Description

Technical Field

[0001] The invention relates to a transport fixture for a separator insert of a centrifuge according to the preamble of claim 1 . Background Art

[0002] Separators within the meaning of this document serve to separate a mobile suspension as starting product into phases of different densities in a centrifugal field.

[0003] DE 10 2017 128 027 A1 discloses a separator having a disk assembly and a disposable component made of plastic (single-use technology - prequalified plastic parts for single use). Such a separator including a disposable component is particularly suitable for use in biotechnology or pharmacy. In the separator, the support device is designed as a magnetic support and one of the magnetic support devices is preferably also used as a drive device for rotating a cylinder, which is kept in suspension during operation. As a result, mechanical components for rotating and supporting the cylinder are eliminated, which is advantageous for the separator to be designed with a separator insert for single use, because the replacement of the separator insert can be handled very simply.

[0004] An improvement of the separator is known from DE 10 2020 121 419 A1. A separator having a frame and a separator insert arranged replaceably on the frame is disclosed, wherein the separator insert is designed to separate a flowable suspension in a centrifugal field into at least two flowable phases of different densities and to form a preassembled replaceable unit for installation in a stator unit on the frame of the separator.

[0005] The separator insert of DE 10 2020 121 419 A1 has a stationary housing and, on the other hand, a rotor that is magnetically / suspendedly supported during operation. During operation, the rotor is held in suspension by the magnetic support of the frame. Outside of operation, when the magnetic support is not activated (i.e., for example, during transport or assembly to a frame provided for this purpose), an undefined state in the housing results for the rotor, since the rotor is neither axially nor radially fixed without additional transport securing devices. This may lead to damage to the cartridge and its inserts (e.g., disk packs and distributors) or also to the housing and its inserts (e.g., inlet and outlet pipes) during transport.

[0006] It is known from DE 10 2015 108 272 A1 to use a mechanical transport fixture to avoid similar problems. For example, an internal spring is used as a transport fixture, but the spring is in the product flow, which is disadvantageous. In addition, a combination of an internal groove and a geometrically corresponding protrusion is disclosed as another possible transport fixture. The disadvantage here is that the inner cylinder must be rotated in order to guide the groove and the protrusion into each other. In the separator insert according to DE 10 2020 121 419 A1, this is impossible. In addition, an external tensioning ring is described as a transport fixture. In order to assemble the tensioning ring, it is necessary that the inner cylinder must be lifted axially upward, which cannot be achieved without problems in a closed separator insert. Another disadvantage is caused by the deformation of the components forming the housing due to the tensioning ring. Summary of the invention

[0007] The object of the present invention is to eliminate these problems and to provide a structurally simple and yet effective transport fixture for a separator insert of the generic type, in particular of the type according to DE 10 20 20 121 419 A1.

[0008] The present invention achieves this object through the technical solution of claim 1. According to claim 1, a separator insert for a separator is provided, wherein the separator insert forms a preassembled, replaceable unit, which can be installed in a frame and is designed to separate a flowable suspension into at least two flowable phases with different densities in a centrifugal field, wherein the replaceable separator insert is designed to be installed in a stator magnet on the frame of the separator and has at least the following items:

[0009] - a housing which is stationary during operation and which is designed in the manner of a container which is designed to be closed except for one or more openings;

[0010] a rotor arranged inside the housing and rotatable about an axis of rotation, having a barrel with one or more openings;

[0011] - preferably, a set of separation discs arranged in the cartridge;

[0012] at least two rotor magnets at two axially spaced-apart locations of the rotor with the barrel, by means of which the rotor with the barrel can be held in suspension and rotatably supported within the housing during operation,

[0013] - wherein the separator insert is equipped with one or more transport securing elements for transport or for assembly, the transport securing elements operating according to the principle of magnetic action,

[0014] - The cartridge, which is freely suspended during operation of the separator, is unable or substantially unable to move in the housing during transport or assembly.

[0015] In this case, the rotor and therefore also the rotor magnets are rotatable in the housing and are movable axially and / or radially to a limited extent or are not rigidly fastened in the housing.

