Outlet nozzle for containers

The innovation concerns a conically tapering downwards Outlet nozzle at the base of a container for the transport of bulk goods, in which an air-permeable, but Aeration floor permeable to bulk material used with space in between is, and the one externally accessible compressed air connection opening into the space and one at the side has discharged extraction nozzle.

In the case of the previously known outlet nozzles of this type, the aeration base is attached to the upper and lower outlet nozzles On support rings, the fastening of the aeration base takes place releasably by means of screws or rivets. According to another known type, the ventilation base is attached to the upper support ring via a clamping ring and lies on the lower support ring only. For various bulk goods, loosening for emptying is not necessary, in some cases even a hindrance. For this reason, and for cleaning, it is necessary that the ventilation floor is arranged so that it can be easily replaced is. In the case of the above. Arrangement is a relatively large effort for the expansion, because the screws in the The load is lying and has therefore become difficult to move and the work has to be carried out in the dusty container.

The hiring has set the task of creating an outlet nozzle, with the ventilation floor through one only externally accessible screw is held.

According to the innovation, this object is achieved in that the Transition from the outlet nozzle to the outlet nozzle, basket-shaped and is designed to run out in the extraction nozzle, and which is designed accordingly in this area and in one Lying at a distance, an aeration base is detachably connected to the latter via a screw bolt arranged approximately centrally to the outlet connection.

In the drawing is an embodiment of the fire .in a vertical section through the outlet spout shyly shown.

At the base of the container, a recess is provided in a known manner, into which a cone-shaped downward tapered outlet nozzle 1 bit is welded to its flange 2, which receives a correspondingly designed ventilation base 3 at a distance. To get an even To obtain intermediate space 4- between the outlet nozzle 1 and the air-permeable, but bulk material-impermeable ventilation floor 3, circumferential sealing rings 5, advantageously Verichdichtuugen, are provided, which are arranged and are designed that they the gap ^ compared to the Cover the container and the removal spout 6 elastically when

However, discharged through the into the space 4 via the Do not deform incoming air using compressed air connection 7. To the releasable connection of the aeration base 3 with the outlet nozzle 1 is the transition from the outlet nozzle 1 to the extraction nozzle 6 designed in the shape of a basket arch in the lower area, c! m the formation of the ventilation floor 3 in this Area is adjusted. In this case, a vertically downwardly directed and centric to the outlet nozzle is on the ventilation base 3 1 lying threaded bolt 8 attached, which is guided through a hole in the outlet nozzle 1 and from the outside a nut 9 is held, the ventilation bed 3 being pulled against the seals 5 by tightening the nut.

To remove the ventilation base 3, only the approximately centrally located nut 9 needs to be loosened and the ventilation base and the seals 5 can be lifted up and removed via a boiler dome or manhole. The hole for receiving the threaded bolt 8 is closed by a blind plug and the container is ready for emptying without loosening.
