Description
Technical Field
[0001] This utility model relates to the field of waste sand recycling technology, specifically a crushing and vibrating device for waste sand recycling. Background Technology
[0002] Waste sand is the casting sand waste that peels off the surface of the casting after sand casting. Its main components are quartz sand, clay, and organic residues. Through physical treatment processes such as crushing, magnetic separation, and screening, waste sand can be converted into reusable recycled sand, reducing production costs and environmental pollution. Waste sand recycling is an important part of the foundry industry, which can reduce production costs and reduce environmental pollution. Traditional waste sand recycling devices typically employ crushing and screening processes, but these methods suffer from several problems: fixed crushing rollers are difficult to adapt to waste sand of different particle sizes, which can lead to uneven crushing or blockages. Additionally, during vibrating screening, waste sand tends to accumulate at the edges of the screen, affecting screening efficiency, and metal impurities are difficult to separate. Therefore, we propose a crushing and vibrating device for waste sand recycling. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a crushing vibration device for old sand recycling. The device uses adjustable-gap crushing rollers to accurately control the crushing particle size of sand. Combined with high-frequency vibrating screening and automatic cleaning functions, it significantly improves screening efficiency and prevents clogging. The built-in magnet device can effectively adsorb metal impurities and improve the purity of sand, which can effectively solve the problems in the background technology.
