Description
Technical Field
[0001] This invention belongs to the field of workshop dust treatment technology, specifically referring to a dust treatment device for a forklift counterweight production workshop. Background Technology
[0002] Forklifts, as common industrial handling vehicles, are widely used in enterprises for transporting and loading / unloading goods. The rear of the forklift is equipped with a counterweight, the main function of which is to increase the weight of the forklift, help prevent the forklift from tilting or losing balance when lifting heavy objects, and improve the stability of the forklift. Forklift counterweights are generally processed by casting. After casting, the mold is removed and the surface is treated. Cutting, grinding and polishing steps are required in the production workshop, which generates a lot of dust and threatens the health of workers.
[0003] Traditional dust control methods often employ water vapor spraying or baghouse dust collectors. However, the dust generated during the production of forklift counterweights contains a large amount of metal powder. Water vapor spraying requires additional dust collection, and the resulting wastewater needs to be treated before discharge. Baghouse dust collectors are difficult to separate metal dust from other impurities, which is not conducive to metal recycling. Furthermore, the replacement and cleaning of the filter bags is difficult, affecting dust control efficiency. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a dust treatment device for forklift counterweight production workshops capable of separating metal powder from other impurities and automatically cleaning the screen. Utilizing a lever-based and electromagnetic principle, a lever-type continuous adsorption assembly is designed. The first and second adsorption mechanisms move alternately up and down, cyclically adsorbing and shaking off metal powder to collect it. This ensures continuous metal powder collection and processing, eliminating processing gaps and improving the collection rate of metal powder while simultaneously increasing dust separation efficiency. Furthermore, the reciprocating filtration mechanism dynamically cleans the filter screen while changing its filtration range, ensuring effective filtration. An anemometer automatically detects the filtration effect of the filter screen, further enhancing dust treatment efficiency.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a dust treatment device for a forklift counterweight production workshop, comprising a treatment box, wherein the treatment box includes an adsorption cover and a control cover, the control cover is disposed above the adsorption cover, the control cover is provided with a lever-type continuous adsorption assembly inside, a vibration-type pretreatment assembly is connected to one side of the control cover, a circulating filter assembly is connected to the other side of the control cover, a back box is connected to the side of the circulating filter assembly away from the control cover, a fan is disposed in the back box, and an air outlet is connected to the output end of the fan, wherein the lever-type continuous adsorption assembly includes a first adsorption mechanism, a second adsorption mechanism, an alternating connecting rod and a control mechanism, the first adsorption mechanism and the second adsorption mechanism are symmetrically disposed inside the control cover, the alternating connecting rod is rotatably connected to both sides of the first adsorption mechanism and the second adsorption mechanism, and the control mechanism is symmetrically disposed on both sides of the first adsorption mechanism;
[0006] Furthermore, the circulating filter assembly includes a sliding support frame, a reciprocating filtration mechanism, and an electric push rod. The sliding support frame is connected between the control housing and the back box. The reciprocating filtration mechanism is located inside the sliding support frame. The electric push rod is located at the top of the control housing, and the output end of the electric push rod is connected to the reciprocating filtration mechanism.
[0007] Furthermore, the control housing is symmetrically provided with a first limiting plate and a second limiting plate inside. The second limiting plate is located inside the first limiting plate. The second limiting plate is symmetrically provided with a sliding groove and a vibration groove, which penetrate the second limiting plate. The vibration groove is located outside the sliding groove. Conductor strips are symmetrically embedded on the side wall of the first limiting plate facing the second limiting plate. A control groove is provided inside the symmetrical conductor strips. The control groove is corresponding to the sliding groove on the side near the vibratory pretreatment component. The adsorption cover has a dust collection box that slides inside. The dust collection box can be pulled out from the side wall of the adsorption cover. The upper wall of the adsorption cover has symmetrically through-hole collection slots that connect the control cover and the dust collection box. The collection slots are located inside the second limiting plate and have a sloping edge. The side wall of the collection slots is perpendicular to the second limiting plate. The upper wall of the adsorption cover has symmetrically through-hole extension slots that are located on both sides of the collection slots. The extension slots are connected to the space between the first limiting plate and the second limiting plate.
