Description

one

Devices for eliminating hang-up of difficult-flowing materials in a hopper are known, which contain a flexible hose introduced into the hopper's opening, the upper end of which is fixed to a trolley that is movable along the hopper opening and is connected to a source of compressed air, and the lower one is equipped with nozzles. However, in the known devices, the elimination of material hang-up is performed only at the same level along the height of the bunker.

In order to eliminate material hanging at any level along the height of the hopper in the proposed device, a winch is mounted on the trolley, the upper end of the sleeve is wound on the winch drum, another flexible sleeve is placed inside the upper sleeve, the upper end of which is also connected to a source of compressed air, and mounted on the lower one pneumopunch. Nozzles sleeves in such a device can be equipped with check valves.

FIG. 1 schematically shows the described device; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a section along BB in FIG. 2

The device comprises a flexible sleeve 1, the upper end of which is wound on a winch drum 2 (not shown) mounted on a trolley 4 movable along the discharge opening of the hopper 3 and connected to a source of compressed air by means of a hose 5 and

the distributor 6. The lower end of the sleeve 1 is equipped with nozzles 7 with check valves 8 in the form of, for example, elastic plates attached bottom to the nozzles. Inside the sleeve 1 is placed another flexible sleeve 9, the upper end of which is also connected to the source of compressed air through the distributor 6, and the pneumatic punch 10 is mounted on the lower end.

The carriage 4 is installed in the place where the material hangs in the hopper 3. Then the drum 2 rotates toward the unwinding side of the sleeve 1. At the same time, compressed air is supplied to the sleeve 9, as a result of which the pneumatic punch 10

breaks through the material well into which the sleeve 1 is inserted. When the lower end of the sleeve 1 reaches the level of material sticking, compressed air is fed into it, which, coming out of the nozzles 7, destroys the formed material arch and eliminates the hang. By raising or lowering the lower end of the sleeve 1, it is possible to eliminate material sticking at any level along the height of the hopper 3.

Claims (2)

1. Device for de-hovering difficult loose materials in the bunker, containing a flexible hose inserted into the loading opening of the bunker, the upper end of which is behind. mounted on a trolley that is movable along the opening of the bunker and connected to a source of compressed air, and the lower one is equipped with nozzles. 1 9 that, in order to eliminate material sticking at any level along the height of the bunker, a winch is mounted on the cart, the upper end of the sleeve is wound on the drum The winch has another flexible hose inside the upper sleeve, the upper end of which is also connected to the compressed air source, and the pneumatic punch is mounted on the lower one. 2. A device according to claim 1, characterized in that the nozzles are provided with check valves. 6 Fvg .2 5-5 5
