Fine sand screening device capable of automatically discharging coarse sand

Abstract

The present invention relates to a screening device, in particular to a fine sand screening device capable of automatically discharging coarse sand, comprising a sand feeding cylinder assembly, a rotating disk assembly, a sand screening assembly, a coarse sand collection assembly, a sand screening drive assembly and The installation frame assembly, the sand inlet barrel assembly includes the sand inlet barrel body, the sand falling pipe, the sand rotating anti-blocking device, the upper supporting plate, the fixing column and the lower supporting plate; the lower end of the sand inlet barrel body is welded and connected to the falling Sand pipe; the lower end of the sand rotating anti-blocking device is connected to the inside of the sand inlet barrel body in rotation, and the upper end of the sand rotating anti-blocking device is connected to the upper supporting plate in a rotating fit, and the lower end of the upper supporting plate is fixed by The column is connected to the lower supporting plate; the sand falling pipe is connected to the lower supporting plate through threads. The invention can effectively solve the problem that the sand screening device in the prior art cannot automatically discharge the remaining coarse sand after fine sand screening; the invention can automatically discharge the coarse sand without manual cleaning, and its sand screening efficiency is high, and Sand works better.

Description

technical field [0001] The invention relates to a screening device, in particular to a fine sand screening device which can automatically discharge coarse sand. Background technique [0002] Sand is an essential basic raw material in the field of construction. There are many impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades for different purposes. The required sand particle size grade different. Therefore, it is necessary to sieve the sand before using it. Sand screening device, also known as dry land sand screening ship, sand and gravel separator, is a sand and gravel separation equipment suitable for rivers, reservoirs, coal yards and buildings. The screening machine is divided into drum sand screening machine, washing drum sand screening machine, vibrating screen sand screening machine etc. The sand sieving machine imitates the working principle of artificially using the inclined screen to screen sand....

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a fine sand screening device that can automatically discharge coarse sand, which can effectively solve the problem that the sand screening device in the prior art cannot automatically discharge the remaining coarse sand after fine sand screening; The set rotating disc assembly and sand screening assembly can automatically discharge the coarse sand after sieving the fine sand when it is used in conjunction with the sand screening, without manual cleaning. The sand screening efficiency is high and the sand screening effect is good.
