(54) DEVICE FOR HYDRAULIC FEEDING OF BULK MATERIALS

(57) The invention relates to hydrotransport, namely to devices for the hydraulic supply of bulk materials. purpose

invention - enhanced operational capabilities. The device comprises a vertical chamber 1 with a bottom 2 and a perforated intake manifold 4 located along the axis of the chamber with an outlet nozzle 5 made expanding from the bottom and an end located above the bottom 2 with the ability to form a shutter of bulk material between the nozzle 5 and bottom 2. The pipe nozzle 3 is produced by supplying water radially to the axis of the chamber 1 through nozzles 6 of the discharge device located along the perimeter of the bottom 2. 3 sludge.

The invention relates to hydrotransport, and in particular to devices for the hydraulic supply of bulk materials.

The purpose of the invention is the expansion of operational capabilities.

Fig, 1 shows a diagram of the device section; in FIG. 2, a bottom section with nozzles; fig.Z - the same, with the shutter open.

The device contains a vertical chamber 1 with a horizontal bottom 2, a receiving pipe 3 of the pipeline, a perforated water intake manifold 4 with an outlet 5, a discharge device with nozzles 6. The device operates as follows.

Bulk material enters chamber 1 and is deposited on bottom 2. At the same time, bulk material flows through the gap between bottom 2 and branch pipe 5 of the intake manifold and settles on the bottom with the formation of natural slope 7 (Fig. 2) that does not extend beyond horizontal bottom 2. Thus, between the nozzle 5 and the bottom 2, a bulk material shutter is formed, preventing material from entering chamber 1 into the receiver nozzle 3 of the pipeline. Liquid from the upper part of chamber 1 flows through the perforated intake manifold 4 into the receptacles Nozzle 3 Unloading bulk material is carried out by supplying water in the zone of repose 7 (Fig. 3)

Water is fed around the perimeter of the bottom radially to the axis of the chamber 2 through the nozzles 6 of the discharge device. Water can be supplied, for example, through the annular

pipeline through slots in it.

The ratio of water to solid at the inlet of the hydrotransport unit 8 is controlled by changing the flow rate and pressure of water supplied through the nozzles 6.
