Description

Bubble generator and its use

The present invention relates to a kind of gas, two kinds of materials mixing of liquid, generate the bubble generator of bubble.

Almost everyone plays over-blowing recreation lathery.Get a short tube, in filling the container of liquid soap, dip in liquid, make the mouth of pipe form liquid film, blow with mouth, the mashed soap bubble of seven variegation just occurs from the other end of pipe.This arm and container are exactly the simplest bubble generator.But this ancient and simple device does not have other practical value except that being used as toy.

In fact, for a long time, the mankind make unremitting effort to the technological improvement of bubble generator, progressively are applied aborning.The third phase in 1971 " metallurgical security " is translated the bubble generator that is loaded with pass " waterpower injection type foaming machine ".Its objective is and utilize this device to produce foam continuously in a large number, suppress mine dust.Its structure is that control valve, water jet fan are connected with the foam maker that grid is made, and liquid feeding channel is communicated with the expanding foam solution case with water jet fan then.Its foam theory is, the air-flow through control valve is regulated produces negative pressure in water jet fan, draws the liquid and the atomizing of expanding foam solution case, carried by air-flow, and vaporific liquid is splashed on the foam maker grid.Form liquid film in the grid gap, air-flow blows liquid film and swashs into foam.This device has solved additional expanding foam solution problem effectively, makes it industrial practicality arranged.But under the situation of air current flow, vaporific liquid is difficult to form liquid film in the grid gap, usually can wear net and mistake.Form in order to help liquid film, it is big that the expanding foam solution consumption is wanted, and the grid gap is little, and this not only can too much consume expanding foam solution, and the bubble diameter that generates also is restricted.In fact, what this device produced is the foams that the numerous air-bubble adhesion forms, rather than the bubble individuality that disperses.And foaming part is placed apart with container, operates and carry all inconvenient, and therefore, the use of this device is restricted widely.

The objective of the invention is provides a kind of bubble that can recur to the public, and foam device be whole with the container of dress liquid, carries with easy to operate, can use multiple liquid charging stock, and a kind of bubble generator that is widely used in production.

The present invention realizes by following technological approaches.Utilize liquid in container, under the effect of externally air inlet, the outer surface pressure of liquid level upward pressure and container is different, and promptly the liquid level upward pressure is greater than the outer surface pressure (normal atmosphere (An)) of container, and liquid is just outwards run out of from the airtight container gap.Liquid forms the principle of bubble in the exit under the air-flow effect, through meticulous calculation Design, with the container of dress liquid make with scientific and reasonable the connecting of the tracheae that has vapour lock (assembling) together.Vapour lock is meant the mechanism or the element that can hinder gas flow, generally all has the narrow geometric properties of section, and is for example cone-shaped.

The present invention is a kind of simple in structure, carries or moves conveniently, and cost is low, and purposes is wide, effective bubble generator.

Below in conjunction with accompanying drawing structure of the present invention is elaborated.

By Fig. 1,5,8,10 as can be known, bubble generator is made up of container 2, vapour lock 1, tracheae 3, gas passage 4, liquid feeding channel 5, dress liquid mouth 6, seal cover 7, bubble outlet 10. Open dress liquid mouth 6 on the chamber wall, be stamped seal cover 7 on its mouthful. Vapour lock 1-end is equipped with tracheae 3, and the other end is bubble outlet 10. Form current path. Near vapour lock both

sides interface channel

4,5, passage is to make container in parallel with the tracheae with vapour lock, forms gas, liquid glide path. Gas passage 4, liquid feeding channel 5 can be by hollow pipe, also can be that the gap communication that boring on tracheae, staking or utilization are connected with vapour lock forms. Be used for the passage 4 of air inlet near the narrow section parts of vapour lock, be used for the passage 5 of feed flow near exits, passage 4 is greater than passage 5, and it is much smaller to cause air to enter the resistance of resistance ratios liquid outflowing container of container. Consist of foamed system by bubble outlet, vapour lock, tracheae, passage, sealing is placed in the lower inside of container, is immersed in the expanding foam solution. The air inlet mouth of pipe and bubble outlet are exposed at outside the container, are sealed fixing by chamber wall. As required, container can be made various shapes, and with moulding and Spanish furnish. Apparatus of the present invention utilize the curved liquid surface additonal pressure can effectively overcome the expanding foam solution leakage problem. This is because the passway is immersed under the expanding foam solution, and leakage is because channel outlet has discrepancy in elevation △ h, therefore has gravitional force, so that high bit port air inlet, low bit port leakage. The present invention does channel outlet narrow, so that gas that channel outlet forms, liquid interface curvature radius are enough little, the curved liquid surface additonal pressure is enough big, is enough to overcome gravitional force, thereby prevents the leakage of expanding foam solution.

Below further combined with the embodiment of different purposes structure of the present invention is elaborated again.

