Description

[0001] The invention relates to a separation element, a spacer element and a system for a paddle separator.

[0002] Bucket separators (also known as screening buckets or sieves) are used, for example, in horticulture, landscaping, and construction to separate or sieve material mixtures according to particle size and / or consistency. They typically have several rotating shafts to which multiple separation elements are attached side-by-side along the axial direction of the shafts. The separation elements convey and turn the material to be separated, allowing finer components to fall through a gap or space between the elements, while coarser components are conveyed further within the bucket. Various designs of separation elements are known, which can be, for example, rigid or flexible buckets, plates, or lamellae.

[0003] The known solutions have the disadvantage, among others, that the separation elements are usually fixed to the respective shaft. If a different type of separation element is to be used, or if the distance or gap width between the separation elements is to be changed, the entire shaft generally has to be replaced, which is complex and expensive.

[0004] Accordingly, it is an object of the invention to provide a solution that at least partially avoids the disadvantages of previous solutions. In particular, it is an object of the invention to provide a solution that, among other things, enables simplified replacement of a separation element and / or simplified adjustment of the distance between separation elements on a shaft of a blade separator.

[0005] The problem is solved by the features of the independent claims. Advantageous further developments are specified in the dependent claims and the description.

[0006] According to a first general aspect of the invention, a separation element is provided for a blade separator having at least one rotatable shaft. The separation element can be arranged on the at least one shaft for material separation.

[0007] The separation element comprises a base body made up of several segments that are connected (preferably permanently connected) or connectable to form a shaft receptacle. The shaft receptacle is designed as an opening for the detachable fastening (of the separation element) to at least one shaft.

[0008] A paddle separator, as defined in the present invention, is a device for the mechanical separation of materials or material mixtures. The paddle separator comprises at least one rotatable shaft, and usually several shafts, on which several separation elements are (or can be) arranged axially side by side. The separation elements are designed and arranged such that they convey, turn, and loosen the supplied material during rotation, allowing smaller material fragments or parts to fall through gaps or spaces formed between the separation elements and out of the paddle separator, while larger material fragments can be conveyed further within the paddle separator. The material is typically not crushed or broken, thus enabling the material to be separated and sieved as gently as possible.

[0009] At least one shaft is located in a bucket or shovel housing of the bucket separator and is driven by a rotary motion. If the bucket separator has multiple shafts, these are usually arranged parallel to each other. The bucket separator can have a screening capacity of several tons of material per hour. The bucket separator can be designed, in particular, as an attachment for construction machinery, e.g., excavators, wheel loaders, and / or telescopic handlers.

[0010] A separation element within the meaning of the present invention is understood to be a component for material separation in and / or on a blade separator, which can be arranged or is arranged on a rotatable shaft. As previously described, the separation element is designed such that, as the shaft rotates, it conveys, turns, and loosens the fed material, allowing smaller material fragments to fall through gaps formed between the separation elements. The separation element can have different geometries and / or material designs to adapt it to various operating conditions and for separating different types of materials.

[0011] The present disclosure thus provides a simple solution for attaching or replacing the separation element on the shaft of a blade separator. The detachable mounting of the separation element on the shaft allows for quick and easy replacement of individual separation elements without requiring disassembly or replacement of the entire blade separator shaft. Furthermore, it offers the possibility of mounting the separation element at various positions along the respective shafts, thereby flexibly adjusting the spacing between adjacent separation elements to accommodate different material properties and separation requirements. This spacing corresponds to a screen size of the blade separator. This not only simplifies maintenance and reduces downtime but also significantly improves and maximizes the cost-effectiveness and operational flexibility of the corresponding blade separator.

[0012] The main body can be manufactured as a single piece. This has the advantage, among others, of reducing assembly effort, as no individual segments need to be joined, thus minimizing, for example, the potential for assembly errors. The elimination of separate connection points also reduces wear. Furthermore, manufacturing can be carried out in a single production step, which lowers production costs and time.

