Description

Technical Field

[0001] The present invention relates to the technical field of crack detection, and particularly to a lip brick crack detection device and method for photovoltaic glass. Background Art

[0002] The lip brick is located at the discharge port of the glass furnace and is a key component for guiding the high-temperature glass liquid to the forming equipment. The performance and quality of the lip brick are directly related to the flow state of the glass liquid and the forming quality, and thus affect the final quality of the photovoltaic glass.

[0003] A patent with the publication number CN115452854A discloses a lip brick crack detection device and method. After applying a penetrant to the outer wall of the lip brick through a coating component, a developer is sprayed onto the outer wall of the lip brick through a spray nozzle. The developer will attract the penetrant in the cracks. Under a certain light source, the traces of the penetrant at the cracks are displayed, so as to detect the morphology and distribution state of the cracks. And before the lip brick is detected, a grinding belt a moves along the outside of the connecting block a, and a grinding belt b moves along the outside of the connecting block b, so as to perform a fitting grinding on the outer wall of the lip brick to remove the impurities on the surface of the lip brick; Since the lip brick goes through multiple processes in the production workshop, dust in the workshop environment and brick chips generated during the processing will adhere to its surface. And during the production process of the lip brick, in order to facilitate the separation of the mold from the brick blank, a release agent is usually used. After the lip brick is demolded, a small amount of release agent will remain on the surface, resulting in a thin oily or powdery residue left on the surface of the lip brick; Therefore, when the above device grinds the lip brick, the ground dust will enter the cracks of the lip brick under the action of the grinding belt a and the grinding belt b, and the dust will be compacted in the cracks, resulting in the penetrant being unable to penetrate into the cracks of the lip brick, and thus the morphology and distribution of the cracks cannot be accurately detected.

