Definitions

  • the invention relates to a solid bowl screw centrifuge with a rotatable about a longitudinal axis of the centrifuge drum having at least one outlet opening for discharging clarified Good from the centrifuge drum via a flowing from the outflow Good and a discharge passage for discharging the total omitted good, wherein the weir edge on the The end face of the centrifuge drum is arranged and the outlet channel extends in the flow direction behind the weir edge, the outlet channel is curved to redirect the effluent Good in a substantially tangential direction, and the outlet channel has a bottom surface which is at least partially largely flat.
  • a solid bowl screw centrifuge is particularly in post-published WO 2012 089492 A1 described.
  • Out JP 11 197547 A is a solid bowl centrifuge known in which a baffle is provided which deflects the outflowing material from the axial flow direction radially outward.
  • the baffle is open radially outward.
  • Out JP 11 179236 A is a Vollmantelzentrifuge known with wing plates, which are triggered by the outflowing good in flight
  • the invention has for its object to provide a Vollmantelschneckenzentrifuge, in which the energy recovery due to a pulse return of the outflowing Guts is provided particularly cost effective and at the same time particularly effective.
  • a solid bowl screw centrifuge with a rotatable about a longitudinal axis centrifuge drum having at least one outlet opening for discharging clarified Good from the centrifuge drum via a flowing from the outflow Good edge and an outlet channel for discharging the entire omitted good
  • said Weir edge is arranged on the end face of the centrifuge drum and the outlet channel in particular outside, in the flow direction behind the Weir edge extends, the outlet channel is curved to redirect the effluent Good in a substantially tangential direction, and the outlet channel has a bottom surface which is at least partially largely planar, wherein the substantially flat portion of the bottom surface to the tangential direction by an angle of 8 ° is tilted radially inwards to 28 °.
  • the outlet device is provided for discharging clarified Good from a centrifuge drum on the front side of the centrifuge drum and attached there an associated outlet opening partially overlapping stationary or adjustable.
  • the outlet device comprises a weir with a weir edge and an outlet channel arranged outside the weir for discharging the entire discharged material.
  • the outlet opening is flowed through by the then axially outflowing material which flows out over the weir edge aligned there in the radial direction, that is to say transversely to the longitudinal axis.
  • the weir edge is in particular curved and widely spaced from the longitudinal axis of a first radius.
  • the downstream in the flow direction outlet channel is curved to redirect the outflowing Good in the substantially tangential direction.
  • the outlet channel is designed with a bottom surface over which the material flows. This bottom surface is preferably at least partially spaced from the longitudinal axis, as the first radius is.
  • a weir is provided on the front side, which has its weir edge in the radial plane of the front side, as in conventional weirs.
  • the weir thus arranged leads to a particularly accurate control of the material level within the centrifuge drum.
  • such a weir has only a low tendency to clog and is also very inexpensive in terms of its production. It may be provided in the design of conventional weirs optionally with a particularly wear-resistant designed weir edge. Furthermore, it can be well maintained and replaced.
  • the device according to the invention can therefore Also particularly well in the replacement of existing systems are installed.
  • the bottom surface is preferably at least partially radially outward, as the weir edge.
  • This type of flow at the weir edge has proven to be particularly advantageous in terms of the controlled removal of the material and also with regard to possible blockage.
  • the outlet channel according to the invention thus achieves two effects: It allows the controlled overflow of the weir edge in a radial direction with only slight turbulence, low imbalance risk and low risk of clogging. At the same time, the outlet channel directs the effluent material in the desired direction, in order to recover a high level of energy from the effluent.
  • the bottom surface of such outlet channel is at least partially flat or largely 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 or substantially flat portion of the bottom surface is inclined to the tangential direction by an angle of 8 ° to 28 °, preferably 18 ° radially inwardly.
  • the bottom of the outlet channel according to the invention is designed so that its plane or substantially flat portion starts against the direction of rotation of the centrifuge drum from the Auslassö Maschinensmitte starting at an angle of 3.5 °.
  • the thus flat or substantially flat section begins at the outlet opening only a predefined piece behind the Auslassö Maschinensmitte.
  • the acceleration of the outgoing material achieved according to the invention thus likewise begins only further back in the outlet channel.
  • the suction obtained with the acceleration thus likewise arises comparatively far back in the outlet channel, as a result of which an overall speed-increasing increase in speed is to be found in the outlet channel. This suction effect reduces the risk of clogging and at the same time increases the kinetic energy in the tangential direction.
  • the plane or largely flat section of the bottom surface ends particularly preferably counter to the direction of rotation of the centrifuge drum from the outlet opening center of viewed at an angle of 15 ° to 30 °, preferably 21.5 °.
  • the flat or substantially flat section of this type has a particularly advantageous length, which has proved to be very effective even with different outlet diameters and drum sizes.
  • a curved section closes on the flat or largely flat section of the bottom surface, in particular a circular arc-shaped curved portion of the bottom surface.
  • a curved section can be produced inexpensively in terms of production and leads to a flow which is not radially changed over a certain angular range and thus also radially not accelerated or decelerated.
  • Such a flow has proven to be particularly advantageous over a certain portion of the circumferential direction.
  • This bottom surface leads to a largely turbulence-free overflow at the weir edge and thus to low imbalance development at the multiple, distributed over the circumference of the centrifuge drum and each overflowed by effluent Weirs.
  • the curved outlet duct according to the invention has, viewed in the longitudinal direction of the centrifuge drum, preferably a first width and a second width in the radial direction, the second width being smaller than the first width.
