For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] like Figure 1~Figure 4 As shown, this embodiment proposes an electrolytic cell sealing plug for sealing the feed port 1 of the electrolytic cell, comprising: a plug body 2, which is sealingly fitted on the feed port 1; a first sealing ring 3 is arranged in the middle of the plug body 2, and the bottom of the first sealing ring 3 is sealingly fitted with the lower end of the feed port 1.

[0038] In this embodiment, the plug body 2 is the main part of the electrolytic cell sealing plug, and its shape and size should match the feed port 1 of the electrolytic cell to ensure that it can be tightly inserted and fixed in the feed port 1 to form an effective sealing interface. The plug body 2 is usually made of corrosion-resistant, high-temperature-resistant, and mechanically strong materials to adapt to the harsh chemical environment and working temperature inside the electrolytic cell. The surface of the plug body 2 should be smooth and burr-free to reduce scratches on the inner wall of the electrolytic cell or affect the sealing effect. The first sealing ring 3 is arranged in the middle of the plug body 2, and its bottom is sealed with the lower end of the feed port 1. The first sealing ring 3 is the main sealing element and undertakes the key task of preventing the electrolyte or gas from leaking from the gap between the feed port 1 and the plug body 2. The first sealing ring 3 can be a standard or customized sealing element such as an O-ring, a V-ring, a rectangular ring, a lip-shaped sealing ring, etc., and the material is usually rubber, polytetrafluoroethylene or other high-performance polymers, with good elasticity and chemical medium resistance. The first sealing ring 3 should fit tightly with the plug body 2 and the inner wall of the feed port 1 to form a reliable static seal. The provision of the first sealing ring 3 reduces the leakage of electrolyte in the electrolytic cell and reduces the entry of pollutants into the electrolytic cell, thereby improving the sealing performance of the sealing plug.

[0039] Optionally, it also includes: a second sealing ring 4 is arranged on the top of the plug body 2, and the bottom of the second sealing ring 4 is sealed and matched with the upper end of the feed port 1.

[0040] In this embodiment, the second sealing ring 4 is arranged at the top of the plug body 2, and its bottom is sealed with the upper end of the feed port 1. The second sealing ring 4, as an auxiliary sealing element, constructs a double-layer sealing structure together with the first sealing ring 3 to further enhance the sealing performance of the feed port 1 of the electrolytic cell, especially for possible axial pressure fluctuations, temperature changes, medium erosion, etc., to provide double insurance and reduce the risk of leakage. The structure and material selection of the second sealing ring 4 are similar to those of the first sealing ring 3, and can be standard or customized sealing elements such as O-rings, V-rings, rectangular rings, lip-shaped sealing rings, etc. The material is also required to have good elasticity and chemical resistance. The second sealing ring 4 should fit tightly with the top of the plug body 2 and the inner wall of the upper end of the feed port 1 to form a reliable static seal. The double-layer sealing design, that is, the first sealing ring 3 + the second sealing ring 4, can effectively improve the sealing reliability of the feed port 1 of the electrolytic cell. Even when a layer of sealing elements fails due to wear, aging, uneven force, etc., the other layer of sealing can still maintain the basic sealing effect to prevent sudden leakage, and win time for equipment maintenance or replacement of sealing elements. For complex working conditions such as large fluctuations in working pressure, frequent temperature changes, and highly corrosive media, double-layer sealing can provide stronger resistance and reduce maintenance costs. In summary, by adding a second sealing ring 4 on the top of the plug body 2 and sealing with the upper end of the feed port 1, a double-layer sealing structure is formed, which significantly enhances the sealing performance and reliability of the feed port 1 of the electrolytic cell.

[0041] Optionally, the feed port 1 is conical and the plug body 2 is a frustum.

[0042] In this embodiment, the feed port 1 adopts a conical design, that is, its cross-section gradually decreases from top to bottom, forming an inverted cone or a cone-like structure. This design helps the electrolyte or solid raw materials to naturally concentrate when entering the electrolytic cell, reduces the dispersion and accumulation of materials at the feed port 1, reduces the risk of materials blocking the feed port 1, and ensures that the materials enter the electrolytic cell evenly and smoothly. The plug body 2 matches the shape of the feed port 1 and is designed to be a frustum, that is, its upper cross-section is larger, which matches the conical large mouth end at the top of the feed port 1; the lower cross-section is smaller, which matches the small mouth end at the bottom of the feed port 1. Such a design ensures that the plug body 2 and the feed port 1 can form good contact and sealing in both the axial and radial directions, avoiding sealing failure or shaking of the plug body 2 due to shape mismatch. The cone-shaped plug body 2 contacts the cone-shaped feed port 1, thereby increasing the sealing contact area, so that the sealing elements (first sealing ring 3, second sealing ring 4) can obtain better support and compression in both axial and radial directions, thereby improving the stability and reliability of the seal.

[0043] Optionally, the plug body 2 has a first cavity 201 and an avoidance opening 202, the avoidance opening 202 is located on the peripheral side of the first cavity 201 and is connected to the first cavity 201; it also includes: a moving block 5, which is slidably arranged relative to the first cavity 201 and is located below the first sealing ring 3. After sliding, the moving block 5 passes through the avoidance opening 202, and the top of the moving block 5 abuts against the lower end of the feed port 1.

