Description

Technical Field

[0001] This utility model belongs to the field of electrolytic cell technology, specifically relating to an adjustable anode plate structure. Background Technology

[0002] The anode plate of an electrolytic cell is one of the core electrode components in the electrolysis process, playing a crucial role in conducting current and initiating oxidation reactions. Its performance directly affects electrolysis efficiency, product quality, and production energy consumption. In industrial applications, electrolysis is widely used in the chlor-alkali industry (electrolysis of brine to produce chlorine and sodium hydroxide), non-ferrous metal smelting (electrolytic refining of copper, zinc, and nickel or extraction of aluminum), electroplating (providing metal ions or conducting current), environmental protection (electrolytic treatment of wastewater and degradation of pollutants), and energy (electrolysis of water to produce hydrogen, lead-acid batteries, etc.). Therefore, the structure and fixing method of the anode plate have a significant impact on the stability and efficiency of the electrolysis unit.

[0003] Existing anode plates are typically plate-shaped or mesh-shaped structures connected to the positive terminal of the power supply. Their surface must possess good conductivity and chemical stability; in some applications, a precious metal coating is applied to enhance performance. As a common form, mesh anode plates offer several advantages: firstly, they increase the specific surface area, providing more active sites for the electrolytic reaction, thereby improving the uniformity of current density distribution, accelerating the reaction rate, and increasing electrolysis efficiency; secondly, they optimize mass transfer and drainage, allowing the electrolyte and products to flow smoothly, reducing side reactions caused by accumulation, and ensuring a stable electrolysis process.

[0004] However, while current mesh anode plates increase the specific surface area during the stamping and perforation process to create a hollow structure, the edges of the holes are often removed or ignored, resulting in a limited actual increase in area. This means the specific surface area is still insufficient to meet the requirements of high-efficiency electrolysis, leading to uneven current density distribution and limitations on electrolysis rate and reaction efficiency. Furthermore, traditional anode plates commonly use bolts to directly fix the conductive head. Once the installation position is determined, this structure is difficult to adjust, hindering flexible adjustment of the current distribution under different operating conditions. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an adjustable anode plate structure that can solve the above-mentioned deficiencies.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable anode plate structure includes a plate body and a conductive head. The plate body has uniformly punched perforations inside, and a perforated folded edge plate is punched on one side of the plate body corresponding to the position of the perforations. The perforated folded edge plate and the plate body are an integral structure. The perforated folded edge plate is used to increase the specific surface area of ​​the plate body, and the perforations are used for the flow of electrolyte and products.

[0008] Furthermore, an adjustment window is provided at the top of the plate, and a hook end is provided at the bottom of the conductive head, and the conductive head is hooked and installed inside the adjustment window through the hook end.

[0009] Furthermore, a support baffle is provided on one side of the conductive head, and the support baffle has a threaded hole inside.

[0010] Furthermore, a compression screw passes through the interior of the threaded hole, and the compression screw and the threaded hole are connected by threaded engagement.

[0011] Furthermore, a trapezoidal extrusion head is movably nested at the bottom of the extrusion screw, and a screw limiting groove is provided at the top of the trapezoidal extrusion head, which is nested at the bottom of the extrusion screw through the screw limiting groove.

[0012] Furthermore, the bottom surface of the trapezoidal extrusion head is inclined, and the bottom inclined surface of the trapezoidal extrusion head is in close contact with the top of the extrusion plate.

[0013] Furthermore, reinforcing ribs are provided at both ends of the support baffle and between the conductive head.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By punching perforations into the plate and retaining the perforated edge plate, the specific surface area of ​​the plate is significantly increased. Compared with the existing technology that removes the edge, this structure not only provides more active sites for electrolytic reactions but also enables the current density to be evenly distributed on the plate surface, thereby accelerating the electrolytic reaction rate and improving electrolysis efficiency. This effectively solves the problems of insufficient specific surface area and uneven current distribution in existing anode plates.

[0016] By setting an adjustment window at the top of the plate and a hook end at the bottom of the conductive head, the conductive head can be quickly hooked into the adjustment window. This, combined with the support baffle, threaded hole, clamping screw, and trapezoidal clamping head, achieves a tight fixation. This structure avoids the inconvenience of traditional bolt-through fixing methods, allowing the conductive head to be flexibly adjusted in different positions. It optimizes the current conduction path according to operating conditions, improving the applicability and ease of operation of the device, thus solving the shortcomings of existing anode plate conductive heads that are not adjustable and have poor practicality.

