Definitions

  • ballast strippers of the ballast of the railways most used today are equipped with screens constituted by inclined screens on which the ballast flows.
  • the sieves are animated by vibrations generated by unbalances.
  • the subject of the present invention is a screening device of high efficiency and small size, easily adaptable to the specific conditions of the ballast to be screened constituted by a conveyor-separator simultaneously allowing a screening action to separate the elements of the ballast of a caliber less than that prescribed and the earth from the other elements of this ballast and transport these other elements of the ballast to a desired destination.
  • Figures 6 to 8 are block diagrams illustrating different possible variants of rotary shafts and the active elements they carry.
  • the present screen comprises a plurality of active screening elements causing the ballast to be agitated in order to separate the soil, its screening and its transport to a desired destination.
  • the present screen can be used to convey the ballast, during its screening, either horizontally, or along an inclined up or down plane. It is therefore possible, simultaneously with screening, to transport the ballast from a low point to a high point of the machine on which it is mounted, which allows the production of simpler machines by eliminating conveyors, and more compact.
  • the first embodiment of the screen, illustrated in Figures 1 to 3, for the removal of soil and ballast elements of a caliber less than the prescribed caliber is constituted by a conveyor-separator.
  • This conveyor-separator comprises a plurality of active screening elements 1, formed here by discs. These discs 1 have at their periphery notches 2 or tooth-shaped formations 3. These discs 1 are mounted on rotary shafts 4 of parallel axes driven in rotation, all in the same direction, by motors 5. Each rotary shaft 4 is pivoted in bearings 6 rigidly fixed to the side walls 7 of a container 8 intended to receive the ballast to be treated.
  • Each shaft 4 has at its ends toothed wheels 9 meshing with chains 10.
  • Each motor 5 drives one of the shafts 4 directly, as well as the shaft which precedes it via a chain 10.
  • the pairs of shafts 4 can be started up successively. It is also possible to have different rotational speeds between the pairs of shafts driven by different motors.
  • the speed and the direction of rotation of the different shafts can be adapted separately to choose the quality according to the conditions of the ballast and adapt its speed of passage through the screening device.
  • the discs 1 are staggered and the assembly which they form with the shafts 4 constitutes the bottom of the container 8. This bottom has free spaces between the discs 1 and the shafts 4 whose dimensions correspond to those of the elements of the ballast to eliminate.
  • the elements of the ballast are introduced into the end A of the container 8 and are transported towards the end B thereof by the rotation of the discs.
  • the end B of the container can be at the same height as the end A of this container, it can also be above or below the end A of the container.
  • the active screening elements 1 the elements of the ballast are agitated and shaken, which causes their separation and the elimination of most of the earth which coats them. All the elements of the ballast whose dimensions are smaller than the prescribed gauge and the earths fall through the free spaces between the discs 1 and the shafts 4 and are thus eliminated.
  • the elements of the remaining ballast are themselves conveyed by the rotation of the discs 1 towards the end B of the screen where they are discharged.
  • the fraction of the ballast to be stored is conveyed from one end to the other of the screen, even if the output of the screen is higher or at the same height as its entrance.
  • the screen illustrated in Figures 4 and 5, it comprises a container 11 provided with an openwork bottom 15. Under the bottom 15 are arranged active screening elements constituted by parallel axes 12 each carrying a cylindrical drum 13 provided with drive formations or teeth 14. These axes 12 are driven in rotation, all in the same direction, as in the first embodiment described by a motor 18.
  • the teeth 14 of the different drums 13 are aligned in the longitudinal direction of the screen and pass during their rotation through the holes in the bottom 15.
  • the holes in the bottom 15 are larger than the section of the teeth 14 so as to provide free spaces of a dimension corresponding to the size of the elements of the ballast to be eliminated.
  • the plates forming the bottom 15 can be interchangeable to modify the dimensions of the voids and therefore the size of the elements of the ballast to be eliminated.
  • This screen is also provided with a device for washing the ballast during its screening and transport, constituted by perforated pipes 16 supplied with water or washing liquid by conduits 17. These pipes 16 extend transversely relative to the screen and are located above and preferably between the drums 13. This washing device allows better elimination of the earth coating the elements of the ballast and reduces the dust generated by the operation of the screen.
  • FIG. 6 very schematically illustrates a variant in which the shafts 4 and the disks 1 which they carry are oval.
  • the discs 1 carried by two adjacent screens are offset by 90 ° .
  • FIG. 7 another variant is illustrated in which the circular discs 1 are mounted eccentrically on the shafts 4.
  • the corresponding discs carried by adjacent shafts are angularly offset from each other.
  • the variant illustrated in FIG. 8, on the other hand, is more particularly intended for a screen disposed along a rising inclined plane.
  • the shape of the teeth 3 of the discs 1 mounted on the shafts 4 is similar to a scraper bucket and allows elements of the ballast to be conveyed as far as the tooth of the disc carried by the neighboring shaft, imposing an elevation on them.
  • the transport of the ballast on the screening device is not done by gravity, but it is mechanically driven. Therefore, the screening device is not necessarily tilted downward. It can be horizontal or upright, which allows construction to easily comply with the requirements for rail gauge, even with a screening device of great length.
  • said motor shafts can be started and actuated successively, starting with those closest to the exit point of the ballast to be screened on the screening device, allowing said screening device to operate without any difficulty, even when the latter is in charge.
