SLURRY CASCADE HYDRAULIC TRANSPORT Russian patent published in 2022 - IPC E02F3/88 E02F7/10 E21C50/00 

FIELD: mining industry.

SUBSTANCE: invention relates to the mining industry for lifting and transporting slurry during the development of mineral deposits. Cascade hydraulic slurry transport contains a slurry lifting stage in the form of a conveying pipeline, a slurry splitter separating the slurry into transported and transporting flows through holes, the size of which is determined by the size of the stored target product. The conveying pipeline is connected to the tank by a supply pipeline with a suction pump and a discharge pipeline with a discharge pump and an upper-level sensor controlling the process of filling and emptying the tank. The cascade hydraulic pulp transport additionally contains at least one slurry lifting stage installed in series, containing a conveying pipeline, a slurry splitter separating the slurry into transported and transporting flows through holes, a tank with an upper-level sensor connected to the conveying pipeline by a supply pipeline with an electric valve and a discharge pipeline with a discharge pump. An electric valve is installed in the upper head of the conveying pipeline of each lifting stage.

EFFECT: transportation of pulp to the required distance and height without impact on the target product and maintaining the quality of the extracted target product.
