VOLUME REDUCING METHOD AND VOLUME REDUCING DEVICE FOR SOLID WASTE

摘要

PROBLEM TO BE SOLVED: To reduce the amount of dust produced and recover a slight amount of dust produced, by disposing a gripped solid waste in water so as to be surrounded by a cylindrical dust recovering tank, and pressing outer parts of the solid waste to reduce its volume.;SOLUTION: A solid waste 4 is gripped by its upper part by a crane or the like, lowered from an opening part 13 into a dust recovery tank 3, stopped at a position where its bottom part makes contact with a taper part 16, and kept in an upright state with a lower part of the solid waste 4 held by a hold part 15. A pressing means 5 is lowered from the opening part 13 into the dust recovering tank 3 by a lifting device, and the solid waste 4 is supported by being sandwiched from both sides between a pair of pressing parts 18. When a pressing command is outputted from an oil-pressure control part, hydraulic cylinders 20 of the respective pressing parts 18 are synchronously driven and in turn compress the solid waste 4 to reduce its volume. Thereafter, the solid waste 4 with a reduced volume is gripped by its upper part and moved to a storing place above a pool 1. Dust from the solid waste 4 settles in the dust recovery tank 3 and is discharged by a drainage pump 7 into a separation device 8 by being accompanied by the water 2.;COPYRIGHT: (C)2000,JPO
