Definitions

  • the present invention relates to a device and a method for the selective separation of a granular material comprising a fraction of massive particles comprising filiform particles and coarse particles and a fraction of fine particles.
  • Such a method is for example known from the document US4185746 which relates to a particle size separation device based on the introduction of granular materials comprising coarse particles and fine particles into a rotating circular plate, according to the preamble of claim 1.
  • the document EP726817 describes a method and an apparatus for separating filiform elements from other elements also originating from electronic equipment.
  • the principle of this device is identical to that of the document EP1712301 with the difference that the surface of a moving carpet is provided with bristles in which the filiform particles are fixed.
  • the document DE4117029 relates to the particle size separation of filiform particles from a mixture of particles of various shapes and sizes.
  • the separation of threadlike particles is based on the use of inclined conveyor belts driving the threadlike particles upwards while the particles of larger sizes slide along the conveyor belts under the action of the force of gravity.
  • the document DE9017891 relates to a method using a device also consisting of conveyor belts which are provided, on their surface, with bristles to fix the filiform particles.
  • the separation of filiform particles is carried out in the same way as that described in the document DE4117029 , the presence of hair here reinforcing the rise of threadlike particles at the top of the mats.
  • Screening methods are also known from the state of the art for the selective separation of a granular material comprising filiform particles and fine particles. Screening methods are based on the use of screens to filter solids of different sizes.
  • the devices and methods of the state of the art suffer from problems of clogging linked to the accumulation of filiform elements, for example twisted, at the level of the fibers and the bristles of the wheels or carpets, which does not allow to obtain an optimal separation of the filiform elements and elements of different grain sizes.
  • These screening methods also have a relatively long residence time for efficient separation of threadlike particles.
  • said threadlike particles constitute as many additional attachment points for other threadlike particles, which generally complicates the operations.
  • the object of the invention is to overcome the drawbacks of the state of the art by providing a device for the selective separation of a granular material comprising a fraction of massive particles and a fine particle fraction according to claim 1 and a process according to claim 3.
  • Such a device and such a method make it possible to avoid any clogging linked to the presence of filiform particles and ensure correct separation of the fraction of massive particles from the fraction of fine particles because each of the two aforementioned fractions are respectively subjected to a particular displacement.
  • material which has the effect of selectively separating each of the two fractions. Indeed, provided that the speed of rotation of said rotating circular plate is at least equal to 50% but less than 100% of the critical speed of rotation, the fraction of massive particles undergoes a displacement according to a cascade regime while, simultaneously , the fraction of fine particles undergoes a displacement according to a cataract regime.
  • the fine particles subjected to the cataract regime, describe trajectories passing through the center of said rotating circular plate where they are concentrated.
  • the massive particles subjected to the cascade regime, describe shorter trajectories than those of the fine particles and do not pass through the center of said rotating circular plate.
  • the cascade regime causes massive particles to fall on top of each other, causing these massive particles to collide. A collapse and a fallout of the massive particles on themselves is thus obtained.
  • the granular material is also distributed according to two other criteria.
  • the granular material is pressed against the peripheral edge of said plate circular rotating and, on the other hand, the granular material is distributed in several layers according to the density of the particles, the finest and densest particles forming the lower layers while the more massive and less dense particles form the layers superior.
  • the particles are also subjected to the force of gravity. Fine particles, which are dense but small in size and therefore light, are less subject to the force of gravity, while heavier particles, which, although less dense, are larger, are more strongly subject to it, resulting in these more quickly down. Since, as described above, the particles are subject to dragging forces, the effect of the force of gravity on the particles results in their ability to describe more or smaller trajectories, the denser and lighter fine particles describing larger trajectories than the heavier and less dense particles.
  • the distribution of the particles in different layers according to their density but also the different trajectories described by the particles according to their density and according to the displacement of the material (cascade or cataract) to which they are subjected makes it possible to obtain a selective separation, when the displacement of the granular material in the rotating circular plate having an inclined bottom takes place at a speed of rotation at least equal to 50% but less than 100% of the speed of rotation of said rotating circular plate. According to this particular speed of rotation, the displacements of matter according to the cascade and cataract regimes are obtained simultaneously in a surprising manner.
  • the massive particles float on the surface of the granular material while the fine particles are concentrated at the bottom of the rotating circular plate in a central collection zone.
  • fraction of massive particles is meant, within the meaning of the present invention, a fraction of matter granular comprising thread-like particles and/or coarse particles.
  • filament particles is understood to mean, within the meaning of the present invention, particles having a preferential direction but also wavy parts and which can therefore roll up on themselves or become entangled with each other. These are, for example, pieces of cable.
  • centimeter particles is understood to mean, within the meaning of the present invention, particles having a size of between 0.2 and 200 mm.
  • fine particles is understood to mean, within the meaning of the present invention, particles having a size of between 0.01 and 133 mm.
  • d 80 of the particles coarse / d 80 of the particles fine > 1.5
  • d 80 of the coarse particles means that 80% of the coarse particles of the granular material have a size less than a size between 0.2 and 200 mm
  • d 80 of the fine particles means that 80% of the fine particles of the granular material have a size less than a size between 0.01 and 133 mm.
