Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an electrolytic unit (K) in a continuous ionized water generator.

(Prior art) The electrolysis unit in this type of continuous ionized water generator is constructed with a cylindrical negative electrode as an outer wall, and a cylindrical partition wall and a positive electrode inside the negative electrode. A device is known in which a thin cylindrical cathode chamber and an anode chamber are formed, and the water is continuously electrolyzed while passing the water in the vertical direction.

In this case, the cathode also serves as the outer wall, simplifying the structure, and the partition wall is made of a porous material such as unglazed ceramic, which itself has appropriate strength and shape retention, so the anode Both are easy to attach and detach from the cathode,
No special structural considerations were required.

(Technical Problem) However, recently, a thin permeable diaphragm having pores as small as about 0.6 microns has been developed, and it has become possible to use this diaphragm for electropermeation. However, when such a material is used as a partition wall, it does not have strength and does not retain its shape. Moreover, when water is continuously electrolyzed, pressure resistance is required to pump water, so the diaphragm must be tightly stretched. Furthermore, it is necessary to increase the electrolytic strength by making the gap between the electrode and the diaphragm as narrow as possible, and it is also necessary to consider the design. Furthermore, during the electrolysis process, scale is deposited on the surface of the diaphragm facing the negative electrode, so it is necessary to take out the diaphragm and wash its surface from time to time, which can reduce the strength of the diaphragm. There are various disadvantages in that the diaphragm is made of a thin and non-shape-retentive membrane.

(Object of the Invention) The present invention has been made based on the above circumstances, and the anode is maintained by providing support structures at both ends of the anode, and tightening and fixing the diaphragm in a cylindrical shape between the support structures. In addition to being used as a shape and strength member, the diaphragm is used as the wall of the water passage, and by configuring the diaphragm as a unit with the positive electrode, it avoids structural complexity and has a pressure-resistant structure, making it easy to attach and detach for cleaning etc. The purpose of the present invention is to provide an electrolysis unit in a continuous type ionized water generating device that can perform the electrolysis and maintain the highest electrolytic strength.

(Technical configuration of the invention) For this purpose, the present invention comprises a cylindrical negative electrode as an outer wall, and arranges a partition wall and a positive electrode inside the negative electrode,
This forms a thin cylindrical cathode chamber and an anode chamber, and in a device that continuously electrolyzes water while passing water in the longitudinal direction, the anode has at least a peripheral surface that has a passage wall surface for water passage. The cathode has a structure having a circular cylindrical surface or a surface almost similar thereto, and has a structure in which water passes only between the surface and the inner surface of the cathode, and the cathode is provided with water passages at both ends. A partition wall support member is attached, and the partition wall is composed of a thin electrolytic diaphragm, and the upper and lower ends are fixed to the partition wall support member while being supported in a cylindrical shape between the partition wall support members. This is a characteristic feature.

(Example) Hereinafter, an example of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 denotes a cylindrical cathode made of stainless steel or the like, which constitutes the outer wall of the electrolysis unit. An upper end block 3 and a lower end block 4 are in contact with the upper and lower ends of the electrode 1 via a backing 2.2, and by passing a through bolt between the upper end block 3 and the lower end block 4 and tightening the nuts, the above cathode [
is clamped and fixed between the upper and lower end blocks 3.4. Further, inside the negative electrode 1, a positive electrode 5 made of ferrite and having a cylindrical surface or a surface almost similar to the cylindrical surface is disposed. A partition support member 7 having a water passage 6 is attached to both ends of the positive electrode 50 . A cylindrical partition wall 8 is coated over the support member 7.7, and both ends of the partition wall 80 are fixed to the support member 7.7 using nylon fishing line. As a result, the partition wall 8 is stretched vertically. In this case, the partition wall 8 is composed of a thin cylindrical electrolytic partition made of a material used for microfilters, etc., and has a space between it and the positive electrode 5 of, for example, approximately 1.
A cylindrical anode chamber 9 of about 1 mm in diameter is formed, and a cylindrical cathode chamber 10 of, for example, about 1 mm in diameter is formed between the cathode 1 and the rib 7 formed on the outer periphery of the support member 7.
a is in slidable contact with the inner wall of the negative electrode 1 to suppress the movement of the positive electrode 5 in the lateral direction. A rod-shaped lead 11 for applying a DC voltage is passed through the top of the positive electrode 5, and is in contact with the top of the positive electrode 5.
Among the supporting members 7, the lower supporting member 7 is applied with upward supporting elastic pressure by a compression coil spring 12, and the lower end block 4 is provided with the rib 7a.
A water supply chamber 13 is formed in which water is passed to the cathode chamber 10 through the space, and also to the anode chamber 9 through the water passage 6. An alkaline ionized water outlet chamber 14 receives the water, and an acidic water outlet chamber 15 receives water from the anode chamber 9 via the water passage 6.

In this embodiment, two sets of electrolytic units are interposed between each one of the upper end block 3 and the lower end block 4, and are configured to be used in parallel. Alternatively, it goes without saying that three or more sets of electrolytic units may be interposed.

In addition, in the figure, the reference numeral 16 is a conductive terminal for the negative electrode l;
7 is a conductive terminal for the positive electrode 5;

In such a configuration, water is supplied through the water supply chamber 13 while applying a DC voltage to both electrodes 1 and 5, and is supplied from the gap of the lip 7a to the cathode chamber lO and through the water passage 6 to the anode chamber 9. When flowing between the electrodes 1 and 5, alkaline water is generated in the cathode chamber 10 side and acidic water is generated in the anode chamber 9 side by electrolysis and electric osmosis through the partition wall 8. .15 for use.

And, the characteristic feature of this is that it has no strength itself,
The non-shape-retaining diaphragm 8 is formed into a unit on the outside of the positive electrode 5 and is held in tension, which allows it to maintain sufficient pressure resistance even in continuous electrolysis without losing its shape. When the cathode 1 is removed from the cathode 1, the scale deposited on the outer surface can be easily washed away. In addition, the positive electrode 5 has a structure in which at least the peripheral surface has a cylindrical surface that forms a passage wall surface for water passage, or a surface that is almost the same (in this embodiment, the positive electrode 5 has a cylindrical shape). However, it may be cylindrical or cylindrical or columnar with an elliptical cross section). Therefore, the distance between the electrodes can be shortened to the designed pole Ia, and therefore even at low voltage (because current leakage occurs through the water supply channel) (in the case of a continuous type, the voltage must be low), sufficient electrolytic strength can be ensured.

(Effects of the Invention) As described in detail above, the present invention can ensure shape retention and strength even if a thin electrolytic diaphragm is used for the partition wall, can achieve unitization, and even at low voltage. Since the electrode spacing can be made extremely small in terms of design, it is possible to obtain the effect that sufficient electrolytic strength can be ensured.
