Static electricity removing ultrasonic integrated dry dust removing system

Abstract

This invention discloses an integrated dry dust removal system for electrostatic removal using ultrasonic technology. It includes two parallel support bases, each with a conveyor plate on its inner side for conveying workpieces. During the cleaning process, the system utilizes a positioning plate and a height-fixing plate to position workpieces of different heights. This allows the profile body to automatically adjust the distance between itself and workpieces of varying heights based on the positions of the positioning and height-fixing plates, ensuring optimal cleaning distance and guaranteeing effective dust removal while improving cleaning efficiency. Furthermore, an electrostatic generator produces a large number of positive and negative ions, which are emitted through an electrostatic fan to neutralize static electricity adhering to the workpiece surface. This neutralization of static electricity during dust removal reduces the total time spent on both dust removal and electrostatic removal processes, further improving cleaning efficiency.

Description

Technical Field

[0001] This invention relates to the field of ultrasonic dust removal technology, specifically to an integrated dry dust removal system using electrostatic removal ultrasonic technology. Background Technology

[0002] An ultrasonic dust collector is a device that uses the special properties of ultrasound to remove particulate matter from the air. It is widely used in air purification and dust removal processes in industrial production, efficiently and quickly removing pollutants such as dust, smoke, and fine particles from the air, improving air quality and protecting production equipment and the working environment. The working principle of an ultrasonic dust collector mainly consists of three parts: an ultrasonic generator, a vibration system, and a microphone. First, the ultrasonic generator produces a high-frequency electrical signal, which is then converted into mechanical vibration by the vibration system. The vibration system is typically made of piezoelectric ceramic material; when the electrical signal passes through the piezoelectric ceramic, it causes mechanical vibration. Finally, the mechanical vibration converts the energy into ultrasonic waves through the microphone, which propagates the ultrasonic waves into the air, breaking down the air viscous layer on the material surface. The dust is then blown away by high-pressure oscillating air, removing it from the workpiece surface. Negative pressure air further removes the dust, resulting in non-contact dust removal—a highly efficient, safe, and clean dry dust removal device.

[0003] In the existing technology, when using ultrasonic dust removal devices to process workpieces, the ultrasonic dust removal head removes dust from the workpiece surface. During the process, the surface of the ultrasonic dust removal head will have a lot of dust adsorbed due to electrostatic discharge, which affects the subsequent dust removal effect, reduces the processing efficiency, and results in the workpiece surface not being thoroughly cleaned, thus affecting the subsequent use of the workpiece.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the process of cleaning dust from the surface of a workpiece, this invention utilizes a positioning plate and a height-fixing plate to position workpieces of different heights. This allows the profile body to automatically adjust the distance between itself and workpieces of different heights based on the positions of the positioning plate and the height-fixing plate, ensuring the optimal cleaning distance and guaranteeing the cleaning effect on the workpiece surface, thus improving cleaning efficiency. Furthermore, an electrostatic generator produces a large number of positive and negative ions, which are emitted through an electrostatic fan to neutralize the static electricity adhering to the workpiece surface. This neutralization of static electricity during dust removal reduces the total time for both dust removal and static electricity removal, further improving cleaning efficiency.

[0017] 2. In the process of cleaning the workpiece surface, the first rolling wheel moves along the connecting rod. When the first rolling wheel moves to the end of the connecting rod, it gradually moves downward along the bend at the end of the connecting rod. Then, the second rolling wheel moves to the surface of the first guide plate and rolls on the surface of the first guide plate. The second rolling wheel drives the rotating rod to rotate together. The two rotating rods rotate together under the action of the synchronous belt. The moving rod moves to the other side along the bottom of the protective cover under the action of the guide groove. When the cleaning brush moves to the position of the recycling port, part of the cleaning brush will extend into the recycling port under the action of the elastic force. The movement of the cleaning brush will brush and clean the inside and outside of the recycling port, thereby sweeping away the dust attached to the outside and inside of the cleaning port, thus ensuring the recycling effect of the cleaning port on the dust and improving the recycling efficiency.

