Description

Silver Colloidal Aqueous Solution Manufacturing Equipment {Colloidal Silver Generator}

The present invention relates to an apparatus for producing silver colloid aqueous solution which can be used as a drinking and natural fungicide. Specifically, the high-purity silver (silver) of 99.9% or more is electrolyzed in distilled or purified water, thereby uniformizing ionized silver. The present invention relates to a silver colloid aqueous solution manufacturing apparatus.

Since ancient times, the sterilization function of silver has been well known, and has recently attracted attention in terms of its antibiotic function. Records of the use of silver colloidal aqueous solutions began to appear in the late 1800s and are very frequent in the literature of the 1910-1920s. In 1910 Henry Crookes observed that B. coli communis died in 6 minutes in an aqueous silver colloid solution (Crookes, Henry, 1910, “The use of colloial of silver”, London, England). In 1920, Alfred B. Searle reviewed the above documents and published a book that, along with his own findings, that aqueous silver colloids were very useful for bactericidal killing (Searle, Albert B. , 1920, “The use of Colloids in health and disease”, Constable & Company LTD, London, England). Since the 1940s, the use of synthetic antibiotics by chemical preparations has been in full swing, and the use of silver colloidal aqueous solution having antibiotic properties has sharply decreased. In recent years, however, due to the abuse of synthetic antibiotics, the resistance of various bacteria to antibiotics has increased, and even VRSA (vancomycin-resistant Staphylococcus aureus) and SARS (Acute Respiratory Syndrome), which are not sterilized by any antibiotic, The development of new antibiotics has not been able to keep pace with the growth of resistant bacteria. Accordingly, there is a renewed interest in silver colloidal aqueous solutions that sterilize bacteria by a mechanism different from synthetic antibiotics.

Ph.D. in Microbiology, Brigham Young University, USA Prof. Ron W. Leavitt conducted a sterilization study of colloidal aqueous solutions through precise measurement and observation tools and confirmed that 16 single cell pathogens, including Escherichia coli, were sterilized at low concentrations below 5 PPM (Deseret News, Tuesday, May 16). , 2000). As described above, the silver colloidal aqueous solution has been proven to be very good sterilization and non-toxic to the human body, and is expected to be more anticipated as a natural antibiotic that can replace the antibiotic prepared by the chemical preparation method.

The structure of the conventional silver colloidal aqueous solution maker is configured to store two silver bars of the positive electrode and the negative electrode at regular intervals and store them in a container, or two plate-shaped silver electrodes facing each other and stored in a container. The electrode is immersed in pure water such as distilled water and then subjected to electrolysis to prepare a silver colloidal aqueous solution. FIG. 4 schematically shows the electric field distribution (electric force line) when a voltage is applied to the silver electrode of the conventional manufacturing machine. The electric field lines have the highest density of the electric field lines closest to the two electrodes, and the electric field lines have a smaller density when they are moved out of the proximity plane. Due to the non-uniformity of the electric field formed between the electrodes, ionization of the silver electrode occurs locally on the silver electrode, and as a result, not only silver ions (Ag +) but also silver particles having a relatively large size compared to the silver ions are generated, thereby providing the same concentration. Compared to the pure silver ion colloidal aqueous solution, the particle surface area was reduced, and there was a problem in that bactericidal properties and water absorption decreased during drinking.

In addition, in the case of the conventional counter-type plate electrodes described above, it is difficult to maintain the spacing between the plate electrodes in equilibrium, and due to the shape distortion caused by frequent washing of ductile silver, unevenness of the electric field occurs between the electrodes. As with the silver bars, there was a problem of ionizing so as to be locally deflected. In the case of the electrodes, as the silver particles dispersed in the water grow, silver crystals grow and precipitate in the cathode even at a low concentration of 3 ppm or less, which is contained in the silver colloidal aqueous solution, resulting in high concentration and high efficiency. There was a problem in preparing a clear colloidal solution.

In order to solve this problem, the present applicant has devised an application (utility model 0309759) to devise an elliptic cylindrical cathode which forms a uniform electric field. In the case of the above design, it was possible to produce a transparent colloidal solution up to a high concentration of 15 ppm or more with high efficiency. There was a problem.

