DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for filling transportable vessels.
It is necessary to fill vessels with flowable materials in free fall, especially in in-plant systems, in order to make it possible to convey the materials necessary for production quickly from a central storage point to the individual processing stations. It is also necessary to fill transportable vessels in free fall from a supply container in other large transport systems, for example in the agricultural fodder industry. In such systems, it is important to convey the free-falling flowable material through suitable hoses, in order to prevent splashing, the generation of dust and stray emissions. It is difficult, in the known systems, to adjust the height exactly between the discharge point from the supply store and the filler socket of the transportable vessel, and when flexible hoses are used, the outside of the hose must be prevented from coming in contact with the conveyed material, so that it is thereby possible to handle the filler hose and avoid pollution of the environment.
The object on which the invention is based is to provide a connecting system between a transportable vessel and a central filling station, having a flexible filler hose which can be matched vertically and horizontally to the position of the transportable vessel in relation to the discharge point of the supply container, but without the outside of the filler hose ever coming in contact with the filling material.
This object on which the invention is based is achieved by means of a flexible filler hose which is connected to clamping rings at both its ends and which is folded back on itself, a weighting ring being provided in the lower reversal region, thus always guaranteeing a correct downward-directed position of the filler hose, changes in height of the filler hose now being possible without the outside of the filler hose coming in contact with the free ambient air. Furthermore, the extent to which the filler hose penetrates into the transportable vessel is reduced by half, so that when equipment, such as paddles or the like, are arranged in the transportable vessel, the filler hose does not come in contact with these paddle devices.
At the same time, the filler hose can be transported together with the flexible vessel and, for example, its bottom end dips below the level of liquid in the transportable vessel, so that only the liquid located within the cross-section of the filler hose is in breathing contact with the atmosphere outside the vessel. Emissions of combustible liquids are greatly reduced as a result.
An exemplary embodiment of the invention is explained below with reference to the drawings. In the drawings:
FIG. 1 shows a part view of a transportable vessel with an attached filler hose and a cowl closing the latter, and
FIG. 1A shows a magnified cut-out view of FIG. 1 emphasizing holding lugs and corresponding recesses in the cowl, and
FIG. 2 shows the filler hose according to FIG. 1, in the extended state and connected to a discharge orifice for the flowable materials to be transported.
In the drawings, 1 denotes a transportable vessel which has a filler socket 2 on its topside. A first clamping ring 3 is connected to this filler socket 2 and fastened, for example, by means of appropriate hook fastenings 4. The first clamping ring 3 consists of an annular disk 5 with a central orifice, to which is adjacent a cylindrical connexion piece 6 directed upwards. Fastened to the outside of the cylindrical connexion piece, with a clip 7 interposed, is the bottom free end of a flexible filler hose 8 which, folded back on itself, is guided upwards so that it forms a reversal region 9 in the lower zone. Arranged in the annular space formed by this reversal region 9 is a weighting ring 10 which preferably consists of a round carrier unit, for example a wire or the like, on which spherical bodies 30 are arranged rotatably, so that, in the event of changes in length of the flexible filler hose 8, this weighting ring 10 can easily follow the movements of the hose
