Description

Technical Field

[0001] This utility model relates to the field of nickel sulfate production technology, and in particular to a nickel sulfate crystallization device that is easy to pre-cool. Background Technology

[0002] Nickel sulfate is widely used in industries such as electroplating, batteries, printing and dyeing, and pharmaceuticals. The preparation methods of nickel sulfate include chemical methods and electrochemical methods. In its preparation process, it is generally necessary to fully mix the raw materials, followed by freeze crystallization and filtration to obtain the final nickel sulfate crystals. The inner wall of the storage tank in the existing nickel sulfate production equipment is in a low-temperature state. The crystals of nickel sulfate that precipitate are easy to adhere to the inner wall of the storage tank and are difficult to collect fully, resulting in the loss of finished nickel sulfate and waste of raw materials.

[0003] CN216149071U discloses a pre-coolable nickel sulfate crystallization device, including a crystallization tank and a filter box. The filter box has four fixed legs at its lower corners. The crystallization tank has a connecting pipe at its lower end that communicates with the interior of the tank. The lower end of the connecting pipe is fixedly connected to the middle of the upper surface of the filter box and communicates with the interior of the filter box. A condenser tube for cooling the crystallization tank is coiled on top of the crystallization tank. This device, through a first fixed frame, a first scraper, a second fixed frame, and a second scraper, can scrape off the crystals generated inside the crystallization tank during use, facilitating material discharge. However, directly cooling the solution through the condenser tube alone requires more time, and since the condenser tube is located externally, the condensation effect is generally poor, resulting in low working efficiency. Therefore, a pre-coolable nickel sulfate crystallization device is needed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a nickel sulfate crystallization device that is easy to pre-cool. This device can solve the problems that directly cooling the solution by means of a condenser tube requires more time, and that the condenser tube is located externally, resulting in a generally poor condensation effect and low working efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nickel sulfate crystallization device for easy pre-cooling, comprising a pre-cooling holding tank and a nickel sulfate solution pre-cooling device. The nickel sulfate solution pre-cooling device includes a water inlet pipe, a solution inlet pipe, a heat absorption layer, a condensing coil, a heat absorption plate, a water outlet pipe, and a solution holding chamber. The water inlet pipe is fixedly connected to the top of the pre-cooling holding tank, the solution inlet pipe is fixedly connected to the top of the pre-cooling holding tank, the heat absorption layer is fixedly connected to the inside of the pre-cooling holding tank, the condensing coil is fixedly connected to the inside of the pre-cooling holding tank, the top of the condensing coil is connected to the water inlet pipe, the heat absorption plate is fixedly connected to the outer surface of the condensing coil, and multiple heat absorption plates are equidistantly arranged on the outer surface of the equipment base. The water outlet pipe is fixedly connected to the bottom of the pre-cooling holding tank and is connected to the bottom of the condensing coil. The solution holding chamber is located inside the pre-cooling holding tank.

The rotating rod is rotatably connected to both the precooling container and the heat absorption layer, and a gear is fixedly sleeved on the outer surface of the rotating rod.

[0007] Preferably, the precooling container is rotatably connected to a rotating bracket inside, and multiple stirring blades are fixedly connected to the surface of the rotating bracket. The top of the rotating bracket is provided with a toothed groove, which meshes with a gear.

[0011] Preferably, a liquid outlet pipe B is fixedly connected to the surface of the protective shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This nickel sulfate crystallization equipment, which facilitates pre-cooling, enables the initial cooling of the nickel sulfate solution through a pre-cooling device, thereby aiding in subsequent crystallization and accelerating work efficiency.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a nickel sulfate crystallization device for easy pre-cooling, comprising a pre-cooling holding tank 1 and a nickel sulfate solution pre-cooling device. The nickel sulfate solution pre-cooling device includes a water inlet pipe 9, a solution inlet pipe 10, a heat absorption layer 11, a condensing coil 12, a heat absorption plate 13, a water outlet pipe 14, and a solution holding chamber 15. The water inlet pipe 9 is fixedly connected to the top of the pre-cooling holding tank 1, the solution inlet pipe 10 is fixedly connected to the top of the pre-cooling holding tank 1, and the heat absorption layer 11 is fixedly connected to the top of the pre-cooling holding tank 15. Inside the precooling chamber 1, the condensing coil 12 is fixedly connected to the inside of the precooling chamber 1. The top of the condensing coil 12 is connected to the water inlet pipe 9. The heat absorption plate 13 is fixedly connected to the outer surface of the condensing coil 12. There are multiple heat absorption plates 13, which are equidistantly arranged on the outer surface of the equipment base 2. The water outlet pipe 14 is fixedly connected to the bottom of the precooling chamber 1 and is connected to the bottom of the condensing coil 12. The solution holding chamber 15 is opened inside the precooling chamber 1.

[0025] Furthermore, a drive motor 17 is fixedly connected to the surface of the precooling container 1, and a rotating rod 18 is fixedly connected to the output end of the drive motor 17. The rotating rod 18 is rotatably connected to both the precooling container 1 and the heat absorption layer 11. A gear 19 is fixedly sleeved on the outer surface of the rotating rod 18. A rotating bracket 16 is rotatably connected inside the precooling container 1. Multiple stirring blades 21 are fixedly connected to the surface of the rotating bracket 16.

[0026] Furthermore, the high-temperature nickel sulfate solution is injected into the pre-cooling container 1 through the solution inlet pipe 10, and coolant is injected through the water inlet pipe 9.

The high-temperature nickel sulfate solution inside the pre-cooling container 1 is cooled by heat absorption through the condenser coil 12 and the heat absorption plate 13. The heat absorption layer 11 can absorb some heat. During the cooling process, the drive motor 17 is started to drive the rotating rod 18 and the gear 19 to rotate, which in turn drives the rotating bracket 16 to rotate. The rotation of the rotating bracket 16 enables the stirring blade 21 to stir the high-temperature nickel sulfate solution, so that the high-temperature nickel sulfate solution can fully contact the condenser coil 12 and the heat absorption plate 13, further improving the cooling efficiency. The cooled nickel sulfate solution is injected into the crystallization treatment box 7 through the water pump 4 to achieve crystallization. The specific internal structure of the crystallization treatment box 7 can be found in the announcement number CN216149071U.

[0027] Furthermore, the nickel sulfate solution precooling device enables preliminary cooling of the nickel sulfate solution, which helps in subsequent crystallization and speeds up the work. The stirring blade 21 allows the nickel sulfate solution precooling device to fully contact the condenser coil 12 and the heat absorption plate 13, improving the cooling speed. This solves the problems of directly cooling the solution through the condenser coil alone, which requires more time and has an external condenser coil, resulting in a generally poor condensation effect and low work efficiency.
