Definitions

  • the present invention falls within the sector of mixing apparatuses with rotating stirring devices in fixed receptacles, i.e., apparatuses in which the movement of the receptacle is not intended to perform mixing.
  • this mixer also falls within those mixers that have stirrers with planetary movement, i.e., that rotate around their own axis and around a vertical axis.
  • the object of the invention is a mixer of the type that has a conical container in which an endless screw moves arranged close to and parallel to the inner wall of the container and rotates on its own axis and around the vertical axis of the mixing container.
  • the endless screw began to be placed with the lower end thereof at the centre and with the upper end thereof eccentrically in the mixing receptacle, so that said screw is located at all times near the side wall of the conical container, while being provided with drag means so that said screw rotates on its own axis and around the vertical axis of the mixing container.
  • this endless screw is actuated by means of one or more motors located above the container, which move a central vertical axis coinciding with the vertical axis of the container, in which it couples a transmission that in turn is coupled at the upper end of said endless screw, enabling both movement around the container and rotation around its axis, which generates the vertical flow of the product in order to make the mixture homogeneous.
  • mixers of this type particularly when they have a very large rotation radius, is that the rotating arm is not very stable in its perimeter rotation due to the displaced loads, which causes oscillations during the rotation thereof and friction of the endless screw with the wall of the container, particularly when the endless screw works without support on the lower portion of the container.
  • an aim of the present invention is to prevent the aforementioned drawbacks of the known mixers and achieve a mixing device that is very simple to construct, efficient to use and enables complete mixing to obtain a finished product of great homogeneity and practically without losses.
  • Another aim of the invention is to prevent the endless screw from oscillating in the lower portion thereof, which will contribute to increasing the useful life of the mixer and reducing noise and friction on the wall of the container.
  • the invention proposes a conical mixer, having the features of claim 1.
  • the conical mixer of the invention includes a horizontal ring, which is located along the perimeter inside the conical container, above the lid thereof.
  • This perimeter ring constitutes a support means for supporting at least one bearing that is fixed at the end of a horizontal arm that rotates on an axis coinciding with that of the container and that also includes at the end a transmission for actuating the endless screw during rotation.
  • Another feature of this mixer is the fixing of the perimeter ring, which is fixed above the lid of the mixer, attached by means of adjustable bolts thereto.
  • the bearing(s) on which the end of the rotating horizontal arm rests on the perimeter ring are mounted angularly, so that they are located in a substantially horizontal plane on said perimeter ring, despite the fact that the transmission from the horizontal axis to the inclined endless screw to be located close to the inner periphery of the conical container is located inclined at an angle equivalent to the conicity of said container.
  • These bearings are also mounted with the interposition of one or more pretensioning washers that enable the position of the bearings on the perimeter ring to be adjusted in order to fully support it.
  • the invention relates to a conical mixer of the type that is made up of a conical mixing container (1), which has a lower outlet mouth for the mixed product and is internally provided with an endless screw (2), arranged with the lower end thereof at the centre of the container (1) and with the upper end thereof eccentrically in said container, so that said endless screw (2) is located at all times near the side wall of the conical container (1).
  • This endless screw (2) is actuated by a motor-reducer (3), located on the lid (9) of the container, which moves a vertical axis (4) located in correspondence with the axis of the conical container (1).
  • Said axis (4) provides a rotational movement to a horizontal arm (6) that includes at the free end thereof, close to the inner wall of the container (1), a transmission (5) to also actuate the endless screw (2) during rotation, while said arm (6) rotates around the axis (4); in this way a vertical flow is generated in the product to mix it homogeneously.
  • a horizontal ring (8) is located along the perimeter inside the container (1).
  • the end of the horizontal arm (6) is supported on bearings (7), which have been represented in greater detail in Figs. 4-6 .
  • the bearings (7) are mounted on a plate (10) that is screwed on top of the transmission (5) located at the end of the horizontal arm (6). Since the transmission (5) that promotes the movement of the endless screw (2) must form an acute angle with the horizontal arm (6) so that the endless screw is inclined and parallel to the inner edge of the container (1), it has been provided that said bearings (7) are placed angularly with respect to the plate (10) so that they are located in a substantially horizontal plane on the perimeter ring (8) (see Fig. 5 ).
  • the bearings (7) on which the end of the arm (6) rests on the perimeter ring (8) are mounted with at least one pretensioning washer (11) in order to slightly lengthen or shorten the position of said bearings (7) with respect to the base plate (10), in order to adjust the support of the bearing so that it is completely on the perimeter ring (8).
