Definitions

  • the subject of the invention is a device for simultaneously projecting a liquid or pasty product and a pulverulent, granular or fibrous load to produce a "reinforced" plastic wall covering or coating, in which the product is pumped to an organ. of centrifugal projection with central feed.
  • Devices of this type which carry out the spraying of a plaster, by a process known as "guniting", in which the plaster can be a mortar, plaster or a resin setting on the projected surface Simultaneously we can have a projecting a powdery, grainy or fibrous filler, in particular a glass fiber filler.
  • a coating of aminoplast resin sprayed with shredded glass fibers is commonly used.
  • the applications of the invention will not be limited to this particular application, nor to the products mentioned.
  • the object of the invention is to propose a new device which is easier to use than the known devices, which can be used conveniently in excavations, even those which are inaccessible or difficult to access for a man, and therefore operable from a distance and operating safely, which requires no risk of blockage.
  • the object of the invention is achieved, by a device of the type described at the beginning, thanks to the fact that it comprises, for the projection of the product, a turnstile with its central feeding means, and, for the projection of the load pulverulent, a centrifugal wheel and a means of supplying the load to the centrifugal wheel, the turnstile and the centrifugal wheel being advantageously mounted on the same shaft close to each other.
  • the means for feeding the load to the centrifuge wheel is a pneumatic conveying duct which opens into the axis of the centrifuge wheel opposite the side at the turn 'niquet and the centrifuge wheel is of generally conical shape from the top directed towards the discharge end of the pneumatic transport pipe.
  • the shaft of the turnstile and the centrifugal wheel to be driven by a motor.
  • the reaction force of the product ejected at the end of the branches of the turnstile will be insufficient to set it in motion.
  • the device of the invention comprises means of support in translation on the walls, which means advantageously serve as centering means and cause that the axis of the turnstile and the direction of translation are parallel.
  • the speed of coating of the constituent material will be improved.
  • the load by orienting the device so that the centrifugal wheel is upstream aerating relative to the turnstile.
  • a housing 1 consists of a sealed rolling bearing with two ball bearings 2 and 3, provided in the vicinity of its ends, for a shaft 4 which passes right through it.
  • the shaft 4 carries a hub 13 traversed by tubes 6 at regular angular distances, for example two tubes at 180 ° from one another, substantially radial from the hub, then slightly bent , open at their ends remote from the axis and communicating on the axis with a central channel provided in the axis of the shaft 4 and extending to an annular groove 8 of the shaft 4 delimiting an annular chamber 9 between shaft and housing.
  • a transverse channel 10 places the central channel 7 in communication with the annular chamber 8, into which a channel 11 passes through the housing 1, itself connectable to a supply pipe 12.
  • the assembly described so far constitutes a turnstile 20 with central feed for the projection of the product, which can be brought under pressure by the pipe 12.
  • the hub 13 carries, on a side opposite the shaft 4, a short shaft 14 of axis extending the axis of the shaft 4 and carrying at its end a wheel 15 in the form of an obtuse cone 16 whose apex 17 is directed opposite the turnstile.
  • a pipe 18 opens into the axis of the wheel 15 near the apex 17 of the cone 16.
  • the pipe 18 is a pneumatic transport pipe for supplying previously shredded glass fibers, or other suitable material which can be transported pneumatically, from a storage hopper 19 (FIG. 3) by suction in a pipe 21 by means of an ejector 22 supplied with air compressed by a pipe 23.
  • the shaft 4 is shaped as a cone 24 for fixing to a motor 38 constituted by a rotary perforator 25 with compressed air supplied with compressed air by a pipe 37.
  • a central tubular element 27 coaxial with the turnstile 20 is connected to the frame 26 and is arranged so as to release the projection planes of the turnstile and of the centrifugal wheel.
  • FIG. 1 shows the central tubular element opposite the casing and the perforator with respect to the turnstile, but it could just as easily surround the casing and the perforator, provided that the projection planes are clear.
  • the central tubular element 27 carries three skis 28 mounted on springs 29 to center the entire device in an excavation.
  • the tubular element 28 ends in a cone 29 and a ring 30 for coupling the entire device to a hauling cable 31.
  • the frame 26 also carries a guide slide 32 for the return strand 33 of the hauling cable 31.
  • FIG 3 there is shown an application to the remote spraying of a resin reinforced with glass fibers to consolidate the walls of a borehole 40 of 600 mm in coal ground and simultaneously prevent oxidation of the massive in coal areas.
  • the purpose of drilling the borehole 40 was to improve the ventilation in a tracing track 41 from a gallery 42 of a neighborhood in operation and to serve emergency exit.
  • a winch 43 was installed in the tracing 41 for an endless cable 34, 33, 31 returned by a pulley 35 installed in the gallery 42.
  • the device of the invention is hauled into the borehole , thanks to the ring 30.
  • the turnstile is supplied with resin from a pumping station 36 by the pipe 12 and the centrifugal wheel is supplied with shredded glass fibers as has already been exposed.
  • the survey also includes one or more compressed air pipes (23, 37), which have not been shown in FIG. 3 for the simplification of the drawings, but which are of the usual type in mines.
