Description

[0001] The invention relates to a centrifuge drum with a drum wall having a plurality of circumferentially distributed openings, according to the combination of features of claim 1. Furthermore, the invention relates to an outlet arrangement and a deflection component. Furthermore, the invention relates to a centrifuge with a centrifuge drum according to the invention.

[0002] Separator drums or centrifuge drums are well known in the art. Furthermore, various separator designs exist. In addition to manual separators, there are, for example, automatic self-emptying separators and jet separators. The specific separator type is selected depending on the separation task to be performed.

[0003] Nozzle separators are used, for example, for separating and simultaneously concentrating liquid mixtures. Due to their design, nozzle separators can process very large throughputs with very high solid concentrations. The incoming product is separated in the drum, with the specific gravity component of the mixture being transported radially outward toward the inner wall of the drum. The specific gravity components of the mixture, in contrast, are transported radially inward.

[0004] The accumulated solids are continuously discharged to the outside through outlet nozzles located in the drum wall. Since only a defined amount of solids can be discharged through a hole in the nozzle, the solids accumulate in front of this nozzle and are simultaneously concentrated. This concentrate is discharged radially outward through a channel formed in the nozzle.

[0005] Nozzles, specifically outlet nozzles for centrifuge drums, for example, have soldered-in carbide inserts. These carbide inserts are also known as nozzle blocks. Soldering such carbide inserts is a very complex process, requiring special preparation of the parts to be soldered and specialized knowledge of the soldering process. In addition to this aforementioned disadvantage, such special nozzles also have the disadvantage that their correct position must be ensured when changing the nozzles. Ensuring this alignment requires complex geometries in the drum base and the nozzle, as well as special tools for nozzle assembly.

[0006] CN 2 03 886 689 U describes a nozzle assembly for a separator, particularly designed for treating starch. The nozzle assembly essentially consists of a nozzle, a nozzle block, and a nozzle seat. The individual parts of the nozzle are screwed together and secured as a whole in the drum wall.

[0007] US 2024 / 0 066 529 A1 also discloses a nozzle arrangement with several partially nested components. Furthermore, a wear protection element is formed on the outer surface of the centrifuge drum.

[0008] Based on the aforementioned prior art, the object of the present invention is to provide a centrifuge drum which, in connection with the solids outlet, is further developed in such a way that nozzles can be exchanged in a simple manner, in particular if nozzles of a different size are to be installed, and on the other hand the outlet arrangement is designed to be wear-resistant.

[0009] A further object of the invention is to provide an improved outlet arrangement for forming an improved centrifuge drum. A further subordinate aspect of the invention is to provide an improved centrifuge.

[0010] According to the invention, this object is achieved with regard to the centrifuge drum by the subject matter of claim 1, with regard to an outlet arrangement by the subject matter of patent claim 12, with regard to a deflection component by the subject matter of patent claim 13 and with regard to a centrifuge by the subject matter of patent claim 14.

[0011] Advantageous and expedient embodiments of the centrifuge drum according to the invention are specified in the subclaims.

[0012] The invention is based on a first concept, according to which a centrifuge drum with a drum wall having a plurality of circumferentially distributed openings is provided, wherein an outlet arrangement comprising at least one nozzle and a deflection component is arranged in at least one opening, preferably in all openings. The deflection component is positioned in front of the nozzle in the outflow direction, starting from the interior of the drum toward the exterior of the drum, wherein the deflection component and the nozzle are two separate components.

[0013] In other words, the outlet arrangement comprises at least two individual components, namely at least one nozzle and at least one deflection component, wherein at least these two components are two individual components that can be handled independently of one another. Individual components are understood to mean, in particular, components that can be manufactured and / or stored independently of one another. Furthermore, individual components are preferably understood to mean components that are not part of the other component or of the at least one further component.

[0014] The outflow direction is preferably understood as the flow direction of the solids from the inside of the drum toward the outside of the drum. In other words, the outflow direction defines the path of the solids being carried out of the drum toward the outside of the drum.

[0015] In an opening of the drum wall of the centrifuge drum, the outlet arrangement is preferably designed such that the deflection component is positioned in front of the nozzle in the outflow direction.

[0016] Preferably, no further component is arranged between the deflection component and the nozzle.

