In addition, since specific gravity separation is performed in the process of each above-mentioned flow, it is desirable to increase the residence time in this casing A.

  The oil flows from the punching cylinder 31 → the support plate 22 and the clearance 30 between the outer peripheral plate 20a of the second casing 20 → the inner flow of the outer peripheral plate 20a of the second casing 20 → the clearance 1002 of the wall plate 10 → first. Flows on the inner surface of the outer peripheral plate 1c of the casing 1 → the gap 18 between the partition plate 4 and the outer peripheral member 8b of the double cylinder 8 → the surface portion 1b of the first casing 1 → the opening hole 300 of the oil converging portion 3 → the drain pipe 17 It is a flow. Then, the collected oil and / or chips and foreign matters are removed from the drain pipe 17.

  Also, a plurality of brackets with screw holes (not shown) are installed on the peripheral surface of the mounting plate 25, and the outer peripheral plate 20a of the second casing 20 is attached to the bracket, and at the time of this attachment, the outer peripheral plate 20a. The screw hole of the bracket and the screw hole of the bracket are aligned, a stopper is screwed into the aligned screw hole, the second casing 20 is temporarily fixed to the bracket, and a part of the oil mist collector can be released. By doing so, maintenance (ease of maintenance management, cleaning, etc.) can be performed without completely removing the second casing 20.

  In the figure, reference numeral 40 denotes an auxiliary oil mist collector provided on the side surface of the apparatus X.
