Definitions

  • the invention relates to a solid bowl screw centrifuge having a centrifuge drum rotatable in operation about a longitudinal axis, at the end face at least one outflow opening for the discharge of clarified Good from the centrifuge drum, the outflow opening radially outwardly limiting weir edge and an energy recovery device for recovering energy of the outflowing, clarified goods are formed. Furthermore, the invention also relates to such an energy recovery device for attachment to a front side of a centrifuge drum.
  • the invention has for its object to provide a Vollmantelschneckenzentrifuge whose energy recovery device is particularly effective.
  • This object is inventively achieved with a solid bowl screw centrifuge with a rotatable about a longitudinal axis in operation centrifuge drum, at the end face at least one outflow opening for the discharge of clarified Good from the centrifuge drum, a discharge opening radially outwardly limiting weir edge and an energy recovery device for recovering energy of the effluent, clarified goods are formed.
  • the energy recovery device is designed as an outflow upstream of the discharge opening, flowed through by the outflowing, clarified Gut outlet pipe.
  • the object is also achieved with an energy recovery device, which is adapted for attaching directly axially outside of an associated outflow opening and designed as a flowed through by the outflowing, clarified Good Abströmrohr.
  • the outflow opening in the end face of the centrifuge drum extends essentially transversely to the longitudinal axis of the centrifuge.
  • the weir edge which can be at least slightly advantageous aligned obliquely to the longitudinal axis.
  • the energy recovery device according to the invention which is designed as a over its entire circumference substantially closed tube.
  • the pipe of this type thus forms axially outside the discharge opening a discharge line which is closed over its entire circumference.
  • This outflow tube acts with respect to the longitudinal axis radially outward like an outflow channel or a discharge channel and is at the same time closed radially in relation to the longitudinal axis.
  • the solution according to the invention is based on the recognition that the energy-recovering effect of energy recovery devices of the type mentioned is based, in particular, on the fact that this energy recovery device is closed on its radially inner side.
  • this energy recovery device is closed on its radially inner side.
  • the flowing through the energy recovery device Good is protected within this against external, aerodynamic influences.
  • the local air acts considerably on the outflowing Good, whereby this loses part of its energy content by friction with this air.
  • this energy loss is avoided, so that more energy can be recovered from the effluent.
  • the outflowing material in contrast to previously known solutions, can be deflected in a particularly homogeneous and targeted manner from the axial direction substantially in the tangential direction. At the same time energy losses, which would result from a derivative of the outflowing material in the radial direction can be avoided.
  • the discharge pipe according to the invention arranged axially outside the outflow opening, the outflowing material during the deflection is kept largely at the radius of the associated weir edge, wherein, as follows is explained, even smaller changes in the radius of the flow path can be beneficial.
  • the centrifuge drum can be advantageously configured to be rotatable in two mutually opposite directions of rotation.
  • the outflowing, clarified material is preferably deflected counter to a respective direction of rotation of the centrifuge drum with the outflow pipe.
  • the energy recovery device according to the invention can also be designed with two active surfaces as outflow tubes, of which the one active surface in a first direction of rotation and the second direction of rotation in the second direction unfolds effect.
  • the outflow tube is advantageously designed at least with a section with a substantially straight flow path which is inclined at an angle between 45 ° and 85 °, preferably between 55 ° and 65 °, of the longitudinal axis of the centrifuge drum.
  • the outflow pipe according to the invention preferably also has at least one section with a substantially straight flow path, which is inclined to the tangential direction at the outflow opening by an angle of 4 ° to 28 °, preferably 8 ° radially inwardly.
  • the bottom surface of such a section is particularly advantageous at least partially flat or largely designed flat. Such a bottom surface can be manufactured inexpensively.
  • the material flowing therefrom over a longer distance undergoes a uniform and thus comparatively easy model-technically comprehensible acceleration.
  • the acceleration leads to an increased conversion of the centrifugal force pulse into a tangentially directed motion pulse. It is converted into tangential drive energy as a particularly large proportion of the centrifugal force energy.
  • the flat portion of the bottom surface is particularly preferably inclined to the tangential direction by an angle of 4 ° to 28 °, preferably 8 ° radially inwardly.
  • Such an orientation of the deflected Gutstrahls leads in comparison to a purely tangential flow to a targeted predefined deceleration of the exiting stream and thus to a precisely predetermined accumulation effect. This jamming brings an increase in the potential energy of the flowing material and thus an improved subsequent conversion into tangential kinetic energy with it.
  • the outflow pipe according to the invention preferably has a Abstrommündung with a flow path or flow direction, which is inclined with respect to the longitudinal axis of the centrifuge drum at an angle between 70 ° and 90 °, preferably between 77 ° and 83 °.
