Description
Technical field
The present invention relates to off gas system, and in particular to a kind of off gas system for aluminium casting raw material being aluminium liquid.
Background technology
Aluminium casting production in, aluminium ingot in smelting furnace high temperature melt into melting aluminium liquid, due to high-temperature gas be present in smelting furnace
With other various impurity, need to pre-process aluminium liquid before aluminium liquid is imported in die casting, after molten aluminum liquid is up to standard
Die Casting can be carried out.Aluminium liquid is pre-processed, that is, needs to carry out degasification and slagging-off to molten aluminum liquid.In degassing procedure, if aluminium
Contain hydrogen or other impurities gas in liquid, the physical property, mechanical property and performance of product can be had a strong impact on, be mixed with
The aluminium casting of impurity can form stomata, and it is loose to cause aluminium casting.The particularly presence of hydrogen, very big, casting is endangered aluminium casting
Hydrogen embrittlement occurs in too high hydrogen content during part, it is therefore necessary to carries out degasification to aluminium liquid.
The content of the invention
To there is the defects of technology on overcoming, the purpose of the present invention, which is directed to one kind, to carry out pretreatment early stage to aluminium liquid
Aluminium liquid off gas system.
To achieve the above object, the present invention is using following technical scheme：
A kind of aluminium liquid off gas system, it is characterised in that：Including the first gas cylinder, the second gas cylinder, gas mixing tank, degasification tank
Body；First gas cylinder is connected to the air inlet of gas mixing tank by tracheae, and air valve is housed on tracheae；Second gas cylinder leads to
The air inlet that tracheae is connected to gas mixing tank is crossed, air valve is housed on tracheae；The bottom of the gas mixing tank is provided with ventilation mouth,
Both sides are welded with lateral frame；The lateral frame is connected with main support by universal coupling with spider；The gas mixing tank
Certain distance be present with ground；The gas outlet of the gas mixing tank is connected to by tracheae in the air flue of degasification casing, tracheae
It is upper that air pump is housed；The air flue of convex shape is provided with the inside of the degasification casing；Air brick is provided with above the air flue；It is described
The center of air brick is provided with the primary air inlet being connected with air flue.
The explanation of such scheme and further scheme are as follows：
Preferably, covered with one layer of high temperature resistant permeable membrane on the air brick.
Preferably, first gas cylinder is built with nitrogen.
Preferably, second gas cylinder is built with argon gas.
Because above-mentioned technical proposal is used, the present invention has following advantages：
A kind of aluminium liquid off gas system provided by the invention, fully the hydrogen in aluminium liquid and other foreign gases can be arranged
Go out, complete degasification pretreatment is carried out to aluminium liquid under the atmosphere of whole protective gas, do basis for subsequent production, further carry
High yield quality.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In the figures above：1st, the first gas cylinder；2nd, the second gas cylinder；3rd, gas mixing tank；4th, degasification casing；5th, air valve；6th, it is horizontal
Support；7th, main support；8th, air flue；9th, air pump；10th, air brick；11st, primary air inlet；12nd, high temperature resistant permeable membrane.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment：It is shown in Figure 1：
A kind of aluminium liquid off gas system, including the first gas cylinder 1, the second gas cylinder 2, gas mixing tank 3, degasification casing 4；First gas
Bottle 1 is connected to the air inlet of gas mixing tank 3 by tracheae, and air valve 5 is housed on tracheae；Second gas cylinder 2 is connected to by tracheae
The air inlet of gas mixing tank 3, air valve 5 is housed on tracheae；The bottom of gas mixing tank 3 is provided with ventilation mouth, and both sides are welded with horizontal stroke
Support 6；Lateral frame 6 is connected with main support 7 by universal coupling with spider；A spacing be present with ground in gas mixing tank 3
From；The gas outlet of gas mixing tank 3 is connected in the air flue 8 of degasification casing 4 by tracheae, and air pump 9 is housed on tracheae；Degasification tank
The inner side of body 4 is provided with the air flue 8 of convex shape；The top of air flue 8 is provided with air brick 10；The center of air brick 10 be provided with
The primary air inlet 11 that air flue 8 connects；Covered with one layer of high temperature resistant permeable membrane 12 on air brick 10；First gas cylinder 1 is built with nitrogen；
Second gas cylinder 2 is built with argon gas.
The air valve 5 that the second gas cylinder 2 is connected with gas mixing tank 3 on tracheae is opened, the argon gas in the second gas cylinder 2 is passed into
In gas mixing tank 3, first the air in gas mixing tank 3 is discharged, is allowed to be full of argon gas in it, then opens the first gas cylinder 1
The air valve 5 being connected with gas mixing tank 3 on tracheae, the nitrogen in the first gas cylinder 1 is passed into gas mixing tank 3.Due to gas
