Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for treating electroplating nickel-chromium wastewater. Background Technology
[0002] Nickel-chromium electroplating wastewater is one of the most common types of wastewater in electroplating. It typically contains low levels of heavy metals. However, treating this type of wastewater using conventional electroplating wastewater treatment processes can lead to large amounts of chemicals and sludge due to the large volume of water being treated, potentially causing significant secondary pollution.
[0003] However, current electroplating nickel-chromium wastewater treatment devices require continuous addition of chemicals in the early stages, which leads to a large workload for staff. Furthermore, since the wastewater is constantly flowing when chemicals are added, the degree of chemical mixing affects the subsequent sludge sedimentation and water neutralization. Additionally, after the sedimented wastewater passes through the filter press, the filter residue inside the filter plates needs to be cleaned by the pusher to push the plates open one by one before the cleaning device can clean them. The cleaning and sewage discharge steps are repetitive, resulting in low work efficiency and failing to meet user needs. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a wastewater treatment device for nickel-chromium electroplating, which solves the problems mentioned in the background art. These problems arise because the wastewater is continuously flowing during the initial addition of chemicals, affecting the degree of chemical mixing and subsequent sludge sedimentation and water neutralization. Furthermore, after sedimentation, the wastewater passes through a filter press for compression and discharge, and the filter residue cleaning process requires the filter plates to be pushed open and discharged one by one by a pusher before the cleaning device can clean the plates. This repetitive operation of the cleaning and discharge steps leads to low work efficiency.

[0014] This invention provides a device for treating electroplating nickel-chromium wastewater, which has the following beneficial effects: This electroplating nickel-chromium wastewater treatment device, through the cooperation of water pumps, flocculation tanks, sedimentation tanks, and filter presses, sequentially neutralizes, strips, and filters out metallic impurities such as nickel and chromium contained in the wastewater. The streamlined process reduces the site requirements of the wastewater treatment device, meets the production needs of many related industries such as chemical, metal, or sewage processing plants, and is convenient to operate and highly efficient.
[0015] This electroplating nickel-chromium wastewater treatment device uses a stirring device in the flocculation tank to stir the wastewater while simultaneously using centrifugal force to discharge neutralizing agents. The faster the rotor rotates, the more agents are discharged, thus adjusting the amount of agents discharged. At the same time, the perforated structure in the triangular frames at the four corners of the flocculation tank can prevent the rotating water from forming eddies in the limited space of the flocculation tank and also prevent wastewater from overflowing from the inner wall.
[0016] This electroplating nickel-chromium wastewater treatment device, through the anti-condensation components on the inner wall of the flocculation tank bottom, can drive four small gears to rotate in sequence under the drive of the gears at the bottom of the rotating machine. The small gears then drive the large gears that mesh with them. The rotating large gear will cause the internal arc-shaped splicing plate to unfold and expose the channel. The air generated by the blower will be agitated at the bottom of the flocculation tank through the air outlets on the upper surface of the hollow ring pipe and the hollow arc pipe, preventing the neutralized impurities from settling and adhering to the bottom, thus increasing the difficulty of cleaning the equipment.
[0017] This electroplating nickel-chromium wastewater treatment device, through the improved structure of the filter press, allows wastewater to be fed into the filter plates from both ends of the filter press simultaneously, increasing the wastewater feeding speed. Furthermore, the baffle structure located below the filter plates prevents wastewater from dripping onto the conveyor belt after entering the filter plate grooves, keeping the surface of the conveyor belt dry, preventing impurities from adhering, and reducing the difficulty of cleaning.
[0018] This electroplating nickel-chromium wastewater treatment device achieves synchronous opening and closing through a connecting and stretching structure between multiple filter plates. When the push rod stretches the filter plate, the toothed plates on both sides of the front plate drive the toothed belt, thereby driving the top gear and push rod to rotate. The bevel gear on the side surface of the push rod drives the threaded rod with downward rotating teeth to rotate, allowing the high-pressure nozzle frame to fall synchronously to clean the grooves of the filtered filter plate. This allows the cleaning component and the filtration component to work together to accelerate the filtration efficiency. Attached Figure Description

