Multiple traction devices for driving the gas cylinder body are installed on the suspended chain. Spraying machines are installed on both sides of the spray booth, used to spray the outer wall of the gas cylinder body passing through. A connecting pipe is installed between the spray booth, cyclone separator, filter cartridge, and collection box for dust transport. A vacuum pump (fan one and fan two) is installed on the connecting pipe, with fan one located at the end of the connecting pipe and fan two located at the top of the filter cartridge. A spraying device is installed inside the connecting pipe. A uniform liquid delivery component for intermittently delivering neutralizing and descaling liquid is installed above the collection box. A cleaning component for automatically cleaning the inner wall is installed inside the collection box.

[0006] The above technical solution involves connecting the spray booth, cyclone separator, filter cartridge, and collection box for spraying work through pipelines. A negative pressure vacuum environment is created using a fan installed on the pipeline to extract the dust generated during spraying. The dust is then passed through a multi-stage purification device, thus thoroughly purifying the dust multiple times, improving purification efficiency, and reducing harm to the environment and workers.

[0008] The above technical solution involves connecting the spray booth, cyclone separator, filter cartridge, and collection box sequentially through pipelines.

One end of a connecting rod is fixed to the outer wall of the connecting block. A sliding plate is fixed to the other end of the connecting rod. The connecting block is U-shaped. The connecting rod slides through the inner walls of the storage box, the outer shell, and the first humidification pipe. An isolation plate and a spring are provided on the inner wall of the storage box. A one-way valve is installed through the inner wall of the isolation plate. A liquid outlet pipe is connected to the bottom of the storage box and is located above the collection box.

[0010] The above technical solution utilizes airflow within the pipeline to drive the blades and rotating rods. The rotating rods and gears mesh to rotate the eccentric wheel, which in turn drives the sliding plate to slide back and forth, automatically and intermittently extracting the treatment liquid from the storage tank and mixing it with the dust mixture to improve processing efficiency.

[0011] As a further description of the above technical solution: Preferably, the limiting component includes multiple fixing blocks fixed to the outer wall of the collar, and multiple limiting rods are fixed to opposite sides of the inner wall of the outer shell, with the fixing blocks sliding on the outer wall of the limiting rods.

[0012] The above technical solution converts the rotation of the eccentric wheel into the reciprocating linear sliding of the collar through the limiting component, thereby driving the mutual components to move synchronously and achieving the effect of intermittent extraction.

[0013] As a further description of the above technical solution: Preferably, the partition plate divides the storage box into a liquid storage chamber and a liquid outlet chamber, the connecting rod and the sliding plate slide on the inner wall of the liquid outlet chamber, one end of the spring is fixed to the inner wall of the liquid outlet chamber, the other end of the spring is fixed to the outer wall of the sliding plate, the one-way valve is disposed between the liquid storage chamber and the liquid outlet chamber, and the liquid outlet pipe passes through the inner wall of the liquid outlet chamber.

[0014] The above technical solution achieves intermittent extraction and automatic discharge of liquid through a one-way valve installed on the isolation plate, eliminating the need for manual intervention and reducing labor costs.

[0015] As a further description of the above technical solution: Preferably, the cleaning assembly includes a second rotating shaft and a reciprocating screw. The second rotating shaft rotates on the inner wall of the fourth pipe and extends out at one end. A plurality of drive blades are evenly fixed on the outer wall of the second rotating shaft. The reciprocating screw rotates on the opposite side of the inner wall of the collection box. A cleaning frame is threadedly connected to the outer wall of the reciprocating screw. A plurality of sliding rods are fixed on the opposite side of the inner wall of the collection box. The outer wall of the cleaning frame is slidably connected to the inner wall of the collection box. The inner wall of the cleaning frame is slidably connected to the outer wall of the sliding rods. A transmission assembly for transmitting power is provided between the second rotating shaft and the reciprocating screw.

[0016] The above technical solution involves using a reciprocating screw to rotate and automatically slide the cleaning frame back and forth, scraping the inner wall of the collection box repeatedly to achieve automatic cleaning.

