Description

Technical Field

[0001] The present invention relates to the field of electrolysis technology, and in particular to a high-efficiency and stable electrolytic cell structure. Background Art

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode, with a diaphragm separating the anode and cathode compartments. Depending on the electrolyte, they are classified into three categories: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, producing the desired product.

[0003] Electrolyzers require electrodes made of specialized materials, such as metal oxides and diamond-coated electrodes. These specialized electrodes are used in fields like environmental protection and the chemical industry. When used in environmental protection, primarily for wastewater treatment, the electrodes are typically larger, minimizing potential issues like conductivity, area utilization, current density, and heat dissipation.

[0004] Currently, electrolyzers for producing ozone water mostly use metal electrodes or BDD (boron-doped diamond) electrodes, with an ion membrane or proton exchange membrane between them. When the electrodes are based on an inert metal substrate, simple electronic soldering is difficult because the inert metal cannot be soldered with ordinary solder. Specialized welding processes are required to weld the inert metal substrate to a readily solderable metal before electrical connection, which is demanding and expensive. BDD electrodes, on the other hand, are based on a non-conductive silicon substrate and require a coating to provide conductivity. They also need to be in close contact with the ion membrane to function effectively during the electrolysis process, requiring an external housing to secure them. BDD electrodes are physically brittle, making them difficult to clamp using hard plastic. Furthermore, since sheet-like objects are difficult to make completely flat, a housing is even more crucial. These housings are typically made of soft materials such as silicone or rubber, which are affected by ozone, impacting performance and lifespan. Therefore, these shortcomings need to be addressed in electrolyzers that produce ozone water.

[0005] Therefore, it is necessary to provide an efficient and stable electrolytic cell structure to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and examples. The embodiments of the present invention include but are not limited to the following examples.

[0018] Example 1: like Figure 1-4As shown, the efficient and stable electrolytic cell structure provided by the present invention comprises: a plastic shell 1, on which a water inlet pipe 2 and a water outlet pipe 3 are installed. Figure 1 The middle arrow indicates the direction of water flow. Water flows from the water inlet pipe 2 into the housing 1 and then flows out from the water outlet pipe 3, thereby forming a water flow channel. An electrolysis mechanism 4 is provided in the housing 1. The electrolysis mechanism 4 is provided in the middle part of the water flow channel, specifically in the middle of the housing 1. The electrolysis mechanism 4 includes a first electrode 41, a second electrode 42 and a diaphragm 43 between the first electrode 41 and the second electrode 42. Air holes are provided on the first electrode 41 and the second electrode 42, and the two are connected to the positive and negative poles respectively. When the first electrode 41 and the second electrode 42 are energized, the water flowing through can be electrolyzed to produce ozone water. The first electrode 41 and the second electrode 42 are connected to the housing 1 through a fixing component. The fixing component includes a metal cover plate 8 installed on one side of the housing 1. Two copper pillars 7 are installed on the metal cover plate 8. One of the copper pillars 7 A titanium column 6 is installed on the side plug, and one end of the titanium column 6 is tightly pressed on the adjacent first electrode 41 or second electrode 42. A threaded groove 9 is provided on the shell 1, and a wiring screw 10 is installed in the middle of the metal cover 8. The wiring screw 10 is screwed into the threaded groove 9. When in use, the positive and negative poles of the external wiring are respectively connected to the two wiring screws 10, and the wiring screws 10 are tightened to compress the wire, and the metal cover 8 is moved closer to the center of the shell 1, so that the copper column 7 drives the titanium column 6 to further press the first electrode 41 or the second electrode 42, so that the external wiring is tightly connected to the electrodes (first electrode 41, second electrode 42), ensuring the electrical stability of the first electrode 41 and the second electrode 42. Under the tight pressure of the metal cover 8 on both sides, the first electrode 41 and the second electrode 42 are moved closer to each other, and the diaphragm 43 between the two is compressed. This structure does not require the use of welding or other methods to connect the electrodes to electricity, which solves the disadvantage that electrodes made of special materials (the first electrode 41 and the second electrode 42 are inert materials) cannot be quickly connected to electricity. In addition, the structure is simple, stable, and low-cost. The fixing parts (titanium pillars 6) that come into contact with ozone are made of corrosion-resistant materials, so they have a long service life and can greatly improve the performance and life of the electrolytic cell structure.

[0019] By providing a plastic shell 1, a water inlet pipe 2 and a water outlet pipe 3, and using a connecting screw 10 to fasten the metal cover 8, the copper column 7 presses the titanium column 6 against the electrode, and the first electrode 41 and the second electrode 42 are fixed to the middle of the shell 1, so that the first electrode 41 and the second electrode 42 clamp the diaphragm 43 therebetween. The electrode fixing method of the electrolytic cell structure is simple and stable, and the inert metal electrode can be connected to the power supply without the need for welding. It is low in cost, resistant to oxidation, and suitable for popularization and use.

[0020] Example 2: like Figure 2As shown, the water outlet pipe 3 and the shell 1 are integrally formed, the water inlet pipe 2 is connected to the shell 1 with bolts, and a second sealing ring 15 is installed between the two. The second sealing ring 15 is embedded in one side of the shell 1. The connection between the shell 1 and the water inlet pipe 2 is sealed by the second sealing ring 15 to prevent water leakage. After removing the water inlet pipe 2, a tool can be used to pass through the water outlet pipe 3 and push the electrolysis mechanism 4 out from the other side of the shell 1. During installation, the order is reversed, which makes it convenient to replace the electrolysis mechanism 4.

