DETAILED DESCRIPTION

[0037] Embodiment 1:

[0038] like Figure 1-14 As shown, an industrial wastewater treatment and recovery system includes a treatment pool 1, a drain pipe 14 is arranged on one side of the treatment pool 1, a control valve is arranged on the outside of the drain pipe 14, a guide tube 9 is arranged at the bottom end of the treatment pool 1 away from the drain pipe 14, a horizontal axis 6 is arranged inside the guide tube 9, four filter plates 25 are evenly distributed in a circular array on the outside of the horizontal axis 6, and a scraper 24 is arranged between two adjacent filter plates 25.

[0039] Furthermore, a first notch 32 and a second notch 33 are provided on the outer side of the transverse axis 6, and the first notch 32 and the second notch 33 are staggeredly distributed on the outer side of the transverse axis 6 in a ring array. The filter plate 25 is slidably connected to the transverse axis 6 through the second notch 33, so that the filter plate 25 can move along the second notch 33 relative to the transverse axis 6 along its diameter direction, and the first notch 32 is slidably connected to the fixed block 18, and the scraper 24 is fixedly connected to the fixed block 18. A driving block 20 is also slidably provided at the inner cavity of the transverse axis 6, and the driving block 20 is fixed to the fixed block 18, and a limiting block 19 is fixedly arranged on the outer surface of one of the scrapers 24, and a limiting groove 28 matching the limiting block 19 is opened on the inner wall of the guide tube 9, and the limiting groove 28 is spiral. When the limiting block 19 moves along the spiral limiting groove 28, the scraper 24 can be driven to move on the horizontal axis 6, and each scraper 24 is connected by the fixed block 18 and the driving block 20. Therefore, this structure can drive multiple scrapers 24 on the outside of the horizontal axis 6 to move synchronously on the outside of the horizontal axis 6.

[0040] Furthermore, in order to drive the horizontal axis 6 to rotate, a motor is arranged on the outside of the treatment pool 1, and the output end of the motor is fixedly connected to the transmission shaft 2, and the outsides of the transmission shaft 2 and the horizontal axis 6 are fixedly connected to the first pulley, and the outside of the first pulley is sleeved with a first belt 5. In order to facilitate the installation of the first belt 5, the horizontal axis 6 passes through the guide tube 9 and extends to the outside of the guide tube 9. The horizontal axis 6 is rotatably connected to the guide tube 9 through a bearing.

[0041] Furthermore, in order to facilitate the circulation of sewage, a penetrating water inlet hole is provided on the outer side surface of the guide tube 9 located in the treatment tank 1, so that the sewage inside the treatment tank 1 can flow into the guide tube 9 through the water inlet hole, and a sealing cover is fixedly connected to the top of the guide tube 9 on the side away from the treatment tank 1, and a water outlet hole for sewage to flow out is provided on the outer side surface of the guide tube 9 located inside the sealing cover, and the water outlet hole and the water inlet hole are symmetrical to each other along the vertical plane, and a water pump 15 is provided on the top of the sealing cover, and the input end of the water pump 15 is connected to the sealing cover through a hose, and the output end of the water pump 15 is connected to the treatment tank 1 through a hose. Utilizing this structure, the water inside the sealing cover can be sucked into the treatment tank 1.

