Definitions

  • the present invention relates to a mixing blade, comprising a base part which can be fastened to a shaft and a detachable wearing element, according to the preamble of claim 1.
  • a corresponding mixing blade is from the NL 7502240 and the US 1,555,964 , which discloses a mixing blade according to the preamble of claim 1, known.
  • the tip and an adjacent part of the mixing blade are formed as a replacement element
  • Such mixing blades are intended for use in mixers in which granular, abrasive materials are processed.
  • Mixers which have one or more, arranged perpendicular to the mixing vessel bottom mixer shafts, which are arranged with a plurality of planes, radially extending mixing blades.
  • the mixing vanes are generally of substantially rectangular cross-section, which cross-sectional shape is sometimes also tapered towards the front edge of the mixing blade, so that the mixing vanes have the overall shape of a flat, one-sided rectangular trapezium.
  • the leading edge of the mixing blades is the front edge in the direction of rotation of the corresponding rotor, which comes into engagement with the material to be mixed with the rotor rotating in front of the remaining parts of the mixing blade.
  • the mixing blade main body generally consists of one piece and is made of a comparatively soft material, such as structural steel.
  • a brazed carbide plating or armor To protect against wear, the leading outer edges and the extreme end of the mixing blade and their immediate environment are protected by wear-resistant steel, a brazed carbide plating or armor.
  • the preferably by build-up welding applied armor may for example consist of a hard, wear-resistant coating, such as a tungsten carbide-containing alloy.
  • the thickness of the armor is adapted to the effect on the mixing blades, locally different wear effects.
  • mixing blades In some known mixing blades is considered disadvantageous that they are often interchangeable only as a whole.
  • the replacement of the wear-resistant coating or armor is usually very expensive and can not be done in the installed state. For reprocessing, the mixing blades must therefore be completely removed.
  • the DE 200 04 488 describes a mixer blade attached to a support arm projecting radially from a mixer shaft, in particular a bottom blade for concrete mixers, with a detachable blade nose.
  • the mixing vanes are subject to wear during operation by the material flows flowing at different speeds above it. They are subject to a very different wear over the length of wear and wear preferably at its outer end, since there prevails the highest peripheral speed. In a knife-like beveled rectangular cross-section, however, next to the outer end of the mixing blade and the leading edge is exposed to a particularly high wear. This is especially true when coarse-grained products, such as broken rocks, are included in the mixture. Upon impact of such coarse-grained components on the front edge of the mixing tool, the narrower it is formed, the greater the weight of the individual coarse-grained components and the harder these constituents are.
  • the product Due to the adjoining the edge, sloping surface of the wing, the product is deflected accordingly up or down.
  • the adjoining the slope region of the cross section is significantly less affected by wear than the leading edge including the beveled surfaces.
  • the underlying soft base material is all the more easily worn and subject to a very strong abrasion, which partly also covers areas behind still existing armor. This can cause whole parts of the wear protection and the body break out, which can lead to damage or even stoppages to downstream machines.
  • the complete mixing blades which are usually releasably attached to the central mixer shaft, must be replaced at regular intervals, even if only small parts of the mixing blade are worn down to the base material and the wear protection is still strong enough at other points.
  • a mixing blade with detachable tail solves the problem only partially, as it may well be that occasionally radially located within the releasable end portions of the mixing blade have experienced a greater wear. In such a case, however, the entire mixing blade must be replaced. Furthermore, at the joint by permanent impact stress by very coarse-grained products at the top of the mixing blade, a gap arise., Which clamps in fine product and leads to the elongation of the screw connection up to their failure. Also, when using a releasable end made of solid carbide and very high peripheral speeds due to the large centrifugal forces on the mixing tool to a strong elongation of the fasteners come up to their failure.
  • the present invention seeks to provide a mixing blade of the type mentioned, which has an overall improved economy.
  • the cross section of the wear element is tapered towards the front edge.
  • This knife-like design with sloping ramp surfaces contributes due to the vertical movement of the mix produced thereby to a particularly good mixing, wherein the sharp leading edges for a crushing of coarse-grained ingredients or agglomerates.
  • the front edge of the mixing blade is not “razor-sharp" in the narrower sense, but rather the edge is significantly narrower than the maximum thickness of the mixing blade (measured in the direction of the axis of the associated rotor) Thus, for example, only 1/4 to 1/20 (or less) of this thickness.
  • the wear element and the base have different cross sections and overlap in the longitudinal direction of the base over a larger portion of at least 30%, one can exchange a larger portion of the mixing blade, without causing the entire, remaining portion of the mixing blade over the full Cross-section must be removed or replaced.
  • the length of the base is measured from its radially inner, to be fastened to the shaft or corresponding support members end to the radially outer tip.
  • the wear element forms at least the radially outer third, preferably at least the radially outer half of the front edge of the mixing blade in the running direction.
  • the wear element next to the leading edge and the entire tip or the entire end of the mixing blade form and thereby cover the cross section of the tip of the base either completely or at least partially.
