Definitions
- the invention relates to a separator drum according to the preamble of claim 1 and a separator.
- separator drums In order to achieve a defined opening and closing movement, separator drums have proven successful with piston valves, which is associated with a hydraulic control system.
- the control system often includes a closing chamber from which amounts of control water are discharged for a quick opening operation of the spool valve and which is filled to close the Feststoffaustragsö réelleen again with control water.
- the opening gap which sets in particular at partial discharges, is generally smaller than the maximum opening gap. In a total emptying of the opening gap but should preferably be fully utilized, so that adhering solid can be ejected. However, this can only be achieved if the gap is large enough and remains open for a sufficient period of time.
- an additional opening chamber also called positive opening chamber
- the distributor foot has to be processed relatively expensive. If insofar different distribution variants can be realized, for example, to design the distribution channels in the distributor foot in various ways, or if openings in riser channels in one Disc set to be arranged on different radii, it is also to provide a lot of different distribution variants in a complex manner.
- the object of the invention is to simplify the structure of the generic separator drum by optimizing the structure of its distributor and, according to a preferred embodiment, also to remedy the problem described above.
- Claim 1 provides a separator drum for a separator for the centrifugal separation of a suspension into at least one liquid phase and a solid phase or into two liquid phases and preferably a solid phase, having at least the following features: a vertical axis of rotation; a drum base and a drum shell, wherein a product to be processed, through a feed pipe and a distributor in a drum interior space, said distributor having a distributor shaft, a conical distributor foot and formed in the distributor foot distribution channels in the drum interior, further comprising at least one or more Rere liquid discharge / -austräge and preferably at least one solids discharge are provided, and wherein the distributor foot consists of at least two components assembled together.
- the structural division of the distributor foot makes it easier to realize different geometries and arrangements of distribution channels in the distributor foot.
- the distributor foot has a lower distributor base and an upper, as a separate part on the distributor shaft mountable Verteilerfußabeller, because this allows the extending between these two parts distribution channels in a simple manner by providing corresponding geometric contours on the Bottom of the Verteilerfußabdecktellers and at the top of the Verteilerfußbasis be realized, these contours limit the distribution channels in the mounted state.
- conical distributor foot cover plates with one uniform Verteilerfußbasis different distribution variants to realize, especially even if a forced-opening chamber is to be provided.
- the multi-part distributor foot is advantageous in particular-but not exclusively-suitable for separator drums in which the solids discharge has Feststoffaustrags- openings in the separator drum, which are clearly visible and closable with a slidably guided in the separator drum piston valve, wherein further between the top of the spool and the Bottom of the Verteilerfußbasis an opening chamber is formed, which is acted upon for moving the piston valve with a fluid, because the very formation of such an opening chamber often makes it difficult to form suitable distribution channels in the distributor foot.
- distributor foot base and the distributor foot cover plate are of a conical design.
- a fixing of the Verteilerfußabdecktellers to the distributor shaft can be done simply by the Verteilerfußabellereller has on its inner circumference a gradation, which rests in the mounted state on a corresponding gradation of the distributor shaft.
- it is advantageous for sealing the corresponding region / gap if at least one seal, in particular a sealing ring, is arranged between the distributor foot covering plate and the distributor shaft.
- the invention makes it possible that the distribution channels are separated by ribs in the circumferential direction. It is advantageous if the distributor channels open radially into bores in the distributor shaft and / or if the distributor channels, on the other hand, extend radially up to the outer radius of the distributor foot, so that inflowing product can flow radially advantageously into the interior of the drum.
- the Verteilerfußabellereller at least one or more axial opening (s) have, which are preferably aligned upwardly with the riser channels and open down into the distribution channels. It is a particular advantage of the invention that by replacing only the Verteilerfußab- cover plate different distribution variants, for example, with openings below the riser channels at different radii, can be realized. For this purpose, ribs are preferably realized only on the underside of the distributor foot covering plate and / or on the upper side of the distributor foot base.
- the invention also provides an advantageous separator with a separator drum according to one or more of the claims directed thereon.
- FIG. 1 shows a section through a separator drum shown in simplified form with a hood, on which also an inlet region for the separator drum and a part of a drive spindle are shown;
- FIG. 2 shows a detail enlargement from FIG. 1.
- FIG. 1 shows a partially simplified representation of a separator drum which can be rotated about a vertical axis of rotation D-also called a centrifugal drum-of a separator which can be operated continuously.
