DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a purification device for nickel-cobalt sulfate solution, including a reaction tank 1, a tank cover 2 is installed on the top of the reaction tank 1, a storage component 3 and a feed pipe 4 are respectively arranged on the top of the tank cover 2, a filter plate 5 is installed inside the reaction tank 1, a reaction mechanism 6 is arranged on the top of the filter plate 5, and a discharge pipe 7 is arranged at the bottom of the reaction tank 1; wherein the reaction mechanism 6 includes a rotating shaft 61 rotatably installed at the bottom inside the reaction tank 1 through a bearing, the bottom of the reaction tank 1 is fixed to the bottom of the rotating shaft 61 through a driving part, the top of the rotating shaft 61 penetrates inside the filter plate 5 and is fixedly connected with a centrifugal filter cylinder 62, a fixed shaft 63 is rotatably connected inside the rotating shaft 61 through a bearing, a partition plate 64 is fixedly connected to the surface of the fixed shaft 63, the partition plate 64 fits inside the rotating shaft 61, and by rotating through the driving part, the rotating shaft 61 can be rotated. Under the rotation of the rotating shaft 61, the centrifugal filter cylinder 62 can be rotated. Since the fixed shaft 63 is rotatably installed inside the rotating shaft 61 through a bearing, the partition plate 64 fixed by the fixed shaft 63 will not rotate.

[0023] Supplementary note, the driving part is a motor.

[0024] According to Figure 2 It can be known that the feed pipe 4 includes a liquid inlet pipe 41 fixed to the top of the tank cover 2, an annular pipe 42 is connected to the end of the liquid inlet pipe 41, the annular pipe 42 is fixed to the inner top wall of the tank cover 2, and a plurality of nozzles 43 are fixedly connected to the surface of the annular pipe 42. With the setting of the liquid inlet pipe 41, the nickel-cobalt sulfate solution can be put in, then the nickel-cobalt sulfate solution can be dispersed through the annular pipe 42, and finally the nickel-cobalt sulfate solution is dispersed and sprayed into the reaction tank 1 through the nozzles 43.

[0025] According to Figure 2 It can be known that the storage component 3 includes a connecting pipe 31 fixed to the top of the tank cover 2, a storage cylinder 32 is fixedly connected to the top of the connecting pipe 31, and a flow valve is fixedly connected to the surface of the connecting pipe 31. With the setting of the storage cylinder 32 at the top of the connecting pipe 31, the sodium fluoride powder can be stored inside the storage cylinder 32, and then the quantity of the discharged sodium fluoride powder can be accurately controlled through the flow valve, so as to better react the sodium fluoride powder with the nickel-cobalt sulfate solution for purification work.

[0026] According to Figure 4It can be seen that the inlet pipe 41 is annularly arranged around the rotating shaft 61. By arranging the inlet pipe 41 annularly, the nickel sulfate solution to be purified can be sprayed around the centrifugal filter cylinder 62.

[0027] According to Figure 3 It can be seen that the number of discharge pipes 7 is set in two groups, and control valves are fixedly connected to the surfaces of the two discharge pipes 7. With the two - group setting of the discharge pipes 7, the purified nickel cobalt sulfate solution can be discharged faster. And with the setting of one - way valves, the on - off process inside the two discharge pipes 7 can be controlled.

[0028] According to Figure 2 and Figure 4 It can be seen that a cleaning brush plate 65 is fixedly connected to the bottom of the centrifugal filter cylinder 62. The cleaning brush plate 65 is located directly above the filter plate 5. Since the cleaning brush plate 65 is fixed to the bottom of the centrifugal filter cylinder 62, when the centrifugal filter cylinder 62 rotates, it can drive the cleaning brush plate 65 to rotate synchronously, thereby cleaning the top of the filter plate 5 to prevent impurity accumulation from affecting the purification effect of the nickel cobalt sulfate solution.

[0029] The working principle of the present utility model: When in use, first, the filling cover 2 is installed on the top of the reaction tank 1. Then, the storage component 3 is used to store the sodium fluoride powder, and the feed pipe 4 is used to put the nickel sulfate solution into the reaction tank 1. Under the setting of the reaction mechanism 6, the centrifugal filter cylinder 62 can be rotated by the rotating shaft 61, so that the sodium fluoride powder can be put into the centrifugal filter cylinder 62. Then, under the high - speed rotation of the centrifugal filter cylinder 62, the sodium fluoride powder can be thrown out to fully mix with the nickel sulfate solution in the reaction tank 1. And under the action of high - speed centrifugal force of the centrifugal filter cylinder 62, the flow rate of the nickel sulfate solution is relatively increased, thereby strengthening the contact area and contact effect between the nickel sulfate solution and the sodium fluoride powder. And when the centrifugal filter cylinder 62 rotates at high speed, the partition plate 64 fixed by the internal fixed shaft 63 will not rotate, thereby cleaning the sodium fluoride powder inside the centrifugal filter cylinder 62, making the effect of throwing out the sodium fluoride powder better. With the setting of the filter plate 5, it can filter the purified nickel sulfate solution, and the filtered nickel sulfate solution is discharged through the discharge pipe 7.
