[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] In the attached diagram, all identical reference numerals refer to the same components.

[0022] like Figure 1-3As shown, this utility model provides a sand washing machine for sand and gravel processing. The fixed base 3 serves as the supporting base for the entire equipment and is horizontally installed on the ground or other load-bearing structure. One end of the fixed base 3 has a discharge port 404 for discharging the washed sand and gravel. A sand washing impeller 2 is installed above the fixed base 3, and its rotating shaft is directly connected to the output end of a drive motor 201 on one side of the fixed base 3 via a coupling, and is driven to rotate by the motor. The blades of the sand washing impeller 2 are arranged in an arc or spiral shape, and when rotating, they can mix and wash the sand and gravel with water, removing surface impurities.

[0023] Furthermore, a vibrating screen 4 is installed on the bottom side of the sand washing impeller 2. The vibrating screen 4 is divided into two layers from top to bottom: the top layer, a coarse filter screen 401, is used to intercept large particles of impurities in the sand and gravel. A slag storage space 402 is formed above the coarse filter screen 401, and the accumulated impurities are cleaned periodically. The bottom layer, a fine filter screen 403, has a higher mesh size than the coarse filter screen 401 and is used to separate qualified sand and gravel from fine slurry. The area between the coarse filter screen 401 and the fine filter screen 403 is the sand discharge space. After screening, the sand and gravel move towards the discharge end through vibration. Below the fine filter screen 403 is the water filtration space, and multiple water outlets 405 are opened at the bottom of it to discharge the wastewater generated during washing to an external sedimentation tank or circulation system.

[0024] Furthermore, vibrating motors 407 are symmetrically installed at both ends of the vibrating screen 4 to accelerate the screening and dewatering of sand and gravel through high-frequency vibration. The discharge end of the fine filter screen 403 is connected to an inclined discharge slope 406, which extends into the discharge port 404 of the fixed base 3, using gravity to transport the sand and gravel to the external collection area.

[0025] Workflow: The sand and gravel to be washed enter the sand washing impeller 2 area, where impurities are removed under the combined action of blade rotation and water flow; the sand and gravel mixture falls to the vibrating screen 4, where the coarse filter screen 401 intercepts large particles of impurities and temporarily stores them in the slag storage space 402; the remaining sand and gravel are screened a second time by the fine filter screen 403, and qualified sand and gravel are discharged through the sand discharge space and the discharge slope 406, while mud and sewage pass through the fine filter screen 403 and enter the water filtration space, and are discharged from the water outlet 405; the vibrating motor 407 works continuously to prevent the screen from clogging and to improve the dewatering efficiency.

[0026] This utility model relates to a sand washing machine for sand and gravel processing. It utilizes a layered coarse filter 401 and fine filter 403 in conjunction with a vibrating screen 4 to effectively separate large particles of impurities from qualified sand and gravel, reducing the risk of screen clogging. An inclined discharge slope 406, working in conjunction with a vibrating motor 407, improves sand and gravel conveying efficiency and reduces residual moisture. The filtration space is connected to an external circulation system, significantly reducing water consumption. The modular design of the vibrating screen 4 and its quick-release structure facilitates maintenance and reduces downtime. The overall structure improves sand and gravel cleanliness and yield while also prioritizing energy conservation, environmental protection, and ease of operation.
