A spiral sand washing machine with self-setting micro-washing function

Abstract

The invention discloses a high-efficiency spiral sand washing machine with the function of self-setting micro-washing, which belongs to the technical field of sand washing, and can realize the method of configuring a micro-washing cylinder at the discharge port, and the sand after preliminary washing enters into the micro-washing machine. In the barrel, the self-shaping laminating layer is forced to approach and wrap the sand and gravel surface through the effect of magnetic repulsion, which can closely contact the sand and gravel surface including grooves and dead corner areas. The hot air flow is passed into the laminated layer, and the micro-cleaning impact ball embedded in the self-shaping laminated layer forms a high-frequency vibration under the action of the airflow, and cooperates with the airflow to continuously slightly impact the surface of the sand and gravel, forcing stubborn impurities and the surface of the sand and gravel For detachment and peeling, the micro-washing impact ball will also drive the spoon-shaped elution sweep to rub repeatedly on the surface of the sand and gravel while vibrating, and can penetrate into tiny grooves or dead ends to accelerate the detachment effect and improve the elution effect of impurities on the sand and gravel surface .

Description

technical field [0001] The invention relates to the technical field of sand washing, and more specifically relates to a spiral sand washing machine with self-setting micro-washing function. Background technique [0002] Sand washing machine is a washing equipment for artificial sand (including natural sand). Sand washing machine is widely used in sand and gravel fields, mines, building materials, transportation, chemical industry, water conservancy and hydropower, concrete mixing stations and other industries to wash materials. It can remove impurities covering the surface of sand and gravel, and destroy the water vapor covering sand layer to facilitate dehydration and play a role in efficient sand washing and cleaning. Sand washing machine, also called stone washing machine, is mainly used to remove impurities (such as dust) from sand products. Because it uses water washing more often, it is called sand washing machine. Among them, because it is generally machine-made san...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing sand washing machine washes sand with a larger particle size, due to the larger surface area of ​​the sand, the impurities attached to it are also more and more stubborn, especially in some tiny grooves or dead corners. Whether it is stirring or washing, it is difficult to effectively remove some impurities, resulting in poor washing effect of sand and gravel, often requiring secondary treatment in the later stage, which seriously reduces the washing effect and processing efficiency of sand and gravel
