[0026] Compared with the existing technology, the utility model provides a multifunctional casting sand removal machine with the following beneficial effects:
[0027] Efficient removal of sticky sand
[0028] Sodium chloride solution spraying: The sodium chloride solution in the liquid storage tank is pumped to the spray pipe through the liquid pump and evenly sprayed on the surface of the casting through the nozzle. This spraying method ensures that the solution can fully cover the surface of the casting and accelerates the corrosion process of sand adhesion.
[0029] Corrosion process: Sodium chloride solution forms an electrolyte film on the surface of the casting, which accelerates the corrosion of the sticky sand. After a certain period of spraying treatment, the sticky sand is gradually corroded and loosened, providing a good foundation for subsequent shot blasting.
[0030] Shot blasting: The casting enters the shot blasting room from the spraying room. The vibrating shot blasting machine uses the vibrating steel shot flow to carry out abrasive, and completely removes the sticky sand on the surface of the casting. This method of combining corrosion and physical removal greatly improves the efficiency of sticky sand removal.
[0031] Reduce scrap rate
[0032] Improve the qualified rate of finished products: Through the efficient sand removal method, the qualified rate of finished castings is improved and unnecessary waste is reduced.
