Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separation, in particular to an air purification device used for oil-gas separation in a ship engine room. Background Art

[0002] There are a large number of mechanical equipment in the ship's engine room, such as the main engine system, steam turbine, water pump and other equipment, which need to be lubricated, cooled and regulated by engine oil. Under high temperature and high-speed rotation conditions, engine oil will release a large amount of oil and gas, which will continue to accumulate in the narrow engine room of the ship, seriously affecting the safe operation of various equipment in the engine room and the health of the crew. Therefore, a corresponding oil and gas separation and purification device is needed to effectively purify the oil and gas in the cabin air. Existing oil and gas separation and purification devices usually use the principle of filtration and adsorption to separate oil and gas. Not only does it require regular replacement of the filter element, but in order to avoid polluting the environment, the used filter element also needs to be treated twice, resulting in a relatively high maintenance cost for using the filter element to filter oil and gas.

[0003] A centrifugal oil-gas separation device is disclosed in a Chinese patent document with the announcement number CN209060712U, including a separator, the bottom of which is fixed in the cabin through a rubber shock absorber, the upper part of which is equipped with a hollow fixing seat, and a motor is installed above the fixing seat, and the transmission shaft of the motor extends into the fixing seat, the separator includes a shell, a main shaft and a plurality of separation plates, the plurality of separation plates are mounted on the main shaft through mounting holes, the air guide holes of the upper and lower separation plates overlap each other to form an air intake channel, so that the mixed gas below enters the gap between each separation plate through the air guide hole, and the air guide slots of the plurality of separation plates together with the main shaft wall form an air guide groove. By utilizing the different specific gravities of oil and air, the main shaft is driven to rotate by a high-speed motor to form a centrifugal force, so that the heavier oil is located at the periphery and thrown on the separation plate, while the lighter air is located in the middle area and discharged upward through the air guide groove.

[0004] The disadvantage of the above-mentioned disclosed solution is that when heavier oil is thrown onto the separation plate, although the oil accumulated on the separation plate is thrown onto the side wall of the shell under the action of centrifugal force, the speed at which the oil separates from the separation plate is relatively slow under the action of centrifugal force alone, which makes it inconvenient to discharge the oil quickly.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: an air purification device for oil and gas separation in a ship engine room, comprising a separator 1, on the top surface of which is mounted an exhaust pipe 3 connected to the inside of the separator 1, so as to facilitate the discharge of separated air.

[0023] A motor 2 is fixedly installed at the center of the top upper surface of the separator 1. The output end of the motor 2 passes through the separator 1 and is fixedly installed with a rotating shaft 11. The bottom of the rotating shaft 11 is rotatably mounted with the center of the bottom wall in the separator 1. A sleeve 14 is slidably sleeved on the outer surface of the rotating shaft 11 along its length extension direction. A limiting structure is installed between the rotating shaft 11 and the sleeve 14, and the limiting structure is used to limit the relative rotation of the rotating shaft 11 and the sleeve 14.

[0024] The limiting structure includes a limiting groove 13 and a limiting strip. The limiting groove 13 is located on the outer surface of the rotating shaft 11, and the limiting groove 13 is opened along the length extension direction of the rotating shaft 11. The limiting strip is located inside the sleeve 14, and is fixedly installed with the sleeve 14. The limiting strip is adapted to the limiting groove 13, and the limiting strip is installed in a sliding manner with the limiting groove 13. This facilitates the sleeve 14 to slide up and down along the rotating shaft 11 without rotating relative to the rotating shaft 11.

[0025] Specifically, three limiting grooves 13 are arranged in a circumferential array along the outer circumference of the rotating shaft 11, and three limiting strips are arranged in a circumferential array along the inner circumference of the sleeve 14. The limiting strips correspond to the limiting grooves 13 one by one and are installed in a sliding manner to increase the stability of the sleeve 14 when it moves up and down along the rotating shaft 11.

[0026] The outer surface of the sleeve 14 is provided with a fixed ring 15 at even intervals along its length direction, and a separator 7 is fixedly mounted on the fixed ring 15. A mounting hole is provided in the center of the separator 7, and the inner side of the mounting hole is fixedly mounted with the outer side of the fixed ring 15. Air guide holes 8 are provided in the separator 7 along its circumferential array, and the air guide holes 8 of adjacent separators 7 are aligned with each other to form an air inlet channel. It is convenient for the mixed gas below to enter the space formed by each separator 7 through the air guide holes 8, thereby improving the separation processing efficiency.

[0027] The center of the separation sheet 7 bulges upward, and the periphery of the separation sheet 7 gradually tilts downward away from the center, so that the mixed gas moves upward along the air inlet channel formed by the air guide hole 8, preventing gas backflow, increasing the collection area, and facilitating the separated oil to flow to the edge of the separation sheet 7.

