Conventional upright cyclone dust collectors have an inverted conical lower part of the outer cylinder with an air inlet to increase efficiency. In addition, in a so-called cylindrical cyclone that does not have a conical portion, the length of the outer cylinder is set to be sufficiently larger than the length of the air outlet inner cylinder. The reason is that when the outer cylinder is short, the volume of the swirling flow of suction air at the upper part does not decrease even at the lower part, so the force of the swirling flow at the lower end does not decrease. Therefore, as shown in FIG. 5, when the powerful swirling flow of the actual battle arrow reverses and rises as indicated by the dotted line arrow on the upper surface of the dust box 12. The dust 16 inside the dust box is
It is rolled up, placed on an upward flow, and discharged into the atmosphere through a pipe. This greatly reduces dust collection efficiency. As a countermeasure for this, if the outer cylinder is made sufficiently high, while the swirling airflow moves from the upper end of the outer cylinder to the downstream part, the inner cylinder will act to suck the swirling airflow, and the volume of the swirling airflow at the lower end will be significantly reduced. As the air volume decreases, the force of the winding becomes weaker, and the winding up of dust is suppressed.
従来のサイクロン集塵機は上述の構造によつて
形状寸法と重量が大となる。
The conventional cyclone dust collector has a large size and weight due to the above-described structure.
しかし、粉塵が発生する場所が、作業位置の移
動に伴つて変る作業現場では、作業環境を良好に
保持するために、集塵機設置場所の移動が容易で
あることが必要である。従つて、大形で重量の大
なる集塵機はこれに適していない。 However, in a work site where the location where dust is generated changes as the work location moves, it is necessary to easily move the dust collector installation location in order to maintain a good working environment. Therefore, large and heavy dust collectors are not suitable for this purpose.
この発明の目的は、円筒形サイクロンの外筒が
短く、しかも、集塵効率が良好で、構造簡単、形
小、軽量で、作業場での移動が容易な吸引式集塵
機を提供することである。
An object of the present invention is to provide a suction type dust collector that has a short outer cylinder of a cylindrical cyclone, has good dust collection efficiency, is simple in structure, small in size, lightweight, and easy to move in a workplace.

The operation of the present invention will be explained using FIGS. 3 and 6.

よつては浮き上らない。一方、円筒１４によつて
上行した旋回気流の勢力は大であるが、円筒１４
の内部にはダストが存在しないから、戻り気流に
よるダストの再飛散は発生しない。 As shown in FIG. 6, the force of the airflow that descends while swirling inside the outer cylinder does not weaken even on the upper surface of the dust box 12. Therefore, by contacting the upper surface of the dust 16 accumulated on the outside of the cylinder 14, the dust on the upper surface is caused to pivot horizontally toward the center of the box. However, the moved dust loses kinetic energy due to friction while rotating while contacting the outer surface of the cylinder 14, so it may collide with the cylinder 14 and float up due to the upward airflow. No. On the other hand, although the force of the swirling air flow ascending through the cylinder 14 is large, the cylinder 14
Since there is no dust inside, there is no re-scattering of dust due to return airflow.
このようにして、ダストボツクス１２内にダス
トが充満するまでの間は、円筒１４がダストの再
飛散に防止する。 In this way, the cylinder 14 prevents the dust from scattering again until the dust box 12 is filled with dust.
円筒１４の設置によつて、外筒の高さを通常の
サイクロンの1/2にすることができる。 By installing the cylinder 14, the height of the outer cylinder can be reduced to 1/2 that of a normal cyclone.