[0017] By combining the extrusion screws with the trapezoidal extrusion head, the fixation reliability between the conductive head and the plate is further enhanced based on the hook-and-loop installation. The beveled surface of the trapezoidal extrusion head can evenly distribute pressure, avoid local stress concentration, and improve the stability of the anode plate during long-term electrolytic operation.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] Example 1:

[0028] like Figure 1 and Figure 2As shown, an adjustable anode plate structure includes a plate body 101 and a conductive head 103. The plate body 101 has uniformly punched perforated holes 111 inside, and a perforated folded edge plate 112 is punched on one side of the plate body 101 corresponding to the position of the perforated holes 111. The perforated folded edge plate 112 and the plate body 101 are an integral structure. The perforated folded edge plate 112 is used to increase the specific surface area of ​​the plate body 101, so that the electrolyte can form more contact interfaces with the plate body 101, improve the uniformity of current density distribution, and thus improve the electrolysis rate and reaction efficiency. The perforated holes 111 are used for the flow of electrolyte and products, avoiding uneven current conduction caused by the accumulation of by-products during the reaction process, thereby ensuring the stability of the electrolysis process.

[0029] like Figure 1 , Figures 3-6 As shown, the top of the plate 101 is provided with an adjustment window 102, which is a rectangular opening structure, facilitating the flexible installation of the conductive head 103 by adjusting its position. The bottom of the conductive head 103 is provided with a hook end 132, which is bent downwards and can be reliably inserted into the interior of the adjustment window 102 to form a stable contact with the plate 101. The conductive head 103 is hooked and installed inside the adjustment window 102 by the hook end 132, avoiding the inconvenience of installation and the inability to adjust the position caused by the traditional anode plate fixing method with bolts. This allows the conductive head 103 to be flexibly adjusted in the installation position according to the needs of electrolysis conditions, improving the adaptability and practicality of the structure.

[0030] like Figure 1 , Figures 3-6 As shown, a support baffle 131 is provided on one side of the conductive head 103. The support baffle 131 and the conductive head 103 are fixedly connected. A threaded hole 135 is provided inside the support baffle 131. The threaded hole 135 is a vertical through structure used to accommodate the installation of the compression screw 133. By providing a threaded hole 135 on the support baffle 131, the conductive head 103 can form a reliable locking effect by screwing in the thread after adjusting its position. This ensures that the conductive head 103 remains stable and fixed under long-term scouring of electrolyte and continuous current action, avoiding the defect of loosening caused by long-term stress in existing anode plate conductive heads.

[0031] like Figure 1 , Figures 3-6 As shown, a compression screw 133 passes through the inside of the threaded hole 135. The compression screw 133 and the threaded hole 135 are connected by threaded engagement. The compression screw 133 can move up and down along the threaded hole 135. By tightening the compression screw 133, the conductive head 103 can be further pressed and fixed on the basis of the hook end 132 abutting the plate body 101, thereby improving the installation stability and current conduction reliability of the conductive head 103, thus improving the shortcomings of the existing bolt fixing method, which is inconvenient to adjust and susceptible to corrosion.

[0032] like Figure 1 , Figures 3-6 As shown, a trapezoidal extrusion head 134 is movably nested at the bottom of the extrusion screw 133. A screw limiting groove 136 is provided at the top of the trapezoidal extrusion head 134, and the trapezoidal extrusion head 134 is nested at the bottom of the extrusion screw 133 through the screw limiting groove 136. The trapezoidal extrusion head 134 can generate a downward pressure during the tightening of the extrusion screw 133, and form a compressive force through contact with the plate 101 to ensure that the conductive head 103 is firmly attached to the plate 101, further enhancing the stability of the conductive path and avoiding uneven current distribution.

[0033] like Figure 1 , Figures 3-6 As shown, the bottom surface of the trapezoidal extrusion head 134 is inclined, and the bottom inclined surface of the trapezoidal extrusion head 134 is in close contact with the top of the extrusion plate 101. The inclined structure can make the extrusion force evenly distributed on the plate 101, effectively reducing concentrated stress and improving the durability of the plate 101 in long-term operation; at the same time, it maintains the stability of the conductive head 103 during the electrolytic reaction process and avoids deviation in current conduction due to uneven force.

[0034] like Figure 1 , Figures 3-6 As shown, reinforcing ribs are provided between the two ends of the support baffle 131 and the conductive head 103. The reinforcing ribs are strip-shaped protrusions. The reinforcing ribs are used to improve the overall strength of the support baffle 131 and the conductive head 103, and to prevent the conductive head 103 from shifting or loosening due to electrolyte impact or mechanical vibration, thereby ensuring the overall structural stability of the anode plate and the reliability of current conduction.

