Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis cell technology, and in particular to a ramming material filling device for aluminum electrolysis cells. Background Technology

[0002] Electrolytic cells are crucial equipment in the electrolytic aluminum metallurgical industry. When their various indicators fail to meet standards or maintenance becomes difficult, regular repairs of the cell lining are necessary. The final two processes in electrolytic cell furnace construction—filling with ramming material and welding the side plates—play a critical role in preventing furnace leaks. These processes prevent electrolytes from seeping through the gaps in the ramming material or flowing behind the silicon nitride side blocks and leaking out through the steel bar opening, thus causing leaks. In particular, improving the quality of the ramming material filling is decisive for repairing damage and extending the service life of the electrolytic cell. Traditional ramming material filling methods do not meet the actual requirements of the site and have the following problems:

[0003] 1. Low efficiency: Without changing the tamping tools, it takes 3 hours to tamp the material in one tank;

[0004] 2. Unstable quality: Inconvenient tools make it difficult to ensure tamping force and compaction during manual operation, affecting the filling quality of the tamping material;

[0005] 3. High labor intensity: Manual tamping requires a lot of physical strength, and the workers suffer from high labor intensity. It takes 3 hours to work on one trench, and blisters can be formed every time the workers work, making the construction workers suffer.

[0006] 4. Safety hazards: Manual operation poses certain safety hazards, such as the original wooden planks slipping and easily injuring the hands;

[0007] 5. Inadequate tools: There were no suitable tools, only a wooden board without sharp edges, which was inserted at an angle into the gap of the electrolytic cell. This was not scientific, and the force output by the construction workers was dispersed, the horizontal force was reduced, and the tamping material was not compacted, which seriously affected the quality of furnace construction. Because of the unscientific tools, the construction workers' hands were always blistered when tamping the material, so they did not want to do this process. As a result, the construction workers were not stable, and the construction quality was inconsistent. Utility Model Content

[0008] The purpose of this invention is to provide a ramming material filling device for aluminum electrolytic cells, thereby solving the problems mentioned above.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] This utility model discloses a tamping material filling device for an aluminum electrolytic cell, comprising a storage hopper installation mechanism mounted on a cell edge plate. The storage hopper installation mechanism includes a feeding and construction platform. The feeding and construction platform has baffles integrally formed on its front and rear sides. The front end of the baffles has an integrally formed fixing frame mounted on the cell edge plate. The feeding and construction platform has a matching tamping material operating mechanism. The tamping material operating mechanism includes a tamping support plate. The front end of the tamping support plate is provided with a tamping head. The upper rear surface of the tamping support plate is provided with a tamping handle. A protective plate is provided on the upper surface of the tamping support plate in front of the tamping handle.

[0011] Furthermore, the connection between the fixing frame and the baffle plate is aligned with the side brick.

[0012] Furthermore, the bottom of the fixing frame is aligned with the groove edge plate.

[0013] Furthermore, the height of the tamping head is less than the width of the gap between the electrolytic cell and the side bricks.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] The innovative design of the tamping material filling device for aluminum electrolytic cells ensures that the force output by the worker is not dispersed but directly applied horizontally to the tamping material, making the operation more convenient for construction personnel, significantly improving tamping efficiency, and greatly shortening construction time. Workers can determine the point and direction of force application by holding the tamping handle and tamping along the storage hopper, improving the material's density, thus ensuring tamping quality and extending its service life. The protective plate design eliminates the safety hazards associated with traditional tools, effectively protecting the safety of operators. Attached Figure Description
