Definitions

  • the invention relates to a separator with a rotating system with an operationally rotatable drum with a vertical axis of rotation, which has a drum interior which is divided into a lower double-conical centrifugal chamber and an upper double-conical centrifugal chamber, both centrifugal chambers each having solids discharge openings which in the lower centrifugal chamber of a piston slide and in the upper centrifugal space can be released and closed by an auxiliary slide.
  • JP S50 38858 A A similar construction is also from DE-PS 1 057 535 known.
  • the centrifugal chamber is then formed by two or more double hollow cones arranged one above the other, which makes it possible to achieve an increase in the clarification capacity with the same drum diameter.
  • This structure has proven itself in itself, but should be further developed in terms of design and functionality.
  • the state of the art is also the DE 1 141 951 A1 called.
  • This document shows a separator with a drum into which a separating plate package is inserted, the separating plate package being divided into two separating plate package sections below and above this separating plate by a separating plate which has a larger diameter than the other separating plates.
  • a product to be processed is fed through a feed in the drum shaft and enters the separation chamber via a distributor. There it in turn enters a riser channel of the separator plate package, which extends over the entire height of the separator plate package.
  • the centrifugal material entering the separation chamber is freed from the main part of the sludge in the space below the separation plate, which forms a sludge cushion on the circumference of the separation chamber.
  • the heavy liquid is prevented by the mud cushion from kicking around the outer edge of the larger diameter separating plate.
  • the remaining light liquid is separated off and collected in the upper part of the separating plate package.
  • the separated heavy liquid is discharged from the separation chamber through a channel with a larger diameter and the separated light liquid through another channel with a smaller diameter of the drum.
  • the position of the separation plate with a larger diameter can vary Application in the separation chamber can be varied. According to a preferred embodiment, it is approximately at the height of piston slide openings for discharging solid matter from the drum.
  • one separator plate section is designed as a separating device - or as a combined separating and clarifying device for separating - an incoming centrifugal material in the centrifugal field in two liquid phases and possibly for clarifying a solid phase, and the other separating plate packet section is preferred designed exclusively as a clarifying device for clarifying a liquid phase of solids.
  • the invention has the task of improving the structural design of the generic centrifuge and of expanding its area of use.
  • the auxiliary slide is also double-conical and a sealing ring is formed between the dividing plate and the auxiliary slide. In this way - and this is advantageous in order to functionally separate the centrifuge rooms sufficiently - it is prevented in a simple manner that liquid in this area flows from the lower centrifugal chamber into the upper centrifugal chamber.
  • the mass moment of inertia J Q of the rotating system about a transverse axis Q running through the center of gravity of the rotating system of the drum is greater than the mass moment of inertia J D of the rotating system about the vertical axis of rotation D of the rotating system Systems, especially more than 1, 2 times larger.
  • This configuration in each case means that the separator has a relatively large height relative to the diameter, which, in the case of a configuration of the drum interior as a double double cone, enables a high clarification performance to be achieved by separating plates with a relatively large diameter while maintaining the drum diameter.
  • the diameter of the drum is kept relatively small compared to the height, which facilitates its manufacture, among other things.
  • the interior of the drum is divided by a conical dividing plate into the lower, double-conical centrifugal space and the upper, double-conical centrifugal space.
  • the function of the interior of the drum is completely divided into two separate centrifugal spaces except for a product transfer by this dividing plate, which extends radially on the outside to the auxiliary slide and radially on the inside, preferably to the distributor, so that in a simple manner A two-stage separation in the manner of a series connection of two centrifugal separation devices can be implemented in only one rotating system.
  • the dividing plate preferably has a distribution channel for transferring clarified product from the lower centrifugal space into the upper centrifugal space. This advantageously directs the clarified product to be conveyed from the first centrifugal space into the second centrifugal space, preferably directly to the diameter of at least one riser duct in a separating plate package in the second upper centrifugal space.
  • the drum in the area of the lower centrifugal chamber can be designed as a clarifier for clarifying a flowable product of solids and in the area of the upper centrifugal chamber as a clarifier or as a combined clarifier and separator on the one hand for clarifying a flowable product from solids and for separating the product into two liquid phases of different densities (e.g. L1 and L2). Since the drum can form two centrifugal clarifiers connected in series, a particularly extensive clarification of the product is possible in only one rotating system.
  • a separating plate package is formed, each of which has one or more riser channels.
  • all of the riser channels of the lower separator plate package can lie on a different radius than all of the riser channels of the upper separator plate package in order to be able to individually adapt each of the two clarifiers to the respective clarification task.
  • the drum has a lower drum part, a middle drum part and an upper drum part or a drum cover, which are arranged vertically one above the other. This is because a relatively high drum with a diameter that is rather smaller in comparison to the height can be realized more easily than only with a drum lower part and a drum cover, which are each conical.
  • the upper drum part is conical at least in sections, that the central drum part is designed as an outer and inner cylindrical ring segment and that the lower drum part is conical at least in sections.
