DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] In order to make the technical problems, technical solutions and beneficial effects solved by this application clearer and more understandable, the following further details this application in combination with the drawings and embodiments.

[0022] Please refer to Figures 1 to 5 , a jacket for rapid cooling, including a jacket body 1 detachably sleeved outside the pipeline 100. One end of the jacket body 1 is provided with a water inlet 2, and the other end of the jacket body 1 is provided with a water outlet 3. A spiral groove 4 is arranged on the inner wall of the jacket body 1. The spiral groove 4 cooperates with the pipeline 100 to form a waterway 5 that communicates the water inlet 2 and the water outlet 3 and allows the cooling medium to flow through.
[0023] For the jacket for rapid cooling of this application, on the pipeline between the filter and the crystallization tank, a detachable jacket is provided, and a spiral groove is designed on the inner wall of the jacket body to form a waterway connecting the water inlet and the water outlet, thereby increasing the heat exchange area and prolonging the flow time of the cooling medium. Heat can be taken away more fully. Especially when processing crystallization liquid with a tonnage-level volume, the temperature of the solution can be quickly and effectively reduced, the decomposition and degradation of glutamine at high temperature can be reduced, thereby improving the purity and quality of glutamine, avoiding the generation of impurity pyroglutamic acid, and ensuring the stability and safety of the product.
[0024] Further, as a preferred implementation manner of this solution rather than a limitation, it further includes a locking mechanism 6. The jacket body 1 includes an upper jacket 11 and a lower jacket 12 hinged to the upper jacket 11. The locking mechanism 6 is used to close or open the upper jacket 11 and the lower jacket 12.
[0025] In this embodiment, by introducing the locking mechanism, flexible control of the closing or opening of the upper jacket and the lower jacket is realized. Such a design not only facilitates the installation and disassembly of the jacket body, but also can improve the tightness of the jacket. The locking mechanism can also adopt a spiral or wedge-shaped mechanical structure, enabling the operator to close or open the upper jacket and the lower jacket by rotating or pushing the locking mechanism.
[0026] Further, as a preferred implementation manner of this solution rather than a limitation, the locking mechanism 6 includes a first gasket 61 arranged on one side of the opening and closing of the upper jacket 11, a second gasket 62 arranged on one side of the opening and closing of the lower jacket 12, a screw 63 passing through the first gasket 61 and the second gasket 62, and a nut 64 arranged below the second gasket 62 and through which the screw 63 passes.
[0027] In this embodiment, through the settings of the first gasket and the second gasket, the sealing performance between the upper jacket and the lower jacket during closing is ensured, preventing the leakage of the cooling medium. The operator can control the clamping of the jacket on the pipeline by rotating the screw, thereby improving the production efficiency and product quality.
[0028] Furthermore, as a preferred implementation manner of this solution rather than a limitation, sealing glue 7 is provided at the edges of both the upper jacket 11 and the lower jacket 12, and the sealing glue 7 of the upper jacket 11 is in interference fit with the sealing glue 7 of the lower jacket 12.
[0029] In this embodiment, the sealing performance between the jackets is significantly improved, effectively preventing the leakage of the cooling medium and ensuring the safe and stable operation of the cooling system. At the same time, good sealing also helps to improve the heat exchange efficiency, extend the service life of the equipment, simplify the maintenance work, and reduce the maintenance cost.
[0030] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the water inlet 2 and the water outlet 3 protrude outward from the jacket body 1, and the water inlet 2 and the water outlet 3 are provided with threads.
[0031] In this embodiment, the design that the water inlet and the water outlet protrude outward from the jacket body and are provided with threads provides a convenient connection interface, making the connection with external pipelines or joints more direct and firm. This design enhances the sealing performance of the system, reduces the risk of cooling medium leakage. At the same time, the standardization of the threaded interface also improves the versatility of the system and the convenience of maintenance. In addition, the protruding design makes the entire cooling system more compact, saves space, and is convenient for the operator to perform daily maintenance and quick replacement.
[0032] Furthermore, as a preferred implementation manner of this solution rather than a limitation, it includes a plurality of jacket bodies 1 detachably sleeved outside the pipeline 100.
[0033] In this embodiment, a high degree of flexibility and adaptability is provided. The number of jackets can be increased or decreased according to the actual cooling requirements, and then the cooling area can be increased or decreased, thereby optimizing the cooling efficiency. At the same time, the detachable feature simplifies the installation, maintenance, and cleaning processes, reducing the maintenance cost. In addition, this modular design also facilitates the upgrade and expansion of the system, can adapt to changes in the production scale, improve the overall energy efficiency, and the convenience of operation.
[0034] Furthermore, as a preferred implementation manner of this solution rather than a limitation, the opening direction of the water inlet 2 is opposite to and parallel to the opening direction of the water outlet 3.
[0035] In this embodiment, it helps to maintain the continuity and uniformity of fluid flow, reduces the vortices and dead zones that may occur in fluid dynamics, thereby reducing the resistance and pressure loss of fluid flow, and improving the energy efficiency and operation convenience of the entire cooling system.
[0036] Further, as a preferred implementation manner rather than a limitation of this solution, the cooling medium enters from the water inlet 2 and spirally flows along the outer wall of the pipeline around the waterway 5 and then flows out from the water outlet 3 to cool the liquid in the pipeline.
[0037] The working principle of this embodiment is as follows:
[0038] A quick-cooling jacket of this application is provided on the pipeline between the filter and the crystallization tank. A detachable jacket is set, and spiral grooves are designed on the inner wall of the jacket body to form a waterway connecting the water inlet and the water outlet, thereby increasing the heat exchange area and prolonging the flow time of the cooling medium. Heat can be taken away more fully. Especially when dealing with crystallization liquid of tonnage volume, the temperature of the solution can be rapidly and effectively reduced, the decomposition and degradation of glutamine at high temperature can be reduced, thereby improving the purity and quality of glutamine, avoiding the generation of impurity pyroglutamic acid, and ensuring the stability and safety of the product.
[0039] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of this application is only limited to these descriptions.