  • the outlet channel tapers from the outlet openings, that is to say in the flow direction, as far as the end of the outlet channel at which the outflowing material is largely released in the tangential direction. The rejuvenation brings a steady increase in the speed of the flow and thus the kinetic energy of the outflowing material with it.
  • the curved outlet duct is therefore particularly advantageous when viewed in the outlet direction and is designed to be continuously tapered with respect to its width.
  • the acceleration is then largely turbulence-free under simultaneously deliberately directed flow through the outlet openings and the subsequent outlet channels.
  • the such outlet channel is preferably designed to be open radially inward.
  • the outlet channel is thus in contrast to known solutions of the prior art in which the outflowing material through one or more tubes in tangential direction is derived.
  • the invention according to the invention radially inwardly open channel is not only cheaper to produce, but also has less overall the risk of clogging. Furthermore, such a channel can be easily cleaned during maintenance because it is more accessible.
  • the weir edge and the outlet channel of the solid bowl screw centrifuge according to the invention are preferably designed with a component or in one piece or in one piece, wherein the component is particularly advantageous from the outside on the front side of the centrifuge drum attachable and removable from there.
  • the component is then easily retrofitted depending on the purpose of the centrifuge and can also be easily changed in case of maintenance.
  • the position of the weir cate can be adjusted well. With the adjustment of the weir edge changes in an advantageous manner at the same time the location of the associated outlet channel, without the need for further complicated adjustment or alignment work.
  • Fig. 1 the end face of a centrifuge drum 10 is shown, which according to the conventional design of a solid bowl centrifuge in its interior a receives (not shown) centrifuge screw.
  • the centrifuge drum 10 is rotatable about a longitudinal axis 12 at high speed in a direction of rotation 14.
  • outlet openings 16 are arranged uniformly spaced over a circle around the longitudinal axis 12.
  • the outlet openings 16 are used for discharging or discharging clarified (not shown) Good from the centrifuge drum 10th
  • each outlet device 18 is attached to the outside of the front side of the centrifuge drum 10.
  • Each outlet device 18 is formed as a one-piece component from a weir plate 20 and an outlet channel 22.
  • the individual weir plate 20 extends in each case in the radial direction, that is transversely to the longitudinal axis 12 and is fixed by means of two screws 24 and thereby slightly fixed in position adjustable on the end face.
  • a weir edge 26 is formed, which is curved and spaced from the longitudinal axis 12 by a radius 28. The outflowing good must overflow this weir edge 26, whereby the crop level in the centrifuge drum 10 is selectively adjustable depending on the desired clarifying power.
  • the associated outlet channel 22 which has been produced in one piece with the weir plate 20 by means of a milling process, is arranged on each of the weir plates 20 on the outside.
  • the outlet channel 22 receives the entire over the weir edge 26 flowing Good and thus serves to discharge the entire discharged from the respective outlet opening 16 Good.
  • the outlet channel 22 following in the flow direction of the weir edge 26 has a substantially rectangular cross section and in this case has a bottom surface 30.
  • the bottom surface includes a curved portion 32 that extends along the weir edge 20 (ie in the circumferential direction) against the direction of rotation 14 viewed at the beginning of the outlet opening 16 begins and after an angle 34 of 3.5 ° behind the center of the outlet opening 16 ends.
  • the curved portion 32 is designed curved according to the lateral surface of a circular cylinder with the radius 28.
  • a planar section 36 of the bottom surface 30 adjoins the curved section 32.
  • This section 36 extends from the angle 34, starting at an angle 38 of 21.6 °.
  • the flat portion 36 is inclined to the tangential direction by an angle 40 of 18 ° radially inwardly.
  • the planar portion 36 is therefore spaced further from the longitudinal axis 12 than the radius 28 is.
  • the acceleration leads to an increased conversion of the centrifugal force of the outflowing Guts in a tangentially directed motion pulse. Since in particular the entire amount of material flows through the outlet channel 22, a particularly large proportion of the centrifugal force energy of the outflowing material is converted into tangential drive energy for the rotational movement of the centrifuge drum 10.
  • This acceleration effect in the outlet channel 22 is supported by a continuous taper of the outlet channel 22 in the flow direction of the Guts, ie in the tangential direction.
  • This taper is formed in that, starting from a first width 42 for the incoming material, ie viewed in the longitudinal direction, the outlet channel 22 tapers to a second width 44 for the outflowing material, ie in the tangential or radial direction ,
  • the widths 42 and 44 are defined by two side walls 46 and 48 of the outlet channel 22, which are correspondingly curved from the longitudinal direction to the tangential direction.
  • such an outlet channel 22 is designed with a radially inwardly completely open area 50.
  • This area 50 allows a free adjustment of the product level in the outlet channel 22. Since the material can thus flow freely through the outlet channel 22, no blockages can result and the product level at the associated weir edge 26 can be free depending on the product level in the centrifuge drum 10 to adjust.
  • weir plates 20 and the there radially aligned weir edges 26 not least a particularly accurate control of the product level within the centrifuge drum 10 is possible even under highly fluctuating operating conditions.
  • the crop flows After flowing over the radially directed weir edges 26, the crop flows are thus each redirected so that they due to their flow through the outlet channel 22 when leaving the outlet 16 a in the range of 8 ° to 28 °, preferably a 18 ° from the tangential radially to have inside swung motion pulse.
  • the movement impulse thus directed has proved to be particularly advantageous with regard to the energy recycling thus produced in the centrifuge drum 10.