[0018] 3. In the process of cleaning the workpiece surface, when the first rolling wheel moves to the outside of the connecting rod, the second rolling wheel moves to the surface of the first guide plate. Then, during the second cleaning of the workpiece surface by the profile body, when the first rolling wheel moves to the outside of the connecting rod again, there will be a second guide plate on the side away from the second rolling wheel. The third rolling wheel will move to the surface of the second guide plate, and then the third rolling wheel will rotate under the action of the second guide plate. The third rolling wheel will rotate in the opposite direction under the action of the rotating rod, and the moving rod can move in the opposite direction. This is beneficial for the moving rod and the cleaning brush to move back and forth during continuous cleaning of the workpiece, ensuring the cleaning of the recovery port, thereby ensuring the dust removal effect and improving the dust removal efficiency.

For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0033] Please see Figures 1-11 This invention provides a technical solution: an integrated dry dust removal system using ultrasonic antistatic technology, comprising two parallel support bases 1, with conveyor plates 2 on the inner sides of the two support bases 1 for conveying workpieces. The conveyor plates 2 are connected to an external driver, and a positioning mechanism is provided on the surface of the conveyor plates 2 for positioning the position and height of the workpieces. Mounting plates 3 are fixedly installed on the surfaces of both support bases 1, and a protective cover 4 is provided between the two mounting plates 3. The bottom of the protective cover 4 has an opening, and a first side plate 5 and a second side plate 6 are fixedly installed on the sides of the protective cover 4 near the two mounting plates 3, respectively. A pressure plate is fixedly connected to the surface of the protective cover 4. Table 7 shows that the protective cover 4 is equipped with an ultrasonic dust removal mechanism, which generates ultrasonic waves to treat dust on the surface of the workpiece. The ultrasonic dust removal mechanism is also equipped with an electrostatic elimination mechanism, which generates ions to neutralize the static electricity on the surface of the workpiece. The protective cover 4 is also equipped with a negative pressure absorption mechanism, which is used to adsorb and recycle the dust on the surface of the workpiece after it has been treated by the ultrasonic dust removal mechanism. An automatic adjustment mechanism is provided between the side plate and the mounting plate 3. The automatic adjustment mechanism is used to move the ultrasonic dust removal mechanism and the negative pressure absorption mechanism to the same cleaning distance above the workpiece at different heights according to the positioning mechanism.

[0034] The positioning mechanism includes two retractable positioning plates 8, which are fixedly connected to the surface of the conveyor plate 2. A retractable height plate 9 is fixedly connected to the surface of one side of the positioning plate 8, and the end of the height plate 9 is inclined.

[0035] The ultrasonic dust removal mechanism includes a profile body 10, which is fixedly installed between the first side plate 5 and the second side plate 6. The profile body 10 is located inside the protective cover 4. Two inclined partition plates 11 are fixedly connected inside the profile body 10. The profile body 10 is divided into a dust removal chamber 12 in the middle and negative pressure chambers 13 on both sides. An air outlet 14 is opened at the bottom of the inner wall of the dust removal chamber 12. A negative plate 15 is fixedly connected to the inner wall surface of the dust removal chamber 12 on both the left and right sides corresponding to the air outlet 14. The negative plate 15 is used to generate ultrasonic waves when the airflow passes through. An air inlet groove 16 is opened on the first side plate 5 corresponding to the position of the dust removal chamber 12. The air inlet groove 16 passes through the top of the first side plate 5. An air inlet pipe 17 is fixedly connected to the upper surface of the first side plate 5. The air inlet pipe 17 communicates with the air inlet groove 16.

[0036] The static electricity elimination mechanism includes an electrostatic bar 18, which is fixedly connected to the inner wall surface of the dust removal chamber 12 and is electrically connected to an external static electricity generator.

[0037] The negative pressure absorption mechanism includes two recovery ports 19, which are respectively opened at the bottom of the inner wall of the two negative pressure chambers 13. An exhaust groove 20 is opened on the surface of the second side plate 6 near the negative pressure chamber 13. The exhaust groove 20 is connected to the two negative pressure chambers 13. The upper end of the exhaust groove 20 passes through the second side plate 6. A negative pressure pipe 21 is fixedly connected to the surface of the second side plate 6. The negative pressure pipe 21 is connected to the exhaust groove 20.

