Description

Technical Field

[0001] This utility model belongs to the field of lubrication equipment technology, and specifically relates to an oil-gas separation device. Background Technology

[0002] In the traditional machinery industry, moving parts in equipment require grease or lubricating oil to lubricate their surfaces and prevent wear. However, regardless of whether it's grease or oil lubrication, over time, some grease or oil will inevitably leak from the moving parts. This not only pollutes the environment but can also affect product quality. While grease leaks are easy to wipe up, oil leaks are difficult to collect and tend to seep into the surrounding area, creating a poor working environment.

[0003] The current method for dealing with leaked thin oil lubricant is to use negative pressure to absorb the oil vapor and then discharge the extracted oil vapor into a waste oil drum, which is cleaned regularly. However, this method will cause stains all over the ground around the waste oil drum, which is not conducive to environmental protection in the workplace. Furthermore, after thin oil leaks from the production equipment, it is necessary to add lubricant to the moving parts frequently, otherwise the equipment oil tank will quickly run out of oil, leading to lubrication failure. Utility Model Content

[0004] The purpose of this invention is to provide an oil-gas separation device that can recover and reuse leaked lubricating oil from equipment, which can not only improve the working environment but also save on the use of lubricating oil.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An oil-gas separation device includes an upper chamber and a lower chamber arranged in an overlapping manner. A first partition is provided between the upper chamber and the lower chamber. The first partition is provided with an oil drain hole and a connecting piece connecting the upper chamber and the lower chamber. The lower chamber is provided with an oil suction port, an air inlet, and an oil drain port. An air inlet pipe is provided in the lower chamber and communicates with the air inlet. The end of the air inlet pipe away from the air inlet is connected to a vacuum generator. The outlet end of the vacuum generator is connected to an oil drain pipe. An oil suction pipe is connected to the oil suction port and communicates with the vacuum generator. The end of the oil drain pipe away from the vacuum generator is connected to the connecting piece. An exhaust pipe is provided on the upper chamber, and a second partition is provided in the upper chamber at the exhaust pipe location.

[0007] Furthermore, the vacuum generator includes a vacuum generator body, a connecting channel is provided inside the vacuum generator body, the inlet of the connecting channel is a compressed air inlet, the air inlet pipe is connected to the compressed air inlet, the outlet of the connecting channel is an air outlet, the air outlet is connected to the oil drain pipe, a nozzle is provided in the connecting channel with the spray direction aligned with the air outlet, and a vacuum suction port is provided on the vacuum generator body located in the spray direction of the nozzle, the vacuum suction port is connected to the oil suction pipe. This technical solution is configured such that the air inlet on the lower housing is connected to an external compressed air source. The compressed air enters the connecting channel at high speed from the compressed air inlet on the vacuum generator and is ejected at high speed from the nozzle, thus creating a partial vacuum at the nozzle outlet, i.e., a vacuum at the vacuum suction inlet. Because the vacuum suction inlet is connected to the oil suction pipe, a vacuum is created at the oil suction pipe inlet. The oil suction pipe inlet can generally be connected to the oil leakage point that needs to be suctioned through an external pipe. The oil leaking from the equipment is then absorbed into the oil suction pipe through negative pressure, and finally, together with the compressed air ejected from the nozzle, they form oil vapor, which enters the oil discharge pipe through the air outlet; thus achieving the purpose of oil suction.

[0008] Furthermore, the connecting component is a muffler. The connecting component in this technical solution is a muffler. The muffler not only disperses the oil and gas, achieving better separation, but also reduces the noise of the high-speed oil and gas flow as it passes through the muffler.

[0009] Furthermore, the muffler is a copper muffler with a height of 25-35mm. Experiments have shown that copper mufflers offer better oil-gas dispersion compared to mufflers made of other materials (such as rubber mufflers). Additionally, the lower height of the copper muffler (25-35mm) avoids obstructing the oil-gas separation process, resulting in better separation.

[0010] Furthermore, the lower housing has a conical structure that is wider at the top and narrower at the bottom, with the oil drain port located at the lowest point of the lower housing. This design allows the liquid oil after oil-gas separation to enter the bottom of the conical lower housing, then flow out through the drain port and back into the equipment's oil tank via a pipeline.

[0011] Furthermore, two vacuum generators are installed inside the lower housing, located on both sides of the lower housing. Four connecting members are arranged in a square array on the first partition. A tee pipe is installed on the oil drain pipe, and the outlet end of the tee pipe is connected to one of the connecting members. This arrangement allows the oil-gas separation device of this invention to be more efficient and have a more compact structure.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] This utility model features an air inlet on the lower housing that connects to external compressed air. The compressed air enters the connecting channel at high speed from the compressed air inlet on the vacuum generator and is ejected at high speed from the nozzle, creating a partial vacuum at the nozzle outlet, i.e., a vacuum at the vacuum suction inlet. Because the vacuum suction inlet is connected to the oil suction pipe, a vacuum is created at the oil suction pipe inlet. The oil suction pipe inlet can generally be connected to the leaking oil location via an external pipe. The leaking oil is then absorbed into the oil suction pipe by negative pressure, finally mixing with the compressed air ejected from the nozzle to form oil vapor, which enters the oil discharge pipe through the air outlet. The oil vapor then flows through the oil discharge pipe... After entering the silencer and undergoing initial oil-gas separation, the oil and gas enter the upper chamber. High-pressure oil and gas collide on the three side walls and the second partition of the upper chamber, causing the oil and gas to swirl and collide centrifugally within the upper chamber. The liquid portion of the oil then settles at the bottom of the lower chamber and enters through the drain hole, finally flowing out from the bottom drain port of the conical lower chamber. This oil then flows back into the equipment's oil tank via a pipeline, while the separated gas is discharged through the exhaust pipe. This entire process allows for the recovery and reuse of leaked lubricating oil, improving the working environment and saving on lubricating oil usage. Attached Figure Description

