The lower end of dynamic heat preservation tank cover is placed in the pot shell inner side of cell body groove bottom, is placed on the side wall carbon block of groove bottom, by dust removing cloth
Bag or coating charcoal clay etc. are sealed, so that selectivity as needed carries out new, old moving thermal insulation groove cover and anode carbon block
Change in the lump, hang shifting.
The heat-preserving cover plate include horizontal metal plate, the one layer of heat preservation brick being sequentially arranged on the downside of horizontal metal plate and one layer it is resistance to
Firebrick.
Hoisting ring is set on the moving thermal insulation groove cover, heat-preserving cover plate, shifting is hung with fast and easy.
The connection heat-preserving cover plate is I-steel with the connector of gas skirt, and the lower end of I-steel is fixed in heat-preserving cover plate
Side, the lower surface of I-steel is sequentially provided with heat-insulation layer and flame retardant coating, and the upper end of I-steel is placed in heat-preserving cover plate top, and is fixed on
On gas skirt lower surface, it is fixed on the tremie pipe lower end in the middle part of gas skirt and is placed in cell body through I-steel.
The tremie pipe is a VERTICAL TUBE with cavity, and the upper and lower end of VERTICAL TUBE is opened wide, on the pipeline section in gas skirt
The blast pipe and feed pipe connected with cavity are respectively equipped with, the blast pipe other end is opened wide, is placed in gas skirt, and feed pipe is another
End is connected through gas skirt with hopper, so that the gas produced in electrolysis production directly enters gas skirt through VERTICAL TUBE, blast pipe
Afterwards, then by the pipeline being connected with gas skirt discharge, while the alumina powder in being easy to hopper is straight through feed pipe, VERTICAL TUBE
Pick electrolysis in electrolytic cell.
The present invention has following advantages and effect compared with prior art：Using such scheme, it is convenient to which using can be quick
The movable heat insulation cover of replacing replaces the insulation mulch such as aluminum oxide, face-piece block and electrolyte block of prior art, without frequent again
Addition insulation material, replacing anode carbon block is convenient, fast, effectively reduces labour intensity, improves operating efficiency, while reducing heat waste
Lose, fundamentally avoid insulation mulch and fallen into electrolytic cell in anode change and insulation material addition operation process, and break
Bad electrolytic cell heat balance and mass balance；And during anode carbon block replacing, transport and pressure-off, no longer there is insulation mulch
Fly upward and splash, environmental benefit can be increased substantially, reduce ton aluminium material consumption；Under the large-scale pre-baked burning aluminium cell of solution is only therefrom stitched
Material, the problem that aluminum oxide can not rapidly dissolve, spread, it is ensured that the steady Effec-tive Function of electrolysis production.
The present invention suitably all preroast aluminium cell productions, are particularly well-suited to the production of large-scale pre-baked burning aluminium cell,
Thoroughly solve large pre-baked cell production anode change labour intensity big, material balance and thermal balance destruction are tight during anode change
Weight, the problem that heat loss is larger, ton aluminium material consumption is big and environmental benefit is poor, significantly improve aluminium electroloysis economic and technical norms and environment
Benefit, and labour intensity is greatly lowered.
