Technical Field

[0001] This invention relates to a self-cleaning auxiliary mechanism, specifically to a self-cleaning auxiliary mechanism for an oil-gas separator. Background Technology

[0002] An oil-gas separator is a supporting device for separating oil and gas. It is needed in the process of oil and gas recovery. The oil-gas separator can effectively separate oil and gas to obtain a purer oil, which is convenient for people to use. It is simple and convenient. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of oil-gas separators.

[0003] Existing oil-gas separators have certain drawbacks in use. First, the inner wall of the reaction tank is prone to oil accumulation during oil-gas separation, making cleaning difficult, wasting oil resources, and hindering user experience. Second, the lack of filtration during oil discharge may result in impurities, reducing separation efficiency and negatively impacting user experience.

[0004] In view of this, this application designs a self-cleaning auxiliary mechanism for an oil-gas separator. Summary of the Invention

[0005] The main objective of this disclosure is to provide a self-cleaning auxiliary mechanism for an oil-gas separator, so as to effectively solve the problems raised by the inventors in the above-mentioned background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A self-cleaning auxiliary mechanism for an oil-gas separator includes an upper processor and a lower separator. The bottom of the lower separator is fixedly mounted with a lower support leg. The bottom outlet of the upper processor is fixedly connected to the top inlet of the lower separator. A cleaning shaft is rotatably mounted inside the upper processor, and three positioning rings are fixedly mounted on the cleaning shaft at equal intervals from top to bottom. Each positioning ring is movably connected to a plurality of brush rods arranged in a circular array on its side. Each brush rod is movably connected to a cleaning brush, and the cleaning brush faces the inner wall of the upper processor. The lower separator is equipped with a first separation filter and a second separation filter inside, with the first separation filter located above the second separation filter. Both separation filters are movable, and the pore size of the first separation filter is larger than that of the second separation filter. An extraction mechanism is installed on the side of the lower separator.

[0007] Preferably, the brush rod has a groove inside, and a telescopic rod is slidably installed in the groove. One end of the telescopic rod extends outside the brush rod and is fixedly connected to the cleaning brush. A return spring is fixedly connected to the bottom of the groove, and the other end of the return spring is fixedly connected to the telescopic rod.

[0008] Preferably, the positioning ring has a notch on its side, and a swing pin is rotatably installed in the notch. One end of the brush rod is fixedly installed on the swing pin, and a ring-shaped tension spring is fixedly connected between two adjacent brush rods.

[0009] Preferably, a feed pipe is fixedly installed on the top of the upper processor, and a docking flange is fixedly connected to the bottom end of the feed pipe. A mounting plate is fixedly sleeved on the surface of the feed pipe, and a working motor is fixedly installed at the bottom of the mounting plate. The output end of the working motor is fixedly connected to the cleaning shaft.

[0010] Preferably, the extraction mechanism includes an extraction cylinder, an injection pipeline, a discharge pipe, and a first manual valve. Two extraction cylinders are fixedly installed on the side of the lower separator, and the two extraction cylinders are arranged vertically. An injection pipeline is fixedly connected to the extraction cylinder, and the other end of the injection pipeline is fixedly connected to the lower separator. A discharge pipe is fixedly connected to the bottom of the extraction cylinder, and a first manual valve is installed on the discharge pipe.

[0011] Preferably, the inner wall of the lower separator is fixedly installed with two annular clamping plates arranged vertically. Each annular clamping plate has several sliders slidably installed inside it. The first separation filter is fixedly connected between several sliders in the upper annular clamping plate, and the second separation filter is fixedly connected between several sliders in the lower annular clamping plate. A guide hopper is fixedly installed on the top of each of the two annular clamping plates, and the guide hopper leads to the separation filter. The two extraction cylinders correspond to the first separation filter and the second separation filter, respectively.

[0012] Preferably, a linkage block is fixedly connected to the side of the slider, and the linkage block slides in the side plate slide of the lower separator. A reciprocating rail is fixedly installed on the outer side of the lower separator, and a Y-axis one-way lead screw is rotatably installed inside the reciprocating rail. A movable through rod is threaded on the Y-axis one-way lead screw, and the movable through rod slides through and is connected to the reciprocating rail. Linkage blocks with vertically distributed positions are fixedly connected to both ends of the movable through rod. A servo motor is fixedly installed on the outer side of the reciprocating rail, and a drive gear is fixedly connected to the output end of the servo motor. One end of the Y-axis one-way lead screw extends to the outside of the reciprocating rail and is fixedly connected to a reduction gear, and the reduction gear meshes with the drive gear.

[0013] Preferably, a discharge pipe assembly is fixedly connected to the bottom of the lower separator, and a second manual valve is installed on the discharge pipe assembly.

[0014] In view of this, compared with the prior art, the beneficial effects of the present invention are: (i) In this application, during the separation process, when the working motor is started, the cleaning shaft drives the positioning ring to rotate, causing the brush rod to rotate, thereby agitating the material to improve the efficiency of subsequent separation. During this period, under the action of centrifugal force, the cleaning brush will drive the telescopic rod to slide away from the cleaning shaft, and the return spring will be stretched until the cleaning brush contacts the inner wall of the upper processor and moves to clean it, preventing material from adhering to the inner wall of the upper processor and facilitating the cleaning task after use, thus achieving the purpose of self-cleaning during the working process.

[0015] (ii) In this application, after the stirring is finished, the cleaning shaft drives the positioning ring to stop moving. However, due to inertia, the brush rod will continue to move. Due to the movable installation of the swing pin, the brush rod will continue to move. Under the obstruction of the annular tension spring and the material, the brush rod will move irregularly or even shake, so as to discharge the material on it to a greater extent. The effect is excellent.

[0016] (III) In this application, the first separation filter and the second separation filter separate the materials, while the extraction cylinder can separate oil and gas. During the material separation, the servo motor is started, causing the Y-axis unidirectional screw to rotate, and then the moving rod moves back and forth along the reciprocating rail, causing the linkage block to drive the slider to move. In turn, the first separation filter and the second separation filter move back and forth, which disperses the accumulated materials and avoids blockage. On the other hand, it allows different positions of the separation filter to participate in the separation task, improving the smoothness. Attached Figure Description

Two extraction cylinders 16 are fixedly installed on the side of the lower separator 2, and the two extraction cylinders 16 are arranged vertically.

A discharge pipe assembly is fixedly connected to the bottom of the lower separator 2, and a second manual valve 19 is installed on the discharge pipe assembly.

[0024] Specifically, two annular clamping plates 20 arranged vertically are fixedly installed on the inner wall of the lower separator 2. Several sliders 21 are slidably installed within each annular clamping plate 20.

The effect is excellent. The first separating filter screen 22 and the second separating filter screen 23 separate the materials, while the extraction cylinder 16 can perform oil and gas separation. During the material separation, the servo motor 30 is started, causing the Y-axis unidirectional lead screw 28 to rotate, and then the moving rod 26 moves back and forth along the reciprocating rail 25, causing the linkage block 27 to drive the slider 21 to move. In turn, the first separating filter screen 22 and the second separating filter screen 23 move back and forth, which on the one hand disperses the accumulated materials to avoid blockage, and on the other hand allows different positions of the separating filter screens to participate in the separation task, improving the smoothness.
