Definitions

  • the invention relates to a solid bowl screw centrifuge for separating a medium into at least a light and a heavy phase with a rotatable drum and a rotatable therein screw, which has a screw hub with a worm spiral disposed thereon, which forms a heavy-phase conveyor track to this with the Carry out the screw from the drum out of the light phase.
  • Solid bowl centrifuges of the above type are used to separate or separate flowable media by means of centrifugal force into at least one light and one heavy phase.
  • the heavy phase deposits radially outward in the drum and the light phase floats radially inward thereon.
  • the heavy phase is discharged with the rotatable relative to the drum screw from the drum and the light phase discharged by means of about a weir or a paring disc radially inward.
  • the invention has for its object to provide a Vollmantelschneckenzentrifuge, by means of which in comparison to known centrifuges in a cost effective manner and in particular with low maintenance costs, a high oil yield can be achieved.
  • a solid bowl screw centrifuge for separating a medium into at least one light and one heavy phase with a rotatable drum and a rotatable screw having a screw hub with a spiral screw disposed thereon forming a heavy phase conveyor to take them out of the drum with the screw out of the light phase.
  • the conveyor track at least one knife-like element is arranged, which at the Schneckennabe arranged and protrudes from it so far that it dips into the medium to be separated during operation of the solid bowl screw centrifuge.
  • a knife-like element which is attached to the screw hub emerges.
  • the knife-like element is designed blade-like or plate-shaped, acts like a blade or cutting edge and cuts or cuts through in particular that barrier layer, which would otherwise prevent an increase from light phase to radially inside.
  • the blade according to the invention sets the circulating in the drum medium due to its cutting action a relatively low resistance and is therefore subject to only little wear.
  • the knife-like element albeit narrow slit cut into the release layer, then float through the then light phase.
  • the knife-like element has in particular parallel side surfaces or blade surfaces, on which viewed in the circumferential direction, the medium can slide along resistance largely free.
  • the knife surfaces of this type also advantageously extend substantially parallel to the adjacent surfaces of the screw helix.
  • the knife-like element according to the invention is therefore preferably attached to the screw hub aligned as well as the adjacent screw helix.
  • the element acts as not transverse to the flow like a paddle but extends substantially along the flow through the respective helical turn.
  • a continuous spiral screw is used.
  • the elements according to the invention have almost no conveying action but merely sever the said barrier layer. Although this also leads to a circulation of the medium itself, this circulation is relatively low due to the cutting action of the elements according to the invention. This is also an advantage of the solution according to the invention, because an excessive circulation in the medium would only worsen the previously achieved separation into light and heavy phase again.
  • a plurality of knife-like elements are preferably provided next to one another with surfaces aligned in parallel in a conveying passage or screw flight. Particularly preferably, there are three such elements side by side. It arises with the elements arranged in this way a kind of comb, which introduces cuts into the medium at short intervals. Through these cuts or slots, the light phase can then move radially inward.
  • the knife-like elements are mounted according to the invention on a base plate, which is attached to the screw hub exchangeably fixed, in particular screwed there is.
  • a base plate which is attached to the screw hub exchangeably fixed, in particular screwed there is.
  • Such base plates are also preferably mounted in four successive flights.
  • the screw of the solid bowl screw centrifuge according to the invention generally has a cylindrical region and a conical region, wherein the elements according to the invention are preferably arranged in the cylindrical region of the screw. Furthermore, the elements on the screw hub are preferably provided in an area axially outside an inlet area for introducing the medium to be centrifuged.
  • the inlet region is designed with openings in the screw hub, through which medium, which was supplied radially inward into the screw hub, can pass radially outward into the separation space between the screw hub and the drum wall.
  • the knife-like element is preferably provided with a pointing in the direction of rotation of the screw relative to the drum leading edge, which is designed sharply.
  • the front edge of this type forms a cutting edge, which cuts through the medium and the barrier layer located therein in a largely friction-free manner.
