Description

Technical Field

[0001] The utility model relates to a positioning device for welding an anode circulation plate of an ion membrane electrolyzer, belonging to the field of anode circulation plate positioning and welding. Background Art

[0002] The anode circulation plate is an important structural component in the ion membrane electrolyzer, which plays a positive role in improving the performance and operational reliability of the overall electrolysis device. Its main function is to optimize the flow distribution of the electrolyte inside the electrolyzer to promote the efficiency and stability of the electrolysis process, which is specifically manifested in the following aspects:

[0003] 1. Guiding the flow of electrolyte: The anode circulation plate can reasonably guide the electrolyte to be evenly distributed on the anode surface through its designed shape and position, ensuring that the electrolytic reaction is carried out as evenly as possible on the anode surface, avoiding local overheating or insufficient reaction.

[0004] 2. Enhanced mass transfer effect: The circulation plate helps the ions in the electrolyte to better contact the anode surface, improve the mass transfer efficiency, and thus increase the electrolysis reaction rate and current efficiency.

[0005] 3. Improve gas escape: Chlorine gas will be generated at the anode during the electrolysis process. The design of the circulation plate helps the gas to smoothly leave the electrolyte, reduce the retention of gas on the electrode surface, prevent bubbles from hindering the flow of electrolyte and electrode contact, and thus maintain the effective mass transfer space in the electrolytic cell.

[0032] like Figure 1-4 As shown, a positioning device for welding anode circulation plates of an ion membrane electrolyzer in this embodiment includes a first lining plate 1 and a second lining plate 2. The top of the first lining plate 1 is inclined downward from left to right, and the top of the first lining plate 1 is convex upward to form a close-fitting portion 11. A gap is provided between the close-fitting portion 11 and the right side wall of the first lining plate 1. During welding, the electrolytic cell 4 is placed horizontally, and the sealing surface of the electrolytic cell 4 is placed to the left. The first lining plate 1 and the second lining plate 2 are both placed in the electrolytic cell 4, and the first lining plate 1 and the second lining plate 2 are both located between two adjacent anode rib plates 5 of the same group. The first lining plate 1 and the second lining plate 2 are distributed from left to right, and the left side wall of the close-fitting portion 11 is close to the sealing surface of the electrolytic cell 4. Subsequently, the circulation plate 6 is placed on the first lining plate 1, and the bottom of the circulation plate 6 is in contact with the inclined surface of the top of the first lining plate 1. In this way, the circulation plate 6 is realized. The support of the ring plate 6 during the welding process is that the left side wall of the circulation plate 6 is in close contact with the right side wall of the close-fitting portion 11, so that the left and right direction positioning of the circulation plate 6 during the welding process is achieved, and the right side of the circulation plate 6 is placed on the second lining plate 2, and the support of the right side of the circulation plate 6 is achieved through the second lining plate 2. In this way, the support of the left and right sides of the bottom of the circulation plate 6 is achieved through the first lining plate 1 and the second lining plate 2. Then, the circulation plate 6 and the two adjacent anode rib plates 5 are welded by the welding equipment 7. The welding equipment 7 can be a suspended clamp-type welding machine. After welding, in fact, the first lining plate 1 is made of flexible material and is easy to bend. The first lining plate 1 can be pulled out of the gap between the circulation plate 6 and the sealing surface of the electrolytic cell 4, and finally the second lining plate 2 is taken out. In this way, the support and positioning of the circulation plate 6 during the welding process are achieved, and the operation is convenient and the work efficiency is high.

[0033] In order to facilitate the extraction of the first lining plate 1 after welding, a positioning block 3 is also included. During the welding process, the left side wall of the positioning block 3 is first pressed against the sealing surface of the electrolytic cell 4, and the left side wall of the first lining plate 1 is pressed against the right side wall of the positioning block 3. After welding is completed, the positioning block 3 is first taken out, and then the first lining plate 1 is extracted from the gap between the circulation plate 6 and the sealing surface of the electrolytic cell 4. Here, by setting the positioning block 3, the gap between the circulation plate 6 and the sealing surface of the electrolytic cell 4 can be increased, which is convenient for the extraction of the first lining plate 1. Of course, the left and right dimensions of the positioning block 3 can also be adjusted according to the actual welding position of the circulation plate 6.

[0034] The first lining plate 1 is made of rubber, which is soft and easy to be pulled out from the gap between the circulation plate 6 and the sealing surface of the electrolytic cell 4;

[0035] The top of the first lining plate 1 is provided with three first grooves 12, which are spaced from left to right, and are all located on the right side of the close-fitting portion 11. The first grooves 12 are provided to facilitate the bending of the first lining plate 1 when it is pulled out from the gap between the circulation plate 6 and the sealing surface of the electrolytic cell 4.

[0036] In addition, the first groove 12 extends to the front and rear sides of the first lining plate 1, so that four supporting points are formed on the inclined surface of the first lining plate 1. According to the actual welding requirements, the positions of the three first grooves 12 are determined so that the positions of the four supporting points are consistent with the welding positions of the circulation plate 6. In this way, according to the positions of the four supporting points, not only the positions of the welding points of the circulation plate 6 can be determined, but also the consistency of the welding points of the circulation plate 6 can be improved, thereby improving the product quality.

[0037] The top of the second lining plate 2 is concave to form a second groove 21, and the second groove 21 extends to the left side wall of the second lining plate 2. The bottom of the second groove 21 is tilted downward from left to right. When determining the welding position of the circulation plate 6, the right side wall of the circulation plate 6 is pressed against the left inner wall of the second groove 21. At the same time, the bottom of the circulation plate 6 is pressed against the bottom of the second groove 21. According to the size calculation, the inclination angle of the bottom of the second groove 21 is consistent with the inclination angle of the top of the first groove 12, which facilitates the bottom of the circulation plate 6 to fit with the bottom of the second groove 21, thereby improving the supporting effect of the second lining plate 2 on the circulation plate 6;

[0038] To sum up, the support of the circulation plate 6 by the first lining plate 1 and the second lining plate 2 realizes the support and positioning of the circulation plate 6 during the welding process, and the operation is convenient and the work efficiency is high. In addition, by setting the first groove 12 on the first lining plate 1, a support point for determining the welding point of the circulation plate 6 is formed, which not only determines the welding position of the circulation plate 6, but also improves the consistency of the welding point of the circulation plate 6, thereby improving product quality.

[0039] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
