Description

Technical Field

[0001] This invention relates to the field of electroplating wastewater treatment technology, specifically to a continuous treatment equipment for rinsing wastewater from electroplated metal strips. Background Technology

[0002] In the field of metal strip electroplating rinsing wastewater treatment, liquid extraction filtration is a crucial step in achieving solid-liquid separation and ensuring purification effectiveness. As the core component of liquid extraction filtration, the stability and ease of cleaning of the filter element directly affect the overall operating efficiency and continuity of the wastewater treatment equipment. Currently, the liquid extraction filtration structure used in traditional electroplating wastewater treatment equipment has significant technical deficiencies, making it difficult to meet the needs of large-scale continuous industrial treatment.

[0003] Traditional wastewater treatment equipment typically uses a single set of filter elements in its pumping and filtration system. During long-term negative pressure pumping operations, flocculents and fine metal impurities from the wastewater continuously adhere to the surface of these filter elements. As these impurities accumulate, the filter elements are prone to clogging, leading to a significant decrease in pumping efficiency. Because only a single set of filter elements is used, once clogging occurs, the machine must be stopped to disassemble, clean, or replace the filter elements. The equipment can only be restarted after cleaning is completed. This operating mode not only interrupts the wastewater treatment process and seriously affects the overall efficiency of wastewater treatment, but also increases the labor intensity of operators, making it impossible to guarantee the needs of continuous industrial production.

[0015] This invention provides a continuous treatment device for rinsing wastewater from electroplating metal strips. Compared with the prior art, it has the following advantages: 1. By connecting two sets of filter elements in parallel at the inlet end of the liquid extraction component, and relying on the second flip switching component to drive the main board frame to achieve 180° flipping, the operation and cleaning are carried out simultaneously; when one set of filter elements is treating wastewater under negative pressure, the other set can enter the cleaning position at any time, completely avoiding the processing interruption caused by the shutdown for cleaning of traditional equipment, and improving the overall processing efficiency and industrial applicability. 2. The hollow filter plate and negative pressure adsorption structure utilize the hollow filter plate in conjunction with the filter cloth on both sides to form a negative pressure environment. This not only achieves efficient solid-liquid separation of wastewater from flocculants and metal precipitates, but also prevents impurities from penetrating and causing secondary pollution through strong adsorption, significantly enhancing the separation effect. The elastic sealing docking structure uses the elastic snap-fit ​​tongue and elastic release tongue of the docking components to automatically compensate for assembly gaps during high-intensity negative pressure pumping, effectively preventing channel leakage and ensuring the stability and efficiency of negative pressure pumping. 3. By driving the active backplate to move back and forth along the length of the cathode module, the upper and lower cleaning components are simultaneously driven to complete a large-area, sweeping cleaning, eliminating cleaning dead corners and ensuring complete separation of elemental metals and precipitates. The dual-mode function of the upper cleaning component integrates an active guide rail and a scraper transmission mechanism. It can not only adjust the scraper position according to the cathode module to achieve efficient scraping, but also raise the recovery box to a high position for easy and quick removal of metal waste. The combined cleaning action of the lower cleaning component combines the physical scraping of the shovel head with the water flushing of the spreader bar. Through the dual action of physical peeling and deep rinsing, the dry and hardened precipitates and residual impurities on the surface of the hollow filter plate are removed.

