Description
The present invention is a kind of apparatus for liquid aeration, carry the vertical shaft type rotor of air and liquid and the stator of a surrounding rotor layout to form by one, this stator is a closed annulus, it is the orthogonal honeycomb duct that there is the cross section inside, liquid-air mixture passes through in honeycomb duct, the axial plane that the vertical division surface of each of honeycomb duct all intersects with this division surface in an inner periphery scope at stator sets out, towards the oblique extension of the sense of rotation of rotor.
In known this class inflation mechanism (seeing austrian patent specification sheets 269038), by the center air conduit vertically inhaled air pass through uniform mixing with the liquid that sucks equally via rotor axial, radially be thrown out of stator again, stator is made of two annular discs that are certain axially spaced-apart, is provided with vertical flow deflector between these two disks.It is the orthogonal honeycomb duct that vertical flow deflector can be separated out the cross section, and liquid-air mixture can directionally be ejected in the liquid to be inflated by this honeycomb duct, thereby the interior liquid of certain limit reaches inflation equably around making stator.But along with the increase of the distance between liquid and the stator excircle, the inflation effect will weaken, and this is because the jet velocity of liquid-air mixture can reduce along with the increase of this distance.Therefore the diameter that holds the container of aerated liquid just can not surpass certain limit, can both reach even inflation with the whole cross section that guarantees container under given rotor power.
Task of the present invention is, improved with the inflation mechanism of simple means to the above-mentioned type, makes it adopt bigger container section also can accomplish even inflation under given rotor power.
The present invention to the solution of above-mentioned task is, make the adjacent vertical division surface of direct formation honeycomb duct be the excircle of radial sensing stator, and the vertical division surface of each honeycomb duct is parallel mutually, and its maximum deflection angle is 7 °.
Because the measure of having taked to make the vertical division surface of each honeycomb duct to be parallel to each other at least basically and to extend, so that speed and comparing greatly of existing simple guiding wall type stator that liquid-air mixture is discharged from honeycomb duct are improved, do not need to increase simultaneously the power of rotor.The effect that improves liquid-air mixture velocity of discharge is the steam circle that has correspondingly enlarged liquid-air mixture, thereby can accomplish to inflate equably in bigger container section.In addition, above-mentioned measure also can to this device bring structural favourable outside, because the size of rotor and shape are by the volume decision of its air of discharging and liquid, promptly by the decision of claimable inflation rate, the steam circle of the liquid-air mixture of being discharged is then by the structures shape of stator honeycomb duct.The jet velocity of the liquid-air mixture of discharging in stator will be subjected to the influence of honeycomb duct shape.If make the vertical division surface of each honeycomb duct be the excircle of radial sensing stator, then the velocity of discharge of liquid-air mixture just is less than the suction velocity in the stator.If the raising velocity of discharge, just should dwindle the cross section of honeycomb duct towards the outlet end direction, vertical division surface is shunk towards stator excircle direction.Angle between the vertical division surface of each honeycomb duct must not be greater than 7 °, to avoid forming too much eddy current.If eddy current, then the steam circle after liquid-air mixture ejection will significantly reduce.
Should be noted that near two the adjacent distances of the fluid that honeycomb duct sprayed container outer wall when increasing the diameter of container not too big so that guarantee near the even inflation of the liquid outer wall.In order to accomplish that in larger-diameter container the fluid that adjacent honeycomb duct is sprayed is no more than the ultimate range that is allowed, should suitably increase the quantity of honeycomb duct.
Honeycomb duct can adopt the structure of different types.For example, can constitute honeycomb duct, and make dividing plate between the annular disc that two certain axial spacings of one-tenth are arranged with dividing plate.Another kind of reasonable structure is that honeycomb duct is made of the member that is arranged on the U-shaped cross section on the annular disc.This structure is not only easily manufactured, consumable material is few, and is convenient to stator is cleaned, because the tapered region between the U-shaped section structural member of each formation honeycomb duct is an open type.
