Polishing structure for old sand regeneration

Abstract

The invention provides a polishing structure for old sand regeneration. The polishing structure is high in regeneration quality and low in energy consumption and can be used for screening sand particles. The polishing structure comprises a fixed static polishing disk and a rotatable movable polishing disk, wherein the static polishing disk and the movable polishing disk are arranged in parallel; a sand storage slot I and a sand storage slot II are respectively formed in the opposite end faces of the static polishing disk and the movable polishing disk; a sand guide hole for communicating the outer side of the static polishing disk with the sand storage slot I is also formed in the static polishing disk; a screening clearance is also formed between the static polishing disk and the movable polishing disk.

Description

technical field [0001] The invention relates to used sand processing equipment in casting production, in particular to an old sand recycling machine, specifically a frosted structure for recycling old sand. Background technique [0002] Existing dry-process used sand reclamation machines mostly use vibration and crushing to process the used sand. In the shell, the sand particles collide, shear, and rub against each other to peel off the residual adhesive film wrapped on the surface of the old sand particles. Purpose, and adopt the form of winnowing to screen, although its structure is simple, but regeneration effect is poor, energy consumption is high. Contents of the invention [0003] In view of the above problems, the present invention provides a frosted structure for regenerating old sand, which has high regeneration quality, low energy consumption, and can screen sand grains. [0004] Its technical scheme is as follows, the frosting structure of old sand regeneration...
