Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical distillation technology, specifically a continuous distillation apparatus for pharmaceutical production. Background Technology

[0002] A continuous distillation unit mainly consists of a distillation column, a reboiler, and a condenser. The distillation column is the core component, containing trays (such as bubble cap trays, sieve trays, etc.) or packing materials (such as Pall rings, Raschig rings, etc.) to provide a space for gas-liquid contact. The reboiler heats the liquid at the bottom of the column, generating rising vapor, while the condenser cools the vapor at the top of the column, causing some of the vapor to condense and reflux. Separation is achieved by utilizing the different volatility of the components in the mixture. If some components are difficult to separate or are incompletely separated, they can be returned to the stripping section for further distillation. Based on the concentration, the appropriate concentration of the component can be selected through further separation. Alternatively, multiple temperature stages can be set to separate different components in multiple stages. This system can be used to separate multiple components in complex mixtures and can also be used to purify the active ingredients of pharmaceuticals.

[0003] Distillation units can achieve efficient separation by utilizing the different volatility of components in a mixture. However, since the distillation column trays inside the distillation column body require multiple bolts for locking, repeated tightening is necessary during assembly and disassembly, which is time-consuming and labor-intensive, resulting in low assembly and disassembly efficiency of the distillation column trays. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 5 In this embodiment of the present invention, a continuous distillation apparatus for pharmaceutical production includes a distillation column body 1, a base 2 at the bottom of the distillation column body 1, a condenser 3 at the top of the distillation column body 1 for condensation, and a replacement assembly 4 inside the distillation column body 1 for easy replacement. The replacement assembly 4 includes a fixed base 41 symmetrically and uniformly fixedly installed inside the distillation column body 1, a rotating disk 42 rotatably connected to the top of the fixed base 41, and an adjusting rod 43 fixedly installed at the top of the rotating disk 42. A distillation column plate 5 is snapped and fixedly fastened to the inner side of the fixed base 41, and through holes 9 are uniformly opened on the inner side of the distillation column plate 5. A snap-fit ​​groove 44 is uniformly opened around the outer periphery of the distillation column plate 5 to snap and fix it to the fixed base 41. A through groove 45 is uniformly opened around the inner side of the fixed base 41, and a snap-fit ​​block 47 adapted to the snap-fit ​​groove 44 is slidably connected inside the through groove 45. A reset spring 49 for resetting the snap-fit ​​block 47 is fixedly installed inside the through groove 45.

[0024] The above solution is adopted: the base 2 is equipped with a reboiler for heating the inside of the distillation column body 1. The top of the snap-fit ​​block 47 is an inclined surface that makes it easy to press and retract into the through groove 45. By replacing component 4, the problem of cumbersome disassembly of the distillation column plate 5 due to bolt fixing can be solved, and the portability of disassembling the distillation column plate 5 can be increased. By replacing component 4, the distillation column plate 5 can be installed quickly, reducing the cumbersomeness of rotating the threaded fixing one by one due to bolt fixing.

[0025] Reference Figures 1 to 5The through groove 45 has a snap-fit ​​groove 46 for the snap-fit ​​block 47 to slide, and the snap-fit ​​groove 46 is symmetrically opened inside the through groove 45. The snap-fit ​​block 47 has a snap-fit ​​slider 48 symmetrically fixed at both ends to be adapted to the snap-fit ​​groove 46. The top of the fixed base 41 is fixedly installed with a rotating ring 411, and the bottom of the rotating disk 42 has a rotating groove 413 that is rotatably connected to the rotating ring 411.

[0026] The above scheme is adopted: the snap-fit ​​groove 46 and the snap-fit ​​slider 48 facilitate the sliding guidance of the snap-fit ​​block 47 inside the through groove 45.

[0027] Reference Figures 1 to 5 One end of the rotating ring 411 is fixedly installed with a rotating ring block 416 that is rotatably connected to the rotating groove 413, and the rotating ring block 416 is symmetrically fixedly installed at both ends of the rotating ring 411. The top of the rotating ring 411 is evenly and symmetrically provided with slots 412. Inside the rotating groove 413 and directly above the slot 412, a fixing block 414 is fixedly installed. One end of the snap-fit ​​block 47 and directly above the reset spring 49 is fixedly installed with a fixing block 410. A connecting rope 415 is fixedly installed in the middle of the fixing block 414 and the fixing block 410.

[0028] Using the above scheme: the connecting rope 415 is a latex rope, which can return to its original shape after being stretched. When the connecting rope 415 is pulled, the locking slide groove 46 inside the through groove 45 and the locking sliders 48 at both ends of the locking block 47 will pull the locking block 47 to slide inside the through groove 45, thereby pulling the locking block 47 out of the locking groove 44 on the outer periphery of the distillation column tray 5.

[0029] Reference Figures 1 to 5 Inside the fixed base 41, there is a guide block 417 that is fixed to facilitate engagement with the distillation column tray 5, and the guide block 417 is evenly and fixedly installed around the inside of the fixed base 41.

[0030] By adopting the above scheme, the guide groove on the outer periphery of the distillation column tray 5 is aligned with the guide block 417 on the inner side of the fixed base 41, which will facilitate the installation of the distillation column tray 5 and the fixed base 41 by the staff and increase the installation speed.

[0031] Reference Figures 1 to 5 A liquid phase discharge pipe 7 is fixedly installed at one end of the distillation column body 1, a gas phase discharge pipe 6 is fixedly installed at one end of the distillation column body 1 and directly above the liquid phase discharge pipe 7, and a liquid phase input pipe 8 is fixedly installed at one end of the distillation column body 1.

[0032] The working principle of this utility model is as follows: When it is necessary to replace the distillation column tray 5 inside the distillation column body 1, the operator first holds the adjusting rod 43, and then the adjusting rod 43 drives the rotating disk 42 to rotate at the top of the fixed base 41. When the rotating disk 42 rotates, the fixing block 414 fixed at the bottom of the rotating groove 413 and the fixing block 410 at one end of the locking block 47 will pull the connecting rope 415 in the middle. When the connecting rope 415 is pulled, the locking slide groove 46 inside the through groove 45 and the locking sliders 48 at both ends of the locking block 47 will pull the locking block 47 to slide inside the through groove 45, thereby pulling the locking block 47 out of the locking groove 44 on the outer periphery of the distillation column tray 5. Then the distillation column tray 5 can be removed. By replacing component 4, the cumbersome disassembly of distillation column tray 5 caused by bolt fixing can be solved, increasing the portability of disassembly of distillation column tray 5. When installing distillation column tray 5, simply align the guide groove on the outer periphery of distillation column tray 5 with the guide block 417 on the inner side of the fixing base 41, and then press distillation column tray 5 directly. When pressing, the inclined surface at the top of the snap-fit ​​block 47 will retract the snap-fit ​​block 47 into the interior of the through groove 45. When the snap-fit ​​groove 44 and the snap-fit ​​block 47 are on the same horizontal plane, the return spring 49 inside the through groove 45 will automatically spring the snap-fit ​​block 47 into the snap-fit ​​groove 44 to complete the fixation. By replacing component 4, distillation column tray 5 can be installed quickly, reducing the cumbersome process of rotating and fixing each thread one by one due to bolt fixing.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