  • the outflowing material is deflected from initially axially to substantially tangentially, ie transversely thereto.
  • a deflection to less than 90 ° with respect to the longitudinal axis has the advantage that the emerging from the Abstrommündung Good is less strongly directed against the end face of the centrifuge drum and therefore there occur less friction losses.
  • the solution according to the invention also advantageously provides a solid shell screw centrifuge, in which the outflow pipe is designed in the flow direction of the discharged, clarified material with a constant large flow cross section.
  • the outflow pipe is designed in the flow direction of the outflowing, clarified material with decreasing, in particular conically tapered, flow cross section.
  • the non-tapered flow shape reduces the risk of clogging of the discharge tube during operation of the associated solid bowl centrifuge.
  • the tapered tube shape creates an additional stowage effect resulting in improved energy recovery.
  • the outflow pipe is further designed with a round, in particular circular or elliptical cross section.
  • the discharge pipe is designed with a rectangular, in particular square cross-section.
  • the two mentioned cross-sectional shapes lead to particularly cost-recoverable energy recovery devices.
  • these cross sections are particularly suitable in order to allow the effluent to flow off in advance.
  • a right-hand cross-section has the further advantage that the outflowing material exits at the associated outlet outlet on a broad plane at a predefined radius.
  • the outflow pipe is still designed on its outer wall turned in the direction of rotation with an adapted aerodynamic outer wall shape.
  • the flow resistance of the energy recovery device and thus the associated energy loss can be reduced.
  • aerodynamically adapted outer wall form is understood to mean a shape that offers the lowest possible flow resistance for incoming air. Such a shape is rounded, has no edges and is provided with a smooth, less rough surface.
  • a solid bowl screw centrifuge 10 whose centrifuge drum 12 with its end face or end wall 14.
  • On the end wall 14 one of a plurality of axially, in the direction of a longitudinal axis 18 of the centrifuge drum 12 through the end wall 14 protruding outflow openings 16 is illustrated.
  • On the outside in front of the discharge opening 16, a weir plate 20 is stationary, but adjustably mounted on the end wall 14. The weir plate 20 protrudes up to the discharge opening 16 so that it covers the outside at its radially outer region. In this case, the weir plate 20 at its radially inwardly directed edge to a weir edge 22.
  • the weir edge 22 extends along the end wall 14 and thus transversely to the longitudinal axis 18.
  • the weir edge 22 holds in the centrifuge drum 12 clarified Good 24 back, so that in operation of the solid bowl centrifuge 10 this clarified Good 24 there with a Pond depth 26 accumulates and subsequently flows largely continuously over the weir edge 22 away.
  • an energy recovery device 28 In the flow direction of the clarified material 24 behind or downstream of the weir edge 22 is located axially on the outside of the weir plate 20, an energy recovery device 28 according to the prior art.
  • This energy recovery device 28 is designed as a discharge channel or a discharge channel 30 which has a flat bottom surface 32 that extends tangentially at the height of the weir edge 22.
  • To the bottom surface 32 extends as part of the outflow channel 30 perpendicular to a deflection surface 34, which extends arcuately according to the prior art in front of the viewed in the longitudinal direction open region of the discharge opening 16.
  • the deflecting surface 34 deflects the clarified good 24, which flows axially through the discharge opening 16 radially inwards, under the weir edge 22 in an inflow direction 38, in a tangential direction to a discharge direction 40.
  • the centrifuge drum 12 rotates in a direction of rotation 36 and the clarified Good 24 is so deflected by the deflection surface 34 that it emerges tangentially from the energy recovery device 28 against this direction of rotation 36.
  • the clarified Good 24 "pushes" from the centrifuge drum 12, whereby it transmits to this part of its pulse and contributes to an energy recovery at the centrifuge drum 12. This "repulsion" is mitigated by the internal fluid friction in the clarified Good 24 and the fact that the centrifuge drum 12 at the same time continues to rotate in the direction of rotation 36.
  • the centrifuge drum 12 thus gives way to the repulsion partially.
  • a solid bowl screw centrifuge 10 illustrated with the centrifuge drum 12, on which an energy recovery device 42 according to the invention is arranged.
  • the energy recovery device 42 also has the weir plate 20 of conventional type in front of the associated outflow opening 16.
  • On the weir plate 20 is axially outside a discharge pipe 44 which is flowed through by the exiting through the discharge opening 16, outflowing, clarified Good.
  • the outflow pipe 44 is located directly in front of the otherwise open region of the outflow opening 16 with respect to its cross section, so that it is completely covered on the outside by the outflow pipe 44. Accordingly, no air flow can act on the passage of the clarified Guts at the outlet opening 16 from the outside, resulting in a particularly uniform, in particular purely laminar flow with appropriate purity of the discharged, clarified Guts.
