The granule waste edges are removed, the cleanliness of the granules is improved, and the granules can be directly used in subsequent processing.

Description

Technical Field

[0001] This utility model relates to the field of solid dosage form processing technology, and in particular to a vacuum granulation machine for solid dosage form processing. Background Technology

[0002] Granulation is a crucial step in the production process of solid dosage forms, and its effectiveness directly affects the quality and performance of the final product. It has been used in the pharmaceutical, food, and chemical industries for a long time. However, with the continuous improvement of industry standards, its inherent drawbacks have become increasingly prominent. Among them, vacuum granulation machines are one of the keys to improving the processing efficiency of solid dosage forms by performing waste edge treatment on the granules.

[0003] In the vacuum granulation equipment for processing solid dosage form raw materials, when the granules are discharged from the equipment, they undergo a screening process to remove waste edges from the granules. At the same time as screening, the dust generated during the screening process is treated, and finally the screened granules are collected.

[0004] Existing vacuum granulation machines for solid dosage form processing leave residual waste edges on the surface of the processed granules, which affects subsequent processing of the granules. This process is time-consuming and labor-intensive, and also affects the efficiency of granule processing. Therefore, it lacks the function of removing waste edges from the granules. Hence, a vacuum granulation machine for solid dosage form processing is proposed. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention provides a vacuum granulation machine for solid dosage form processing. It has the following beneficial effects:

[0018] 1. The screening mechanism can screen the processed particles, removing excess material from the edges. After the processed particles are poured into the screening drum, the drum is rotated. Multiple limit wheels ensure the stability of the screening drum as it rotates. The processed particles are rotated within the drum, remaining at the bottom of the drum's inner cavity. Collisions between particles remove waste material. Because the screening drum is tilted, the guide plate then guides the particles out of the outer wall of the screen, effectively removing waste material and improving particle cleanliness for direct use in subsequent processing.

[0019] 2. The dust removal mechanism can handle the dust generated during the operation of the screening drum. During the operation of the screening drum, the fan is controlled to run. The fan, with the assistance of the pipeline and the dust suction hood, draws the dust generated in the inner cavity of the hood into the filter box. The dust is filtered through the filter plate, and the filtered gas is discharged from the exhaust hood. This has the function of removing dust, keeping the working environment clean, and preventing workers from inhaling dust into their lungs. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a vacuum granulator for solid dosage form processing, including a support frame 1, a granulation chamber 4 is provided on one side of the top of the support frame 1, a screening mechanism 2 is provided on one side of the granulation chamber 4, and a dust removal mechanism 3 adapted to the screening mechanism 2 is provided on the top of the support frame 1.

[0030] The screening mechanism 2 includes a support plate 201 symmetrically installed on the top of the support frame 1. A screening roller 204 is provided on the top of the support frame 1. Limiting rings 208 are evenly distributed and symmetrically sleeved on the outer surface of the screening roller 204. Side plates 207 are symmetrically installed on the top of the support plate 201. Limiting wheels 206 are movably installed on the opposite side of the two side plates 207 through bearing seats. External gear rings 209 are installed on the outer surface of the screening roller 204.

[0031] Specifically, the limiting wheel 206 is located on the opposite side of the two limiting rings 208 and is tumblingly connected to the outer surface of the screening drum 204. The output end of the granulation chamber 4 extends into the inner cavity of the screening drum 204. The top of the support frame 1 is provided with a leakage hole adapted to the screening drum 204. The screening drum 204 is located at the top of the leakage hole and is installed at a certain angle. When the screening drum 204 is driven to rotate, it can screen the particles output from the granulation chamber 4 and remove the raw materials remaining in the gaps after the particles are decompressed by screening, thereby improving the cleanliness of the processed particles and reducing subsequent processing steps.

[0032] Specifically, a motor 202 is mounted on the top of the support frame 1 via a mounting base. The output end of the motor 202 is connected to a gear 205 that is compatible with the external gear ring 209. A guide plate 203 that is compatible with the screening drum 204 is mounted on one side of the support frame 1 via a fixing block. The rotation of the gear 205 drives the external gear ring 209 to rotate, thereby driving the screening drum 204 to rotate and providing a certain power for the rotation of the screening drum 204.

