Definitions

  • the present invention relates to a mixer device according to the preamble of claim 1, with which mix of high viscosity and / or low homogeneity such as moist sand, gravel, split or even mortar or concrete loosen, mix and / or remove at one or more sampling points leaves.
  • the mixer means comprises a bottomed mixer drum and a plurality of mixer arms facing towards the bottom and drivable for rotational movement about a common axis of rotation, each mixer arm having a free end to which a mixer blade unit is attached adjacent to the bottom of the mixer drum which moves along a respective conveying direction to convey the mix in the respective conveying direction.
  • Such a mixer device is basically from the example EP 1 266 827 B1 known.
  • Such a mixing device is particularly suitable for use in a sandbag filling plant or a concrete mixing plant.
  • the invention is therefore based on the object to meet this need.
  • At least one of the mixer blade units has at least one contour which is defined by two transverse to the conveying direction opposite sides of the mixer blade unit, wherein the distance between the two contour sides varies ,
  • the respective mixer blade unit has a contour, ie an outline and / or a surface shape, which can be assigned transversely to the conveying direction two opposing sides whose distance is not approximately constant, but at least partially varied (in particular along the conveying direction the respective blender unit).
  • the conveying or flow resistance of the mixer blade unit can thus be reduced, so that a lower drive power is required for a predetermined rotational speed or the mixer device is faster with constant drive power to turn.
  • a smaller electric motor can be used, or the mixed material can be conveyed more quickly while the drive power remains constant, into removal openings formed in the mixer drum, which increases the efficiency of the bottling plant.
  • the effect, explained below, of a sharp rise of the conveyor or flow resistance at a Aufricht the mixer blade unit (compared to a preset angle of attack) can be reduced.
  • the aforementioned two contour sides of the mixer blade unit can be narrow sides (in particular edges) or broad sides (in particular surfaces).
  • the surfaces of said two contour sides of the mixer blade unit preferably run obliquely (ie at an angle not equal to zero) to the conveying direction, and depending on the embodiment, they may point obliquely in the conveying direction (such that during the rotary movement the respective surface impinges at least one directional component on the mixture).
  • the distance between the two contour sides preferably varies monotonically, i. along the conveying direction preferably takes place either only an increase in the distance or only a reduction in the distance between the two contour sides.
  • said contour of the mixer blade unit is preferably symmetrical with respect to the conveying direction (in particular symmetrical with respect to a plane spanned by the conveying direction on the one hand and an axis parallel to the axis of rotation by the mixer blade unit) so that the mix does not deflect laterally the mixer blade unit or the associated mixer arm causes.
  • the said contour of the mixer blade unit can also be formed asymmetrically with respect to the conveying direction.
  • a plurality of said contours may also be provided with varying spacing of the two contour sides on the same mixer blade unit, in particular a plurality of different such contours.
  • Said conveying direction of the respective (rotating) mixer blade unit generally points within the movement plane of the respective mixer blade unit in its (current) rotational movement direction.
  • the said two transverse to the conveying direction opposite contour sides of the mixer blade unit can be indirectly connected to each other via an (eg rectilinear or curved) front, or they can be angled directly merge into each other (eg in the form of a wedge), or they can continuously rounded into each other (for example, to jointly form a single rounding), but the wedge shape is preferred, as will be explained below.
  • at least two opposite sides of the contour can be identified which, however, are not necessarily sharply demarcated in the case of a rounded continuous transition.
  • the said two contour sides can run obliquely toward one another, preferably continuously, in order to effect a low flow resistance during the rotational movement of the relevant mixer blade unit.
  • the said two contour sides can preferably be formed in each case just.
  • a curved training of the contour pages is conceivable.
  • Said contour may be provided on a mixer blade of the mixer blade unit or on an attachment portion of the mixer blade unit configured to attach the mixer blade unit to the associated mixer arm, or on both a mixer blade and a mounting portion of the mixer blade unit.
  • a single common Kontor of the aforementioned type may be provided, or two contours may be formed separately from each other and the same, or separately from each other and different.
  • the mixer blade unit has a mounting portion, by means of which the mixer blade unit (or said mixer blade) can be attached to the associated mixer arm, wherein the attachment portion has a (preferably obliquely) pointing in the conveying direction front surface, wherein the front surface of the attachment portion has two surface portions which are angled relative to one another and perpendicular to the direction of conveyance, to form said two contour sides of the mixer blade unit.
  • the two relative to each other angled surface portions of the mounting portion may thus form a common ridge, which preferably extends in the direction of the mixer arm.
  • the mixer blade unit in the region of its attachment portion has a pitched roof-like shape, whereby a kind of clearing blade is formed, with which the mix can be at least partially pushed aside, instead of pushing it in front of the mixer blade ago.
  • the said two surface portions of the attachment portion may also be connected to each other only indirectly.
  • the attachment portion of the respective mixer blade unit may comprise a mounting sleeve which receives the free end of the mixer arm, wherein said two contour sides of the mixer blade unit formed as an integral part of the mounting sleeve or placed on the mounting sleeve and firmly connected to the mounting sleeve (eg welded).
