【考案の詳細な説明】
本考案は、サイクロン分離器における粉体排出装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powder discharge device in a cyclone separator.
搬送空気と粉体との分離にはサイクロン分離器が一般に
用いられているが、この種の分離器の内部気流は半自由
渦を形式しているので、負圧作動のときはもち輪、正圧
作動のばあいにも、中心部が大気圧以下になる。A cyclone separator is generally used to separate conveying air from powder, but the internal airflow of this type of separator is in the form of a semi-free vortex, so when operating under negative pressure, Even in the case of pressure operation, the pressure in the center is below atmospheric pressure.
そのようなサイクロン分離器から分離された粉体を搬出
搬送するために、一般には、その下端の粉体取出口にロ

できず、特に吸引形式のサイクロンにおいては、空気の
漏れのために、サイクロン下部の反転気流により粉体の
巻上げ散逸即ち吹き返しが増大し、集塵効率が著しく低
下する欠点があった。In order to transport the separated powder from such a cyclone separator, a rotary valve or butterfly valve is generally installed at the powder outlet at the lower end of the cyclone separator, but both of these have a complete sealing function. In particular, suction-type cyclones have the drawback that, due to air leakage, the reversing airflow at the bottom of the cyclone increases the amount of powder being thrown up and dissipated, that is, blowing back, resulting in a significant drop in dust collection efficiency. .
さらに、バルブ部分には、粉の噛込みや付着などが生じ
、排出作用が円滑に行なわれなくなる。Furthermore, powder gets caught or adheres to the valve part, making it difficult to discharge the valve smoothly.
本考案は、従来の構造のこのような欠点を解消して、集
塵効率を低下させることなく、分離された粉体の搬出を
円滑に行なわれるようにせんとするものであって、サイ
クロン下部に細長いノズルを設け、このノズルを吸引搬
送管に臨ませたことを特徴とする。The present invention aims to eliminate these drawbacks of the conventional structure and allow the separated powder to be carried out smoothly without reducing the dust collection efficiency. It is characterized by having an elongated nozzle facing the suction conveyance pipe.
すなわち、吸引搬送管の負圧はサイクロン下部の負圧よ
り真空度が高く、粉体はサイクロンから連続的に排出さ
れるようになる。That is, the negative pressure in the suction conveyance pipe has a higher degree of vacuum than the negative pressure in the lower part of the cyclone, and the powder is continuously discharged from the cyclone.
以下、本考案の実施例を図について説明する。Hereinafter, embodiments of the present invention will be described with reference to the drawings.
１はサイクロン分離器で、下部には粉体取出口２が設け
られている。1 is a cyclone separator, and a powder outlet 2 is provided at the bottom.
各サイクロン１の粉体取出口には、細長いノズル３が形
式され、このノズル３は、吸引搬送管４に対し横向きに
位置しそして吸引搬送管４内の搬送流に沿って下流方向
に向いて吸引搬送管４内に突き出して配置されている。An elongated nozzle 3 is formed at the powder outlet of each cyclone 1, and this nozzle 3 is located laterally to the suction conveyance pipe 4 and is oriented downstream along the conveyance flow in the suction conveyance pipe 4. It is arranged to protrude into the suction conveyance pipe 4.
吸引搬送管４は空気取入口５およびダンパ６を有し、下
流部分に設けられた吸引ファン（図示せず）により吸引
が行なわれる。The suction conveyance pipe 4 has an air intake port 5 and a damper 6, and suction is performed by a suction fan (not shown) provided at the downstream portion.
したがって、吸引搬送管４中のノズル３からの排出部に
おける負圧は、サイクロン１内のそれより真空度が高く
、サイクロン１の底部にたまった粉体は連続的に吸出さ
れる。Therefore, the negative pressure at the discharge section from the nozzle 3 in the suction conveyance pipe 4 has a higher degree of vacuum than that in the cyclone 1, and the powder accumulated at the bottom of the cyclone 1 is continuously sucked out.
ノズル３は、固定板７および可動板８により調節可能に
構成することが好ましい。Preferably, the nozzle 3 is configured to be adjustable by a fixed plate 7 and a movable plate 8.

く、従来経験されたようた粉体の吹き返しを完全に防止
できる。As explained above, in the present invention, an elongated nozzle is formed at the powder outlet of the cyclone separator, and this nozzle faces the suction conveyance pipe, so that the pressure inside the cyclone is transferred to the nozzle discharge part in the conveyance pipe. The pressure does not drop below that level, and the blowback of powder that has conventionally been experienced can be completely prevented.