[0017] As a further description of the above technical solution: Preferably, the transmission assembly includes a bevel gear three fixed to the outer wall of the rotating shaft two and a protective shell fixed to the top of the collection box. A worm gear rotates on the opposite side of the inner wall of the collection box and the protective shell. A bevel gear four is fixed to the outer wall of the worm gear.

[0020] The above technical solution achieves controllable rotation and speed reduction through the cooperation of worm gears and large and small gears, ensuring the stable operation of the cleaning components.

[0021] As a further description of the above technical solution: Preferably, the spraying device includes a water tank disposed above the collection box and a plurality of spray heads installed on the inner walls of the first humidifying pipe and the second humidifying pipe. The inner wall of the water tank is provided with water storage, and the water tank and the spray heads are connected for spraying the stored water.

[0022] The above technical solution involves connecting a spray head to a water tank containing water, spraying the passing dust, causing it to mix with the water and fall to the bottom, thus completely purifying it.

[0023] As a further description of the above technical solution: Preferably, the traction device causes the gas cylinder body to be transported along the length extension direction of the spray chamber while rotating the gas cylinder body in the horizontal plane. The bottom end of the spray chamber is provided with an inclined collection groove, and the connecting pipe is installed through the inner wall of the inclined collection groove. Multiple filter elements are installed inside the filter element filter. The bottom end of the filter element is provided with a dust collection cart for collecting dust. The second fan is located directly above the multiple filter elements.

[0024] The above technical solution ensures that the gas cylinder is completely coated by the traction device, and the initial collection of dust is achieved by the inclined collection trough, so that it is completely drawn into the subsequent purification device by the pipeline. Through the cooperation of the collection box at the bottom of the separator, the dust accumulation cart at the bottom of the filter, and the collection box, the dust is completely collected for subsequent use.

[0025] Working Principle: When using this system for cylinder painting and dust purification, the cylinders are transported to the spray booth via a suspended chain. The traction device on the chain causes the cylinders to rotate, activating the paint sprayer and evenly coating each cylinder with plastic powder. Simultaneously, blowers one and two start, generating suction that draws residual plastic powder powder along the extraction pipe to the cyclone separator. The cyclone separator separates the powder powder from the airflow into a collector below. This powder powder can be reused. Fine dust particles that cannot be collected by the cyclone separator are further drawn by the suction from the two blowers along pipe one into the filter cartridge for filtration. Inside the filter, multiple filter cartridges filter the dust. The dust that settles inside the filter cartridges falls into the dust collection cart at the bottom for recycling. The dust remaining in the air is continued to be drawn away by the fan along pipe two into the first humidifying pipe. The spray head in the first humidifying pipe sprays the dust, causing the dust and water mixture to fall into the collection box at the bottom. At the same time, the remaining dust in the first humidifying pipe continues to move along pipe three into the second humidifying pipe due to the suction of the fan. The spray head in the second humidifying pipe continues to spray the dust, causing the dust and water mixture to also fall into the collection box at the bottom. The dust is further filtered through the two pipes with spray heads. Meanwhile, a storage tank is set between the first and second humidifying pipes, and above the collection tank. The tank contains descaling agent and neutralizing liquid. Inside the third pipe, a rotating shaft is installed, with multiple drive blades evenly fixed on its outer wall to collect airflow. When the suction generated by the fan moves dust along the third pipe, the airflow drives the drive blades and rotating shaft to rotate. This rotation is then driven by gear meshing and rotates the turntable. Through the action of the eccentric wheel and the limiting component, the rotational force is converted into the force of the connecting rod sliding back and forth in a straight line. The connecting rod then drives the sliding plate connected to it to slide along the inner wall of the storage tank, thereby drawing the liquid stored above the storage tank into the lower part through a one-way valve and intermittently transporting it to the outlet pipe. The liquid then enters the collection tank below, where it mixes with the liquid mixture containing dust, reacts and neutralizes it, facilitating further processing. Meanwhile, the collection box is equipped with a rotating reciprocating screw, which is driven by a rotating shaft with a drive blade installed inside the pipe through a transmission component. This allows the reciprocating screw to be driven to rotate by suction. When the reciprocating screw rotates, it drives the cleaning frame connected to its outer wall to slide back and forth along the direction of the reciprocating screw. The outer wall of the cleaning frame abuts against the inner wall of the collection box to automatically clean the collection box and prevent dust and other particles from solidifying and adhering.

