Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to a vacuum oil-water separation device. Background Technology

[0002] A vacuum oil-water separator is a separation device used to separate impurities such as water and oil from compressed air.

[0003] In existing vacuum oil-water separators, the heating element is located only at the bottom of the tank, resulting in a lower temperature at the top of the tank. Consequently, when water vapor comes into contact with the top of the tank, condensation occurs inside the tank. As the condensation accumulates, it drips into the oil, thus prolonging the oil-water separation operation time and reducing the dehydration efficiency. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a vacuum oil-water separation device, including a dehydration tank 1, with an exhaust pipe 2 fixedly connected to the top of the dehydration tank 1 and communicating with the inside of the dehydration tank 1. It can be connected to a vacuum pump to perform vacuum treatment on the inside of the dehydration tank 1, and at the same time, it can extract the water vapor inside the dehydration tank 1 to achieve the separation of water and oil inside the dehydration tank 1.

[0027] The surface of the dehydration tank 1 is fixedly connected to the injection pipe 4, which communicates with the interior, to inject the oil-water mixture to be separated into the dehydration tank 1. The bottom of the dehydration tank 1 is fixedly connected to the discharge pipe 5, which communicates with the interior of the dehydration tank 1, to discharge the processed oil. The exhaust pipe 2, injection pipe 4 and discharge pipe 5 are all equipped with valves. This is a conventional technical method, so it will not be discussed in detail here.

[0028] The surface of the dehydration tank 1 is inlaid with an observation window 3, which allows the staff to understand the separation status of the oil-water mixture inside the dehydration tank 1. A conical ring shell 10 is fixedly connected to the inner top wall of the dehydration tank 1. The conical ring shell 10 is hollow, which increases the space for the installation of subsequent structures. A shielding cap 9 is mounted on the surface of the conical ring shell 10. The shielding cap 9 can block water droplets dripping from the inner top wall of the dehydration tank 1, preventing water from mixing with oil again, thereby improving the oil-water separation efficiency of the device.

[0029] An installation ring 15 is fixedly connected to the inner wall of the dehydration tank 1. The bottom of the installation ring 15 is fixedly connected to the bottom of the conical ring shell 10. A heating ring 14 is fixedly connected inside the installation ring 15 to heat the oil-water mixture inside the dehydration tank 1 and to heat the conical ring shell 10 at the same time. This prevents water from condensing after evaporation and dripping back into the oil, thus reducing the oil-water separation efficiency.

[0030] Multiple heating rods 11 are fixedly connected to the surface of the heating ring 14. The heating rods 11 penetrate the surface of the mounting ring 15 and are fixedly connected to the interior of the mounting ring 15. Some of the heating rods 11 are located in the conical ring shell 10 to heat the conical ring shell 10, and some of the heating rods 11 are located below the conical ring shell 10 to heat the air below the conical ring shell 10. This avoids the situation where water vapor is drawn out of the dehydration tank 1 and comes into contact with the conical ring shell 10 to generate condensate. This ensures that condensate can only be generated between the conical ring shell 10 and the inner top wall of the dehydration tank 1, avoiding the re-mixing of oil and water and improving the oil-water separation effect.

[0031] The dehydration tank 1 is equipped with a heating rod 12. The end of the heating rod 11 away from the mounting ring 15 is fixedly connected to the surface of the heating rod 12 to fix the heating rod 12 in the dehydration tank 1. At the same time, the heating rod 12, the heating rod 11 and the heating ring 14 are connected together, so that the heating rod 12, the heating rod 11 and the heating ring 14 can be controlled by a single power source, avoiding cumbersome operation of the equipment. The heating rod 12, the heating rod 11 and the heating ring 14 are all equipped with heating wires. The heating wires heat the heating rod 11, the heating rod 12 and the heating ring 14 to generate heat, which heats and keeps the oil-water mixture warm. This is a conventional technical method, so it will not be discussed in detail here.

[0032] A drive motor 6 is fixedly connected to the bottom of the dehydration tank 1. The output end of the drive motor 6 passes through the surface of the dehydration tank 1 and is rotatably connected to the inside of the dehydration tank 1. A rotating sleeve 13 is fixedly connected to the output end of the drive motor 6. The inner wall of the rotating sleeve 13 slides against the surface of the heating rod 12. The surface of the rotating sleeve 13 is provided with through grooves 20 arranged at equal intervals, so that the heat generated by the heating rod 12 can be transferred to the inside of the dehydration tank 1 through the through grooves 20 to heat the oil-water mixture inside the dehydration tank 1. A connecting rod 19 is rotatably connected to the inner wall of the through groove 20. A counterweight ball 21 is fixedly connected to the lower end of the connecting rod 19. By setting the counterweight ball 21, when the rotating sleeve 13 rotates, the centrifugal force generated by the synchronous rotation of the counterweight ball 21 can drive the connecting rod 19 to rotate in the through groove 20, thereby opening the connecting rod 19 and allowing the connecting rod 19 to stir the oil-water mixture inside the dehydration tank 1, so that the oil-water mixture can be fully heated, thereby improving the efficiency of oil-water separation.

