The battery may include a cadmium nickel battery, a hydrogen nickel battery, a lithium ion battery, a secondary alkaline zinc manganese battery, and the like. A large amount of powder is required during battery processing, and the powder is mixed with a solvent to form a slurry before powder coating is performed. The production of the slurry requires a plasma homogenization process, which requires the addition of various raw materials into a refiner for pulping.
The refiner can generate a large amount of heat in the working process, and for production safety, shutdown and cooling are often required, so that the production efficiency is not improved. In the related art, a scheme of designing a cooling system in a refiner is also available, such as a high-speed refiner with a patent number of CN216094125U, the refiner is provided with a first cooling cavity and a second cooling cavity which are arranged in a stirring cavity and a discharging cavity, and is communicated with a second cooling liquid inlet and a second cooling liquid outlet which are arranged at the bottom of a cooling tank through a pipeline, so that the cooling system is cooled down through cooling liquid, the equipment temperature is ensured to be constant, the shutdown cooling is not needed, the working efficiency is improved, and meanwhile, a stirring sheet with an arc inclined design and a dispersion disc with a conical surface at the top are adopted, so that the slurry is not easy to adhere to the dispersion disc while being fully stirred, the manual cleaning is not needed, and the production cost is reduced.
However, the cooling system of the pulping machine does not have a good cooling effect on the main shaft connected with the motor, and the main shaft still generates a large amount of heat in the rotating process, so that potential safety hazards appear. The present invention therefore proposes a new cooling system for a refiner.
Disclosure of Invention
The present invention aims to solve one of the technical problems in the related art to a certain extent. Therefore, the invention provides a cooling system of the refiner, which has the advantage of wide cooling range.
In order to achieve the above purpose, the invention adopts the following technical scheme:
a refiner cooling system comprising: a liquid guide tube having a liquid inlet and a liquid outlet, the liquid guide tube for conveying a cooling liquid; the stirring tank is provided with a stirring shaft and a cavity for containing slurry, the stirring tank is provided with a mounting cavity into which the stirring shaft extends, and the stirring tank is communicated with the liquid guide pipe; a cooling tank for cooling the stirring shaft, the cooling tank being in communication with the catheter; the liquid guide tube is formed with a first cooling channel for guiding the cooling liquid to flow from the liquid inlet to the stirring tank, a second cooling channel for guiding the cooling liquid to flow from the liquid inlet to the cooling tank, and a third cooling channel for guiding the cooling liquid to flow from the cooling tank to the mounting cavity.
In the invention, the liquid guide pipe is communicated with the stirring tank, the cooling tank and the mounting cavity of the stirring shaft arranged on the stirring tank, and the liquid guide pipe forms a first cooling channel for guiding cooling liquid to cool the stirring tank, a second cooling channel for guiding the cooling liquid to cool the cooling tank and a third cooling channel for guiding the cooling liquid to cool the stirring shaft in the mounting cavity. One end of the stirring shaft is connected with a blade for homogenizing, and the other end of the stirring shaft is connected with an output shaft of the motor. The stirring shaft is located in the installation cavity, the blades are located in the cavity for containing slurry, when the stirring shaft rotates under the action of the motor, the blades start the homogenization process, heat can be generated when the motor works and the stirring shaft rotates, and cooling liquid in the cooling tank enters the installation cavity through the third cooling channel to cool the stirring shaft. The cooling liquid flowing in the first cooling channel can cool the stirring tank and reduce the temperature of the slurry; the cooling liquid flowing in the second cooling passage can cool the cooling tank, so that the cooling liquid supplied from the cooling tank to the third cooling passage is kept at a low temperature.
Compared with the related art, the cooling system provided by the invention has three mutually matched cooling channels, the cooling range is wider, the stirring tank, the cooling tank and the stirring shaft can be cooled simultaneously, the cooling effect is more obvious, the refiner does not need to stop for heat dissipation, and the production efficiency and the safety are improved.
Optionally, the cooling liquid flowing along the third cooling channel is slurry. In the related art, water or glycerin or the like is generally adopted as cooling liquid, but as part of the stirring shaft always stretches into the cavity to drive the stirring blades, absolute separation between the installation cavity and the cavity is impossible to be kept, and the cooling liquid in the installation cavity still has the probability of being thrown into the cavity (namely, entering the slurry to be stirred) to pollute the slurry. The invention takes the slurry as the cooling liquid flowing along the third cooling channel, and avoids the cooling liquid flowing into the mounting cavity from polluting the slurry in the cavity.

And the cooling liquid contained outside the spiral pipe in the containing cavity is conveyed to the mounting cavity where the stirring shaft is positioned through the third cooling channel so as to cool the stirring shaft conveniently. Preferably, the cooling liquid in the accommodating chamber (except the spiral pipe) is the same slurry as the components in the stirring tank, and the slurry in the stirring tank is not polluted after the cooling liquid is conveyed to the mounting chamber.
