[0002] With the rapid development of the new energy industry, the demand for wastewater recycling equipment in emerging fields such as lithium battery material production has surged. Wastewater recycling equipment for metal material heat treatment is a special device for purifying and recycling wastewater generated during metal heat treatment.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 The diagram shows a wastewater recycling device for heat treatment of metal materials, including a frame 1. A mounting bracket 2 is fixedly installed on top of the frame 1. A large nozzle 3 is detachably installed below the mounting bracket 2. A small nozzle 4 is detachably installed on top of the frame 1. A water supply device 5 is fixedly installed on one side of the top of the frame 1. An inlet pipe 6 and two pipes 7 are detachably installed on the outside of the water supply device 5. The ends of the two sets of pipes 7 furthest from the water supply device 5 are connected to the large nozzle 3 and the small nozzle 4, respectively. A water tank 8 is fixedly installed below the frame 1. The end of the water inlet pipe 6 away from the water supply equipment 5 extends into the interior of the water tank 8. Both the front and rear ends of the water tank 8 are fixedly installed with tank bodies 9. The bottom of the water tank 8 and the tank bodies 9 are jointly provided with a through groove 29. The interior of the tank body 9 is provided with a filter mechanism, which includes a rotatable filter element 10. The filter element 10 is connected to the tank body 9 through a support structure. The filter element 10 is cylindrical in shape. The outer surface of the filter element 10 is provided with a groove 11. A first collection trough 15 is detachably installed on the side of the tank body 9 away from the water tank 8. Guide plates 12 are evenly installed on the outer surface of the filter element 10.

[0022] Specifically, the metal material is placed on the equipment frame 1 for processing. With the cooperation of the fixing frame 2, the water supply equipment 5 draws water from the inside of the water tank 8 through the water inlet pipe 6 and delivers it to the inside of the large nozzle 3 and small nozzle 4 through the pipe 7. The large nozzle 3 and small nozzle 4 spray water onto the surface of the metal material. The wastewater flows from the surface of the equipment frame 1 into the inside of the tank 9. The wastewater passes through the filter element 10, which can filter the wastewater. The filtered impurities enter the inside of the first collection tank 15. The filter element 10 can rotate. When rotating, the suspended matter on the surface of the wastewater can enter the inside of the filter element 10 through the tank opening 11. With the cooperation of the guide plate 12, the suspended matter is not blocked below the filter element 10, which facilitates the collection of suspended matter and prevents suspended matter from entering the inner wall of the pipe 7 with the wastewater, thus avoiding blockage of the pipe 7. The guide plate 12 can guide the impurities, so that the impurities and suspended matter can fall into the inside of the first collection tank 15.

[0023] The filter element 10 has a fixing block 18 inside. The fixing block 18 is connected to the tank 9 through a rotating structure. A brush 20 is provided on one side of the fixing block 18. The brush 20 is connected to the fixing block 18 through a telescopic component.

[0024] A cleaning component 21 is fixedly installed inside the tank 9 on one side near the first collection tank 15. The cleaning component 21 and the brush 20 are in contact and cooperate.

[0025] Specifically, the rotating structure drives the fixed block 18 to rotate, and the fixed block 18 drives the brush 20 to rotate. The rotation direction of the brush 20 is opposite to that of the filter element 10. The brush 20 can push the impurities and suspended matter inside the filter element 10 into the first collection tank 15 through the slot 11. In this process, the brush 20 can clean the inside of the filter element 10 to prevent the filter element 10 from becoming blocked. With the cooperation of the telescopic component, when the slot 11 rotates to the position of the first collection tank 15, the telescopic component drives the brush 20 to move to the position of the first collection tank 15, so that the brush 20 can contact the cleaning component 21 when it moves. The cleaning component 21 can clean the impurities and suspended matter wrapped inside the brush 20, thereby maintaining the use effect of the brush 20.

