In the dust collector for a cutting facility having the third configuration, the periphery is partitioned by the bottom, side walls, and ceiling, so that the dust simply floats in the dust storage means on an upward air current. This floating dust is easily collected by dust collection means. Therefore, the dust does not jump up, and is collected by the dust collection means while it is floating, and is prevented from floating further upward by the ceiling of the dust storage means, so that it does not blow up onto the cutting table. do not have.
なお、各構成において、集塵口を底部から所定′距離上
方に開口させているから、ここから切断滓を吸い込むこ
とがなく、円滑な集塵作業を実行することができる。In each configuration, since the dust collection port is opened a predetermined distance above from the bottom, the cutting slag is not sucked in from there, and the dust collection operation can be performed smoothly.

のは、切断作業を行なう位置をあまり高くしないためで
ある。This amount of digging was determined from the bottom 30, because it was experimentally confirmed that when high-pressure gas with a pressure of 5 kg/an2 is ejected from the cutting machine 7, the momentum of the high-pressure gas is lost at a position approximately 1600 mm away. This 16 height up to 3,4
This is determined based on the condition that the interval is such that 00rryn can be secured. Note that the reason why the bottom 30 is dug down is to prevent the cutting work from being performed at a very high position.

と同様のものである。As shown in Fig. 2, the conventional device was configured so that dust was only discharged from the rear wall 0 section under the cutting table C to the outside through the chimney H.The dust situation in this conventional device was as follows. If the amount generated was 100%, 50% was emitted from the chimney and the remaining 50% spewed out from the bill cutting table. At this time, the capacity of the blower that sucks the dust into the chimney is the same as in the embodiment.

のは発生量の３０％に過ぎず、かえって切断台Ｃからは
７０％もの粉塵が噴き上がるという結果であった。The first improved device was designed to collect dust by installing a dust collector K here instead of discharging it from the chimney H.In addition, in order to form a dust collection position, an example was installed at a predetermined position in the vertical direction. With this device, the amount of dust emitted from the upper chimney H to the outside was rQJ, but the amount of dust that could be collected by the dust collector was only a fraction of the amount generated. The result was that 70% of the dust was blown up from the cutting table C.
そこで、第２の改良装置として、前面にも壁を配置した
今度は、切断台Ｃからの噴き上がりは若干減少し、６５
