Novel vertical shaft of flotation machine

Abstract

The utility model discloses a novel vertical shaft of a flotation machine, and belongs to the technical field of energy and metallurgical machinery. The device comprises a fixed seat, an upper shaft sleeve, a lower shaft sleeve, an upper main shaft, a lower main shaft, a water wheel cover plate and a water wheel rotor, the fixed seat covers a notch of a flotation machine tank body, the upper shaft sleeve penetrates through the fixed seat and is fixedly connected with the fixed seat, the bottom of the upper shaft sleeve is detachably connected with the lower shaft sleeve through a flange, and the bottom of the lower shaft sleeve is detachably connected with the water wheel cover plate. The upper main shaft is rotatably connected with the upper shaft sleeve through a bearing, one end of the upper main shaft penetrates out of the upper shaft sleeve and is connected with a driving mechanism, the other end of the upper main shaft is detachably connected with the lower main shaft, limiting pieces are installed in the upper shaft sleeve and the lower shaft sleeve, the other end of the lower main shaft penetrates through the limiting pieces and is detachably connected with the water wheel rotor, and the water wheel rotor is located outside the lower shaft sleeve. The main shaft is designed to be in two-section connection, so that the lower main shaft is convenient to disassemble, assemble and replace, and meanwhile, the use cost and the manufacturing cost of the main shaft are reduced.