[0013] The base body (and / or the separation element) can be rotationally symmetrical. The multiple segments can be identical. The multiple segments can be arranged rotationally symmetrically around the shaft mount. This has the advantage that the separation element can uniformly grip, turn, and loosen the material to be separated during rotation. This allows, for example, the most homogeneous separation of the material along the shaft to be achieved. Furthermore, it ensures a uniform mechanical load and stable contact of the separation element with the shaft and reduces dynamic imbalances during rotation.

[0014] The multiple segments can be connected to each other via at least one predetermined bending point. Preferably, a predetermined bending point can be provided (and / or formed) between each pair of adjacent segments (of the multiple segments). The connection via predetermined bending points advantageously allows the separation element to expand elastically and / or unfold for easy assembly and disassembly on the shaft. Furthermore, this eliminates, for example, the need for separate hinges or connecting elements, thus simplifying the design.

[0015] Alternatively, it is conceivable that the multiple segments could be formed separately from one another and connected to each other via at least one connecting element, e.g., at least one joint structure and / or a hinge. For example, a connecting element could be arranged between each pair of adjacent segments (of the multiple segments).

[0016] Between each of the multiple segments, a notch can be formed, preferably on an inner side of the shaft receptacle. In other words, the base body can have several notches, each of which can be formed between two of the multiple segments. Advantageously, the notches increase the elasticity of the separating element and thus facilitate its expansion or adaptation to the shaft. Furthermore, this simplifies assembly and disassembly and simultaneously enables a secure, positive-locking fixation on the shaft.

[0017] The cuts can be evenly distributed around the shaft receptacle. The cuts (and / or individual cuts) can begin on the inside of the shaft receptacle and / or extend radially (i.e., in the radial direction of the base body and / or the separating element). The cuts can extend radially outward from the shaft receptacle. The cuts can be, for example, linear, wedge-shaped, and / or V-shaped.

[0018] The base body can be elastically expandable. The base body can be made of (or consist of) a plastic, preferably polyethylene, and / or an elastic material. This advantageously allows for quick and tool-free assembly and disassembly of the separation element on the shaft. The use of plastic and / or elastic material can also, for example, reduce the weight of the separation element and facilitate handling.

[0019] A separation point can be provided (preferably precisely) between the multiple segments for unfolding the separation element and / or for radially opening the shaft receptacle (i.e., for opening in the radial direction of the base body and / or the separation element). This advantageously allows the separation element to be unfolded or the shaft receptacle to be radially opened, thus enabling the assembly or disassembly of the separation element without axially removing the shaft.

[0020] The separation point can be provided in place of (preferably exactly) a predetermined bending point and / or a cut. The separation point can form two free ends of the base body. The separation point can completely cut through the base body, preferably radially.

[0021] The separation point can be fixed by means of a releasable click, snap, and / or clamping mechanism (in particular, reversibly). In other words, the separation point can have a releasable click, snap, and / or clamping mechanism. The click, snap, and / or clamping mechanism can have complementary profile contours, which are preferably formed at the separation point and / or at two free ends of the base body. The click, snap, and / or clamping mechanism can be closed by a positive engagement with the complementary profile contours. This has the advantage that the separation element can be fixed quickly and securely without additional tools. Furthermore, the separation element can be easily released and reused if necessary.

[0022] It is conceivable that the separating element could include at least one recess for the engagement of an opening tool, e.g., needle-nose pliers. This recess could be located, in particular, in the area of ​​the separation point and / or the releasable click, latch, and / or clamping mechanism. This would advantageously facilitate the opening and closing of the separating element.

[0023] The separation element can be radially (i.e., in the radial direction of the at least one shaft) attached, mounted, and / or placed onto the at least one shaft of the blade separator. Advantageously, the separation element can be attached to the shaft without having to remove the shaft. This can be facilitated, for example, by the segmented or hinged structure of the base body and / or by an elastically expandable base body.

[0024] The separation element and / or the base body can have a multi-pronged and / or star-shaped outer contour (and / or form). Alternatively, or additionally, the outer contour of the separation element and / or base body can have several prongs and / or (e.g., scoop-like) projections. The prongs and / or projections can be evenly distributed circumferentially (i.e., in the circumferential direction of the base body and / or the separation element) and / or extend radially outwards (i.e., in the radial direction of the base body and / or the separation element). The outer contour can, for example, be rotationally symmetrical about a central axis of the shaft receptacle and / or the base body (or the separation element). It is conceivable that the outer edges of the prongs and / or projections could be rounded. The outer contour orThe shape can advantageously effect targeted carrying, loosening and / or conveying of the material during the rotation of the shaft, thereby preventing material clogging in the blade separator.

