Surface grinding device for precoated sand recovery

Abstract

The invention relates to the technical field of precoated sand surface grinding, and discloses a surface grinding device for precoated sand recovery. The surface grinding device comprises a base, wherein a sliding plate is slidably connected to the top of the base through a sliding block and a sliding groove; two transverse rods are symmetrically and fixedly connected to the right side face of thesliding plate, two first springs are symmetrically and fixedly connected to the left side face of the sliding plate, and the left ends of the two first springs are fixedly connected with the top of the base through connecting plates; and the top of the sliding plate is fixedly connected with a screening box, a screen is fixedly connected between the inner side walls of the screening box, the leftside face and the right side face of the screening box symmetrically communicate with two sets of first dust suction pipes, and each set of first dust suction pipes comprises two first dust suction pipe bodies. The surface grinding device for precoated sand recovery solves the problems that the effect of resin removing by grinding is poor and the grinding efficiency is low due to the fact that precoated sand is generally difficult to be evenly ground when an existing precoated sand grinding device is used for grinding machining.

Description

Technical field [0001] The invention relates to the technical field of surface grinding of coated sand, in particular to a surface grinding device for recycling of coated sand. Background technique [0002] Precision casting molds made of coated sand can be used for precision casting to improve the quality and accuracy of castings. Therefore, they are widely used in industrial manufacturing. However, when using coated sand to make precision casting molds, there will Qualified and become waste products, in order to save resources, it is necessary to recycle the scrap precision casting molds. [0003] After recycling, scrap coated sand molds will undergo crushing, dust removal, iron removal and other processes to become coated sand again. Since the outer surface of coated sand is wrapped with resin, it is necessary to grind the coated sand to remove the resin on its surface , So as to obtain pure natural sand core for reuse and production. [0004] During the grinding process of the ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a surface grinding device for recycling coated sand, which solves the common problem that it is difficult to uniformly grind the coated sand when the existing coated sand grinding device is grinding, thus The effect of grinding to remove resin is not good, and the grinding efficiency is relatively low