[0026] The rotating structure includes a rotating shaft 17, which rotates through the filter element 10. The rotating shaft 17 is rotatably connected to the tank 9. The rotating shaft 17 is fixedly connected to the fixing block 18. A motor 16 is fixedly installed at one end of the rotating shaft 17. The motor 16 is fixedly connected to the tank 9.

[0027] Specifically, the motor 16 is connected to an external power source, the motor 16 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the fixed block 18 to rotate synchronously.

[0028] The telescopic assembly includes a rod 22 that slides through a fixing block 18. A support plate 19 is fixedly installed on one end of the rod 22 near the brush 20. The support plate 19 and the brush 20 are fixedly connected. A first spring 25 is movably sleeved on the outer surface of the rod 22. The first spring 25 and the fixing block 18 are fixedly connected. A power structure is provided on the side of the rod 22 away from the support plate 19.

[0029] The power structure includes a first magnet 23 and a second magnet 24. The first magnet 23 is fixedly installed inside the filter element 10 on the side away from the slot 11, and the second magnet 24 is fixedly installed on the end of the rod 22 away from the brush 20. The first magnet 23 and the second magnet 24 repel each other.

[0030] In the initial state, the brush 20 is in contact with the inner wall of the filter element 10. When the slot 11 rotates to the position of moving the first collection slot 15, the second magnet 24 rotates to the position of the first magnet 23. Since the first magnet 23 and the second magnet 24 repel each other, the first magnet 23 can push the second magnet 24 to move closer to the first collection slot 15. Under the action of the fixing block 18, the second magnet 24 drives the fixing block 18 to move synchronously through the rod 22. At this time, the first spring 25 is deformed by force, and the fixing block 18 can drive the brush 20 to move synchronously, so that the brush 20 can penetrate the slot 11 and contact the cleaning element 21 when it moves.

[0031] The support structure includes a rotating component 13 and a guide groove 14. The rotating component 13 is fixedly installed at the end of the filter element 10, and the guide groove 14 is opened on the inner wall of the tank body 9. The rotating component 13 and the guide groove 14 are rotatably connected, and the rotating component 13 is connected to the rotating shaft 17 through a drive structure.

[0032] The drive structure includes a drive gear 26, which is fixedly sleeved on the outer surface of the rotating shaft 17. A driven gear 27 meshes with the outer surface of the drive gear 26. The driven gear 27 is rotatably connected to the groove 9. A gear ring 28 is fixedly installed inside the rotating part 13, and the gear ring 28 meshes with the driven gear 27.

[0033] When the rotating shaft 17 rotates, it can drive the driving gear 26 to rotate. Since the driving gear 26 meshes with the driven gear 27 and the driven gear 27 meshes with the gear ring 28, the rotating shaft 17 can drive the rotating component 13 to rotate. The rotating component 13 drives the filter element 10 to rotate inside the guide groove 14.

[0034] A slide plate 32 is installed at the bottom of the interior of the tank body 9. The slide plate 32 is located above the through groove 29. The slide plate 32 is connected to the tank body 9 through an elastic structure. A filter plate 31 is rotatably installed below the slide plate 32. The filter plate 31 is inclined. The end of the filter plate 31 away from the slide plate 32 is slidably connected to the bottom of the tank body 9. A push plate 35 is fixedly installed above the slide plate 32. A push block 36 is fixedly installed on the outer surface of the rotating part 13. The push block 36 and the push plate 35 are in contact and cooperate. A second collection tank 30 is fixedly installed on the side of the tank body 9 away from the water tank 8.

[0035] The elastic structure includes a support rod 33, which is fixedly installed inside the groove 9. The support rod 33 and the slide plate 32 are slidably connected. A second spring 34 is slidably sleeved on the outer surface of the support rod 33. The second spring 34 and the slide plate 32 are fixedly connected.

