Description

Technical Field

[0001] This utility model belongs to the field of oil and gas tank technology, and in particular relates to an oil and gas tank with high efficiency oil and gas separation. Background Technology

[0002] The oil separator is a common name for a key component in compressors (especially screw air compressors); its more professional name is oil separator or simply oil separator. The core function of the oil separator is to effectively separate the highly mixed compressed air and lubricating oil (cooling oil) generated by the compressor.

[0003] There are many types of oil-gas separators on the market. For example, a new type of oil-gas separator with the publication number CN211384365U is disclosed on the China Patent Network. This type of oil-gas separator has a simple structure, is easy to operate, is convenient to use, and has obvious effects. By using this cyclone isolation tank and separation method, the oil and gas can be completely separated, which can improve the quality of the discharged gas, reduce the amount of oil consumed, effectively prevent damage to the compressor components, and improve the service life of the compressor. However, there are some defects and shortcomings that need to be improved: (1) Due to the structural design of some existing oil-gas separators, when a high-speed oil-gas mixture enters the oil-gas separator, it is easy to generate turbulence in the tank, thereby interfering with the sedimentation of oil droplets. This will not only reduce the efficiency of oil-gas separation, but also increase the burden on the filter element; (2) Most of the existing oil-gas separators adopt an integrated structure design, which is not easy to disassemble. When the filter element in the oil-gas separator is blocked by oil stains due to long-term use, the tank cover of the oil-gas separator needs to be opened to take out the filter element from the tank and replace it. The whole process is cumbersome and inconvenient. Therefore, the oil-gas separator provided by this utility model is of great significance in addressing the above problems. Utility Model Content

[0004] This invention provides an efficient oil-gas separator tank. A cyclone separator forces the oil-gas mixture entering the tank to change from linear motion to spiral flow, reducing the inlet velocity and thus minimizing direct impact on the tank wall. Multiple guide vanes and guide holes on each vane divide the large flow into multiple smaller streams, disrupting the large-scale vortex structure and effectively preventing turbulence within the tank that could interfere with oil droplet settling. This not only improves oil-gas separation efficiency but also reduces the burden on the filter element. The top plate can be rotated in the opposite direction to remove the filter element from the tank. The filter element can then be quickly replaced by pulling it out of the mounting cylinder. The entire process of removing and replacing the filter element does not require opening the tank lid, making it more convenient and faster. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model discloses a high-efficiency oil-gas separator, comprising a barrel body, with several support legs fixedly connected to the bottom of the barrel body. An air inlet pipe and an oil return pipe are respectively provided on the side wall and bottom of the barrel body. A one-way valve is installed inside the oil return pipe. A cyclone separator is installed at the inner end of the air inlet pipe. A barrel cover is installed on the top of the barrel body. A flow guide and a fixing cylinder are fixedly connected to the bottom of the barrel cover. The fixing cylinder is circular and located inside the flow guide, with its top end connected to the barrel cover. A top plate is installed on the top of the barrel cover, with an air outlet pipe on its top. A pair of handles are fixedly connected to the top of the top plate, symmetrically distributed on both sides of the air outlet pipe. An installation cylinder, which is circular, is fixedly connected to the bottom of the top plate and contains a filter element.

[0006] Furthermore, the cyclone separator is circular, with its diameter being equal to the inner diameter of the air inlet pipe, and several blades with an inclination angle of 45° to 60° are distributed in a ring on the cyclone separator.

[0007] Furthermore, the barrel body is circular, with a protrusion at its top edge and several positioning holes. The positioning holes are equidistantly distributed in a circle along the circumference of the barrel body. The barrel lid is circular, with a diameter equal to that of the barrel body. Several positioning rods are fixedly connected to the bottom of the barrel lid. The number of positioning rods is the same as that of the positioning holes, and their diameters are equal to those of the positioning holes. The center of each positioning rod corresponds one-to-one with the center of each positioning hole. Each positioning rod has an external thread and is threadedly connected to a nut that mates with it.

[0008] Furthermore, the flow guide is cylindrical, and several flow guide plates are fixedly connected to its outer wall. The flow guide plates are elongated and are distributed in an equidistant circular pattern along the circumference of the flow guide. Each flow guide plate has several flow guide holes, which are distributed linearly at equal intervals along the length of the flow guide plate.

[0009] Furthermore, the outer diameter of the mounting cylinder is equal to the inner diameter of the fixing cylinder, and the outer wall of the mounting cylinder and the inner wall of the fixing cylinder are respectively provided with mutually mating external threads and internal threads.

[0010] Furthermore, the filter element is circular, and its diameter is equal to the inner diameter of the mounting cylinder.