[0025] According to a further general aspect of the invention, a separation element is provided for a blade separator having at least one rotatable shaft. The separation element can be arranged on the at least one shaft for material separation.

[0026] The separation element comprises at least one support structure for the detachable attachment of a spacer element, preferably for the detachable attachment of a spacer element between two adjacent separation elements. The spacer element can be detachably attached along the at least one shaft to define a distance (and / or a screen size) between two adjacent separation elements. The spacer element can, for example, correspond to the spacer element as disclosed herein (below).

[0027] The present disclosure thus enables an additional securing mechanism for the separation element. The spacer element can contribute to further securing the separation element on the shaft, preventing it from unintentionally detaching from the blade separator shaft or rotating when installed. This can be achieved, for example, by a positive-locking engagement of the spacer element with the separator element's support structure, thus securing it axially and / or rotationally. This ensures a secure fastening of the separation element.

[0028] Furthermore, the installation of the spacer element is simplified because it can be attached not directly to the shaft, but to a raised or easily accessible support structure of the separation element. This significantly reduces installation effort and allows for quick and precise positioning of the spacer element. This enables the creation of defined distances between adjacent separation elements, which can be flexibly adapted to different operating conditions or materials being separated. Simultaneously, a positive-locking and / or force-locking fixation of the spacer element is enabled, ensuring a reliable and stable separation effect during operation.

[0029] The separation element can have an unsegmented base body or a base body as disclosed herein. The at least one support structure can be designed as part of the base body.

[0030] The at least one support structure can be designed as a projection that extends axially (i.e., in the axial direction of the support structure and / or the separation element) outwards and / or, in a fixed state, axially along the at least one shaft. This advantageously provides an enlarged, raised, and stable contact surface for the spacer element. This ensures secure fixation and precise alignment of the spacer element along the shaft.

[0031] The at least one support structure can be designed as part of the base body (in particular the separation element as disclosed herein) or project axially (i.e. in the axial direction of the support structure and / or the separation element) beyond the base body.

[0032] The at least one support structure can have an axial length that corresponds to a maximum of half the axial length, preferably exactly half the axial length, of the spacer element.

[0033] The projection (and / or at least one supporting structure) can be designed, at least in sections, as annular, cylindrical, and / or flanged. This advantageously provides a large, stable support surface for the spacer element and distributes the forces evenly. This improves the fixing, reduces point loads, and increases the operational reliability of the separation element and the spacer element.

[0034] The at least one support structure can form a rotationally symmetrical arrangement relative to a central axis of the separation element. The shaft receptacle can be formed section by section within the at least one support structure.

[0035] The at least one support structure can have a contact surface for the positive-locking positioning and / or detachable fastening of a spacer element. Preferably, the contact surface can be positive-locking and / or at least partially form-fitting to the spacer element (or a contact surface of the spacer element). This can advantageously enable precise and repeatable alignment of the spacer element. Furthermore, the positive-locking or form-fitting design prevents slippage or rotation during operation, which increases the functional reliability and service life of the connection between the spacer element and the separation element.

[0036] The contact surface can be formed circumferentially (i.e., in the circumferential direction of the support structure and / or the separation element) and / or radially (i.e., in the radial direction of the support structure and / or the separation element) on the outside of at least one support structure (and / or the separation element). This has the advantage that the contact surface is easily accessible, which simplifies the assembly and disassembly of the spacer element. Furthermore, this arrangement enables stable fixing and optimized force transmission between the separation element and the spacer element.

[0037] The at least one support structure can be segmented and / or comprise multiple support sections. Each of the multiple support sections can be formed on (or as part of) one of the multiple segments of the base body. Each of the multiple support sections can be integrally formed with one of the multiple segments of the base body. The multiple support sections can form the at least one support structure when (or by) connecting the multiple segments of the base body.

