摘要： PROBLEM TO BE SOLVED: To recover refrigerant CFC dissolving into refrigerating machine oil by making a hole on the lower surface side of a fixed recovering machine under negative pressure state, recovering a gas/liquid mixture of refrigerant and refrigerating machine oil and separating the refrigerant from the refrigerating machine oil. SOLUTION: A machine to be recovered 15 is fixed onto a carrier 16 by means of a fixing unit with the part exposing a compressor 12 being directed downward and the seal part 18 of a drill 3 is pressed against the compressor 12 from below. A change-over valve 7 is turned to the vacuum pump 11 side and the seal part 18 is sucked to bring about negative pressure state. Subsequently, the change-over valve 7 is turned to the refrigerant/refrigerating machine oil separator 20 side and a hole is made through the shell of the compressor 12 by means of a drill 3. Ejected gaseous refrigerant and refrigerating machine oil are introduced to the separator 20 and oil is removed from the gaseous refrigerant when it ascends through an oil mist separator 25 and then it is introduced to a gaseous refrigerant recovery unit 50. Refrigerating machine oil is heated in a tank 21 by means of a heater 29 in order to accelerate separation of refrigerant.

摘要： PURPOSE: To automatically unload a cargo carried in by a track or the like, further to perform successively stably supplying this cargo to a treatment facility or the like, in the waste treatment facility or the like. CONSTITUTION: A treated object 3 is forcedly transfer loaded to an unloader conveyer 4 by an automatic unloading device 1 from a truck parked in a parking area, further to be transfer fed to an inclined conveyer 6 by a transfer feed conveyer 5, and to be made supplyable to a treatment equipment in the next process while preventing double transfer feeding, adjacent transfer feeding, etc., of the treated object 3. Thus by shortening work time by unloading automatization, treating capacity of a treating facility total unit can be improved, and since the treated object brought in by the truck or the like can be unloaded in one lot on the unloader conveyer, reducing a stockyard and stably automatic supply to a treatment facility after unloading are performed, so that a large amount of treated objects can be more efficiently unloaded to be treated.

摘要： PURPOSE: To provide a mixture sorting apparatus which prevents the deterioration of sorting efficiency due to the increase of retained materials to be sorted in the apparatus and is adaptable to continuous and large scale sorting treatment while keeping a good condition of sorting precision by controlling a feed amount and a delivery amount of a mixture of crushed pieces of waste plastics etc., during the continuous sorting. CONSTITUTION: The amount of materials to be sorted in a specific gravity sorting tank 1 is kept in a range in which continuous operation is possible by constitution in which a rotary valve 4 and the rotational speeds of the driving devices 15, 13, 14 of delivery apparatuses 6, 7 are controlled by a controller 8 on the basis of the weight of the materials to be sorted measured by delivered material weight integration devices 11, 12. A rotary valve having more than one spacings formed by more than one attachable/detachable blades is installed in the outlet part of a mixture feed hopper, and the control of the revolution of the rotary valve and the change of the total spacing volume by the change of the number of blades are combined so that the feed amount can be adjusted optionally correspondingly to the size of the mixture.

摘要： PURPOSE: To provide a method and apparatus for treating waste in which waste electric appliances, etc., are peeled and crushed by each type of material and sorted to recover valuable resources. CONSTITUTION: A motor, etc., removed by a metal block sorting means 4 are cooled by a cooler 9 and fed to a crusher 5 to be crushed at low temperatures. The residual case, at the same time, is fed to the crusher 5 as it remains at normal temperature. In the crusher 5, both low-temperature crushing and high- temperature crushing are carried out simultaneously, and the crushed pieces are discharged as a mixture and, in the next process, are sorted by a metal sorting apparatus 7, a plastic sorting apparatus 8, etc., by each type of material to be recovered as resources. In this way, a recycling treatment apparatus can be installed efficiently in a given space.

摘要： PURPOSE:To individually separate aluminum and copper from a mixture including them by providing a throw-in hole, a carrying means and an alternating magnetic field imparting means for the mixture including copper and aluminum and a hopper for collecting aluminum and providing an air blow-in hole on the outlet part near the hopper. CONSTITUTION:A mixture of nonferrous metal, such as aluminum and copper, and nonmetal, such as glass and wood or iron, is fed from a feed throw-in hole 7 and carried to on a head drum 5 by a rotary belt 2 and influenced by alternating magnetic field generated by the rotation of a permanent magnet rotor 1, causing eddy current to be generated in electric conductors, such as aluminum and copper. Since the magnetic field generated in the electric conductors by the eddy current has the same pole as alternating magnetic field generated by the rotation of the rotor 1, the electric conductors are repulsed and hop from the rotor 1 and, by blowing in air from an air blow-in hole 3 installed in the outlet part of the rotor, hopped aluminum of low specific gravity, etc., are blown off and recovered by an aluminum recovery hopper 8 and copper, etc., fall intact and are recovered in a copper recovery hopper 9.

摘要： PURPOSE:To facilitate the stabilization of a rotational speed and the efficient utilization of driving energy by a method wherein a rotary induction machine which has a rotary shaft which is coupled with the output shaft of a prime mover in relation of mutual torque transmission is provided and the prime mover is operated while the rotary induction machine is always connected to a power supply. CONSTITUTION:A rotary induction machine 2 which has a synchronous rotational speed equal to the rated rotational speed of a prime mover 1 and, further, has a rotary shaft coupled with the output shaft of the prime mover 1 in relation of mutual torque transmission and a control means which always keeps the rotary induction machine connected to a driving power supply. A rotational speed is stabilized by the variation of an operation mode shown by the rotary induction machine 2 in accordance with the difference between the rotation output of the prime mover 1 and the power required by a load. With this constitution, the variation of the rotational speed can be suppressed and the sufficiently stable operation can automatically be realized while driving energy whose supply rate is fluctuating is efficiently utilized.
