DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1 and Figure 2An oil-gas separation device of an oil chromatograph comprises an outer shell 1 and an oil separation core body 4. The outer shell 1 is provided with an oil inlet pipe, a collecting bucket 5 and a discharge pipe 6. The oil separation core body 4 is provided with a connecting pipe 2. The oil inlet pipe takes in oil, the collecting bucket 5 collects the oil discharged into the air, the discharge pipe 6 discharges the oil collected by the collecting bucket 5, and the connecting pipe 2 discharges the air, wherein a valve can be provided in the discharge pipe 6.

[0023] Reference Figure 2-Figure 5 A reciprocating screw 8 is rotatably provided in the outer shell 1, a driving mechanism connected to the reciprocating screw 8 is provided on the outer shell 1, a screw sleeve 10 is provided on the outer wall of the reciprocating screw 8 through a threaded sleeve of a limiting mechanism, a lifting ring 7 is provided on the screw sleeve 10, the lifting ring 7 is designed in two sections and is connected through an installation mechanism, a cleaning ring 11 is rotatably provided in the lifting ring 7, a rotating motor is provided in the lifting ring 7, and the rotating motor is connected to the cleaning ring 11 through a rotating mechanism.

[0024] The drive mechanism includes a drive motor 3 arranged on the upper end surface of the outer shell 1. The output shaft of the drive motor 3 extends into the inner part of the outer shell 1 and is fixedly connected to the end of the reciprocating screw 8. The drive motor 3 is the power device of the reciprocating screw 8 and is arranged outside for heat dissipation.

[0025] The limiting mechanism includes a limiting rod 9 arranged inside the outer shell 1, which slides through the screw sleeve 10. The limiting rod 9 and the reciprocating screw 8 are both placed vertically and designed in parallel, thereby realizing the limiting effect of the screw sleeve 10 and preventing it from rotating with the reciprocating screw 8.

[0026] The mounting mechanism includes mounting blocks 14 arranged on two sections of the lifting ring 7. The two corresponding mounting blocks 14 are connected by mounting bolts 15. The connection operation of the lifting rings 7 at both ends is realized by means of the mounting blocks 14 and the mounting bolts 15. The connection between the two ends is a sealed connection.

[0027] The rotating mechanism includes a gear 13 arranged on the end of the output shaft of the rotating motor. The arc-shaped outer wall of the cleaning ring 11 is provided with a gear ring 12 meshing with the gear 13. The gear 13 meshing with the gear ring 12 can drive the cleaning ring 11 to rotate with the help of the rotating motor.

[0028] The vertical cross-section of the accommodating cavity formed by the lifting rings 7 at both ends is T-shaped, and the vertical cross-section of the cleaning ring 11 is also T-shaped. This shape design ensures that the cleaning ring 11 can rotate inside the lifting ring 7, and the cleaning operation of the oil-separating core body 4 is achieved with the help of the cleaning brush on the arc-shaped inner wall of the cleaning ring 11. In the attached figure of this scheme, the holes on the oil-separating core body 4 are not drawn.

[0029] When the utility model is used, the oil and gas entering the outer shell 1 through the oil inlet pipe are separated through the oil separator core body 4. After being filtered, the oil flows downward along the oil separator core body 4 and is collected in the collecting bucket 5. The separated gas is discharged through the connecting pipe 2 at the upper end of the oil separator core body 4.

[0030] When the oil separator core body 4 needs to be cleaned, start the drive motor 3 and the rotating motor. The drive motor 3 can drive the reciprocating screw 8 to rotate. When the reciprocating screw 8 rotates, the screw sleeve 10 on its outer wall drives the cleaning ring 11 to move up and down relative to the oil separator core body 4 with the help of the lifting ring 7, and the rotating motor drives the cleaning ring 11 to rotate relative to the oil separator core body 4 with the help of the gear 13 and the gear ring 12, thereby realizing a comprehensive cleaning operation of the oil separator core body 4.

[0031] The disassembly operation of the two-section lifting ring 7 is achieved by removing the mounting bolts 15. After the section of the lifting ring 7 not connected to the screw sleeve 10 is removed, it is convenient to disassemble the cleaning ring 11, thereby facilitating its replacement or cleaning.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
