[0020] Please see Figures 1 to 3 A device for washing river sand includes a washing tank 1, a rotating cylinder 2 rotatably connected inside the washing tank 1, the lower end of the rotating cylinder 2 extending to the lower end of the interior of the washing tank 1, a plurality of evenly distributed stirring blades 3 fixedly connected to the outer wall of the rotating cylinder 2, a spiral conveying blade 4 rotatably connected inside the rotating cylinder 2, the lower end of the spiral conveying blade 4 extending to the lower part of the rotating cylinder 2, a filter screen 5 sleeved on the outer wall of the rotating cylinder 2 fixedly connected inside the washing tank 1, a plurality of evenly distributed discharge ports 6 penetrating through the upper end of the outer wall of the rotating cylinder 2 and located above the filter screen 5, and a scraper 7 fixedly connected to the outer wall of the rotating cylinder 2 located below the discharge ports 6 and abutting against the upper surface of the filter screen 5 and the inner wall of the washing tank 1.

[0021] A spiral tube 8 is fixedly connected to the upper part of the inside of the cleaning tank 1.

[0027] As a technical optimization of this utility model, a motor 15 is installed on the right side wall of the drive box 11, and the output end of the motor 15 is fixedly connected to the third bevel gear 14.

[0028] In this embodiment: Start motor 15, motor 15 drives the third bevel gear 14 to rotate.

[0029] As a technical optimization of this utility model, the outer wall of the cleaning tank 1 is connected to a first drain pipe 16 located below the filter screen 5.

[0030] In this embodiment, the first drain pipe 16 can drain excess cleaning water from the cleaning tank 1, so that the level of cleaning water in the cleaning tank 1 is always kept at the same height.

[0031] As a technical optimization of this utility model, the outer wall of the cleaning tank 1 is connected to the feed trough 17 located below the filter screen 5.

[0032] In this embodiment, the feed trough 17 facilitates the addition of river sand and cleaning water into the cleaning tank 1.

[0033] As a technical optimization of this utility model, the outer wall of the cleaning tank 1 is connected to a discharge pipe 18 located above the filter screen 5, and the lower end of the discharge pipe 18 is flush with the upper end surface of the filter screen 5.

[0038] After preparation, the river sand to be washed is added into the washing tank 1 through the feed chute 17. Then, the motor 15 is started, and the motor 15 drives the third bevel gear 14 to rotate. The third bevel gear 14, together with the first bevel gear 12, drives the rotating drum 2 to rotate clockwise. The third bevel gear 14, together with the second bevel gear 13, drives the spiral conveyor blade 4 to rotate counterclockwise. The rotating drum 2 drives multiple stirring blades 3 and scrapers 7 to rotate. The river sand is stirred by the multiple stirring blades 3, thereby washing the river sand quickly and efficiently. During the washing process, the river sand slowly sinks to the lower end of the washing tank 1. Then, the spiral conveyor blade 4 conveys the river sand that has settled to the lower end of the washing tank 1, so that the river sand is conveyed through the rotating drum 2 to the discharge port 6. Then, it is discharged onto the filter screen 5 through multiple discharge ports 6.

[0039] When the river sand on the filter screen 5 is scraped, the high-pressure water pipe delivers high-pressure water to the spiral tube 8, and then sprays it out through multiple evenly distributed high-pressure nozzles 9. The high-pressure water washes the river sand on the filter screen 5 again. During the washing process, the washing water flows through the filter screen 5 into the interior of the cleaning tank 1, causing the liquid level of the cleaning water in the cleaning tank 1 to rise. Then the cleaning water in the cleaning tank 1 is discharged through the first drain pipe 16, so that the liquid level of the cleaning water in the cleaning tank 1 is always kept at the same height, effectively cleaning the river sand and quickly cleaning the silt adhering to the surface of the river sand, thereby improving the cleaning effect.
