Study on improving performance of airlift device by self-excited oscillation pulsed jet used in mining under water

  • Published:
Journal of Coal Science and Engineering (China)

Abstract

The feasibility of the nozzle of self-excited oscillation pulsed jet (SEOPJ) as the breaker and loosing device for the air-lift pump was researched. The dynamic characteristics of the SEOPJ to crush the hard clay and loose the layer of ore deposit were explored experimentally under the submerged condition. The results show that the SEOPJ not only effectively breaks the hard clay or loose the particles of sand on the placer bed, but also produces fluctuating uplift force acting on particles of sand. The oscillating cross flow caused by the SEOPJ makes particles of sand move to the end of the suction pipe easily. Energy efficency of the airlift and concentration of the solids for the solid-liquid mixture sucked by the air-lift pump are increased obviously with the breaker of SEOPJ.