[0038] The separation element can comprise two support structures. The two support structures can be aligned in opposite axial directions of the separation element and / or be formed at opposite axial end regions of the separation element. The two support structures can be opposite each other and / or arranged as mirror images of each other.

[0039] By incorporating two support structures on the separation element, it is possible to secure it from both sides using spacers, thus further improving the stability of the separation element on the shaft. For example, this prevents the separation element from shifting from its position along the shaft under high loads or vibrations.

[0040] The contact surfaces of the two support structures can be similar and / or symmetrical to each other. The two support structures can be similar and / or identical.

[0041] According to a further general aspect of the invention, a spacer element is provided for a paddle separator, which has at least one rotatable shaft with several separation elements arranged side by side in the axial direction of the at least one shaft. The spacer element is detachably fastened along the at least one shaft to define a distance (and / or a screen size) between two adjacent separation elements (of the separation elements arranged side by side).

[0042] The spacer element comprises a base body made up of several segments which are detachably connected or (detachably) connectable to form a receptacle. The receptacle is designed as an opening for detachable fastening to the at least one shaft or to a support structure (in particular a support structure as disclosed herein) arranged between the at least one shaft and the spacer element.

[0043] The present disclosure provides a simple solution for attaching or replacing the spacer element on the shaft of a blade separator. The spacer element's detachable mounting—either directly on the shaft or on a support structure located between the shaft and the spacer element—allows for quick and easy replacement without the need to disassemble the shaft or adjacent separation elements. Furthermore, the spacer element can be positioned at different locations along the shaft to flexibly adjust the spacing, i.e., the screen size, between adjacent separation elements to accommodate different material properties and separation requirements. This simplifies maintenance, reduces downtime, and significantly increases both the cost-effectiveness and operational flexibility of the blade separator.

[0044] The base body can be ring-shaped and / or cylindrical. The multiple segments can be shell-shaped, e.g., as half-shells. This advantageously enables a positive-locking and stably positionable connection to the support structure or shaft. Furthermore, the spacer element can be mounted radially on the shaft or the separating elements without requiring axial access to the shaft. This facilitates subsequent installation or replacement without the need to disassemble the shaft.

[0045] The multiple segments can be detachably connected or joined to one another by means of at least one releasable fastener, preferably at least one screw. This advantageously enables a stable yet easily re-fastening connection. As a result, the spacer element can be easily opened for assembly, disassembly, or replacement without damaging any components, and the segments can be individually replaced or reused as needed.

[0046] The base body (in a closed and / or connected state of the spacer element) can have a closed and / or at least partially rounded outer contour. The outer contour can be circular (e.g., with flattened areas at through-openings for detachable fasteners). The multiple segments can, in a connected state, lie flush against each other (at least partially).

[0047] The base body (and / or the multiple segments) can comprise (or consist of) a metal, preferably aluminium, and / or a plastic, preferably polyethylene.

[0048] The multiple segments can be detachably connected or joined to one another by means of several detachable fasteners, preferably several screws. The detachable fasteners can be arranged opposite and / or parallel to each other. The detachable fasteners can run axially apart from each other along a common plane. The detachable fasteners can run perpendicular to a dividing plane of the segments.

[0049] The releasable fasteners can clamp the multiple segments (of the spacer element) together by force and / or form locking. The releasable fasteners can be designed to completely close the spacer element and / or to completely enclose the support structure and / or the shaft.

[0050] The base body (and / or its segments) may have multiple through-openings. These through-openings may be designed for the passage and detachable fastening of detachable fasteners. The detachable fasteners may be guided (and / or guided) through two mutually aligned through-openings (of the multiple through-openings). The multiple through-openings may be formed by corresponding bores in at least two segments.

[0051] Metal inserts, such as metal cylinders, can be provided in the through-holes. This has the advantage of improving the securing of detachable fasteners, such as screws.

[0052] The through-openings may contain coils, preferably corresponding to coils of the detachable connecting elements.

[0053] The multiple openings can be opposite and / or parallel to each other. At least two of the openings can be aligned with each other when the spacer element is closed. The openings can be located on opposite sides of the spacer element.