[0011] The present invention has the following advantages over the prior art: (1) When using the oil-gas tank for high-efficiency oil-gas separation in this utility model, the oil-gas mixture fluid entering the tank can be forced to change from linear motion to spiral forward by the hydrocyclone, so as to reduce the inlet flow velocity and reduce the direct impact of the oil-gas mixture on the tank wall. Through multiple guide plates and multiple guide holes on each guide plate, the large flow of fluid can be divided into multiple fine streams to destroy the large-scale vortex structure, thereby effectively preventing the oil-gas mixture from generating turbulence in the tank after entering the tank and interfering with the oil droplet settling. This not only improves the efficiency of oil-gas separation, but also effectively reduces the burden on the filter element. (2) When using the oil-gas separator of the present invention, the filter element can be removed from the tank along with the filter element by rotating the top plate in the opposite direction. Then the filter element can be quickly replaced by pulling it out of the installation cylinder. The entire process of removing and replacing the filter element does not require opening the tank cover, which is more convenient and faster.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Please see Figure 1-6 As shown, this utility model discloses a high-efficiency oil-gas separator, comprising a barrel body 1. Several support legs 2 are fixedly connected to the bottom of the barrel body 1. An air inlet pipe 3 and an oil return pipe 4 are respectively provided on the side wall and bottom of the barrel body 1. A one-way valve 5 is installed inside the oil return pipe 4. An oil-gas mixture can be introduced into the barrel body 1 through the air inlet pipe 3. After oil-gas separation, the separated lubricating oil collects at the bottom of the barrel body 1 and can be returned to the compressor host for recycling through the oil return pipe 4. The one-way valve 5 controls the oil return speed to prevent gas backflow or excessive oil absorption, which would reduce the separation effect. A cyclone separator 6 is installed at the inner end of the air inlet pipe 3. A barrel cover 7 is installed on the top of the barrel body 1. A guide shroud 8 and a fixed... The fixed cylinder 9 is circular and located inside the guide shroud 8. The top of the fixed cylinder 9 is connected to the barrel cover 7. A top plate 10 is installed on the top of the barrel cover 7. An air outlet pipe 11 is opened on the top of the top plate 10. A pair of handles 12 are fixedly connected to the top of the top plate 10. The handles 12 are symmetrically distributed on both sides of the air outlet pipe 11. An installation cylinder 13 is fixedly connected to the bottom of the top plate 10. The installation cylinder 13 is circular and has a filter element 14 inside. The filter element 14 is made of multiple layers of fine fiber material (such as glass fiber). It can efficiently capture tiny oil mist and oil droplets suspended in the compressed air, causing them to condense into oil droplets and fall down. The separated clean compressed air can be discharged from the air outlet pipe 11 so that it can enter the downstream cooler or be directly used by the user.

[0019] The hydrocyclone 6 is circular, and its diameter corresponds to the inner diameter of the air inlet pipe 3. Several blades with an inclination angle of 45° to 60° are distributed in a ring on the hydrocyclone 6. When the high-speed oil-gas mixture enters the barrel 1 through the air inlet pipe 3, it will first flow through the hydrocyclone 6. The blades on the hydrocyclone 6 can force the oil-gas mixture to change from linear motion to spiral forward, so as to reduce the inlet flow velocity and thus reduce the direct impact of the oil-gas mixture on the barrel wall.

[0020] The barrel body 1 is circular, with several positioning holes 15 protruding outward from its top edge. These positioning holes 15 are equidistantly distributed in a circle along the circumference of the barrel body 1. The barrel lid 7 is circular, with a diameter equal to that of the barrel body 1. Several positioning rods 16 are fixedly connected to the bottom of the lid 7. The number of positioning rods 16 is the same as the number of positioning holes 15, and their diameters correspond to the diameters of the positioning holes 15. The center of each positioning rod 16 corresponds one-to-one with the center of each positioning hole 15. Each positioning rod 16 has an outer... The cylinder is threaded and connected to a nut 17 that mates with it. When the cylinder cover 7 is placed on top of the cylinder body 1, each positioning rod 16 can be aligned and pass through the corresponding positioning hole 15. At this time, the nut 17 is threaded onto each positioning rod 16. The cylinder cover 7 can be firmly fixed to the top of the cylinder body 1 through the mutual cooperation between the positioning rod 16, the positioning hole 15, and the nut 17 to prevent the cylinder cover 7 from loosening. When the oil and gas cylinder is used for a long time, the cylinder cover 7 can be removed from the top of the cylinder body 1 by unscrewing the nut 17 so that the inside of the cylinder body 1 can be cleaned regularly.

