With the increasing demand for ready-made concrete in the construction market, the production of ready-made concrete has become the main building material industry in cities. Compared with the concrete prepared on site, ready-made concrete is of uniform quality, easy to use and does not require builders to purchase additional mixing equipment. Concrete transport vehicles load concrete at the discharge port of the concrete mixing building and transport the concrete to various construction sites. The mixing equipment and concrete transport vehicles have certain discharge residues. In order to prevent the residual concrete from solidifying in the equipment and keep the equipment clean, A large amount of water needs to be used for washing. The water used for washing contains a large amount of construction materials, including insoluble matter such as cement and sand. If it is discharged to the river without treatment, it will cause serious pollution and waste a lot of tap water. and concrete materials; at the same time, if the remaining concrete materials are discarded directly after use, it will not only waste resources, but also be harmful to environmental protection.

In view of the above problems, at present, the Chinese patent with the publication number CN103406195A discloses a kind of sand and gravel separation equipment.
