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 e.g. known from DE 35 11 422 or DE 39 36 165 Al.
- Direct insertion of the drum base into the drum top - see, e.g. US Pat. No. 2,369,222 or EP 0 312 233 B1 can lead to undefined running conditions, since the drum parts widen too much during operation as a result of the current high speeds of up to 10,000 rpm, which in turn leads to the loss of exact guidance of the parts relative to one another can. This also applies to the idea of a direct screw connection between one
- drum top also called drum lid
- drum base which does not require a centering ring and is fully functional even at higher speeds
- the invention solves this problem by the subject matter of claim 1.
- the invention provides a separator drum for a separator with a vertical axis of rotation, with a drum top and a drum base, wherein a screw thread between the drum top and the drum base is formed, with either the drum top into the drum bottom or the drum bottom in the drum shell is screwed directly without closure ring and further wherein the respectively in the region of the screw inner drum part the outer drum part in the region of a clamping brackets outside or engages behind.
- 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 centering ring which engages or clamps the outside of the drum part is known from PCT / SE / 00249, but does not disclose the idea of a 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.
- the upper drum part is screwed into the lower drum part and has a lower projection which engages behind an upper annular collar on the lower drum part for forming the clamping, wherein preferably the drum shell outside and inside is conical and merges in its lower portion in an at least on the outer circumference cylindrical portion and further preferably wherein the drum base outside and inside is conical and merges in its upper portion in an outer and inner cylindrical portion.
- 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 a sectional view through the connecting region between the upper and the lower drum part of a first separator drum according to the invention.
- FIG. 2 shows a sectional view through the connecting region between the upper and lower drum parts of a second separator drum according to the invention.
- FIG. 1 shows the connection region between the upper drum part 1 and the lower drum part 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 preferably each conical and go in the region of its 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 serves to release solids discharge openings 8 in the drum base 2 and to close.
- the outer cylindrical and inner conical portion 4 of the drum shell 1 is dimensioned such that it a xial in the cylindrical portion 5 of the drum base 2 engages.
- 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).
- the projection 15 and the annular collar 16 in their facing surfaces 17 a, b formed conically, which limits the penetration depth, while in 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.