[0021] The flow guide shroud 8 is cylindrical, with several flow guide plates 18 fixedly connected to its outer wall. The flow guide plates 18 are elongated and are distributed in an equidistant circular pattern along the circumference of the flow guide shroud 8. Each flow guide plate 18 has several flow guide holes 19, which are distributed linearly at equal intervals along the length of the flow guide plate 18. After the oil-gas mixture enters the barrel 1 through the air inlet pipe 3, the flow guide shroud 8 can guide the airflow to radiate and diffuse evenly to the inner wall of the barrel 1. At the same time, the multiple flow guide plates 18 and the multiple flow guide holes 19 on each flow guide plate 18 can divide the large flow of fluid into multiple fine streams to destroy the large-scale vortex structure. This can effectively prevent the oil-gas mixture from generating turbulence in the barrel after entering the barrel 1 and interfering with the oil droplet settling. This not only improves the efficiency of oil-gas separation but also effectively reduces the burden on the filter element 14.

[0022] The outer diameter of the mounting cylinder 13 is equal to the inner diameter of the fixing cylinder 9. The outer wall of the mounting cylinder 13 and the inner wall of the fixing cylinder 9 are respectively provided with mutually mating external threads and internal threads. By holding the handle 12, the top plate 10 can be rotated. When the top plate 10 rotates, the top plate 10 together with the filter element 14 can be fixed in the barrel 1 through the threaded engagement between the mounting cylinder 13 and the fixing cylinder 9. When the filter element 14 is clogged with oil due to long-term use, it can be removed from the barrel 1 together with the filter element 14 by rotating the top plate 10 in the opposite direction without opening the barrel cover 7.

[0023] The filter element 14 is circular, and its diameter is equal to the inner diameter of the mounting cylinder 13. The top of the filter element 14 can be inserted into and attached to the inner wall of the mounting cylinder 13 so that the filter element 14 can be fixed by insertion. After the top plate 10 is removed from the barrel 1, the filter element 14 can be pulled out from the mounting cylinder 13 so that the filter element 14 can be quickly replaced.

[0024] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0025] The working principle of this utility model is as follows: In use, this invention allows an oil-gas mixture to be introduced into the container 1 via the air inlet pipe 3. Upon entering the container 1, the high-speed oil-gas mixture first flows through the cyclone separator 6. The blades on the cyclone separator 6 force the oil-gas mixture to change from linear motion to spiral motion, reducing the inlet velocity and thus minimizing the direct impact of the oil-gas mixture on the container wall. After entering the container 1 through the air inlet pipe 3, the airflow is guided by the flow guide shroud 8 to diffuse evenly towards the inner wall of the container 1. Simultaneously, multiple flow guide vanes 18 and their corresponding flow guide holes 19 divide the large flow into multiple smaller streams, disrupting the large-scale vortex structure. This effectively prevents turbulence from forming inside the container after the oil-gas mixture enters the container 1, thus preventing interference with oil droplet settling and improving efficiency. This improves the efficiency of oil-gas separation and effectively reduces the burden on filter element 14. The high-speed rotating oil-gas mixture then generates a strong centrifugal force field within the tank 1. This causes heavier oil droplets to be thrown towards the inner wall of the oil-gas tank under centrifugal force, while lighter gas tends to flow towards the center. The vast majority (approximately 95%) of the large oil droplets lose kinetic energy under the influence of centrifugal force and impact with the tank wall, coalescing and flowing down the tank wall until they converge at the bottom of the tank 1. The gas after initial separation (still containing a large amount of tiny oil mist and aerosol-like oil droplets) flows upwards to the next stage of separation. When the gas containing tiny oil mist (particle size typically 0.1~5μm) flows through the fiber layer of filter element 14, the tiny oil droplets are affected by inertial collisions, direct interception, or Brownian motion (random thermal motion). The oil droplets come into contact with the fibers and are adsorbed onto the fiber surface. The small oil droplets adsorbed on the fibers then coalesce (agglomerate) into larger droplets. As more oil droplets are adsorbed and coalesce, the droplet size continues to increase. When the coalesced droplets are large enough (their weight generates enough gravity to overcome the upward drag force of the gas and the adhesion force on the fiber surface), the oil droplets will drip off the fibers. After passing through filter element 14, the residual tiny oil mist in the compressed air is efficiently removed, resulting in clean compressed air (oil content as low as 3 ppm). Even below) it is discharged from the outlet pipe 11, while the separated oil droplets fall into the bottom of the barrel 1, thus realizing oil-gas separation. Then, the lubricating oil accumulated at the bottom of the barrel 1 can be returned to the compressor host for recycling through the oil return pipe 4. When the filter element 14 is clogged with oil due to long-term use, it can be removed from the barrel 1 together with the filter element 14 by rotating the top plate 10 in the opposite direction. Then, the filter element 14 can be quickly replaced by pulling it out of the installation cylinder 13. The entire process of removing and replacing the filter element 14 does not require opening the barrel cover 7, which is more convenient and faster.