  • the said two relative to each other angled surface portions may be formed by a roof-shaped angle profile which is fixedly connected to the mounting sleeve and which forms a preferably extending in the direction of the mixer arm ridge.
  • the transversely to the conveying direction convexly curved front surface of the attachment portion may be formed by a longitudinally cut pipe section (eg with a part-circular or maschinellipsenförmigen Cross section), which is fixedly connected to the fastening sleeve, whereby the fastening sleeve is provided with a convexly curved profile.
  • a longitudinally cut pipe section eg with a part-circular or erllipsenförmigen Cross section
  • the mixer blade unit can have a mixer blade which has two lateral edges which are opposite to the conveying direction and which have the two contour sides of the mixer blade unit or of the mixer blade and which are angled relative to each other so that the width of the mixer blade varies with decreasing distance from the free end of the associated mixer blade, preferably decreases.
  • the width of the mixer blade may decrease continuously or stepwise as the distance from the free end of the mixer arm decreases.
  • the two side edges are preferably aligned symmetrically with respect to the conveying direction.
  • the mixer blade may have the shape of a trapezoid, and preferably that of an isosceles trapezium. Compared to a rectangular mixer blade thus exposed to the mix surface of the mixer blade is reduced, whereby the flow resistance of the mixer blade or the mixer blade unit can be kept small in the desired manner.
  • the mixer blade between the two said side edges has a rectilinear front edge, which is aligned parallel to the bottom of the mixer drum. In particular, this front edge may form the basis of the aforementioned trapezoidal shape.
  • the mixer blade may have a front surface (preferably obliquely) in the conveying direction, wherein the front surface of the mixer blade may have two surface sections which are angled relative to one another and transverse to the conveying direction to form said two contour sides of the mixer blade unit; or wherein the front surface of the mixer blade is convexly curved transversely to the conveying direction to form said two contour sides of the mixer blade unit.
  • the two surface portions may form a common ridge, which preferably extends in continuation of the associated mixer arm.
  • the mixer blade thus has a sort of saddle-roof-like shape and thus acts as a kind of clearing blade. Due to a wedge-shaped shape of the mixer blade, this displaces the mix at least partially to the side, so that the mixer blade in the conveying direction less mix has to push in front of him, with the result that less force is needed to move the mixer blade unit through the mix.
  • the two relatively angled surface portions of the front surface of the mixer blade (instead of angled directly to each other into one another) may also be connected only indirectly.
  • two opposing sides can be identified along the curvature transverse to the conveying direction, the distance of which varies (and in particular decreases along the conveying direction). This does not rule out that these two contour sides are continuously merged. Also in these embodiments, the two contour sides formed thereby are preferably formed symmetrically with respect to the conveying direction.
  • the mixer arms themselves can also have a deflection contour, preferably in the form of a wedge cross-section tapering in the conveying direction, in the area of their front side (which is exactly or obliquely) in the conveying direction, so that also by the mixer arms themselves, the mix is at least partially pushed aside, instead of pushing it in front of the mixer arms.
  • the mixer arms may be formed resiliently with respect to the conveying direction, wherein they are preferably elastically flexible in itself.
  • the mixer arms can be fastened to a mixer cross which can be driven in a rotational movement, which is located in the region of the opening of the mixer drum which is axially opposite the bottom and which has a plurality of legs, each of which carries one or more mixer arms.
  • each mixer blade unit (and in particular the already mentioned mixer blade of the respective mixer blade unit) is inclined by an angle of attack relative to the plane of the bottom of the mixer drum in the idle state of the mixer device (ie if the respective mixer blade unit does not experience a delivery resistance) this angle of attack can be, for example, in the range between approximately 20 and 60 °.
  • This also makes it possible to reduce the drag coefficient of the mixer blade unit, since the mixer blade unit, due to its orientation inclined with respect to the plane of the bottom of the mixer drum, offers resistance to the mix only with its surface component facing in the conveying direction.
  • the mixer drum itself may preferably have a cylindrical, cup-shaped shape with a flat bottom, in which a plurality of removal openings for removal of the mixed material are provided.
  • the sandbag filling system 10 has a support frame 14, on which a cylindrical mixer drum 13 is mounted, wherein the mixer drum 13 in turn carries a hopper 12, which facilitates the filling of material to be mixed in the mixer drum 13.
  • a plurality of removal openings 21 are formed along the circumference of the mixer drum 13, each of which is closed by a rotary valve 19 which can be manually transferred by means of an actuating arm 20 from the closed position to an open position.
  • a drive coupling 15 is also suspended, which is drive-connected to a vertical drive shaft 16 in the center of the mixer drum 13.
  • a vertical drive shaft 16 At the free end of the drive shaft 16 is in the Fig. 2 more precisely illustrated mixer cross 17 attached, the more radially aligned legs 22, to each of which at least one mixer arm 23 is fixed, said mixer arms 23, starting from the mixer cross 17 in the direction of the bottom 18 of the mixer drum 13, that extend downwards.
