[0002] Molecular distillation is a distillation method operated under high vacuum. At this time, the mean free path of vapor molecules is greater than the distance between the evaporation surface and the condensation surface. Therefore, the difference in evaporation rates of the components in the liquid can be used to separate the liquid mixture. When conducting molecular distillation experiments, a condenser is used. Laboratory condenser is a cooling device commonly used in laboratories, mainly used to condense vapor or gas and convert it into liquid.

[0003] The existing condenser has a drain port connected to a drain pipe, and the outlet end of the drain pipe is an open structure. When in use, a glass bottle is placed at the outlet end of the drain pipe to collect liquid. However, when the amount of liquid condensed by the condenser is large, when the glass bottle is replaced, some liquid will drip from the outlet end of the drain pipe, causing waste and loss, and also causing pollution to the test table. Utility Model Content

[0020] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0021] See also Figures 1 to 4 The present embodiment discloses a drain pipe structure of a molecular distillation experimental condensation system, the condensation system comprises a condenser body 1, the bottom end of the condenser body 1 is connected with a drain pipe 2, the outlet end of the drain pipe 2 is connected with a plug interface 3, the lower section of the outer side of the plug interface 3 is provided with a circle of anti-slip rubber strips 4, a separator ring 5 is fixedly arranged in the internal channel of the plug interface 3, a sealing disk 7 is arranged above the separator ring 5, a gap is left between the sealing disk 7 and the side wall of the internal channel of the plug interface 3, the center hole of the separator ring 5 is sealed by a sealing block 6 at the bottom of the sealing disk 7, the top of the sealing disk 7 is connected with a driving disk 9 through at least two connecting columns 8, and in the present embodiment, the top of the sealing disk 7 is connected by four connecting columns evenly distributed along the circumference. The column 8 is connected to the driving plate 9, and the four connecting columns 8 are respectively slidably matched with the top wall of the plug interface 3; the driving plate 9 is located above the plug interface 3 and slidably matched with the vertical section of the discharge pipe 2, and at least two push rods 10 are distributed on the periphery of the driving plate 9. In this embodiment, two push rods 10 are evenly distributed on the periphery of the driving plate 9, and the push rods 10 are inverted L-shaped rods. The main part of the push rod 10 extends downward along the periphery of the plug interface 3. The push rod 10 is located outside the anti-slip rubber strip 4. The bottom of the main part of the push rod 10 is provided with a resistance block 11, and a layer of flexible protective pad 12 is bonded to the bottom of the resistance block 11. The flexible protective pad 12 can be a rubber pad. The flexible protective pad 12 can be provided to protect the bottle mouth of the glass bottle. By moving the driving plate 9 up and down, the sealing plate 7 is driven to move up and down, and the central hole of the separation ring 5 is opened or sealed.

[0022] The outlet end of the drain pipe 2 extends vertically, and a fixed plate 14 is fixed on the outlet end of the drain pipe 2. The driving plate 9 is located below the fixed plate 14. The fixed plate 14 and the driving plate 9 are elastically connected by a reset spring 13. In a natural state, the reset spring 13 elastically presses the driving plate 9 downward, so that the sealing block 6 at the bottom of the sealing plate 7 seals the center hole of the separating ring 5.

[0023] The sealing block 6 at the bottom of the sealing disk 7 is in the shape of a truncated cone with a larger top and a smaller bottom, and the shape of the center hole of the separation ring 5 matches the shape of the sealing block 6. The top wall surface of the separation ring 5 is an inclined curved surface with the center tilted downward, which can easily guide the liquid to flow into the center hole of the separation ring 5. A circle of sealing rings 15 is also provided at the bottom of the sealing disk 7. The sealing rings 15 are located on the periphery of the sealing block 6. When the center hole of the separation ring 5 is sealed by the sealing block 6, the bottom wall of the sealing ring 15 fits with the top wall of the separation ring 5. The provision of the sealing ring 15 can increase the friction between the sealing disk 7 and the separation ring 5, thereby strengthening the seal.

[0024] In a natural state, under the elastic force of the return spring 13, the return spring 13 elastically presses the driving plate 9 downward, so that the sealing block 6 at the bottom of the sealing plate 7 seals the central hole of the separation ring 5, and the liquid condensed by the condenser does not drip downward.

[0025] When it is necessary to collect liquid, the mouth of the glass bottle is placed on the outside of the plug-in interface 3 from bottom to top. The stability of the connection between the glass bottle and the plug-in interface 3 can be increased by the anti-slip rubber strip 4. When the top of the glass bottle conflicts with the flexible protective pad 12 at the bottom of the push rod 10, the conflict block 11 and the push rod 10 can be pushed upward to move, and the driving disk 9 at the top of the two push rods 10 is lifted upward. The reset spring 13 is compressed, and the driving disk 9 drives the sealing disk 7 to move upward through the connecting column 8, so that the sealing block 6 at the bottom of the sealing disk 7 is away from the center hole of the separation ring 5, and the center hole of the separation ring 5 is opened. At this time, the liquid inside the condenser body 1 will enter the glass bottle through the drain pipe 2 and the plug-in interface 3 to realize the collection of liquid. When the collection is completed, take down the glass bottle, and the elastic force of the reset spring 13 pushes the driving disk 9 to automatically reset, thereby realizing the automatic reset of the sealing disk 7, avoiding liquid dripping and causing loss and contamination of the table.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
