Description

Technical Field

[0001] The utility model relates to the technical field of electroplating solution recovery, and particularly relates to a device for recovering and treating electroplating nickel sulfate. Background Art

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals by using the electrolysis principle. It is a process of using electrolysis to make the surface of metal or other material parts adhere to a metal film, so as to prevent metal oxidation (such as rust). Nickel sulfate is the main salt that supplies nickel ions in the electroplating solution. Its concentration affects the cathode current efficiency and the performance of the coating. The key technologies for recovering electroplating nickel sulfate mainly include the ion exchange method. The main steps of this method include adjusting the pH value to an appropriate range to remove metals, but the pH value must be kept below 6 to prevent the formation of metal oxides and hydroxides precipitates. In addition, the resin used has a higher affinity for nickel, and its selectivity order is Ni>Zn>Co>Mg>Ca>Na. During the recovery process, nickel is first exchanged from the resin using hydrochloric acid or sulfuric acid, and then the resin is converted to the sodium form to complete the regeneration process.

[0003] A nickel recovery and treatment system for nickel-containing wastewater with the publication number CN216737830U includes a raw water tank, a bag filter, a resin tank with a nickel adsorption column inside, a regeneration system, and a PLC control system. The bottom of the raw water tank is provided with a water outlet connected to the water inlet of the bag filter, and the upper end of the resin tank is provided with a water inlet connected to the water outlet of the bag filter. The regeneration system includes a regeneration acid tank. The resin tank is provided with a sulfuric acid inlet connected to the regeneration acid tank. The resin tank is provided with a neutral nickel sulfate outlet, an acidic nickel sulfate outlet, and an acidic tail liquid outlet. After the nickel adsorption column is saturated, it is regenerated with sulfuric acid. The neutral nickel sulfate produced during regeneration is transported to the electroplating tank for recycling. The regenerated acidic nickel sulfate is adjusted to pH and then returned to the raw water tank for recirculation. The regenerated acidic tail liquid is used for repeated regeneration. The structure of the utility model is reasonably designed, the recovery effect is good, there is basically no loss of nickel, and it solves the recycling of heavy metal ions nickel in electroplating nickel rinse liquid, reduces production costs, reduces pollution emissions and resource waste.

[0004] The above technical solution uses a resin tank to realize the treatment of nickel ions in the electroplating solution. However, after the resin adsorbs a certain amount of nickel ions, it needs to be regenerated to restore its adsorption capacity. The process of resin regeneration and restoration will have a certain impact on the treatment efficiency of the electroplating solution, which is not conducive to the continuous recovery and treatment of the electroplating solution.

[0005] Therefore, it is necessary to invent a device for recovering and treating electroplating nickel sulfate to solve the above problems. Summary of the Utility Model

A movable rod 7 is inserted into the inside of the jack 6. The bottom end of the movable rod 7 is fixedly provided with a storage tank 8;

[0024] More specifically, there are two storage bins 8, and the two storage bins 8 are respectively arranged on both sides of the partition plate 2. A plurality of through holes are penetrated through the outer side wall of the storage bin 8, and a cover plate 9 is fixedly arranged at the top end of the storage bin 8 through bolts. The storage bin 8 can store the resin to facilitate the electroplating solution recovery work;

[0025] Moreover, a transmission plate 10 is fixedly arranged at the top end of the movable rod 7, and a spring 11 is arranged between the transmission plate 10 and the support plate 5. A driving plate 12 is arranged above the transmission plate 10. Hemispherical bumps 13 are arranged in a surrounding manner on the sides of the driving plate 12 and the transmission plate 10 close to each other. An installation plate 14 is fixedly arranged above the support plate 5. A driving motor 15 is fixedly arranged in the middle of the upper surface of the installation plate 14, and the output shaft of the driving motor 15 is fixedly connected with the middle of the driving plate 12.

[0026] Furthermore, a handle 16 is fixedly arranged on the upper surface of the installation plate 14. The arrangement of the handle 16 facilitates the user to pull the installation plate 14 to adjust the position of the storage bin 8;

[0027] At the same time, feeding pipes 17 are fixedly arranged at both top ends of the treatment barrel 1, and two discharge pipes corresponding to the feeding pipes 17 are penetrated through the bottom end of the treatment barrel 1.

[0029] The working principle of the present utility model:

[0030] When this device is in use, the electroplating solution to be recycled and the reducing solution for resin regeneration and reduction are respectively put into the interior of the treatment barrel 1 through two feed pipes 17. Then, the resin that adsorbs nickel ions in the electroplating solution is put into the storage bin 8, and the resin is restricted in the storage bin 8 through the cover plate 9. At this time, the resin in the storage bin 8 reacts with the nickel ions in the electroplating solution to adsorb the nickel ions, and other ions pass through the resin. This process can effectively separate the nickel ions from the wastewater. The wastewater after separating the nickel ions can be discharged through the discharge pipe at the bottom of the treatment barrel 1. After the resin is saturated with adsorbing a certain amount of nickel ions, pull the handle 16 upward, so that the handle 16 drives the mounting plate 14 and the support plate 5 to move upward. The support plate 5 drives the storage bin 8 to move upward through the movable rod 7, so that the storage bin 8 moves above the partition plate 2. At this time, the slider 18 at the bottom of the insertion rod 4 on the lower surface of the support plate 5 moves into the communication groove 20 at the top of the sliding groove 19. At this time, the handle 16 can be rotated so that the two storage bins 8 rotate and change positions. After the positions of the two storage bins 8 are switched, the slider 18 moves into the corresponding sliding groove 19. At this time, release the handle 16 so that the two storage bins 8 are respectively inserted into both sides of the partition plate 2. At this time, the switching of the resin between the nickel ion absorption state and the reduction and regeneration state can be realized;

[0031] During the working process of the device, the driving motor 15 drives the driving plate 12 to rotate, the driving plate 12 drives the convex block 13 to move, and the convex blocks 13 between the driving plate 12 and the transmission plate 10 squeeze each other, so that the transmission plate 10 moves up and down, thereby driving the storage bin 8 to drive the resin to move up and down, so as to improve the efficiency of the resin to adsorb nickel ions and the reduction and regeneration efficiency, thereby improving the working efficiency of the device.
