Definitions

  • the invention relates to a mixer which has, for example, a cylindrical container, a mixer arranged in the container and having a rotatably mounted shaft and mixing tools attached to radial arms, and at least one shredder mounted in the container wall, the shredding elements of the shredder being at such a distance of the container wall are arranged so that the mixing tools of the mixing mechanism can be moved between the container wall and the shredder and, accordingly, the tools and shredders do not interfere with each other, but complement their mode of operation.
  • the mixing tools are, for example, ploughshare-like, while the shredders are so-called knife heads which have straight or goblet-shaped knives one above the other in one or more planes, the shape and length of which are such that they are adapted to the plowshare-like mixing tools Envelopes are made so that the envelopes swept by the mixing tools and the envelopes of the shredders are closely matched to one another without overlapping, so that the parts cannot touch one another.
  • the invention has for its object to improve a mixer of the type mentioned in such a way that the disintegration of the mixed materials or the components thereof caused by the shredders is improved by a shear effect.
  • the invention provides a mixer which exerts a targeted shearing action on the mix which is fed to the shredders by the preferably ploughshare-like mixing tools.
  • the shredders have shear wreaths, which have a shearing and thus particularly advantageously shredding effect on the mixture, so that clumping is effectively avoided and any clumps that are formed are quickly and effectively dissolved.
  • the one shear ring of each shredder is preferably designed as a rotor and the other shear ring as a stator, so that only one of the two parts of the shear rings needs to be driven and thus moved.
  • the drive energy required can be kept low, while on the other hand the effort for storing the rotatable parts of the shredder is not unnecessarily high.
  • the mixer shown in the drawing has a fixed, i.e. a non-rotatably arranged cylindrical container (1) with flat end walls (2 and 3).
  • a shaft (4) extends through this container (1) in the axial direction and is rotatably mounted in bearings (5 and 6).
  • Ploughshare-like mixing tools (8) are attached to the shaft (4) on radial arms (7), which are located near the inner wall of the cylindrical container (1) and rotate in the direction of an arrow (9) in the container (1) when the shaft is from a motor, not shown, is driven.
  • the arms (7) of the ploughshare-like mixing tools (8) are staggered both circumferentially and in the axial direction, so that the mixed material caught by the ploughshare-like mixing tools (8) is tossed back and forth and thereby intensely swirled and thus mixed.
  • a shredder 10 is provided in the central area, which projects laterally into the container (1).
  • This shredder consists of a stator (11) and a rotor (12) which have shear rings (13 and 14) which are concentric with one another.
  • the stator (11) is arranged on a pipe section (15) which is fastened to the container (1) by means of a sleeve (16) fastened on the outside.
  • a spoke (17) is fastened, namely welded in the present case, which carries the shear ring (13) of the stator (11).
  • the shear ring (13) of the stator (11) has a number of radial slots (18) which extend over the part of the shear ring (13) which lies outside the spoke (17) and which are relatively narrow, so that between the rectangular or square slots (18) in plan view are relatively wide shear teeth (19) compared to these slots, as can be seen in particular in FIGS. 2 and 3.
  • the rotor (12) arranged concentrically within the stator is fastened to a shaft (20) which extends through the pipe section (15) and the wall of the container (1) and is driven in the direction of an arrow (21) by a motor (not shown) can be.
  • a motor not shown
  • the bearing of the shaft (20) is not shown in detail.
  • a spoke (22) is rotatably attached, which carries the shear ring (14) of the rotor (12).
  • This shear ring (14) contains relatively wide grooves (23), between which there are shear teeth (24).
  • the grooves (23) are not only wider than the practically radial grooves (18) of the outer shear ring (13), but also do not run radially, but at an angle or on a spiral path, so that both the grooves (23) and the shaving tools (24) in between have a trapezoidal layout.
  • the individual shear teeth (24) are thus equipped with a knife-shaped shear edge (25) which is located at the leading end of the shear ring (14) of the rotor (12) and with the inside of the teeth (19) of the fixed shear ring (13) of the stator interact in the grooves (18) between them and thus produce the desired shear effect when the rotor is driven.
  • the container (1) is provided at one end with a nozzle (26) serving as an inlet and at the opposite end with a nozzle (27) serving as an outlet.
  • a nozzle (26) serving as an inlet
  • a nozzle (27) serving as an outlet.
  • These sockets can be provided with connections or closures.
  • the mixer is for designed for continuous operation, but it can also be used in batch operation.
  • the teeth (19, 24) of the shear rings (13, 14) of the stator (11) and rotor (12) have a trapezoidal or angular cross-section and on the mutually facing sides of the shear rings with interacting cutting edges (25 ) are provided, the teeth can also have a different cross-section, for example a circular, oval, square or rectangular cross-section.
  • the shredder (10) can be understood as a type of turbo-mill, which disintegrates the material to be mixed in the cylindrical container (1), which is arranged with a horizontal longitudinal axis or lying horizontally.
  • the radial openings (18) between the teeth (19 or 24) of the stator (11) and / or rotor (12) preferably have a width between approximately 3 to 10 mm. Such dimensioning ensures safe and gentle disintegration of the mixed materials to be processed. In individual cases, however, the gap widths can also be smaller or larger.
  • the radial arms (22) of the rotor (12) can be designed in an interlaced manner, which brings about a targeted conveying effect in the area of the stator (11) and rotor (12).
  • the gap between the stator (11) and the rotor (12) can be of different widths and widths and is preferably in the range from 1 to 5 mm. A good and satisfactory interaction of the teeth of the rotor and stator is guaranteed in this gap area.
  • stator (11) and the rotor (12) are made of particularly hard material, it being sufficient under certain circumstances to provide the surfaces of the stator and rotor which are particularly subject to wear with a hard material coating.
  • the stator (11) is fastened on two pieces of pipe which are used to add liquid to the area from the outside of the stator (11) and rotor (12) are designed and can be used if the mixture in the container (1) is to be supplied with liquid during processing or is to be moistened in the process.
  • the two pipe sections can be arranged concentrically to one another, so that the liquid can be introduced into the gap between these two pipe sections having different diameters.
  • the shear gap between the stator (11) and the rotor (12) can be designed to be slightly eccentric, that is to say the rotor (12) is arranged or mounted eccentrically in the stator (11). This gives a pulsating disintegration and grinding effect between the two interacting organs (11, 12) of the shredder (10).
  • the shredder (10) which can be referred to as a disintegrating and grinding element or also as a turbo-mill, is preferably arranged in the lateral to lower region of the container (1). It lies in the range from 0 to 180 ° and preferably in a range between 20 and 160 ° to the vertical through the horizontal longitudinal axis of the container (1) or to the horizontally arranged shaft (4) of the mixer located in the container (1).
