Definitions

  • the invention relates to a device for the metered discharge of bulk material from a container according to the preamble of claim 1.
  • the scraper running between the funnel wall and the film causes the latter to move, which in turn causes a spiral vortex in the bulk material to be discharged.
  • the scraper does not come into contact with the product itself.
  • the loosening of the product is brought about in a gentle way by the film applied by the stripper. As a result, erosion, damage and destruction of the bulk material grains are avoided. Gluing of the latter and thus the formation of bulk material bridges inside the funnel can no longer occur.
  • the funnel-shaped film ensures an undisturbed material flow because there are no mechanical parts inside.
  • the film also prevents contamination from various contaminating substances, such as gear oil, etc.
  • the film is a cheap wear item and can be replaced without specialist knowledge.
  • the chemical nature of the plastic from which the film is made depends on the intended use.
  • the discharge device according to the invention can also for handling bulk goods of the highest standard, such as pharmaceuticals (antibiotics, blood plasma, etc.) or raw materials of high-purity technology such as heavy and rare metals for sintering technology, metal oxides for piezoelectric, fiber optics, metal chlorides for the nuclear industry, etc.
  • pharmaceuticals antibiotics, blood plasma, etc.
  • raw materials of high-purity technology such as heavy and rare metals for sintering technology, metal oxides for piezoelectric, fiber optics, metal chlorides for the nuclear industry, etc.
  • the invention also relates to the use of the above-described devices for the simultaneous discharge of bulk material from several silos of a mixer tap in order to produce a product mixture from granular components.
  • the tapered lower section of the funnel-shaped film of each discharge device which adjoins the associated hollow cylindrical outlet, is not covered by the fixed outer funnel. It forms an oblique cone with a central axis pointing in the direction of a mixing device, so that the central axes of all oblique cones intersect in the entrance of the mixing device.
  • each wiper section having the shape of an inclined cone can be associated with a wiper running on a circular path, which acts on the film only along part of its circular path.
  • the device according to the invention for discharging bulk material from a container for example a silo S, comprises a hopper 1 provided after an opening in the silo bottom, at least one scraper 2 arranged in the inner surface of the hopper and a slide 3 for opening, regulating and closing the mouth of a hollow cylindrical outlet 4 adjoining the tapered lower funnel end.
  • the scraper 2 is fastened in a manner known per se to an annular body 5 forming the wall of the hollow cylindrical outlet 4, which is rotatably mounted in a gear box 6 and anchored to the same Electric motor 7 is driven.
  • a film 8 is also arranged in a funnel-shaped manner, at the beginning at the edge of the opening of the silo bottom between it and the flange 9 of the large-diameter funnel entrance fastened to it and at the exit between the edge of the mouth of the hollow cylindrical outlet 4 and the flange 10 of a pipe 11 provided for the removal of material is clamped.
  • the film 8 is expediently made of plastic and composed of several layers of the same. Depending on the intended use, the film 8 can be made of a composite material made of natural material and plastic and also have a gas-permeable quality.
  • the funnel-like film 8 can initially only be provided to extend a short distance into the hollow cylindrical outlet 4.
  • the funnel-shaped film 8 can alternatively be formed in a scale-like manner from fabric and / or plastic strips 12 which overlap along their edges running in the direction of the generatrix of the funnel jacket surface, the overlap being oriented in the direction of rotation A of the stripper 2 (see arrow A ) and the overlapping edges are each reinforced with a stiffening rod 13 (see. Fig. 3a and b).
  • a still further embodiment of the invention provides between the inner surface of the fixed outer funnel 1 and the funnel-shaped film 8 instead of rotating wipers 2, a number of activation bodies 14 which can be acted upon by a pressure medium in a symmetrical distribution.
  • the latter can be provided particularly expediently in the form of hoses which can be actuated in a rotating sequence by means of compressed air pulses (cf. FIGS. 4 a and b).
  • FIG. 5 illustrates a possible use of devices according to the invention for the simultaneous discharge of bulk material from three silos S of a so-called mixer tap B to create a product mixture from granular components.
  • the mixer tap B could of course also be composed of a different number of silos.
  • the lower section of the funnel-shaped film 8 of each discharge device which tapers to the associated hollow cylindrical outlet 4 and is not covered by the fixed outer funnel 1.
  • said film sections each form an oblique cone with a central axis pointing in the direction of a mixing device 15, so that the central axes of all the oblique cones intersect at the entrance to the mixing device 15.
  • a scraper 2 can then be assigned to each such section of film in the form of an oblique cone, which rotates on a circular path and only acts on the film 8 along part of the same.