[0036] Specifically, when the rotating component 13 rotates, it drives the push block 36 to rotate. When the push block 36 rotates, it contacts the push plate 35 and drives the push plate 35 to move downward. The push plate 35 drives the slide plate 32 to move synchronously. At this time, the slide plate 32 slides on the outer surface of the support rod 33. The second spring 34 is deformed by force. When the slide plate 32 moves downward, it drives one end of the filter plate 31 to move downward. The end of the filter plate 31 away from the slide plate 32 slides at the bottom of the tank 9, thereby pushing the impurities at the bottom of the tank 9 into the interior of the second collection tank 30. When the push block 36 and the push plate 35 separate, under the elastic force of the second spring 34, the second spring 34 drives the slide plate 32 to move upward. When the slide plate 32 drives the filter plate 31 to move, the filter plate 31 plays a guiding role for the impurities. Moreover, the movement of the filter plate 31 can shake the impurities to the bottom of the tank 9, which is convenient for collecting the impurities at the bottom of the tank 9, so that the filtered wastewater can enter the interior of the water tank 8 through the through channel 29.

[0037] Working principle: The metal material is placed on the equipment frame 1 for processing. With the cooperation of the fixed frame 2, the water supply equipment 5 draws water from the inside of the water tank 8 through the water inlet pipe 6 and delivers it to the inside of the large nozzle 3 and the small nozzle 4 through the pipe 7. The large nozzle 3 and the small nozzle 4 spray water onto the surface of the metal material. The wastewater flows from the surface of the equipment frame 1 into the inside of the tank 9. The wastewater passes through the filter element 10, which can filter the wastewater.

[0038] Connect motor 16 to an external power source. Motor 16 drives shaft 17 to rotate, which in turn drives fixed block 18 to rotate synchronously. When shaft 17 rotates, it drives drive gear 26 to rotate. Since drive gear 26 meshes with driven gear 27 and driven gear 27 meshes with gear ring 28, shaft 17 can drive rotating component 13 to rotate. Rotating component 13 drives filter element 10 to rotate inside guide groove 14. When filter element 10 rotates, suspended solids on the surface of wastewater can enter the interior of filter element 10 through slot 11. With the cooperation of guide plate 12, suspended solids are not blocked below filter element 10, making it easier to collect them. This prevents suspended solids from entering the inner wall of pipe 7 with wastewater, thus avoiding blockage of pipe 7. Guide plate 12 can guide impurities, allowing impurities and suspended solids to fall into the interior of collection tank 15.

[0039] The fixed block 18 drives the brush 20 to rotate. The rotation direction of the brush 20 is opposite to that of the filter element 10. The brush 20 can push the impurities and suspended matter inside the filter element 10 into the first collection tank 15 through the slot 11. During this process, the brush 20 can clean the inside of the filter element 10 to prevent the filter element 10 from becoming clogged. With the cooperation of the telescopic component, when the slot 11 rotates to the position of the first collection tank 15, the telescopic component drives the brush 20 to move to the position of the first collection tank 15, so that the brush 20 can contact the cleaning component 21 when it moves. The cleaning component 21 can clean the impurities and suspended matter wrapped inside the brush 20, thereby maintaining the use effect of the brush 20.

[0040] When the rotating component 13 rotates, it drives the push block 36 to rotate. When the push block 36 rotates, it contacts the push plate 35 and drives the push plate 35 to move downward. The push plate 35 drives the slide plate 32 to move synchronously. At this time, the slide plate 32 slides on the outer surface of the support rod 33. The second spring 34 is deformed by force. When the slide plate 32 moves downward, it drives one end of the filter plate 31 to move downward. The end of the filter plate 31 away from the slide plate 32 slides at the bottom of the tank 9, thereby pushing the impurities at the bottom of the tank 9 into the interior of the second collection tank 30. When the push block 36 and the push plate 35 separate, under the elastic force of the second spring 34, the second spring 34 drives the slide plate 32 to move upward. When the slide plate 32 drives the filter plate 31 to move, the filter plate 31 guides the impurities and can shake the impurities to the bottom of the tank 9 through the movement of the filter plate 31, which facilitates the collection of impurities at the bottom of the tank 9, so that the filtered wastewater can enter the interior of the water tank 8 through the through channel 29.