[0038] The automatic adjustment mechanism includes two connecting rods 22, which are fixedly connected to the two positioning sides to connect the two positioning plates 8. A telescopic rod 23 is hinged to the side of the positioning plate 8 away from the fixed height plate 9. The telescopic rod 23 is hinged to the side of the conveying plate 2. Multiple fixing rods 24 are fixedly connected to the surface of the mounting plate 3. Sliding blocks 25 are fixedly connected to the surfaces of the first side plate 5 and the second side plate 6. The sliding blocks 25 slide on the surface of the fixing rods 24. The fixing rods 24 pass through the sliding blocks 25. An extension plate 26 is fixedly connected to the surface of the sliding blocks 25. The bottom of the extension plate 26 extends to below the profile body 10. A first rolling wheel 27 is rotatably connected to the surface of the extension plate 26. The first rolling wheel 27 is located above the connecting rods 22 and the telescopic rods 23.

[0039] During the dust removal process on the workpiece surface, the workpiece is first placed between two positioning plates 8. Then, the height-fixing plate 9 is pulled to hang on the upper surface of the workpiece. The two positioning plates 8 extend upwards together under the action of the connecting rod 22, and the telescopic rod 23 extends under the action of the positioning plates 8. Subsequently, the conveying plate 2 moves the workpiece closer to the profile body 10. When the first rolling wheel 27 moves to the position of the telescopic rod 23, the first rolling wheel 27 gradually moves upwards along the telescopic rod 23. The first rolling wheel 27 acts on the extension plate 26, sliding block 25, first side plate 5, second side plate 6, and profile body 10 to move upwards together. Then, when the first rolling wheel 27 moves to the position of the connecting rod 22, the profile body 10 is at the optimal cleaning distance above the workpiece surface. By using the positioning plates 8 and height-fixing plates 9 to position workpieces of different heights, the profile body 10 can automatically adjust the distance between itself and workpieces of different heights according to the positions of the positioning plates 8 and height-fixing plates 9 to maintain the optimal cleaning distance, thereby ensuring the effective cleaning of dust from the workpiece surface. To improve cleaning efficiency, during the cleaning of the workpiece surface, gas is introduced into the air inlet slot 16 and dust removal chamber 12 through the air inlet pipe 17. When the gas moves to the positions of the two negative plates 15 through the dust removal chamber 12, the air is compressed to generate ultrasonic waves, and the generated high-frequency oscillating air is discharged through the air outlet 14. The oscillating air blows up the dust adhering to the workpiece surface. During the process of treating the dust on the workpiece surface, the electrostatic generator generates a large number of positive and negative ions and emits them through the electrostatic fan bar 18, which can remove the dust adhering to the workpiece surface. The static electricity is neutralized during the dust removal process, reducing the total time of the dust removal and static electricity removal processes and improving cleaning efficiency. When the high-frequency oscillating air treats the surface of the workpiece, the gas is discharged through the negative pressure pipe 21, which causes the exhaust groove 20 and the negative pressure chamber 13 to generate negative pressure. The dust cleaned by the high-frequency oscillating air on the surface of the workpiece is recovered through the recovery ports 19 on both sides of the air outlet 14. The recovery ports 19 on both sides can recover the dust blown up from both sides of the air outlet 14, ensuring the cleanliness of the workpiece surface.

[0040] During the long-term processing of the workpiece surface, dust accumulates at the recovery port 19. As a further solution of the present invention, two rotating rods 28 are rotatably connected between the two extension plates 26. The two rotating rods 28 are located below the profile body 10, and the surfaces of the two rotating rods 28 are connected to a synchronous belt 29 for transmission. The rotating rod 28 on the side away from the first rolling wheel 27 passes through the extension plate 26, and one end of the rotating rod 28 on the side away from the first rolling wheel 27 is fixedly connected to a second rolling wheel 30. The side of the extension plate 26 away from the first rolling wheel 27 is inclined, and the conveying plate... A first guide plate 31 is fixedly connected to the surface of the second roller 30 below the second roller 30. The first guide plate 31 is located on the side of the connecting rod 22 away from the positioning plate 8 and on the side of the positioning plate 8 away from the telescopic rod 23. The end of the connecting rod 22 near the first guide plate 31 passes over the positioning plate 8 and then bends downward. A threaded guide groove 32 is opened on the surface of the rotating rod 28. A moving rod 33 is slidably connected to the bottom of the protective cover 4. The moving rod 33 slides in the guide groove 32 and extends to the position of the recycling port 19. A cleaning brush 34 is fixedly connected to the surface of the guide groove 32.

