Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis, in particular to an electrolyte tank protection structure. Background Art

[0002] Electrolyte is the main material in aluminum electrolysis production. The main component of electrolyte is cryolite. During the electrolytic aluminum production process, it is necessary to ensure the appropriate amount of electrolyte. Too much or too little electrolyte will seriously affect the normal electrolysis of aluminum liquid.

[0003] During the aluminum electrolysis process, when there is too much electrolyte, the electrolyte will be taken out and placed in the electrolyte tank. When the amount of electrolyte is small, the electrolyte in the electrolyte tank will be taken out and added. Since the melting point of the electrolyte is above 1000°C, the electrolyte in the electrolyte tank is exposed in the electrolysis workshop, which is very unsafe and poses a safety hazard. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an electrolyte tank protection structure, which can protect the electrolyte, avoid harm to workers, eliminate safety hazards, and effectively solve the problems in the background technology.

[0006] As a preferred technical solution of the present invention, both ends of the inner side of the cover frame are rotatably connected to a rotating shaft, and the cover plate is fixed to the outer side of the rotating shaft.

[0007] As an optimal technical solution of the present invention, the driving mechanism includes a bidirectional piston cylinder, a rack and a gear. The bidirectional piston cylinder is fixed on one side of the cover frame. The piston cylinders at both ends of the bidirectional piston cylinder are connected to the rack. One end of the rotating shaft passes through the cover frame and is connected to the gear. The gear is meshed with the rack.

[0008] As a preferred technical solution of the present invention, a limiting plate is provided on the outer side of the electrolyte tank, and the lower end of the cover frame is fixedly connected to the limiting plate.

[0016] The following will be combined with the drawings in the embodiment of the present invention to clearly and completely describe the technical solutions in the embodiment of the present invention. Obviously, the embodiment described is only a part of the embodiment of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0017] See also Figure 1-4The utility model provides a technical solution: an electrolyte tank protection structure, including an electrolyte tank 1, a cover frame 3 for covering the opening of the electrolyte tank 1 is arranged above the electrolyte tank 1, the outer side of the cover frame 3 is coated with a heat insulation layer, the middle of the cover frame 3 is a square through hole, and the size of the square through hole is not less than the outer size of the electrolyte tank 1, the upper end of the cover frame 3 is movably connected to two cover plates 4, one side of the cover frame 3 is provided with a driving mechanism 5 for controlling the opening and closing of the cover plate 4, the inner ends of the cover frame 3 are respectively rotatably connected to a rotating shaft 6, the cover plate 4 is fixed to the outer side of the rotating shaft 6, the driving mechanism 5 includes a bidirectional piston cylinder 51, a rack 53 and a gear 54, and the bidirectional piston gas The cylinder 51 is fixed to one side of the cover frame 3, and the piston cylinders 52 at both ends of the two-way piston cylinder 51 are connected to the rack 53. One end of the rotating shaft 6 passes through the cover frame 3 and is connected to the gear 54. The gear 54 is meshed with the rack 53. In order to prevent the influence of high temperature on the driving mechanism 5, the rotating shaft 6, the gear 54 and the rack 53 are all made of high-temperature resistant materials. By controlling the extension and contraction of the two-way piston cylinder 51, the reciprocating linear motion of the rack 53 is driven, and the clockwise or counterclockwise rotation of the gear 54 is controlled, and finally the purpose of opening and closing the cover plate 4 is achieved, so that the electrolyte is not exposed to the air, preventing workers from touching the electrolyte, and ensuring the personal safety of workers.

[0018] Furthermore, a limiting plate 2 is provided on the outer side of the electrolyte tank 1, and the lower end of the cover frame 3 is fixedly connected to the limiting plate 2. By providing the limiting plate 2, the position of the cover frame 3 can be fixed, and at the same time, the safety height for taking the electrolyte is increased to avoid burns to the skin when taking the electrolyte at close range.

[0019] Furthermore, in order to improve the sealing performance of the cover plate 4 when it is in the closed state, a step surface 7 is provided on the inner side surface of the cover frame 3. When the cover plate 4 is closed, the lower surface of the cover plate 4 contacts the step surface 7, which can provide good support for the cover plate 4 and improve the sealing performance.

[0020] During use: when it is necessary to take out electrolyte from the electrolyte tank 1 or put electrolyte into the electrolyte tank 1, the two-way piston cylinder 51 is started to control the two racks 53 to move linearly, thereby driving the gear 54 to rotate, so that the two cover plates 4 are opened; when it is necessary to close, the two-way piston cylinder 51 controls the piston rod 52 to retract, the rack 53 to move in the opposite direction, thereby driving the gear 54 to rotate in the opposite direction, so that the two cover plates 4 are closed.

[0021] The utility model adds a cover frame 3 and a cover plate 4 on the upper end thereof on the basis of the original electrolyte tank 1, and realizes opening or closing of the electrolyte tank 1 by controlling the opening and closing of the cover plate 4, thereby avoiding the safety hazard of exposed electrolyte and ensuring the personal safety of workers.