[0016] The invention provides a simple-to-use and reliably functional transport fixture for a separator insert of a separator, which operates according to the principle of single-use technology. This advantageously makes it possible to virtually exclude damage to the cartridge and its inserts (e.g., disk packs and distributors) or also to the housing and its inserts (e.g., inlet and outlet lines) during transport or assembly of the separator insert. In addition, a hygienically impeccable transport fixture is provided.

[0017] The terms below and above refer to the preferred vertical orientation of the axis of rotation of the rotor and, if appropriate in the case of an inclined or horizontal orientation of the axis of rotation, are to be viewed in a coordinate system which is correspondingly rotated in space from the vertical orientation of the rotor and the housing.

[0018] According to a particularly preferred embodiment of the invention, the transport securing element operates according to the ferromagnetic principle, which results in a particularly simple structural embodiment of the one or more transport securing elements, which reliably fulfill their essential functions without external energy and are advantageously easy to operate and easy to assemble.

[0019] It is particularly preferably provided that the corresponding transport securing element is placed or can be placed on the housing externally so that it moves the corresponding rotor magnet and thus the entire rotor in the direction of the housing wall and preferably toward the housing wall, thereby limiting the freedom of movement of the rotor magnet and thus the corresponding rotor segment in the housing.

[0020] It is also advantageous if the one or more transport securing elements have a circular sector-shaped geometry. Thus, due to the arrangement of the one or more transport securing elements in the form of circular sectors on the outside of the housing, a defined fixed position of the rotor is easily obtained in the assembled state. In the case of a completely circular transport securing element, the fixed position of the rotor occurs randomly.

[0021] Furthermore, according to another particularly preferred embodiment variant of the invention, it is provided that the respective transport securing element can be pulled out of the housing in the radial direction or in the axial direction. This also facilitates simple handling and assembly and removal of the respective transport securing element. Removal of the respective transport securing element can be particularly simple and advantageous if the transport securing element can be pulled out of the housing in the axial direction or can be pulled out of the housing in the axial direction.

[0022] It is also advantageous if the housing has a radially extending upper first boundary wall on its upper side in the axial direction, against which one of the plurality of transport securing elements or the one transport securing element can rest, thereby achieving an easily accessible and planar and therefore advantageous mounting position for the upper first transport securing element.

[0023] According to another particularly preferred embodiment variant of the invention, an upper cylindrical first projection is connected to the first boundary wall in the axial direction, the first projection being arranged coaxially with the outer shell of the housing and having a smaller diameter than the outer shell, wherein the upper cylindrical first projection forms a cavity into which the upper rotor magnet is inserted. The upper cylindrical first projection is used to apply the one transport securing element or one of the multiple transport securing elements and forms a stop for the upper first transport securing element in the radial direction and thus enables simple and precise assembly of the transport securing element, which can thus act in a defined manner on the upper rotor magnet or the rotor.

[0024] It is also advantageous if the housing has a radially extending lower second limiting wall on its lower side in the axial direction, against which one of the plurality of transport securing elements or the one transport securing element can rest, thereby achieving an easily accessible and planar and therefore advantageous mounting position for the lower second transport securing element.

[0025] It is also advantageous if a lower cylindrical second projection is connected to the second limiting wall in the axial direction, the second projection being arranged coaxially with the outer shell of the housing and having a smaller diameter than the outer shell, wherein the lower cylindrical second projection forms a cavity into which the lower rotor magnet is inserted. The lower cylindrical second projection serves to attach the one transport securing element or one of the multiple transport securing elements and forms a stop in the radial direction for the lower second transport securing element if necessary, thereby enabling simple and precise mounting of the transport securing element, which can thus act in a defined manner on the upper rotor magnet.

[0026] Furthermore, according to another particularly preferred embodiment of the invention, it is provided that at least one upper first transport securing element is placed on an upper first limiting wall of the housing or of an upper axial limiting portion of the housing and a lower second transport securing element is placed on a lower second limiting wall of the housing. In this way, the transport securing element or elements can be placed on the housing in a simple and reliable manner.