[0033] Specifically, one end of the guide plate 203 is located at the bottom of the screening drum 204, and the gear 205 meshes with the outer gear ring 209. The outer gear ring 209 is located outside the limiting ring 208. Under the action of the guide plate 203, the particles with the waste edges removed are guided out of the screening drum 204, which facilitates the collection of particles on the outer wall of the screening drum.

[0034] Furthermore, the motor 202 is controlled to run, and the output end of the motor 202 drives the gear 205 to rotate. The gear 205 meshes with the outer gear ring 209, driving the outer gear ring 209 to rotate. With the assistance of multiple limit wheels 206, the outer gear ring 209 drives the screening drum 204 to rotate. At this time, the processed particles in the granulation chamber 4 are sent to the screening drum 204. Through the rotation of the screening drum 204 itself, the particles in the inner cavity rotate, and the particles collide with each other. The particles with the waste edges removed are discharged from the guide plate 203 and collected. The waste edges are collected downward through the support frame 1.

[0035] Example 2

[0036] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The dust removal mechanism 3 includes a cover 301 installed on the top of the support frame 1 and adapted to the granulation chamber 4. Mounting blocks 303 are evenly distributed and symmetrically installed on the top of the inner surface of the cover 301. A dust suction cover 304 is provided at the bottom of the mounting block 303. A filter box 305 is provided on the top of the cover 301. A filter plate 307 is movably inserted into the filter box 305.

[0037] Specifically, the dust removal mechanism 3 also includes a fan 308 installed on the top of the cover 301. The fan 308 is connected to the dust collection hood 304 and the filter box 305 through pipes. The dust collection hood 304 is located on the top of the screening drum 204. During the operation of the screening drum 204, a certain amount of dust will be generated. By controlling the operation of the fan 308, the fan 308 cooperates with the dust collection hood 304 through pipes to draw the dust generated in the inner cavity of the cover 301 into the filter box 305.

[0038] Specifically, the filter box 305 is connected to an exhaust hood 306 on one side, and a baffle 302 adapted to the screening roller 204 is provided on one side of the cover 301. The filter box 305 is provided with a top cover. Under the action of the baffle 302, the generated dust is blocked in the inner cavity of the cover 301, so that the dust suction hood 304 can completely absorb the dust. The top cover of the filter box 305 makes it easy to remove the residue in the filter box 305.

[0039] Furthermore, while the screening drum 204 is running, the fan 308 is controlled to run. The fan 308, through the cooperation of the pipe and the dust collection hood 304, generates a certain amount of dust during the screening process of the screening drum 204. Through the operation of the fan 308, the dust is drawn from the dust collection hood 304 towards the filter box 305. After the dust is drawn into the filter box 305, it is filtered through the filter plate 307. The filtered gas is then discharged from the exhaust hood 306.

[0040] Working principle: The device is connected to an external power controller using a wiring harness. The granulation chamber 4 is equipped with a vacuum granulation module, capable of processing solid dosage forms into the desired granules, similar to existing methods. Solid dosage forms are added from the top of the granulation chamber 4. After processing, the granules are sent from the output end on one side of the granulation chamber 4 to the screening drum 204. At this time, the control motor 202 operates, and its output end drives the gear 205 to rotate. The gear 205 meshes with the external gear ring 209, causing the external gear ring 209 to rotate. With the assistance of multiple limit wheels 206, the external gear ring 209 drives the screening drum 204 to rotate. At this point, the processed granules from the granulation chamber 4 are sent to the screening drum. In section 204, the rotation of the screening drum 204 itself causes the particles in the inner cavity to rotate, and the particles collide with each other. The particles with the waste edges removed are discharged from the guide plate 203 and collected. The waste edges are collected downwards through the support frame 1. While the screening drum 204 is running, the fan 308 is controlled to run. The fan 308, through the cooperation of the pipe and the dust collection hood 304, generates a certain amount of dust during the screening of the screening drum 204. Through the operation of the fan 308, the dust is drawn from the dust collection hood 304 towards the filter box 305. After the dust is drawn into the filter box 305, it is filtered through the filter plate 307. The filtered gas is discharged from the exhaust hood 306.
