Folding-fan-type cell cover plate of aluminum electrolytic cell

Abstract

The invention discloses a folding-fan-type cell cover plate of an aluminum electrolytic cell. The cell cover plate comprises a corner cell cover, a ladder stand, an upper track, a lower track and a large face cell cover. The corner cell cover is arranged at the end of the electrolytic cell. The ladder stand is arranged on the side end, close to a flue, of the electrolytic cell. The upper track is located on the cell edge of the upper portion of the electrolytic cell. The lower track is located on the cell edge of the lower portion of the electrolytic cell and parallel to the upper track. The large face cell cover is arranged on the electrolytic cell and slides along the upper track and the lower track. The large face cell cover comprises multiple pairs of aluminum square tubes, each pair of the aluminum square tubes is of a folding-fan structure, and every two adjacent pairs of the aluminum square tubes are connected through strong magnets. Fixing shafts are fixed at the ends of the aluminum square tubes, rollers are mounted on the fixing shaft, and the large face cell cover moves on the upper track and the lower track through the roller. The heat preservation sealing and the tread function are separated, and the cell cover plate further has the advantages of lightweight, low cost, low operation labor intensity, good heat insulation effect and excellent airtight performance.

Description

Technical field [0001] The invention belongs to the non-ferrous metal smelting industry, belongs to the technical field of aluminum electrolysis equipment, and particularly relates to a fan-type aluminum electrolysis tank cover plate. Background technique [0002] At present, the functions realized by the aluminum electrolytic cell cover plate in the prior art mainly include: 1) airtight function to prevent the flue gas in the tank from leaking out and outside cold air to enter; 2) heat preservation and heat insulation to reduce the heat loss of the electrolytic cell, Improve current efficiency; 3) Support the pedaling effect, which is convenient for the operator to carry out the tightening of the small box clamp, inspection and maintenance of the upper mechanism, etc. Since the prior art integrates the support and pedaling function on the trough cover, each large trough cover must have sufficient strength and rigidity, resulting in a large amount of material for the trough cover...

AI Technical Summary

Problems solved by technology

Because the existing technology integrates the function of supporting and stepping on the slot cover, each large-face slot cover must have sufficient strength and rigidity, resulting in a large amount of material for the slot cover and high cost; in addition, opening and closing the slot cover It is usually carried by the operator, resulting in high labor intensity; at the same time, the trough cover is often transported, and it is inevitable that it will not be bumped, and it will bear the pedaling force, which will easily cause deformation and damage of the trough cover, affecting its airtightness and life, and requires irregular maintenance.