[0041] During the cleaning process of the workpiece surface, the first rolling wheel 27 moves along the connecting rod 22. When the first rolling wheel 27 moves to the end of the connecting rod 22, it gradually moves downward along the bend at the end of the connecting rod 22. Then the second rolling wheel 30 moves to the surface of the first guide plate 31 and rolls on the surface of the first guide plate 31. The second rolling wheel 30 drives the rotating rod 28 to rotate together. The two rotating rods 28 rotate together under the action of the synchronous belt 29. The moving rod 33 moves to the other side along the bottom of the protective cover 4 under the action of the guide groove 32. When the cleaning brush 34 moves to the position of the recycling port 19, part of the cleaning brush 34 will extend into the recycling port 19 under the action of elasticity. The movement of the cleaning brush 34 will brush and clean the inside and outside of the recycling port 19, thereby sweeping away the dust attached to the outside and inside of the cleaning port, thus ensuring the recycling effect of the cleaning port on the dust and improving the recycling efficiency.

[0042] During the cleaning process of the workpiece surface, the moving rod 33 and the cleaning brush 34 cannot move back and forth during continuous operation. As a further solution of the present invention, the end of the rotating rod 28 away from the second rolling wheel 30 passes through the extension plate 26, and the surface of the extension plate 26 away from the second rolling wheel 30 is rotatably connected to the third rolling wheel 35. The third rolling wheel 35 is in contact with the surface of the rotating rod 28, and the surface of the conveying plate 2 is fixedly connected to the second guide plate 36 corresponding to the position of the third rolling wheel 35. The second guide plate 36 and the first guide plate 31 are alternately distributed.

[0043] During the cleaning process of the workpiece surface, as described above, when the first roller 27 moves to the outside of the connecting rod 22, the second roller 30 will move to the surface of the first guide plate 31. Subsequently, during the second cleaning process of the profile body 10 on the workpiece surface, when the first roller 27 moves to the outside of the connecting rod 22 again, there will be a second guide plate 36 on the side away from the second roller 30, and the third roller 35 will move to the surface of the second guide plate 36. Then, the third roller 35 will rotate under the action of the second guide plate 36. The third roller 35 will cause the rotating rod 28 to rotate in the opposite direction, and the moving rod 33 can move in the opposite direction. This is beneficial for the moving rod 33 and the cleaning brush 34 to move back and forth during continuous cleaning of the workpiece, ensuring the cleaning of the recovery port 19, thereby ensuring the dust removal effect and improving the dust removal efficiency.

[0044] During the cleaning process of the cleaning brush 34 cleaning the recycling port 19, the cleaning brush 34 generates static electricity, causing dust to adhere to the surface of the cleaning brush 34. As a further embodiment of the present invention, a conductive sheet 37 is fixedly connected to the surface of the moving rod 33. The conductive sheet 37 extends to the position of the cleaning brush 34. A conductive rod 38 is fixedly connected between the two extension plates 26. The moving rod 33 slides on the surface of the conductive rod 38. The conductive sheet 37 contacts the conductive rod 38. The conductive rod 38 is connected to the external ground wire.

[0045] During the cleaning process of the workpiece surface, the moving rod 33 and the cleaning brush 34 will move back and forth under the profile body 10. The moving rod 33 will slide on the surface of the conductive rod 38. The static electricity attached to the surface of the cleaning brush 34 will be transferred to the external ground wire through the conductive sheet 37 and the conductive rod 38, thereby removing the static electricity attached to the surface of the cleaning brush 34 and ensuring that the cleaning brush 34 cleans the recovery port 19.

[0046] During the cleaning process of the workpiece surface, a lot of dust will be attached to the inside of the cleaning brush 34. As a further solution of the present invention, the first side plate 5 and the second side plate 6 are fixedly connected to the cleaning comb 39 at the positions corresponding to the cleaning brush 34.

[0047] During the cleaning process of the workpiece surface, when the moving rod 33 moves to the end of the guide grooves 32 on both sides, the cleaning brush 34 will move to the position of the cleaning comb 39. The cleaning comb 39 can clean the dust attached to the surface of the cleaning brush 34, thereby reducing the dust attached to the surface of the cleaning brush 34 and ensuring the cleaning of the recovery port 19.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
