Definitions

  • the invention relates to a ring trough positive mixer with a mixer rotor, which is driven from below via a drive shaft guided through an interior of the ring trough and a drive motor and has at least one mixing tool engaging in the ring trough, at least one of the mixing tools being rotatable and by which Drive shaft can be driven via a gear transmission.
  • DE-U-19 67 024 describes a mixer whose mixer rotor is driven from below via a drive shaft which is arranged in the interior of the ring trough.
  • the drive shaft is connected to a drive motor via a gear, the gear housing forming the inner wall of the ring trough.
  • a gearwheel of a gearwheel gearbox is provided at the upper end of the gearbox housing, by means of which at least one of the mixing tools can be driven.
  • the gearwheel mentioned is located in the upper region of the annular mixing space, that is to say outside the interior mentioned.
  • the height of the mixing chamber is thus reduced by the gearwheel or the gearwheel transmission, or the overall height of the mixer must be increased accordingly in order to obtain a certain height for the mixing chamber.
  • a housing accommodating the gear mentioned is required in order to avoid contamination or even damage to the gear by the mix.
  • a seal assembly is required for the housing to prevent oil or other lubricant from the gear train from reaching the mix in the ring trough.
  • a mixing machine for building materials is known from DE-B-11 25 337, in which the gear is arranged below the ring trough.
  • the drive shaft arranged in the interior of the ring trough projects downwards into the gearbox.
  • the mixing tools are arranged essentially rigidly on the rotor and these mixing tools are not driven to move relative to the rotor.
  • the inner wall of the trough is formed by a piece of pipe and a spacer sleeve and the rotor contains a cup-shaped tool carrier which forms a labyrith seal with the piece of pipe.
  • the invention has for its object to further develop the ring trough compulsory mixer of the type mentioned above in such a way that the interior of the ring trough is used for the gear transmission and a low overall height is achieved.
  • a trough inner wall is provided, which extends to the underside of the rotor, that there is a space between the gear housing and the inner trough wall and the underside, in which space the ring gear and the gear for the mixing tool are arranged.
  • the ring trough compulsory mixer designed in this way is distinguished by a comparatively small overall height, since the ring gear of the gear transmission is arranged in the space mentioned and not in the ring trough. This results in an optimal utilization of the construction volume, whereby a not inconsiderable saving in weight and material is also achieved.
  • a high filling level for the mix can be permitted.
  • said toothed ring is protected against contamination in a particularly simple manner.
  • the gear mechanism for driving the mixing tool can contain additional gear wheels or a belt or chain drive in addition to the ring gear arranged in the space in the interior, in order to be able to drive several mixing tools if necessary.
  • the rotor can have several fixed and also several rotatable mixing tools.
  • FIG. 1 schematically shows an axial longitudinal section in which a ring trough 2 and a rotor 6 rotatably arranged about a first axis can be seen.
  • the ring trough 2 with its cover 8, like an electric drive motor 10, belongs to the base frame 12.
  • the electric drive motor 10 is connected via a propeller shaft 14 to a transmission, the transmission housing 16 of which is shown.
  • the gear housing 16 is inserted into the interior of the ring trough 2, there being an intermediate space 18 which is formed by the inner wall of the trough, the gear housing 16 and the underside of the rotor 6. If necessary, the drive motor 10 is also flanged directly to the transmission.
  • the transmission has a drive shaft 20, the upper shaft journal is indicated here with dashed lines.
  • the rotor 6 is rotatably mounted in a manner not to be explained in more detail here, the transmission of the rotary movement to the rotor 6 being carried out by means of the drive shaft 20.
  • the rotor 6 has a number of mixing tools 22 which are essentially fixedly connected to it, each of which contains an elastically or rigidly mounted mixing arm 24 and a mixing blade 26.
  • the mixing blades 26 protrude into the ring trough 2 or into the mixture 28 located there and indicated by the dash-dotted line. When the rotor 6 rotates, the mixing blades 26 rotate with the rotor 6.
