[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas washing water, equipment and site flushing water and other wastewater discharged in chemical production. If these wastewaters are discharged without treatment, they will cause different properties and degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production. Therefore, chemical wastewater needs to be treated through waste liquid purification equipment.

It has the following shortcomings: since the stirring rod is fixedly connected to the stirring shaft, even if the rubber cleaning pad is unwound, the contact area with the circumferential surface of the stirring rod is limited. For example, a rubber cleaning pad in an unwound state mounted between the two stirring rods can only clean the bottom of the upper stirring rod and the top of the lower stirring rod, and the rubber cleaning pad cannot touch the side surfaces of the stirring rods. In addition, the cleaning range of the two stirring rods located at the top and bottom is further limited, thereby affecting the cleaning effect of the circumferential surface of the stirring rod.
