Description

Technical Field

[0001] This utility model relates to the field of electrolytic hydrogen production technology, specifically to an electrode frame and electrolytic cell with small chamber voltage detection. Background Technology

[0002] An electrolyzer is a key piece of equipment used for producing hydrogen by electrolyzing water. It mainly consists of a tank body, anode, cathode, and diaphragm. The diaphragm separates the anode and cathode chambers to prevent the generated gases from mixing. When electricity is applied, the current triggers chemical reactions between the ions in the electrolyte at the electrodes. At the anode, anions in the solution lose electrons and undergo oxidation; at the cathode, cations in the solution gain electrons and undergo reduction, thus producing oxygen and hydrogen.

[0003] During the operation of an electrolyzer, the voltage in each electrolysis chamber is one of the important operating parameters. A relatively suitable voltage range can ensure the high efficiency and stability of the water electrolysis process, thereby producing hydrogen with relatively stable quality. When abnormalities are not detected in time, it is easy to cause unplanned shutdowns, increase production losses, and fail to reduce electrolysis power consumption and improve electrolysis efficiency in time. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an electrode frame and electrolytic cell with small chamber voltage detection, which can detect abnormalities in time, reduce production losses, reduce electrolysis power consumption, and improve electrolysis efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides an electrode frame with small cell voltage detection, including an electrode frame body. The electrode frame body is made of insulating material. A metal part is provided on one side of the electrode frame body. The middle part of the metal part is located inside the side of the electrode frame body. One end of the metal part extends into the inner side of the electrode frame body, and the other end of the metal part extends into the outer side of the electrode frame body and is connected to a wire.

[0006] Furthermore, the pole frame body and the metal part are integrally formed by injection molding.

[0007] Furthermore, sealing lines are provided on both sides of the pole frame body, a positioning and mounting step is provided in the middle of one side surface of the pole frame body, and flow channel holes are also provided on the pole frame body around the positioning and mounting step. The flow channel holes are located inside the sealing lines, and fixing through holes are also provided on the pole frame body outside the sealing lines.

[0008] Furthermore, one end of the metal part is provided with a first bending portion, which extends the end of the metal part from the inside of the side of the pole frame body to the surface of the positioning and mounting step portion.

[0009] Furthermore, the metal part has an annular hole in the middle, and the corresponding pole frame body has a through hole.

[0010] Furthermore, a second bending portion is provided on one end of the metal component located outside the pole frame body. The second bending portion extends the end of the metal component from the inside of the side of the pole frame body and fits it against the outer surface of the pole frame body.

[0011] Furthermore, a bending positioning groove is provided on the surface of the pole frame body corresponding to the second bending portion.

[0012] Furthermore, one end of the wire passes through a through hole and is bound to a metal part to form a ring structure.

[0013] An electrolytic cell includes the electrode frame described above.

[0014] The beneficial effects of this utility model are:

[0015] By installing a metal component inside the insulated electrode frame, with one end of the component connected to a wire and the other end connected to an electrode plate placed inside the electrode frame, the voltage in each chamber can be detected in real time during the operation of the electrolytic cell. This allows for timely detection and handling of abnormalities, effectively preventing unplanned downtime and significantly reducing production losses. Furthermore, timely handling can reduce electrolysis power consumption and improve electrolysis efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0024] Reference Figures 1 to 6 As shown, one embodiment of the electrode frame with small chamber voltage detection of this utility model includes an electrode frame body 1, which is made of insulating material. A metal part 2 is provided on one side of the electrode frame body. The middle part of the metal part is located inside the side of the electrode frame body. One end of the metal part extends to the inside of the electrode frame body, and the other end of the metal part extends to the outside of the electrode frame body and is connected to the wire 3.

[0025] In use, the electrode frame body is used as a component of the electrolytic cell chamber. The electrode frame body is non-conductive, while one end of the metal part extends into the electrode frame body, i.e., inside the chamber, and the other end extends out of the electrode frame body. Therefore, the metal part can conduct electricity between the inside and outside of the chamber. Thus, by leading out the wire and connecting it to the negative terminal of the chamber, the voltage in a single chamber can be detected online in real time. In other words, abnormalities can be detected in a timely manner during the operation of the electrolytic cell.

