Description

Technical Field

[0001] The utility model belongs to the field of aluminum electrolytic cells, and in particular relates to an anode guide rod sealing device for an electrolytic cell. Background Art

[0002] In existing technology, the anode guide rod seal for electrolytic cells primarily uses a conventional steel pressure plate to secure high-temperature insulation wool to the cell's horizontal cover. This can be easily damaged by the constant alignment of the anode guide rod during pole changes or adjustments, creating gaps that can lead to poor sealing and heat and material loss in the electrolytic cell, as well as flue gas leakage and environmental pollution. If damaged insulation wool is not promptly replaced, direct contact between the anode guide rod and the cell's horizontal cover during pole changes or adjustments can occur, causing surface damage.

[0003] Patent 201621379161.7 discloses an anode guide rod sealing device for an aluminum electrolytic cell, which is arranged between the cover plate of the aluminum electrolytic cell and the anode guide rod. The sealing device includes an insulator installed at the opening of the cover plate. A flexible seal is integrally formed on the inner side of the insulator toward the anode guide rod to seal the gap between the anode guide rod and the cover plate. Utility Model Content

[0004] In view of the above problems, the utility model provides a new electrolytic cell anode guide rod sealing device with a simple structure and good sealing effect.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is:

[0006] A sealing device for an anode guide rod of an electrolytic cell comprises an elastic pressure plate and a thermal insulation sealing material. The elastic pressure plate presses the thermal insulation sealing material onto a horizontal cover plate of the electrolytic cell and is arranged around the anode guide rod. The elastic pressure plate is relatively upwardly tilted corresponding to one end of the anode guide rod, and causes the thermal insulation sealing material to be elastically pressed against the anode guide rod and form a seal. The thermal insulation sealing material comprises a cloth bag and high-temperature resistant thermal insulation cotton, and the high-temperature resistant thermal insulation cotton is flatly stuffed into the cloth bag.

[0007] Furthermore, in the above solution, the heat insulating and heat preserving sealing material is folded over along one end of the elastic pressure plate and fixed by a bolt.

[0008] Furthermore, in the above solution, three elastic pressing plates are provided, and the three elastic pressing plates and the heat-insulating sealing material surround and form an anode guide rod sealing area; the other open surface of the anode guide rod is sealed by the electrolytic cell sealing tank cover.

[0009] Furthermore, in the above solution, the elastic pressure plate is made of 65Mn spring steel with a thickness of 1.5 mm.

[0010] Furthermore, in the above solution, the elastic pressure plate is fixedly mounted on the horizontal cover plate of the electrolytic cell via a bolt connection pair.

[0011] Furthermore, in the above solution, the cloth bags can be made of waste cloth bags from an electrolytic flue gas dust removal system.

[0012] The beneficial effects of the utility model are:

[0013] The utility model utilizes a sealing material composed of an elastic pressure plate, a cloth bag and high-temperature resistant heat-insulating cotton, which effectively solves the problem that the high-temperature resistant heat-insulating cotton is easily damaged during pole changing or pole adjustment, forming gaps and poor sealing, resulting in heat and material loss in the electrolytic cell and environmental pollution caused by smoke leakage, and the problem that the anode guide rod is easily damaged by direct contact with the horizontal cover plate of the electrolytic cell during pole changing or pole adjustment, causing damage to the surface of the anode guide rod.

[0014] The utility model has the advantages of simple structure, low cost and good sealing effect and is suitable for popularization and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a further detailed description of the implementation of the utility model in conjunction with the accompanying drawings to make the purpose, technical solution and technical effect of the utility model more clearly presented.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figure 1As shown, the elastic pressure plate 2 is made of 65Mn spring steel with a thickness of 1.5mm, or other high-quality carbon structural steel or alloy steel with a high elastic limit, good toughness and corrosion resistance, and has a certain degree of elasticity. The thermal insulation sealing material 3 can be made of discarded cloth bags 4 and high-temperature resistant thermal insulation cotton 5 from the electrolytic flue gas dust removal system. The high-temperature resistant thermal insulation cotton 5 is neatly stuffed into the cloth bags 4 so that the cloth bags 4 wrap around the high-temperature resistant thermal insulation cotton 5. The elastic pressure plate 2 presses the thermal insulation sealing material 3 onto the horizontal cover plate 1 of the electrolytic cell and is arranged around the anode guide rod 6. The elastic pressure plate 2 is relatively upward at one end corresponding to the anode guide rod 6, so that the thermal insulation sealing material 3 is pressed against the anode guide rod 6 to form a seal.