Accordingly, an object of the present invention is to form a uniform electric field between an anode and a cathode in order to solve and improve the conventional problems described above, thereby performing silver ionization, thereby increasing the concentration of silver nanoparticles. The present invention provides a silver colloidal aqueous solution manufacturing apparatus capable of producing a silver colloidal aqueous solution containing.

In addition, by dispersing the silver particles ionized in the ionization process in an aqueous solution faster and more uniformly than the conventional manufacturing apparatus, the silver crystal growth can be suppressed to prepare a high concentration of transparent silver colloidal aqueous solution. The present invention provides an apparatus for preparing a silver colloidal solution, which is easy to maintain.

In order to achieve the above object, the present invention forms an S-shaped cathode (cathode) formed with a semi-cylindrical portion, and the silver electrode on the rod or tube in the center of the semi-cylindrical portion of the electrode and the inner peripheral surface of the semi-cylindrical portion; It is formed to be spaced apart in parallel to form a uniform electric field between the anode and the cathode when a voltage is applied.

According to the present invention, the equal spacing is maintained between the semi-cylindrical portions of the silver rod anode 10 and the S-shaped anode 20, and the two electrode bodies are immersed in distilled or purified water, followed by direct current. Alternatively, when a DC square wave voltage is applied, the outer circumferential surface of the positive electrode silver rod 10 is uniformly electrolyzed to a small amount, resulting in silver ions (Ag +), which are dispersed in distilled water to produce a high concentration of transparent silver colloidal aqueous solution. .

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

Figure 1 is a longitudinal cross-sectional view of one embodiment of a silver colloid aqueous solution manufacturing apparatus according to the present invention, Figure 2 is a bottom view of one embodiment of a silver colloid aqueous solution manufacturing apparatus according to the present invention. Figure 3 is a schematic diagram of the electric field distribution formed between the anode (10) and the cathode body (cathode) 20, the DC voltage is applied to the silver colloid aqueous solution manufacturing apparatus according to the present invention.

In the configuration of the apparatus of the embodiment, the PCB 31, which is configured with a power supply unit 32 that receives power from the outside and a control circuit unit 60 for controlling and displaying input and output, is accommodated and the silver electrode 10 is inserted and fixed. A main body 30 fixedly fixing the silver electrode rod fixing portion 11 and the S-shaped negative electrode body 20, a negative electrode body 20 having two semi-cylindrical portions formed in an S shape, perpendicularly to the lower end of the main body, and It is composed of two silver electrode rods 10 which are spaced apart from the inner circumferential surface of the semi-cylindrical portion at the center of the semi-cylindrical semi-cylindrical portion and inserted into the silver electrode fixing portion 11 of the main body 30.

As shown in FIG. 2, the inner circumferential portion of the cross section of the S-shaped negative electrode body 20 of the above embodiment has a semi-cylindrical cross-section, and the two silver electrode rods 10 fixing portions 11 are the S-shaped negative electrodes. It is located in the center of the sieve 20 and is built up in the main body. Therefore, the inner circumferential surface of the semi-cylindrical portion of the cathode body and the outer circumferential surface of the silver electrode rod 10 are spaced in parallel at equal intervals, and when a DC voltage is applied, the strength between the anode body 10 and the cathode body 20 as shown in FIG. A uniform electric field is formed in the form of radiation. Therefore, as the electrolysis proceeds, silver ions (Ag +) are uniformly generated on the surface of the silver electrode anode body 10, and ionized silver ions (Ag +) of the uniform particles are uniformly dispersed and moved in the form of radiation to form an electrolyte solution ( Dispersed in distilled water or purified water), it was possible to produce a transparent silver colloid aqueous solution up to a predetermined concentration (for example, 5 to 15 ppm) without precipitation of precipitates.

