Definitions

  • the invention relates to a separator drum.
  • the drum with a vertical axis of rotation generally has a drum base and a drum top or lid part, which are screwed together by means of a separate locking ring.
  • a construction is for example from the DE 35 11 422 or the DE 39 36 165 A1 known.
  • a direct insertion of the drum base in the drum shell - see for example the US 2,369,222 or the EP 0 312 233 B1 can lead to undefined running conditions, as the drum parts due to the currently common high speeds of up to 10,000 revolutions per minute in operation too much, which in turn can lead to the loss of an exact guidance of the parts to each other.
  • This also applies to the idea of a direct screw connection between a drum base and a lid. Constructions of this kind show the centrifuge of the EP 0309 478 B1 and the generic separator of US 1,356,274 ,
  • drum top also called drum lid
  • drum base which does not require a centering ring and is fully functional even at higher speeds
  • This construction has many striking advantages.
  • the design of the threaded area reliably prevents the ingress of dirt.
  • the clamping counteracts the centrifugal force-induced widening, in particular of the lower drum part, and ensures centering and guiding of the supporting drum parts relative to one another.
  • a the drum part outside engaging behind or einklammerder centering ring is made of PCT / SE / 00249 but does not disclose the idea of direct clamping combined with a screw connection.
  • the adjacent surfaces in the region of the clamping surfaces of the drum shell and the drum base are formed conical or cylindrical.
  • piston valves and / or other emptying systems can be used without difficulty despite the simplified connection between the drum base and the drum shell.
  • the drum base can be made easier because it no longer requires a support point for the drum lid. Further, based on the outer diameter of the drum, the outer diameter of the drum seal can be increased. This results in a better utilization of the drum interior.
  • Fig. 1 shows the connection region between the drum shell 1 and the drum base 2 of a separator drum 3 according to the invention with a vertical axis of rotation (not visible here).
  • the drum shell 1 and the drum base 2 are each conical and go in the region of their largest diameter each in a on the outer circumference (drum shell) or on the outer circumference and inner circumference cylindrical portion 4, 5 via.
  • the drum base 2 has an axially slightly longer cylindrical portion 5, in which a piston valve 6 is guided axially displaceably with a peripheral seal 7.
  • the spool 6 is used to release Feststoffaustragsöffhungen 8 in the drum base 2 and to close.
  • Fig. 1 shows the opened state of the solids discharge openings.
  • the piston valve 6 In the closed state of the solids discharge openings 8 (not shown here) the piston valve 6 is located with an upper annular surface 9 on a lower collar 10 of the drum shell or on a ring seal 11 in the collar 10 at.
  • the outer cylindrical and inner conical portion 4 of the drum shell 1 is dimensioned such that it engages in the cylindrical portion 5 of the drum base 2 axially.
  • an external thread or internal thread 12,13 are respectively formed, so that the drum shell 1 is screwed into the drum base 2.
  • This annular collar 14 has in the outermost region in turn at least one axially downwardly extending projection 15, which comprises an axially above the Verschraubungs Suitees projecting annular collar 16 on the drum base 2 outside.
  • the projection 15 may also be formed as a circumferential annular collar or comprise a plurality of sections or areas which are arranged circumferentially distributed on the drum shell 1 (not visible here).
  • Fig. 1 To Fig. 1 are the approach 15 and the annular collar 16 in their facing surfaces 17 a, b formed conically, which limits the penetration depth, while Fig. 2 In this area, axially extending cylindrical surfaces 18, 19 are formed.
  • Fig. 2 discloses as such means a bore 20 in the drum shell 1.
  • the tool eg a kind of handle, not shown here
  • the bore may be closed by a bolt, for example, which is then released for attaching and securing the tool.
