Definitions

  • the invention relates to a separator, the centrifuge drum of which consists of two rotationally symmetrically connected, in particular conical parts, which form a variable annular gap for the outlet of the solids in the area of their larger diameter.
  • a separator of this type is known, for example, from US Pat. No. 3,823,868.
  • the upper and lower parts of the centrifuge drum are connected to one another by a centrally arranged support column, to which the drive shaft engages in the lower region.
  • Such a support column connecting the upper and lower parts of the centrifuge drum is relatively complicated in terms of its construction in terms of fastening the upper drum parts.
  • high edge stresses occur on the upper part fastened to the central support column, which lead to an elastic deformation of the upper part.
  • this known design principle can not be applied to separators with a relatively large diameter, in particular not when to achieve a good separation efficiency and high speeds are also required.
  • Another disadvantage of this known support column is that it takes up a relatively large space and thereby considerably reduces the plate space for the media to be separated.
  • the object of the invention is to connect the rotationally symmetrical parts of the centrifuge drum to one another in a particularly simple, space-saving and cost-saving manner.
  • This object is achieved in that the centrifuge drum parts are connected to one another by bolts which are arranged distributed uniformly in the peripheral direction in the peripheral area.
  • a central connecting column between the upper and lower part of the centrifuge drum can very advantageously be omitted, since the forces occurring during operation are absorbed by the bolts, which are distributed uniformly in the peripheral area in the peripheral area. Due to their eccentric arrangement during operation of the separator, these bolts according to the invention are practically only subjected to tension and they can therefore be dimensioned relatively small in relation to their diameter, especially when using high-quality material.
  • the bolts according to the invention therefore do not lead to any appreciable reduction in the separation space in the separator compared to known separators with a central connecting column, and they can moreover also be used particularly advantageously in separators with large diameters.
  • Another advantage of these bolts according to the invention is that they are compared to the previously known connection constructions can be manufactured with significantly less material and cost, and considerably simplify the loosening and connecting of the centrifuge drum parts.
  • Separators are also known in which the upper and lower parts of the centrifuge drum are connected to one another by a ring nut. Such a construction allows only the arrangement of individual discharge slots in the area of the largest diameter. Such a separator is therefore considerably less favorable in terms of process and action technology than a separator with a discharge slot (annular gap) which is open all round.
  • the production of the relatively large ring nut is not only expensive, but also the assembly and disassembly of the centrifuge drum is difficult and can only be accomplished with special tools.
  • the bolts are arranged in the region of the resulting axial force. In this way, a particularly uniform distribution of the forces occurring during operation of the separator between the individual bolts is very advantageously achieved.
  • the centrifuge drum consists of a lower part 1 and a conical upper part 2.
  • a conical ring part 3 is connected to the upper part 2, which forms an annular gap 4 with the lower part 1 of the centrifuge drum.
  • an annular piston-like adjusting device 5 known per se, is provided in the jacket area, with the aid of which the annular gap 4 is opened or closed.
  • a drive shaft 6 acts centrally on the lower part 1 and is connected to a drive device not shown in the drawing.
  • a feed pipe 7 for the separation media with plate pack 8 attached to it is inserted centrally from above and ends at a distance above the bottom of the lower part 1.
  • the inlet pipe 7 with the plate pack 8 is detachably connected to the upper part 2 of the centrifuge drum.
  • the centrifuge drum parts namely the lower part 1, upper part 2 and ring part 3 are connected to one another by bolts 9 which are provided in their upper region with a thread 10 and a corresponding screw nut 11.
  • These bolts 9 are very advantageously evenly distributed in the peripheral area in the circumferential direction, specifically in the area of the resulting axial force which lies in the centrifugal force field between the inner radius of the separating medium and the outer radius of the centrifuge drum. In this way, a particularly uniform transmission of the tensile forces occurring during the operation of the separator to the individual bolts 9 is very advantageously effected.
  • the bolts 9 made of high-quality material can therefore have a relatively small diameter, so that there is no significant volumetric reduction in the separation space.
  • the bolts 9 can also very advantageously be firmly connected to the lower part 1 of the centrifuge drum by a press fit, which results in a considerable simplification for the assembly or disassembly of the upper part 2.
  • only the screw nuts 11 need to be unscrewed and the upper part 2 of the centrifuge drum can be pulled out with the feed pipe 7 and plate pack 8 attached to it in a simple manner and can also be reinserted from above.
  • This very simple assembly and disassembly of the upper part 2 of the centrifuge drum is achieved by the parting line 12 which extends beyond the outer edge of the plate pack 8 and lies between the upper part 2 and the ring part 3.
  • the media to be separated for example a solid / liquid mixture
  • the media to be separated are supplied in a manner known per se in the direction of the arrow 13 from above through the central feed pipe 7 into the separation space of the centrifuge drum, while the solid phase is discharged through the annular gap 4 in the direction of the arrow 14 and the liquid phase takes place in the direction of arrow 15 upwards.
  • the structural design of the separator according to the invention not only brings about a considerable simplification in terms of structural design and maintenance in comparison with known separators, but it also enables the construction of separators while maintaining the high speeds required to achieve optimum separation efficiency with a significantly larger diameter or separation volume and correspondingly higher throughput than was previously the case.