Fig. 1 has provided and has made a kind of bubble generator that children play the usefulness that froths.As seen from Figure 1, container 2 is a squirrel shape attractive in appearance, draws your jet tube vapour lock 1 of valve to be enclosed within on the tracheae 3, fixes by chamber wall.Draw your jet tube vapour lock of valve to be horn-like, it is the tubule of 0.4mm that at least one (in this example being 16) interior diameter is equipped with in the exit, constitutes liquid feeding channel 5.Pipe can be adjusted its length according to different expanding foam solutions, sees that the A-A section is shown in Figure 2.As required, also can be designed to one group and produce 18mm, the 12mm of different bubble diameters, the jet pipe of 6mm.The aqueous solution with surfactant 2% is done expanding foam solution, sends the bubble that has seven glory spots.Outlet A-A cross section interior diameter d1 is 12mm, 8mm, 4mm, section B-B diameter d 2 is 2mm, 1.47mm, 0.874mm, C-C cross section vapour lock mouth diameter is 8mm, and TD is 3.36mm, and the space forms concentric circles skew wall annular space form gas passage 4 between vapour lock mouth and the tracheae.The pipe of band vapour lock is contained under the container inner, is immersed in the foaming, sees to have only container and tracheae, bubble to export from appearance.This device uses different expanding foam solutions, can produce different bubbles.Open dress liquid mouth 6 on the chamber wall, its loam cake seal cover 7, whole device materials is made with nontoxic thermoplastics type's rigid plastics or metal.Concrete foaming process is, connect source of the gas (mouthful time or air feeder etc. all can), bubble outlet, vapour lock and tracheae constitute a current path (straight-through road), on it and be connected with a closed branch road, and divide the gas passage 4 of flowing through to enter container before the chord route vapour lock, again after liquid feeding channel 5 flow containers meet at vapour lock.Air flow stream is crossed current path, because the vapour lock effect makes air-flow produce pressure and falls, promptly pressure reduction △ P occurs at A-A section and C-C section.Therefore pressure reduction △ P, has a small gangs of air-flow to enter the container aggregation on liquid level top through gas passage 4 for parallel branch provides the power of shunting, and container inner pressure is raise, and forces expanding foam solution to flow to section A-A through liquid feeding channel 5.As long as the air communication mistake is arranged, just there is pressure reduction △ P to produce, as long as pressure reduction is arranged, just there is expanding foam solution to carry.When not having air-flow, pressure equals atmospheric pressure P in the container, and when pressure is the air flow stream of PS when crossing current path, section C-C pressure is PS, and section A-A pressure is PS-△ P.As previously mentioned, on parallel branch, what flow into container is gas, flow container be liquid, gas, two kinds of material densities of liquid and viscosity differ very big, gas passage 4 is greater than liquid feeding channel 5 in the design.Be approximately zero so flow into container gas passage 4 resistances, flow container passage 5 resistances are relatively very big, are approximately equal to △ P, and the approximate PS that waits of pressure greater than the outer pressure P of container, forces container elastic expansion distortion in the container.At this moment cut off source of the gas, pressure drop is to P in the container, and the container of dilatancy will shrink, the gas of aggregation will expand in the container, because the passway is immersed under the expanding foam solution, will squeeze container at the narrow section part formation of vapour lock liquid film through passage by liquid, finishing just, film forms function.Just film forms stopping air-flow moment and finishes automatically, and it is ready to generate bubble for blowing next time.Blowing does not first have first film, can of short durationly blow, after this just can normally use.Dynamically be described below: connect source of the gas, air-flow flows through vapour lock along current path, and established film is just shifted onto outlet by air-flow in vapour lock throat, and meanwhile, owing to the effect of vapour lock to air-flow, section C-C and section A-A form pressure reduction.Voltage rise height in the container, the container dilatancy.Parallel branch begins to carry expanding foam solution.Under air-flow continuation effect, liquid film is given prominence to the mouth of pipe, becomes the cylindric liquid film bag of continuous elongation.Because the viscosity of expanding foam solution, gravitation between the surface tension equimolecular pulls to the liquid film bag with mouth of pipe liquid, replenishes the needs of liquid film elongation.Like phase (C.V.BOYS) cylinder liquid film experiment according to Bao, when cylinder liquid film length is 1.5 times of diameter, liquid film is in extremely unsettled critical condition, interference is arranged slightly, and the just rapid examples of neck-bonded of liquid film post is isolated a bubble, air-flow continuation effect, liquid film bag after the separate bubbles continues elongation, constriction, separate bubbles more again ...Parallel branch is replenished expanding foam solution continually, like this also gassing continuously; If stop to blow, pressure reduces in the container, and the container of elastic expansion will shrink, and aggregation will expand at the gas on container top, so small amount of foaming liquid is squeezed vapour lock, the throat narrow in vapour lock forms liquid film, and is ready for blowing into bubble next time.
