Description

Technical Field

[0001] This utility model relates to the technical field of the anode part of electrolysis equipment, and in particular to a novel sealed anode chamber. Background Technology

[0002] In the electrolytic production process, metal ions are reduced to elemental form in the cathode region, and in the anode region, hydroxide ions are oxidized to oxygen in the metal sulfate system and chloride ions are oxidized to chlorine in the metal chloride system. To prevent the oxidized gases from escaping and causing environmental pollution, the anode region is usually isolated from the cathode region by an anode chamber. In the anode chamber, the gas generated in the anode region can be extracted by vacuuming. After the gas and anolyte are extracted from the anode chamber, they are separated by a gas-liquid separator. The gas and anolyte are then processed in different processes or recycled.

[0003] For example, utility model patent application CN210065947U discloses an anode box and an electrolytic device for recovering copper from acid etching waste liquid. The anode box includes: a main body box, comprising a frame and two diaphragms. The frame is installed inside the electrolytic cell, and the two diaphragms are respectively installed on opposite sides of the frame, forming a cavity to house the anode plate of the electrolytic device for recovering copper from acid etching waste liquid; and a gas collection box, located at the top of the frame and having a collection chamber connected to the cavity. The gas collection box also has a gas outlet connected to the collection chamber, which is connected to the exhaust pipe of the electrolytic device for recovering copper from acid etching waste liquid. This design allows for a clear gas-liquid interface in the electrolytic device, effectively preventing the anode liquid from entering the exhaust pipe and causing blockage.

[0004] However, the above-mentioned device still has the following defects: The sealing of the anode chamber is crucial during gas extraction. Poor sealing will allow ambient gas to enter the anode chamber under negative pressure conditions and mix with the gas produced during electrolysis, inevitably leading to a decrease in gas purity and affecting subsequent gas utilization. Furthermore, insufficient sealing will cause gas to escape from the anode chamber, impacting the production environment. The anode plate in the electrolysis device passes through the top of the gas collection box and is installed within the frame. The connection area between the anode plate and the gas collection box is too large, increasing the risk of gas leakage. Additionally, the portion of the anode plate inside the gas collection box cannot contact the electrolyte, resulting in a waste of the anode plate and changes in the electrolyte level. The relatively fixed installation position of the top cover makes it prone to leaks between the top cover and the anode frame, or the absorption of electrolyte into the top cover. The non-fixed installation position of the anode frame means that the overall integrity, stability, and ease of installation of the anode chamber need further improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel sealed anode chamber that effectively reduces the risk of anode gas leakage, prevents external air from entering, ensures the purity of the gas collected at the anode, effectively fixes the installation position of the anode frame, and adjusts the relative position between the top cover and the anode plate, thereby improving the integrity, stability, and ease of installation of the anode chamber.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel sealed anode chamber includes an anode frame, an anode plate, a top cover, a diaphragm bag, a conductive component, and a conductive screw. The anode frame has an opening at its bottom, through which the anode plate enters the anode frame. The diaphragm bag is fitted over the anode frame. The top of the anode frame and the top cover both have through holes allowing the conductive screw to pass through. One end of the conductive screw is connected to the conductive component, and the other end passes through the through hole and is fixedly connected to the top of the anode plate. The conductive screw is equipped with a positioning nut and a sealing nut. The positioning nut is located below the upper part of the anode frame, and the sealing nut is located above the top cover and seals the through hole at the top cover. The opening of the diaphragm bag is pressed against the upper periphery of the anode frame by the inner wall of the top cover. The inner wall of the top cover and the outer wall of the anode frame are sealed by the diaphragm bag. The diaphragm bag and the top cover form a collection cavity. The top cover is provided with an exhaust pipe communicating with the inside of the collection cavity.

[0007] Preferably, the opening of the diaphragm bag is provided with a flange that bends from top to bottom; further, the bottom of the flange is lower than the bottom of the top cover, and the bottom of the top cover is immersed below the electrolyte surface.