  • the knife-like element is further preferably provided with a leading edge pointing in the direction of rotation of the screw relative to the drum, which extends obliquely relative to the radial direction of the screw.
  • the thus oblique front edge leads to a pulling or pushing cut on the knife-like element according to the invention, whereby its separation behavior is further improved and in particular becomes particularly low in friction.
  • a pulling section for which the leading edge is pivoted away from the direction of rotation of the screw relative to the drum from radially inward to radially outward.
  • the pointing in the direction of rotation of the screw relative to the drum leading edge is preferably straight.
  • the cutting edge of this kind can be produced particularly inexpensively and can also be sharpened cost-effectively.
  • the knife-like element is preferably provided with a counter to the direction of rotation of the screw relative to the drum facing back edge, which is designed dull.
  • the such back edge thus forms a dull back of the knife.
  • a slot is formed through which in particular oil can rise from radially outside to radially inside.
  • the knife-like element is further preferably provided with a counter to the direction of rotation of the screw relative to the drum facing the rear edge, which extends substantially parallel to the radial direction and in the direction of rotation of the screw set back.
  • Such back edge provided a stable, wide blade for the element according to the invention and supports the preferred pulling cutting action according to the invention.
  • the opposite to the direction of rotation of the screw relative to the drum facing back edge is preferably designed straight.
  • the back edge of this type can likewise be produced in a particularly cost-effective manner.
  • the knife-like element is also advantageously provided with a pointing in the direction of rotation of the screw relative to the drum leading edge and opposite to the direction of rotation of the screw relative to the drum facing back edge, wherein the front edge and the back edge are designed radially inward to radially outwardly facing each other , It is formed in this way a V-shaped in the side view, sheet-like element which is attached to its broad side on the screw hub and thereby has a high rigidity.
  • the knife-like element is designed with a radial outer edge relative to the screw hub, which extends substantially tangentially.
  • the thus tangentially oriented outer edge is preferably offset radially inwardly, in particular because of the setback in the direction of rotation.
  • the outer edge preferably begins behind the radial direction of the screw hub and thus also supports the desired pulling cutting action.
  • the outer edge of this type also provides a lifting effect for the medium sliding along it, by means of which medium is conveyed from radially inward to radially outward.
  • the outer edge is also preferably less radially than the radially outer edge Helix itself. So it can also dive less far into the medium, as the helix.
  • the relative to the screw hub radially outer edge is preferably designed straight.
  • the outer edge of this type can also be produced very inexpensively, so that overall the element according to the invention can be manufactured from a sheet metal in a particularly cost-effective and low-grade manner.
  • the screw 12 is formed from a tubular or hollow cylindrical screw hub 14, which is surrounded on the outside by a screw helix 16.
  • the worm gear 16 extends as a wound sheet of the screw hub 14 radially outward at right angles or with a slightly deviating from the vertical angle so far protruding that it almost touches the associated (not shown) drum of the solid bowl worm centrifuge 10.
  • the screw flight 16 dips into a medium located in the associated drum and discharges this a separating heavy phase out of a radially inwardly collecting light phase out.
  • inlet openings 18 are formed in the screw hub 14, through which medium can pass radially inwards from the inside of the screw hub 14 in order to be separated there.
  • the single knife-like element 20 is (see Fig. 2 ) is designed as a blade having a straight, sharp leading edge 26, a straight, blunt back edge 28, and a straight radially outer, outer edge 30.
  • the front edge 26 is arranged counter to the direction of rotation of the worm 12 relative to the drum from radially inward to radially outward.
  • the inclination of the front edge 26 is about 30 ° and is so far that the outer edge 30 begins only behind belonging to this base plate 22 radial direction 32.
  • the outer edge 30 then extends tangentially from there over preferably 1/3 of the entire circumferential width of the blade of the knife-like element 20.
  • the back edge 28 extends parallel to the radial direction 32 and limits the outer edge 30 radially outwardly just below the radius of the helix 16.