[0014] To achieve the above object, the present invention provides the following technical solution: A detection method for a lip brick crack detection device for photovoltaic glass, including the following steps: First, place the lip brick to be detected on the conveyor line, and then the conveyor line transports the lip brick to the area position of the grinding unit, and the double-output shaft motor drives the grinding disc to grind the lip brick; Meanwhile, the first output shaft of the double-output shaft motor drives the rotating rod to rotate, causing the sliding shaft to slide along the corrugated groove. During the sliding process of the sliding shaft, the linear frame makes a reciprocating linear motion in the sliding cylinder, so that the piston makes a linear reciprocating motion in the air cylinder. At this time, the gas outside the air cylinder enters the air cylinder through the first one-way valve, and then the gas in the air cylinder enters the upper cavity of the pressure box through the second one-way valve under the action of the piston; As the gas pressure in the upper cavity of the pressure box increases, the lifting plate starts to shift towards the lower cavity under the action of the gas pressure. Until the lifting plate shifts to an appropriate position, the compressed gas in the upper cavity enters the rotating groove through the air pipe, and then the compressed gas in the rotating groove is ejected from the opening at the end of the spray pipe far away from the rotating shaft; Utilize the fact that the flow path of the compressed gas entering the spray pipe in the rotating groove decreases, resulting in the acceleration of the gas flow rate after passing through the spray pipe, and then the high-speed air flow ejected from the spray pipe will scour the surface of the lip brick during the grinding process; After the lip brick is polished, the conveyor line transports the polished lip brick to the area position of the coating unit. Then, the drainage ball contacts the surface of the lip brick to be coated. At the same time, the lip brick presses the drainage ball and the telescopic rod to slide along the limiting rod. Then, the drainage ball no longer blocks the water outlet hole, and the permeating liquid in the storage box can be discharged through the water outlet hole; When the lip brick is displaced, the drainage ball rotates under the action of the lip brick. The rotation of the drainage ball guides the permeating liquid in the storage box to be discharged from the water outlet hole, so that the permeating liquid is coated on the surface of the curved surface of the lip brick to be detected; The lip brick coated with the permeating liquid needs to be left standing for a period of time to allow the permeating liquid to fully penetrate into the pores or cracks of the lip brick. Then, manually wipe off the excess permeating liquid on the surface of the curved surface to be detected with a cleaning cloth, manually spray a developer onto the area to be detected of the lip brick, and finally place the lip brick to be detected in an appropriate environment. Irradiate the area to be detected of the lip brick with an ultraviolet lamp to observe the cracks in the area to be detected of the lip brick; When the double-output shaft motor is running, the second output shaft on it drives the fan to rotate. The rotation of the fan guides the surrounding gas to flow towards the collecting cylinder. Then, the gas in the dust collecting hood area is subjected to the traction force when the fan rotates, and the flying dust particles will follow the fluid and enter the air collecting box from the dust collecting hood, and finally enter the collecting cylinder from the air collecting box; When the fan rotates, the centrifugal tube and the drainage plate outside the centrifugal tube will also rotate synchronously. The dust particles in the fluid will contact the surface of the drainage plate and the inner wall of the filter cylinder. At this time, the water body in the centrifugal chamber enters the drainage chamber under the action of centrifugal force, and the water body in the drainage chamber is discharged from the drainage hole under the action of centrifugal force. At this time, there is a water film attached to the surface of the drainage plate. When the fluid passes through the collecting cylinder, the dust particles in the fluid will be adsorbed by the water body; The sewage is generated after the dust particles contact and mix with the water body. The sewage will gather at the bottom of the collecting cylinder and flow onto the guide plate, and then enter the filter cylinder through the guide plate. The sewage entering the filter cylinder will first pass through the filter plate, and the dust particles or particulate matters in the sewage will be intercepted by the filter plate. After the water body passes through the filter plate, it will mix with the water body at the bottom of the filter cylinder; When the water body in the water tank gradually drains out from the drainage hole, the pressure inside the water tank decreases, causing the water body inside the filter cylinder to enter the water tank through the return pipe under the action of negative pressure.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting a grinding unit to grind the lip bricks, arranging air spray pipes in an array outside the rotating shaft, and using a double-output shaft motor to drive the rotating rod to rotate, the piston is made to transport the gas in the air cylinder to the pressure box. Under the action of the pressure box and the air spray pipes, high-speed gas flushes the surface of the ground lip bricks, thus preventing dust from clogging in the cracks, improving the penetration effect of the penetrant, and further enhancing the detection accuracy of the morphology and distribution of cracks on the lip brick surface. 2. Since the flushing of the air spray pipes will cause dust to fly, and the flying dust will eventually settle on the lip brick surface, affecting the penetration effect of the penetrant. By setting a gas collection box and a dust collection hood, and installing a fan in the gas collection box, the dust is guided into the gas collection box, thus preventing the flying dust from adhering to the lip brick surface, ensuring the penetration effect of the penetrant, and further improving the detection accuracy of the cracks. 3. By setting a collection cylinder and arranging a drainage plate in the collection cylinder, the water body is discharged by the drainage plate using centrifugal force, enabling the water body to capture the dust, preventing the dust from flying, and improving the detection environment of the lip bricks. 4. By setting a return pipe, a filter cylinder, and a filter plate in the filter cylinder, the water body mixed with dust is collected, filtered, and then re-enters the water tank through the return pipe for continued use, improving the utilization rate of the water body.

The gas outside the air cylinder 56 can enter the inside of the air cylinder 56 through the check valve one. The air cylinder 56 is arranged at the end of the sliding cylinder 52 away from the double-output shaft motor 13. The end of the air cylinder 56 away from the sliding cylinder 52 is connected to the pressure box 51. And a check valve two is arranged at the connection between the air cylinder 56 and the pressure box 51, so that the gas can only enter the pressure box 51 from the air cylinder 56 through the check valve two.

When the lifting plate 57 is displaced to an appropriate position, the upper cavity in the pressure box 51 will communicate with the rotating groove 24.

