Definitions

  • the invention relates to a method and a device for the continuous production and simultaneous delivery of a water and hydraulically bindable solid material in a homogeneous mixture containing pumpable building material mixture such as plastering mortar.
  • Methods and devices for producing a pumpable mortar for example for plastering walls or ceilings, are known. These are often designed to carry out a discontinuous mode of operation, ie the device has a separate mixing device, in which the mixture is prepared and this is then poured into a delivery container with a thick material pump flanged on from the mixing device and conveyed from there to the construction site.
  • discontinuously operating systems consist, inter alia, in that a prolonged interruption between the preparation of the mixture and its further processing can result in harmful segregation.
  • discontinuous operation has fundamental disadvantages compared to a continuous mode of operation, because interruptions in processing occur between the individual batches, which lead to losses in working hours and productivity and thus unnecessarily burden the construction costs.
  • the invention has for its object to provide a method and an apparatus of the type mentioned in the preamble of claim 1, with which the difficulties and technical limits mentioned are overcome and which a continuous production of a mixture free of air inclusions with the smallest possible volume and weight of Device allows.
  • a device for carrying out the method is characterized by the features a) to g) specified in the characterizing part of claim 3.
  • the device shown in the figure has a mixing tube (1) which is circular in cross section and in the interior of which a mixing screw (3) with worm spirals (4) is arranged which rotates around a drive shaft (2).
  • a mixing tube (1) which is circular in cross section and in the interior of which a mixing screw (3) with worm spirals (4) is arranged which rotates around a drive shaft (2).
  • a feed opening (5) Approximately half the length of the mixing tube (1) has a feed opening (5) and within it a metering device (6) for metering solids.
  • a concentric water injection device (7) rotating in a peripheral arrangement inside the mixing tube (1).
  • This consists of an annular hollow profile welded to the inner wall of the mixing tube (1) in a watertight manner and, in accordance with the exemplary embodiment shown, has an angular cross section.
  • the hollow profile can also have a semicircular or U-shaped or similar cross section.
  • Distributed nozzle bores (19) are located on the circumference of the hollow profile, from which the mixing water for mashing the solid is injected under pressure in concentric jets into the solid.
  • the water injection device (7) has a water connection (24) which is connected to a pressurized water source via a line (not shown) with an adjustable metering device.
  • a breather (9) At the drive end (8) of the mixing screw (3) in the upper area of the mixing tube (1) there is a breather (9).
  • the mixing device at the output end (10) on the mixing screw (3) has a baffle plate (11) which releases a peripheral annular gap (13) between the inner wall of the mixing tube 1 and its outer edge (12).
  • the mixing tube (1) has a concentric discharge opening at a distance from the baffle plate (11) in the discharge direction (14) having a comparatively smaller diameter than the baffle plate (11), to which the housing (15) of a thick material kneading pump (16) connects.
  • the drive shaft (2) of the mixing screw (3) is rotatably connected to the rotor (18) of the pump (16) via a coupling (17).
  • the solids feed opening (5) very advantageously has a collar (20) with a flange (21) for the substructure on a solids silo container with intermediate arrangement of the solids metering device (6).
  • This is advantageously designed as a rotary valve.
  • the coupling (17) between the drive shaft (2) and the pump rotor (18) is designed as an elastic coupling with coupling intermediate members made of elastic material such as rubber or plastic.
  • the coupling (17) can be equipped with an overload safety device, for example with a shear pin safety device (22).
  • the mixing screw (3) can also be at least partially equipped with mixing paddles instead of part or all of its screw turns (4). Further alternative configurations relate to the position of the mixing tube (1). This can either be arranged with a vertical axis (yy), as shown, or also with a horizontal axis.
  • the device according to the invention is suitable with great advantage for fully automatic, continuous operation for the production and simultaneous delivery of water and hydraulically bindable solid in a homogeneous mixture containing pumpable building material mixture such as plastering mortar.
  • Its special design and mode of operation according to the invention ensures that no air inclusions are conveyed during this continuous operation, which enables a completely undisturbed, uniform application of the cleaning material to the construction site while overcoming the difficulties that existed to date.
  • the device is uncomplicated, requires only a comparatively small construction volume and light weight and is distinguished by a high degree of reliability. In this respect, the invention optimally fulfills the task set out above.
