet, improving the gas flow efficiency, reducing the resistance of gas flow, and reducing the energy consumption of the fan, thereby reducing the operating cost. At the same time, it reduces the corrosion and wear of the partition net by dust and extends the service life of the equipment. When the collection port is opened, the dust adsorbed on the discharge plate can be centrally collected, ensuring that the dust is completely removed, thus improving the dust removal efficiency. When the collection port is closed, it can prevent the dust from re-entering the air flow and prevent secondary dust generation, ensuring the dust removal effect.

[0019] (3) In this invention, the rotation of the fan blade accelerates the gas flow velocity inside the air outlet pipe, which can quickly discharge the purified gas from the device, reduce the residence time of the gas in the device, improve the overall treatment efficiency, and at the same time prevent the purified gas from flowing back into the dust removal device, avoiding secondary pollution or abnormal equipment operation.

[0020] (4) In this invention, the inclined plane rod moves to contact the clamping plate and restrict the filter plate, so that the filter plate will not displace during operation, ensuring uniform air flow through the filter plate, enabling the dust to fully contact the filter plate and be captured, thereby improving the dust removal efficiency. At the same time, restricting the movement of the filter plate can reduce the friction between the filter plate and other components, reduce the wear of the filter plate, and extend its service life.

Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 8 , an embodiment of the present invention is: an efficient electrostatic dust removal device with a uniform flow structure, including a box body 1, a support frame 2 fixedly installed at the bottom of the box body 1, an intake pipe 3 fixedly installed at the bottom of the box body 1, an exhaust pipe 4 fixedly installed on the left side of the box body 1, a discharge pipe 5 arranged at the bottom of the box body 1, and a cleaning device arranged inside the box body 1;

[0032] Among them, the cleaning device includes a first motor 6, a reciprocating lead screw 7, a sleeve 8, a slide plate 9, a discharge plate 10, a fixed rod 11 and a first scraping rod 12. The first motor 6 is fixedly installed on the left side of the box body 1, the reciprocating lead screw 7 is fixedly installed at the output end of the first motor 6, the sleeve 8 is slidably installed on the surface of the reciprocating lead screw 7, the slide plate 9 is fixedly installed on the circumferential surface of the sleeve 8, the discharge plate 10 is fixedly installed on the inner wall of the box body 1, the fixed rod 11 is fixedly installed on the top of the slide plate 9, and the first scraping rod 12 is fixedly installed on the top of the fixed rod 11. The dust on the discharge plate 10 is cleaned by the movement of the first scraping rod 12, preventing excessive dust accumulation, ensuring the stable electric field intensity of the discharge plate 10, thereby improving the dust removal efficiency, reducing the damage of dust to the discharge plate 10, and prolonging the service life of the equipment.

[0033] The cleaning device further includes a first elastic telescopic rod 13, a convex block 14 and a convex plate 15. The first elastic telescopic rod 13 is fixedly installed on the circumferential surface of the fixed rod 11, the convex block 14 is fixedly installed at the movable end of the first elastic telescopic rod 13, the convex plate 15 is fixedly installed at the bottom of the discharge plate 10, the first scraping rod 12 is in contact with the discharge plate 10, and the surfaces of the convex block 14 and the convex plate 15 in contact with each other are both set as arc surfaces. It is ensured that the first scraping rod 12 can clean the discharge plate 10 during movement through the contact, and it is ensured that the convex block 14 can be pushed in the reverse direction when the convex block 14 is in contact with the convex plate 15 by setting the arc surface.

[0034] During the operation of this embodiment: First, before starting the work, the staff checks the working state of the device. After the staff confirms that the inspection is correct and there are no other problems with the device, the gas to be dust-removed is introduced into the interior of the box body 1 through the air inlet pipe 3. After the gas enters the interior of the box body 1, it comes into full contact with the discharge plate 10. The discharge plate 10 adsorbs dust and other particles, and the gas then enters the next treatment link through the discharge area. After the gas to be dust-removed is introduced into the interior of the box body 1, the staff starts the first motor 6, so that the first motor 6 drives the reciprocating screw rod 7 to start rotating. The rotation of the reciprocating screw rod 7 drives the sleeve 8 to start moving. The movement of the sleeve 8 drives the sliding plate 9 to start moving. The movement of the sliding plate 9 drives the fixed rod 11 to start moving. The movement of the fixed rod 11 drives the first scraping rod 12 to start moving. The first scraping rod 12 moves to clean the dust on the discharge plate 10, preventing excessive dust accumulation, ensuring the stability of the electric field intensity of the discharge plate 10, thereby improving the dust removal efficiency, reducing the damage of dust to the discharge plate 10 at the same time, and prolonging the service life of the equipment. While the fixed rod 11 is moving, it drives the first elastic telescopic rod 13 to start moving. The movement of the first elastic telescopic rod 13 drives the convex block 14 to start moving. The convex block 14 moves and contacts the convex plate 15. Subsequently, under continuous movement, the convex block 14 reversely pushes the first elastic telescopic rod 13, and the movable end of the first elastic telescopic rod 13 is compressed. When the convex block 14 continues to move, it disengages from the convex plate 15. Subsequently, the convex block 14 starts to move and reset under the action of the movable end of the first elastic telescopic rod 13. The convex block 14 moves and resets to contact and knock the convex plate 15 to make it vibrate. The vibration of the convex plate 15 causes the discharge plate 10 to vibrate together, which can loosen and fall off the dust adsorbed on the discharge plate 10, thereby improving the dust cleaning efficiency, ensuring the cleanliness of the discharge plate 10, avoiding the electric field fluctuation caused by dust accumulation, and improving the stability of the entire electrostatic dust removal system. At the same time, by improving the dust cleaning efficiency, reducing energy consumption, and lowering the maintenance cost, the vibration cleaning can improve the economic benefits of the electrostatic dust removal device.

