Crushing device used for casting sand recovery in casting process

Abstract

The invention discloses a crushing device used for casting sand recovery in the casting process. The crushing device used for casting sand recovery in the casting process comprises a device body. A crushing box is integrally formed at the top end of the device body. A hopper is arranged at the top end of the crushing box. A driving motor is mounted on the left side face of the device body througha support. A raw material collection box is arranged at the bottom of an inner cavity of the device body. A notch communicating with the inner cavity of the device body is formed in the bottom of thefront side of the device body. A through groove communicating with the inner cavity of the device body is formed in the bottom of the right side face of the device body. According to the crushing device used for casting sand recovery in the casting process, blocky casting sand adhering together is sheared through two crushing rollers which rotate oppositely, so that the large blocky casting sand adhering together is loosened and dispersed; then the dispersed casting sand is ground through two extruding rollers so as to be separated; only the casting sand adhering together is dispersed and separated through the crushing method, the casting sand is not crushed, so that the original size of the casting sand is kept, and the problem that the quality of the casting sand is affected due to the fact that the casting sand is excessively crushed is solved.

Description

technical field [0001] The invention relates to the field of foundry processing, in particular to a crushing device for recycling moulding sand in foundry processing. Background technique [0002] Casting is a metal thermal processing technology that human beings mastered relatively early, with a history of about 6,000 years. China has entered the heyday of bronze castings between about 1700 BC and 1000 BC, and the craftsmanship has reached a very high level. Casting refers to the forming method of pouring the smelted metal into the mold, and after it solidifies to obtain a casting with a certain shape and performance, the metal parts obtained by the casting method are called castings. Most of the cast material is a metal that is originally solid but heated to a liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and there are many casting methods, mainly sand casting, metal casting, pressure casting, centrifugal casting and melting. Die casting, etc., amo...
