Definitions

  • the invention relates to a drum lid of a rotatable about a centrifuge axis drum of a solid bowl screw centrifuge, with a first drum cover portion in which there is at least one outlet opening at which a clarified medium from within the drum via a weir edge can flow outside the drum, and a second drum cover portion which is axially outwardly of the first drum lid portion and which rotatably supports the drum, and at least one third drum lid portion via which the first drum lid portion is statically connected to the second drum lid portion.
  • Solid bowl centrifuges also known as decanters, separate with a drum rotating at high speed about a centrifuge axis, continuously flowable mixtures.
  • the mixture of substances is separated within the drum in at least two phases, wherein a so-called pond, a light phase, usually a clarified medium, floating on a heavy phase, such as particles or sludge.
  • the drum is closed at one of its two axial ends with a drum lid.
  • the drum lid has several sections, which are usually designed in one piece or screwed or welded together and in pass each other.
  • a first drum cover section there is at least one outlet opening, at which the clarified medium can flow from within the drum via a weir edge to the outside of the drum.
  • This first drum cover portion is usually designed as a disc extending plate-shaped from radially inward to radially outward.
  • a second drum cover portion is located, relative to the interior of the drum, viewed in the axial direction, outside the first drum cover portion and rotatably supports the drum therefrom.
  • On or in this second drum lid section is usually a drum bearing.
  • This third drum cover section is usually designed as a thickening or a thick-walled hollow cylinder through the interior or interior of which extends an inlet pipe for the substance mixture to be clarified or a drive shaft of a worm.
  • the outlet opening is normally provided on the outside of the drum with a weir plate having a weir edge towards the outlet opening. This weir edge at the outlet port determines or regulates the ridge level or the puddle depth of the light phase within the drum.
  • the invention has for its object to provide a drum lid of a solid bowl screw centrifuge, in which it is possible to set the at least one outlet radially inward to provide a large pond depth inside the drum.
  • a drum lid of a drum of a solid bowl screw centrifuge rotatable about a centrifuge axis with a first drum cover portion in which there is at least one outlet opening at which a clarified medium can flow from within the drum via a weir edge to the outside of the drum, and with a second drum cover portion, viewed in the axial direction outside of or in front of the first Drum cover portion and the drum is designed to be rotatably supporting, and at least a third drum cover portion, via which the first drum cover portion with the second drum cover portion is statically connected, wherein the at least one third drum cover portion is radially outwardly with respect to the weir edge.
  • the at least one third drum lid section viewed in the radial direction, is located radially inward with respect to the at least one weir edge there.
  • the weir edge or weir edges is or are located so radially outside of this third drum cover portion.
  • clarified medium can be correspondingly freely discharged radially outward. This free removal is basically necessary, because yes rotates the drum at high speed and accordingly the exiting medium is subject to high centrifugal force and therefore at the outlet based on the rotating drum cover immediately thrown radially outward.
  • the invention makes use in this regard of the fact that the at least one third drum cover section does not necessarily have to extend over the entire circumference of the drum cover, but that there may remain free space outside the weir edges despite the third drum cover section radially outward through which the clarified medium then radially can flow outside.
  • the solution according to the invention with its at least one third drum cover section, creates a supporting effect between the first and the second drum cover section, without requiring space radially inward from the weir edge or the weir edges.
  • the term "radially outward viewed radially” does not mean that the third drum cover section lies on one and the same radius or radial beam on the outside of the weir edge, but only that it is located on a circular ring which lies radially further outward. so has a larger radius than a circular ring radially further inside, on which the weir edge is located.
  • the at least one outlet opening can be positioned radially inward or close to the centrifuge axis.
  • the fact that the drum cover is weakened in terms of its rigidity is compensated for by means of the at least one third drum cover section arranged radially outwardly according to the invention.
  • the at least one third drum cover section is positioned and dimensioned so that the clarified medium can emerge from the at least one outlet opening in the circumferential direction and radially outward at operating speed of the solid bowl screw centrifuge, without impinging on the at least one third drum cover section.
  • the operating speed of solid bowl centrifuges is typically between 600 and 10,000 rpm (in words: six hundred and ten thousand revolutions per minute).
  • this high operating speed causes the clarified medium from the at least one outlet opening in the circumferential direction the drum lid and is thrown particularly radially outward. Said, further development according to the invention ensures that the clarified medium thus thrown outwards is not prevented from flowing away.
  • the at least one third drum cover section viewed in the circumferential direction, is located substantially in a circular sector next to the weir edge.
  • a circular sector is a "cake slice" of a circle.