[0054] The multiple through-openings can be formed on the end face of the spacer element and / or the multiple segments. The multiple through-openings can be formed in a plane extending transversely to an axial axis of the spacer element and / or in the transverse direction of the spacer element.

[0055] The spacer element can be configured to abut a support structure of the separation element, preferably two support structures of two adjacent separation elements simultaneously. The spacer element can also be configured to encompass a support structure of the separation element, preferably two support structures of two adjacent separation elements simultaneously.

[0056] It is conceivable that the multiple segments (of the spacer's base body) can be segmented and / or comprise multiple sub-segments. The multiple sub-segments (each of one of the multiple segments) can be connected to each other, for example, via at least one predetermined bending point and / or via at least one connecting element (e.g., at least one joint structure and / or a hinge). Alternatively, or additionally, a notch can be formed between each of the multiple sub-segments, preferably on an inner surface of the receptacle.

[0057] According to a further general aspect of the invention, a system for a blade separator, which has at least one rotatable shaft, is provided. The system comprises several separation elements as disclosed herein, and at least one spacer element, preferably at least one spacer element as disclosed herein. The at least one spacer element is arranged, or can be arranged, at least sectionally between two of the several separation elements.

[0058] The present disclosure provides a system in which separation elements and spacing elements are optimally matched to each other.

[0059] The arrangement of the spacer element between each pair of separation elements allows one spacer element to secure two separation elements simultaneously to the shaft of the blade separator, so that they are held axially and / or rotationally secure.

[0060] Furthermore, the arrangement allows for precise determination of the distance between the two separation elements and thus the screen size, thereby controlling the material flow of the material to be separated, preventing material build-up, and improving the separation performance of the paddle separator. This modular arrangement also allows for easy adaptation to different material properties and operating conditions, simplifying maintenance and conversion, and increasing and maximizing the system's flexibility and cost-effectiveness.

[0061] The at least one spacer element can be arranged or arranged on any two support structures of the two or more separation elements. The at least one spacer element can encompass any two support structures of the two or more separation elements.

[0062] The system can comprise multiple separation elements, preferably multiple separation elements as disclosed herein, and multiple spacer elements, preferably multiple spacer elements as disclosed herein. The multiple separation elements and the multiple spacer elements can be arranged or arranged alternately (preferably at least sectionally) next to each other.

[0063] The embodiments, variants, and features of the invention described above can be combined with one another as desired. In particular, the embodiments, variants, and features of the various aspects of the invention can be combined with one another as desired, including the various general aspects of the separation element. Further details and advantages of the invention are described below with reference to the accompanying drawings. These show: Fig. 1 and Fig. 2 schematic views of exemplary paddle separators. Fig. 3 Schematic view of a separation element in a closed state according to an embodiment of the present disclosure; Fig. 4 Schematic view of a spacer element in a closed state according to an embodiment of the present disclosure; Fig. 5. Schematic view of the separation element and the spacer element attached to the separation element; and Fig. 6 a schematic view of a system consisting of the spacer element and two separation elements.

[0064] The embodiments shown in the figures are at least partially identical, so that similar or identical parts are provided with the same reference numerals and, to avoid repetition, reference is also made to the description of the other embodiments or figures for their explanation.

[0065] Fig. 1 and Fig. Figure 2 schematically shows two exemplary paddle separators 100 and 100A. The paddle separators 100 and 100A are devices for the mechanical separation of materials or material mixtures, comprising at least one rotatable shaft, usually several parallel shafts, on which multiple separation elements 10 are arranged axially side by side. During rotation, the separation elements 10 convey, turn, and loosen the material so that smaller material fragments fall through the gaps formed between them, while larger material fragments are conveyed further. The gaps between each pair of adjacent separation elements 20 form corresponding passages for the material to be separated, with these gaps defining the corresponding screen size of the respective paddle separator 100 or 100A.

[0066] The two blade separators shown, 100 and 100A, represent different embodiments of the housing 110, 110A and the blade of the blade separator 100, 100A, respectively. The housing shape can be adapted to the specific operating environment and the material to be separated, e.g., with varying contours, recesses, and / or volumes for receiving and guiding the material.

