Description

Technical Field

[0001] The utility model belongs to the technical field of manhole cover production. Specifically, it particularly relates to an automatic sand material recycling device for the production of ductile iron manhole covers. Background Technique

[0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. They can be classified into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Ductile iron manhole covers belong to a type of metal manhole cover. When ductile iron manhole covers are cast at high temperatures, the outer layer needs to be coated with a sand layer made of quartz sand, clay, etc. After cooling, the sand layer needs to be removed by vibration.