  • This embodiment makes it possible to replace the worn parts of a mixing blade, which usually includes the tail and the radially outer half of the leading edge, as needed, without the other parts, namely the main body of the mixing blade, must be replaced.
  • the replacement of wear elements can thus be limited to the parts or areas that are actually exposed to increased wear and the addition of the tail and the tip of the mixing blade and its leading edge at least in the radially outer 30% of the (radial) length of the mixing blade include.
  • the wear element is formed in several parts, and for example consists of a leading edge portion and an end portion or a tip of the mixing blade, which are separately attached to the base of the mixing blade.
  • the wear element in the plan view has a rectangular shape and fills a corresponding rectangular recess in the base part, wherein (partially to avoid notch loads), the corner areas are more or less rounded.
  • the wear element forms, for example, in plan view approximately the front half or the front third (respectively measured from the front edge) of the entire mixing blade, while the rear part of a mixing blade is formed by the main body, which is made of a less hard, but easier to work Material can exist.
  • the wear element has in cross-section the shape of a rectangular trapezium, i. a trapezoid having a right-angled end and a tip tapering at a relatively small angle, wherein the tip defined thereby may also be somewhat bevelled or rounded.
  • connection between the wear element and base preferably takes place via bolts from the back of the base forth through holes in the base, the bolts engage in threaded holes in the back of the wear element.
  • the threaded holes can also be inserted or soldered threaded bushings.
  • the wear element defining the major part of the leading edge has a cross section decreasing from the tip of the blade in the direction of its radially inner end, while the base part has a correspondingly increasing cross section in the same area.
  • the cross section takes substantially only in the direction of the width of the mixing blade, i. in the direction measured from the front edge to the back direction.
  • the top plan view then yields the shape of a right-angled triangle with a relatively acute angle for the wear element. The acute angle end is closer to the radially inner end of the mixing blade, i. towards the wave. In this way, an even larger part of the harder and more expensive wear material can be saved, since the wear to the radially inner portions of the mixing blade towards decreases more and there correspondingly less wear material is needed.
  • a modification to this, but based essentially on the same basic idea, is a shape that appears in the plan view in approximately Z-shaped or in which, starting from the triangular shape just described, the two vertices of the triangle (with angles smaller than 90 °) are cut off.
  • a further variant has approximately an L-shape, wherein, however, the longer, the front edge of the mixing blade forming L-leg widened continuously in the direction of the second L-leg.
  • a third modification of the triangular basic shape (narrow wear body toward the center, which becomes progressively wider towards the outside) has a curved joint, thus replacing the hypotenuse of the triangular shape described first with a concave (or convex) arc.
  • FIG. 1 shows a mixer 1, which is in the preferred embodiment with a rotating mixing container 2, consisting of a round planar mixer bottom 3 and a cylindrical mixer wall 4, is provided.
  • the mixer further has an eccentrically arranged to the mixing vessel center, overhung, until just above the mixer bottom reaching rotor 5, which is arranged in several planes, radially extending mixing blades 6 carries with detachable wear element.
  • the mixing container 2 and the rotor 5 are rotated by drives (not shown) in rotation.
  • the cylindrical wall 4 and the mixer bottom 3 are stripped off by a stationary, combined wall bottom tool 7.
  • the emptying of the mixing container 2 takes place via the central bottom emptying opening 8.
  • the rotor 5 consists of a polygonal shaft (not shown), on which a plurality of tool holders 9 are arranged one above the other displaced.
  • the mixing blades 6 are mounted in pins (not shown) by means of the bore 11.
  • the column of tool holders 10 with mixing blades 6 is clamped by a suitable releasable connection for operation.
  • the mixing vanes 6 are integrally connected to the rotor 5. Also, it is not absolutely necessary for the effectiveness of the invention that the mixing container 2 rotates and the rotor 5 is arranged eccentrically in the mixing container 2.
  • the rotor 5 can also be arranged centrally with the mixing blades according to the invention in a stationary mixing container.
  • the mixing blade according to the invention could are used radially from a horizontally extending rotor, which is arranged in a horizontal stationary mixing container.
  • the mixing blade 6 in FIG. 2 consists of an approximately L-shaped base body 15 with a rectangular recess into which a corresponding, rectangular wear element 12 is suitably inserted.
  • the corner of the wear element located in the joining area, as well as the corresponding corner of the recess, is preferably strongly rounded off.
  • the mixing blade also has a total of the top plan view of the shape of an elongated rectangle, wherein the largest part of the front edge is defined to about the longitudinal center of the mixing blade 6 of the wear element 12.
  • the wear element 12 has, as one of the others also in the front view according to FIG. 3 recognizes, over most of its length, the cross-section of a right-angled trapezoid whose tip is slightly capped.
  • the wear element as a cuboid having on one side (optionally also on both sides) a significant bevel 13, so that there is a relatively narrow, knife-like leading edge for the wear element, and the bevel 13 a ramp surface for mixing Material forms.
