Description

Technical Field

[0001] This utility model relates to the technical field of oxygen separation equipment, specifically to an air inlet sealing device for an oxygen separation equipment. Background Technology

[0002] Oxygen is an elemental form of oxygen, with the chemical formula O2. It is chemically reactive, reacting with many elements in oxidation reactions. At room temperature, it is not very reactive and does not readily react with many substances. Oxygen is the most abundant element in nature, making up 48.6% of the Earth's crust. It is essential for various applications, including hydrocarbon oxidation, wastewater treatment, rocket propellant, and providing respiration for animals and humans in aviation, aerospace, and diving.

[0003] The air inlet of an oxygen separator is the inlet part that connects the equipment to external air or raw material gas. It is usually a pipe interface or opening with a certain diameter, and its location is generally at the front end of the equipment. It is used to introduce the air or other mixed gas to be separated.

[0004] During the installation of sealing valves, manual rotation of handwheels or wrenches is required, which is time-consuming and labor-intensive. Some air inlet valves are located in areas with dense pipelines, requiring maintenance personnel to climb or disassemble components to operate them. Therefore, it is necessary to provide an air inlet sealing device that can be installed quickly, reducing installation difficulty and improving installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing device for the air inlet of an oxygen separation device, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a sealing device for the air inlet of an oxygen separation equipment, comprising:

[0007] The enclosure, air inlet, and sealing valve are provided, with the air inlet connected to one side of the enclosure and the sealing valve installed on one side of the air inlet.

[0008] The mounting assembly includes a flange, circular holes, fixed frames, movable holes, and movable columns. The flange is fixed to one side of the air inlet. Five circular holes are equally spaced on the outer surface of the flange. Five fixed frames are fixed on the outer surface of the corresponding circular holes. Movable holes are on the outer surface of the fixed frames and are directly opposite to the circular holes. The movable columns slide through the interior of the movable holes.

[0009] Furthermore, an air outlet is fixed on the upper surface of the housing, and the end of the movable column extends into the circular hole, with an inclined groove provided at the end of the movable column.

[0010] Furthermore, two baffles are fixed to the outer surface of the movable column. One baffle is fixed to the middle of the movable column, and the other baffle is fixed to the end of the movable column. The middle baffle is located inside the fixed frame.

[0011] Furthermore, a first spring is fixed to one side of the baffle in the middle, and the first spring is located inside the fixed frame, and a locking pin is fixed to one side of the sealing valve.

[0012] Furthermore, a slot is formed on the outer surface of the locking post, the slot corresponds to the circular hole, and the end of the movable post extends into the slot.

[0013] Furthermore, it also includes a sealing assembly, which includes a rotating column, a sealing disc, and a mounting groove. The rotating column rotates through the inside of the sealing valve, the sealing disc rotates through the inside of the rotating column, and the sealing disc is rotated and placed inside the air inlet. The mounting groove is opened on both sides inside the sealing disc.

[0014] Furthermore, a second spring is fixed inside the mounting groove, and a sealing plate is fixed to the end of the second spring, with the sealing plate in contact with the inner wall of the air inlet. A rotating wheel is fixed to the upper surface of the rotating column.

[0015] This utility model has the following beneficial effects:

[0016] This utility model relates to a housing, air inlet, air outlet, sealing valve, and installation components. When installing the sealing valve, one side of the sealing valve is first installed on the side of the air inlet. Guided by the inclined groove at the end of the movable column, the movable column is pushed outward, causing the baffle to move outward. Under the limitation of the fixed frame, the baffle compresses the first spring, and the locking pin on one side of the sealing valve will lock into the flange. When the locking groove aligns with the circular hole, the first spring quickly recovers its deformation under the elastic force of the spring, driving the movable column into the locking groove. The sealing valve is then installed on one side of the air inlet. The other side of the sealing valve is installed by repeating the above steps. The initial alignment of the sealing valve and the air inlet can be achieved with just a simple pushing action, significantly reducing installation difficulty, shortening installation time, and improving installation efficiency.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is an air inlet sealing device for an oxygen separation equipment, comprising:

[0029] The enclosure 11, the air inlet 12 and the sealing valve 14 are connected to one side of the enclosure 11 and the sealing valve 14 is installed on one side of the air inlet 12.

[0030] The mounting components include a flange 21, circular holes 22, a fixing frame 23, movable holes 24, and movable columns 25. The flange 21 is fixed to one side of the air inlet 12. Five circular holes 22 are provided, which are equally spaced on the outer surface of the flange 21. Five fixing frames 23 are fixed on the outer surface of the corresponding circular holes 22. The movable holes 24 are provided on the outer surface of the fixing frames 23, and the movable holes 24 are directly opposite to the circular holes 22. The movable column 25 slides through the interior of the movable holes 24.

[0031] The housing 11 is the same model as that in a high-efficiency oxygen separation device with patent number CN220696176U. The housing 11 is one of the main structures of the oxygen separation device, used to accommodate various internal components and working media, and to provide a stable space environment for the normal operation of the device. The air inlet 12 is the entrance for external air or the mixed gas to be separated into the oxygen separation device. Its main function is to accurately deliver the raw material gas into the device. The sealing valve 14 is installed on one side of the air inlet 12. Its main function is to ensure the sealing of the air inlet 12 and prevent gas leakage.

[0032] An air outlet 13 is fixed on the upper surface of the housing 11. The end of the movable column 25 extends into the circular hole 22. An inclined groove is opened at the end of the movable column 25. Two baffles 26 are fixed on the outer surface of the movable column 25. One baffle 26 is fixed in the middle of the movable column 25, and the other baffle 26 is fixed at the end of the movable column 25. The middle baffle 26 is located inside the fixed frame 23.

