During the rotation of the runner 10-1, part of the mud with larger particle sizes is decomposed into mud with smaller particle sizes along with the friction with the sand and the runner 10-1. Drain from the first through hole and the second through hole 0121 into the sand washing tank 01 to contact with water and dissolve in water to complete sand washing.

The second through hole 0121 is set on the sieve plate 012. Compared with the scheme of not opening a hole in the sieve plate 012, the mud with a larger particle size can leak down through the first through hole, and can also leak to the sieve through the second through hole 0121. On the net 06, it leaks into the sand washing tank 01 through the first through hole and mixes with water to make the mud decompose faster, so that the particle size of the mud entering the sand washing tank 01 is smaller and more soluble in water, so that the washing Sand is faster.

Specifically, the sieve plates 012 and the flat plates 013 are alternately arranged between two adjacent partition plates 011 , and in a preferred embodiment, the inclination angles of the sieve plates 012 and the flat plates 013 on the screen 06 are the same. In a further preferred embodiment, the distance between the sieve plate 012 and two adjacent sieve plates 013 is equal, and the distance between the plate 013 and two adjacent sieve plates 012 is equal.

Because the silt mixture also contains sand with a smaller particle size, the smaller sand with a particle size can also leak down through the sieve plate 012 and the screen cloth 06, so that the sand that is pushed forward when the runner 10-1 rotates is less, so Flat plate 013 is set, no hole is opened on the flat plate 013, the sand with less particle size is received by the flat plate 013 after being leaked through the sieve plate 012, and then pushed forward along with the rotation of the runner 10-1 to increase the discharge speed of the sand.

Such setting maximizes the advantages of multiple baffles. Compared with the scheme in which one baffle or multiple baffles are arranged flush with each other, the discharge is continuous and stable. The required driving force is always relatively stable, and the power consumption of the motor 03 is also saved.

The structure of taking away the muddy water in the upper layer of the sand washing tank is omitted in the figure, and the sand after washing is unloaded from the discharge end 1122 to complete the process of washing sand.

Since modern production lines require high sand washing efficiency and large sand output, in actual production, although a single sand washing machine can achieve a good sand washing effect, the mud content in the sand after washing can be very low. , but the amount of sand produced by a single sand washing machine is small, and the form of multiple sand washing machines connected in series is adopted. The technical requirements of each sand washing machine are slightly lower than those of a single sand washing machine in order to achieve a large amount of sand.
