Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an industrial wastewater treatment and recycling system and a wastewater treatment impurity removal device. Background Technology

[0002] With industrial development, petrochemicals occupy an important position in industry. Petroleum additives are needed during oil extraction, including demulsifiers, corrosion inhibitors, flocculants, and emulsifiers. In the production of petroleum additives, the reaction vessels need to be cleaned and rinsed, generating reaction washing water. This wastewater contains various organic substances such as sulfonated asphalt and lignite, and is dark brown in color. Untreated wastewater is directly discharged, causing pollution to receiving water bodies. The wastewater has a complex composition and variable properties; it also has a high content of organic matter, especially hydrocarbons and their derivatives, making it difficult to determine the quality and quantity of the wastewater.

[0003] Chinese invention patent CN109704488A discloses an industrial wastewater treatment and recycling system, including a shell with symmetrical mounting plates on its front and rear walls; a top plate on the left half of the shell; a cleaning roller installed between the mounting plates, with a cleaning plate on the cleaning roller and slide rails on both sides of the cleaning plate, and filter screens evenly arranged in the slide rails inside the cleaning roller; a motor for driving an internal fan to rotate is located at the bottom right side of the shell, with the fan shaft passing through a disc and offset from the center of the disc, and a ring surrounding the disc; an agitator is located inside the shell to the left of the ring, connected to the agitator by a connecting rod, with an elastic water bladder on the left side of the agitator, a one-way valve for one-way water inlet above the elastic water bladder, and a one-way valve for one-way water outlet on the right side of the elastic water bladder; guide teeth are evenly arranged on the agitator; an ozone purification unit is located in front of the discharge port; and a water purification device and a water purification tank are arranged sequentially to the right of the ozone purification unit.

[0004] However, the equipment is difficult to clean some larger particles of impurities during use, and the impurities after cleaning cannot be processed in a timely manner. As the equipment is used, the filter screen gradually becomes clogged, resulting in poor filtration effect and limited service life in actual use.

[0005] Therefore, it is necessary to provide an industrial wastewater treatment and recycling system and a wastewater treatment impurity removal device to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an industrial wastewater treatment and recycling system and a wastewater treatment impurity removal device to solve the existing problems in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A wastewater treatment impurity removal device includes a scraper; a cleaning unit; and a pressurizing unit. The scraper is arranged in a circular array. The cleaning unit is fixedly installed on one side of the scraper, and the pressurizing unit is installed inside the scraper. The scraper rotates to drive the cleaning unit and the pressurizing unit to remove impurities. First, the cleaning unit removes impurities, then the pressurizing unit draws in liquid and forms a high-pressure water jet to further remove impurities.

[0009] Preferably, the cleaning unit includes a connecting rod and a cleaning block; the connecting rod is fixedly disposed on one side of the scraper, and the cleaning block is fixedly disposed on one end of the connecting rod.

[0010] Preferably, the pressurization unit includes a telescopic rod; a venting chamber; an exhaust port; a piston body; a piston block; and a moving rod. Piston blocks are slidably disposed on both sides of the piston body, and a moving rod is fixedly disposed on the outer end face of the piston block. A through hole is provided in the middle of the piston body, and the telescopic rod is wrapped around the outside of the through hole. The telescopic rod is hollow, and its front end is connected to the edge of the scraper. The venting chamber is embedded at the connection point between the scraper and the telescopic rod, and the exhaust port extends through both ends of the venting chamber to the scraper.

[0011] An industrial wastewater treatment and recycling system includes a treatment tank and an impurity removal device for wastewater treatment. A guide tube is provided at the bottom of one side of the treatment tank. A horizontal shaft is provided in the inner cavity of the guide tube. Multiple scrapers and filter plates are evenly arranged in a ring array outside the horizontal shaft. The scrapers and filter plates are staggered. The horizontal shaft drives the filter plates to rotate. The scrapers are driven to reciprocate along the horizontal shaft axis by the cooperation of the limiting block on the outer side of the scraper and the limiting groove on the inner wall of the guide tube.

[0012] A reciprocating screw is provided on one side of the scraper, and a slider is provided on the outside of the reciprocating screw. Brush bristles are provided on the side of the slider near 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.

[0013] Preferably, the scraper is hollow inside.

[0014] Preferably, the outer side of the horizontal shaft is provided with a first groove and a second groove, which are arranged in a ring array and staggered on the outer side of the horizontal shaft.

[0037] Example 1:

[0038] like Figure 1-14 As shown, an industrial wastewater treatment and recycling system includes a treatment tank 1. A drain pipe 14 is provided on one side of the treatment tank 1, and a control valve is provided on the outside of the drain pipe 14. A guide cylinder 9 is provided at the bottom of the side of the treatment tank 1 away from the drain pipe 14. A horizontal axis 6 is provided inside the guide cylinder 9. Four filter plates 25 are evenly distributed in a ring array on the outside of the horizontal axis 6, and a scraper 24 is provided between two adjacent filter plates 25.