[0008] Furthermore, the first adsorption mechanism and the second adsorption mechanism have the same structure and size, and the first adsorption mechanism and the second adsorption mechanism are respectively movably disposed inside the collection channel;
[0009] Furthermore, the first adsorption mechanism includes a connecting frame, an adsorption electromagnetic rod, a movable connecting block, and a pushing electromagnet. The connecting frame is in the shape of an inverted chamfer, with both ends of the connecting frame slidably disposed in sliding grooves. The adsorption electromagnetic rods are vertically and evenly distributed on the inner side of the connecting frame. The movable connecting blocks are symmetrically disposed at both ends of the connecting frame and are movably disposed between the first limiting plate and the second limiting plate. The pushing electromagnet is disposed on the side wall of the movable connecting block away from the second adsorption mechanism. The pushing electromagnet has a conductive connection point embedded in the side wall facing the first limiting plate, and the conductive connection point slides on the conductor strip.
[0010] Preferably, the two ends of the alternating link are rotatably connected to the ends of the connecting frames of the first adsorption mechanism and the second adsorption mechanism, respectively, and the alternating link is rotatably positioned between the first limiting plate and the second limiting plate.
[0011] Furthermore, a magnetic block is movably disposed below the driving electromagnet, the magnetic block having the same magnetic poles as the driving electromagnet. A vibrating spring is connected between the magnetic block and the adsorption cover, the vibrating spring being disposed within an extension groove. A transition connecting rod is disposed through the second limiting plate on the magnetic block, the transition connecting rod sliding up and down within the vibrating groove. A vibrating rod is vertically disposed above the transition connecting rod, the vibrating rod being disposed below the connecting frame, and the vibrating rod being disposed between the outermost adsorption electromagnet and the connecting frame. The length of the vibrating rod is greater than the distance between the upper wall of the connecting frame and the lower wall of the driving electromagnet. The upper end of the vibrating rod is covered with a rubber buffer layer, so that when the vibrating rod collides with the connecting frame, the magnetic block and the driving electromagnet do not come into contact, avoiding damage to the magnetic block or the driving electromagnet and ensuring the service life of the device.
[0012] Furthermore, the control mechanism includes a guide groove and a control motor. The guide groove is horizontally disposed on the outside of the moving connecting block. The guide groove is movably disposed between the first limiting plate and the side wall of the control housing. The guide groove slides up and down in the control groove. The control motor is disposed on the outer side wall of the control housing. The output end of the control motor is provided with an alternating rotating rod through the side wall of the control housing. The end of the alternating rotating rod away from the control motor is slidably disposed in the guide groove.
[0013] In use, the control motor starts, and when the end of the alternating rotating rod rotates to the uppermost position, the guide groove slides to the uppermost position of the control groove, thereby driving the moving connecting block and the connecting frame to move to the uppermost position of the sliding groove. The conductive connection point contacts the conductor strip, thereby conducting the closed circuit formed by the conductor strip, the conductive connection point, the pushing electromagnet, and the adsorption electromagnetic rod, causing the pushing electromagnet and the adsorption electromagnetic rod to be energized and generate magnetism. The array of adsorption electromagnetic rods adsorbs metal powder in the dust-laden gas, while the magnetic block below the first adsorption mechanism, under the elastic thrust of the vibrating spring, causes its corresponding transition connecting rod to slide to the upper end of the vibrating groove. The vibrating rod and the connecting frame... There is a certain distance between them. At this time, according to the lever principle, the connecting frame in the second adsorption mechanism at the other end of the alternating rod moves down to the lowest end of the sliding groove. As the alternating rod gradually rotates to the lowest end, the end of the alternating rod slides in the guide groove, thereby driving the moving block and connecting frame in the first adsorption mechanism to move down in the sliding groove. During its downward movement, the conductive connection point contacts the conductor strip, and the adsorption electromagnetic rod continuously adsorbs the metal powder, thereby driving the electromagnet to generate magnetism. The magnetic poles of the electromagnet and the magnetic block are the same. Therefore, during the downward movement of the electromagnet, the magnetic block below it is pushed by electromagnetic repulsion. The moving arm moves downwards, maintaining a distance between the electromagnet and the magnetic block. The vibrating spring compresses, and the transition connecting rod moves downwards within the vibrating groove until the alternating rotating rod drives the moving connecting block to gradually slide towards the bottom of the sliding groove. The conductive connection point slides past the conductor strip and no longer contacts it, breaking the circuit formed by the conductor strip, conductive connection point, moving electromagnet, and adsorption electromagnetic rod. The adsorption electromagnetic rod and moving electromagnet lose their magnetism and are no longer attracted to metal powder. At this point, the adsorption electromagnetic rod also moves downwards into the collecting channel. Meanwhile, the magnetic block, without the electromagnetic repulsion of the moving electromagnet, moves upwards under the elastic action of the vibrating spring, causing the vibrating rod to... The upper end of the vibrating rod impacts the connecting frame, and the rebound force generated by the impact compresses and rebounds the vibrating spring again, causing the vibrating rod to repeatedly impact the connecting frame. This causes the metal powder on the adsorption electromagnetic rod to fall rapidly into the dust collection box. At the same time, the second adsorption mechanism moves upward, and the adsorption electromagnetic rod on it conducts magnetic adsorption of the metal powder. Similarly, under the rotation of the alternating rotating rod, the first and second adsorption mechanisms move up and down alternately, cyclically adsorbing and shaking off the metal powder and collecting it. This makes the collection and processing of metal powder continuous, eliminating processing gaps, improving the collection rate of metal powder, and increasing the efficiency of dust separation and processing.
