Problems solved by technology
[0004] However, in the above-mentioned conventional cleaning device, since the used cooling liquid (processing liquid) is supplied by dropping into the storage tank, air bubbles are generated in the used cooling liquid stored in the storage tank. It is difficult to spread to all corners of the used cooling liquid stored in the storage tank. In addition, because the residence time of the bubbles in the used cooling liquid is relatively short, it is difficult to form used cooling liquid in the storage tank. A state where more oxygen is dissolved in the coolant
Therefore, anaerobic bacteria are more likely to multiply in the used coolant stored in the storage tank, which causes bad odor
In addition, if the surface of the used coolant stored in the storage tank is covered with foreign matter such as oil, bacterial dead remains, cutting powder, etc., the used coolant will not be able to spread oxygen, which will easily accelerate the growth of anaerobic bacteria.

Embodiment Construction
[0066] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0067] The purification device of the first embodiment of the present invention is as figure 1 constituted as shown. This purification device is a device capable of purifying and reusing coolant (processing liquid) used in processing machines such as lathes and milling machines.
[0068] exist figure 1 In this purification device, there is a liquid storage tank 10 for storing cooling liquid (processing liquid) L, and the used cooling liquid from the processing machine is stored in the liquid storage tank 10 through the introduction pipe 11, and the cleaning process is carried out in the liquid storage tank 10. The purified used coolant L can be returned to the processing machine through the delivery pipe 12 . In addition, this cleaning device has a foam generator 20 (foam generator body), a pump 21 and an air cylinder 22 . The pump 21 supplies the used coolant L suc...

To provide a cleaning apparatus in which a larger amount of gas such as oxygen can be thoroughly spread in a used treating liquid. The cleaning apparatus for cleaning the treating liquid used in a processing machine includes: a liquid storage tank (10); bubble production mechanisms (11, 21, 22) for producing bubbles in the used treating liquid and discharging the bubble-containing used treating liquid; and a supply part 26 for guiding the bubble-containing used treating liquid to be discharged from the bubble production mechanisms to the liquid storage tank (10) and supplying the guided bubble-containing used treating liquid to the liquid storage tank (10) while spouting the guided bubble-containing used treating liquid toward the bottom of the liquid storage tank.
Description
technical field [0001] The present invention relates to a purifying device for purifying processing liquids such as cooling liquids used in processing machines. Background technique [0002] In the past, a cooling liquid purification device has been proposed, which purifies the cooling liquid (treatment liquid) used for lubrication and cooling of cutting parts in processing machines such as lathes and milling machines so that it can be used repeatedly (refer to patent Literature 1). In this conventional cleaning device, the used cooling liquid from the processing machine is supplied to the storage tank in a state where the magnetic substance has been removed, so that air bubbles (foam) are generated in the cooling liquid stored in the storage tank, When the air bubbles float up, they adhere to the foreign matter in the cooling liquid, and the foreign matter floats up to the surface of the cooling liquid. The cooling liquid is purified by recovering the foreign matter float...