[0017] A medium flowing out of the centrifuge drum, namely the solid, would first pass the deflection component and then the nozzle.

[0018] A centrifuge drum according to the invention is formed with a plurality of circumferentially distributed openings. The described outlet arrangement, which comprises at least one nozzle and at least one deflection component, is preferably arranged in all circumferentially distributed openings that serve for the drainage or ejection of the separated solid.

[0019] Since the deflection component and the nozzle are two independent components, the nozzle can be replaced without any further intervention on the deflection component. Replacing the nozzle does not necessarily require replacing the deflection component as well. Rather, the deflection component can remain in the opening in the drum wall.

[0020] Furthermore, the deflection component, as it is subject to greater abrasion than the nozzle, can be replaced at regular intervals or when it becomes worn. The nozzles are protected from wear by the design of a separate deflection component. Since the deflection component is preferably designed with a very simple structure, a component that is easy to manufacture and replace can be provided that is cost-effective in terms of wear. However, the higher-value component, namely the nozzle, does not need to be replaced every time a deflection component is replaced.

[0021] The deflection component has an inflow-side end face and an outflow-side stop surface. The nozzle is preferably designed to be adjacent to, and in particular to rest against, the stop surface. In such an embodiment of the invention, the stop surface of the deflection component can thus serve as the maximum stop for the nozzle to be inserted into the opening of the drum wall. When the nozzle rests against the stop surface of the deflection component, the installer is signaled that the nozzle has been inserted sufficiently deep into the opening of the drum wall.

[0022] If the nozzle rests against the stop surface of the deflection component, it is also prevented that a medium flowing out from the inside of the drum to the outside, in particular a solid to be ejected, can get into gaps, gaps or other free spaces between the nozzle and the deflection component.

[0023] The nozzle can preferably be positioned so that it rests against the stop surface of the deflection component in sections. In other words, the nozzle does not have to rest completely against the stop surface of the deflection component.

[0024] It is possible that the nozzle is positioned slightly spaced from the stop surface of the deflection component after assembly in the centrifuge drum. In particular, a gap may be formed between the stop surface of the deflection component and the nozzle in a first assembly state. Due to the use of the centrifuge drum and / or temperature fluctuations, the nozzle may, at least in sections, rest against the stop surface of the deflection component after assembly.

[0025] The deflection component serves, among other things, to partially deflect the outflowing material, in particular the solid material, from the drum interior toward the drum exterior. The deflection component can also be referred to as an outlet body or outlet component, wherein the outlet body or outlet component is positioned in front of the nozzle in the outflow direction, starting from the drum interior toward the drum exterior. The deflection component or outlet body or outlet component preferably forms a first section of an outlet arrangement, viewed in the flow direction. An outlet arrangement, in particular one according to the invention, can also be referred to as a solids outlet.

[0026] In the centrifuge drum, a shape that determines the outflow direction can be formed in the area of ​​the opening on the inside of the drum. It is possible for the shape to be in the form of a deflection section, whereby the underflow is deflected counter to the direction of rotation of the centrifuge drum. In combination with the deflection component of the outlet arrangement, the medium, in particular the solid, flows away or out.

[0027] The inflow end face of the deflection component can be inclined relative to the longitudinal axis of the deflection component and / or relative to the outflow stop surface. The inclined shape of the inflow end face preferably complements the shape of the inside of the drum in the area of ​​the opening into which the outlet assembly is inserted. This enables flow-optimized discharge of the medium, especially the solids.

[0028] The longitudinal axis of the deflection component is to be understood in particular as the longitudinal axis of a / the hollow cylindrical flow channel of the deflection component.

[0029] According to the invention, the inflow-side end face of the deflection component protrudes into the drum interior. Preferably, the inflow-side end face of the deflection component protrudes into the drum interior in such a way that the deflection component, at the inflow-side end of the deflection component, protrudes beyond the drum interior in a stepped manner. In other words, in such an embodiment of the invention, the inflow-side end face of the deflection component is not flush with the drum interior, but protrudes beyond this drum interior in a stepped manner toward the drum interior or in the direction of the rotational axis of the centrifuge drum.

