At present, domestic have many Aluminium Electrolysis factory to use this technology of starting mixture roasting, and the bus bar connector of use is made of either aluminum or copper.Because the specific conductivity of aluminium is 1/3rd of a copper, so under the identical conductive capability situation, the bus bar connector volume that is formed from aluminium is big, be not easy mounting or dismounting, usually impaired in assembling and dissembling process, reduced work-ing life widely, increased labour intensity simultaneously.With the bus bar connector that copper is done, current-carrying part adopts copper conductor, and copper conductor and copper conducting plates are welded together, and by interim jig conducting plates is crimped on bus and anodic.This mode need all will be installed bus bar connector on each anodic both sides, and the welding quality of copper conductor and conducting plates is difficult to guarantee, the phenomenon that lead and conducting plates disconnect in use often takes place.The bus bar connector of copper conductor also can be owing to the poor radiation of copper conductor, and the rubber of copper conductor is burnt out, and causes fracture of wire in handling process, has a strong impact on the work-ing life of bus bar connector.For these reasons, the safety coefficient of bus bar connector obtains bigger than normal, and an anode must be connected with two bus bar connectors respectively by both sides, with the 186KA electrolyzer is example, 28 on the total anode of this electrolyzer, 14 on every limit, then starting an electrolyzer needs 30 bus bar connectors.
Because two bus bar connectors need be installed on the same anode rod, by wearing the bolt crimping, and the weight of bus bar connector makes difficulty is installed about 35kg, cause easily conducting plates and guide rod surperficial contact poor.The conducting plates unbalance stress often takes place in installation process, and impaired phenomenon.
Generally on bus, have 8 place's specific positions, must make special bus bar connector and could guarantee to be in place, and different grooved specific position differences, the structure of bus bar connector is also different, has directly caused the versatility of bus bar connector poor, can not exchange
Along with the popularization of starting mixture roasting technology, the reliability of bus bar connector, versatility, practicality are more and more paid attention to by people.Therefore, the exploitation calcining aluminium electrolytic tank mixed material starts novel bus bar connector, and requirement can prolong the work-ing life of bus bar connector, is convenient to installing/dismounting, and is applicable to any electrolyzer.
Summary of the invention:
The objective of the invention is to: a kind of physical strength height is provided, compact construction, long service life, versatility is good, can prolong the aluminium cell life-span, saves the bus bar connector of electrobath start cost, to overcome the problems referred to above.

The present invention compared with prior art, it is big to have an area of dissipation, good heat conductivity, long service life, cost is low, versatility is good, advantages such as installation, convenient disassembly.Show that through the test on the 230KA electrolyzer hot face temperature of the soft band of copper is not higher than 150 ℃, bus bar connector is without any distortion and damage, and the life-span of the present invention will be higher than the bus bar connector of present use.The present invention can make anode drop on the mixing bed of material and uniform contact by deadweight, guarantees the pressure basic equalization that compound bears in the groove.By the soft band conduction of copper, guarantee the conducting heavy current (the every about 6500--9000A of anode) of anode and bus; Because the soft band of copper is very soft, can guarantee that anode can have relatively moving of 2--3cm with bus in vertical direction.
Because conducting electricity very well of the soft band of copper, through calculating, every bus bar connector can be born by two blocks of anodic electric currents, the quantity of every cover bus bar connector can be reduced half, has saved cost greatly.Simultaneously, the installation of bus bar connector also can be avoided the several specific positions on the bus, so same set of bus bar connector can be installed on all kinds of electrolyzers, versatility is good.The mode of connection of bus bar connector is to be clamped on guide rod or the bus from one side by temporary fixture, and this mounting means is comparatively simple, and can not damage conducting plates.