  • a mixer blade unit 25 is attached.
  • To the drive coupling 15 can be coupled to a drive shaft such as the propeller shaft of a tractor so as to enable the drive shaft 16 of the sand bag filling system 10 and thus the mixer cross 17 together with the mixer arms 23 attached thereto in rotation.
  • the sandbag filling system 10 may also have its own drive unit (eg electric motor).
  • the mixer blade units 25 are moved along a respective conveying direction R (cf. Fig. 2 ) emotional.
  • the conveying direction R generally points within the plane of movement of the respective mixer blade unit 25 (which is perpendicular to the axis of the drive shaft 16 and perpendicular to the plane of the paper according to FIG Fig. 1
  • the mixed material received by the mixer drum 13 is loosened, mixed and / or conveyed in the circumferential direction and radially outward in the direction of the removal openings 21 formed in the bottom 18 of the mixer drum 13.
  • Fig. 2 it may be, for example, so-called spring tines of S-shaped shape in the mixer arms 23, which can escape elastically against the conveying direction R, if this acts on an excessively large resistance through the mix.
  • spring tines of S-shaped shape in the mixer arms 23 which can escape elastically against the conveying direction R, if this acts on an excessively large resistance through the mix.
  • the mixer arms 23 Due to the elasticity of the mixer arms 23 and the orientation of the free ends of the mixer arms 23 at said angle, thus the mixer arms 23 can be elastically deflected at large resistors, which are applied by the mix until the free ends of the mixer arms 23 including the attached thereto Mixer blade units 25 are aligned substantially perpendicular to the bottom 18 of the mixer drum 13. This deflection or retraction of the mixer arms 23 is connected to a corresponding raising of the respective mixer blade unit 25 (increase in the angle of attack).
  • the mixture is still reliably loosened, mixed and / or promoted even with large resistors that act on the rotating mixer arms 23 of the mix, still reliable.
  • the discharge resistance may undesirably increase (as the surface-facing component of the mixer blade unit 25 becomes larger in the conveying direction).
  • this effect can be reduced by the embodiment of one or more of the mixer blade units 25 explained below.
  • the mixer blade unit 25 has a mixer blade 26, which is attached to a mounting portion 24 in the form of a fastening sleeve 27, for example by welding.
  • the sleeve 27 serves to attach the mixer blade unit 25 at the free end of a mixer arm 23.
  • the fastening sleeve 27 is attached to the free end of a mixer arm 23 and secured by a fastening screw 28, which screwed thereto by a trained in the wall of the mounting sleeve 27 threaded opening becomes.

  • a power saving of about 30% can be achieved.
  • the two transverse to the conveying direction R opposite side edges 29a, 29b of the mixer blade 26 have a stepped shape, so that the distance between the two contour sides 29a, 29b gradually decreases starting from the free end 30 of the mixer blade 26 , Further, the side edges 29a, 29b of the mixer blade 26 could also be curved (instead of the rectilinear course shown).
  • the mixer blade 26 Due to the trapezoidal configuration of the mixer blade 26, which is inclined in said angle of attack, and in particular by the two side edges 29a, 29b which are angled relative to one another, the mixer blade 26 has a contour whose width along the conveying direction R (FIG. Fig. 2 ) varies continuously.
  • the mixer blade 26 in the illustrated embodiment has a flat shape in the form of a plate, it is also possible to bend the trapezoidal (or contoured) mixer blade 26 so as to be transverse to the conveying direction R (FIG. Fig. 2 considered) has two surface portions which are angled relative to each other and form a common ridge extending, for example, in continuation of the mixer arm 23 (not shown in the drawings).
  • the mixer blade 26, contrary to the illustrated embodiment also have a pitched roof-like, spatial shape, wherein the ridge of the saddle roof in continuation of the free end of the mixer arm 23 extends.
  • the mixer blade unit 25 on the mounting portion 24 further has a roof-shaped angle profile 31, which is the mounting sleeve 27 upstream in the conveying direction R and placed on the mounting sleeve 27, wherein by the mutual connection of the legs of this angle profile 31 in the direction of Mixer arm 23 extending ridge 32 is formed.
  • the mixer blade unit 25 thus has, in the region of the attachment section 24, two surface sections 33a, 33b which are angled relative to one another in order to form the common ridge 32.
  • the mixer blade unit 25 in the region of its attachment portion 24 has a pitched roof-like shape as a dozer blade, which can also achieve a power saving of about 30%.
  • the angle profile 31 thus has a contour which is formed by two mutually opposite sides 29c, 29d in the form of the two angle legs or surface portions 33a, 33b, wherein the distance between the two contour sides 29c, 29d varies (namely along the conveying direction R continuously decreases).

  • the mixer blade unit 25 Due to the inventive shape of the mixer blade unit 25 less driving force is thus required for mixing the mix, so that less powerful drive units such as drive vehicles, motors or power generators can be used. Since less force is needed to drive the mixer cross 17, lighter gear can also be used, and it can be approached the system even when filled from a standing position.