[0019] To address the technical problems in the background section, the following continuous treatment equipment for rinsing wastewater from electroplating metal strips is provided: Combination Figures 1-14 As shown, the continuous treatment equipment for rinsing wastewater from electroplating metal strips provided by the present invention includes: a primary sedimentation tank 100; a flocculation tank 200 connected to the output end of the primary sedimentation tank 100; a secondary sedimentation tank 300 located at the output end of the flocculation tank 200 for receiving the flocculated electroplating wastewater, wherein the bottom surface of the secondary sedimentation tank 300 is conical and has an installation notch 301, a sealing element 310 is embedded inside the installation notch 301, and constraint components 320 for constraining the sealing element 310 are provided on both sides of the installation notch 301; and an electrodeposition assembly 400 including a first flip-switch component 410 installed at the top inside the secondary sedimentation tank 300, with anode modules installed at both ends of the first flip-switch component 410. 420 and cathode module 430; liquid extraction assembly 500, which includes a lifting bracket 501, inside which a main board frame 502 and a liquid extraction component 510 are installed, and a set of filter elements 520 are installed at the top and bottom of the main board frame 502, with the outer end of the filter element 520 engaging with the sealing component 310; a liquid extraction component 510 is installed on one side of the main board frame 502 and a second flip switching component 530 is installed on the other side, and two sets of filter elements 520 are connected in parallel at the inlet end of the liquid extraction component 510; water purification component 600, whose inlet end is connected to the liquid extraction component 510 via a hose; dirt removal assembly 700, which includes an active backplate 701, with an upper cleaning component 720 installed at the top and a lower cleaning component 710 installed at the bottom of the active backplate 701; The secondary sedimentation tank 300 includes the following modes: In operation mode, one set of filter elements 520 is connected to the sealing element 310 and penetrates the installation notch 301, while another set of filter elements 520 is waiting to be connected; the anode module 420 and the cathode module 430 are vertically placed in the secondary sedimentation tank 300; the anode module 420 and the cathode module 430 are energized to adsorb metal impurities, and the liquid extraction component 510 extracts the liquid in the secondary sedimentation tank 300 and traps the impurities on the filter elements 520; In the switching mode, the first flip switching component 410 drives the anode module 420 and the cathode module 430 to rotate, and the upper cleaning component 720 cleans the cathode module 430. At the same time, the second flip switching component 530 drives the main board frame 502 to rotate, so that the filter element 520 after the operation rotates downward, and the lower cleaning component 710 cleans the filter element 520 after the operation.

[0020] Combination Figures 1-14 As shown, the primary sedimentation tank 100 is specifically equipped with three sets of independent sedimentation chambers 101. The three sets of sedimentation chambers 101 are arranged sequentially along the wastewater flow direction. An inclined sedimentation channel 102 is fixedly installed between two adjacent sedimentation chambers 101. The inclined sedimentation channel 102 is inclined downward, with one end connected to the bottom of the previous set of sedimentation chambers 101 and the other end connected to the top of the next set of sedimentation chambers 101, realizing the step-by-step guidance of wastewater. An inclined sedimentation channel 203 is set between the sedimentation chambers 101 and the flocculation tank 200. The inclined sedimentation channel 203 is also inclined downward, connecting the bottom of the last set of sedimentation chambers 101 and the top of the flocculation tank 200. Two sets of active stirring rods 201 are horizontally rotated inside the flocculation tank 200. The two sets of active stirring rods 201 are arranged in parallel, with stirring blades on the surface of the rods, and are driven synchronously by an external drive motor. Three sets of sedimentation chambers 101, together with inclined sedimentation channels 102, achieve graded sedimentation of wastewater, prolonging the residence time of wastewater in the primary sedimentation tank 100, and allowing large particles of impurities to settle fully. The inclined design of inclined sedimentation channels 102 and 103 can guide the smooth flow of wastewater and prevent settled impurities from being washed afloat by the water flow. Two sets of active stirring rods 201 rotate synchronously to fully stir the wastewater in the flocculation tank 200, so that the flocculant, wastewater and fine pollutants are evenly mixed, promoting the rapid formation of flocs.

