Problems solved by technology

[0002] During the entire recycling process, the molding sand is basically in a closed state or in a poorly ventilated state. The temperature of the castings close to the molding sand reaches 300-500°C after high temperature, and the sand temperature is above 100°C. It is difficult for the molding sand to drop to the operating temperature in a short time. Natural cooling The cooling effect cannot be achieved due to various factors and time. The high temperature of the molding sand will deteriorate the heat dissipation conditions of the casting during the next casting, seriously affect the metallographic structure and mechanical properties of the casting, and increase the possibility of pores in the casting.
In the traditional technology, the principle of humidification and cooling is generally used, the cooling effect is poor and it will affect the next use, and it can no longer meet the needs of molding sand cooling

Abstract

The invention discloses an environmental-protection molding sand cooling recovery device. The device comprises a tower body, and a first separation plate, a second separation plate and a blanking collecting plate arranged in the tower body in sequence from top to bottom; a crushing bin is fixedly connected with a fixed inclined surface end, a slide inclined surface end and a first driving cam in sequence from left to right; a first return spring is arranged between the slide inclined surface end and the first separation plate; the first driving cam is matched with the right side surface of theslide inclined surface end, and can butt against the slide inclined surface end to move to the left side to realize pressing of the first return spring; when the first return spring is reset, the slide inclined surface end can be driven to move to the right side; a discharge port is formed in the lower part of the blanking collecting plate; and the tower body is provided with a cooling intake endon the left side wall and an air collecting device on the right side wall. The device cools molding sand through the cooling intake end and the air collecting device, achieves better cooling effect,and is compact in structure, convenient to use, energy-saving, environment-friendly and suitable for wide application in cooling recovery of the molding sand.

Description

technical field [0001] The invention relates to the technical field of molding sand recycling, in particular to an environment-friendly molding sand cooling and recycling device. Background technique [0002] During the entire recycling process, the molding sand is basically in a closed state or in a poorly ventilated state. The temperature of the castings close to the molding sand reaches 300-500°C after high temperature, and the sand temperature is above 100°C. It is difficult for the molding sand to drop to the operating temperature in a short time. Natural cooling The cooling effect cannot be achieved due to various factors and time. The high temperature of the molding sand will deteriorate the heat dissipation conditions of the casting during the next casting, seriously affect the metallographic structure and mechanical properties of the casting, and increase the possibility of pores in the casting. In the traditional technology, the principle of humidification and cool...
