Casting resin sand regeneration production line

Abstract

The invention discloses a casting resin sand regeneration production line. The production line comprises a vibration shakeout machine. A material outlet is arranged under the vibration shakeout machine. A vibration conveyor is arranged in the material outlet. The vibration conveyor delivers the materials to a bucket elevator (A). The bucket elevator (A) transports the materials to a sand bin (A). The sand bin (A) delivers the materials into a grinding machine to grind the materials. Then the materials are transported to a sand bin (B) through a bucket elevator (B). The materials in the sand bin (B) are delivered to a boiling cooling bed so as to cool the materials. After cooling, the materials are delivered to a sand bin (C) through a bucket elevator (C). The materials in the sand bin (C) are transported to a sand bin (D) by a force regenerator. The material outlet of the sand bin (D) is provided with a sand temperature regulator. After the temperature is adjusted by the sand temperature regulator, and the materials are delivered to a sand bin (E) through a bucket elevator (D) and then transported to a sand mixing machine by a pressure feeding system so as to reclaim the materials. The provided casting resin sand regeneration production line can improve the recovery rate of resin sand, moreover, the recovering effect is good, the cost is low, and no pollution is generated.

Description

Technical field [0001] The invention relates to the field of recycling used foundry sand, and more specifically, it relates to a resin sand regeneration production line for foundry. Background technique [0002] Sand casting is a casting method for producing castings in sand. Because the molding materials used in sand casting are cheap and easy to obtain, and the molds are easy to manufacture, they are suitable for single-piece production, batch production and mass production of castings. In order to make the sand mold and core have a certain strength, it is usually necessary to Synthetic resin is added to form resin sand. [0003] With the continuous improvement of the quality requirements of mechanical products, the resin sand molding process is more and more accepted and applied by foundry companies. However, a large amount of waste molding sand or core sand will be produced in the resin sand casting process. If the molding sand or core sand is not recycled, , Not only pollute...

Problems solved by technology

[0003] With the continuous improvement of the quality requirements of mechanical products, the resin sand molding process is more and more accepted and applied by foundry enterprises, but in the process of resin sand casting, a large amount of waste molding sand or core sand will be produced. If the molding sand or core sand is not recycled , not only pollute the environment, but also increase the cost of the enterprise. Common used sand recovery methods include thermal recovery and wet recovery, but these methods have problems of high cost, low efficiency, and large pollution