However, when a rod-shaped electrode is used for both the cathode body 51 and the anode body as in the related art, an electric field having a shape as shown in FIG. 4 is formed and a strong electric field on the surface closest to the outer peripheral surfaces of the two electrodes. This action causes the deflected abrasion in the silver rod anode body 51 which is dissolved into silver ions (Ag +), and the silver ions (Ag +) generated from the low concentration (for example, 3 ppm) at the initial stage of ionization are the most of the cathode body 52. It grows to the close contact surface and grows and precipitates as a silver crystal in the form of a branch from the outer circumferential surface of the silver rod cathode body 52 toward the anode body 51. As the ionization proceeds further, the growth of the silver crystal is accelerated so that the end of the silver crystal growth portion is accelerated to approach the anode 51 and finally connected to the anode 51. By energizing, electrolysis stops, and it becomes impossible to obtain the required silver ion (Ag +) concentration. In addition, it is difficult to obtain a transparent silver colloidal solution due to the formation of a precipitate by the silver crystal growth portion, and in order to avoid such a phenomenon, the two electrode rods of the anode 51 and cathode 52 are formed. Although the spacing is widened, the growth of silver crystals is inevitable, forming a precipitate, and the electrolysis time is drastically longer to reach a predetermined concentration.

5, the control block diagram of the silver colloid aqueous solution manufacturing apparatus of this invention is shown. The control circuit unit 60 includes an input unit 62 for instructing control start, a voltage adjusting unit 64 for generating and outputting a preset DC voltage applied to the positive electrode 10 and the negative electrode 20, and the direct current. Sensing control unit 65, the input unit 62, and the voltage adjusting unit 64 for detecting a change state of the output current as the ionization of silver proceeds by applying a voltage to the electrode bodies 10 and 20 and controlling the output current. And a microprocessor 63 which receives information from the detection control unit 65 and controls the process of preparing the silver colloidal solution and outputs the colloidal aqueous solution to the output display unit 67.

Figure 6 is a longitudinal cross-sectional view showing an embodiment of the silver colloid aqueous solution manufacturing apparatus according to the present invention. Distilled or purified water is put into a suitable glass or plastic container 70, and the integrated modular silver colloid aqueous solution manufacturing apparatus of FIG. 1 according to the present invention is immersed in distilled water, and then supplied from the adapter 80. When the ˜30 V DC power is connected to the external power supply terminal 32 and the start switch 35 is pressed, the control circuit 60 generates the S-shaped cathode body 20 and the two silver electrode anode bodies 10. A direct current or a square wave DC voltage is applied, and silver is ionized on the surfaces of the two electrode electrodes 10 and dispersed in distilled water so as to have a high concentration (eg, 5) without precipitation of silver crystal precipitates. A solution of silver colloid with a uniform and transparent particle size up to ˜15 ppm) is prepared.

The formation of the S-shaped electrode does not limit the present invention. For example, the circumferential angles of the semi-cylindrical portions of the S-shaped electrode body that maintain the same interval with the silver electrode are not limited to 180 degrees, and 150 degrees, 250 degrees, and the like. It is known that it can be modified freely. In addition, the number of silver electrode rods and the semi-cylindrical portion is not limited to two, but may be one, three, four, etc., depending on the amount of silver ion water to be prepared, and the arrangement of the semi-cylindrical portions may be modified in various forms. Can be said to be a fact known to those with common sense, which does not depart from the spirit of the present invention.

As described above, the present invention constitutes an S-shaped electrode body 20 in which a semi-cylindrical portion having an equal interval with an outer circumferential surface of the electrode body 10 in the form of a rod or a tube is formed, and thus the anode body 10 is prepared during the production of silver colloidal aqueous solution. By forming a uniform electric field between the electrode and the cathode body 20, it provides an effect of uniformly generating silver ions (Ag +) having a uniform particle size on the surface of the silver electrode body in which cation of silver proceeds. In addition, the ionized silver ions (Ag +) are uniformly dispersed throughout the aqueous solution through the open surface of the S-shaped electrode body 20, and the silver crystals up to a predetermined concentration (for example, 5 to 15 ppm) silver crystal) provides the effect of enabling the preparation of a transparent silver colloidal solution without precipitation of precipitates.