[0027] The arrangement of the upper first transport securing element adjacent to the upper cylindrical first projection, against which it can bear externally, advantageously ensures that the upper first transport securing element can act in a defined and reliable manner on the upper rotor magnet.

[0028] According to another particularly preferred embodiment variant of the invention, it is provided that the upper first transport securing element acts on the upper rotor magnet in the radial direction so that the rotor in the region of the upper rotor magnet rests against the lateral inner wall of the upper cylindrical first projection. This achieves a fixed, defined position of the rotor during transport, which ensures safe transport in which the rotor is secured against spontaneous movements.

[0029] Alternatively, according to another particularly preferred embodiment of the invention, it can be provided that the upper first transport securing element acts on the upper rotor magnet in the radial direction and in the axial direction. This ensures advantageously reliable transport securing even for larger and heavier separator inserts. By the axial action of such an upper first transport securing element, the rotor is secured in the axial direction. By the radial action, for example, the rotor can be centered or the rotor can be radially abutted against the inner wall of the upper cylindrical first projection of the housing.

[0030] In another particularly preferred embodiment of the invention, it is provided that the first upper transport securing element has a center angle or fan angle of preferably 250° to 290°, particularly preferably 270°. This makes it possible to provide a structurally simple and therefore advantageously functionally reliable and easily assembled solid upper transport securing element.

[0031] Alternatively, according to another particularly preferred embodiment variant of the invention, it can be provided that the upper transport securing element is embodied in two or more parts and that the respective transport securing element has a center angle or sector angle between 45° and 180°. As a result, the upper transport securing element can be easily and therefore advantageously adapted to the forces required for secure transport and secure assembly and can be easily assembled and particularly easily disassembled. By means of a corresponding arrangement of two or more transport securing elements, the rotor can also be radially centered in the housing.

[0032] Furthermore, according to another particularly preferred embodiment of the invention, it is provided that the second lower transport securing element has a center angle or sector angle between 90° and 180°. As a result, the lower transport securing element can be assembled simply and therefore advantageously and disassembled particularly simply.

[0033] According to another particularly preferred embodiment variant of the invention, it is provided that the lower transport securing element acts on the lower rotor magnet in the radial direction so that the lower rotor magnet of the rotor abuts against the lateral inner wall of the lower cylindrical second projection of the housing. This achieves a fixed, defined position of the upper rotor magnet during transport, which ensures a safe transport in which the rotor is secured against spontaneous movements.

[0034] Furthermore, according to another particularly preferred embodiment of the invention, it can be provided that a buffer element with elastic properties is fastened to the respective transport securing element, thereby preventing direct contact between the respective transport securing element and the housing, thereby resulting in a particularly gentle and, if necessary, hygienically simple and reliable transport securing.

[0035] It is also conceivable to provide only one transport securing element at the top or bottom. However, the transport securing is not as optimal as if one or more transport securing elements were arranged on the housing at the top and bottom, respectively.

[0036] Further advantageous embodiments of the invention emerge from the remaining dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In the following description of the drawings, several exemplary embodiments are described. Individual features of these exemplary embodiments can also be combined with exemplary embodiments not shown and are also respectively suitable as advantageous embodiments of individual or multiple subjects of the subjects described in the main claim and the dependent claims.

[0048] exist Figure 1 , a separator insert 1 of a separator is shown, wherein the separator insert 1 each has a housing 2 and a rotor 3 which is inserted into the housing 2 and can rotate relative to the housing 2 during operation. The rotor 3 has an axis of rotation D. The axis of rotation can be oriented vertically, but it can also be oriented in another way in space. The term vertical is to be understood broadly in this context. The terms "upper" and "lower" refer to the first and second positions of the axis of rotation in a selected orientation in space, respectively.

[0049] The rotor 3 has a rotatable drum 4. During operation, the rotor 3 is held in suspension by magnetic mountings of a frame (not shown here otherwise) (see DE 10 2020 121 419 A1 for this purpose). Outside of operation, when the magnetic mountings are not activated (i.e., for example, during transport or installation in a frame provided for this purpose), an undefined state results for the rotor in the housing, since the rotor is neither axially nor radially secured without additional transport securing devices.

