Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cells, in particular to a sealing structure for preventing leakage of an electrolytic cell. Background Art

[0002] A water electrolyzer is a unit device consisting of several electrolysis chambers and other components. The electrolyzer consists of a cell body, an anode, and a cathode. Most of the time, a diaphragm is used to separate the anode chamber from the cathode chamber. According to the different electrolytes, it is divided into three categories: aqueous solution electrolyzer, molten salt electrolyzer, and non-aqueous solution electrolyzer. When direct current passes through the electrolyzer, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. Optimizing the design of the electrolyzer structure and rationally selecting electrode and diaphragm materials are the key to improving current efficiency, reducing cell voltage, and saving energy consumption.

[0003] When sealing an existing electrolytic water tank, the shell of the electrolysis device and the sealing ring need to be installed on the water tank by screws. In actual use, it is found that the sealing ring is generally made of rubber. After long-term use and encountering various chemical reactions, it will age and harden itself, and its elasticity will decrease, resulting in its sealing effect at the sealing gap between the shell and the water tank being deteriorated. Therefore, we propose an anti-leakage sealing structure for the electrolytic tank to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a leakage-proof sealing structure of an electrolytic cell to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A first through hole and a second through hole are vertically distributed and interconnected at the top port of the electrolytic cell body. A first long strip is movably connected in the first through hole, and a second long strip is movably connected in the second through hole. The ends of the first long strip and the second long strip that are close to each other are wedge-shaped and slidably connected to each other.

[0008] The anti-leakage sealing structure of the electrolytic cell as described above: the inner surface size of the end cover is adapted to the outer surface size of the top port of the electrolytic cell body, and the end cover is movably connected to the top port of the electrolytic cell body to seal the top port of the electrolytic cell body.

[0009] In the above-mentioned anti-leakage sealing structure for an electrolytic cell, the outer dimensions of the first sealing strip and the second sealing strip are adapted to the inner dimensions of the sealing groove, and the first sealing strip and the second sealing strip are movably snapped into the sealing groove.

[0010] As described above, a sealing structure for preventing leakage of an electrolytic cell: the number of the first through holes is set to be multiple, the first through holes are evenly spaced at the top port of the electrolytic cell body, the outer surface size of the first long strip is adapted to the inner surface size of the first through holes, and the upper end surface of the first long strip is smooth.

[0011] As described above, a sealing structure for preventing leakage of an electrolytic cell: the number of the second long strips is set to be multiple, the second long strips are evenly distributed on the inner wall of the sealing groove, the outer surface dimensions of the second long strips are adapted to the inner surface dimensions of the second through holes, and the surface of one end of the second long strips is smooth and in contact with the surface of the first sealing strip.

[0012] As described above, a sealing structure for preventing leakage of an electrolytic cell: the clamping structure includes clamping slots opened at both ends of a first sealing strip and clamping blocks fixed at both ends of a second sealing strip, the outer dimensions of the clamping blocks are adapted to the inner dimensions of the clamping slots, and the clamping blocks are movably clamped inside the clamping slots.

[0013] The anti-leakage sealing structure of the electrolytic cell as described above: mounting holes are respectively provided at the top port of the electrolytic cell body and on the end cover, and the electrolytic cell body and the end cover are fixedly connected by mounting bolts in the mounting holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the top port of the electrolytic cell body is movably connected with an end cover, and the sealing groove is embedded with a first sealing strip and a second sealing strip;

[0015] A first through hole and a second through hole are vertically distributed and interconnected at the top port of the electrolytic cell body. A first long plate is movably connected in the first through hole, and a second long plate is movably connected in the second through hole. The ends of the first long plate and the second long plate that are close to each other are wedge-shaped and slidably connected to each other.

[0016] Therefore, when sealing the electrolytic cell body and the end cover, the assembled first sealing strip and the second sealing strip are clamped and placed in the sealing groove, and the end cover is clamped at the top port of the electrolytic cell body to seal it. The first sealing strip and the second sealing strip are arranged at the sealing gap between the electrolytic cell body and the end cover to seal the electrolytic cell body and the end cover.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figures 1 to 4 As an embodiment of the present invention, a sealing structure for preventing leakage of an electrolytic cell includes a sealing groove 3 provided on the outer wall of a top port of an electrolytic cell body 1, an end cover 2 being movably clamped to the top port of the electrolytic cell body 1, a first sealing strip 4 and a second sealing strip 5 being embedded and clamped in the sealing groove 3, and the first sealing strip 4 and the second sealing strip 5 being assembled and connected by a clamping structure;

[0024] A first through hole 6 and a second through hole 7 are vertically distributed and interconnected at the top port of the electrolytic cell body 1. A first long plate 8 is movably connected in the first through hole 6, and a second long plate 9 is movably connected in the second through hole 7. The ends of the first long plate 8 and the second long plate 9 that are close to each other are wedge-shaped and slidably connected to each other.