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0024] An oil-gas separation device according to this embodiment, such as Figure 1-6 As shown, the device includes an upper housing 1 and a lower housing 2 that are stacked together. The upper housing 1 and the lower housing 2 are fixedly connected by fastening bolts 9. A first partition is provided between the upper housing 1 and the lower housing 2. The first partition is provided with an oil drain hole 14 and a connecting piece 4 that connect the upper housing 1 and the lower housing 2. The lower housing 2 is provided with an oil suction port 6, an air inlet port 7 and an oil drain port 8. An air inlet pipe 13 connected to the air inlet port 7 is provided inside the lower housing 2. The end of the air inlet pipe 13 away from the air inlet port 7 is connected to a vacuum generator 10. The outlet end of the vacuum generator 10 is connected to the oil drain pipe 11, and the oil suction port 6 is connected to the oil suction pipe 12, which is connected to the vacuum generator 10. The end of the oil drain pipe 11 away from the vacuum generator 10 is connected to the connecting piece 4. An exhaust pipe 3 is provided on the upper box 1, and a second partition 5 is provided inside the upper box 1 at the exhaust pipe 3. In order to facilitate the return of the liquid oil after oil-gas separation to the oil tank of the equipment, the lower box 2 has a conical structure that is larger at the top and smaller at the bottom, and the oil drain port 8 is located at the lowest position of the lower box 2.

[0025] The vacuum generator 10 of this embodiment includes a vacuum generator body 101. A connecting channel 102 is provided inside the vacuum generator body 101. The inlet of the connecting channel 102 is a compressed air inlet 103. An air inlet pipe 13 is connected to the compressed air inlet 103. The outlet of the connecting channel 102 is an air outlet 104. The air outlet 104 is connected to the oil drain pipe 11. A nozzle 105 is provided inside the connecting channel 102 with its spray direction aligned with the air outlet 104. A vacuum suction port 106 is provided on the vacuum generator body 101 located in the spray direction of the nozzle 105. The vacuum suction port 106 is connected to the oil suction pipe 12. In this technical solution, the air inlet 7 on the lower housing 2 is connected to an external compressed air source. The compressed air enters the connecting channel 102 at high speed from the compressed air inlet 103 on the vacuum generator 10 and is ejected at high speed from the nozzle 105, thereby creating a partial vacuum at the outlet of the nozzle 105, i.e., a vacuum is formed at the vacuum suction port 106. Since the vacuum suction port 106 is connected to the oil suction pipe 12, a vacuum will be formed at the oil suction port 6. The oil suction port 6 can generally be connected to the oil leakage point that needs to be suctioned through an external pipe. The oil leaking from the equipment is absorbed into the oil suction pipe 12 through negative pressure, and finally, together with the compressed air ejected from the nozzle 105, they form oil vapor, which enters the oil discharge pipe 11 through the air outlet 104; thereby achieving the purpose of oil suction. To improve the oil-gas separation efficiency, two vacuum generators 10 are installed inside the lower housing 2 in this embodiment. The two vacuum generators 10 are located on both sides of the lower housing 2. There are four connecting parts 4. The four connecting parts 4 are installed in a square array on the first partition. A three-way pipe 15 is installed on the oil drain pipe 11. The outlet end of the three-way pipe 15 is connected to the connecting part 4.

[0026] In this embodiment, the connecting component 4 is a copper muffler with a height of 25-35mm. The connecting component 4 in this technical solution is a muffler. The muffler not only disperses the oil and gas, achieving better separation, but also reduces the noise of the high-speed oil and gas flow as it passes through. Experiments have shown that copper mufflers have better oil and gas dispersion than mufflers made of other materials (such as rubber mufflers, which require a height of 70mm). Furthermore, the copper muffler, with its lower height of 25-35mm, avoids obstructing the oil and gas separation during its passage, resulting in better separation.

[0027] The operating principle of the oil-gas separator in this embodiment is as follows:

[0028] The air inlet 7 on the lower housing 2 of this invention is connected to external compressed air. The compressed air enters the connecting channel 102 at high speed from the compressed air inlet 103 on the vacuum generator 10, and is ejected at high speed from the nozzle 105, thereby creating a partial vacuum at the outlet of the nozzle 105, i.e., a vacuum is formed at the vacuum suction port 106. Since the vacuum suction port 106 is connected to the oil suction pipe 12, a vacuum is formed at the oil suction port 6. The oil suction port 6 can generally be connected to the oil leakage point that needs to be suctioned through an external pipe. The oil leaking from the equipment is absorbed into the oil suction pipe 12 through negative pressure, and finally, together with the compressed air ejected from the nozzle 105, it forms oil vapor, which enters the oil discharge pipe through the air outlet 104. 11; The oil and gas then enter the silencer through the oil drain pipe 11. After silencing and preliminary oil-gas separation, they enter the upper chamber 1. The high-pressure oil and gas collide on the three side walls and the second partition 5 of the upper chamber 1, causing the oil and gas to swirl and collide centrifugally within the upper chamber 1. Finally, the liquid oil settles downward to the bottom of the lower chamber 2 and enters the lower chamber 2 through the oil drain hole 14. Finally, it flows out from the bottom oil drain port 8 of the conical lower chamber 2 and can flow back into the oil tank of the equipment through the pipeline. The separated gas is discharged through the exhaust pipe 3. The whole process can recover and reuse the lubricating thin oil leaked from the equipment, which can not only improve the working environment but also save the use of lubricating thin oil.
