Description

Technical Field

[0001] This utility model relates to the field of nickel recycling, specifically a high-efficiency and environmentally friendly nickel recycling device based on electroplating processing. Background Technology

[0002] In the electroplating industry, nickel recycling is not only a key link in realizing resource recycling, but also an important measure to reduce environmental pollution from nickel-containing wastewater and slag. To balance the efficiency and environmental friendliness of the recycling process, chemical recycling devices are widely used. Their core principle is to use chemical reactions to make nickel ions in wastewater form a precipitable or easily separated form, which has significant advantages such as low cost and simple operation.

[0003] However, current high-efficiency and environmentally friendly nickel recovery devices for electroplating still have significant limitations in actual operation. The conventional process of such devices is as follows: nickel-containing wastewater generated from electroplating is injected into the tank, an agent that can react with nickel ions is added, and the mixture is stirred to promote the precipitation of nickel ions. Finally, the precipitate is removed to complete the recovery. However, most devices require the treated wastewater to be discharged first, and then the sealing plate is opened to manually clean the precipitate with tools when removing the precipitated nickel. This operation requires stopping the mixing operation and is too cumbersome, which seriously affects the recovery efficiency. Therefore, in order to address the above problems, a high-efficiency and environmentally friendly nickel recovery device based on electroplating is proposed. Utility Model Content

[0007] Preferably, a limiting groove is formed on the inner wall of the end of the supporting shell, and a limiting plate is elastically connected to the inner wall of the end of the collecting shell by a spring. The end of the limiting plate is inserted into the middle of the limiting groove, and the outer wall of the limiting plate is slidably connected to the middle of the collecting shell. One end of the spring is fixedly connected to the other end of the limiting plate, and the other end of the spring is fixedly connected to the inner wall of the end of the collecting shell. A push plate is fixedly connected to the side wall of the limiting plate, and the end of the limiting plate is set as an inclined surface.

[0008] Preferably, the discharge assembly further includes a sealing strip, which is fixed to the outer wall of the baffle, and a sealing groove is provided on the inner wall of the bottom of the mixing tank, with the sealing strip contacting the middle of the sealing groove.

[0009] Preferably, the side wall of the collecting shell is provided with a second through groove, and the push plate is specifically fixed to the side wall of the limiting plate through the second through groove.

[0010] Preferably, the bottom of the cleaning plate is fixedly connected to a plug-in block, the top of the sliding plate is provided with a plug-in groove, the plug-in block is inserted into the middle of the plug-in groove, the outer wall of the plug-in block and the inner wall of the plug-in groove are both T-shaped, and the outer wall of the plug-in block and the inner wall of the plug-in groove are interference fit.

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.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail. This application discloses a high-efficiency and environmentally friendly nickel recycling device based on electroplating. (Refer to...) Figure 1 - Figure 3A high-efficiency and environmentally friendly nickel recycling device based on electroplating includes a support shell 2. A mixing tank 1 is fixedly connected to the inner wall of the top of the support shell 2. A mixing mechanism 6 is installed in the middle of the mixing tank 1. A feed pipe 7 is fixedly connected to the top of the mixing tank 1. A discharge pipe 8 is fixedly fixed at the eccentric part of the bottom of the mixing tank 1. The outer wall of the bottom of the discharge pipe 8 is fixedly connected to the middle of the support shell 2. A discharge assembly is provided on the inner wall of the bottom of the mixing tank 1. A collection shell 3 slides in the middle of the support shell 2. The discharge assembly includes a rotating rod 4, which is rotatably connected to the bottom of the mixing tank 1. The inner wall of the mixing tank 1 is rotatably connected to the inner wall of the top of the support shell 2. A baffle 41 is fixed to the outer wall of the rotating rod 4, and the baffle 41 rotates on the inner wall of the bottom of the mixing tank 1. A rectangular plate 43 is fixed to the outer wall of the rotating rod 4, and a bolt 44 is threadedly connected to the inner wall of the end of the rectangular plate 43. A threaded groove 21 is opened on the side wall of the top of the support shell 2, and the outer wall of the end of the bolt 44 is threadedly connected to the middle of the threaded groove 21. During operation, nickel wastewater is discharged into the middle of the mixing tank 1 through the feed pipe 7, and materials that react with nickel are placed into the mixing tank 1. The mixing mechanism 6 is then activated to stir the material, ensuring that the nickel reacts fully with the reacting materials and forms a precipitate. After the reaction is complete, the wastewater is discharged through the feed pipe 7. The specific operation methods described above are all existing technologies and can be implemented by those skilled in the art. As they are existing technologies, they will not be described in detail in this case. When it is necessary to discharge the nickel precipitate in the middle of the mixing tank 1, the bolt 44 can be rotated to disengage it from the middle of the threaded groove 21. Then, by pushing the bolt 44 against the rectangular plate 43, the rotating rod 4 is rotated. The rotating rod 4 will drive the baffle 41 to rotate. When the baffle 41 is open, the sediment in the middle of the mixing tank 1 will be discharged into the middle of the collection shell 3. After the discharge is completed, continue to rotate the rotating rod 4 to switch the upper and lower sides of the baffle 41 until the bolt 44 is aligned with another set of threaded grooves 21. Rotate the bolt 44 to the middle of the other set of threaded grooves 21. At this time, the next batch of nickel wastewater can be processed. There is no need for workers to repeatedly use tools to retrieve the precipitated nickel. Moreover, when retrieving the precipitated nickel, it does not affect the device's continued processing of nickel wastewater, thus improving the recovery efficiency.