What represent in the accompanying drawing is embodiments of the invention, wherein
Fig. 1 represents apparatus for liquid aeration synoptic diagram of the present invention, and the part among the figure is analysed and observe;
Fig. 2 represents the vertical view of the stator of inflation mechanism, has done broken section among the figure;
Fig. 3 represents along the profile of Fig. 2 III-honeycomb duct that the III line is done;
Fig. 4 represents similar another kind of honeycomb duct structure a kind of and shown in Figure 3;
Fig. 5 represents the horizontal cross of stator, and the honeycomb duct above it radially distributes;
Fig. 6 represents the stator that similar honeycomb duct a kind of and shown in Figure 5 radially distributes.
According to the example shown in Fig. 1, be directly installed on that inflation mechanism on the container floor 1 mainly is made of rotor 2 and stator 4, its rotor 2 is driven by electric motor 3, and stator 4 is arranged around rotor 2.Vertically disposed rotor spindle 5 passes container floor 1, and is linked together with the electric motor 3 that is fixed on the base plate.Need be charged to air in the liquid and suck by air lead 6 and be introduced into rotor 2 vertically, the liquid in the container also is inhaled into rotor 2 simultaneously by the looping pit on the stator 4, in figure shown in the arrow.
Liquid-air mixture passes honeycomb duct 8 in stator 4, honeycomb duct is made of dividing plate 9 in Fig. 1 to Fig. 3, and dividing plate 9 is arranged between two annular discs 10 and 11.The adjacent vertical partition plate 9 that directly constitutes honeycomb duct 8 is the excircle of radial sensing stator 4, and the vertical division surface of honeycomb duct 8 is parallel to each other.This spline structure can guarantee to make the speed of liquid-air mixture when rotor 2 enters stator 4 to be similar to the speed of fluid from honeycomb duct 8 ejections, because spouting velocity compares higher, therefore the steam circle of fluid in container is also bigger, in order in larger-diameter container, to accomplish even inflation, should arrange the honeycomb duct of sufficient amount, so that make from the unlikely too dispersion of the adjacent fluid that honeycomb duct sprayed near the particularly unlikely too dispersion outer wall of container.
As shown in Figure 4, stator can also adopt a kind of very simple structure, promptly adopts the member 12 of U tee section to make honeycomb duct 8, and 12 of members are contained in above the annular disc 13.This structure is not only made easily, and is convenient to stator is cleaned, because the tapered region between the adjacent honeycomb duct is an open type.
Under the condition of given fluid container diameter and rotor power,, can adopt the vertical division surface of non-flat line to constitute honeycomb duct 8 in order to reach the spouting velocity of the needed liquid-air mixture of inflation in stator.For example allow the dividing plate 9 of honeycomb duct 8 expand towards the direction of stator 4, then the rate of flow of fluids in the honeycomb duct 8 will slow down.Certainly, the angle α between the vertical partition plate 9 must not otherwise can form more eddy current greater than 7 °, thereby can limit the fluidic steam circle of ejection in honeycomb duct 8 widely.
If require fluid in the jet velocity at the excircle place of stator 4 greater than inlet velocity, then should allow the dividing plate 9 of honeycomb duct 8 shrink, as shown in Figure 6 towards the direction of stator excircle.In this case, the angle α between the vertical partition plate 9 also must not be greater than 7 °.
When using aforesaid inflation mechanism, owing to adopted the stator of special construction, so liquid can both be inflated in bigger area equably, such inflation mechanism mainly is applicable to liquid acetic fermentation, occasions such as yeast production or sewage purification.
The aerating device that the present invention is not limited only to introduce among the embodiment. Rotor for example also can be made various shape, liquid can not only be resembled as shown in Figure 1 suck from one side, and can suck from the two sides. Also can adopt other rotor structure, make air from following suction, and make motor into known submersible motor, be installed in the top of rotor. Certainly, also can suck other gases beyond the deacration, and it is charged to arbitrarily among the liquid. According to the difference of rotor structure, honeycomb duct 8 can be chosen different radial skew degree, and can determine according to the diameter of the gradient of honeycomb duct and container the quantity of honeycomb duct. In addition, the adjacent separator 9 that directly consists of honeycomb duct 8 also can be formed by a total spacer block, and its shape is similar to a chock, thereby the vertical division surface that can guarantee each honeycomb duct is parallel to each other basically.
