Definitions
- the invention relates to a separator drum according to the preamble of claim 1.
- the drum with vertical axis of rotation generally has a drum base and a drum shell or lid part, which are screwed together by means of a separate closure ring.
- a construction is e.g. known from DE 35 1 1 422 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 may lead to undefined running conditions, as the drum parts are damaged due to the currently high speeds of use of e.g. up to 15000 rpm 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. Structures of this type are shown by the centrifuge of EP 0309 478 B1 and the generic separator of US Pat. No. 1,356,274.
- a centering ring which engages or clamps the outside of the drum part is known from PCT / SE / 00249.
- the generic foreign GB 1 514 073 A shows a construction in which, although the insertion of the plate package is simple, but has an extremely complicated shaped and only very expensive to produce drum base.
- the invention provides a separator drum of a continuously operable separator with a vertical axis of rotation, with a drum shell having a radially inner drum cover ring and an immediately adjoining radially outer drum cover ring, with a drum base, with a in the
- the invention is particularly suitable in connection with a closure ring-free and hinterklammerden connection between the drum base and drum top - as such a particularly advantageous in operation and against expansion of the drum base in operation simply secured secure connection of these parts is created - and preferably for a Separatortrommel with a piston valve mechanism for emptying the separator drum.
- the interior can be made particularly large.
- the Scheidetellermontage is particularly simple by the invention, at least if the divider plate is not greater than the diameter of the inner lid part.
- FIG. 1 shows a sectional view through a first embodiment of a separator according to the invention
- FIG. 2 shows a sectional view through a section of a second separator according to the invention.
- Fig. 1 shows a rotatable Separatortroinmel with a vertical axis of rotation D, which has a drum shell 1 and a drum base 2.
- the drum shell 1 is formed conically on its inner circumference and on its outer circumference.
- a plate package 4 is arranged from Trenntellern 5.
- the drum above part 1 consists of a radially inner drum cover ring 6 and a radially outer drum cover ring 7 immediately adjacent thereto, which overlap radially in their connecting region, the inner drum preferably extending in sections above the outer region of the outer drum cover ring 6 rests.
- the contact surface 8 between the inner and the outer drum lid ring 7 is aligned parallel to the horizontal or flat here according to Fig. 1, but this is not mandatory.
- the contact surface can also be formed slightly angled to the horizontal.
- a radial flange or hook projection 9 of the inner drum cover ring 6 radially engages behind a step 33 on the outer periphery of the outer drum cover ring, which stabilizes the arrangement, because during operation during rotations of the separator drum, the widening outer drum cover ring 7 lays against the flange approach.
- Fig. 1 - or alternatively - Fig, 2 - are the inner and the outer drum melmeldeckelring 6, 7 directly connected via connecting means 10, 11 directly to each other and held together.
- the connecting means 10, 11 are not connected to the drum base 2, which was considered necessary according to the prior art of EP 0023252, but this disturbs the flow paths in the separator drum and makes the construction too expensive.
- a screw-lock ring 11 is used as the connecting means, which has a radial cut 14, with which it rests on the outer peripheral portion of the inner drum cover ring 6 and an internally threaded portion 15, which on a corresponding male threaded portion 16 at a axially extending inner shoulder 32 of the outer drum cover ring 7 is screwed.
- the inner drum cover ring 6 in the connecting region between the drum cover rings 6, 7 turn axially down on the inner circumference of the outer drum cover ring 7 pressed, these rings 6 5 7 of Fig. 2 in the region of their contact surfaces 17 sections axially and partially radially abut each other , so that even this investment area is stable and dense.
- a sealing ring 3 can be arranged in the joint area.
- Both the inner drum cover ring 6 and the outer drum cover ring 7 are each at least on its inner circumference and - according to FIG. 1 - preferably also conically formed on its outer circumference, wherein the inner and possibly the outer Konizticianswinkel ⁇ , ß relative to the axis of rotation D or to a parallel to the axis of rotation D on the outer drum cover ring 6 is smaller in each case than on the inner drum cover ring 7.
- the subdivision of the cover into several parts offers insofar new optimization options in terms of drum design.
- the disk package 4 has an outer circumference smaller than the inner circumference of the outer drum cover ring 7.
- the difference in circumference may be smaller than 5 mm.
- the arrangement is particularly easy to assemble, which was problematic in the prior art, because the plate package 4 is directly accessible through the outer drum cover ring 7 therethrough.
- the outer drum cover ring 7 is provided on its outer circumference with an external thread 18 which is screwed into an internal thread 19 on the inner circumference 20 of the drum bottom part 2.
- the drum cover ring 7 rests on its outer circumference with a flange region 21 on the upper edge 22 of the drum base 2 and preferably with a hook-like, axially downwardly extending annular projection 23, wherein the 6.3fiambae 24 may optionally be formed conical.
- a piston valve 25 is arranged, which serves for opening and closing of solids discharge openings 26 (not shown here) in the lower drum 2 drum, so that the so far discontinuous also of solids emptied separator for continuous operation.
- the piston slide 25 is formed conically inwardly counter to the inner periphery of the drum shell 1.
- the spool valve 25 can be connected in a manner known per se, e.g. be hydraulically actuated, which is not shown here in detail.
- At least one or more liquid outlets - here with peeling disks 30, 31 are provided ⁇ serve to discharge at least one or more liquid phases from the drum to feed the centrifuged material.
- the inner drum cover ring 6 is integrally formed in a simple manner as Schlcro- or gripper chamber lid 34, which peeling chamber (s) 35, 36 for the paring disc (s) 30, 31 limited and possibly with one or a plurality of inner lugs 37 is provided.
- the inner drum cover ring 6 can be provided with drain holes for a respective product phase to be discharged, which extend into the peeling chamber, so that even an otherwise to be provided divider plate is replaceable.
- the peeling chamber cover 38 is designed as a separate part to the inner drum cover ring 6.
