Regenerative apparatus for waste molding sand and closed-loop sand reclaim type casting manufacturing system using of the same

摘要

The present invention relates to a reclaiming technology of a waste ladle, which is capable of collecting, regenerating and regenerating sand for casting from a production site into a closed loop structure, and a sand reclamation casting manufacturing system using the same. The present invention relates to a washing machine comprising a washing means for receiving a waste paper and washing it together with a washing liquid, a drying means for receiving and drying the washed washing yarn from the washing means, And a storage and supply means for supplying the regenerated used yarn to a molding apparatus for producing a mold, wherein the cleaning means includes a first cleaning tank for cleaning and cleaning the waste plastics with the cleaning liquid by a blade rotating around the first rotation axis, And a second cleaning tank communicating with the first cleaning tank to receive the cleaning yarn washed and washed first and secondly cleaning the received cleaning yarn and transferring the cleaning yarn in one direction simultaneously with the cleaning, The tank has a second rotation axis corresponding to a transverse direction length of the second washing tank and having a rotation center in a direction intersecting with the first rotation axis, A plurality of blade assemblies provided in a plurality of the second rotary shafts and partially overlapping each other, wherein the blade combination includes a moving blade forming a relatively small turning radius around the rotating shaft, Are provided so as to intersect with each other. According to the thus configured waste grinding machine recycling apparatus, the waste grinding sand produced during the manufacturing process of the casting is recovered and recovered directly at the production site of the casting, and the recovered waste grinding sand is supplied as a raw material for the production of the mold, A very high casting production system can be provided. In addition, since the utilization of the waste maggot is improved as described above, the consumption of the yarn is reduced and the cost of the yarn is reduced.
