A device for recycling sand and soil after lost foam casting

Abstract

The invention relates to a recycling device for sand and soil after lost foam casting. device, and the two crushing devices are symmetrically arranged left and right, the middle part of the frame is equipped with a reciprocating screening device, the inner lower end of the frame is equipped with a conveying line, and the front outer wall of the frame is equipped with a driving device. The invention can solve the problem that the sand is in a high-temperature state during the casting process, and some large particles of metal impurities will be produced, and the sand with a higher temperature may also be bonded. The traditional sieve plate treatment is difficult to solve, and the natural cooling time Long, the temperature inside the sand layer is difficult to cool down, and the sand cannot be used for the next batch of lost foam casting, which increases the production investment cost to a certain extent.

Description

technical field [0001] The invention relates to the technical field of casting molds, in particular to a device for recycling sand and soil after lost foam casting. Background technique [0002] Lost foam casting, also known as solid casting, is a new casting method after ground molding. It has the characteristics of accurate casting size and shape, good repeatability, and precision casting. The casting can be taken out after the soil is poured out, but the sand cannot be used directly without treatment. [0003] In the traditional technology, it needs to be recycled after natural cooling and sieve plate treatment. However, this traditional method often has some defects: [0004] 1. The sand is in a state of high temperature during the casting process, and some large particles of metal impurities will be produced, and the sand with a higher temperature may also be bonded, which is difficult to solve by traditional sieve plate treatment; [0005] 2. The natural cooling time...

AI Technical Summary

Problems solved by technology

[0004] 1. The sand is in a state of high temperature during the casting process, and some large particles of metal impurities will be produced, and the sand with a higher temperature may also be bonded, which is difficult to solve by traditional sieve plate treatment;

[0005] 2. The natural cooling time is long, and the temperature inside the sand layer is difficult to cool down. The sand cannot be used for the next batch of lost foam casting, which increases the production investment cost to a certain extent.
