Description

Technical Field

[0001] The utility model belongs to the technical field of recycling used foundry sand, and particularly relates to an environmentally friendly waste sand processing device for foundry. Background Art

[0002] Waste sand treatment is a crucial component of the foundry industry, as the casting process generates significant quantities of waste sand. Improper handling of this waste sand not only wastes resources but can also pollute the environment. If the binder in the sand has not undergone irreversible changes, the sand in this state can be restored to its original properties by removing impurities, cooling it with suction, and remixing it. Physical screening of sand impurities is used to separate large impurities from fine particles. Prior to screening, the sand must be allowed to cool to the specified handling temperature.

[0003] In some existing molding sand recycling processes, impurity screening and ash absorption and cooling are carried out in steps, which makes the process time-consuming and is not conducive to improving the efficiency of molding sand recycling. Some processes use vibrating screening equipment to process molding sand, which generates a lot of noise and dust, pollutes the working environment, is less environmentally friendly, and is inconvenient to use. Utility Model Content
