Description

Technical Field

[0001] This invention relates to the technical field, specifically to a device for purifying and treating heavy metal ions in electroplating wastewater. Background Technology

[0002] Electroplating is an important processing industry in my country, currently focusing on zinc plating, copper plating, cadmium plating, nickel plating, and chromium plating, and is concentrated in industrial fields such as machinery manufacturing, light industry, electronics, aerospace, and instrumentation.

[0003] In the process of treating electroplating wastewater, solid impurities in the water must first be intercepted by a filter screen before entering the sedimentation process. The filter screen operates continuously for a long time without interruption. Various solid impurities intercepted by the filter screen will continue to adhere to and accumulate on the surface of the filter screen. As the operating time increases, the accumulated impurities will gradually block the small filter pores of the filter screen, causing blockage of the filter screen flow channel, thereby reducing the effect of subsequent filtration treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a device for purifying and treating heavy metal ions in electroplating wastewater, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a heavy metal ion purification and treatment device for electroplating wastewater, comprising a sedimentation tank, a treatment cylinder fixedly connected to the top of the sedimentation tank, a motor fixedly connected to the surface of the treatment cylinder, an inlet pipe fixedly connected to the top of the treatment cylinder, and an outlet pipe fixedly connected to the bottom of the treatment cylinder, and further comprising; A filtration mechanism, comprising a filter rotating plate, wherein a scraper is fixedly connected to the end of the filter rotating plate, and a guide groove is provided on the surface of the scraper; A cleaning mechanism, comprising a slide bar, a cleaning rod fixedly connected to the surface of the slide bar, and a cleaning plate fixedly connected to the bottom of the cleaning rod; A vibration mechanism, comprising a lower push rod, an impact rod hinged to the end of the lower push rod, and a driven rod hinged to the surface of the impact rod.

[0006] Furthermore, the inner walls of both the inlet pipe and the outlet pipe are interconnected with the inner wall of the treatment cylinder, which is located above the sedimentation tank.

[0007] Furthermore, the filtration mechanism includes a toothed ring, a connecting plate fixedly connected to the inner wall of the toothed ring, a rotating shaft fixedly connected to the bottom of the connecting plate, a long rod fixedly connected to the surface of the rotating shaft, a stirring rod fixedly connected to the end of the long rod away from the rotating shaft, a filter disc rotatably connected to the bottom of the rotating shaft, and a toothed disc fixedly connected to the output end of the motor. This invention achieves thorough mixing and reaction of the reagent and wastewater through the stirring rod, and forms a multi-stage impurity filtration structure with the filter rotating plate and filter disc, significantly improving the impurity removal efficiency of electroplating wastewater. At the same time, the rotating scraper automatically cleans the scale accumulated on the cylinder wall, eliminating the need for manual disassembly and cleaning, effectively improving the self-cleaning efficiency of the equipment's inner wall and the continuity of overall wastewater treatment.

[0008] Furthermore, the inner wall of the toothed ring is slidably connected to the inner wall of the processing cylinder, the outer wall of the filter disc is fixedly connected to the inner wall of the processing cylinder, the toothed ring and the toothed disc mesh with each other, the end of the filter rotating plate away from the scraper is fixedly connected to the surface of the rotating shaft, the lower surface of the rotating shaft is provided with a moving groove, and the top of the filter rotating plate is provided with a groove.

[0009] Furthermore, the cleaning mechanism includes a rising slip ring, with a pull rod hinged to the outer wall of the rising slip ring, an anti-clogging plate fixedly connected to the bottom of the filter rotating plate, a collection ring slidably connected to the lower surface of the inner wall of the processing cylinder, and a handle fixedly connected to the outer wall of the collection ring. This invention can effectively prevent the filter rotating plate and filter disc from becoming clogged by impurities, thus reducing the filtration efficiency and eliminating the need for frequent manual disassembly and cleaning, thereby significantly reducing the labor intensity of manual operation and maintenance.

[0010] Furthermore, the end of the pull rod away from the rising slip ring is hinged to the surface of the slide rod, the surface of the cleaning rod is in contact with the surface of the filter rotating plate, the surface of the cleaning plate is in contact with the surface of the anti-clogging plate, the bottom of the anti-clogging plate is in contact with the surface of the filter disc, the inner wall of the collecting ring is in contact with the outer wall of the filter disc, the inner wall of the rising slip ring is slidably connected to the inner wall of the moving groove, and the end of the slide rod is slidably connected to the inner wall of the groove.