[0039] Furthermore, a first slot 32 and a second slot 33 are provided on the outer side of the horizontal axis 6. The first slot 32 and the second slot 33 are arranged in a circular array and alternately distributed on the outer surface of the horizontal axis 6. The filter plate 25 is slidably connected to the horizontal axis 6 through the second slot 33, so that the filter plate 25 can move relative to the horizontal axis 6 along its diameter direction along the second slot 33. A fixing block 18 is slidably connected inside the first slot 32, and the scraper 24 is fixedly connected to the fixing block 18. A driving block 20 is also slidably arranged in the inner cavity of the horizontal axis 6. 20 is fixed to the fixed block 18. A limiting block 19 is fixedly provided on the outer side of one of the scrapers 24. A limiting groove 28 that cooperates with the limiting block 19 is provided on the inner wall of the guide tube 9. The limiting groove 28 is spiral. When the limiting block 19 moves along the spiral limiting groove 28, it can drive the scraper 24 to move on the horizontal axis 6. Each scraper 24 is connected to the fixed block 18 and the driving block 20. Therefore, this structure can drive multiple scrapers 24 on the outer side of the horizontal axis 6 to move synchronously on the outer side of the horizontal axis 6.

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

[0041] Furthermore, to facilitate the circulation of sewage, the guide tube 9 is provided with a through inlet hole on the outer side inside the treatment tank 1, allowing sewage inside the treatment tank 1 to flow into the guide tube 9 through the inlet hole. A sealing cover is fixedly connected to the top of the guide tube 9 on the side away from the treatment tank 1, and an outlet hole for sewage to flow out is provided on the outer side inside the sealing cover. The outlet hole and the inlet hole are symmetrical to each other along the vertical plane. A water pump 15 is provided on the top of the sealing cover. 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. This structure can be used to draw water from inside the sealing cover into the treatment tank 1.

[0042] In operation, the motor output drives the drive shaft 2 to rotate, which in turn drives the horizontal shaft 6 to rotate via the first belt 5. The fixing block 18 on the scraper 24 engages with the horizontal shaft 6 through the first slot 32, and the filter plate 25 engages with the horizontal shaft 6 through the second slot 33. Therefore, the rotation of the horizontal shaft 6 drives the scraper 24 and the filter plate 25 to rotate. Wastewater from the treatment tank 1 enters the guide cylinder 9 through the inlet hole and passes through the rotating filter plate 25. The filter plate 25 filters particulate matter from the wastewater, and the filtered particles fall to the bottom between adjacent filter plates 25. As the filter plates 25 rotate, when they reach a vertically downward position, the particles fall into the guide cylinder 9. At the bottom, the wastewater with filtered residue removed can be pumped by the water pump 15 through the outlet on the guide tube 9 and then flow back into the treatment tank 1. When the scraper 24 rotates, it can drive the limiting block 19 on its outer side to rotate. The limiting block 19 cooperates with the spiral limiting groove 28 on the inner wall of the guide tube 9 to drive the slider 29 to move outside the horizontal axis 6. Then, through the fixing block 18, it drives the driving block 20 to slide in the inner cavity of the horizontal axis 6. This structure can limit the scraper 24 to slide outside the horizontal axis 6 and improve the stability of the scraper 24 sliding. 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, it can push the residue at the bottom of the guide tube 9 to both ends of the guide tube 9, which is beneficial for the later collection and treatment of the residue.

[0043] To facilitate the collection and sorting of residue, a storage tank 8 is fixedly connected to the bottom of the guide tube 9 by bolts. Openings 39 for residue to pass through are provided at both ends of the guide tube 9. Baffles 38 are hinged to both ends inside the storage tank 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 tank 8. A round hole is provided on the baffle 38 to allow water to flow through but not residue.

[0044] In use, when the scraper 24 pushes the residue to the baffle 38, the pressure of the second spring 37 can be overcome by the squeezing force on the baffle 38 to open the baffle 38. At this time, the residue pushed by the scraper 24 will fall into the storage tank 8 through the opening 39. After the water flows through the storage tank 8, it flows back from the baffle 38 at the other end of the storage tank 8 to the guide tube 9. Therefore, this structure can be used to collect the residue, which is convenient 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 meshes with the outside of the wire mesh screw, and a slider 29 is fixedly connected to the outside of the ball nut pair. A brush is provided on the side of the slider 29 near the filter plate 25. A spur gear 36 is fixedly connected to the top of the outside of the reciprocating screw 30. A protrusion 23 is provided on the side of the filter plate 25 near the wall of the guide cylinder 9. A long groove is provided on the side of the protrusion 23 near the reciprocating screw 30 on the scraper 24. A transmission tooth 27 that meshes with the spur gear 36 is provided inside the groove.

