Description
Technical field
The utility model relates to gas-freeing system, is specifically related to a kind of for the gas-freeing system to aluminium casting raw material and aluminium liquid.
Background technology
During aluminium casting is produced, aluminium ingot high-temperature molten in smelting furnace changes into the aluminium liquid of melting, owing to there are high-temperature gas and other various impurity in smelting furnace, need to carry out pre-treatment to aluminium liquid being imported before in die casting by aluminium liquid, molten aluminum liquid is up to standard just can carry out Die Casting afterwards.To the pre-treatment of aluminium liquid, namely need to carry out degasification and slagging-off to molten aluminum liquid.In degassing procedure, if containing hydrogen or other foreign gas in aluminium liquid, can have a strong impact on the physicals of product, mechanical property and use properties, the aluminium casting being mixed with impurity can form pore, causes aluminium casting and loosens.The particularly existence of hydrogen, very large to aluminium casting harm, hydrogen content too high in foundry goods process there will be hydrogen embrittlement, therefore must carry out degasification to aluminium liquid.
Utility model content
For there being the defect of technology on overcoming, the purpose of this utility model is intended to propose one can carry out pretreated aluminium liquid gas-freeing system in early stage to aluminium liquid.
For achieving the above object, the utility model adopts following technical scheme:
A kind of aluminium liquid gas-freeing system, is characterized in that: comprise the first gas cylinder, the second gas cylinder, gas and vapor permeation tank, degasification casing; Described first gas cylinder is connected to the inlet mouth of gas and vapor permeation tank by tracheae, tracheae is equipped with air valve; Described second gas cylinder is connected to the inlet mouth of gas and vapor permeation tank by tracheae, tracheae is equipped with air valve; The bottom of described gas and vapor permeation tank has scavenge port, and both sides are welded with lateral frame; Described lateral frame is connected by universal coupling with spider with main support; There is certain distance in described gas and vapor permeation tank and ground; The air outlet of described gas and vapor permeation tank is connected in the air flue of degasification casing by tracheae, and tracheae is equipped with air pump; The inner side of described degasification casing has the air flue of convex shape; The top of described air flue is provided with gas permeable brick; The central position of described gas permeable brick has the primary air inlet be connected with air flue.
Explanation and the further scheme of such scheme are as follows:
Preferably, described gas permeable brick is coated with the high temperature resistant permeable membrane of one deck.
Preferably, described first gas cylinder is built with nitrogen.
Preferably, described second gas cylinder is built with argon gas.
Because technique scheme is used, the utility model has following advantages:
A kind of aluminium liquid gas-freeing system that the utility model provides; fully the hydrogen in aluminium liquid and other foreign gas can be discharged; under the atmosphere of whole shielding gas, degasification pre-treatment is completely carried out to aluminium liquid, for subsequent production does basis, improve the quality of products further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In above accompanying drawing: 1, the first gas cylinder; 2, the second gas cylinder; 3, gas and vapor permeation tank; 4, degasification casing; 5, air valve; 6, lateral frame; 7, main support; 8, air flue; 9, air pump; 10, gas permeable brick; 11, primary air inlet; 12, high temperature resistant permeable membrane.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 1:
A kind of aluminium liquid gas-freeing system, comprises the first gas cylinder 1, second gas cylinder 2, gas and vapor permeation tank 3, degasification casing 4; First gas cylinder 1 is connected to the inlet mouth of gas and vapor permeation tank 3 by tracheae, tracheae is equipped with air valve 5; Second gas cylinder 2 is connected to the inlet mouth of gas and vapor permeation tank 3 by tracheae, tracheae is equipped with air valve 5; The bottom of gas and vapor permeation tank 3 has scavenge port, and both sides are welded with lateral frame 6; Lateral frame 6 is connected by universal coupling with spider with main support 7; There is certain distance in gas and vapor permeation tank 3 and ground; The air outlet of gas and vapor permeation tank 3 is connected in the air flue 8 of degasification casing 4 by tracheae, tracheae is equipped with air pump 9; The inner side of degasification casing 4 has the air flue 8 of convex shape; The top of air flue 8 is provided with gas permeable brick 10; The central position of gas permeable brick 10 has the primary air inlet 11 be connected with air flue 8; Gas permeable brick 10 is coated with the high temperature resistant permeable membrane 12 of one deck; First gas cylinder 1 is built with nitrogen; Second gas cylinder 2 is built with argon gas.
Open the second gas cylinder 2 and be connected air valve 5 on tracheae with gas and vapor permeation tank 3, argon gas in second gas cylinder 2 is passed in gas and vapor permeation tank 3, first the air in gas and vapor permeation tank 3 is discharged, make it to be full of argon gas in it, then open the first gas cylinder 1 and be connected air valve 5 on tracheae with gas and vapor permeation tank 3, the nitrogen in the first gas cylinder 1 is passed in gas and vapor permeation tank 3.Because gas and vapor permeation tank 3 is maked somebody a mere figurehead, and lateral frame 6 is connected by universal coupling with spider with main support 7, and therefore gas and vapor permeation tank 3 can rock and the nitrogen in tank and argon gas are fully mixed with this in front and back.Open gas and vapor permeation tank 3 and be connected air pump 9 on tracheae with degasification casing 4, mixed gas is passed in the air flue 8 of degasification casing 4, after passing into for some time, molten aluminum liquid is poured in degasification casing 4.Mixed gas in air flue 8 enters in molten aluminum liquid by gas permeable brick 10 and primary air inlet 11, and due to gas permeable brick 10 having the high temperature resistant permeable membrane 12 of one deck, therefore gas can be passed in aluminium liquid smoothly, and aluminium liquid cannot penetrate in gas permeable brick 10.Mixed gas is passed in aluminium liquid endlessly, removes, reach the object of degasification by aluminium liquid containing air.
