Foundry sand incremental fast-drying equipment based on iron piece

Abstract

The invention provided foundry sand incremental fast-drying equipment based on an iron piece. The equipment comprises a feeding structure. The feeding structure is mounted on the rear end of a heatingstructure, and a discharging structure is mounted on the front end of the heating structure. The top of the discharging structure is provided with a cooling structure. The feeding structure comprisesa feeding tank, supporting columns, and a discharging tank. The feeding tank is directly mounted on the top of a supporting plate. Four vertical supporting columns are fixed to the supporting plate.A mounting plate is fixed to the tops of the four supporting columns. The discharging tank is mounted at the bottom of the front end of the feeding tank. The bottom of the feeding tank is provided with an inclined plane sliding to the discharging tank. Foundry sand entering into the feeding tank is usually in a caking state, and needed to be broke up in the feeding tank. The feeding tank is directly mounted on a mounting sliding slot, so that the feeding tank can slide. Meanwhile, the feeding tank can be driven to shake when a direction-deviating wheel mounted at the bottom of the feeding tankrotates, so that the dispersing effect of the foundry sand block under the shaking of the feeding tank can be realized.

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
