Description

Technical Field

[0001] This utility model relates to the field of electrolysis technology, and in particular to a temporary sealing structure for leakage points at the outlet of an electrolytic cell. Background Technology

[0002] During the operation of electrolytic cells (such as water electrolysis hydrogen production cells and chlor-alkali industrial electrolytic cells), corrosion of the electrolyte, sand holes in the plates, and collisions with tools can cause damage to the electrolytic cells and create leaks. Leaks are usually circular holes. The occurrence of leaks can not only lead to equipment shutdown and reduced production, but also cause a chain of safety accidents. Therefore, leaks are usually repaired.

[0003] Traditional remedies typically involve welding repairs; however, welding repairs of leaks in electrolytic cells require shutdowns and production stoppages, which are costly and time-consuming. Furthermore, secondary leaks are likely to occur in the short term after repairs, resulting in unsatisfactory sealing effects.

[0004] Therefore, there is an urgent need for a temporary sealing structure that can ensure continuous production and has strong sealing performance. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please refer to Figure 1-6 A temporary sealing structure for a leak at the outlet of an electrolytic cell includes a reference ring 1. The bottom of the outer circumference of the reference ring 1 is fixed to the wall of the electrolytic cell by electric welding. When the electrolytic cell does not need temporary sealing, it can be cut and disassembled. The bottom of the reference ring 1 is provided with four guide grooves, and movable telescopic pieces 11 are provided in the guide grooves. The ends of the telescopic pieces 11 are provided with rubber sealing pieces 12. A sealing step 4 that can move up and down is provided directly above the reference ring 1. The sealing step 4 is circular and can cooperate with the reference ring 1 when it moves downward.

[0023] When using it, first locate the leak point of the electrolytic cell, align the center of the reference ring 1 with the leak point, and then weld and fix the reference ring 1. Next, push the four telescopic pieces 11 so that they all move towards the center until the four rubber sealing pieces 12 come into contact with each other. After they come into contact with each other, the leak point is blocked. Then move the sealing step 4 downward so that the sealing step 4 is tightly fastened inside the reference ring 1 to achieve temporary sealing of the leak point.

[0024] The reference ring 1 is also provided with a plurality of positioning bolts 13 on its surface. The positioning bolts 13 correspond one-to-one with the telescopic pieces 11 and are located directly above the telescopic pieces 11. When the telescopic pieces 11 move to the required position (the four rubber sealing pieces 12 contact each other), the positioning bolts 13 pass through the reference ring 1 and abut the telescopic pieces 11 against the electrolytic cell. At this time, the telescopic pieces 11 will not loosen, ensuring the temporary sealing effect.

[0025] To ensure the sealing step 4 can move up and down, two extension rods 2 are symmetrically arranged on the surface of the reference ring 1. The top of the extension rod 2 is provided with a support plate 3. The middle of the support plate 3 is provided with a screw 5. The top of the screw 5 is provided with a rotating handle 51. The surface of the sealing step 4 is provided with a bearing 41. The bottom of the screw 5 passes through the support plate 3 and cooperates with the bearing 41. When the screw 5 rotates, it drives the sealing step 4 to move up and down.

[0026] When the sealing step 4 moves downward, the protruding part below engages with the reference ring 1, thereby squeezing the leak point and improving the sealing effect.

[0027] To further improve the sealing effect, a compression protrusion 43 is provided at the bottom center of the sealing step 4. The compression protrusion 43 is located directly above the leak point. The compression protrusion 43 is a hemispherical solid steel ball. After the sealing step 4 moves downward, the rubber sealing sheet 12 is pressed onto the leak point through the compression protrusion 43. In addition, a rubber layer is provided on the circumferential surface of the compression protrusion 43.

[0028] Please refer to this again. Figure 3 In this embodiment, the rubber sealing sheet 12 is in the shape of an isosceles right trapezoid, and the leakage point is sealed when four rubber sealing sheets 12 come into contact; as Figure 4 As shown, after sealing, the sealing step 4 moves downward. As the sealing step 4 moves, the bottom extrusion protrusion 43 can gradually contact the intersection (leak point) of the four rubber sealing pieces 12. As the extrusion force increases, the rubber layer on the circumferential surface of the rubber sealing piece 12 and the extrusion protrusion 43 both deform, thereby increasing the sealing effect on the leak point.

[0029] As a preferred embodiment, the circumference of the sealing step 4 is further provided with a rubber ring 42. The rubber ring 42 is bonded to the circumference of the sealing step 4 in a stepped shape. The sealing step 4 is press-fitted with the reference ring 1 through the rubber ring 42. After the fit is made, the deformation of the rubber ring 42 can fill the gap between the reference ring 1 and the sealing step 4, making the overall connection tighter.

[0030] This structure does not require shutdown during sealing, and has low cost. When using it, first locate the leak point in the electrolytic cell, align the center of the reference ring 1 with the leak point, and then weld the reference ring 1 to the wall of the electrolytic cell.

[0031] Next, push the telescopic piece 11 to make the multiple rubber sealing pieces 12 contact each other at the leak point;

[0032] Then turn the handle 51 to rotate the screw 5 and move the sealing step 4 downward. As the sealing step 4 moves downward, the extrusion protrusion 43 gradually extrudes the intersection of multiple rubber sealing pieces 12.

[0033] Since the intersection of the extrusion protrusion 43, the multiple rubber sealing pieces 12, and the leak point are located on the same vertical line, as the extrusion force increases, the rubber layer on the circumferential surface of the rubber sealing piece 12 and the extrusion protrusion 43 both deform, thereby increasing the sealing effect on the leak point, achieving temporary sealing of the leak point, and ensuring the sealing performance of the sealed part.

[0034] When the electrolytic cell requires maintenance or does not require temporary sealing, the weld point of the reference ring 1 can be cut off by grinding wheel to remove the temporary sealing structure.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
