Definitions

  • the invention relates to a solid bowl screw centrifuge according to the preamble of claim 1.
  • Such solid bowl screw centrifuges have long been known in various designs, so from the DE 35 18 885 A1 , This document discloses a solid bowl screw centrifuge with a secondary clarifier, which is formed from a deposited on the screw core filter means or a lamellar jacket.
  • the suspension feed - also called distributor - opens between the clarification part - which is referred to in this document the cylindrical part of the drum - and the dehumidifying part - which is referred to in this document, the conical part of the drum, in the drum.
  • a generic solid bowl screw centrifuge according to the preamble of claim 1 is known from EP 0 461 918 B1 known.
  • circumferentially distributed planar clarification plates are arranged on the screw body according to the disclosure of this document, whose planes are parallel to the axis of rotation, but do not extend in their imaginary extension through the axis of rotation or are not radially aligned on the cylindrical screw body but on to stand diagonally.
  • This plate is partially under the liquid level during operation and acts as clarifying elements.
  • a residual screw is arranged between the outer circumference of the clarification plates and the drum inner casing, which, however, does not touch the drum casing.
  • the clarification plates optimize the clarification process.
  • a similar construction reveals the EP 0856 360 A2 ,
  • the throttle plate is provided with openings passing through it. Through the throttle plate and by a corresponding dimensioning and distribution of the openings on the throttle plate, it is possible in a simple manner to build pressure in the (Klär-) columns in the Klärplattenan Aunt because the size of the openings is smaller than for the derivation of the derived Amount of liquid necessary, which results in a targeted further optimization of the clarification.
  • FIG. 1 shows an unclaimed solid bowl screw centrifuge with a rotatable drum 1 with horizontal axis of rotation D.
  • a rotatable with a differential speed to the drum 1 screw 2 is arranged, which has a helical screw blade 3 for discharging a solid phase, over part of the axial extent of the screw body 4 is arranged on the outer circumference and rotatably coupled thereto or connected.
  • At least one liquid outlet 7 - here provided with a paring disc 8 - and a solids discharge (not shown here) at the tapered end of the drum 1 are used to discharge at least a liquid and at least one solid phase.
  • the drum 1 is at its two ends to drum bearings 9 - of which in Fig. 1 one is shown - rotatably mounted on a machine frame 10 and rotatable by means of a motor, not shown here, which is followed by a gear in rotation.
  • the worm 2 is rotatably supported by one or more worm bearings 11.
  • the screw 2 may have a differential speed to the drum 1. It can be rotated by the motor to drive the drum or via a separate motor in rotation.
  • the worm 2 preferably extends axially in the direction of the axis of rotation D via a cylindrical portion 12 of the drum and a tapering portion 13 of the drum.
  • the Klärplattenan Aunt 14 has a plurality - at least two or more, in particular more than ten - circumferentially distributed sewage plates 15 which are distributed at an angle to the radial direction to the rotation axis D outside the circumference of the screw body 4, which, for example, well in Fig. 2b can be seen.
  • the clarification plates 15 extend according to a particularly preferred embodiment parallel to the axis of rotation D of the drum 1 and the screw body 4, enforce the axis of rotation D but not in an imaginary extension / clamping their planes.
  • the clarification plates 15 are then - see Fig. 2b - Not radially perpendicular to the outer circumference of the screw body 4 but close to one side with this an acute angle ⁇ , for which applies: 0 ° ⁇ ⁇ 90 ° and preferably 45 ° ⁇ ⁇ 80 °.
  • the angle ⁇ can be dimensioned according to a repose angle of a product to be processed or a solids content of the product.
  • the Klärplattenan extract 14 may be formed as a preassembled KlärplattenMech, which is mounted as a whole on the outer circumference of the screw body 4 and is mounted.
  • the distance of the clarification plates 15 in the circumferential direction, their orientation on the screw body 4 and their radial extent are suitably determined by the expert in the context of the Kläraetgabe to be solved in the experiment.
  • the column 16 are usually sized smaller than for the processing of suspensions, in which there are larger solid particles.
  • the clarification plates 15 of the clarification plate assembly 14 preferably extend axially only over part of the cylindrical portion 13 of the drum 1 or the entire cylindrical portion 13 of the drum 1.
  • the shape of the plates 15 is largely arbitrary, but they must extend radially so far outward that they dive sufficiently far in the liquid level in operation to support the clarification can.
  • the clarification plates 15 in cross section of Fig. 1 a flat, flat shape.
  • the clarification plates 15 can also be curved in itself.
  • the sewage plates 15 also have in section the Fig. 1 , which passes through the axis of rotation D, preferably a rectangular geometry.
  • clarification plates 15 in views analogous to Fig. 1 ) have a rectangular portion 15a, and preferably towards the tapering end of the drum 1, a tapered, narrowing portion 15b (see Fig. 1 and Fig. 4 ).