  • Fig. 1 shows a rotatable drum 1 of a separator with a vertical axis of rotation D. This drum forms a rotating / rotating system with all the other parts rotating during operation.
  • the drum 1 has a lower drum part 2, a middle drum part 3 and an upper drum part or a drum cover 4, which are arranged vertically one above the other.
  • the lower drum part 2 is placed on an upper end of a vertically aligned drive spindle 5 and connected to it in a rotationally fixed manner.
  • the lower drum part 2 and the drive spindle 5 are screwed together with a screw 6.
  • a drive for the drive spindle is provided below the spindle area shown, but is not shown here.
  • the central drum part 3 is designed as an essentially cylindrical ring segment which is placed on the lower drum part 2.
  • the lower drum part 2 extends radially outwards from the drive spindle 5, where it widens conically in sections downwards and merges into a cylindrical section 7 which extends axially upwards.
  • the lower drum part 2 and the middle drum part 3 are rotatably connected to one another.
  • the lower drum part 2 and the middle drum part 3 are screwed together on a thread 8, so that they overlap vertically in sections.
  • the drum middle part 3 engages behind the drum lower part 2 with an axially projecting ring collar 9, which counteracts a widening of the drum middle part 3 during operation.
  • the drum cover 4 has a radially outer ring collar 10 with which it rests on a corresponding radially inner ring collar 11 of the drum middle part 3.
  • a locking ring 12 presses the drum cover 4 against the top Drum middle part 3.
  • the locking ring 12 is screwed to a thread 13 with the drum middle part 3 or screwed into the latter.
  • a vertically aligned feed pipe 14 extends vertically into the drum 1 from above.
  • the feed pipe 14 does not rotate with the drum 1 during operation, but stands still.
  • Such stationary parts do not form part of the rotating system, which rather includes all parts of the separator rotating with the drum.
  • the non-rotating feed pipe 14 passes through a central opening of the drum cover 4 and opens vertically from above into a distributor shaft 15 of a distributor 16.
  • the distributor 16 is designed as a part that rotates with the drum 1 during operation. Therefore, the inlet pipe 14 and the distributor shaft 15 are radially spaced apart.
  • the distributor 16 opens at its lower end into a conically widening distributor section 17.
  • One or more distributor channels 18 are formed in this distributor section 17.
  • the distribution channels 18 extend obliquely to the axis of rotation radially outwards. They each have an outlet opening 19 at their outer ends. In this way, a product fed through the inlet pipe 14 into the rotating distributor shaft 15 and the distributor channels 18 is accelerated to peripheral speed in the distributor and then passed into the drum interior 20.
  • the drum interior 20 has the contour of a double double hollow cone in its radially outer region. This means that the drum interior 20 first widens conically vertically from bottom to top in a first section 20a, then tapers in a second section 20b, then tapers again in a third section 20c and then tapers again in a fourth section 20d .
  • the first and second sections 20a, b form a lower centrifugal chamber 21 and the third and fourth sections 20c, 20d form an upper centrifugal chamber 22.
  • centrifugal chambers 21, 22 are separated radially from one another by a conical graduation plate 23.
  • a separator plate package 24, 25 is formed from separator plates stacked one above the other, each of which is axially separated from one another by a gap.
  • the axial spacing of the separating plates of each plate package 24, 25 can be realized in any way per se, for example by embossed tabs (not shown here).
  • a vertically lower piston slide 26 and a vertically arranged auxiliary slide 27 are also arranged.
  • the piston slide 26 and the auxiliary slide 27 are each ring-shaped. They are each vertically limited in the drum interior 20, here displaceable, arranged.
  • the piston slide 26 has an outer conical section 26a. On its outer edge, a sealing ring 26b is formed, which seals a gap between the piston slide 26 and the lower drum part 2.
  • the auxiliary slide 27, however, is double conical. It initially tapers towards the center in a lower section 27a and then widens again in an upper section 27b.
  • the graduation plate 23 extends radially up to the auxiliary slide 27, preferably in the area of its lowest internal pressure meter.
  • a sealing ring 28 is arranged between the graduation plate 23 and the auxiliary slide 27. The sealing ring 28 is inserted here in an annular groove 29 on the outside of the graduation plate 23. In this way - and this is advantageous in order to separate the centrifugal chambers 21, 22 functionally sufficiently - it is prevented in a simple manner that liquid in this area flows from the lower centrifugal chamber 21 into the upper centrifugal chamber 22.
  • Another sealing ring 30 is formed here between the piston slide 26 and the auxiliary disk 27.
  • the sealing ring 30 is inserted here in an axially open lower annular groove 31 of the auxiliary slide 27.
  • One or more further sealing rings 32, 33 can also be provided on the outer circumference of the auxiliary slide 27 in order to also seal the gap between the drum 1 and the auxiliary slide 27.
  • the drum 1 has solids discharge openings 34, 35 at two radially spaced apart areas. These are each distributed circumferentially in the drum jacket - here, on the one hand, in the lower drum part 2 and, on the other hand, in the middle drum part 3.
