Definitions

  • the invention relates to a device for the production of bituminous coated products from bitumen aggregates and solid materials which can undergo degradation if they are exposed to a medium at high temperature.
  • Such a device also has the advantage of preventing the aggregates introduced into the drum from falling into the flame, which avoids the formation of dust by bursting of these aggregates under the effect of the heat of the flame.
  • Such a device is not suitable in the case where it is desired to introduce into the drum solid materials containing bitumen, such as recovered bituminous mixes or any other solid material which can be degraded if it is exposed to a medium at high temperature.
  • Such solids can be, for example, compounds rubberized plastics, plastics, sulfur, coloring products such as a metal oxide, or bitumen in flakes.
  • D t is known other devices for the production of asphalt from nine aggregates, bitumen as well as a certain proportion of recycled coated when recycled asphalt is introduced into the drum in an intermediate zone between 'entry end through which the new aggregates penetrate and the exit end of the drum through which the asphalt is discharged.
  • the principle of constituting a curtain is used with the new aggregates introduced into the drum, the recycled aggregates being introduced into an area of the drum protected from the flame by this curtain of materials.
  • the recycled materials are introduced into the drum through openings made in the wall of this drum. And mechanical devices, such as hatches which close by gravity, make it possible to prevent the material from coming out of the drum at this area. intermediary for the introduction of recycled materials.
  • the drying zone for the new aggregates comprises revealing devices which allow the new aggregates to fall over the entire section of the drum and in particular in the flame of the burner.
  • these devices require mechanical members such as hatches movable relative to the casing of the drum at the level of the intermediate zone for introducing recycled materials. Under the operating conditions of the drum, it is undesirable to use such movable closing devices.
  • the object of the invention is therefore to propose a device for the manufacture of bituminous coated products from aggregates, bitumen and solid materials, such as recycled coated materials which can be degraded if they are exposed to a medium at high temperature, comprising a drum rotating around its axis, slightly inclined on the horizontal, inside which circulate, in the same direction, the solid products and the hot gases coming from a burner penetrating by the entry end of the drum through which also new aggregates penetrated by means of feeding into the first zone of the drum following this entry end, or introduction zone, the drum being supplied with solid materials such as recycled asphalt, at an intermediate zone arranged between the entry end and the outlet end through which the products circulating in the drum are evacuated and preceding in the direction of circulation of the products a hot mixing zone into which the bitumen is introduced and where the products s are lifted throughout the section of the drum by lifting devices and brought into contact with the hot gases passing through the drum, this device having to avoid contact of solid materials such as asphalt recycled with an atmosphere at too high temperature, -to avoid direct
  • Figure 1 shows a sectional view through a vertical plane of symmetry of the drum and the associated devices associated therewith.
  • Figures 2, 3, 4 and 5 are cross sections of the drum at sections 2-2, 3-3, 4-4 and 5-5 of Figure 1 ..
  • the outlet end 3 of the drum opens into a hopper 10 which allows, on the one hand, the evacuation of the gases from the burner having passed through the drum and possibly entrained particles and, on the other hand, the outlet of the mixes (arrow 12).
  • outlet face 3 of the drum also penetrates into this drum a device 14 for supplying hot and molten bitumen which ends in a spraying ramp 15 making it possible to distribute the bitumen on the solid materials in the last zone of the drum.
  • the drum comprises successively from its entry to its exit, that is to say from the right to the left in FIG. 1, an introduction zone 16, a transfer zone 17, an intermediate zone 18 and a mixing zone 19 in which the addition of bituminous binder takes place via the spray boom 15.
  • the flame 9 of the burner extends in zones 16 and 17, that is to say in the introduction zone and in the transfer zone.
  • the internal surface of the drum carries fins 20 arranged helically on the wall of the drum and projecting, so that the new aggregates 7 arriving by the entry face of the drum are rapidly introduced into the transfer zone 17 after an extremely short journey time in the zone 16 where these materials 7 remain in contact with the wall of the drum. During this rapid transfer to an area away from the flame, the materials undergo practically no drying and produce no dust.
  • the drum is lined in the transfer zone 17 of blades 22 kept apart from the wall of the drum 1 by means of spacers 23, the blades 22 constituting screen blades being constituted by sheets folded in U whose hollow surface for receiving the material 7 is directed towards the wall 1 of the drum.
  • the material 7 during the rotation of the drum in the direction of the arrow 25 is retained by this hollow surface directed towards the wall of the drum and driven upwards, then downwards inside the vanes 22, the sectbn of which has the shape of an asymmetrical U.
