摘要： PROBLEM TO BE SOLVED: To provide a waste disintegrating treatment method capable of cutting a copper wire to be cut without fixing the same and recovering copper from the waste certainly and easily by low energy. SOLUTION: In a method for the disintegrating treatment of waste containing a copper part comprising tough pitch copper, tough pitch copper in waste is subjected to embrittlement treatment to facilitate the disintegration treatment of waste. The embrittlement treatment is performed in a high temp. environment in the presence of hydrogen and fluorine and, concretely, a hydrocarbon bond- containing compd. and a fluorine atom-containing compd. are allowed to be present in the waste and this waste is heated at 500-1050 deg.C in an oxygen-free or low oxygen atmosphere to embrittle tough pitch copper in the waste to facilitate the disintegration of the waste. That is, the waste is a waste motor and a copper wire can be separated by cutting an embrittled copper wire.

摘要： PROBLEM TO BE SOLVED: To reduce the used amount of the cutting oil while efficiently eliminating the chips so as to improve the effect of injection of the oil mist by performing a process for spraying the gas to a cutting tool so as to eliminate the chips adhered to the cutting tool with the predetermined timing. SOLUTION: When the predetermined quantity of the chips is adhered to a cutting tool 12, the signal for opening a solenoid valve 46 for the predetermined time is output from a timer 44 to the solenoid valve 46. With this structure, in an air injecting device 30, the compressed air stored in an accumulator tank 34 is injected by a compressor 32 from an injection nozzle 42 to the cutting tool 12 for the predetermined time so as to eliminate the chips adhered to the cutting tool 12. In this case, injection of the oil mist can be stopped during the injection of the air. Pressure of the accumulator tank 34 is returned to the predetermined value by the operation of the compressor 32 during the time when the solenoid valve 46 is closed.

摘要： PROBLEM TO BE SOLVED: To absorb the stretching of a rail due to a temperature change by providing a pair of arm parts which are separated from each other by a specified distance and extend in parallel and fixing rails on the tip of each of the arm parts in such a manner that the end parts of the rails are separated from each other at a rail joint. SOLUTION: A rail bracket 12 supporting the guide rail 10 of a sludge raker has a pair of arm parts 30 which are separated from each other by a specified distance and extend in parallel. Each of the arm parts 30 is formed of a spacer which is sandwiched between the bases of paired plain resin plates 31 and fastened there. In addition, A support plate 33 is installed horizontally on the tip of each of the arm parts 30, while the base end of the arm part 30 is connected to a mounting seat 34, which is, in turn, fixed to the lateral wall 2a of a settlement pond 2. Further, on the upper face of the support plates 33, a gap S which extends obliquely through the end parts of the rail 10 at the joint of the rail 10, is disposed in such way that the gap S spans over both support plates 33 across the gap S itself. The end parts of the rail 10 are fixed to the support plates 33 by driving a tapping screw 36 into each of the support plates 33 from above.

摘要： PURPOSE:To lighten the dust removing device, by using a light, flexible, and anti-corrosive plastic resin in major part items of a bar screen or the like of the dust removing device installed in a waterway and specifying the elongation at the breaking time of the plastic material. CONSTITUTION:At least one of front screen 11, main screen 12, screen beam rake 13, guide plates 20, 21, side frame 25, etc., is made of a flexible, light, and anti-corrosive plastic resin or a composite material composed of metal and plastic resin. A ring-opening polymer of norbornene monomer of tricyclic structures or more reformed by two-liquid mixed elastomer which can be molded in a short time at an ordinary temperature, is used as the plastic material. Otherwise, a thermoplastic resin like ABS resin, polypropylene resin, etc., is used. These resin should be elastic and tough, having 10-100% elongation on breaking. In this way, a permanent strain is prevented even against an impulse and corrosion resistance is improved and it is made measurable and also molded as a unit.
