Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing devices, and in particular to a mixing device for coating materials. Background Technology
[0002] Currently, Chinese utility model patent CN222777983U discloses a coating mixing and stirring device. Although this mixing device is equipped with a stirring component, which can mix materials and prevent solidification through agitation, other problems still exist during use, such as poor mixing effect. The flow of liquid inside the device relies entirely on the stirring of the stirrer, which is difficult to radiate to all layers when placed in the liquid, easily resulting in uneven mixing of liquid at different layers. Moreover, it does not have an active bubble elimination function. Air enters the tank with the material and generates a large number of bubbles during stirring. After the bubbles form, they will form cavitation in the liquid. Therefore, the mixed materials often need to stand for a period of time to allow them to dissipate naturally. In order to solve the above-mentioned problems, we propose a coating material mixing device. Utility Model Content

[0016] The present invention is further configured such that a moisture-proof pad is bolted to the bottom of the fixed frame, and the moisture-proof pad is made of rubber.
[0017] By adopting the above technical solution and setting up a moisture-proof pad, the moisture-proof effect of the bottom of the fixing frame can be improved, reducing the impact of ground dampness.

The circulation pump, upon starting, draws in the sedimented coating from the bottom of the mixing tank through a suction valve. The coating is then transported upwards through a discharge pipe to a higher position, and finally returned to the mixing tank from there. This improves the mixing effect of the device, accelerates the fusion of liquids at different levels, and is highly practical.
[0022] 2. This utility model simultaneously activates the resistance wire and the vacuum pump. After the resistance wire is activated, it generates heat, which is transferred to the mixing tank to raise its temperature. After the mixing tank is heated, it will heat the liquid inside to initially defoam. After the vacuum pump is activated, it will suck out the gas inside the mixing tank to create a pressure difference, which will cause the bubbles to rise to the surface of the liquid and disappear faster. It has an active defoaming function, is simple and convenient to operate, improves the efficiency of eliminating internal bubbles, and ensures the quality of the mixed liquid.

When the stirring impeller 33 rotates, it drives the liquid to stir. After the circulation pump 4 starts, it sucks in the sedimented coating at the bottom of the mixing tank 1 through the suction pipe valve 5. After the coating is sucked in, it is transported upward to a higher position through the discharge pipe 6 and finally put back into the mixing tank 1 from the higher position. This can improve the mixing effect of the device, accelerate the fusion of liquids at various levels, and has high practicality.

[0034] Brief description of the usage process: First, pour the paint into the mixing tank 1. After pouring the paint, start the motor 31 and the circulation pump 4 at the same time.