[0030] This means that particles of the outflowing medium, in particular particles of the solid material, can settle around this step-like projection, which is formed between the inner surface of the drum and the inflow-side end face, so that the deflection component is additionally protected against wear at its inflow-side end. The protection is provided by particles of the abrasive medium itself. The step of the deflection component that projects into the drum interior is formed by the section of the outer surface of the deflection component that is formed between the inflow-side end face and the inner surface of the drum. With increasing distance between the inflow-side end face and the inner surface of the drum, which surrounds the opening in the drum wall, the extent of the step-like formation or the outer surface of the deflection component of the step-like section increases.

[0031] The outflow-side stop surface of the deflection component can be part of a flange. A flange is preferably understood to be a section of the deflection component that protrudes laterally at the outflow end, for example, beyond a tubular section.

[0032] In a particularly preferred embodiment of the invention, the flange is preferably designed to complement a recess or a recessed portion of the drum wall and rests in this recess or the recessed portion of the drum wall. The recess, or at least the recessed portion of the drum wall, is formed in the opening of the drum wall. Such a flange of the deflection component prevents the deflection component from slipping into the drum interior. No additional fastening elements are required for positioning and attaching the deflection component in the opening of the drum wall.

[0033] In a further preferred embodiment of the invention, it is possible for the outflow-side stop surface, in particular the flange, to have an outer circumference that corresponds to the contour of a complementary recess in the drum wall. By clearly and / or individually forming a bulge and / or indentation and / or locking lug and / or a shape that differs from the rest of the stop surface's geometry, this shape can enable the deflection component to be mounted in the correct position.

[0034] The outflow-side stop surface, in particular the flange, can have an outer circumference that defines a cam-shaped base surface. This cam-shaped base surface is preferably designed to complement a likewise cam-shaped recess in the drum wall. This enables a particularly simple structural option for correct mounting. Additional fastening elements are not necessary. In other words, the deflection component does not need to be fastened and / or fixed with additional fastening elements. Inserting the deflection component with a stop surface, in particular a flange, is entirely sufficient. Due, among other things, to this fastening option for the deflection component, the deflection component can be structurally designed and manufactured accordingly.

[0035] A hollow cylindrical flow channel is preferably formed between the outflow-side stop surface and the inflow-side end face of the deflection component.

[0036] The inflow-side end face of the deflection component preferably forms the inflow end of the outlet arrangement. The outflow-side stop surface or the outflow end of the deflection component, however, does not form the outflow end of the outlet arrangement. The outflow end of the outlet arrangement is preferably formed by the nozzle of the outlet arrangement. The hollow cylindrical flow channel is preferably formed by a circular cylindrical tube.

[0037] A rounded portion and / or chamfer and / or bevel can be formed in a transition area pointing from the inflow-side end face toward the outflow-side stop surface of the deflection component. Such a rounded portion and / or chamfer and / or bevel serves, in particular, to facilitate the insertion of the deflection component into the opening in the drum wall.

[0038] The previously described openings in the drum wall of a centrifuge drum are preferably formed in the drum base. The openings are preferably formed in sections of the drum base that are and / or form deflection sections for deflecting the media flow, in particular the solids flow. The deflection of the product flow occurs counter to the direction of rotation of the centrifuge drum.

[0039] The nozzle of the outlet assembly can have an external thread and be secured in the opening of the drum wall by means of the external thread. For this purpose, an internal thread complementary to the external thread is formed in the opening of the drum wall.

[0040] Because the nozzle and the deflection component are designed as separate components, the nozzle design can be simplified compared to the prior art. The formation of hard metal inserts or nozzle blocks can be omitted or simplified. Furthermore, in a preferred embodiment of the invention, it is no longer necessary to mount the nozzle in a specific orientation.

[0041] Rather, the nozzle can be designed in such a way that the outflow of the medium, in particular the solid, from the outlet arrangement, namely preferably from the nozzle, since the nozzle preferably forms the outflow-side end of the outlet arrangement, can take place without special specifications.

[0042] The deflection component can be made of a wear-resistant material, particularly hard metal. This material preferably does not need to be used for the nozzle. Due to the design of a separate deflection component, such wear protection is already provided, so the nozzle itself does not need to be designed with corresponding wear protection, as is known and required in the prior art.

