DEVICE FOR HYDRAULIC TRANSPORT OF LOOSE MATERIALS Russian patent published in 2016 - IPC F04D7/04 F04D29/70 B04B3/00 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic transport of loose materials, sludge, particularly for pumping of liquids with considerable content of suspension, having abrasive capacity. Device for hydraulic transport of loose materials comprises loading device (1) and unloading, housing (3), inside which there is vertical drive shaft (4) with cone nozzle (5), nozzle (6) output of cleaned phase and branch pipe (8) for outlet of condensed phases. Branch pipe (6) is connected with rotary pump (7), and branch pipe (8) is connected with mixing chamber ((9). On surface of nozzle (5) there are holes (10) arranged in circular rows. Size of holes (10) decreases from lower row to upper row. Mixing chamber (9) is made in form of hollow toroid in upper part of which there is a window (11). Unloading device represents a branch pipe arranged at an acute angle to plane of mixing chamber (10).

EFFECT: invention is aimed at creation of simple and reliable device for hydraulic transportation, which provides low wear of working elements in operation.
