AI Technical Summary
The existing overflow pipe cleaning mechanism is fixedly connected to the motor output end and cannot move, causing the scraper to wear and cannot fit with the inner wall of the overflow pipe, resulting in concentrate foam adhered to the inner wall of the overflow pipe, reducing the flow rate and easily causing overflow.
A flotation column overflow pipe cleaning mechanism is designed. The motor output end drives the component to rotate, and pushes the component to slide and move, and always fits with the inner wall of the overflow pipe. Combined with the design of the rotating block and dovetail block, it ensures that the scraper always contacts the inner wall of the overflow pipe during rotation and movement.
It effectively reduces the adhesion of concentrate foam to the inner wall of the overflow tube, improves the flow rate of concentrate foam in the overflow tube, and avoids the problem of overflowing around the overflow tube.

The flushing mechanism fixed on the inner wall of the flotation column flushes the overflowing concentrate foam. When the flotation column fails after working for a long time, the concentrate foam on the top of the flotation column gradually increases and cannot be discharged. As the concentrate foam increases, the concentrate foam is discharged from the overflow pipe into the stirring tank. There is no need to stop the machine for maintenance. The overflow pipe cleaning mechanism cleans the inner wall of the overflow pipe to prevent the concentrate foam from adhering to its inner wall.
[0003] The existing overflow pipe cleaning mechanism is mainly composed of a motor and a scraper rod.

The scraper rod is fixedly connected to the output end of the motor and cannot move but can only rotate. After long-term use, the scraper rod is worn and cannot fit with the inner wall of the overflow pipe to clean its inner wall, causing the concentrate foam to adhere to the inner wall of the overflow pipe, reducing the flow rate of the concentrate foam in the vertical pipe of the overflow pipe, and easily causing the concentrate foam at the top of the flotation column to overflow from the surrounding wall of the flotation column.
