Abstract

The utility model relates to a crossbeam anode claw with steel shell and aluminium core for aluminium cell, which comprises an aluminum core, an aluminum core boss, a steel shell, a round steel, a mesh plate and a steel claw. After the welding of the steel shell, the aluminum core and the steel shell can be cemented in the mode of aliting cement casting in order to assure the structural strength and the sufficient aliting cement between the aluminum core and the crossbeam steel shell. The conductive performance of the crossbeam anode claw with steel shell and aluminium core is superior to various exiting anode claws, the practical testing pressure drop value can be reduced under 20 mv, which is reduced by 50% more than the pressure drop values of various exiting anode claws, and the utility model has the effect of saving electricity and reducing consumption.

Description

A kind of aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw

The utility model design relates to a kind of Aluminum Electrolysis Production equipment, specifically is a kind of aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw.

Aluminum electrolyzing cell used anode claw is the important consumable part of Aluminum Electrolysis Production.For a long time, Aluminum Electrolysis Production is all used cast steel type anode claw both at home and abroad, because the anode claw working current reaches 7500A, therefore, the anode claw conductivity is very big to the influence of Aluminum Electrolysis Production power consumption index.Now both at home and abroad the cast steel type anode claw work pressure drop of widespread usage is 40～50mV, and one day about 9kWh of power consumption of every anode claw produces the factory of 100,000 tons of electrolytic aluminums, about 32,400,000 kWh of annual anode claw consumes power per year.Be to reduce the anode claw power consumption, manufacturer has all carried out big quantity research to the material of cast steel type anode claw, structure, mode of connection etc. both at home and abroad.The cast steel type anode claw that generally uses is difficult to realize more excellent conductivity now, existing monoblock type box hat aluminium core anode claw, there is the structural strength deficiency, defective such as yielding, facts have proved that it can not reach reduces resistance and satisfies the requirement that actual production is used.

The purpose of the utility model design: a kind of new aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw is provided, solve structural strength deficiency, problem such as yielding, guarantee reaches than the existing more excellent conductivity of various anode claws, thereby reach the purpose of Aluminum Electrolysis Production economize on electricity consumption reduction, ensure that simultaneously its structural strength satisfies the requirement that actual production is used.

The implementation of the utility model purpose is: the aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw that is provided is by the aluminium core, aluminum core boss, Steel Sheel, round steel, gusset, compositions such as steel pawl, Steel Sheel is the hollow rectangular structure that is welded by steel plate, reserve aluminum core boss above the Steel Sheel and stretch out the hole, the Steel Sheel inner bottom part is welded with gusset, the round steel of some reinforcement usefulness of gusset top welding, reserving both sides that aluminum core boss stretches out the hole above the Steel Sheel is welded with two and strengthens gussets, strengthen being welded with between the gusset round steel of strengthening usefulness for two, the aluminium core, aluminum core boss and Steel Sheel adopt aluminising bonding casting technique to be cast as box hat aluminium core crossbeam, the aluminium core is filled in the Steel Sheel, aluminum core boss will be strengthened the round steel and the gusset parcel of usefulness above the Steel Sheel, the bottom surface that more some steel pawls is welded on Steel Sheel after box hat aluminium core crossbeam cast member is cast constitutes aluminum electrolyzing cell used conductive anode pawl.

This aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw, realize aluminium core and crossbeam Steel Sheel bonding and ensure that it manufacture method that possesses excellent conductivity is an aluminising bonding casting technique, aluminium core and Steel Sheel bonding back tensile strength can be near the intensity with trade mark cast aluminium, and ensure that its conductivity reaches design requirements.The aluminium core of conductivity excellence extends to steel pawl top in the box hat aluminium core crossbeam, can reduce resistance and reduce the pressure drop of anode claw than former cast steel type crossbeam, and power savings is remarkable, has broad prospect for its application.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the synoptic diagram of the aluminum electrolyzing cell used box hat aluminium of the utility model core crossbeam anode claw;

Fig. 2 is the A-A sectional view of Fig. 1.

As Fig. 1, shown in Figure 2, aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw is by aluminium core (6), aluminum core boss (1), Steel Sheel (5), round steel (2,4), gusset (3,7), steel pawl compositions such as (8), Steel Sheel (5) be by steel plate be welded hollow rectangular structure, reserve the hole of stretching out of aluminum core boss (1) above the Steel Sheel (5), Steel Sheel (5) inner bottom part is welded with gusset (7), the round steel (4) of some reinforcement usefulness of gusset (7) top welding, be used to increase the intensity of Steel Sheel (5), strengthen gusset (3) for two and be welded on the both sides that Steel Sheel (5) top reservation aluminum core boss (1) stretches out the hole, the round steel (2) of strengthening usefulness is welded on two and strengthens between the gusset (3), aluminium core (6), aluminum core boss (1) adopts aluminising bonding casting technique to be cast as box hat aluminium core crossbeam with Steel Sheel (5), aluminium core (6) is filled in the Steel Sheel (5), aluminum core boss (1) is with round steel (2) and gusset (3) parcel, round steel (2) and gusset (3) play the effect of strengthening aluminum core boss (1) intensity, constitute aluminum electrolyzing cell used conductive anode pawl with some steel pawls (8) welding again after box hat aluminium core crossbeam cast member is cast.

Test result shows, the conductivity of this aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw is better than the monoblock type box hat aluminium core anode claw of original castmethod manufacturing and the cast steel type anode claw that generally uses greatly, practical test voltage drop value is below 20mV, reduce more than 50% than original various anode claw voltage drop values, power savings is obvious.Simultaneously, owing to having cancelled the blast weld tabs that needs when original cast steel type anode claw and conductive aluminum bar are connected and installed, can also significantly reduce installation cost, the minimizing anode claw comes off and maintenance cost.This aluminum electrolyzing cell used box hat aluminium core crossbeam anode claw manufacturing process is simple to operate, and product performance are stable, and production cost is no more than former cast steel type anode claw, has possessed the sufficient condition that comprehensively substitutes cast steel type anode claw, and application prospect is very wide.