[0011] Furthermore, the vibration mechanism includes a slip ring, a return spring is fixedly connected to the bottom of the slip ring, a limit ring is fixedly connected to the surface of the stirring rod, a compression bending plate is fixedly connected to the outer wall of the slip ring, a support frame is fixedly connected to the upper surface of the inner wall of the processing cylinder, and a force-bearing inclined block is fixedly connected to the bottom of the support frame. The present invention uses the intermittent impact of the impact rod to vibrate the surface of the filter plate, and relies on the vibration force to peel off the dirt attached to the surface of the filter plate, which greatly improves the self-cleaning effect of the filter plate.

[0012] Furthermore, the end of the push rod away from the impact rod is hinged to the outer wall of the slip ring, the inner wall of the slip ring is slidably connected to the surface of the stirring rod, the top of the limiting ring is in contact with the bottom of the slip ring, the inner wall of the support frame is rotatably connected to the upper surface of the rotating shaft, the end of the driven rod away from the impact rod is hinged to the outer wall of the slip ring, and the inner wall of the return spring is in contact with the surface of the stirring rod.

[0013] The present invention has the following beneficial effects: This invention uses a motor to drive the entire stirring and filtering mechanism to rotate continuously. The stirring rod synchronously stirs the electroplating wastewater at high speed with the rotating shaft, which can make the precipitating agent and heavy metal ions in the wastewater fully and evenly mixed.

[0014] This invention uses a rotating filter plate to initially intercept solid impurities in water, and a bottom filter disc to perform secondary fine filtration of wastewater, forming a two-stage progressive filtration. The dual filtration can comprehensively intercept impurities of different particle sizes, significantly improving the filtration efficiency of impurities in electroplating wastewater.

[0015] This invention uses a scraper that rotates synchronously with the filter plate. The scraper continuously rotates and scrapes away the flocculation and dirt adhering to the inner wall of the treatment cylinder in real time. The scraped-off impurities automatically slide down along the scraper guide groove to the collection ring for centralized collection, eliminating the need for manual shutdown to scrub the cylinder wall.

[0016] This invention uses the centrifugal force generated by the rotation of the shaft to drive the slide rod to slide outward along the groove, which in turn causes the cleaning rod and cleaning plate to expand outward simultaneously. The cleaning rod directly contacts the surface of the filter plate to scrape off accumulated impurities and pushes the impurities into the guide groove and into the collection ring. The cleaning plate simultaneously cleans the accumulated dirt on the surface of the anti-clogging plate and pushes it into the collection ring. The anti-clogging plate rotates synchronously with the shaft, which can pre-collect impurities on the surface of the filter disc to prevent the filter disc from clogging, and there is no need to stop the machine to disassemble and clean the filter elements.

[0017] This invention uses a stirring rod to drive the vibration mechanism to rotate in a circular motion. The extrusion plate periodically engages with the fixed force-bearing inclined block, and the compression and reset spring stores and releases energy to complete the reciprocating motion. This drives the impact rod to intermittently strike the filter plate, causing it to vibrate continuously at a small amplitude. The vibration can shake off the small flocs that are stuck and tightly adhered to the filter holes of the filter plate, preventing the filter holes from becoming clogged and failing, continuously ensuring the permeability of the filter plate, and extending the continuous operation time.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-8 As shown, the present invention is a heavy metal ion purification and treatment device for electroplating wastewater, including a sedimentation tank 1, a treatment cylinder 2 fixedly connected to the top of the sedimentation tank 1, a motor 3 fixedly connected to the surface of the treatment cylinder 2, an inlet pipe 4 fixedly connected to the top of the treatment cylinder 2, and an outlet pipe 5 fixedly connected to the bottom of the treatment cylinder 2, and also includes; The filter mechanism 10 includes a filter rotating plate 16, and a scraper 17 is fixedly connected to the end of the filter rotating plate 16. A guide groove is provided on the surface of the scraper 17. The cleaning mechanism 30 includes a slide bar 33, a cleaning rod 34 fixedly connected to the surface of the slide bar 33, and a cleaning plate 35 fixedly connected to the bottom of the cleaning rod 34. The vibration mechanism 50 includes a lower push rod 54, an impact rod 55 is hinged to the end of the lower push rod 54, and a driven rod 56 is hinged to the surface of the impact rod 55.

[0024] The inner walls of the inlet pipe 4 and the outlet pipe 5 are connected to the inner wall of the treatment cylinder 2, which is located above the sedimentation tank 1.

