Embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
As shown in Figure 1, a kind of gas contact-type is from foamed assembly, comprising:
Perfusion tube 1 is provided with fluid passage 11 on the perfusion tube 1；
Appendix 2, the appendix 2 are set to 1 inside of perfusion tube and are coaxially disposed with the perfusion tube 1, the gas transmission
Gas passage 21 is provided on pipe 2；
The fluid passage 11 and gas passage 21 are gentle by the fluid passage 11 in the vertical direction in setting up and down
The outside conveying aluminum liquid in body channel 21 and gas, molten aluminum and gas contact with each other during ejection.
It should be noted that 1 fluid passage 11 of perfusion tube injection molten aluminum is formed when there is liquid to flow through the perfusion tube
Fluid curtain 114 makes the circumferential cloth in 11 lower section of fluid passage since the gravity fluid curtain 114 cognition moves straight down
Full molten aluminum liquid forms liquid closed space, while the gas for being set to the appendix 2 of fluid passage 11 is flowed through gas passage 21
Gas out contacts with each other with 114 body of fluid curtain, improves the contact area of liquid and gas, and gas is penetrated into liquid, mentioned
High foaming rate and bubble distribution uniformity.
Further, as shown in figure 4, the lower section of fluid passage 11 is arranged in the gas passage 21, which is this reality
Apply one of example mode, its object is to the molten aluminum in fluid curtain 114 due to gravity from top to bottom it is mobile with due to
The gas that self-characteristic moves from bottom to top contacts with each other, and gas penetrates into molten aluminum.
Further, as shown in figure 5, the fluid passage 11 includes the first fluid passage 111 and the lower section of top
Second liquid channel 112, the gas passage 21 are set between the first fluid passage 111 and second liquid channel 112, it is ensured that
The liquid that the gas that gas passage 21 exports downwards can be exported with the second liquid channel 112 of the lower section of the gas passage 21 is abundant
Contact, at the same the gas exported upwards in the first fluid passage 111 since the molten aluminum that gravity moves down comes into full contact with,
Gas penetrates into molten aluminum.
Further, as shown in fig. 6, the perfusion tube 1 and appendix 2 be provided in the axial direction multiple fluid passages 11 and
Gas passage 21 and the setting of both interval, which is one of the present embodiment preferred embodiment, it is intended that really
Gas is protected since self-characteristic freely moves upwards after being exported, while injection liquid is formed multiple fluid passages 11 outward
Fluid curtain 114 meet since gravity moves straight down with the gas freely moved upwards, secondary sufficiently connects
Touching, further increases the frothing percentage of molten aluminum.
Further, as shown in fig. 7, the fluid passage 11 is circumferentially to be arranged to fan-shaped sealing 113 along perfusion tube 1,
Molten aluminum forms fluid curtain 114 through the outflow of sealing 113, increases area of the molten aluminum in course of injection, connects gas with molten aluminum
Touching is more abundant, further improves frothing percentage, which is suitable for the production demanding foaming aluminum of frothing percentage.
Further, as shown in figure 8, the fluid passage 11 is along the circumferentially spaced multiple sealings of perfusion tube 1
113, molten aluminum forms fluid curtain 114 through the outflow of sealing 113, and compared to fan-shaped sealing 113 is arranged to, which reduces aluminium
Area of liquid during ejection, gas contact opposite reduction with molten aluminum, and frothing percentage is relatively low, which is suitable for system
Make frothing percentage foaming aluminum of less demanding.
Further, as shown in figure 9, the gas passage 21 include conduit 211, the conduit 211 one end connection described in
Gas passage 21, the other end is extend out to outside the perfusion tube 1 and its outlet side is arranged in wide-mouth, it is ensured that gas energy in output
Uniformly output around, increases the distributing homogeneity of gas.
Further, as shown in Figure 10, the conduit 211 is circumferentially uniformly arranged along appendix 2, and quantity is at least 4, is increased
The output quantity of atmospheric, it is ensured that liquid can have sufficient gas to contact with each other with it.
It should be noted that a kind of gas contact-type of the present invention, from foamed assembly, the fluid passage 11 of perfusion tube 1 sprays outward
Penetrate molten aluminum and form fluid curtain 114, since the liquid in the gravity fluid curtain 114 can move straight down, make this
Circumferentially be covered with molten aluminum liquid forms liquid closed space to one fluid passage 111, while the gas in appendix 2 is through gas passage 21
Continuously outflow in the liquid closed space of formation and contact with each other with molten aluminum liquid, gas is penetrated into liquid, improve liquid with
The contact area of gas improves frothing percentage and bubble distribution uniformity.
The course of work is as follows:
By fluid passage 11, injection molten aluminum forms fluid curtain 114 outward when perfusion tube 1 has molten aluminum to flow through, due to gravity
The liquid acted in the fluid curtain 114 can move straight down, and the lower section of the fluid passage 11 is made circumferentially to be covered with molten aluminum liquid
Liquid closed space is formed, the gas that appendix 2 flows into continuously outflows in the liquid closed space of formation through gas passage 21
It contacts with each other with molten aluminum liquid, gas is penetrated into liquid, abundant foaming liquid.
