Technical Field

[0001] This utility model relates to the field of purification technology, specifically to a device for purifying freeze-dried powder raw materials. Background Technology

[0002] Freeze-dried powders are widely used in the pharmaceutical, food, and cosmetic industries due to their high stability and ease of storage. As consumers increasingly focus on product quality, the market demand for high-purity, high-activity freeze-dried powder raw materials continues to grow. In the future, freeze-dried powder purification technology will develop towards intelligent, automated, and green methods, employing advanced sensors and control systems to improve purification efficiency and product quality.

[0003] Patent specification CN 206414861 U discloses a raw material purification device. It features a feed inlet with a pressure gauge on one side, a controller on one side of the main body, and a dissolving chamber inside the main body with a heating device at its bottom. The advantages of this invention are: it designs a compact, continuous, and highly efficient raw material purification device, integrating the dissolving, filtering, condensing, and centrifugal separation mechanisms within the main body, resulting in a compact, intelligently integrated design that saves factory floor space.

[0004] However, in implementing the relevant technology, the above-mentioned freeze-dried powder raw material purification device has the following problems: the device cannot fully mix the raw material with the solvent, and it cannot centrifuge the solution to separate the liquid. Therefore, we propose a freeze-dried powder raw material purification device. Utility Model Content

[0005] This invention proposes a freeze-dried powder raw material purification device, which solves the problems in related technologies such as insufficient mixing of raw materials and solvents, inability to remove impurities from raw materials, and limited purification accuracy.

[0006] The technical solution of the utility model is as follows:

[0007] A freeze-dried powder raw material purification device includes a main body, a drive motor, and an auger. A mounting frame is located at the top of the main body, and a drive motor is mounted on the outer wall of the bottom of the mounting frame. The drive shaft of the drive motor is connected to the auger. A feed funnel is located on the outer wall of the top of the main body, and a stirring chamber is located on the inner wall of the top of the main body. The bottom of the feed funnel extends into the stirring chamber. A liquid separation chamber is located below the stirring chamber. A filter plate is mounted on the inner wall of the stirring chamber, and a collection funnel is mounted at the bottom of the filter plate. A rotating shaft is connected to the bottom of the auger, and stirring rods are evenly spaced on the outer wall of the rotating shaft. The centrifuge cylinder is connected to the outer wall of the centrifuge chamber via a mounting block at one end of the rotating shaft, which extends through the outer wall of the filter plate. The centrifuge housing is fixedly mounted on the inner wall of the centrifuge chamber via the mounting plate. Centrifuge holes are evenly spaced on the outer wall of the centrifuge cylinder, and the interior of the centrifuge cylinder communicates with the inner wall of the centrifuge housing through the centrifuge holes. A sealing plate is provided at the bottom of the centrifuge chamber, and a discharge port is provided at the center of the sealing plate. A separator is provided at the bottom of the centrifuge cylinder, and a limit block is provided at the bottom of the separator. The bottom of the centrifuge cylinder is movably mounted on the outer wall of the sealing plate through the discharge port. A collection chamber is provided below the centrifuge chamber.

[0008] Preferably, a valve is provided on the side wall of the main body of the device, and one end of the valve is connected to the interior of the liquid separation chamber.

[0009] Preferably, the collecting chamber is connected to the interior of the centrifuge cylinder through the discharge port, and a sealing door is movably installed on the side wall of the collecting chamber via a bearing.

[0010] Preferably, the feed funnel has a conical structure, and the outer wall of the auger is in contact with the inner wall of the feed funnel.

[0011] Preferably, the side wall of the main body of the device is provided with a liquid inlet funnel, one end of which penetrates through the outer wall of the main body of the device and communicates with the interior of the stirring chamber.

[0012] Preferably, the outer wall of the centrifuge cylinder is provided with external threads, and the external threads are in contact with the inner wall of the centrifuge shell.

[0013] Preferably, the limiting block has a ring structure and is related to and fits the feeding port.

[0014] Preferably, the collecting funnel is in the shape of a cone funnel, and the bottom end of the collecting funnel extends into the interior of the centrifuge cylinder.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, the filtered mixed liquid enters the centrifuge cylinder through the collection funnel, centrifuge cylinder, and mounting block. Simultaneously, the centrifuge cylinder rotates via the shaft and mounting block, centrifuging the liquid and separating the liquid portion. The liquid and solid impurities are ejected through the centrifuge holes and pass between the outer wall of the centrifuge cylinder and the inner wall of the centrifuge casing. The liquid is then transported to the bottom of the centrifuge casing via a threaded connection to the inner wall of the centrifuge casing, flowing through a separator to the liquid separation chamber. The valve is opened to discharge the liquid. When centrifugation is complete, the drive motor is turned off, allowing the freeze-dried powder to enter the collection chamber through the discharge port on the outer wall of the sealing plate. The sealing door is opened to collect the purified freeze-dried powder raw material. This structure improves the purity of the raw material through centrifugal separation of wet and dry materials.

[0017] In this invention, a drive motor, a feeding funnel, and a stirring chamber are used to feed freeze-dried powder raw materials into the feeding funnel. The drive motor is started to rotate the auger, which, in conjunction with the inner wall of the feeding funnel, compresses the raw materials, grinding and pulverizing large solid pieces. Simultaneously, the auger pushes the raw materials into the stirring chamber located on the inner wall of the main body of the device. At the same time, solvent is injected into the stirring chamber through the liquid inlet funnel. The mounting frame drives the rotating shaft to rotate, which in turn drives the stirring blades to accelerate the thorough mixing of the solvent and the raw materials. Impurities are filtered out through a filter plate. This structure can grind and pulverize large solid pieces in the raw materials, facilitate mixing with solvent, and filter impurities.