[0025] The filtration mechanism 10 includes a toothed ring 11, a connecting plate 12 fixedly connected to the inner wall of the toothed ring 11, a rotating shaft 13 fixedly connected to the bottom of the connecting plate 12, a long rod 14 fixedly connected to the surface of the rotating shaft 13, a stirring rod 15 fixedly connected to the end of the long rod 14 away from the rotating shaft 13, a filter plate 18 rotatably connected to the bottom of the rotating shaft 13, and a toothed disc 19 fixedly connected to the output end of the motor 3. First, the electroplating wastewater to be treated is discharged into the interior of the treatment cylinder 2 through the inlet pipe 4. Then, the motor 3 is started to drive the toothed disc 19 to rotate. The toothed disc 19 meshes with the toothed ring 11 to rotate synchronously. The toothed ring 11 drives the connecting plate 12 and the rotating shaft 13 to rotate together. The rotating shaft 13 synchronously drives the long rod 14 and the filter rotating plate 16 to rotate. When the long rod 14 rotates, it drives the stirring rod 15 to continuously stir the water in the cylinder, so as to promote the full mixing and reaction of the reagent and the electroplating wastewater. During the stirring process, suspended impurities in the water can be intercepted and attached to the surface of the filter rotating plate 16. While the filter rotating plate 16 is rotating, it drives the scraper 17 to rotate synchronously.

[0026] The inner wall of the toothed ring 11 is slidably connected to the inner wall of the processing cylinder 2, the outer wall of the filter disc 18 is fixedly connected to the inner wall of the processing cylinder 2, the toothed ring 11 and the toothed disc 19 mesh with each other, the end of the filter rotating plate 16 away from the scraper 17 is fixedly connected to the surface of the rotating shaft 13, the lower surface of the rotating shaft 13 is provided with a moving groove, the top of the filter rotating plate 16 is provided with a groove, the scraper 17 continuously scrapes away the dirt adhering to the inner wall of the processing cylinder 2, the scraped impurities are collected along the guide groove of the cylinder wall into the collection ring 37 for centralized collection, and then pass through the cylinder. The pre-purified electroplating wastewater is discharged from the outlet pipe 5 and sent to the sedimentation tank 1. The wastewater undergoes secondary fine filtration when it flows through the filter disc 18 in the pipeline. The present invention achieves full mixing and reaction of the reagent and wastewater through the stirring rod 15. Combined with the filter rotating plate 16 and the filter disc 18, a multi-stage impurity filtration structure is formed, which greatly improves the impurity removal efficiency of electroplating wastewater. At the same time, the scraper 17 automatically cleans the scale on the cylinder wall without the need for manual disassembly and cleaning, effectively improving the self-cleaning efficiency of the inner wall of the equipment and the continuity of the overall wastewater treatment.

[0027] The cleaning mechanism 30 includes a rising slip ring 31, with a pull rod 32 hinged to the outer wall of the rising slip ring 31. An anti-clogging plate 36 is fixedly connected to the bottom of the filter rotating plate 16. A collection ring 37 is slidably connected to the lower surface of the inner wall of the processing cylinder 2. A handle 38 is fixedly connected to the outer wall of the collection ring 37. When the rotating shaft 13 and the filter rotating plate 16 rotate synchronously, the rising slip ring 31, pull rod 32, slide rod 33, cleaning rod 34, cleaning plate 35 and anti-clogging plate 36 rotate together. During the operation of the equipment, the anti-clogging plate 36 rotates with the rotating shaft 13 and can collect the intercepted impurities attached to the surface of the filter disc 18. During the rotation of the filter rotating plate 16, centrifugal force is generated, which drives the four sets of slide rods 33 to slide along the groove in a direction away from each other. When the slide rods 33 move, they simultaneously push the cleaning rods 34 to move in a direction away from each other, scraping off the impurities attached to the surface of the filter rotating plate 16 and pushing the impurities to the guide groove. When the cleaning rods 34 move, they drive the cleaning plate 35 to move synchronously.

