Description

A nickel chloride cooling crystallization apparatus Technical Field

[0001] This utility model relates to the field of nickel chloride cooling crystallization technology, and in particular to a nickel chloride cooling crystallization device. Background Technology

[0002] The traditional method for crystallizing salt products involves concentrating the solution to a certain density, placing it in a crystallization device, and then cooling it with cooling water to achieve low-temperature crystallization. After crystallization, liquid-solid separation is performed to produce the product. For nickel chloride crystallization, seed crystals are added when the temperature of the nickel chloride solution is controlled at 50℃~55℃. The solution begins to crystallize under the action of the seed crystals. The solution temperature is then lowered to 40℃~45℃ and held for 3~4 hours. Finally, the temperature is lowered to 30℃ to produce a large number of crystals.

[0003] Existing nickel chloride cooling crystallization devices typically use a reaction tank to stir the nickel chloride solution. After thorough stirring, the nickel chloride solution is cooled to a suitable temperature, and then crystallization begins under the action of seed crystals.

[0056] The rotating motor 13 is fixedly connected to the upper surface of the horizontal plate of the positioning frame 9, and the rotating output shaft of the rotating motor 13 rotates through the lower surface of the horizontal plate of the positioning frame 9.

[0057] The vent pipe 5 is fixedly connected to the upper surface of the cover 7, and the vent pipe 5 is connected to the inside of the cover 7.

[0058] The support rod 14 is fixedly connected to the rotating output shaft of the rotating motor 13.

[0059] Furthermore, the first gear 11 is fixedly sleeved on the outer surface of the support rod 14;

[0060] Among them, the lower end of the support rod 14 rotates through the lower surface of the cover 7;

[0061] Among them, the two rotating rods 16 are rotatably sleeved on the cover 7 through bearings;

[0062] Among them, the two second gears 12 are fixedly connected to the upper ends of the two rotating rods 16;

[0063] Among them, the two second gears 12 are meshed with the first gear 11.

[0070] The collecting ring frame 10 is slidably connected to the inner wall of the reaction vessel 3.

[0071] Furthermore, the scraper ring 22 is fixedly connected to the upper surface of the collection ring frame 10, and the outer surface of the scraper ring 22 is in contact with and slidably connected to the inner wall of the reaction vessel 3.

The control panel, display screen and heating plate are existing technologies in the publicly disclosed patent: CN202121323404.6 A high-efficiency polymerization reaction device for nickel chloride, and will not be described in detail here.

[0076] Furthermore, during use, the electric actuator 8 is activated, causing the support block 6 to move downwards, thereby causing the cover 7 to close with the upper side of the reaction vessel 3. During this process, the positioning block 21 is also slid into the positioning groove 20, and the collecting ring frame 10 and scraper ring 22 are slid into the reaction vessel 3. The process stops when the electric actuator 8 moves the collecting ring frame 10 downwards until the lower surface of the collecting ring frame 10 is in contact with the bottom wall of the reaction vessel 3.

[0077] When the rotating motor 13 is started, it drives the support rod 14 to rotate, which in turn drives the first stirring rod 15 and the first gear 11 to rotate simultaneously. The first stirring rod 15 stirs the nickel chloride crystallizing liquid raw material in the reaction tank 3, while the first gear 11 drives the two second gears 12 to rotate, which in turn drives the two rotating rods 16 to rotate simultaneously, which in turn drives the second stirring rod 17 to rotate simultaneously. The second stirring rod 17 stirs and mixes the nickel chloride crystallizing liquid raw material in the reaction tank 3. The stirring directions of the first stirring rod 15 and the second stirring rod 17 are opposite, which improves the mixing effect of the nickel chloride crystallizing liquid raw material, improves the mixing efficiency of the nickel chloride crystallizing liquid raw material, and improves the efficiency of nickel chloride crystallization, thereby increasing the working efficiency and practicality of the nickel chloride cooling crystallization device.

[0078] Furthermore, because the positioning chute 20 is slidably connected to the positioning block 21, the collecting ring frame 10, the filter screen 19, and the scraper ring 22 will not rotate. When the temperature of the nickel chloride crystallizing liquid drops to a certain temperature, a large number of crystals will be produced after the nickel chloride crystallizing liquid cools down. At this time, the electric push rod 8 is activated. The electric push rod 8 drives the support block 6 and the cover 7 to move upward, which in turn drives the collecting ring frame 10, the filter screen 19, and the scraper ring 22 to move upward. The upward movement of the scraper ring 22 scrapes the crystals on the inner wall of the reaction tank 3 into the collecting ring frame 10, while the upward movement of the filter screen 19 can scoop the crystals upward, thereby achieving solid-liquid separation. The liquid can be discharged from the reaction tank 3 through the liquid outlet pipe 4. Thus, this scheme can achieve solid-liquid separation of nickel chloride. The solid-liquid separation is efficient, simple, flexible, and more labor-saving and efficient, thereby improving the practicality of the nickel chloride cooling crystallization device.
