あるが、この酸化物を除去することができるのである。"Function" The device according to the present invention is configured as described above, and has two functions:
Therefore, when passed through the electrode plate, the electric current on the temporary surface is
Fine bubbles of hydrogen, oxygen, etc. are generated, and when these bubbles float to the surface, they adhere to floating substances in the stock solution and float, forming a concentrated layer of floating substances on the liquid surface. This a-cotton layer is appropriately scraped off and separated from the undiluted solution, but in this series of a-condensation separation operations, in the present invention, the Since the device is equipped with a device to scrape off deposits on the surface, dirt and air bubbles will not remain on the surface (and the electrode surface will always be clean and maintain high electrolytic capacity. In other words, the surface of the anode plate Oxygen is generated, and this oxygen reacts with the electrode plates to form oxides, which obstruct the conduction of electricity, but this oxide can be removed.

This reduced floating material can be scraped off by a skimmer 5 and taken out via a tofu 6. In the above-described operation for producing and removing floating substances, in the present invention, the scraper 4 comes into sliding contact with the surface of the anode plate 3 to remove dirt on the surface, so that the electrolytic ability is not reduced, and the anode Since the plate 3 is rotating, the stock solution flows between the positive and negative electrode plates. Therefore, floating objects and bubbles do not remain between the electrode plates, do not impede electrolytic discharge, and floating objects can be smoothly floated and separated from the stock solution.
