[0003] The Chinese utility model patent with publication number CN218307071U discloses an air dehydration device for an air separation plant, which is used to heat and analyze molecules by arranging a heating plate and a heating rod, so that the water adsorbed in the cavity of the molecular sieve is released to achieve the regeneration of the molecular sieve, and avoid the pore cavity of the molecular sieve being saturated after long-term use, thereby affecting the adsorption efficiency of water. However, the adsorption efficiency of the molecular sieve will inevitably decrease after long-term use. When the efficiency is reduced to a certain extent and the molecular sieve needs to be replaced, it is relatively inconvenient to replace it because it is not provided with a structure that facilitates the replacement of the molecular sieve. Therefore, we propose an air dehydration device for an air separation plant to solve the above problems. Utility Model Content

[0025] The present invention will be further described below in conjunction with the accompanying drawings, but the scope of protection of the present invention is not limited to the described scope.

[0026] like Figure 1 , 2 As shown in Figure 4, an air dehydration device for an air separation device includes an L-shaped drying tower body 1, an air inlet 4 is provided on the surface of the drying tower body 1 near the top, and an air outlet 5 is provided on the surface of the drying tower body 1 near the bottom, wherein the air inlet 4 is connected to the internal space of the drying tower body 1 and the air outlet 5.

[0027] Two upper and lower parallel adsorption component shells 2 are arranged inside the drying tower cylinder 1 and near the bottom. The adsorption component shells 2 are movably connected to the drying tower cylinder 1. Molecular sieves are arranged inside the adsorption component shells 2. A heating rod 8 is arranged between the two adsorption component shells 2. Several groups of first partitions 6 are fixed at intervals near the top side of the drying tower cylinder 1. Several groups of second partitions 7 are fixed inside the drying tower cylinder 1.

[0028] In order to facilitate the adsorption component housing 2 to be pulled out from the drying tower cylinder 1, Figure 3 As shown, connecting rods 3 are symmetrically arranged inside each adsorption component shell 2, one end of each connecting rod 3 extends out of the drying tower cylinder 1, and the other end of each connecting rod 3 is provided with a limiting assembly for limiting the position of the adsorption component shell 2, and the connecting rod 3 is fixedly connected to the limiting assembly.

[0029] like Figure 5 , 6 As shown, the limiting assembly includes a second limiting plate 11, a second spring 12, a push plate 13 and a linkage block 14. A limiting groove 1 is provided at the matching position between the adsorption component housing 2 and the second limiting plate 11. One end of the second limiting plate 11 is inserted into the limiting groove 1 and is rotatably connected to the groove through a rotating shaft. A push plate 13 is provided in the limiting groove 1 near the other end of the second limiting plate 11. The end of the push plate 13 is connected to the connecting rod 3. A linkage block 14 is provided on the upper surface of the second limiting plate 11 near the push plate 13. A second spring 12 is fixedly provided on the upper surface of the second limiting plate 11 near the rotating shaft, and the upper end of the second spring 12 is fixed to the inner surface of the limiting groove 1.

[0030] When the second limit plate 11 rotates around one side of the rotation axis, it will squeeze the second spring 12 fixed on the top, causing the second spring 12 to deform and generate elastic potential energy. When there is no external force interference, the second spring 12 will push the second limit plate 11 to move, causing the second limit plate 11 to return to its initial position.

[0031] The movement of the connecting rod 3 will drive the push plate 13 to move. The movement of the push plate 13 causes the two ends of the small cylinder of the linkage block 14 to be lifted along the two inclined panels 1301 respectively, so that the linkage block 14 drives the second limit plate 11 to rotate around one end of the rotating shaft, and the surface of the second limit plate 11 is separated from the contact with the grooved surface inside the outer shell of the adsorption component.

[0032] Furthermore, a small cylinder is provided on the linkage block 14 , and the push plate 13 includes a push plate body, which includes two symmetrical inclined panels 1301 , and a space for accommodating the elastic small cylinder is formed between the two inclined panels 1301 .

[0033] In order to prevent the connecting rod 3 from being separated from the interior of the adsorption component housing 2, as shown in FIG. Figure 5 As shown, a second limiting groove is provided on the outer shell 2 of the adsorption component, a first limiting plate 10 is sleeved on the connecting rod 3, the first limiting plate 10 is located in the second limiting groove, a first spring 9 is fixed on the first limiting plate 10, and the end of the first spring 9 is fixed to the inner surface of the second limiting groove.

[0034] When the connecting rod 3 moves, it will drive the first limit plate 10 fixed on the surface to move. When the first limit plate 10 moves, it will squeeze the first spring 9 in contact with the surface of the first limit plate 10, causing the first spring 9 to deform and generate elastic potential energy. When there is no external force interference, the first spring 9 will push the first limit plate 10 to move, so that the first limit plate 10 drives the connecting rod 3 back to the initial position.

[0035] In this embodiment, a button is provided at the end of the connecting rod 3 extending out of the drying tower cylinder 1. When the button is pressed, the movement of the button will drive the fixed connecting rod 3 to move. At the same time, the button can increase the contact area between the connecting rod 3 and the finger, thereby improving the comfort when pressing the connecting rod 3. A handle is fixed on the surface of the adsorption component housing 2 to facilitate pulling out the adsorption component housing 2.

[0036] The specific replacement process is as follows:

[0037] When the molecular sieve arranged inside the adsorption component shell 2 has lowered adsorption efficiency and needs to be replaced, the button is pressed to drive the connecting rod 3 to move, and the movement of the connecting rod 3 will drive the push plate 13 to move. The movement of the push plate 13 makes the two ends of the small cylinder of the linkage block 14 rise along the two inclined panels 1301 respectively, so that the linkage block 14 drives the second limiting plate 11 to rotate around one end of the rotating shaft, and makes the surface of the second limiting plate 11 break away from the contact with the grooved surface inside the adsorption component shell. At this time, the second limiting plate 11 no longer restricts the position of the adsorption component shell 2. The handle fixed on the surface of the adsorption component shell 2 can be pulled to pull the adsorption component shell 2 out of the interior of the drying tower cylinder 1, and then the molecular sieve arranged inside the adsorption component shell 2 can be replaced.

[0038] After the replacement is completed, the adsorption component shell 2 is reinserted into the interior of the drying tower cylinder 1. When the adsorption component shell 2 is inserted to a certain position, the surface of the adsorption component shell 2 will contact the surface of the second limit plate 11 and exert a certain extrusion force on the surface of the second limit plate 11, so that the second limit plate 11 rotates around one end of the rotating shaft and is inserted into the limit groove set inside the adsorption component shell 2. When one end of the second limit plate 11 is inserted into the interior of the adsorption component shell 2, the second limit plate 11 will return to the initial position through the second spring 12, and the surface of the second limit plate 11 will contact the surface of the groove inside the adsorption component shell 2, thereby limiting the position of the adsorption component shell 2 and completing the installation of the adsorption component shell 2.
