Definitions

  • the present invention refers to a dosing device of powder or granular.
  • the powder or granular which will be later on named as "material to dose”.
  • the application could be used in industrial and civil applications.
  • the apparatous of the present invention is characterized by a remarkable efficiency and simplicity. It is essentially composed of one or more rotary elements of proper dimensions and shapes, (dipendine on the type of the material to dose) whose velocity of spin confers to the material to dose the necessary centrifuge energy conveyed in one or more calibrated ports placed in suitable distance and position. Such calibrated ports constitute the outled of the dosed material. A proper rotating movement of the rotary elements keep fluid the material to dose contributing, this in order to keep constant and homogeneous the dosage for powders and/or grains, that try to agglomerate.
  • the present invention means to solve, in its intrinsic simplicity, the cases where the present systems of dosage on the market involves high costs, huge dimensions and remarkable difficulties.
  • the rotary element (1) set in action by motor (7), is dipped in the material to dose (3) and derives a centrifuge force to push it through the port of outlet (2).
  • the speed of spin of the rotary element determines in a precise way the amount of material that passes through the calibrated port controlling the flow rate of the dosed material.
  • the rotary element which can be of interchangeable type and with several shapes, is designed according to the physical and fluid-dynamical characteristics of the material to dose.
  • the calibrated port can be of interchangeable fixed areas or shapes or made with a variable geometry. In such a way it can be obtained various ranges of flow rate and the device can be adapted to the various physical and fluid-dynamical characteristics of the material to dose.
  • the dosed material can be directly collected or sent at the outlet of the calibrated port or interfaced to mechanical, hydraulic or pneumatic transport systems.
  • a particular useful application is the interface to a system of pneumatic transport which in case of powder dosage transforms everything into a valid and reliable aerosol generator.
  • the present invention provides us with two types of plants solutions:
  • the dosing device of an independent solution includes the container for the material to dose (see figure 2).
  • the dosing device of immersion system is dipped in a container or pre-existing pipe where it flows the material to dose.
  • the material to dose is expelled outside the container through the action of a transport fluid (see figure 3).
  • the material to dose (3) has been poured in the container (4) and held in motion by an appropriate blade (5) activated by a motor (8) in order to break off some eventual agglomerations.
  • a motor (8) activated by a motor (8) in order to break off some eventual agglomerations.
  • the constant presence of the material to dose is guaranteed by the rotary element (1), activated by the motor (7), and it produces a centrifuge force to expel it from the container through the calibrated port of outlet (2).
  • the regulation of desired flow rate is obtained by varying the speed of the rotary element.
  • the material to dose (3) is found in the container (4) and is held in motion by appropriate blade (5) in order to break off some eventual agglomeration. In this way the constant presence of the material to dose is guaranteed by the rotary element (1), activated by the motor (7), and produces a centrifuge force to expel it from the container through the calibrated port of outlet (2). The dosed material is therefore expelled from the container through the pipeline (6) by a transport fluid.
  • the regulation of the desired flow rate is obtained by varying the speed of the rotary element.
