Definitions

  • the present invention is related to a blade for a 5 mixing device, according to the preamble of the claims.
  • Mixing devices of this kind are used within a number of fields for mixing two or more different substances of particles or liquids or a combination of such, to a desired degree of homogeneousness.
  • the different substances are supplied in amounts 0 which are metered to a specified degree.
  • Such substances may be tow or more liquids to be mixed, two or more particles or particles to be added and mixed with liquids.
  • the substances to be mixed have greater or smaller differences in nature and condition.
  • Such mixing devices also are used for drying or freezing particles, set out as separate processes or as part of a mixing process.
  • Mixing devices of the above mentioned type normally operate with blades or shovels secured to two parallel rotors, o rotating in opposite direction.
  • the shape and the arrangement of the blades causes the masses to be thrown up thereby to be mixed and simultaneously transported forwards in the mixing device. It here certainly is important that the so-called casting curvatures is optimized, thereby to achieve the best possible mixing 5 simultaneously with the desired forward transportation.
  • figure 1 discloses schematically a mixing device having two rotors, in an axial view, figure 2 discloses a side view towards the rotor axis of one blade form and figure 3 discloses a corresponding view of a modified blade form.
  • a blade 1 for example as part of a circular s pipe
  • such pipe conveniently may be divided into four segments, each corresponding to 90° and where each segment is secured to the rotor as disclosed in figure 2, turned an angle a in relation to the rotor axis.
  • the angle ⁇ suitably may be 20° which means that part of the masses are influenced by the front part 3 of the o blade and one part is influenced of the rear part 4.
  • the curved form of the blade provides a substantial dispersal of the masses being thrown up and partly also a transportation backwards in relation to the transportation direction of the mixing device, namely of the masses which are influenced of the rear part 4.
  • the outer circumference of the blade suitably is bent up to a flange 2 or a flange 2 is secured to the blade, as a continuous curvature or as a obtuse angle to the blade.

Abstract

La présente invention concerne une pale destinée à un dispositif mélangeur, notamment un appareil mélangeant différentes particules ou différents liquides, laquelle pale se monte sur des rotors sensiblement horizontaux. Chaque pale est caractérisée par une première face présentant une incurvation orientée dans le sens de déplacement des particules. Dans le sens radial, la forme des pales présente des lignes droites disposées perpendiculairement à l'axe du rotor. La pale incurvée est constituée d'une première partie (3) orientée dans le sens de déplacement des masses, d'une deuxième partie (4) sensiblement plus petite, orientée dans le sens inverse du déplacement, et d'une partie intermédiaire reliant les deux premières parties précitées et disposée sensiblement parallèlement à l'axe du rotor. Cette structure permet de propulser, d'une part vers l'avant une partie substantielle de masses, tandis qu'une moindre partie subit une centrifugation, et d'autre part vers l'arrière, les particules venant ainsi se mélanger aux particules propulsées vers l'avant à partir de la pale suivante.