- the separator drum 1 has a drum base 2 and a drum shell 3. These two drum parts are connected to each other here in not shown in detail. For example, they may be screwed together or held together by a locking ring. Although in FIG. 1 the drum top and the drum bottom part are drawn continuously in hatching, In practice, these are separate parts. Connections such as screw connections between these parts, in particular with a locking ring, are known per se to a person skilled in the art and do not require any further explanation and discussion here.
- the separator drum 1 is further formed in a preferred embodiment inside and outside double conical.
- the Separatortrommel 1 is also rotatably mounted on a drive spindle 4, so that it is rotated during operation of the rotating drive spindle 4.
- the drive spindle 4 is in a manner not shown here by a drive motor directly in extension of the drive spindle or a belt drive with a drive belt or the like. driven.
- a disk pack 5 of a plurality of plates is arranged concentrically to the vertical axis of rotation D.
- the plates of the plate package 5 have a conical shape, are stacked axially one above the other and preferably kept spaced apart from each other by means of spacers (tabs and the like) not shown here.
- a distributor 7 with a distributor shaft 6 and a distributor foot 8 is further arranged.
- the plate package 5 is held on the distributor shaft 6 - with a tubular geometry - of the distributor 7.
- the distributor shaft 6 may be provided on its outer circumference with radially outwardly projecting webs (not shown here), wherein the plates of the plate package 5 are held on these webs.
- the distributor 7 has the preferably conical distributor foot 8 which, starting from the lower region of the distributor shaft, widens conically downwardly and outwardly.
- the conical distributor foot 8 has a lower, preferably conical, distributor foot base 9, which is attached to the lower end of the distributor shaft 6 or preferably-in order to avoid gaps-is integrally formed therewith.
- the conical distributor foot 8 furthermore has a distributor foot cover plate 10 which is arranged vertically above the conical distributor foot base 9 and is axially spaced from the distributor foot base 9.
- the distributor foot covering plate 10 is mounted on the distributor shaft 6. puts.
- the Verteilerfußabdeckteller 1 0 have on its inner circumference a gradation 1 1, which is placed on a corresponding gradation 1 2 ( Figure 2) of the distributor shaft 6.
- the gradations are aligned in such a way that the distributor foot covering plate 1 0 can be placed on the distributor shaft 6 from above so that the distributor foot covering plate 1 0 rests vertically downwards on the step 1 2 of the distributor shaft 6.
- a sealing ring 1 3 may be arranged in the region of the steps 1 1 and 1 2 to the gap between see the distributor shaft 6 and the Verteilerfußabdeckteller 1 0 well seal.
- distribution channels 14 are formed between the conical Verteilerfußbasis 9 and the Verteilerfußabdeckteller 1 0 distribution channels 14 are formed. These distribution channels 14 extend conically radially outward. They open into the drum interior 1 5. In Verteilerfußab- cover plate 1 0 can also be vertically extending openings / holes 1 6 may be formed. These openings 1 6 aligned vertically upward with riser channels
- this inlet tube 1 8 preferably does not rotate with the separator drum 1 during operation of the separator drum 1, but is designed as a stationary part.
- the inlet pipe 1 8 serves to supply product to be processed in the separator drum. 1 It protrudes vertically in a preferred embodiment from above into the separator drum 1. At its lower end, the inlet pipe 1 8 opens into the distributor shaft 6, from which it is radially spaced. That through the inlet pipe
- the incoming product When entering the openings 19, the incoming product is accelerated in the circumferential direction as a result of the rotations of the separator drum 1 and is directed onto the operating rotary number brought. Then, the product passes through the distribution channels 14, the openings 16 and the riser channels 17 in gaps between the plates of the plate package 5, where the separation takes place in liquid phases of different density and / or a clarification of solids.
- the separator drum 1 of Figure 1 is exemplified as a "separator” and "clarifier", i. a liquid consisting of two different liquid phases of different density and solids is separated into these liquid phases of different density and clarified by solids. It is there in a flow channel 20 axially upwards into a (first lower) peeling chamber 21 passes, in which a mounted on the inlet pipe, not rotating in operation centripetal pump or paring disc 22 is arranged as a liquid discharge, which serves to direct the running light liquid phase upwards from the separator drum 1, to a discharge line 29 for the lighter liquid phase.
