Resin sand processing system

Abstract

The invention discloses a resin sand processing system and belongs to the field of casting equipment. The resin sand processing system comprises a doffing and crushing integrated machine; an output port of the doffing and crushing integrated machine is communicated with a twisting and rubbing regenerative chamber; an output port of the twisting and rubbing regenerative chamber is communicated with an air bellow; a lower end outlet of the air bellow is communicated with a buffering hopper; an outlet of the buffering hopper is communicated with a sending tank through a valve; the sending valve is communicated with a discharging tank through a pipeline which is provided with a supercharger; at least one partition plate evenly provided with through holes is arranged in the air bellow; a suction fan is arranged on the side of the portion, located above the partition plate, of the air bellow; and a dust collecting tank for collecting adhesion agent dust is fixed to the other end of the suction fan. The resin sand processing system in the structural design solves the problems that a resin sand regeneration machine body in the prior art is large in size, doffing is completed in another mechanism, and accordingly the occupied area is large, so that the occupied area of the resin sand processing system is reduced, and consumed energy is also greatly reduced.

Description

technical field [0001] The invention relates to equipment in the foundry field, in particular to a processing system for resin sand. Background technique [0002] Worldwide, more than 70% of castings are produced by sand casting. Generally speaking, for every 1 ton of qualified castings produced, 1 to 1.3 tons of waste sand will be produced. Discarding a large amount of waste sand not only wastes resources, but also causes great harm to the environment. After the casting mold is cast, if the binder in most of the molding sand has not undergone irreversible changes, as long as the impurities are removed, the original performance of the molding sand can be restored after ash suction cooling and re-mixing. This treatment method becomes Reuse of old sand, generally only sand molds made of clay bonded can be reused. [0003] For sand molds and sand cores that are chemically hardened (such as sand molds and sand cores made of oil sand, water glass sand, and various resin sands),...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned problems, the present invention provides a processing system for resin sand to overcome the problem that the resin sand recycling machine in the prior art is bulky and the doffing is completed by other mechanisms, resulting in a large footprint, thereby Reduced footprint of the resin sand treatment system and greatly reduced energy consumption
