[0014] The present invention has the following beneficial effects: (1) In the present invention, the mixture and the high-pressure gas are poured into the interior of the distillation tower through the feed pipe, and the heater is turned on to increase the temperature. The heat generated is transferred to the heating shell. The heat energy of the heating shell heats the falling mixture to separate the gas and liquid. At the same time, the air pump is started to generate negative pressure inside the reflux pipe. The negative pressure absorbs the liquid staying on the top of the fixed platform, so that the liquid enters the top of the distillation tower through the reflux pipe, thereby performing reflux separation, so that the liquid stays on the top of the fixed shell. When the high-pressure airflow moves upward, the air pressure generated causes the sliding cylinder to move vertically upward along the inner wall of the fixed shell. At this time, the high-pressure airflow enters the interior of the fixed shell. Through the setting of the air holes, the airflow enters the interior of the sliding cylinder through the air holes, and then the airflow passes through the air holes and the solid The liquid on the top of the fixed shell is in contact with the sliding cylinder, thereby improving the working efficiency of the distillation; when the sliding cylinder moves upward, the sliding cylinder drives the fixed ring to move upward, the fixed ring drives the rotating plate to move upward, and is limited by the sliding groove. The rotating plate drives the sliding block to move along the outer wall of the sliding groove, and is limited by the arc hole setting of the arc groove plate. During the movement of the sliding block, the arc groove plate will rotate in a circle along the center of the inner wall of the fixed shell, and the arc groove plate drives the rotating ring shell to rotate. Limited by the limiting groove, the rotating ring shell drives the limiting block to rotate, the limiting block drives the lifting ring to rotate, the lifting ring drives the bending rod to rotate, and the bending rod drives the stirring plate to rotate. During the rotation of the stirring plate, the bubbles generated in the gas-liquid mixture will be crushed to prevent large bubbles from being generated during the rising process of the gas, thereby indirectly improving the distillation effect of the gas and liquid.

[0015] (2) In the present invention, when the bent rod rotates, the bent rod drives the annular plate to rotate, and the annular plate drives the conical filter plate to rotate. When the liquid falls, it will come into contact with the top of the conical filter plate, and the impurity particles in the liquid will be blocked by the conical filter plate. At this time, the conical filter plate can throw off the impurity particles stuck in the filter holes of the conical filter plate during the rotation process, thereby improving the gas-liquid fractionation effect. At the same time, the sliding cylinder drives the connecting plate to move upward, and the connecting plate drives the sliding frame to move upward. During the upward movement of the sliding frame, the annular plate is moved upward. The annular groove limits the position of the annular plate, which can prevent the annular plate from getting stuck during the upward movement. The annular plate drives the conical filter plate to move vertically upward. At this time, the conical filter plate can make the impurity particles enter the interior of the annular filter shell during the process of throwing off the impurity particles, thereby further improving the gas-liquid fractionation effect. When the liquid and the impurity particles enter the interior of the annular filter shell together, the filter holes of the annular filter shell are set, and the liquid enters the top of the fixed shell through the filter holes.

[0016] (3) In the present invention, when the conical filter plate moves upward, the conical filter plate drives the vertical rod to move upward, the vertical rod drives the rotating bar to move upward, and is limited by the limit frame. The rotating bar drives the sliding plate to slide along the outer wall of the limit frame, the sliding plate drives the vertical plate to move, and the vertical plate drives the impact frame to move. During the movement of the impact frame, it will collide with the side wall of the upward-moving conical filter plate, causing the conical filter plate to vibrate slightly, which cooperates with the inclined surface setting of the conical filter plate to allow impurity particles to enter the interior of the annular filter shell, further improving the separation effect of impurity particles. When the compressed gas is not enough to make the sliding cylinder move upward, the elastic deformation of the spring causes the connecting plate to drive the sliding cylinder to vertically descend, and at the same time the conical filter plate moves downward, and the conical filter plate drives the extrusion rod to descend. During the descending process of the extrusion rod, the top of the blocking block is pressed down, so that the blocking block no longer blocks the conical mouth of the conical tube, so that the liquid on the top of the fixed shell can enter the interior of the conical tube, and the liquid falls downward through the conical tube and then stays on the top of the fixed platform. When the distillation work is completed, the connecting port of the discharge pipe is opened to allow the liquid to be discharged to the outside.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] When in use, the mixture and the high-pressure gas are poured into the interior of the distillation tower 1 through the feed pipe 4, and the heater 53 is turned on. The heater 53 is heated up, and the heat generated is used for heat transfer to the heating shell 52. The heat energy of the heating shell 52 heats the falling mixture to separate the gas and liquid. At the same time, the air pump 7 is started, and the air pump 7 generates a negative pressure inside the reflux pipe 8. The negative pressure absorbs the liquid staying on the top of the fixed platform 51, so that the liquid enters the top of the distillation tower 1 through the reflux pipe 8, thereby performing reflux separation, so that the liquid will stay on the top of the fixed shell 551. When the high-pressure airflow moves upward, the air pressure generated causes the sliding cylinder 553 to move vertically upward along the inner wall of the fixed shell 551. At this time, the high-pressure airflow enters the interior of the fixed shell 551. Through the setting of the air hole 555, the airflow enters the interior of the sliding cylinder 553 through the air hole 555, and then the airflow contacts the liquid on the top of the fixed shell 551 through the air hole 555, thereby improving the fractionation efficiency.

