[0002] In the process of industrial production and mechanical operation, oil and gas often mix. The traditional oil and gas separation method is to separate oil and gas from the oil and gas mixture. This separation method requires sufficient space for the equipment to prevent the oil and gas separation device from entering the liquid, otherwise it will cause the oil and gas separation device to be blocked, causing a sudden increase in exhaust gas pressure and oil dripping or spraying. Therefore, the traditional oil and gas separation device cannot be used in a small space and large oil volume environment. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an oil-gas separation device and a manufacturing method for use in a small space and large oil volume environment. By setting a deflection structure in the oil circuit, the flow direction of the engine oil is deflected so that the engine oil and exhaust gas are diverted to achieve rapid separation of oil and gas, thereby solving the problem of oil-gas separation in a small space and large oil volume environment.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: An oil-gas separation device for use in a small space and large oil volume environment comprises a first frame and a second frame arranged in parallel; a plurality of semicircular arc-shaped beams are arranged between the first frame and the second frame, and a curved deflection plate is obliquely arranged on the beam; a cover plate is arranged on the upper part of the top beam, and a baffle is arranged between the upper part of the cover plate and the first frame and the second frame; and no deflection plate is arranged on the bottom beam.

[0005] The further improvement of the technical solution of the present invention is that: the length of the deflection plate is 20 mm; the array distance of the deflection plates installed on the crossbeam is 15 mm; each deflection plate overlaps the previous deflection plate by 5 mm.

[0006] A further improvement of the technical solution of the present invention is that the curved surface of the deflection plate is in a bell-mouth shape.

[0008] The further improvement of the technical solution of the present invention is that: the distance between every two cross beams is 10 mm; the height of the cross beam is 5 mm, and the arc length is 230 mm. A further improvement of the technical solution of the present invention is that the first frame, the second frame and the crossbeam are integrally stamped and formed.

[0009] A further improvement of the technical solution of the present invention is that the deflection plate is welded to the outer side of the lower end of the crossbeam.

[0010] A further improvement of the technical solution of the present invention is that the first frame, the second frame, the crossbeam, the deflection plate, the cover plate and the baffle are all made of 1 mm thick thin steel plates.

[0011] A further improvement of the technical solution of the present invention is that a plurality of bolt holes are provided on both the first frame and the second frame.

[0012] A method for manufacturing an oil-gas separation device for use in a small space and large oil volume environment comprises the following steps: Step 1, designing the size of the oil-gas separation device according to the size of the oil chamber of the equipment where the oil-gas separation device is to be installed; Step 2, measuring the required thin steel plates, and integrally stamping and forming the first frame, the second frame and the arc panel; Step 3, cutting the first frame and the second frame according to the shape of the oil chamber, and punching bolt holes; Step 4, punching the arc panel according to size requirements to form a number of beams; Step 5, measuring the amount of thin steel plate required for the deflection plate, cutting the material, and then rolling it into shape; Step 6, welding the roll-formed deflector plate to the outer side of the lower end of the beam; Step 7, making a cover plate and a baffle and welding them between the top crossbeam and the first frame and the second frame; Step 8: Sand, paint and let dry.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is: 1. The oil-gas separation device provided by the present invention can be installed in the oil cavity of a device with a small space and a large amount of oil.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0022] The present invention is further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1-3 As shown, an oil-gas separation device for use in a small space and large oil volume environment comprises a first frame 1 and a second frame 6 arranged in parallel; a plurality of semicircular arc-shaped beams 3 are arranged between the first frame 1 and the second frame 6, and a curved deflection plate 4 is obliquely arranged on the beam 3; a cover plate 2 is arranged on the upper part of the top beam 3, and a baffle 5 is arranged between the upper part of the cover plate 2 and the first frame 1 and the second frame 6; and the deflection plate 4 is not arranged on the bottom beam 3.

[0023] Specifically, the deflection plate 4 is not provided on the bottom crossbeam 3, firstly, so as not to interfere with the oil-gas separation, and secondly, so as not to affect the flow of the deflection plate 4. The cover plate 2 and the baffle plate 5 are provided to adapt to the structure of the equipment oil chamber, and the top end needs to form a closed structure with the equipment oil chamber. The first frame 1 and the second frame 6 are fixed in the equipment oil chamber with screws. Figure 8 shown.

[0024] Furthermore, the length of the deflection plate 4 is 20 mm; the array distance of the deflection plates 4 installed on the crossbeam 3 is 15 mm; and each deflection plate 4 overlaps the previous deflection plate 4 by 5 mm.

[0025] Furthermore, the curved surface of the deflection plate 4 is in the shape of a bell mouth. Since the axis of the bell is one, the rotation axis of the deflection plate 4 is also one.

[0026] Furthermore, the arc length of the curved surface of the deflection plate 4 is 115 mm, the diameter of the inner circle is 214 mm, the diameter of the outer circle is 240 mm, and the angle between the spatial curved surface formed by the inner and outer edges and the rotation axis is 45°.

[0027] Furthermore, the distance between every two cross beams 3 is 10 mm; the height of the cross beam 3 is 5 mm, and the arc length is 230 mm. Furthermore, the first frame 1, the second frame 6 and the crossbeam 3 are integrally stamped and formed.

