Definitions

  • the invention relates to a separator according to the preamble of claim 1.
  • Centrifugal separators for the realization of continuous operation have been known for a long time, for example in a design as nozzle separators from the JP 62 - 117649 A .
  • separators with solids discharge openings which are equipped with a hydraulically actuated piston valve, with which the solids discharge openings can be closed and opened.
  • a separator without solids discharge in the form of a separator is shown in US$2,017,734 .
  • a separator with bolted together, solid drum bottom and drum top sections is also shown in the US$2,286,354 .
  • the FR 971 978 A reveals a drum with an internal lining.
  • the outer support device stabilizes the system. Since this support device is located radially outward relative to the drum wall, which defines the drum's interior, the actual drum, which defines the spinning chamber, is hereinafter referred to as the "inner drum.”
  • the outer support device is designed as an outer drum which surrounds the inner drum completely or in sections.
  • the running behavior of the rotating system, in particular of the drum is significantly improved in a simple manner, since the outer drum stabilizes the system dynamically and mechanically.
  • Both deflections of the rotating system in the radial direction to the axis of rotation D and the tendency towards imbalance formation can be significantly reduced.
  • Both the inner drum and the support structure can - but do not have to - be designed with relatively thin walls.
  • the inner drum which is preferably replaced after processing a product batch, can thus be manufactured with very little material.
  • the outer drum can completely surround the inner drum. However, the rotating system is also well stabilized if the outer drum only axially surrounds the inner drum in sections, preferably over at least 50% of the axial length of the inner drum or more.
  • the inner drum protrudes axially from the outer drum, which makes it easier to clearly separate and space the inlet and outlet areas of the inner drum from the outer drum.
  • the weight of the outer drum can significantly exceed that of the inner drum, so that the rotational behavior is essentially determined by the outer drum.
  • the weight of the rotating parts of the metal outer drum is preferably more than twice as great, in particular more than four times as great, as the weight of the rotating plastic parts or the weight of the empty inner drum.
  • the outer drum also makes it possible to design the inner drum with particularly thin walls, as it is stabilized by the outer drum.
  • the outer drum To ensure easy and efficient insertion of the inner drum into the outer drum, it is advantageous for the outer drum to have an outer drum lower section and a detachable outer drum upper section. However, it is primarily advantageous for manufacturing reasons for the inner drum to have an inner drum lower section and an inner drum upper section that can be pre-assembled or is pre-assembled. This is because various elements, such as the clarification agent, an inlet pipe, and the like, must be placed in the inner drum during production. This is simplified by separating the upper and lower sections.
  • the outer drum top section should preferably have a central opening large enough to allow it to be inserted from above over the cover ring body, along with its supply and discharge connections and any attached hoses, which simply need to be connected after installation. This makes installation of the inner drum particularly quick and easy after removing the outer drum top section.
  • Screws and the like can also be made of plastic, but they can also be made of another material, especially if they are not touched by the product during processing.
  • the inner drum of the invention in particular, runs particularly smoothly and is therefore ideally suited as an inner drum for an outer drum.
  • a purely clamping movement of the inner drum has proven less than optimal due to effects such as slippage and the like.
  • the inner drum is thus well suited for single-use applications—especially when pretreated with radiation such as gamma radiation.
  • the outer drum 11 serves as a type of holder into which the inner drum 12 is inserted. This holder completely surrounds or encloses the inner drum 12 in the vertical or axial direction, at least in sections.
  • the outer drum 11 and the inner drum 12 are preferably connected to one another in a rotationally fixed manner. This can be achieved in particular by a positive and/or non-positive connection between the outer drum 11 and the inner drum 12.
  • connection such as a bayonet lock between the elements to be connected, the inner drum lower part 16 and the inner drum upper part 17.
  • Fig. 1c and 1d illustrate different connection variants between the elements to be connected, the inner drum lower part 16 and the inner drum upper part 17, in which these are connected to one another via a snap-in connection.
  • a lower section 20 of the inner drum lower part 16 is connected axially upwards as a separate part or as a distributor connected in one piece with the inner drum lower part and coaxially surrounding the rotation axis D, in particular distributor attachment 21 (see again Fig. 1a ), which has a complete distributor for introducing the centrifugal material into the inner drum interior or centrifugal chamber 15 and for accelerating of the centrifuged material in the circumferential direction when the drum 2 rotates.
  • the distributor attachment 21 opens at the lower end into one or more distribution channels 24, which are formed obliquely to the axis of rotation and here also open obliquely into the actual centrifugal chamber 15.
  • a drainage system with two or more drainage areas is used to drain the various product phases from drum 2.
  • a lighter liquid phase flows radially inwards and is there (see Fig. 1a and e ) is guided axially upwards in a channel 27 on the outside of the distributor attachment 21 into an annular channel 28 which is formed between the outer circumference of the inlet pipe 23 and a pipe section 29 of larger diameter which also projects from above into the inner drum upper part 17.
