Resin gel waste core sand reproduction line

Abstract

The invention relates to a resin gel waste core sand reproduction line which comprises a pre-coated sand reproduction device and a resin gel core sand processing device. The pre-coated reproduction device comprises a pretreatment system, a hot-method reproduction method, a dust removal system and an electric control system. The electric control system is connected with the pretreatment system, the hot-method reproduction device and the dust removal system. The pretreatment system comprises a crushing screening machine and a magnetic separator. The hot-method reproduction device comprises a feeding machine, a waste sand calcinator, a cooling bed and a reproductive pre-coated sand storage bin, which are connected sequentially. The dust removal system is connected with the crushing screening machine, the waste sand calcinator and the cooling bed through a pipeline. The resin gel core sand processing device comprises a feeding device, a resin gel core sand hot-method reproduction device, a resin gel core sand delivery device and a screening device, the feeding device is connected with the reproductive pre-coated sand storage bin, and the resin gel core sand hot-method production device comprises a pre-coated sand calcinator which is provided with a pre-coated sand feeding hopper and a resign feeding hopper. Reproduction of waste sand is achieved, waste is turned into treasure, cost is economized and environmental friendliness is achieved.

Description

Technical field [0001] The invention relates to a production and processing equipment for foundry sand, to be precise, a resin core sand recycling production line formed by a combination of processing equipment. Background technique [0002] Foundry sand is a kind of granular refractory material used to prepare molding sand and core sand in foundry production. The common foundry sand is coated sand, which is also called resin sand; however, in the actual production process, the workpiece or product made of this sand still has insufficient performance, such as tensile strength; the inventors have improved Invented a resin core sand to improve the performance of the produced castings; the corresponding inventor designed the processing and production equipment of this resin core sand; the resin core sand cannot be directly recycled after use, and needs to be reprocessed. use. In the prior art, there is no regeneration equipment for resin core sand, and the resin core sand becomes ...

AI Technical Summary

Problems solved by technology

Foundry sand is commonly coated sand, also known as resin sand; however, in the actual production process of this sand, the workpiece or product made still has insufficient performance, such as tensile strength; the inventors aimed at this situation and improved Invented a resin core sand to improve the performance of the produced castings; correspondingly, the inventor designed the processing and production equipment for this resin core sand; the resin core sand cannot be recycled directly after use, and it needs to be reprocessed before it can be recycled. use

In the prior art, there is no recycling equipment for resin coagulated sand, and resin coagulated sand is turned into garbage after use, which not only causes waste and pollutes the environment, but also increases the processing cost of resin coagulated sand
