[0002] The production process of vacuum pump castings involves melting, pouring and crystallizing metals in a vacuum environment to produce high-quality castings. During the production process, in order to prevent the castings from oxidation and rust, special cleaning equipment is usually used to post-treat the castings to remove oxides, grit and other impurities on the surface of the castings that may affect the performance of the castings.

[0003] In the existing technology, vacuum pump casting cleaning machines usually use shot blasting cleaning methods, specifically, the projectiles are sprayed at high speed onto the castings fixed inside the cleaning machine to remove surface impurities. However, since the projectiles ejected by the shot blasting machine need to be recycled, the iron filings mixed in the projectiles cannot be automatically separated and filtered during the recycling process, which affects the recycling effect of the projectiles; at the same time, the casting cannot be rotated after being fixed, resulting in some areas of the casting cannot be cleaned evenly, thus affecting the overall quality and appearance of the casting after cleaning.
