[0002] Nickel sulfate is a green crystal with a tetragonal crystal system. It is readily soluble in water and slightly soluble in ethanol and methanol. Its aqueous solution is acidic and slightly soluble in acids and ammonia. It is toxic and is mainly used in the electroplating industry. It is the main nickel salt for electroplating nickel and electroless nickel plating, and is also the source of metallic nickel ions. It can dissociate nickel ions and sulfate ions during the electroplating process.

[0003] The currently published patent, CN216418377U, discloses a nickel sulfate crystallization device that facilitates pre-cooling. This nickel sulfate crystallization device is equipped with an air-cooling heat dissipation mechanism and a water-cooling heat dissipation mechanism. Before the heated nickel sulfate solution flows into the concentration tank, it can be cooled twice by a combination of air cooling and water cooling. The heat transfer is uniform and the cooling efficiency is high, which improves the production efficiency of the nickel sulfate crystallization device to a certain extent.

[0004] Based on the above search results, the nickel sulfate crystallization equipment has uniform heat transfer and high cooling efficiency, which improves the production efficiency of the nickel sulfate crystallization equipment to a certain extent. However, during the freezing crystallization process of nickel sulfate, due to the low temperature of the inner wall of the storage tank, the crystals precipitated by nickel sulfate tend to adhere to the inner wall of the storage tank and are difficult to collect fully, resulting in the loss of finished nickel sulfate, waste of raw materials, and affecting the crystallization efficiency of nickel sulfate. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a stirring device in the process of nickel sulfate crystallization.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0025] Please see Figure 1-4This utility model provides a technical solution: a stirring device in the process of nickel sulfate crystallization, including a stirring tank 1 and a stirring tank inner wall cleaning device. A conical feed hopper 2 is fixedly connected to the top of the stirring tank 1, and a discharge bend 3 is fixedly connected to the bottom of the stirring tank 1. The stirring tank inner wall cleaning device includes a drive motor 4, a rotating rod 5, five stirring shafts 6, five cleaning scrapers 7, and five stirring inclined rods 8. The drive motor 4 is fixedly installed on the top of the stirring tank 1. The rotating rod 5 is rotatably connected to the inside of the stirring tank 1. The upper end of the rotating rod 5 is fixedly connected to the output end of the drive motor 4. The five stirring shafts 6 are all fixedly connected to the surface of the rotating rod 5. The five cleaning scrapers 7 are respectively fixedly connected to one end of the five stirring shafts 6. The five cleaning scrapers 7 are all in contact with the inner wall of the stirring tank 1, and the cleaning scrapers 7 on the left and right sides are alternately distributed in the vertical direction. The five stirring inclined rods 8 are respectively fixedly connected to the inside of the five stirring shafts 6.

[0026] Three support rods 9 are fixedly connected to the bottom of the mixing tank 1. A water storage tank 10 is fixedly connected to the lower end of the three support rods 9. A water pump 11 is fixedly installed in the water storage tank 10. A water pump pipe 12 is fixedly installed at the water pump 11. The end of the water pump pipe 12 away from the water pump 11 extends into the interior of the water storage tank 10. A drain pipe 13 is fixedly installed at the drain end of the water pump 11. A spiral cooling pipe 14 is fixedly connected to the surface of the mixing tank 1. The end of the drain pipe 13 away from the water pump 11 is fixedly connected to the lower end of the spiral cooling pipe 14. A return bend pipe 15 is fixedly connected to the upper end of the spiral cooling pipe 14. The lower end of the return bend pipe 15 extends into the interior of the water storage tank 10.

[0027] Workers can pour nickel sulfate into the mixing tank 1 through the conical feed hopper 2. After starting the water pump 11, the water pump 11 can draw water stored in the water storage tank 10 through the water pumping pipe 12 and discharge the cooling water into the spiral cooling pipe 14 through the drain pipe 13. The spiral cooling pipe 14 and the cooling water inside it can then cool the mixing tank 1, thereby accelerating the cooling speed of the nickel sulfate inside the mixing tank 1. After the cooling water flows to the upper end of the spiral cooling pipe 14, it can flow back into the water storage tank 10 through the return bend 15, thus achieving the recycling of the cooling water.

[0028] At this time, nickel sulfate cools and crystallizes. After the staff starts the drive motor 4, the output end of the drive motor 4 rotates, which drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the five stirring shafts 6 to rotate and stir the nickel sulfate. The rotation of the stirring shafts 6 also drives the stirring bar 8 to rotate and stir the nickel sulfate. Generally, the stirring action improves the uniformity of the cooling of nickel sulfate inside the stirring tank 1. The rotation of the five stirring shafts 6 can also drive the five cleaning scrapers 7 to rotate and clean the nickel sulfate crystals precipitated on the inner wall of the stirring tank 1. The nickel sulfate crystals move downward to the bottom wall of the stirring tank 1, which is convenient for discharge to the outside through the discharge bend 3. The five cleaning scrapers 7 scrape off the nickel sulfate crystals precipitated on the inner wall of the stirring tank 1, preventing the nickel sulfate crystals from sticking to the inner wall of the stirring tank 1. This makes it easier for the staff to collect the nickel sulfate crystals, avoid the loss of finished nickel sulfate, prevent raw material waste, and improve the crystallization efficiency of nickel sulfate.
