[0001] The utility model patent relates to the technical field of water-washed sand processing and preparation, and specifically to a water-washed sand processing and preparation device. Background Art

[0002] Stone washing machine is also called sand washing machine (or sand washing machine). It is used for desludging and screening of large amounts of sand and gravel in construction sites, sand and gravel plants, prefabrication plants and hydropower sites. It can also be used for ore sorting. Stone washing machines can be roughly divided into spiral stone washing machines, drum stone washing machines, water wheel stone washing machines, vibration stone washing machines, bucket stone washing machines and cylinder stone washing machines. Stone washing machines are used to clean sand and gravel from sand excavation and mining. Water is mainly used for cleaning. Sand and gravel mined from the river bottom or rock formation still have relatively impurities. Water is needed to be used for washing to separate the soil and gravel from the sand and gravel to achieve the purpose of purification.

[0003] However, most of the current sand washing machines are prone to produce a large amount of sewage and silt during sand washing, and these silts are usually discharged into rivers. Such a large amount of discharge can easily lead to water pollution and blockage of water flow, polluting the environment. Therefore, a water-washed sand processing and preparation device is proposed. Utility Model Content