[0008] Preferably, it also includes a sealing strip, which is fitted over the upper part of the diaphragm bag, and the opening of the diaphragm bag is tightly pressed against the anode frame by the sealing strip; furthermore, there is at least one sealing strip, which is preferably a sealing strip with a certain elasticity, or other seals with sealing and limiting strap effects can be used.

[0009] Preferably, the anode frame is provided with a first concave ring corresponding to the sealing strip, and the inner wall of the top cover is provided with a second concave ring corresponding to the sealing strip. The bag opening and flange of the diaphragm bag are pressed into the first concave ring and / or the second concave ring by the sealing strip.

[0010] Preferably, it also includes a sealing element located between the sealing nut and the top cover, wherein the sealing nut is sealed to the top cover through a through hole in the sealing element; furthermore, the sealing element may be a sealing gasket, a polytetrafluoroethylene tape, or other sealing elements with equivalent sealing effect.

[0011] Preferably, the bottom of the inner wall of the upper cover is provided with a flared portion.

[0012] Preferably, the conductive component is equipped with an arc-shaped support, which is fixedly connected to the top of the conductive screw by bolts; further, the conductive screw is fixedly locked to the conductive component by a nut.

[0013] Preferably, the anode frame is made of a lightweight, high-strength, corrosion-resistant, and temperature-resistant material.

[0014] Preferably, the diaphragm bag is provided with a tie, which extends from the top of the diaphragm bag, is tied to the top of the anode frame, and is sewn inside the diaphragm bag.

[0015] Preferably, the anode frame is provided with an adjustment hole corresponding to the positioning nut.

[0016] Compared with existing technologies, this utility model provides a novel sealed anode chamber with the following advantages: In this novel sealed anode chamber, the anode plate enters through an opening at the bottom of the anode frame. A conductive screw passes through a through hole in the anode frame and the upper cover. After the height of the anode frame and the sealing upper cover is determined by a positioning nut, the anode plate is fixed to the anode frame. Then, a sealing nut is used for positioning, sealing, and tightening, making the anode plate, anode frame, and sealing upper cover a single unit. This replaces the original method of the anode plate completely penetrating through the upper cover, greatly reducing the sealing difficulty at the upper cover. The through hole through which the conductive screw passes at the upper cover has a small diameter, facilitating sealing. This significantly reduces the risk of gas escaping from the top cover generated at the anode. By adjusting the positions of the positioning nut and sealing nut at the conductive screw, the relative position between the top cover and the anode plate can be adaptively adjusted. Depending on the properties of the collected gas, the bottom of the top cover can be appropriately adjusted to ensure it is submerged below the electrolyte surface. This effectively controls the relative position of the anode plate and the anode frame, making the anode plate, anode frame, and top cover a single unit, improving both ease of installation and the stability of the anode frame. Reducing the amount of the anode plate exposed above the electrolyte increases the reaction area of ​​an anode plate of the same size, which plays a positive role in the electrolysis of the electrolyte.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] Please refer to Figure 1-5 as well as Figures 7-8The novel sealed anode chamber specifically includes: an anode frame 1, an anode plate 2, a top cover 3, a diaphragm bag 4, a conductive component 5, and a conductive screw 6. The anode frame 1 has an opening 7 at its bottom, through which the anode plate 2 enters the anode frame 1. The diaphragm bag 4 is fitted onto the anode frame 1. The top of the anode frame 1 and the top cover 3 both have through holes 8 allowing the conductive screw 6 to pass through. One end of the conductive screw 6 is connected to the conductive component 5, and the other end of the conductive screw 6 passes through the through hole 8 and is fixedly connected to the top of the anode plate 2. The conductive screw 6 is equipped with a positioning nut 9 and a sealing nut 10. The positioning nut 9 is located below the upper part of the anode frame 1, and the sealing nut 10 is located above the upper cover 3 and seals the through hole 8 at the upper cover 3. The opening of the diaphragm bag 4 is pressed against the upper periphery of the anode frame 1 through the inner wall of the upper cover 3. The inner wall of the upper cover 3 and the outer wall of the anode frame 1 are sealed by the diaphragm bag 4. The diaphragm bag 4 and the upper cover 3 form a collection cavity 11. The upper cover 3 is provided with an exhaust pipe 12 that communicates with the inside of the collection cavity 11.

