Definitions
- the invention relates to an agitator, in particular a Fumigation stirrer for stirring liquids, which a gas, for example air, is supplied according to Preamble of claim 1.
- a gas for example air
- a stirrer of the type mentioned above is known from US-A-5,198,156 or US-A-4,779,990.
- one of the The gas supplied to the stirring liquid is as small as possible Bubbles dispersed to a large surface for the Mass transfer between the gas and the liquid too create.
- Such a gassing stirrer usually includes one Disc stirrers with stirring blades and an annular one Gas distributor, circular along its apex Holes are formed that keep the gas rotating Feed disc stirrer, the shear effect of which Gas is further dispersed.
- the stirrer By the rotational movement the stirrer is created on the back of the Stirring blades a negative pressure, which is there to form Gas cushion leads.
- These gas cushions give the stirring blades a more aerodynamic contour, which is in a sharp drop in performance at a given speed expresses.
- the invention is based on the object Stirring device to create these disadvantages mentioned above at least essentially eliminated.
- a stirring element is provided for this purpose, which has the features of claim 1.
- FIG. 1 shows a top view of a stirring element 10 with a hub 12 for fastening the stirring element 10 to a not shown Agitator shaft.
- the Agitator 10 has a central axis 32. This rotates during operation Stirring element 10 in the direction of arrow P around the stirrer axis central axis 32.
- the level of rotation or stirring level 30 lies transversely to the stirring axis 32.
- the support disk 14 is conical, the fictitious cone tip expediently in the Stirring axis 32 lies.
- the support disk 14 can also in other ways, for example graded, conical or curved, as long as below it the cavity 36 is formed.
- FIG. 2 shows, there is a supply pipe 28 for the gas supply in the Cavity 36 introduced, the mouth 38 conveniently below the fictitious cone tip and concentric to the stirring axis 32 lies.
- the support plate 14 is on its outer Circumferential edge 40 with, in particular, triangular prongs 26 provided that apart from the attachment points of the stirring blades 16 along the entire circumference of the support disk 14 run.
- the prongs 26 are expediently in the surface of the cone shell 34 (or form part of this), they but can also up or down relative to the cone shell 34 be turned.
- prongs 26 forming a ring of peaks are uniform Gas leakage and improve the dispersion of the over the Feed pipe 28 in the cavity 36 introduced gas, or with in other words, they help break up the gas bubbles.
- Figure 3 shows a plan view of the blank, that is given sheet metal blank of a stirring blade 16 before this in his Operating form is bent.
- the blank 42 is approximately trapezoidal in shape and has on its outside (related to the later working position) one Width B1 of, for example, 40mm and one on the inside Width B2 of, for example, 50mm.
- the radial length L1 of the Blank 42 is, for example, 37 to 38mm. (Of course the invention is not based on this only as an example mentioned dimensions.)
- the blank 42 becomes wedge-shaped along its center line 44 bent such that the two legs 18 and 20 of the wedge enclose an angle ⁇ , as shown in FIG. 4.
- the wedge angle ⁇ expediently lies approximately in the range from 45 ° to 75 °, and he is preferably about 60 °.
- End sections 22 and 24 of the two legs 18 and 20 are longitudinal of the bending lines 46 and 48 and based on that in FIG. 3 shown position of the blank 42 upwards by an angle ⁇ ( Figure 4) bent.
- the angle ⁇ between the respective end section 22, 24 and its associated leg 18, 20 is expediently in Range from about 120 ° to 160 ° and is preferably about 140 °.
- the end sections 22, 24 are essentially triangular formed, and their width increases in the radial direction from the The outside of the stirring blade is towards the inside of the stirring blade.
- On the inside of the stirring blade 50 in this example is the width B3 End section 22, 24 about 12.5 mm, but this dimension only is an example to which the invention is not limited.
- the Length L2 of the end sections 22, 24, measured from the inside of the stirring blade 50 off, can expediently about two thirds to amount to three quarters of the radial length L1 of the stirring blade 16, while the width B3 of the end portions 22, 24 on the inside of the stirring blade 50 about 20% to 30%, preferably about 25%, the total width B2 of the stirring blade blank 42 can be.
