A crushing and iron removal device for the recycling of coated sand shells

Abstract

The invention relates to the technical field of film-coated sand shell-type crushing and iron removal, and discloses a film-coated sand shell-type crushing and iron removal device for recycling. The inner top wall of the box is fixedly connected with a fixed plate, the bottom of the fixed plate is fixedly connected with a partition, and the right side of the working box is symmetrically fixedly connected with two first motors through a supporting plate, and the two first The output ends of the motors are fixedly connected with rotating shafts, the left ends of the two rotating shafts pass through the right side of the working box and are connected with the right side of the fixed plate in rotation, and the outer circular surfaces of the two rotating shafts are fixedly connected with broken roll. The invention solves the problem that the existing film-coated sand shell-type crushing and iron removal device is difficult to fully remove iron from the film-coated sand shell-type particles, resulting in low iron removal quality and low iron removal effect. Poor question.

Description

technical field [0001] The invention relates to the technical field of crushing and iron removal of film-coated sand shells, in particular to a crushing and iron removal device for recycling film-covered sand shells. Background technique [0002] Covered sand shell mold casting has the advantages of good surface quality and high dimensional accuracy of the cast parts, and the coated sand shell mold casting has the characteristics of less equipment investment, small footprint, high production efficiency and low noise during production, so It is widely used in the field of precision casting. [0003] After the coated sand shell is used in production for a long time, its dimensional accuracy will gradually decrease until it cannot be used. In order to save resources and reduce costs, the coated sand shell will be recycled and reused. The coated sand needs to be recycled during the recycling process. The shell is crushed and iron is removed, so as to ensure that the subsequent ...
