Definitions

  • the invention relates to a centrifuge, in particular a separator, with a drum according to the preamble of claim 1.
  • the invention has the task of optimizing the supply of the material to be processed into the disk package in the drum.
  • At least one or more tubular elements are arranged on the outer circumference of the plate package, so that in a simple manner a rising channel-like supply line of the product to be processed is carried out in the Trenntellerver, according to a possible - but not mandatory - variant distributed over the entire axial height. Furthermore, the tubular elements are attached to the outside of the separator plate package.
  • tubular elements is not too narrow.
  • it comprises a wide variety of shapes of non-circumferentially closed pipes or gutters.
  • Particularly advantageous is a semi-cylindrical groove-like shape, wherein the open side of these grooves is directed radially inward.
  • the grooves may have a semicircular cross-section but also, for example, a flattened or angled cross-section.
  • the invention also provides in development of claim 1 the claim 17, after which an optimized introduction of the product to be processed is achieved in the separation plate stack in the drum.
  • a particularly advantageous product delivery is achieved when one of the alternatives of this claim is combined with the tubular elements.
  • FIG. 1 and 3 show a portion of a lower part of a designed for continuous operation drum 1 with a vertical axis of rotation D of a trained here as a separator in a preferred embodiment centrifuge.
  • the drum 1 preferably has both a single or double conical inner shell and a single or double conical outer shell.
  • the drum 1 is here designed in several parts and has a drum lock ring 24 which holds a drum base 1a and a drum top 1b of the drum 1 together.
  • the drum 1 has a feed pipe 2, which opens into a distributor 3, which has a first tubular section 4 and an adjoining, conically widening section 5.
  • the section 5 is circumferentially distributed with here relative to the vertical axis of rotation D in the radial direction obliquely downward and outwardly extending distribution channels 6 are provided, which are formed here in a particularly preferred embodiment tubular cylindrical.
  • a plate package 7 from separating plate 8 (separating and / or clarifying acting) is arranged, between each of which a gap is formed, the height of which tabs 9 is determined.
  • the drum 1 has at least one or more liquid outlet / -lässe such as peeling discs (not shown here) and circumferentially distributed in the region of the largest diameter of the inside preferably single or double conical drum 1 solids discharge openings 10, here with the aid of a preferably fluid-operated spool 11 in the drum 1 can be opened and closed to discharge a solid phase from the drum.
  • liquid outlet / -lässe such as peeling discs (not shown here) and circumferentially distributed in the region of the largest diameter of the inside preferably single or double conical drum 1 solids discharge openings 10, here with the aid of a preferably fluid-operated spool 11 in the drum 1 can be opened and closed to discharge a solid phase from the drum.
  • the piston valve 11 is preferably hydraulically actuated, for which purpose a hydraulic system with a pilot water supply bore 21, a control valve 23, a Steuerwasserableitungsbohrung 22 and / or a control water supply 25 may be provided.
  • centrifugal material is passed through the inlet pipe 2 and the distribution channels 6 around the lower outer edge 12 of the distributor around in the plate package or the gap between the separator plates.
  • groove-like depressions are formed as deflecting regions 13 in the surface facing towards the drum interior or plate package 7 of the piston slide 11 respectively below the mouth region of each distribution channel 6, which in turn preferably radially from this area something -. a few centimeters - extend radially beyond the outer periphery of the plate package 7 and are formed in their end portion so convex that they axially parallel to the axis of rotation D outside the largest circumference of the separator plate 7 a product stream passed through the distribution channels 6 in the drum 1 turn upwards into tubular elements 14.
  • the tubular elements 14 are preferably immediately radially outwardly adjacent to the outer periphery of the separator plate package 7 and parallel to the axis of rotation of the drum first
  • the tubular elements 14 When emptying the spool is moved down, whereas the tubular elements 14 remain on the separator plate stack.
  • the tubular elements form a channel consisting of a continuous axial piece ( Fig. 1 ) or can consist of several axially juxtaposed sections ( Fig. 3 )
  • the tubular elements 14 protrude radially into the solid space 20 here.
  • the distributor 5 - see Fig. 4 - Is itself designed so that in it a deflection in the last section before its outlet opening upwards into the tubular elements 14, in which case, for example, in the manifold itself a kind of deflection 13 'may be formed in the manner of a groove-shaped depression.
  • a kind of deflection 13 ' may be formed in the manner of a groove-shaped depression.
  • the separation plates 8 are - see Fig. 2 - Separated by the radial tabs 9 and form superposed Tellerspalte.
  • the tubular elements 14 are preferably - with respect to the direction of rotation of the drum - within two tabs immediately behind the tabs. 9
  • the tubular elements 14 are preferably not formed circumferentially closed, but have radially in the drum 1 each inwardly an axially extending gap or open area (see Fig. 2 ) 15, through which the material to be processed can enter radially into the plate package 7 radially inwards.
  • the tubular elements 14 are further provided at its in the drum radially further outwardly region with axially spaced openings 16 which form a perforation-like structure in their interaction.
  • openings 16 By means of these openings 16, precipitating solids can pass from the tubular element into the solids space 20.
  • the tubular elements 14 may - but need not extend - in the vertical direction over the entire height of the separator plate package.
  • the tubular elements 14 allow a particularly uniform distribution and supply of the product to be processed in the Trenntellerbyte 7. It is therefore particularly advantageous if each of the distribution channels 6 each one of the tubular elements 14 and a deflecting channel 13 is assigned.
  • the tubular elements are fastened on the outside of the separator plate package 7, for example on one or more holding plates 19, which are each set at a predetermined axial distance between the separating plates 8 of the separating plate packet 7.
  • the tubular elements 14 can only pass through the holding plate 19 and be guided in them, for example, form-fitting manner, wherein the tubular elements are then preferably welded to at least one point, eg at the lowest holding plate.
  • This type of arrangement of the tubular elements 14 is particularly simple and easy to assemble, since the number of necessary connections between the separator plates and the tubular element is limited to a single area.
  • the holding plates 19 can each be arranged at a distance of a certain number of separation plates 8 in the plate package 7, so that they can fulfill the function of a "normal" separation plate on the one hand and are also provided with the tabs 17 and brackets.
  • the holding plate 19 may be provided at its outer periphery with annular projections / plate tabs 17, which are preferably interspersed by the tubular elements 14 positively.
  • tubular members 14 are easily held in the drum.
  • the tubular elements 14 may be formed in one piece, but also in several pieces.
  • a tube-like element from a plurality of rib-like plates or to form a tube-like element in that, for example, two rib-shaped plates are arranged in the manner of a V or L. Also, the shape of a U or semicircle is possible.
  • tubular element is formed in several pieces, then the individual elements 14a, b, c, ... are each attached to one of the retaining plates. An axial overlap of the elements 14a, b, ... would be conceivable with appropriate design.
  • An arrangement in the manner of an L basically requires that the base leg is arranged in such a way that the product emerging from the distribution channel 6 is taken along by this base limb in the circumferential direction or in the direction of rotation (FIG. Fig. 2b ).
  • the second leg closes the path radially into the solids space.
  • the tube-like elements can also protrude slightly radially inwards into the plate packs, for example if they have recesses on their outer circumference, which form a kind of groove on the outer circumference of the separator plate stack (not shown here), in which the edges of the tube-like elements 14 engage.
