Definitions

  • the present invention relates to a device for adding air, in particular conveying air, powdery solids, liquids or their mixtures into the conveying stream of shotcrete lines at predetermined addition points, with an annular insert part which can be inserted into the conveying line, with an inlet channel opening into an annular chamber of the insert part and several the annular chamber towards the flow flow outlet channels.
  • the ring chamber acts as a swirl or circulation chamber regardless of the material supplied, which ensures the desired regular distribution of the material across all the outlet channels leading to the internal bore and thus to the flow rate of the shotcrete line. Since there is no actual congestion, the material circulating in the annular chamber also prevents the inlet openings of the distribution channels from becoming blocked.
  • the material to be added is fed uniformly into the flow.
  • Devices according to the invention can be installed at all or selected addition points in a shotcrete line (for example for all materials to be added separately or only for powdered addition materials).
  • FIG. 3 shows an addition device 1 according to the invention, which is used, for example, to add a powdery material.
  • the device 1 is installed in a shotcrete line. Compressed air and possibly a liquid (for example water) are added in this line on the right-hand side and the delivery flow is conveyed via the pump hose 2 to the left to a spray gun 3 and discharged. Shortly before the gun 3, a desired powder is added via a further addition device 1.
  • the addition device 1 is designed as an insert and, in addition to connecting pipe pieces 4, 5, has an annular base body 6.
  • the pipe sections 4, 5 are flanged to the base body 6.
  • a circumferential annular chamber 7 Arranged in the base body 6 is a circumferential annular chamber 7, from which, viewed in the direction of conveyance of the flow of flow, discharge obliquely into the central inner bore 8 of the base body 6 leading outlet channels 9 which are distributed uniformly over the circumference.
  • An inlet channel 10 for the material to be added opens tangentially into the annular chamber 7. Thanks to this constructive measure, the annular chamber 7 acts as a swirl or circulation chamber, the medium (air, powder, liquid or mixtures thereof) that circulates therein regularly and absolutely regularly on all outlet channels 9 is distributed. As a result, the medium is added evenly to all outlet channels 9 without risk of clogging and thus evenly into the delivery flow in the inner bore 8.
