step S2: the water pump 7 sends the impurity sewage in the sand tank of the sand washer to the water inlet pipe 66 of the separating device 6 through the water pipe 8, and then flows into the water storage barrel 62, the upper blocking plate 613 is opened outwards, the lower blocking plate 614 is closed to form a closed pipeline, the water level of the sewage gradually rises and overflows the flow stabilizing plate 69, the motor 67 is started, the motor 67 drives the stirring rod 68 to rotate, the stirring rod 68 rapidly rotates to form a vortex in the center of the water storage barrel 62, the speed of the vortex center is higher than that of the sewage on the barrel wall of the water storage barrel 62, some impurities and particles with larger mass are gathered to the center of the vortex and fall down through a round hole in the center of the flow stabilizing plate 69 for deposition, the impurity sewage at the lower part of the water storage barrel 62 is buffered and vibrated due to the blocking of the flow stabilizing plate 69, the fluidity of the sewage is reduced, the impurities and some particles can gradually fall down into the sand settling pipe, the vibrator 612 drives the sand settling pipe 610 to shake within a small range to enable impurities and particles in yellow sand to be tightly gathered, when impurity particles are accumulated on the upper blocking plate 613, an electric push rod is started, the electric push rod drives the upper blocking plate 613 to move inwards to close the pipeline, another electric push rod is started, the lower blocking plate 614 is opened outwards to enable the impurity particles to be separated from the sand settling pipe 610, then the lower blocking plate 614 is closed inwards, and the upper blocking plate 613 is opened outwards again;
step S3: the sewage in the sand washer continuously flows into the water storage barrel 62, the stirring rod 68 continuously rotates, impurities and particles continuously fall and deposit, the separated water level rises to the transition plate 64, the filtered and separated sewage flows into the water outlet barrel 63 on one side of the filter screen 616 through the transition plate 64, the sewage flows out of the water outlet barrel 63 on the other side of the filter screen 616 after being filtered and deposited by the filter screen 616, the sewage is conveyed to the water pipe 8 through the water pump 7 through the water outlet pipe 617, the sewage flows into the water injection head 4 and the water spray head 5 through the water pipe 8, the water is flushed into yellow sand in the wheel groove of the sand washer, and the yellow sand after being flushed falls onto the conveyor belt 33 of the sand outlet device 3 and is conveyed to a sand collecting position;
step S4: and continuously and circularly repeating the steps S2-S3, so that impurities and particles in the sewage can be separated, and meanwhile, the separated sewage can continuously and circularly wash the yellow sand in the sand washer.
It should be understood that the above is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow transformations made by the present specification and drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