[0042] When in use, the transmission shaft 2 is driven to rotate through the output end of the motor, and the transmission shaft 2 can drive the horizontal axis 6 to rotate through the transmission of the first belt 5. The fixed block 18 on the scraper 24 cooperates with the horizontal axis 6 through the first notch 32, and the filter plate 25 cooperates with the horizontal axis 6 through the second notch 33. Therefore, the rotation of the horizontal axis 6 can drive the scraper 24 and the filter plate 25 to rotate. The sewage inside the treatment tank 1 enters the guide tube 9 through the water inlet hole on the guide tube 9 and passes through the rotating filter plate 25. The particles in the sewage can be filtered through the filter plate 25, and the filtered particles will fall to the bottom between the two adjacent filter plates 25. When the particles between the two filter plates 25 rotate to a vertical downward state with the filter plate 25, the particles will fall to the bottom of the guide tube 9. At the bottom, the sewage with the residue filtered out can be sucked by the water pump 15 through the outlet on the guide tube 9, and then flow back to the inside of the treatment tank 1. When the scraper 24 rotates, the limit block 19 on its outside can be driven to rotate. The limit block 19 cooperates with the spiral limit groove 28 on the inner wall of the guide tube 9 to drive the slider 29 to move on the outside of the horizontal axis 6, and then the driving block 20 is driven to slide in the inner cavity of the horizontal axis 6 through the fixed block 18. On the one hand, this structure can limit the scraper 24 to make it slide on the outside of the horizontal axis 6, and on the other hand, it can improve the sliding stability of the scraper 24. Since the outer edge of the scraper 24 is in contact with the inner wall of the guide tube 9, when the scraper 24 moves, the residue sunk at the bottom of the guide tube 9 can be pushed to the two ends of the guide tube 9, which is beneficial to the later collection and treatment of the residue.

[0043] In order to facilitate the collection and sorting of residues, a storage box 8 is fixedly connected to the bottom of the guide tube 9 by bolts, and openings 39 for the residues to pass through are respectively provided at both ends of the guide tube 9. Baffles 38 are hinged at both ends inside the storage box 8. A second spring 37 is provided on the side of the baffle 38 away from the guide tube 9. The second spring 37 is fixed to the inner wall of the storage box 8, and a circular hole is provided on the baffle 38 for water to pass through but residues cannot pass through.

[0044] During use, when the scraper 24 pushes the residue to the baffle 38, the squeezing force on the baffle 38 can overcome the pressure of the second spring 37 to open the baffle 38. At this time, the residue pushed by the scraper 24 will fall into the storage box 8 through the opening 39, and after the water flows through the storage box 8, it will flow back from the baffle 38 at the other end of the storage box 8 to the inside of the guide tube 9. Therefore, this structure can be used to collect the residue for later processing.

[0045] like Figure 5-13As shown, a storage groove is provided on one side of the scraper 24, and a reciprocating screw 30 is rotatably connected inside the storage groove, a ball nut pair is meshed on the outer side of the mesh screw, a slider 29 is fixedly connected to the outer side of the ball nut pair, a brush is provided on the side of the slider 29 close to the filter plate 25, a spur gear 36 is fixedly connected to the top end of the outer side of the reciprocating screw 30, and a protrusion 23 is provided on the side of the filter plate 25 close to the wall of the guide tube 9, a long strip-shaped groove is provided on the side of the protrusion 23 close to the reciprocating screw 30 on the scraper 24, and a transmission tooth 27 meshing with the spur gear 36 is provided inside the groove.

[0046] During use, when the scraper 24 moves outside the horizontal axis 6, it can drive the reciprocating screw 30 to move, and then drive the spur gear 36 to move. The meshing of the spur gear 36 and the transmission tooth 27 makes the spur gear 36 rotate during the movement, thereby driving the reciprocating screw 30 to rotate. The reciprocating screw 30 can drive the ball nut pair on its outer side to move up and down, which is conducive to driving the slider 29 and the brush on one side of it to move up and down on one side of the filter plate 25. Through this mechanism, the scraper 24 moves and the bristles are driven to move up and down on one side of the filter plate 25, so that the residue on the filter plate 25 is processed, which can prevent the residue and other particles from clogging the filter plate 25, thereby extending the service life of the filter plate 25.

