[0002] Sodium ion battery is one of the important technical development paths in the power battery and energy storage field due to its good electrochemical performance at low temperature, low content of rare and precious metals, and significant reduction in cost. Nickel protoxide is a raw material for the positive electrode of sodium ion battery. In order to seize market opportunities and cultivate future industries, large-scale production of battery grade nickel protoxide is the only way for the high-quality development of enterprises. The current mainstream process route for industrial production of nickel protoxide is spray pyrolysis, screening, slurry, water washing, centrifugation, drying, packaging and other processes. Due to the influence of the physical and chemical properties of nickel protoxide, during the material conveying process in the drying and packaging processes, due to the different moisture contents of the material, the material is prone to agglomeration, moisture absorption and high viscosity, etc. The material conveying device is blocked, the feeding screw slips and idles, the power device is locked and stops, and other faults occur frequently, which causes the production operation to be unable to continue. Therefore, it is very important to solve the problem of frequent faults and low efficiency of the material conveying device in order to fully utilize the designed production capacity of the production line and improve the economic efficiency of the enterprise.

DETAILED DESCRIPTION

[0014] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following is in conjunction with the drawing and example, and the utility model is further detailed.

[0015] As Figs. 1-3 The working process and principle of the utility model are as follows: in the nickel protoxide packaging process, the material enters the material bin 4 from the feed inlet 3. Since the nickel protoxide is easy to absorb moisture, the material flowability is poor, and is easy to bond, causing the material to bond on the inner wall of the material bin 4 and block at the bottom of the material bin 4, at this time, the reverse push type spiral belt stirring 5 driven by the stirring motor 1 and the stirring reduction 2 stirs and scatters the material through the spiral belt support 5-2 and the spiral belt 5-3, and the reverse push spiral 5-4 upwardly conveys the material accumulated at the bottom of the material bin 4, solving the problem of material blocking in the material bin 4. Then, the material enters the conveying pipe 6, and the double-sided zigzag double helix 7 and 8 driven by the gear 9, the spiral motor 11 and the spiral reduction 10 convey the material. Since the material is easy to bond to the inner wall of the conveying pipe 6, causing the double-sided zigzag double helix 7 and 8 to be deadlocked and stopped, and the spiral is easy to skid and idle in the material, causing the conveying to be interrupted, at this time, the material bonded to the inner wall of the conveying pipe 6 is damaged through the design of the zigzag edges on both sides of the spiral blade, preventing the material from being accumulated and blocked, solving the problem of the spiral being deadlocked and stopped, and since the design of the shaftless spiral, when the spiral skids and idles, the material continues to be conveyed forward through the shaftless area.

[0016] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. It should be noted that other equivalent improvements can be made by those of ordinary skill in the art under the technical inspiration provided by the present application, and all can achieve the purpose of the present application and should be considered as the protection scope of the present application.
