Screening device for glass sand

Abstract

The invention discloses a screening device for glass sand. The screening device comprises a bottom plate; the top of the bottom plate is fixedly connected with a first fixing plate and a second fixingplate in sequence from the obverse side to the reverse side; a feeding hopper is fixedly connected between the first fixing plate and the second fixing plate, and two driving shafts located below thefeeding hopper are movably connected between the first fixing plate and the second fixing plate; and two driven shafts located below the driving shafts are movably connected between the first fixingplate and the second fixing plate, and the distance between the two driven shafts is smaller than that of the two driving shafts. According to the screening device for the glass sand, the feeding hopper, the driving shafts, the driven shafts, a conveyor belt and a motor are arranged so that a switch can drive the motor to work, and the glass sand enters the conveyor belt from the feeding hopper; and the driving shafts rotate, and the driven shafts rotate, so that the conveyor belt rotates, the glass sand moves downwards and cannot be stacked together during screening, and screening is facilitated.

Description

technical field [0001] The invention relates to the technical field of glass sand production and processing, in particular to a screening device for glass sand. Background technique [0002] Glass sand is divided into colored glass sand and transparent glass sand. Transparent glass sand looks like white sugar, and glass sand is used for glass surface decoration, such as glass cups, vases, lampshades, etc. The glass sand is fused with the glass workpiece to form a concave and convex three-dimensional surface. Silica sand is mainly used to make glass products. Simply put, it is silicon-containing sand, and ordinary sand contains silicon. Generally, sand with high silicon content is a good raw material for glass making. Dyed glass sand can also be used in decorative or artistic fields. High-purity quartz sand can also be used to make glass sand. Glass sand needs to be screened during production and processing. [0003] However, the current glass sand screening device usua...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a glass sand screening device, which solves the problem that the current glass sand screening device usually only screens particles, and the iron filings mixed inside are not easy to be screened out, and are processed with glass sand to produce The qualification rate of the products produced will be greatly reduced, and it will also make the product less beautiful.
