[0002] Aminohexanonitrile can be used as a raw material for organic synthesis, reacting with other compounds to produce organic compounds such as ethers and amides. In pharmaceutical manufacturing, it is used as an intermediate for the synthesis of antibiotics and anticancer drugs. In the production of materials based on aminohexanonitrile, reaction vessels are usually used for reaction production.

[0003] In the existing technology, the reaction vessels used in the production of materials based on aminohexanonitrile all have residual material on their inner walls after production. The traditional cleaning method is direct rinsing plus mechanical scraping. This method has the following problems: solvent residue during cleaning, cumbersome equipment disassembly, and the risk of toxic volatilization of aminohexanonitrile. Utility Model Content

[0004] The purpose of this invention is to provide a material residue cleaning device based on aminohexanonitrile production, which has the advantages of good cleaning effect. It uses ultrasonic and supercritical carbon dioxide flushing to effectively solve the problem of reagent residue without disassembling the equipment, and does not cause toxic volatilization. This solves the problems mentioned in the background art.

[0016] This invention, through the coordinated arrangement of the reaction mechanism and the processing mechanism, can effectively clean material residues produced based on aminohexanonitrile, and improves the cleaning effect and safety of the process. It utilizes supercritical carbon dioxide at a temperature of 31.1℃ and a pressure of 7.38MPa, which has strong solubility for organic nitrile substances, to quickly dissolve aminohexanonitrile residues. Furthermore, supercritical carbon dioxide easily evaporates through pressure reduction, leaving no secondary residues and avoiding solvent contamination of subsequent production.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a material residue cleaning device based on aminohexanonitrile production, including a vessel body 1:

[0025] The interior of the vessel body 1 is equipped with a reaction mechanism 2 for mixing materials, and a processing mechanism 3 for cleaning residual materials is provided on one side of the vessel body 1.

[0026] The reaction mechanism 2 includes a rotating component disposed inside the vessel body 1, and an ultrasonic generating component is also disposed on the inner side wall of the vessel body 1;

[0027] The processing mechanism 3 includes a storage component located on one side of the vessel body 1 and an extraction component adapted to the storage component. A heating component is located above the extraction component, and a spray component is located at the discharge end of the extraction component.

[0028] Preferred:

[0029] like Figure 2 As shown, the rotating assembly includes a lid 23 bolted to the top of the vessel body 1 and a motor 24 fixed to the top of the lid 23. The lid 23 can be used to seal the top of the vessel body 1 and also to support the installation of the motor 24. The output shaft of the motor 24 is keyed to a stirring rod 25. The motor 24 can complete the mixing process of the internal materials by driving the stirring rod 25 to rotate.

[0030] in:

[0031] like Figure 2 As shown, the ultrasonic generator assembly includes a partition 21 fixedly installed on the inner wall of the vessel body 1. An ultrasonic generator 22 is fixedly installed on the top of the partition 21. The partition 21 can separate the space inside the vessel body 1 and support the stirring rod 25. The stirring rod 25 is rotatably connected to the partition 21 through the partition. The ultrasonic generator 22 can perform high-frequency oscillation when cleaning is required to improve the cleaning effect.

[0032] It is worth noting that:

[0033] like Figure 3 As shown, the storage assembly includes a mounting bracket 31 fixedly installed on one side of the vessel body 1. A cryogenic storage tank 33 is fixedly installed on the top of the mounting bracket 31. The mounting bracket 31 can support and install the cryogenic storage tank 33 and the high-pressure pump 32 on its top. The cryogenic storage tank 33 can be used to store supercritical carbon dioxide.

[0034] further:

[0035] like Figure 3 As shown, the extraction assembly includes a high-pressure pump 32 fixedly installed on the top of the vessel body 1 and a connecting pipe 34 connected to one end of the high-pressure pump 32. The other end of the high-pressure pump 32 is connected to the low-temperature storage tank 33. The high-pressure pump 32 is used to extract and pressurize supercritical carbon dioxide for transportation through the connecting pipe 34.

[0036] Going a step further:

[0037] like Figure 4 As shown, the heating assembly includes an outer sleeve 35 fixedly installed on the outside of the connecting pipe 34. A heating tube 36 is fixedly installed inside the outer sleeve 35. The heating tube 36 surrounds the outside of the connecting pipe 34. The outer sleeve 35 facilitates the installation of the heating tube 36, which can directly heat the supercritical carbon dioxide passing through. The temperature can be controlled by an external silicon controlled rectifier temperature controller to ensure that the injected supercritical carbon dioxide is in a state of 31.1℃ and 7.38MPa.

[0038] at last:

[0039] like Figure 3 As shown, the spraying assembly includes a conveying pipe 37 connected to one end of the connecting pipe 34 and a coiled pipe 38 connected to the bottom end of the conveying pipe 37. A nozzle 39 is connected to the outside of the coiled pipe 38. There are two coiled pipes 38, and each coiled pipe 38 is connected to a nozzle 39. The spraying through the nozzle 39 can be used to flush away residual materials inside, so as to achieve the cleaning effect.

[0040] When cleaning residual materials, the heating tube 36 inside the outer sleeve 35 is activated in advance, and its temperature is controlled by an external silicon controlled rectifier temperature controller. Then, the high-pressure pump 32 is activated to extract supercritical carbon dioxide from the low-temperature storage tank 33. It is heated when passing through the connecting pipe 34 and pressurized by the high-pressure pump 32, so that it enters the delivery pipe 37 and the coiled pipe 38. Finally, supercritical carbon dioxide at a temperature of 31.1℃ and a pressure of 7.38MPa is sprayed out through the nozzle 39 to flush and clean the inner wall. At the same time, the ultrasonic generator 22 can be activated. When the ultrasonic generator 22 is working, the sticky residue can be peeled off by high-frequency vibration. Combined with the flushing of supercritical carbon dioxide, the cleaning efficiency is effectively improved compared with the traditional method, so as to complete the cleaning of residual materials.

[0041] The strong solubility of supercritical carbon dioxide in organic nitriles can rapidly dissolve aminohexanoic acid residues. Furthermore, supercritical carbon dioxide is easily volatilized by depressurization, leaving no secondary residues and avoiding solvent contamination in subsequent production. Combined with high-frequency oscillation to remove sticky residues, it achieves powerful cleaning performance.

[0042] In addition, the cleaned mixed fluids, such as supercritical carbon dioxide and dissolved aminohexanonitrile, enter an external gas-liquid separation device. After depressurization, the carbon dioxide becomes gaseous, and after drying and filtration, it is recompressed into a supercritical state for recycling. The separated aminohexanonitrile can be returned to the production system, which reduces waste emissions and raw material losses.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