  • a rotatable mixing tool 30 is connected to the rotor, but this about an axis 32 with respect to the rotor 6 so that the rotatable mixing tool can basically have one or more mixing blades.
  • the rotating mixing tool performs a rotation in the opposite direction to the rotor rotation.
  • the mixing tools may also have a different structure or shape.
  • all of the mixing tools can optionally also be arranged rotatable about separate axes of rotation with respect to the rotor, but at least one mixing tool must be fixed for the purpose of emptying the ring trough.
  • the emptying can be carried out in a particularly simple manner, since, as already explained, the mixing tools 22 are arranged on the rotor essentially in a rotationally fixed manner.
  • An emptying device 40 is provided below the ring trough 2 in order to open or close off an opening located in the bottom of the ring trough 2 by means of a slide.
  • a total of ten essentially fixed mixing tools 22 are connected to the rotor 6. These mixing tools 22 are arranged in a known manner on mixing arms of different lengths and also at different heights with respect to the axis of rotation in order to obtain good mixing of the mixing material in the ring trough 2.
  • the rotor 6 is provided with a lateral extension 42, on which the rotatable mixing tool 30 is arranged. The rotational movement of the rotor 6 is indicated by the arrow 46.
  • the mixing tool 30 also performs a rotational movement in the direction of arrow 44, the latter rotational movement being superimposed on the rotation of the rotor in the direction of arrow 46.
  • the mixing tool 30 is preferably rotated in the opposite direction to the rotation of the rotor 6.
  • the mixing blades 36, 38 are rotated in the opposite direction.
  • the mixture 28 is separated and a particularly good mixing takes place.
  • a particularly fast and intensive mixing of the mix in the ring trough 2 is thus achieved, for which only an extremely small additional effort is required.
  • An emptying opening 48 is represented by the approximately semicircular line. The emptying opening 48 is covered during the mixing by means of a slide 50 which can be actuated by the emptying device 40 explained above for the purpose of emptying.
  • Fig. 3 shows an enlarged partial section, in which the gear housing 16 has an approximately conical shape.
  • a ring gear 52 is flanged, which has an internal toothing 54.
  • the ring gear 52 can also be flanged to a separate receiving device.
  • a gear 66 is provided in the interior 56 of the rotor 6, which is connected to the ring gear 52 via a gear 60, so that the rotatable mixing tool 30 can be driven via the gear gear 58 designed in this way.
  • the ring gear 52 is located in the intermediate space 18, which is surrounded by the inner wall 68, the gear housing 16 and the underside 70 of the rotor 6.
  • the mixing tool 30 is arranged on the rotor 6 by means of a mounting and bearing device 62.
  • This device contains a shaft 64, at the lower end of which the rotatable mixing tool 30 and at the upper end of which the gear 66 is located inside the rotor 6.
  • the rotor 6 is rotatably connected to the upper pin of the drive shaft 20 by means of a feather key.
  • the rotor 6 is also rotated by rotation of the drive shaft 20. It can be seen that due to the toothed ring 52 firmly connected to the gear housing 16 and also via the gear 58, the mixing tool 30 also undergoes a self-rotation about the axis 32.
  • a sealing arrangement 72 is located between the upper edge of the inner wall 68 of the ring trough 2 and the underside 70 of the rotor 6.
  • This sealing arrangement 72 has two rings 74, 76 which are arranged coaxially to the drive shaft 20 and are fixedly connected to the underside 70 of the rotor 6 surround the upper part of the inner wall 68.
  • a labyrinth seal is thus created in a particularly simple manner in order to largely prevent the penetration of dust or other dirt from the ring trough into the space 18. In this way, the reliability and operational safety are not negligibly improved.
  • the ring trough 2 is provided with a lining 78 in a known manner. There is also an annular gap between the upper end of the lining 78 and the ring 74, through which the sealing effect is thus increased in a particularly simple manner.
  • the ring 76 is designed as a sealing ring with sealing lips or the like. With such a sealing ring achieved a reliable seal, either alone or in cooperation with the labyrinth seal explained above.
