Further, FIG. 3 is a transverse sectional view of the separation tank shown in FIG. 2, and FIG. 4 is a partially cutaway plan view showing a chain-rod connecting portion arranged in the separation tank.

In the figure, reference numeral 1 is a separation tank having a predetermined length and width, the upper end of which is open, and a duct 3 for supplying drainage 2 containing powder particles discharged from a machine tool or the like is provided above the central portion of the separation tank. . 4 is a float switch, which turns on when the water level of the drainage 2 in the separation tank 1 rises, closing the electric circuit,
The motor 8 is started and the paper filter 13 is sent. Reference numeral 5 is a sprocket arranged at the front end and the rear end of the separation tank 1, and its rotating shaft 6 is supported by a bearing 7. 8 is a motor with a reduction gear, which is attached to the outer surface of the tip of the separation tank 1 via a flange,
When the motor 8 is driven, the rotational force of the motor 8 is transmitted via the chain 9 to the rotation shaft 6 of the sprocket 5 arranged at the tip of the separation tank 1. 10 is a chain connected by a hollow pin 10a, which is a separation tank 1
By means of the sprockets 5 arranged inside, the separation tanks 1 are arranged in parallel at predetermined intervals in the width direction of the separation tank 1 as shown in FIG. 2 and are stretched horizontally as shown in FIG.

Reference numeral 11 is a rod arranged in a saw-like shape between both chains 10-10, and both ends thereof are inserted and carried in the holes of the hollow pin 10a.

12 is a paper roll located above the tip of the separation tank 1. The paper filter 13 supplied from the paper roll 12 is placed on the rod 11 carried between the chains 10-10, and the tip of the paper filter 13 is separated from the separation tank. 1 and is guided into the bucket 15 connected to the outer surface of the rear end of the separation tank 1.

Reference numeral 16 is a paper guide in which the side surface inclined portion 16a is formed in an inverted V shape, folds 16b are formed in a convex shape, and folds 16c are formed in a concave shape, and are horizontally formed along both side surfaces of the separation tank 1. Are arranged in the same direction and are fixed by bolts 17. However, as for the paper guide 16, both side edges of the paper filter 13 whose opposite side edges are guided in an inverted C shape are sandwiched between the rod 11 and the side inclined section 16a of the paper guide 16. In order to prevent this, as shown in FIG. 2, the separation tank 1 is arranged so that the interval L gradually increases from the front end to the rear end.

Reference numeral 18 denotes a chain guide that prevents the chain 10 from slackening, and is arranged along the inner side surface of the central portion of the separation tank 1.

According to the powder particle removing device of the present invention having the above configuration,