[0026] This invention provides a dust purification system. It has the following beneficial effects: 1. In this invention, a spray booth, cyclone separator, filter cartridge and collection box for spraying are connected step by step through a connecting pipe. A fan installed on the pipe creates a negative pressure vacuum environment in the pipe to extract the generated dust and make it pass through a multi-stage purification device in sequence, thereby fully purifying the dust multiple times and reducing the harm to the environment and workers.

[0027] 2. In this invention, the airflow drives the rotating shaft and eccentric column to rotate. The eccentric column and the limiting component work together to drive the connecting block to slide back and forth in a straight line, which in turn drives the sliding plate to slide synchronously in the storage box. The one-way valve is used to automatically extract and discharge the treatment liquid intermittently, so as to pre-treat the dust mixture and save the use and cost of the treatment liquid.

[0028] 3. In this invention, the rotation of the reciprocating screw is driven by the cooperation of airflow and transmission components, which in turn drives the cleaning frame to slide back and forth automatically, scraping the inner wall of the collection box back and forth, thus achieving the effect of automatic cleaning.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To better understand the above technical solutions, the technical solutions of the present invention will be clearly and completely described below in conjunction with embodiments.

[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 This invention provides a dust purification system, including a suspended chain 1, a spray booth 4, a cyclone separator 6, a filter cartridge 7, and a collection box 8. Multiple traction devices 2 for driving the gas cylinder body 3 are installed on the suspended chain 1. Spraying machines 5 are installed on both sides of the spray booth 4, used to spray the outer wall of the gas cylinder body 3. A connecting pipe 12 is installed between the spray booth 4, the cyclone separator 6, the filter cartridge 7, and the collection box 8, for conveying dust. A vacuum pump 10 and a vacuum pump 11 are installed on the connecting pipe 12. The vacuum pump 10 is located at the end of the connecting pipe 12, and the vacuum pump 11 is located at the top of the filter cartridge 7. A spraying device is installed inside the connecting pipe 12. A uniform liquid delivery component for intermittently conveying neutralizing and descaling liquid is installed above the collection box 8. A cleaning component for automatically cleaning the inner wall is installed inside the collection box 8.

[0034] Specifically, the system mainly consists of a suspension chain 1, a traction device 2 for moving and rotating the gas cylinder body 3, a spray booth 4, a spraying machine 5, a cyclone separator 6, a filter cartridge 7, a collection box 8, a first fan 10, a second fan 11, a connecting pipe 12 for dust conveying, and a spraying device. The traction device 2 is mounted on the suspension chain 1, which sends the gas cylinder body 3 into the spray booth 4. The spraying machine 5 is installed on both sides of the spray booth 4. The cyclone separator 6, the filter cartridge 7, and the collection box 8 are sequentially arranged outside the spray booth 4 and connected by a sealed connection. The connecting pipe 12 sequentially connects the spray booth 4, cyclone separator 6, filter cartridge 7, and collection box 8. By using a second fan 11 located in the middle of the connecting pipe 12 and a first fan 10 located at the end, a vacuum is created in the connecting pipe 12 to form a negative pressure environment, thereby extracting the dust falling from the bottom of the spray booth 4. The dust is then sequentially processed through the device along the connecting pipe 12 for multi-stage purification. The system also includes a uniform liquid delivery component and a cleaning component to process the mixture of dust and water in real time, reducing subsequent labor and improving the system's practicality.