[0021] Specifically, three elastic pressure plates 2 are provided, and these three elastic pressure plates 2 and the thermal insulation sealing material 3 surround and form a sealing area around the anode guide rod 6. The other open surface of the anode guide rod 6 is sealed by the electrolytic cell sealing cover. The thermal insulation sealing material 3 is first secured to the upturned end of the elastic pressure plate 2 using a bolt connection pair. The entire assembly is then secured to the electrolytic cell horizontal cover plate 1, with the elastic pressure plates 2 slightly protruding from the horizontal surface of the electrolytic cell horizontal cover plate 1, forming the electrolytic cell anode guide rod sealing device.

[0022] The angle of the elastic pressure plate 2 can be adjusted according to actual conditions so that the elastic force of the elastic pressure plate 2 can just make the thermal insulation sealing material 3 close to the surface of the anode guide rod 6 to form a good seal. Moreover, since the elastic pressure plate 2 has a certain elasticity and the thermal insulation sealing material 3 is a flexible material, it will not get stuck when changing poles.

[0023] The electrolytic cell anode guide rod sealing device of the present invention comprises an elastic pressure plate 2 made of 1.5mm thick 65Mn spring steel, or other high-quality carbon structural steel or alloy steel with a high elastic limit, good toughness, and corrosion resistance, and exhibiting a certain degree of elasticity. The thermal insulation sealing material 3 can be made of a discarded cloth bag 4 and high-temperature insulating cotton 5, which is neatly inserted into the cloth bag 4 so that the cloth bag 4 encases the high-temperature insulating cotton 5. The thermal insulation sealing material 3 is first secured to the upturned end of the elastic pressure plate 2 using a bolt connection pair, and then the entire assembly is secured to the electrolytic cell horizontal cover plate 1, forming a sealing device for the electrolytic cell anode guide rod 6. This device utilizes the elasticity of the elastic pressure plate 2 to ensure that the thermal insulation sealing material 3 adheres tightly to the surface of the anode guide rod 6, creating a good seal. A sealing area surrounding the anode guide rod 6 is formed on three sides, while the other open side of the anode guide rod 6 is sealed by the electrolytic cell sealing tank cover.

[0024] The thermal insulation sealing material 3 can be made from waste cloth bags 4 and high-temperature resistant insulation cotton 5. The cloth bags can withstand temperatures of up to 200-400°C and have a certain strength, toughness, and elasticity, which can protect the high-temperature resistant insulation cotton 5. The resulting thermal insulation sealing material 3 is not easy to spread out during pole changing and adjustment, and is not easily damaged, thus having a long service life. If only high-temperature resistant insulation cotton 5 is used as the thermal insulation sealing material 3, it will not be easy to fix and will easily spread out after collision, thus shortening its service life.

[0025] The angle of the elastic pressure plate 2 can be adjusted manually. The operator can use a wrench to adjust the angle of the elastic pressure plate 2 according to actual conditions so that the elastic force of the elastic pressure plate 2 can just make the thermal insulation sealing material 3 close to the surface of the anode guide rod 6 to form a good seal. Moreover, since the pressure plate 2 has a certain elasticity and the thermal insulation sealing material 3 is a flexible material, it will not get stuck when changing poles.

[0026] The production and use process of this utility model is as follows:

[0027] The elastic pressure plate 2 is made of 1.5mm thick 65Mn spring steel, or other high-quality carbon structural steel or alloy steel with a high elastic limit, good toughness, and corrosion resistance, and has a certain degree of elasticity. The thermal insulation sealing material 3 can be made from discarded cloth bags 4 and high-temperature insulation cotton 5 from the electrolytic flue gas dust removal system. The high-temperature insulation cotton 5 is neatly inserted into the cloth bags 4 so that the cloth bags 4 encase the high-temperature insulation cotton 5. The thermal insulation sealing material 3 is first secured to the upturned end of the elastic pressure plate 2 using a bolt connection pair, and then the entire assembly is fixed to the horizontal cover plate 1 of the electrolytic cell, forming a sealing device for the electrolytic cell's anode guide rod 6. This device utilizes the elasticity of the elastic pressure plate 2 to ensure that the thermal insulation sealing material 3 adheres tightly to the surface of the anode guide rod 6, ensuring a good seal.