[0028] A slide bar 10 is symmetrically fixedly installed at the bottom of the separator 7 near the inner bottom wall of the separator 1. The slide bar 10 is arranged vertically downward, and a hemispherical body 16 is fixedly installed at one end of the slide bar 10 away from the separator 7. A circular track 18 is opened at the bottom of the separator 1 with the rotating shaft 11 as the center, and the bottom of the slide bar 10 is installed in a sliding fit with the track 18. A protrusion 17 is fixedly installed in the track 18. The protrusion 17 is a trapezoidal structure. The hemispherical body 16 is slidably abutted with the track 18, and the spherical surface of the hemispherical body 16 and the inclined surface of the protrusion 17 are slidably matched to make the separator 7 move up and down. It is convenient to vibrate the separator 7 so that the oil can be quickly separated from the separator 7.

[0029] The bottom wall of the separator 1 is provided with an annular oil collecting groove 12 with the rotating shaft 11 as the center, and the annular oil collecting groove 12 cooperates with the inner wall of the separator 1 to form an oil collecting area. The bottom of the separator 1 is provided with an oil discharge port 5, which is connected to the oil collecting groove 12. It is convenient to discharge the oil in the oil collecting groove 12. The diameter of the separation sheet 7 is larger than the diameter of the inner ring of the oil collecting groove 12, ensuring that the oil can fall into the oil collecting groove 12.

[0030] An air intake pipe 4 is fixedly installed at the center of the bottom lower surface of the separator 1, and a plurality of air intake holes 9 are opened on the bottom wall inside the separator 1. The plurality of air intake holes 9 are connected to the interior of the separator 1 and the air intake pipe 4, so that the mixed gas can enter the interior of the separator 1 through the air intake pipe 4 and the air intake holes 9.

[0031] The top and bottom of the rotating shaft 11 are both fixedly installed with connecting plates 19 in a horizontal direction. The two connecting plates 19 are parallel to each other. A scraper 6 is fixedly installed between the ends of the two connecting plates 19 on the same side. The scraper 6 is arranged and installed vertically, and the scraper 6 fits the inner wall of the separator 1. When the scraper 6 rotates, the oil thrown by the separation sheet 7 onto the inner wall of the separator 1 is gathered together, so that the oil can quickly flow to the oil collecting tank 12 below. At the same time, it prevents the oil from remaining on the inner wall of the separator 1.

[0032] The working principle of an air purification device for oil and gas separation in a ship engine room provided by the utility model is as follows:

[0033] When in use, the air inlet pipe 4 is connected to an external air extraction device, and the external mixed gas is sucked into the interior of the separator 4 through the air inlet pipe 4 and the air inlet hole 9.

[0034] Then, start the motor 2, which drives the rotating shaft 11 to rotate, the rotating shaft 11 drives the sleeve 14 to rotate, the sleeve 14 drives the fixing ring 15 to rotate, the fixing ring 15 drives the separation plate 7 to rotate, and the rotation of the separation plate 7 causes the mixed gas inside the separator 1 to form a vortex and enter the space formed by each separation plate 7 from the air guide hole 8.

[0035] Then, by utilizing the different specific gravities of oil and air, the separation sheet 7 generates centrifugal force during rotation, separating the heavier oil from the lighter air. The heavier oil is then thrown onto the separation sheet 7, while the lighter air is discharged upward through the exhaust pipe 3 via the air guide holes 8.

[0036] The oil on the separator 7 is thrown onto the inner wall of the separator 1 under the action of centrifugal force. When the separator 7 rotates, the separator 7 drives the slide bar 10 to rotate, and the slide bar 10 drives the hemisphere 16 to rotate along the track 18. When the hemisphere 16 contacts the protrusion 17 and slides along the upper surface of the protrusion 17, the hemisphere 16 moves upward to drive the slide bar 10 to move upward, and the slide bar 10 moves upward to drive the separator 7 to move upward, and the separator 7 drives the fixing ring 15 and the sleeve 14 to move upward. When the hemisphere 16 is separated from the upper surface of the protrusion 17, the separator 7 drives the fixing ring 15, the sleeve 14, the slide bar 10 and the hemisphere 16 to move downward at the same time under the action of its own gravity, so that the hemisphere 16 continues to rotate along the track 18. Therefore, during the rotation process, the separator 7 can also move up and down at the same time, so that the separator 7 vibrates and accelerates the separation of the oil from the separator 7.

[0037] The rotation of the rotating shaft 11 also drives the connecting plate 19 to rotate, and the rotation of the connecting plate 19 drives the scraper 6 to rotate. Under the action of the scraper 6, the oil on the inner wall of the separator 1 is scraped off to prevent the oil from remaining on the inner wall of the separator 1. The oil on the inner wall of the separator 1 is quickly gathered and flows along the scraper 6 to the oil collecting tank 12 at the bottom of the separator 1, so that the oil is quickly discharged from the oil outlet 5.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
