Abstract
The utility model provides a coping device between the aluminum electrolyser cathode bar and the cathode soft belt, wherein the coping device is an L-shaped copper plate or other conductive plate, and a screw is drilled in one face of the plate and the bottom is connected with an aluminum plate. The coping device is simple in structure and convenient to operation without welding. Once installed, the coping device can be permanently used without being replaced during the repair of the electrolyser. The utility model solve the problem that the large-scale electrolyser can not be welded with the cathode bar because of the magnetic field, thereby reducing the pressure fall of the coping between the aluminum electrolyser cathode bar and the bus and reducing the consumption of the direct current when producing the aluminum ingot and the electric consumption of the products, further reducing the labor intensity and a good deal of the field welding during the field repair of the aluminum electrolyser, thereby lowing the producing and repairing costs.
Description
Technical field:
The utility model relates to the subassembly of a kind of electrolyzer and negative busbar, the connector presser between especially a kind of aluminum cell cathode steel bar and the soft band of negative electrode.
Background technology:
Continuous increase along with aluminium cell capacity and electric current, magneticstrength around the groove also sharply rises, when the electrolytic system electric current reaches 200KA when above, powerful magnetic field all can not be carried out all metal solder, in only take series to have a power failure during the 320KA Thoughs overhaul of aluminium Guangxi branch office the way welding, and the have a power failure way weld of series only could be used seldom the time in series of grooves, when series of grooves is a lot of because frequent power failure of series can be to production generation serious harm.And during electrolytic cell overhaul, it directly is to adopt the method for welding to connect that groove surrounding cathode rod iron is connected another with scene between the soft band of negative electrode.China is maximum in the world aluminium producing country, and therefore design recent years and the electrolytic cell currents built, solve that being connected between the cathode steel bar and bus is extremely urgent major issue under the high-intensity magnetic field condition all more than 240KA.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, need not welding, and is easy and simple to handle, the connector presser between the soft band of aluminum cell cathode steel bar that one-step installation can forever be used and negative electrode.
Technical solution adopted in the utility model is: connector presser is a L type copper coin or other conductive sheet metal, and it simultaneously is drilled with screw, and the lower end connects an aluminium sheet.
This connector presser is simple in structure, need not weld, and is easy to operate, just can permanently use on the one-step installation, do not need to change when groove overhaul again.Solved the difficult problem that large-scale groove does not weld cathode steel bar greatly owing to magnetic field.Reduce the crimping pressure drop between aluminum cell cathode steel bar and the bus, reduce aluminium ingot production consumption of direct current, reduced the product power consumption.Alleviated on-the-spot aluminium cell overhaul labour intensity, a large amount of site welding work when having reduced electrolytic cell overhaul reduces and produces and the overhaul cost.
Description of drawings:
Fig. 1 is this connector presser structural representation.
Fig. 2 is the side-view of Fig. 1.
Fig. 3 is for installing connection diagram.
Embodiment:
The utility model structure is seen Fig. 1.By a L type copper coin 1 or other conductive sheet metals of L type, its one side is being drilled with screw 2 (two or 4) with negative busbar correspondingly-sized place, and lower end and aluminium sheet 3 explosive weldings form.Also can take other mode of connection without explosive welding.
Connector presser II one end directly is connected with bolt with cathode steel bar termination I during installation, and the soft band of the other end and aluminium III (bus) adopts aluminium---and aluminium welding process (this weld has just been constructed when building, for nonvolatil) connects, and sees Fig. 3.Electrolytic cell currents is from the cathode steel bar I → soft band of connector presser II → aluminium III → next platform trough.When electrolytic cell overhaul, only need dismantle joint bolt cathode steel bar is separated with connector presser, after overhaul is intact, with bolt cathode steel bar is connected with connector presser again and get final product, not be subjected to the influence of external magnetic field, not need serial power failure operation.
