Description

An aluminum electrolytic cell cover system and an aluminum electrolytic cell device including a cover-moving mechanism

technical field

The invention relates to the field of aluminum production, in particular to an aluminum electrolytic tank cover system and an aluminum electrolytic tank device including a cover moving mechanism.

Background technique

At present, metal aluminum is obtained by cryolite-alumina molten salt electrolysis method. Due to the particularity of the production process, a large amount of dust and electrolysis flue gas (CO ₂ , HF gas, SO _{2 ,} etc.) escape from the electrolytic cell during the electrolysis process. , causing pollution to the production workshop and the surrounding environment. In order to reduce pollution and purify the production environment, a tank cover is set on the electrolytic cell to prevent dust and smoke from escaping. The tank cover plates are placed and covered in series on the electrolytic cell, and each piece can be manually opened, closed and removed independently. The tank cover plates have the functions of preventing pollutants from escaping, maintaining the negative pressure balance of gas collection in the tank, and preventing foreign objects from falling into the tank. In the tank, to protect the safety of personnel in the workplace, and to keep the tank warm.

At present, the opening and closing tank cover plates are manually operated by on-site operators. In order to facilitate the operation of the operators, the side tank cover plates of the electrolytic cell are usually designed as light and thin aluminum sheets. There are mechanical Problems such as low strength and large heat loss.

In the production process, in order to facilitate the operation (screw the anode fixture, overhaul the upper device of the tank, etc.), the operator often steps on the tank cover plate, and the low mechanical strength often leads to mechanical deformation of the cover plate. In addition, due to mechanical strength, the deformed cover plates usually have large gaps at the joints of each other, resulting in poor airtightness; a large amount of ambient air enters the electrolytic cell through the gap, which increases the energy loss and smoke of the electrolytic cell. Air purification system processing load. In order to ensure a certain airtight effect during production, the way of regularly replacing the cover plate is usually adopted (the service life of the cover plate is usually 2 to 3 years).

Compared with the tank cover with insulation material, the surface temperature difference of the thin aluminum tank cover can reach 30°C, which is not conducive to the insulation of the electrolytic tank; on the other hand, long-term high-temperature heat radiation is easy to cause harm to the operators.

Although high-strength or insulation-added trough cover panels have also been developed at present, it is difficult to be manually opened and closed by operators due to the obvious increase in weight. If a lifting device is used for opening and closing, there will be problems such as positioning difficulties and swinging after lifting, which have not yet been resolved.

In order to be able to use high strength, high thermal insulation and high weight coffer panels, there is a need for an improved coffer panel system that can be opened and closed accurately and easily.
