Definitions
- the invention relates to a solid bowl screw centrifuge according to the preamble of claim 1.
- the generic solid bowl screw centrifuge in such a way that the relative speed of the Spinning material when entering into the liquid surface on structurally simple Way is reduced.
- At least one wall of the distributor with a Surface structure of at least two or more radially offset from each other Provided rows of projections, wherein the projections of the rows to each other in such a way axially offset, that substantially no radial free flow channels are formed on the wall.
- At least one wall of the distributor is so with a surface structure of projections provided that the essential part dea the splitter flowing through centrifugally good at this at least one wall on the substantially radial and / or substantially in the direction of Centrifugal extending distance from the inlet pipe into the centrifugal space at least must flow around one of the projections.
- centrifugal here is the direction to understand the Verteilerwandung in which the centrifuged by turning the Distributor by the centrifugal force substantially flow into the centrifugal space wants, i.
- the term "radial” may also include an axial component of motion and / or a peripheral component. It is important that at least the essential Part of the centrifugal material not directly "in the direction of centrifugal force" in the Centrifugal space flows.
- the projections have a meander shape.
- the projections are formed as sheets.
- At least one Wall of the distributor with a circumferentially extending, staircase-like Surface structure provided, which also a braking, u.a. by Turbulence, causes.
- Fig. 1 shows a solid bowl screw centrifuge with a screw 1, a Screw body 3 and here a worm-like surrounding the screw body 3 Schneckenblatt 5 has. Between the worm threads x, x + 1, ... is a Screw channel 7 for conveying / transporting a centrifugal material to be processed educated.
- Centrifugal S is through the centrally arranged inlet pipe 13 into a manifold 15 and from there through radial openings 17 in the manifold 15 in the centrifugal space 19 with the screw 1 and the screw 1 surrounding drum 21 passed.
- the screw 1 rotates at a speed slightly lower or higher than the drum 21 and conveys the ejected solid F to the tapered portion 11 out of the drum 21 for solids 23.
- Fig. 2 again shows the inlet pipe 13, which projects into the manifold 15, the here has a substantially rectangular cross-section (perpendicular to the image plane 2) or is formed substantially as a rectangular tube.
- Alternative training are of course conceivable, so a training of the distributor as Pipe construction of two intersecting rectangular pipes or pipes, which not perpendicular to the drum axis but at any angle to this aligned are.
- deviating cross-sectional geometries are also of a rectangular cross-section realizable.
- the relative velocity component should be v when entering the sling in the centrifugal chamber 19 as small as be possible, for example, in products which are relatively strong for foaming tend or have sensitive structures, just not as in the state of Technology may be destroyed or damaged (e.g., flocculants that are not to be destroyed).
- the S should therefore ideally only with the Circumferential rotational speed of the screw body 3 and without relative speed v (see also Fig. 12) enter the centrifugal space.
- the walls 15a, d of the distributor which in the opposite Ends of the distributor 15, the centrifuged material substantially during the rotation of the Take distributor 15 - or in addition the vertical side walls 15b (or alternatively also all walls) of the distributor with a surface structure to be provided, which in particular formed directly on the wall 15a, d or on at least one separate, attachable to the wall Sheet 29 formed projections 27 may consist. Also a multilayer arrangement of several superimposed sheets 29 with projections 27 is feasible (Fig. 3).
- the projections 27 distributed.
- the projections 27 are further at least in the radially outer region the distributor wall 15a, d formed. This has the following advantage.
- the projections 27 may also widen away from the wall 15 a or also rejuvenate. Also ball-like shapes are conceivable.
- the extent of the projections 27 perpendicular to the distribution wall 15a is such in each preferred application (e.g., fruit juice recovery etc.) and at maximum throughput of centrifugal the projections 27 at least are as high as the liquid level on the wall 15a.
- the protrusions are about twice as high as the average liquid level.
- the projections may alternatively be formed as rods, which the Distributor 15 from the wall 15a to the opposite wall 15d push through.
- the knobs 27 can also be formed as forms or in others Way directly integrally formed with the wall 15 a, d or the sheet 29 be. This one-piece forming can be done in the casting or by milling the nub structure out of a correspondingly thick wall plate.
