The invention relates to a sand washing device. The sand washing device comprises a sand washing main body, a lifting structure and a back-flushing pipe; the sand washing main body is provided with a sand washing cavity with an upward opening, a screen mesh is arranged in the sand washing cavity, the screen mesh has flexibility, an inlet for inputting slurry is formed above the screen mesh, the screen mesh is used for separating the slurry, so that muddy water in the slurry flows downwards through meshes of the screen mesh, and gravels in the slurry are intercepted on the screen mesh; the lifting structure is used for driving the screen mesh to shake, so that mud on gravel intercepted on the screen mesh falls off; and the back-flushing pipe is arranged at the bottom of the sand washing cavity, the back-flushing pipe is used for spraying a back-flushing medium for back-flushing gravels on the screen mesh to the screen mesh, the back-flushing medium is sprayed out from the bottom of the sand washing cavity from bottom to top, so that water flow upwards flushes the rolling gravels, the separation efficiency of the gravels and mud is improved, and the cleaning efficiency of the gravels is high. On the basis, the sand washing device is simple in structure, low in energy consumption and high in cleaning efficiency.
Description
technical field [0001] The present disclosure relates to the technical field of sand washing for river and lake bottom mud, in particular to a sand washing device. Background technique [0002] The sediment in the bottom mud of rivers and lakes is relatively viscous. Usually, the separated gravel needs to be cleaned repeatedly after the sediment is separated. The gravel is used as a resource to generate economic value. [0003] However, in the prior art, mechanical sand washing is time-consuming, water-consuming, and energy-intensive, while manual sand washing has low work efficiency and cannot meet the cleanliness of the gravel, that is, it cannot meet the cleanliness standard for sand and gravel resource recycling. Contents of the invention [0004] In order to solve the above technical problems or at least partly solve the above technical problems, the present disclosure provides a sand washing device. [0005] The present disclosure provides a sand washing device, in...
