[0002] Nickelous oxide is an important inorganic compound, widely used in batteries, catalysts, magnetic materials and other fields. Its production process mainly includes two methods: wet method and dry method.

[0003] The main steps of wet production of nickelous oxide include preparation of nickel salt solution, precipitation of nickel hydroxide, precipitation of nickelous oxide, washing, drying and other processes. First, nickel salt is added to water, heated and stirred to dissolve it, and a nickel salt solution is obtained. Then sodium hydroxide or ammonium hydroxide is added to react with nickel ions to precipitate nickel hydroxide. Then an excess of sodium hydroxide or ammonium hydroxide is added to react with nickel hydroxide to form nickelous oxide precipitate. Finally, the precipitate is washed and dried several times to obtain pure nickelous oxide powder.

[0004] Since the preparation process of nickelous oxide usually requires high-temperature heating treatment, a cooling device is often required to cool down raw materials such as nickelous oxide to ensure the stability of the reaction system, so as to control the reaction temperature and keep the temperature in the reactor stable. At present, most cooling devices usually store and cool the raw materials such as nickelous oxide in batches when the reaction is completed.

At the same time, the static accumulation of materials is prone to uneven cooling such as local overcooling. In addition, the cooling devices in the prior art usually have a single function, high energy consumption and certain limitations in use.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] See also Figure 1-3The present embodiment relates to a circulating cooling device for nickelous oxide processing, comprising a fixed frame 1 and a storage bin 2, wherein the storage bin 2 is fixed on the fixed frame 1, and is provided with a feed inlet 21 on its top, a discharge outlet 22 on its bottom, and an adaptable rotating frame 3 is arranged for rotation inside the fixed frame 1, wherein the rotating frame 3 comprises a turntable 31 and a through pipe 32, wherein the turntable 31 is adapted to rotate at both ends inside the storage bin 2, wherein a ventilation duct 311 is arranged inside the turntable 31 and is connected to a plurality of mounting holes 312 arranged on the side wall, wherein the through pipe 32 is provided with a plurality of groups and is distributed in an array and penetrates through a plurality of mounting holes 312 inside the storage bin 2 and is adapted to connect the turntables 31 on both sides, wherein a driving component 4 and a compressor 5 are fixed on both sides of the fixed frame 1, respectively, wherein the driving component 4 is connected to the turntable 31 on one side of the rotating frame 3 inside the storage bin 2 and drives it to rotate, and the compressor 5 is arranged on the turntable 31 on the other side of the rotating frame 3 and is connected to the ventilation duct 311 arranged inside the turntable 31.

[0021] Specifically in this embodiment, the specific structure of this cooling device can be seen in Figure 1As shown, nickelous oxide or other reaction raw material powders that need to be cooled after high-temperature heating treatment can be added into the storage bin 2 through the feed port 21 provided above the storage bin 2. After the raw materials are added, the driving component 4 provided on the fixed frame 1 works, thereby driving the rotating frame 3 inside the storage bin 2 to rotate, and the raw materials in the discharge bin are continuously stirred through the multiple groups of through pipes 32 distributed in an array under the rotation of the rotating frame 3. At the same time, the compressor 5 provided on the fixed frame 1 works, and can continuously blow cold air into the ventilation duct 311 and the through pipe 32 provided in the turntable 31 of the rotating frame 3 through the rotating frame 3, so that the turntables 31 and the multiple groups of through pipes 32 on both sides of the rotating frame 3 have a lower temperature, thereby reducing the internal temperature of the storage bin 2, and driving the rotating frame 3 through the driving component 4 to continuously stir the raw materials inside the storage bin 2, and continuously cool the raw materials. The nickelous oxide or other reaction raw material powders cooled to a suitable temperature can be discharged through the discharge port 22 provided below the storage bin 2 to complete the cooling operation. This cooling device is driven by the driving component 4 to drive the rotating frame 3 to rotate, and the compressor 5 is designed to blow cold air through the rotating disk 31 and the through pipe 32 inside the storage bin 2, so that the batch of raw materials stored in the storage bin 2 is continuously stirred by the rotating frame 3, which has a better heat dissipation effect, and with the cooperation of the compressor 5, the raw material cooling time can be further shortened, and the energy loss can be reduced. At the same time, the internal raw materials are not prone to local overcooling and other uneven cooling phenomena under the continuous stirring of the rotating frame 3, which promotes the uniform cooling of the reaction raw materials such as nickelous oxide. In addition, during the cooling process, the storage material can be controlled by the control box 11 provided on the fixed frame 1. While the internal temperature of the bin 2 is monitored in real time, the speed of the driving component 4 can be adjusted and the compressor 5 can be controlled to adjust the temperature of its cold air, etc., which is convenient for operation and can make timely adjustments to abnormal situations that occur, further improving the operating stability of this cooling device. In addition, the inside of the storage bin 2 can be used to mix powder raw materials required for various reactions. Under the action of its driving component 4 and the internal rotating frame 3, the various raw materials stored in the storage bin 2 can be evenly mixed and fully cooled, so that the functions of this cooling device are diversified and can meet different usage requirements, improve work efficiency and save energy.

[0022] The driving component 4 drives the rotating frame 3 to rotate by a synchronous belt 42, and includes a driving motor 41, a synchronous belt 42 and a reducer 43. The reducer 43 is connected to the rotating frame 3 inside the storage bin 2. The driving motor 41 is connected to the reducer 43 through the synchronous belt 42 and drives the rotating frame 3 to rotate. The specific structure of the driving component 4 can be found in Figure 1As shown, the driving motor 41 works and drives the reducer 43 to work through the synchronous belt 42, and the reducer 43 drives the rotating frame 3 in the storage bin 2 to rotate. The driving method of indirectly driving the rotating frame 3 to rotate with the synchronous belt 42 has higher transmission efficiency. Compared with the traditional direct driving method of the driving motor 41, it can reduce energy loss and make the transmission smoother. The setting of the reducer 43 can reduce the power required for the driving motor 41 to start and stop, and can further adjust the transmission ratio, thereby improving the operating stability of this driving component 4, and can play a certain protective role on the equipment, reducing the probability of equipment damage while extending a certain service life.

When the circulating pump 8 works, the treated cold water in the water tank 7 can be continuously circulated along the passage 23 of the side wall of the storage bin 2 through the surrounding plurality of water pipes 6, so as to further water-cool the storage bin 2. For the specific working process, please refer to Figure 3 As shown, this cooling device can accelerate the cooling rate of materials in the storage bin 2 through air cooling and water cooling, reduce the cooling time and further reduce the probability of uneven cooling such as local overcooling caused by raw materials adhering to the inner wall of the storage bin 2 for a long time, thereby ensuring the cooling effect and further improving the cooling efficiency in the production process.

At the same time, the outer layer 332 of the connecting shaft 33 is connected to the turntable 31 ventilation duct 311 and the compressor 5, so that the cold air can enter the outer layer 332 of the connecting shaft 33, further increasing the contact area between the raw material and the rotating frame 3, accelerating the cooling rate and improving the working stability.
