A kind of casting waste sand solid waste recycling processing equipment and processing technology

Abstract

The invention provides a casting waste sand solid waste recycling processing equipment and processing technology, comprising a grinding box, a grinding mechanism, a screening box, a screening mechanism, a sand collection frame and a support frame. The present invention can solve the following problems in the process of recycling solid waste in the casting process: a. Currently, some existing processing equipment for recycling waste sand in foundry mainly uses a crushing device to crush the waste sand to obtain reusable waste sand. core sand, but the current equipment does not have a good grinding and crushing effect on waste sand, cannot efficiently grind and recycle, the efficiency is low, and the function of the equipment is single; b. At present, some existing processing equipment for foundry waste sand recycling mainly The core sand is obtained by sieving and filtering. This kind of equipment can only be used for waste sand without clay sintered film on the surface, and it cannot be screened and recovered for agglomerated waste sand.

Description

technical field [0001] The invention relates to the technical field of solid waste recycling and processing, in particular to a recycling processing equipment and processing technology of foundry waste sand solid waste. Background technique [0002] Wet sand casting is made of casting sand and core sand as molding materials. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. In order to improve the surface quality of castings, brush a Layer coating, because green sand has many advantages such as low cost, high efficiency, and no pollution, green sand is the main molding process of sand casting. In the production of green sand casting, it is inevitable to generate a large amount of waste sand, mainly wet sand. After the molding sand is poured, the clay is sintered at high temperature and wrapped on the surface of the sand grains to form a solid ceramic layer, so that the waste sand cannot be used directly. [0003] At present, the following prob...

Problems solved by technology

[0002] Green sand casting uses sand and core sand as molding materials to make molds. Among them, steel, iron and most non-ferrous alloy castings can be obtained by sand casting. In order to improve the surface quality of castings, it is often brushed on the sand mold and core surface Because green sand has many advantages such as low cost, high efficiency, and no pollution, green sand is the main molding process of sand casting. In the production of green sand casting, it is inevitable to produce a large amount of waste sand, mainly wet After the molding sand is poured, the clay is sintered at high temperature and wrapped on the surface of the sand to form a firm ceramic layer, so that the waste sand cannot be used directly

[0003] At present, the following problems exist in the process of recycling solid waste in the foundry process: a. Some of the existing processing equipment for recycling foundry waste sand mainly uses a crushing device to crush the waste sand to obtain reusable cores sand, but the current equipment does not have a good grinding and crushing effect on waste sand, cannot efficiently grind and recycle, the efficiency is low, and the function of the equipment is single; Sieving and filtering to obtain core sand. This kind of equipment can only be used for waste sand without clay sintered film on the surface, and it cannot be screened and recycled for agglomerated waste sand, which makes the recycling efficiency of foundry waste sand not high.