[0035] Please refer to Figures 1 - 8 , on the basis of the above embodiment, in another embodiment of the present invention, a collection device for collecting dust and a pushing device for accelerating the gas flow are provided inside the box body 1. By setting the collection device, it is ensured that the dust can be collected centrally. By setting the pushing device, the residence time of the gas in the device is reduced.

[0036] The collection device includes an elastic telescopic rod II 161, a scraping rod II 162, an inclined plane block 163, a partition net 164, and a push rod 165. The elastic telescopic rod II 161 is fixedly installed on the inner wall of the box body 1. The scraping rod II 162 is fixedly installed at the movable end of the elastic telescopic rod II 161. The inclined plane block 163 is fixedly installed on the top of the scraping rod II 162. The partition net 164 is fixedly installed between the box body 1 and the air outlet pipe 4. The push rod 165 is fixedly installed at the bottom of the sleeve 8. By moving the scraping rod II 162 to contact and clean the partition net 164, the air outlet is ensured to be unobstructed, the gas flow efficiency is improved, the resistance of gas flow is reduced, the energy consumption of the fan is reduced, thereby reducing the operation cost. At the same time, the corrosion and wear of the partition net 164 by dust are reduced, and the service life of the equipment is prolonged.

[0037] The collection device further includes a flap 166, a fixed block 167, a sliding rod 168, and a poking rod 169. The flap 166 is rotatably installed on the inner wall of the box body 1. The fixed block 167 is fixedly installed on the inner wall of the box body 1. The sliding rod 168 is rotatably installed on the top of the flap 166. The poking rod 169 is rotatably installed on the bottom of the flap 166. When the collection port is opened, the dust adsorbed on the discharge plate 10 can be centrally collected, ensuring that the dust is completely removed, thereby improving the dust removal efficiency. When the collection port is closed, the dust can be prevented from re-entering the air flow, preventing secondary dust generation and ensuring the dust removal effect.

[0038] The surfaces of the scraping rod II 162 in contact with the partition net 164 and the push rod 165 in contact with the inclined plane block 163 are both set as inclined planes. A first spring is provided between the sliding rod 168 and the inner wall of the box body 1. By contact, it is ensured that the scraping rod II 162 can clean the partition net 164 when moving. By setting the inclined plane, it is ensured that the push rod 165 can smoothly push the inclined plane block 163 when moving. By setting the first spring, it is ensured that the sliding rod 168 can achieve self-resetting.

[0039] The pushing device includes a fixing plate 171, a motor II 172, a rotating shaft 173, and a fan blade 174. The fixing plate 171 is fixedly installed on the inner wall of the air outlet pipe 4. The motor II 172 is fixedly installed on the right side of the fixing plate 171. The rotating shaft 173 is fixedly installed at the output end of the motor II 172. The fan blade 174 is fixedly installed on the circumferential surface of the rotating shaft 173. By rotating the fan blade 174 to accelerate the gas flow rate inside the air outlet pipe 4, the purified gas can be quickly discharged from the device, reducing the residence time of the gas in the device, improving the overall treatment efficiency. At the same time, it prevents the purified gas from flowing back into the dust removal device, avoiding secondary pollution or abnormal operation of the equipment.

