It is of great significance.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of sealing cover plate of aluminium cell
Structure is set close to electrolytic bath along plate including aluminium sash and the cover plate in cabochon being securedly mounted on aluminium sash
Several heat bulges towards outside arcwall face are integrally convexly equipped in the plate face for the cover plate on aluminium sash set.
As a preferred embodiment, the heat bulge is strip bulge disposed in parallel, the strip bulge
Length direction or width direction along the cover plate extend.
As a preferred embodiment, the strip bulge extends along the width direction of the cover plate.
As a preferred embodiment, the section of the strip bulge is semicircle or triangle.
As a preferred embodiment, the section of the strip bulge is triangle, position in adjacent two strip bulge
The bottom surface of the top surface of strip bulge under the resting against strip bulge top with position connects.
The beneficial effects of the utility model are: the sealing cover plate structure of aluminium cell provided by the utility model, by
One projection is several towards outside arcwall face in the plate face of arc cover plate of the electrolytic bath on the aluminium sash that plate be arranged
Protrusion, increase the plate suqare of arc cover plate herein, therefore increase the radiating surface of cover plate herein, reached raising close to slot
Along the effect of the specific heat load of the high-temperature region of plate part.By increasing close to slot along the surface of the cover plate of plate (high-temperature region) part
Product, increases specific heat load, assistant reinforcement furnace helps the heat dissipation in portion, finally plays the mesh of the balanced above degree of heat radiation of anode shell surface
, it is of great significance to forming firm furnace side, guarantee electrolytic cell steady production and improving groove life.
Meanwhile solving the problems, such as the long-term hot-spot of sealing cover plate, it ensure that the heat preservation and sealing of sealing cover plate
Effect.
