Description
Technical Field
[0001] This invention relates to the field of amino acid derivatives, and in particular to a low-temperature reaction vessel for the preparation of amino acid derivatives. Background Technology
[0002] Amino acid derivatives are compounds generated from amino acids through chemical reactions. Their precursor is the amino acid. Amino acid derivatives possess various properties, such as good chemical stability, easy solubility, and antioxidant properties. Amino acid derivatives play an important role in the life activities of organisms. With the development of science and technology, their application scope continues to expand, making them important substances in fields such as biotechnology and medicine. The preparation process of amino acid derivatives usually involves a series of chemical reactions that can convert amino acids into derivatives with specific functions. The design, synthesis, and characterization of amino acid-derived ligands are based on the Lewis hard-soft acid-base theory. The basic requirement is to construct amino acid-derived bioPMOFs with specific binding sites with soft acid Hg2+ / boundary acid Pb2+. Based on literature and previous research, amino acid-derived ligands with potential "soft base / boundary base" coordination sites and easy assembly with metal ions are synthesized.
[0003] For example, patent number (CN214371296U) discloses a low-temperature cooling circulation device for the preparation of amino acid derivatives, including a support rod, a reaction vessel, a cooling circulation device body, a coolant pipe, an L-shaped collar, and a connecting sleeve.

The heat exchange contact area between the cooling structure and the main body of the equipment is small, which further affects the cooling and heat dissipation effect of the low-temperature reactor.

[0014] The beneficial effects of this utility model are:

This allows the cooling medium to cover most of the outer surface of the reactor body, expanding the heat exchange contact area. An annular partition plate divides the internal space of the connected shell, and connecting through-holes guide the flow of the cooling medium, enabling it to quickly and fully absorb the heat generated by the reactor body and discharge it through the external outlet pipe. This significantly improves the cooling and heat dissipation effect of the cryogenic reactor. The cooling medium is filtered through a filter element and filter screen, preventing dust and impurities from entering the connected shell and preventing scaling inside the shell, which could further affect the heat exchange effect. The filter structure is also easy to disassemble and assemble, ensuring the filtration effect of the filter box and extending the service life of the cryogenic reactor. Attached Figure Description

An annular partition plate 3 is fixedly installed on the surface of the reaction vessel body 1 inside the connecting shell 2. A connecting through hole 4 is opened on the inner side of the annular partition plate 3. An external liquid inlet pipe 5 is fixedly installed on the lower side of the surface of the connecting shell 2, and an external liquid outlet pipe 6 is fixedly installed on the upper side of the surface of the connecting shell 2. A filter box 7 is fixedly installed on the surface of the external liquid inlet pipe 5. A connecting slot 8 is opened inside the filter box 7. A locking frame 9 is provided inside the connecting slot 8. A filter element 10 is fixedly installed inside the locking frame 9. Filter screens 11 are fixedly installed on both the left and right sides of the filter element 10 inside the locking frame 9. The upper end of the locking frame 9 extends to the outside of the filter box 7. A sealing connection plate 12 is provided, with an installation groove 13 at its lower end. A metal sheet 14 is fixedly installed inside the installation groove 13. A connecting magnet 15 is fixedly installed inside the installation groove 13 at the upper end of the locking frame 9. Cooling medium is introduced into the interior of the connecting shell 2 through the external liquid inlet pipe 5. The flow direction of the cooling medium is guided by the annular partition plate 3 and the connecting through hole 4, so that the cooling medium can cover most of the outer surface area of the reactor body 1, expanding the heat exchange contact area and allowing the cooling medium to quickly and fully absorb the heat generated by the reactor body 1. The cooling medium is filtered by the filter element 10 and the filter screen 11 to prevent scaling inside the connecting shell 2. At the same time, the filter structure is easy to disassemble and assemble, thus ensuring the filtration effect of the filter box 7.
[0025] Please see Figures 1-3 In this embodiment, the reactor body 1 is fixedly connected to the connecting shell 2. A support foot 16 is fixedly installed at the lower end of the reactor body 1. The annular partition plates 3 are evenly distributed, and the connecting through holes 4 are staggered. The annular partition plates 3 are fixedly connected to the connecting shell 2. A support vertical rod 17 is fixedly installed on the inner surface of the connecting shell 2. The support vertical rod 17 is fixedly connected to the annular partition plates 3. Cooling medium is input into the interior of the connecting shell 2 through the external liquid inlet pipe 5 in conjunction with the liquid pump 19. The internal space of the connecting shell 2 is divided by the annular partition plates 3, and the flow direction of the cooling medium is guided by the connecting through holes 4. This allows the cooling medium to cover most of the outer surface area of the reactor body 1, expanding the heat exchange contact area. This allows the cooling medium to quickly and fully absorb the heat generated by the reactor body 1 and discharge it from the external liquid outlet pipe 6, which is beneficial to significantly improve the cooling and heat dissipation effect of the low-temperature reactor.
[0026] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, a check valve 18 is fixedly installed on the surface of the external liquid inlet pipe 5 on the side of the filter box 7, and a liquid pump 19 is fixedly installed on the surface of the external liquid inlet pipe 5 on the side of the check valve 18. The locking frame 9 is locked to the connecting slot 8, the sealing connecting plate 12 is detachably connected to the filter box 7, the locking frame 9 is locked to the mounting slot 13, and the connecting magnetic block 15 and the metal sheet 14 are mutually compatible. When the cooling medium is input, the cooling medium is filtered by the filter element 10 and the filter screen 11, thereby blocking dust and impurities in the medium from entering the connecting shell 2, preventing scaling inside the connecting shell 2, which would further affect the heat exchange effect. At the same time, the filter structure is easy to disassemble and assemble. The sealing connecting plate 12 can be disassembled periodically, and the locking frame 9 and the inner filter structure can be slid out to replace it, thereby ensuring the filtration effect of the filter box 7 and helping to extend the service life of the low-temperature reactor.
[0027] During operation, cooling medium is introduced into the connecting shell 2 through the external inlet pipe 5 and the liquid pump 19. The internal space of the connecting shell 2 is divided by the annular partition plate 3, and the flow direction of the cooling medium is guided by the connecting through hole 4. This allows the cooling medium to cover most of the outer surface area of the reactor body 1, expanding the heat exchange contact area. This enables the cooling medium to quickly and fully absorb the heat generated by the reactor body 1 and discharge it from the external outlet pipe 6. When the cooling medium is introduced, it is filtered by the filter element 10 and the filter screen 11 to prevent dust and impurities in the medium from entering the connecting shell 2, preventing scaling inside the connecting shell 2 and further affecting the heat exchange effect. At the same time, the filter structure is easy to disassemble and assemble. The sealing connecting plate 12 can be disassembled periodically, and the locking frame 9 and the inner filter structure can be slid out to replace it, thereby ensuring the filtration effect of the filter box 7.
[0028] Through the above steps, the cooling medium is introduced into the interior of the outer shell 2 through the external liquid inlet pipe 5. The flow direction of the cooling medium is guided by the annular partition plate 3 and the connecting through hole 4, so that the cooling medium can cover most of the outer surface area of the reactor body 1, expand the heat exchange contact area, and enable the cooling medium to quickly and fully absorb the heat generated by the reactor body 1. This solves the problem that the heat exchange contact area between the low-temperature reactor for amino acid derivative preparation and its cooling structure is small, which further affects the cooling and heat dissipation effect of the low-temperature reactor.