  • the lower solids discharge openings 34 are in the region of the largest inner diameter of the lower centrifugal chamber 21 and the upper solids discharge openings 35 are in the region of the largest inner diameter of the upper centrifugal chamber 22.
  • the auxiliary slide 27 closes the upper solids discharge openings 35 in an upper position. In this position, it rests on the drum cover 4. In addition, the auxiliary slide 27 opens the upper solids discharge openings 35 in a lower position. In this position, he is no longer at the bottom of the drum cover 4.
  • the piston slide 26 closes the lower solids discharge openings 34 in an upper position and releases them in a lower position.
  • the outlet openings for the solid phase are only opened temporarily with a separator with a piston slide 26.
  • the piston slide 26 rests on the auxiliary slide 27 at the bottom. If it is moved into a lower position, the lower solids discharge openings 34 are exposed, so that solids are emptied from the lower centrifugal chamber 21 until the auxiliary slide 27 moves downward (inter alia because it is pressurized from above in the upper centrifugal chamber 22). , wherein it closes the lower solids discharge openings 34 and releases the upper solids discharge openings 35, so that solids are emptied from the upper centrifugal space 22.
  • Such a discharge of solids is ended first of all by the lower centrifugal chamber 21 and then the upper centrifugal chamber 22 in that the piston slide 26 is moved into its upper position again, with the auxiliary slide 27 also moves upwards, the upper solids discharge openings 35 also being closed again.
  • An actuating mechanism serves to move the internal piston slide 26. This is based on a hydraulic operating principle. To implement this, a pressure chamber 36 to which a fluid can be applied is formed below the lower piston slide 26.
  • the pressure chamber 36 can be acted upon by at least one line with a fluid, in particular a liquid such as water, which can be injected on the spindle through at least one inlet line 37 into a channel 38 in the drum 1, which opens into the pressure chamber 36.
  • a control device (not shown here) for controlling and providing the liquid is connected upstream of the feed line 37.
  • Such control devices for supplying (hydraulic) liquid into a drum 1 for moving a piston valve 26 are known per se. By injecting liquid into the pressure chamber 36, the piston slide 26 can be moved into the vertically upper position (this position is shown on the right of the axis of rotation).
  • the liquid By draining the liquid from the pressure chamber 36, for example by switching a valve 39 on the channel 38, the liquid can be drained from the pressure chamber 36, so that the spool 26 due to the pressure acting on it in the lower centrifugal chamber 21 moved to the vertically lower position (this position is shown to the left of the axis of rotation).
  • the outlet opening (s) 19 from the distributor channels lie below one or possibly a plurality of riser channels 40 in the lower separating plate package 24, which is arranged in the lower centrifugal space 21.
  • the at least one ascending channel 40 lies in the lower one Separating plate package 24 preferably radially relatively far outward, in particular in the radially outer half of the lower separating plate package 24.

  • solids flow outwards from the separating plate package 24 and collect there in the region of the largest inside diameter.
  • the clarified liquid flows radially inwards.
  • the solids collecting outside in the lower centrifugal chamber 21 are - as explained above - emptied from time to time.
  • the clarified liquid which flows radially inwards, is conducted vertically upwards in an axially extending channel 49 on the outside of the distributor shaft 16 (that is to say radially on the inside in the drum interior 20) up to the dividing plate 23, which is rotatably fitted on the outside of the distributor shaft 15 .
  • the division plate 23 is provided with one or more distribution channels 41. These distribution channels 41 are directed radially outward and conduct the clarified phase from the lower centrifugal space into the upper centrifugal space 22.
  • the distribution channels 41 have outlet openings 42. These outlet openings 42 are aligned with one or more riser channels 43 in the upper separating plate package 25, which is arranged in the upper centrifugal chamber 22.
  • the position of the riser channels 43 in the upper separator plate package 25 can be selected independently of the position of the riser channels 40 in the separator plate package 24 in the lower centrifugal chamber 21. This position depends on the liquid phases of different density to be separated (e.g. L1 and L2).
  • the clarified liquid is either drained through a single peeling disc (not shown here).
  • the upper centrifugal chamber would only be designed as a clarifier.
  • the clarified liquid is not only clarified in the upper centrifuge chamber but also separated in two phases of different densities (e.g. skimmed milk and cream). These two separate liquid phases are conducted out of the drum 1 by two liquid discharges.
  • These liquid discharges are preferably designed as peeling disks 44, 45 which are arranged vertically one above the other in peeling chambers 46, 47 within a drum cover 50 on the upper drum part 4.
  • One peeling disk 44 (here the lower one) serves to discharge the lighter liquid phase L1, which is guided radially further into one of the peeling chambers 46 and the other peeling disk 45 (here the upper one) for discharging the heavier liquid phase L2.

These parts are in Fig. 1 the parts that are not part of the rotating system. By definition, the rotating drive spindle 5 is also not added to this rotating system.
  • the centrifuged material or product to be clarified - for example milk - is passed through the central feed pipe 14, which does not rotate during operation, in the region of the distributor 16 into the rotating system.
