摘要:
A system for recycling reusable resin mold products recovered from discarded apparatuses is disclosed. This recycling system includes a crushing system for crushing resin mold products one kind by one kind into crushed resinous pieces and packing the same in a bag, a classification system for irradiating a light beam to the resin in the bag and classifying the bags into respective kinds of resins based on a reflected beam therefrom, a cleaning system for separately cleaning the respective kind of crushed resinous pieces taken out of the bag to remove foreign matters adhered onto the surfaces of the crushed resinous pieces therefrom, and a recovery system for recovering the cleaned crushed resinous pieces.

A cleaning apparatus capable of sufficiently removing foreign matters such as coating or labels from surfaces of crushed pieces of the collected polymeric mold product is provided. The cleaning apparatus includes a cleaning bath provided with a rotary shaft extending in the longitudinal direction and having a water supply port, a drainage port as well as an introduction port and a discharging port for polymeric pieces, screw sections having a screw provided on the rotary shaft and flow-path restricting sections having stationary plates standing upright from the inner surface of the cleaning bath to restricting the advancement of water caused by the screw, wherein at least part of a surface of the stationary plate is roughened.

A modular blade assembly having base and blade components and at least one keyplate aligning the base and blade components. The keyplate rests in a recessed groove in each of the base and blade components. Each of the dimensions of the recessed groove in which the keyplate rests is less than the dimensions of the surface in which the groove is disposed.

The invention relates to a process for recovering monomeric units of a nylon from carpet material. The carpet material includes fibres containing nylon bound to a backing containing one or more non-nylon components. The carpet material contains between 15 and 35 wt. % of the nylon. The process includes: a) mechanically separating the carpet material into an enriched carpet mixture containing between 35 and 55 wt. % of said nylon and into a depleted carpet mixture having a lower content of nylon than the carpet material; and b) exposing the enriched carpet mixture to conditions at which depolymerization of the nylon is effected.

The invention provides an apparatus and method for the recovery of ink from inkjet cartridges. The apparatus includes means (1) for breaking the ink cartridges into pieces, thereby releasing any ink and compressible material or sponge from within the otherwise substantially sealed cartridges; a washing stage (2) whereby ink is removed with solvent; and a draining stage (3) where excess solvent is drained from the cartridge pieces.

A raw material supplier manufactures raw material for a plastic substrate by means of a raw material manufacturing device. A disk presser manufactures a substrate from the raw material by means of an optical disk manufacturing device, manufactures an optical disk by laminating the substrate sequentially with the recording layer and the reflecting layer, and records predetermined information on the disk by means of an information recording device. The disk presser recovers a pure and lucent plastic substrate from a disk fallen into disuse, so as to supply the substrate to the raw material supplier.

The invention describes a blade mill for grinding plastic material with a rotor which is driven in rotation inside a grinding chamber and has a plurality of radially outwards-pointing cutter blades distributed around its circumference and a plurality of stationary, radially inwards-pointing stator blades projecting into the grinding chamber and forming a blade gap with the cutter blades, wherein cutting spaces widening radially outwards in a crescent shape and located radially outside the turning circle of the rotating cutter blades are located ahead of the stator blades in the direction of rotation of the rotor. To prevent the plastic material which is to be ground from backing up in the cutting spaces and from being crushed against the wall of the screen baskets, the invention provides that the motion path of the rotor blades extend eccentrically with respect to the axis defined by the screen baskets. Relaxation spaces in which the plastic material is accommodated and which extend over a large rotational angle of the rotor blades are thereby formed in the gap between the wall of the screen baskets and the orbital path of the rotor blades. This allows the driving power of the drive motor to be significantly reduced for a given cutting performance.
摘要:
A refrigerant gas is collected and a compressor is removed from a discarded refrigerator, a heat-insulating housing including a heat insulator is cut/processed and separated into a plurality of pieces, and the pieces are compressed/processed by compression rollers opposing each other so as to collect a gas contained in the heat insulator. In accordance with this method, substantially no gas contained in the heat insulator is diffused at the time of cutting the heat-insulating housing, and the gas can be collected at a high concentration because it is collected by being allowed to leak out at the time of compressing. Furthermore, by using the compression rollers, closed-cells in the heat insulator can be crushed easily, thereby collecting the gas completely and reliably. Thus, it is possible to collect a foaming gas contained in the heat insulator efficiently and disassemble a refrigerator at low cost without increasing the size of-equipment and an installation space.
