The invention relates to a gas-
solid separating
garbage disposal machine provided with sliding guiding rings. According to the
machine, a feed inlet is formed in the upper end of an ejection steel cage, the lower end of the ejection steel cage and a
piston rod of an ejection triggering cylinder are fixed together, a feeding
screw cap is installed on the feed inlet of the ejection steel cage, a gas-
solid separator is connected to the lower end of a
steam pressure maintaining
steel cylinder through a discharging guiding cylinder, a steam inlet is formed in the
steam pressure maintaining
steel cylinder, supporting pillars are evenly and fixedly installed between an upper sliding disc and a lower sliding disc around the feed inlet, the bottom of the lower sliding disc and the
piston rod of the ejection triggering cylinder are fixed together, the sliding guiding rings are arranged on the middle portions of the supporting pillars, an upper sealing
rubber ring is fixedly installed on the outer wall of the upper sliding disc, and a lower sealing
rubber ring is fixedly installed on the outer wall of the lower sliding disc. The
machine is simple in structure, adaptable to instant ejection, resistant to
high pressure and high in strength, feeding is convenient, discharging is even and orderly during steam ejection, steam and
slurry can be effectively separated, and ejection sliding is more stable.