[0021] Combination Figures 1-14As shown, the sealing component 310 is adapted to the installation notch 301 of the secondary sedimentation tank 300. A mating interface 311 for docking with the filter component 520 is centrally located at its bottom. symmetrical snap-fit ​​cavities 312 are formed on the left and right sides of the mating interface 311. Each snap-fit ​​cavity 312 has a built-in groove structure and is equipped with an elastically extendable tongue-and-loop mechanism 313. The elastic tongue-and-loop mechanism 313 is driven by a spring and extends partially outside the snap-fit ​​cavity 312 in its natural state. Two sets of constraint components 320 are provided corresponding to the snap-fit ​​cavities 312. Each set of constraint components 320 includes an electric push rod 322 and a positioning plug 321. The electric push rod 322 is fixedly installed on the inner wall of the secondary sedimentation tank 300 on both sides of the snap-fit ​​cavity 312, with the output end of the electric push rod 322 facing the snap-fit ​​cavity 312. The positioning plug 321 is fixedly installed on the output end of the electric push rod 322, and its shape is adapted to the snap-fit ​​cavity 312, allowing it to be inserted into the snap-fit ​​cavity 312 and engage with the elastic tongue-and-loop mechanism 313. The snap-fit ​​cavity 312 cooperates with the elastic release tongue 313 to provide a snap-fit ​​point for the positioning plug 321. The electric push rod 322 pushes the positioning plug 321 into the snap-fit ​​cavity 312, which engages and fixes with the elastic release tongue 313. This achieves a stable constraint on the sealing component 310 within the installation notch 301, preventing the sealing component 310 from shifting or loosening during equipment operation, ensuring the sealing of the installation notch 301, and avoiding wastewater leakage. The extension and retraction of the electric push rod 322 can drive the positioning plug 321 to separate from the snap-fit ​​cavity 312, and the elastic release tongue 313 to reset, facilitating the docking and separation of the filter element 520 and the sealing component 310. This adapts to the flip-over switching operation in the equipment switching mode, ensuring smooth switching.

[0022] Combination Figures 1-14As shown, the drive shaft 411 of the first flipping switching component 410 is vertically rotatably mounted inside the top of the secondary sedimentation tank 300. The drive shaft 411 is driven to rotate by an external drive motor. The top of the drive shaft 411 is fixedly mounted with a flipping arm 412, and the bottom is fixedly mounted with a flipping arm 413.

The rotation of the drive spindle 411 can drive the rotation of the first tilting arm 412 and the second tilting arm 413 synchronously, realizing the position switching of the anode module 420 and the cathode module 430. The cathode module 430 with adsorbed metal elements is rotated to the cleaning position, and the anode module 420 that is not in operation is rotated to the working position, ensuring that the electrodeposition operation is not interrupted. The drive spindles 415 and 416 can drive the cathode module 430 and the anode module 420 to rotate, so that the surface of the cathode module 430 is uniformly adsorbed with metal elements, and at the same time, it is convenient for the upper cleaning component 720 to clean the surface of the cathode module 430.

The top and bottom of the 22 are fixedly installed with docking components 540. The docking components 540 consist of a mating connector 541 and an elastic snap-fit ​​tongue 542. The mating connector 541 is adapted to the mating interface 311 of the docking seat 521 and the sealing component 310. The elastic snap-fit ​​tongue 542 that can be elastically extended is installed inside the mating connector 541. The two sides inside the docking seat 521 are installed with extended elastic release tongues 525. The elastic release tongues 525 cooperate with the slots of the mating connector 541 to fix the hollow filter plate 522. The butt joint 541 of the docking component 540 cooperates with the elastic snap-fit ​​tongue 542 to achieve quick docking and fixation of the hollow filter plate 522 with the sealing component 310 and the docking seat 521, ensuring a seal at the docking point and preventing wastewater leakage during liquid extraction; the elastic snap-fit ​​tongue 525 further reinforces the hollow filter plate 522 to prevent the filter component 520 from shifting during equipment operation; the filter holes 523 of the hollow filter plate 522 cooperate with the filter cloth 524 to achieve the filtration and separation of wastewater and sediment, and the filter cloth 524 can effectively trap fine sediment to ensure filtration effect; together with the liquid extraction component 510, a negative pressure is formed, causing the sediment to be adsorbed on the surface of the filter cloth 524, which is convenient for subsequent cleaning.

One end of the rigid tube 512 is connected to the flexible tube 513, which is a retractable hose, and the other end is connected to the water purification component 600. The other end of the rigid tube 512 extends to the main frame 502. Inside 02, two sets of flow hoses 514 are connected via a three-way connector. The two sets of flow hoses 514 are respectively connected to the hollow filter plates 522 at the top and bottom of the main board frame 502. The second flip-switching component 530 includes a second mounting bracket 531 and a rotating spindle 532. The second mounting bracket 531 is fixedly installed in the lifting bracket 501 on the other side of the main board frame 502. The rotating spindle 532 is rotatably installed between the second mounting bracket 531 and the main board frame 502. It is driven to rotate by an external drive motor, which drives the main board frame 502 to flip. Mounting bracket 511 provides stable support for rigid tube 512, which ensures the stability of the liquid extraction channel. Flexible tube 513 can adapt to the flipping and lifting of main frame 502. Two sets of diversion hoses 514 are respectively connected to two sets of filter elements 520 to achieve seamless connection between operation mode and switching mode, ensuring that when one set of filter elements is in operation, the other set is ready at any time. Rotating spindle 532 drives main frame 502 to rotate 180°, realizing the position switching of the two sets of filter elements 520, so that the filter element after operation enters the cleaning position, and the filter element waiting to be operated enters the working position, ensuring that the liquid extraction and filtration operation is continuous.

