Definitions

  • the invention relates to an outlet device of a container for dust or granular bulk material with a conical downward shape to a narrower cross section of a connecting piece for a delivery line narrowing outlet body, the outlet device or the Outlet body is reversibly connected to the container.
  • the inner funnel-shaped outlet surface air-permeable film material formed so that between the outer airtight cone wall and the inner cone wall entered Compressed air can flow into the bulk cone space and this avoids bridging or dissolves again.
  • the type of compressed air supply can be continuous or intermittent and leads to a brief shaking movement of the inner wall of the outlet cone, which continuously supports bulk material removal.
  • the inner jacket made of film material must not be arranged in this way be that a pocket formation during the compressed air-assisted bulk material removal is favored.
  • the inner film jacket is therefore firmly clamped at the top and at the lower end by means of clamping structures, which are known in various embodiments, held.
  • an outlet device the one tapered down to a narrower cross section a connecting piece for a delivery line constricting outlet, the outlet device being reversibly connected to the container and wherein a bowl insert is arranged in the outlet body is, which has an upper cantilevered edge, which in the area of The contact surface between the container and the outlet body is kept clamped becomes.
  • the bowl insert has circular openings on both sides on, with a gap in the area of the wall of the outlet body between the edge of the opening of the bowl insert and the wall of the outlet body results.
  • the wall of the bowl insert can be in relation to the wall of the Outlet body run differently, the walls themselves do not touch. So the wall of the bowl insert can be parallel to Wall of the outlet body run or tapering towards this be trained. Mixed forms with parallel and tapered Sections of the bowl insert or with sections of the Bowl insert, the different inclination angles 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 a space is formed in the bowl insert, compressed air is injected into the Outlet device initiated so that the bulk material is loosened and Bridges are broken and the bulk material can drain, whereby this process is further accelerated by the compressed air.
  • the outlet device By designing the outlet device with a gap, which is preferably 2mm and through which the compressed air in the direction of the connecting piece flows, a quick and unhindered emptying of the silo container guaranteed. Depending on the flow velocity the compressed air becomes permanent or temporary Vibration of the bowl insert creates a loosening of the bulk goods. It is advantageous if resilient Material used for the bowl insert.
  • Bulges in particular beads, can also be used in the bowl insert. that secure the gap from above and lead to the gap, be arranged, the in connection with the vibrations generated by the compressed air support emptying.
  • the bowl insert can cause a curvature of the bowl insert by applying Compressed air are caused so that when the compressed air is blown in with periodic pressure fluctuations also vibrations or a Shaking can be caused, which loosens the bulk material becomes.
  • the bowl insert led into the area of the outlet of the outlet body, the Equip the corresponding opening of the bowl insert with a nozzle can be.
  • the bowl insert is also a penetrating wall tubular body arranged on the appropriate means on Bowl insert is held.
  • the tubular body is on the inside of the bowl insert closed at the end, but laterally Holes or the like are provided. Above these holes, the tubular body a lip-like annular body made of rubber o. Like., The outer edge of which rests on the bowl insert and so one Cavity into which the holes in the tubular body open forms.
  • compressed air enters the gap between the bowl insert and the outlet body, from where it is pressed into the tubular body and into the through the lip-like annular body.
  • the compressed air lifts the rubber lip off, so that a shaking movement results that the bulk material loosened up.
  • One or more of these tubular bodies can be in the bowl insert may be provided.
  • the bowl insert can be used with a coarse-mesh mat, preferably made of stainless steel, aluminum or the like his.
  • This mat can be made with strips, preferably also made of stainless steel or the like. Reinforced, holes being passed through the strips, that correspond to corresponding holes in the bowl insert.
  • the holes lying one above the other can also be provided with a rivet that connects the mat and the bowl insert, whereby an opening remains in the middle of the rivet.
  • the mat can also consist of very coarse-mesh fabric, whereby then openings are provided in the bowl insert, which differ from extend downwards below and preferably narrow downwards, stripes are not necessary for reinforcement.
  • the outlet device is preferably connected to the silo container via a Flange using eye or hook screws or a quick release device connected.
  • a ring seal arranged, which also in one on one of the edges circumferential groove can be inserted, the ring seal of course must protrude for sealing.
  • the ring seal acts on it also the cantilevered edge of the bowl insert and fixes it in addition it is also possible that in the two opposite The edges of the ring seals are inserted in the corresponding grooves.
  • the effect of the outlet device according to the invention is optimized in such a way that the emptying of the Bulk goods are easily possible.
  • the bowl insert is preferably made of stainless steel or aluminum manufactured. But plastics are also suitable that have a sufficient mechanical strength and abrasion resistance. Fiber-reinforced and coated plastics are also used can by the surface coating a resistant and maintain low-friction surface. Even composites from different Materials can be used to differentiate Requirements for mechanical strength and resistance to Abrasion.
  • the outlet device according to the invention can be advantageously also by retrofitting a bowl insert in existing ones Create silo containers because this is only in the flange between containers and outlet body must be clamped. There are no additional ones Fastening points for the bowl insert necessary.
  • the bowl insert can also be completely used for certain applications take out, so that no objects at all Material flow.
  • the simple structural design also allows a very simple one Cleaning, especially in the food and chemical sectors is of great importance.
  • the outlet device 100 is used, for example, both for stationary silo containers as well as for such containers, the body part of a vehicle are used. Such containers have one or more of those shown Outlet devices 100.
  • the silo container body partially shown 10 is connected to a funnel-shaped outlet body 11, which together with a bowl insert arranged in its interior 12 13 forms the outlet device 100.
