本発明は乾燥効率の悪い部分に流動層乾燥装置からなる
仕上乾燥部を有する蒸気管式回転乾燥機に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a steam tube type rotary dryer having a finish drying section consisting of a fluidized bed dryer in a portion with poor drying efficiency.
スチームチューブドライヤーとも称される従来の蒸気管
式回転乾燥機においては、回転するドラム内に導入した
被乾燥物を熱源である蒸気管からの伝熱により過熱して
水分を蒸発させ、その蒸発した水分をキャリヤーガスに
より糸外に排出乾燥させている。In a conventional steam tube rotary dryer, also known as a steam tube dryer, the material to be dried introduced into a rotating drum is superheated by heat transfer from the steam tube, which is the heat source, to evaporate moisture. Moisture is removed from the yarn using a carrier gas and dried.
しかしながら、この方式の蒸気管式回転乾燥機では、キ
ャリヤーガスと被乾燥物との接触が悪いため、製品乾燥
度が低水分上要求された場合、減率乾燥域効率が必ずし
も良いものとはならないという欠点があった。However, in this type of steam tube rotary dryer, the contact between the carrier gas and the material to be dried is poor, so when product dryness is required to be low in moisture, the lapse rate drying area efficiency is not necessarily good. There was a drawback.
そこで本発明は、前記従来の蒸気管式乾燥機の欠点を解
消し、蒸気管式回転乾燥機の特徴を最大限に生した恒率
乾燥域では従来通りの蒸気管式乾燥方式とし、効率の悪
い減率乾燥域では流動層乾燥方式をとり入れることによ
り、製品乾燥度が低水分上要求される場合にも充分対応
できる蒸気管式回転乾燥機を提供することを目的とした
ものである。Therefore, the present invention eliminates the drawbacks of the conventional steam tube dryer, and uses the conventional steam tube drying method in the constant rate drying region, which maximizes the characteristics of the steam tube rotary dryer, to improve efficiency. The purpose of this invention is to provide a steam tube type rotary dryer that can sufficiently handle cases where product dryness is required to be low in moisture by incorporating a fluidized bed drying system in the poor lapse rate drying region.

乾燥装置を設けることにより構成される。That is, the steam tube type rotary dryer having a finish drying section of the present invention is a steam tube type rotary dryer in which a steam tube is disposed in a rotating drum as a heat source, and a hood is provided around the outlet of the material to be dried in the drum. It is constructed by providing a fluidized bed drying device within the hood.

大の側断面図である。The present invention will be described in detail below with reference to the drawings. FIG. 1 is a side sectional view of a steam pipe rotary dryer according to an embodiment of the present invention, and FIG. 3 is a front sectional view, and FIG. 3 is an enlarged side sectional view of a main part showing the sealing portion between the drum and the hood portion of FIG. 1.
まず、この回転乾燥機は図示されていないモータ及びチ

。First, this rotary dryer consists of a drum 3 that rotates via tires 2 while being supported by a roller 1 driven by a motor and a chino (not shown). On the downstream side, there is a pressure rotary joint 4.
A steam pipe 5 connected to the drum 3 is provided, and steam S, which is a heat medium, introduced from the steam pipe 5 is circulated through a large number of steam pipes 6 provided to penetrate this drum 3 in the longitudinal direction, and is covered with steam. After the heat is transferred to the dried material M, it is discharged from the drain outlet lower part.
一方、この回転乾燥機により乾燥される被乾燥物Ｍは、
上流側に設けた被乾燥物人口９から導入され、キャリヤ

ガス出口１２から排出されるようになっている。On the other hand, the dried material M to be dried by this rotary dryer is
The carrier gas G introduced from the drying target 9 provided on the upstream side and the carrier gas G introduced from the carrier gas inlet 10 dries the drum 3 rotating in the direction of arrow R while moving it downstream. The carrier gas G that is taken out from the material outlet 11 and has reached the downstream side is discharged from the carrier gas outlet 12.
なお、被乾燥物Ｍによっては、キャリヤーガスＧの流れ
を上記実施例と逆方向に流すこともできる。Note that, depending on the material M to be dried, the flow of the carrier gas G can also be made to flow in the opposite direction to that in the above embodiment.
そこで本発明では、ドラム３の被乾燥物出口１１の周囲

At the bottom of the hood 13 is a fluidized bed 14 as shown in FIG.
A fluidized bed drying device is provided, which includes a hot air introduction hopper 15 at the bottom of the hot air introduction hopper 15, and hot air H from a blower and an air heater (not shown) is introduced from the bottom of the hot air introduction hopper 15 through the fluidized bed 14 to dry the dried material. The material M to be dried that has fallen into the hood 13 from the material outlet 11 is further dried, and the dried product is transferred to the Aero7 Cup 1.
It is designed to be taken out via 6.
以上のごとく、この回転乾燥機においては、第１図にて
Ｘで示す範囲が従来同様の蒸気管式乾燥部であり、Ｙで
示す範囲が仕上乾燥部になっている。As described above, in this rotary dryer, the area indicated by X in FIG. 1 is the steam pipe type drying section similar to the conventional one, and the area indicated by Y is the finishing drying section.
なお、このフード１３とドラム３との接合部は、第３図

A seal 20 pressed by a pressing spring 19 is in contact with the third side to maintain sealing performance.
従って、本発明の蒸気管式回転乾燥機は、従来の蒸気管

ことができ、乾燥工程の大幅省エネ化が可能である。Therefore, the steam tube type rotary dryer of the present invention takes full advantage of the features of the conventional steam tube type dryer while incorporating a fluidized bed drying method as a finishing drying section on the downstream side where drying efficiency is low. As the heat required for the finishing drying section, the sensible heat of the material to be dried heated in the steam tube rotary dryer can be utilized to the maximum extent, making it possible to significantly save energy in the drying process.
また、蒸気管式回転乾燥機と仕上乾燥部とが一体化され
ているので、乾燥機全体の長さを短かくできると共に、
仕上乾燥部での分級処理も可能になるという利点もある
。In addition, since the steam tube rotary dryer and the finish drying section are integrated, the length of the entire dryer can be shortened, and
Another advantage is that classification processing can also be performed in the finishing drying section.
