Definitions
- the invention relates to a separator with vertical axis of rotation after the Oberbe handle of claim 1.
- Such a separator is from the DE 10 2004 038 613 A1 known. As described in this document, it comes in a use of separators for the sterilization of milk may lead to short-term worsening of the sterilization efficiency due to pressure increases in the inlet, the z. B. caused by partial discharges, tank switching or by an increased air content in the product. Another problem is the transport (shaft run) of germs to the peeling disk.
- connection holes are provided to an annular space which is formed above the free end of the inlet pipe in the manifold, that the connecting bores between a preferably conical inlet space and the annular space, and that the outlet openings from the inlet space in the inlet bores of the distributor and the connecting holes to the annular space is assigned in each case a rib.
- the ribbed body is easy to assemble.
- the inlet pressure can be reduced and the feed rate increased. This results in a gentler Product feeder in the distributor.
- the risk of deposits forming in the inlet area is reduced.
- one or more of the axis of rotation is aligned, which means a strong acceleration of the centrifuged material in the circumferential direction. But it is also conceivable to make them relative to the respective radial, for example, between 1 ° and 80 °.
- the ribs may be straight, but also curved. It is also conceivable a blade-like design with curvatures in all directions, as long as an acceleration effect is given in the circumferential direction.
- FIG. 1 shows a simplified representation of a portion of a rotatable about a rotation axis D centrifugal drum 1 of a continuously operable separator, in which a plate package 2 is arranged from a plurality of plates 3 concentric with the machine axis or axis of rotation D.
- the centrifugal drum is here twice conically formed inside.
- the plates 3 have a conical shape, are stacked axially one above the other and by means of spacers, not shown here (tabs and the like.) Distance from each other.
- the plate package 2 is held on a distributor shaft 4 of a distributor 5, which is provided on its outer periphery with radially outwardly projecting webs (here not visible), which engage on the inner circumference of the plate 3 in this.
- the plate package 2 has riser channels 6, which consist of directly superimposed holes in the plates 3 and extend over the entire height of the plate package 2.
- An inlet pipe 7 lying concentrically to the machine axis makes it possible to feed a centrifuged material from above into the centrifugal drum 1 and through the distributor shaft 4 and below the plate package 2 in the distributor 5 into the plate package 2, for example in the region of the riser channel 6 or on another place.
- solids for example for sterilization
- separation of the product into different liquid phases which are separated by one or more discharges 9, possibly at different diameters, e.g. by peeling discs (not shown here) and solid discharge openings 10 are derived from the centrifugal drum 1.
- the solids discharge openings 10 are preceded by a piston slide 11, which is vertically movable and with which the solids discharge openings can be opened and closed.
- a product supplied through the inlet pipe 7 first enters from the inlet pipe 7 into an inlet chamber 12 in the center of the distributor shaft 4, the free lower outlet of the inlet pipe 7 extending below the upper edge of the inlet chamber 12.
- the distribution channels 8 begin in the peripheral wall 13 of the inlet pipe.
- the inlet chamber 12 is after Fig. 1 designed such that in him a rib body 14 with one or preferably more ribs 15 is used.
- the ribbed bodies 14 are rotatably connected to the centrifugal drum, preferably with the distributor 4, connected.
- FIG 3 and 4 two suitable ribbed bodies 14 are shown in FIG 3 and 4 shown.
- the illustrated ribbed bodies 14 each have a base portion 16.
- This base portion 16 is preferably formed as a circumferentially closed ring portion ( Fig. 1 ' . Fig. 2 ).
- annular base portions 16 formed flat, so that they extend in the installed state perpendicular to the axis of rotation D, after Fig.1 it extends vertically, according to Fig. 2 the base portion 16, however, is conical.
- the base portion 16 is rotatably connected respectively to the rotating system, in particular to the distributor 4.
- the shape of the base portion 16 preferably corresponds in each case to the shape of the distributor 4 in a corresponding contact or support area.
