Abstract
Description
Technical Field
[0001] This invention relates to the field of metal parts processing technology, specifically to a metal parts powder dust recovery system and recovery device. Background Technology
[0002] The dust recovery device for metal parts powder coating mainly consists of a powder coating chamber, a large cyclone separator, a bag filter, an induced draft fan, a powder collection mechanism, and a control system. The device uses negative pressure to draw oversprayed powder into the pipeline, where most of the powder is separated by the large cyclone separator, and the exhaust gas is then finely filtered by a filter cartridge. The recovered powder can be recycled. The system is equipped with pulse cleaning, variable frequency speed control, and an explosion-proof safety structure. Its operation is centrally controlled by a PLC, achieving efficient powder recovery, purified emissions, and automated operation.
[0003] In existing metal component dust recovery devices, the large cyclone separator condenses inside the unit when used in low-temperature, high-humidity environments, causing powder to clump together. In high-temperature environments, the high internal temperature of the cyclone separator softens and makes the powder sticky, causing it to adhere to the inner wall and accumulate, forming arched blockages. Therefore, blockages occur regardless of temperature, requiring shutdown for unblocking and resulting in reduced dust recovery efficiency. Summary of the Invention

A discharge valve 11 is fixedly connected to the bottom of the large cyclone separator 2. The discharge valve 11 can control the discharge rate.
[0020] The temperature regulating mechanism 3 includes a base 301, which provides an installation position. The base 301 is externally fixedly connected to the bottom of the mounting bracket 1. A liquid tank 302 is fixedly connected to the top of the base 301, which can hold liquid. Heat dissipation fins 303 are fixedly connected to the outside of the liquid tank 302, which can dissipate heat from the liquid inside the liquid tank 302 through heat conduction. A mounting box 304 is fixedly connected to the bottom of the inside of the liquid tank 302, providing installation space. An impeller 305 is rotatably connected inside the mounting box 304, which can rotate under the action of liquid flow. A rotating shaft 306 is fixedly connected to the middle of the impeller 305, which can transmit the rotational force. Two agitator blades 307 are fixedly connected to the outside of the rotating shaft 306. The rotating shaft 306 drives the agitator blades 307 to rotate, agitating the liquid inside the liquid tank 302 and accelerating heat dissipation. A heating wire 308 is fixedly connected to the top of the liquid tank 302. The top of the heating wire 308 is installed on the top of the liquid tank 302, and the bottom of the heating wire 308 is located at the bottom of the inside of the liquid tank 302. Therefore, when the liquid level inside the liquid tank 302 drops, it can also heat the liquid inside the liquid tank 302. A liquid-passing pipe 309 is fixedly connected to the outside of the mounting box 304, serving a connecting function. A water pump 310 is installed outside the base 301, providing power for the flow of the liquid. A liquid outlet pipe 311 is fixedly connected to the output end of pump 310, and an automatic valve 312 is fixedly connected to the input end of pump 310. A liquid extraction valve 313 is fixedly connected to the top of the automatic valve 312. The end of the liquid extraction valve 313 away from pump 310 is fixedly connected to the bottom of the liquid tank 302. A jacket 314 is fixedly connected to the outside of the large cyclone separator 2. The jacket 314 can form a sealed space outside the large cyclone separator 2, allowing liquid to pass through. The end of the liquid outlet pipe 311 away from pump 310 is detachably connected to the bottom of the jacket 314. A drain pipe 315 is detachably connected to the top of the jacket 314.

A liquid injection pipe 316 is fixedly connected to the top of the liquid tank 302, and a sealing cap is threaded onto the top of the liquid injection pipe 316. The top of the rotating shaft 306 is rotatably connected to the top of the liquid tank 302, and the outer bottom end of the rotating shaft 306 is rotatably connected to the top of the mounting box 304. When heating the large cyclone separator 2, the heating wire 308 is first started. After the heating wire 308 is started, it heats the liquid inside the liquid tank 302. When the liquid inside the liquid tank 302 is warm, the water pump 310 is started. At this time, the warm liquid in the liquid tank 302 is drawn out through the liquid extraction valve 313 and introduced into the interior of the jacket 314 through the liquid outlet pipe 311. When the interior of the jacket 314 is filled with warm liquid...The liquid then re-enters the liquid tank 302 through the drain pipe 315, where it is reheated. This continuous circulation of warm liquid continuously heats the outer wall of the large cyclone separator 2, preventing condensation inside the separator 2 due to low temperatures in high-humidity environments, and further preventing powder from clumping due to condensation.