[0031] For details, please refer to Figure 1 An arc-shaped support 18 is installed on the conductive component 5, and the arc-shaped support 18 is fixedly connected to the top of the conductive screw 6 by bolts; furthermore, the conductive screw 6 is fixedly locked to the conductive component 5 by a nut.

[0032] Specifically, the anode frame 1 is made of lightweight, high-strength, corrosion-resistant, and temperature-resistant material. The anode frame 1 is preferably made of high-temperature resistant fiberglass, but other corrosion-resistant materials such as plastic can also be used. Fiberglass is not easily deformed at high temperatures, which will not cause changes in the sealing gap between the anode frame 1 and the top cover 3, thus contributing to the reliability of the seal.

[0033] The novel sealed anode chamber provided in this embodiment can distribute the load at the conductive screw 6 to the conductive component 5 through the bow-shaped support 18, avoiding concentrated stress on the conductive component 5, reducing the accident rate of conductive component 5 breakage, and improving the connection stability between the conductive screw 6 and the conductive component 5; the fiberglass and plastic materials have good corrosion resistance, which can improve the service life of the anode frame 1 and ensure the structural strength of the anode frame 1 in corrosive electrolyte; it should be noted that the bottom of the upper cover 3 in this embodiment can be immersed below the electrolyte surface to liquid seal the connection between the upper cover 3 and the diaphragm bag 4.

[0034] Example 2

[0035] The novel sealed anode chamber provided in Example 1 has been further optimized. For details, please refer to [link / reference needed]. Figures 5-6 as well as Figure 8 The diaphragm bag 4 has a flange 13 that bends from top to bottom at the bag opening; furthermore, the bottom of the flange 13 is lower than the bottom of the top cover 3, and the bottom of the top cover 3 is immersed below the electrolyte surface.

[0036] For details, please refer to Figure 6The bottom of the inner wall of the top cover 3 is provided with a flared section 17.

[0037] For details, please refer to Figures 5-6 It also includes a sealing strip 14, which is fitted onto the upper part of the diaphragm bag 4. The opening of the diaphragm bag 4 is tightly pressed against the anode frame 1 by the sealing strip 14. Furthermore, there is at least one sealing strip 14. The sealing strip 14 is preferably a sealing strip with a certain elasticity, or other sealing strips with sealing and limiting effects can be used.

[0038] For details, please refer to Figures 5-6 as well as Figure 7 The anode frame 1 is provided with a first concave ring 15 corresponding to the sealing strip 14, and the inner wall of the upper cover 3 is provided with a second concave ring 20 corresponding to the sealing strip 14. The bag opening and flange 13 of the diaphragm bag 4 are pressed against the first concave ring 15 and / or the second concave ring 20 by the sealing strip 14. Further, the sealing strip 14 is at least one; in this embodiment, two sealing strips 14 are used as an example. Both sealing strips 14 are located between the bag opening and flange 13 of the diaphragm bag 4 and are spaced apart in the vertical direction. Do not press the opening of the diaphragm bag 4 and the flange 13 into the first concave ring 15 and the second concave ring 20. However, this should not be construed as a limitation on the scope of protection of this case. The number of sealing strips 14 can be appropriately increased or decreased according to sealing requirements, and the number and position of the first concave ring 15 and the second concave ring 20 can be adjusted accordingly. In this way, the sealing strips 14 can effectively limit and tightly press the opening of the diaphragm bag 4 and the flange 13 into the inner wall of the corresponding anode frame 1 or the upper cover 3, thereby further improving the sealing performance between the upper cover 3 and the anode frame 1.

[0039] For details, please refer to Figure 1 or Figure 4 It also includes a seal 16, which is located between the sealing nut 10 and the upper cover 3. The sealing nut 10 is sealed to the upper cover 3 through the through hole 8 at the upper cover 3 via the seal 16. Furthermore, the seal 16 can be a sealing gasket, a polytetrafluoroethylene tape, or other seals 16 with equivalent sealing effect.

