Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension and colloid component contained in tap water, sewage, etc., oil content in water-based cleaning fluid, fine sludge, and also emulsion oil in water-soluble cutting fluid, fine particles, etc. Hydrogen and oxygen bubbles generated by electrolysis that disperse inside and cause troubles, a large amount of air installed at the bottom of the device, and a floating stir flow due to bubbling of carbon gas and charge neutralization of negatively charged colloidal particles A liquid surface inclined to an elevation angle due to the flow of air and gas discharge by aggregation and agglomeration of positively charged polyvalent ions, soluble polymer ions, and insoluble hydroxide from the anode that fulfills the crosslinking action. The present invention relates to an electrolytic ion aggregating apparatus provided with a scum and a gas discharging tool that can be easily discharged to the outside along a line.

2. Description of the Related Art Conventionally, solid-liquid separation in water and sewage has been problematic because it requires a vast facility area and processing time. In addition, there is no simple means for effectively removing oil and sludge that have been emulsified and suspended in the water-based cleaning liquid and can be reused by circulation. Furthermore,
There was no means for separating and removing water-soluble cutting oil from the waste fluid of cutting fluid containing emulsified oil, which is commonly called "emulsion", and discharging only water as it is. Furthermore, there is no one that can effectively and rapidly separate and remove white turbidity, oil that becomes emulsified, and sludge that diffuses and suspends when mixed in a cleaning liquid used in an aqueous cleaning machine, and that only water can be discharged as it is.

Therefore, the applicant of the present invention has proposed that the anode should be made of a material that produces positively charged polyvalent ions, hydroxylated polymer ions, and insoluble hydroxide during electrolysis, such as aluminum and iron. We have proposed an ion aggregator that is composed of a physically and chemically stable material such as graphite and that can agglomerate and agglomerate colloidal components dispersed in a liquid by charge neutralization and crosslinking. However, there was a problem in processing scum and hydrogen gas that floated and floated in large quantities.

[0004]

That is, an electrolytic ion aggregating apparatus equipped with a scum and a gas discharging device of the present invention is a positive and negative electrode, and at the time of electrolysis, positively charged polyvalent ions, soluble polymer ions, insoluble water. An electrolytic tool made of materials such as aluminum, magnesium, and iron that generate oxides is provided to neutralize and agglomerate the negatively charged colloidal components, and to agglomerate and float by hydrogen gas and bubbling bubbles. The gist is the feature that it can be effectively discharged to the outside by guiding it to the discharge port along the ceiling lid-shaped sloping plate installed with the inside elevation angle.

According to the present invention, a positive electrode has conductivity in a liquid tank incorporated in equipment such as tap water, sewage treatment, and a washing machine, and a system, and positively charged polyvalent ions, soluble polymer ions, and insolubles during electrolysis. It is composed of aluminum and other materials that generate hydroxides, and neutralizes and crosslinks negatively charged colloidal components and suspension components that are dispersed in the liquid. Hydrogen gas and oxygen gas from both electrodes and from the bottom of the liquid tank Provided is an electrolytic ion aggregating device equipped with a scum and a gas discharge tool which is capable of easily discharging scum and gas along the inclined plate installed at an elevation angle on the upper surface of the scum discharge port by bubbling air so as to flocculate and float. It is a thing.

[0006]

That is, an electrolytic ion aggregating apparatus equipped with a scum and a gas discharging device of the present invention is provided with at least an anode material in a liquid tank in which colloid, particles having a suspension diameter, and oil are dispersed. Aluminum, magnesium,
It has conductivity such as iron, and is a positively charged polyvalent ion during electrolysis.
Dissolvable polymer ions, insoluble hydroxide, negatively charged colloid, suspension components charge neutralization, aggregation by cross-linking,
The feature is that scum that collects and floats due to hydrogen gas, bubbling bubbles, etc. is easily forced out to the outside along an inclined plate installed up to the upper surface of the outlet with an elevation angle on the liquid surface.

[0007]

Next, examples of the electrolysis apparatus of the present invention will be described in detail.

FIG. 1 shows a scum and gas discharge tool in which a cathode and an anode are made of an aluminum alloy in a liquid tank, and an inclined plate for inclining the liquid surface reaching the scum discharge port is installed on the upper surfaces of both electrodes. It is a perspective sectional view showing the configuration of the electrolytic ion aggregating apparatus provided.

In FIG. 1, the liquid tank 1 has five surfaces welded by a vinyl chloride plate which is an insulator, seven aluminum alloy flat plates are installed, and the cathodes 2a and 2 are alternately arranged.
b, 2c, 2d and anodes 3a, 3b, 3c. The inclined plate 4 is installed above the scum discharge port 5 at an elevation angle, and the space 7 formed by the liquid surface 6 and the inclined plate 4 is minimized, so that the scum 8 floats above the liquid surface 6, as illustrated. It has the effect of minimizing the amount of hydrogen gas that is not present. The end surface 9 of the inclined plate 4 is sealed with the liquid tank 1 so that the upper portion 10 does not leak liquid.

To explain the principle of floating discharge in FIG. 2 in detail,
Positively charged multiply charged ions of aluminum (Al
3+) or polymer ion [Al 8 (OH) 4 + / 20] and also insoluble aluminum hydroxide is generated to neutralize the charge of the dispersed colloid component 11 and, at the same time, hydrogen gas generated from the polar surface. , Oxygen gas and bubbling equipment 12
As a large amount of air and carbon gas float from the above, they become scum 8 by flocking and agglomeration. The liquid level 6 is controlled by a liquid replenishing plug (not shown) so that the liquid mixed in the discharged scum 8 is not reduced.

[0011]

As described above, according to the present invention, in the process of charge neutralizing and aggregating the colloidal components in the industrial wastewater and the tap water by the metal ions in the electrolysis, the floating stir flow is caused to cause the agglomeration. Hydrogen gas, which is an effective means,
It has the practical benefit of being able to safely and reliably discharge extremely swelling hydroxides of metal salts, etc., without installing auxiliary equipment or devices.