[0050] During operation, the rotor 2 is rotatably mounted in the machine frame at two locations which are axially spaced apart from one another in the direction of the axis of rotation by means of corresponding magnetic bearings.

[0051] For this purpose, the separator insert 1 has an upper rotor magnet 5 b and a lower rotor magnet 6 b of a magnetic support 5 , 6 , wherein the magnetic support is completed by stator magnets 5 a , 6 a of the frame (shown here without the rest of the frame).

[0052] Preferably, form-fitting means (also not shown) are provided, which can be designed as projections and recesses in order to hold the housing 2 rotationally fixed on the stator magnets 5 a , 6 a and thus on the machine frame.

[0053] The magnetic bearing devices 5 , 6 preferably act radially and axially and hold the rotatably mounted rotor 3 in suspension during operation of the separator, preferably at a distance from the housing 2 .

[0054] Such a separator with a separator insert 1 which is preferably completely or essentially made of plastic and can be easily replaced can be meaningful and advantageous when processing products in which it must be ruled out with a very high degree of safety that contaminants enter the product (the mobile suspension S or its phases LP, HP or LP1, LP2) during the centrifugal treatment, or in which cleaning and disinfection of the separator is very complex or not possible at all.

[0055] The housing 2 is preferably made of plastic or a plastic composite material. The housing 2 can be designed to be cylindrical and have a cylindrical outer shell 21 .

[0056] In an orientation where the axis of rotation D is vertical (e.g. Figure 1 As shown in FIG. 1 ), the housing 2 preferably forms a radially extending first (here upper) boundary wall 7 on its upper side in the axial direction, which is configured as an upper covering section to a certain extent here. A cylindrical first protrusion 22 (here upper) is connected to the first boundary wall 7 in the axial direction, which is arranged coaxially with the housing 21 and has a smaller diameter than the housing 21. The upper cylindrical first protrusion 22 forms a cavity 23, into which the upper rotor magnet 5 b is inserted.

[0057] The housing 2 also forms, on its underside in the axial direction, a radially extending (here lower) second delimiting wall 8 , which is formed here, in a manner of speaking, as a lower bottom.

[0058] Preferably, a (here lower) cylindrical second projection 24 is connected to the second limiting wall 8 in the axial direction, which is arranged coaxially with the housing 21 and has a smaller diameter than the housing 21. The lower cylindrical second projection 24 forms a cavity 25, into which the lower rotor magnet 6b is inserted.

[0059] The cylinder 4 is used to centrifugally separate the mobile suspension S in a centrifugal field into at least two phases LP, HP with different densities, which may be, for example, a lighter liquid phase LP or LP1 and a heavy solid phase HP or a heavy liquid phase LP2.

[0060] The barrel 4 is preferably designed at least partially cylindrical and / or conical. The housing 2 is designed in the manner of a container which is advantageously designed to be hermetically closed except for some openings / opening regions.

[0061] As shown, the cartridge 4 can have a lower cylindrical section 41 of smaller diameter, on / in which the lower rotor magnet 6 b of the lower magnetic support 6 is also formed, which transitions into a lower conical section 42, which then has a cylindrical section 43 of larger diameter, for example, and then an upper conical section 44 and then an upper cylindrical section 45 of smaller diameter, on which the rotor magnet 5 b of the upper magnetic support 5 is formed. Such a configuration of the cartridge 4 is advantageous, but not mandatory.

[0062] Inserts such as separation disc set 10 and distributor 11 are located in cartridge 4. Housing 2 has an inlet line 12 for introducing the suspended solid S to be separated or clarified into cartridge 4 and outlet lines 13, 14 for discharging phases LP, HP or LP1, LP2 produced by the centrifugal separation process.

[0063] Outside of the operation of the separator, i.e. when the magnetic supports 5, 6 are not activated, i.e., for example, during the transport or assembly of the separator insert 1, an undefined state results for the rotor 3 in the housing 2, since the rotor is neither axially nor radially fixed without additional transport securing devices. Since the corresponding rotor magnets can move axially and / or radially in the housing to a limited extent or are not rigidly fixed in the housing, this can lead to damage to the cartridge 4 and its inserts (e.g., the separation disk package 10, the distributor 11) or also to the housing 2 and its inserts (e.g., the inlet line 12 and the outlet line 13, 14) during transport.

