Definitions

  • the present invention relates to a process for preparing a mixture composed of mineral fibers and hydraulic and organic binders in particles or liquids.
  • Such mixtures generally composed of slag wool or volcanic rock wool, cement and silicate particles and oil are generally intended to be applied, after addition of water, by spraying onto a surface to achieve a coating with insulation, thermal and acoustic properties and fire resistance.
  • the present invention aims to remedy the drawbacks of the state of the art and firstly proposes a process for the preparation of a mixture composed of mineral fibers and hydraulic and inorganic binders in particles or liquids consisting of defibrating in coitinu a bale of fibers, to continuously transport the fibers to the inlet of a screw conveyor-mixer, to continuously add, during their journey, the binders to the fibers and to evacuate at the outlet of the screw conveyor-mixer mixture obtained.
  • the method according to the present invention also consists in incorporating into the fibers, as they travel, for example cement and silicate.
  • the method according to the present invention also consists in incorporating into the fibers, during their passage in the screw mixer conveyor, for example oil.
  • the present invention also relates to a device for the preparation of a mixture composed of mineral fibers and hydraulic and inorganic iants in particles or liquids. for the implementation of the above process.
  • This device comprises means for supporting at least one bale of fibers, means for continuously defibrating this bale, means for continuously transporting the fibers up to the entrance of a screw conveyor-mixer, means to continuously add to the fibers, during their passage, the binders and means for evacuating the mixture obtained, at the outlet of the screw conveyor-mixer.
  • said means for supporting the bale of fibers are preferably formed by a conveyor belt, the means for defibrating this bale being formed by at least one tooth roller towards which said conveyor belt moves the bale of fibers .
  • said means for transporting said fibers to the inlet of the screw conveyor-mixer preferably comprises at least one belt conveyor.
  • said means for adding the particle binders preferably comprises a reservoir for the binder and a screw conveyor for continuously bringing and discharging this binder on the path of the fibers.
  • a series of nozzles making it possible to spray oil on the fibers in the screw-mixing conveyor can be provided.
  • the device shown in the figures and identified; generally by the reference 1 comprises a horizontal conveyor belt. 2 on which there is a ball 3 of mineral fibers such as slag wool or volcanic rock wool and two horizontal rollers 4 and 5 placed one above the other. Rollers 4 and 5 are provided at their periphery 6th teeth which allow the ball 3 to be defibrated regularly and continuously when the latter is moved by the horizontal conveyor 5 in their direction.
  • a ball 3 of mineral fibers such as slag wool or volcanic rock wool
  • rollers 4 and 5 are provided at their periphery 6th teeth which allow the ball 3 to be defibrated regularly and continuously when the latter is moved by the horizontal conveyor 5 in their direction.
  • the fibers coming continuously from the bale 3 are discharged onto a belt conveyor 6 which continuously feeds the fibers onto the lower part of an inclined belt conveyor 7.
  • a tank of particulate cement 8 and a tank of particulate silicate 9 which are provided at their base with screws 10 and 11 for transport and metering, the outlet conduits 12 and 13 of which open above the conveyor belt 7 so as to pour a metered quantity of cement and silicate there.
  • the belt conveyor 7 continuously pours the fibers, the cement and the silicate which have been added to it into an inlet hopper 14 of a screw mixer-mixer 15 arranged horizontally.
  • the screw conveyor-mixer 15 comprises two parallel screws 16 and 17.
  • a conduit 18 provided with a series of nozzles 19 oriented in the direction of the space between the screws 16 and 17.
  • This conduit 18 is intended for spraying oil from a reservoir 20, by a pump 21.
  • the screw conveyor-mixer 15 has two conduits 22 and 23 oriented downwards, these conduits 22 and 23 making it possible to pour the mixture obtained for example into bags. On these conduits 22 and 23 can also be provided dust suction means, these means have not been shown.
  • FIG. 2 It can be seen in FIG. 2 that a large tank 24 for cement has also been provided, an elevating screw 25 allowing the cement to be brought continuously from the base of the tank 24 to the cement tank 8.
  • the device 1 shown in the figures and described above makes it possible to continuously obtain or prepare the desired mixture. Indeed, by adjusting the speed of movement of the conveyor 2 and the speed of rotation of the defibrating rollers 4 and 5, by adjusting the speed of rotation of the transport and metering screws 10 and 11, it brings to the end of the input 14 of the screw mixer-conveyor 15, via the belt conveyors 6 and 7, the quantity of fibers desired, the quantity of cement desired and the quantity of silicate desired. By adjusting the pump 21, the desired quantity of oil is sprayed, via the nozzles 19. It is understood that the length of the screw conveyor-mixer 15 is adapted to obtain at its outputs 22 and 23 a substantially homogeneous mixture, the quantities mentioned above taking account of the length of the screw conveyor-mixer 15.
  • the various elements constituting the device 1 are carried by posts and that the belt conveyor 7 is over a large part of its length surrounded by a fairing 26.
  • the lower part of the conveyor belt 7, the conveyor belt 6 and the assembly formed by the conveyor belt 2 and the defibrating rollers 4 and 5 could also be surrounded by a fairing.