[0026] Specifically, the electrode frame body is made of PSU, a high-temperature resistant and high-strength special engineering plastic with high mechanical strength, electrical insulation properties, and a certain degree of chemical corrosion resistance. It also exhibits good thermal aging resistance, creep resistance, and dimensional stability. The metal parts are made of N6 alloy. The electrode frame body and metal parts are integrally molded through injection molding, eliminating the complex processing, welding, and nickel plating processes required for existing metal electrode frames. This saves time and effort, reduces costs, improves production efficiency, and effectively fixes the metal parts inside the electrode frame body. Furthermore, an annular hole 9 is provided in the center of the metal part, as shown in the reference diagram. Figure 2 As shown, the annular hole has a circular ring structure around its perimeter, forming a concave-convex shape with the rest of the metal part. After injection molding, it plays a good limiting role in the length direction of the metal part.

[0027] Both sides of the pole frame body are provided with sealing lines 4 to ensure the sealing between adjacent components. A positioning and mounting step 5 is provided in the middle of one side surface of the pole frame body for placing the pole plate. The pole frame body around the positioning and mounting step is also provided with flow channel holes 6, which are located inside the sealing lines. The flow channel holes are the existing layout and will not be described in detail. The pole frame body outside the sealing lines is also provided with fixing through holes 7 for easy assembly.

[0028] Preferably, the chamber voltage detection is achieved simply by the metal part abutting against the electrode plate. Generally, it is more suitable for the metal part to be positioned in the middle of the electrode frame body's thickness direction. Therefore, a first bending portion 8 is provided at one end of the metal part. This first bending portion extends the end of the metal part from the inside of the electrode frame body's side to the surface of the positioning and mounting step, thus satisfying contact with the electrode plate while ensuring the effective strength of the electrode frame body's side, preventing one side from being too thin and easily damaged. Furthermore, one end of the metal part protrudes from the inner hole of the electrode frame body. By bending the metal part towards the electrode plate, better contact and abutment with the electrode plate can be achieved. (Refer to...) Figure 3 As shown.

[0029] Based on the annular hole, a through hole 10 is provided on the pole frame body corresponding to the annular hole. The through hole and the annular hole cooperate to form a through-hole structure. At this time, one end of the wire can pass through the through hole and contact the metal part to form an annular structure. The wire connection and fixation are simple and the connection strength is high. In order to increase the contact area between the wire and the metal part, a second bend 11 is provided on the end of the metal part located outside the pole frame body. The second bend 11 extends the end of the metal part from the inside of the side of the pole frame body and fits against the outer surface of the pole frame body. After the wire is bound, the wire can form a large contact area with the second bend 11. Figure 4 and the picture to Figure 6 As shown. A bending positioning groove 12 is provided on the surface of the pole frame body corresponding to the second bending part. The bent part of the second bending part is placed in the bending positioning groove for effective positioning. The bending positioning groove can also limit the binding wire, thereby ensuring that the wire can always maintain effective contact with the metal part.

[0030] Since there are sealing lines on both sides of the pole frame body, and the sealing lines protrude from the surface of the pole frame body, the increased thickness after the wires are tied to the surface of the pole frame body is not affected.

[0031] This application also discloses an electrolytic cell, including the aforementioned several electrode frames. End plates 13 are provided at both ends of the several electrode frames along their axial direction. The end plates and electrode frames are clamped and fixed together by bolt assemblies 14. Electrode plates 15, diaphragms, anodes, cathodes, and other components are also provided on the sides of the electrode frames. These are all existing arrangement structures and will not be described in detail. This forms several small chambers. Each small chamber is led out through metal parts and wires for measuring the chamber voltage. Each small chamber is connected in series, while each small chamber is led out through metal parts to form a parallel measurement method. This allows for monitoring of the voltage of each small chamber. When an abnormality occurs, it can be investigated in time, greatly improving the electrolysis efficiency. Furthermore, it can quickly determine which small chamber the abnormality is in, allowing for targeted repair of the abnormality, resulting in high efficiency.

[0032] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
