ａ 産業上の利用分野
本考案は、サイクロン集塵機に関し、とくに、
集塵操作が必要でかつ操作上の負荷変動が大きい
工程に適するサイクロン集塵機に関する。[Detailed description of the invention] a. Industrial application field The present invention relates to a cyclone dust collector, in particular,
This invention relates to a cyclone dust collector suitable for processes that require dust collection operations and have large operational load fluctuations.
ｂ 従来の技術
従来、サイクロン集塵機は、集塵の必要な流体
のライン内に設置され、用いられていた。b. Prior Art Conventionally, a cyclone dust collector has been installed and used in a fluid line that requires dust collection.
ｃ 考案が解決しようとする課題
例えば、セメント製造ラインに設けられたサイ
クロン集塵機（以下サイクロンという）は、ミル
が停止している乾燥工程においても、ラインを流
れる熱ガスは通さなければならない。c. Problems that the invention aims to solve For example, a cyclone dust collector (hereinafter referred to as a cyclone) installed in a cement manufacturing line must allow hot gas flowing through the line to pass through even during the drying process when the mill is stopped.
従来のサイクロンでは集塵の必要のない（或い
は後段の集塵機のみで十分な）場合においても、
サイクロンの圧力損失は負荷時と同じかあるいは
やや高い。これは、従来のサイクロンの構造が固
定的で負荷変動に対処できないためである。 Even in cases where there is no need for dust collection with a conventional cyclone (or only a downstream dust collector is sufficient),
The pressure loss of the cyclone is the same or slightly higher than under load. This is because the structure of conventional cyclones is fixed and cannot cope with load fluctuations.
ｄ 課題を解決するための手段
第６図はセメント焼成炉ａから乾燥機ｂを経て
煙突ｃに至るまでのフローを示す。ｄはサイクロ
ン、ｃは風車、ｆは電気集塵機である。d Means for Solving the Problems Figure 6 shows the flow from the cement kiln a to the chimney c via the dryer b. d is a cyclone, c is a windmill, and f is an electrostatic precipitator.
このような工程の場合、集塵用サイクロンは、
無負荷（乾燥機に原料が入つておらず、ダクトの
発生が無い）のときでも、ガスの経路として高圧
損のまま使用しなくてはならず、風車動力の無駄
がある。乾燥機が無負荷のときには、サイクロン
を何らかの形で低圧損化すれば、後段の風車動力
を低減できる。 For such processes, the dust collection cyclone is
Even when there is no load (there is no raw material in the dryer and no ducts are generated), it must be used as a gas route with high pressure loss, resulting in wasted wind turbine power. When the dryer is under no load, if the pressure loss of the cyclone is reduced in some way, the power of the wind turbine in the latter stage can be reduced.
サイクロンの圧力損失は、主に、流体の旋回動
力である（この旋回の力によつて、粒子を流体か
ら分離させる）から、集塵操作を必要としないよ
うな場合には、むしろサイクロン内における流体
の旋回を阻止すれば、圧力損失は低減させること
ができる。 The pressure loss of a cyclone is mainly due to the swirling power of the fluid (this swirling force separates particles from the fluid), so in cases where dust collection is not required, the pressure loss in the cyclone is rather Pressure loss can be reduced by preventing fluid swirl.
本考案は、この点に着目してなされたもので、
その要旨は、内筒の一部に入口ダクトに向けて開
閉自在な開閉部を設け、該開閉部を開いたときに

状態を示し、仮想線は開いている状態を示す。 By rotating the motor 8 in forward and reverse directions, the support shaft 6 is rotated via the transmission element 7, and the opening/closing section 5 is opened and closed. In FIG. 5, solid lines indicate a state in which the opening/closing portion 5 is closed, and imaginary lines indicate a state in which it is open.

定める。 The opening/closing part 5 is connected to the inlet duct 3 as shown in FIG.
The range of angle α, for example, 120° to imaginary line L that is parallel to the mounting direction and passes through the center of the inner cylinder 4.
It is preferable that the front edge of the opening/closing part 5 is provided in a range of 150° and that when opened, the front edge of the opening/closing part 5 comes into contact with the outer cylinder 1 and closes the passage between the inner cylinder and the outer cylinder. Also, its height

When the cyclone of the present invention is used and the opening/closing part 5 is opened, the airflow is guided by the opening/closing part 5 as shown in FIG. 4, immediately enters the inner cylinder 4, and flows out.
一般にサイクロンの圧力損失は、その大部分が
気流の旋回エネルギーによつて生じるから、上記