[0044] In this embodiment, a first cavity 201 is provided in the plug body 2 to provide a sliding space for the moving block 5. The setting of the first cavity 201 allows a structure for accommodating the moving block 5 to be formed inside the plug body 2, which helps to reduce the overall size of the plug body 2 and reduce the weight, while providing the necessary space for the installation, sliding and positioning of the moving block 5. The avoidance port 202 is located on the peripheral side of the first cavity 201 and is connected to the first cavity 201. The design of the avoidance port 202 allows the moving block 5 to extend from the first cavity 201 during the sliding process and contact the lower end of the feed port 1 to achieve a sealing or unlocking function. The shape and size of the avoidance port 202 should match the sliding track of the moving block 5 to ensure smooth sliding of the moving block 5 and reduce the leakage of electrolyte or gas from the avoidance port 202. The moving block 5 is arranged to slide relative to the first cavity 201, that is, the moving block 5 can slide freely along a predetermined track in the first cavity 201. When the moving block 5 slides through the avoidance port 202, its top abuts against the lower end of the feed port 1. Fixing the plug body 2 and the feed port 1 enhances the sealing effect and reduces the occurrence of the plug body 2 being separated from the feed port 1 due to accidental touch by the operator.

[0045] Optionally, the moving block 5 has an arc portion 501. After the moving block 5 slides, the arc portion 501 passes through the avoidance opening 202, and the top of the arc portion 501 abuts against the lower end of the feed port 1; it also includes: the turntable 6 is rotatably arranged in the first cavity 201, the turntable 6 has a second cavity 601, and the moving block 5 is slidably arranged in the second cavity 601.

[0046] In this embodiment, the second cavity 601 is arranged on the turntable 6, and the length direction of the second cavity 601 is the same as the radial direction of the turntable 6; the moving block 5 has a ramp portion 502, the ramp portion 502 has an inclined surface adapted to the outer circumference of the plug body 2, and the arc portion 501 is located at the end of the ramp portion 502. When the plug body 2 is sealed with the feed port 1, the operator can rotate the turntable 6 clockwise to move the moving block 5 along the radial direction of the turntable 6, and the inclined platform portion 502 extends through the avoidance opening 202 to the outside of the plug body 2. At this time, the upper side of the arc portion 501 abuts against the lower side of the feed port 1; when the plug body 2 needs to be taken out from the feed port 1, the operator can rotate the turntable 6 counterclockwise, and the inclined platform portion 502 contacts the outer side surface of the plug body 2. Under the pressure of the outer side surface of the plug body 2, the inclined platform portion 502 slides into the second cavity 601. At this time, the arc portion 501 retreats into the second cavity 601, and the operator can take the plug body 2 out of the feed port 1.

[0047] Optionally, it further includes: an elastic member 8, two ends of which act on the inner wall of the second cavity 601 and one end of the moving block 5 away from the arc portion 501 respectively, and the elastic member 8 is used to provide a force for moving the moving block 5 away from the second cavity 601.

[0048] Optionally, the elastic member 8 is a compression spring.

[0049] In this embodiment, the elastic member 8 provides a force between the moving block 5 and the inner wall of the second cavity 601 to always keep the moving block 5 away from the second cavity 601 (i.e., move toward the arc portion 501). When the turntable 6 rotates to release the moving block 5, the elastic force of the elastic member 8 can quickly reset the moving block 5 and tightly abut against the lower end of the feed port 1, thereby improving the sealing reliability.

[0050] Optionally, there are several avoidance openings 202, which are circumferentially distributed on the circumference of the first cavity 201, there are several second cavities 601, which are circumferentially distributed on the circumference of the turntable 6, and there are several moving blocks 5 and elastic members 8.

[0051] In this embodiment, by providing a plurality of avoidance openings 202, a second cavity 601, a moving block 5 and an elastic member 8, when the turntable 6 rotates, the plurality of moving blocks 5 can respectively pass through the plurality of avoidance openings 202, extend to the outside of the plug body 2, and abut against the lower end of the feed port 1, so that the plug body 2 and the feed port 1 are fixed more tightly, thereby improving the sealing performance.

[0052] Optionally, it further includes: a fixing rod 9 disposed on the turntable 6 , the fixing rod 9 passing through the plug body 2 and extending to above the plug body 2 ; a handle portion 10 disposed on the fixing rod 9 and located above the plug body 2 .

[0053] In this embodiment, the operator can rotate the handle portion 10 manually or using an appropriate tool to rotate the turntable 6, so that the moving block 5 slides out of the second cavity 601, thereby fixing the plug body 2 and the feed port 1.

[0054] Optionally, it further includes: a boss 11 is arranged on the plug body 2, the boss 11 has a pin hole 1101, and the pin hole 1101 is located at one side of the handle part 10; the lever 12 is snap-fitted with the pin hole 1101.

[0055] In this embodiment, when the plug body 2 needs to be taken out from the feed port 1 , the operator can engage the lever 12 with the pin hole 1101 , and then manually pull the lever 12 to take the plug body 2 out from the feed port 1 .