  • the outlet pipe 44 is located at the height or the radius of the weir edge 20, so that the material flowing through it undergoes virtually no change in position in the radial direction and accordingly no energy losses result.
  • the discharge pipe 44 is completely closed and as such forms a tubular conduit with an inlet port 46 in front of the discharge port 16 and a discharge port 48 at its other, outer end. there acts in relation to the longitudinal axis radially outer part of this tube as a discharge channel or a discharge channel and is at the same time radially inwardly closed with respect to the longitudinal axis of the centrifuge drum 12.
  • the material flowing out through the energy recovery device 42 is also protected inside the outflow pipe 44 against external, aerodynamic influences. The material is deflected homogeneously and without turbulence purposefully from the axial direction or inflow direction 38 substantially in the tangential direction or outflow direction 40.
  • the outflow pipe 44 With the outflow pipe 44, the outflowing material during the deflection is largely maintained on the radius of the weir edge 22, wherein the outflow pipe 44 in the side view ( Fig. 3 ) straight flow path 50 which is inclined to the tangential direction 52 at the discharge opening 16 by an angle 54 of 6 ° to 8 ° radially inwardly.
  • An associated bottom surface 56 of the outflow pipe 44 is flat or largely designed flat and also at an angle 54 of 6 ° to 8 ° obliquely to the tangential direction 52.
  • the outflow pipe 44 according to the Fig. 3 to 5 a rectangular flow cross-section 56, which is starting from the Einströmmündung 46 continuously tapered to Abströmmündung 48. With such a taper, the outflowing material is additionally jammed and bundled into a beam.
  • the local outflow pipe 44 is designed with an oval flow cross section 56.
  • the flow cross-section 56 of this type likewise tapers over the flow path of the outflowing material through the outflow pipe 44.
  • the outflow pipe 44 downstream of the inlet orifice 46 has a section with a longitudinal section ( Fig. 7 ) substantially straight flow path 58, which is inclined to the longitudinal axis 18 of the centrifuge drum at an angle 60 between 55 ° and 65 °.
  • this design for the outflow pipe 44 is a teardrop shape (see Fig. 6 ), which is aerodynamically particularly advantageous.
  • Fig. 9 to 11 show an embodiment of an energy recovery device 42, in which the outflow pipe 44 is designed with a substantially circular flow cross-section 56.
  • the flow path 58 which is essentially straight in longitudinal section, extends over the entire length of the outflow pipe 44, so that it is designed overall as a straight, cylindrical pipe.
  • the solution of this kind is very inexpensive to produce.
  • an embodiment of an energy recovery device 42 is illustrated, in which the associated outflow pipe 44 is designed in front of the discharge opening 16 as an inclined conical tube.
  • the tube is inclined to the longitudinal axis 18 at an angle 60 of 60 °, conically over its entire length and designed to be rectangular in the flow cross-section 56.
  • the height of the flow cross-section 56 is kept constant over the length of the outflow pipe 44.
  • the in the 15 to 17 illustrated energy recovery device 42 is designed with a kinked outflow pipe 44 having a behind a first portion at an angle 60 to the longitudinal axis 18 of 30 ° a second portion with an angle 64 to the longitudinal axis 18 of 75 °.
  • This second section forms a flow direction 62 at the associated exhaust port 48, so that the local flow path or flow direction 62 with respect to the longitudinal axis 18 of the centrifuge drum 12 is also inclined at an angle 64 of 75 °.
  • the outflowing material is deflected in principle transversely to the longitudinal axis 18, but at the same time is not deflected so strongly against the end wall 14 that energy losses occur there due to fluid friction during the outflow.
  • the local outflow pipe 44 is designed on its outer wall 66 facing in the direction of rotation 36 with an adapted aerodynamic outer wall form 68.
  • the outer wall shape 68 is such that the wall thickness, starting from the inlet port 46 decreases steadily in the flow direction of the outflowing material to Abströmmündung 48.
  • the outside of the outer wall 66 with respect to the air flowing there when rotating the centrifuge drum 12 is flatter and thus designed less in terms of the flow resistance.
  • this form of wall thickness is advantageous in view of a high rigidity of the outflow pipe 44 in relation to its weight.
  • FIGS. 18 and 19 is this shape design of a discharge pipe 44 with a continuously tapering, inner flow cross-section 56 and a continuous arc shape similar to those in Figs Fig. 3 to 5 combined.
  • the embodiment according to the FIGS. 20 and 21 also shows a continuous arc shape of the discharge pipe 44, wherein the flow cross-section 56 is kept the same size over the entire flow length. With such a flow cross-sectional profile, clogging of the outflow pipe 44 with outflowing material is additionally prevented.