[0046] In use, when the scraper 24 moves outside the horizontal shaft 6, it can drive the reciprocating screw 30 to move, which in turn drives the spur gear 36 to move. Through the meshing of the spur gear 36 and the transmission gear 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 its outer side to move up and down, which is beneficial to drive 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, while the scraper 24 moves, the brush bristles are driven to move up and down on one side of the filter plate 25, thereby treating the residue on the filter plate 25. This 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 cylinder 9, in order to prevent the filter plate 25 from scraping the residue again, a magnetic plate 26 is provided at the bottom of the inner cavity of the guide cylinder 9, and a magnetic sheet is pasted on the side of the protrusion 23 near the cylinder wall of the guide cylinder 9. A notch is provided on the other side of the scraper 24, and a groove is provided at the bottom of the notch. A support block 31 is slidably fitted in the groove. A guide rod is fixedly connected to the bottom of the groove. The guide rod passes through the support block 31 and is slidably connected to the support block 31. A first spring 35 is provided on the outside of the guide rod. The first spring 35 is located between the scraper 24 and the support block 31. The end of the support block 31 near the guide cylinder 9 abuts against the protrusion 23.

[0048] In use, when the filter plate 25 rotates and approaches the bottom of the guide cylinder 9, the magnetic plate 26 repulses the magnetic sheet, generating an upward driving force on the filter plate 25. This causes the filter plate 25 to move upward along the second groove 33. At this time, the protrusion 23 on the filter plate 25 disengages from the inner wall of the guide cylinder 9, thus preventing the filter plate 25 from contacting the residue when passing the bottom of the guide cylinder 9. This structure ensures that the residue falling from the filter plate 25 remains at the bottom of the guide cylinder 9 and is not scraped up by the filter plate 25 again. The scraper 24 can then push the residue to both ends of the guide cylinder 9. The strip groove 34 on the drive block 20 allows the filter plate 25 to move upward normally without interfering with the drive block 20. At the same time, the support block 31 provides auxiliary support for the filter plate 25 and ensures that the protrusion 23 on the filter plate 25 is always in contact with the support block 31, preventing the residue from sliding out through the gap between the support plate and the protrusion 23.

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

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

[0051] In use, the drive shaft 2 drives the active bevel gear 3 to rotate. The meshing of the active bevel gear 3 and the driven bevel gear 4 drives the vertical shaft 10 to rotate. The second belt 11 causes the vertical shaft 10 to drive the connecting pipe 12 to rotate, which in turn drives the turntable 16 to rotate. When the drive block 20 moves backward, it compresses the second airbag 21, forcing the gas in the second airbag 21 through the connector 22 to the return pipe 13. The gas is then transported through the return pipe 13 to the connecting pipe 12 and the interior of the turntable 16, and finally discharged through the exhaust hole on the turntable 16. The gas can be discharged into the sewage, and the rotation of the turntable 16 can pick up the residue and other particles deposited at the bottom of the treatment tank 1, making them float in the sewage. Then, they flow into the guide tube 9 along with the sewage, and the residue is further cleaned away by the cooperation of the filter plate 25 and the scraper 24. When the drive block 20 moves backward, it can cause the first air bag 17 to expand, thereby drawing in outside air through the air inlet pipe 7, causing the first air bag 17 to expand. Then, the drive block 20 moves forward to squeeze the first air bag 17, causing the gas inside to be output into the turntable 16.

[0052] This device uses the vent holes on the turntable 16 to roll up the residue deposited inside the treatment tank 1, allowing it to flow with the sewage into the guide cylinder 9. The scraper 24 and filter plate 25 work together to push the residue to both ends of the guide cylinder 9, and then transport it into the storage tank 8 for easy cleaning later. The slider 29 and brush on one side of the scraper 24 can clean the filter plate 25 in real time to prevent it from clogging.

[0053] Example 2:

[0054] A wastewater treatment impurity removal device includes a scraper 24; a cleaning unit; and a pressurizing unit. The scraper 24 is arranged in a circular array. The cleaning unit is fixedly installed on one side of the scraper 24, and the pressurizing unit is installed inside the scraper 24. The rotation of the scraper 24 drives the cleaning unit and the pressurizing unit to operate, thereby removing impurities. First, the cleaning unit removes impurities, then the pressurizing unit draws in liquid and forms a high-pressure water jet to further remove 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 pressurization unit includes a telescopic rod 403; a venting chamber 404; an exhaust port 405; a piston body 406; a piston block 407; and a moving rod 408. Piston blocks 407 are slidably disposed on both sides inside the piston body 407. A moving rod 408 is fixedly disposed on the outer end face of the piston block 407. A through hole is provided in the middle of the piston body 407. The telescopic rod 403 is wrapped around the outside of the through hole. The telescopic rod 403 is hollow. The front end of the telescopic rod 403 is connected to the edge of the scraper 24. The venting chamber 404 is embedded at the connection position between the scraper 24 and the telescopic rod 403. The exhaust port 405 extends through the end of the venting chamber 404 to both ends of the scraper 24.

