Casting sand recycling treatment system

Abstract

The invention relates to a casting sand recycling treatment system. The casting sand recycling treatment system comprises a first conveying belt, a first elevator, a second conveying belt, a second elevator, a vibration screening machine and a screening device, wherein the screening device comprises a machine body, a magnet and rotating cylinders, the rotating cylinders are obliquely arranged, the number of the rotating cylinders is two, the side walls of the two rotating cylinders are attached to the tops of the rotating cylinders to form a screening groove, the rotating cylinders are coaxially provided with installing cavities, the shape of the magnet matches with the shape of the wall of the screening groove, the magnet is attached to the inner wall, close to the screening groove, of the installing cavity, the two rotating cylinders are driven by a driving mechanism arranged on the machine body to rotate, and the rotating directions of the two rotating cylinders are opposite. The screening device is arranged, so that casting sand and steel fragments are separated from each other, the quality of the recycled casting sand is better, a spiral pushing rod is arranged, the casting sand is stirred in the screening groove, the steel fragments in screened materials can make full contact with the outer wall of the rotary cylinders conveniently, the screening rate of the steel fragments is increased, and by arranging a shifting piece and an elastic piece, the casting sand is not prone to being brought out by the steel fragments.

Description

technical field [0001] The application relates to the field of metal parts, in particular to a casting sand recycling and processing system. Background technique [0002] Casting is a kind of metal thermal processing technology mastered by human beings earlier, with a history of about 6,000 years. Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. [0003] Sand mold casting is a kind of casting method. It needs to put the finished part model or wooden model in the cavity of the sand mold, and then fill the sand around the pattern. After taking out the pattern from the box, the sand forms a mold, and then pours the molten metal into the cavity of the sand mold for molding. Since the sand mold needs to be destroyed to take out the workpiece when taking out the molded workpiece, after the sand mold is destroyed, the casting sand needs to be recovered....

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, when the sand mold is recycled, some steel fragments produced by pouring will be mixed in. These steel fragments are cast into sand molds together with the casting sand, which will affect the quality of the sand mold.
