Specific embodiment
Multiple embodiments of the present invention, as clearly stated, the details in many practices will be disclosed with schema below
Will be explained in the following description.It should be appreciated, however, that the details in these practices is not applied to limit the present invention.Also
It is to say, in some embodiments of the present invention, the details in these practices is non-essential.Additionally, for the sake of simplifying schema,
Some known usual structures will illustrate it in the drawings in the way of simply illustrative with component.
Fig. 1 is refer to, which is the online vacuum degassing device schematic diagram of aluminum solutions of an embodiment of the present invention.Herein
In, aluminum solutions are aluminium liquid of the metal aluminium ingot through high temperature melt, and aluminium ingot still has a little impurity, therefore aluminum solutions still need to utilize
The online vacuum degassing device of aluminum solutions of the present invention gives further purification.
As shown in figure 1, the online vacuum degassing device of aluminum solutions includes degasification casing 10, it is arranged inside degasification casing 10
Except gas chamber 20, except 20 bottom of gas chamber is provided with middle baffle plate 30, and middle baffle plate 30 with remove 20 head clearance one of gas chamber
Segment distance, is arranged at except 20 bottom of gas chamber and the circulation entrance 40 and flow outlets 50 positioned at 30 both sides of middle baffle plate, arranges
In except 20 bottom of gas chamber and the drive link 60 positioned at 30 both sides of middle baffle plate, 60 one end of drive link is provided with rotor 70, and turns
Sub 70 surfaces are connected with the multiple through holes 710 inside connection rotor 70, and are arranged at degasification casing 10 and connect except gas chamber 20
Vacuum pump 100.Thus one, the online vacuum degassing device of aluminum solutions of the present invention when using 100 degasification of vacuum pump, degasification
, under vacuum environment, the atmospheric pressure being subject to is stronger for aluminum solutions in chamber 20, therefore the impurity in aluminum solutions overflows speed
Also can be more preferable with efficiency.
Please continue to refer to Fig. 1, in an embodiment of the present invention, drive link 60 can utilize sealing ring with except gas chamber 20
(not illustrating) seals, it is ensured that drive link 60 prevents the leakage of aluminum solutions in high-speed motion.Additionally, 10 side of degasification casing is arranged
Have around hermatic door 80, and hermatic door 80 and be provided with sealing ring 90.Consequently, it is possible in aluminum solutions degasification, shut hermatic door 80, make
A closing space must be in except gas chamber 20, sealing ring 90 is then ensure that well except gas chamber 20 and the sealing of hermatic door 80
Property, easily and effectively work；And after the completion of working as aluminum solutions degasification, hermatic door 80 is opened, impurity that also can be in easy cleaning aluminum solutions,
Realize the multiple effectively utilizes of depassing unit of the present invention.
In addition, in an embodiment of the present invention, be connected with inside rotor 70 and (do not illustrate) except gas carrier, it is at full speed in rotor 70
While rotation, except gas carrier is thrown away from through hole 710 along inside rotor 70, form tiny bubble and be passed through aluminum solutions bottom,
The rotor 70 of rotation tiny bubble is dispersed as except gas carrier, under the pressure of aluminum solutions, bubble floating, by absorption principle
As long as foreign gas in aluminum solutions (hydrogen) and non-metallic particle being taken out of and floating to aluminum solutions surface, the mesh of degasification slagging-off is reached
's.Additionally, the present invention is arranged at rotor 70 and drive link 60 except 20 bottom of gas chamber, it is to avoid in prior art, by rotor
70 stretch into aluminum solutions bottom from aluminum solutions surface, due to rotation, the scum silica frost on aluminum solutions surface are involved in aluminum solutions again, are formed
The problem of secondary pollution, is unfavorable for the purification of aluminum solutions.
In sum, operation principle of the invention be by one it is closed with vacuum pump 100 except gas chamber 20, degasification
20 bottom of chamber is provided with middle baffle plate 30, circulation entrance 40 and flow outlets 50, and pending aluminum solutions are constantly imported stream
Mouth 40 is passed through, when aluminum solutions cover circulation entrance 40 and flow outlets 50 except gas chamber 20, except gas chamber 20 forms one
The space of closing.When degasification starts, vacuum pump 100 is opened 20 inside sucked vacuum of gas chamber is removed, aluminum solutions are by atmospheric pressure pressure
Enter except gas chamber 20, when reaching a certain height except the aluminum solutions of gas chamber 20, vacuum pump 100 quits work, liquid level and degasification
Portion gap is left at the top of chamber 20, that is, there is partial vacuum, the gas being more beneficial in aluminum solutions overflows rapidly, while transmission
60 rotor driven 70 of bar rapidly rotates, and except gas carrier is thrown away from through hole 710 along inside rotor 70, forms tiny bubble and is passed through
Aluminum solutions bottom, the rotor 70 of rotation tiny bubble is dispersed as except gas carrier, under the pressure of aluminum solutions, bubble floating,
As long as foreign gas in aluminum solutions (hydrogen) and non-metallic particle being taken out of by absorption principle and floating to aluminum solutions surface, reach
The purpose of degasification slagging-off.Because being sealing except gas chamber 20 exports 50 and removes inside gas chamber 20 from connection entrance 40 to connection
, circulation entrance 40 constantly imports aluminum solutions, now opens flow outlets 50, and according to siphon principle, aluminium liquid can constantly from removing
Flow through in gas chamber 20, specified containers are flowed to from flow outlets 50, complete degasification and slagging-off work.
Embodiments of the present invention are the foregoing is only, the present invention is not limited to.For people in the art
For member, the present invention can have various modifications and variations.It is all the present invention principle in made any modification, equivalent,
Improve etc., all should be included within scope of the presently claimed invention.
