Description

Technical Field

[0001] The utility model relates to the technical field of molecular distillation test equipment, in particular to a heavy component cooling structure for a molecular distillation device. Background Art

[0002] Molecular distillation is a special liquid-liquid separation technology. The molecular distillation process is as follows: the material is added from the top of the evaporator, and is continuously and evenly distributed on the heating surface by the liquid distributor on the rotor. Then the scraper scrapes the liquid into a very thin, turbulent liquid film and propels it downward in a spiral. When the liquid mixture flows along the heating plate and is heated, the light and heavy components will escape from the liquid surface and enter the gas phase. Due to the different degrees of freedom of the light and heavy components, the molecules of different substances move different distances after escaping from the liquid surface. In this process, the light molecules escaping from the heating surface condense into liquid on the built-in condenser through the shortest route and almost without collision, and flow down the condenser tube and are discharged through the light molecule discharge pipe at the bottom of the evaporator.

[0003] Chinese utility model patent publication number: CN217661604U, discloses: a heavy component cooling device for a molecular distillation device, wherein the heavy component cooling device for a molecular distillation device allows a cooling component to cool down the heavy component with a higher temperature, thereby making the heavy component less likely to decompose due to excessively high temperature, thereby achieving the purpose of improving the purity of the heavy component. However, the heavy component cooling device for a molecular distillation device is designed with only one cooling structure, which easily leads to poor cooling effect during the cooling process, resulting in a long cooling time. In addition, the cooling tube is located inside the distillation equipment, which easily causes material to remain outside the spiral tube, making it inconvenient for subsequent use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a heavy component cooling structure for a molecular distillation device, which can effectively solve the problem that in the prior art, only one cooling structure is designed, which easily leads to poor cooling effect and long cooling time during the cooling process, and the cooling tube is located on the inner side of the distillation equipment, which easily leads to material residue on the outer side of the spiral tube, making it inconvenient for subsequent use.

[0005] The technical solution adopted by the utility model is: a heavy component cooling structure for a molecular distillation device, comprising a frame, a control box fixedly installed on the outer side of the frame, a mounting plate fixedly installed on the top of the frame, a sleeve provided at the bottom of the mounting plate, an inlet provided on the outer side of the top of the sleeve, an outlet provided on the outer side of the bottom of the sleeve, a support frame provided at the bottom of the sleeve, a cooling assembly and an equipment box provided on the outer side of the frame, and an air pump fixedly installed on the top of the inner side of the frame.

[0006] Preferably, the cooling assembly includes a refrigeration water tank and a cooling cover, a delivery pipe 1 is provided on the outside of the refrigeration water tank, a cooling pipe 1 is provided on the other end of the delivery pipe 1, a return pipe 1 is provided on the other end of the cooling pipe 1, the delivery pipe 1, cooling pipe 1 and return pipe 1 are connected, and the cross-section of the cooling pipe 1 is a "spiral" structure.

[0007] Through the above technical solution, the coolant is delivered to the cooling pipe 1 through the delivery pipe 1 by the built-in booster pump of the refrigeration water tank. The cooling pipe 1 is located in the interlayer 2 on the inner side of the cooling cover. Its cross-section is a "spiral" structure, which can increase the contact area with the sleeve. After the coolant absorbs heat, it returns to the refrigeration water tank through the return pipe 1 for cooling circulation, forming an independent cooling circuit, improving the reliability and stability of the cooling. The "spiral" structure of the cooling pipe 1 increases the contact area with the sleeve, improves the heat exchange efficiency, and can quickly and effectively reduce the temperature of the sleeve.

[0008] Preferably, a delivery pipe 2 is provided on the outside of the refrigeration water tank, a cooling pipe 2 is provided on the other end of the delivery pipe 2, a return pipe 2 is provided on the other end of the cooling pipe 2, the delivery pipe 2, cooling pipe 2 and return pipe 2 are connected, and the cross-section of the cooling pipe 2 is a "spiral" structure.

[0009] Through the above technical solution, the coolant is transported to the cooling pipe 2 through the refrigeration water tank through the delivery pipe 2. The cooling pipe 2 is located in the interlayer 1 on the inner side of the cooling cover, and the cross-section also has a "spiral" structure. After the coolant completes heat exchange in the cooling pipe 2, it flows back to the refrigeration water tank through the return pipe 2 to further enhance the cooling effect on the sleeve, and works together with the first cooling circuit to improve the cooling reliability.

[0010] Preferably, interlayer 1 and interlayer 2 are provided on the inner side of the cooling cover, the cooling pipe 1 is located in interlayer 2, and the cooling pipe 2 is located in interlayer 1.

[0011] Through the above technical solution, cooling pipe one is located in interlayer two, and cooling pipe two is located in interlayer one, which cool the sleeve together. Different cooling circuits can be selected according to actual usage.

[0012] Preferably, the refrigeration water tank has a built-in booster pump, a cooling fan is fixedly installed on the front side of the refrigeration water tank, and the cooling component is located on the outside of the sleeve.

[0013] Through the above technical solution, the design of the cooling fan can accelerate the heat dissipation of the refrigeration water tank, ensuring that the coolant is always at a low temperature, thereby improving the cooling effect and working efficiency of the cooling component.

[0014] Preferably, a positioning bolt is fixedly installed on the top of the mounting plate, and the positioning bolt passes through the mounting plate and extends to the inner side of the sleeve.

[0015] Through the above technical solution, when installing the sleeve, the positioning bolt can pass through the installation plate and extend to the inner side of the sleeve, which can fix the sleeve and facilitate the rapid installation of the sleeve.

[0016] Preferably, the cross section of the support frame is an "L"-shaped structure, and the support frame is provided with three identical ones, and the other end of the support frame is fixedly installed with the frame.

[0017] Through the above technical solution, one end of the three support frames is fixedly installed on the frame, and the other end supports the sleeve and other components, which can provide fixed support for the sleeve and avoid displacement.

[0018] Compared with the prior art, the present invention provides a heavy component cooling structure for a molecular distillation device, which has the following beneficial effects:

[0019] 1. The molecular distillation device uses a heavy component cooling structure, which forms a cooling circuit through the delivery pipe 1, cooling pipe 1 and reflux pipe 1, and cooperates with the delivery pipe 2, cooling pipe 2 and reflux pipe 2 to form a second cooling circuit. After the coolant completes heat exchange in the cooling pipe 2, it flows back to the refrigeration water tank through the reflux pipe 2 to further enhance the cooling effect on the casing. Working together with the first cooling circuit, it improves the cooling effect and avoids long cooling time.

[0020] 2. The molecular distillation device uses a heavy component cooling structure. The cooling pipe 1 is located in the interlayer 2, and the cooling pipe 2 is located in the interlayer 1, so as to cool the sleeve together. This avoids the cooling pipe being located on the inside of the distillation equipment, which easily causes the material to remain on the outside of the spiral tube and is inconvenient for subsequent use. In addition, the positioning bolts and support frame can be used to facilitate the quick installation of the sleeve to avoid subsequent displacement. BRIEF DESCRIPTION OF THE DRAWINGS