[0033] The coating unit 12 includes a fixing plate 14. A storage box 15 is arranged at the lower end of the fixing plate 14. A storage tank 16 is arranged at the upper end of the fixing plate 14. The storage tank 16 communicates with the inside of the storage box 15. The storage box 15 is mutually adapted to the contour of the surface to be coated of the lip brick. A row of liquid discharge balls 17 is arranged on the surface of the storage box 15 away from the fixing plate 14. The fixing plate 14 is connected to the conveying line 1. Penetrating liquid is poured into both the storage tank 16 and the storage box 15. The penetrating liquid in the storage tank 16 can enter the storage box 15 under the action of gravity; Water outlet holes are arranged in an array on the storage box 15.

Initially, under the reset elastic force of the second spring, the liquid discharge balls 17 block the water outlet holes.

[0034] During the use process, first start the double-output shaft motor 13 and the conveyor line 1, then place the lip bricks to be detected on the conveyor line 1, and then the conveyor line transports the lip bricks. The rotating rollers on both sides of the lip bricks limit the lip bricks during the transportation process. When the lip bricks are transported to the grinding unit 2, at this time, under the elastic force of the elastic piece, the grinding piece 23 contacts the surface to be ground of the lip bricks, and at this time, the grinding piece 23 applies an appropriate amount of pressure to the lip bricks; At the same time, the first output shaft of the double-output shaft motor 13 rotates and drives the first synchronous wheel 131 to rotate synchronously. Under the action of the synchronous belt, the rotation of the first synchronous wheel 131 drives the second synchronous wheel 132 to rotate, causing the second synchronous wheel 132 to drive the rotating shaft 21 to rotate on the frame body 11 at this time. The rotation of the rotating shaft 21 causes the grinding piece 23 to grind the surface to be detected of the lip bricks, removing the dirt on the surface of the surface to be detected of the lip bricks; In addition, when the first output shaft of the double-output shaft motor 13 rotates, the rotating rod 53 will rotate synchronously with the first output shaft. The rotation of the rotating rod 53 causes the sliding shaft 55 to slide periodically along the corrugated groove 531. During the sliding process of the sliding shaft 55, the linear frame 54 will perform a reciprocating linear motion in the sliding cylinder 52, and then through the connecting rod, the piston 561 will perform a linear reciprocating motion in the air cylinder 56. At this time, the gas outside the air cylinder 56 enters the air cylinder 56 through the first one-way valve, and then the gas in the air cylinder 56 enters the upper cavity of the pressure box 51 through the second one-way valve under the action of the piston 561; As the gas continuously enters the upper cavity of the pressure box 51, the gas pressure inside the upper cavity of the pressure box 51 increases. The lifting plate 57 starts to shift towards the lower cavity under the action of the gas pressure, and the first spring deforms. When the lifting plate 57 shifts to an appropriate position, at this time, the compressed gas inside the upper cavity will enter the rotating groove 24 through the air pipe, and then the compressed gas in the rotating groove 24 is ejected from the opening at the end of the spray pipe 25 far from the rotating shaft 21. Since the flow path of the compressed gas entering the spray pipe 25 from the rotating groove 24 decreases, the flow rate of the gas will further increase after passing through the spray pipe 25, and then the high-speed air flow ejected from the spray pipe 25 will scour the surface of the lip bricks during the grinding process; When the lip bricks are ground, the conveyor line 1 transports the ground lip bricks to the area position of the coating unit 12. When the lip bricks contact the coating unit 12, the drainage ball 17 will contact the surface to be coated of the lip bricks. At the same time, the lip bricks will press the drainage ball 17 and the telescopic rod to slide along the limiting rod. At this time, the second spring deforms, and the drainage ball 17 no longer blocks the water outlet hole, and the permeating liquid in the storage box 15 can be discharged through the water outlet hole; When the lip bricks are displaced under the action of the conveyor line 1, the drainage ball 17 rotates under the action of the lip bricks. The rotation of the drainage ball 17 guides the permeating liquid in the storage box 15 to be discharged from the water outlet hole, causing the permeating liquid to be coated on the surface of the surface to be detected of the lip bricks; The lip brick coated with the penetrant needs to be left standing for a period of time so that the penetrant can fully penetrate into the pores or cracks of the lip brick. Then, the excess penetrant on the surface of the curved surface to be detected is manually wiped off with a cleaning cloth. Next, the developer is manually sprayed onto the area to be detected of the lip brick. Finally, the lip brick to be detected is placed in an appropriate environment, and the area to be detected of the lip brick is irradiated with an ultraviolet lamp, so as to observe the cracks in the area to be detected of the lip brick.