[0021] The auxiliary heat dissipation mechanism 4 includes a fixing ring 401, which provides an installation position and space for liquid flow. The fixing ring 401 is externally fixedly connected to the bottom of the base 301. A rotating ring 402 is rotatably connected to the inner side of the fixing ring 401. Multiple blades 403 are fixedly connected to the outer wall of the rotating ring 402. The rotating ring 402, in conjunction with the blades 403, can rotate under the flow of liquid. A mounting plate 404 is fixedly connected to the inner side of the rotating ring 402. After the rotating ring 402 rotates, it drives the mounting plate 404 to rotate. A connecting shaft 405 is fixedly connected to the top of the mounting plate 404. A mounting frame 406 is fixedly connected to the middle of the base 301, which provides an installation position. A fan 407 is rotatably connected to the inner side of the mounting frame 406. After the mounting plate 404 rotates, it rotates through the connecting shaft 405. 5 drives the fan 407 to rotate, thereby generating wind power. The top of the connecting shaft 405 is fixedly connected to the middle of the fan 407. Multiple jet nozzles 408 are fixedly connected to the top of the outer side of the base 301. The jet nozzles 408 can guide the angle of the airflow. Multiple air inlets 409 are opened on the outside of the base 301, allowing air to enter. The end of the automatic valve 312 away from the water pump 310 is fixedly connected to the solenoid valve 410. The solenoid valve 410 can control the opening and closing of the liquid flow path. The end of the solenoid valve 410 away from the automatic valve 312 is fixedly connected to the liquid suction pipe 411, which serves as a connection. The end of the liquid suction pipe 411 away from the water pump 310 is fixedly connected to the outside of the fixing ring 401. The bottom of the liquid passage pipe 309 is fixedly connected to the outside of the fixing ring 401. When cooling the large cyclone separator 2, first start the water pump 310, close the automatic valve 312, and open the solenoid valve 410. At this time, the output end of the water pump 310 generates suction, which is transmitted to the liquid extraction pipe 411, and then through the fixed ring 401 and the liquid passage pipe 309 to the inside of the mounting box 304. At this time, the liquid inside the liquid tank 302 will enter the inside of the mounting box 304, and the flow of the liquid will drive the impeller 305 to rotate, thereby driving the rotating shaft 306 to rotate. The rotation of the rotating shaft 306 drives the agitator 307 to rotate, and the rotation of the agitator 307 can agitate the liquid inside the liquid tank 302, thereby accelerating the heat dissipation of the liquid inside the liquid tank 302. When the liquid in the mounting box 304 enters the inside of the fixed ring 401 through the liquid passage pipe 309, it can drive the blade 403 to rotate. The rotation of the blade 403 drives the rotating ring 402 to rotate, and the rotation of the rotating ring 402 drives the mounting plate 404 to rotate. The rotation of the mounting plate 404 drives the connecting shaft 405 to rotate, which in turn drives the fan 407 to rotate. After the fan 407 rotates, it draws in air through the air inlet 409 and discharges it through the nozzle 408, thus spraying the gas onto the outside of the liquid tank 302 and the heat dissipation fins 303. The heat conduction of the heat dissipation fins 303 further cools the liquid inside the liquid tank 302. At this time, the liquid enters the outlet pipe 311 through the suction pipe 411 and the solenoid valve 410, and then enters the jacket 314 to cool the outer wall of the large cyclone separator 2. Since the powder used for spraying is a thermosetting powder coating, and the temperature is high in summer, the temperature inside the large cyclone separator 2 will rise, which will cause the powder to soften and become sticky. Cooling the outer wall of the large cyclone separator 2 at this time can prevent the powder from softening and becoming sticky, thereby avoiding the accumulation of powder in the cone of the large cyclone separator 2 to form an arch bridge, thus preventing the large cyclone separator 2 from becoming blocked.