- the distributor 7 is also suitable for pure “separators” for the separation of a product in two phases “liquid / liquid” with two paring discs (or two other processes) or for pure “clarifier” with a solids discharge and only one paring disc (or another).
- the liquid discharges and solid discharges can also be designed differently than shown in the drawing.
- the heavy liquid phase flows out of the disk pack 5 into a region radially outwardly of the disk pack 5 and flows there radially outwards until it flows over the radial outer edge of a disk plate 24, which is arranged above the disk pod 5.
- the heavy liquid phase flows over the radially outer edge of the disc plate 24 up into channels 25 between the Separatortrommeloberteil 3 and the Scheideteiler 24 and is passed there into a second peeling chamber 26.
- a second peeling disk 27 is arranged as a second liquid discharge.
- the second peeling disk 27 serves to pump-like guide the heavy liquid phase through a discharge channel 28 from the separator drum 1 into the region of a discharge line 23, through which the heavy liquid phase can flow.
- a solid phase which is collected in clarifying the product to be processed in the outer radial region of the drum interior 15, is preferably a solids discharge with Feststoffaustragö réelleen 30 at the largest circumference of the separator drum. 1
- These solids discharge openings 30 can be closed by means of a piston slide 31 (FIG. 1).
- the spool 31 has a conically widening shape from the inside to the outside, wherein the first conical portion 32 widens conically vertically downward and radially outwardly. At this first conical section, a second conical section 33 connects, which is aligned in the opposite direction.
- the piston valve 31 is hydraulically actuated.
- a closing chamber 34 is formed between the lower drum part 2 and the piston slide 31. If this is supplied with fluid-preferably control water-the piston slide is moved vertically upwards, so that the piston slide 31 is closed.
- the spool 31 By pressure drop in the closing chamber 34, the spool 31, however, in particular due to the axially acting from above pressure of the product in the drum interior 1 5, however, sink vertically downwards.
- Forced opening chamber 35 (see also Fig. 2) is formed. Also, this forced opening chamber 35 can be acted upon with fluid. Before opening the Kolbenschie- bers 31 it is filled with fluid. Thereafter, the pressure in the closing chamber 34 is released. In this way, the positive opening chamber 35 can accelerate the opening movement or a particularly suitable activation of the opening movement of the piston slide 31. This makes it possible to carry out the movement of the piston slide 31 from the closed position into the open position vertically downwards in a defined time interval in a particularly defined manner.
- a second inlet channel 38 extends through the drum base 2 into the forced opening chamber 35, so that a fluid, in particular control water, can also be passed into this chamber.
- the positive opening chamber 35 is presently formed in the space between the lower conical Verteilerfußbasis 9 and the top of the spool 31. Inwardly, it is bounded by the drum base 2.
- the spool 31 and the conical distributor base 9 may have recesses and correspondingly shaped cylindrical shaped portions 44, 45. Between the spool 31 and the conical Verteilerfußbasis 9 and between the spool 31 and the drum base 3 may further seals 40, 41 may be arranged to seal the forced-opening chamber 35 in these areas / columns.
- the manifold 7 with a one-piece component comprising the parts “distributor shaft” 6 and “Verteilerfußbasis” 9 and the other mounted thereon part “Verteilerfußabeller” 1 0, which is not formed integrally with the rest of the distributor 7, It should again be mentioned that it is particularly easy to create a wide variety of distributor variants by means of this two-part design of the distributor 7.
- This relates in particular to the shape of the distributor channels 14, which are defined by corresponding contours, in particular ribs, on the upper side of the distributor foot base 9. or the underside of the distributor foot cover plate 10 can be formed.
- the distributor channels 14 can extend radially into the interior of the drum. and optionally / alternatively also by the vertically aligned openings 1 6 to be processed product in the riser channels 17 of the Tellerpaktes 5.
- the vertical openings / bores 16 in the distributor foot covering plate 10 can also be easily placed on different radii. Therefore, it is only necessary to vary the Vermaschinerabdeckteller 10 to provide manifolds 7 opening in riser channels 17 at different radii openings 1 6.
- the separator drum 1 is surrounded by a hood 42 (shown in a simplified manner).
- This hood 42 does not rotate with the separator drum 1 during operation. It has a solids trap 43 into which the solids exiting the solids discharge openings 30 flow and in which they are collected and from which they can be discharged.
