Description
Technical field
The invention belongs to aluminum electrolysis technology field, particularly the device of anodic current shunting during a kind of roasting aluminum electrolytic bath.
Background technology
Pre-calcining electrolytic cell is in roasting process, because anode shape, the burnt grain of laying, the extension utmost point etc. cause, anodic current is concentrated, Current distribution in anode is bigger than normal, steel pawl, anode explosive welding, girder steel etc. are rubescent, when more serious, there is the de-utmost point, cause electrolyzer normally to start, when serious, when starting, there is a chain of de-utmost point, be forced to stop start, cause the accident, increase labor capacity.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the device of anodic current shunting while the object of the present invention is to provide a kind of roasting aluminum electrolytic bath, anode bias current problem while having solved calcination, guaranteed safety when calcination starts, improved the homogeneity that anode electrolytic cell distributes, solved bight anodic current less than normal, the problem that maturing temperature is on the low side, has improved bight maturing temperature.
To achieve these goals, the technical solution used in the present invention is:
The device of anodic current shunting during a kind of roasting aluminum electrolytic bath, comprise soft aluminium strip 2, one end of soft aluminium strip 2 connects one end of the first U-shaped card 31, the another end of soft aluminium strip 2 connects one end of the second U-shaped card 32, two anode rods are separately positioned in the first U-shaped card 31 and the second U-shaped card 32, the another end that the another end of the first U-shaped card 31 is provided with for the U-shaped card 32 of the first bolt 11, the second of fixed anode guide rod is provided with the second bolt 12 for fixed anode guide rod.
Described the first U-shaped card 31 and the second U-shaped card 32 are stainless steel.
Compared with prior art, the invention has the beneficial effects as follows:
1, this device adopts austenitic stainless steel material to make, and austenitic stainless steel thermal conductivity is low, and resistance to elevated temperatures is strong, is unique stainless steel of not having magnetic, therefore can not be subject to magneticinterference.
2, this device making is simple in structure, easy for installation, and handiness is good, practical.
When 3, the device of anodic current shunting is according to calcination during roasting aluminum electrolytic bath, Current distribution in anode is inhomogeneous, bight electrode current is less than normal, the features such as maturing temperature is inhomogeneous are made, with strong points, shunting effect is obvious, can really play current distributing effect, in the time of effectively controlling electrolysis roasting, Current distribution in anode is even.
The homogeneity of anodic current issue when 3, this device can improve calcination greatly, has reduced the probability that the de-utmost point occurs in anode bias current, and personnel's security risk while having improved electrobath start, provides a kind of safety control to operator.