[0021] By providing a detachable water outlet pipe 2, the electrolysis mechanism 4 can be easily installed and disassembled. The second sealing ring 15 is used to seal the connection between the shell 1 and the water inlet pipe 2, so that the electrolytic cell has better sealing performance and prevents leakage.

[0022] Example 3: like Figure 2 As shown, a countersunk hole 5 is provided on the shell 1, and the countersunk hole 5 is connected to the inner cavity of the shell 1. A titanium column 6 is inserted into the countersunk hole 5, and one end thereof is pressed against the electrode (the first electrode 41 or the second electrode 42). A first sealing ring 14 is sleeved on the titanium column 6. The first sealing ring 14 effectively seals the gap between the titanium column 6 and the countersunk hole 5 to prevent the ozone water inside the shell 1 from leaking to the outside through the countersunk hole 5.

[0023] By providing the countersunk hole 5 and the first sealing ring 14, the installation of the titanium column 6 can be facilitated, and the gap between the titanium column 6 and the countersunk hole 5 can be effectively sealed, so that the electrolytic cell has better sealing performance and prevents leakage.

[0024] Example 4: like Figure 2 As shown, a sealing plate 12 is installed between the metal cover 8 and the housing 1, and the binding screws 10 and the copper column 7 pass through the sealing plate 12. After tightening the binding screws 10, the metal cover 8 is pressed tightly against the sealing plate 12, and the sealing plate 12 is pressed tightly against the surface of the housing 1, thereby performing a secondary seal on the outer opening of the countersunk hole 5. Even if ozone water leaks into the countersunk hole 5, it cannot flow out of the countersunk hole 5 to the outside.

[0025] By installing a sealing plate 12 between the metal cover plate 8 and the housing 1, the countersunk hole 5 is sealed for a second time, and the electrolytic cell has better sealing performance and is safer to use.

[0026] Example 5: like Figure 2 As shown, the sealing plate 12 is provided with two positioning posts 13 and the housing 1 is provided with two positioning grooves 16 . During installation, the positioning posts 13 of the sealing plate 12 are aligned with the positioning grooves 16 and inserted, so that the sealing plate 12 can be quickly installed on the housing 1 .

[0027] The positioning column 13 and the positioning groove 16 can play a positioning role and facilitate the rapid installation of the sealing plate 12.

[0028] Example 6: like Figure 2 As shown, a spring 11 is sleeved on the copper column 7. The spring 11 is located between the titanium column 6 and the sealing plate 12, and the spring 11 is in a compressed state. At the contact portion between the titanium column 6 and the copper column 7, due to long-term use, atomic migration makes the two easily connected together. Therefore, by compressing the spring 11, the elastic force of the spring 11 is utilized to make it easier to separate the titanium column 6 and the copper column 7.

[0029] By arranging the spring 11 on the copper column 7 and utilizing the elastic force of the spring 11 , the titanium column 6 and the copper column 7 can be more easily separated, thereby facilitating the removal of the copper column 7 .

[0030] Example 7: like Figure 2 and Figure 4 As shown, the titanium column 6 includes an integrally formed plug 61 and a plug-in portion 62. A groove 63 is provided on the plug-in portion 62. The end of the copper column 7 is inserted into the groove 63 so that the copper column 7 and the titanium column 6 are plugged together. The end of the plug 61 is tightly pressed against the electrode (the first electrode 41 or the second electrode 42), and the first sealing ring 14 is sleeved on the plug 61, and the first sealing ring 14 is tightly attached to one side of the plug-in portion 62.

[0031] By providing the titanium column 6 including the plug 61 , the plug portion 62 and the groove 63 , the titanium column 6 is made to have a boss structure as a whole, which facilitates the installation of the first sealing ring 14 and the connection between the copper column 7 and the titanium column 6 .

[0032] Working principle: When in use, the positive and negative poles of the external wiring are connected to the two wiring screws 10 respectively. The wiring screws 10 are tightened to compress the wires, and the metal cover 8 is moved closer to the center of the housing 1. Then, the copper column 7 drives the titanium column 6 to further compress the first electrode 41 or the second electrode 42, so that the external wiring and the electrodes (first electrode 41, second electrode 42) are tightly connected to ensure the electrical stability of the first electrode 41 and the second electrode 42. Under the tight pressure of the metal cover 8 on both sides, the first electrode 41 and the second electrode 42 are moved closer to each other. The diaphragm 43 between the two is compressed, and the positive and negative poles of the external power supply are crimped to the two electrodes through the wiring screws 10, the metal cover 8, the copper column 7 and the titanium column 6, so that the first electrode 41 and the second electrode 42 are energized. This structure does not require the use of welding or other methods to connect the electrodes to electricity, which solves the disadvantage that electrodes made of special materials cannot be quickly connected to electricity. In addition, the structure is simple, stable and low-cost. The fixing parts (titanium column 6) in contact with ozone are made of corrosion-resistant materials, so it has a long service life and can greatly improve the performance and life of the electrolytic cell structure.
