Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, and in particular to a device for recycling wastewater after electrophoresis rinsing. Background Technology

[0002] Post-electrophoresis rinsing is an indispensable step in the electrophoretic coating process. After the workpiece is removed from the electrophoresis tank, it is thoroughly cleaned with deionized water using multi-stage spraying and immersion to remove residual electrophoretic paint and impurities from the workpiece surface. This ensures the smoothness and uniformity of the coating appearance and improves the coating quality and adhesion. However, the rinsing process generates a large amount of wastewater carrying electrophoretic paint components and impurities. Direct discharge of this wastewater not only wastes paint but also causes environmental pollution. Therefore, wastewater recycling has become an important measure to ensure the sustainable development of the electrophoretic coating process.

[0003] A search revealed Chinese Patent Publication No. CN211411144U, which discloses a wastewater recycling device and its usage method. The device includes a recycling pipe, a movable part, and a fixed part. The top of the recycling inlet pipe has an end cap. The movable part is fixed to the recycling inlet pipe with a nut. A filter screen is installed at the bottom of the movable part. The fixed part is connected to the recycling outlet pipe by internal screws. The movable part and the fixed part are connected and fixed by a pair of snap-fit ​​structures. This utility model relates to the field of wastewater recycling technology and has the following beneficial effects: the structure is easy to disassemble, making pipe maintenance simpler and more convenient. However, in actual use, manual disassembly and cleaning of the filter screen is required. Manual disassembly and cleaning is not only labor-intensive and cumbersome, but also affects the continuous operation of the wastewater recycling system due to downtime for cleaning. Especially in large-scale electrophoretic coating scenarios, frequent manual intervention reduces overall process efficiency. Furthermore, the disassembly process can lead to filter screen wear or decreased installation accuracy, affecting the filtration effect and equipment lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wastewater recovery device for post-electrophoresis rinsing, which aims to improve the problem that frequent manual intervention in the prior art reduces the overall process efficiency, and that disassembly can lead to filter wear or reduced installation accuracy, affecting the filtration effect and equipment lifespan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater recycling device for rinsing after electrophoresis, including a support frame, a sedimentation tank fixedly connected to the inner wall of the support frame, a collection mechanism provided inside the sedimentation tank, a lid threadedly connected to the top of the sedimentation tank, an agitation mechanism provided on the top of the lid, a connecting pipe connected to the bottom of the sedimentation tank, a filter box connected to the right side of the connecting pipe, a box cover rotatably connected to the top of the filter box, and a filtration mechanism provided inside the filter box; The filtration mechanism includes an installation ring, the outer wall of which is fixedly connected to the inner wall of the filter box. A filter plate is slidably connected to the top of the installation ring. A water pump is fixedly connected to the top of the box cover. A water pipe is slidably connected to the inner wall of the box cover. A high-pressure water gun is fixedly connected to the top of the inner wall of the box cover. A partition plate is fixedly connected to the inner wall of the filter box. A stabilizing component is provided on the left side of the partition plate.

[0006] The above technical solution provides a stable support for the filter plate, ensuring its stability during the filtration process and preventing shaking from affecting the filtration effect. The partition plate divides the filter box into an inlet area and an outlet area, so that wastewater can only flow from the inlet area to the outlet area through the filter plate, forcing the wastewater to undergo filtration treatment and ensuring that the filtration process is standardized and orderly.

[0007] As a further description of the above technical solution: The collection mechanism includes a collection box, the outer wall of which is slidably connected to the inner wall of the sedimentation tank. Two guide blocks are fixedly connected to the outer wall of the collection box, and two guide rails are fixedly connected to the inner wall of the sedimentation tank. An isolation plate is fixedly connected to the top of the collection box, and a water-passing block is fixedly connected to the top of the isolation plate. Multiple filter holes are opened in the upper middle part of the outer wall of the water-passing block.

