[0002] At the construction site, people transport the concrete from the concrete mixing plant to various areas through concrete transport trucks. After transportation, there is a certain amount of residual discharge inside both the concrete transport truck and the mixing equipment. Therefore, in order to prevent the residual concrete from solidifying in the equipment and keep the equipment clean, people need to use a large amount of water to wash the equipment. The water after cleaning contains a large amount of construction raw materials, including insoluble substances such as cement, sand, and stones. If it is discharged into the river without treatment, it will cause serious pollution. At the same time, a large amount of concrete materials are wasted, which is not conducive to environmental protection and also causes waste of resources.
[0003] An existing sand and stone separator, with the publication number CN 218357723 U, includes a bottom plate. The upper surface of the bottom plate is fixedly connected with a body shell. Inside the upper surface of the bottom plate and the body shell, there is a drum sieve. The drum sieve is connected to the bottom plate through a bracket. Above the drum sieve, there is a scraping stone plate, and both ends of the scraping stone plate are fixedly connected to the inner wall of the body shell. However, a large amount of dust is generated during the processing of this type of sand and stone separator, resulting in dust accumulation in the device, affecting the use of the device. At the same time, the mortar is prone to splashing, which has an impact on the surrounding area, reduces safety, and is not conducive to use.
