Embodiment Construction
[0031] The high-pressure dilute-phase small-volume feeding device of the present invention includes a fluidization air pipe 1, a fluidization air control valve 2, an air supply pipe control valve 3, an air chamber 4, an air distribution plate 5, an air supply pipe 6, and a horn inlet. Material opening 7, porous ventilation plate 8, lifting section 9, conveying pipeline 11, discharge control valve 12, exhaust valve 13, bag dust collector 14, pressure air pipe 15, feeding port 16 and feeding tank. The top of the supplementary air pipe 6 is provided with a porous ventilation plate 8 and passes through the air distribution plate 5 to the bottom of the horn feed port 7 . The horn feed port 7 is arranged directly below the lifting section 9 , and the opening faces the fluidized air distribution plate 5 . The pipe diameter of the lifting section 9 is slightly smaller than the supplementary air pipe 6. Before starting work, add materials to the feeding tank through the feeding port 1...
