Definitions

  • the most usual system is that of the large fixed hood where evacuation is ensured either by lowering of pressure or by the a-id of a mechanical suction system and under which the possible sources of fumes or vapours are placed.
  • the apparatus of the invention is about twenty times more etiicient, for the same energy consumption, as are conventional function hoods.
  • the socket can be blocked in any position by some system of screws.
  • the micro-hood proper which has a generally hemispherical shape, is composed of a lower round orifice, through which penetrates fumes and vapours, of a filtering system which will be adapted to each type, of a turbine giving the fumes and vapours a helical movement which projects them into an evacuation chamber then into the previously mentioned horizontal outlet pipe, connected to a conduit or equipped "ice with a purifier for escape into the atmosphere.
  • the motor driving the turbine is secured under a cowl on top of the hemisphere.
  • the foot 1 of the apparatus in the form of a V of which one horizontal branch rests per pendicularly on two supports 1a and 1b, the other branch terminating by the cylindrical vertical rod 2 making therewith a largely obtuse angle on which can slide and be blocked for example by means of blocking screw 3a, a socket 3 rigid with exhaust pipe 4 of the apparatus itself.
  • Above support 7 is a wall 10 central opening 11.
  • Above wall 10 is Ilocated turbine 15 and its vertical driving shaft 16.
  • support 17 which includes an opening 18 through which passes shaft 16 rests motor 19 driving shaft 16 and turbine 15 in a rapid rotational movement around the general axis O, O', creating a centrifugal force suicient for ensuring the evacuation of vapours and fumes into evacuation chamber C then by exhaust pipe 4, into a conduit or into the atmosphere after purification.
  • Motor 19 is surmounted by a cowl 20 having the shape of a spherical cap, secured to the body of the apparatus by two fasteners 21 and 21".
  • a part of the hemisphere 5 and of the cap 20 appear in dotted lines on ⁇ the iigure owing to the fact that the exhaust pipe 4 opening on chamber C, forms a nozzle on the hemispherical shape.
  • Portable exhaust device comprising a base carrying a vertical support; an exhaust member for gases and fumes adjustably mounted on said support, said exhaust member having an inlet forming an evacuation chamber and an outlet for said gases and fumes, said exhaust member carrying and communicating with a hemispherical hood adapted to be placed above a source which emits said gases and fumes; said hood having at its lower extremity a horizontal support, a wall member positioned at a distance above said support so as to form a periph eral opening therebetween and forming part of said evacuation chamber, said wall member having an opening therein communicating with said hood, a filter in said peripheral opening between said wall member and said support such that gases and fumes emanating from said source must pass through said lilter and driving means for urging said fumes and gases through said evacuation chamber and thence through said exhaust.