[0035] Example 2, refer to Figures 1 - 9 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is: The dust removal unit 3 includes a dust collection hood 31. The dust collection hood 31 is arranged in the upper region directly above the grinding unit 2. An air collection box 32 is arranged on the frame body 11. The dust collection hood 31 communicates with the inside of the air collection box 32. A fan 33 is arranged in the air collection box 32. The fan 33 is sleeved on the second output shaft of the double-output shaft motor 13. The fan 33 can rotate synchronously with the second output shaft of the double-output shaft motor 13. The dust collection hood 31 is arranged on the frame body 11, and one end of the dust collection hood 31 far away from the grinding unit 2 penetrates through the frame body 11.

[0036] The adsorption unit 4 includes a collection cylinder 41. The collection cylinder 41 is arranged at one end of the air collection box 32 far away from the double-output shaft motor 13. The collection cylinder 41 communicates with the inside of the air collection box 32. The gas inside the air collection box 32 can enter the collection cylinder 41, and finally the fluid can be discharged from one end of the collection cylinder 41 far away from the air collection box 32. A centrifugal tube 42 is arranged in the collection cylinder 41. The centrifugal tube 42 is coaxially connected with the second output shaft of the double-output shaft motor 13. Drainage plates 43 are arranged in an array on the outer side of the centrifugal tube 42. A centrifugal cavity is formed inside the centrifugal tube 42. Drainage cavities are formed inside the drainage plates 43. Drainage holes are arranged in an array on the drainage plates 43. The aperture of the drainage holes is small, and the water body can only penetrate out of the drainage holes under the action of centrifugal force. The drainage holes communicate with the inside of the drainage cavities, and the centrifugal cavity communicates with the inside of the drainage cavities.

[0037] During the use process, when the double-output shaft motor 13 drives the grinding unit 2 to grind the surface of the lip brick, the high-speed fluid is discharged through the air injection pipe 25 and flushes the dust on the surface of the lip brick. At this time, the dust particles generated by grinding on the lip brick will be affected by the fluid and fly; When the double-output shaft motor 13 is running, the second output shaft thereon will drive the fan 33 to rotate. The rotation of the fan 33 will guide the surrounding gas to flow towards the direction of the collection cylinder 41. Then, the gas at the dust collection hood 31 area will be affected by the traction force when the fan 33 rotates; Then, the flying dust particles will follow the fluid and enter the air collection box 32 from the dust collection hood 31, and finally enter the collection cylinder 41 from the air collection box 32.

A flow guide plate 45 is provided on the filter cylinder 44. A water tank 46 is provided on the flow guide plate 45. A return pipe 47 is provided on the water tank 46. One end of the return pipe 47 away from the water tank 46 extends to the bottom area position of the filter cylinder 44. A filter plate 48 is provided in the middle area of the filter cylinder 44. The filter plate 48 is preferably made of fiberglass. The flow guide plate 45 is provided at the opening of the collection cylinder 41 away from the air collection box 32. The return pipe 47 penetrates through the filter plate 48; The water tank 46 is filled with water. The centrifuge tube 42 is connected to the water tank 46 through a fixed pipe. The connection position of the fixed pipe and the water tank 46 is located in the area below the water level surface inside the water tank 46. The water in the water tank 46 can enter the centrifuge chamber through the fixed pipe. One end of the fixed pipe away from the water tank 46 is rotatably connected to the centrifuge tube 42. The connection position of the return pipe 47 and the water tank 46 is located in the area above the water level surface inside the water tank 46; The filter cylinder 44 is filled with an appropriate amount of water. The open end of one end of the return pipe 47 away from the water tank 46 is immersed in the water inside the filter cylinder 44.

