Definitions

  • the present invention relates to an ejector of granular material, in particular sand, intended to be fixed to a container for granular material.
  • the present invention relates more particularly but not exclusively to such an ejector associated with a sandblaster for spreading sand on a rail in front of a railway vehicle wheel, for example a locomotive.
  • a sandblaster is intended, during an emergency or normal braking, to spread sand on the rail, below the braked wheel, to prevent slippage, increase efficiency braking and reduce the stopping distance.
  • the sandblaster is also used during startup to improve adhesion.
  • the sander container usually contains a sufficient amount of sand to dump during the entire braking period leading to a complete stop of the train, from its maximum possible speed on the path considered, or for the duration of a start-up.
  • a sandblaster To control sand ejection, a sandblaster generally has a separate ejector container attached to the bottom of the sander container, which allows easy maintenance does not require disassembly of the assembly to access the essential functional parts. Such ejector may further be arranged so that it allows a mixing and drying of the sand.
  • An ejector for sandblaster is known from the document FR-A-2,713,182 .
  • This ejector has opening control means comprising a movable piston cooperating with an annular flow seat. The movement of the piston is guided by a cylinder block.
  • This ejector has the disadvantage of including a piston movable in a guide structure, which makes it bulky and expensive to mount.
  • the mobile piston and its guide structure are intended to operate in an aggressive environment due to the presence of sand which implies significant maintenance costs.
  • Another ejector is known from the document US-A-4,325,573 .
  • This ejector has a sand discharge pipe surmounted by a protective shield.
  • This ejector has the risk of untimely emptying of sand under the effect of vibrations and upwellings of water and moisture in the sandpit, Moreover this ejector has a large vertical footprint because the sand discharge pipe must penetrate far enough into the container to allow the sand to enter the discharge pipe through the bottom of the shield under the effect of a flow of air, and the presence of an exhaust pipe that must penetrate in the container up to the maximum level that can reach the sand.
  • Another disadvantage of this ejector is that it does not allow to use all the sand of the container, because of the raised position of the inlet of the discharge pipe.
  • the present invention aims to provide an ejector for granular material does not have at least some of the disadvantages of the prior art.
  • the invention provides an ejector of granular material, comprising a body, intended to be fixed to the bottom of a container in an operating position of said ejector, said body defining a passage suitable for a flow of granular material from the internal to the outside of said container, pressurized gas controlled closure means adapted to prevent or allow said flow of granular material through said passage, a gas supply circuit connectable to a pressurized gas source, for controlling said closing means, said gas supplying circuit comprising an outlet conduit arranged to be able to produce a flow of gas in at least a portion of said passage for propelling said flow of granular material out of said container, characterized in that said closure means comprise at least one resilient valve attached to said body for closing said passage in a rest position of said valve, and adapted to deform elastically under the effect of said gas flow so as to allow flow of granular material through said passage, said passage comprising, upstream of said valve relative to said flow, a zone baffle capable of imposing at least one change of direction in
  • the material ejector thus designed does not require any moving parts to control the flow of material. Indeed, in operation, the elastic valve is elastically deformed by the gas flow and thus passes a certain flow of material propelled by this flow; then it returns to its rest position when the flow of gas is interrupted.
  • the baffle zone of the passage makes it possible to take back at least part of the charge created by the mass of material present in the container, so that this charge can not permanently deform the valve towards its passing position.
  • the valve prevents inadvertent flow of granular material and the rise of water and moisture to the container.
  • the ejector thus designed also has the advantage of having a regular flow of material, which is important in the application of the braking of a train.
  • the material contained in the container does not arrive near the ejector with a constant speed.
  • the flow resistance created by the baffled zone and the valve in its deformed position, as well as the air flow that propels the sand, can serve to reduce or cancel the effects of this variable speed, that is, ie to standardize the speed of ejection of the material.
  • the valve is fixed in a rectilinear portion of the passage intended to guide the flow of granular material from top to bottom in said operating position of the ejector.
  • the baffle passage zone comprises a rising passage portion, placed upstream of said rectilinear portion and configured to guide said flow of granular material from bottom to top, in said operating position of the ejector.

  • the valve is advantageously fixed to said base at a level of end of the bore.
  • the mounting of the valve on the base is then easy.
  • the base comprises an anti-abrasive protection sheath protecting at least a portion of the walls of the bore. This allows the body to use a lightweight material that does not have to be abrasion resistant.

  • the gas outlet duct is fixed projecting on a face of the cap facing towards the base, said gas outlet duct being oriented in alignment with said first tube and said bore. and having an open end opening directly in front of the valve.
  • a flow of propellant gas is produced in the direction of the rectilinear passage portion and thus has a high efficiency for opening the valve and driving the material out of the ejector.
  • the gas supply circuit comprises a first portion dug in said base, a connecting duct connecting said first circuit portion to the cap and a second portion dug in said cap between said connecting duct and the outlet duct.
  • the gas supply circuit advantageously comprises a stripping duct provided with an end intended to open, in said operating position of the ejector, inside the container, to create another flow of gas for stirring and drying the granular material.
  • the end of the straightening duct is arranged so as to orient at least a portion of the other flow in an inlet portion of the passage for the flow of granular material.
  • the backwash flow also contributes to the flow of the material, and the efficiency of the ejector is increased. This also contributes to the regularity of the flow.
  • the stripping duct is dug into the base and branches on a portion of said gas supply circuit also dug in the base.
  • Such an embodiment is particularly compact and makes it possible to use a single source of pressure for the functions of freeing and propelling the material.
  • a porous body is arranged at the end of the straightening duct to diffuse said gas flow for the stirring and drying of said granular material.
  • the valve comprises a flat element made of elastomeric material, preferably pierced with a central hole and cut into a star.
