[0023] The utility model provides a chromatographic mobile phase recycling device, comprising a base 101, an adjusting mechanism 102, a collecting mechanism 103 and a cooling mechanism 104, wherein the collecting mechanism 103 comprises two slide plates 105, a collecting box 106, a handle 107 and a first detector 108, the base 101 comprises a bottom plate 109 and four supporting legs 110, the adjusting mechanism 102 comprises an adjusting disk 111, a connecting shaft 112, a clamping ring 113 and a vertical plate 114, the cooling mechanism 104 comprises a condenser 115, a sealing cover 116, a second detector 117 and a flow control component 118, and the flow control component 118 comprises a flow tube 119, a flow valve 120 and two sealing rings 121.

[0024] According to the present specific embodiment, the cooling mechanism 104 is movably connected to the adjusting mechanism 102, the adjusting mechanism 102 is fixedly connected to the base 101, the first detector 108 is fixedly connected to one of the slides 105, both slides 105 are fixedly connected to the collection box 106, the handle 107 is fixedly connected to the collection box 106, the collection box 106 is slidably connected to the base 101, each of the supporting legs 110 is fixedly connected to the bottom plate 109, the vertical plate 114 is fixedly connected to the bottom plate 109, the connecting shaft 112 is rotatably connected to the vertical plate 114, the adjusting disk 111 is fixedly connected to the connecting shaft 112, the clamping ring 113 is fixedly connected to the connecting shaft 112, the flow control member 118 is fixedly connected to the cooling member 104, and the adjusting disk 111 is fixedly connected to the connecting shaft 112. The condenser tube 115 is fixedly connected, the second detector 117 is fixedly connected to the condenser tube 115, the sealing cover 116 is movably connected to the condenser tube 115, the condenser tube 115 is movably connected to the clamping ring 113, the two sealing rings 121 are fixedly connected to the circulation tube 119, and the circulation valve 120 is movably connected to the circulation tube 119. Through the cooperation of the collecting box 106 and the slide plate 105, the liquid is collected after the cooling mechanism 104 completely cools the liquid. Since the slide plate 105 and the base 101 are adapted to each other, the collecting box 106 will not slip. This design solves the problem in the prior art that it is inconvenient for the staff to install and collect the liquid after the condensed liquid of the condenser tube 115 is collected.

[0025] Among them, the cooling mechanism 104 is located on one side of the adjusting mechanism 102, the adjusting mechanism 102 is located above the base 101, the first detector 108 is located on one side of one of the slides 105, the two slides 105 are respectively located on both sides of the collecting box 106, the handle 107 is located on one side of the collecting box 106, and the collecting box 106 is located below the base 101. The setting of the slide 105 facilitates the movement of the collecting box 106. When the staff opens the circulation valve 120, the liquid in the condenser 115 flows out, passes through the bottom plate 109 and falls into the collecting box 106. After the collection is completed, it is also convenient for the staff to take it. After the transfer is completed, the collecting box 106 can be pushed under the bottom plate 109 through the two slides 105.

[0026] Secondly, each of the supporting legs 110 is respectively located on the circumferential side of the base plate 109, the vertical plate 114 is located above the base plate 109, the connecting shaft 112 is located on the inner wall of the vertical plate 114, the adjusting disk 111 is located at one end of the connecting shaft 112, and the clamping ring 113 is located at the other end of the clamping ring 113. The vertical plate 114 supports the connecting shaft 112 to facilitate the rotation of the connecting shaft 112 on the vertical plate 114. The staff adjusts the adjusting disk 111 to adjust the deflection angle of the clamping ring 113, and the condenser 115 will also follow the deflection. This method can mix the liquid in the condenser 115 and can also better facilitate the detection of the second detector 117. The content of liquid on the tube wall of the condenser 115 is different at different deflection angles, and the data obtained is also different.

[0027] At the same time, the flow control part 118 is located at the lower end of the condenser 115, the second detector 117 is located on one side of the condenser 115, the sealing cover 116 is located at the upper end of the condenser 115, the condenser 115 is located above the clamping ring 113, the two sealing rings 121 are both located on the inner wall of the circulation tube 119, and the circulation valve 120 is located on one side of the circulation tube 119. The two sealing rings 121 can seal the circulation valve 120 when the circulation valve 120 fails to open, thereby ensuring that the liquid in the condenser 115 will not spill out, and the sealing cover 116 can prevent foreign objects from entering the condenser 115 to avoid the mixing of impurities.

[0028] In this embodiment, by the cooperation between the collection box 106 and the slide plate 105, the liquid is collected after the cooling mechanism 104 completely cools the liquid. Since the slide plate 105 and the base 101 are adapted to each other, the collection box 106 will not slip. This design solves the problem in the prior art that it is inconvenient for the staff to install and collect the liquid after the condensation of the condenser 115 is collected. The setting of the slide plate 105 facilitates the movement of the collection box 106. When the staff opens the circulation valve 120, the liquid in the condenser 115 flows out, passes through the bottom plate 109 and falls into the collection box 106. After the collection is completed, it is also convenient for the staff to take it. After the transfer is completed, the collection box 106 is pushed under the bottom plate 109 through the two slide plates 105. That is, the vertical plate 114 supports the connecting shaft 112, so that the connecting shaft 112 can rotate on the vertical plate 114. The staff adjusts the adjusting disk 111 to adjust the deflection angle of the clamping ring 113, and the condenser 115 will also follow the deflection. This method can mix the liquid in the condenser 115 and can also better facilitate the detection of the second detector 117. The content of liquid on the tube wall of the condenser 115 is different at different deflection angles, and the data obtained is also different. The two sealing rings 121 can seal the circulation valve 120 when the circulation valve 120 fails to open, ensuring that the liquid in the condenser 115 will not spill out. The sealing cover 116 can prevent foreign objects from entering the condenser 115 to avoid the mixing of impurities.

The water suction pipe 202 is fixedly connected to the pump body 201 and is located on the other side of the pump body 201. The pump body 201 is fixedly connected to the base plate 109 and is located on one side of the base plate 109. By setting the pump body 201, the liquid to be cooled can be delivered to the condenser 115 through the delivery pipe 203. When condensation is not needed, the pump body 201 is stopped, thereby facilitating the staff to transfer the liquid to the condenser 115, and the experimental process is more convenient.

[0033] In this embodiment, by setting the pump body 201, the liquid to be cooled can be transported to the condenser 115 through the delivery pipe 203. When condensation is not needed, the pump body 201 is stopped, thereby facilitating the staff to transfer the liquid to the condenser 115, and the experimental process is more convenient.
