Description

Technical Field

[0001] This utility model relates to the field of drug purification technology, specifically a device for the crystallization, separation and purification of Western medicine. Background Technology

[0002] In the production of Western medicine, crystallization, separation, and purification are crucial steps that directly determine the purity and quality of the final product. The crystallization process aims to precipitate the pharmaceutical components from the solution in the form of regular crystals, while subsequent separation and purification operations remove impurities adhering to the crystal surface and other components from the mother liquor, thereby obtaining a high-purity pharmaceutical product.

[0003] Existing crystallization devices often employ a single-structure stirring paddle. When crystallizing concentrated Western medicine solutions, this often results in the upper layer of material being thoroughly stirred while the bottom layer remains stagnant and accumulates. This leads to an uneven crystallization system and disordered particle morphology, which not only increases the difficulty of subsequent separation but also affects the purity of the final product. Furthermore, some crystallized particles tend to adhere to the inner wall of the crystallization tank during the crystallization process, causing material loss. In the separation stage after crystallization, traditional filtration devices have low filtration efficiency. Due to the complex mixing state of the crystallized particles and the mother liquor, conventional static filtration methods are insufficient to quickly separate the crystallized particles from the waste liquid. Therefore, this invention provides a Western medicine crystallization separation and purification device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a Western medicine crystallization separation and purification device. It solves the problem that existing crystallization devices often use a single-structure stirring paddle, which easily leads to insufficient mixing of the upper layer of material while the bottom layer remains stagnant and accumulates during the crystallization of concentrated Western medicine liquid. This results in an uneven crystallization system and disordered particle morphology, increasing the difficulty of subsequent separation and affecting the purity of the final product. Furthermore, some crystallized particles tend to adhere to the inner wall of the crystallization tank during the crystallization process, causing material loss. In the post-crystallization separation stage, traditional filtration devices have low filtration efficiency. Due to the complex mixing state of the crystallized particles and the mother liquor, conventional static filtration methods are insufficient to quickly separate the crystallized particles from the waste liquid.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Western medicine crystallization separation and purification device, comprising a mounting bracket, wherein the mounting bracket is provided with a mounting mechanism for Western medicine crystallization separation and purification, the mounting mechanism comprising:

[0006] The stirring assembly includes a crystallization tank mounted on the upper end of a mounting bracket. Inside the crystallization tank, there is a stirring rod connected to a drive assembly. A scraper bracket is fixed to one side of the stirring rod, and an inclined flap is fixed to the lower end of the stirring rod.

[0007] The filter assembly includes a separation chamber located below the crystallization tank, with a support shaft inside the separation chamber and a filter frame connected to the outer wall of the support shaft via a push assembly.

[0008] Preferably, the driving assembly includes a first motor fixed to the upper end of the crystallization tank, the output end of the first motor is connected to a first driving rod, and the stirring rod is fixedly connected to the outer wall of the first driving rod.

[0009] Preferably, the upper end of the crystallization tank is provided with a feed inlet, and the lower end of the crystallization tank is threadedly connected with a discharge plug.

[0010] Preferably, the push assembly includes a second motor fixed to one side of the separation chamber, the output end of the second motor is connected to a second drive rod, a cam body is fixed to the outer wall of the second drive rod, the filter frame is rotatably connected to the outer wall of the support shaft, the cam body is located at the lower end face of the filter frame, the filter frame is designed to be inclined downward, a purification chamber is provided at the discharge end of the filter frame, and the purification chamber is fixedly connected to the mounting bracket.

[0011] Preferably, the lower end face of the filter frame is provided with a collection shell, and the collection shell is fixedly connected to the mounting bracket.

[0012] Preferably, the upper end of the purification chamber is provided with an opening and closing cover that rotates horizontally via a rotating shaft. The opening and closing cover is connected to the purification chamber by bolts. An annular tube is fixed to the inner wall of the purification chamber. Nozzles are evenly distributed inside the annular tube. An external water pipe for connecting washing liquid is fixed inside the annular tube.

