AI Technical Summary
【0008】 本開示のロータリーキルンの回転筒体によれば、ロータリーキルンで処理される被処理物の塊の粒径が、固定板の外縁部と回転筒体の内面との間に形成された隙間の幅よりも大きければ、回転筒体に被処理物が供給される一方の端部から回転筒体から処理された被処理物が排出される他方の端部に向かって被処理物の塊が回転筒体内を転がるのを止められるのに対し、塊となっていない被処理物は隙間を通過して他方の端部に向かって回転筒体内を移動できるので、比較的単純な構成で被処理物の塊のショートパスを抑制することができる。

Abstract
Claims
1. A cylindrical rotating body of a rotary kiln, The rotating cylinder is provided with at least one annular plate-shaped fixing plate, The at least one fixing plate is provided so as to face the axial direction of the rotating cylinder, A rotating cylinder in which a gap having a width in the radial direction of the rotating cylinder is formed between the outer edge of the fixed plate and the inner surface of the rotating cylinder.
2. A rotary kiln comprising the rotating cylinder described in claim 1.
3. The rotary kiln according to claim 2, wherein the rotating cylinder is provided such that one end is higher vertically than the other end.
4. The at least one fixing plate comprises a plurality of fixing plates provided at intervals in the axial direction of the rotating cylinder, The plurality of fixing plates include two fixing plates adjacent to each other in the axial direction, and the two fixing plates include a first fixing plate near one end of the rotating cylinder and a second fixing plate near the other end of the rotating cylinder. The rotary kiln according to claim 3, wherein the width of the gap formed between the outer edge of the second fixing plate and the inner surface is smaller than the width of the gap formed between the outer edge of the first fixing plate and the inner surface.
5. The rotary kiln according to claim 4, wherein at least one of the plurality of fixing plates is provided at a position closer to one end of the rotating cylinder than to the center of the rotating cylinder in the axial direction.
6. The aforementioned at least one fixing plate comprises only one fixing plate, The rotary kiln according to claim 3, wherein the one fixing plate is provided at a position closer to one end of the rotating cylinder than to the center of the rotating cylinder in the axial direction.
7. The rotary kiln according to any one of claims 2 to 6, wherein the inner surface is provided with at least one plate-shaped stirring blade that protrudes radially from the rotating cylinder and extends in the axial direction of the rotating cylinder.
8. Inside the rotating cylinder, at least one plate-shaped stirring blade is provided, which protrudes from the inner surface of the rotating cylinder in the radial direction and extends in the axial direction of the rotating cylinder. The rotary kiln according to claim 6, wherein the one fixing plate is located in the axial direction between the end of the stirring blade facing the one end and the one end.
9. Inside the rotating cylinder, at least one plate-shaped stirring blade is provided, which protrudes from the inner surface of the rotating cylinder in the radial direction and extends in the axial direction of the rotating cylinder. The rotary kiln according to claim 6, wherein the one fixing plate is located in the axial direction within the range where the at least one stirring blade is provided.
