Definitions

  • ABSTRACT A container with at least one nozzle for introducing turbulent compressed air into the container for transport of granular or sluggishly flowing material out of the container, which nozzle forms the outlet from a housing into which the air is pulsed by means of a rotor driven by the air entering the housing, which rotor may be eccentric balanced to produce vibrations of the housing in the container.
  • the invention relates to an improvement in a container for compressed air transport of granular material or sluggishly flowing material, for example, concrete, comprising at least one nozzle arranged on the inner peripheral surface of the container for introduction of compressed air and having a plate-shaped element pro vided with turbulence-producing channels provided in front of the nozzle.
  • a container is known for transport by means of compressed air of granular material or a sluggishly flowing mass.
  • the container comprises a funnel-shaped bottom part terminating in a discharge opening and at least one nozzle arranged for introduction of compressed air on the inner peripheral surface of the container, the axis of said nozzle being in oblique downward direction with respect to the axis of the container.
  • the nozzle here is provided with a plate-shaped element, located with its plane at right angles to the axis of the nozzle and provided with a plurality of through-channels arranged in a circle and obliquely disposed with respect to said plane in the same direction along the circle. A turbulent formation is thus produced for the compressed air which, in turn, effects an advantageous transport of the material.
  • the object of the invention is therefore to improve the effect produced by the compressed air nozzles, so as to improve the transport of the mass and improve the turbulence of the mass with less adherence to the walls of the container.
  • the plate-shaped element is mounted in a cylindrical housing connected to the nozzle, that a rotor is mounted in the housing between the elements and the end wall of the housing in order to produce vibrations, and that the compressed air is introduced into the housing through an inlet pipe arranged eccentrically or obliquely, with respect to the housing, on the peripheral surface of the housing in the area of the rotor.
  • the rotor may be formed as one or more rod-shaped elements having closure plates at least at one end thereof.
  • closure plates are then disposed obliquely with respect to the cylindrical surface of the housing.
  • the rotor thereby closes the supply of air substan tially completely each time it passes the air inlet and thus produces a pulsation which can be regulated by the number of rod elements with closure plates, and by means of the air pressure.
  • One closure element is generally adequate.
  • the rotor is rotated by the compressed air introduced and should therefore have a somewhat oblique disposition with respect to the cylindrical surface, so that the air introduced tangentially through the inlet exerts a displacing force on the plate. The fact that a small opening remains and complete closure is not achieved, is insignificant.
  • FIG. I the lower part of a container for compressed air transport, the means according to the invention being disposed on the peripheral surface of the container.
  • FIG. 2 an enlarged section of the means according to the invention.
  • FIG. 3A-C three embodiment examples of the rotor in the means, illustrated in diagram in a section along the line III-III.
  • FIG. 1 is a view of the lower funnel-shaped part 1 of a container for compressed air transport of granular material, or material which flows sluggishly, for example, concrete.
  • the part 1 is connected at the bottom thereof to a discharge pipe 2.
  • Compressed air is introduced into the container from a compressor, not shown, through nozzles 3 arranged in the wall of the container, the nozzles being integral with a cylindrical housing 4 surrounding the means according to the invention.
  • the compressed air is introduced into the housing 4 from the compressor through the pipe 5 which enters the cylindrical surface tangentially.
  • the means according to the invention is further illustrated on FIG. 2.
  • the nozzle 3 is connected to the housing 4, for example, by a screw connection.
  • the turbulence-producing, plate-shaped element 6 is mounted adjacent the nozzle 3.
  • a shaft 7 is arranged between the plate-shaped element 6 and the end wall 8 of the housing 4, on which shaft is secured a rotor 9.
  • the rotor 9 is arranged below the air inlet pipe 5.
  • the air inlet pipe 5 is obliquely disposed, in the example shown, tangentially with respect to the cylindrical casing of the housing 4.
  • the rotor is also formed as a rod-shaped element 9.
  • a plurality of rod-shaped elements may also be used, however, or another shape of rotor.
  • FIGS. 3A*C illustrate three different constructions of the rotor.
  • the rotor consists of the rod-shaped element 9 which rotates about the shaft 7 and is provided at one end with a closure plate M), the rod elements being provided at their other ends with a counter-balance or the like 11, so that the centre of gravity of the rotor is in the axis of rotation.
  • the closure plate 10 is of a shape such that, in dimension, it fits the pipe opening of the pipe 5. In order to achieve the best possible displacement force from the compressed air introduced through the pipe 5, since the compressed air constitutes the driving force for the rotor, the plate 10 is somewhat obliquely disposed with respect to the cylindrical surface of the housing as illustrated on the drawing. Complete closure of the pipe 5 is admittedly not achieved by this embodiment, however, the closure will be sufficient to achieve the desired effect.
  • the inlet for the turbulence channels in the element 6 is also indicated on the drawing.
  • the means according to the invention may be effected as illustrated on FIG. 3B.
  • the means corresponds to that on FIG. 3A but the counter-balance 11 is omitted so that the centre of gravity of the rotor is not in the axis of rotation, an eccenter effect being thus achieved which, in addition, imparts mechanical agitation.
  • the means as illustrated on FIG. 3C can be effected with a rotor without closure plate and with an uneven weight distribution of the arms of the rod element instead, so that there is a greater weight at 12. A powerful eccenter effeet and a reduced air pulsation is thus achieved.
  • a container for compressed air transport of granular material or sluggishly flowing material comprising at least one nozzle (3) arranged on the inner peripheral surface of the container (1) for introduction of compressed air, with plate-shaped element (6) provided with turbulence-producing channels connected in front of the nozzle (3), characterized in that the plate-shaped element (6) is mounted in a cylindrical housing (4) connected to the nozzle (3), that in the housing (4), between the element (6) and the end wall (8) of the housing, a rotor (9) is provided for production of vibrations, and that the compressed air is introduced into the housing through an inlet pipe (5) arranged eccentricly to the housing (4) on the peripheral surface of the housing in the area of the rotor (9).
  • the rotor is formed as one or more rod-shaped elements (9) having a closure plate (10) for the inlet pipe (5) at least at one end.
