Detailed Description
As shown in fig. 1-3, the active oil return type oil-gas separator comprises a chassis 11 and a box body 13 arranged on the chassis 11, wherein a cover plate 3 is arranged at the upper end of the box body 13, the cover plate 3 is provided with an oil-gas mixture inlet 1 and an oil-gas mixture outlet 2, an inlet filter screen 4 is respectively arranged at the lower end of the cover plate 3 below the oil-gas mixture inlet 1, an outlet filter screen 7 is respectively arranged at the lower end of the cover plate 3 below the oil-gas mixture outlet 2, a baffle 5 is fixedly connected to the lower end of the cover plate 3, the baffle 5 separates the inlet filter screen 4 from the outlet filter screen 7, and the oil-gas mixture outlet 2 is prevented from being polluted by the oil. As shown in fig. 1-2, the tank 13 is provided with an oil return port 9, and the oil return port 9 is disposed below a side wall of the tank 13. The side wall of the box body 13 is provided with a liquid level mirror 10, the liquid level mirror 10 is a vertical strip-shaped transparent glass lens, and the liquid level height of oil in the box body 13 can be seen through the liquid level mirror 10. The box body 13 is also internally and longitudinally provided with a lifting rod 6, the upper end of the lifting rod 6 penetrates through the cover plate 3 and is connected with a PLC control unit 14, in the embodiment, the lifting rod 6 is a multi-stage telescopic rod, when the lifting rod 6 is required to pull up the one-way baffle 8, the PLC control unit 14 controls the lifting rod 6 to move, and the rod part close to the next stage is telescopic into the hollow cavity in the rod part close to the previous stage; when the one-way baffle 8 is required to descend, the rod part of the next level extends downwards from the hollow cavity in the rod part of the previous level. In other embodiments of the present invention, the lifting rod 6 can also be a straight rod, and the PLC control unit 14 directly controls the lifting of the straight rod. Lower extreme fixedly connected with one-way baffle 8 of lifter 6, one-way baffle 8 is connected with PLC the control unit 14 through the lead wire of burying underground in lifter 6, and in this embodiment, one-way baffle 8 is the hinge, and the hinge axle of hinge and lifter 6's lower extreme are through modes fixed connection such as welding or threaded connection, and the hinge can only be closed downwards. When oil needs to downwards pass through the one-way baffle 8, the PLC control unit 14 controls the hinge to be opened, the diameter of the hinge is the same as the inner diameter of the box body 13, therefore, when the hinge is opened, the inside of the box body 13 is just vertically separated, the one-way baffle 8 vertically separates the box body 13 into an oil separating cavity and a compression cavity, the oil separating cavity is arranged above the box body, the compression cavity is arranged below the box body, and the pressure sensor 12 is arranged in the compression cavity. The oil-gas mixture inlet 1, the oil-gas mixture outlet 2 and the oil return port 9 can be connected with respective external pipelines in a threaded connection, welding or flange connection mode, and threaded connection is adopted in the embodiment.
The utility model discloses a working method as follows:
the oil-gas mixture enters the box body 13 through the oil-gas mixture inlet 1 and is primarily filtered through the inlet filter screen 4, as shown in fig. 1, the hinge is not completely opened, lubricating oil can flow into the compression cavity through the hinge, and partial working medium gas directly flows out through the oil-gas mixture outlet 2 after the oil-separating cavity is secondarily filtered through the outlet filter screen 7. Meanwhile, the oil entering the compression chamber flows out through the oil return port. The liquid level of oil in the box body 13 can be observed through the liquid level mirror 10, when the liquid level is too high and approaches to the height of the hinge, the hinge is controlled to be opened through the PLC control unit 14, the lifting rod 6 is controlled to descend, and the height of the hinge is reduced. At this time, the pressure in the compression cavity is increased, the pressure difference with the atmospheric pressure is increased, the flow speed of oil flowing out of the oil return port 9 in the compression cavity is increased, the oil return speed is increased, the pressure value of the pressure sensor 12 is observed while the oil return speed is increased, the descending amplitude of the lifting rod 6 is adjusted according to the pressure in the compression cavity, and therefore the oil return speed is controlled. After the oil return is finished, the lifting rod 6 is lifted, so that the height of the hinge is lifted, the pressure in the compression cavity is recovered to be normal, the hinge is closed, the oil remained on the upper surface of the hinge gradually flows into the compression cavity, and the oil separation and return process is continued for the next time.
The above description is only the preferred embodiment of the present invention, but the present invention is not limited to the above-mentioned specific embodiments, and for those skilled in the art, a plurality of modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention.
