Limitation.
As shown in figure 1, a kind of gas contact-type is from foamed assembly, including:
Woven hose 1, fluid passage 11 is provided with the woven hose 1;
Appendix 2, the appendix 2 are arranged at the inside of woven hose 1 and are coaxially disposed with the woven hose 1, the gas transmission
Gas passage 21 is provided with pipe 2;
The fluid passage 11 and the in the vertical direction of gas passage 21 are gentle by the fluid passage 11 in setting up and down
21 outside conveying aluminum liquid of body passage and gas, aluminium liquid and gas contact with each other during ejection.
It should be noted that when there is liquid to flow through the woven hose, the fluid passage 11 of woven hose 1 injection aluminium liquid is formed
Fluid curtain 114 moves straight down because the Action of Gravity Field fluid curtain 114 is known from experience, and makes the circumferential cloth in the lower section of fluid passage 11
Full aluminium liquid liquid forms liquid closed space, while the gas for being arranged at the appendix 2 of fluid passage 11 flows through gas passage 21
The gas gone out contacts with each other with the body of fluid curtain 114, improves the contact area of liquid and gas, and gas penetrates into liquid, carried
High foaming rate and bubble distribution uniformity.
Further, as shown in figure 4, the gas passage 21 is arranged on the lower section of fluid passage 11, which is this reality
Apply a kind of mode in example, its object is to the aluminium liquid in fluid curtain 114 due to Action of Gravity Field from top to bottom it is mobile with due to
The gas that self-characteristic moves from bottom to top is contacted with each other, and gas is penetrated into aluminium liquid.
Further, as shown in figure 5, the first fluid passage 111 of the fluid passage 11 including top and lower section
Second liquid passage 112, the gas passage 21 are arranged between the first fluid passage 111 and second liquid passage 112, it is ensured that
The liquid that the gas that gas passage 21 exports downwards can export with the second liquid passage 112 of the lower section of the gas passage 21 is abundant
Contact, at the same the gas exported upwards with the first fluid passage 111 because the aluminium liquid that Action of Gravity Field moves down fully contacts,
Gas is penetrated into aluminium liquid.
Further, as shown in fig. 6, the woven hose 1 and appendix 2 be provided with the axial direction multiple fluid passages 11 and
Gas passage 21 and both interval settings, the embodiment is a kind of preferred embodiment in the present embodiment, it is intended that really
Protect gas freely motion upwards, while multiple fluid passages 11 outwards spray liquid and formed after being output due to self-characteristic
Fluid curtain 330 met because Action of Gravity Field moves straight down with the freely gas that moves upwards, secondary fully connects
Touch, further improve the frothing percentage of aluminium liquid.
Further, as shown in fig. 7, the fluid passage 11 is along the circumferentially disposed sealing 113 into sector of woven hose 1,
Aluminium liquid forms fluid curtain 114 through the outflow of sealing 113, increases area of the aluminium liquid in course of injection, gas is connect with aluminium liquid
Touch more fully, further increase frothing percentage, the embodiment is applied to make the foaming aluminum that frothing percentage requires high.
Further, as shown in figure 8, the fluid passage 11 is along the circumferentially spaced multiple sealings of woven hose 1
113, aluminium liquid forms fluid curtain 114 through the outflow of sealing 113, and compared to the sealing 113 for being arranged to sector, which reduces aluminium
Area of the liquid during ejection, gas contact relative reduction with aluminium liquid, and frothing percentage is relatively low, and the embodiment is applied to system
Make the less demanding foaming aluminum of frothing percentage.
Further, as shown in figure 9, the gas passage 21 includes conduit 211, described in one end connection of the conduit 211
Gas passage 21, its other end is extend out to outside the woven hose 1 and its outlet side is set in wide-mouth, it is ensured that gas energy in output
Uniformly exported to surrounding, increase the distributing homogeneity of gas.
Further, as shown in Figure 10, the conduit 211 is uniformly arranged along appendix 2 is circumferential, and quantity is at least 4, increases
The output quantity of atmospheric, it is ensured that the gas that liquid can have abundance contacts with each other with it.
It should be noted that a kind of gas contact-type of the utility model is from foamed assembly, the fluid passage 11 of woven hose 1 to
Outer injection aluminium liquid forms fluid curtain 114, because the liquid in the Action of Gravity Field fluid curtain 114 can move straight down, makes
Circumferentially be covered with aluminium liquid liquid forms liquid closed space to first fluid passage 111, while the gas in appendix 2 leads to through gas
Road 21 continuously outflows to be contacted with each other in the liquid closed space of formation with aluminium liquid liquid, and gas is penetrated into liquid, improves liquid
The contact area of body and gas, improve frothing percentage and bubble distribution uniformity.
The course of work is as follows:
Aluminium liquid is outwards sprayed by fluid passage 11 when the aluminium liquid that woven hose 1 has flows through and forms fluid curtain 114, due to gravity
The liquid acted in the fluid curtain 114 can move straight down, the lower section of the fluid passage 11 is circumferentially covered with aluminium liquid liquid
Liquid closed space is formed, the gas that appendix 2 flows into is continuously outflowed through gas passage 21 in the liquid closed space of formation
Contacted with each other with aluminium liquid liquid, gas is penetrated into liquid, abundant foaming liquid.
The foregoing description of the disclosed embodiments, make those skilled in the art do not depart from it is of the present utility model spirit and
In the case of scope, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, of the present utility model
Under teaching, these features and embodiment can be modified new without departing from this practicality to adapt to particular situation and material
The spirit and scope of type.Therefore, the utility model is not limited to the particular embodiment disclosed, and falls with the application
Right in embodiment belong to the scope of protection of the utility model.
