UNIT FOR BULK MATERIAL HYDROTRANSPORTATION Russian patent published in 2017 - IPC F04D13/12 F04F5/54 F04D29/70 

FIELD: engines and pumps.

SUBSTANCE: unit contains devices (1 and 2) of charge and discharge, separator (3), pipe connections (9) and a centrifugal pump (5), linked to a mixing chamber (6). The separator (3) represents a bent branch pipe which can change its bend and is connected to a splitter (4). A receiving device (8) is installed in the inclined branch pipe of the splitter (4) and can change the depth of penetration into its inner cavity, coupled with the pump (5) via the pipe connection (9). The pump (5) is connected to the mixing chamber (6) in its lower part through an outlet pipeline (11).

EFFECT: simplified unit design due to removing the separator drive, possibility of separation degree control, reduction of pump wear intensity and increase in its lifetime due to protection of the pump from solid particles.
