The oil-containing compressed air in the super-oleophobic composite oil removal filter element forms a tiny vortex airflow and accelerates again, so that the water and oil gas in the oil-containing compressed air are separated from it and drip into the oil collection cup. The super-oleophobic composite oil removal filter element is a foamed wire mesh with a super-oleophobic and water film on the surface, so that the separated oil droplets cannot stick to the inner surface of the super-oleophobic composite oil removal filter element and drip.

The oil collecting silencer generally comprises an air intake cover of the upper connecting device, a filter silencer in the middle, and an oil collecting cup 1 at the lower side. A connecting rod is connected to the air intake cover, and the connecting rod is connected to the oil collecting cup 1 to fix the filter silencer. This is the prior art and will not be described in detail; the auxiliary oil draining part 2 is connected to the oil collecting cup 1, and the auxiliary oil draining part 2 comprises an auxiliary cylinder 21, which is connected to the oil collecting cup 1, and the auxiliary cylinder 21 has a cavity. The auxiliary cylinder 21 is connected to the oil draining cylinder 11 through a connecting pipe 22, and the connecting pipe 22 comprises a pipe body 221 and a bend The second tube body 222 is folded to form a tube body 222, which is located in the oil drain cylinder 11. The connecting tube 22 extends into the oil drain cylinder 11 and makes the outlet direction the same as the oil outflow direction of the oil drain cylinder 11. The tube body 1 221 is used to connect the auxiliary cylinder 21 and the oil drain cylinder 11. The second tube body 222 is used to drive the airflow to make the oil droplets flow out. The oil drain nut 12 includes a threaded portion 121 and an abutment portion 122 for blocking the outlet of the connecting tube 22. The threaded portion 121 is used for connection, and the abutment portion 122 is used to be inserted into the oil drain cylinder 11 to block the outlet of the connecting tube 22 to prevent oil from entering the connecting tube 22. A movable piston 23 is provided in the auxiliary cylinder 21, and the airflow enters the connecting tube 22 through the movement of the piston 23. The airflow enters from the tube body 1 221 and flows out from the tube body 222.

[0030] A rotating cylinder 24 is arranged in the auxiliary cylinder 21, a support portion 211 is arranged at the bottom of the auxiliary cylinder 21, a rotating groove 212 is provided in the support portion 211, a convex block 25 inserted into the rotating groove 212 is connected to the bottom of the cylinder 24, a piston 23 is located in the cylinder 24, the diameter of the piston 23 is adapted to the inner diameter of the cylinder 24, a circumferential synchronous member 26 is arranged between the cylinder 24 and the piston 23, the synchronous member 26 is connected to the cylinder 24, the synchronous member 26 is used for the synchronous rotation of the cylinder 24 and the piston 23, the synchronous member 26 and the piston 23 are slidably connected, a through hole 27 is arranged on the cylinder 24, and the diameter of the through hole 27 is larger than that of the tube body 2 The inner diameter of 21 is convenient for communication.

The diameter of the through hole 28 is larger than the diameter of the through hole 27, which is convenient for communication. When the piston 23 is reset to continue the air, the through hole 27 is connected with the channel 2 to inhale air from the outside. The cylinder 24 switches the communication between the through hole 27 and the through hole 28 or the tube body 221 by rotating. When the protrusion 25 moves from one end of the rotating groove 212 to the other end, the cylinder 24 completes the transmission, thereby completing the communication between the through hole 27 and the through hole 28 or the tube body 221.

[0031] It should be noted that when the cylinder 24 stores gas, the gas enters from the second through hole 28 by switching. The outlet ball of the second tube body 222 does not move, preventing the gas flow of the oil drain cylinder 11 from flowing upward.

[0034] During use, the drain nut 12 is first separated from the drain cylinder 11, and the oil flows out from the oil collecting cup 1 under the action of gravity. When the oil layer that is easy to adhere to the cup wall will slowly flow out, the through hole 1 27 is adjusted to be connected with the tube body 1 221, and the movable rod 29 is moved upward through the operating part 291. The movable rod 29 moves with the piston 23, and the piston 23 pushes the airflow into the tube body 1 221, and the airflow flows into the tube body 222 and flows out from the outlet. The outflowing airflow brings the airflow in the oil collecting cup 1 and flows out from the outlet of the drain cylinder 11. The oil in the oil collecting cup 1 flows along the airflow, which increases the outflow of the oil. The efficiency is that after the piston 23 moves to the top, the operating part 291 is rotated, and the operating part 291 causes the movable rod 29 and the piston 23 to rotate. The piston 23 causes the cylinder 24 to rotate through the synchronous part 26, and the protrusion 25 moves in the rotating groove 212. When the protrusion 25 is blocked, the through hole 1 27 is connected with the through hole 2 28, and then the operating part 291 is pulled to work the piston 23 downward, so that air is introduced into the cylinder 24. After the air intake is completed, the cylinder 24 is reset through the operating part 291, so that the through hole 1 27 is connected to the tube body 1 221 again, and the piston 23 can move up again.
