Description

Technical Field

[0002] In the field of nitrogen generators, a two-stage separation adsorption tower is the core equipment for achieving air separation and producing high-purity nitrogen. In the prior art, publication number CN219489607U discloses a two-stage separation adsorption tower for a nitrogen generator, which achieves staged adsorption of oxygen in the air through a series design of a primary adsorption component and a secondary adsorption component, thereby improving the purity of nitrogen. However, this technical solution has the following shortcomings in practical applications:

[0003] The adsorption components are difficult to disassemble and assemble: the primary and secondary adsorption components are usually fixed and tightly connected to the tower body. This means that when replacing the molecular sieve or performing maintenance, a large number of fasteners need to be disassembled, which is cumbersome and time-consuming.

[0004] Low maintenance efficiency: Due to the inconvenience of disassembly and assembly, the downtime for equipment maintenance is extended, affecting the continuity of production. In particular, in scenarios where molecular sieves need to be replaced frequently, maintenance costs increase significantly. Utility Model Content

[0032] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] Please refer to Figures 1 to 6 As shown, an embodiment of this utility model provides a two-stage separation adsorption tower for a nitrogen generator, comprising: a tower body 1 and a partition 2 fixedly connected to the inner wall of the tower body 1. A detachable adsorption component 3 is provided inside the tower body 1 and on one side of the partition 2, and a detachable adsorption component 4 is provided inside the tower body 1 and on the other side of the partition 2. The adsorption component 3 is fixedly connected to the tower body 1 through an inlet end cap 6, and the adsorption component 4 is fixedly connected to the tower body 1 through an outlet end cap 5.

[0034] By adopting the above technical solution, adsorption component 3 and adsorption component 4 are movably installed inside the tower body 1 through the outlet end cover 5 and the inlet end cover 6, respectively. When disassembling, it is only necessary to pull the operating block 505 to make the sliding rod 5041 disengage from the slot 5031, and the adsorption component can be quickly removed without the need for wrenches or other tools. One person can complete the disassembly and assembly, reducing labor intensity, and is especially suitable for high-frequency maintenance scenarios.

[0035] In order to achieve gas flow and interface standardization, in this embodiment: an air inlet 61 is installed on the air inlet end cover 6, and an air outlet 51 is installed on the air outlet end cover 5.

[0036] In order to achieve rapid and accurate positioning of the adsorption component, in this embodiment: symmetrically arranged positioning blocks 501 are fixedly connected to the gas outlet end cap 5, and a positioning groove 5011 matching the positioning block 501 is opened on the tower body 1 at the position corresponding to the positioning block 501. The symmetrically distributed positioning blocks 501 and the positioning groove 5011 form a unique assembly direction to avoid sealing failure or structural interference caused by reverse installation of the end cap.

[0037] To enhance the sealing and stability of the adsorption assembly, in this embodiment: an annular abutment plate 502 for abutting the adsorption assembly 3 is also fixedly connected to the outlet end cap 5. An abutment pad 5021 is fixedly connected to the bottom of the annular abutment plate 502. The annular abutment plate 502 and the abutment pad 5021 form a "rigid support + flexible sealing" structure.

[0038] To achieve tool-free quick locking and unlocking of the end cap, in this embodiment: both sides of the air outlet end cap 5 are equipped with snap-fit ​​fixing components 503 for fixing the air outlet end cap 5. The side of the tower body 1 and the position corresponding to the snap-fit ​​fixing component 503 are provided with a slot 5031. The snap-fit ​​fixing component 503 includes a mounting base 504 fixedly connected to the side of the air outlet end cap 5. A sliding locking rod 5041 is slidably connected to the mounting base 504. An operating block 505 is fixedly connected to the end of the sliding locking rod 5041. A connecting spring 5051 is fixedly connected to the side of the operating block 505 near the mounting base 504, and the other end of the connecting spring 5051 is fixedly connected to the side of the mounting base 504. By pulling the operating block 505, the sliding locking rod 5041 can be quickly disengaged. At the same time, the connecting spring 5051 provides a continuous preload force so that the sliding locking rod 5041 remains in the snap-fit ​​state under vibration.

[0039] The working principle of this utility model is as follows: The adsorption component 3 and the adsorption component 4, which are movably installed inside the tower body 1, are fixed by the air outlet cover 5 and the air inlet cover 6, respectively. When disassembling, it is only necessary to pull the operating block 505 on the side of the air outlet cover 5 and drive the sliding rod 5041 on the side of the operating block 505 to disengage from the slot 5031 on the side of the tower body 1, so that the air outlet cover 5 can be easily disassembled, thereby facilitating the disassembly of the adsorption component 3. When installing, it is only necessary to install the adsorption component 3 inside the tower body 1 and then cover the air outlet cover 5. First, the positioning block 501 at the bottom of the air outlet cover 5 is inserted into the positioning groove 5011 on the tower body 1, and the annular abutment plate 502 at the bottom of the air outlet cover 5 abuts against the adsorption component 3. Then, the sliding rod 5041 is inserted into the corresponding slot 5031. Under the elastic force of the connecting spring 5051, the sliding rod 5041 is driven to be firmly locked into the slot 5031.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