[0008] The above technical solution allows for the following: the collection box is used to hold the precipitates produced by the flocculation reaction, facilitating centralized cleaning; the guide block and guide rail work together to make the collection box easy to install and disassemble and stable in position during operation; the isolation plate separates the space of the sedimentation tank to prevent the precipitates from mixing back into the supernatant; and the filter holes on the water-passing block perform preliminary filtration of the wastewater, reducing the load on subsequent treatment and effectively improving the overall treatment efficiency.

[0009] As a further description of the above technical solution: The agitation mechanism includes a servo motor, the bottom of which is fixedly connected to the top of the bucket lid, and the output end of the servo motor is fixedly connected to a transmission rod. The interior of the sedimentation tank is equipped with a mixing component.

[0010] The above technical solution involves a servo motor providing power to the agitation mechanism, and a transmission rod transmitting the power to the mixing components.

[0011] As a further description of the above technical solution: The stabilizing component includes two pressure strips, the outer walls of which are rotatably connected to the inner wall of the partition plate. Two rotating grooves are formed on the left side of the outer wall of the partition plate.

[0012] Through the above technical solution: the pressure bar rotates and presses the filter plate through the rotating groove, forming a sealing structure between the partition plate and the filter plate, preventing unfiltered wastewater from flowing sideway and ensuring that the water quality of the filtration unit meets the standards.

[0013] As a further description of the above technical solution: The mixing assembly includes two connecting shafts, the outer walls of which are fixedly connected to the outer wall of the transmission rod. The bottom of each connecting shaft is fixedly connected to a screw ribbon. The middle of the outer wall of each screw ribbon is fixedly connected to the same stirring band. The bottom of each screw ribbon is fixedly connected to the same bottom scraper.

[0014] The above technical solution involves the connecting shaft transmitting the rotational motion of the transmission rod to the screw belt and the stirring belt. The screw belt generates axial water flow, while the stirring belt provides radial shear force. The two work together to form a composite flow field in the wastewater, enhancing the flocculation effect. The bottom scraper prevents sediment accumulation and ensures smooth water flow.

[0015] As a further description of the above technical solution: The top left side of the bucket lid is connected to a water inlet, and the top right side of the bucket lid is connected to a medicine inlet.

[0016] The above technical solution allows for the introduction of wastewater to be treated through the inlet and the addition of flocculant through the agent inlet, enabling the wastewater and agent to mix quickly in the sedimentation tank and improving the efficiency of the initial treatment.

[0017] As a further description of the above technical solution: The filter box has a water outlet on its right side, and the bottom end of the water pipe is located on the right side of the inner wall of the filter box.

[0018] Through the above technical solution: the outlet is used to discharge the treated and qualified clean water to realize water resource reuse, and the water pipe transports the filtered clean water to the high-pressure water gun to provide water source for backwashing of the filter plate and ensure the continuous and stable operation of the filtration mechanism.

[0019] As a further description of the above technical solution: The bottom of the bottom scraper is slidably connected to the top of the isolation plate, and the inner wall of the bottom scraper is slidably connected to the outer wall of the water-passing block.

[0020] Through the above technical solution: the bottom scraper slides closely against the isolation plate and water passage block during the mixing process, sweeping away residual sediment, preventing it from clogging the water passage, ensuring the normal operation of the collection mechanism, and maintaining the continuity of the wastewater treatment process.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the pre-separated wastewater from the collection mechanism is transported to the left inlet area of ​​the filter box via a connecting pipe. The partition plate separates the box, allowing wastewater to flow only through the filter plate to the right outlet area, thus achieving deep purification of the wastewater. This effectively removes fine particles and colloids, ensuring that the effluent meets reuse standards. When the filter plate needs cleaning, the water pump, water pipe, and high-pressure water gun work together to backwash the filter plate, avoiding manual disassembly and forming a highly efficient circulating filtration system.