[0047] like Figure 5-12 As shown, when the residue falls to the bottom of the guide tube 9, in order to prevent the filter plate 25 from scraping up the residue again, a magnetic plate 26 is arranged at the bottom position of the inner cavity of the guide tube 9, and a magnetic sheet is pasted on one side of the protrusion 23 close to the wall of the guide tube 9, and a notch is arranged on the other side of the scraper 24, and a slide groove is arranged at the bottom of the notch, and a support block 31 is slidably fitted at the slide groove, and a guide rod is fixedly connected to the bottom end of the inner part of the slide groove, and the guide rod passes through the support block 31 and is slidably connected to the support block 31, and a first spring 35 is arranged on the outside of the guide rod, and the first spring 35 is arranged between the scraper 24 and the support block 31, and the end of the support block 31 close to the guide tube 9 is against the protrusion 23.

[0048] When in use, when the filter plate 25 rotates and approaches the bottom of the guide cylinder 9, the repulsion of the magnetic plate 26 to the magnetic sheet can generate an upward driving force for the filter plate 25, thereby driving the filter plate 25 to move upward along the second notch 33. At this time, the protrusion 23 on the filter plate 25 is out of contact with the inner wall of the guide cylinder 9, so that the filter plate 25 can avoid contact with the residue when passing the bottom position of the guide cylinder 9. Through this structure, the residue dropped from the filter plate 25 will remain at the bottom of the guide cylinder 9 and will not be scraped up again by the filter plate 25, so that the scraper 24 can push the residue to the two ends of the guide cylinder 9, and by providing the strip groove 34 on the driving block 20, the filter plate 25 can move upward normally to avoid interference with the driving block 20. At the same time, by providing the support block 31, on the one hand, the filter plate 25 can be auxiliary supported, and on the other hand, the protrusion 23 on the filter plate 25 is always in contact with the support block 31, which can prevent the residue from slipping out through the gap between the support plate and the protrusion 23.

[0049] like Figure 5-14 As shown, a first airbag 17 is arranged at the front side of the driving block 20, and a second airbag 21 is arranged at the rear side of the driving block 20. The first airbag 17 and the second airbag 21 are both placed in the inner cavity of the horizontal axis 6, and a connector 22 is arranged at the end of the first airbag 17 and the second airbag 21 away from the driving block 20, and a reflux pipe 13 is connected through the connector 22. A turntable 16 is rotatably connected to the bottom end of the treatment pool 1, and an exhaust hole for air flow is arranged on the turntable 16, and a connector is fixedly connected to the bottom end of the turntable 16. A connecting pipe 12 is provided, the connecting pipe 12 passes through the treatment pool 1 and is rotatably connected to the treatment pool 1 through a sealed bearing. A tee is provided at the bottom end of the connecting pipe 12. The end of the return pipe 13 away from the connector 22 is connected to the tee. A first one-way valve is provided on the return pipe 13, so that the airflow in the return pipe 13 can only flow to the tee in one direction. An air inlet pipe 7 is provided at one end of the return pipe 13 close to the connector 22. A second one-way valve is provided at the air inlet pipe 7, so that the outside air flows to the inside of the return pipe 13 in one direction.

[0050] A vertical shaft 10 is arranged on the outside of the treatment pool 1, and a driven bevel gear 4 is fixedly connected to the top of the vertical shaft 10, and a driving bevel gear 3 meshing with the driven bevel gear 4 is fixedly connected to the outside of the transmission shaft 2. A second pulley is arranged on the bottom end of the outside of the vertical shaft 10 and the outside of the connecting pipe 12, and a second belt 11 is sleeved on the outside of the second pulley.

[0051] When in use, the driving bevel gear 3 can be driven to rotate through the transmission shaft 2, and the vertical shaft 10 can be driven to rotate through the meshing of the driving bevel gear 3 and the driven bevel gear 4. The vertical shaft 10 can drive the connecting pipe 12 to rotate through the second belt 11, and then the turntable 16 can be driven to rotate through the connecting pipe 12. When the driving block 20 moves backward, the second airbag 21 can be compressed, and the gas in the second airbag 21 is squeezed to the return pipe 13 through the connector 22, and then transported to the connecting pipe 12 and the inside of the turntable 16 through the return pipe 13, and then through the exhaust hole on the turntable 16. The gas can be discharged into the sewage, and the rotation of the turntable 16 can roll up the particles such as residues deposited at the bottom of the treatment tank 1, make them float in the sewage, and then flow into the guide tube 9 together with the sewage, and further clean up the residues through the cooperation of the filter plate 25 and the scraper 24. When the driving block 20 moves backward, it can cause the first airbag 17 to expand, thereby absorbing external air through the air intake pipe 7, causing the first airbag 17 to expand. After that, the driving block 20 moves forward to squeeze the first airbag 17 so that the gas inside it is output to the inside of the turntable 16.