[0033] Flange 21 is an important component connecting the air inlet 12 and the sealing valve 14. The main function of the circular hole 22 is to provide guidance and positioning for the movement of the movable column 25. The fixed frame 23 limits the movement of the movable column 25. The movable hole 24 is a channel through which the movable column 25 slides, allowing the movable column 25 to slide under the restriction of the fixed frame 23. When the sealing valve 14 approaches the air inlet 12, the inclined groove at the end of the movable column 25 interacts with the locking column 28, pushing the movable column 25 to move outward. The movement of the movable column 25 will drive the baffle 26 and the first spring 27 to move, thereby realizing the automatic locking and positioning of the sealing valve 14.

[0034] A first spring 27 is fixed on one side of the middle baffle 26, and the first spring 27 is located inside the fixed frame 23. A locking post 28 is fixed on one side of the sealing valve 14. A locking groove 29 is opened on the outer surface of the locking post 28. The locking groove 29 corresponds to the circular hole 22, and the end of the movable post 25 extends into the locking groove 29.

[0035] The baffle 26 in the middle is mainly used to interact with the components in the fixed frame 23 during the movement of the movable column 25, compressing the first spring 27. The baffle 26 at the end plays a limiting role when the movable column 25 moves to the limit position, preventing the movable column 25 from moving excessively. The model of the first spring 27 is selected according to the actual use requirements, as long as it meets the working needs.

[0036] Working principle:

[0037] Confirm that the sealing valve 14, air inlet 12, and related components are free of impurities and oil stains. Ensure that the flange 21, slot 29, circular hole 22, and other structures are free from deformation and damage. Move the sealing valve 14 to the vicinity of the air inlet 12, maintaining the correct installation orientation, aligning the retaining post 28 of the sealing valve 14 with the slot 29 of the flange 21 of the air inlet 12. Align one side of the sealing valve 14 with one side of the air inlet 12, and slowly push the sealing valve 14 closer to the air inlet 12. During this approach, the end of the sealing valve 14 contacts the inclined groove at the end of the movable post 25. Guided by the inclined groove, the movable post 25 is pushed outward, and the movable post 25 drives the baffle 26 to move outward simultaneously. When the baffle 26 is in motion, under the limiting constraint of the fixed frame 23, it compresses the first spring 27, causing the first spring 27 to store elastic potential energy and continuously push the sealing valve 14 until the locking post 28 on one side of the sealing valve 14 is completely locked into the flange 21. At this time, carefully observe the positional relationship between the slot 29 and the circular hole 22. When the two are positively aligned, the first spring 27 quickly releases its elastic potential energy, restores its deformation, and drives the movable post 25 to quickly lock into the slot 29, completing the installation and fixing of one side of the sealing valve 14. Repeat the steps of single-side installation, align the other side of the sealing valve 14 with the other side of the air inlet 12, and complete the installation of the other side of the sealing valve 14 according to the process.

[0038] This step allows for the initial alignment of the sealing valve 14 and the air inlet 12 with a simple pushing action, significantly reducing installation difficulty, shortening installation time, and improving installation efficiency.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The sealing assembly includes a rotating column 31, a sealing disc 32, and a mounting groove 33. The rotating column 31 rotates through the inside of the sealing valve 14, the sealing disc 32 passes through the inside of the rotating column 31, and the sealing disc 32 is rotated and placed inside the air inlet 12. The mounting groove 33 is opened on both sides inside the sealing disc 32.

[0041] When the operator rotates the rotating wheel 36, the rotating wheel 36 transmits torque to the rotating column 31, and the rotating column 31 then transmits this rotational motion to the sealing disc 32, thereby starting the entire sealing process. The sealing disc 32 adjusts its position and achieves sealing through its own rotational motion. The main function of the mounting groove 33 is to accommodate the second spring 34 and the sealing rubber plate 35 and to provide them with accurate positioning.

[0042] A second spring 34 is fixed inside the mounting groove 33. A sealing plate 35 is fixed to the end of the second spring 34, and the sealing plate 35 contacts the inner wall of the air inlet 12. A rotating wheel 36 is fixed to the upper surface of the rotating column 31.

[0043] The two sides of the sealing plate 35 are in close contact with the inner wall of the mounting groove 33. The main function of the second spring 34 is to provide elastic force so that the sealing plate 35 can be in close contact with the inner wall of the air inlet 12 and generate sufficient pressure, thereby achieving a reliable seal. The sealing plate 35 is made of rubber material with good elasticity, wear resistance and sealing performance. Under the action of the second spring 34, the sealing plate 35 can fit tightly against the inner wall of the air inlet 12, fill the small irregularities on the surface of the air inlet 12, form a reliable sealing barrier and effectively prevent gas from leaking from the air inlet.

[0044] Working principle:

[0045] When sealing the air inlet 12, simply rotate the rotating wheel 36. The rotating wheel 36 drives the rotating column 31 to rotate, and the rotating column 31 drives the sealing disc 32 to rotate inside the air inlet 12. The rotation of the sealing disc 32 will compress the second spring 34 into the mounting groove 33. The compression of the second spring 34 will simultaneously drive the sealing rubber plate 35 to retract into the mounting groove 33. Under the elastic force of the second spring 34, the sealing rubber plate 35 will be in close contact with the inner wall of the air inlet 12, thus sealing the air inlet 12.

[0046] In this step, the second spring 34 pushes the sealing plate 35 to fit tightly against the inner wall of the air inlet 12, which can automatically compensate for dimensional deviations caused by pipeline processing errors, thermal expansion and contraction, etc., to ensure high airtightness and reduce the risk of gas leakage.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
