Anode conducting clamping fixture

Abstract

The invention discloses an anode conducting clamping fixture, which is used for connecting an aluminum guide rod and an anode carbon block of an aluminum electrolysis bath anode conducting device. The anode conducting clamping fixture is characterized by consisting of conducting side clamping plates on two sides and a clamping adjustment mechanism, wherein the upper end of the anode conducting clamping fixture is connected with the lower end of the aluminum guide rod through a wire; and the lower end of the anode conducting clamping fixture is conductively connected with a lug boss on the upper part of the anode carbon block in a clamping way. By using the anode conducting clamping fixture, because the assembling mode for the conventional anode steel talon, ferro-phosphorous ring and anode carbon block is cancelled, and the current of the aluminum guide rod is transferred to the anode carbon block by using a copper carbon combination transitional connection mode, the voltage drop of the anode conducting device and the resistance power consumption of the aluminum electrolysis bath conducting structure can be reduced, and meanwhile the assembly process cost of the anode carbon block and the press removing process cost of the residual anode are reduced.

Description

technical field [0001] The anode conductive clamping fixture is mainly used in the production and assembly of the aluminum guide rod and the anode carbon block of the anode conductive device of the aluminum electrolytic cell. Background technique [0002] The current general-purpose aluminum electrolytic cell anode conductive device is mainly composed of aluminum guide rods, explosive welding sheets, anode steel claws, anode carbon blocks and phosphorus iron rings. The anode steel claws and anode carbon blocks are formed by casting phosphorus iron rings. Connection of anode carbon blocks to steel claw heads. The anode conductive device of the aluminum electrolytic cell is not only a conductive part, but also a load-bearing part, so firstly, it must have a low resistance, secondly, it must have a certain tensile strength, and thirdly, it must have a certain high temperature resistance.

AI Technical Summary

Problems solved by technology

[0003] The current general-purpose aluminum electrolytic cell anode conduction device mainly has the following disadvantages: first, the iron-carbon contact resistance of the iron-carbon ring used for connection between the anode steel claw and the anode carbon block is relatively large, and the average voltage drop is about 130mv; The phosphorus iron ring between the carbons adopts the hot casting process of molten cast iron and the cost is relatively high; the third is that the separation of the anode butt and the phosphorus iron ring, the separation of the phosphorus iron ring and the anode steel claw head adopts a mechanical pressing or hammering process, and the cost is relatively high. The fourth is that the current density distribution of the anode carbon block is uneven due to the deformation of the anode steel claw and the partial pouring of the phosphorus iron ring.
