Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sodium silicate sand, and specifically relates to a cleaning device for sodium silicate sand regeneration sand. BACKGROUND

[0002] In modern casting industry, sodium silicate sand is widely used in the production process of various castings due to its good collapsibility, high strength and relatively low cost. However, after the completion of the casting process, sodium silicate sand will form clumps due to the action of the binder, and the surface of the sand particles will be covered with a large amount of sodium silicate binder, metal oxide and other impurities, which will prevent it from being directly reused and require regeneration treatment. The traditional sodium silicate sand regeneration treatment method has many limitations. The early simple mechanical crushing and screening method can separate part of the larger particle regeneration sand to some extent, but it is not effective in removing the impurities firmly adhered to the surface of the sand particles, which greatly reduces the reuse performance of the regenerated sand and affects the quality and production efficiency of the castings.

[0003] Some existing regeneration sand cleaning devices have deficiencies in automation, requiring a large amount of manual intervention, which not only increases the labor intensity, but also affects the cleaning quality of the regenerated sand and the stability of the production due to human operation errors.
