[0002] A swing granulator for pharmaceutical intermediates is a device used in the pharmaceutical industry to process pharmaceutical intermediate powders into granules. The granulation technology of swing granulators is very common in the pharmaceutical industry because it can convert dry powder raw materials into granules with certain sizes and shapes through wet granulation. These granules usually have better fluidity and compressibility and are more suitable for subsequent pharmaceutical processes such as tabletting and capsule filling.

[0003] In the existing pharmaceutical production of pharmaceutical intermediates, it is usually carried out by pouring a wet mixture of pharmaceutical intermediate powders into a swing granulator for granulation. The current swing granulator can only perform granulation and has a relatively single function. When it is necessary to dry the granules, an additional drying device is required to dry the granules, which is rather troublesome to operate, resulting in low production efficiency of pharmaceutical production and high production costs due to the need to use different devices for pharmaceutical production.

[0004] Therefore, it is necessary to design a swing granulator for pharmaceutical intermediates that can granulate and dry a mixture of pharmaceutical intermediate powders, is simple to operate, realizes the integration of granulation and drying, reduces production costs, improves the production efficiency of pharmaceutical production, and improves the convenience of use.

[0021] The present utility model will be specifically described below with reference to the accompanying drawings.

[0022] A pharmaceutical intermediate rocking granulator, as Figures 1 - 5 shown, includes an outer shell 1, a servo motor 2, a crank 3, a rocking frame 4, a connecting rod 41, a screen 5, a drawer 6, and a drying mechanism 7. The servo motor 2 is connected to the inner side of the upper left part of the outer shell 1. A crank 3 is connected to the output shaft of the servo motor 2. The right part of the crank 3 is rotatably connected to a connecting rod 41. The right part of the connecting rod 41 is rotatably connected to a rocking frame 4. The rocking frame 4 is rotatably connected to the outer shell 1. The screen 5 is detachably connected to the inner side of the upper right part of the outer shell 1. The screen 5 is arc-shaped. The drawer 6 is slidably and detachably connected to the lower right part of the outer shell 1 for easy collection. A handle is provided on the right side of the drawer 6 for easy hand-holding and pulling of the drawer 6. A drying mechanism 7 for drying the granules is provided at the lower part of the outer shell 1.

[0023] As Figure 1 and Figure 4 shown, the drying mechanism 7 includes a fan 71, a heating tube 72, a partition board 73, a first torsion spring 74, and a first fixing block 75. The fan 71 is connected to the inner side of the lower left part of the outer shell 1. The heating tube 72 is connected to the middle of the outer shell 1. Two front and rear partition boards 73 are rotatably connected to the lower part of the outer shell 1. Two front and rear first fixing blocks 75 are connected to both the left and right sides of the lower part of the outer shell 1. The first fixing blocks 75 are rotatably connected to the partition boards 73 on the same side. A first torsion spring 74 is connected between each first fixing block 75 and the partition board 73 on the same side.

[0024] As Figure 1 and Figure 5As shown in the figure, it further includes a heat insulation mechanism 8. The heat insulation mechanism 8 includes a first heat insulation plate 81, a second heat insulation plate 82, a second torsion spring 83 and a second fixing block 84. The inner side of the right part of the housing 1 is connected with the first heat insulation plate 81. The left part of the housing 1 is rotatably connected with the second heat insulation plate 82. The second heat insulation plate 82 contacts the first heat insulation plate 81. Both the front and rear sides of the housing 1 are connected with the second fixing blocks 84. The second fixing blocks 84 are rotatably connected with the second heat insulation plate 82 respectively. A second torsion spring 83 is connected between the second fixing blocks 84 and the second heat insulation plate 82 respectively.

[0025] When swing granulation of pharmaceutical intermediates is required, this device can be used. Bring this device to the place where pharmaceutical production is needed, make the housing 1 contact the ground, and then add the wet pharmaceutical intermediate powder mixture into the housing 1, so that the powder mixture slides onto the swing frame 4. Then start the servo motor 2. Drive the crank 3 to rotate through the servo motor 2, and then drive the connecting rod 41 to rotate, so that the swing frame 4 swings, and then the powder mixture contacts the screen 5 for granulation. The formed granules fall on the first heat insulation plate 81 and the second heat insulation plate 82. When the accumulated granules reach a certain weight, the second heat insulation plate 82 rotates, and the second torsion spring 83 deforms, so that the granules slide onto the partition plate 73. The second torsion spring 83 rotates and restores, and the second heat insulation plate 82 rotates and resets. Thus, it can prevent hot air from entering the upper part of the housing 1 and prevent the hot air from drying the ungranulated powder mixture in the upper part, which affects granulation. Then start the fan 71 and the heating tube 72. Blow the hot air into the lower part of the housing 1 through the fan 71 to dry the granules. Thus, granulation and drying of the pharmaceutical intermediate powder mixture can be carried out. The operation is simple, realizing the integration of granulation and drying, reducing production costs, improving the production efficiency of pharmaceutical production, and improving the convenience of use. When a certain amount of material accumulates on the partition plate 73, the partition plate 73 rotates, and the first torsion spring 74 deforms, so that the dried granules fall into the drawer 6. The first torsion spring 74 rotates and restores, and the partition plate 73 rotates and resets. When granules of different sizes need to be made, remove the screen 5 by turning the bolt for replacement. The screen 5 is arc-shaped, so that the screen 5 can be replaced, which is convenient to meet the granulation requirements of different sizes of granules. After granulation is completed, turn off the servo motor 2 and the fan 71, and then pull out the drawer 6 through the handle, and then pour out the granules in the drawer 6 for collection.

[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
