Definitions

  • the invention relates to a discontinuous centrifuge with a drum rotating about a drum centrifuge drum with a jacket in which the cylindrical centrifuge shell is provided with holes for the flow of a liquid formed during centrifugation, which holes have a cross-section with an elliptical shape,
  • the invention also relates to a method for producing a jacket for such a discontinuous centrifuge. Furthermore, the invention relates to a method for operating such a discontinuous centrifuge.
  • a centrifugal separator with radial openings according to the preamble of claim 1 is known from EP 0 804 291 B1 according to the DE 696 09 594 T2 known.
  • the rotor of the centrifugal separator is constructed with passages in the form of the radial openings so that in the radial passages the risk of blockages or wear is reduced and that by a special design of the cross section of the passages a reduction of the generated noise level and an influence on the Frequencies of the sound generated in the passages occurs.
  • the passage is formed so that its radially inner cross section is initially constant or slowly increases outwardly and then jumps discontinuously outwards in the middle of the passage.
  • Discontinuous centrifuges are also used in particular for the separation of sugar crystals from sugar crystal suspensions.
  • a feedstock is supplied, for example, a magma with enriched crystal suspensions, and then treated in the centrifuge drum so as to be deposited on the inner surface of a jacket of the centrifuge drum a product, for example, here a crystals, settles.
  • the syrup exits through a working sieve, which lies on the mantle.
  • Such a design also known as periodic centrifuge for throwing off fillers is already known from the DE 1 916 280 B known. Holes are provided in the centrifuge shell, through which the liquid separated from the sugar crystals during centrifugation is discharged to the outside and leaves the centrifuge drum.
  • the object of the invention is therefore to propose a discontinuous centrifuge which has a further optimization of the centrifuge shell.
  • Another object of the invention is to provide a method for producing such a centrifuge.
  • the first object is achieved in a generic discontinuous centrifuge by means of the invention in that the cross section of the holes is continuous from the inside out that the diameter (a 2 ) of the cross sections of the holes parallel to the drum axis on the inside of the shell is equal to or nearly equal to the diameter (a 1 ) of the cross sections of the holes parallel to the drum axis on the outside of the holes and in that the diameter (I 2 ) of the cross sections of the circumferential holes on the inside of the shell is smaller than the diameter (I 1 ) of the cross sections of the circumferential holes on the outside of the shell, so that the cross sections of the holes expand outwardly.
  • the object is achieved by means of the invention in that the jacket is provided before or after the rounding of the jacket plate by means of water jet cutting with openings in elliptical shape.
  • the opening area should become larger toward the outside. At the same time, a larger area is advantageous against which the liquid can "lean".
  • the diameter of the cross sections of the holes parallel to the drum axis on the inside of the shell should be equal to the diameter of the cross sections of the holes parallel to the drum axis on the outside of the holes, it is understood that these two diameters are less than 5% of each other should differ. A slight deviation, in particular a slight extension of the cross section to the outside in this dimension is still tolerable, although it should be as low as possible.
  • the expansion of the cross-sections from the inside to the outside is by one dimension in the circumferential direction of the centrifuge drum, ie at the same time in the direction of movement of a rotating drum.
  • the wall of the hole should therefore be designed differently in the different areas of the hole wall.
  • the holes are introduced by means of a water jet cut before the rounding of the sheet to form the cylindrical centrifuge shell as openings in a cladding sheet.
  • an ellipse with running parallel to the drum axis web in the middle can be realized, which divides the ellipse into two halves symmetrical to each other.
  • This has the advantage that with the web additional surface is created, which additionally accelerates the liquid and therefore the liquid leaves the drum faster.
  • the web surface is also slightly sloping outward in the direction of rotation here.
  • the inventive design of the centrifuge shell can still use another effect.
  • the cross-sectional shape of the holes in the form of an ellipse favors a centering opening surface, which then fewer holes are required in total.
  • the ellipse has a multiple of area compared to a hole having a circular cross section at the same dimension in the axis-parallel direction. For a smaller number of holes, fewer separate manufacturing steps are needed. Accordingly, for the forwarding and further processing of the fluids passing through the elliptical holes, fewer positions have to be taken into account, at which the fluids emerge on the outside of the centrifuge drum.
  • the centrifuge drum 10 has a drive spindle 11, which also forms the vertically arranged axis of the centrifuge drum 10 and provides the rotary drive for the entire centrifuge drum 10.
  • the drive spindle 11 is indicated only schematically.
  • the direction of rotation 12 is additionally marked by an arrow.
  • the centrifuge drum 10 also has a jacket 13 which is rotated by the rotary drive 11 in a rotational movement.
