Smoke exhaust device of lubricating oil system

The utility model relates to the technical field of lubricating oil system smoke exhaust, and discloses a lubricating oil system smoke exhaust device which comprises a fixed mounting plate, a fixed support is fixedly connected to the top end of the fixed mounting plate, a smoke exhaust pipe is fixedly connected to the interior of the fixed support, and a flow guide pipe is fixedly connected to the bottom end of the smoke exhaust pipe. The bottom end of the fixed mounting plate is fixedly connected with a corrugated pipe; by arranging the circulating cooling mechanism, when the smoke exhaust pipe exhausts air to the outside, the circulating cooling mechanism can cool the smoke exhaust pipe, so that lubricating oil can be liquefied on the inner wall of the smoke exhaust pipe, and then the lubricating oil can flow into the inner side of the movable collecting box through a flow guide pipe and a corrugated pipe under the action of the gravity of the lubricating oil; therefore, lubricating oil can be collected, th
