Abstract
The invention discloses a novel energy-saving heightening anode group for an aluminium electrolytic bath. The novel energy-saving heightening anode group corresponds to the electrolytic bath. The electrolytic bath is internally provided with a plurality of anode groups; each andoe group comprises an eight-claw component, a carbon block connected at the tail end of the eight-claw component, and an aluminium guiding rod connected with the other end of the eight-claw component; the eight-claw component comprises eight steel claws; and the tail ends of the eight steel claws are connected with the carbon block. The novel energy-saving heightening anode group disclosed by the invention has the advantages that the design is reasonable, the operation is simple and safe, and under the condition without changing the upper-part structure of the existing electrolytic bath, the anode group of the carbon block (H equals to 700mm) is used, so that the use period of the anode can be prolonged to 37.5 days, the carbon consumption is reduced, the labor intensity of workers can also be reduced and large income is brought for production of electrolytic aluminium.
Description
Technical field
The invention belongs to aluminium cell field, specifically, relate to that a kind of aluminium electrolysis bath is energy-conservation increases anode unit.
Background technology
In electrolysis of aluminum, the charcoal block in anode unit constantly consumes along with the carrying out of electrolysis production, and when current efficiency is 92% time, theoretical carbon consumption is 363kg/tAL.But in actual production process, the charcoal block actual consumption amount in anode unit consumes much larger than theoretical carbon, actual carbon consumption reaches 500kg/tAL (containing anode scrap residual content after electrolytic reaction), 100kg at least more than theory consumption.
Reduce ton aluminium carbon consumption to save energy and reduce the cost very important effect to electrolysis of aluminum.
Existing 240KA anode unit that electrolyzer uses, be made up of guide rod (2236mm), explosion block (205*235*50mm), eight pawls (H=480mm), charcoal block (H=580-600mm) four part, its anode life cycle is between 28-30 days.Such consumption, causes higher carbon consumption, also add the labour intensity of workman, bring higher energy consumption, add cost to Aluminum Electrolysis Production.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of aluminium electrolysis bath is energy-conservation increases anode unit, reasonable in design, safety simple to operate, under the prerequisite not changing existing pot superstructure, add anode carbon block height, extend anode change cycle, reduce carbon consumption, can also labor strength be reduced, huge income is brought to Aluminum Electrolysis Production.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of aluminium electrolysis bath is energy-conservation increases anode unit, corresponding with electrolyzer, it is characterized in that: be provided with some anode unit in described electrolyzer; The aluminium guide bar that described anode unit comprises eight claw assemblies, is connected to the charcoal block of eight claw assembly ends, is connected with the eight claw assembly the other ends; Described anode unit is cut down steel pawl height by equivalent and is increased charcoal tile height, and anode unit whole height is remained in design tolerance band, thus reaches and do not change pot superstructure and increase anode carbon block height, extends the object of anode carbon block life cycle.
As a kind of technical scheme of optimization, described anode carbon block height is 700mm.
As a kind of technical scheme of optimization, described eight claw assemblies comprise eight steel pawls that end connects, and the end of steel pawl arranges charcoal block, and steel pawl height is 180mm.
Owing to have employed technique scheme, compared with prior art, the present invention is reasonable in design, safety simple to operate, using the anode unit of charcoal block (H=700mm) when not changing existing electrolyzer shape, anode life cycle to 37.5 day can be extended, reduce carbon consumption, can also labor strength be reduced, huge income is brought to Aluminum Electrolysis Production.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of an embodiment of the present invention.
Embodiment
As shown in Figure 1, a kind of aluminium electrolysis bath is energy-conservation increases anode unit, corresponding with electrolyzer, is provided with some anode unit in described electrolyzer.Described anode unit comprises steel claw assembly 2, is connected to the charcoal block 1 of steel claw assembly 2 end.
In the present embodiment, described eight claw assemblies comprise eight steel pawls that medial end connects, and the end of steel pawl arranges charcoal block.
The height of described charcoal block 1 is increased to 700mm from 600mm, and in described eight claw assemblies, the level height of steel pawl is cut down to 180mm from 280mm, and holding anode group whole height is constant.
Described anode unit is cut down steel pawl height by equivalent and is increased charcoal tile height, and anode unit whole height is remained in design tolerance band, thus reaches and do not change pot superstructure and increase anode carbon block height, extends the object of anode carbon block life cycle.
The present invention is reasonable in design, safety simple to operate, the anode unit of charcoal block is used when not changing existing electrolyzer shape, the height of charcoal block is increased to 700mm, anode life cycle to 37.5 day can be extended, reduce carbon consumption, can also labor strength be reduced, huge income is brought to Aluminum Electrolysis Production.
The present invention can extend anode life cycle by increasing charcoal block effectively to 700mm, falls low-carbon-consumption, can also reduce labor strength, bring huge income to Aluminum Electrolysis Production.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the structural changes made under enlightenment of the present invention, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