[0035] Please see the appendix Figure 3 and attached Figure 5 The connecting pipes 12 include a powder extraction pipe 1201, a first pipe 1202, a second pipe 1203, a first humidification pipe 1204, a third pipe 1205, a second humidification pipe 1206, and a fourth pipe 1207. One end of the powder extraction pipe 1201 is installed at the bottom of the spray booth 4, and the other end of the powder extraction pipe 1201 is connected to the input end of the cyclone separator 6. One end of the first pipe 1202 is connected to the output end of the cyclone separator 6, and the other end of the first pipe 1202 is connected to the input end of the filter cartridge 7. One end of pipe 1203 is connected to the output end of filter cartridge 7, and the other end of pipe 1203 is connected to the first humidifying pipe 1204. The bottom ends of the first humidifying pipe 1204 and the second humidifying pipe 1206 are connected and set above the collection box 8. The two ends of pipe 1205 are connected to the inner walls of the first humidifying pipe 1204 and the second humidifying pipe 1206 respectively. One end of pipe 1207 is connected to the inner wall of the second humidifying pipe 1206. Fan 10 is installed at the other end of pipe 1207.

[0036] Specifically, when plastic powder dust falls into the bottom of the spray booth 4, it is first drawn in by the negative pressure connecting pipe 12 and enters the cyclone separator 6 above it through the dust extraction pipe 1201. The cyclone separator 6 separates the plastic powder dust from the airflow and collects it in the collector at the bottom of the cyclone separator 6 for subsequent reuse. Some fine dust that cannot be collected by the cyclone separator 6 continues to enter the filter cartridge 7 through the first pipe 1202. Multiple filter cartridges inside the filter cartridge 7 filter and collect the dust. The dust that remains in the air is then driven by the fan to continue along the second pipe 1203 into the first humidification pipe 1204, the third pipe 1205, and the second humidification pipe 1206. It mixes with the sprayed water in the first humidification pipe 1204 and the second humidification pipe 1206 and falls into the collection box 8, thus completing the multi-stage purification and treatment of the dust.

[0037] Please see the appendix Figure 6 Appendix Figure 7 and attached Figure 8 The uniform infusion assembly includes a storage tank 15 and a rotating shaft 17. The storage tank 15 is fixed to the opposite side of the outer wall of the first humidification pipe 1204 and the second humidification pipe 1206 and is positioned above the collection tank 8. The rotating shaft 17 rotates on the inner wall of the third pipe 1205 and extends through it at one end. A housing 16 is fixed to the top of the storage tank 15. A bevel gear 20 and multiple drive blades 18 are fixed to the outer wall of the rotating shaft 17. A rotating rod 19 rotates on the inner wall of the housing 16. A bevel gear 20 that meshes with the bevel gear 20 is fixed to the outer wall of the rotating rod 19. A turntable 22 is fixed to the bottom of the rotating rod 19. An eccentric column 23 is fixed to the outer wall of the turntable 22. A collar 24 is slidably fitted on the outer wall of 23. A limiting component is provided on the outside of the collar 24 to restrict its movement. A connecting block 25 is fixed on the outer wall of the collar 24. One end of a connecting rod 26 is fixed on the outer wall of the connecting block 25. A sliding plate 27 is fixed on the other end of the connecting rod 26. The connecting block 25 is U-shaped. The connecting rod 26 slides through the inner walls of the storage box 15, the outer shell 16, and the first humidification pipe 1204. An isolation plate 28 and a spring 30 are provided on the inner wall of the storage box 15. A one-way valve 29 is installed through the inner wall of the isolation plate 28. A liquid outlet pipe 31 is passed through the bottom of the storage box 15 and is located above the collection box 8.

[0038] Specifically, the rotating shaft 17 and the drive blade 18 are located on the eccentric side of the pipe 1205. Part of the drive blade 18 is located inside the airflow channel, and part is located on the eccentric side, which facilitates the rotation of the rotating shaft 17 by the force difference on both sides. Since the pipe 1205 is enclosed, a continuous airflow is generated inside the pipe under the action of the fan. When the airflow passes through the drive blade 18, it will cause it to rotate, thereby causing the rotating shaft 17 to rotate. Then, by the meshing of the bevel gear 20 and bevel gear 21 fixed outside the rotating shaft 17, the rotating rod 19 is driven to rotate. The rotating rod 19 then drives the turntable 22 to rotate. After that, the turntable 22 will drive the eccentric column 23 fixed on the surface to rotate around the axis. The linkage of the limiting components converts the rotation of the turntable 22 into the reciprocating linear sliding of the collar 24 sleeved on the outer wall of the eccentric column 23. Then, the collar 24 drives the connecting block 25, connecting rod 26 and sliding plate 27 fixed thereto to slide back and forth synchronously. The sliding plate 27 slides in the storage box 15, which stores neutralizing liquid for neutralizing the acidity and alkalinity of the dust-water mixture and precipitating liquid to help the dust settle and separate. The liquid is extracted through the one-way valve 29 and pushed into the liquid outlet pipe 31 connected to the bottom, so that it is transported to the collection box 8 at the bottom. The gear and other components are protected by the outer shell 16. The U-shaped connecting block 25 is set to transmit the power of the eccentric column 23 to the sliding plate 27 below.

