Rapid sand screening device for building construction

Abstract

The invention discloses a rapid sand screening device for building construction. The rapid sand screening device comprises a bottom plate and a screening box fixed on the bottom plate, and a feeding hopper is vertically and fixedly installed at the top part of the screening box; a sieve plate is horizontally arranged in the screening box in a sliding mode; a driving gear is connected to a horizontal support through a motor in a driving mode, and a first semicircular gear is coaxially and fixedly installed on the front side of the driving gear; and the bottom part of the bottom plate is fixedlyprovided with an air heater and a draught fan connected with the air heater through a pipeline. According to the rapid sand screening device, spiral blades are driven to rotate through forward and reverse rotation of a forward and reverse rotation motor, the spiral blades rotate and dissipate sand, sand can move back and forth in the left-right direction at the same time, so that screening of thesand is promoted; the sieve plate moves back and forth in the left-right direction, so that left and right shaking of the sand is realized; meanwhile, upper convex blocks and lower convex blocks arecoordinated with each other, so that small vibration of the sieve plate is realized, and the sand is accelerated to pass through the sieve plate; and hot air sprayed into the screening box by an air injection disc plays a role in drying the sand, so that the sand is more dispersed, and therefore the screening effect is better.

Description

technical field [0001] The invention relates to the technical field of building construction machinery, in particular to a quick sand screening device for building construction. Background technique [0002] With the rapid development of our country's economy and the continuous progress of social science and technology, there are currently many construction sites in our country. The construction sites mainly promote the rapid development of our country's economy through the construction of houses and related factories. In construction sites, sand It is an indispensable technical raw material in the construction site. Sand is used on the construction site for building walls and other processes. There are various impurities in the sand, which need to be screened. Sand screening devices are often used in construction sites. It is convenient for people to use after the impurities in it are sun-dried. However, in the actual sand screening process, due to the moisture contained i...

AI Technical Summary

Problems solved by technology

However, in the actual sand screening process, due to the moisture contained in the sand, it is difficult to sieve the agglomerated sand, and the sand is easy to cause the blockage of the sieve mesh, and the sieving speed is stirred, and the sieving effect is not ideal.