[0022] 2. In this utility model, the stirring mechanism promotes the flocculation reaction. After the stirring stops, the bottom scraper sweeps the sediment into the collection box. The water flows through the filter holes of the water block into the connecting pipe and flows to the filtration mechanism, realizing efficient flocculation, sedimentation and preliminary separation of suspended solids and heavy metal ions in wastewater, reducing the processing load of the subsequent filtration mechanism and improving the overall wastewater treatment efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See attached document Figure 1 Appendix Figure 2 and attached Figure 5An embodiment of this utility model provides a wastewater recycling device for rinsing after electrophoresis, including a support 1. A sedimentation tank 2 is fixedly connected to the inner wall of the support 1. A collection mechanism 3 is provided inside the sedimentation tank 2 for initially collecting suspended solids and sediments in the wastewater. A lid 4 is threadedly connected to the top of the sedimentation tank 2. An agitation mechanism 5 is provided on the top of the lid 4 to fully mix the wastewater with the flocculant. A connecting pipe 6 is connected to the bottom of the sedimentation tank 2. A filter box 7 is connected to the right side of the connecting pipe 6. A lid 8 is rotatably connected to the top of the filter box 7. A filtration mechanism 9 is provided inside the filter box 7 for filtering out residual small particles in the water. The filtration mechanism 9 includes a mounting ring 901, whose outer wall is fixedly connected to the inner wall of the filter box 7, providing stable mounting support for the filter plate 902 and ensuring that the filter plate 902 is fixed in position during filtration. The top of the mounting ring 901 is slidably connected to the filter plate 902, achieving deep purification of wastewater by intercepting fine particles and colloidal substances. The top of the box cover 8 is fixedly connected to a water pump 903, and the inner wall of the box cover 8 is slidably connected to a water pipe 904. The top of the inner wall of the box cover 8 is fixedly connected to a high-pressure water gun 905. The water pump 903 draws filtered clean water from the right side of the filter box 7 through the water pipe 904, providing backwashing power for the high-pressure water gun 905 to rinse the surface of the filter plate 902. To remove intercepted impurities, prevent clogging, and extend the service life of the filter media, a partition plate 906 is fixedly connected to the inner wall of the filter box 7, dividing the interior of the filter box 7 into an inlet area and an outlet area. This ensures that wastewater can only flow from the inlet area to the outlet area through the filter plate 902, ensuring the orderly progress of the filtration process. A stabilizing component 907 is provided on the left side of the partition plate 906. The stabilizing component 907 includes two pressure strips 9071. The outer walls of the two pressure strips 9071 are rotatably connected to the inner wall of the partition plate 906. Two rotating grooves 9072 are opened on the left side of the outer wall of the partition plate 906. By rotating the pressure strips 9071, they are pressed tightly against the filter plate 902 to form a sealed structure, preventing unfiltered wastewater from directly entering the outlet area and ensuring the filtration effect. Specifically, the filtration mechanism 9 uses filter plate 902 for filtration and high-pressure water gun 905 for backwashing of filter plate 902 to remove fine particles and colloids from the wastewater. The mounting ring 901 supports the filter plate 902, which intercepts impurities. The partition plate 906 divides the filter box 7 into inlet and outlet water zones. The pressure strip 9071 of the stabilizing component 907 ensures the filter plate is sealed. When it is necessary to clean the surface of the filter plate 902, the water pump 903 starts, and the water pipe 904 draws out the filtered water from the right side of the filter box 7. The filter plate 902 is then rinsed by the high-pressure water gun 905 to achieve automatic rinsing, extend the cleaning cycle and the service life of the filter material. The treated clean water can be reused in production after meeting the standards. The backwash wastewater is returned to the left side of the filter box 7 for recycling.

