Abstract
Description
Technical Field
[0001] This utility model relates to an electrolytic cell maintenance and protection device, and particularly to a safety protection device for an aluminum electrolysis workshop, belonging to the field of aluminum electrolysis technology. Background Technology
[0002] Maintenance of the upper part of the electrolytic cell is crucial for production safety, efficiency, and equipment lifespan. Workers need to regularly inspect the upper part of the electrolytic cell to promptly detect problems such as corrosion, insulation damage, and aging wiring, preventing short circuits or abnormal high temperatures caused by poor contact. During maintenance work on the upper part of the electrolytic cell, due to its high position, workers often need to use the cell's sealing plate for operation. However, the temperature inside the electrolytic cell is extremely high, and over long-term use, the plate may collapse due to corrosion or insufficient load-bearing capacity, posing a safety hazard. Furthermore, workers stepping on the plate can damage precision components such as instruments and pipelines. Utility Model Content

[0005] A safety protection device for an aluminum electrolysis workshop includes L-shaped positioning frames and ladders. There are four L-shaped positioning frames, which are respectively set on both sides of the furnace door. A positioning groove is provided between the bottom of two L-shaped positioning frames on each side. A support block is provided on the top of the L-shaped positioning frame, and a support column is provided between two support blocks on each side. A ladder is provided between the support column and the positioning groove. Handles are provided on both sides of the ladder, and anti-slip ribs are provided on the outer surface of the ladder.
[0006] The outer wall of the L-shaped positioning frame is fixedly connected to the side of the furnace door.
[0007] The top of the ladder plate is provided with a hook plate, and the bottom of the ladder plate is provided with an insert plate, the size of which matches the size of the positioning groove.
[0008] The hook plate is erected on the support column.
[0009] The anti-slip ribs are at least six in number and are arranged vertically on the outside of the ladder board.
[0010] The L-shaped positioning frame, positioning groove, support block, ladder plate, hook plate, insert plate, handle, and anti-slip rib are all made of high-temperature resistant insulating materials.
[0011] The positive and beneficial effects of this utility model are:
[0012] 1. This utility model provides L-shaped positioning frames on both sides of the furnace door, with support columns and positioning grooves at the top and bottom of the L-shaped positioning frames, which facilitates the fixing of the ladder and ensures the stability of construction. Handles are provided on both sides of the ladder, and anti-slip ribs are provided on the outer surface of the ladder, which facilitates workers' climbing and makes it easier for workers to carry out maintenance and construction on the upper part of the groove.
[0013] 2. This utility model sets a ladder plate on the outside of the groove sealing plate, forming a high-temperature resistant insulating plate on top of the groove sealing plate. It has a good protective effect, avoiding the safety hazards of direct contact between workers and the groove sealing plate, which may cause damage to the groove sealing plate or burns to workers due to high temperature. It also improves the service life of the equipment and ensures the safety of construction. Attached Figure Description

[0018] See the example. Figures 1-3 A safety protection device for an aluminum electrolysis workshop includes an L-shaped positioning frame 1 and a ladder plate 5. There are four L-shaped positioning frames 1, which are respectively set on both sides of the furnace door A. A positioning groove 2 is set between the bottom of two L-shaped positioning frames 1 on each side. A support block 3 is set on the top of the L-shaped positioning frame 1, and a support column 4 is set between two support blocks 3 on each side. A ladder plate 5 is set between the support column 4 and the positioning groove 2. Handles 8 are set on both sides of the ladder plate 5, and anti-slip ribs 9 are set on the outer surface of the ladder plate 5.
[0019] The outer wall of the L-shaped positioning frame 1 is fixedly connected to the side of the furnace door A.
[0020] A hook plate 6 is provided at the top of the ladder plate 5, and an insert plate 7 is provided at the bottom of the ladder plate 5. The size of the insert plate 7 matches the size of the positioning groove 2.
[0021] Hook plate 6 is erected on support column 4.
[0022] There are at least six anti-slip ribs 9, which are arranged vertically on the outer surface of the ladder board 5.
[0023] The L-shaped positioning frame 1, positioning groove 2, support block 3, support column 4, ladder plate 5, hook plate 6, insert plate 7, handle 8, and anti-slip rib 9 are all made of high-temperature resistant insulating materials.
[0024] Support 4 is located above the groove sealing plate.
[0025] The ladder plate 5 is located outside the groove sealing plate.
[0026] In the above description, two L-shaped positioning frames are respectively set on both sides of the electrolytic cell.
[0027] In the above description, the positioning groove is located on the outer side of the bottom of the groove sealing plate.

[0030] Working principle:
[0031] When in use, the position of the ladder board can be freely adjusted according to the construction location, and the hook plate is fastened to the support and the insert plate is inserted into the positioning groove. Then, one worker holds the ladder board at the bottom while another worker climbs up the ladder board and carries out maintenance work on the upper part of the groove.
[0032] This utility model, by setting a ladder plate on the outside of the groove sealing plate and installing handles and anti-slip ribs on the ladder plate, not only facilitates workers to climb to the top of the groove for inspection and construction, but also avoids the safety hazards of workers being burned or the groove plate being deformed due to direct contact with the groove sealing plate, thereby improving the service life of the equipment, ensuring the safety of construction, and being easy to promote.
