INSTALLATION FOR HYDROTRANSPORTATION OF LOOSE MATERIALS Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: selective tee-joint positioned at output of ejector mixing chamber is provided with self-cleaning filter. Removing cavity of tee-joint is coupled to suction section of pump, and delivery cavity of pump is coupled to active nozzle of ejector so that they constitute closed circuit "pump - ejector - selective tee-joint - pump" for circulation of auxiliary liquid through which additional power is transmitted to hydraulic mixture. Optimal zone of installation operating characteristics is determined by relation of expendable parameters of charging device and pump within range of 0.6-1.2. Empirical formula is proposed for determination of pumping installation efficiency. Proposed invention enables reduction of power consumption required for loose material hydrotransportation with preservation of granulometric composition of materials. EFFECT: improved design. 2 cl, 2 dwg