  • a conical plate is attached, in particular glued or molded on, which is arranged like an upper separating plate 30 above the separating plate assembly, being spaced from the drum upper part so that a gap is formed between the drum upper part and the separating plate.
  • a flange-like peripheral edge 31 is placed between the flange areas 18 and 19 of the inner drum lower part 16 and the inner drum upper part 17 and is preferably firmly glued to them, which stabilizes the arrangement of the separating plate 30 and also gives the entire construction additional strength.
  • a heavier liquid phase (or a solid phase that can still be drained off, in particular one that is still somewhat free-flowing) is guided from the region of the largest inner circumference of the drum interior through one or more bores 32 in the radially outer region of the separating plate into the gap 33 acting as a channel between the inner drum upper part 17 and the separating plate 30, preferably into a second annular channel 34 - or into one or more channels, which are preferably spaced apart by ribs - between the pipe section 29 surrounding the inlet pipe and an axial pipe extension 45 of the inner drum upper part 17.
  • the heavier and lighter liquid phases flow upwards from the annular channels 28, 34 into axially stacked annular spaces 35, 36 in a cover ring body 37, which is non-rotatably mounted (in a manner to be explained in more detail) on the housing 1. It is advantageous that this eliminates the need for nozzles or the like leading radially out of the drum for solids removal, so that there is no contact between the interior of the drum and the drum environment in the container.
  • each of the annular spaces 39, 35, 36 is preferably defined by a sealing arrangement 40, 41, 42 on one or more (here two) sealing rings arranged between the outer circumference of the inlet pipe 23 and the inner wall of the annular space.
  • the sealing arrangements 40, 41, 42 preferably comprise two axially spaced-apart sealing rings, particularly in the manner of mechanical seals.
  • the central annular space 36 is formed between the inlet pipe 23 and the inner circumference of the cover ring body 37, below the uppermost sealing arrangement 40 and above the middle sealing arrangement 41, between the outer circumference of the inlet pipe 23 and the inner circumference of the cover ring body 37.
  • This space serves to drain the light liquid phase.
  • a further connecting piece 43 can be formed on the cover ring body 37, which preferably extends radially or obliquely away from the remaining cover ring body 37.
  • the pipe end, which adjoins the separating plate 30, opens into this annular space 36 from below.
  • the central sealing arrangement 41 is arranged between the outer circumference of the pipe section 29 and the inner circumference of the cover ring body 37.
  • the annular space 35 is formed between the outer circumference of the pipe section 29 and the inner circumference of the cover ring body 37, below the middle sealing arrangement 41 and above the lower sealing arrangement 42. This lower annular space 35 serves to drain a fluid phase, which is heavier than the lighter one, from the rotating system.
  • a further connecting piece 44 can be formed on the cover ring body 37, which preferably extends (in this case obliquely) radially away from the remaining cover ring body 37.
  • the lower sealing arrangement 42 is arranged between the outer circumference of the tube extension 45 of the inner drum upper part 17 and the inner circumference of the cover ring body 37.
  • the annular body 37 widens further. It is secured by means of fastening means on its lower circumferential edge to an upper opening in the housing, through which the annular body, the tube extension 45, and the elements extending through the tube extension pass. This securing can be achieved, for example, by means of circumferentially distributed screws 22 that are screwed to the housing 1 (preferably to the cover 5).
  • the annular body 37 can have corresponding threaded screw receptacles 73 for this purpose.
  • form-locking means such as ribs 87 (and/or grooves) on the outer circumference of the inner drum and corresponding grooves 88 (and/or ribs) on the inner circumference of the outer drum 11 can be provided, which engage with each other and thus connect the two elements, inner drum 12 and outer drum 11, in a rotationally fixed manner ( Fig. 1a ).
  • the form-locking means(s), in particular ribs 87, are/are preferably formed externally on the inner conical region 16a of the inner drum lower part 16 or protrude therefrom, and the corresponding form-locking means(s), in particular grooves/recesses 88, are/are formed correspondingly on the inner conical region 13a of the inner drum upper part 13 on its inner surface. It is precisely the arrangement in/this region close to the drive spindle 7 that enables very good torque transmission from the outer drum to the inner drum, guaranteeing very smooth running. However, torque transmission in other regions externally on the inner and outer drums is also conceivable.
  • the inner drum 12 will expand radially to fit against the inner circumference of the outer drum 11, which improves the torque transmission and rotational drive of the inner drum 12 by the driven outer drum 11.
  • the housing 1 has a drain opening 59, preferably in its base 3, through which any liquid that may occur in the housing, for example, due to an unforeseen leak or that would otherwise collect there, can drain away.
  • a drain line such as a drain hose, can be arranged at a connection to the opening 59 to drain this liquid into a container.
  • the rotatable drum 2 can be connected to the drive spindle structure with a press fit (e.g., in a conical section) or by means of another torque transmission means (not shown here).
