Description
Technical field
The present invention relates to a kind of anode steel claw attachment, especially a kind of anode steel claw strainer.
Background technique
Modern Aluminium Industry generallys use prebaked anode production electrolytic aluminium.2~4 are equipped in anode carbon block upper surface
Diameter is 160~180mm, and depth is the circular groove of 80~110mm, is commonly called as charcoal bowl, and in anode assembling, charcoal bowl is used to install anode claw
Head, and cast in anode joint in charcoal bowl with the phosphorus pig iron, anode joint and aluminium conducting rod are exploded by aluminum steel and weld connection, then
It connect aluminium conducting rod closely with anode carbon block, forms anode carbon block group.During Aluminum Electrolysis Production, anode carbon block can be because of it
It decomposites the oxygen come with alumina eltrolysis constantly to react release carbon dioxide at high temperature and constantly consume, therefore anode carbon block
It need to periodically connect, remaining carbon block is commonly called as anode anode scrap after connection.The production technology has the following disadvantages at present, and 1) connection
New anode carbon block is in normal-temperature, and to be put into electrolytic cell after preheating in about 24 hours could be conductive, therefore jointed anode charcoal
Block can be such that heat loss increases, and very big to the stable working impact of electrolytic cell when change poles；2) connection of anode can be raw to aluminium electroloysis
Producing to be formed periodically influences, and destroys the energy and material balance of electrolytic cell, influences current efficiency, increases power consumption rate；3) in order to
Anode joint is separated with anode anode scrap, needs to break into pieces in the charcoal bowl at phosphorus pig iron casting, keeps anode anode scrap de- from anode joint
It falls to realize separation, the process is not only time-consuming, but also labor intensity of workers is big, low efficiency；4) the anode anode scrap under connecting generates
Amount is generally the 10%~15% of aluminium ingot yield, is 26,000,000~27,000,000 tons/year of calculating by China's aluminium ingot yield, generates every year
Anode anode scrap is 2,600,000~3,900,000 tons/year, is calculated according to 2700 yuan/ton of anode carbon block, and annual China can waste value up to hundred
Hundred million yuan of anode carbon block；4) it because anode carbon block itself has 15%~18% porosity, therefore has been adsorbed in anode anode scrap a large amount of
Electrolyte, the main component of electrolyte are fluoride salts, and the anode anode scrap environmental pollution containing a large amount of fluoride salts is extremely serious；5)
When that will cast in anode joint in charcoal bowl, in order to reduce the waste of anode anode scrap, it is necessary to it is as far as possible that anode anode scrap burning is thin, in sun
Pole carbon block end of lifetime, the top surface of anode carbon block is very close to electrolyte level face, by magnetic field and airflow influence, bath surface
Constantly there is strong wave to generate, in the actual production process, anode joint is often corroded by electrolyte, the ferro element of anode joint
It dissolves in electrolyte, enters aluminium ingot immediately, influence quality of finished；At 3 years or so, this also made to give birth to the general service life of anode joint
It produces cost to increase accordingly, and in anode carbon block end of lifetime, excessively thin anode anode scrap thickness necessarily brings charcoal extremely conductive uneven,
And then leading to electrolytic cell fluctuation of operating conditions, power consumption increases.To improve the usage mode of existing anode carbon block, the life of non-residual electrode is realized
Produce, to reduce cost, not only improvement anode carbon block, it is necessary to be the relevant whole system of anode carbon block is improved, and
If existing aluminium cell will stop slot transformation, fire resistant heat preserving structure, anode stub in pot superstructure and bottom pot shell,
Cathode carbon pieces etc. are scrapped completely, lose huge, and the expense also ten that the structures such as bus, portal frame above electrolytic cell remanufacture
Divide high.Numerous studies have also been made before in applicant, and have applied for a series of patent, and the connection of anode carbon block and steel pawl is adopted
With mechanical connection, for realizing the continuous use of anode carbon block.But still there are anode carbon blocks and steel claw structure to change big, use
Inconvenient disadvantage.
Summary of the invention
The object of the present invention is to provide a kind of anode steel claw strainers.The present invention has structure simple, improvement cost
It is low, the features such as realizing the function that steel pawl is mechanically connect with anode carbon block, reach non-residual electrode production.
Technical solution of the present invention: anode steel claw strainer, including the fastener connecting with steel pawl, fastener is equipped with insertion
The fastening block of charcoal bowl, fastener connect the bracket for moving fastening block.
Anode steel claw strainer above-mentioned, the fastener and fastening block are placed in the mounting groove in steel pawl.
The interconnecting piece of anode steel claw strainer above-mentioned, the bracket connection bull stick, bracket and bull stick, which is respectively equipped with, to be nibbled
The saw tooth belt of conjunction and sawtooth end, the bracket connect sliding bar, and sliding bar passes through bracket connection card.
The fastener is rotation axis, and connecting bracket upper end below rotation axis, pedestal lower end is equipped with fastening block.
Anode steel claw strainer above-mentioned, the bracket and fastening block are placed in the mounting groove in steel pawl.
Compared with prior art, strainer of the present invention can be realized steel pawl and mechanically connect with anode carbon block, in use,
The connection of anode carbon block and steel pawl is changed to aluminum water casting, since the fusing point of aluminium is at 660 degree, and temperature is up to 950 in electrolytic cell
Degree, with the progress of aluminum electrolysis process, anode carbon block is constantly consumed, by the heat transfer of anode carbon block, so that charcoal block body charcoal
Aluminium in bowl melts, and after the strainer of auxiliary is tightened, can integrally take out steel pawl and strainer, anode carbon at this time
Block is fixed by the condensed layer load-bearing of the mulch and electrolyte of carbon block surrounding.Pass through the fixation plush copper of new carbon block body bottom portion
New and old charcoal block body is connected with the charcoal bowl of old charcoal block body, steel pawl is fixed on the charcoal bowl of new charcoal block body by aluminum water casting
Interior, the aluminum water in old charcoal block body charcoal bowl improves the conductivity of anode carbon block as conductive material at this time.In old charcoal block body charcoal
In bowl in aluminium melting process, it is fixed by the fixation annular groove cooperation of the strainer and charcoal bowl of steel pawl, at this time charcoal block body
Most of scaling loss, and there is part to immerse load-bearing in electrolyte, therefore the load-bearing requirements of strainer reduce.
The present invention can be realized the continuous use of pre-baked anode carbon blocks non-residual electrode production, use the structure of steel pawl and existing
It compares, only increases strainer, without structures such as carbon block connection auxiliary hooks；Because of the mulch and electrolyte by carbon block surrounding
Condensed layer load-bearing, achieved that without crust breaking and connect pole work, the workload of potroom is greatly decreased, and worker is not when working
It need to face 950 DEG C of hot operation.The improvement cost of existing electrolytic aluminium plant can be reduced, while the operation of potroom can be reduced
Cost improves working environment.The anode carbon block that a kind of pre-calcining electrolytic cell non-residual electrode applied before present invention applicant generates
Structure, application No. is 201610104972.4, connect plush copper, a kind of another prebaked anode of patent using the exposed T shape of surrounding
Aluminium electroloysis continuous producing method and structure are connected application No. is 201610526791.0 using built-in L-type, steel pawl and anode
Carbon block is all made of mechanical connection, and needs auxiliary hanging part.The application further simplifies the structure of steel pawl, reduces transformation
Cost, it is more convenient to use.