  • a plurality of weir edges are arranged in the circumferential direction, then it is advantageous if a plurality of third drum lid sections are located between the circular sectors of the respective weir edges. If the drum cover sections are located in the circumferential direction next to the weir edges, then the corresponding weir plates can be easily mounted and dismounted from the radially outside. In particular, the circular sectors of the third drum cover section or the third drum cover sections and the circular sectors of the weir edge or the weir edges can also partially overlap. The respective third drum cover section can then be made comparatively wide, and thus correspondingly stable or stiff, in particular in the circumferential direction.
  • the number of third drum lid portions is equal to the number of outlet openings.
  • a plurality of outlet openings are arranged successively and regularly, in the same direction, on the drum cover according to the invention in the circumferential direction Spaced apart.
  • a plurality of third drum cover sections are distributed over the circumference and, in particular, also arranged successively and generally regularly spaced at equal intervals.
  • a plurality of third drum cover sections may be irregularly spaced or alternately spaced, particularly to achieve noise reduction.
  • the number of outlet openings is even or odd between 2 and 10 (in words: two and ten).
  • third drum lid sections and outlet openings With the same number of third drum lid sections and outlet openings, it is possible to provide exactly one third drum lid section at each outlet opening. In this way, not only a structurally particularly stiff construction in the form of a lattice structure can be created, but it is also a respective unhindered outflow of cleared medium between the respective third drum lid sections possible.
  • the at least one third drum cover section when viewed in the axial direction, has a substantially triangular cross-section.
  • Such, in cross-section triangular shape prevents deposition of leaking medium on the respective third drum cover portion.
  • a cross-sectionally substantially triangular shape is additionally advantageous in order to avoid flowing, clarified medium on a component of the drum cover .. The clarified medium can then always easily flow radially outward.
  • this tip portion of the drum lid portion may extend in the radial direction to near the centrifuge axis.
  • Another advantage of this triangular shape of the cross section of the third drum cover portion is that between the respective third drum cover sections radially inside comparatively much space or free space exists to arrange there ever an outlet opening and to mount an associated weir plate.
  • the at least one third drum cover section viewed in the axial direction is advantageously designed in cross-section substantially polygonal, in particular hexagonal.
  • This cross-sectional polygonal shape of the third drum cover portion results in a small circumference of the third drum cover portion, for this a comparatively large cross-sectional area. It can be transferred with this cross-sectional shape, with the same outer surface, larger forces.
  • at least one side face of the third drum cover section is arranged such that it points in the direction of the centrifuge axis, ie substantially radially.
  • At least one fourth drum cover section is preferably provided, via which the first drum cover section is also statically connected to the second drum cover section.
  • the at least one fourth drum cover section is located radially in relation to the respective weir edge radially inward.
  • This fourth drum cover portion is therefore viewed in the radial direction on a circular ring between the weir edge and the centrifuge axis. It thus connects, together with the third drum cover portion, the first with the second drum cover portion.
  • the first and the second drum cover section are then connected to one another by means of the third and the fourth drum cover section on an "outer" and an "inner” circular ring.
  • the drum cover according to the invention is amplified or stiffened accordingly in this area "grid-like". This stiffening makes it possible to transfer large forces from the first to the second drum cover portion.
  • the fourth drum cover portion is formed in cross-section as a ring or as a hollow cylinder and in particular integrally with the first and the second drum cover portion.
  • the weir edge is further formed on a weir plate, which, viewed in the axial direction in front of the associated outlet opening on the first drum cover portion is appropriate.
  • a weir plate which, viewed in the axial direction in front of the associated outlet opening on the first drum cover portion is appropriate.
  • it can seal fluid-tight at the associated outlet opening.
  • the clarified medium emerging from the outlet opening is correspondingly retained by the weir plate until the desired pond depth or the defined liquid level has been reached during filling of the drum with medium to be clarified and the clarified medium flows away over the weir edge.
  • the weir edge is preferably formed on a channel groove, which is viewed in the axial direction in the direction of flow of the clarified medium after the weir edge attached to the first drum cover portion.
  • the channel channel of this kind can deflect the clarified medium emerging through the outlet opening in the circumferential direction counter to the direction of rotation of the drum.
  • the effluent of the clarified medium can be used to assist the rotary drive of the bowl of the solid bowl centrifuge. It follows from the so deflected outflow namely an energy recovery from the effluent, clarified medium. If this channel channel is set radially close to the weir edge, comparatively much energy can be recovered from the effluent, clarified medium.
  • the weir edge is further formed on an outflow surface which, viewed in the axial direction, extends from the first drum cover section to the second drum cover section.
  • the thus aligned discharge surface "connects" the first drum cover portion substantially with the second drum cover portion and thus bridges the distance between the two drum cover sections.
