[0025] Working principle: Ore is placed in the screen cylinder (5), and the screen cylinder (5) is placed in the installation cylinder (1). Through a set of installation pipes (306) and by controlling the opening of a set of valves, the tank liquid is introduced into the installation tank (301). The tank liquid enters the installation cylinder (1). The air pump is connected through the air inlet pipe (7), and the air outlet plate (207) pumps gas into the installation cylinder (1) to float the ore in the screen cylinder (5). The motor (201) is started, which drives the rotating rod (202) to rotate. This drives the bevel gear (204) to mesh with the gear ring (206), which drives the connecting rod (203) to rotate, causing the rotating plate (205) to rotate. The rotating plate (205) agitates the tank liquid and agitates the gas in the tank liquid. The bubbles are dispersed to prevent them from becoming too dense, reducing the generation of foam on the surface of the tank liquid, making it easier to observe and control the amount of tank liquid. By controlling the start of the ultrasonic level gauge (303), the ultrasonic level gauge (303) measures the level of the tank liquid in the installation tank (301). The needle (305) punctures the foam on the surface of the tank liquid and cleans the foam to prevent it from affecting the accuracy of the measurement results of the ultrasonic level gauge (303), reducing manual operation and reducing labor burden. The tank liquid in the installation tank (301) is discharged through another set of installation pipes (306) and controlled by another set of weights, and the level of the tank liquid is controlled to improve the effect of the device.