[0028] The end of the pull rod 32 away from the rising slip ring 31 is hinged to the surface of the slide rod 33. The surface of the cleaning rod 34 contacts the surface of the filter rotating plate 16. The surface of the cleaning plate 35 contacts the surface of the anti-clogging plate 36. The bottom of the anti-clogging plate 36 contacts the surface of the filter disc 18. The inner wall of the collecting ring 37 contacts the outer wall of the filter disc 18. The inner wall of the rising slip ring 31 is slidably connected to the inner wall of the moving groove. The end of the slide rod 33 is slidably connected to the inner wall of the groove. It scrapes away the impurities accumulated on the anti-clogging plate 36 and pushes the impurities into the collecting ring 37. When the slide rod 33 slides outward, it pulls one end of the pull rod 32 outward in sync, while the other end of the pull rod 32 pulls... The moving slip ring 31 slides upward along the moving groove. The present invention relies on the rotating anti-clogging plate 36 to continuously collect impurities on the surface of the filter disc 18, avoiding the accumulation and clogging of the filter holes. The matching cleaning rod 34 and cleaning plate 35 can automatically clean the impurities attached to the surface of the filter rotating plate 16 and the anti-clogging plate 36 respectively. The cleaning rod 34 guides the impurities of the filter plate into the guide groove and finally into the collection ring 37. The cleaning plate 35 directly pushes the impurities collected by the anti-clogging plate to the collection ring 37 for unified collection. The present invention can effectively avoid the filter rotating plate 16 and the filter disc 18 from the decrease in filtration efficiency due to impurities clogging. It eliminates the need for frequent manual disassembly and cleaning, greatly reducing the labor intensity of manual operation and maintenance.

[0029] The vibration mechanism 50 includes a slip ring 51, a return spring 52 fixedly connected to the bottom of the slip ring 51, a limit ring 53 fixedly connected to the surface of the stirring rod 15, a compression bending plate 57 fixedly connected to the outer wall of the slip ring 51, a support frame 58 fixedly connected to the upper surface of the inner wall of the processing cylinder 2, and a force-bearing inclined block 59 fixedly connected to the bottom of the support frame 58. When the stirring rod 15 rotates, it synchronously drives the slip ring 51, the return spring 52, the limit ring 53, the lower push rod 54, and the impact rod 55. Driven rod 56 rotates together with extrusion plate 57. During rotation, extrusion plate 57 periodically contacts the inclined surface of force-bearing block 59. Due to the limiting effect of the inclined surface, extrusion plate 57 moves downward. The downward extrusion plate 57 pushes slip ring 51 to slide down along the outer wall of stirring rod 15, compressing reset spring 52 to make it contract. Slip ring 51 moves down and pushes one end of push rod 54 down. The other end of push rod 54 drives impact rod 55 to feed towards filter rotating plate 16 and hit the plate surface.

[0030] The end of the push rod 54 furthest from the impact rod 55 is hinged to the outer wall of the slip ring 51. The inner wall of the slip ring 51 is slidably connected to the surface of the stirring rod 15. The top of the limiting ring 53 contacts the bottom of the slip ring 51. The inner wall of the support frame 58 is rotatably connected to the upper surface of the rotating shaft 13. The end of the driven rod 56 furthest from the impact rod 55 is hinged to the outer wall of the slip ring 51. The inner wall of the return spring 52 contacts the surface of the stirring rod 15. When the impact rod 55 moves, it pulls the driven rod 56 to move synchronously. The driven rod 56 pulls the slip ring 51 upward in the opposite direction, further compressing the return spring 52. When the compression bending plate 57 rotates and disengages from the force-bearing inclined block 59, the return spring 52 releases its elastic force, causing the slip ring 51, limit ring 53, lower push rod 54, impact rod 55 and driven rod 56 to return to their original positions. Because the compression bending plate 57 continuously performs circular motion, it can intermittently contact the force-bearing inclined block 59, driving the impact rod 55 to periodically strike the filter rotating plate 16, causing the filter rotating plate 16 to continuously vibrate. This invention uses the intermittent impact of the impact rod 55 to make the surface of the filter rotating plate 16 vibrate, and relies on the vibration force to peel off the dirt attached to the surface of the filter plate, greatly improving the self-cleaning effect of the filter plate.