[0040] During the use process, when the second output shaft of the double-output shaft motor 13 rotates, the dust particles generated by grinding on the lip brick will follow the fluid into the air collection box 32, and then enter the collection cylinder 41 from the air collection box 32; When the fan 33 rotates, the centrifuge tube 42 and the drainage plate 43 outside the centrifuge tube 42 will also rotate synchronously. When the dust particles follow the fluid through the collection cylinder 41, the dust particles in the fluid will contact the surface of the drainage plate 43 and the inner wall of the filter cylinder 44. During the rotation of the centrifuge tube 42 and the drainage plate 43, the water in the water tank 46 first enters the centrifuge chamber and the drainage chamber under the action of gravity. When the centrifuge tube 42 and the drainage plate 43 rotate, the water in the centrifuge chamber enters the drainage chamber under the action of centrifugal force, and the water in the drainage chamber is discharged from the liquid discharge hole under the action of centrifugal force. At this time, a water film adheres to the surface of the drainage plate 43. When the fluid passes through the collection cylinder 41, the dust particles in the fluid will be adsorbed by the water when they contact the drainage plate 43; After the dust particles contact and mix with the water, sewage is generated. The sewage on the surface of the drainage plate 43 gradually detaches from the drainage plate 43 under the action of centrifugal force and is blocked by the collection cylinder 41. Finally, the sewage gathers at the bottom of the collection cylinder 41 and flows onto the flow guide plate 45, and then enters the filter cylinder 44 through the flow guide plate 45. The sewage entering the filter cylinder 44 will first pass through the filter plate 48. The dust particles or particulate matters in the sewage will be intercepted by the filter plate 48. After the water passes through the filter plate 48, it will mix with the water at the bottom of the filter cylinder 44; When the water in the water tank 46 gradually drains out through the liquid discharge holes, the pressure inside the water tank 46 decreases, causing the water inside the filter cartridge 44 to enter the water tank 46 through the return pipe 47 under the action of negative pressure.

[0041] The remaining structure is the same as that of the second embodiment.

