material residues sometimes stick in and / or on the sieve, which means that the internal cleaning of the container is extremely time-consuming required if a different type of material is to be added after emptying.

Instead of a sieve, a gas nozzle has recently been installed in the bottom area of the container and this one Gas nozzle directed in the direction towards the container outlet. In this way, there is no need for clinging Material required internal cleaning, but the known nozzles allow an even distribution of the supplied Gas does not, because the gas can only be supplied in one or two places, which helps to maintain a uniform distributed fluidizing effect is quite inadequate.

The object of the present invention is to remedy these drawbacks and to provide an arrangement with simple Means preventing any material residue remaining in the container and using the same simple means . Such an inevitable guidance of the fluidizing gas allows the latter z. B. is evenly distributed around a material flow and this in the flow direction influenced towards an outlet.

This object is achieved in that the Container with a region having at least one opening, protruding into at least one flow part, the one Represents connection between the interior of the container and each outlet, the protruding into the flow part Area of the container and / or at least one element provided in connection with the area mentioned the flow part at least one guide column for out the gas supply device forms received gas flows.

Invention claimed.

The invention is explained in more detail below with reference to the accompanying drawings, in which:

1 shows in section a transport container with a device according to the invention;

Fig. 2 shows, on a slightly larger scale, the bottom part of the container with the device according to the invention ; and

3 and 4 the bottom parts of containers with alternative designs of the device according to the invention.

Fig. 1 shows a container 1 for granular and / or powdery Material, e.g. B. cement, flour or fodder. The container 1, for example on a transport vehicle is set up, has a substantially spherical shape and is closable by means of a lid 3 at the top Filling opening 2 provided. The container is tapered downwards in the direction towards at least one outlet 4, which Has a bent outlet pipe 5 or the like. A gas supply device 6 is used to fluidize the bulk material provided, through which a gas, preferably air, is to be supplied under pressure to the material in the area of the outlet4. The use of such fluidization is intended to facilitate the leakage of the goods.

The parts of the fluidization device located inside the container 1 (e.g. sieves, intermediate floors, screens) either cause the remaining material after emptying remains in or on these parts - a removal of this remaining material requires an elaborate internal process Cleaning of the container - or that the gas is fed in at a few points, which becomes uneven and intermittent brings effective fluidization with it.

According to the invention, this problem is in principle thereby eliminated eliminates that the container 1 with a part la, which has at least one opening Ib, in at least one passage part 7 opens, which represents a connection between the interior of the container 1 and each outlet 4, the in the passage part 7 opening part la of the container 1 and / or at least one element 8 arranged in connection with this part la and having at least one passage part 7 Guide gaps 9 for the gas feed device 6 received gas streams forms.

By fulfilling these conditions, a stable construction is obtained with extremely simple means Emptying the container 1 in no way can hold back bulk material residues and also one too different For purposes of extremely favorable guidance of the gas supplied from the gas supply device 6 is allowed.

In most cases it is sufficient to guide the gas in such a way that that it is distributed as evenly as possible around the "passage" along which the material flows to the outlet. According to the invention this is made possible in that the guide gap 9 runs around the passage path, the Guide column 9 on the one hand from the gas supply device 6 gas receives through openings in the Passage part, on the other hand, essentially in the direction after the outlet 4 releases gas.

As a result, the gas is in the form of a pressure ring surrounding the "flow path" (circular or otherwise shaped, depending on the shape of the container 1 and the flow part 7) delivered, which is essentially uniform and in the main acts in the direction of flow of the bulk material.

In order to have separate cover screens for shielding the openings 10 of To be able to dispense with the above-mentioned pass-through path, according to the invention, the openings 10 from the inside through the one

Part la of the container 1 is covered, which protrudes into the passage part 7, and / or from the inside through the element 8 *

The production of the arrangement according to the invention is then particularly simple if the guide gap 9 is formed by the fact that the outside of the passage part 7 protruding part la of the container and the inside of the area 7a of the passage part located outside this 7 run completely or partially at a distance from one another

Following the principles indicated above, various alternative embodiments can be implemented, of which some are shown on the accompanying drawings. So z. B. the outflow part 7 with one end area by a spacer 11 (z- »B. a spacer ring, if the lower Part of the container 1 is conical) in which in the flow part "7 protruding area la of the container 1 can be rigidly attached, said protruding area la and outside This area located parts 7a of the flow part 7 extend substantially parallel to each other and a guide gap 9 limit with a substantially uniform width. As a result, the gas flow mentioned has a width that is approximately the same as that of the guide gaps 9, which can often be advantageous.

Instead, the flow part 7 can have an end region that protruding into the flow part 7 area la of the container 1 be attached directly, this protruding area la of the container 1 and the outside of this area located area 7a of the flow part 7 obliquely to each other run and thereby form a guide gap 9 with an increasing or decreasing width after the outlet 4. This enables gas streams to be emitted which are wider or narrower than the guide gaps 9.

In certain cases it may be useful to use a special element 8 to create the guide gaps 9,

that in the extension of the container area la beschraclr is. The element 8 can be designed in various ways and preferably consists of a ring (circular or shaped differently), which is arranged immediately following the area la. The ring is preferably made made of elastic material, e.g. B. rubber or the like., And is firmly glued to the inside of the flow part 7 or Vulcanized., Furthermore, the ring has a region 8a, which the protruding into the flow part 7 region la des Container 1 is closest and which has the same or a slightly smaller thickness than this area la, after which the ring 8 merges into a thinner area 8b which runs freely within the openings 10. This refinement According to the ring, it is prevented that bulk material remains in the container 1 by "clinging" to the ring. Besides that an appropriate guide gap 9 is formed, and the area 8b ensures that the connection of the openings 10 with the bulk material in the container 1 is completely interrupted when the supply of pressurized gas is stopped - the gap is namely thereby locked so that the bulk material from the inside presses the area 8b and firmly against the inside of the flow part 7 presses.

In order to ensure that the parts of the gas supply device also have the necessary gas distribution effect and a simple design have, this device 6 has a feed pipe 6a, to which the flow part 7 forms a wall, this wall having openings 10 which connect the interior of the tube 6 a with the guide gap 9.

The previous description has not dealt with details that are inherent in the construction according to the invention belong, but are self-evident to a person skilled in the art. So z. B. is the source for generating the compressed gas (preferably the Compressed air) is not shown, but only part of a pipe 6b extending therefrom to the pipe 6a. Besides that A fastening flange 7b of the flow part is shown

With this fastening flange 7b is through (not shown Bolts a fastening flange 5a of the tube 5 firmly connected, whereby this pipe is thus held in place.

This description and the accompanying drawings are intended to illustrate the measures according to the invention only by way of example and without Explain limitations. Of course it is z. B. not necessary that the lower part of the container 1 and the Flow part 7 are conical, but their shapes can be varied within wide limits. Also needs the protruding into the flow part 7 region la of the container 1 not be closed in a ring, but it can z. B. consist of adjacent, tongue-like screens. Furthermore, the guide column 9 by a part of the Area la and an element 8 attached to this part are formed. In other words, shaping and mutual Positions of parts of the device according to the invention can vary within the scope of the claims.
