Description

Technical Field

[0001] This utility model relates to the field of oxygen-generating molecular sieve technology, specifically to a convenient disassembly and assembly structure for oxygen-generating molecular sieves. Background Technology

[0002] As the core functional material in pressure swing adsorption (PSA) oxygen generators, the adsorption performance of molecular sieves directly determines the purity of oxygen output and the energy efficiency ratio of the equipment. In practical applications, molecular sieves need to be encapsulated in a dedicated molecular sieve shell and sealed to the equipment's gas path via a cover plate structure. Because molecular sieves have an adsorption saturation cycle and require periodic replacement or regeneration, the ease of assembly and disassembly, sealing reliability, and maintenance efficiency of their encapsulation structure become key factors affecting the continuous operation of the equipment.

[0003] Currently, the commonly used methods for fixing molecular sieves in the industry mainly include two types: bolt fixing: multiple bolt connection points are set between the molecular sieve shell and the equipment frame, and sealing gaskets are used to achieve fastening and airtightness; flange snap-fit: the flanges are connected and locking is achieved by clamps or quick-release clips.

[0004] However, the above solutions have the following technical drawbacks: 1. Bolt fixing requires tightening / unloading one by one. Although flange clips can speed things up slightly, they still require multiple manual alignment and locking operations, which cannot meet the efficiency requirements of high-frequency maintenance scenarios; 2. Both solutions require the use of special tools such as wrenches and calipers, which are extremely inconvenient to operate in emergency maintenance or narrow working spaces. Utility Model Content

The first snap-fit ​​component has arc-shaped strips fixed to the top and bottom of the front side of the molecular sieve shell, and fixing blocks fixed to both sides of the arc-shaped strips. A plug-in block is fixed to the back of the fixing block. The two sides of the front side of the mounting base are provided with mating interfaces for assembling with the plug-in blocks. The locking component includes a fixing base, a connecting strip, a threaded knob, and a locking block. A connecting strip is fixed to the top of the fixing block. A threaded knob is threaded through the connecting strip. The end of the threaded knob is rotatably connected to the connecting strip. Two sets of locking blocks are fixed to the inner side of the connecting strip, and the locking blocks are connected to the positioning base in mutual cooperation.

[0008] Furthermore, the bottom of the cover plate is fixedly connected to an inner sleeve that mates with the molecular sieve shell, and a sealing ring 1 is embedded and installed on the outer side of the inner sleeve. A sealing ring 2 is fitted on the inner sleeve below the cover plate, and a butt joint communicating with the inner sleeve is fixedly installed on the top of the cover plate.

[0009] Furthermore, the plug block has an internal elastically connected snap-fit ​​component 1, which extends out of both sides of the plug block.

[0010] Furthermore, the mounting bases on both sides of the interface are provided with built-in guide grooves, and the second snap-fit ​​component is elastically installed inside the built-in guide grooves, and the second snap-fit ​​component cooperates with the first snap-fit ​​component.

[0014] 1. Simple structure, easy installation, and minimal space occupation, making it particularly suitable for medical oxygen generation, industrial PSA and other scenarios that require frequent replacement of molecular sieves;

[0015] 2. By adopting a composite design of guide plug and elastic buckle, tool-free operation is achieved by "pushing to open and pulling to close"; the assembly and disassembly time is greatly reduced from the operation time of traditional bolt fixing.

This makes disassembly and installation more convenient and quick when changing molecular materials. The sealing ring adopts a double sealing design to ensure that the molecular sieve itself has a good sealing effect. Attached Figure Description

[0035] The docking component 200 includes an arc-shaped strip 201, a fixing block 202, a plug-in block 203, and a snap-fit ​​component 204. The top and bottom of the front of the molecular sieve shell 100 are fixedly connected to the arc-shaped strip 201, and the two sides of the arc-shaped strip 201 are fixedly connected to the fixing block 202. The back of the fixing block 202 is fixedly connected to the plug-in block 203.

[0036] The locking assembly 400 includes a fixed base 401, a connecting bar 402, a threaded knob 403, and a locking block 404. The connecting bar 402 is fixedly connected to the top of the fixed block 202. The threaded knob 403 is threaded through the connecting bar 402. The end of the threaded knob 403 is rotatably connected to the connecting bar 402. Two sets of locking blocks 404 are fixedly connected to the inner side of the connecting bar 402, and the locking blocks 404 are mutually engaged with the positioning base 700.

[0037] Molecular sieve shell 100: A cylindrical structure with an open top, containing molecular sieve material;

[0038] Cover plate 300: Covers the top of molecular sieve shell 100 and is connected to mounting base 500 through docking component 1 200 and docking component 2 600;

[0039] The docking components 1 200 / 2 600 are symmetrically distributed on the bottom and top of the front of the cover plate 300, and are composed of arc strip 201, fixing block 202, plug-in block 203, and snap-fit ​​component 1 204.

[0040] Arc-shaped strip 201: welded to the outer wall of molecular sieve shell 100 to enhance structural strength;

[0041] Fixed block 202: connects the arc-shaped strip 201 and the plug-in block 203;

[0042] Fixing base 401: fixed to the top of fixing block 202;

[0043] Connecting bar 402: extends horizontally above the positioning seat 700, with a threaded knob 403 passing through the middle;

[0044] Locking block 404: The inclined structure matches the positioning groove 701 of the positioning seat 700;

[0045] Installation: Insert the plug block 203 into the interface 502 of the mounting base 500. After the first snap-fit ​​part 204 and the second snap-fit ​​part 505 are engaged, rotate the threaded knob 403. The locking block 404 presses down along the inclined surface of the positioning groove 701 and seals the cover plate 300.

[0046] Disassembly: Rotate the threaded knob 403 in the opposite direction to release the pressure, and gently push the molecular sieve shell 100 to disengage the locking piece 204.

[0047] In this embodiment, the bottom of the cover plate 300 is fixedly connected to an inner sleeve 302 that is connected to the molecular sieve shell 100, and a sealing ring 303 is embedded on the outer side of the inner sleeve 302. A sealing ring 304 is fitted on the inner sleeve 302 below the cover plate 300, and a connector 301 that communicates with the inner sleeve 302 is fixedly installed on the top of the cover plate 300.

[0048] Inner sleeve 302: A cylindrical boss that is inserted into the inner top wall of the molecular sieve shell 100 to form an airflow channel;

[0049] Sealing ring 303: Silicone O-ring, embedded in the outer annular groove of inner sleeve 302 to prevent gas leakage;

[0050] Sealing ring 2 304: Flat EPDM gasket, fitted onto the root of inner sleeve 302 to compensate for axial sealing pressure;

[0051] 301 Connector: Flange interface, for connecting to external gas pipelines.

[0052] In this embodiment, the plug block 203 has a snap-fit ​​member 204 inside, and the snap-fit ​​member 204 extends out of both sides of the plug block 203.

[0053] Snap-fit ​​component 204: Spring steel sheets protruding on both sides, connected to the inner wall of the plug block 203 in the middle by a compression spring;

[0054] Working process: When the connector 502 is inserted, the snap-fit ​​part 204 is squeezed inward; after reaching the built-in guide groove 504, the spring is released, and the protrusion pops out to complete the locking.

[0055] In this embodiment, an internal guide groove 504 is provided in the mounting base 500 on both sides of the interface 502. A second snap-fit ​​component 505 is elastically installed inside the internal guide groove 504, and the second snap-fit ​​component 505 cooperates with the first snap-fit ​​component 204.

[0056] Built-in guide groove 504: rectangular grooves on both sides of interface 502, the depth of which is slightly greater than the thickness of the protrusion of snap-fit ​​part 204;

[0057] Snap-fit ​​part 205: V-shaped spring sheet, fixed to the inner wall of guide groove 504, with inclined surface to guide snap-fit ​​part 204 to disengage;

[0058] Interlocking principle: During disassembly, the molecular sieve shell 100 is pushed past the snap fastener 204 and slides along the V-shaped inclined surface to compress it. When pulled back, it disengages from the snap fastener.

[0059] In this embodiment, the front of the mounting base 500 is provided with an internal groove 501 corresponding to the molecular sieve shell 100, and the four corners of the mounting base 500 are provided with mounting holes 503 for installation.

[0060] Built-in groove 501: U-shaped groove, matching the outer contour of molecular sieve shell 100, restricting lateral displacement;

[0061] Mounting hole 503: Countersunk holes are arranged at the four corners, and the equipment is fixed to the frame with bolts.

[0062] In this embodiment, positioning grooves 701 are provided on both sides of the positioning base 700, and the positioning grooves 701 are configured as inclined surfaces that fit with the locking block 404.

[0063] The positioning groove 701 is a 45° inclined groove with a depth that decreases from the outside to the inside.

[0064] Locking block 404: The bottom is machined to match a 45° bevel.

[0065] Mechanical conversion: When rotating the threaded knob 403, the horizontal screwing force is converted into vertical downward pressure through the inclined plane, pressing the cover plate 300.

[0066] Working principle and usage process of this utility model:

[0067] When in use, first install and fix the mounting base 500 through the mounting hole 503 on its own to make the mounting base 500 fixed inside the filter equipment. Then, connect the cover plate 300 to the molecular sieve shell 100 through the inner sleeve 302. After the connection is completed.

[0068] During installation, the molecular sieve shell 100 is assembled with the mounting base 500 by connecting the fixing blocks 202 on both sides. The fixing blocks 202 are connected with the interface 502 by the plug-in block 203 on the back. When it enters, the snap-fit ​​part 204 is compressed into the plug-in block 203. When it reaches the position of the built-in guide groove 504, it actively protrudes and snaps into the built-in guide groove 504.

[0069] During disassembly, personnel only need to push the molecular sieve shell 100 again to cause the first snap fastener 204 to move inward again and pass over the second snap fastener 505, and then pull it back. The structure of the second snap fastener 505 guides the first snap fastener 204 to release the restriction of the built-in guide groove 504. It is worth noting that both the first snap fastener 204 and the second snap fastener 505 are equipped with springs on their inner sides to provide structural elasticity.

[0070] After the molecular sieve shell 100 is installed, the operator can rotate the threaded knobs 403 on both sides to rotate the connecting strip 402 closer to the connecting strip, causing the inner locking block 404 to continuously push into the positioning groove 701. Since the bottom of the locking block 404 and the positioning groove 701 are mutually fitted inclined structures, when the locking block 404 is continuously pushed in, the positioning seat 700 will be subjected to compressive force and downward pressure. The purpose of this is to cooperate with the cover plate 300 to seal the port of the molecular sieve shell 100 and ensure the sealing effect between the cover plate 300 and the molecular sieve shell 100.

[0071] To disassemble, simply rotate the threaded knob 403 in the opposite direction.