[0042] Embodiment 4, referring to Figures 1 - 10 , is the fourth embodiment of the present invention, providing: a detection method for a lip brick crack detection device for photovoltaic glass, including the following steps, S1. First, place the lip brick to be detected on the conveyor line 1, and then the conveyor line 1 transports the lip brick to the area position of the grinding unit 2. The double-output shaft motor 13 drives the grinding disc 23 to grind the lip brick. S2. At the same time, the first output shaft of the double-output shaft motor 13 drives the rotating rod 53 to rotate, causing the sliding shaft 55 to slide along the corrugated groove 531. During the sliding process of the sliding shaft 55, the linear frame 54 makes a reciprocating linear motion in the sliding cylinder 52, so that the piston 561 makes a linear reciprocating motion in the air cylinder 56. At this time, the gas outside the air cylinder 56 enters the air cylinder 56 through the one-way valve I, and then the gas in the air cylinder 56 enters the upper cavity of the pressure box 51 through the one-way valve II under the action of the piston 561. S3. As the gas pressure in the upper cavity of the pressure box 51 increases, the lifting plate 57 begins to shift towards the lower cavity under the action of the gas pressure. Until the lifting plate 57 shifts to an appropriate position, the compressed gas in the upper cavity enters the rotating groove 24 through the air pipe, and then the compressed gas in the rotating groove 24 is ejected from the opening at the end of the spray pipe 25 far from the rotating shaft 21. S4. Utilize the reduction of the flow path when the compressed gas in the rotating groove 24 enters the spray pipe 25, resulting in an increase in the flow rate of the gas after passing through the spray pipe 25. Then the high-speed gas flow ejected from the spray pipe 25 will wash the surface of the lip brick during the grinding process. S5. After the lip brick is ground, the conveyor line 1 transports the ground lip brick to the area position of the coating unit 12. Then the drainage ball 17 contacts the surface of the lip brick to be coated. At the same time, the lip brick will press the drainage ball 17 and the telescopic rod to slide along the limiting rod. Then the drainage ball 17 no longer blocks the water outlet hole, and the permeating liquid in the storage box 15 can be discharged through the water outlet hole. S6. When the lip brick is displaced, the drainage ball 17 rotates under the action of the lip brick. The rotation of the drainage ball 17 will guide the permeating liquid in the storage box 15 to be discharged from the water outlet hole, so that the permeating liquid is coated on the surface of the lip brick to be detected. S7. The lip brick coated with the penetrant needs to be left standing for a period of time so that the penetrant can fully penetrate into the pores or cracks of the lip brick. Then, the excess penetrant on the surface of the curved surface to be detected is manually wiped off with a cleaning cloth. Next, the developer is manually sprayed onto the area to be detected of the lip brick. Finally, the lip brick to be detected is placed in an appropriate environment, and the area to be detected of the lip brick is irradiated with an ultraviolet lamp, so as to observe the cracks in the area to be detected of the lip brick. S8. When the double-output shaft motor 13 is running, the second output shaft thereon will drive the fan 33 to rotate. The rotation of the fan 33 will guide the surrounding gas to flow towards the direction of the collection cylinder 41. Then, the gas at the dust collection hood 31 area will be subjected to the traction force when the fan 33 rotates. Then, the flying dust particles will follow the fluid and enter the air collection box 32 from the dust collection hood 31, and finally enter the collection cylinder 41 from the air collection box 32. S9. When the fan 33 rotates, the centrifuge tube 42 and the drainage plate 43 outside the centrifuge tube 42 will also rotate synchronously. The dust particles in the fluid will contact the surface of the drainage plate 43 and the inner wall of the filter cylinder 44. At this time, the water body in the centrifuge chamber enters the drainage chamber under the action of centrifugal force, and the water body in the drainage chamber is discharged from the drainage hole under the action of centrifugal force. At this time, a water film adheres to the surface of the drainage plate 43. When the fluid passes through the collection cylinder 41, the dust particles in the fluid will be adsorbed by the water body. S10. The sewage is generated after the dust particles contact and mix with the water body. The sewage will gather at the bottom of the collection cylinder 41 and flow onto the guide plate 45, and then enter the filter cylinder 44 through the guide plate 45. The sewage entering the filter cylinder 44 will first pass through the filter plate 48, and the dust particles or particulate matters in the sewage will be intercepted by the filter plate 48. After the water body passes through the filter plate 48, it will mix with the water body at the bottom of the filter cylinder 44. S11. When the water body in the water tank 46 gradually drains from the drainage hole, the pressure inside the water tank 46 decreases, causing the water body inside the filter cylinder 44 to enter the water tank 46 through the return pipe 47 under the action of negative pressure.

