Title: Solidification device for industrial waste
Inventor: SHIIRE HIDETAKE
IPC: B65G33/24
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To enable removal of air contained in the inside or opening of solid matters by installing screw blades in a casing equipped with an entrance and an exit at the opposite end, rotating the screw blades and solidifying industrial wastes thrown in from the entrance. SOLUTION: Industrial wastes thrown into the entrance 1 of the casing 4 are compressed by the turning force of screw blades 6, solidified and forwarded to the exit 3. At the time of the solidification of the industrial wastes, the air contained in them is separated. The air is separated further more when the wastes reach the screw blades 6 the pitch P1 , P2 , P3 of which are shorter. The air so separated is exhausted outside through the outlet 10 of the casing 4. The industrial wastes, which are collected at the exit 3 of the casing 4 and solidified, are taken out by removing the lid 2 and transported to the treatment place of the wastes. The casing 4 is designed to have a flanged connection desirably so that it is dividedly detachable.
