A recycling treatment system and treatment process of coated sand precision casting waste sand

Abstract

The invention relates to a waste sand reuse treatment system and treatment process for coated sand precision casting, including a workbench, a cutting mechanism, a crushing mechanism, an electric conveyor belt, a heating evaporation mechanism and a rinsing mechanism. The present invention can solve the following problems in the recycling process of foundry waste sand: a. During the recycling process of traditional foundry waste sand, the coated sand is directly heated and melted by means of heating, etc., and the auxiliary agent in the coated sand is evaporated, but because it has not been pulverized, the additives inside the coated sand still cannot be completely cleaned, which affects the treatment effect of the coated sand, which in turn affects the recycling and reuse of the coated sand. b During the recycling process of traditional foundry waste sand, Even though the efficiency of heating and evaporating treatment is very high, there are still some additives attached to the surface of the sand, and the additives tightly bond the sand. If the additives are not completely cleaned up, the recycling and reuse of the coated sand will be affected.

Description

technical field [0001] The invention relates to the field of reuse and treatment of foundry waste sand, in particular to a treatment system and process for the reuse and treatment of coated sand precision casting waste sand. Background technique [0002] With the continuous improvement of casting technology, precision casting sand such as coated sand gradually began to appear in people's daily production and processing. In the construction process of the body, it plays a vital role. After the sand is artificially added with additives, the coated sand is constructed into the desired shape through molding and other processes. When the casting process is over, the coated sand is usually Recycling. [0003] At present, the following problems exist in the recycling process of foundry waste sand: a. During the recycling process of traditional foundry waste sand, the coated sand is directly heated and melted by means of heating to evaporate the additives in the coated sand. , but...

Problems solved by technology

[0003] At present, the following problems exist in the recycling process of foundry waste sand: a. During the recycling process of traditional foundry waste sand, the coated sand is directly heated and melted by means of heating to evaporate the additives in the coated sand. , but because it has not been pulverized, the additives inside the coated sand still cannot be completely cleaned, which affects the treatment effect of the coated sand, and then affects the recycling and reuse of the coated sand. The efficiency of evaporation treatment is very high, but there are still some additives attached to the surface of the sand, and the additives tightly bond the sand. If the additives are not completely cleaned up, the recycling and reuse of coated sand will be affected.