[0028] Furthermore, the deflection plate 4 is welded to the outer side of the lower end of the crossbeam 3 .

[0029] Furthermore, the first frame 1, the second frame 6, the crossbeam 3, the deflection plate 4, the cover plate 2 and the baffle 5 are all made of 1 mm thick thin steel plates; porous materials, filters or other materials that can promote gas separation can also be used.

[0030] Furthermore, a plurality of bolt holes 7 are provided on the first frame 1 and the second frame 6 .

[0031] The oil-gas separation device provided by the present invention for use in a small space and large oil volume environment can be installed on any equipment, can separate gas from oil, solve the oil-gas separation in a small space and large oil volume environment, and can be adaptively adjusted according to different equipment needs to effectively reduce the oil level. The installation surface (first frame 1 and second frame 6, etc.) of the oil-gas separation device should be adjusted according to the interface of the oil cavity of the equipment to be installed, and the number of deflection plates 4 should also be adjusted according to the size of the interface, and the shape and angle of the deflection plate 4 remain unchanged. It can also be adjusted and optimized according to different oil properties and gas components, and has a wide range of adaptability.

[0032] like Figure 4-6As shown, a method for manufacturing an oil-gas separation device for use in a small space and large oil volume environment comprises the following steps: Step 1, designing the size of the oil-gas separation device according to the size of the oil chamber of the equipment where the oil-gas separation device is to be installed; Step 2, measuring the required thin steel plates, and integrally stamping and forming the first frame 1, the second frame 6 and the arc panel; Step 3, cutting the first frame 1 and the second frame 6 according to the shape of the oil chamber, and punching bolt holes 7; like Figure 1-8 The oil-gas separation device shown is used to be installed in the cover plate cavity (oil cavity) of the vertical axis outboard engine body to separate the engine exhaust gas and the engine oil. A notch 8 is provided at the upper end of the second frame 6 to ensure the suitability of the installation.

[0033] Step 4, punching the arc panel according to size requirements to form a plurality of beams 3; When punching the arc panel, a connecting plate 12 for installing the baffle 5 needs to be left on the upper part to adapt to the structure of the equipment oil chamber, and the top end needs to form a closed structure with the equipment oil chamber.

[0034] Step 5, measuring the amount of thin steel plate required for the deflection plate 4, cutting the material, and then rolling it into shape; Step 6, welding the roll-formed deflector plate 4 to the outer side of the lower end of the beam 3; Step 7, making a cover plate 2 and a baffle plate 5 and welding them between the top crossbeam 3 and the first frame 1 and the second frame 6; Step 8: Sand, paint and let dry.

[0035] The principle is explained as follows: The oil-gas separation device for a small space and large oil volume environment (hereinafter referred to as the oil-gas separation device) provided by the present invention realizes the function of directly separating gas from oil through the structural design of the deflection plate 4, which is different from the traditional separation method from oil-gas mixture. The oil-gas separation device can effectively guide the flow direction of the oil to deflect, and in the deflection process, the gas is separated from the oil by using physical principles, and the liquid-gas diversion is realized, thereby improving the oil-gas separation efficiency.

[0036] (1) Mechanism to guide the deflection of oil flow direction A specific deflection structure is set inside the oil-gas separation device, which can change the direction of the oil during the flow. This deflection structure design causes the gas and oil to have different movement trajectories in a specific area, thereby achieving oil-gas separation. The use of the baffle deflection mechanism can directly achieve the diversion of oil and gas in the sprayed oil environment, thereby solving the problem of oil-gas separation in a small space.

[0037] (2) Advantages of directly separating gas from oil: a. Compared with the traditional separation of oil and gas mixture, the deflection structure design can directly change the direction of oil and gas movement, and can directly separate gas from oil. It avoids the need for the equipment to reserve a large space for oil and gas to settle, reduces the size of the equipment, and improves the economic value.

[0038] b. It can optimize the design according to specific oil properties and gas components to improve the pertinence and accuracy of separation.

[0039] (3) Gas separation process: a. When the oil flows and deflects in the oil-gas separation device, the gas separates from the oil due to its physical properties. The lighter gas gradually rises, while the heavier oil continues to flow and is discharged through a specific outlet.

[0040] b. The deflection structure inside the oil-gas separation device can adopt porous materials, filters or other designs that can promote gas separation to ensure the stability and reliability of the separation effect.

[0041] In practical applications, the oil-gas separation device is installed in the equipment that needs to separate oil and gas. Figure 7 , 8 As shown, the oil-gas separation device is installed in the cover plate cavity (oil cavity) of the vertical axis outboard engine body to separate the engine exhaust gas and the engine oil. The cover plate cavity (oil cavity) is set on the front side of the vertical axis engine crankshaft 9. The engine oil splashes into the cover plate cavity through the movement of the crankshaft connecting rod mechanism. Under the action of the deflection plate 4 with a deflection guide function, the flow direction of the oil is deflected. As the engine oil flows, the gas is separated from the engine oil under the influence of the engine exhaust gas pressure and discharged through the special gas outlet 10. During the oil-gas separation process, there is no liquid engine oil in the transition cavity 11. The separated engine oil flows out of the cover plate cavity with speed under the action of the deflection guide and continues to participate in the circulation of the vertical axis outboard engine oil supply system.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