The sliding groove 564 is limited, and the rotating plate 562 drives the sliding block 563 to move along the outer wall of the sliding groove 564. The arc-shaped hole setting of the arc-shaped groove plate 565 causes the arc-shaped groove plate 565 to rotate in a circle along the center of the inner wall of the fixed shell 551 during the movement of the sliding block 563. The arc-shaped groove plate 565 drives the rotating plate 562 to move along the outer wall of the sliding groove 564. The movable ring shell 566 rotates and is limited by the limit groove 5610.

The stirring plate 5612 will crush the bubbles generated in the gas-liquid mixture during its rotation to prevent large bubbles from being generated during the rising process of the gas, thereby indirectly improving the gas-liquid fractionation effect.

[0032] When the bent rod 5611 rotates, the bent rod 5611 drives the annular plate 571 to rotate, and the annular plate 571 drives the conical filter plate 573 to rotate. When the liquid falls, it will come into contact with the top of the conical filter plate 573, and the impurity particles in the liquid will be blocked by the conical filter plate 573. At this time, the conical filter plate 573 can throw away the impurity particles stuck in the filter holes of the conical filter plate 573 during its rotation, thereby improving the effect of gas-liquid fractionation. At the same time, the sliding cylinder 553 drives the connecting plate 556 to move upward, and the connecting plate 556 drives the sliding frame 574 to move upward. During the upward movement of filter element 574, the annular plate 571 is moved upward, and is limited by the annular groove 572, so that the annular plate 571 can be prevented from getting stuck during the upward movement, and the annular plate 571 drives the conical filter plate 573 to move vertically upward. At this time, the conical filter plate 573 can make the impurity particles enter the interior of the annular filter shell 552 during the process of throwing off the impurity particles, thereby further improving the gas-liquid fractionation effect. When the liquid and the impurity particles enter the interior of the annular filter shell 552 together, the liquid enters the top of the fixed shell 551 through the filter holes due to the filter hole setting of the annular filter shell 552.

[0033] When the conical filter plate 573 moves upward, the conical filter plate 573 drives the vertical rod 581 to move upward, and the vertical rod 581 drives the rotating bar 583 to move upward. Limited by the limiting frame 582, the rotating bar 583 drives the sliding plate 584 to slide along the outer wall of the limiting frame 582, and the sliding plate 584 drives the vertical plate 585 to move, and the vertical plate 585 drives the impact frame 586 to move. During the movement of the impact frame 586, it will collide with the side wall of the upward conical filter plate 573, causing the conical filter plate 573 to vibrate slightly, which cooperates with the inclined surface setting of the conical filter plate 573, so that the impurity particles can enter the interior of the annular filter shell 552, further improving the separation effect of the impurity particles. When the compressed gas is not enough to make the sliding cylinder 553 move upward, the elastic deformation of the spring 557 causes the connecting plate 556 to drive the sliding cylinder 553 to vertically descend, and at the same time, the conical filter plate 573 moves downward, and the conical filter plate 573 drives the extrusion rod 575 to descend. During the descent of the extrusion rod 575, the top of the blocking block 579 is pressed down, so that the blocking block 579 no longer blocks the conical mouth of the conical tube 576, so that the liquid on the top of the fixed shell 551 can enter the interior of the conical tube 576, and the liquid falls downward through the conical tube 576, and then stays on the top of the fixed platform 51. When the distillation work is completed, the connecting port of the discharge pipe 54 is opened to allow the liquid to be discharged to the outside.
