Description

Technical Field

[0001] The utility model belongs to the field of dust removal and purification equipment, and in particular relates to a simple dust collector used for cleaning slag in casting sand molds. Background Art

[0002] Casting is one of the basic processes in the modern machinery manufacturing industry. As a metal heat processing technology, casting has been very mature in my country. Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank.

[0003] Nowadays, sand molds are generally used for casting. During the manufacturing process of sand molds, some sand and dust will fall from the inside of the sand molds. If the sand and dust enter the casting workpiece, it will form slag inclusions, causing the workpiece to be unqualified. In today's molding process, high-pressure gas is often used to blow away the sand and dust in the sand molds. However, during the blowing process, the sand and dust will fly everywhere, which not only causes environmental pollution, but also easily enters the already sorted sand molds. The best way is to use a vacuum cleaner to suck away the sand and dust, but because the casting production environment is relatively harsh, today's vacuum cleaners have a relatively sophisticated structure. If used in a casting environment, it will greatly reduce the service life. Utility Model Content
