A temperature-adjusting and anti-deformation structure for aluminum electrolytic cell shell

Abstract

The invention discloses a temperature-regulating and deformation-preventing structure for an aluminum electrolysis cell shell. The temperature-regulating and deformation-preventing structure for the aluminum electrolysis cell shell is characterized in that a large-faced side plate and a small-faced side plate of the aluminum electrolysis cell shell are respectively formed by dual-layer side plates with inner-side flat plates and outer-side corrugated plates; compressed air pipelines with quick couplings are arranged in hollow regions formed by the corresponding inner-side flat plates and the corresponding outer-side corrugated plates, and can be connected with a main compressed air pipe of a workshop by virtue of joints. According to the temperature-regulating and deformation-preventing structure, the purpose that the temperatures of the side plates of the cell shell are regulated in real time is achieved, and the outward-arching deformation of the large-faced side plate and the small-faced side plate of the cell shell can be controlled; the temperature-regulating and deformation-preventing structure is simple and easy to realize, and facilitates stable and safe production of an electrolysis cell, improvement of the labor efficiency and prolonging of the service life of the aluminum electrolysis cell shell.

Description

technical field [0001] The invention relates to a temperature-adjusting and deformation-resistant structure for an aluminum electrolytic tank shell, which is characterized in that the large side plate and the small side plate of the tank shell adopt a double-layer side plate structure, and belongs to the technical field of aluminum electrolytic equipment. Background technique [0002] With the increasing size of aluminum electrolytic cells, in the entire production cycle from roasting start to overhaul of the cell shell, controlling the reasonable temperature of the side plate of the cell shell is a necessary condition for forming a regular furnace side and a stable cathode heat balance system, and is essential for extending the Tank life plays a key role. [0003] On the one hand, due to the dynamic changes of various working conditions in production, it is necessary to adjust the temperature of the side plate of the tank shell by time period, area and intensity in order to...
