"Container for granular and powdery goods"

The invention relates to a container for granular and dusty Well, the box-shaped frame and one or more pressure-resistant transport containers firmly inserted into them with filling and discharge openings. Such a container for dust goods has become known, its transport container consists of a cylindrical wall part with outwardly curved end walls and wherein the cylindrical wall part

underneath with distributed over its length, relatively dense successive discharge funnels and subsequent discharge openings is provided.

This known container has because of the large number of underside arranged discharge funnel with discharge openings and associated closures or other aids for removal the goods have a relatively high dead weight. In addition, this known container is relatively expensive to manufacture.

So-called inland containers have also become known, which only one lower support frame and one tiltable on it arranged, elongated cylindrical transport container together with hydraulic lifting device. These Inland containers are even more expensive to manufacture and are not approved or suitable for overseas transport.

Finally, there are also containers with built-in cylindrical ones Transport container has become known in which the transport container has an outlet opening at one axial end owns. These containers are either only suitable for the transport of liquids, di.e then without difficulties in Open the valve to flow out of the outlet opening, or but the container equipped with such a transport container must be placed on and on a special chassis

7435968 et08.78

be tilted. The recipient of the container then needs such an expensive special chassis for unloading with tilt drive. These containers are significantly further from the invention than the container mentioned at the beginning a transport container which has several discharge funnels.

Based on these known containers, the object is to be achieved to create a container for granular and especially for dust-like3 goods with a permanently inserted pressure-resistant transport container, which allows the filled goods to be unloaded in a simple manner without the addition of a tiltable special chassis ¹ and at the same time has a lower dead weight and is cheaper to manufacture than the well-known Coi.tainer with several discharge funnels.

To solve this problem it is proposed that the transport container has two conical wall parts whose facing ends of larger diameter, symmetrical to one perpendicular to the longitudinal axis of the container, are airtightly connected to each other, while the outer tapered ends are closed in a known manner by airtight end walls connected to them, the The upper surface lines of the two cones are aligned with one another, so that the outlet opening is also in the plane of symmetry, in the deepest Part of the transport container, that continues to be the bottom

of the transport container with pneumatic loosening means

j and finally the cone angle of each of the two

j conical wall parts larger than the flow angle of the

filling bulk material with pneumatic loosening.

The inventive solution to the problem thus makes use of known features, that is to say of the fact that the flow angle of the filled bulk material, i.e. the angle at which this will flow off with certainty, in the case of pneumatic Loosening is significantly reduced. Accordingly, the transport container contains such pneumatic loosening means, which are suitable for producing this effect by introducing finely divided compressed air into the material and thus fluidize it.

Through the proposal according to the invention, the transport container from two with their further openings connected to one another, to form symmetrically arranged conical wall parts, the upper surface lines of the two cones with each other align, an optimal use of space within the container frame and at the same time on the bottom of the

the bottom of the transport container, provided with air-permeable walls, hoses that are provided with compressed air be fed. Such hoses have "already proven themselves excellently in other transport containers. Also for the container according to the invention are these hoses, on the one hand because of their particularly good loosening effect and on the other hand, particularly suitable because of their robustness, transport security, lightness and their small space requirements.

Furthermore, to feed these hoses, preferably at one or even better at both ends of the transport container uses an air distribution chamber, as has been done in others Context has become known. ! This chamber, consisting of the lower part of the end wall in question, part of the floor and a partition is formed which runs obliquely to the central axis of the transport container, guides the wall connected to it The compressed air hoses. The hoses can also be provided with inserts or in a manner known per se can also be held and fixed in any other way on the bottom of the transport container.

The two conical wall parts of the transport container can either abut close together and be connected to one another, preferably be welded. Preferably the ones are conical

Wall parts but connected to one another by two cylindrical connecting rings, the edges of which are slightly angled to one another and the narrowest points of which are at the top between the two conical wall parts. With this design, a V-shaped indentation arises on the upper side of the transport container, which is characteristic of this transport container, which is relatively easy to manufacture. The two intermediate rings , ULe can be made from a cylindrical tube by inclined cutting, allow, depending on the axial length, any increase in the total length of the transport container while keeping the cone angles constant and at the same time making optimal use of the container's space.

According to the invention, two can also be placed in the frame of the container or more transport containers are used. The arrangement of two such transport containers is particularly useful, which can then be filled with different bulk goods and allow the simultaneous transport of two different Allow bulk goods to the same or different customers. It is preferably provided that the two Transport containers are arranged within the frame that their upper surface lines are aligned with one another.

In such a container with two transport containers inserted into the frame, it is preferably proposed that the The end walls of the two transport containers are curved outwards

7435961 e 5.08.76

the adjacent end walls of the two transport containers touch each other with their middle parts. On the one hand, this results in a favorable pressure resistance of the two transport containers achieved and on the other hand, by supporting the same in the axial direction, a high level of transport security of the Containers.

To the space utilization of the container for the falling When using two transport containers to increase bulk goods even further, the two transport containers are according to the invention connected to each other and have a common partition in the area of this connection. The connection can thereby preferably carried out by a cylindrical connecting piece, the partition then either on one or on the other The end of this connector is located. Such a training has the advantage of a standardized production. In that case, two completely identical transport containers are produced, one of which, however, has only one end wall and with its open end via a cylindrical connecting piece is connected to the other transport container, which is closed on both sides.

It is also proposed that the pneumatic loosening means are removably arranged in the transport container or in the transport containers. With such an

Education can be the container that is used for a transport route Dust is filled, if necessary on its way back to be filled with a liquid after the first destination Loosening agent removed and of course the corresponding feed openings for the compressed air sealed became. Above all, the removable design of the loosening means allows a reduction in the Warehousing, both for the manufacturer and for the buyer of large numbers of such containers. Namely, it can then at any time the loosening agent from a part of the container be expanded or installed and thereby these containers for the transport of dust or for the Transport of liquids can be made suitable.

The invention is explained in more detail below in exemplary embodiments with reference to the drawing. Show:
