[0002] Compared to traditional sewage treatment, current electrolytic sewage treatment is more efficient and can significantly increase the treatment capacity. The principle of electrolysis is to place an anode material at one end and a cathode material at the other end in the sewage and conduct electricity to electrocatalyze the sewage.

[0003] The current electrode group is composed of an anode group and a cathode group by welding a bottom plate and a conductive rod. The bottom plate welding is used to ensure that the anode and cathode materials do not touch each other to prevent short circuits. Although the electrode group can also be completed by welding, there are also the following shortcomings: First, the solution composition of the sewage is relatively turbid, resulting in the growth of calcium and magnesium dirt on the electrode material or some sand and stone particles stuck between the electrode materials as the electrolysis time increases during the electrolysis process, making it impossible for the electrode group to work normally. The electrode plates need to be cleaned regularly, but the plates are fixed by floor welding and cannot be disassembled. At the same time, because the resistance between the electrodes needs to be reduced, the spacing between the electrode plates is generally very narrow, resulting in the inability to efficiently treat the dirt on the electrode plates. Utility Model Content

[0004] To this end, the technical problem to be solved by the present invention is to overcome the problem in the prior art that the electrode plates are fixed by floor welding, which makes them impossible to disassemble.

Detailed Description of the Embodiments

[0027] The following further describes the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0028] Embodiment 1

[0029] Refer toFigures 1-6 As shown in the figure, a detachable electrode group of the present utility model includes:

[0030] An electrode assembly, which includes: a plurality of alternately arranged negative electrodes 4 and positive electrodes 3, and pole ears 2 extending from the ends of the negative electrodes 4 and positive electrodes 3 respectively;

[0031] A disassembly and assembly component, which includes: first through holes 9 respectively formed through each of the negative electrodes 4 and each of the positive electrodes 3, second through hole assemblies 10 respectively formed in the pole ears 2, a first threaded member 7 inserted through the first through holes 9, a second threaded assembly 5 inserted through the second through hole assemblies 10, the first threaded member 7 and the second threaded assembly 5 are respectively sleeved with a first sleeve body 6 and a second sleeve body 8, the first threaded member 7 and the first sleeve body 6 are insulators, the first sleeve body 6 is arranged between adjacent positive electrodes 3 and negative electrodes 4, the second threaded assembly 5 and / or the second sleeve body 8 is a conductor, and nuts 1 are respectively sleeved on both ends of the first threaded member 7 and the second threaded assembly 5.

[0032] For the detachable electrode group of the present utility model, a plurality of first through holes 9 are coaxially arranged, and the axes of the plurality of first through holes 9 are perpendicular to the plane where each negative electrode 4 and positive electrode 3 are located. The first threaded member 7 is sequentially inserted through the first through holes 9 of the positive electrode 3 and the negative electrode 4. The size of the first threaded member 7 and the first through hole 9 are adapted to limit the positive electrode 3 in the plane, that is, in the left - right and front - back directions. The positive electrode 3 and the negative electrode 4 are alternately arranged, that is, the electrodes adjacent to both sides of the negative electrode 4 are positive electrodes 3, and the electrodes adjacent to both sides of the positive electrode 3 are negative electrodes 4. The first sleeve body 6 is arranged between adjacent positive electrodes 3 and negative electrodes 4 to limit the positive electrode 3 and the negative electrode 4 axially, that is, in the up - down direction, and nuts 1 are arranged at both ends of the first threaded member 7 to tightly lock and fix the sleeve body and the electrode group together. The second threaded assembly 5 sequentially passes through the second through holes 10 on the pole ears 2 of the positive electrode 3 and the negative electrode 4. The second sleeve body 8 increases the support area between the pole ears 2 to fix the pole ears 2. When both the second threaded assembly 5 and the second sleeve body 8 are conductors, current can be conducted between the pole ears 2 through the second threaded assembly 5 and the second sleeve body 8; when only the second threaded assembly 5 is a conductor, current is conducted between the pole ears 2 through the second threaded assembly 5, realizing a detachable fixing method for the positive electrode 3 and the negative electrode 4.

[0033] The negative electrode 4 and the positive electrode 3 are electrode plates, and the negative electrode 4 and the positive electrode 3 plates respectively undertake different electrochemical functions. When current passes through the electrode group, a reduction reaction occurs on the negative electrode 4 plate, while an oxidation reaction occurs on the positive electrode 3 plate. The large-area design of the electrode plate is beneficial to increasing the contact area of the reaction, thereby improving the reaction rate and efficiency. At the same time, the good electrical conductivity of the electrode plate ensures the rapid transmission of electrons, further promoting the smooth progress of the electrochemical process. Loosen and remove the nuts 1 and the second sleeve body 8 at both ends of the second threaded assembly 5, and the electrode tab 2 is disconnected from the electrical connection. Loosen and remove the nuts 1 and the first sleeve body 6 at both ends of the first threaded member 7, and the negative electrode 4 plate and the positive electrode 3 plate can be removed.

[0034] The number of the negative electrodes 4 is odd and at least three, and the number of the positive electrodes 3 is even and one less than the number of the negative electrodes 4. There is an accommodation space between adjacent negative electrodes 4, and each positive electrode 3 is respectively accommodated in the accommodation space. The number of the negative electrodes 4 can be three, five, seven or more. The number of the positive electrodes 3 is even and one less than the number of the negative electrodes 4. For example, when the number of the negative electrodes 4 is three, the number of the positive electrodes 3 is two; when the number of the negative electrodes 4 is five, the number of the positive electrodes 3 is four, and so on. Since the number of the negative electrodes 4 is odd, an accommodation space will naturally form between adjacent negative electrodes 4. The size and shape of these accommodation spaces match the positive electrodes 3, so that each positive electrode 3 can be respectively accommodated in these accommodation spaces. Such a design enables the negative electrodes 4 and the positive electrodes 3 to be closely arranged in an interleaved manner, increasing the effective reaction area of the electrodes and improving the working efficiency of the electrode group.

[0035] The electrode tabs 2 of the negative electrode 4 and the positive electrode 3 are respectively arranged at both ends on the same side. Arranging them at both ends on the same side of the electrode makes the connection of the electrode tabs 2 more convenient and neater during the assembly and use of the electrode group, and they will not interfere with each other, and there will be no chaotic wire crossing situation.

[0036] The plane where each positive electrode 3 is located and the plane where each negative electrode 4 is located are parallel to each other, so that the current is evenly distributed between the electrode plates, improving the efficiency and uniformity of the electrochemical reaction. This makes the electric field distribution inside the electrode group more uniform, reducing the situation where the local electric field intensity is too high or too low.

[0037] The materials of the first sleeve body 6 and the first threaded member 7 are one or more of polytetrafluoroethylene, polymethyl methacrylate, polyvinyl chloride, polyurethane, and polycarbonate. In this embodiment, polytetrafluoroethylene is selected to manufacture the first sleeve body 6 and the first threaded member 7. Utilizing the good insulation performance and corrosion resistance of polytetrafluoroethylene to ensure good insulation and fixation in the electrode group, and polytetrafluoroethylene has high hardness and wear resistance, and can be applied to multiple disassembly and assembly operations.

[0038] The materials of the second sleeve body 8 and the second threaded member are one or more of titanium, stainless steel, conductive plastic, or conductive rubber. Stainless steel has good mechanical properties and electrical conductivity, and relatively low cost at the same time; conductive plastic has certain flexibility and processability; conductive rubber has good elasticity and electrical conductivity. In this embodiment, titanium is selected as the material of the second sleeve body 8 and the second threaded member, which has high strength, good corrosion resistance and electrical conductivity to meet the requirements for high strength and good electrical conductivity.

[0039] The first sleeve body 6 and the second sleeve body 8 are threaded members, and the internal threads of the first sleeve body 6 and the second sleeve body 8 are respectively adapted to the external threads of the first threaded member 7 and the second threaded member. The internal thread of the first sleeve body 6 is adapted to the external thread of the first threaded member 7, and the internal thread of the second sleeve body 8 is adapted to the external thread of the second threaded member. Screwing the first sleeve body 6 and the second sleeve body 8 onto the first threaded member 7 and the second threaded assembly 5 respectively can limit the cathode plate and the anode plate through the first sleeve body 6 and the second sleeve body 8 respectively, and control the distance between each cathode plate and anode plate through the up and down adjustment of the first sleeve body 6 and the second sleeve body 8.

[0040] Two first sleeve bodies 6 and second sleeve bodies 8 are arranged between each adjacent anode machine and cathode electrode 4. The two first sleeve bodies 6 and second sleeve bodies 8 can move away from or close to each other. When assembling the electrode group, after the cathode electrode 4 and the anode electrode 3 are placed alternately, the two first sleeve bodies 6 and second sleeve bodies 8 are respectively placed on both sides of the cathode electrode 4 or the anode electrode 3. When the position of the electrode needs to be adjusted, the two sleeve bodies are operated to move closer to each other, so as to clamp the electrode from both sides, realizing the adjustment and fixation of the electrode position.

[0041] Embodiment 2

[0042] This embodiment discloses a water treatment system, including a detachable electrode group as described in Embodiment 1.

[0043] A water treatment system disclosed in this embodiment can realize the efficient treatment of sewage by using the unique design of the detachable electrode group. During the water treatment process, the cathode electrodes 4 and anode electrodes 3 in the detachable electrode group are arranged alternately, and the pollutants in the water are decomposed and transformed through electrolysis. When the sewage enters the treatment system, the detachable electrode group starts to work, and the current passes through the anode electrode 3 and the cathode electrode 4, generating an oxidation-reduction reaction on the electrode surface, thereby decomposing the organic pollutants in the water into harmless substances.

[0044] When more dirt or impurities adhere to the electrode surface, the electrode group can be conveniently disassembled to clean and maintain the electrode, effectively solving the problem of dirt accumulation caused by the difficulty of disassembling the traditional electrode group and ensuring the long-term stable operation of the water treatment system.

[0045] The water treatment system can also adjust the parameters of the detachable electrode group according to the water quality and treatment requirements of the sewage, such as the electrode spacing, current density, etc., so as to achieve the best treatment effect. At the same time, the system is also equipped with a monitoring and control system, which can monitor various parameters in the water treatment process in real time, such as water quality indicators, current and voltage, etc., to ensure the safety and reliability of the treatment process.

[0046] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
