Definitions

  • the present invention relates to a mixer for particles and liquids and, more particularly, to a mixer ensuring the uniform coating of all the particles with a binder.
  • mixers of all kinds but not entirely satisfactory when it comes to promoting sufficiently intimate contact with particles of exfoliated rocks, such as vermiculite, and an inorganic or mineral binder, such as an alkali silicate. to ensure the uniform coating of all the grains in order to produce compact decorative panels.
  • the present invention relates to a kneader allowing in particular the impregnation in the mass of the vermiculite by an inorganic binder, characterized in that it comprises a rotary shaft passing through a fixed hopper for supplying particles, carrying a perforated turntable and crossed by a liquid supply conduit terminating in a spray nozzle, a spray chamber into which opens said spray nozzle and a rotary assembly consisting of an agitator placed below the spray chamber and a conical plate.
  • the rotary assembly composed of the agitator and the conical plate is connected by suspension arms to the perforated rotating plate, to rotate with this plate.
  • the conical plate is placed in a mixing chamber provided on its inner wall of at least one counter-blade and which is driven in rotation in the opposite direction to that of said rotary assembly.
  • the arms secured to the perforated turntable extend up to the vicinity of the bottom of the kneading chamber by fingers capable of discharging towards an opening of said bottom, eccentric with respect to the rotating shaft, the particles coated with liquid and deposited on the bottom.
  • the mixer comprises below the perforated turntable a funnel whose opening opening diameter corresponds to that of the part provided with perforations of the perforated tray and whose diameter of the lower outlet opening placed just above the spray chamber corresponds substantially to the diameter of this chamber.
  • the hopper may comprise at its lower part at least one fin which enters a distribution chamber delimited above the perforations of the rotary plate perforated by a wall closed on itself projecting above said perforated plate, so as to oblige particles to pass through the perforations.
  • the upper part of the mixer contained in a housing comprises a drop cone or hopper 1 crossed by a rotary shaft 7, in the axis of which passes a conduit 6 for supplying liquid.
  • the rotary shaft 7 is integral with a perforated plate 3, to which suspension arms 11 are attached.
  • the outer wall of the hopper 1 is provided, at its vertical lower part, with fins 2.
  • the lower end of the conduit 6 is shaped as a spray nozzle 8 placed inside a spray chamber 5.
  • a funnel 4 whose diameter of the inlet 19 corresponds substantially to that of the part provided with perforations 18 of the plate 3, so as to tighten the diameter of the flow leaving the perforations 18 of the plate 3 and reducing it to the dimension of the diameter of the spraying chamber.
  • the outer fins 2 of the hopper 1 preferably enter a particle distribution chamber 21 delimited by a circular wall or closed on itself 22 projecting above the perforated plate 3, so as to stir the deposited particles on this tray and to force them to pass through the perforations 18 to divide into several parallel rotating flow lines, inside the funnel 4.
  • the spraying chamber 5 and the funnel 4 are normally carried by the tray perforated 3, for example using balusters 23, but it would also be possible, in some applications, to have them carried by the conduit 6 reinforced accordingly, so that the funnel 4 and the chamber 5 occupy a fixed position and not rotating in the mixer.
  • an agitator 9 integral with a conical plate 10 forming, with the arms 11, an assembly driven in rotation by the shaft 7.
  • the conical plate 10 plunges into a mixing chamber 12, the bottom 16 of which opens onto a discharge opening 15 which is eccentric relative to the rotary shaft 7.
  • This chamber 12, provided on its inner wall with counter-blades 13, is driven by means of a transmission 17 connected to a motor rotating in the opposite direction to that of the shaft 7.
  • the arms 11 extend to the vicinity of the bottom 16 of the chamber 12 by fingers 14 able to evacuate towards the opening 15 the particles coated with liquid deposited on the bottom 16.
  • the exfoliated vermiculite, or any other granule or particulate material, is introduced into the mixer through the drop cone 1 which regularly disperses it on the rotary plate 3.
  • the passage of the particles through the perforations 18 under the effect of stirring fins 2 increases the vortex movement of the grains already initiated by the rotation of the plate 3.
  • the particle flow is then channeled through the funnel 4 to concentrate on the spraying chamber 5.
  • the liquid binder is brought under pressure into the pipe 6 and sprayed by the nozzle 8 in the heart of the rain of particles and grains swirling inside the spraying chamber 5.
  • the swirling movement imparted to the particles particularly promotes contact between the sprayed liquid binder and the particles.
  • the particles coated with binder are then slightly stirred by the agitator 9 before arriving on the conical plate 10 driven by the arms 11 integral with the plate 3.
  • the particles are distributed pr the tray 10 in the mixing chamber 12 where they are subjected to the action of centrifugal force.
  • the chamber 12 itself rotates in the opposite direction to that of the rotary assembly secured to the shaft 7.
  • the opposite directions of rotation of the suspension arms 11 and of the counter-blades 13 greatly promote the mixing of the coated particles.
  • All the surfaces of the mixer in contact with the particles are preferably coated with a layer of material preventing sticking and residual deposits.