10. A detection method for a lip brick crack detection device for photovoltaic glass as described in claim 9, characterized in that, Including the following steps: First, place the lip brick to be detected on the conveyor line (1), and then the conveyor line (1) transports the lip brick to the area of the grinding unit (2). The double-output shaft motor (13) drives the grinding disc (23) to grind the lip brick. Meanwhile, the first output shaft of the double-output shaft motor (13) drives the rotating rod (53) to rotate, causing the sliding shaft (55) to slide along the corrugated groove (531). During the sliding process of the sliding shaft (55), the linear frame (54) makes a reciprocating linear motion in the sliding cylinder (52), so that the piston (561) makes a linear reciprocating motion in the air cylinder (56). At this time, the gas outside the air cylinder (56) enters the air cylinder (56) through the first one-way valve, and then the gas in the air cylinder (56) enters the upper cavity of the pressure box (51) through the second one-way valve under the action of the piston (561). As the gas pressure inside the upper chamber of the pressure box (51) increases, the lifting plate (57) begins to shift towards the lower chamber under the action of the gas pressure. After the lifting plate (57) has shifted to an appropriate position, the compressed gas inside the upper chamber enters the rotating groove (24) through the trachea, and then the compressed gas inside the rotating groove (24) is ejected through the opening at the end of the jet pipe (25) far from the rotating shaft (21); By taking advantage of the fact that the flow path of the compressed gas entering the jet pipe (25) from the rotating groove (24) decreases, the flow velocity of the gas is accelerated after passing through the jet pipe (25), and then the high-speed air flow ejected from the jet pipe (25) will scour the surface of the lip brick during the grinding process; After the lip brick is ground, the conveying line (1) conveys the ground lip brick to the area position of the coating unit (12). Then, the drainage ball (17) contacts the surface of the lip brick to be coated. At the same time, the lip brick will press the drainage ball (17) and the telescopic rod to slide along the limiting rod. Then, the drainage ball (17) no longer blocks the water outlet hole, and the permeating liquid in the storage box (15) can be discharged through the water outlet hole; When the lip brick is shifted, the drainage ball (17) rotates under the action of the lip brick. The rotation of the drainage ball (17) will guide the permeating liquid in the storage box (15) to be discharged through the water outlet hole, so that the permeating liquid is coated on the surface of the curved surface of the lip brick to be detected; The lip brick coated with the permeating liquid needs to be left standing for a period of time so that the permeating liquid can fully penetrate into the pores or cracks of the lip brick. Then, manually wipe off the excess permeating liquid on the surface of the curved surface to be detected with a clean cloth, manually spray the developer towards the area to be detected of the lip brick, and finally place the lip brick to be detected in an appropriate environment, and irradiate the area to be detected of the lip brick with an ultraviolet lamp to observe the cracks in the area to be detected of the lip brick; When the dual-output shaft motor (13) is running, the second output shaft on it will drive the fan (33) to rotate. The rotation of the fan (33) will guide the surrounding gas to flow towards the collecting cylinder (41). Then, the gas in the area of the dust collecting hood (31) will be subjected to the traction force when the fan (33) rotates, and the flying dust particles will follow the fluid and enter the air collecting box (32) from the dust collecting hood (31), and finally enter the collecting cylinder (41) from the air collecting box (32); When the fan (33) rotates, the centrifugal tube (42) and the drainage plate (43) outside the centrifugal tube (42) will also rotate synchronously. The dust particles in the fluid will contact the surface of the drainage plate (43) and the inner wall of the filter cylinder (44). At this time, the water body in the centrifugal chamber enters the drainage chamber under the action of centrifugal force, and the water body in the drainage chamber is discharged from the drainage hole under the action of centrifugal force. At this time, there is a water film attached to the surface of the drainage plate (43). When the fluid passes through the collecting cylinder (41), the dust particles in the fluid will be adsorbed by the water body; After dust particles come into contact and mix with water, sewage is generated. The sewage will gather at the bottom of the collection cylinder (41) and flow onto the diversion plate (45), and then enter the filter cylinder (44) through the diversion plate (45). The sewage entering the filter cylinder (44) will first pass through the filter plate (48). The dust particles or particulate matters in the sewage will be intercepted by the filter plate (48). After the water body passes through the filter plate (48), it will mix with the water body at the bottom of the filter cylinder (44). When the water body in the water tank (46) gradually drains out through the liquid discharge hole, the pressure inside the water tank (46) decreases, causing the water body inside the filter cylinder (44) to enter the water tank (46) through the return pipe (47) under the action of negative pressure.
