Description

Technical Field

[0001] This utility model relates to the field of molecular sieve tooling for oxygen generators, specifically a molecular sieve pressing tooling for oxygen generators. Background Technology

[0002] Molecular sieves are oxygen separation devices in a system, mainly composed of molecular sieves and electric valves. They can separate oxygen from other gases in compressed air by utilizing the pressure swing adsorption characteristics of molecular sieves, concentrating the oxygen before outputting it. Typically, an AB dual-tower alternating adsorption oxygen generation method is used. One molecular sieve adsorption tower is filled with high-pressure gas and is in an adsorption state, while the other is in a low-pressure gas desorption and regeneration state. Under control commands, the two adsorption towers are connected to high-pressure or low-pressure gas at different times through control valves, and the adsorption and desorption regeneration process is repeated alternately.

[0003] There are many drawbacks in the current method of pressing the dual towers inside the molecular sieve of oxygen generators. The traditional manual pressing of the dual towers of molecular sieves is inefficient. In addition, manual installation can lead to inconsistent pressing force and pressing distance between the two towers of the same molecular sieve module, which greatly affects the overall performance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a molecular sieve pressing tool for oxygen generators to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A molecular sieve pressing fixture for an oxygen generator includes a fixed base, an adjusting bracket, a quick clamp, a limiting pressing assembly, and a molecular sieve. The molecular sieve is clamped onto the fixed base, the adjusting bracket is fixed to one side of the fixed base, the quick clamp is adjustablely connected to the adjusting bracket, and the limiting pressing assembly is connected to the adjusting bracket.

[0007] The limiting pressing assembly includes a transition main plate, a limiting flange, a limiting shaft, and an elastic pressing component. The transition main plate is fixed on the limiting flange, and the limiting shaft passes through the limiting flange, with its upper and lower ends fixed on the adjusting bracket. Two sets of elastic pressing components are provided and symmetrically connected below the transition main plate. The limiting pressing component, in conjunction with the quick clamp, simultaneously presses the left and right towers inside the molecular sieve, ensuring consistent pressing force and distance between the left and right towers, improving overall performance and installation efficiency, and ensuring consistency in pressing both towers each time. In addition, the adjusting plate of the adjusting bracket can adjust the connection position with the quick clamp to adapt to different types of molecular sieves, and the model of the elastic element can be changed to adapt to different pressure levels.

[0008] Preferably, the elastic pressing assembly includes an elastic element, a top block, a pressing seat, and a pressing block. One end of the elastic element is embedded in the bottom surface of the transition main board, and the other end is embedded in the top block. The top block is connected to the pressing seat, and the pressing block is detachably connected to the pressing seat.

[0009] Preferably, the adjusting bracket is provided with an adjusting plate.

[0010] Preferably, the adjusting plate is provided with threaded connection holes.

[0011] Preferably, the quick clamp is adjustable to the threaded connection hole of the adjusting plate.

[0013] Compared to existing technologies, this utility model discloses a molecular sieve pressing fixture for an oxygen generator, including a fixed base, an adjusting bracket, a quick clamp, a limiting pressing component, and a molecular sieve. These five components work together to achieve their functions. The limiting pressing component and the quick clamp work together to simultaneously press the left and right towers inside the molecular sieve, ensuring that the pressing force and pressing distance of the left and right towers are consistent, thereby improving the overall performance and overall installation efficiency, and ensuring the consistency of pressing the two towers each time. In addition, the adjusting plate of the adjusting bracket can also adjust the connection position with the quick clamp to adapt to different types of molecular sieves, and change the type of elastic element to adapt to different pressure levels.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] A molecular sieve pressing fixture for an oxygen generator includes a fixed base 1, an adjusting bracket 2, a quick clamp 3, a limiting pressing assembly 4, and a molecular sieve 5. The molecular sieve 5 is clamped onto the fixed base 1. The adjusting bracket 2 is fixed to one side of the fixed base 1. The quick clamp 3 is adjustablely connected to the adjusting bracket 2. The limiting pressing assembly 4 is connected to the adjusting bracket 2.

[0019] The limiting pressing assembly 4 includes a transition main plate 41, a limiting flange 42, a limiting shaft 43, and an elastic pressing assembly 44. The transition main plate 41 is fixed on the limiting flange 42, and the limiting shaft 43 passes through the limiting flange 42. The upper and lower ends of the limiting shaft 43 are fixed on the adjusting bracket 2. There are two sets of elastic pressing assemblies 44, which are symmetrically connected below the transition main plate 41. The double towers of the molecular sieve 5 are the left and right towers.

[0020] The elastic pressing assembly 44 includes an elastic element 441, a top block 442, a pressing seat 443, and a pressing block 444. One end of the elastic element 441 is embedded in the bottom surface of the transition main plate 41, and the other end is embedded in the top block 442. The top block 442 is connected to the pressing seat 443, and the pressing block 444 is detachably connected to the pressing seat 443. The model of the elastic element 441 can be selected according to the actual working conditions.

[0021] The adjusting bracket 2 is provided with an adjusting plate 21, and the adjusting plate 21 is provided with a threaded connection hole. The quick clamp 3 is adjustablely connected to the threaded connection hole of the adjusting plate 21. The fixed base 1 is provided with a foot pad to stabilize the fixed base 1.

[0022] Working mode: The operator first clamps the molecular sieve 5 onto the fixed base 1, and then adjusts the fixed position of the quick clamp 3 on the adjusting plate 21 according to the depth of the left and right towers inside the molecular sieve 5. Pressing down the quick clamp 3 causes the limiting flange 42 of the transition main plate 41 and the axis of the limiting shaft 43 to move down accordingly. The pressing block 444 contacts the left and right tower components inside the molecular sieve 5. The elastic element 441 continues to compress and deform during the downward pressing process until the left and right tower components inside the molecular sieve 5 are installed in place. The above steps are repeated to return to the initial state.