  • the jacket 13 is substantially cylindrical and covered on its inner wall by a not-shown working screen.
  • the sugar crystals remain on the inside of the jacket 13 in the form of a crystallizate 14 and form a kind of sugar layer there.
  • the bottom 15 is arranged substantially perpendicular to the axis of the centrifuge drum 10. However, the bottom 15 has openings 16 through which the crystals 14 can escape from the centrifuge drum 10 due to its gravity. These openings 16 are closed during the centrifuging process and are only then opened.
  • the scraper 20 has a scraper bar 21 and an element 22 arranged on the scraper bar 21, for example a paring knife 22 or a razor.
  • the paring knife 22 or the Räumpflug are pivotable relative to the raking bar about the axis formed by the raking bar 21.
  • the peeling blade 22 and the Räumpflug parallel to the axis of the centrifuge drum 10 and thus vertically. They extend over the whole or almost the entire height of the shell 13th
  • This pivotal movement causes the paring knife 22 to move into the crystals 14 and successively peels off the layers of the crystals 14 there.
  • the scraper 20 is supplemented with its clearing bar 21 by an element 22 in the form of a paring knife or Räumflugs. In the position shown, this element 22 does not reach into the crystallizate 14. This position from the FIG. 1 and the FIG. 2 is thus taken during centrifugation.
  • the jacket 13 is provided with a larger number of holes 50. These holes 50 are in proportion so small that they in the illustration in the Figures 1 and 2 do not appear separately.
  • FIG. 3 is a jacket plate shown that for the production of a shell 13 from the Figures 1 and 2 would be suitable.
  • the holes 50 are thereby introduced by means of water jet cutting in the jacket plate for the jacket 13.
  • FIG. 4 one can see a first embodiment of a hole 50 at the top in the section and at the bottom in a plan view.
  • a hole 50 at the top in the section and at the bottom in a plan view.
  • the FIG. 4 is above the jacket plate for the jacket 13 in section and below the area of the hole 50 in plan view to recognize.
  • the hole 50 has an elliptical shape and is introduced into the jacket sheet by abrasive processes perpendicular to the plane of the sheet.
  • FIG. 5 one sees a second embodiment of a hole 50 at the top in the section and at the bottom in a plan view.
  • the hole 50 is here composed of two individual regions 50a and 50b, which together form an elliptical shape with an intermediate web 51.
  • the web is advantageously already produced slightly obliquely (viewed in plan view) and although continuously sloping outwardly in the direction of rotation.
  • FIG. 6 A third embodiment of a hole 50 at the top in section and at the bottom in a plan view can be seen.
  • the hole 50 is here in turn elliptical and divided by two webs 51a and 51b, so that three partial holes 50a, 50b and 50c are formed.
  • FIG. 7 is a plan view of an embodiment of a hole 50 is shown, the first of the representation in the FIG. 4 similar.
  • the hole 50 has a total of three dimensions.
  • a first dimension runs on the circumference of the cylinder drum and is in the FIG. 7 to recognize in the leaf level from left to right.
  • a second dimension runs on the cylinder drum parallel to the drum axis and is in the sheet plane in the FIG. 7 shown from top to bottom.
  • a third dimension is perpendicular to the jacket 13 of the centrifuge drum 10 and thus is perpendicular to the sheet plane in the FIG. 7 ,
  • the jacket 13 of the centrifuge drum has a finite dimension. It has an inner side facing the drum axis and an outer side facing the environment.
  • the hole 50 now has a cross section, which is constructed elliptical in each case.
  • the elliptical cross-section thus has a usually smaller diameter, which in the illustrated embodiment is parallel to the drum axis, in the FIG. 7 So from top to bottom.
  • a 1 denotes the diameter of the elliptical cross-section on the outside of the jacket 13
  • a 2 the diameter of the elliptical cross-section on the inside of the jacket 13.
  • both diameters a 1 and a 2 are the same and also fall each other.
  • the second, in the majority of embodiments and also in the illustrated embodiment larger diameter is perpendicular to the first diameters a 1 and a 2 in the circumferential direction of the shell 13 and thus in the FIG. 7 left to right.
  • the cross section of the elliptical hole 50 located on the outside of the drum shell is denoted by I 1
  • the diameter of the elliptical cross section located on the inside of the casing 13 in this dimension is denoted by I 2 .
  • I 1 is greater than I 2 . Since the hole wall, the ellipse-like cross-sections on the outside of the jacket 13 and inside the shell 13 connects steadily, it follows that the hole wall in the FIG. 7 on the sides, which are in the illustration above or below, perpendicular to the sheet plane, while in the areas that are located to the left or right of the hole 50, obliquely to the sheet plane.
