Description

Technical Field

[0001] The utility model relates to an aluminum fluoride self-adding device for electrolytic aluminum, belonging to the technical field of auxiliary tools for electrolytic aluminum production. Background Art

[0002] In the actual production of electrolytic aluminum, in order to maintain efficient, long-term and stable operation, the electrolytic cell needs a moderate superheat to reduce the melting point and increase the conductivity of the electrolyte, so aluminum fluoride needs to be added regularly. The traditional method of adding aluminum fluoride is to cut the package manually, and add the flow material by facing the cut end to the feed port of the tank. This method has the following shortcomings: first, it is not convenient and fast enough; second, it increases the labor intensity of workers and poses safety hazards; third, the large package cannot be closed after being cut, which easily causes material waste and flying everywhere, increases the production cost of a ton of aluminum and is not conducive to environmental protection development. In the long run, it may seriously increase the cost of a ton of aluminum for electrolytic aluminum production enterprises, pollute the surrounding environment, and have an adverse effect on the stable and efficient production of electrolytic cells. Utility Model Content

[0004] The technical solutions adopted by the utility model to solve the technical problems are as follows:

[0005] An autonomous aluminum fluoride adding device for electrolytic aluminum comprises a material box main structure and a cone structure, wherein the material box main structure is a rectangular parallelepiped, and the cone structure is a funnel-shaped quadrangular pyramid, the material box main structure and the cone structure are welded into an integrated structure, an anti-flying feeding net is arranged in the middle and upper part of the material box main structure, four crane hoisting hooks are evenly arranged on the top around the material box main structure, a cone discharge port is arranged at the bottom of the cone structure at the center, upper and lower movable steel bars are penetrated through the upper part of the cone discharge port, the diameter of the movable steel bars matches the diameter of the bottom of the cone discharge port, and when the movable steel bars drop due to gravity, they just block the discharge port to stop discharging.

[0006] A transparent observation port is provided on the side of the main structure of the material box, so that the material level of the material box can be observed at any time; reinforced handrails are welded on both sides of the main structure of the material box to facilitate the movement or transportation of the device.

[0007] Support devices are arranged around the main structure of the material box and the cone structure, and the main structure of the material box and the cone structure are placed in the support devices for firm support. The support device is a rectangular parallelepiped structure welded by eight horizontal reinforcing ribs and four vertical reinforcing ribs, and four movable pulleys are installed at the bottom of the four vertical reinforcing ribs, which pull the reinforced handrails and thus drive the entire device to move or transport.

The aluminum fluoride accumulated at the bottom of the cone structure flows from the gaps on both sides of the movable steel bars to the trough material box, thereby achieving the purpose of adding aluminum fluoride.

[0013] After the feeding is completed, the utility model is slowly lifted up by a hoisting crane, and the upper and lower movable steel bars sink to the conical discharge port under the action of gravity. Because the diameter of the movable steel bars matches the diameter of the bottom of the conical discharge port, when the movable steel bars drop due to gravity, they just block the discharge port, perfectly closing it, and the discharge is completed.

[0028] Example: See Figure 1 to Figure 4A self-feeding device for aluminum electrolysis includes a material box main structure 1 and a cone structure 2. The material box main structure 1 is a rectangular parallelepiped, and the cone structure 2 is a funnel-shaped quadrangular pyramid. The material box main structure 1 and the cone structure 2 are welded into an integrated structure. An anti-flying feeding net 5 is arranged in the middle and upper part of the material box main structure 1. Four crane hoisting hooks 4 are evenly arranged on the top around the material box main structure 1. A cone-shaped discharge port 10 is arranged at the bottom of the center position of the cone structure 2. Up and down movable steel bars 8 are penetrated in the upper part of the cone-shaped discharge port 10. The diameter of the movable steel bar 8 matches the diameter of the bottom of the cone-shaped discharge port 10. When the movable steel bar 8 drops due to gravity, it just blocks the outlet of the cone-shaped discharge port to stop discharging.

[0029] A transparent observation port 3 is provided on the side of the material box main structure 1, so that the material level of the material box can be observed at any time; reinforced handrails 6 are welded on both sides of the material box main structure 1 to facilitate the movement or transportation of the device.

[0030] A supporting device 7 is arranged around the main structure 1 of the material box and the cone structure 2. The main structure 1 of the material box and the cone structure 2 are placed in the supporting device 7 for firm support. The supporting device 7 is a rectangular parallelepiped structure welded by eight horizontal reinforcing ribs and four vertical reinforcing ribs. Four movable pulleys 9 are installed at the bottom of the four vertical reinforcing ribs, which pull the reinforced handrails 6 and drive the entire device to move or transport.

[0031] The material box main structure 1 and the cone structure 2 are both made of high-strength steel plates, which have the characteristics of high hardness and not easy to be damaged.

[0032] The eight horizontal reinforcement bars and the four vertical reinforcement bars are all high-strength steel bars with strong load-bearing capacity and not easy to deform and break. The eight horizontal reinforcement bars are arranged in two rows, with one bar on each side of each row, providing effective support.

[0033] The 5 holes of the anti-flying feeding net are small and dense, which can not only filter out large particles of impurities, but also effectively prevent materials from flying around.

[0034] The aluminum fluoride bag is discharged and added from the upper part of the anti-flying material net 5 and reaches the conical discharge port 10 of the cone structure 2 through the material box main structure 1.

[0035] When adding materials, a lifting crane is used to lift the utility model to the top of the trough material box through the lifting hook 4, and the utility model is slowly lowered. At this time, the upper and lower movable steel bars 8 are placed on the top of the trough material box (receiving box) and automatically move to the top of the conical discharge port 10. The aluminum fluoride accumulated at the bottom of the cone structure flows from the gaps on both sides of the movable steel bars to the trough material box, thereby achieving the purpose of adding aluminum fluoride.

[0036] After the feeding is completed, the utility model is slowly lifted up by a hoisting crane, and the upper and lower movable steel bars 8 sink to the conical discharge port 10 under the action of gravity. Because the diameter of the movable steel bars 8 matches the diameter of the bottom of the conical discharge port 10, when the movable steel bars 8 drop due to gravity, they just block the discharge port, perfectly closing it, and the discharge is completed.