[0014] Preferably, a first cleaning cover is connected to the side of the sliding support facing the control cover, and the first cleaning cover is symmetrically arranged on both sides of the control cover. A second cleaning cover is connected to the side of the sliding support near the back box, and the second cleaning cover is symmetrically arranged on both sides of the back box. A transparent baffle is symmetrically arranged on the side of the sliding support facing the control cover, and the transparent baffle is located outside the first cleaning cover. A clearance groove is provided through the upper wall of the sliding support, and the output end of the electric push rod slides in the clearance groove.
[0015] Furthermore, the reciprocating filtration mechanism includes a filter screen, a scraping cleaning roller, and a tapping cleaning roller. The filter screen is slidably mounted within a sliding support frame. The output end of the electric push rod is connected to the upper end of the filter screen. The filter screen slides in contact with the control housing. A rack is provided at the bottom of the filter screen. A follower gear and a cleaning gear are rotatably mounted on the bottom wall of the sliding support frame. The follower gear and the cleaning gear are symmetrically arranged on both sides of the back box. The follower gear is located between the rack and the cleaning gear. The tack cleaning roller is coaxially mounted on the cleaning gear and meshes with the rack and the cleaning gear respectively. The tack cleaning roller is rotatably mounted inside the second cleaning housing. The bristles of the tack cleaning roller are made of rubber. The scraping cleaning roller is symmetrically rotatably mounted on the bottom wall of the sliding support frame. The scraping cleaning roller is located inside the first cleaning housing. The tack cleaning roller and the scraping cleaning roller are respectively located on both sides of the filter screen. The rotating shaft of the follower gear and the rotating shaft of the scraping cleaning roller respectively pass through the bottom wall of the sliding support frame and are connected by a transmission belt.
[0016] When the filtration efficiency of the filter screen between the control housing and the back box decreases, the electric push rod drives the filter screen to slide within the sliding support frame, moving another part of the filter screen between the control housing and the back box to continue filtration. During this process, the rack slides and meshes with the follower gear, which rotates in the same direction as the rack. The rotation of the follower gear drives the cleaning gear meshing with it to rotate, which in turn causes the patting cleaning roller to rotate in the opposite direction to the rack. The rubber bristles of the patting cleaning roller rotate and open, continuously patting the back of the filter screen, accelerating the shaking off of dust and impurities on the filter screen surface. At the same time, the follower gear drives the scraping cleaning roller on one side of the filter screen surface to rotate via the transmission belt. The scraping cleaning roller rotates in the opposite direction to the filter screen, and the bristles of the scraping cleaning roller brush the filter screen surface, scraping off the dust and impurities. This achieves dynamic cleaning of the filter screen and ensures its filtration effect.
[0017] Furthermore, the vibratory pretreatment assembly includes a transition tube, a primary screening mechanism, a folded tube, and a dust suction port. The transition tube is connected to the side of the control housing away from the sliding support frame. A power motor is provided on one side of the transition tube, and a power gear is provided at the output end of the power motor. The primary screening mechanism is located inside the transition tube. The folded tube is connected to the end of the transition tube away from the control housing. The folded tube can be extended, retracted, and bent at will, facilitating installation in multiple locations within the workshop. A material discharge pipe is connected to the lower part of the connection between the folded tube and the transition tube. The material discharge pipe is located below the primary screening mechanism, and a recycling box is connected to the lower end of the material discharge pipe. The recycling box is located on one side of the adsorption housing and can be extracted from the same side as the dust collection box. The dust suction port is connected to the end of the folded tube.
