Description

Technical Field

[0001] The utility model belongs to the technical field of oil-gas separation, and more specifically, particularly relates to a novel oil-gas separator structure. Background Art

[0002] The oil-gas separator is a device that separates the crude oil and associated natural gas produced by the oil well. The oil-gas separator is placed between the submersible centrifugal pump and the protector to separate the free gas from the well fluid. The liquid is sent to the submersible centrifugal pump, and the gas is released into the annular space between the tubing and the casing.

[0003] Based on the above, the inventors have found the following problems: the oil-gas separators currently used are mainly divided into centrifugal type, dynamic pressure type, and flat plate type. The centrifugal oil-gas separator mainly uses the centrifugal action generated by the rotor to separate the gas in the oil-gas mixture. In the use of the oil-gas separator, most of the filters are installed in the oil-gas separator. However, during the long-term use of the filter, a lot of impurities will accumulate in the filter, which is inconvenient to disassemble and clean. When the impurities in the filter cannot be cleaned up in time, the impurities will accumulate in the mesh of the filter, which will make it difficult for the oil to pass through the filter again, thereby reducing the filtering effect of the filter, which is not conducive to the overall separation efficiency of the oil and gas, and reduces the use effect of the overall device.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a new oil-gas separator structure is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a novel oil-gas separator structure to solve the problem that the existing filter screen is inconvenient to disassemble.

[0006] The purpose and effect of the novel oil-gas separator structure of the utility model are achieved by the following specific technical means:

[0007] A novel oil-gas separator structure comprises a separator shell, a filter screen is arranged on the inner side of the separator shell, a mounting groove is provided on the inner side of the separator shell, a fixing piece is connected to the inner lower part of the mounting groove by a fixing screw, a transverse groove is provided on the upper part of the fixing piece, a longitudinal groove is provided on the inner upper part of the fixing piece, a limiting rod is provided in the middle part of the transverse groove, a limiting piece is installed on the lower end of the limiting rod, a connecting ear is provided on the side of the filter screen, and the limiting rod passes through the connecting ear.

[0008] Furthermore, the transverse groove and the longitudinal groove are arranged in a cross shape, the depth of the longitudinal groove is less than the thickness of the inner upper portion of the fixing member, and the transverse groove runs through the inner upper portion of the fixing member.

[0009] Furthermore, a spring is installed on the inner side of the fixing member, a lifting member is installed on the upper part of the spring, and the upper surface of the lifting member is in contact with the lower surface of the limiting member.

[0010] Furthermore, the size of the limiting member is smaller than the size of the transverse groove, and the limiting member is located inside the longitudinal groove.

[0011] Furthermore, the limiting rod is provided with a thread, and the limiting rod is connected to a nut through the thread. The nut is located on the upper part of the connecting ear and fits with the upper surface of the connecting ear. The lower surface of the connecting ear fits with the upper surface of the fixing piece.

[0012] Furthermore, an oil circuit is provided at the inner lower portion of the fixing member, and one end of the oil circuit is connected to the middle portion of the fixing member.

[0013] Furthermore, the number of the mounting grooves and the fixing members is four, and the four fixing members are respectively located on the inner side of the separator housing and are evenly arranged in a circle.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, the nut is separated from the limiting rod, the limiting rod is pressed down, the spring is contracted, and the limiting rod is rotated so that the limiting piece and the transverse groove correspond to each other. The limiting piece is pushed out from the inside of the fixing piece by the force of the spring, and then the limiting piece contacts the lower part of the connecting ear, the limiting rod is lifted upward, and the filter screen is taken out, thereby achieving the purpose of convenient disassembly.

[0016] After the limit piece and the transverse groove correspond to each other up and down in the utility model, the limit rod is pushed downward, and the limit piece passes through the transverse groove to enter the interior of the fixing piece and contacts the lifting piece. When the limit piece moves downward, the spring contracts. When the limit piece enters the interior of the fixing piece, the limit rod is rotated and the limit piece is also rotated. When the limit piece is rotated to correspond to the longitudinal groove, the limit piece can be pushed into the interior of the longitudinal groove by the force of the spring, and then the nut and the thread are matched to limit the upper part of the connecting ear, so as to facilitate the fixation of the filter screen.

A spring 6 is installed on the inner side of the fixed member 5, and a lifting member 7 is installed on the upper part of the spring 6. The upper surface of the lifting member 7 is fitted with the lower surface of the limit member 11. After the limit member 11 and the transverse groove 8 correspond to each other up and down, the limiting rod 10 is then pushed downward. The limit member 11 penetrates the transverse groove 8 and enters the interior of the fixed member 5, and contacts the lifting member 7. The limit member 11 moves downward and the spring 6 contracts. When the limit member 11 enters the interior of the fixed member 5, the limiting rod 10 is rotated and the limit member 11 is also rotated. When the limit member 11 is rotated to correspond to the longitudinal groove 9, the limit member 11 can be pushed into the interior of the longitudinal groove 9 by the force of the spring 6, and then the nut 15 and the thread 14 are matched to limit the upper part of the connecting ear 13, so that the filter screen 2 can be fixed.

[0029] The size of the limiting member 11 is smaller than that of the transverse groove 8 , and the limiting member 11 is located inside the longitudinal groove 9 .

[0030] Among them, a thread 14 is opened on the limiting rod 10, and the limiting rod 10 is connected to a nut 15 through the thread 14. The nut 15 is located at the upper part of the connecting ear 13 and fits with the upper surface of the connecting ear 13. The lower surface of the connecting ear 13 fits with the upper surface of the fixing member 5. The nut 15 and the thread 14 are matched to limit the upper part of the connecting ear 13, so that the filter screen 2 can be fixed.

At this time, the connecting ear 13 on the side of the filter screen 2 is located inside the mounting groove 3. When the connecting ear 13 continues to move downward and moves to the upper part of the fixing member 5, the limiting rod 10 is rotated. At this time, the lower limiting member 11 rotates accordingly. After the limiting member 11 and the transverse groove 8 correspond to each other up and down, the limiting rod 10 is then pushed downward.

The control rod 10 and the limit piece 11 also rotate. When the limit piece 11 rotates to correspond to the longitudinal groove 9, the limit piece 11 can be pushed into the interior of the longitudinal groove 9 by the force of the spring 6, and then the nut 15 and the thread 14 cooperate to limit the upper part of the connecting ear 13, so that the filter screen 2 can be fixed. When disassembly is required, the nut 15 is first separated from the limit rod 10, and then the limit rod 10 is pressed down, the spring 6 contracts, and the limit rod 10 is rotated to make the limit piece 11 correspond to the transverse groove 8. The limit piece 11 is pushed out from the inside of the fixing part 5 by the force of the spring 6, and then the limit piece 11 contacts the lower part of the connecting ear 13, and the limit rod 10 is lifted upward to bring the filter screen 2 out.