[0040] For details, please refer to Figure 3 or Figure 8 The diaphragm bag 4 is provided with a tie 19, which extends from the upper part of the diaphragm bag 4 and is tied to the upper part of the anode frame 1. The tie 19 is sewn inside the diaphragm bag 4. When the upper part of the diaphragm bag 4 is provided with a flange 13, the flange 13 is used to avoid interfering with the installation of the tie 19 at the anode frame 1, so as to facilitate the tie 19 to be tied to the upper part of the anode frame 1 and improve the installation convenience of the anode chamber.

[0041] For details, please refer to Figure 7The anode frame 1 is provided with adjustment holes 20 corresponding to the positioning nut 9. The adjustment holes 20 make it easy for the operator to rotate and adjust the positioning nut 9 with tools, thereby improving the convenience of operation, shortening the operation time, and improving the installation efficiency of the anode chamber.

[0042] The novel sealed anode chamber provided in this embodiment increases the thickness of the diaphragm bag 4 between the upper cover 3 and the anode frame 1 through the flange 13. The upper bend of the flange 13, under the elasticity of the diaphragm bag 4, can tightly abut against the inner wall of the upper cover 3 and the outer wall of the anode frame 1, improving the sealing performance between the upper cover 3 and the anode frame 1. This further reduces the leakage of anode gas or the entry of external gas, preventing pollution to the external environment and ensuring the purity of the collected gas. The flared portion 17 improves the smoothness of the upper cover 3 closing onto the upper part of the anode frame 1 and the upper part of the diaphragm bag 4, enhancing the ease of installation. Regardless of whether the bottom of the upper cover 3 is higher or lower than the electrolyte level, the sealing strip 14 presses the opening of the diaphragm bag 4 against the anode frame 1. Simultaneously, the sealing strip 14 also improves the tightness of the connection between the diaphragm bag 4 and the upper cover 3. To further ensure the tightness of the connection between the upper cover 3 and the anode frame 1, and to improve the sealing performance between the upper cover 3 and the anode frame 1; the first concave ring 15 and the second concave ring 20 can prevent the corresponding sealing strip 14 from sliding up and down, and the flange 13 can make the upper cover 3 pass over the corresponding sealing strip 14 more smoothly, and can also avoid the sealing strip 14 from protruding too much and interfering with the installation of the upper cover 3, and reduce the incidence of sealing defects caused by the displacement of the sealing strip 14; the sealing element 16 can seal the connection between the conductive screw 6 and the upper cover 3, and prevent gas from leaking out through the gap between the two, so as to ensure the sealing performance of the entire collection chamber 11; the tie 19 can facilitate the installation of the diaphragm bag 4 at the anode frame 1, and at the same time, the tie 19 can prevent the diaphragm bag 4 from falling down from the anode frame 1, and improve the installation stability of the diaphragm bag 4 at the anode frame 1.

[0043] The novel sealed anode chamber provided by this utility model is used as follows: The anode plate 2 is inserted into the anode frame 1 through the bottom opening 7. The conductive screw 6 passes through the corresponding through hole 8. The diaphragm bag 4 is pressed onto the anode frame 1 by the sealing strip 14. The upper part of the diaphragm bag 4 is bent and hangs down naturally to form a flange 13. The installation height of the anode frame 1 is adjusted by adjusting the installation position of the positioning nut 9 at the conductive screw 6. The upper cover 3 is placed on the top of the anode frame 1 and the sealing nut 10 is tightened. The sealing nut 10 positions the anode frame 1 and seals the through hole 8 at the upper cover 3, so that the anode plate 2, the anode frame 1 and the upper cover 3 are fixed as one unit. The conductive component 5 is connected to the external power anode. After being conductive by the conductive screw 6, the anode plate 2 electrolyzes the electrolyte. The gas generated by electrolysis accumulates in the sealed cavity formed between the upper cover 3, the diaphragm bag 4 and the electrolyte surface, and is then discharged and collected through the exhaust pipe 12.

[0044] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