[0018] Furthermore, the primary screening mechanism includes a fixed ring, a toothed ring, a primary screening screen, a conical rotating rod, and a guide fan. The fixed ring is located inside the transition tube, and a fixed connecting rod is connected to the middle of the fixed ring, passing through the center of the fixed ring. The toothed ring is rotatably located on the side of the fixed ring near the folded tube, and meshes with a power gear. The primary screening screen is slidably located inside the toothed ring, and the primary screening screen and the toothed ring are axially slidable. When the toothed ring rotates, it drives the primary screening screen to rotate. The conical rotating rod passes through the primary screening screen. The center of rotation is located on a fixed connecting rod. The end of the cone-shaped rotating rod is conical. The primary screen is slidably sleeved on the cone-shaped rotating rod. The guide fan is evenly distributed around the primary screen on the side near the folded tube. The guide fan is sleeved on the cone-shaped rotating rod. A spring is connected between the end of the guide fan away from the primary screen and the conical end of the cone-shaped rotating rod. The spring is sleeved on the cone-shaped rotating rod. Due to the connection of the spring, when the primary screen and the guide fan rotate, the cone-shaped rotating rod rotates synchronously with the guide fan on the fixed connecting rod.
[0019] Preferably, the fixed connecting rod is provided with a blocking block on the side wall facing the primary screen, and the primary screen is provided with vibrating ramps evenly distributed around the circumference of the side facing the fixed connecting rod. The slope of the vibrating ramps is in the same direction as the rotation direction of the primary screen, and the blocking block is located on the running trajectory of the vibrating ramps.
[0020] In operation, the motor starts, and the power gear drives the gear ring to rotate. The primary screen rotates with the gear ring. The guide fan is connected to the primary screen and rotates with it. The rotation of the guide fan promotes the flow of gas containing dust. The primary screen filters out large metal fragments from the dust. As the primary screen rotates with the gear ring, the vibrating ramp also rotates. When the vibrating ramp rotates to the blocking block, the end of the blocking block slides along the slope of the vibrating ramp and pushes the primary screen and guide fan against the end of the cone-shaped rotating rod. The spring is compressed. When the blocking block completely slides past the vibrating ramp, the primary screen hits the fixed connecting rod under the elastic pressure of the spring. This cycle continues, and the primary screen vibrates back and forth on the cone-shaped rotating rod while rotating, causing the large metal fragments filtered by the primary screen to vibrate and fall into the feed pipe and be collected by the recovery box, thus separating the large metal fragments from the gas.
[0021] Furthermore, the back box is equipped with a wind speed detector, which is a UT363 anemometer. The processing box is equipped with a main controller, which is a PLC controller with the model number CJ1W-OD232. The power motor, control motor, conductor strip, electric push rod, wind speed detector and fan are electrically connected to the main controller. The conductive connection point, the pushing electromagnet and the adsorption electromagnet are connected in series by wires.
[0022] The beneficial effects achieved by the present invention using the above structure are as follows:
[0023] 1. The present invention provides a dust treatment device for a forklift counterweight production workshop. First, a primary screening mechanism filters out large metal fragments in the dust. Then, a lever-type continuous adsorption component removes metal powder from the dust through continuous electromagnetic adsorption. Finally, a reciprocating filtration mechanism filters out other dust impurities, thus completing the dust purification process and separating metal powder from other powder impurities. This ensures dust treatment efficiency while improving the metal recycling rate.
[0024] 2. Utilizing the lever principle combined with the electromagnetic principle, a lever-type continuous adsorption component is set up. Under the rotation of the alternating rotating rod, the first adsorption mechanism and the second adsorption mechanism move up and down alternately, cyclically adsorbing and shaking off metal powder and collecting the powder, so that the collection and processing of metal powder is continuous, there is no processing gap, the collection rate of metal powder is improved, and the efficiency of dust separation and processing is increased.
[0025] 3. By setting up a reciprocating filtration mechanism, dynamic cleaning of the filter screen is achieved while changing the filtration range, ensuring the filtration effect of the filter screen. The filtration effect of the filter screen is automatically detected by the wind speed detector, thereby improving the dust handling efficiency. Attached Figure Description

[0053] The processing box 1 is equipped with a main controller, which is a PLC controller with the model number CJ1W-OD232. The power motor 311, control motor 242, conductor strip 126, electric push rod 45, wind speed detector and fan are electrically connected to the main controller. The conductive connection 215, the pushing electromagnet 214 and the adsorption electromagnet 212 are connected in series by wires. When the conductive connection 215 contacts the conductor strip 126, the pushing electromagnet 214 and the adsorption electromagnet 212 are energized and generate magnetism.
