Definitions

  • the invention relates to a rotating bowl mixer. More particularly, the invention relates to a conical mixer with screw and rotating tank. Such a mixer is intended for mixing powdery or granular dry products, possibly incorporating liquid for humidification or the formation of paste.
  • This orbital movement is obtained by a central or lateral motorization (single or double) and allows, on the one hand, a displacement in rotation of the Archimedes screw around the axis of the tank along the internal circumference of the conical tank positioning the screw successively tangentially to each generator of the cone, and on the other hand, an axial rotation of the screw on itself making it possible to move the powdered product from bottom to top and thus to achieve mixing.
  • a first drive device makes it possible to obtain a slow rotational movement around the axis of the conical tank;
  • a second drive device allows, generally by means of a bevel gear transmission located in the support arm of the screw, to obtain the axial rotation of the turn on itself.
  • the Archimedes screw is carried by a cover rotatably mounted along the axis of the conical tank.
  • a first motor drives the cover in rotation around the axis of the tank, a second motor carried by the cover rotates the screw along its axis.
  • a first object of the present invention is to provide a mixer which overcomes the drawbacks or limits of those known from the prior art.
  • Another object of the present invention is to provide a mixer whose mechanical drive characteristics are simple, and therefore reliable.
  • Another object of the present invention is to provide a mixer in which a combination of different rotational movements can be provided at low cost producing a multidirectional effect applied to the entire moving mass, thus allowing very good homogenization and perfect dispersion of product particles.
  • the connecting element comprises a ball ring fixed on the tank in a plane generally perpendicular to the axis of the tank, carried by a path horizontal bearing integral with the chassis and on which come to wear balls of the ball crown.
  • the rotational drive means may comprise a toothed ring secured to the conical tank, and a second element secured to the chassis and driven in rotation.
  • the ring gear can advantageously be a ring gear with balls, acting both as a connecting element and as a means for driving in rotation.
  • the invention also relates to a mixer comprising in combination the aforementioned characteristics and described below.
  • FIG. 1 represents a conical mixer with an Archimedes screw and a rotating tank. Such a mixer is intended for mixing dry powdered or granulated products, with the option of incorporating liquid for humidification or the formation of paste.
  • the mixer comprises a conical tank 1 provided in its upper part with a cover 2 and having at its lower part a drain flap 3.
  • the cover 2 is provided with a certain number of orifices intended for example to allow the supply from the tank of products to be mixed, to the passage of a sprinkler pump, to the passage of one or more mixing screws, to the passage of one or more special tools intended to improve the dispersion and homogenization of the mass to mix etc.
  • Figure 1 a single mixing screw 4, driven in axial rotation by a first gear motor 5, and oriented tangentially to a generator of the conical tank wall 1 so as to remain permanently close to the internal face of the tank.
  • the mixer according to the invention comprises at least a first mixing screw 4 and a second mixing screw 104.
  • the first mixing screw 4, driven in axial rotation is oriented tangentially to a generator of the vessel wall 1 to remain permanently close to the interior face of vessel 1, and may have a turn thread having a pitch, that is to say the distance separating two consecutive turns, variable.
  • the thread of the turn of the first mixing screw 4 has a number of steps of dimension x and a number of steps of dimension y with x greater than y.
  • the second mixing screw 104 may include a turn thread having the same configuration, except that the steps of dimension x of the first mixing screw 4 are opposite the steps of dimension y of the second mixing screw 104 and reciprocally.
  • the difference in speed of movement of the pulverulent product caused by the differences in size of the steps of the turns makes it possible to obtain in the product disordered and multidirectional movements which accelerate and improve the speed and the quality of the mixture.
  • the second mixing screw 104 driven in axial rotation, is oriented obliquely and further away from the tank wall 1, placed at the heart, to stir the central part of the product to be mixed.
  • a lump-disperser tool 204 is also provided, consisting of a motor driving a propeller shaft oriented vertically along the vertical axis 20 of the tank 1.
  • the mixer according to the invention comprises a first assembly kept fixed relative to a vertical axis 20 and a second assembly provided with a rotational movement relative to the same vertical axis 20.
  • the first assembly is held fixed by attachment to a frame 6 associated with a support 7 of the mixer.
  • This first assembly comprises the cover 2 of the tank 1 on which the mixing tools are fixed such as the first mixing screw 4, the second mixing screw 104, the lump-disperser tool 204.
  • the first mixing screw 4 is fixed on the cover 2 so that its axis of rotation 18 is parallel to the wall of the conical tank 1 and that the free end of its turn is flush with the drain flap 3.
  • This characteristic is possible due to the use, in the mixer of the invention, a guillotine valve 14 with manual or mechanized control as a means of closing the discharge hatch 3.
  • This guillotine valve 14 is fixed on the support 7 of the mixer.
  • a ball valve can also be used.
  • sealing means constituted in particular by a seal 19 inserted between the body 21 of knife gate valve 14 and a rotating flange 15.
  • the rotating flange 15 is integral with the tank 1, and carries vertically the central part 24 of the valve body 21 by allowing the relative rotation between the rotating flange 15 and the valve body 21 by means of a ring 22 of non-stick material such as polytetrafluoroethylene, in the embodiment of FIG. 3, or of a ball ring 23 in the embodiment of FIG. 4.
  • the valve body 21 is locked in rotation by the support 7 of the mixer, to which it is fixed by its offset part 25.
  • the cover 2 of the conical tank 1 and the frame 6 are in one piece but it should be understood that such an embodiment can be replaced by another, as long as the cover 2 is kept fixed relative to to the vertical axis 20.
  • the second assembly driven in a rotational movement relative to the vertical axis 20 comprises in particular the conical tank 1.
  • the rotation of the tank 1 is obtained by a first element 8 secured to the conical tank 1 and movable relative to the chassis 6, a second element 9 which is integral with the chassis 6 and which is driven in rotation, and finally a connecting element 10 interposed between the tank 1 and the chassis 6.
  • the connecting element 10 is adapted to carry the tank 1 and authorize its rotation along its axis 20.
  • the connecting element 10 comprises the first element 8 and elements 10a and 10b.
  • the first element 8 is a toothed ring crown which is fixed on the tank 1 along a plane generally perpendicular to the axis 20 of the tank 1.
  • This toothed ring 8 constitutes the movable frame of a ball bearing and is worn by a horizontal track 10b secured to the chassis 6 constituting the fixed frame of the bearing and on which the balls 10a of the toothed crown with balls 8 roll.
  • Such a connecting element 10 with a toothed ring crown 8 will be used especially in small capacity mixers.
  • the ball ring 8 may be replaced by a raceway with guidance by several bearings to ensure guiding in rotation and recovery of the vertical load.
  • the second element 9, which comes in reciprocal cooperation with the ring gear 8, comprises at least one toothed wheel and / or at least one pinion having an axis of rotation 16 parallel to the axis 20 of the tank 1.
  • This second element 9 consisting of a gear system, is rotated by a second geared motor 11 fixed to the frame 6 or the support 7 of the mixer.
  • the gear system can be of helical, cylindrical, conical or equivalent type.
  • rotational drive can be provided by sprockets, wheels and chains.
  • a seal 13 disposed along the upper circumference of the conical tank 1.
