Definitions

  • the present invention relates to the field of machines intended for the manufacture and/or renovation of roads in general. These machines are generally referred to as coating machines or coating plants.
  • a medium capacity coating plant may include a cylindrical drum configured to dry aggregates using a burner disposed at one end of the drum.
  • the interior surface of such a drum may have aggregate entrainment plates configured to disperse the aggregates in the hot air and the fumes diffused inside the drum by the burner.
  • the dimensions of the drum and the activity of the burner have a strong impact on the drying quality of the aggregates.
  • the energy consumed by the burner is very large and the dimensions of the medium capacity coating plant are relatively limited.
  • the length of the drum is therefore limited, as is the volume of fuel to supply the burner, which can affect the drying quality of the aggregates.
  • An object of the present invention is to at least partially resolve a drawback of the state of the art.
  • the subject of the invention is a device for drying aggregates for an asphalt production plant, the drying device comprising a cylindrical drum with an inlet end and an outlet end and a burner arranged on the side from the outlet end, aggregate drive plates being installed inside the cylindrical drum for dispersing the aggregates in the hot air diffused by the burner, with at least part of the drive plates having at their free ends cut slots and in that at least part of the drive sheets comprise a fixing wall and an end wall and in that the angle between the fixing wall and the end wall is between 100° and 160° and more particularly equal to 125°.
  • the slots cut in the free ends of part of the drive plates make it possible to evacuate the fines present among the aggregates as soon as they enter the drying device.
  • the drying time of the aggregates inside the drying device can be reduced, which makes it possible to limit fuel consumption by the burner and to reduce the dimensions of the drying device, particularly in length. and more particularly the cylindrical drum with the reduced size of the coating plant.
  • certain elements or parameters can be indexed, such as for example first element or second element as well as first parameter and second parameter or even first criterion and second criterion, etc.
  • it is a simple indexing to differentiate and name elements or parameters or criteria that are close, but not identical.
  • This indexing does not imply a priority of one element, parameter or criterion in relation to another and such denominations can easily be interchanged without departing from the scope of the present description.
  • This indexing does not imply an order in time either, for example to assess this or that criterion.
  • FIG. 1 shows a schematic representation of a mobile coating plant 1.
  • This coating plant 1 notably comprises loading hoppers 3a, 3b, in particular a loading hopper 3a for fines such as sand and a loading hopper 3b for aggregates such as gravel.
  • These fines and aggregates are transported by a first conveyor 4 to a drying device 5, such as a drying drum.
  • the fines and aggregates are then mixed with a hot hydrocarbon binder in a mixer 6 in order to form the coating.
  • the hot hydrocarbon binder can in particular come from a melter 9a.
  • the mix is evacuated via a second conveyor 7 to a temporary storage tank, to a means of transport or directly to the site to be used immediately.
  • Such a coating plant can in particular have a coating production rate of around 5 to 40 tonnes per hour.
  • the loading hoppers 3a, 3b, the first conveyor 4, as well as the melter 9a with hydrocarbon binder can thus be mounted on a trailer or on a tray which can be loaded on a trailer.
  • the drying device 5, the mixer 6 as well as the second conveyor 7 can be mounted on another trailer or another tray that can be loaded on a trailer.
  • the drying device 5 for the asphalt production plant 1.
  • the drying device 5 comprises more particularly a cylindrical drum 8 with an inlet end 8a and an outlet end 8b and a burner 9 arranged on the side of the outlet end 8b.
  • There figure 2 shows more particularly a section in the longitudinal direction of the cylindrical drum 8.
  • the cylindrical drum 8 has, for example, a length of four meters and a diameter of one meter.
  • the thickness of the wall of the cylindrical drum 8 is for example three millimeters.
  • the cylindrical drum 8 has a geometry of revolution around an axis of revolution inclined by three degrees. The slope thus created by this inclination favors the progression by gravity of the fines and aggregates towards the burner 9.
  • the progression by gravity of the fines and aggregates towards the burner 9 is illustrated in particular by double arrows F on the Figure 2 .
