  • the wall of the bowl insert can in relation to the wall of the Outlet body run variously, the walls themselves do not touch.
  • Also mixed forms with parallel and tapered Sections of the bowl insert or sections of the Bowl insert, the different angles of inclination to the wall the outlet device, are possible according to the invention.
  • a nozzle for compressed air in the area of the outlet body is provided, where between the walls of the outlet body and the bowl insert a space is formed, compressed air is in the Launch device initiated, so that the bulk material loosened and Bridges are broken up and the bulk material can drain, with This process is additionally accelerated by the compressed air.
  • the outlet device Due to the configuration of the outlet device with a gap, preferably 2mm and through which the compressed air in the direction of the connecting piece flows, is a quick and unhindered emptying of the silo container ensured.
  • the compressed air is a permanent or short-term Oscillation of the bowl insert generates, which additionally a loosening of the bulk material causes. It is advantageous if elastic Material is used for the bowl insert.
  • the bowl insert can also bulges, in particular beads, which secure the gap from above and lead to the gap, be arranged in conjunction with the vibrations generated by the compressed air support emptying.
  • the bowl insert led into the region of the outlet of the outlet body, wherein the corresponding opening of the bowl insert provided with a nozzle can be.
  • the bowl insert is also a wall penetrating arranged tubular body, which via corresponding means on Bowl insert is held.
  • the tubular body is on the inside the bowl insert closed at the end, however, the side Holes o. The like. Are provided. Above these holes, the tubular body a lip-like annular body made of rubber o. Like. On whose outer edge rests on the bowl insert and so on Cavity into which the holes of the tubular body open forms.
  • a coarse mesh mat preferably made of stainless steel, aluminum o. The like. Occupied be.
  • This mat can be made with strips, preferably also made of stainless steel o. Be like. Strengthened, which are guided through the strip holes, which correspond with corresponding holes in the bowl insert.
  • the Overlying holes can also be provided with a rivet be, which connects the mat and the bowl insert, wherein an opening is preserved in the middle of the rivet.
  • the mat can also consist of very coarse-meshed fabric, wherein then openings are provided in the bowl insert, extending from extending upward at the bottom and preferably narrowing towards below, Strips are not necessary for reinforcement.
  • the outlet device is preferably connected to the silo container via a Flange by eye or hook screws or a quick-release device connected.
  • ring seal arranged in addition to one on one of the edges circumferential groove can be inserted, the ring seal of course must stand out for sealing.
  • the ring seal acts on it also the cantilever edge of the bowl insert and fix this In addition It is also possible that in the two opposite Rims ring seals are inserted into corresponding grooves.
  • the effect of the outlet device according to the invention is optimized in such a way that even with angled connecting pieces the emptying of the Bulk material is easily possible.
  • the bowl insert is preferably made of stainless steel or aluminum manufactured. But there are also suitable plastics which have a sufficient mechanical strength and abrasion resistance, whereby also fiber-reinforced and coated plastics are used can, which by the surface treatment a resistant and obtained low-friction surface. Also composites from different Materials can be used to differentiate Requirements for mechanical strength and resistance to Abrasion meet.
  • outlet device can be advantageously also by retrofitting a bowl insert in existing Silo containers create, as this only in the flange between container and outlet body must be clamped. There are no additional ones Attachment points necessary for the bowl insert.
  • spacers which also on the bowl insert can be fixed.
  • the bowl insert can be completely take out so that no objects at all Material flow are located.
  • the simple structural design also allows a very simple Cleaning, especially in the food and chemical sector of great importance.
  • the outlet device 100 for example, both for stationary silo container as well as for such containers, the body part of a vehicle are used. Such containers have one or more of the illustrated Outlet devices 100.