[0039] Please see the appendix Figure 7 and attached Figure 8 The limiting component includes multiple fixing blocks 32 fixed to the outer wall of the collar 24, and multiple limiting rods 33 fixed on the opposite side of the inner wall of the outer shell 16. The fixing blocks 32 slide on the outer wall of the limiting rods 33.

[0040] Specifically, multiple limiting rods 33 are fixed on one side of the inner wall of the outer casing 16, and fixing blocks 32 are fixed on both the left and right sides of the outer wall of the collar 24. The fixing blocks 32 slide on the outer wall of the limiting rods 33. When the collar 24 is driven to move by the eccentric column 23, it will be limited by the limiting rods 33 along with the fixing blocks 32, so that it always slides back and forth along the direction of the limiting rods 33, thereby converting the rotation into linear motion, and then driving the subsequent components to slide synchronously, so as to achieve the effect of intermittently extracting liquid.

[0041] Please see the appendix Figure 7 and attached Figure 8 The isolation plate 28 divides the storage box 15 into a liquid storage chamber and a liquid outlet chamber. The connecting rod 26 and the sliding plate 27 slide on the inner wall of the liquid outlet chamber. One end of the spring 30 is fixed to the inner wall of the liquid outlet chamber, and the other end of the spring 30 is fixed to the outer wall of the sliding plate 27. The one-way valve 29 is set between the liquid storage chamber and the liquid outlet chamber, and the liquid outlet pipe 31 runs through the inner wall of the liquid outlet chamber.

[0042] Specifically, the storage tank 15 is divided into a storage chamber and an outlet chamber by a partition plate 28. The storage chamber is on top and contains neutralizing liquid and precipitate, while the outlet chamber is on the bottom. The two are connected by a one-way valve 29 installed through the partition plate 28. The connecting block 25 drives the sliding plate 27 to slide back and forth in the outlet chamber via the connecting rod 26. When the sliding plate 27 moves to the right, the outlet chamber draws liquid from the storage chamber into the outlet chamber through the one-way valve 29. When the sliding plate 27 moves to the left, the outlet chamber discharges the drawn liquid into the collection tank 8 at the bottom through the outlet pipe 31, so that the liquid is discharged intermittently and automatically, which helps to save liquid usage and reduce costs.

[0043] Please see the appendix Figure 9 and attached Figure 10 The cleaning assembly includes a second rotating shaft 34 and a reciprocating screw 36. The second rotating shaft 34 rotates on the inner wall of the fourth pipe 1207 and extends out at one end. In addition, multiple drive blades 18 are evenly fixed on the outer wall of the second rotating shaft 34. The reciprocating screw 36 rotates on the opposite side of the inner wall of the collection box 8. A cleaning frame 37 is threadedly connected to the outer wall of the reciprocating screw 36. Multiple slide rods 38 are fixed on the opposite side of the inner wall of the collection box 8. The outer wall of the cleaning frame 37 is slidably connected to the inner wall of the collection box 8, and the inner wall of the cleaning frame 37 is slidably connected to the outer wall of the slide rods 38. A transmission assembly for transmitting power is provided between the second rotating shaft 34 and the reciprocating screw 36.

