Abstract
Description
Technical Field

[0002] A pharmaceutical raw material centrifugal separation and filtration device is a specialized piece of equipment used in pharmaceutical manufacturing processes to separate and purify mixtures. This device utilizes centrifugal force to separate substances of different densities, thereby achieving solid-liquid or liquid-liquid separation. In the pharmaceutical industry, it is commonly used to process complex mixtures such as fermentation broths and cell culture media to extract useful drug components or remove impurities.
[0003] In existing centrifugal separation and filtration devices, when centrifuging pharmaceutical raw materials, the filtration and centrifugation processes are usually completed within the same centrifuge drum. This leads to the gradual deposition and blockage of fine particles or highly viscous components in the raw materials during separation. This blockage not only reduces filtration efficiency and separation effect but may also increase equipment operating resistance, affecting equipment stability and service life. Furthermore, during long-term continuous operation, residues easily adhere to the inner wall of the centrifuge drum, further exacerbating the blockage problem, increasing cleaning difficulty, and reducing production efficiency.

[0016] This raw material centrifugal separation and filtration device, through the installation of separation components, enables continuous, high-efficiency filtration and centrifugation in the processing of pharmaceutical raw materials. The raw materials first undergo a filtration stage to initially remove impurities and large particles before falling into a centrifuge drum for high-speed centrifugal separation, thus achieving finer component purification. During filtration, the separation components apply vibration to the filter screen, enhancing filtration efficiency, accelerating raw material flow, and preventing filtration blockage caused by material accumulation. Simultaneously with centrifugation, the separation components also periodically clean the inner wall of the centrifuge drum through a dynamic cleaning motion, effectively removing attached residues and preventing problems such as filter clogging or poor discharge caused by impurity deposition. This improves the stability and ease of operation of the equipment, extends its service life, and is suitable for the continuous processing needs of high-viscosity or multi-component pharmaceutical raw materials.

[0026] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a raw material centrifugal separation and filtration device.
[0027] like Figures 1-8As shown, this utility model discloses a raw material centrifugal separation and filtration device, including a filter box 1.

The separation component 2 includes a first mounting box 21, wherein a first welding plate is fixedly connected to the top of the filter box 1, and one side of the first welding plate is fixedly connected to the outer surface of the first mounting box 21.

Two welding rods are fixedly connected to the outer surface of the protective box 25, and the end of the welding rod away from the protective box 25 is fixedly connected to the inner cavity of the filter box 1.
[0028] like Figures 2-8 As shown, a buffer plate 26 is fixedly connected to the inner cavity of the filter box 1, and the top of the buffer plate 26 is provided with an inclined surface. A centrifuge cylinder 27 is installed through the bottom of the inner cavity of the filter box 1. An L-shaped plate is fixedly connected to the bottom of the filter box 1, and the inner side of the L-shaped plate is rotatably connected to the outer surface of the centrifuge cylinder 27 through a bearing. The top and bottom ends of the centrifuge cylinder 27 extend to the outer side of the top of the buffer plate 26 and the outer side of the bottom of the filter box 1, respectively. The contact area between the centrifuge cylinder 27 and the buffer plate 26 and the filter box 1 is sealed, thereby facilitating the centrifugal separation of pharmaceutical raw materials through the centrifuge cylinder 27. The first motor 22... The output shaft is fixedly connected to a long rod 28, and the bottom end of the long rod 28 penetrates into the inner cavity of the centrifuge cylinder 27. One end of the long rod 28 penetrates into the outer side of the filter screen plate 24 and the protective box 25 in sequence. The long rod 28 and the filter screen plate 24 are movably connected to each other, so that the raw materials for pharmaceutical preparation can be filtered through the filter screen plate 24, which is sufficient to prepare for the next step of centrifugation. Several connecting discs 29 are fixedly connected to the outer surface of the long rod 28. A cleaning plate 210 that contacts the centrifuge cylinder 27 is fixedly connected to the outer surface of the connecting discs 29. The front and rear sides of the bottom of the filter screen plate 24 are fixedly connected to protruding plates 211.
[0029] like Figures 3-8As shown, connecting rods 212 are rotatably connected to both the front and rear sides of the inner cavity of the filter box 1, and the end of the connecting rod 212 away from the filter box 1 extends into the inner cavity of the protective box 25. The area where the connecting rod 212 penetrates and contacts the protective box 25 is sealed. Three meshing bevel gears 213 are fixedly connected to the outer surfaces of the connecting rod 212 and the long rod 28, respectively. The area where the long rod 28 penetrates and contacts the protective box 25 is rotatably connected by bearings. A top plate 214 that contacts the bottom outer surface of the convex plate 211 is fixedly connected to the outer surface of the connecting rod 212. A second mounting box is fixedly connected to the bottom of the filter box 1. 215. A second motor 216 is fixedly connected to the inner cavity of the second mounting box 215. Two gears 217 are fixedly connected to the output shaft of the second motor 216 and the outer surface of the centrifuge cylinder 27, respectively. The two gears 217 mesh with each other. Cylinders 218 are fixedly connected to the front and rear sides of the bottom of the filter box 1. A T-shaped rod 219 is fixedly connected to the output end of the cylinder 218. A sealing plate 220 connected to the bottom of the inner cavity of the centrifuge cylinder 27 is fixedly connected to the end of the T-shaped rod 219 away from the cylinder 218. A displacement sensor is installed on the outer surface of the sealing plate 220 to facilitate the identification of the position of the sealing plate 220.
[0030] Specifically, when the user pours the raw material to be centrifuged into the filter box 1, the first motor 22 is started. The first motor 22 drives the long rod 28 to rotate. At the same time, the long rod 28 drives the bevel gear 213, the connecting plate 29, and the cleaning plate 210 to rotate synchronously. The bevel gear 213 drives the connecting rod 212 and the top plate 214 to rotate. During the rotation of the top plate 214, it pushes the convex plate 211 and carries the filter screen 24 to stretch the spring damper 23, thereby generating vibration through the spring damper 23, and then filtering the raw material through the filter screen 24. At this time, the long rod 28 can also drive the cleaning plate 210 to clean the inside of the centrifuge cylinder 27 to prevent the raw material from clogging the centrifuge cylinder 27. When the filtered raw material falls into the centrifuge cylinder 27 for centrifugal separation, the second motor 216 is started. The second motor 216 drives the gear 217 to mesh and rotate. The gear 217 drives the centrifuge cylinder 27 to rotate. The centrifuge cylinder 27 uses the centrifugal force generated by the rotation to centrifuge and separate the raw material. After separation, the material is discharged through the discharge pipes on both sides of the bottom of the filter box 1. For impurities remaining after cleaning or centrifugation, the user can activate cylinder 218. Cylinder 218 pushes T-shaped rod 219 and sealing plate 220 downward, thereby causing sealing plate 220 to detach from the bottom of the inner cavity of centrifuge cylinder 27. At this time, the user can catch the impurities remaining after cleaning or centrifugation for easy use.
[0031] A raw material centrifugal separation and filtration device operates as follows: First, the user pours the pharmaceutical preparation raw materials into the filter box 1 for centrifugal separation. The pharmaceutical preparation raw materials are first filtered by the separation component 2. The filtered raw materials fall into the centrifuge cylinder 27 for centrifugal separation. During the separation and filtration process, the separation component 2 can also be used to vibrate and screen the raw materials during filtration, thereby speeding up the filtration process. During the separation process, the separation component 2 can also clean impurities inside the centrifuge cylinder 27 to avoid clogging of the centrifuge cylinder 27 and facilitate use.