[0052] Through this device, the exhaust holes on the turntable 16 can be used to roll up the residue deposited inside the treatment tank 1, so that it flows into the guide tube 9 with the sewage, and is pushed to the two ends of the guide tube 9 through the cooperation of the scraper 24 and the filter plate 25, and then transported to the storage box 8 for later cleaning. The slider 29 and the brush on one side of the scraper 24 can be used to clean the filter plate 25 in real time to avoid clogging.

[0053] Embodiment 2:

[0054] A device for removing impurities for wastewater treatment comprises a scraper 24, a cleaning unit and a booster unit. The scrapers 24 are arranged in a circular array, the cleaning unit is fixedly arranged on one side of the scraper 24, and the booster unit is arranged inside the scraper 24. The rotation of the scraper 24 drives the cleaning unit and the booster unit to operate, thereby removing impurities. The impurities are firstly removed by the cleaning unit, and then the liquid is absorbed by the booster unit, and then a high-pressure water flow is formed to be sprayed out to further remove the impurities.

[0055] Specifically, the cleaning unit includes a connecting rod 402 and a cleaning block 401 . The connecting rod 402 is fixedly disposed on one side of the scraper 24 , and the cleaning block 401 is fixedly disposed on one end of the connecting rod 402 .

[0056] Specifically, the booster unit includes a telescopic rod 403; a ventilation cavity 404; an exhaust hole 405; a piston body 406; a piston block 407; and a moving rod 408. Piston blocks 407 are slidably provided on both sides of the piston body 407, and a moving rod 408 is fixedly provided on the outer end face of the piston block 407. A through hole is provided in the middle position of the piston body 407, and the outer side of the through hole is wrapped with the telescopic rod 403. The telescopic rod 403 is hollow, and the upper end of the telescopic rod 403 is through-connected with the edge of the scraper 24. The ventilation cavity 404 is embedded in the connecting position of the scraper 24 and the telescopic rod 403, and the ends of the ventilation cavity 404 are penetrated by the exhaust holes 405 on the two end faces of the scraper 24.

[0057] An industrial wastewater treatment and recovery system comprises a treatment tank and an impurity removal device 40 for wastewater treatment, wherein a guide tube is arranged at the bottom end of one side of the treatment tank, a transverse axis is arranged at the inner cavity of the guide tube, a plurality of scrapers and filter plates are evenly arranged in a circular array outside the transverse axis, the scrapers and filter plates are staggered, the transverse axis drives the filter plates to rotate, and the limit blocks outside the scrapers cooperate with the limit grooves on the inner wall of the guide tube to drive the scrapers to reciprocate along the axis of the transverse axis outside the transverse axis;

[0058] A reciprocating screw is provided on one side of the scraper, a slider is provided on the outside of the reciprocating screw, bristles are provided on the side of the slider close to the filter plate, and a spur gear is provided on the outside of the reciprocating screw. When the scraper moves axially along the horizontal axis, the spur gear drives the reciprocating screw to rotate by meshing with the transmission teeth on the filter plate, and the slider moves along the outer side of the filter plate.

[0059] Specifically, the scraper 24 is hollow inside.

[0060] Specifically, a first slot and a second slot are provided on the outer side of the horizontal axis, and the first slot and the second slot are distributed in a ring array and staggered on the outer side of the horizontal axis. The filter plate is slidably connected to the horizontal axis through the second slot, and a fixed block is slidably connected inside the first slot, and the scraper is fixedly connected to the fixed block. A driving block is slidably provided in the inner cavity of the horizontal axis, and the driving block is fixed to the fixed block.