[0031] In use, the electroplating wastewater to be treated is first discharged into the treatment cylinder 2 through the inlet pipe 4. Then, the motor 3 is started to drive the gear disc 19 to rotate. The gear disc 19 meshes with the transmission gear ring 11 and rotates synchronously. The gear ring 11 drives the connecting plate 12 and the rotating shaft 13 to rotate together. The rotating shaft 13 synchronously drives the long rod 14 and the filter rotating plate 16 to rotate. When the long rod 14 rotates, it drives the stirring rod 15 to continuously stir the water in the cylinder, so as to promote the thorough mixing and reaction of the reagent and the electroplating wastewater. During the stirring process, suspended impurities in the water can be intercepted and attached to the surface of the filter rotating plate 16. While the filter rotating plate 16 is rotating, it drives the scraper 17 to rotate synchronously. The scraper 17 continuously scrapes off the dirt adhering to the inner wall of the treatment cylinder 2. The scraped impurities are collected in the collection ring 37 along the guide groove of the cylinder wall and collected. After initial treatment in the cylinder, the wastewater is further treated. The purified electroplating wastewater is discharged from the outlet pipe 5 and sent to the sedimentation tank 1. The wastewater undergoes secondary fine filtration when it flows through the filter disc 18 in the pipeline. This invention achieves full mixing and reaction of the reagent and wastewater through the stirring rod 15. Combined with the filter rotating plate 16 and filter disc 18, a multi-stage impurity filtration structure is formed, which greatly improves the impurity removal efficiency of electroplating wastewater. At the same time, the rotating scraper 17 automatically cleans the scale on the cylinder wall, eliminating the need for manual disassembly and cleaning, effectively improving the self-cleaning efficiency of the inner wall of the equipment and the continuity of the overall wastewater treatment. When the rotating shaft 13 and the filter rotating plate 16 rotate synchronously, they simultaneously drive the rising slip ring 31, pull rod 32, slide rod 33, cleaning rod 34, cleaning plate 35 and anti-clogging plate 36 to rotate together. During the operation of the equipment, the anti-clogging plate 36 rotates with the rotating shaft 13, which can collect the scale attached to the filter. Impurities trapped on the surface of the filter disc 18 are removed by centrifugal force generated during the rotation of the filter plate 16. This centrifugal force drives four sets of sliding rods 33 to slide along the grooves in a direction away from each other. As the sliding rods 33 move, they simultaneously push the cleaning rods 34 in the same direction away from each other, scraping away the impurities attached to the surface of the filter plate 16 and pushing the impurities to the guide groove. Simultaneously, the cleaning rods 34 move, driving the cleaning plate 35 to move synchronously, scraping away the impurities accumulated on the anti-clogging plate 36 and pushing the impurities into the collection ring 37. When the sliding rods 33 slide outward, they pull one end of the pull rod 32 outward, while the other end of the pull rod 32 pulls the rising slip ring 31 upward along the moving groove. This invention relies on the rotating anti-clogging plate 36 to continuously collect impurities on the surface of the filter disc 18, preventing filter holes from clogging. The cleaning rod 34 and cleaning plate 35, which are set together, can automatically clean the impurities attached to the surface of the filter rotating plate 16 and the anti-clogging plate 36, respectively. The cleaning rod 34 guides the impurities of the filter plate into the guide groove and finally into the collection ring 37. The cleaning plate 35 directly pushes the impurities collected by the anti-clogging plate to the collection ring 37 for unified collection. This invention can effectively avoid the decrease in filtration efficiency of the filter rotating plate 16 and filter disc 18 due to impurities clogging. It eliminates the need for frequent manual disassembly and cleaning, greatly reducing the labor intensity of manual operation and maintenance. When the stirring rod 15 rotates, it synchronously drives the slip ring 51, the return spring 52, the limit ring 53, the push rod 54, the impact rod 55, the driven rod 56, and the extrusion bending plate 57 to rotate together. During the rotation, the extrusion bending plate 57 periodically contacts the inclined surface of the force-bearing inclined block 59 and is limited by the inclined surface.The extrusion plate 57 moves downward, pushing the slip ring 51 down the outer wall of the stirring rod 15, compressing the return spring 52 and causing it to contract. Simultaneously, the downward movement of the slip ring 51 pushes one end of the lower push rod 54 downward, while the other end of the lower push rod 54 drives the impact rod 55 to advance towards the filter rotating plate 16 and strike the plate surface. When the impact rod 55 moves, it pulls the driven rod 56 to move synchronously. The driven rod 56 pulls the slip ring 51 upward in the opposite direction, further compressing the return spring 52. As the extrusion plate 57 rotates, it disengages from the force-bearing inclined block. After step 59, the return spring 52 releases its elastic force, causing the slip ring 51, limit ring 53, push rod 54, impact rod 55, and driven rod 56 to reset as a whole. Because the compression bending plate 57 continuously performs circular motion, it can intermittently contact the force-bearing inclined block 59, driving the impact rod 55 to periodically strike the filter rotating plate 16, causing the filter rotating plate 16 to continuously vibrate. This invention utilizes the intermittent impact of the impact rod 55 to vibrate the surface of the filter rotating plate 16, relying on the vibration force to peel off the dirt adhering to the filter plate surface, significantly improving the self-cleaning effect of the filter plate.
