SKIP HOISTING SYSTEM Russian patent published in 2018 - IPC B66B9/04 B66B17/08 

FIELD: transportation.

SUBSTANCE: invention relates to lifting devices, namely to the equipment of the lift section of the barrel by mining skip hoists. In the skip hoisting system, the lower part of the discharge line is connected by an air duct to the blower inlet, and guiding-sealing devices are placed on the cylindrical part of skips. Internal diameter of the pipelines is calculated depending on the specific values of the skip mass, the mass of the transported material, the air density at the inlet and outlet of the blower at atmospheric pressure.

EFFECT: connection of the drain pipe to the blower inlet, reduction of the number of guiding and sealing devices and their installation on the skip will reduce the energy costs of the skip pneumo-lifting plant by reducing the aerodynamic resistance of the route and eliminating the irrecoverable energy costs to raise its own weight of the skip.
