Definitions

  • the invention relates to a process for the preparation, transfer and continuous application of a homogeneous and slightly aerated fluid aqueous suspension containing powdery mineral materials, at least one hydraulic binder and possibly other known constituents, intended for the field of building and public works, in particular the leveling of surfaces.
  • the invention also relates to a device for the preparation, transfer and continuous application of a fluid, homogeneous and weakly aerated aqueous suspension containing powdery mineral materials, at least one hydraulic binder and possibly other known constituents used. works in the field of building and public works.
  • fluid aqueous suspensions from dry powdery mineral materials, which can have up to approximately micrometric dimensions, associated with at least one hydraulic binder and with possible other known constituents, can only be carried out through devices adapted to this type of treatment, and not through already existing devices for other applications, arranged by a simple transposition of means.
  • This preparation must be done by the homogeneous dispersion of a pulverulent solid phase in a liquid phase which is water, by automatic mixing.
  • the solid pulverulent phase of the aqueous suspension to be prepared is formed, in the majority of cases, of dry materials to be mixed or already premixed, which are, for example, mineral fillers, sands, mortars and / or cements, plasters , materials used in finishing plasters, or even in smoothing fluids intended to smooth surfaces in the building sector.
  • dry materials to be mixed or already premixed which are, for example, mineral fillers, sands, mortars and / or cements, plasters , materials used in finishing plasters, or even in smoothing fluids intended to smooth surfaces in the building sector.
  • the rotation of the "pigtail” screw in the female casing allows the continuous transfer by discharge of said aqueous mineral suspension, through a flexible tube connected to the pump.
  • this type of device is causing annoying disadvantages for the user which make its operation incompletely satisfactory for the preparation, transfer and application of fluid, homogeneous and poorly aerated aqueous mineral suspensions. .
  • a first disadvantage is the slight inclination (10 to 15 degrees relative to the horizontal plane) of the axis common to the descending rotary conveyor, to the mixing zone of the mixture of dry pulverulent materials and water, and to the pump. eccentric screw allowing the suspension thus prepared to be sent. Consequently, this slight slope favors the flooding of the descending rotary conveyor when a backflow of water occurs from the mixing zone.
  • deposits of moistened materials are formed on the walls of the Archimedes screw of said conveyor, deposits which can harden by solidification and reduce the flow of dry powdery materials, but which can also detach and release under the form of crusts or agglomerates in the mixing zone.
  • Another disadvantage lies in the fact that the agitator of the mixing zone, in the form of a rectangular frame, is driven along an axis which is not coaxial with that of the envelope of said zone, so that it there are manifested regions without agitation in which hard deposits occur on the walls of the envelope leading to the same negative effects as those mentioned above with regard to the heterogeneity of the fluid aqueous suspension collected and of the device to be dismantled and cleaned.
  • a final disadvantage is caused by the accidental inclusion of air in the fluid aqueous suspension being formed.
  • the interstitial air present in the powdery mineral materials is entrained at the same time as the latter in the conveyor by a pump effect, due to the seal established between the Archimedes screw and its envelope. Consequently, this gaseous phase, which can escape, is included in the aqueous mineral suspension and constitutes for certain applications, in particular that of leveling surfaces, a major defect by the appearance of gaseous bubbles, very annoying, during the implementation of the suspension.
  • the object of the invention is to create a process and a device for preparing, transferring and applying a homogeneous, fluid, slightly aerated aqueous mineral suspension, meeting the assigned objectives and avoiding the drawbacks demonstrating in the state of the art.
  • the hopper for storing the mixture of powdery mineral materials, hydraulic binders and possibly other known constituents, of frustoconical or frusto-pyramidal shape is placed directly above the mixing zone and, in this way works by gravity. Upstream of its outlet orifice, the hopper is provided with a movable screen allowing to regulate the quantities of pulverulent dry matter to be delivered continuously.
  • the mixing zone which is not of vertical design, but whose axis is inclined relative to the horizontal plane, is (unlike the devices of the known art, except those of vertical design), supplied directly by the hopper, that is to say that it operates without the intermediary of a conveyor, such as an Archimedes screw in a cylindrical envelope.
  • a conveyor such as an Archimedes screw in a cylindrical envelope.
  • the mixing zone of downward inclination formed of a cylindrical envelope and of a coaxial mixing member, is of more restricted dimensions than in the devices of the known art.
  • the hopper feeds the mixing zone directly, i.e. it operates without the intermediary of a conveyor, such as a screw 'Archimedes in a cylindrical envelope.
  • the advantage of such a system lies in the fact that in the absence of any movement of the kneading member, the mixture of dry powdery materials is delivered, according to a natural slope of landslide, favored by the inclination of the axis of the mixing zone relative to the horizontal plane.
  • the mixing zone of downward inclination formed of a cylindrical envelope and of a coaxial mixing member, is of more restricted dimensions than in the devices of the known art.
  • the deliberately compacted mixing zone does not have any transfer intermediary for its supply of dry powdery materials: its supply orifice is therefore subject to the outlet orifice of the hopper. More than that, the kneading member extends over the entire length of the kneading zone and, thanks to this, sweeps the outlet opening of the hopper.
  • the kneading member constantly requests the incoming flow of powdery dry matter, quickly puts it in contact with the aqueous phase (thanks to its rotational movement and the downward inclination of the kneading zone), carries out the suspension aqueous pulverulent matter which travels immediately towards the downstream part of the mixing zone.
  • This mixing zone is also provided with a water supply, preferably placed laterally or on the upper part of the envelope and substantially in its middle part, the quantity of which is determined and controlled. (depending on the type of suspension to be prepared) by appropriate adjustment and control means.
  • the aqueous mineral suspension quickly prepared, has neither the time to incorporate air, nor that to rise, nor that to settle on the walls of the envelope, the latter being in particular subjected to a quasi-permanent scraping by the kneading member.
  • a non-return member for said materials is placed and a set of seals mounted on the drive shaft of the kneading member, which They also act as means of preventing the aspiration of air from upstream of the mixing zone.

At the outlet of the mixing zone, an eccentric screw pump is installed coaxially which continuously sucks the suspension in said zone and discharges it under pressure into a second mixing zone having the property of making the suspension homogeneous, and of the refine without airing it.
  • This second mixing zone according to the invention is provided with a shearing member.
  • This member can be chosen from the group consisting of link chains, one end of which is subject to the drive shaft, the other being free, by rotary turbines with sabers, blades, propellers comprising a or several branches located on one or more stages, the branch or branches of each stage being able to be angularly offset with respect to the branches of the other stages, the or at least one of the branches of each stage being able to be connected to at least one branches of the other stages by mechanical connecting elements, the said turbines being associated or not with fixed chicane plates mounted on the periphery of the envelope of said zone to increase the shearing phenomenon imposed on the suspension.
