摘要： PROBLEM TO BE SOLVED: To provide a structure capable of easily adjusting a downward drainage rate of a liquid cyclone which separates materials mixed with two kinds of the materials by each of the materials.
SOLUTION: The liquid cyclone is constituted by inserting a barrel-shaped inner cylinder 5 into an external cylinder 2 formed to a conical shape in its lower part and to a cylindrical shape in its upper part and discharges the specific gravity liquid flowing in from the upper part of the external cylinder from a lower opening 7 of the conical-shape section and the inner cylinder 5. The central axis of the lower opening 7 of the conical-shape section and the central axis of the inner cylinder 5 are offset, by which a lower drainage rate is changed. The inner cylinder and the lower opening are arranged in s positional relation where the mixture to be separated is higher in a separation rate, by which the desired the separation rate can be obtained.

摘要： PROBLEM TO BE SOLVED: To accurately grasp necessary data for control such as a source, the date of receipt, the executor of treatment, and the date of treatment by product, to perform the selection of proper treatment for every product, and also to improve the treatment speed in the recycle system of a waste industrial product. SOLUTION: An electronic tag (RF-ID) is fitted to a waste product to enable the reading and writing of necessary data for treatment by a reader/writer. At a point of time when and in a place where the waste product is received from a discharger, necessary basic data for treatment is written in the electronic tag 1. After that, by performing the reading or overwriting of the data, an aptitude treatment route is determined for every product. The property of plastic material is measured, and its result is written in the electronic tag 1. Classification of the decomposed parts is performed by fitting the electronic tag 1 to pallets 52-56 each, reading the data of the electronic tag 1 fitted to the waste product therein, and writing a code of the destination to classify in the tag 1 of the pallets 52-56 each based on the data.

摘要： PROBLEM TO BE SOLVED: To reduce degradation of the service life of a rope by suspending one side by the rope and a thimble rod, and suspending the other side by a plurality of ropes an a thimble rod to keep the tension of each rope to be approximately equal. SOLUTION: Two guide rails 8, 9 hold rollers 6a-6d. The movement of a cage frame in the right-to-left direction is restricted by the rollers 6a-6d, and the movement in the longitudinal direction is restricted by rollers 7a-7d. One thimble rod assembly 10a is mounted on the left side of a lower frame 1, and two thimble rod assemblies 11a, 12a are mounted on the right side. Coil springs 11b, 11b, 13b are mounted on a lower part of the lower frame of the cage. Ropes 13, 14, 15 are attached to each thimble rod assembly. When the spring constant of the coil springs of the thimble rods are equal to each other, the tensions in the right and left ropes are balanced.