- the ribs 15 project vertically vertically and when installed, they are also vertically aligned.
- the base portions 16 of the embodiments of the 3 and 4 are preferably aligned vertically downwards, so that the ribs 15 project vertically upwards into the inlet space 12.
- the ribs 15 of the embodiments are formed integrally with the base portion 16 and project from one axial side thereof vertically.
- the ribs 15 are formed circumferentially distributed on the base body 16.
- the radial length of the ribs 15 preferably corresponds at least to the vertical height of the inlet openings 17 in the distribution channels 8.
- the ribs 15 are aligned according to a variant radially to the axis of rotation D ( Fig. 3, Fig. 4 ). You can also - see Fig. 2 - be aligned at an angle to the radial direction.
- the ribbed body 14 is inserted or installed in the annular space 12.
- a bore-like inlet opening 17 from the inlet chamber 12 in the inlet bores or - channels 8 is formed or arranged.
- the ribs are located radially inward to the inlet openings 17th
- the rib body 14 as a whole or as a single element in the assembly of the centrifugal drum is easily settable in the inlet chamber 12, where it is fixed against rotation on the manifold 4, which is e.g. by fastening means such as screws, bayonet-like, by shitting or the like. Can be done.
- the inlet chamber 12 is designed such that it adjusts a pressure increase in relation to a configuration without ribbed body 14 in operation.
- the inlet pipe 7 has a disc portion 18 (a "hydro disc"), which after Fig. 1 advantageous - but not mandatory - is formed at the vertical lower end of the inlet pipe 7, where it extends from the inlet pipe 1 perpendicular to the axis of rotation D or perpendicular to the axial direction of the inlet pipe 7 outwardly to the inner circumferential wall of the manifold 4.
- the remaining gap is preferably less than 10 mm, more preferably less than 7 mm.
- a radially inwardly projecting lug 24 at the upper end of the distributor forms an additional closure in operation radially upwards.
- the incorporation of the ribbed body reduces the inlet pressure, e.g. at 80000 1 / h feed rate by 0.5 bar.
- the feed rate can be increased accordingly.
- Fig. 2 becomes a largely too Fig.1 realized analog structure, but the ribs 15 are not radially aligned here but inclined obliquely to the radial, so that the ribs with the respective radials form an angle.
- the base portion 16 is conically shaped so that it can be placed on a corresponding conical portion 19 of the manifold, wherein the vertically extending from the base portion upwardly extending ribs 15 also follow the conical shape of the base portion 16.
- the annulus 12 is after Fig. 2 at least in the region in which the ribs 4 are formed, also conical.
- This pipe section 20 is in its upper vertical region in which the inlet pipe 7 terminates here in a preferred embodiment slightly conical and cylindrical in the adjoining lower portion, wherein the Diameter in this area preferably corresponds to the diameter of the inlet pipe 7.
- the inner diameter is preferably not more than 10 mm, preferably not more than 7 mm, larger than the outer diameter of the feed pipe 7.
- the inlet pipe 7 extends axially in turn into the inlet region of the distributor 4th
- this disc portion 18 is preferably not formed at the free axial end of the inlet tube 7 but a piece in front of its axial end.
- the disc portion 18 extends radially into an annular space 21 extending vertically above and below the disc portion 18 radially beyond the outer periphery of the disc portion 18 extends inwardly.
- the annular space 21 connects vertically to the pipe section 20 of the distributor.
- ribs 23 (preferably at least partially aligned radially) at the upper edge of the annular space on a rotatably connected in operation with the distributor ring 25 or other rotating in operation machine part formed in the annular space in the circumferential direction in the Take operation and thus help that a radial fluid level in the annular space 21 can form.
- vertical ribs 22 may be formed on the disc section 18.
- a liquid ring forms in the annular space 21 on the outside, which closes the inlet area vertically downwards.
- the inlet pressure can be reduced and the feed rate increased.
