[0023] The separation component includes the extension pipe 3 being communicated with condenser 2, the lower end of the extension pipe 3 is communicated with recovery tank 4, one side of the extension pipe 3 is communicated with separation pipe 5, and functional node 6 is arranged at the position of the extension pipe 3 close to separation pipe 5, water pan 7 is slidably connected in separation pipe 5, one side of the water pan 7 is communicated with lead-out pipe 8, and the end of lead-out pipe 8 away from water pan 7 is communicated with detection device;

[0024] In this design, recovery tank 4 is used for recycling and storing output, during distillation process, user first completes preparation and liquid separation operation of organic phase in distillation tank body 1, so that distillation tank body 1 only contains organic phase, at this time, user slides lead-out pipe 8, so that water pan 7 moves into functional node 6, and uses water pan 7 to block extension pipe 3, so that output cannot flow into recovery tank 4 beyond water pan 7, then after reduced pressure operation, control heating device to heat organic phase in distillation tank body 1;

[0025] During heating process, organic phase boiling point is reduced in low pressure environment, can be converted into steam, steam is cooled when passing through condensing pipe, and then drops into water pan 7, and then enters detection device through lead-out pipe 8, at this time, user can detect output in detection device, to judge whether output meets process requirement in purity, and when purity meets requirement, user slides lead-out pipe 8 again, so that water pan 7 no longer blocks extension pipe 3, and then output can flow into recovery tank 4 through extension pipe 3, under the condition that temperature and pressure in tank body remain unchanged, can effectively reduce the generation of subsequent impurities in output, to ensure that final output meets process requirement.

[0026] Further, the detection device comprises a rotating head 9 fixedly connected with the outlet pipe 8, a plurality of elbow pipes 10 are communicated with the end of the rotating head 9 away from the outlet pipe 8, and detection bottles 11 are communicated with the end of the elbow pipes 10 away from the rotating head 9;

[0027] In this design, by arranging a plurality of elbow pipes 10, the output can be guided to different detection bottles 11 after rotating the rotating head 9, so that the output can be detected in batches to ensure the accuracy of the detection result. The detection bottles 11 can be filled with an indicator, which can be mixed with the output. The purity can be easily judged by the color change. The detection bottles 11 can be connected with the elbow pipes 10 through a connecting piece with a one-way valve. The detection bottles 11 can be taken out for detection. However, it is particularly important to ensure the sealing of the entire device to avoid the absorption of external air in the negative pressure environment, which can cause changes in air pressure.

[0029] The rubber plug 72 is arranged to block the connection point between the separation pipe 5 and the extension pipe 3 when the purity meets the requirements, and the user slides the main body 71 into the separation pipe 5 after sliding the outlet pipe 8. The sealing ring 73 is arranged to prevent the output from flowing along the gap between the extension pipe 3 and the water pan 7 to the recovery tank 4, so as to prevent the output containing impurities from flowing into the recovery tank 4 and affecting the purity of the output.

[0030] Further, the detection bottles 11 are made of transparent material, such as transparent glass, and the detection bottles 11 are communicated with the elbow pipes 10 through a hose. The hose is matched with the transparent detection bottles 11.

The vertical rod 13 is located at the middle of the extension pipe 3. This design can make the output flow along the drainage rod 12 to the vertical rod 13, and then drop down along the vertical rod 13, so that the output does not flow down along the wall of the extension pipe 3. This can improve the effect of the water pan 7 on containing the output containing the front fraction, and reduce the residue of impurities on the wall of the extension pipe 3.

[0032] Further, the inner wall of the water pan 7 is provided with a sink, and the sink is provided with a filter screen 14.