[0027] See attached document Figure 2 Appendix Figure 3 and attached Figure 4The collection mechanism 3 includes a collection box 301. The outer wall of the collection box 301 is slidably connected to the inner wall of the sedimentation tank 2 to hold the suspended solids and sediments. Two guide blocks 302 are fixedly connected to the outer wall of the collection box 301, and two guide rails 303 are fixedly connected to the inner wall of the sedimentation tank 2. These guide rails slide with the guide blocks 302 of the collection box 301 to provide a track for the collection box 301 to be installed and slid, while preventing it from shifting under the impact of water flow. A partition plate 304 is fixedly connected to the top of the collection box 301 to divide the interior of the sedimentation tank 2 into upper and lower spaces, so that the sediments are concentrated in the collection box 301 and the greywater flows out from the bottom, preventing the sediments from mixing back into the greywater and affecting subsequent treatment. A water-passing block 305 is fixedly connected to the top of the partition plate 304. Multiple filter holes 306 are opened in the upper part of the outer wall of the water-passing block 305. Through the gradient distribution of different hole sizes, the wastewater is initially filtered, reducing the load of subsequent treatment and improving the overall treatment efficiency. Specifically, the collection mechanism 3 achieves the initial collection of suspended solids and sediments in wastewater through physical interception and gravity sedimentation. The collection box 301 slides with the guide rail 303 of the sedimentation tank 2 via the guide block 302, ensuring stable positioning and easy disassembly. The isolation plate 304 on the top of the collection box 301 separates the sedimentation tank 2. The water passage block 305 on the top of the isolation plate 301 is provided with gradient-distributed filter holes 306, which can block most of the suspended solids and reduce the load on subsequent treatment. The inclination angle of the isolation plate 304 cooperates with the bottom scraper 5034 of the stirring mechanism 5, so that the sediments slide into the bottom of the collection box 301, completing the initial separation of solids and liquids, while protecting the subsequent filtration mechanism 9.

[0028] See attached document Figure 1 Appendix Figure 3 and attached Figure 4The agitation mechanism 5 includes a servo motor 501. The bottom of the servo motor 501 is fixedly connected to the top of the tank cover 4, serving as a power source to provide stable rotational power for the agitation mechanism 5, driving the transmission rod 502 to rotate, ensuring the agitation power required for the flocculation reaction. The bottom of the servo motor 501 is fixedly connected to the top of the tank cover 4 to achieve a stable installation of the servo motor 501, ensuring its fixed position during operation and preventing vibration from affecting the agitation effect. The output end of the servo motor 501 is fixedly connected to the transmission rod 502, transmitting the rotational power of the servo motor 501 to the mixing component 503, enabling the mixing component 503 to agitate and mix the wastewater. The mixing component 503 is installed inside the flocculation tank 2, and the wastewater and flocculant are fully mixed through mechanical agitation. This process promotes the formation of sediment from suspended solids and some organic matter, improving flocculation efficiency. The mixing component 503 includes two connecting shafts 5031, the outer walls of which are fixedly connected to the outer wall of a transmission rod 502. These shafts transmit the rotational motion of the transmission rod 502 to the screw ribbon 5032 and the stirring belt 5033, driving them to rotate and achieve a stirring function. The bottom of each connecting shaft 5031 is fixedly connected to a screw ribbon 5032, which generates axial thrust during rotation, causing the wastewater in the sedimentation tank 2 to form a circulating flow field, accelerating the diffusion rate of the flocculant in the wastewater. The middle of the outer wall of each screw ribbon 5032 is fixedly connected to the same stirring belt 5033, which generates radial shear force through a mesh structure, breaking down particulate matter in the wastewater and further promoting the formation of sediment from colloidal particles. The particles are destabilized and collide with each other to agglomerate, improving the speed and quality of floc formation. The bottom of both spiral ribbons 5032 is fixedly connected to the same bottom scraper 5034, which slides closely against the surface of the isolation plate 304 and the outer wall of the water-passing block 305 during stirring, preventing sediment from accumulating on the isolation plate 304 and the water-passing block 305, ensuring its water-passing efficiency, and guiding the sediment to gather at the bottom of the collection box 301. The bottom of the bottom scraper 5034 is slidably connected to the top of the isolation plate 304, ensuring that the bottom scraper 5034 can effectively clean the sediment on the surface of the isolation plate 304, maintaining the cleanliness and normal function of the isolation plate 304. The inner wall of the bottom scraper 5034 is slidably connected to the outer wall of the water-passing block 305, allowing the bottom scraper 5034 to clean the outer wall of the water-passing block 305, preventing sediment buildup. The filter holes 306 are blocked by sediment, ensuring smooth passage of wastewater. The top left side of the lid 4 is connected to the inlet 10, which is used to introduce the wastewater to be treated after electrophoresis rinsing into the sedimentation tank 2, providing the treatment object for the entire process. The top right side of the lid 4 is connected to the agent inlet 11, which facilitates the addition of flocculants and coagulants into the sedimentation tank 2, providing the necessary reagents for the flocculation reaction. The right side of the filter box 7 is connected to the outlet 12, which is used to discharge the qualified clean water after being treated by the filtration mechanism 9 for reuse in production, realizing the recycling of water resources. The bottom end of the water pipe 904 is located on the right side of the inner wall of the filter box 7, which transports the clean water filtered on the right side of the filter box 7 to the high-pressure water gun 905, providing a water source for the automatic rinsing of the filter plate 902 and ensuring the normal operation of the backwashing function. Specifically, after the wastewater to be treated enters the sedimentation tank 2 through the inlet 10, the flocculant is added through the inlet 11. The stirring mechanism 5 drives the transmission rod 502 to rotate through the servo motor 501, which in turn drives the mixing component 503 to achieve efficient flocculation reaction power transmission. The servo motor 501 is fixedly installed on the top of the tank cover 4, and its output end is connected to the transmission rod 502. After starting, the transmission rod 502 rotates at high speed and transmits power to the mixing component 503 through the connecting shaft 5031. The spiral ribbon 5032 is spiral in shape and generates axial thrust when rotating, which promotes the formation of a circulating flow field of wastewater and accelerates the diffusion of flocculant. The stirring belt 5033 generates radial shear force through the mesh structure, which breaks up particles and promotes coagulation. The bottom scraper 5034 is close to the isolation plate 304 to prevent the accumulation of sediment and guide it to gather at the bottom of the collection tank 301. After stirring, the wastewater is allowed to stand, the sediment settles, and the reclaimed water enters the subsequent treatment through the water passage block 305.

