摘要
Disclosed is a vertical pulping machine for mine fire preventing and fighting, comprising a hopper (1), an inner barrel (6), and an outer barrel (5), a spiral conveyor (11) and a stirring device. A clearance is kept between bottoms of the inner barrel (6) and the outer barrel (5), and between an outer wall of the inner barrel (6) and an inner wall of the outer barrel (5) such that the inner barrel (6) is able to rotate relative to the outer barrel (5). The outer barrel (5) has a concave bottom, and is fit with an impeller (8) in the clearance. The outer barrel (5) has a pulp outlet (4) provided on a side wall, and a dreg discharging port (10) provided on a lower part. One side of the outer barrel (5) is provided with the spiral conveyor (11), and one end of the spiral conveyor is connected to the dreg discharging port (10) via a pipeline. A dreg scraping plate (7) is provided on a lower part of the inner wall of the inner barrel (6), and a dreg discharging hole (16) is provided on a front side in a rotating direction of the dreg scraping plate (7). The pulping machine is able to filter impurities without a filter screen, can produce an even pulp, has a low energy consumption, and a good dreg discharging effect.