[0064] The above-described embodiment of the separator insert shown is advantageous, but is an example and can therefore also be designed differently within the scope of the invention within the scope defined by the claims.

[0065] In order to prevent the cartridge 4, which is freely suspended during operation of the separator, from moving in the housing 2 during transport, it is provided that at least one, here in the preferred embodiment, at least one first and second transport securing element 100 are provided, which are attached externally to the housing and interact there with one of the rotor magnets 5 b or 6 b in each case in such a way that the first and second transport securing elements force the rotor magnet into a defined position in the housing 2. Preferably, the respective rotor magnet 5 b, 6 b is forced into a position in which it rests internally against the housing 2.

[0066] Preferably, for this purpose (vertical orientation with respect to the axis of rotation of the rotor during operation), a first upper transport securing element 100a and a second lower transport securing element 100b are respectively arranged in the region of the rotor magnets 5b, 6b for securing the rotor 3 to the outer contour of the housing 2, such as in Figures 2 to 9 As shown in .

[0067] In this case, the inner radius of the lower transport securing element 100 b is substantially equal to the outer radius of the cylindrical second projection 24 and the inner radius of the upper transport securing element 100 a is substantially equal to the outer radius of the cylindrical first projection 22 .

[0068] The respective transport securing elements 100 a, b operate according to the magnetic principle and are preferably ferromagnetic.

[0069] The corresponding transport fixing elements 100a, b can be constructed in the shape of a circular ring or a circular sector. Annular elements or one-piece elements with a center angle or a sector angle of >180° can only be pulled out from the housing 2 in the axial direction, which may be disadvantageous when the magnetic force is strong. Transport fixing elements 100a, b with a center angle or a sector angle of <=180° can also be pulled out from the housing 2 in the radial direction, which may be advantageous when the magnetic force is high. In the case of high magnetic force, multiple small circular sector-shaped sub-transport fixing elements 100a, b can also be used, and the sub-transport fixing elements have a corresponding small center angle or a sector angle of, for example, <90°, so as to facilitate the operability when disassembling the transport fixing elements 100a, b on the one hand, and ensure sufficient fixation of the rotor 3 for transportation on the other hand.

[0070] exist Figures 2 to 5 , a first embodiment variant of the transport securing elements 100 a, b is shown.

[0071] In order to fix the rotor 3 in the housing 2 for transportation, firstly, an upper first transport securing element 100a in the form of a circular sector with a center angle or sector angle of preferably 180° to 290°, particularly preferably 270°, is placed in the region of the rotor magnets 5b in the radial direction on the here upper first limiting wall 7 of the housing 2. Here, the upper first transport securing element 100a is arranged adjacent to the here upper cylindrical first projection 22, against which the upper first transport securing element 100a can rest externally.

[0072] The upper first transport-fixing element 100 a acts here in the radial direction on the upper rotor magnet 5 b .

[0073] The upper rotor magnet 5b of the rotor 3 is thus oriented axially centrally relative to the upper first transport securing element 100a and bears radially approximately in the region of the center of the upper first transport securing element 100a against the lateral inner wall 26 of the upper cylindrical first projection 22. The rotor 3 is thereby also fixed in a defined position (see Figure 2 and Figure 3 ), the rotor magnet 5b is fastened in the rotor.

[0074] Given a suitable choice of magnetic force, the one-piece upper transport securing element 100 a can in any case be pulled axially out of the housing again before the housing is installed in the machine frame with the stator magnets.

[0075] Preferably, immediately following the assembly of the upper transport securing element 100a, the lower rotor magnet 6b is also secured using the lower transport securing element 100b. The lower transport securing element can be designed, for example, to be "smaller" than the upper transport securing element and to be formed, for example, at a center angle or sector angle between 90° and 180°. It can be placed in the radial direction on the second limiting wall 8 of the housing 2, here at the lower part. Here, the lower second transport securing element 100b can be arranged on the housing 2 externally adjacent to the cylindrical second protrusion 24, here at the lower part, and the lower second transport securing element 100b can be externally abutted against the second protrusion.