  • the vanes 22 constitute, by their flat surface directed towards the flame of the burner 9, screens protecting the material 7 constituted by the new aggregates.
  • Hot gases passing through the drum from the burner to the outlet end do not cause large amounts of dust.
  • the aggregates contained in the screen vanes 22 also protect the wall 1 of the drum against the heat of the burner flame by absorbing part of the heat of this flame.
  • the aggregates therefore undergo heating and the onset of drying in this zone by conduction of heat through the screen vanes.
  • this arrangement improves the efficiency of the installation because the heat evacuated by the wall 1 of the drum at this zone is considerably reduced.
  • the intermediate zone comprises two separate parts, the first part, the cross section of which is shown in FIG. 3, being an area for constituting a continuous curtain of materials and the second part, shown in Figure 4, an area for introducing solids fearing too high temperatures.
  • the drum In the first part of the intermediate zone, the drum has on its internal surface several sets of lifting vanes 28 angularly offset along the length of the drum to form a continuous dense and opaque curtain of aggregates 7 throughout the cross section of the drum.
  • These lifting vanes have a shape having a concavity towards the internal surface of the drum and are constituted by folded sheets.
  • the drum is surrounded at the second part of the intermediate zone, by a fixed device for introducing recycled materials 29 comprising an introduction hopper 27 and a closed cylindrical body 30 surrounding the drum with a slight clearance allowing the rotation thereof.
  • the drum further comprises at this intermediate zone, in addition to its external envelope 1, an internal envelope or second envelope 31 coaxial with the first which extends over the entire second part of the intermediate zone up to the entry to the mixing zone 19.
  • This internal ferrule 31 carries on its inner wall sets of vanes 32 comparable to the vanes 28 of the first part of the intermediate zone.
  • chutes 36 projecting outwardly making it possible to introduce the materials entering through the hopper 27, in the space between the drums 1 and 31, furnished with fins 35.
  • the troughs 36 include guide surfaces 33 inclined for the introduction of the materials through openings 34 of the drum 1.
  • the helical fins 35 are arranged so that during the rotation of the drum and of the ferrule 31 which is integral with the envelope of this drum, the fins helical 35 drive the recycled products 29 to the hot kneading zone 19 where these recycled materials 29 mix with the new aggregates 7 arriving through the internal part of the shell 31.
  • the new aggregates undergo an intensive and complete drying since they are exposed throughout the section of the drum to hot gases coming from the burner both at the level of the first part and of the second part of this zone. intermediate.
  • the aggregates 7 which enter the hot mixing zone are therefore perfectly dry.
  • the internal wall of the drum comprises, at the level of the hot mixing zone, lifting vanes having a certain concavity making it possible to carry out a lifting of the materials and a fallout of these materials throughout the section of the drum where these materials are exposed to the gases circulating in the drum at the level of zone 19.
  • Hot mixing takes place in zone 19 so that the mixture of new aggregates, liquid bitumen and recycled aggregates joined to the action of hot gases circulating in the drum at this level produces coated materials of equivalent quality to materials produced only by mixing new dried aggregates and bitumen, the bitumen of recycled aggregates being remelted under the effect of heat.
  • the materials leaving by the face 3 of the drum in the hopper 10 are therefore constituted by coated materials completely comparable to coated materials obtained by a process without introduction of recycled materials.
  • the main advantages of the device according to the invention are on the one hand to avoid the fall of new aggregates in the burner flame thanks to the screen vanes. which also produce with these other aggregates an insulation of the wall of the drum; on the other hand that the zone where recycled materials and liquid bitumen are introduced is perfectly isolated from the zone where the flame is located which is confined behind a very curtain. dense of materials and that the device for introducing recycled materials into the drum does not have any moving part with respect to the drum.
  • the screen vanes of the transfer area of the drum can have a shape with sharp angles and be made of folded sheets with a section comparable to that shown in FIG. 2 or, on the contrary, consist of a sheet folded along a curved surface. . In all cases, the hollow surface or the concavity of the curved surface is directed towards the internal wall of the drum.
  • the device was used to manufacture mixes from new materials and from a certain proportion of recycled materials. But it is also possible to use the device according to the invention to produce coated materials from new materials and from a certain quantity of additive elements fearing exposure to too dense heat, such as rubber compounds , plastics, sulfur, coloring products such as iron oxide or bitumen in flakes.
  • the invention applies in particular but not exclusively to the production of bituminous mixes for road surfaces.
