Definitions

  • the invention relates to a method and a device for merging and mixing or dissolving liquid, solid and gaseous substances in which the venturi principle is realized by means of a variable cross-sectional constriction.
  • the inventive method allows in particular the high-precision, pressure-independent control of the supply of substances and the avoidance of special control devices in the Zugarwegen the materials to be supplied.
  • a disadvantage of this method and the device is that caused by the constriction with a ball valve turbulence and disturbances of flow, which do not allow a controlled pressure curve in the narrowed area and impede the subsequent supply of materials in the expansion area in the steady flow by vortex. As a result, an exact supply and dosage without further rule installations is impossible.
  • a disadvantage of this method is that the cross-sectional constriction can be made due to the execution only in a narrow control range which only allows a small power range. Different flow pressures also influence the control behavior. Because the supply of the one Substance takes place centrally in the flow of the second substance, it does not come here to ideal mixing and hinders a subsequent rapid solution of the substances.
  • the structure of the device is costly due to the complexity of the design.
  • the embodiment can not be used for hygienic purposes, especially for the food and pharmaceutical industries. A dead space-free cleaning is not possible. More than 2 substances can not be introduced simultaneously.
  • Another disadvantage is that the 2nd fabric is supplied at the circumference of the control needle and thus not in the optimal cross-sectional constriction. The Venturi effect is therefore not finely adjustable. With a considerable narrowing of the cross section of the back pressure increases without the second fabric can be sucked by a venturi effect. A subsequent turbulence for mixing and solution of the substances is not given.
  • the method and the device according to the invention avoid these disadvantages in which one or more streams, which may also be mixtures of other materials, enter a housing, one or more built-in parts narrow the cross section of this pipe in the axial direction and the material supply in the region or the Constrictions or immediately after the narrowing (s). Furthermore, a desired turbulence, based on the flow from outside to inside, bring about a high mixing and solution of the substances, without the supply of these substances being disturbed.
  • the stroke of this component is variable.
  • the stroke can be varied over a wide range via a continuously regulating stroke adjustment or a non-continuously regulating stroke adjustment and adapted to the desired result.
  • Embodiment here is the continuous control by means of a positioner which is controlled by a setpoint / actual value comparison of the feed stream, the desired exit parameter or the desired control target
  • FIG. 1 An embodiment with a main flow (1.1), a housing with positioner (1.2) and a control of the feed stream (1.3) (measurement 2) or the quality of the total current (1.4) (result measurement) is shown in Figure 1.
  • the cross-sectional constriction can be maintained consistently. Large volume flow areas are possible due to the variable cross-sectional constriction without disturbing the flow and the pressure curve in the constriction by separation vortices in this constriction.
  • a defined detachment and turbulence of the assembled substances after the narrowed cross-section may be due to the variable shape of the cone or cone with intentionally different heights
  • the vertebrae do not interfere with the steady supply since the demolition vortices of the main flow lead from the outside to the inside and not from the inside to the outside.
  • this method allows the delivery of substances across different interfaces, e.g. Sintered inserts, membrane inserts, bores, with different passage rates. Due to the method according to the invention, an aseptic or hygienic design, which can be cleaned and sterilized without a dead space, can take place. The simplicity of the possible embodiments allows a cost-effective production.