The scraper head 713 is made of wear-resistant material and fits against both sides of the hollow filter plate 522 for scraping off the sediment on the surface of the filter cloth 524. The push plate 711 pushes the scraper plate 712 close to the overturned hollow filter plate 522, and the scraper head 713 adheres to the surface of the filter cloth 524, which can effectively scrape off the adsorbed sediment and ensure that the filter cloth 524 is unobstructed; the spraying rod 714 is connected to a water supply pipe, and sprays clean water through the spraying hole to rinse the filter cloth 524, further cleaning the residual fine impurities, preventing the filter cloth 524 from clogging, and ensuring the filtration effect when the filter element 520 is used again; the inclined design and the hollow opening 715 of the scraper plate 712 make it easy for the scraped sediment and rinsing wastewater to fall into the collection component 800, avoiding the accumulation of impurities.

[0027] Combination Figures 1-14As shown, the upper cleaning component 720 is installed on the top of the active backplate 701, including an active guide rail 721 and a recovery component 730. The active guide rail 721 is vertically fixed to the front of the active backplate 701, and the guide seat of the active guide rail 721 can move up and down along the height direction of the guide rail to drive the recovery component 730 to move up and down. The recovery component 730 is fixedly installed on the guide seat of the active guide rail 721, including a recovery box 731, a mounting box 732, a scraper 733, a gear 734, and an active gear plate 735. The mounting box 732 is fixed on the guide seat. Two sets of recycling boxes 731 are symmetrically fixedly installed on both sides of the mounting box 732, with the openings of the recycling boxes 731 facing upwards. An inner mounting opening 736 is opened on the inner side of the recycling box 731, and a scraper 733 is rotatably installed in the inner mounting opening 736. The shaft end of the scraper 733 extends into the mounting box 732 and a gear 734 is fixedly installed. An active gear plate 735 is fixedly installed inside the mounting box 732. The active gear plate 735 meshes with the gear 734. An external drive component drives the active gear plate 735 to move, which in turn drives the gear 734 and the scraper 733 to rotate. The active backplate 701 is driven by a lead screw to move along the length of the cathode module 430, which drives the upper cleaning component 720 and the lower cleaning component 710 to move synchronously, thereby achieving a comprehensive cleaning of the surface of the cathode module 430 and the filter element 520. The active toothed plate 735 meshes with the drive gear 734, which drives the scraper 733 to rotate. The scraper 733 adheres to the surface of the cathode module 430, which can completely scrape off the adsorbed metal elements. The scraped metal elements fall into the recovery boxes 731 on both sides.

[0028] Combination Figures 1-14 As shown, the collection assembly 800 is located below the secondary sedimentation tank 300 and includes a base 801 and a collection tank 802. The active back plate 701 is fixedly installed on the top of the base 801. A guide rail is provided on the top of the base 801, and the collection tank 802 is slidably installed on the guide rail. The collection tank 802 is located below the lifting bracket 501. Its interior is divided into two independent collection chambers 803 by a partition. One collection chamber corresponds to the lower cleaning component 710 and is used to collect the sediment scraped by the shovel head 713 and the wastewater rinsed by the spreading rod 714. The other collection chamber corresponds to the recycling box 731 of the upper cleaning component 720. A push cylinder is fixedly connected to the base 801 on one side of the collection tank 802, and the output end of the push cylinder is connected to the collection tank 802. Two collection chambers 803 enable the classified collection of cleaned materials, preventing the precipitate from mixing with the metal element, facilitating subsequent treatment of the precipitate and recycling of the metal element; the drive cylinder drives the collection tank 802 to reciprocate, which can connect to the lower cleaning component 710 and the recycling box 731, ensuring that all cleaned materials fall into the collection tank 802 and avoiding leakage.