[0019] Reference Figure 2 and Figure 4The top of the collection shell 3 is provided with a sliding groove 36, the middle of the sliding groove 36 is provided with a connecting groove 37, the side wall of the collection shell 3 is provided with a through groove 32, the middle of the sliding groove 36 is slidably connected to a sliding plate 52, the top of the sliding plate 52 contacts a cleaning plate 51, the top of the cleaning plate 51 slides on the bottom of the baffle 41, the bottom of the sliding plate 52 is fixedly connected to a spring 53, the bottom of the spring 53 is fixedly connected to the middle of the sliding groove 36. When the collection shell 3 is taken out from the middle of the support shell 2 during operation, the sliding plate 52 will push the cleaning plate 51 to contact the surface of the rotating rod 4 through the elasticity of the spring 53, ensuring that when the collection shell 3 moves, the cleaning plate 51 will scrape off the precipitated nickel adsorbed on the surface of the rotating rod 4, ensuring that the precipitated nickel can be fully cleaned and recycled, thus improving practicality. Reference Figure 1 - Figure 3 The inner wall of the supporting shell 2 has a limiting groove 22. The inner wall of the collecting shell 3 is elastically connected to a limiting plate 33 via a spring 34. The end of the limiting plate 33 is inserted into the middle of the limiting groove 22, and the outer wall of the limiting plate 33 is slidably connected to the middle of the collecting shell 3. One end of the spring 34 is fixed to the other end of the limiting plate 33, and the other end of the spring 34 is fixed to the inner wall of the collecting shell 3. A push plate 31 is fixed to the side wall of the limiting plate 33. The end of the limiting plate 33 is set as an inclined surface. During operation, by inserting the limiting plate 33 into the middle of the limiting groove 22, the stability of the collecting shell 3 in the middle of the supporting shell 2 is ensured. When it is necessary to remove the collecting shell 3 from the supporting shell 2, the limiting plate 33 can be inserted into the middle of the limiting groove 22. When the middle part of the support shell 2 is removed, the push plate 31 can be pushed to move the limiting plate 33, so that the limiting plate 33 is disengaged from the middle of the limiting groove 22. Then, the collection shell 3 can be pulled directly. When installing the collection shell 3, the collection shell 3 is directly inserted into the middle of the support shell 2. During the insertion process, the support shell 2 will be pushed along the inclined surface of the limiting plate 33 to move into the inner wall of the end of the collection shell 3. The limiting plate 33 will squeeze the spring 34 until the limiting plate 33 coincides with the limiting groove 22. At this time, the spring 34 will push the limiting plate 33 to reset through its own elasticity and insert it into the middle of the limiting groove 22. In this way, the disassembly and installation of the collection shell 3 are completed, which is quick and convenient and improves the recycling efficiency. Reference Figure 3 The material discharging assembly also includes a sealing strip 42, which is fixed to the outer wall of the baffle 41. The inner wall of the bottom of the mixing tank 1 is provided with a sealing groove 9, and the sealing strip 42 contacts the middle of the sealing groove 9. During operation, when the baffle 41 is closed, the sealing strip 42 will contact the middle of the sealing groove 9 to ensure the sealing performance of the closed baffle 41 and improve its practicality. When the baffle 41 is rotated, the sealing strip 42 will be squeezed and deformed, and will detach from the middle of the sealing groove 9. When the sealing strip 42 overlaps with the sealing groove 9 or completely detaches from the inner wall of the sealing groove 9, the sealing strip 42 will reset itself through its own elasticity. Reference Figure 3 The collecting shell 3 has a through groove 35 on its side wall. The push plate 31 is fixed to the side wall of the limiting plate 33 through the through groove 35. During operation, the through groove 35 ensures that the push plate 31 can only move horizontally, and can stably drive the limiting plate 33 to move horizontally, thus improving its practicality. Reference Figure 5 The bottom of the cleaning plate 51 is fixedly connected to a plug block 56, and the top of the sliding plate 52 is provided with a plug groove 57. The plug block 56 is inserted into the middle of the plug groove 57. The outer wall of the plug block 56 and the inner wall of the plug groove 57 are both T-shaped. The outer wall of the plug block 56 and the inner wall of the plug groove 57 are interference fit. During operation, after the cleaning plate 51 has been used for a period of time, when the collection shell 3 is taken out from the middle of the support shell 2, the cleaning plate 51 can be pushed to make the plug block 56 disengage from the middle of the plug groove 57. In this way, the cleaning plate 51 can be disassembled and maintained. During installation, the plug block 56 can be directly inserted into the middle of the plug groove 57. Reference Figure 2 - Figure 4 A rectangular block 55 is fixedly connected to the side wall of the sliding plate 52. The outer wall of the rectangular block 55 is slidably connected to the middle of the connecting groove 37. A rectangular strip 54 is fixedly connected to the side wall of the rectangular block 55. The outer wall of the rectangular strip 54 is slidably connected to the middle of the through groove 32. A connecting plate 5 is fixedly connected to the end of the rectangular strip 54. During operation, when the collection shell 3 is inserted into the middle of the support shell 2, it may be blocked by the sliding plate 52. At this time, the rectangular strip 54 and the rectangular block 55 can be moved by pushing the connecting plate 5, so that the sliding plate 52 moves accordingly and moves the cleaning plate 51, so that the top of the cleaning plate 51 is flush with the top of the collection shell 3. In this way, the collection shell 3 can be installed smoothly, which improves practicality.

