[0029] A circulating water vacuum pump generally includes two vacuum ports. Normally, only one vacuum port is used during the evaporation extraction process. The evaporation extraction device of the present application can also connect the two vacuum ports in the same system to form an interconnected system. When the circulating water vacuum pump starts to vacuum, the two vacuum ports can work at the same time, shortening the working time, thereby improving the extraction efficiency, and achieving the effect of saving water and electricity.

[0030] In one embodiment, if Figure 1 As shown, the first connecting member 5 includes: a sealing piston connecting tube 51 and a first three-way tube 52, the sealing piston connecting tube 51 is connected to one end of the first three-way tube 52, and a first valve 53 is provided at the bottom of the first three-way tube 52, wherein the first valve 53 is used to connect or close the extraction system.

[0031] Optionally, the first connecting member 5 includes a sealing piston connecting pipe 51 and a first three-way pipe 52. One side of the sealing piston connecting pipe 51 is connected to the rotary evaporation device 1, and the other side of the sealing piston connecting pipe 51 is connected to any end of the first three-way pipe 52, such as the upper end of the first three-way pipe is connected to the other side of the sealing piston connecting pipe 51.

The first valve 53 can be opened or closed. When the evaporation extraction device is powered on, the first valve 53 can be used to connect or close the extraction system. It should be noted that the side of the first three-way pipe 52 connected to the sealing piston connecting pipe 51 and the side of the bottom connected to the first valve 53 cannot be the same side. At this time, the first three-way pipe 52 has been connected to both sides, and one side can be connected to the second connecting member 6, thereby forming a closed system.

[0032] In one embodiment, the sealing piston connecting pipe 51 can be a plastic pipe for a compressor or a plastic pipe for a vacuum pump. The first three-way pipe 52 can be an acrylonitrile-butadiene-styrene copolymer plastic three-way pipe, a nylon three-way pipe or a five-toxic plastic three-way pipe.

[0033] In one embodiment, Figure 1 As shown, the second connecting member 6 includes: a second three-way pipe 61, and a second valve 62 is provided at one end of the second three-way pipe 61, wherein the second valve 62 is used to connect or close the extraction system.

[0034] Optionally, the second connecting member 6 includes a second three-way pipe 61 and a second valve 62. One side of the second three-way pipe, specifically the side connected to the first three-way pipe, is provided with the second valve 62. One end of the second three-way pipe is connected to the connecting pipe through the second valve 63. In this case, the connecting pipe can be connected to the second collecting device. One side of the second three-way pipe 61 is completely closed and not connected to any device component. In this case, the second three-way pipe 61 has another side, which can be connected to one side of the first three-way pipe 52 in the first connecting member through the connecting pipe.

[0035] In one embodiment, the second three-way pipe 61 can be an acrylonitrile-butadiene-styrene copolymer plastic three-way pipe, a nylon three-way pipe or a five-toxic plastic three-way pipe.

[0036] In one embodiment, if Figure 1 As shown. The circulating water vacuum pump 2 at least includes a first vacuum port 21 and a second vacuum port 22; the bottom of the rotary evaporation device 1 is connected to one end of the sealing piston 51 connecting tube, the other end of the sealing piston connecting tube 51 is connected to one end of the first three-way tube 52, and the other end of the first three-way tube 52 is connected to the first collecting device 3; the rotary evaporation device 1 is also connected to the circulating water vacuum pump 2 through the first vacuum port 21; the circulating water vacuum pump 2 is connected to the second collecting device 4 through the second vacuum port 22; the second collecting device 4 is connected to one end of the second three-way tube 61, and the other side of the second three-way tube is connected to one end of the first three-way tube 52, wherein the other end of the first three-way tube 52 is connected to the first collecting device 3.

[0037] Optionally, the rotary evaporation device 1 is connected to the first vacuum port of the circulating water vacuum pump through a connecting pipe. The bottom of the rotary evaporation device 1 is connected to one end of the sealing piston 51 connecting pipe, and the other end of the sealing piston connecting pipe 51 is connected to one end of the first three-way pipe 52, and the other end of the first three-way pipe 52 is connected to the first collecting device 3. The third side of the first three-way pipe 52 is connected to one side of the second three-way pipe 61 through a connecting pipe, and can be connected to the inlet of the second three-way pipe 61. One side of the second three-way pipe 61 can be an outlet connected to the inlet of the second collecting device 4 through a connecting pipe, and the outlet of the second collecting device 4 is connected to the second vacuum port 22 of the circulating water vacuum pump 2. In traditional extraction devices, the second vacuum port is often idle. At this time, only two sides of the second three-way pipe are used, and a sealing measure is taken on the unused side, which can be a sealing cover to seal one side of the second three-way pipe. In this way, the entire collecting device system can achieve a closed connection.

[0038] Before use, check that the first three-way pipe 52, the first collecting device 3, the second three-way pipe 61, and the second collecting device 4 are all in a conducting state, that is, the first valve 53 in the first three-way pipe 52 and the second valve 62 in the second three-way pipe 61 are both open. And they are connected to the second vacuum port 22 of the circulating water vacuum pump 2, that is, connected to the idle vacuum port.

[0039] Turn on the power supply and cooling water in the usual order of use. The circulating water vacuum pump 2 starts to work, and both vacuum ports of the circulating water vacuum pump 2 can work, so that the entire rotary evaporator 1 is in a negative pressure state. The evaporating bottle in the rotary evaporator 1 is pre-loaded with the liquid to be concentrated, or the liquid to be concentrated can be introduced through the introduction tube of the connector of the rotary evaporator 1. Among them, the rotary evaporator 1 can be regarded as a four-way device. When the temperature and vacuum degree meet the requirements, evaporation and concentration begin. The evaporated and condensed liquid enters the first collecting device 3 and the second collecting device 4 through the rotary evaporator 1, or the connecting tube at the bottom of the four-way connector.

[0040] When the liquid in the first collecting device 1 needs to be recovered or the collected liquid is full, the first valve 53 of the first three-way pipe 52 can be turned to close the first collecting device 3, but still connected to the second three-way pipe 61. At this time, the piston of the first collecting device 3 can be unplugged to take out or pour out the evaporated liquid in the first collecting device 3. Then the empty first collecting device 3 is connected to the first three-way pipe 52. Then the knob is turned to close the channel between the rotary evaporator 1 or the bottom connecting pipe of the four-way connector and the first collecting device 52, and the second three-way pipe 62 is connected to the first collecting device 3, the air in the first collecting device 3 is extracted to form a vacuum, and then the knob of the first three-way pipe 52 is turned to connect the second collecting device 4 to the rotary evaporator 1 or the four-way connector and the second three-way pipe 61, so that the rotary evaporator 1 will not stop working due to taking the evaporated liquid. If the second collecting device 4 is full of liquid and needs to be taken out, the channel from the first three-way pipe 52 to the second three-way pipe 61 can be closed, which can be the second valve 62. At this time, the rotary evaporator is still working continuously. After taking out the liquid in the second collection package 4, first connect to complete the vacuuming of this part, and then connect to the first three-way pipe 52. In this way, the rotary evaporator can work uninterruptedly until the concentration work is completed.

[0041] The embodiment of the present application increases the original single-channel vacuuming to double-channel vacuuming, and changes the original power-off mode to a liquid-taking mode that can be operated without stopping the machine. This can significantly improve the condensation or evaporation efficiency and also save water and electricity.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
