It has an inlet and two outlet ports arranged symmetrically at the bottom, and the inner cylinder has a diagonal outlet hole that allows communication between the inlet and one of the outlet ports, and the inner cylinder can be simply rotated. This makes it possible to switch the discharge path and stop discharge.
以下、この考案を図示する一実施例に基づいて
説明する。なお、従来と同一あるいは相当する部

図、第３図に示すように、この考案に係る排出切
換装置は、回転自在に支持されたドラム状の内筒
８と、この内筒を気密的に取囲む外筒９とからな
る。 This invention will be explained below based on an illustrated embodiment. Note that parts that are the same as or correspond to the conventional ones are given the same reference numerals and explanations are omitted. Second
As shown in FIGS. 3 and 3, the discharge switching device according to this invention consists of a rotatably supported drum-shaped inner cylinder 8 and an outer cylinder 9 that airtightly surrounds this inner cylinder.
外筒９の上部には、ホツパ２の下端部に気密的
に連通する導入口１０が形成され、外筒９の下部
には中央軸Ｃに対して線対称で位置する二つの排
出口１１，１２が形成されている。 The upper part of the outer cylinder 9 is formed with an inlet 10 that communicates with the lower end of the hopper 2 in an airtight manner, and the lower part of the outer cylinder 9 has two discharge ports 11 located symmetrically with respect to the central axis C. 12 are formed.
内筒８には、導入口１０と排出口の一方とを連
通し得る排出斜孔１３が形成され、この排出斜孔
１３には耐熱性の断熱材１４が内張され、通過す
る混合物Ｍの温度低下を防止する。 A diagonal discharge hole 13 is formed in the inner cylinder 8 and allows communication between the inlet 10 and one of the discharge ports.The diagonal discharge hole 13 is lined with a heat-resistant heat insulating material 14 to prevent the mixture M passing therethrough. Prevent temperature drop.
内筒８の両端部には、軸１５が突設され、この
軸１５が軸受１６により回転自在に支持され、図
示しない適宜の駆動源により回転するようにされ
ている。 A shaft 15 is provided protruding from both ends of the inner cylinder 8, rotatably supported by a bearing 16, and rotated by an appropriate drive source (not shown).
外筒９は、胴部９Ａとフランジ側板９Ｂとから
なり、この胴部９Ａと側板９Ｂとの間にパツキン
材１７が設けられ、これにより外気とのシールが
なされている。 The outer cylinder 9 consists of a body part 9A and a flange side plate 9B, and a packing material 17 is provided between the body part 9A and the side plate 9B, thereby creating a seal from the outside air.
また、装置の冷却のために内筒８の内部には、
軸１４の貫通孔１８を介して冷却水が循環するよ
うにされている。 In addition, inside the inner cylinder 8 for cooling the device,
Cooling water is circulated through the through hole 18 of the shaft 14.
このような構成において、第２図に示すように
混合物Ｍは、排出斜孔１３を通つて円滑に排出路
４へ排出され、図の位置から時計廻り方向へ内筒
８を回転させれば、排出が停止され、さらに回転