[0057] An industrial wastewater treatment and recycling system includes a treatment tank and an impurity removal device 40 for wastewater treatment. A guide tube is provided at the bottom of one side of the treatment tank. A horizontal shaft is provided in the inner cavity of the guide tube. Multiple scrapers and filter plates are evenly arranged in a ring array outside the horizontal shaft. The scrapers and filter plates are staggered. The horizontal shaft drives the filter plates to rotate. The scrapers are driven to reciprocate along the horizontal shaft axis outside the horizontal shaft by the cooperation of the limiting block on the outer side of the scraper and the limiting groove on the inner wall of the guide tube.

[0058] A reciprocating screw is provided on one side of the scraper, and a slider is provided on the outside of the reciprocating screw. Brush bristles are provided on the side of the slider near 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, the outer side of the horizontal shaft is provided with a first groove and a second groove, which are arranged in a ring array and staggered on the outer side of the horizontal shaft. The filter plate is slidably connected to the horizontal shaft through the second groove. A fixing block is slidably connected inside the first groove. The scraper is fixedly connected to the fixing block. A driving block is slidably arranged in the inner cavity of the horizontal shaft. The driving block is fixed to the fixing block.

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

[0062] Specifically, the ends of the moving rods 408 at both ends of the piston body 406 are fixedly connected to the bottom of a slider 29. The wastewater treatment impurity removal device is organically linked with the industrial wastewater treatment and recycling system. The scraper moves in the limiting groove inside the guide tube through the limiting block. The cleaning block cleans the limiting groove on the scraper. Since the up and down movement of the slider can drive the moving rod to move left and right inside the piston body, the water flow is sucked into the telescopic rod through the exhaust hole and then a high-pressure water flow is sprayed out to further clean the impurities in the limiting groove, so that the device can operate smoothly.

[0063] Working principle: The motor output drives the transmission shaft 2 to rotate, which in turn drives the horizontal shaft 6 to rotate via the first belt 5. The fixed block 18 on the scraper 24 engages with the horizontal shaft 6 through the first slot 32, and the filter plate 25 engages with the horizontal shaft 6 through the second slot 33. Therefore, the rotation of the horizontal shaft 6 drives the scraper 24 and the filter plate 25 to rotate. The sewage inside the treatment tank 1 enters the guide cylinder 9 through the inlet hole and passes through the rotating filter plate 25. The filter plate 25 filters the particulate matter in the sewage, and the filtered particulate matter falls to the bottom between two adjacent filter plates 25. When the particles between the two filter plates 25 rotate to a vertically downward position, they fall to the bottom of the guide cylinder 9. The wastewater with the residue removed can be pumped by the water pump 15 through the outlet on the guide cylinder 9 and then flow back into the treatment tank 1. When the scraper 24 rotates, it can drive the limiting block 19 on its outer side to rotate. Through the cooperation of the limiting block 19 and the spiral limiting groove 28 on the inner wall of the guide cylinder 9, the slider 29 can be driven to move outside the horizontal axis 6. Then, through the fixing block 18, the driving block 20 can be driven to slide in the inner cavity of the horizontal axis 6. This structure can limit the scraper 24 to slide outside the horizontal axis 6, and on the other hand, it can... To improve the stability of the scraper 24's sliding motion, since the outer edge of the scraper 24 contacts the inner wall of the guide cylinder 9, when the scraper 24 moves, it can push the residue settled at the bottom of the guide cylinder 9 to both ends of the guide cylinder 9, which is beneficial for the later collection and treatment of the residue. When the scraper 24 moves outside the horizontal shaft 6, it can drive the reciprocating screw 30 to move, which in turn drives the spur gear 36 to move. Through the meshing of the spur gear 36 and the transmission gear 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 its outer side to move up and down, which is beneficial for 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. The movement mechanism drives the brush bristles to move up and down on one side of the filter plate 25 while the scraper 24 moves, thereby treating the residue on the filter plate 25. This prevents the residue and other particles from clogging the filter plate 25, thus extending its service life. The wastewater treatment impurity removal device is organically linked with the industrial wastewater treatment and recycling system. The scraper moves in the limiting groove inside the guide tube through the limiting block, and the cleaning block cleans the limiting groove on the scraper. The up and down movement of the slider can drive the moving rod to move left and right inside the piston body. After the water flow is drawn into the telescopic rod through the exhaust hole, it forms a high-pressure water jet that is sprayed out to further clean the impurities in the limiting groove, allowing the device to operate smoothly.