[0067] Fig. Figure 3 schematically shows such a separation element 10 according to an exemplary embodiment. The separation element 10 can be advantageously arranged on a shaft of a blade separator 100, 100A for material separation.

[0068] The separation element 10 comprises a base body 12 made up of several segments 12-1, 12-2, 12-3, 12-4, which are connected (or connectable) to form a shaft receptacle 11. The shaft receptacle 11 is designed as an opening for detachable fastening to a rotatable shaft.

[0069] The multiple segments 12-1,...,12-4 can be connected to each other via at least one predetermined bending point. Alternatively, or additionally, a notch 16-1, 16-2, 16-3 can be formed between the multiple segments 12-1,...,12-4, preferably on an inner side of the shaft receptacle 11.

[0070] The at least one predetermined bending point can be designed, in particular, as a targeted reduction or narrowing of the base body 12 in a region between two adjacent segments 12-1, ..., 12-4. This reduction or narrowing can be formed by the respective cut 16-1, 16-2, 16-3, thereby achieving a local weakening of the material, which facilitates the elastic expansion or compression of the base body 12 and thus supports the assembly and disassembly of the separation element 10 on the shaft.

[0071] The base body 12 can be elastically expandable. This can be achieved, for example, by forming at least one predetermined bending point and / or at least one incision 16-1, 16-2, 16-3. Alternatively, or additionally, this can be achieved by selecting the material of the base body 12, in particular an elastic material and / or a plastic.

[0072] A separation point 14 can be provided (preferably precisely) between the multiple segments 12-1, ..., 12-4 for unfolding the separation element 10 and / or for radially opening the shaft receptacle 11. The separation point 14 can be arranged at a selected location on the base body 12 instead of a predetermined bending point and / or a cut 16-1, 16-2, 16-3. This arrangement completely cuts through the base body 12 in this area, so that in the open position, two spaced-apart free ends of the base body 12 are present, allowing the separation element 10 to be easily attached to or removed from the shaft.

[0073] The separation point 14 can be fixed by means of a releasable click, snap and / or clamping fastener 15. In this way, the free ends of the base body 12 formed at the separation point 14 can be connected to each other in the closed position by means of a positive and / or force-fit connection, so that the separation element 10 can be securely fixed to the shaft.

[0074] The separation element 10 can comprise at least one support structure 13 for the detachable fastening of a spacer element 20, preferably for the detachable fastening of a spacer element 20 between two adjacent separation elements 10. The at least one support structure 13 expediently serves as a connecting element between the separation element 10 and the spacer element 20 and enables a defined and releasable arrangement of the spacer element 20 along the shaft.

[0075] The at least one support structure 13 can be designed as a projection extending axially outwards, e.g., beyond the axial boundary of the base body 12, and / or extending axially along the shaft in the fixed state. The projection can be at least partially annular, e.g., for the uniform contact of a circular spacer element 20. Furthermore, it is conceivable that the projection could be designed in the form of a flange to create a larger contact and bearing surface.

[0076] The at least one support structure 13 can further have a contact surface 17, which serves for the positive-locking positioning and / or the releasable fastening of the spacer element 20. The contact surface 17 can be designed to be positive-locking and / or at least partially form-fitting to the geometry of the spacer element 20 in order to ensure, for example, a rotationally secure and precisely positioned connection of the spacer element 20.

[0077] The mounting surface 17 can be arranged circumferentially and / or radially on the outside of the support structure 13, so that the spacer element 20 is accessible from the outside and easy to mount.

[0078] In the Fig. In the embodiment shown in Figure 3, the base body 12 consists of exactly four segments 12-1, 12-2, 12-3, and 12-4, which are arranged in an arc around the shaft receptacle 11. Three incisions 16-1, 16-2, and 16-3 are evenly distributed and begin on the inside of the shaft receptacle 11, thereby achieving symmetrical elasticity of the base body 12. The separation point 14 extends completely through the base body 12 and is provided with a releasable click, snap, and / or clamping fastener 15, which, in the closed position, enables a positive locking fixation of the separation element 10 on the shaft. The at least one support structure 13 is designed as a radially projecting element that extends in the axial direction of the shaft and allows for a defined positioning of a spacer element.