[0027] In summary, this electroplating nickel-chromium wastewater treatment device works by pumping wastewater from the wastewater tank 1 using a water pump 2. The wastewater is then discharged into the flocculation tank 4 through the portal pipe 3. Next, the stirring motor 602 on the ramp 601 starts. As the output shaft of the stirring motor 602 drives the hexagonal hollow column 604 and the stirring rod 605 to rotate, the hollow tray 607 at the bottom of the reagent cylinder 603 is fitted onto the output shaft of the stirring motor 602, and the hollow tray 607 is connected to the hexagonal hollow column 604 via a bearing. Therefore, the neutralizing agent in the reagent cylinder 603 flows into the hexagonal hollow column 604 along the hollow tray 607. As the hexagonal hollow column 604 rotates with the output shaft of the stirring motor 602, the six rhombuses on the side of the hexagonal hollow column 604... The hollow rod 608 also begins to rotate. At this time, under the influence of centrifugal force, the sliding plate 6011 moves towards the fixed plate 6012 along the sliding tracks on both sides of the hollow rod 608. The movable tube 6010 located between the two sliding plates 6011 slides outward and pushes open the baffle 609, allowing the agent in the movable tube 6010 to mix with the sewage, thus accelerating the mixing efficiency. As the stirring motor 602 rotates faster, the amount of agent sprayed out increases, providing adjustment. The baffle 609 can also automatically close when the stirring motor 602 rotates at low speed or stops. At the same time, when the stirring gear 606 at the bottom of the stirring 605 rotates, it sequentially drives the small gears 705 above the four irregularly shaped discs 704 to rotate, and then the small gears 705 drive the large gear 706. When the large gear 706 rotates, the fixed rod 7011 pulls the corresponding arc-shaped splicing plate 7010 outward through the arc arm 7012, exposing the hole in the inner tube 709. The air generated by the blower 701 can then travel along the air duct 702 through the exhaust port 703 to the hole in the inner tube 709, and through the hole in the inner tube 709 to the top cover plate 7013 and the hollow arc tube 7014. Due to the airflow, the air can reach the four outward-facing hollow ring tubes 7015 in the fan opening 7016, and then through multiple air outlets 7017 to ensure a certain airflow at the bottom of the flocculation tank 4, so that the impurities after wastewater neutralization remain at the bottom of the tank but do not condense and adhere to the bottom in large quantities, reducing the cleaning pressure of the device. The neutralized wastewater enters the inner cylinder 90 through the Z-shaped pipe 8. Inside the 3rd chamber, after a certain amount of sedimentation, the rotating motor 907 on the upper surface of the placement plate 906 slowly starts, driving the rotating rod 908 and the four connected H-shaped brackets 909 to begin agitation. Due to the fluidity of the water, the water separated from the sedimentation above the inner cylinder 903 is discharged from the notch of the semi-circular ring 905 into the dividing layer between the inner cylinder 903 and the conical cylinder 901, and flows along the hook-shaped water pipe 1001 to the water pump 1002 and the transfer water tank 1003. Meanwhile, the sludge generated at the bottom of the inner cylinder 903 is swept away by multiple sweepers 9011 below the six inclined rods 9010 at the bottom of the rotating rod 908 and discharged into the sludge discharge pipe 904. The wastewater filtered by the sedimentation method is then processed by the power output of the water pump 1002 and the action of the booster 1102 of the first water pipe 1101.Wastewater is directed from the straight pipe 1005 and the cross-shaped fitting 1004 into the first water pipe 1101 and the second water pipe 1501, respectively. Wastewater in the first water pipe 1101 flows directly into the rear plate 1201, while wastewater in the second water pipe 1501 travels along the flexible hose 1502 to the fixed pipe 1503, then through the front support plate 1107 to the front plate 1202. The wastewater in both the first and fixed pipes simultaneously converges into the central movable square plate 1204, accelerating the wastewater filling efficiency. When the filter tank 1205 is full, and a large amount of dripping water falls onto the baffle plate 1114, the relay water tank assembly 10 is shut off to stop water injection. Water then flows through the rear plate 1201, front plate 1202, and movable square plate 1204. The filtered water in the filter tank 1205 of the movable square plate 1204 is discharged from the outlet pipe 1207 into the drainage tank 1110. When the water stops being discharged, the baffle plate 1114 is opened, and then the hydraulic press 1508 is started to allow gas to flow from the air supply pipe 1507 into the hydraulic telescopic rod 1505. This causes the hydraulic telescopic rod 1505 to extend outward, pulling the push plate 1504 and the front plate 1202 to move towards the front support plate 1107. Under the pull of the telescopic frame 1203, the multiple movable square plates 1204 are extended at equal distances, allowing the impurities in the filter tank 1205 of the rear plate 1201, front plate 1202, and movable square plates 1204 to fall onto the conveyor belt 1407. Under the pressure of gravity of the impurities, the conveyor belt 1407 moves along... On the rollers 1403 of the trapezoidal inclined frame 1402, impurities are prevented from falling outside the hollow frames 1401 on both sides without affecting the conveying. The start of the conveyor motor 1406 causes the drive shaft 1404 to rotate, which in turn causes the conveyor belt 1407 to rotate, carrying the impurities to the designated discharge point. When the hydraulic telescopic rod 1505 extends outward and pulls the push plate 1504 and the front plate 1202 to move towards the front support plate 1107, the rack structure on the top of the T-shaped frame 1208 on both sides of the front plate 1202 causes the rotating toothed belt 1302 to rotate. The rotating toothed belt 1302 causes the top gear 1316 and the top rod 1315 to rotate, and the bevel gear 1317 at the other end of the top rod 1315 to mesh and transmit power. The rotating gear 1313 rotates, which in turn drives the threaded rod 1311 to rotate. The pull rod 1312, located on the side surface of the threaded rod 1311, falls along with the top plate frame 1305. Meanwhile, the drop blocks 1304 at both ends of the top plate frame 1305 slide down the slide rails on both sides of the inner wall of the top frame 1303. When the high-pressure nozzle frame 1306 at the bottom of the top plate frame 1305 falls to the bottom of the rear plate 1201, front plate 1202, and movable square plate 1204, the baffle plate 1114 is closed, and the water supply tank 1308 at the top of the top frame 1303 is activated. Water is supplied through the water supply pipe 1307, and the high-pressure nozzle frame 1306 cleans the interior of the rear plate 1201, front plate 1202, and movable square plate 1204. After resetting, filtration continues.
