Abstract
The utility model provides a device for preventing the upper end of a shell of an electrolytic tank from deforming, and aims to solve the following problems that since a middle support which is adopted in the 500KA aluminum electrolysis series for solving the arching deformation of the shell in the case of start of the electrolytic tank at present, electrolytic production operation is very inconvenient, and since no measure is taken for below 500KA electrolysis series, the service life of the electrolytic tank is affected, and for worse, early damage can be caused to result in stopping, and at present, counterweights which are arranged at the two ends of the shell of the electrolytic tank for upwarping deformation of the two ends of the shell at the stop of the electrolytic tank are capable of affecting the oven building operation. The device comprises a rod, support seats and nuts, wherein through holes are formed in the support seats; each of the two ends of the rod penetrates through the through hole on one support seat; the two ends of the rod both are provided with screw threads; and the nuts are arranged on the rod at the two sides of each support seat, respectively. The device is used for electrolytic production.
Description
Technical field
The utility model relates to a kind of device that prevents pot shell distortion, belongs to electrolysis production field.
Background technology
How extending the life-span of electrolyzer, is one of problem of being concerned about most of design and production.Main and the design of life-span of electrolyzer, production, material, brickwork quality are closely related.
Electrolyzer is when roasting and starting, pot shell is because the upper and lower temperature difference is larger, be that upper temp is high, temperature of lower is low, existence due to the temperature difference, top exists larger to external stress, make pot shell when roasting and starting, produce arch distortion, general all within the scope of 30-60mm, serious reach 100mm more than.This arch distortion, makes cell lining form crackle, affects the life-span of electrolyzer, when serious, formation early damage is stopped to groove.Electrolyzer is when stopping groove, also be because the upper and lower temperature difference of pot shell is larger, upper temp is high, temperature of lower is low, is stopping groove when cooling, and top is shunk and made soon pot shell two ends upwarp when distortion Te Do is overhaul to exclude liner and remove after superstructure, be out of shape even more serious, general all at 30-60mm, serious will reach 100mm more than.Because most of electrolytic series in Country is online overhaul, cannot repair pot shell two ends and upwarp distortion, therefore exhausted most aluminium manufacturer two generations groove is not repaired because two ends upwarp distortion, form early damage and stop groove or affect two generation cell life.
In the past for the arch distortion of electrobath start pot shell and stop groove two ends and upwarp the form that distortion Bian uses and be: the pot shell arch distortion during for electrobath start, only in permanent intermediate strut or interim intermediate strut technology for 500KA electrolysis series Bian, and adopt above-mentioned technology, because being positioned at anode electrolytic cell side by permanent intermediate strut or interim intermediate strut, bring great inconvenience to the operation of electrolysis production change poles, while is because of the existence of intermediate strut, affect electrolytic tank hood keying, thereby affect the gas collecting efficiency of electrolyzer.But the following electrolytic aluminium factory Jun of 500kA No has any measure of Bian, and the existence of this distortion affects the life-span of electrolyzer, when serious, formation early damage is stopped to groove.While stopping groove for electrolyzer, pot shell two ends upwarp distortion, and some electrolytic aluminium factory Bian is used in the methods such as two ends ballast, because weight is placed on electrolytic bath shell two ends tops, have affected hanging in and hanging out and the brickwork operation of electrolyzer of electrolysis plow stove and brickwork material material.
Summary of the invention
The purpose of this utility model is: a kind of device that prevents the distortion of pot shell upper end is provided, to address the problem: existing pot shell arch distortion during for electrobath start, 500KA electrolysis series Bian also affects electrolytic tank hood when operation brings great inconvenience to change poles by intermediate strut and opens and closes, thereby affect the gas collecting efficiency of electrolyzer, the following electrolysis Xi of 500kA Lie No has any measure of Bian, affect the life-span of electrolyzer, when serious, formation early damage is stopped to groove; Existing while stopping groove for electrolyzer pot shell two ends upwarp distortion, in the method for pot shell two ends ballast, affect hanging in and hanging out and the brickwork operation of electrolyzer of electrolysis plow stove and brickwork material material.
Scheme of the present utility model is as follows: a kind of device that prevents the distortion of pot shell upper end, described device comprises bar, bearing and nut, on bearing, be provided with through hole, the two ends of bar are respectively through the through hole on a bearing, the two ends of bar are provided with screw thread, and the both sides that are positioned at each bearing on bar are provided with a nut respectively.
Described bar is steel pipe or rod iron.
The utility model compared with prior art, major advantage is as follows: the bearing at the bar two ends on device described in the utility model is fixed on to the upper end of described side along the length direction of pot shell side, after being so arranged on pot shell, when in the time of can effectively preventing electrobath start, pot shell arch distortion and electrolyzer stop groove, pot shell two ends upwarp distortion.Zhen Dui Xian You No has the following electrolysis series of 500kA of any preventing deformation measure for Bian, in the life-span of having improved electrolyzer, prevents that electrolyzer from stopping groove because of early damage; 500KA electrolysis series for Bian by intermediate strut, operation brings great inconvenience to change poles to have avoided intermediate strut, and affects electrolytic tank hood keying, and then affects the problem of the gas collecting efficiency of electrolyzer; For existing when pot shell two ends ballast prevents electrolyzer to stop groove pot shell two ends upwarp the method for distortion, avoided pot shell two ends weight to affect hanging in and hanging out and the problem of the brickwork operation of electrolyzer of electrolysis plow stove and brickwork material material.
