AI Technical Summary

Technical Problem

The existing double-spiral sand washing machine cannot directly screen sand and gravel, which causes sand and gravel to be transferred to the screening machine through a conveyor for screening, which is inefficient and time-consuming.

Method used

A new double helix sand washing machine was designed, including a base plate, a groove body, a spiral blade, a drive motor, a screening groove, a screen, an elastic support structure and a vibration motor. Through the rotation of the spiral blade and the vibration of the vibration motor, sand and gravel can be transported and screened.

Benefits of technology

The direct screening of sand and gravel is realized, coarse sand and fine sand are separated, which improves the sand washing efficiency, reduces the time for sand and gravel transportation, and enhances the versatility of the sand washing machine.

Abstract

The novel double-screw sand washer comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a plurality of first supporting rods, the top ends of the first supporting rods are jointly and fixedly connected with a groove body, the interior of the groove body is rotationally connected with two rotating shafts, and the surfaces of the two rotating shafts are fixedly connected with screw blades. An overflow tank is fixed to one side of the top end of the tank body, a water outlet is formed in the bottom of the overflow tank, and a sand outlet is formed in the side, away from the overflow tank, of the bottom of the tank body. According to the sand washing machine, the bottom plate, the groove body, the spiral blade, the driving motor, the screening groove, the screen mesh, the elastic supporting structure, the vibration motor and the material guide groove are arranged, the spiral blade is driven by the driving motor to rotate so that sand can be conveyed, water with soil ash flows out of the overflow groove, the sand can fall onto the surface of the screen mesh after being discharged, and therefore washed sand can be screened; coarse sand and fine sand can be separated out, and multifunctionality of the sand washer is achieved.