[0061] Specifically, the cleaning block 401 is slidably connected to the limiting groove 28 .

[0062] Specifically, the ends of the moving rod 408 at both ends of the piston body 406 are respectively fixedly connected to the bottom of the slider 29. The impurity removal device for wastewater treatment is organically linked with the industrial wastewater treatment and recovery system. The scraper moves in the limit groove through the limit block inside the guide cylinder, and the cleaning block cleans the limit groove on the scraper. Due to the up and down movement of the slider, the moving rod can be driven to move left and right inside the piston body. After the water flow is sucked into the telescopic rod through the exhaust hole, a high-pressure water flow is formed to spray out, which further cleans the impurities in the limit groove and allows the device to run smoothly.

[0063] Working principle: The transmission shaft 2 is driven to rotate through the output end of the motor, and the transmission shaft 2 can drive the horizontal axis 6 to rotate through the transmission of the first belt 5. The fixed block 18 on the scraper 24 cooperates with the horizontal axis 6 through the first notch 32, and the filter plate 25 cooperates with the horizontal axis 6 through the second notch 33. Therefore, the rotation of the horizontal axis 6 can drive the scraper 24 and the filter plate 25 to rotate. The sewage inside the treatment tank 1 passes through the water inlet hole on the guide tube 9 and passes through the rotating filter plate 25 during the process of entering the guide tube 9. The particles in the sewage can be filtered through the filter plate 25, and the filtered particles will fall to the bottom between the two adjacent filter plates 25, and the rotation of the filter plate 25 When the particles between the two filter plates 25 rotate to a vertically downward state with the filter plates 25, the particles will fall to the bottom of the guide tube 9, and the sewage with the filtered residues can be sucked by the water pump 15 through the water outlet on the guide tube 9, and then flow back to the inside of the treatment tank 1. When the scraper 24 rotates, it can drive the limit block 19 on its outer side to rotate. The limit block 19 cooperates with the spiral limit groove 28 on the inner wall of the guide tube 9 to drive the slider 29 to move outside the horizontal axis 6, and then drive the driving block 20 to slide in the inner cavity of the horizontal axis 6 through the fixed block 18. Through this structure, on the one hand, the scraper 24 can be limited to slide on the outside of the horizontal axis 6, and on the other hand, In order to improve the sliding stability of the scraper 24, since the outer edge of the scraper 24 contacts the inner wall of the guide tube 9, when the scraper 24 moves, the residue sunk at the bottom of the guide tube 9 can be pushed to the two ends of the guide tube 9, which is beneficial to the collection and treatment of the residue in the later stage. When the scraper 24 moves outside the horizontal axis 6, it can drive the reciprocating screw 30 to move, and then drive the spur gear 36 to move. Through the meshing of the spur gear 36 and the transmission tooth 27, the spur gear 36 rotates during the movement, thereby driving the reciprocating screw 30 to rotate. The reciprocating screw 30 can drive the ball nut pair on the outside thereof to move up and down, which is beneficial to drive the slider 29 and the brush on one side thereof to move up and down on one side of the filter plate 25. The scraper 24 moves, and the brush bristles are driven to move up and down on one side of the filter plate 25 through this mechanism while the scraper 24 moves, so that the residue on the filter plate 25 is processed, which can prevent the filter plate 25 from being blocked by particles such as residue, thereby extending the service life of the filter plate 25. The impurity removal device for wastewater treatment is organically linked with the industrial wastewater treatment and recovery system. The scraper moves in the limit groove through the limit block inside the guide cylinder, and the cleaning block cleans the limit groove on the scraper. Due to the up and down movement of the slider, the moving rod can be driven to move left and right inside the piston body. After the water flow is sucked into the telescopic rod through the exhaust hole, a high-pressure water flow is formed to be sprayed out, which further cleans the impurities in the limit groove and makes the device run smoothly.
