Definitions

  • an inner wall of the body includes a plurality of vanes or fins for controlling the direction of the flow of fluid through the passage, during use.
  • the vanes or fins are provided in a collar member positioned along an inner wall of the body.
  • the nozzle comprises a plurality of spaced apart surfaces, said surfaces defining a fluid flow cavity extending substantially around a peripheral portion of the body, wherein the pressurised fluid is received into the cavity and released out of the nozzle through a mouth of the nozzle.
  • the cavity of the nozzle is defined by a first surface spaced away from a second surface such that the first and second surfaces converge towards each other to form the mouth.
  • the width of an opening defined by the mouth is less than 1.5mm.
  • the nozzle forms an in use Venturi tube, the nozzle comprising a converging entrance for receiving the pressurised fluid and a throat portion in fluid communication with the mouth, such that flow of the pressurised fluid through the throat portion increases velocity of the pressurised fluid and reduces static pressure of the fluid before exiting the nozzle through the mouth.
  • the nozzle includes one or more connectors for connecting one or more fluid lines for receiving pressurised fluid.
  • the nozzle includes: at least a first plurality of connectors for connecting a first plurality of one or more fluid lines and receiving a first pressurised fluid; and at least a second plurality of connectors for connecting a second plurality of one or more fluid lines for receiving a second pressurised fluid.
  • said one or more connectors are disposed at an acute angle relative to an imaginary longitudinal axis of the body.
  • the cavity of the nozzle is defined by an inner slanting surface of a section of a first hollow conical body, said inner slanting surfaced being spaced away from an outer slanting surface of a section of a second hollow conical body.
  • the body defining the passage is substantially cylindrical.
  • an outer wall of the body comprises one or more mounts for mounting the assembly to a mounting surface.
  • Figure 1 is a first perspective view of a ventilating assembly 100 in accordance with an embodiment of the present invention.
  • Figure 5 is an enlarged sectional view of the nozzle 50 that forms a part of a nozzle 50 provided in the ventilating assembly 100.
  • Figure 6 is a second perspective view of the ventilating assembly 100.
  • Figure 7 is an in-use third perspective view of the ventilating assembly 100 indicating fluid flow directions.
  • Figure 8 is a schematic illustration of a manifold 150 for supplying pressurized fluid to the ventilating assembly 100.
  • Figure 9B is a sectional enlarged view of ventilating assemblies 100A and 100B in a fluidly coupled configuration.
  • Optional collars/sleeves may be inserted into passage of the body 30.
  • the collars or sleeves may be positioned along an inner wall of the body 30.
  • the collars or sleeves may include fluid flow directing vanes or fins positioned relative to the nozzle 50.
  • the pressurised fluid expelled by the mouth 59 of the nozzle 50 may be directed by the vanes or fins of the collars or sleeves positioned in the body 30.
  • a ventilating system 1000 may be provided by inter-connecting two or more of the ventilation assemblies 100A, 100B, 100C, 100D and 100E in series by an inter-locking mechanism that allows passage of fluid between two inter-connected ventilating assemblies 100 as illustrated in Figure 9A.
  • a peripheral portion of the inlet 22 and the outlet 42 of the body 30 in each assembly 100 include respective engaging portions for allowing the inter-locking of two more ventilating assemblies 100 (for example 100A and 100B) that are connected in series as shown in the enlarged view in Figure 9B.
  • the ventilation assembly 100 provides several significant advantages. First, the ventilation assembly 100 does not require any movable parts such as fan blades or electrical circuitry which results in significant reduction in costs and also improves manufacturability. Secondly, the ventilation assembly 100 provides dust suppression in underground mines thereby reducing the possibility of mining workers being affected by "black lung" disease.
  • the ventilation assembly 100 may be provided in a wide range of sizes ranging from 250mm up to 280 mm and the assembly 100 is particularly useful in underground mining environments which are confined where dust (such as coal dust) is a problem.

Abstract

La présente invention concerne un ensemble de ventilation destiné à ventiler des mines souterraines, l'ensemble comprenant : un corps définissant un passage allongé pour permettre l'écoulement d'un fluide à travers ce dernier, le passage étant positionné par rapport à un orifice d'entrée destiné à recevoir un fluide et un orifice de sortie destiné à expulser le fluide, un agencement de fixation destiné à fixer le corps à une structure de support et une buse positionnée vers l'intérieur dans le corps pour libérer un flot de fluide sous pression dans le passage pour aspirer un flot de fluide dans le passage à travers l'orifice d'entrée et diriger l'écoulement de fluide dans le passage dans une direction générale depuis l'orifice d'entrée vers l'orifice de sortie.