[0043] A further aspect of the invention relates to an outlet arrangement for forming a centrifuge drum according to the invention. According to the invention, the outlet arrangement comprises a set that has at least one nozzle and at least one deflection component, wherein the deflection component and the nozzle are two separate components.

[0044] Regarding the design of the nozzle and / or the design of the deflection component, the previous explanations apply. This results in similar advantages to those already mentioned in connection with the centrifuge drum according to the invention.

[0045] A further aspect of the invention relates to a deflection component for forming a centrifuge drum according to the invention and / or for forming an outlet arrangement according to the invention.

[0046] According to the invention, the deflection component has an inflow-side end face and an outflow-side stop face, wherein the inflow-side end face runs obliquely in relation to the longitudinal axis of the deflection component and / or to the outflow-side stop face.

[0047] The previous explanations apply in connection with the deflection component according to the invention.

[0048] In connection with the deflection component according to the invention, similar advantages arise as those already stated in connection with the centrifuge drum according to the invention.

[0049] A further aspect of the invention relates to a centrifuge, in particular a disc separator, comprising a centrifuge drum according to the invention and / or an outlet arrangement according to the invention and / or a deflection component according to the invention.

[0050] In connection with the centrifuge according to the invention, similar advantages arise as those already stated in connection with the centrifuge drum and / or the outlet arrangement and / or the deflection component.

[0051] The terminology used in the description of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the subject matter. As used in this description and the claims, the singular forms "a," "an," and "the" are intended to include the plural forms, unless the context clearly dictates otherwise. The reverse is also true, meaning that the plural forms are intended to include the singular forms. It is also to be understood that the term "and / or," as used herein, refers to and includes all possible combinations of one or more of the related listed elements.

[0052] The invention is explained in more detail below using exemplary embodiments with reference to the attached schematic drawings. In these drawings: Fig. 1 a longitudinal section through a centrifuge drum according to the invention; Fig. 2 a perspective view of a deflection component according to the invention; and Fig. 3 a cross section through a centrifuge drum according to the invention with an outlet arrangement according to the invention located in an opening.

[0053] In the following, the same reference numbers are used for identical and equivalent parts.

[0054] Fig. Figure 1 shows a longitudinal section through a possible embodiment of a centrifuge drum 10 according to the invention. The centrifuge drum 10 has a drum wall 15. It can be seen that the centrifuge according to the invention is a disc separator, since the discs 11 are also indicated in the schematic representation.

[0055] In use, the centrifuge drum 10 rotates about the longitudinal axis L, which simultaneously forms the axis of rotation in the direction of rotation R. Openings 20 are provided in the drum wall 15. Through these openings 20, a medium, in particular a solid discharge, flows from the drum interior 12 toward the drum exterior 13. This occurs in the outflow direction A.

[0056] It can be seen that several openings 20 are formed in the drum wall 15. These openings 20 are located in bulges 16 of the drum interior 12. These bulges 16 form deflection sections of the drum interior 12. These bulges 16 are additional bulges relative to a circular circumference visible in the cross-section through the centrifuge drum 10.

[0057] In the circumferentially distributed openings 20 there is an outlet arrangement 30 with a nozzle 60 and a deflection component 40 (see Fig. 3). The deflection component 40 is in Fig. 2 can be seen in perspective.

[0058] The deflection component 40 has an inflow-side end face 41 and an outflow-side stop face 42. The inflow-side end face 41 is inclined relative to the outflow-side stop face 42. The inflow-side end face 41 is also inclined relative to the longitudinal axis LU of the deflection component.

[0059] The outflow-side stop surface 42 does not form the outflow-side end of the outlet arrangement 30, as shown in Fig. 3. Rather, the stop surface 42 serves, for example, to engage the nozzle 60 against the deflection component 40. The outflow-side stop surface 42 is part of a flange 44. The flange 44 projects beyond the tube 45 defining the hollow cylindrical flow channel 46. The tube 45 can also be referred to as a hollow cylinder. It can also be seen that the flange 44 has an outer circumference 47 defining a cam-shaped base surface.

