Description

Technical Field

[0001] This utility model belongs to the field of electrode plate technology, and more specifically, it relates to a cathode and anode plate. Background Technology

[0002] In fields such as electrolytic chlorination, industrial wastewater treatment, and metal electrolysis, anode and cathode plates, as core conductive and reaction components, must operate under harsh conditions of strong corrosion and high current for extended periods. Their corrosion resistance and structural stability directly determine the operating efficiency and maintenance costs of the equipment. However, traditional anode and cathode plates are mostly constructed by directly processing a single metal sheet, relying on the material properties of the substrate itself to resist corrosion and withstand stress. This results in the main plate being directly exposed to the electrolyte during use, causing it to be continuously eroded by corrosive ions such as chloride and hydrogen ions in the electrolyte. This significantly weakens the conductivity and structural strength of the plate, ultimately leading to a decrease in electrolysis efficiency and a reduction in service life. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a cathode and anode plate to solve the technical problem in the prior art where traditional cathode and anode plates use a single metal plate and rely solely on the substrate to resist corrosion stress, resulting in the plate being exposed to corrosion, weakening performance, and reducing electrolysis efficiency and lifespan.

[0004] The purpose and function of this utility model's anode and cathode plate are achieved by the following specific technical means:

[0005] A cathode and anode plate includes a main plate and a connecting crossbar. The main plate is provided with a functional part and a connecting part. The connecting part is located above the functional part. The connecting crossbar is located above the main plate. The main plate is connected to the connecting crossbar through the connecting part.

[0006] Both sides of the main body plate are provided with a metal coating;

[0007] A through groove is provided on the main body plate, and the through groove spans the connecting part and the functional part of the main body plate;

[0008] A connector is provided at one end of the connecting crossbar.

[0009] According to a preferred embodiment, the length of the connecting crossbar is greater than the length of the main body plate, and the longitudinal and transverse axes of both the connecting crossbar and the main body plate coincide.

[0010] The portions of the connecting crossbar extending beyond the main body plate are configured as locking parts. The anode and cathode plates are locked onto the electrolytic cell by two sets of locking parts, and the connector is located on one set of locking parts.

[0011] According to a preferred embodiment, both sides of the main body plate are welded to the connecting crossbar using a welding machine.

[0012] According to a preferred embodiment, the main body plate is a titanium chloride plate, the main body plate has a length of 500mm to 1500mm, a height of 480mm to 1200mm, and a thickness of 2mm;

[0013] The connecting crossbar is a titanium-clad copper strip, with a length of 900mm to 1900mm, a height of 43mm, and a width of 13mm.

[0014] According to a preferred embodiment, the through groove is located at the center of the length of the main body plate;

[0015] The through groove has a width of 3mm to 15mm and a length of 50mm to 150mm, and penetrates through the main body plate.

[0016] According to a preferred embodiment, the connector includes a connector head, the cross-sectional area of ​​which is equal to the cross-sectional area of ​​the connecting crossbar, and the connector head is arranged laterally relative to the cross-section of the connecting crossbar.

[0017] The center point of the connector coincides with the center point of the cross section of the connecting crossbar, and the two are perpendicularly distributed in a cross structure.

[0018] One side of the connector is connected to one end of the connecting crossbar by a connecting plate, which is twisted.

[0019] According to a preferred embodiment, the connector has a 12mm diameter through hole at its center.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This anode and cathode plate features a metal coating on both sides of the main plate. This coating directly isolates corrosive media from the substrate, preventing surface pitting and oxidation peeling due to corrosion. This ensures the stability of the main plate's conductivity and structural strength, preventing a decrease in electrolytic efficiency. Furthermore, the main plate is made of titanium chloride plate, which possesses excellent resistance to electrolytic corrosion. Combined with titanium-clad copper connecting crossbars, this further enhances the overall structure's corrosion resistance and stress resistance. Compared to traditional single-metal plate structures, this significantly reduces the lifespan shortening caused by insufficient material protection, extending the overall service life of the anode and cathode plate.

[0022] 2. The design of dividing the main plate into functional and connecting sections avoids wasting coating in non-functional areas and reduces interference from the connecting structure to the reaction area, thus improving electrolytic reaction efficiency. The locking design at both ends of the connecting crossbar, combined with the cross-shaped connector and the twisted connecting plate, not only achieves stable mounting of the anode and cathode plates on the electrolytic cell, but also buffers stress during installation and use through the structural characteristics of the connecting plate, preventing loosening of the connection due to stress concentration. In addition, the through-slots running through the main plate can assist the flow of electrolyte, avoiding local electrolyte accumulation that aggravates corrosion, further ensuring the reaction stability of the main plate's functional sections. The overall structural design improves the performance of the anode and cathode plates from multiple dimensions, including protection, installation, and reaction efficiency.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0029] Example:

[0030] like Figures 1 to 3 As shown, this utility model provides an anode and cathode plate. The overall structure of the plate is built around the core requirements of conductive transmission and electrochemical reaction. The core components include a main plate 1 and a connecting crossbar 2, which work together to achieve stable conductivity and reaction functions. The main plate 1, as the main carrier of the electrochemical reaction, is divided into a functional section and a connecting section. The connecting section is located above the functional section and is mainly used to establish a connection with the connecting crossbar 2. The functional section is the core area where the electrochemical reaction occurs, ensuring a concentrated and efficient reaction process. The connecting crossbar 2 is positioned above the main plate 1, and the main plate 1 is fixedly connected to the connecting crossbar 2 through its connecting section. This connection method can evenly conduct the current transmitted by the connecting crossbar 2 to the functional section of the main plate 1, providing stable current support for the electrochemical reaction.