[0022] The auxiliary feeding mechanism 5 includes a fixed cylinder 501, which provides an installation position. The fixed cylinder 501 is externally fixedly connected to the top of the liquid tank 302. A movable inner rod 502 is slidably connected inside the fixed cylinder 501, providing the installation position. A tension spring 503 is installed inside the fixed cylinder 501, which can pull the movable inner rod 502 to reset. A rack 504 is externally fixedly connected to the movable inner rod 502. A striking crank 505 is fixedly connected to the end of the movable inner rod 502 away from the tension spring 503. The striking crank 505 is connected to the movable inner rod 502. A stabilizing device is externally fixedly connected to the striking crank 505. A fixed sliding rod 506 is provided to increase the stability of the striking crank 505 during movement. A fixed limiting sleeve 507 is fixedly connected to the bottom of the middle part of the mounting bracket 1. The fixed limiting sleeve 507 can maintain the stability of the bottom movement of the striking crank 505. The bottom of the striking crank 505 is slidably connected inside the fixed limiting sleeve 507. A sector gear 514 is fixedly connected to the top of the rotating shaft 306. The rotation of the sector gear 514 can drive the rack 504 to move. The sector gear 514 and the rack 504 are meshed. Multiple fixing seats 508 are fixedly connected to the inner side of the middle part of the mounting bracket 1. The fixing seats 508 provide a mounting base. The mounting base 508 has a sliding connection to a limiting plate 509. Each of the four corners of the limiting plate 509 has a liquid passage hole 510, which reduces the liquid flow rate and thus decreases the efficiency of the limiting plate 509's movement. The mounting base 508 has a reset buffer spring 511 inside. A connecting post 512 is fixedly connected to the end of the limiting plate 509 away from the reset buffer spring 511, serving as a connection. A connecting plate 513 is fixedly connected to the end of the connecting post 512 away from the limiting plate 509. The connecting plate 513 can be mounted on the clamp 314, allowing the connecting post 512 to be installed. The side of 513 away from the connecting column 512 is fixedly connected to the outer bottom end of the jacket 314. The outer side of the rack 504 is slidably connected to the outer wall of the fixed cylinder 501. The outer side of the stabilizing sliding rod 506 is slidably connected to the inside of the mounting bracket 1. The outer bottom end of the large cyclone separator 2 is fixedly connected to the striking plate 515. One end of the tension spring 503 is fixedly connected to the inside of the fixed cylinder 501. The other end of the tension spring 503 is fixedly connected to the inside of the movable inner rod 502. One end of the reset buffer spring 511 is fixedly connected to the inside of the fixed seat 508. The other end of the reset buffer spring 511 is fixedly connected to the side of the limiting plate 509 away from the connecting column 512. When the rotating shaft 306 rotates, it drives the sector gear 514 to rotate. The rotation of the sector gear 514 drives the rack 504 to move away from the tension spring 503, thereby driving the movable inner rod 502 to move away from the tension spring 503, thus stretching the tension spring 503. At the same time, it drives the striking crank 505 to move away from the large cyclone separator 2. When the sector gear 514 rotates to the toothless side, under the tension of the tension spring 503, it drives the movable inner rod 502 to move towards the tension spring 503. At this time, it drives the striking crank 505 to move towards the large cyclone separator 2, and the bottom of the striking crank 505 strikes the outside of the striking plate 515, thereby generating vibration. The force of the vibration then uses the force to dislodge the powder accumulated at the bottom cone of the large cyclone separator 2. The vibration force will then disperse and be discharged through the discharge valve 11. When the vibration force is transmitted to the connecting plate 513, it can move the connecting column 512 towards the fixed seat 508 and drive the limiting plate 509 towards the reset buffer spring 511, thereby compressing the reset buffer spring 511. The elasticity of the reset buffer spring 511 buffers the impact force during vibration. Since the interior of the fixed seat 508 is filled with liquid and the hole area of the liquid passage 510 is limited, the amount of liquid passing through is limited. Therefore, the speed at which the limiting plate 509 moves towards the connecting plate 513 under the action of the reaction force of the reset buffer spring 511 will be slowed down. This can prevent the elastic force of the reset buffer spring 511 from strengthening the vibration. Therefore, the vibration on the large cyclone separator 2 will not be weakened, but the vibration force transmitted to the mounting bracket 1 will be weakened. At this time, the vibration force is prevented from being transmitted to the ground, protecting the device and the ground.
[0023] A dust recovery system for metal parts powder spraying includes an exhaust fan 12, an exhaust fan 13, and a control module 14. The powder spraying chamber 6 is connected to a large cyclone separator 2, the large cyclone separator 2 is connected to a bag filter 7, the bag filter 7 is connected to the exhaust fan 12, and the exhaust fan 12 is connected to the exhaust fan 13. The exhaust fan 12 is used to generate negative pressure to draw dust into the bag filter 7. The exhaust fan 12 is connected to the control module 14, which is used to control the opening and closing of the exhaust fan 12 and the water pump 310. The control module 14 is connected to the water pump 310.