[0029] Working principle and usage process of this invention: S1. The rinsing wastewater from electroplated metal strips is first introduced into the primary sedimentation tank 100. The wastewater flows step by step in the three sedimentation chambers 101 in the primary sedimentation tank. The chambers are connected and guided by the inclined sedimentation channel 102. The large particulate suspended impurities in the wastewater are naturally settled in the sedimentation chamber 101 by gravity, which initially removes coarse particulate pollutants and reduces the load of subsequent treatment.

[0030] After initial sedimentation, the wastewater flows into the flocculation tank 200 through the inclined sedimentation channel 103. The two sets of active stirring rods 201 inside the flocculation tank 200 rotate synchronously to uniformly stir the wastewater, so that the fine pollutants in the wastewater are fully mixed and coagulated to form larger flocs, which facilitates subsequent secondary sedimentation and separation and improves the efficiency of subsequent treatment.

[0031] After flocculation, the wastewater flows into the secondary sedimentation tank 300. At this time, the equipment is in operation mode: the bottom of the secondary sedimentation tank 300 is conical, which facilitates the collection of sediment; the electric push rod 322 of the constraint component 320 pushes the positioning plug 321 and inserts it into the snap-fit ​​cavities 312 on both sides of the sealing component 310, which cooperates with the elastic release tongue 313 to achieve a stable constraint of the sealing component 310, ensuring that the installation gap 301 is in a sealed state and preventing wastewater leakage.

[0032] S2. Electrodeposition assembly 400 starts operation: The drive shaft 411 of the first flipping switching component 410 remains stationary, the flipping arms 412 and 413 are in a vertical position, and the anode module 420 and cathode module 430 are vertically placed in the wastewater of the secondary sedimentation tank 300; the telescopic arm 414 adjusts the height of the cathode module 430 to ensure that its distance from the anode module 420 is appropriate. After the power is turned on, the anode module 420 and the cathode module 430 form an electrolytic circuit. Under the action of the electric field, the metal ions in the wastewater migrate to the surface of the cathode module 430 and adsorb to form elemental metals, realizing the initial extraction of metal resources from the wastewater.

[0033] During the electrodeposition operation, the liquid extraction assembly 500 is activated: the lifting bracket 501 adjusts the height of the main board frame 502 so that a set of filter elements 520 at the bottom of the main board frame 502 aligns with the interface 311 of the sealing component 310; the filter elements 520 are inserted into the interface 311 through the connector 541 of the docking component 540, and the elastic snap-fit ​​tongue 542 cooperates with the snap-fit ​​cavity 312 to achieve fixation. At the same time, the elastic release tongue 525 in the docking seat 521 further fixes the hollow filter plate 522 to ensure a tight seal.

[0034] When the liquid extraction component 510 is activated, the rigid pipe 512 on the mounting bracket 511 drives the flexible pipe 513 and the diversion hose 514 to work simultaneously. The two diversion hoses 514 are connected to the filter elements 520 at the top and bottom of the main frame 502, respectively. A negative pressure is formed by an external air pump to extract the wastewater from the secondary sedimentation tank 300. The wastewater passes through the filter holes 523 on both sides of the hollow filter plate 522, and the filter cloth 524 traps the sediment in the wastewater. Under the action of negative pressure, the sediment is adsorbed on the surface of the hollow filter plate 522. The filtered wastewater is transported to the water purification component 600 through the diversion hose 514, the rigid pipe 512, and the flexible pipe 513.

[0035] Wastewater enters the water pipe 631 through the external connector 632 of the water guiding component 603 and flows into the water purification tank 601. After further adsorption and filtration by the water purification layer 602, the fine impurities and trace pollutants remaining in the wastewater are removed. The purified wastewater is discharged through another set of external connectors 632 connected to an external water pump, achieving the standard discharge of wastewater.