[0025] In this embodiment, when sealing the electrolytic cell body 1 and the end cover 2, the assembled first sealing strip 4 and second sealing strip 5 are clamped and placed in the sealing groove 3, and the end cover 2 is clamped at the top port of the electrolytic cell body 1 to seal it. The first sealing strip 4 and the second sealing strip 5 are arranged at the sealing gap between the electrolytic cell body 1 and the end cover 2 to seal the electrolytic cell body 1 and the end cover 2. In order to prevent the first sealing strip 4 from aging and hardening due to long-term use and reducing its elasticity, when the end cover 2 is pressed down on the port of the electrolytic cell body 1, it will simultaneously squeeze the first long strip 8, thereby squeezing the second long strip 9 at the bottom end of the first long strip 8, thereby driving the second long strip 9 to slide, and then using the second long strip 9 to push the first sealing strip 4 outward, so that even if the elasticity of the first sealing strip 4 is reduced, it can fully fill the sealing gap between the electrolytic cell body 1 and the end cover 2, thereby ensuring the sealing effect.

[0026] As a further solution of the present invention, the inner dimensions of the end cover 2 are adapted to the outer dimensions of the top port of the electrolytic cell body 1 , and the end cover 2 is movably connected to the top port of the electrolytic cell body 1 to close the top port of the electrolytic cell body 1 .

[0027] In this embodiment, the top port of the electrolytic cell body 1 is closed by snapping the end cover 2 onto the top port of the electrolytic cell body 1 .

[0028] As a further solution of the present invention, the outer dimensions of the first sealing strip 4 and the second sealing strip 5 are adapted to the inner dimensions of the sealing groove 3 , and the first sealing strip 4 and the second sealing strip 5 are movably snap-fitted into the sealing groove 3 .

[0029] In this embodiment, the first sealing strip 4 and the second sealing strip 5 are assembled and clamped in the sealing groove 3 to seal the fitting gap between the electrolytic cell body 1 and the end cover 2 .

[0030] As a further solution of the present invention, the number of the first through holes 6 is set to be multiple, the first through holes 6 are evenly spaced at the top port of the electrolytic cell body 1, the outer dimensions of the first long plate 8 are adapted to the inner dimensions of the first through holes 6, and the upper end surface of the first long plate 8 is smooth; the number of the second long plates 9 is set to be multiple, the second long plates 9 are evenly spaced at the inner wall of the sealing groove 3, the outer dimensions of the second long plates 9 are adapted to the inner dimensions of the second through holes 7, and one end surface of the second long plate 9 is smooth and in contact with the surface of the first sealing strip 4.

[0031] In this embodiment, when the end cover 2 is pressed down on the port of the electrolytic cell body 1, multiple first long strips 8 are squeezed at the same time, thereby squeezing the second long strips 9 at the bottom end of the first long strips 8 through the first long strips 8, thereby driving the second long strips 9 to slide in the second through hole 7, and thereby using the second long strips 9 to slide outward to push the first sealing strip 4 outward.

[0032] As a further solution of the present invention, the clamping structure includes a clamping groove 10 opened at both ends of the first sealing strip 4 and a clamping block 11 fixed at both ends of the second sealing strip 5. The outer dimensions of the clamping block 11 are adapted to the inner dimensions of the clamping groove 10, and the clamping block 11 is movably clamped inside the clamping groove 10.

[0033] In this embodiment, the first sealing strip 4 and the second sealing strip 5 are assembled and installed by movably engaging the clamping block 11 in the clamping slot 10. At the same time, when the end cover 2 is removed, the first sealing strip 4 can be reset by squeezing the second sealing strip 5 against the first sealing strip 4, thereby pushing the second long strip 9 to reset and pushing the first long strip 8 upward to reset.

[0034] As a further solution of the present invention, mounting holes are respectively provided at the top port of the electrolytic cell body 1 and on the end cover 2 , and the electrolytic cell body 1 and the end cover 2 are fixedly connected by mounting bolts in the mounting holes.

[0035] In this embodiment, the electrolytic cell body 1 and the end cover 2 are connected by bolts, and the end cover 2 is fixed to the top port of the electrolytic cell body 1 by bolts.

[0036] The working principle of the utility model is as follows: when sealing between the electrolytic cell body 1 and the end cover 2, the assembled first sealing strip 4 and the second sealing strip 5 are clamped and placed in the sealing groove 3 through the clamping structure, and the end cover 2 is clamped at the top port of the electrolytic cell body 1 to seal it. The first sealing strip 4 and the second sealing strip 5 are arranged at the sealing gap between the electrolytic cell body 1 and the end cover 2 to seal between the electrolytic cell body 1 and the end cover 2. In order to prevent the first sealing strip 4 from aging and hardening due to long-term use and reducing its elasticity, when the end cover 2 is pressed down at the port of the electrolytic cell body 1, it will simultaneously clamp the second sealing strip 4 and the end cover 2. One long strip 8 is squeezed, thereby squeezing the second long strip 9 at the bottom end of the first long strip 8, thereby driving the second long strip 9 to slide, and using the second long strip 9 to push the first sealing strip 4 outward, so that even if the elasticity of the first sealing strip 4 is reduced, it can still be fully filled in the sealing gap between the electrolytic cell body 1 and the end cover 2 to ensure the sealing effect. At the same time, when the end cover 2 is removed, the second sealing strip 5 is used to squeeze the first sealing strip 4 to reset the first sealing strip 4, thereby pushing the second long strip 9 to reset, and pushing the first long strip 8 to push up and reset.

[0037] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
