[0024] As Figures 1 - 5 shown, the present utility model provides the following technical solutions: A dehydration tank, including a dehydration tank 1, a box body 2 is slidably arranged through the dehydration tank 1, through holes are opened on both the top surface and the bottom surface of the box body 2, a plurality of cavities 3 are horizontally arranged in the box body 2, each cavity 3 can independently slide into the dehydration tank 1, and desiccant particles 4 are contained in the cavity 3 to perform drying operation on the gas. A positioning mechanism is fixedly connected to the top surface of each cavity 3, and the positioning mechanism can position the sliding cavity 3.

[0025] Please combine Figure 1As shown, during use, acetylene gas containing moisture is introduced into the dehydration tank 1 for dehydration treatment. As the desiccant particles 4 in the dehydration tank 1 adsorb more and more moisture, the performance of the desiccant particles 4 decreases. When the desiccant particles 4 in the dehydration tank 1 need to be replaced, the staff pushes the box body 2 to move. The box body 2 drives the cavity 3 to move, and the cavity 3 drives the internal desiccant particles 4 to move, so that new desiccant particles 4 enter the dehydration tank 1. The desiccant particles 4 that have reached saturation are driven by the cavity 3 to slide out of the dehydration tank 1. There is no need to stop the machine and then disassemble and replace the drying particles, which saves time and shortens the processing cycle. The desiccant particles 4 located outside are dried in the sun for the next use.

[0026] The cavity 3 is partitioned by a partition plate 6. The partition plate 6 is arranged in the box body 2 and fixedly connected to its inner wall. The cavity 3 has a feed port and a plurality of air holes. The feed port is opened on the top surface of the box body 2, and the air holes are opened on the surface of the box body 2.

[0027] Please combine Figure 1 As shown, during use, the acetylene gas to be treated is introduced from the input end of the dehydration tank 1, and dehydration treatment is carried out through the desiccant particles 4 in the dehydration tank 1. The treated acetylene gas is then discharged from the output end of the dehydration tank 1 to the next stage. When the desiccant particles 4 in the dehydration tank 1 need to be replaced, the staff pushes the box body 2 to move. The box body 2 drives the partition plate 6 to move. The partition plate 6 divides the internal volume of the box body 2 into multiple cavities 3, so that multiple cavities 3 can work independently. The acetylene gas passes through the box body 2 through a plurality of air holes. The cavity 3 has a feed port to facilitate the replacement of the internal desiccant particles 4.

[0028] Please combine Figures 1 - 4 As shown, an embodiment of the positioning mechanism. The positioning mechanism includes a chute 7. The chute 7 is opened on the top surface of the box body 2. A slide plate 8 is slidably arranged through the chute 7. Both the top surface and the bottom surface of the slide plate 8 are arc surfaces. The side wall of the slide plate 8 is attached to the side wall of the dehydration tank 1. A dovetail block 10 is fixedly connected to the side wall of the slide plate 8. The dovetail block 10 is slidably arranged in a dovetail groove 9. The dovetail groove 9 is opened on the side wall of the partition plate 6. A return spring 11 is fixedly connected between the dovetail block 10 and the partition plate 6. The return spring 11 is arranged in the dovetail groove 9.

[0029] Please combine Figure 1As shown, during use, when the staff member pushes the box body 2 to move, the box body 2 drives the partition plate 6 to move, the partition plate 6 drives the sliding plate 8 to move horizontally, the sliding plate 8 drives the sliding plate 8 to move. When the sliding plate 8 moves and fits against the side wall of the dehydration tank 1 and continues to move, the dehydration tank 1 pushes the sliding plate 8 to move downward. The sliding plate 8 drives the dovetail block 10 to move and squeeze the return spring 11 to deform. When the sliding plate 8 moves and separates from the side wall of the dehydration tank 1, at this time, the deformed return spring 11 pushes the dovetail block 10 to move, and the dovetail block 10 drives the sliding plate 8 to move back to its original position. When the cavity 3 is replaced, at this time, the side wall of the sliding plate 8 just fits against the side wall of the dehydration tank 1, realizing the positioning operation of the sliding plate 8 during the movement of the cavity 3. The top surface of the sliding plate 8 is an arc surface to facilitate the dehydration tank 1 to push the sliding plate 8 to move. The bottom surface of the sliding plate 8 is an arc surface. During the downward movement of the sliding plate 8, the arc surface of the bottom surface of the sliding plate 8 can push the desiccant particles 4 to move sideways, preventing the desiccant particles 4 from affecting the sliding of the sliding plate 8.

[0030] A frame 12 is slidably arranged in the cavity 3. The frame 12 is slidably embedded in the inner bottom surface of the box body 2. The top surface of the frame 12 is in the same plane as the inner bottom surface of the box body 2. The top surface of the frame 12 is fixedly connected to the bottom surface of the sliding plate 8. A positioning ring 13 is fixedly connected in the dehydration tank 1, and the bottom surface of the positioning ring 13 can fit against the sliding plate 8.

[0031] Please combine Figure 3 As shown, during use, when the staff member pushes the box body 2 to move, the box body 2 drives the frame 12 in the dehydration tank 1 to move. The box body 2 indirectly drives the sliding plate 8 to move and separate from the positioning ring 13 in the dehydration tank 1. At this time, the return spring 11 indirectly drives the sliding plate 8 to move. The sliding plate 8 drives the frame 12 to move upward. The frame 12 drives the desiccant particles 4 on its top surface to move, changing the contact surface between the desiccant particles 4 and reducing the adhesion between the desiccant particles 4, facilitating the drying of the desiccant particles 4 that slide out of the dehydration tank 1. The sliding plate 8 that gradually slides into the dehydration tank 1 gradually fits against the side wall of the positioning ring 13. The positioning ring 13 pushes the sliding plate 8 to move downward. The sliding plate 8 drives the frame 12 that enters the dehydration tank 1 to move downward and is embedded in the box body 2 again.

[0032] A plurality of rollers 14 are horizontally rotatably arranged in the cavity 3. The rollers 14 are rotatably connected in the through grooves 15 by pins. The through grooves 15 are opened on the bottom surface of the box body 2. The bottom surface of the rollers 14 is in the same plane as the bottom surface of the box body 2. The top surface of the rollers 14 is higher than the inner bottom surface of the box body 2. The cross-sectional shape of the rollers 14 is in the shape of a sugar-coated haws, facilitating the acetylene gas to enter the cavity 3.

[0033] Please combine Figure 1As shown, during use, when the staff pushes the box body 2 to move, the box body 2 drives the rollers 14 at the bottom to pass over the surface of the dehydration tank 1. The dehydration tank 1 pushes the rollers 14 to rotate, and the rollers 14 drive the desiccant particles 4 in the corresponding cavities 3 to move, changing the contact surfaces between the desiccant particles 4, reducing the adhesion between the desiccant particles 4, and facilitating the drying of the desiccant particles 4 that slide out of the dehydration tank 1.

[0034] Two sealing rings 5 are fixedly embedded on the outer wall of the box body 2. The two sealing rings 5 are arranged at both ends of the box body 2 and are attached to its surface.

[0035] Please refer to Figure 1 As shown, during use, the setting of the two sealing rings 5 ensures the sealing between the dehydration tank 1 and the box body 2, effectively preventing the leakage of acetylene gas and facilitating the treatment of acetylene gas.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
