Definitions

  • the invention relates to an apparatus for feeding insulating material, such as rock wool or glass wool, into the cavity of a hollow wall, provided with an ejector, which on the one hand is connected to a supply pipe for the insulating material and which on the other hand is connected to a supply pipe for a gas stream, the insulating material being sucked into the ejector by this gas stream, said ejector being further connected to a discharge tube, from which the insulating material is blown into the cavity.
  • insulating material such as rock wool or glass wool
  • a pump supplies air under pressure to a first conduit, which divides into two branch conduits.
  • One of these branch conduits debouches into a reservoir for the insulating material, whilst the other branch conduit is connected to a first inlet leg of a Y-shaped connection part.
  • the second inlet leg of this Y-shaped connection part is connected to the outlet of the reservoir for the insulating material.
  • the outlet leg of the Y-shaped connection part is connected to a rather long conduit, which ends in the discharge tube.
  • the air under pressure which enters the first inlet leg of the Y-shaped connection part exerts a suction action in the second inlet leg of the Y-shaped connection part in order to support the supply of the insulating material from this reservoir by means of the air under pressure fed to this reservoir through the first mentioned branch conduit. Therefore the Y-shaped connection part operates as an ejector.
  • This known apparatus has the disadvantage, that although the suction effect exerted on the insulating material tends to loosen the insulating material the rather long conduit between the Y-shaped connection part and the discharge tube leads to a compression of the insulating material, which abolishes the loosening effect obtained by the suction action in the ejector.
  • the apparatus according to the invention is characterized in that the ejector and the discharge tube are combined in a discharge unit, which comprises a housing equipped with a central channel, the supply pipe for the insulating material being connected to this central channel at the side remote from the discharge tube, said central channel being provided with a first portion having a cross-section which becomes smaller in the direction towards the discharge tube, said first portion adjoining a second portion having an approximate constant cross-section, the supply pipe for the gas stream being connected to a plurality of gas channels formed in the housing, which gas channels debouch into the said second portion of said central channel, said gas channels enclosing an acute angle with the longitudinal axis of said central channel.
  • the insulating material Due to the divided gas supply through the plurality of gas channels according to the present invention it becomes possible to transport the insulating material to the ejector by suction only, so that an improved loosening effect of the insulating material which is sucked into the central channel by the gas flow is attained.
  • the insulating material is deposited via the discharge tube into the cavity while it still has its loosened state.
  • the drawing shows an apparatus for feeding insulating material such as rock wool or glass wool into the cavity 4 of a hollow wall consisting of an inner wall and an outer wall 10.
  • the apparatus is provided with an ejector which on the one hand is connected to a supply pipe 3 for the insulating material and which on the other hand is connected to a supply pipe for a gas stream, said ejector being further connected to a discharge tube 7, which debouches through a bore 9 in the outer wall 10 into the cavity 4.
  • the ejector and the discharge tube 7 are combined in a discharge unit, which comprises a housing 1 equipped with a central channel 2.
  • the supply pipe 3 for the insulating material is connected to the central channel 2 at the side remote from the discharge tube 7.
  • the central channel 2 comprises a first portion having a cross-section which becomes smaller in the direction towards the discharge tube 7, and a second portion having an approximate constant cross-section.
  • the supply pipe for the gas stream is connected to an inlet stub 6 on the housing 1, while the gas stream passing this inlet stub 6 reaches a main gas channel formed in the housing 1 and having a centre line coinciding with the centre line of the central channel 2. From this main gas channel the gas is fed to a plurality of gas channels 5 formed in the housing 1. These gas channels 5 debouch into the second portion of the central channel 2 with the approximate constant cross-section and enclose an acute angle with the longitudinal axis of this central channel 2.
  • the discharge tube 7 which is detachably mounted in the housing 1 may be provided with an end wall 11 and an outflow aperture 12 arranged in the side wall of the discharge tube 7.
  • a filling member 13 may be mounted in the discharge tube 7 to rectangularly deflect the flow of the gas and the insulating material.
  • the housing 1 may support driving means (not shown) by means of which the discharge tube 7 may be brought into rotation.
