To meet the demands of environmental protection and green development, research into treatment technologies for coal slime water is becoming increasingly necessary. Slurry water separation equipment is a key component of coal slime water treatment.

[0003] The existing invention patent with patent number 202410324781.3 provides a coal slurry water separation device for mines, including a separation box, a stirring assembly, a dosing assembly, a static assembly and a separation assembly. The stirring assembly includes a stirring air duct and a stirring fan. One end of the stirring air duct is tangentially connected to the separation box, and the other end of the stirring air duct is connected to the stirring fan; the static assembly includes a closing plate and a control part. The closing plate is hingedly arranged inside the stirring air duct. The closing plate is provided with a static state and an air intake state corresponding to different opening and closing angles; the separation assembly includes a water separation part and a sedimentation separation part. In actual application, the coal slurry water and the dosing water in the separation box are fully stirred and then left to stand. During this process, the separation device cannot continue to work.
