Definitions

  • the invention relates to a self-draining separator with disc package according to the preamble of claim 1.
  • Self-emptying separators with disk packs which, for example, have a piston slide or the like for emptying, are known per se in a wide variety of embodiments. They are used in different types of centrifuges, e.g. Used in clarifying, separating or sterilizing centrifuges for a variety of purposes.
  • the preferred area of application is the processing of dairy products and in particular the sterilization and skimming of milk.
  • the invention has the object to improve the structural design of the separator in the generic way such that an improved cleaning effect can be achieved.
  • the drum has Feststoffaustragsöffhungen and the Ab ⁇ stood between the ribs - or the advantageous realized rib insert - and the inner wall of the drum is at least three millimeters at each point.
  • an annular gap of at least 0.5 mm, but not more than 5 mm, is formed between the ribs and the plate pack in order to sufficiently clean this region as well.
  • the ribs cover at least 5 percent but not more than 95 percent of the cross-sectional area of the solids space in order to always ensure a sufficiently large cleaning effect.
  • fer ⁇ ner advantageous if the outer diameter of the ribs at least 1 mm, but at most 25 mm larger than the diameter of the separator plate.
  • the center of gravity of the rib surface should preferably be above the drainage level.
  • this center of gravity below the emptying level, but this leads to less advantageous results.
  • the rib surfaces are provided with compensation openings. These relieve the ribs in Trommelent ⁇ emptying advantageously of tips of the Coriolis horres.
  • the ribs are combined by connecting elements to form an annular insert, which facilitates the assembly and disassembly of the ribs as a unit.
  • This rib insert is also preferably fixed in position by support elements which are integrated in the telescope package.
  • the rib insert for fixing is preferably firmly connected to the separator plate - if present.
  • Figures 1 to 6 are schematic sectional views of a portion of a erfin ⁇ to the invention separator drum;
  • Figure 7 is a schematic representation of the design of ribs according to a particular embodiment of the invention.
  • Figure 8 is a schematic representation of a rib insert in one
  • Figure 1 shows a highly schematic illustrated drum 1 for an otherwise not with regard to its other components such as the drive and the like.
  • separator with a vertical axis of rotation D, wherein the drum um ⁇ a centrifugal space 2 borders, in which a plate package 3 of a plurality of conical plate 4 is inserted, in which one or more riser channels 5 are formed.
  • the centric inlet pipe 6 opens from here initially from above into a distributor 7, which has channels 8, which conduct the material to be centrifuged outwards as far as exit openings 9 into the centrifuging space 2.
  • the outlet openings 9 can be arranged at different radii, preferably on those radii which lie shortly before or within or after or outside the outer circumference of the plates 4.
  • the drum has Feststoffaustragsö réelleen 10, which are preferably at the largest diameter of the drum and which preferably a piston slide (not shown) is connected upstream.
  • a piston slide (not shown) is connected upstream.
  • To realize the self-emptying function or to open and close the solids discharge openings 10 can serve, for example, a not shown here spool.
  • At least one discharge channel 11 which may be followed by a paring disc, allows the discharge of a liquid phase from the centrifugal space 2.
  • the drum 1 has a drum base 12 and a drum shell 13, or the like via a locking ring 14. are firmly connected.
  • a rib insert 16 (see FIG. 8) with a plurality of ribs 17 is arranged in the radially outwardly tapering ring or solid space 15, the ribs 17 being joined to the insert 16 by connecting elements 18, 19.
  • the insert can be fixed in its position by supporting elements that are integrated in the plate package (not shown here). Also, the insert is spaced at any position at least 3 mm from the drum inner wall
  • the rib insert 16 is firmly fixed in the solid space 15 in its position.
  • the ribs can be directed radially outwards or, with regard to the direction of rotation (R) - see FIG. 7 - in particular up to 45 ° inclined to the radial r (angle ⁇ ) can be aligned leading or lagging.
  • Such a particularly advantageous cleaning effect is achieved because it is ensured that always a sufficiently large cleaning effect in the solid space 15 is achieved because at all points between the ribs 17 and the drum 1 is always a sufficiently large flow at critical points and in particular at the On the outer peripheral surfaces in all peripheral regions of the centrifugal space, a relatively large relative movement of the fluid relative to the drum in the circumferential direction is allowed.
  • FIG. 1 shows a variant in which the ribs 17 cover a large part of the cross section of the solids space, in particular up to 95 percent of the cross section of the solids space 15.
  • the outer diameter D A of the ribs is at least 2 mm and a maximum of 25 mm larger than the diameter D 5 of the separator plate 23rd
  • FIG. 3 illustrates that the center of gravity Pl of the rib surfaces lies above its plane of action, which is determined by the solids discharge opening 10.
  • FIG. 4 illustrates a corresponding variant in which this center of gravity P2 of the ribs is arranged below the plane of the solids discharge opening 10.
  • FIG. 5 illustrates further connecting elements (eg rings) 20, 21 for connecting the ribs 17 to one another.
  • FIG. 6 shows that the ribs can be provided with openings 22 in order to relieve the rib areas 17 of the ribs 17 at the solids discharge of peaks of the Coriolis pressure.