  • the drying device 5 further comprises drive plates 10 of aggregates being installed inside the cylindrical drum 8 for the dispersion of the aggregates in the hot air diffused by the burner 9. These drive plates 10 have a length much greater than their transverse dimensions.
  • the long side of the drive plates 10, indicated by double-headed arrows L on the Figure 2 is oriented parallel to the axis of revolution X of the cylindrical drum 8.
  • the drive sheets 10 At least part of them have slots 11 cut out at their free ends.
  • the free ends correspond in particular to a portion of the drive sheets 10 which is not in contact with the interior periphery of the cylindrical drum 8.
  • the slots 11 have for example a rectangular shape.
  • a rectangular shape is very simple to cut from a drive sheet 10.
  • the shape of the slots 11 is for example that of a “U”.
  • the slots 11 preferably have a thickness less than the average size of the aggregates and greater than the average size of the fines so that only the fines can pass through the slots 11. This makes it possible to improve the mixing and drying of the fines and aggregates.
  • the drive plates 10 are for example arranged in circumferential rows 15a, 15b, 15c, 15d, 15e, 15f and 15g on the inner periphery of the cylindrical drum 8.
  • the cylindrical drum 8 comprises for example seven circumferential rows 15a, 15b, 15c , 15d, 15e, 15f and 15g distinct.
  • the first circumferential row 15a is located at the inlet end 8a.
  • the last circumferential row, here the seventh circumferential row 15g is located at the outlet end 8b.
  • the circumferential rows 15b, 15c, 15d, 15e and 15f are located between the first row circumferential 15a and the seventh circumferential row 15g.
  • the number of circumferential rows can be greater than seven or even less than seven.
  • the drive sheets 10 having cut slots 11 are for example located at a maximum distance D corresponding to a quarter of the total length T of the cylindrical drum 8 starting from the inlet end 8a.
  • the drive sheets 10 located near the outlet end 8b therefore do not necessarily have slots 11 because the fines are a priori mainly evacuated by the slots 11 cut in the free ends of the drive sheets 10 near the inlet end 8a.
  • the circumferential rows 15a, 15b and 15c are in particular located at a maximum distance corresponding to a quarter of the total length T of the cylindrical drum 8 starting from the inlet end 8a.
  • a circumferential row 15a, 15b, 15c, 15d, 15e, 15f and/or 15g comprises for example between six and eighteen driving sheets 10 of the same length L, and more particularly twelve driving sheets 10 of the same length L
  • the drive sheets 10 forming the same circumferential row 15a, 15b, 15c, 15d, 15e, 15f or 15g can therefore all have the same length L and more generally have the same shape.
  • the drive plates 10 of two different circumferential rows do not necessarily have the same shape or the same length L.
  • the length L of the drive plates 10 can be increasing between the inlet end 8a and the outlet end 8b.
  • the drive plates 10 are spaced regularly on the inner periphery of the cylindrical drum 8, as indicated on the figure 2 And 3 .
  • a circumferential row 15a, 15b, 15c, 15d, 15e, 15f and/or 15g comprises for example twelve drive sheets 10
  • the angular distance separating two neighboring drive sheets 10 of the same circumferential row is for example 30°.
  • This configuration is illustrated in particular on the Figure 3 .
  • a circumferential row 15a, 15b, 15c, 15d, 15e, 15f and/or 15g comprises for example six drive sheets 10
  • the angular distance separating two neighboring drive sheets 10 is for example 60° .
  • the drive sheets 10 forming two adjacent circumferential rows are for example arranged in a staggered manner.
  • two adjacent circumferential rows each comprise for example twelve drive sheets 10
  • an angular offset of 15° can be observed in the arrangement of the drive sheets 10 forming these two adjacent circumferential rows.
  • This configuration is particularly visible on the Figure 3 on which a circumferential row is represented by twelve hatched driving sheets 10, this circumferential row being offset by 15° relative to an adjacent circumferential row represented by twelve non-hatched driving sheets 10.
  • At least part of the drive sheets 10 comprise for example a fixing wall 12 and an end wall 14.
