摘要： PROBLEM TO BE SOLVED: To minimize heat dissipation loss at the terminal part of a tube by a method wherein a driving plate is attached to a graphite pipe indirectly while a flexible atmosphere seal assembly, a heating chamber and a heating body are provided on the periphery and the inside of the graphite tube. SOLUTION: In order to transfer a rotating torque from a motor power source to a graphite tube 2 through a driving plate 14 while allowing the difference of thermal expansion, the driving plate 14 is attached to the graphite tube 2 indirectly through a key, a spline or a similar interlocking unit 15. In this case, one set or more of flexible bellows 19 or another load spring type seal assembly, a heat insulating heating chamber 11 surrounding a heating area 4, an electric heating body in the heating chamber for sealing a selected atmosphere around and inside of the graphite tube 2 during rotating are equipped. According to this method, heat dissipation loss at the terminal part of the tube can be minimized.

摘要： PROBLEM TO BE SOLVED: To enable a staying time of ignited substances within a rotary incinerator to be adapted for the most suitable incineration time for the ignited substances. SOLUTION: A lateral rotary type incinerator 12 is provided with a cylindrical rotary furnace 4 arranged in a lateral orientation so as to ignite waste material within it. A supplied end section 4a is ascended or descended by an inclination angle adjustment means 15 around an inclination central point of a discharging end 4b of the rotary incinerator 4, thereby changing an inclination angle of the rotary incinerator 4, a staying time of the ignited substances within the rotary incinerator is adjusted so as to be adapted for the most suitable incineration time of the ignited substances.

摘要： PROBLEM TO BE SOLVED: To prevent the penetration of outside air by providing a discharge chamber with an auxiliary burner which jets out combustion flame for interrupting the outside air penetrating from the space between a retort and the discharge chamber. SOLUTION: The matter to be calcined sent in by a belt conveyor 4 is combusted by the flame jetting out from a main burner 7 mounted on a discharge cylinder 6 constituting a discharge chamber 5 provided at the left end while being carried left accompanying the rotation of a retort 1, and then, it is let fall into the discharge chamber 5, and the combustion gas produced in the retort 1 is discharged from the exhaust cylinder 9 constituting the exhaust chamber 8 provided at the right end, thus narrow space a is provided between the discharge cylinder 6 and the retort 1. An auxiliary burner 10 for jetting out the combustion flame for interrupting outside air penetrating from the space a is mounted on the top end of the discharge chamber 5 within the discharge cylinder 6. As a result, the penetration of outside air can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent the run of material over a dam, seal a space between a material charging device and a vessel easily and permit operation with a large space factor, which was not available by a conventional device, by a method wherein a space factor in the upstream side of the dropping point of charging material is made smaller than that in the downstream side of the same. SOLUTION: A material inlet port 11a in a cylindrical vessel 11 is structured so that material is discharged continuously out of a material outlet port while charging the material 2 into the vessel through the material inlet port 11a under a condition that the vessel is rotated about the axial center of the same. The upper surface is a plane parallel to the stationary accumulating slope of the material 2 charged through the central point of the vessel 11 during rotating while a downstream side side surface 12c is arranged so as to insert a lifter plate 12, formed spirally in the advancing direction of rotation of the vessel 11, into a material inlet port 11a in the vessel 11 from the outside of the vessel 11 through a stand 13 so that the upstream side side surface 12a becomes orthogonal to the central axis of the vessel 11.