[0040] The driving device further includes a fixed box 175, a filter plate 176, an elastic telescopic rod three 177, a pull ring 178, an L-shaped rod 179, an inclined plane rod 1710 and a clamping plate 1711. The fixed box 175 is fixedly installed inside the air outlet pipe 4. The filter plate 176 is slidably installed inside the fixed box 175. The elastic telescopic rod three 177 is fixedly installed at the front of the filter plate 176. The pull ring 178 is fixedly installed at the movable end of the elastic telescopic rod three 177. The L-shaped rod 179 is fixedly installed on the back of the pull ring 178. The inclined plane rod 1710 is slidably installed at the front of the filter plate 176. The clamping plate 1711 is fixedly installed at the front of the fixed box 175. By moving the inclined plane rod 1710 to contact the clamping plate 1711 and restrict the filter plate 176, the filter plate 176 will not be displaced during operation to ensure that the air flow passes through the filter plate 176 evenly, enabling the dust to fully contact the filter plate 176 and be captured, thereby improving the dust removal efficiency. At the same time, restricting the movement of the filter plate 176 can reduce the friction between the filter plate 176 and other components, reduce the wear of the filter plate 176, and extend its service life.

[0041] The surfaces of the L-shaped rod 179 and the inclined plane rod 1710 that are in contact with each other are both provided with inclined planes. A second spring is provided between the inclined plane rod 1710 and the filter plate 176. By setting the inclined plane, it is ensured that the L-shaped rod 179 can smoothly push the inclined plane rod 1710 when moving. By setting the second spring, it is ensured that the inclined plane rod 1710 can achieve self-resetting.

[0042] During the operation of this embodiment: While the sleeve 8 is moving, it drives the push rod 165 to start moving. The push rod 165 moves to contact and push the inclined plane block 163 to start moving downward. The movement of the inclined plane block 163 drives the scraping rod two 162 to start moving downward. The scraping rod two 162 moves to contact and clean the partition net 164, ensuring the smoothness of the air outlet, improving the gas flow efficiency, reducing the resistance of gas flow, reducing the energy consumption of the fan, thereby reducing the operating cost. At the same time, it reduces the corrosion and wear of the partition net 164 by dust and extends the service life of the equipment. While the scraping rod two 162 is moving downward, it contacts and pushes the sliding rod 168 to start moving downward. The movement of the sliding rod 168 drives the flap 166 to start rotating. The rotation of the flap 166 opens the discharge port between the box body 1 and the discharge pipe 5. After the scraping rod two 162 no longer pushes the sliding rod 168, the sliding rod 168 starts to move back under the action of the first spring. The movement of the sliding rod 168 drives the flap 166 to start rotating. The rotation of the flap 166 closes the discharge port between the box body 1 and the discharge pipe 5. By opening the collection port, the dust adsorbed on the discharge plate 10 can be centrally collected to ensure that the dust is completely removed, thereby improving the dust removal efficiency. When the collection port is closed, it can prevent the dust from re-entering the air flow and prevent secondary dust flying, ensuring the dust removal effect.

[0043] After the gas is cleaned by passing through the discharge plate 10, it continuously moves downward through the air outlet pipe 4 to the next processing step. At this time, the operator starts the second motor 172, causing the second motor 172 to drive the rotating shaft 173 to start rotating. The rotation of the rotating shaft 173 drives the fan blades 174 to start rotating. The rotation of the fan blades 174 accelerates the gas flow rate inside the air outlet pipe 4, enabling the purified gas to be quickly discharged from the device, reducing the residence time of the gas in the device, improving the overall processing efficiency, and preventing the purified gas from flowing back into the dust removal device, avoiding secondary pollution or abnormal equipment operation. After the gas enters the air outlet pipe 4, it will be secondarily processed by the filter plate 176 to clean up a small amount of dust that may be mixed in. When it is necessary to replace or clean the filter plate 176 after the work is completed, the operator holds the handle of the filter plate 176 and pulls the pull ring 178. The pull ring 178 starts to move under the pull of the operator and drives the L-shaped rod 179 to start moving. The L-shaped rod 179 moves away from the contact with the inclined surface rod 1710. Subsequently, the inclined surface rod 1710 starts to move and reset under the action of the second spring. The inclined surface rod 1710 moves away from the contact with the clamping plate 1711 and releases the restriction on the filter plate 176. At this time, the operator pulls out the filter plate 176 for replacement or cleaning. After the replacement or cleaning is completed, the filter plate 176 is placed back inside the fixed box 175. Stop pulling the pull ring 178 so that the movable end of the third elastic telescopic rod drives the pull ring 178 to start moving. The movement of the pull ring 178 drives the L-shaped rod 179 to start moving. The L-shaped rod 179 moves into contact with and pushes the inclined surface rod 1710 to start moving. The inclined surface rod 1710 moves into contact with the clamping plate 1711 and restricts the filter plate 176, so that the filter plate 176 will not be displaced during operation to ensure uniform air flow through the filter plate 176, enabling the dust to fully contact the filter plate 176 and be captured, thereby improving the dust removal efficiency. At the same time, restricting the movement of the filter plate 176 can reduce the friction between the filter plate 176 and other components, reduce the wear of the filter plate 176, and extend its service life.