  • An example of a drive sheet 10 is illustrated on the figures 4 and 5 .
  • these slots 11 are arranged in the free end of the end wall 14.
  • the fixing wall 12 serves in particular as a support for fixing the drive plates 10 on the interior periphery of the cylindrical drum 8.
  • the edges of the fixing walls 12 of the drive plates 10 are for example welded to the interior periphery of the cylindrical drum 8.
  • Brackets 16 allow the drive sheets 10 to be positioned inside the cylindrical drum 8.
  • the brackets 16 can also serve as reinforcements for the drive sheets 10 by opposing the forces exerted by the aggregates on the sheets drive 10 when the aggregates are scattered inside the cylindrical drum 8.
  • the brackets 16 are for example arranged along the fixing walls 12.
  • an angle ⁇ can be observed between the fixing wall 12 and the end wall 14, as illustrated in the Figure 5 .
  • the angle ⁇ is for example between 100° and 160°, and more particularly equal to 125°.
  • the angle ⁇ makes it possible to form a concave surface with the fixing wall 12 and the end wall 14. This concave surface is oriented in the direction of rotation of the cylindrical drum 8. It thus makes it possible to shovel the aggregates and fines when of the rotation of the cylindrical drum 8 to then scatter them in the current of hot air and in the fumes diffused by the burner 9 to dry them.
  • An angle ⁇ of 125° makes it possible more particularly to maximize the surface area which can be occupied by the aggregates and fines in the drive plate 10 while ensuring effective “shoveling”.
  • the drive plates 10 forming a first circumferential row 15a and a second adjacent circumferential row 15b located at the inlet end 8a are of the same length L.
  • the length L of these drive plates 10 is between ten and twenty-five centimeters and more particularly equal to fifteen centimeters. These are for example the shortest drive plates 10 among all the drive plates 10 installed inside the cylindrical drum 8.
  • brackets 16 spaced at least five centimeters apart which position the fixing walls 12 of the drive plates 10 forming the first circumferential row 15a and the adjacent second circumferential row 15b on the inner periphery of the cylindrical drum 8.
  • the drive sheets 10 forming the first circumferential row 15a and the second adjacent circumferential row 15b have slots 11 cut in their free ends.
  • the slots 11 cut in the free ends of these drive sheets 10 forming the first circumferential row 15a and the adjacent second circumferential row 15b form a comb. That is to say that the slots 11 are for example spaced regularly on along the drive sheets 10.
  • the spacing between two adjacent slots 11 is for example of the same order of magnitude as the width of the slots 11.
  • the slots 11 have, for example, a length of between five and ten centimeters and a width of between one and three centimeters.
  • the length of the slots 11 is oriented radially, that is to say perpendicular to the length L of the drive plates 10. It is therefore the width of the slots 11 which is parallel to the length L of the drive plates 10 and to the axis of revolution
  • the drive sheets 10 forming the first circumferential row 15a and the second adjacent circumferential row 15b have for example at their free ends between three and five slots 11 spaced with a minimum length equal to the thickness of the slots 11. According to another embodiment, the spacings between the slots 11 are not necessarily regular. Two neighboring slots 11 can for example be closer to each other than two other neighboring slots 11.
  • the drive plates 10 forming a third circumferential row 15c starting from the inlet end 8a have a length L at least twice greater than that of the drive plates 10 forming a first circumferential row 15a and a second circumferential row 15b adjacent to the inlet end 8a.
  • the drive plates 10 forming the third row 15c have for example a length L of fifty-five centimeters. They have at their free ends between three and five slots 11 spaced with a minimum length equal to three times the thickness of the slots 11. The spacing between the slots 11 is therefore for example between three and twenty centimeters.
  • the drive plates 10 forming the fourth, fifth and sixth circumferential rows 15d, 15e, 15f starting from the inlet end 8a have a length L equal to that of the drive plates forming the third circumferential row 15c starting from the inlet end 8a.
  • the drive plates 10 forming a fourth, fifth and sixth rows 15d, 15e, 15f therefore have, for example, a length L of fifty-five centimeters.
