Definitions

  • the invention relates to a continuous mixing system, which comprises two special screws that move linearly along their own axes and are also able to rotate about their own axes.
  • the continuous mixers are generally made in three different forms, namely the single-screw mixers, the single-screw mixers with linear movement in the direction of the screw axis, said linear movement being synchronous with a circular movement, and the double-screw mixers.
  • the aforementioned mixers have to be designed differently in order to be able to mix different materials.
  • the reason is that their operating principle is suitable for varying only one or two parameters (number of revolutions, the extent of linear movement in the direction of the screw axis). This reduces the amount of mixing performed per unit time by the mixer and limits the fields where the mixers may be operated.
  • the mixing system according to the invention basically comprises two special screws, which move linearly along their own axes and are also able to rotate about their own axes.
  • Figure - 1 A representative sectional view that shows the linear (forward-backward) movement of the screws in a direction parallel to their own axes, in the system according to the invention.
  • Figure - 2 A representative sectional view that shows the linear (forward-backward) movement of the screws in a direction parallel to their own axes and the rotational movement of the screws about their own axes, in the system according to the invention.
  • FIG. 4 Detailed side view of the screw.
  • the mixing system according to the invention basically comprises two special screws (2), which move linearly along their own axes and are also able to rotate about their own axes.
  • a special drive system moves two screws (2), which rotate at equal speeds and are placed into a sleeve (1) made in a way to suit the purpose, linearly (forward-backward) in a direction parallel to the axes of the screws.
  • Said screws (2) are, at the same time, able to rotate about their own axes, with the rotational movement and the linear (forward-backward) movement of the screws (2) being independent from one another. That is, these movements do not have to be synchronous.
  • Said characteristics of the invention provide the system with the ability of a very high rate of mixing and aiso with a wide field of operation without necessitating a different screw (2) design.
  • the threads (3) on the screws (2) enable the material to advance and to become compressed ( Figure-3), while the profile shaped like a long gear enables a very well mixing for the material.

Abstract

La présente invention concerne un système de malaxage continu caractérisé en ce qu'il comprend deux vis (2) supportant les 5 filets (3) qui permettent au matériau d'avancer et d'être comprimé, lesdites vis (2) étant placées dans un manchon (1) destiné à épouser l'objet, se déplaçant de manière linéaire le long de leurs propres axes et pouvant également se mettre en rotation autour de leurs propres axes.