[0020] Working principle: When it is necessary to discharge the nickel precipitate in the middle of the mixing tank 1, the bolt 44 can be rotated to disengage it from the middle of the threaded groove 21. Then, by pushing the bolt 44 and the rectangular plate 43, the rotating rod 4 is rotated. The rotating rod 4 will drive the baffle 41 to rotate. When the baffle 41 is opened, the precipitate in the middle of the mixing tank 1 will be discharged into the middle of the collection shell 3. After the discharge is completed, the rotating rod 4 is rotated again to switch the upper and lower sides of the baffle 41 until the bolt 44 is aligned with another set of threaded grooves 21. The bolt 44 is then rotated to the middle of the other set of threaded grooves 21. At this point, the next batch of nickel wastewater can be processed. There is no need for workers to repeatedly use tools to retrieve the precipitated nickel. Moreover, when retrieving the precipitated nickel, it does not affect the continued processing of nickel wastewater by the device, thus improving the recovery efficiency.

[0021] When it is necessary to remove the collection shell 3 from the middle of the support shell 2, the push plate 31 can be pushed to move the limiting plate 33, causing the limiting plate 33 to disengage from the middle of the limiting groove 22. Then, the collection shell 3 can be pulled directly. When installing the collection shell 3, the collection shell 3 is directly inserted into the middle of the support shell 2. During the insertion process, the support shell 2 will be pushed along the inclined surface of the limiting plate 33 to move into the inner wall of the end of the collection shell 3. The limiting plate 33 will squeeze the spring 34 until the limiting plate 33 coincides with the limiting groove 22. At this time, the spring 34 will push the limiting plate 33 to reset through its own elasticity and insert it into the middle of the limiting groove 22. This completes the disassembly and installation of the collection shell 3, which is quick and convenient and improves the recycling efficiency.

[0022] When the collection shell 3 is removed from the middle of the support shell 2, the sliding plate 52 will push the cleaning plate 51 to contact the surface of the rotating rod 4 through the elasticity of the spring 53. This ensures that when the collection shell 3 moves, the cleaning plate 51 will scrape off the precipitated nickel adsorbed on the surface of the rotating rod 4, ensuring that the precipitated nickel can be fully cleaned and recycled, thus improving its practicality.