  • the drive plates 10 of the rows 15d, 15e and 15f have free ends without slots 11.
  • brackets 16 which position the fixing walls 12 of the drive plates 10 forming the third, fourth, fifth and sixth circumferential rows 15c, 15d, 15e and 15f adjacent to the inner periphery of the cylindrical drum 8.
  • the brackets 16 are regularly distributed along the drive plates 10. Two neighboring brackets 16 are for example eleven and a half centimeters apart.
  • the driving plates 10 of a last circumferential row 15g counted from the entry end and located at the exit end 8b are longer than the driving plates 10 of the other circumferential rows 15a to 15f.
  • the drive plates 10 of the last circumferential row 15g have for example a length L of eighty centimeters.
  • the last row circumferential row 15g located at the outlet end 8b also corresponds to the seventh circumferential row 15g starting from the inlet end 8a.
  • the drive sheets 10 forming the last circumferential row 15g counted from the inlet end 8a and located at the outlet end 8b comprise for example a fixing wall 12, a junction wall 13 and a wall end 14 without slots 11.
  • the angle ⁇ between the fixing wall 12 and the junction wall 13 is for example between 90° and 110°.
  • the angle ⁇ between the junction wall 13 and the end wall 14 is for example between 100° and 150°.
  • the walls 12, 13 and 14 can give a “claw” shape to the drive plates 10 forming the last row 15g.
  • This “claw” shape makes it possible in particular to accentuate the concavity of the drive plates 10 forming the last row 15g. This makes it possible in particular to shovel a larger quantity of aggregates during the rotation of the cylindrical drum 8.
  • brackets 16 which position the fixing walls 12 of the drive plates 10 of the last row 15g on the inner periphery of the cylindrical drum 8.
  • the brackets 16 are regularly distributed along the drive plates 10.
  • Two neighboring squares 16 are for example twenty-two centimeters apart.
  • the cylindrical drum 8 is rotated around its axis of revolution X.
  • the aggregates and fines are loaded into the drying device 5 and more specifically into the cylindrical drum 8 via its inlet end 8a.
  • the rotational movement of the cylindrical drum 8 disperses the aggregates and fines on the interior periphery of the cylindrical drum 8.
  • the drive sheets 10 recover part of the aggregates and fines in the concave surface formed by the fixing wall 12 and the end wall 14.
  • the drive sheets 10 make it possible to shovel the aggregates and promote their dispersion in the hot air and the fumes diffused by the burner 9.
  • the drive plates 10 forming the first circumferential row 15a and the adjacent second circumferential row 15b located at the inlet end 8a are for example very short.
  • the limited length L of these drive sheets 10 allows the aggregates to stay longer in the hot air, this can promote their rise in temperature and thus accelerate their drying.
  • the drive plates 10 forming the third, fourth, fifth and sixth circumferential rows 15c, 15d, 15e and 15f starting from the inlet end 8a are a little longer.
  • the greater length L of the drive sheets 10 forming the rows 15c, 15d, 15e and 15f can reduce the time the aggregates remain in the hot air diffused by the burner 9a. This makes it possible in particular to limit the risk of burning of the aggregates.
  • the drive sheets 10 forming the first circumferential row 15a, the adjacent second circumferential row 15b and the third circumferential row 15c have slots 11 cut out at their free ends. These cut slots 11 can make it possible to quickly evacuate the fines mixed with the aggregates poured into the cylindrical drum 8. Separating the fines from the aggregates at the inlet end 8a of the cylindrical drum 8 can reduce the drying time of the aggregates.
  • the claw shape of the drive plates 10 forming the last row 15g starting from the inlet end 8a makes it possible to increase the concave surface of the drive plates 10. This makes it possible to increase the quantity of aggregates shoveled during of the rotation of the cylindrical drum 8 around its axis of revolution
  • the claw shape of the drive plates 10 forming the last row 15g makes it possible, for example, to avoid burning of the aggregates. It also makes it possible to promote the evacuation of dry aggregates from the cylindrical drum 8 via the outlet end 8b.