[0031] To address the issue of corrosion in traditional anode and cathode plates due to direct exposure of the substrate, a metal coating is applied to both sides of the main plate 1. The presence of the metal coating directly isolates the corrosive ions in the electrolyte from contact with the substrate of the main plate 1, preventing the substrate of the main plate 1 from being continuously eroded by corrosive ions such as chloride ions and hydrogen ions due to long-term exposure to the electrolyte, thus avoiding surface pitting, oxidation and peeling. This ensures that the conductivity and structural strength of the main plate 1 are not weakened.

[0032] A through-slot 3 is also provided on the main body plate 1. The through-slot 3 spans the connecting part and the functional part of the main body plate 1, and is located at the center of the length direction of the main body plate 1. This positioning ensures that the through-slot 3 is evenly distributed on the main body plate 1, and will not affect the overall stability of the main body plate 1 due to local structural imbalance. The width of the through-slot 3 is set to be 3mm to 15mm, and the length is set to be 50mm to 150mm. It runs through the main body plate 1. This size design allows the through-slot 3 to effectively assist the flow of electrolyte on the surface of the main body plate 1 without affecting the structural strength of the main body plate 1. During the electrolysis process, the electrolyte can flow through the through-slot 3 to avoid local accumulation of electrolyte on the surface of the functional part of the main body plate 1. This reduces the impact of excessively high or low local electrolyte concentration on the electrochemical reaction efficiency, and also reduces the risk of local corrosion of the main body plate 1 caused by local electrolyte retention.

[0033] The connecting crossbar 2, as a key component for current transmission, is longer than the main plate 1. Furthermore, the longitudinal and transverse axes of the connecting crossbar 2 and the main plate 1 coincide. This dimensional and positional fit ensures uniform current transmission from the connecting crossbar 2 to the main plate 1, preventing localized overheating or reduced reaction efficiency due to uneven current distribution. The portions of the connecting crossbar 2 extending beyond the main plate 1 are designed as locking parts. During actual installation, the anode and cathode plates are directly secured to the electrolytic cell via two sets of locking parts. The structure of these locking parts provides stable installation support for the anode and cathode plates, preventing displacement due to electrolyte scouring or equipment vibration during electrolysis. Simultaneously, connectors are located on one set of locking parts, further strengthening the connection between the anode and cathode plates and related components of the electrolytic cell, thus improving overall installation stability.

[0034] To ensure the robust connection between the main plate 1 and the connecting crossbar 2, both sides of the main plate 1 are welded to the connecting crossbar 2 using a welding machine. This welding connection effectively enhances the structural strength of the connection point, preventing loosening due to current surges or stress during long-term use. This reduces problems such as increased contact resistance and localized overheating caused by loose connections. Regarding material selection, the main plate 1 uses titanium chloride plate. Titanium chloride plate possesses excellent resistance to electrolytic corrosion and good electrical conductivity, enabling it to withstand the harsh conditions of the electrolysis process. Its specific dimensions are: length 500mm to 1500mm, height 480mm to 1200mm, and thickness 2mm. These dimensions meet the electrode area requirements of most electrolysis equipment while controlling the overall weight to ensure structural strength. The connecting crossbar 2 is made of titanium-clad copper strip. The titanium-clad copper strip combines the corrosion resistance of titanium with the high conductivity of copper, which can achieve efficient current transmission while ensuring its own resistance to electrolytic corrosion. Its dimensions are set to a length of 900mm to 1900mm, a height of 43mm, and a width of 13mm. The length can meet the setting requirements of the clamping parts at both ends, while the height and width can ensure the structural stability of the connecting crossbar 2 itself while ensuring the efficiency of current transmission.

[0035] The connector, as the core structure connecting the connecting crossbar 2 to external components, consists of a connector head 4. The cross-sectional area of ​​the connector head 4 is equal to that of the connecting crossbar 2. This dimensional matching ensures smooth current transmission between the connector head 4 and the connecting crossbar 2, avoiding current obstruction due to differences in cross-sectional area. The connector head 4 is arranged laterally relative to the cross-section of the connecting crossbar 2, and the center point of the connector head 4 coincides with the center point of the cross-section of the connecting crossbar 2. The two are vertically distributed in a cross structure. This structure increases the contact area between the connector head 4 and the external components, improves connection stability, and also makes the force on the connection part more balanced, reducing local stress concentration. One side of the connector head 4 is connected to one end of the connecting crossbar 2 by a connecting plate 5. The connecting plate 5 is twisted. This twisted structure gives the connecting plate 5 a certain deformation buffering capacity when subjected to force. During installation or use, when the connector head 4 or the connecting crossbar 2 is subjected to external force, the connecting plate 5 can absorb part of the stress through its own twisting deformation, preventing stress from being directly transmitted to the connection part and causing loosening of the connection or structural damage.

[0036] A 12mm diameter through hole 6 is provided in the center of the connector 4. The through hole 6 is mainly used to insert connecting bolts or other fasteners. Through the cooperation of the through hole 6 and external fasteners, the connector 4 can be tightly fixed to the related components of the electrolytic cell, further improving the overall stability of the anode and cathode plates.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
