Description

Sand loosening machine with anti-blocking dynamic and static comb type structure

Technical Field

The utility model relates to the technical field of sand loosening machines, in particular to a sand loosening machine with an anti-blocking dynamic and static comb type structure.

Background

In the field of mechanical casting, molding sand casting is mainly adopted for casting. Statistically, approximately one ton of used sand is produced per ton of cast. Therefore, the sand mold for casting is generally recycled after the casting is completed, from the viewpoint of cost saving and pollution reduction. The used sand blocks stripped from the castings need to be crushed again, screened to meet certain granularity requirements, and then recycled. And in the recovery process, a certain amount of water needs to be added to meet the requirement of sand for sand mold. The fine sand is easily agglomerated after being added with water, and therefore, a sand loosening operation is required before the fine sand becomes sand for sand molding.

The sand loosening machine is mainly used for loosening various clay type molding sand, can be arranged below a discharge opening of a sand mixer or at a rotary discharge position of a belt conveyor, has strong applicability, can be used alone, and can also be arranged on a mechanized sand treatment production line.