[0044] Specifically, the rotating shaft 34 also rotates on the eccentric side of the pipe 1207 to facilitate the reception of airflow. When the airflow passes through the pipe 1207, it drives the drive blade 18 installed on the rotating shaft 34 to rotate. The rotational power of the rotating shaft 34 is transmitted to the reciprocating screw 36 through the transmission assembly, causing the reciprocating screw 36 to rotate. This causes the outer wall of the reciprocating screw 36 to slide back and forth through the threaded cleaning frame 37, scraping against the inner wall of the collection box 8 to prevent dust and other particles from adhering to the inner wall, thus achieving an automatic cleaning effect. At the same time, it can also stir the mixture of dust and water, fully mixing and reacting the neutralizing liquid and other particles delivered in the uniform infusion assembly with the mixture, accelerating the reaction rate. Meanwhile, multiple sliding rods 38 are used to limit the sliding of the cleaning frame 37 to ensure its stable movement.

[0045] Please see the appendix Figure 9 and attached Figure 10 The transmission assembly includes a bevel gear 42 fixed to the outer wall of the rotating shaft 34 and a protective shell 35 fixed to the top of the collection box 8. A worm gear 39 rotates on the opposite side of the inner wall of the collection box 8 and the protective shell 35. A bevel gear 43 is fixed to the outer wall of the worm gear 39. A transmission column 40 and a rotating rod 45 rotate on the inner wall of the collection box 8. A worm wheel 41 and a small gear 44 are fixed to the outer wall of the transmission column 40. A large gear 46 is fixed to the outer wall of the rotating rod 45. The rotating rod 45 is fixedly connected to the reciprocating lead screw 36.

[0046] Specifically, the power of the rotating shaft 34 is gradually transmitted through the meshing of multiple gears, and the power is made controllable by the speed reduction transmission of the worm 39 and worm wheel 41, as well as the small gear 44 and large gear 46, thereby driving the rotating rod 45 to rotate and the reciprocating screw 36 fixedly connected to the rotating rod 45 to rotate, thus driving the cleaning component to operate.

[0047] Please see the appendix Figure 9 and attached Figure 10 The worm 39 and worm wheel 41 are connected by meshing teeth, the bevel gear 3 42 and bevel gear 43 are connected by meshing teeth, the pinion 44 and the gear 46 are connected by meshing teeth, and the protective shell 35 is disposed outside the bevel gear 3 42 and bevel gear 43.

[0048] Specifically, the protective housing 35 protects the meshing of multiple gears and isolates them from the outside world, preventing accidental damage to the device and providing stability.

[0049] Please see the appendix Figure 5 The spraying device includes a water tank 9 located above the collection box 8 and multiple spray heads 13 installed on the inner walls of the first humidification pipe 1204 and the second humidification pipe 1206. The inner wall of the water tank 9 is provided with a water storage 14, and the water tank 9 and the spray heads 13 are connected to each other for spraying out the stored water 14.

[0050] Specifically, the water tank 9 contains a large amount of stored water 14, which is connected to the spray head 13. When dust passes through, the spray head 13 sprays water to mix with the dust, thereby capturing it and causing it to fall into the collection box 8 at the bottom for collection, achieving a thorough purification effect.

[0051] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 The traction device 2 causes the gas cylinder body 3 to be conveyed along the length extension direction of the spray chamber 4 while rotating the gas cylinder body 3 in the horizontal plane. The bottom end of the spray chamber 4 is provided with an inclined collection groove, and the connecting pipe 12 is installed through the inner wall of the inclined collection groove. Multiple filter elements are installed inside the filter element filter 7. The bottom end of the filter element is provided with a dust collection cart 47 for collecting dust. The fan 2 11 is located directly above the multiple filter elements.

[0052] Specifically, the traction device 2 moves the gas cylinder body 3 along the suspension chain 1 inside the spray booth 4 to complete the spraying work. The dust generated by the spraying will slide along the inclined surface of the collection groove at the bottom of the spray booth 4 and be collected to the bottom, making it convenient for the connecting pipe 12 to extract the dust. The second fan 11 is set at the top inside the filter element 7, which sucks up the dust and filters it through multiple filter elements inside. After the dust is collected, it will fall into the dust collection cart 47 set directly below for further processing, thus completing the dust collection work during the purification process and preventing it from polluting the environment.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
