The motor rotates slowly and evenly to drive the dispersion shaft 903 to rotate, and then drives the dispersion blades 904 to rotate. The dispersion blades 904 rotate slowly and evenly, and the raw materials fall from the gaps between the blades, so that the raw materials falling into the sand washer main body 1 fall evenly and are dispersed evenly, avoiding eccentric loading and the raw materials being piled up and not stirred, avoiding damage to the wheel bucket and the machine body, improving the sand washing effect. The sand-containing wastewater after washing the sand and gravel inside the sand washer main body 1 is discharged from the water outlet 2 and enters the circulating water tank 3, and flows onto the filtering wheel 304. The filtered fine sand particles are brought into the sand accumulation box 306 by the rotation of the filtering wheel 304 and fall and accumulate, which is convenient for collection and will not block the filter screen. The water after filtration enters the static box 307 for static settlement. The water level rises slowly, and the static settled water slowly enters the water outlet pipe 302 and the water level also rises accordingly. After the water level reaches the highest position of the water outlet pipe 302, the circulating water starts to be sucked into the collection tank 4 until the water level is lower than the position of the water outlet pipe 302 in the static box 307. Before the water level is lower than the highest position of the water outlet pipe 302, it continues to be statically settled. The structure is simple, and the filtering quality of the circulating water is improved.