[0076] The lower transport securing element 100 b can be brought into its position or removed from it again both axially and radially.

[0077] The lower second transport securing element 100 b therefore also acts in the radial direction on the lower rotor magnet 6 b . The lower rotor magnet 6 b of the rotor 3 therefore also rests on the lateral inner wall 27 of the lower cylindrical second projection 24 .

[0078] In order to prevent the ferromagnetic material of the respective transport securing element 100 a, b from coming into direct contact with the housing 2 , a buffer element (not shown) having elastic properties can be fastened to the respective transport securing element 100 a, b.

[0079] exist Figures 6 to 9 A second embodiment variant of the transport securing elements 100 a, b is shown in FIG.

[0080] These transport securing elements are particularly suitable for larger rotors 3 with stronger rotor magnets 5b, 6b. In order to secure the larger rotor 3 with stronger rotor magnets 5b, 6b in the housing 2 for transportation, firstly two or more first transport securing elements 100a in the form of circular sectors, here in the upper part, with a center angle or sector angle of approximately 90° to 180° are placed axially on the upper axial delimitation 29 of the upper cylindrical first projection 22 of the housing 2 (see Figure 6 and Figure 7 ).

[0081] The two or more upper first partial transport securing elements 100 a or the upper transport securing element 100 a in its entirety here acts on the upper rotor magnet 5 b , in particular in the axial direction.

[0082] The upper rotor magnet 5b of the rotor 3 is therefore first oriented axially in the direction of the two or more upper first transport securing elements 100a and radially at the location of the two or more upper transport securing elements 100a. Here, the upper rotor magnet 5b of the rotor 3 axially abuts against the inner wall 28 of the upper axial delimitation 29 of the upper cylindrical first projection 22 and is oriented radially in a central position (see Figure 6 ). As a result, the rotor 3 is also fixed axially and radially, in which the rotor magnets 5b are secured.

[0083] according to Figure 6 , regions with different inner diameters are configured on the upper transport securing element 100a, so that the upper transport securing element 100a is placed axially "on top" with a first region 1001a with a smaller inner diameter on the cylindrical first projection 22 and is placed so that it annularly surrounds the projection 22 with another region 1002a with a larger inner diameter abutting against the outer periphery of the projection. Similar features can also be configured on the lower transport securing element 100b (not shown here).

[0084] Subsequently, the lower rotor magnet 6b can also be placed together with the lower circular sector-shaped second transport securing element 100b with a center angle or sector angle between about 90° and 180° on the second limiting wall 8 of the housing 2, here at the lower part. Here, the lower second transport securing element 100b is placed adjacent to the cylindrical second projection 24 of the housing, here at the lower part, against which the lower second transport securing element 100b can rest externally.

[0085] The lower second transport securing element 100b can be placed in its position or removed from it again both axially and radially. Therefore, in the case of high magnetic forces, it may be useful to implement the upper first transport securing element 100a in multiple parts so that it can be easily pulled out axially or radially.

[0086] The lower second transport securing element 100b acts on the lower rotor magnet 6b substantially in the radial direction. The lower rotor magnet 6b of the rotor 3 is thus also attached to the inner wall 27 of the side of the lower cylindrical second protrusion 24 (see Figure 6 ).

[0087] The first and / or second transport securing element 100a, b can also be designed in a stepped manner on the outer periphery, that is, regions with different inner diameters or regions with different outer diameters are designed there. Figure 6 A radial projection 1001 b is formed on the lower transport element 100 b , which facilitates handling.

[0088] As a result, the rotor 3 , in which the rotor magnets 6 b are fastened, is also fixed radially in a defined position.

[0089] In order to prevent the respective transport securing elements 100 a , b from coming into direct contact with the housing 2 , a buffer element (not shown) having elastic properties may be fastened to the respective transport securing elements 100 a , b .