  • region of section 15b can also be formed completely free of plates.
  • the clarification plates 15 are particularly preferably formed as flat sheets. For example, it is conceivable to manufacture it from a metal sheet, as it is also used for the production of separation plates of separators. However, they may also have a shape deviating from a plane shape, e.g. a slight arch shape, have.
  • the annular region is formed by the entrance of the inlet / distributor 6 into the drum without a clarifier plate.
  • the sewage plates 15 then have, for example, the type of Fig. 2a or 3a in this view a kind of L-shape on or in Fig. 1 the area 15b remains clear of the plate.
  • Fig. 2 to 3 In each case, the contour of the drum in the drawing is schematically indicated around the screw.
  • Fig. 4b shows a corresponding section through the screw 2 in the region of the manifold 6.
  • the manifold 6 is formed here as a cross manifold having four here perpendicular to each other formed inlet channels 6a, 6b, 6c, 6d, which connect the inner feed tube 5 with the drum interior.
  • the drum 1 is provided at its cylindrical end with a drum cover 18 to which a rotating with the drum peeling chamber portion 19 is attached or formed with the peeling disc 8.
  • the peeling disc 8 arranged in the peeling chamber section 19 does not rotate during operation. It serves as a liquid outlet.
  • one or more drain openings 20 are preferably formed.
  • a weir plate 21 is attached to the end of the screw 2, which rotates in operation with the screw 2 - and to this or on the Klärplattenan Aunt 14 or on a screw rotatably connected part - is mounted and which the drain holes 20 is connected upstream in the drum cover 19.
  • the weir plate 21 serves as overflow weir and extends - see Fig. 1 - Radial perpendicular to the axis of rotation - where it defines an overflow edge at its inner diameter.
  • the weir plate 21 extends radially outward as far as just before the inner circumference of the drum 1, as it is possible due to the relative movement between the drum 1 and the screw 2. Such a transfer of material in the region of the gap between the drum 1 and the outer periphery of the weir plate 21 is prevented as far as possible.
  • the extent of the weir plate 21 is radially outwardly greater than the radial extent of the clarification plates 15th
  • This weir plate 21 is replaced according to the invention by a throttle plate 22.
  • the throttle plate 22 is rotatably connected to the cylindrical end of the screw with this.
  • the throttle plate 22 preferably has such a radial extent and arrangement on the screw 2 that the clarifier plate assembly 14 is closed in the direction of the cylindrical end of the drum 1 radially over its entire circumference from the throttle plate 22 to openings 22 introduced into the throttle plate 22.
  • the throttle plate 22 extends radially outwardly as far as just before the inner periphery of the drum 1, as it due to the relative movement between the drum 1 and the screw 2 is possible. Such a transfer of material in the region of the gap between the drum 1 and the outer periphery of the throttle plate 22 is largely prevented.
  • the extension of the throttle plate 22 radially outwardly greater than the radial extent of the clarification plates 15.
  • weir plate 21 or the throttle plate 22 is alternatively attached to the drum 1 (not shown here), which the solid area outside the drum 1 to the full Seals out liquid flow, it may extend radially inward in the direction of the screw 2 only to the region of an overflow edge.
  • the weir plate 21 or the throttle plate 22 is preferably spaced as small as possible axially to the screw 2 (not shown here), for example, this axial distance is 0.5 mm to 10mm, in particular 1 to 3 mm.
  • the attachment of the throttle plate 22 or the weir plate 21 on the screw 2 is preferred because it leads to particularly advantageous results.
  • the throttle plate 22 is - as in Fig. 2 and 2b to be recognized - penetrated by a plurality of openings 23. These can have any desired shape. To Fig. 2 are the openings 23, for example, as slots and after Fig. 3 designed as elliptical holes. However, the openings 23 may also have, for example, a circular shape or an angular shape.
  • the openings 23 are distributed on the throttle plate 22, that in the assembled state, each of the gaps 16 with at least one of the openings 23 is preferably - or only partially - aligned, so that these at least one opening 23 as liquid drain from the gap 16 serves.
  • each of the column 16 is aligned with more than one of the openings 22, so that virtually in the region of the opening 23 in the axial extension directly one of the clarification plates is located.

  • the openings can also be formed by grooves / slots, which are introduced from the inner or outer periphery in the throttle plate.
  • no openings 23 are formed in the radial region of the throttle plate 22, which lies radially further outward than the maximum extent of the clarification plates 15, so that no back mixing with the product in the centrifugal space occurs here.
  • the holes 23 may all be identically formed on the throttle plate 22 or different.
  • the diameter of the openings 23 may be radially further inside smaller than further out.
  • the clarification plate body 14 with the clarification plates 15 optimizes the clarifying effect and / or - when used on a three-phase centrifuge with two liquid outlets and a solids outlet, the separating effect during the processing of a suspension to be clarified and possibly also separated into different liquid phases.
