Description
Technical field
This application involves generating metal magnesium by electrolyzing magnesium chloride fields more particularly to High aititude to shift the vehicle-mounted lift of molten metal magnesium
Bag apparatus.
Background technique
With the magnesium chloride development of resources of the amount of containing high in the exploitation of high altitude localities salt lake resources, especially salt lake, make
The electrolysis of magnesium chloride production magnesium metal and chlorine Processes and apparatus highlands be able to apply and development.The electrolysis of magnesium chloride
Cheng Zhonghui generates magnesium metal, is initially to exist in the form of molten metal magnesium, and also to carry out repeatedly in the process of production
Transfer is further finished in different process equipments with realizing, final to obtain the metal magnesium ingot for meeting the requirements quality
Or magnesium alloy.Molten metal magnesium from electrolytic cell goes out magnesium and transfer in each process equipment then and becomes to realize whole in the process
Body magnesium ingot and the necessary process of magnesium alloy production.
The transfer process of earliest initial stage conventional melt magnesium metal mainly manually realizes, however artificial realizes melting gold
The transfer of category magnesium be there is a problem that many.It is primarily due to the high temperature that molten metal magnesium there are about 700 DEG C, manually goes out magnesium so that depending merely on
And there are great security risks for the process shifted；Secondly manually go out magnesium in the electrolysis of magnesium chloride production of high yield to be obviously difficult to
Realize matched magnesium and transport capacity out.Why such method is traditional magnesium eletrolysis the reason of can be applied at that time
Yield is universal relatively low and without corresponding special equipment.Magnesium out artificial simultaneously, which lacks molten metal magnesium in the process of transfer, to be protected
Warm measure makes the time needed for obtaining magnesium and transfer process have very high limitation, primarily to preventing molten metal magnesium from existing
Solidification in transfer process.
Later period as the production capacity of the electrolysis of magnesium chloride constantly expand and it is artificial go out magnesium existing for problems answering of to two-man ladle
With being developed.Although tradition is two-mand ladle for going out the transfer ability of magnesium and molten metal magnesium to have compared with manual method and significantly be mentioned
Height, while solving artificial magnesium out and the safety problem of transfer, but there is many deficiencies.
Liner must be preheated before operation by two-maing ladle first, and tradition two-man ladle before magnesium out liner preheating mainly according to
It leans against using melt transfer pipe that the heat in closing down magnesium electrolysis bath above molten metal magnesium is empty while vacuumize operation in liner
Aspiration enters liner and is preheated, and the process makes to show that magnesium operation, the time that place occupies and overhead traveling crane occupies are longer, accounts for entire molten
The ratio for melting the magnesium metal transfer tasks time is great, seriously limits operating efficiency, it is difficult to adapt to the needs of high production capacity.Although compared with people
The efficiency of work improves, but needs further to be solved.
Secondly tradition, which is two-mand ladle, mainly relies on the negative pressure of vacuum formed in liner of two-maing ladle and melt transfer pipe by closing down magnesium electrolysis bath
Middle molten metal magnesium is pumped into liner and carries out out magnesium operation.And the height of negative pressure of vacuum not only decides in liner in the process
The size of the height difference of magnesium also decides the size of suction speed of the molten metal magnesium in pipe out, can make if suction speed is excessively slow
The blocking that solidification causes tube body occurs at the molten metal magnesium in melt transfer pipe.Tradition, which is two-mand ladle, herein to rely in reduction
Gallbladder volume and matched vacuum system ability is improved to carry out the promotion of negative pressure of vacuum to it, and vacuum system ability mentions
The limitation for suffering from investment, local atmospheric pressure and technique itself is risen, this allows for traditional volume two-mand ladle by very big
Limitation.But with electrolytic chlorination magnesium production capacity it is continuous expansion and tradition two-man ladle liner volume limitation problem so that tradition is two-mand ladle
It is difficult to meet industry production capacity demand now.This problem is more prominent in the small high altitude localities of atmospheric pressure.
In addition, tradition two-mans ladle and two-mans ladle inside liner that there are a large amount of sublimates when carrying out out magnesium operation, and these distil
Object can be brought into vacuum pipe while liner vacuumizes and be attached on inner wall of the pipe, and vacuum pipe latus rectum is caused to reduce
Pipe end negative pressure reduces, and even will cause the blocking of pipeline when serious.These are attached to the sublimate of inner wall of the pipe not simultaneously
Just it inspects periodically and is difficult to effectively be cleared up.

Working principle of the present invention is as follows: before magnesium operation out by electric heating wire be powered to the liner two-mand ladle into
Row preheating after preheating reaches assigned temperature, is reliably fixed on lifting to the two-man ladle transportation vehicle that will two-man ladle and is transported at electrolytic cell
Carry out out magnesium operation.It is existing when magnesium operation out to close plug valve spool, liner inside vacuumize by vacuum tube straight
Reach specified negative pressure value to liner internal negative pressure, melt transfer pipe is inserted into the molten metal magnesium of electrolytic cell, while controlling plug
Valve control device opens plug valve spool, and the negative pressure being previously formed in liner at this time can quickly extract magnesium liquid, in this process
Middle vacuum tube should continue to provide negative pressure, to guarantee smoothly completing for whole process.When the liquidometer at top of two-maing ladle shows that liquid level reaches
When to specified altitude assignment, plug valve is closed, while removing is external in the vacuum line for vacuum tube of two-maing ladle.To two-man ladle at this time, it is next to be transported to
The operation that molten metal magnesium of two-maing ladle is discharged is carried out at the equipment of process, only need to open plug valve spool of two-maing ladle can be realized the operation,
It at this time can also be by adjusting the discharge rate of interior melt of two-maing ladle to the control of plug valve spool.When two-maing ladle, interior melt is completely exhausted out
Afterwards, can directly carry out next round goes out magnesium operation.
Transfer tasks are carried out using the molten metal magnesium that above-mentioned two-maing ladle carries out electrolysis of magnesium chloride generation, warm is
Be lifted into two-man ladle transport vehicle or other equipment before preheated, do not need to occupy the available of two-man ladle transportation vehicle or other equipment
Time, the time of this process saving account for about the 70%-80% of traditional magnesium operation of two-maing ladle out.The function that cut-offs of plug valve spool can be realized
The quick extraction of molten metal magnesium greatly reduced melt so that the plugging rate of melt transfer pipe reduces 70-80% more in the past
The maintenance cost of transfer pipe.This advantage then becomes apparent in the highlands of low atmospheric pressure.Table 1 is provided by the invention two-mans ladle
Compared with the main indicator that tradition is two-mand ladle.
