Conventionally, for example, Japanese Patent Publication No. 52-52545, Utility Model Publication No. 51-
As shown in Publication No. 42841, the amputated leg IIt is divided into small rooms by a large number of partition plates, and a main duct is connected to each small room via a damper that can be opened and closed respectively, and the damper near the cutting torch is connected as appropriate. A method has been developed to exhaust smoke locally, but this type of method requires a long make duct that spans the entire area of the cutting surface, a damper that connects the main duct and a small chamber, and a mechanism to control its opening and closing. There were drawbacks such as a large number of required equipment, an enormous cost for incidental equipment, and difficulty in putting it into practical use.

Furthermore, as shown in FIG. 3, the lower part of the surface plate 7 is housed in a water tank 13, and the lower part of the partition plate 9 and the hood 12 are installed so as to be immersed in the water of this water tank 13. It is also possible to reduce the area of the lower space and improve the sealing performance of the smoke exhaust, thereby reducing the size of the smoke exhaust device. In addition, when 13 water tanks are used as described above, the dust generated during plasma cutting is submerged in water tank 13 to remove large particles from the smoke and thereby prevent an increase in the atmospheric temperature in the 7-door. This makes it possible to reduce the amount of smoke emitted by dust and improve the smoke exhaust effect.

As described above, the method according to the present invention includes mounting a dust collector for exhaust gas treatment on the main body of the cutting machine or installing it separately, and dividing the lower part of the surface plate into several blocks with a partition plate to create a partitioned space. Further, a retractable hood is slidably provided on the side of the partitioned space, and is connected to the suction dust collector, and is moved as the main body moves to suck out smoke from each partitioned space. [
Since it is configured to process the water, it eliminates the need for a long main duct that spans the entire range of the surface plate, a damper that connects each small chamber, and its opening/closing control mechanism, etc., which is required in the past, and the need for incidental equipment is significantly reduced. It has the characteristic that the equipment can be made compact.