[0060] The hollow cylindrical flow channel 46, or the tube 45 forming the hollow cylindrical flow channel 46, is formed between the inflow-side end face 41 and the outflow-side stop surface 42. At the outflow-side end 48, the tube 45 is surrounded by the flange 44. The deflection component 40 is preferably made of a wear-resistant material, such as hard metal.

[0061] A chamfer 51 is formed in a transition region 50 of the inflow-side end face 41, pointing toward the outflow-side stop surface 42 / in the direction of the flange 44. This chamfer 51 serves in particular as an aid when inserting the deflection component 40 into one of the openings 20. The outer surface 52 of the deflection component 40 is predominantly surrounded by the inside of the opening 20 in the installed state.

[0062] In Fig. 3 shows a section of a cross-section through a drum lower part 25 of a centrifuge drum 10. The cross-section is perpendicular to the longitudinal axis L of the centrifuge drum 10. Sectionally, an edge 17 is shown, which delimits the circular, hollow-cylindrical drum chamber section 18. Protrusions 16 are formed from this circular, hollow-cylindrical drum chamber section 18. The bulges 16 form a deflection section, so that a medium, in particular a solid, can flow in the outflow direction A through the opening 20 from the drum interior 12 towards the drum exterior 13. For this purpose, an outlet arrangement 30 is formed in the opening 20. The outlet arrangement 30 in the present case comprises a nozzle 60 and the deflection component 40. The deflection component 40 is designed as in Fig. 2, but in Fig. 3 in longitudinal section.

[0063] The components belonging to the outlet assembly 30, namely the deflection component 40 and the nozzle 60, are individual components that can be handled independently of one another. These components can be manufactured individually and independently of one another and can be replaced individually.

[0064] The inflow-side end face 41 or the inflow-side end 49 of the deflection component 40 simultaneously also forms the inflow-side end of the outlet arrangement 30. The outflow-side end of the outlet arrangement 30 is formed by the outflow-side end 61 of the nozzle 60. In the installed state, the flange 44 of the deflection component 40 rests against a recess section or a recess 21 of the opening 20. The recess 21 has an outer circumference that corresponds to the shape of the outer circumference 47 of the deflection component 40. This outer circumference preferably also delimits a cam-shaped base surface, so that the deflection component 40 can only be inserted into the opening 20 and rest in the recess 21 in a specific orientation.

[0065] In Fig. 3 shows that the inflow-side end face 41 of the deflection component 40 protrudes into the drum interior 12, in this case such that the deflection component 40 protrudes completely beyond the drum interior surface 14 at the inflow-side end 49. In other words, a gap is formed between the inflow-side end face 41 and the drum interior surface 14. Due to this completely protruding projection, the medium can be deflected from the drum interior 12 toward the drum exterior 13.

[0066] In Fig.3 also shows that the nozzle 60 rests with its end face 63 against the stop surface 26 of the drum base 25. This prevents the medium from flowing out sideways in the area of ​​the outflow-side stop surface 42 of the deflection component 40 or in the area of ​​the end face 63 of the nozzle 60. The stop surface 26 can serve, among other things, as a stop surface for the nozzle 60, specifically the end face 63 of the nozzle 60. Thus, when the nozzle 60 is screwed into the opening 20, a stop point for inserting this nozzle 60 is specified. The fitter can accordingly determine in which position the nozzle 60 is sufficiently inserted into the opening 20. The nozzle 60 can have an external thread for installation in the opening 20. This external thread can engage with an internal thread of the opening 20.

[0067] The hollow cylindrical flow channel 46 merges into a channel 62 of the nozzle 60 in the outflow direction A. Thus, starting from the inflow-side end face 41 to the outflow-side end 61 of the nozzle 60, a continuous outflow channel for the medium to be discharged (as a solid) is formed.

[0068] If the nozzle 60 is to be replaced with a different size (flow class), only the nozzle 60 can be replaced in conjunction with the outlet assembly 30. The deflection component 40 can remain unchanged in the opening 20. A new nozzle 60 can be inserted in place of the replaced nozzle.

[0069] If signs of wear are again detected on the deflection component 40, it is possible to remove the nozzle 60 from the opening 20, for example, by unscrewing it, remove the deflection component 40 from the opening 20, and then insert a new deflection component. The previously used nozzle 60 can be reinserted into the opening 20 after the deflection component 40 has been replaced.
