Description

Technical Field

[0001] This utility model relates to the field of gas separation equipment technology, and in particular to an upper pressing device for a nitrogen generator. Background Technology

[0002] In nitrogen generators (especially PSA nitrogen generators), the column is filled with adsorbents such as molecular sieves. During the continuous adsorption-desorption cycle, the pressure inside the column undergoes periodic and drastic changes (from high-pressure adsorption to atmospheric or negative-pressure desorption). This pressure alternation can cause phenomena such as "bed settling" or "adsorbent particle friction," requiring the use of a compaction device to compress the packing material.

[0003] For example, a nitrogen generator upper clamping device with publication number CN221580157U relates to the technical field of nitrogen generator equipment. This utility model includes an upper sieve plate with vent holes having a diameter smaller than the packing diameter. The upper sieve plate is fixedly connected to the inner wall of the pressure cap, and an outer sliding cylinder is concentrically fixed at its bottom. An inner sliding cylinder is fitted inside the outer sliding cylinder, and the inner sliding cylinder is perpendicularly fixed to the lower sieve plate, allowing the outer and inner sliding cylinders to slide relative to each other. It also includes an elastic mechanism disposed between the upper and lower sieve plates to continuously provide clamping force to the lower sieve plate. This design structure ensures that when the pressure cap is locked onto the packing cylinder, the upper sieve plate, through the outer sliding cylinder, acts on the lower sieve plate, compressing the packing. When the packing inside the packing cylinder is shaken for a long time, gaps exist at the top. Driven by the elastic mechanism, the lower sieve plate moves downwards to further compact the packing, avoiding uneven compaction that could lead to impure nitrogen production. However, the upper clamping device of the nitrogen generator uses the elasticity of a spring to press the packing material, and the pressure is not adjustable, making it unable to adapt to different filling heights or adsorbent types. Furthermore, it is impossible to visually observe the pressing condition of the packing material, making it difficult to judge the loss of the packing material and the density of the bed.

[0004] Therefore, a nitrogen generator upper clamping device has now been developed that can adjust the clamping force on the filler and allow for intuitive observation of the positional changes of the push rod. Utility Model Content

[0005] To overcome the shortcomings of existing nitrogen generator upper clamping devices, which use spring elasticity to clamp the packing material, have unadjustable pressure, cannot adapt to different filling heights or adsorbent types, and cannot visually observe the clamping condition of the packing material, making it difficult to judge the packing material loss and bed density, this utility model provides a nitrogen generator upper clamping device that can adjust the clamping force of the packing material and visually observe the position change of the push rod.

[0006] The technical implementation scheme of this utility model is as follows: A nitrogen generator upper clamping device includes a tank, a sealing gasket, locking bolts, a mounting plate, a sleeve, an observation component, and a clamping component. A sealing gasket is connected to the upper side of the tank. A mounting plate is detachably connected to the upper side of the tank through multiple locking bolts. The mounting plate is in contact with the sealing gasket. A sleeve is connected to the upper side of the middle part of the mounting plate. An observation component for observing adsorbent loss is provided on the sleeve. A clamping component for clamping the adsorbent is also provided on the sleeve.

[0007] In a preferred embodiment of the present invention, the observation component includes an observation window and scale lines. The observation window is connected to the front side of the sleeve, and the observation window is provided with scale lines.

[0008] In a preferred embodiment of the present invention, the clamping assembly includes a screw, a threaded sleeve, a pad, an elastic element, a push rod, and a soft pad. The upper side of the sleeve is connected to the threaded sleeve, the threaded sleeve is threadedly connected to the screw, the lower side of the screw is rotatably connected to the pad, the pad is slidably connected to the sleeve, the lower part of the sleeve is slidably connected to the push rod, the push rod is connected to the pad with an elastic element, and the lower side of the push rod is connected to the soft pad.

[0009] In a preferred embodiment of this utility model, the elastic element is a spring.

[0010] In a preferred embodiment of the present invention, a rotating handle is also included, with the rotating handle connected to the upper side of the screw.

[0011] In a preferred embodiment of the present invention, a sealing ring is also included, and the sealing ring is connected to the soft pad.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention rotates the screw by gripping the rotating handle, so that the screw moves on the threaded sleeve, pushes the pad to move, adjusts the distance between the pad and the top rod, and adjusts the compression of the spring, thereby achieving the effect of adjusting the clamping force on the filler and precisely controlling the amount of clamping force applied to the adsorbent bed.

[0013] 2. This utility model allows for observation of the top rod position through an observation window. As the adsorbent bed settles, the top rod moves downwards accordingly. The positional change of the top rod can be observed through the scale lines, thus enabling the determination of the loss of the packing material and the density of the bed, facilitating timely replacement of the adsorbent.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A nitrogen generator upper clamping device, such as Figures 1-4 As shown, it includes a tank body 1, a sealing gasket 2, locking bolts 3, a mounting plate 4, a sleeve 5, an observation component, and a clamping component. The sealing gasket 2 is connected to the upper side of the tank body 1. The mounting plate 4 is detachably connected to the upper side of the tank body 1 through six locking bolts 3. The mounting plate 4 is in contact with the sealing gasket 2. The sleeve 5 is connected to the upper side of the middle part of the mounting plate 4. The observation component is provided on the sleeve 5. The clamping component is also provided on the sleeve 5.

[0021] like Figure 2 As shown, the observation component includes an observation window 6 and a scale line 7. The observation window 6 is connected to the front side of the sleeve 5, and the scale line 7 is provided on the observation window 6.

[0022] like Figures 1-4 As shown, the clamping assembly includes a rotating handle 8, a screw 9, a threaded sleeve 10, a pad 11, an elastic element, a push rod 13, a soft pad 14, and a sealing ring 15. The upper side of the sleeve 5 is connected to the threaded sleeve 10, and the threaded sleeve 10 is threadedly connected to the screw 9. The upper side of the screw 9 is connected to the rotating handle 8, and the lower side of the screw 9 is rotatably connected to the pad 11. The pad 11 is slidably connected to the sleeve 5. The lower part of the sleeve 5 is slidably connected to the push rod 13, and an elastic element, which is a spring 12, is connected between the push rod 13 and the pad 11. The lower side of the push rod 13 is connected to the soft pad 14, and the soft pad 14 is connected to the sealing ring 15.

[0023] When using this utility model, first fill the adsorbent into the tank 1, and then install the mounting plate 4 on the tank 1 by tightening the bolts 3. The sealing gasket 2 is used to enhance the sealing between the tank 1 and the mounting plate 4. At this time, the soft pad 14 on the top rod 13 is pressed down on the upper side of the adsorbent by the force of the spring 12, and the adsorbent is compressed. The soft pad 14 can prevent the adsorbent from being crushed. The sealing ring 15 contacts the inner wall of the tank 1 to prevent the adsorbent from escaping. The position of the top rod 13 can be observed through the observation window 6. When the adsorbent bed settles, the top rod 13 moves down accordingly. The position change of the top rod 13 can be observed through the scale line 7, so as to judge the loss of the packing material and the density of the bed, so as to replace the new adsorbent in time. When compacting the adsorbent, the screw 9 can be rotated by grasping the rotating handle 8 according to different adsorbent filling heights, adsorbent types, or operating requirements. This causes the screw 9 to move on the threaded sleeve 10, pushing the pad 11 to move. The distance between the pad 11 and the top rod 13 can be adjusted, and the compression of the spring 12 can be adjusted, thereby precisely controlling the magnitude of the compaction force applied to the adsorbent bed.

[0024] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