[0036] S3. When a large amount of deposits accumulate on the surface of the hollow filter plate 522 and sufficient metal adsorption occurs on the surface of the cathode module 430, the equipment switches to switching mode: S31. Electrodeposition Component Switching and Cleaning Preparation: The drive spindle 411 of the first flipping switching component 410 rotates, driving the flipping arm 412 and the flipping arm 413 to rotate synchronously, rotating the cathode module 430 with adsorbed metal elements to the corresponding position of the upper cleaning component 720 of the decontamination component 700, and at the same time rotating the unused anode module 420 into the secondary precipitation tank 300 to continue the electrodeposition operation, ensuring that the electrodeposition process is not interrupted.

[0037] S32. Filter element switching and cleaning preparation: The rotating spindle 532 of the second flip switching component 530 rotates, driving the main board frame 502 to rotate 180°, so that the filter element 520 with precipitates adsorbed after operation, originally the bottom filter element, rotates downward and aligns with the lower cleaning component 710 of the decontamination component 700; at the same time, the filter element 520 originally waiting to be docked at the top rotates to the bottom and docks with the interface 311 of the sealing component 310, and is fixed by the docking component 540, quickly entering the working state to ensure that the liquid extraction and filtration operation is carried out continuously.

[0038] During the switching process, the electric push rod 322 of the constraint component 320 extends and retracts, causing the positioning plug 321 to separate from the snap-fit ​​cavity 312, and the elastic release tongue 313 to reset, facilitating the docking and separation of the filter element 520 and the sealing element 310, ensuring smooth switching; the lifting bracket 501 synchronously adjusts the height of the main board frame 502 to cooperate with the flipping and switching of the filter element, avoiding interference with the secondary sedimentation tank 300.

[0039] S4. In switching mode, the cleaning component 700 and the collection component 800 operate synchronously to clean the filter elements and cathode module after the operation, and collect the cleaned materials separately. S41. Filter cleaning: The lower cleaning component 710 is activated, and the push plate 711 on the active back plate 701 pushes the scraper plate 712 close to the flipped hollow filter plate 522. The scraper head 713 on the end face of the scraper plate 712 fits against both sides of the hollow filter plate 522 to scrape off the sediment adsorbed on the surface. At the same time, the spraying rod 714 is connected to a water supply pipe and sprays clean water through the spraying hole to rinse the filter cloth 524 of the hollow filter plate 522 to ensure that the filter hole 523 is unobstructed. The rinsing wastewater and the scraped sediment fall through the hollow opening 715 of the scraper plate 712.

[0040] S42. Cathode Module Cleaning: The active backplate 701 is driven by a lead screw to move along the length of the cathode module 430, causing the upper cleaning component 720 to move synchronously. When the upper cleaning component 720 is activated, the active guide rail 721 drives the recovery component 730 to rise and fall to the appropriate height, ensuring that the scraper 733 is in contact with the surface of the cathode module 430. The active toothed plate 735 in the mounting box 732 meshes with the drive gear 734, causing the scraper 733 to rotate. The scraper 733 is in contact with the surface of the cathode module 430, scraping off the adsorbed elemental metal. The scraped elemental metal falls into the recovery boxes 731 on both sides, realizing the recycling of metal resources. The drive spindle 415 rotates synchronously, causing the cathode module 430 to rotate. In conjunction with the movement of the active backplate 701, the scraper 733 ensures that the surface of the cathode module 430 is thoroughly cleaned.

[0041] S43. Sorted Collection: The push cylinder of the collection component 800 drives the collection tank 802 to reciprocate on the base 801. The two collection chambers 803 in the collection tank 802 are respectively connected to the lower cleaning component 710 and the upper cleaning component 730: one collection chamber collects the sediment scraped by the shovel head 713 and the wastewater rinsed by the spreading rod 714, and the other collection chamber collects the metal elements that fall from the recycling box 731, realizing the sorted collection of the cleaned materials, which is convenient for subsequent processing and resource recycling.

[0042] S5. After cleaning, the equipment switches back to the operating mode: the first flip-switch component 410 drives the cleaned cathode module 430 to rotate into the secondary sedimentation tank 300 to continue the electrodeposition operation; the second flip-switch component 530 drives the cleaned filter element 520 to rotate to the top to await docking; the collection tank 802 moves to the designated position under the drive of the push cylinder to temporarily store the cleaned material, and removes it for processing after it is full. The entire process is repeated, realizing continuous treatment of electroplating rinsing wastewater, metal resource recovery, and wastewater discharge that meets standards.
