Abstract
The utility model discloses a detachable intermediate support device for an aluminum electrolytic cell shell and capable of preventing arch deformation. The structure of the device is that a supporting beam (2) on the upper part of the electrolytic cell is connected with a transverse beam (7); the transverse beam (7) is connected with an insulating intermediate support device (3); the intermediate support device (3) is connected with the electrolytic cell shell (5); the supporting beam (2) on the upper part of the electrolytic cell is connected with the transverse beam (7) through a short bearing (6); the supporting beam (2) on the upper part of the electrolytic cell is connected with the short bearing (6) through a coupling bolt (1); the short bearing (6) is connected with the transverse beam (7) through the coupling bolt (1); and the intermediate support device (3) is connected with the electrolytic cell shell (5) through a supporting column (4). Before roasting starts, the detachable intermediate support is arranged in the middle of the large-sized electrolytic cell and is used for inhibiting arch-up deformation of the electrolytic cell shell when roasting starts. The device is detachable, so the device can be detached during normal production, normal pole-exchanging operation of the electrolytic cell shell is not influenced, and the labor productivity of the electrolytic cell is greatly increased.
Description
Technical field
The utility model relates to a kind of supporting device that prevents aluminum cell casing arch distortion.
Background technology
Along with the develop rapidly of aluminum electrolyzation technology, large-scale aluminum electrolytic cell and super-huge aluminium cell are generally adopted in the electrolysis of aluminum engineering design.The capacity of aluminium cell increases; Cell construction all broadens elongated; Particularly the pot shell length dimension of electrolyzer is elongated; To cause electrolyzer in the roasting and starting process, to produce serious arch distortion, this serious arch distortion will cause serious damage to electrolytic liner, will cause the generation of electrolysis early damage and runout accident when serious.
Large-scale aluminum electrolytic cell was designed with two kinds of structures both at home and abroad in the past: first kind is the device that any anti-electrolyzer arch distortion is not installed, and these large-scale aluminum electrolytic cells operation arch distortion later on are serious, finally cause the generation of early stage runout accident.The ubiquitous phenomenon of the electrolyzer of this structure be two generation groove life-span poor, this should have direct relation with the cell lining damage that the serious arch of electrolyzer distortion causes.Second kind is on large-scale aluminum electrolytic cell, to adopt permanent intermediate supporting device to suppress the distortion of electrolyzer pot shell; And large-scale aluminum electrolytic cell generally adopts big face multiple spot to advance electricity owing to the needs of Magnetic Field Design, and permanent intermediate support and multiple spot advance the existence of electricity; Make the work of electrolyzer change poles extremely inconvenient; And electrolyzer arch distortion only takes place when roasting and starting, and the longest time, therefore permanent intermediate support only produced certain effect at the electrobath start initial stage also with regard to about 6 days; When the electrolyzer ordinary production, just there be not much having acted on; And electrolyzer average producing days in a time between overhaul reached more than 2000 days, that is to say that permanent intermediate support employed time in the whole life cycle of electrolyzer is very short; Therefore the arch that has solved electrolyzer in the short period of time that exists of permanent intermediate support is out of shape, but in long-time, has influenced the operation of electrolysis ordinary production.
Summary of the invention
The purpose of the utility model is: the removable intermediate supporting device of a kind of aluminum cell casing with anti-arch distortion is provided; This device can effectively prevent electrolyzer arch distortion; And has a removability; To overcome the aluminum cell casing arch distortion that prior art exists liner is caused serious damage, or permanent intermediate support influences deficiencies such as electrolysis ordinary production operation.
In order to solve described technical problem, the utility model is to constitute like this: the upper part of the electrolytic cell support beam is connected with crossbeam, and crossbeam is connected with the intermediate supporting device of tape insulation, and intermediate supporting device is connected with electrolytic bath shell.
The upper part of the electrolytic cell support beam is connected with crossbeam through short supporting.
The upper part of the electrolytic cell support beam is connected through joint bolt with crossbeam with short supporting, short supporting.
Intermediate supporting device is connected with electrolytic bath shell through pillar stiffener.
Large-scale aluminum electrolytic cell before roasting and starting, the arch of electrolyzer pot shell distortion when a removable intermediate support being set in the middle suppressing roasting and starting.This installs maximum characteristics is removability, therefore when ordinary production, can it be removed, thereby not influence the normal change poles operation of electrolyzer, has so just improved the labour productivity of electrolyzer greatly.
Description of drawings
The structural representation (only illustrating the part-structure of electrolyzer) that Fig. 1 installs at the large scale electrolytic cell middle part for the utility model;
Fig. 2 is A-A sectional view of Fig. 1.
Embodiment:
The embodiment of the utility model: the structure of the utility model is following: upper part of the electrolytic cell support beam 2 is connected with crossbeam 7, and crossbeam 7 is connected with the intermediate supporting device 3 of tape insulation, and intermediate supporting device 3 is connected with electrolytic bath shell 5.
Upper part of the electrolytic cell support beam 2 is connected with crossbeam 7 through short supporting 6.
Upper part of the electrolytic cell support beam 2 and short supporting 6, short supporting 6 are connected through joint bolt 1 with crossbeam 7.
Intermediate supporting device 3 is connected with electrolytic bath shell 5 through pillar stiffener 4.
During roasting and starting, adopt above-mentioned connection, can utilize the big weight of upper part of the electrolytic cell support beam 2 to overcome the arch distortion of electrolyzer.When ordinary production, joint bolt 1 is removed and can handling be walked this device, the change poles operation during with assurance electrolysis ordinary production.
Range of application: this utility model prevents the device of electrolyzer pot shell arch distortion in the time of can being used on the jumbo electrolyzer as roasting and starting.
Intermediate supporting device (3) physical dimension and shape all can be adjusted according to actual.
