PULP HYDRAULIC TRANSPORTATION Russian patent published in 2020 - IPC E02F3/90 E02F7/00 

FIELD: mining.

SUBSTANCE: invention relates to the mining industry, in particular to the pulp lifting and transportation during development of mineral deposits, in which the desired product is not crushed, for example, in the development of an amber deposit and, respectively, in hydrotransportation of pulp containing amber. Pulp hydraulic transport consists of pipeline and pulp separator with chamber separating pulp into transported and transporting flows, transporting flow by means of pressure pump is pumped under pressure into pipeline, providing energy of pipeline transportation of transported pulp flow. Pulp separator housing is communicated with the chamber by holes, the value of which is determined by the size of the stored target product, and the chamber itself is communicated with a storage pump feeding the pulp into a reservoir with sensors of the upper and lower levels, which control operation of the accumulating and pressure pumps, and through them with the valves of the pipeline.

EFFECT: proposed hydrotransportation of pulp prevents destructive effect of booster pump on more valuable part of extracted target product and allows maintaining its quality.