[0029] Working principle: The pre-separated wastewater from the collection mechanism 3 flows into the left inlet area of ​​the filter box 7 through the connecting pipe 6. The partition plate 906 divides the box into left and right parts, ensuring that the wastewater can only flow to the right outlet area through the filter plate 902. The filter plate 902, supported by the mounting ring 901, intercepts fine particles in the wastewater. The pressure strip 9071 of the stabilizing component 907 rotates and presses the filter plate 902 through the rotating groove 9072 to form a sealed interface, preventing unfiltered wastewater from flowing sideways. The purified water enters the right outlet area and is transported to the reuse system through the outlet 12. When the surface of the filter plate 902 needs to be cleaned, the water pump 903 draws clean water from the right outlet area and transports it to the high-pressure water gun 905 through the water pipe 904 to spray and rinse the surface of the filter plate 902. The stripped impurities flow back to the left inlet area with the backwash wastewater, mix with the newly flowing pre-treated wastewater, and are filtered again, forming a closed loop of filtration, rinsing, and filtration. Furthermore, after the wastewater to be treated enters the sedimentation tank 2 through the inlet 10, the flocculant is added through the inlet 11. Then, the servo motor 501 of the stirring mechanism 5 drives the transmission rod 502 to rotate, which in turn drives the screw ribbon 5032 and the stirring belt 5033 to form a composite flow field through the connecting shaft 5031. Under the action of the axial circulation of the screw ribbon 5032 and the radial shear force of the stirring belt 5033, the flocculant forms flocs with the suspended solids and heavy metal ions in the wastewater. After the stirring stops, the bottom scraper 5034 slowly stops rotating with the screw ribbon 5032, and its bottom slides along the surface of the isolation plate 304, sweeping the precipitate remaining on the isolation plate 304 to the bottom of the collection tank 301. The flocs and heavy metal hydroxides precipitate in the collection tank 301. The water enters the bottom space of the sedimentation tank 2 through the filter holes on the water block 305 and is transported to the filtration mechanism 9 through the connecting pipe 6.
