Definitions

  • the invention relates to a discharge device for a container for dusty or granular bulk material with a conically tapered downwards for a delivery line outlet body which is connected by means of a flange to the container, with a consisting of an air-permeable material ventilation insert whose upper side is fixed to the flange , With a gap between the ventilation insert and the outlet body, wherein in the space to increase the flow and lubricity of the bulk material compressed air can be pressed.
  • the inner funnel-shaped outlet surface is usually formed from air-permeable film material, so that compressed air introduced between the outer impermeable cone wall and the inner cone wall can flow into the bulk material cone space, thereby avoiding bridging or being dissolved again.
  • the inner film jacket is clamped at the top and at the bottom by means of clamping structures, which in various embodiments are known held.
  • clamping structures which in various embodiments are known held.
  • disadvantages are also associated with these clamping constructions, which partially offset the advantage of minimizing friction when bulk material is emptied.
  • the means required for clamping are sometimes arranged in the interior of the cone and hinders the outflowing bulk material in the way.
  • the design effort for the clamping device is relatively high, which also has a negative effect on the maintenance.
  • a discharge for intended for the transport of bulk containers consisting of a funnel-shaped by means of a flange at its upper edge with the container and with its lower edge connectable to a feed line connecting piece and arranged in this ventilation insert. Compressed air can be injected between the connecting piece and the ventilation insert in order to increase the lubricity of the bulk material.
  • the ventilation insert is made of a non-rigid ventilation cloth made of a polyester or a wire mesh.
  • a discharge device for a container with a downwardly narrowing outlet body, in which a bowl insert is arranged.
  • the bowl insert is held in its upper region between the container and the outlet body, wherein at its lower edge there is a circumferential gap to the wall of the outlet body. Between the wall of the outlet body and the wall of the bowl insert, a gap is formed, is introduced into the compressed air via a nozzle.
  • the invention provides that a first and a second nozzle are arranged on the outlet body in the region of the intermediate space, wherein through the first nozzle compressed air and through the second nozzle a fluid is conductive, whereby a flushing and / or cleaning of the outlet device, in particular of the intermediate space and the ventilation insert is feasible.
  • the advantage of the outlet device according to the invention is that the ventilation insert is particularly effective for material loosening of the bulk material, wherein compressed air is pressed into the intermediate space through the first nozzle. As a result, the bulk material sliding out of the container into the outlet device is loosened so that it can reliably drain down into the delivery line.
  • the invention When changing the bulk material, the invention further offers the significant advantage that due to the integrated flushing and / or cleaning option, the outlet device no longer has to be completely dismantled.

  • the check valve inter alia, ensures that not pressed into the intermediate space air flows back through the nozzle.
  • a vibration of the ventilation insert is generated, which causes a loosening of the bulk material, so that this quickly and smoothly from the outlet device is applied.
  • the vibration of the ventilation insert which is preferably carried out self-supporting, can be further promoted if the material of the ventilation insert is resilient.
  • the lower side of the ventilation insert is formed with a plurality of spacer elements, which are arranged on the wall of the outlet body. Between the spacer elements, the lower side of the ventilation insert in each case has a gap to the wall of the outlet body, through which the injected air flows in the direction of the narrowing outlet body, whereby a rapid and unhindered emptying of the container is ensured.
  • the gap is preferably 2mm
  • the spacer elements can be designed as bulges, in particular as beads, which secure the gap from above and are arranged leading to the gap.
  • the spacer elements advantageously assist the emptying of the container in conjunction with the vibrations generated by the compressed air.
  • the outlet device according to the invention can also be created by retrofitting the ventilation insert in existing silo containers, since this only has to be fastened in the flange between the container and the outlet body.
  • the first and the second nozzles are furthermore arranged without great effort in the outlet body.

  • the outlet device can offer it in a design alternative, at least three nozzles circumferentially evenly distributed on the outlet body.
  • the nozzles are on the outside of the outlet body, which are arranged to each other at the same height. This means that the said nozzles to the outlet opening of the outlet device through which the bulk material leaves the container, have the same distance, With the use of three nozzles, it is advisable to arrange them offset by 120 ° to each other, thus uniform distribution of the Compressed air and / or the fluid to achieve in the outlet device.
  • four nozzles may be arranged on the outlet body, which are positioned offset from one another by 90 °.
  • connection unit expediently comprises a fluid connection part and an air connection part.
  • the connection unit can have a feed line and a distribution line, wherein the feed line opens into the distribution line.
  • the common supply line distributed line
  • the connection unit for the fluid connection and the compressed air connection and the downstream distribution line dividing into at least two connecting stubs improves both the discharge process and the cleaning process.
  • a fluid-compressed air mixture for flushing and / or cleaning can be introduced through the nozzles.
  • the flushing process can be achieved not only by the fluid, in particular by the water, but by a fluid-compressed air mixture.
  • a cleaning fluid is formed as a fluid-air mixture that meets under increased pressure on the ventilation insert and this cleans quickly and completely.
  • connection unit is designed as a Y-shaped line, which is formed by a feed line opening into the distribution line, wherein the distribution line is connected at its free ends directly or indirectly with the nozzle.
