Definitions
- the invention relates to a self-draining separator with disc package according to the preamble of claim 1.
- Self-emptying separators with disc packs for example, have a piston valve or the like for emptying, are known per se in various 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 Feststoffaustragsö réelleen and the distance between each of the ribs - or the advantageous realized rib insert - and the inner wall of the drum is at least three millimeters at each point.
- the state of the art still the DE 567 665 , the DE 444,573 , the US 2,662,687 and the US 2,313,541 called. These documents each show Kammerseparatoren with rib inserts outside of the disk pacts, but no Feststoffaustragsö réelleen, so that the advantages of the invention can not arise.
- the US 2,477,982 shows a self-draining separator with outlet openings without spool, with ribs outside the plate package in turn extend to the drum lid.
- the US 5,735,789 shows a separator with a disc package with rib-shaped spacers.
- an annular gap of at least 0.5 mm, but a maximum of 5 mm is formed between the ribs and the plate package in order to sufficiently clean this area 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.
- the outer diameter of the ribs at least 2 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 emptying plane.
- 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 drum discharges advantageously of peaks of the Coriolis pressure.
- 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 plate package.
- the rib insert for fixing is preferably firmly connected to the separator plate - if present.
- FIG. 1 shows a highly schematically illustrated drum 1 for an otherwise not with regard to its other components such as the drive and the like. shown separator with a vertical axis of rotation D, wherein the drum defines a centrifugal space 2, in which a plate package 3 is inserted from a plurality of conical plate 4, in which one or more riser channels 5 are formed.
- the terms such as “top”, “bottom”, “front” or “rear” and the like. refer only to the illustrated schematic embodiments and are not intended to be limiting.
- the inlet pipe in alternatives, not shown embodiment also be carried out from below the drum, although in FIG. 1 a variant is shown, in which the inlet pipe is guided from above into the drum.
- the centric inlet pipe 6 opens from here initially from above into a distributor 7, which has channels 8, which conduct the centrifuged material outwards as far as the outlet openings 9 into the centrifugal space 2.
- the outlet openings 9 can be arranged at different radii, preferably on such radii, which lie just before or within or after or outside the outer periphery of the plate 4.
- the drum has Feststoffaustragsö réelleen 10, which are preferably at the largest diameter of the drum and which preferably a piston valve (not shown) is connected upstream.
- a piston valve (not shown)
- 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.
- FIG. 2 which is shown simplified, so that the inlet pipe and the channels and outlet openings of the distributor are not shown, it is still possible to derive a second liquid phase via a separator plate 23 (outer diameter Ds) from the drum.
- 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 ribbed insert 16 (see FIG. 8 ) arranged with a plurality of ribs 17, wherein the ribs 17 are combined by connecting elements 18, 19 to the insert 16.
- the insert can be fixed in position by support elements which 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 for fixing fixed to the cutting plate 23 of the FIG. 2 connect to.
- the ribs can - as in FIG. 8 recognizable - be directed radially outward or with respect to the direction of rotation (R) - see FIG. 7 - In particular up to 45 ° inclined to the radial r (angle ⁇ ) 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 outer peripheral surfaces in all edge regions of the centrifugal space a sufficiently large relative movement of the liquid is allowed relative to the drum in the circumferential direction.
- FIG. 1 shows a variant in which the ribs 17 cover a large part of the cross section of the solid space, in particular up to 95 percent of the cross section of the solid space 15.
- the cross section of the ribs 17 in FIG. 2 is somewhat smaller, whereas in FIG. 2 also the additional disc plate 23 is provided.
- the outer diameter D A of the ribs is at least 2 mm and a maximum of 25 mm larger than the diameter D S of the disc plate 23rd
- FIG. 3 illustrates that the center of gravity P1 of the rib faces lies above its plane of action, which is determined by the solids discharge opening 10.
- FIG. 4 1 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 with each other.
- FIG. 6 shows that the ribs may be provided with openings 22 to relieve the rib surfaces of the ribs 17 at the solids discharge of tips of the Coriolis pressure.