  • the motor 8 is further attached to the bottom of the housing 1 with a flange section 50 on its side facing the spindle 7, for example, screwed with screw bolts.
  • a terminal box 51 is also arranged on the motor 8.
  • FIG. 2 An upper section of the cover ring body 37 with the connecting piece 38 as a connection option for a hose-like inlet line 75 is shown, as well as an upper section of the inlet pipe and the upper sealing arrangement 40.
  • the hose-like inlet line 75 (and similarly hose-like outlet lines on the other connecting pieces 43, 44) is/are preferably pre-assembled and adhesively attached to these.
  • the hoses can be glued at the ends facing away from the connecting pieces. Before commissioning, the glued ends are cut off and welded to a piece of hose, which comes, for example, from the fermenter. Conceivable are Other options for connecting hoses and connectors and for closing any open cable ends are also possible. For example, coupling elements with a locking design are conceivable, or the ends can be closed with cable ties or similar elements.
  • the Fig. 2 to 4 also show the inlet pipe 23 in a state in which it is axially further inserted (here upwards toward the upper connection piece 38) into the body 37 (dashed line) and in a state in which it is moved slightly further axially downwards (solid line).
  • the dashed state or the further inserted state of the inlet pipe 23 indicates the transport state, and the non-dashed line indicates the installation state in the outer drum 11 for operation.
  • the axial transport lock is based on a force and/or form fit.
  • a projection 53 for example a pin, arranged on a leaf spring 52 engages in an annular groove 54 on the outer circumference of the inlet pipe 23 when it is further inserted into the cover ring body 37.
  • the force of the spring is selected such that a good transport lock is achieved, but that it is still possible to release the transport lock after transport during assembly by a targeted axial downward movement of the inlet pipe.
  • FIG. 3 Such a positive fit in an annular groove 54 of the inlet pipe 23 is achieved by a radially inwardly projecting web 55 on the cover ring body 37 engaging internally in the annular groove 54 of the inlet pipe 23.
  • a taper/bevel 56 at the free upper end of the inlet pipe 23 allows it to be inserted into the transport securing position shown in dashed lines, particularly before disposal of the rotating system or before initial transport.
  • the cover ring body 37 To release, the cover ring body 37 must be rotated so that the web 55 is aligned with a radial groove 57 above the annular groove 54. In this position, the discharge pipe can be pulled into its operating position, not shown in dashed lines (see Fig. 3b, c ).
  • FIG. 4 A releasable force connection is achieved by placing a type of clamping ring 58 (similar to a tensionable hose clamp) around the outside of the cover ring body 37 and tightening it so that it presses the cover ring body 37 force-fittingly onto the outer circumference of the further inserted supply pipe 23.
  • a type of clamping ring 58 similar to a tensionable hose clamp
  • Fig. 5 and 6 illustrate that local reinforcement elements made of plastic, in particular of the inner drum, can be provided.
  • these reinforcement elements are designed as sleeves 76, 77, 78. These sleeves are located radially between each of the sealing arrangements 40, 41, 42 and the associated inner pipe/pipe section/pipe socket 23, 29, 45 and reinforce them.
  • one or more of the sleeves can also themselves form a section of a pipe/pipe section/pipe socket 23, 29, 45.
  • a sleeve 23a forms an axial end of the inlet pipe 23.
  • the sealing arrangement 40 is arranged radially outside the sleeve 23a.
  • the sleeves 23a, 76, 77, 78 can be designed to be insulating or heat-conducting, depending on the requirements. They are preferably also made of plastic (preferably a high-temperature-resistant and preferably high-strength plastic). However, it is also conceivable and preferred to manufacture them in other ways, such as from other materials, including plastic composites or other composite materials. Reinforcing elements are conceivable, particularly those made of glass, metal, or plastic-metal compounds (e.g., plastic with metal mesh for heat dissipation). These are separated during recycling or disposal if necessary.
  • the sleeves 23a, 76, 77, 78 heat up less than the rest of the pipe/pipe section/pipe extension 23, 29, 45. This is particularly true if the sleeve 23a, 76, 77, 78 is made of metal. It is particularly advantageous if the sleeve essentially forms a pipe section of the pipe/pipe section/pipe extension 23, 29, 45.
  • the sleeve - e.g., 23a - itself forms a section, in particular an end of a pipe
  • the sleeve 23a, 76, 77, 78 and the pipe/pipe section/pipe extension 23, 29, 45 can also overlap or interlock in sections ( Fig. 7 ).
  • the sleeve is made of metal, it has a relatively high heat absorption capacity, so that it does not overheat, especially when the drum is accelerating to operating speed. This, in turn, protects temperature-sensitive components, especially the mechanical seals located in its area, which are preferably adjacent to it.
  • one or more of the sleeves 76, 77, 78 - here on the inner peripheral edge - have one or more grooves, in particular annular grooves 79, or one or more chambers, which contributes to reducing heat conduction by forming air chambers and therefore the adjacent elements, in particular Seals - protects.