- the nubs 27a, b are each arranged in rows, which are parallel to the drum axis A are aligned. The rows are so half of each other Distance between two adjacent nubs 27 a, b axially offset arranged that the Centrifugal S is denied a direct flow in the radial direction. Of the axial distance d of the knobs 27a, b to each other here is slightly larger than that Diameter of the nubs 27a, b. The distance between the centers of the knobs in radial Direction corresponds approximately to their diameter a, b.
- the knobs 27, according to Fig. 2, a radially outwardly gradually smaller Expected diameter.
- the fürströmkanäle 33 are also smaller or narrower. This training causes an increasing braking of the Spin good radially from the inside out, that is, it acts the increasing Acceleration due to the increasing centrifugal force. It will the path to be covered for the goods S to spin around the nubs 27a, b longer.
- the rows of nubs 27a are each about the diameter of Nubs offset from one another, wherein the distance between the centers or Central axes of the cylindrical knobs 27a in each row each have the diameter d of the nubs 27a corresponds.
- Fig. 4e shows a variant in which the nubs of a row such a small Distance from each other, that at an axial offset of the rows of knobs by half the distance between two adjacent knobs no perpendicular to the central axis A centrifuge extending linear flow channels 33 remain.
- Fig. 6a shows a variant of the invention in which instead of rows of nubs at least two rows of sheet metal strips 127 on the wall 15 a of the distributor are attached.
- These metal strips 127 are each aligned at an angle to the central axis A of the centrifuge and are so close to each other in opposite angularly offset In turn, that no flow channels in the radial direction at the Verteilerwandung remain but a strong deflection and deceleration occurs.
- the angle here is about 30 °. The smaller the angle to the central axis, the better the speed must be higher, so that no deposits on the sheet metal strip form. The angle could also be reduced to the outside, possibly to to the value 0.
- a variant shows Fig. 7.
- a first very flat plate 127 leads to strong deceleration into a labyrinth arrangement 128 of further bent sheets 127, which is designed so that again no radial flow is possible.
- the projections have a kind of meandering shape.
- the zigzag-like Meander 327 engage each other in such a way that again no flow channels radially remain outside in the distributor 15.
- the sheets 428 have an angular cross-section, i. they each consist of one substantially parallel to the distribution wall extending portion 428a and an angled section 428b, which here exemplifies an inclination of about 30 ° to the vertical on the distributor wall has.
- the section 428a extending substantially parallel to the distributor wall of the first sheet 428 is placed directly on the distributor wall.
- the parallel to the distribution wall 428 a extending portions of the following plates 428 are respectively at the backsides of the angled portions 428b of the preceding panels attached so that between the successive sheets 428 a kind Verwirbelungsraum arises.
- the liquid jet hits from one step or sheet 428 to the next Step or the next sheet 428, he (in Fig. 9 to the left and right) in the flow direction and directed and swirled against it in different directions, which in turn causes a braking effect.
- FIG. 10 differs from FIG. 9 not only in that the step construction 427 was realized in one piece from a cast or milled part, but that the step construction is designed such that the substantially parallel to the distribution wall extending portion 429a of the steps 429 respectively at the ends of Angled portions 429b of the preceding stage connects, so that between the successive stages no turbulence space arises.
- FIG. 11 An alternative to FIGS. 9 and 10 is shown in FIG. 11.
- a kind of "waterfall brake feed” is shown.
- the individual stages 430 will again be essentially through formed parallel to the drum axis extending rows of protrusions 431 or in a plate grooved rows 432 are milled.
- the rows of grooves 432 have again an angled cross section, i. they each consist of one substantially parallel to the distributor wall extending portion 432a and an angled section 432b, which here by way of example has an inclination of about 30 ° to the vertical on the distributor wall has.
- the respectively essentially parallel to the distribution wall extending portions 432a of the rows of grooves are substantially aligned with each other, that is, they lie in one plane, which is the production compared to the variant of FIG. 10 cheaper (less waste during milling or less casting material required). It is advantageous in the case shown here
- the inclined portion 432b makes an angle of about 30 ° to the vertical on the Verteilerwandung and that the impact of the liquid jet to the next stage also at an angle of e.g. 30 °.