[0079] The in Fig. The spacer element 20 shown in Figure 3 represents a combination of different aspects of the invention. For the purposes of this disclosure, the spacer element 20 can, for example, also comprise a base body 12 with several segments 12-1,...,12-4 and no support structure 13, or comprise an unsegmented base body and at least one support structure 13.

[0080] Fig. Figure 4 schematically shows a spacer element 20 according to an exemplary embodiment. The spacer element 20 is expediently fastened to define a distance between two adjacent separation elements 10 along the shaft.

[0081] The spacer element 20 comprises a base body 22, which consists of several segments 22-1 and 22-2. The segments 22-1 and 22-2 are detachably connected or connectable to form a receptacle 21. The receptacle 21 is designed as an opening that allows for detachable fastening either directly onto the shaft or onto a support structure arranged between the shaft and the spacer element 20, in particular the support structure 13 of the separation element 10.

[0082] The basic body 22 can in particular be ring-shaped and / or cylindrical, or the several segments 22-1, 22-2 can be shell-shaped.

[0083] The segments 22-1, 22-2 can be connected by means of at least one detachable fastener, preferably by at least one screw 23-1, 23-2, which allows for easy assembly and disassembly of the spacer element 20. The detachable connection allows the spacer element 20 to be subsequently inserted into an existing arrangement or replaced if necessary, without having to disassemble adjacent separation elements 10 or other components, in particular the entire shaft.

[0084] In the Fig. In the embodiment shown in Figure 4, the base body 22 consists of two segments 22-1, 22-2 designed as half-shells, which together form the annular receptacle 21. The connection is made via two opposing screws 23-1 and 23-2, which serve as releasable fasteners. By tightening the screws 23-1, 23-2, the two segments 22-1, 22-2 are joined together in a form-fit and force-fit manner, so that the spacer element 20 is securely fixed to the support structure 13 of the separation element 10 or to the shaft of the blade separator 100, 100A.

[0085] Fig. Figure 5 schematically shows a separation element 10 with a spacer element 20 arranged on it, which is attached to a support structure 13 of the separation element 10.

[0086] The spacer element 20 rests as precisely as possible on a radially outer contact surface 17 of the support structure 13, which is formed on the separation element 10. The spacer element 20 consists of two segments 22-1 and 22-2, which are detachably connected to each other. When connected, the segments 22-1 and 22-2 form the closed receptacle 21, which surrounds the support structure 13 and secures the spacer element 20 to the designated contact surface 17 by means of a positive and / or non-positive locking mechanism. This holds the spacer element 20 in a defined position on the separation element 10 and secures it against rotation.

[0087] Fig. Figure 6 schematically shows a system 30 for a blade separator 100, 100A, wherein the system 30 comprises two separation elements 10 and a spacer element 20. The spacer element 20 is arranged at least sectionally between the two separation elements 20.

[0088] The spacer element 20 is positioned axially between the two separation elements 10 and encompasses two support structures 13, each formed on one of the two adjacent separation elements 10. The support structures 13 are designed to be received into the receptacle 21 of the spacer element 20.

[0089] The spacer element 20 consists of two segments 22-1, 22-2, which are detachably connected to each other by means of screws 23-1, 23-2. The screws 23-1, 23-2 are guided through associated through-openings 24-1, 24-2. In the fastened state, the segments 22-1, 22-2 form the closed receptacle 21, which encloses both support structures 13 of the adjacent separation elements 10.

[0090] The inner contour of the receptacle 21 is form-fitting and / or at least partially adapted to the outer contours of the support structures 13. This ensures that the spacer element 20 rests with a defined position on the contact surfaces 17 of the support structures 13 of both separation elements 10.

[0091] The illustration depicts the composition of system 30, which consists of several detachably connected components that can be mounted along a common shaft and provide defined distances for material separation. System 30 is designed using modular units and can also include several separation elements 10 and several spacer elements 20, which are arranged alternately next to each other in the axial direction of the shaft. The sequence of separation elements 10 and spacer elements 20 creates defined passages for material separation, with all elements being detachably connected to the shaft or to each other.