  • said rotating circular plate has, in a trigonometric frame, a first quadrant extending from 0 to 90°, a second quadrant extending from 90° to 180° and a third quadrant extending from 180° to 270° with respect to a point 0 corresponding to a highest point of said rotating circular plate when the latter is stationary, said filiform particles and/or said coarse particles being recovered in a peripheral manifold in the form of a fixed descending ramp along at least part of said third quadrant of said rotary circular plate, along an arc between 180° and 270°, after their overflow from said rotary circular plate, said filiform particles agglomerating together in the form of pellets.
  • Such a positioning of said peripheral collector ensures optimum recovery of the filiform particles agglomerated in the form of balls which, by overflowing from said rotary circular plate, fall into said collector which directs them towards a collection zone.
  • said recovery of said fine particles in said central collection zone of said inclined rotating circular plate is carried out manually, preferably by suction, preferably via at least one opening made on the bottom of said central collection zone, preferably using an endless screw.
  • a separation of said coarse particles from said agglomerated filiform particles in the form of balls is carried out by means of a finger screen located in the extension of said peripheral collector.
  • the coarse particles pass through the fingers of said finger screen and thus end up in a first recovery tank while the pellets remain on the surface of the finger screen and are directed towards a second recovery tank located downstream of said first recovery tank.
  • the rotating circular plate is inclined at an angle ⁇ comprised between 20° and 80°, preferably comprised between 30 and 60°, preferentially comprised between 45 and 55° with respect to a plane horizontal.
  • Such a device for separating a granular material comprising massive particles (filiform + coarse) and fine particles advantageously makes it possible to avoid any clogging linked to the presence of filiform particles, the separation not resorting to the use of elements provided with fibers or bristles or the use of screens but with a rotating circular plate having a bottom inclined with respect to a horizontal plane and a peripheral edge extending in a flared manner upwards from this background.
  • this device allows selective separation, said filiform elements agglomerated in the form of balls as well as the coarse particles being recovered at the periphery of said rotary plate while said fine particles are concentrated in the center of said rotary plate in said collection zone of said fine particles .
  • said fraction of massive particles comprises filiform particles and coarse particles.
  • said second zone for collecting said fine particles comprises at least one opening made on the bottom of said central collection zone or an endless screw.
  • FIG. 1 illustrates an embodiment of the device for separating a granular material according to the invention.
  • the granular material comprising filiform particles (1), fine particles (2) and coarse particles (3) is introduced into the rotating circular plate (5) via a feed ramp (4).
  • the rotating circular plate (5) is inclined at an angle ⁇ (indicated in picture 3 ) with respect to a horizontal plane and rotates around a central axis (6) clockwise (direction indicated by the arrow) at a speed of rotation at least equal to 50% but less than 100% of the critical speed of rotation of said rotating circular plate (5) so that displacements of the material according to the cascade regimes (displacement illustrated by the large dashes) and cataract (displacement illustrated by the small dashes) are obtained simultaneously.
  • the fine particles (2) are subjected to the cataract regime and describe trajectories passing through the central collection zone (7) where they accumulate.
  • the filiform particles (1) and the coarse particles (3) are subjected to the cascade regime which causes the massive particles (filiform + coarse) to fall on top of each other. This has the effect that the filiform particles (1) collide with each other and form balls (8) by becoming entangled.
  • the filiform particles in the form of balls (8) as well as the coarse particles (3) float on the surface of the granular material supplied and are recovered by overflowing above the peripheral edge (9) of the rotary circular plate (5), following their drive down by the force of gravity, in a peripheral collector (10).
  • the fine particles (2) are concentrated at the bottom of the rotary circular plate (5) in the central collection zone (7) and are recovered by flow via openings (11) made in said central collection zone (7) To proximity to said axis of rotation (6).
  • Said peripheral collector (10) is extended by a finger screen (12) allowing coarse particles (3) sliding along said peripheral collector (10) to fall into a first collection tank (13) through the fingers of said fingers (12).
  • the filiform particles in the form of pellets (8) slide over the finger screen (12) before being recovered in a second recovery tank (14).
  • FIG. 2 illustrates another embodiment of the device for separating a granular material according to the invention and is identical to the figure 1 with the exception that an endless screw (15) ensures the recovery of fine particles (2) concentrated at the bottom of the rotary circular plate (5) in the central collection zone (7) close to said axis of rotation (6) .
  • a deflector (16) directs the fine particles (2) towards the central collection zone (7) ⁇ one end of said endless screw (15) is arranged to extract said fine particles (2 ) agglomerated in said central collection zone (7).
  • FIG. 3 is a side view of the device for separating a granular material according to the invention in which the angle of inclination ( ⁇ ) of the rotary circular plate (5) is illustrated.
  • the grinding residue introduced into the tray includes filiform particles (for example sheathed or unsheathed electric wires), massive (coarse) plastic and metal particles and fine particles (mineral fraction).
