[0025] In an embodiment of the utility model, the top end surface of fixed frame 501 is fixedly connected with guide cover 502, fixed frame 501 is fixedly connected in the inner wall of kettle body 1, guide cover 502 is fixedly connected in the inner wall of kettle body 1, fixed frame 501 is rotatably connected with vertical rod 503, the side wall of vertical rod 503 is fixedly connected with blade 504, blade 504 is movably connected with the inner wall of guide cover 502, the axis of guide cover 502 coincides with the axis of vertical rod 503, solution vapor moves upwards and pushes blade 504 and vertical rod 503 to rotate, the outer wall of vertical rod 503 is fixedly connected with rotating seat 505, the outer wall of rotating seat 505 is fixedly connected with rotating rod 506.
[0026] The outer wall of the connecting block 507 is provided with a limiting groove 508, the limiting groove 508 is in sliding connection with a limiting rod 510, the end face of the limiting rod 510 is fixedly connected with a ventilation plate 509, the outer wall of the limiting rod 510 is fixedly connected with a protrusion 511, the inner wall of the kettle body 1 is fixedly connected with a fixed ring 512, the inner wall of the fixed ring 512 is provided with a vertical groove 513, the vertical groove 513 is in sliding connection with the protrusion 511, the top end face of the ventilation plate 509 is provided with a through hole, the number of the through hole is provided with several groups, and the several groups of through holes are equidistantly arranged on the top end face of the ventilation plate 509. The connecting block 507 is fixedly connected to the outer wall of the vertical rod 503. The solution vapor can move upward through the through hole on the ventilation plate 509.
[0027] The heating pipe 4 heats the kettle body 1, the solution in the kettle body 1 is heated, the vapor generated by heating moves upward, is discharged from the kettle body 1 through the gas outlet 2, reaches the downstream equipment, the upward movement of the vapor drives the blade 504 to rotate, and then drives the vertical rod 503 and the connecting block 507 to rotate, so that the limiting groove 508 rotates, and then guides the ventilation plate 509 to reciprocate longitudinally. The ventilation plate 509 hits the foam, which can break the foam, reduce the volume and stability of the foam, and prevent the foam from accumulating and entering the gas outlet 2 upward. This hitting action can help break the bubbles in the foam, so that they no longer rise with the airflow, thereby reducing the influence of the foam on the vapor flow.

During the distillation process, especially in a vacuum environment, the bubbles may maintain a certain activity and buoyancy due to the high temperature. By cooling the rotating rod 506 and making it contact with the bubbles, the temperature of the bubbles can be effectively reduced. The cooling effect can reduce the surface temperature of the bubbles and increase the surface tension, thereby accelerating the coagulation or rupture of the bubbles. By cooling the surface of the bubbles, the gas in the bubbles contracts, causing the volume of the bubbles to shrink or rupture. After the bubbles rupture, not only the number of bubbles is reduced, but also they are prevented from further rising through the airflow and being brought into the gas outlet 2.