[0024] Working principle: When heating the large cyclone separator 2, the heating wire 308 is first started. After the heating wire 308 is started, it heats the liquid inside the liquid tank 302. When the liquid inside the liquid tank 302 is warm, the water pump 310 is started, and the automatic valve 312 is opened and the solenoid valve 410 is closed. At this time, the warm liquid in the liquid tank 302 is drawn out through the liquid extraction valve 313 and passed into the jacket 314 through the liquid outlet pipe 311. When the jacket 314 is full of warm liquid, the liquid will re-enter the liquid tank 302 through the liquid outlet pipe 315 for reheating. This continuous circulation of warm liquid continuously heats the outer wall of the large cyclone separator 2, thus preventing condensation inside the large cyclone separator 2 due to low temperature in high humidity environments, and further preventing powder from clumping due to condensation. When cooling the large cyclone separator 2, first start the water pump 310, close the automatic valve 312, and open the solenoid valve 410. At this time, the output end of the water pump 310 generates suction, which is transmitted to the liquid extraction pipe 411, and then through the fixed ring 401 and the liquid passage pipe 309 to the inside of the mounting box 304. At this time, the liquid inside the liquid tank 302 will enter the inside of the mounting box 304, and the flow of the liquid will drive the impeller 305 to rotate, thereby driving the rotating shaft 306 to rotate. The rotation of the rotating shaft 306 drives the agitator 307 to rotate, and the rotation of the agitator 307 can agitate the liquid inside the liquid tank 302, thereby accelerating the heat dissipation of the liquid inside the liquid tank 302. When the liquid in the mounting box 304 enters the inside of the fixed ring 401 through the liquid passage pipe 309, it can drive the blade 403 to rotate. The rotation of the blade 403 drives the rotating ring 402 to rotate, and the rotation of the rotating ring 402 drives the mounting plate 404 to rotate. The rotation of the mounting plate 404 drives the connecting shaft 405 to rotate, which in turn drives the fan 407 to rotate. After the fan 407 rotates, it draws in air through the air inlet 409 and discharges it through the nozzle 408, thus spraying the gas onto the outside of the liquid tank 302 and the heat dissipation fins 303. The heat conduction of the heat dissipation fins 303 further cools the liquid inside the liquid tank 302. At this time, the liquid enters the outlet pipe 311 through the suction pipe 411 and the solenoid valve 410 and then enters the jacket 314 to cool the outer wall of the large cyclone separator 2. Since the powder used for spraying is a thermosetting powder coating, and the temperature is high in summer, the temperature inside the large cyclone separator 2 will rise, which will cause the powder to soften and become sticky. Cooling the outer wall of the large cyclone separator 2 at this time can prevent the powder from softening and becoming sticky, thereby avoiding the accumulation of powder in the cone of the large cyclone separator 2 to form an arch bridge, thus preventing the large cyclone separator 2 from becoming blocked. When the rotating shaft 306 rotates, it drives the sector gear 514 to rotate. The rotation of the sector gear 514 drives the rack 504 to move away from the tension spring 503, thereby driving the movable inner rod 502 to move away from the tension spring 503, thus stretching the tension spring 503. At the same time, it drives the striking crank 505 to move away from the large cyclone separator 2. When the sector gear 514 rotates to the toothless side, under the tension of the tension spring 503, it drives the movable inner rod 502 to move towards the tension spring 503. At this time, it drives the striking crank 505 to move towards the large cyclone separator 2, and the bottom of the striking crank 505 strikes the outside of the striking plate 515, thereby generating vibration. The force of the vibration then uses the force to dislodge the powder accumulated at the bottom cone of the large cyclone separator 2. The vibration force will then disperse and be discharged through the discharge valve 11. When the vibration force is transmitted to the connecting plate 513, it can move the connecting column 512 towards the fixed seat 508 and drive the limiting plate 509 towards the reset buffer spring 511, thereby compressing the reset buffer spring 511. The elasticity of the reset buffer spring 511 buffers the impact force during vibration. Since the interior of the fixed seat 508 is filled with liquid and the hole area of the liquid passage 510 is limited, the amount of liquid passing through is limited. Therefore, the speed at which the limiting plate 509 moves towards the connecting plate 513 under the action of the reaction force of the reset buffer spring 511 will be slowed down. This can prevent the elastic force of the reset buffer spring 511 from strengthening the vibration. Therefore, the vibration on the large cyclone separator 2 will not be weakened, but the vibration force transmitted to the mounting bracket 1 will be weakened. At this time, the vibration force is prevented from being transmitted to the ground, protecting the device and the ground.