[0054] Working principle and workflow:
[0055] In practical use, this device is installed in the production workshop. The air outlet 7 can face either outside or inside the workshop. The folding tube 8 can be extended, retracted, and bent arbitrarily for easy installation in the workshop. The suction port 6 is aligned with the process area in the production workshop where dust is generated in large quantities. The main controller is started, and the fan operates, creating negative pressure inside the device. Dust is drawn in through the suction port 6 and flows through the folding tube 8 to the primary screening mechanism 32. Simultaneously, the power motor 311 starts, and the power gear 312 drives the gear ring 323 to rotate. The primary screening screen 324 rotates with the gear ring 323. The guide fan 326 is connected to the primary screening screen 324 and rotates along with it. The rotation of the guide fan 326 further promotes the flow of dust-laden gas. The primary screening screen 324 filters out large particles in the dust. As the primary screen 324 rotates with the toothed ring 323, the vibrating ramp 329 also rotates. When the vibrating ramp 329 rotates to the blocking block 328, the end of the blocking block 328 slides along the slope of the vibrating ramp 329 and pushes the primary screen 324 and the guide fan 326 against the end of the cone-shaped rotating rod 325. The spring spring 327 is compressed. When the blocking block 328 has completely slid past the vibrating ramp 329, under the elastic pressure of the spring spring 327, the primary screen 324 hits the fixed connecting rod 322. This cycle continues, and the primary screen 324 vibrates back and forth on the cone-shaped rotating rod 325 while rotating. This causes the large metal fragments filtered by the primary screen 324 to vibrate and fall into the discharge pipe 33 and be collected by the recycling box 34.
[0056] Dust-laden gas, after removing large metal fragments, is drawn into the control housing 12 through the transition pipe 31. The control motor 242 starts. In the initial state, at least one set of conductive contacts 215 in the first adsorption mechanism 21 and the second adsorption mechanism 22 are in contact with the conductor strip 126. When the end of the alternating rotating rod 243 rotates to the uppermost position, the guide groove 241 slides to the uppermost position of the control groove 125, thereby driving the moving block 213 and the connecting frame 211 to move upward to the uppermost position of the sliding groove 123. The conductive contacts 215 contact the conductor strip 126, thereby completing the closed circuit formed by the conductor strip 126, the conductive contacts 215, the pushing electromagnet 214, and the adsorption electromagnetic rod 212, energizing the pushing electromagnet 214 and the adsorption electromagnetic rod 212. The array of electromagnetic rods 212 generates magnetism, adsorbing metal powder from the dust-laden gas. Meanwhile, the magnetic block 25 below the first adsorption mechanism 21, under the elastic thrust of the vibrating spring 26, causes its corresponding transition connecting rod 27 to slide to the upper end of the vibrating groove 124. A certain distance exists between the vibrating rod 28 and the connecting frame 211. At this time, according to the lever principle, the connecting frame 211 in the second adsorption mechanism 22 at the other end of the alternating connecting rod 23 moves down to the lowest end of the sliding groove 123. As the alternating rotating rod 243 gradually rotates to the lowest end, its end slides within the guide groove 241, thereby driving the moving connecting block 213 and the connecting frame 211 in the first adsorption mechanism 21 to move downwards within the sliding groove 123. During this downward movement, the guide... The electrical contact 215 contacts the conductor strip 126, and the adsorption electromagnetic rod 212 continuously adsorbs the metal powder. Meanwhile, the driving electromagnet 214 is energized and generates magnetism. The driving electromagnet 214 and the magnetic block 25 have the same magnetic poles. Therefore, during the downward movement of the driving electromagnet 214, the magnetic block 25 below it is pushed downward through electromagnetic repulsion. The driving electromagnet 214 and the magnetic block 25 maintain a distance at all times. The vibrating spring 26 is compressed, and the transition connecting rod 27 moves downward within the vibrating groove 124 until the alternating rotating rod 243 drives the moving connecting block 213 to gradually slide towards the bottom of the sliding groove 123. The conductive contact 215 slides past the conductor strip 126 and no longer contacts it, thus merging the conductor strip 126, the conductive contact 215, the driving electromagnet 214, and the adsorbed metal powder. The circuit formed by the magnetic rod 212 is broken, the adsorption