A progressive rapid drying equipment for foundry sand based on iron pieces

Abstract

The invention provides an iron-based progressive rapid drying equipment for foundry sand, comprising a feeding structure; the feeding structure is installed at the rear end of the heating structure, and the discharging structure is arranged at the front end of the heating structure; the discharging structure A cooling structure is arranged at the top of the support plate; the feed structure includes a feed chute, a support column, and a discharge chute, the feed chute is directly installed at the top of the support plate, and four vertical supports are fixed on the support plate. The top of the four support columns is fixed with a mounting plate, the bottom of the front end of the feeding trough is a discharging trough, and the bottom of the feeding trough is provided with a slope that slides toward the discharging trough. In the state of agglomeration, it is necessary to disperse the foundry sand in the feeding chute. The feeding chute is directly installed in the installation chute, so that the feeding chute can slide. At the same time, when the deflection wheel at the bottom of the feeding chute rotates, It can drive the feeding trough to shake, so as to realize the effect of dispersing the blocks of foundry sand under the shaking of the feeding trough.

Description

technical field [0001] The invention belongs to the technical field of casting sand drying equipment, and more specifically relates to a progressive rapid drying equipment for casting sand based on iron pieces. Background technique [0002] Foundry sand, foundry sand, also known as pearl sand, fused ceramsite sand, bauxite ceramsite sand. Fused ceramsite sand is made of high-quality bauxite as raw material, and is made by ceramsite sand processes such as calcination, electric melting, granulation, and screening. Pearl sand is a substitute for quartz sand, which overcomes the shortcomings of quartz sand such as large expansion coefficient, low precision of castings and severe sand sticking, and improves the quality of castings. [0003] Application number: In the patent of CN201310281324.2, the present invention discloses a method and equipment for drying and cooling foundry waste sand. Entering the rotary dryer, the hot blast furnace passes the hot air to the rotary dryer ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a progressive rapid drying equipment for casting sand based on iron parts, to solve the problem that the existing casting sand drying equipment will cause certain wear and tear at the place where it is stirred and dried after a long time of use. Directly blowing it during the heat dissipation process of the body will cause sand mist, which will cause some inconvenience to the heat dissipation of the sand body
