The sleeve 508 is controlled to rotate by the rocker 503, and a first protrusion 505 and a second protrusion 506 are provided on the rocker 503. A first sliding groove matching the first protrusion 505 is opened on the inner wall of the short sleeve 507, and a second sliding groove matching the second protrusion 506 is opened on the inner wall of the long sleeve 508. The length of the first sliding groove is equal to that of the first protrusion 505, and the length of the second sliding groove is at least twice that of the second protrusion 506.

At this time, turning the handle 504 can drive the second pulley group 502 to rotate. When the first protrusion 505 is inserted into the first sliding groove, turning the handle 504 can drive the first pulley group 501 and the second pulley group 502 to rotate at the same time.

[0022] A limiting groove 102 is provided on the outer wall of the tower body 1, and the sealing plate 7 is located in the limiting groove 102 and fixedly connected to the outer wall of the movable feed port 3; a gear 9 is threadedly connected to the movable feed port 3, and an arc block 8 that fits the outer surface of the tower body 1 is provided on the side of the gear 9 close to the tower body 1, and the arc block 8 is sleeved on the movable feed port 3.

[0023] The arc block 8 fits tightly against the outer wall of the tower body 1 and can slide up and down, and the gear 9 fits tightly against the arc block 8 and can rotate relatively. When the gear 9 rotates, the movable feed port 3 and the sealing plate 7 can be driven to move along the axial direction of the gear 9, thereby pressing the sealing plate 7.

[0024] The second pulley block 502 is connected to a rack 10 meshing with the gear 9, a guide groove 101 is provided on the outer wall of the tower body 1, and one side of the rack 10 is slidably connected to the guide groove 101 through a guide rod; the first pulley block 501 is connected to a sleeve ring 6, and the sleeve ring 6 is fixedly connected to the movable feed port 3; the outer wall of the tower body 1 is provided with a plurality of fixing plates 511 for fixing the first pulley block 501 and the second pulley block 502; the outer wall of the tower body 1 is also provided with a fixed feed port 4, and the fixed feed port 4 and the movable feed port 3 are staggered in the vertical direction; at least eight layers of fillers 2 are vertically distributed in the tower body 1.

The rack 10 can only move in the vertical direction through the limitation of the guide rod, and is used to rotate the gear 9; the height of the distillation tower is 49m, so the height of the packing 2 is increased to 2.5m, the number is increased to eight, the channel is large, and the gas blockage in the tower is effectively avoided, thereby improving the smoothness of the distillation tower operation.

[0026] The fixed feed port 4 is arranged in the middle of the tower body 1, which has a higher utilization rate. The movable feed port 3 is arranged in the upper and lower parts of the tower body 1, which has a wider applicability. Reasonable adjustment of the feed position according to different feed components can not only reduce the burden on the equipment, but also improve the utilization rate of the equipment and the purity of the finished product.

[0027] Working principle: When the movable feed port 3 needs to be used, the corresponding rocker 503 is pushed to insert the first protrusion 505 into the short sleeve 507, and then the crank 504 is turned to rotate the short sleeve 507 and the long sleeve 508 at the same time, thereby driving the first pulley group 501 and the second pulley group 502 to rotate synchronously to adjust the height of the movable feed port 3. After adjusting to a suitable position, the rocker 503 is pulled to disengage the first protrusion 505 from the short sleeve 507, and then the crank 504 is turned to rotate the long sleeve 508 alone, thereby driving the rack 10 on the second pulley group 502 to move up and down.
