权利要求

1. In an electrolytic cell for the production of aluminum, a structure comprising a trough-shaped container having an upper open end and being adapted to contain an electrolyte; an anode extending with a portion thereof into the electrolyte and having an upper portion above the latter; and closed, heat-insulated housing means covering said open end of said container and surrounding said upper portion of said anode to maintain about the latter a confined volume of air to thereby reduce heat radiation from said anode to the surrounding atmosphere, said housing means comprising rigid frame means, a front and a rear wall fixed to said frame means, and a roof movable between a closed position closing the upper end of said housing means and an open position providing access to the interior of said housing means for insertion of anodes thereinto.

2. A structure as defined in claim 1, and including substantially horizontal guide rail means fixed to and forming part of said frame means for guiding said roof movable between said closed and a laterally displaced open position, and drive means connected to said housing for moving the same along said guide rail means between said positions thereof.

3. A structure as defined in claim 1, wherein said housing means comprises further a pair of opposite side wall means each including movable portions and additional opposite guide rail means forming part of said frame means for guiding said movable portions between an open and a closed position.

4. A structure as defined in claim 3, wherein said additional opposite guide rail means are inclined toward each other and wherein each of said opposite side wall means comprises a pair of vertically displaced and partly overlapping movable portions, drive means connected to the lower one of said vertically displaced portions and means connected to the lower edge of said lower portion and engaging the lower edge of the upper portion during raising of the lower portion by the drive means to thereby raise also said upper portion.

5. A structure as defined in claim 4, and including sealing means at least along upper and lower edges of said movable portions of said side wall means.

6. A structure as defined in claim 2, wherein said roof has a lower edge and including cooperating sealing means on said frame means and on said lower edge of said roof.

7. A structure as defined in claim 6, wherein said cooperating sealing means comprise a U-shaped member into which said lower edge of said roof extends, and wherein said drive means includes lifting means for slightly lifting said roof to thereby lift said lower edge out of said U-shaped member before moving said roof laterally to its open position.

8. A structure as defined in claim 3, and including heat insulation on the walls and the roof of said housing means.
