Abstract: A treating system for selecting and recovering reusable materials from used composite plastics is constituted by a crushing process, a cleaning and grading process and a plastics separation process. The treating system for the composite plastics is constituted by combining the cleaning and grading process in which a mechanical impact force and a friction force are applied to the plastic crushed pieces so as to clean the plastics and form the gain size of the plastics, and the plastics separation process with using a hydrocyclone. Accordingly, a selecting accuracy of the selected and recovered plastics is significantly improved and the plastics are separated to high-purity plastics, whereby it is possible to utilize the recovered plastics as recycled materials.

Abstract: A discarded industrial product recycling system capable of acquiring pertinent data required for processings of discarded industrial products such as discarders, reception dates, persons responsible for disposal, disposal dates and so forth for selecting proper disposal for each of the discarded industrial products while automatizing the article data acquisition to a possible maximum for enhancing the enhance disposal rate. An electronic tag (radio-frequency identifier tag) is attached to each of discarded industrial products to allow data required for the processing to be written and read by readers/writers. At a time point and a place where a discarded industrial product is received, basic data required for the processing of that article is written in the electronic tag. Pertinent processing route for each of the manufactured articles is decided by reading the data from the electronic tag while writing additional data in the tag as occasion requires.

Abstract: A wrapping machine of the present invention comprises a wrapping portion for wrapping a material, a film feeder for feeding a wrapping material (film) to the wrapping portion from a film roller, a material feeder for feeding the material to the wrapping portion, a film folding device for wrapping the material with the film at the wrapping portion, and a material transfer device for transferring the wrapped material. When a material is placed on a conveyer of the material feeder, the material abuts on a stopper to temporarily stop, and then is transferred to a lift of the material feeder. The width and length of the material are detected during the transfer. The lift then moves upward to supply the material to the wrapping portion. The film drawn from the film roller by the film feeder is supplied to the wrapping portion where the material abuts on the film from below so that the upper portion of the material is covered with the film. The film is then folded under the material by the film folding device.

Abstract: In a treatment system of radioactive waste solution including sodium sulfate generated from a boiling water type nuclear reactor, waste solution is fed into a thin film evaporator where the waste solution is evaporated and made into powder while precipitating in a peripheral surface of the evaporator vessel. The surface of the precipitated solid is wiped by rotating wiper blades and removed off as radioactive solid powder. The rotational speed of a rotor to which the wiper blades are secured is controlled at a minimum and necessary rotational speed which contributes to make the waste solution into the powder so that the rate of worn out of the wiper blade is decreased.
