摘要： PROBLEM TO BE SOLVED: To provide a screw conveyor having excellent sealing property and hardly generating turn of an object to be handled together with a screw blade when conveying the object to be handled into a depressurized region.
SOLUTION: In this screw conveyor constituted in such a way that a screw 15 in which screw blades 17 are integrally connected with a cantilever rotary shaft 16 supported by only a bearing 18 arranged on a supply side of the object to be handled in a horizontal or substantially horizontal cylindrical casing 11 in which a supply port 12 and a discharge port 13 for the object to be handled are provided in end parts apart from each other is inserted into the casing 11, a screw blade missing section X in which only the screw blade 17 is missing while the rotary shaft 16 is left as it is is formed in the axial direction of at least one screw 15 between the supply port 12 and the discharge port 13 when conveying the object to be handled into the pressure reducing region, and screw blade providing sections W, W separated on both sides in the direction of screw shaft 16 in the screw blade missing section X are formed.

摘要： PROBLEM TO BE SOLVED: To provide a screw conveyor capable of preventing biting accident when conveying an object to be handled having large size and a complicated shape hardly allowing easy swallow into a casing on, in particular, a supply port side.
SOLUTION: This screw conveyor is constituted in such a way that a screw 15 in which a screw blade 17 is integrally connected with a cantilever rotary shaft 16 supported by only a bearing 18 arranged on a supply side for the object to be handled in a horizontal or substantially horizontal cylindrical casing 11 in which a supply port 12 and a discharge port 13 for the object to be handled are provided in end parts separated from each other, respectively, is inserted into the casing 11. The inner diameter of the casing 11 is formed to be larger than that of the screw blade 17 markedly so that a clearance C between an inner face of the casing 11 and it at an upper end of the screw blade 17 is larger than that at a lower end of the screw blade 17 markedly. An axis AC of a rotary shaft 16 is eccentric downward relative to the center CC of cross section of the casing 11.

摘要： PROBLEM TO BE SOLVED: To provide a gas seal device for a rotary drum whose sealing performance can be held good even in the case where a gap of a certain minor dimension exists between the sealing surfaces of a rotation side sealing member and a stationary side sealing member.
SOLUTION: While the rotary drum 11 is in rotation, a gap of a certain minor dimension may be generated between the sealing surface of the stationary side sealing member 21 and the sealing surface of the rotation side sealing member 22. From a gas container B, an inert gas with a higher pressure than the inner gas in the rotary drum 11 is supplied to between the two sealing surfaces. Even if any gap is formed between them, the inert gas seals inside the rotary drum 11 from the outside. Thereby the sealing performance of the rotary drum 11 can be held. As a result, the drum 11 can be operated stably.
