[0022] Mounting grooves 14 are arranged on both sides of the dehydration tank 1, and a mounting frame 15 is arranged in cooperation with the mounting grooves 14, a molecular sieve plate 16 is installed on the mounting frame 15, and a sealing plate 17 is installed on the outer wall of the mounting frame 15;

[0024] A limiting mechanism is arranged in the dehydration tank 1 and is close to the mounting groove 14, which is used for limiting and fixing the mounting frame 15.

[0025] When it is necessary to replace the molecular sieve plate 16 in one side of the flow guide channel 4, the driving mechanism is driven to rotate the rotating shaft 7, thereby driving the rotating disc 8 to rotate, so that the second flow channel 9 on the rotating disc 8 is out of alignment with the first flow channel 6 on the fixed disc 5, thereby achieving blocking of the flow guide channel 4 on the side, and in the process of driving the driving mechanism, the limiting mechanism is also released from limiting the sealing plate 17, at this time, the mounting rack 15 can be pulled out from the mounting groove 14, and then the new molecular sieve plate 16 is replaced, when the replacement of the new molecular sieve plate 16 is completed and the mounting rack 15 is inserted into the mounting groove 14, the driving mechanism is driven to reverse the rotating shaft 7, so that the second flow channel 9 on the rotating disc 8 is aligned with the first flow channel 6 on the fixed disc 5, at this time, the flow guide channel 4 on the side starts to flow, and the limiting mechanism is limited to the sealing plate 17, achieving the installation of the molecular sieve plate 16, the whole replacement process is relatively simple, and when the molecular sieve plate 16 is replaced, only the flow guide channel 4 on a single side is blocked, so that the production and transportation of the gas flow are not affected, and the use effect is better.

[0026] In one case of the embodiment, the first flow channel 6 and the second flow channel 9 are correspondingly arranged.

[0027] In the embodiment, the rotating disc 8 and the fixed disc 5 are the same in size, and the first flow channel 6 and the second flow channel 9 are arranged at the same position, when the first flow channel 6 and the second flow channel 9 are aligned, at this time, the flow guide channel 4 on the side can normally flow the gas, and when the first flow channel 6 and the second flow channel 9 are out of alignment, at this time, the fixed disc 5 and the rotating disc 8 are in a closed state, and the flow guide channel 4 on the side cannot normally flow the gas, thereby facilitating the replacement of the molecular sieve plate 16.

[0028] In one case of the embodiment, the driving mechanism includes a sliding rod 11 slidingly arranged on both sides of the dehydration tank 1, a rack 12 is installed on one end of the sliding rod 11 penetrating into the flow guide channel 4, a gear 10 engaged with the rack 12 is installed on the rotating shaft 7, and a linear motor 13 connected with the sliding rod 11 is installed on both sides of the dehydration tank 1.

[0029] In the embodiment, when it is necessary to replace the molecular sieve plate 16, the linear motor 13 is started by an external controller, the linear motor 13 drives the sliding rod 11 to move, thereby driving the rotating shaft 7 to rotate through the engaged rack 12 and gear 10, so that the rotating disc 8 rotates, thereby causing the first flow channel 6 on the fixed disc 5 and the second flow channel 9 on the rotating disc 8 to be out of alignment and achieve blocking.

[0030] In one case of the embodiment, the sealing plate 17 is provided with a limiting rod 19 at both ends, and the dehydrating tank 1 is provided with a limiting slot 18 at both sides, which is in sliding cooperation with the limiting rod 19.

[0032] When the molecular sieve plate 16 is installed, the limiting rod 19 and the limiting slot 18 can assist the installation frame 15 to be correctly installed in the installation slot 14, and when the sliding rod 11 is moved by the linear motor 13, the connecting rod 24 hinged to the sliding rod 11 pulls the sliding frame 21 to move upward, so that the clamping block 22 on the sliding frame 21 is out of the clamping slot 23 of the limiting rod 19, thereby releasing the limiting of the sealing plate 17, at this time, the installation frame 15 can be pulled out from the installation slot 14, and when the installation is completed, the linear motor 13 drives the sliding rod 11 to move reversely, at this time, the connecting rod 24 drives the sliding frame 21 to move downward, so that the clamping block 22 is clamped into the clamping slot 23 of the limiting rod 19, thereby limiting the sealing plate 17, that is, the installation of the installation frame 15 and the molecular sieve plate 16 is completed.
