The cleaning liquid was injected into the cleaning tank 22 and the cleaning tank 3 of the main cleaning apparatus 1 up to a predetermined liquid level. Alloxan C (trade name; Gospel Kako Co., Ltd.), which is a nonionic surfactant, is used as the cleaning liquid.
1% by weight aqueous solution of (produced) The liquid temperature of this cleaning liquid was about 50 ° C. and the pH was 10-11. Then, after driving the conveying devices 4 and 23 of the main cleaning device 1 and the preliminary cleaning device 2, the titanium-containing copper alloy cutting chips are finely crushed into the charging port 20 of the preliminary cleaning device 2 at a speed of 5 kg / min. I put it in. The thrown cutting chips fall to the bottom of the preliminary cleaning device 2 and are scraped by the scraper 5 of the transport device 23 to be discharged to the carry-out port 2.
Preliminary cleaning was performed with a cleaning agent while gradually moving to the 1st side. Then, after the cleaning liquid is removed from the cutting waste by the inclined portion 28 of the preliminary cleaning device 2, the cutting waste drops from the carry-out port 21 to the input port 8 of the main cleaning device 1. When it is confirmed that the cutting waste has entered the main cleaning device 1, the cleaning liquid is supplied to the distribution pipe 17 of the cleaning liquid spraying device 5 of the main cleaning device 1 to supply the spray nozzle 16
The cleaning liquid was sprayed and the ultrasonic generator 6 was driven. The cutting chips that have moved to below the spray nozzle 16 by the transport device 4 rise up from the bottom of the cleaning tank 3 by the cleaning liquid sprayed from the spray nozzle 16. Then, in this state, the ultrasonic wave was applied from the ultrasonic wave generator 6 and vibrated finely. The cutting chips that have passed under the spray nozzle 16 and the ultrasonic generator 6 in this way are sent to the inclined portion 10 by the carrying device 4 to remove the cleaning liquid, and then discharged from the carry-out port 7. In this example, the cutting waste passed through the preliminary cleaning device 2 in about 1 minute and passed through the main cleaning device 1 in about 3 minutes.

明した。Carbon analysis was performed on the cutting waste thus treated, the cutting waste before processing, and the cutting waste that passed through only the preliminary cleaning device 2. This carbon analysis is a test in which the amount of carbon dioxide gas generated by melting and burning the sample by induction heating by adding a combustion improver to the sample is calculated from the difference in thermal conductivity, and the amount of carbon in the sample is calculated from this amount of carbon dioxide gas. Is the law.
As a result of this carbon analysis, the cutting waste before treatment has a carbon content of 1
While the amount of carbon was 000 ppm, the amount of carbon in the cutting waste passing through only the preliminary cleaning device 2 was 200 ppm, and the amount of carbon in the cutting waste treated by the preliminary cleaning device 2 and the main cleaning device 1 was 7 ppm.
It was significantly reduced to 0 ppm, and it was proved that the carbon adhering to the cutting waste could be reliably removed by the device of the present invention.

を、ムラ無く、効率良く得ることができる。This cleaning device has a charging port 8 for charging cutting chips.
And a cleaning tank 9 containing a cleaning liquid 9 having an outlet 7 for discharging the processed cutting waste, and a cleaning liquid 9 in the cleaning tank 3.
A transport device 4 for moving the cutting waste dipped in the liquid from the input port 8 toward the outlet 7, a cleaning liquid spraying device 5 for spraying a cleaning liquid toward the cutting waste transported by the transport device 4, and a moving cutting waste. Since it is a device including an ultrasonic wave generator 6 for irradiating ultrasonic waves, the inlet 8 of the main cleaning device 1
When the cutting debris is put in, the cutting debris is conveyed to the carry-out port 7 by the conveying device 4. The cleaning liquid is stored in the cleaning tank 3, and the cutting chips move while being immersed in the cleaning liquid 9 to be cleaned. Further, with respect to the cutting chips conveyed by the conveying device 4, the cleaning liquid is sprayed from the cleaning liquid spraying device 5 to bring the cutting chips into a floating state so as to be separated from each other. Then, in this state, the cutting waste is irradiated with ultrasonic waves from the ultrasonic generator to finely vibrate the cutting waste. Therefore, according to this cleaning device, the ultrasonic irradiation is spread even to the individual cutting chips, and the contaminants such as oil, carbon, and phosphorus that have entered the recesses of the cutting chips can be reliably removed. Further, according to this cleaning device, it is possible to efficiently obtain cutting scraps having an extremely small amount of adhered contaminants such as oil and carbon without unevenness.

率良く得ることができる。As described above, the apparatus for cleaning metal scraps of the present invention includes a cleaning tank containing a cleaning liquid, which has an inlet for charging metal scraps and an outlet for discharging processed metal scraps, and A transport device that moves metal scraps soaked in the cleaning liquid in the cleaning tank from the inlet to the outlet, a cleaning liquid spray device that sprays the cleaning liquid toward the metal scraps transported by this transport device, and a moving metal scrap Since the device is composed of an ultrasonic wave generator that radiates ultrasonic waves, when metal scrap is thrown into the charging port, the metal scrap is transported toward the carry-out port by the transport device. A cleaning liquid is stored in the cleaning tank, and the metal scraps are moved while being immersed in the cleaning liquid to be cleaned. Further, with respect to the metal scraps transported by the transport device, the cleaning liquid is sprayed from the cleaning liquid spraying device to bring the metal scraps into a floating state so as to be separated from each other. Then, in this state, the metal scraps are irradiated with ultrasonic waves from the ultrasonic generator to finely vibrate the metal scraps. Therefore, according to this cleaning device, the ultrasonic irradiation reaches even the individual metal scraps, and even the oil, carbon, phosphorus, etc. that have entered the recesses of the metal scraps can be removed, and the metal scraps with extremely low adhered amounts of these contaminants can be removed. It can be efficiently obtained without unevenness.
