The cooling mechanism includes a shell and tube condenser, and a cooling water inlet 11 and a cooling water outlet 12 connected to the shell and tube condenser. The gaseous substance in the shell and tube condenser is cooled by cooling water and cooled into condensate. The condensate flows to the liquid collecting mechanism 2 arranged below the distillation tower under the action of gravity.

[0025] See attached Figure 1 and attached Figure 2As shown, the liquid collecting mechanism 2 includes a collecting plate 21 and a fixing ring 22 for fixing the collecting plate 21. A collecting groove 23 is provided at the lower end of the collecting plate 21. The collecting plate 21 and the collecting groove 23 are both provided with a plurality of them. The condensate flows into the collecting groove 23 along the collecting plate 21. A collecting groove 24 is provided below the collecting groove 23. The condensate in the collecting groove 23 is all gathered into the collecting groove 24. A three-way valve 25 is provided at the bottom of the collecting groove 24. The condensate in the collecting groove 24 flows out of the collecting groove 24 from the three-way valve 25. The three-way valve 25 is located at the center of the collecting groove 24, which is conducive to the outflow of the condensate and the receiving of the condensate by the rotating collecting mechanism 3.

[0026] See attached Figure 1 and attached Figure 3 As shown, in some embodiments, the rotating collection mechanism 3 is arranged below the liquid collection mechanism 2, and the rotating collection mechanism 3 includes a guide member 31 and a driving assembly. The guide member 31 is located directly below the three-way valve 25, and the cup mouth of the guide member 31 is larger than the outflow port of the three-way valve 25. The guide member 31 can receive the condensate flowing out of the three-way valve 25, and the guide member 31 can also receive the condensate flowing out of the three-way valve 25 during the process of swinging in the horizontal direction under the action of the driving assembly.

[0027] In some embodiments, the driving mechanism includes a driving member 34 and a rotating arm 33, wherein the driving member 34 is connected to the rotating arm 33, and the driving member 34 can drive the rotating arm 33 to rotate, and one end of the rotating arm 33 away from the driving member 34 is connected to the swing arm 32, and the rotating arm 33 and the swing arm 32 are vertically arranged, and the other end of the swing arm 32 is connected to the guide member 31, and the rotating arm 33 can drive the swing arm 32 to move synchronously during the rotation process, thereby driving the guide member 31 to swing in the horizontal direction. In order to better drive the guide member 31 to swing through the swing arm 32, one end where the swing arm 32 and the rotating arm 33 are connected is a spherical structure, named as the spherical end 321, and a part of the rotating arm 33 is inserted into the spherical end 321, and the rotating arm 33 and the spherical end 321 can remain relatively still.

The liquid in the collecting trough 23 is drained to the outside of the collecting cup 35 through the guide member 31, allowing the condensate to flow into the tower body below for secondary distillation.