[0033] An oil scraper ring 22 is movably fitted onto the surface of the rotating sleeve 13. The inner walls of the upper end and bottom of the oil scraper ring 22 are both conical, thereby reducing the amount of oil stuck on the oil scraper ring 22. At the same time, by setting the oil scraper ring 22, when the rotating sleeve 13 stops rotating, the oil scraper ring 22 can automatically slide down on the rotating sleeve 13 under its own weight, thereby scraping off the oil adhering to the surface of the rotating sleeve 13, reducing the amount of oil adhering in the dehydration tank 1, thereby reducing oil loss and improving the use effect of the device.

[0034] The inner wall of the dehydration tank 1 is provided with two scraper blades 7, both of which have triangular cross sections. The surface of the scraper blades 7 is in contact with the inner wall of the dehydration tank 1 to scrape off the oil adhering to the inner wall of the scraper blades 7, reducing unnecessary loss and waste of oil. The upper end of the scraper blades 7 is slidably connected to the bottom of the mounting ring 15. An extension plate 8 is slidably connected to the upper surface of the scraper blades 7. A sliding plate 17 is fixedly connected to the side of the extension plate 8 near the scraper blades 7. The surface of the sliding plate 17 is slidably connected to the inside of the scraper blades 7. A spring 18 is fixedly connected between the sliding plate 17 and the scraper blades 7 to reset the extension plate 8.

[0035] The bottom of the mounting ring 15 is fixedly connected to protrusions 16 arranged at equal intervals that can drive the spring 18 to move. Both sides of the protrusions 16 are bevels.

[0036] Working principle: When separating an oil-water mixture, the mixture is injected into the dehydration tank 1 through the injection pipe 4. The liquid level should not exceed half of the dehydration tank 1. Then, the heating function is activated, causing the heating ring 14, heating rod 11, and heating bar 12 to work, heating the conical ring shell 10 and the oil-water mixture. After reaching a certain temperature, the temperature is maintained. Subsequently, a vacuum is created inside the dehydration tank 1 through the exhaust pipe 2, causing the water inside the tank to boil and turn into water vapor. Simultaneously, the water vapor is extracted through the exhaust pipe 2 under vacuum. A condenser can be connected to condense and recover the water vapor. This is a conventional technique in this field. In the dehydration tank 1, as water vapor rises, it enters the space between the conical annular shell 10 and the heating rod 11 through the through-hole of the conical annular shell 10, and is then extracted through the exhaust pipe 2. Since the conical annular shell 10 is at a high temperature at this time, the water vapor will not condense when it comes into contact with the conical annular shell 10. When the water vapor comes into contact with the inner top wall of the dehydration tank 1 and condenses, it will not drip back into the oil below due to the obstruction of the shielding cap 9. Instead, it will slide along the conical surface of the conical annular shell 10 and then be evaporated again by the high temperature of the conical annular shell 10 before being discharged through the exhaust pipe 2. Thus, the device avoids repeated separation of water and improves the oil-water separation efficiency.

[0037] Secondly, when the drive motor 6 is started, the drive motor 6 drives the rotating sleeve 13 to rotate, thereby causing the counterweight ball 21 to rotate. Under the action of centrifugal force, the counterweight ball 21 gradually moves away from the rotating sleeve 13, causing the connecting rod 19 to rotate in the through groove 20. This causes the connecting rod 19 to open, allowing it to stir the oil-water mixture in the dehydration tank 1, achieving more uniform heating of the oil-water mixture, accelerating the boiling and evaporation of water, and improving the separation efficiency of the oil-water mixture. When the top connecting rod 19 opens, the extension plate 8 blocks the rotation of the top connecting rod 19 and the counterweight ball 21, causing the connecting rod 19 and the counterweight ball 21 to push the extension plate 8 as they rotate. This causes the scraper 7 to scrape the inner wall of the dehydration tank 1, further stirring the oil-water mixture or removing the residue adhering to the dehydration tank 1. The oil on the inner wall is scraped off to reduce oil waste. As the scraper 7 and the extension plate 8 rotate in the dehydration tank 1, the extension plate 8 gradually comes into contact with the protrusion 16, causing the protrusion 16 to squeeze and push the extension plate 8. This causes the slide plate 17 to slide in the scraper 7 and stretch the spring 18. After the extension plate 8 separates from the protrusion 16, the extension plate 8 returns to its original shape. During the rotation, the extension plate 8 continuously impacts the scraper 7, thereby accelerating the dripping of oil from the scraper 7 and reducing oil waste. After the device stops operating, the counterweight ball 21 and the connecting rod 19 return to their original shape under the action of gravity. At the same time, the oil scraper ring 22 slides down under the action of gravity, scraping off the oil on the surface of the rotating sleeve 13, reducing oil adhesion, reducing oil loss, and improving the efficiency of the device.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