  • FIG. 2 can be seen to the radially inner end toward a transition region in which the chamfer 13 increasingly smaller, so that the cross section of the wear member 12 at its inner end again assumes the shape of a rectangle, which also rectangular cross-section of the body 15 to a longer, narrow Rectangle added.
  • the inner end of the base 15 has the same narrow rectangular cross section that the wear element 12 and the base 15 (apart from the chamfer 13) together form.
  • the wear element accounts for about 20% bi 80%, preferably 30% to 70% and more preferably between 50% and 60% of the total width.
  • the detachable wear element 12 and the main body 15 of the mixing blade 6 are formed as separate components. As the FIGS. 2 to 10 clarify the components are releasably connected by suitable fasteners. The connection must be able to transfer the forces acting on the wear element 12 from the mix to the base body 15 of the mixing blade 6. In addition, the wear element 12 must be secured against rotation relative to the main body 15 of the mixing blade 6.
  • the detachable connection and securing against rotation can be achieved in various ways, for example by two or more screw connections 14 (FIG. Fig. 2 ), by one or more centering pins in conjunction with a screw connection or by an overlap of wear element and main body of the mixing blade ( Fig. 7 . Fig. 8 ), as well as with at least one releasable connection element.
  • the detachable wear element in the plan view from above has a substantially triangular shape.
  • the triangular wear element 12 has a width at the radially outer end 16, which corresponds to the total width of the mixing blade 6, and tapers therefrom inwardly towards a triangular point, in this case at about 40% of the total length of Blender wing 6 (measured from its radially inner end) ends.
  • This distribution of wear material with a mass of the material in the area of the tip and less and less wear material radially inward parts corresponds largely to the actual wear behavior in use, so that it can be assumed that after a certain time, when an exchange of the wear element 13 is due, this has over its entire length a related to the different amount of wear material at different radial positions uniform wear.
  • FIG. 5 an embodiment is shown in which the rectangular in plan view wear element 12 with respect to the provided for this wear element recess in the base body 15 of the mixing blade 6 has an excess, ie, both in the forward direction and in the radial direction over the adjacent edges and surfaces of the base 15 protrudes.
  • the rectangular wear element 12 could alternatively consist of several assembled rectangular or L-shaped parts.
  • a corresponding wear element 12 also in the vertical direction, ie in FIG. 5 perpendicular to the plane of the paper, beyond the adjacent surfaces of the base body 15 protrude, which results in the fact that the body 15 is much better protected against exposure to mix and thus better protected against wear, as in an embodiment, such as in connection with FIGS. 2 and 3 has been described.
  • the wear element 12 recess designed as a fold, so that in the lower region of the mixing blade body 15 still a board 20 has stopped, which serves as a support surface for the wear element 12.
  • Such an embodiment is particularly favorable when strong torques (with respect to the longitudinal axis of a mixing blade) act on the wear element or the mixing blade 6. If the wear element 12 is attached only with bolts, as exemplified in the Figures 2 and 5 is shown, so act in the case of such torques and very strong forces on the bolt connection.
  • the board 20 according to FIG. 7 absorbs such torques without the fastening screws 14 being excessively stressed.
  • the wear element 12 has at its front edge a downwardly projecting projection 28 which covers the front edge of the board 20.
  • the front edge of the wear member 12 can be made as sharp or narrow as in the example of FIG. 6 in that the wear element 12 is slightly lengthened with its dimensions in the forward direction or by the bevel 13 is set a little deeper or slightly steeper.
  • FIG. 8 a variant is shown in which the detachable wear element 12 has an L-shaped configuration in plan view and thus a better support is realized by a larger overlap and a larger connection surface between the base body 15 and wear element 12. At the same time, the entire radially outer edge at the end of the mixing blade with the same wear protection material is protected against wear.
  • a fastening 22 of the short L-leg on the front side of the base 15 of this short leg L acts simultaneously as rotation and relieves the bolts 14 when torques with respect to the longitudinal axis of the mixing blade 6 on the wear member 12 and the beveled surface 13 act ,
  • a preferred embodiment of the invention shows FIG. 9 ,
  • the detachable wear element 12 is combined at the leading edge with a detachable end piece 21 designed as a separate component.
  • the screw 22 of the tail takes place in the axial direction and is sunk as deep as possible in the end piece 21.
  • the counterbore 23 is closed by a suitable, removable removable filling 24.
  • the securing of the end piece 21 against rotation (about the axis of the bore 23) takes place here by overlapping 25 with the main body 15 of the mixing blade 6.
  • the releasable wear element 12 at the leading edge is inserted between the base body and end piece 21.
  • FIG. 10 A particularly preferred embodiment of the invention is shown in the isometric sectional view in FIG. 10 ,
  • the detachable wear element 12 at the leading edge covers only a part of the total length of the main body 15 and the mixing blade 6.
  • the attachment of the detachable wear element 12 takes place from the trailing edge of several screw 14.
  • a detachable end piece 26 designed as a separate component is connected flush.
  • the screw 22 of the end piece 26 takes place in the axial direction.
  • the securing of the end piece 26 against rotation takes place in this case by supporting an edge on the detachable wearing element 12.