  • the outflow surface also serves as a deflection of the outflowing medium in the circumferential direction. In contrast to a channel channel this outflow surface has no channel wall, but uses the second drum cover portion as a radially oriented boundary surface.
  • a deflection of the outflowing medium in the circumferential direction without Trough shape possible. This is particularly advantageous with regard to a possible risk of clogging at the outflow surface.
  • Fig. 1 shows a solid bowl screw centrifuge 10 according to the prior art with a housing 12 and with a drum 14, in particular by means of a Bearing assembly 16 is rotatably mounted.
  • the drum 14 may accordingly rotate at high speed about a centrifuge axis 18 defining an axial direction 20 and a radial direction 22.
  • the drum 14 in the axial direction 20 comprises a conical drum end 24, in which, distributed over the circumference, a plurality of ejection openings 26 are located.
  • the drum 14 is formed of a circular cylindrical drum body 28 and a plate-shaped drum lid 30.
  • the drum cover 30 is divided into three drum cover sections, a first disk-shaped drum cover section 32, a second, hollow cylindrical, thin-walled drum cover section 34 and a third, hollow cylindrical, thick-walled drum cover section 36.
  • the first disk-shaped drum cover section 32 is connected to the drum body 28.
  • the second, hollow cylindrical, thin-walled drum cover portion 34 is disposed in the bearing assembly 16 and rotatably supported by the bearing assembly 16.
  • the third, also hollow cylindrical, but thick-walled drum cover portion 36 is disposed between the first and second drum cover portion 32, 34 and integrally connected at its two axial ends.
  • a weir edge 40 is arranged.
  • a screw 42 Within the drum 14 rotates, with a comparatively low differential speed, about the centrifuge axis 18, a screw 42.
  • the screw 42 has a hollow cylindrical screw hub 44 and a surrounding spiral screw 46.
  • the worm 42 is rotatably mounted on the drum cover 30 by means of a bearing arrangement 48.
  • a medium 52 to be separated or clarified is to be introduced through the drum cover 30 and the screw hub 44 by means of a feed tube 50.
  • the medium to be clarified 52 is exposed by means of the rotation of the drum around the centrifuge axis 18 of a high centrifugal force and separated in this way into several phases. It separates into a first phase or a separated medium 54 and a second phase or a clarified medium 56.
  • the deposited medium 54 settles on the inside on the circular cylindrical drum body 28 of the drum 14 and is conveyed by the screw 42 axially to the conical drum end 24 and then along this radially inwardly and through the ejection openings 26 outwardly.
  • the generally liquid, clarified medium 56 floats on this deposited medium 54 and collects as a so-called pond to the centrifuge axis 18 out.
  • the clarified medium 56 flows over the weir edges 40 and is discharged from the centrifuge axis 18, in particular in the radial direction 22 to the outside.
  • Fig. 2 is in detail IV or in Fig. 4 such a weir edge 40 is shown on a disk-shaped, radially aligned weir plate 60. Furthermore, in detail V and in Fig. 5 represents a weir edge 40 on a trough-shaped channel channel 62.
  • the Fig. 3 shows the drum cover 30 with its direction of rotation 64 and with six outlet openings 38.
  • the outlet openings 38 are circumferentially spaced apart on a ring or circle and extend axially through the drum cover 30 therethrough.
  • the fluid level 58 within the drum 14 projects outwards in the axial direction 20 up to the radial height of the weir edges 40.
  • the three outlet openings 38 on the left side and top in the Fig. 3 are covered with weir plates 60. Via these weir plates 60, the clarified medium 56 flows in three wide outflow streams 66, which are curved in the direction of rotation.
  • three channel channels 62 are arranged with respective weir edges 40. Via these channel channels 62, the clarified medium 56 flows in a circumferentially deflected manner in a comparatively narrow outflow stream 68.
  • the channel groove 62 deflects the outflowing medium 56 so in the circumferential direction.
  • the three weir plates 60 and the three channel channels 62 are screwed by means of fastening screws 70 with the drum cover 30.

  • Fig. 4 shows one of the weir plates 60 as a flat, thin plate, which covers the outlet opening 38 in the circumferential direction completely and further in the radial direction 22 partially outwardly with its width extension.
  • the weir plate 60 thus defines with its weir edge 40 the liquid level 58 of the clarified medium 56 within the drum 14.

  • the fourth drum lid portion 48 may alternatively be polygonal.
  • the fourth drum cover portion 84 thus stiffened the drum cover 30 radially quite far inside out. It also serves to ensure that effluent, clarified medium 56 can not reach inward in the radial direction 22.
  • outlet openings 38 are provided. At three of these outlet openings 38, located in Fig. 7 On the left side and at the top, weir plates 60 with associated outflow streams 66 are shown.
