Patent Searching and Data


Title:
ROTARY KILN
Document Type and Number:
Japanese Patent JPH10325683
Kind Code:
A
Abstract:

To supply sufficient air and facilitate the movement of waste by a method wherein air supplying holes are formed so as to be slanted from the inner peripheral surface of a kiln cylindrical body toward a direction opposite to the rotating direction of the kiln cylindrical body.

Air supplying holes 17 are formed so as to be slanted by an angle αfrom the inner peripheral surface of a kiln cylindrical body (cylindrical body) toward a direction opposed to the rotating direction of the cylindrical body and so as to be the same direction substantially as the tangential direction of the inner peripheral surface of the cylindrical body. Waste in the cylindrical body receives the effect of a centrifugal force, exerted from the rotating center of the cylindrical body toward the radial direction of the same, and the effect of an inertia force toward the rotating direction of the cylindrical body. Accordingly, the component force of centrifugal force and inertia force or a force from the inner peripheral surface of the cylindrical body toward a slanted direction in the rotating direction of the same is exerted on the waste near the inner peripheral surface of the cylindrical body. Further, air, supplied through the air supplying ports 17, flows along the inner peripheral surface of the circumferential wall 15 of the cylindrical body while being whirled. According to this method, the air is supplied smoothly and the waste, from fine granular waste to rough granular waste, can be treated efficiently.
