Definitions

  • the invention relates to a homogenizer apparatus for dispersing and / or homogenizing flowable substances, with a container having one or more inlet opening for introducing the substances to be homogenized, in a central region of its bottom a container outlet opening for supplying the substances in a below the Bodens arranged processing unit having two independently rotatably mounted, concentrically arranged circularly formed sprockets, which are separated by a predetermined gap, wherein a first sprocket and a second sprocket in the processing unit are arranged on a respective shaft perpendicular to Is arranged central axis of the container for substances to be homogenized, wherein the sprockets as part of a compact Machining unit are formed, which is arranged immediately below the bottom of the container.
  • a device of the type mentioned is out FR-A-2 364 289 known.
  • the object of the invention is to provide a homogenizer device with a compact processing unit that works effectively and yet allows an adaptable to a given substance mixture processing.
  • this object is achieved in that the distance between the sprockets via at least one displaceably mounted shaft is adjustable.
  • the distance between the sprockets via at least one displaceably mounted shaft is adjustable, that all components of the processing unit can be attached very close below the bottom of the container, and thus to be homogenized substances over a comparison to the prior art shorter supply line can be introduced into the processing unit and are also attributable to a shorter compared to the prior art return line into the container.
  • a processing of very small amounts of substance is possible in particular.
  • the construction according to the invention allows a direct flanging of a drive motor on a drive shaft while avoiding gears, belts or the like. This has the consequence of a reduction of components, manufacturing costs and maintenance costs. Furthermore, will due to the direct coupling of the drive motor with the drive shaft reduces the formation of unwanted vibrations and thus increases the smoothness and the synchronization of shafts and rotors.
  • Another advantage of the device according to the invention is the lower height to call in comparison to a conventional device in which the drive shafts of a first sprocket and a second sprocket of the processing unit are arranged axially in the conveying direction of the outlet opening leaving substances.
  • a mixing conveyor wing having a plurality of leaf elements for mixing the substances to be homogenized with at least one powdery substance and for deflecting the conveying path of the substance mixture by 90 ° in the direction of the decentered to the vertical axis container arranged processing unit is provided, wherein the axis of rotation of the Misch department pursuels is also perpendicular to the conveying direction of the outlet opening leaving substances.
  • liquid is divided from the container after emerging from an outlet opening of the container by means of the mixing conveyor wing in discrete liquid thrusts, which successively behind the mixing conveyor wing to move in the direction of the homogenization unit.
  • the liquid is supplied with powder and possibly another liquid or powdery substance.
  • the powder and the optional further substance mix more intensely with the liquid particles of the thrombus in a peripheral region of a thrombus than in a central region of the fluid thrombus, since the liquid particles have a higher kinetic energy in the peripheral region.
  • liquid thrombus contains more liquid mass in its peripheral region than in its central region, so that it can easily lead to clumping of the powder supplied in its central region, since on the one hand only a small amount of liquid particles are present and on the other hand, the kinetic energy of this Liquid particle is so small that it is sometimes not sufficient to dissolve powder clusters.
  • the powder clusters thus formed in a central region of a liquid thrombus may, in a subsequent processing operation in a homogenization unit, lead to blockages in the region of the respective rotors.
  • the thrombi resulting from the vertical shaft bearing of the mixing conveyor blade would have a pressure due to the velocity distribution of the particles of the peripheral region due to the centrifugal force Direction effect on the inner wall of the delivery line, ie against the conveying direction of the supplied through the inlet supports powder substances.
  • the feeding of powder would be hindered.
  • this disadvantage does not occur due to the avoidance of thrombus formation, because a supply of powder substances is not impaired by an internal velocity and morphology profile of a thrombus. Instead, an improved mixing of the substances in question takes place largely without trombe formation.
  • the sprockets arranged perpendicular to the central axis of the container are preferably each driven by a shaft arranged horizontally in the processing unit.
  • the second sprocket is slidably mounted in the direction of its central axis such that it can be transferred from a first position in which it is arranged radially behind the first sprocket in a second position, in he is outside the conveying path of the funded from the first sprocket flowable substance is arranged.
  • the substances can be returned to the container after being processed by the sprockets into a container inlet opening in the region of the container bottom.
  • the container inlet opening is preferably provided in a central region of the container bottom.
  • the substances after processing by the sprockets also be attributable to a container inlet opening in the region of the container wall in the container.
  • the substances are preferably conducted from a central region through the intermediate space into a peripheral region of the toothed rings.
  • the shafts of the sprockets are preferably drivable by separate drive units and can be operated in particular preferably in synchronism or in the opposite direction.
  • the sprockets are coaxially conical.
  • At least one of the shafts of the device according to the invention may optionally but not necessarily be designed as a hollow shaft through which a further substance can be introduced into the processing unit.
  • a conveying vane-having inducer which is arranged upstream of the sprockets, is preferably provided in the processing unit.
  • the inducer acts as a means to promote the substances to be homogenized under a controllable pressure in the direction of the sprockets.
  • the inducer acts as a pump device for the effective conveying of the substances to be homogenized.
  • the mixing conveyor blade is provided in the processing unit, which is also arranged upstream of the sprockets.
  • the Mischfördeeriel fulfills the task of mixing powder or liquids of the substance to be homogenized in premixed form and to prevent blended Good is sucked into the container due to a possibly prevailing in the container negative pressure. This has the advantage that the additional substances can be supplied in a very precisely dosed manner, with the formation of agglomerates being prevented by way of thorough mixing.
  • the Misch cognitive selfishl is formed substantially like a conventional propeller with low-set blade elements, wherein a blade member is arranged inclined at an angle of about 5 ° to 10 ° with respect to a plane of rotation.
  • a leaf element preferably covers an angular range of about 30 ° to 70 °, in particular 50 °.
  • two leaf elements are arranged in mutually different planes of rotation.
  • the processing unit 120 includes two independently rotatably mounted, concentrically arranged, circular-shaped sprockets 130, 140, which are separated by a predetermined gap, wherein a first sprocket 130 and a second sprocket 140 in the processing unit 120 on each of a shaft 131, 141 are arranged, which is arranged perpendicular to the central axis of the container 110 for substances to be homogenized.
  • the sprockets 130, 140 are part of the formed compact processing unit 120 which is disposed immediately below the bottom of the container 110.
