Description

Technical Field

[0001] This invention belongs to the field of Faraday electrode technology, specifically a Faraday electrode that can be used for electrolysis of pure water. Background Technology

[0002] The Faraday electrolysis electrode structure consists of two platinum electrodes with a diameter of 0.5 mm and a spacing of approximately 0.5 mm. The electrodes and the electrode holder are on the same plane. Because pure water has very low conductivity (i.e., very high resistance) and extremely poor conductivity, conventional Faraday electrolysis electrodes cannot directly electrolyze pure water. Chemical substances (such as potassium hydroxide) need to be added to the solution to increase its conductivity before Faraday electrolysis can be performed. However, the addition of conductive chemical substances to pure water alters the composition of the solution being tested, thus polluting the water quality. Utility Model Content

[0003] The purpose of this invention is to provide a Faraday electrode that can be used for electrolysis of pure water, so as to solve the problems mentioned in the background art.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A Faraday electrode for electrolysis of pure water includes a cathode and an anode, both of which have a helical structure and are connected by a screw thread.

[0006] Preferably, the front end of the negative electrode is provided with a negative electrode head, the front end of the positive electrode is provided with a positive electrode head, both the negative electrode head and the positive electrode head pass through the fixed base, and both the negative electrode head and the positive electrode head are fixedly connected to the fixed base.

[0007] Preferably, the negative electrode and the positive electrode are fitted with a gap.

[0008] Preferably, the outer sides of the cathode and anode are provided with several limiting buckles for limiting and fixing the cathode and anode.

[0009] Preferably, the limiting buckle adopts a semi-circular structure with two symmetrical slots on its bottom surface, and the adjacent negative electrode and positive electrode are respectively locked in the two slots.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] In this invention, both electrodes are designed with a spiral structure and are screwed together, which increases the surface area of ​​the electrodes and reduces the distance between them, thereby reducing the resistance of the solution between the electrodes and improving the electrolysis efficiency. This makes it suitable for the electrolysis of pure water. At the same time, a limiting buckle is provided to fix the two connecting parts and stabilize the distance between them.

[0014] The specific embodiments of this utility model are described in detail below.

[0015] The "range" disclosed in this utility model is defined by a lower limit and an upper limit. A given range is defined by selecting a lower limit and an upper limit, which define the boundaries of a particular range. Ranges defined in this way can include or exclude endpoints and can be arbitrarily combined; that is, any lower limit can be combined with any upper limit to form a range. For example, if a range of 10–50 is listed for a specific parameter, it is also expected that ranges of 10–40 and 20–50 are also included. Furthermore, if the minimum range values ​​are listed as 1 and 2, and the maximum range values ​​are listed as 3, 4, and 5, then the following ranges are all expected: 1–3, 1–4, 1–5, 2–3, 2–4, and 2–5. In this application, unless otherwise stated, the numerical range "a–b" represents a shortened representation of any combination of real numbers between a and b, where a and b are real numbers. For example, the numerical range "0–5" means that all real numbers between "0–5" have been listed herein; "0–5" is merely a shortened representation of these numerical combinations.

For example, the mention that the method may also include step (c) indicates that step (c) may be added to the method in any order. For example, the method may include steps (a), (b), and (c), or it may include steps (a), (c), and (b), or it may include steps (c), (a), and (b), etc.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example:

[0026] A Faraday electrode that can be used for electrolysis of pure water, such as Figure 1 As shown, it includes a negative electrode 2 and a positive electrode 3. Both the negative electrode 2 and the positive electrode 3 adopt a spiral structure, and the negative electrode 2 and the positive electrode 3 are connected by a screw.

[0027] In one possible implementation, the front end of the negative electrode 2 is provided with a negative electrode head 21, and the front end of the positive electrode 3 is provided with a positive electrode head 31. Both the negative electrode head 21 and the positive electrode head 31 pass through the fixed base 1, and both the negative electrode head 21 and the positive electrode head 31 are fixedly connected to the fixed base 1.

[0028] In one possible implementation, the negative electrode 2 and the positive electrode 3 are fitted with a gap.

[0029] In one possible implementation, several limiting buckles 4 are provided on the outer sides of the negative electrode 2 and the positive electrode 3 for limiting and fixing the negative electrode 2 and the positive electrode 3.

[0030] In one possible implementation, the limiting buckle 4 adopts a semi-circular structure with two symmetrical slots on its bottom surface, and the adjacent negative electrode 2 and positive electrode 3 are respectively locked in the two slots.

[0031] In one possible implementation, both the negative electrode 2 and the positive electrode 3 are connected to the slot by an interference fit.

[0032] In one possible implementation, both the negative electrode 2 and the positive electrode 3 are made of platinum alloy, with an electrode diameter of 0.5 mm, an electrode spacing of 0.2 mm, and an electrode extension from the electrode holder of 25 mm. Under the condition of the same electrode diameter, a longer electrode length results in a larger electrode surface area, a smaller equivalent resistance between the electrodes, and better conductivity; conversely, a smaller electrode spacing results in a smaller equivalent resistance between the electrodes and better conductivity.

[0033] By adopting the above technical solution:

[0034] The resistance between electrodes is inversely proportional to the surface area of ​​the electrodes and directly proportional to the distance between the Faraday electrodes. By increasing the surface area of ​​the Faraday electrodes and decreasing the distance between them, the resistance between the solutions can be reduced by physical methods. The lower the resistance between the solutions, the better the conductivity and the higher the electrolysis efficiency.

[0035] Pure platinum has relatively low hardness and is easily deformed; electrode materials are made by adding other metals to pure platinum to increase the hardness of the electrode, prevent electrode deformation from changing the electrode spacing, and avoid affecting the consistency of the electrodes.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
