7. A coal washing water filtering and screening process for the coal washing water filtering and screening device of any one of claims 1 to 6, which is characterized by comprising the following steps:

the method comprises the following steps: the device is externally connected with a power supply, the water pump is started, and the water pump quickly cleans and pumps the sewage in the water tank into the top end of the main body through the water inlet pipe; and then, when coal washing wastewater enters the inside of the main body, a high-speed rotating flow field is not formed in the inside of the main body, at the moment, the first discharging pipe and the second discharging pipe are closed, sewage downwards enters the top surface of the partition plate and the inside of the fixed pipe, and untreated sewage flows into the inside of the water tank again through the circulating pipe and the circulating pipe on the side wall of the supporting pipe.

Step two: when a high-speed rotating flow field is formed inside the main body, and the pressure of the external vortex flow inside the main body on the fan blades reaches 0.1 MPa, water flow pushes the fan blades to rotate, the fan blades push the fixed pipe, the rotating shaft and the supporting rod to rotate, and the fixed pipe rotates at the bottom end of the supporting pipe; the support rod drives the ball to rotate, the ball rotates in the spiral chute, the ball performs circular motion to compress the joint and the second discharging pipe, the ball rotates along the chute to enable the joint, the first discharging pipe and the second discharging pipe to operate and elongate the second spring, the first discharging pipe enters the fixed funnel, the fixed funnel is sealed by the first discharging pipe, water and large particle impurities enter the first discharging pipe, the bottom end of the fixed pipe is sealed by the downward motion of the second discharging pipe, the treated sewage and small particle impurities are discharged from the top end of the main body through the second discharging pipe, and when the ball moves from the inside of the chute to enter the inside of the clamping groove, the ball rotates along the inclined annular clamping groove, the top end of the first discharging pipe slightly and continuously moves up and down in the fixed hopper, and the rotating shaft pushes the spiral blade to rotate in the first discharging pipe, so that large-particle materials can conveniently penetrate through the first discharging pipe, and the first discharging pipe is prevented from being blocked; when the fan blades on the side walls of the fixed pipe and the fixed pipe rotate, the fan blades rotate to generate upward thrust to enter the wastewater in the main body, one part of the wastewater upwards moves inwards along the lower surface of the top cover and downwards along the outer wall of the vortex overflow pipe due to the friction resistance of the wall of the main body, and the fan blades rotate to upwards push the part of the wastewater to upwards spirally rotate to enter an outer vortex and downwards move along with the outer vortex, so that the short-circuit flow in the main body is reduced.

Step three: work as the inside water intaking that stops of main part, this moment the inside high-speed rotatory flow field of main part destroys, and rivers do not promote the flabellum rotates, the ball is in the inside slow stall of draw-in groove, first spring with the second spring motion shrink drives connect the downstream, the second is arranged the material pipe upward movement, makes the ball is in the draw-in groove with reverse motion in the spout makes connect with first row of material pipe downstream opens fixed funnel makes first fixed ball will the bottom seal of first row of material pipe.
