Description

Technical Field

[0001] The utility model relates to a locking device for the end slot cover plate of an aluminum electrolysis cell, belonging to the field of locking tools for the end slot cover plate of an aluminum electrolysis cell. Background Art

[0002] During the aluminum electrolysis production process, the slot cover plates at the tapping end and the flue end of the electrolysis cell are the most frequently opened and closed cover plates. During use, the left and right cover plates of the slot cover plate are locked by fixing pins. Although this can play a locking role, the applicant found that in the production workshop, the fixing pins are prone to collide with production equipment such as material taking equipment, resulting in bending and affecting the opening of the cover plate, thus seriously delaying production.

[0003] That is, there is a need for a locking device for the end slot cover plate of an aluminum electrolysis cell, which can stably lock the slot cover plate and facilitate the opening of the slot cover plate at the same time. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a locking device for the end slot cover plate of an aluminum electrolysis cell, which can stably lock the slot cover plate and facilitate the opening of the slot cover plate at the same time; it can overcome the deficiencies of the prior art.

[0005] The purpose of the utility model is realized by the following technical solutions:

[0006] The utility model discloses a locking device for the end slot cover plate of an aluminum electrolysis cell, which includes the slot cover plates at the tapping end and the flue end of the electrolysis cell. The slot cover plates include a cover plate frame and a left cover plate and a right cover plate located on the cover plate frame. An "L"-shaped limiting plate is hinged on the cover plate frame above the closing seam of the left cover plate and the right cover plate. The "L"-shaped limiting plate is turned up and down to vacate the space for opening and closing the slot cover plate or limit the slot cover plate.

[0007] As described above, a heat insulation plate is fixed on the electrolysis cell close to the slot cover plate, and a magnet cooperating with the "L"-shaped limiting plate is arranged on the isolation plate.

[0008] As described above, the device further includes a closing seam shielding plate connected with the "L"-shaped limiting plate.

[0009] As described above, refractory cotton is arranged on the inner side of the closing seam shielding plate.

[0010] As mentioned above, a handle is arranged on the "L"-shaped limiting plate or the closing seam shielding plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the "L"-shaped limiting plate of the present utility model rotates upward, it can create a space for the opening and closing of the trough cover plate. At the same time, after the trough cover plate is closed, by rotating the "L"-shaped limiting plate downward, the "L"-shaped limiting plate can limit the trough cover plate and prevent it from opening. In this way, the "L"-shaped limiting plate is located above the trough cover plate and is not easily contacted with material handling equipment, etc. At the same time, its structure is an integral iron plate, which is installed by means of hinges such as hinges. The structure is simple, durable, and easy to operate, suitable for the frequent opening and closing of the trough cover plate.

[0013] 2. A heat insulation plate is fixed on the electrolytic trough near the trough cover plate, and a magnet that cooperates with the "L"-shaped limiting plate is provided on the isolation plate. When the trough cover plate is opened, the magnet can fix the position of the upward-rotating "L"-shaped limiting plate, facilitating the subsequent closing of the trough cover plate.

[0014] 3. The "L"-shaped limiting plate is provided with a closing seam shielding plate. Because the closing seam will become larger after long-term use of the cover plate, which poses a safety hazard to production workers in the positive direction of the closing seam. Therefore, the closing seam can be shielded through the closing seam shielding plate. At the same time, compared with the embodiment of manually rotating the "L"-shaped limiting plate, it is convenient for workers of all heights to rotate the "L"-shaped limiting plate by lifting the closing seam shielding plate to create a space for opening and closing the trough cover plate.

[0015] Other advantages, objectives, and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, they will be obvious to those skilled in the art based on the study of the following text, or can be learned from the practice of the present utility model.

[0022] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. It should be understood that the preferred embodiments are only for explaining the present invention and not for limiting the protection scope of the present invention.

[0023] Embodiment 1

[0024] As Figure 1 - Figure 2 shown, a locking device for the end cell cover plate of an aluminum electrolysis cell disclosed by the present invention includes a cell cover plate located at the tapping end and the flue end of the electrolysis cell. The cell cover plate includes a cover plate frame 1, a left cover plate 2 and a right cover plate 3 located on the cover plate frame 1. An "L"-shaped limiting plate 4 is hinged on the cover plate frame 1 above the closing seam of the left cover plate 2 and the right cover plate 3. The "L"-shaped limiting plate 4 rotates up and down to make room for the opening and closing of the cell cover plate or to limit the cell cover plate. With such a structure, by rotating the "L"-shaped limiting plate 4 upward, room can be made for the opening and closing of the cell cover plate. At the same time, after closing the cell cover plate, by rotating and lowering the "L"-shaped limiting plate 4, the "L"-shaped limiting plate 4 can limit the cell cover plate and prevent it from opening. In this way, the "L"-shaped limiting plate 4 is located above the cell cover plate and is not easily contacted with material handling equipment, etc. At the same time, its structure is an integral iron plate and is installed by means of hinging such as hinges. The structure is simple, durable, and easy to operate, suitable for the frequent opening and closing of the cell cover plate.

[0025] A heat insulation plate 5 is fixed on the electrolysis cell close to the cell cover plate, and a magnet 6 that cooperates with the "L"-shaped limiting plate 4 is provided on the isolation plate. The heat insulation plate 5 is connected to the electrolysis cell by means of welding, etc., and the magnet 6 is connected to the heat insulation plate 5 by means of bayonet connection or strong glue, etc. By means of the magnet 6, when opening the cell cover plate, the upwardly rotating "L"-shaped limiting plate 4 can be fixed in position, facilitating the subsequent closing of the cell cover plate.

[0026] Embodiment 2

[0027] As Figure 1 - Figure 2As shown in the figure, this embodiment is an improvement on the structure of the "L"-shaped limiting plate 4 based on Embodiment 1. Specifically, the "L"-shaped limiting plate 4 is provided with a closed seam shielding plate 7 connected to each other. Because the cover plate will be worn after long-term use, the closed seam will become larger and larger, posing a safety hazard to the production workers in the positive direction of the closed seam. Therefore, the closed seam can be shielded through the closed seam shielding plate 7. At the same time, compared with the method of reaching out and rotating the "L"-shaped limiting plate 4 in Embodiment 1, it is convenient for workers of various heights to rotate the "L"-shaped limiting plate 4 by lifting the closed seam shielding plate 7 to make space for the opening and closing groove cover plate. The inner side of the closed seam shielding plate 7 is provided with refractory cotton, which can play a certain heat insulation role. At the same time, a handle is provided on the "L"-shaped limiting plate 4 or the closed seam shielding plate 7. In this way, through the handle, it is convenient to pull open the closed seam shielding plate 7 or the "L"-shaped limiting plate 4, and it also avoids the safety hazard brought by direct contact with the closed seam shielding plate 7.

[0028] The above is only a preferred embodiment of the present invention, and it does not impose any form of confidentiality restriction on the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical content of the present invention and according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
