PULP HYDRAULIC TRANSPORT Russian patent published in 2020 - IPC E02F3/90 B65G51/01 

FIELD: mining.

SUBSTANCE: invention relates to the mining industry, in particular to the pulp lifting and transportation in the mineral deposits development, in which the desired product crushing is not desirable, for example, during the amber deposit development. Pulp hydraulic transport consists of pipeline, pulp separator with chamber separating pulp into transported and transporting flows. Conveying flow by means of the pressure pump is pumped under pressure to the pipeline, providing with energy the transported flow of pulp via the pipeline. At that, the pulp separator housing is communicated with the chamber with holes the size of which is determined by the size of the stored target product, and the chamber itself is communicated with the reservoir by means of accumulation and pressure pumps controlled by sensors of upper and lower levels of the reservoir and control valves of the pipeline.

EFFECT: technical result consists in improvement of extracted target product quality by preventing penetration of that part of target product into cavity of the blow pump, size of which is one of the main quality indicators of the extracted target product, higher efficiency of the installation, wider range of pulp hydraulic transport.