[0035] Example 2:

[0036] See Figures 1-6 An adjustable anode plate structure includes a plate body 101, a conductive head 103, a support baffle 131, a pressing screw 133, and a trapezoidal pressing head 134. The plate body 101 is integrally stamped from metal material. Uniformly stamped perforated holes 111 are formed inside the plate body 101, and corresponding perforated edge plates 112 are provided. The perforated edge plates 112 are integrally connected to the plate body 101, naturally formed during the stamping process, and folded upwards along the edges of the perforated holes 111 to form a stable three-dimensional frame. The perforated edge plates 112 significantly increase the specific surface area of ​​the plate body 101, allowing the electrolyte to obtain more reaction interfaces when flowing over the surface of the plate body 101, thereby increasing the active sites of the electrolytic reaction and improving the uniformity of the current density distribution. The perforated holes 111 on the plate are arranged in a regular array, which can not only ensure the smooth flow of electrolyte and products and reduce the accumulation of by-products, but also form an effective flow channel structure with the perforated edge plate 112, further promoting the reaction rate.

[0037] An adjustment window 102 is provided at the top of the plate 101. The adjustment window 102 is a rectangular window with mechanically bent and reinforced edges to withstand the installation pressure of the conductive head 103. A hook end 132 is provided at the bottom of the conductive head 103. The hook end 132 has a downwardly bent hook-like structure, and its width matches the inner width of the adjustment window 102. During installation, the hook end 132 of the conductive head 103 is inserted into the adjustment window 102 and then hooked against the top of the plate 101, forming a preliminary fixation. A support baffle 131 is fixedly installed on one side of the conductive head 103. The support baffle 131 is connected to the conductive head 103 by welding to ensure overall strength. A through threaded hole 135 is provided inside the support baffle 131. The threaded hole 135 is a precision tapped hole for installing a pressing screw 133.

[0038] A compression screw 133 passes through a threaded hole 135 and moves up and down along the threaded hole 135 by screwing. A trapezoidal compression head 134 is movably nested at the bottom of the compression screw 133. A screw limiting groove 136 is provided at the top of the trapezoidal compression head 134, which engages with the bottom end of the compression screw 133 to ensure that the trapezoidal compression head 134 will not fall off during the stress process. The bottom surface of the trapezoidal compression head 134 is machined into a bevel, which is in close contact with the top of the plate 101. When the compression screw 133 is tightened, the trapezoidal compression head 134 moves downward, and the bevel gradually presses against the plate 101, further securing the conductive head 103 on top of the hook end 132. This ensures a tight connection between the conductive head 103 and the plate 101 and avoids the loosening problem caused by corrosion and vibration during long-term electrolysis, which is a problem with traditional bolt-through fixing methods.

[0039] Reinforcing ribs are provided at both ends of the conductive head 103 and the supporting baffle 131. The reinforcing ribs are strip-shaped protrusions and are integrally formed with the conductive head 103 by mechanical stamping. This enhances the overall strength of the conductive head 103 and the supporting baffle 131, resisting the mechanical stress caused by electrolyte erosion and current impact. Through this structural design, the anode plate can maintain stable operation for a long time in the electrolytic cell, ensuring the uniformity and reliability of current conduction.

[0040] The operation process of this embodiment is as follows: When the electrolytic cell is powered on, the plate 101, acting as the anode, is connected to the positive terminal of the power supply. When the electrolyte flows through the perforated holes 111 and comes into full contact with the perforated edge plate 112, an oxidation reaction occurs on the surface of the plate 101. The perforated edge plate 112 significantly increases the reaction interface, resulting in a more uniform distribution of current density on the surface of the plate 101 and an increased electrolysis reaction rate. Simultaneously, the electrolyte and generated gaseous products are smoothly discharged through the perforated holes 111, preventing side reactions caused by accumulation and ensuring the continuity and stability of the electrolysis process. After the conductive head 103 is installed by the hook end 132 in conjunction with the adjustment window 102, it is then fixed to the plate 101 by the pressure applied by the compression screw 133 and the trapezoidal compression head 134, ensuring that the current can be stably transmitted to the plate 101. By adjusting the compression screw 133, the conductive head 103 can also be disassembled and its position adjusted, allowing the anode plate structure to adapt to the electrolysis requirements under different working conditions, thus possessing strong practicality.

[0041] The working principle of this utility model is as follows:

[0042] Based on the hollow plate body, this scheme retains the hole folded edge plate 112 generated when the plate is made into a hollow hole 11 by stamping, which further increases the specific surface area of ​​the plate body, provides more active sites for the electrolytic reaction, improves the uniformity of current density distribution, accelerates the reaction rate and improves the electrolysis efficiency.

[0043] This design eliminates the direct bolt-fixed conductive head structure. A support baffle 131 is provided on one side of the conductive head 103, and a hook end 132 is provided at its bottom. The conductive head 103 is fixed by compression screws 133. By screwing and loosening the compression screws 133, the installation position of the conductive head 103 can be slidably adjusted as needed, making it more practical.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
