Thermal-insulation energy-saving environment-friendly aluminum electrolysis cell upper structure

Abstract

Movable heat preservation tank covers are symmetrically distributed on the two sides of a fixed heat preservation tank cover, the inner ends of the movable heat preservation tank covers are hinged to the fixed heat preservation tank cover through hinges, and the outer ends of the movable heat preservation tank covers are in lap joint with the upper edge of the electrolytic cell. The supporting plate is fixedly arranged right above the fixed heat preservation tank cover through the supporting columns, and the anode conductive rod penetrates through the fixed heat preservation tank cover in a sealed mode; the winch is fixedly installed on the supporting plate, one end of the steel wire rope is wound and connected to a winch of the winch, and the other end of the steel wire rope is fixedly connected to the movable heat preservation tank cover; the smoke inlet ends of the branch discharge flues penetrate through the fixed heat preservation tank cover in a sealed mode to be communicated with the interior of the electrolytic tank, the smoke discharge ends of the branch discharge flues are communicated with the main discharge flue, and the main discharge flue is fixedly arranged above the supporting plate; a crust breaking and discharging sealing pipe is vertically installed in the middle of the fixed heat preservation tank cover, the crust breaking and discharging machine is vertically arranged over the crust breaking and discharging sealing pipe, and a hammerhead rod of the crust breaking and discharging machine penetrates through the crust breaking and discharging sealing pipe and extends into the electrolytic tank.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolytic cells, and in particular relates to an upper structure of an aluminum electrolytic cell of thermal insulation, energy saving and environmental protection. Background technique [0002] For modern large-scale pre-baked aluminum electrolytic cells, pre-baked anodes are used. When the anode is consumed to a certain height, the anode needs to be replaced from the upper part of the aluminum electrolytic cell, but the traditional upper structure of the aluminum electrolytic cell will replace the anode. bring inconvenience. In addition, the upper structure of the traditional aluminum electrolytic cell has the problem of poor thermal insulation effect, and the heat dissipation of the aluminum electrolytic cell is large during operation, resulting in high energy consumption. Furthermore, the upper structure of the traditional aluminum electrolytic cell has the problem of fugitive emission of...