electromagnetic rod 212 and the pushing electromagnet 214 are de-energized and lose their magnetism, the adsorption electromagnetic rod 212 no longer adsorbs metal powder, at this time the adsorption electromagnetic rod 212 also moves down into the collection channel 111, while the magnetic block 25 moves up under the elastic action of the vibrating spring 26 after the electromagnetic repulsion of the pushing electromagnet 214 is gone, causing the upper end of the vibrating rod 28 to hit the connecting frame 211. The rebound force generated by the impact causes the vibrating spring 26 to be compressed and rebounded again, thereby causing the vibrating rod 28 to hit the connecting frame 211 multiple times, causing the metal powder on the adsorption electromagnetic rod 212 to fall quickly into the dust collection box 13. At the same time, the second adsorption mechanism 22 moves up, and the adsorption electromagnetic rod 212 on it is turned on to generate magnetic adsorption of metal powder;Similarly, under the rotation of the alternating rotating rod 243, the first adsorption mechanism 21 and the second adsorption mechanism 22 move up and down alternately, cyclically adsorbing and shaking off metal powder and collecting it. This makes the collection and processing of metal powder continuous, eliminating processing gaps, improving the collection rate of metal powder, and increasing the efficiency of dust separation and processing.
[0057] Subsequently, the gas, after the metal powder is removed, contains only other dust and impurities. It flows through the sliding support 41 into the back box 5 and is discharged from the outlet 7. During this process, the gas passes through the filter screen 441 to remove impurities. The wind speed detector in the back box 5 detects the flow rate of the filtered gas. When the gas flow rate is lower than the minimum threshold of the wind speed detector, it indicates that there are many impurities on the filter screen 441 between the control housing 12 and the back box 5, affecting the filtration efficiency. At this time, the electric push rod 45 is activated, causing the filter screen 441 to slide within the sliding support 41, so that another part of the filter screen 441 moves between the control housing 12 and the back box 5 to continue the filtration work. During this process, the rack 442 slides and meshes with the follower gear 443. The follower gear 443 rotates in the same direction as the rack 442. The rotation of the follower gear 443 drives the rack 442 to move the filter screen 441 to the back box 5. The cleaning gear 444, which meshes with it, rotates, causing the patting cleaning roller 446 to rotate in the opposite direction to the rack 442. The rubber bristles of the patting cleaning roller 446 rotate and open, continuously patting the back of the filter screen 441, accelerating the shaking off of dust and impurities on the filter screen 441. At the same time, the follower gear 443 drives the scraping cleaning roller 445 on one side of the filter screen 441 to rotate via the transmission belt 447. The scraping cleaning roller 445 rotates in the opposite direction to the filter screen 441, and the bristles of the scraping cleaning roller 445 brush the filter screen 441, scraping off the dust and impurities on it, thus achieving dynamic cleaning of the filter screen 441 and ensuring its filtration effect. Similarly, when the wind speed detector reaches the minimum threshold again, the electric push rod 45 starts again to replace the cleaned filter screen 441 for dust filtration.
[0058] After vacuuming is complete, dust collection box 13 and recycling box 34 are extracted to recycle metal powder and large metal fragments.
[0059] The transparent baffle 411 allows for a direct observation of the surface condition of the filter screen 441 and the dust content inside the sliding support frame 41. When the wind speed detector continuously alarms the minimum threshold or when the dust content inside the sliding support frame 41 is high as observed through the transparent baffle 411, the first cleaning cover 42 and the second cleaning cover 43 can be opened to remove the scraping cleaning roller 445 and the tapping cleaning roller 446 for cleaning and dust removal, and to remove excess dust inside the sliding support frame 41.
[0060] It is worth noting that, since the length of the vibrating rod 28 is greater than the distance between the upper wall of the connecting frame 211 and the lower wall of the pushing electromagnet 214, when the vibrating rod 28 collides with the connecting frame 211, the magnetic block 25 does not contact the pushing electromagnet 214, thus avoiding damage to the magnetic block 25 or the pushing electromagnet 214. In addition, the frame of the filter screen 441 is in close contact with the inner wall of the sliding support 41, so gas cannot leak out from the relief groove 412. This will not be elaborated further here.
