Abstract

baggy Container (1) for storage and delivery of bulk material, in particular fuel pellets, having a withdrawal point (8) at the bottom (10) or near the bottom (10) of the container (1), characterized in that the bag-like container (1) at least in a section (9) facing the bottom (10) made of an air-impermeable material and two tarpaulin layers (6, 12), which at the upper end (4) of the floor facing Section (9) and sealing around the removal point (8) are connected, wherein for lifting the inner tarpaulin layer (6) of the outer tarpaulin layer (12) in one of the tarpaulin layers (12) an inlet opening (7) for a pressure medium is provided.

Description

The The invention relates to a bag-like container for storage and delivery of bulk material, in particular fuel pellets, with a sampling point on the ground or near the Bottom of the container.

It is known bulk material, such as. B. fuel pellets, store in bunker rooms and from there as needed to remove from a sampling point. The removal takes place via screw conveyors, suction devices or other known devices. The problem here is the complete emptying of the bunker room and the removal of bulk material, if only small amounts of bulk material are in the bunker room. To solve this problem, it is known to bevel the floor of the bunker room at the expense of the capacity of the bunker room. To use the full capacity, it is from the AT 6866 U known to fit into the room a tarpaulin, which can be raised to empty the bunker room with compressed air, so that form to the sampling point inclined bottom surfaces. This emptying system must be exactly adapted to the bunker room size and thus represents an expensive one-off production.

Further silosacks are known for bulk goods that be hung at their upper edges or corners and whose bottom is sewn in a funnel shape. Such But silos have a bad relationship from capacity to space. Furthermore, this requires high weight good materials and workmanship both at the bag as well as the frame.

task The present invention is to provide a container for bulk goods, the standard can be produced and a complete emptying with consistent Removal quantity guaranteed and still a good relationship between capacity and space requirements.

The The object of the invention is achieved by a bag-like Container of the type mentioned, the at least in a floor facing portion of an air-impermeable material and two tarpaulins exist, which at the upper end of the floor facing Section and sealingly connected to each other are, wherein for lifting the inner tarpaulin of the outer Planned position in one of the tarpaulin layers an entrance opening is provided for a print medium.

in the full condition there is no pressure medium between the tarpaulins and the volume of the container can be fully utilized become. The weight of the bulk material rests on the floor of the room, in which the container is placed. The dimensions of the Containers do not have to match the dimensions of the Space, even if it seems necessary, the most suitable of several mass-produced Variants (different heights and widths) to choose. However, the container according to the invention can can also be arranged free-standing in a large room. Is only little more bulk in the container, will a printing medium, e.g. B. compressed air, fed and form it sloping floor surfaces over which the remaining bulk material flow to the sampling point can.

Preferably the two tarpaulins are welded together, in particular by a hot air or high frequency welding, to ensure the tightness.

Of the Container can be stiffened along its upper edges, to increase stability and a collapse to prevent the bag-like container during removal.

alternative or additionally, the container may be at its upper Corners and / or along its upper edges loops for attachment on one or more hooks or racks to the side Increase stability.

After all the container can be closed at the top to avoid dust be and have a filling opening.

In In the accompanying drawings is an inventive bag-shaped container shown. Show it

1 a side view and

2 an oblique view of the container.

The bag-like container 1 exists in its upper area 2 from a material known for such bulk bags, e.g. B. from "Trevira" ^® Trevira GmbH. At the upper corners are suspension loops 3 provided, but not the full weight of the filled bulk material 11 carry, but only the lateral stability secure. Above is the container 1 closed and has a filling opening 5 on. Along the line 4 is the bag material with two tarpaulin layers 6 . 12 that run along its upper edge and around a pick-up point 8th welded together, sewn. In one of the planned situations 12 is an entrance opening 7 provided for a pressure medium through which the lower section 9 of the container 1 can be inflated, so that oblique, to the sampling point 8th inclined surfaces give, over which the remaining bulk material 11 to one at the sampling point 8th located Absaugsonde can flow. Instead of a suction probe that can Bulk material also via a screw in the ground 10 or at the bottom 9 be removed from a side wall.
