Description
Technical field
The utility model relates to the suction aluminum pipe that uses in the field of aluminum electrolysis, relates in particular to a kind of suction aluminum pipe with the graphite protective casing.
Background technology
In recent years, China's aluminium industrial development is rapid, and electrolytic aluminum output ranks first place, the world, and the aluminium production technology reaches in many aspects or near advanced international standard, especially large-sized prebaked electrolyzer has obtained widespread use, and the smelting level of aluminium has had large increase.Two-maing ladle is visual plant in the Aluminum Electrolysis Production process, and it is mainly bearing from electrolyzer the task with the sucking-off of high temperature aluminum liquid, transhipment.Be all kinds (comprising uncovered two-maing ladle and vacuum ladle) the indispensable important structure of two-maing ladle and inhale aluminum pipe.During work, inhale in the aluminium liquid of aluminum pipe insertion electrolytic aluminum groove, utilize siphon principle, during aluminium water is inhaled into and two-mans ladle.And the temperature of aluminium water is up to 1300 ~ 1400 ℃, and has the ionogen fluorochemical.What this just required to inhale aluminum pipe wants high temperature resistant 1400 ℃ with material, and anti-oxidant under 1400 ℃ of high temperature, and cold and hot fatigue property all will be got well, and can bear 1400 ℃ of high temperature aluminum liquid and electrolytically wash away and corrode.
In order to prolong the work-ing life of inhaling aluminum pipe, a lot of electrolysis of aluminum workers and researcher improve the material of inhaling aluminum pipe, inhale the aluminum pipe inwall but all be based on protection.Be immersed in the high temperature aluminum liquid yet inhale the aluminum pipe bottom, problems such as the oxidation of suction aluminum tube surfaces, high temperature corrosion are still very serious, and inefficacies such as its pitting corrosion that causes, perforation have directly influenced the work-ing life of inhaling aluminum pipe.
Now disclosed patent " graphite suction aluminum casing " (200920319079.9) is made up of graphite sleeve, areole and suction aluminum pipe, has used the characteristics such as high temperature resistant, corrosion-resistant of graphite fibre well.Yet this patent has just installed a device that graphite is made additional in suction aluminum pipe bottom, erosion and the problem of oxidation of inhaling aluminum pipe itself but are not resolved, and simultaneously, the fragility of graphite is bigger, directly below inhaling aluminum pipe, adopt the graphite tube that does not have other propping materials, cause situations such as fracture easily.Have producer to utilize graphite as material recently, made the anti-oxidant suction aluminum pipe of whole graphite, though this graphite is inhaled the oxidation-resistance of aluminum pipe, solidity to corrosion and thermal shock resistance are good, and cost is too high, promotes extremely difficult.Patent " the compound suction aluminum pipe of high strength " (200520118707.9); build at the graphite blank; use lathe precision work again; also just carried out protection to a certain degree to inhaling aluminum pipe inside; but the strength of joint of its graphite blank and external metallization waits further raising; also long term operation is under severe environment such as oxidized, corrosion easily consider to inhale the aluminum pipe outside, and simultaneously, its technological operation difficulty is relatively large.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of suction aluminum pipe of band graphite protective casing of high temperature resistant, corrosion-resistant, long service life that cost performance is high is provided.
Concrete technical scheme of the present utility model is as follows:
A kind of suction aluminum pipe with the graphite protective casing is characterized in that: described graphite protective casing comprises outer tube (1), inner sleeve (2).
As preference:
The internal diameter of described graphite protection outer tube is than inhaling the aluminum pipe outside diameter d
1Big 0 ~ 3mm, the external diameter of graphite protection inner sleeve is than inhaling the aluminum pipe inner diameter d
2Little 0 ~ 3mm.
The wall thickness of described graphite protection outer tube (1), graphite protection inner sleeve (2) is 3 ~ 20mm.
Described graphite protective casing is positioned at the lower end of inhaling aluminum pipe and the height that highly is higher than electrolyzer.
Described graphite protective casing with inhale that aluminum pipe is connected by bolt and the height of bolt is higher than the height of electrolyzer.
The internal diameter of the connection portion of described suction aluminum pipe and graphite protective casing enlarges 3 ~ 20mm, reduced diameter 3 ~ 20mm.
The working method of the suction aluminum pipe of above-mentioned band graphite protective casing is:
Produce the graphite protective casing according to the specification of inhaling aluminum pipe size and aluminium cell, graphite protective casing and suction aluminum pipe are assembled, utilize size to cooperate and make it connect into an integral body.
In the aforesaid method; can adopt bolt to connect; graphite protective sleeve and suction aluminum pipe are carried out reinforcement by connection; when adopting bolt to carry out reinforcement by connection; the height of bolt should be higher than the height of electrolyzer; the number of bolt, size can be according to aluminium cell and the specification practical situation adjustment of inhaling aluminum pipe, and the graphite protective sleeve is that purpose gets final product with inhaling aluminum pipe not soak bolt and to strengthen fixedly.The cooperation intensity that bolt connects according to the graphite protective sleeve determines whether use.
In the aforesaid method, the connection portion internal diameter of former suction aluminum pipe and graphite protective casing can be enlarged 3 ~ 20mm, reduced diameter 3 ~ 20mm cooperates the graphite protective sleeve with installation again, but also fitted bolt connects use simultaneously.
The utility model is inhaled aluminum pipe; all protect with the graphite protective sleeve the common suction aluminum pipe of easy loss is inside and outside; utilize the size cooperation of graphite protective sleeve and suction aluminum pipe to make it connect into an integral body; can play inhaling the unusual effect that aluminum pipe protects, effectively prolong and inhale aluminum pipe work-ing life, simultaneously; because manufacture craft is simple; the cost of material is low, thereby the cost performance of this novel suction aluminum pipe is very high, but batch machining, production.
