Description

Technical Field

[0001] The invention relates to the technical field of sand and gravel cleaning, in particular to a water circulation treatment device for a sand washing machine. Background Art

[0002] Sand washing machine is a kind of equipment for washing sand and gravel, and its purpose is to separate sand and gravel from soil. At present, there are types of sand washing machines for river sand and sand and gravel mined from mountains and land. However, no matter which type of sand and gravel is used, there is a problem in the cleaning. Flushing is often carried out by spraying to clean the sand and gravel. The range of flushing of a single cleaning nozzle is limited. The adhesion between the surface of sand and gravel and the soil is strong, so the water pressure of the cleaning nozzle needs to be large enough. Although the spraying range can be expanded and the sand and gravel can be sprayed and cleaned, it is still impossible to achieve high-efficiency cleaning. The main problem is that the sand and gravel are relatively hard and bounce off the water flow, so that the sand and gravel are not 100% in direct contact with the strong water flow. However, if the sand and gravel are completely placed in the water for comprehensive and dead-angle cleaning, when the sand and gravel are completely placed in the water, the flushing force of the water flow cannot be further enhanced, and the sticky soil and impurities attached to the surface of the sand and gravel cannot be washed away by the enhanced water flow, which will affect the cleaning effect of the sand and gravel in reality.

[0003] Moreover, in the prior art, a series of more motors and other components are used to clean the sand and gravel when cleaning the fruit, but a group of motors cannot be used to control the overall cleaning of the sand and gravel, which will increase the actual operating cost of the sand and gravel cleaning equipment, increase the cost of related energy consumption, and further increase the cost of related maintenance, which is not conducive to the promotion and use of the equipment.