[0013] Beneficial effects

[0014] This invention provides a device for the crystallization, separation, and purification of Western medicine. Compared with the prior art, it has the following advantages:

[0015] Firstly, after the concentrated Western medicine liquid of this invention is injected into the crystallization tank through the feed inlet, the first motor is started. The first motor drives the first drive rod to rotate, which in turn drives the stirring rod fixed on the outer wall of the first drive rod to rotate synchronously. When the stirring rod rotates, the scraper bracket on one side rotates along with the stirring rod against the inner wall of the crystallization tank, scraping off any crystal particles that may be attached to the tank wall. At the same time, the tilted flap at the lower end of the stirring rod rotates with the stirring rod, turning the material at the bottom of the crystallization tank upwards, mixing it thoroughly with the upper material. Simultaneously, the stirring promotes uniform crystallization of the material, forming a well-formed crystallization system, reducing the difficulty of subsequent separation. Moreover, the design of the scraper bracket can scrape off the crystal particles attached to the inner wall of the crystallization tank in real time, avoiding uneven crystallization caused by the accumulation of crystals on the tank wall, while reducing material loss. The tilted flap can effectively turn over the bottom material, solving the problem of "the upper material is fully stirred while the bottom material is left to accumulate" in conventional stirring, improving the overall stirring uniformity and promoting the formation of well-formed crystal particles.

[0016] Secondly, in this invention, the solution from the crystallization tank enters the separation chamber and falls onto the filter frame. The second motor is activated, driving the second drive rod to rotate, which in turn rotates the cam body. The cam body continuously pushes the filter frame, causing it to reciprocate on the support shaft. Waste liquid in the solution passes through the filter frame and is discharged from the bottom, falling into the collection shell for collection. Crystallized particles are trapped on the filter frame. Due to the downward-sloping design of the filter frame, the crystallized particles slide into the purification chamber under their own weight and the vibration of the filter frame, quickly separating the crystallized particles from the waste liquid in the solution, improving filtration efficiency. Simultaneously, the reciprocating rotation of the filter frame generates vibration, effectively preventing crystallized particles from clogging the pores of the filter frame and ensuring smooth filtration. Furthermore, the design of the annular pipe and evenly distributed nozzles allows the washing liquid to be sprayed evenly onto the crystallized particles, ensuring that all parts of the crystallized particles are thoroughly washed. Through efficient washing, impurities on the crystal surface are significantly removed, improving the purity and quality of the final pharmaceutical product. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a Western medicine crystallization separation and purification device, including a mounting bracket 1, on which a mounting mechanism for Western medicine crystallization separation and purification is provided, the mounting mechanism including:

[0024] The stirring assembly includes a crystallization tank 2 mounted on the upper end of the mounting bracket 1. Inside the crystallization tank 2, there is a stirring rod 203 connected by a drive assembly. A scraper bracket 204 is fixed on one side of the stirring rod 203, and an inclined flap 205 is fixed on the lower end of the stirring rod 203.

[0025] The filter assembly includes a separation chamber 4 located below the crystallization tank 2. A support shaft 401 is provided inside the separation chamber 4, and a filter frame 402 connected to the outer wall of the support shaft 401 via a push assembly is provided.

[0026] In a preferred embodiment, the driving assembly includes a first motor 201 fixed to the upper end of the crystallization tank 2, a first drive rod 202 connected to the output end of the first motor 201, a stirring rod 203 fixedly connected to the outer wall of the first drive rod 202, a feed inlet 3 provided at the upper end of the crystallization tank 2, and a discharge plug 301 threadedly connected to the lower end of the crystallization tank 2. The concentrated Western medicine liquid is injected into the crystallization tank 2 from the feed inlet 3 for stirring, and then sent into the separation chamber 4.

[0027] Specifically, after the concentrated Western medicine solution is injected into the crystallization tank 2 through the feed inlet 3, the first motor 201 is started. The first motor 201 drives the first drive rod 202 to rotate, which in turn drives the stirring rod 203 fixed on the outer wall of the first drive rod 202 to rotate synchronously. When the stirring rod 203 rotates, the scraper bracket 204 on one side rotates with the stirring rod 203 against the inner wall of the crystallization tank 2 to scrape off any crystal particles that may be attached to the tank wall. At the same time, the tilting flap 205 at the lower end of the stirring rod 203 rotates with the stirring rod 203 to turn the material at the bottom of the crystallization tank 2 upward and mix it thoroughly with the upper material. After the mixing is completed, the discharge plug 301 at the lower end of the crystallization tank 2 is unscrewed, and the crystal particles and mother liquor that have been mixed enter the separation chamber 4 below through the discharge port.

[0028] In a preferred embodiment, the push assembly includes a second motor 403 fixed to one side of the separation chamber 4. The output end of the second motor 403 is connected to a second drive rod 404. A cam body 405 is fixed to the outer wall of the second drive rod 404. The filter frame 402 is rotatably connected to the outer wall of the support shaft 401. The cam body 405 is located on the lower end face of the filter frame 402. The filter frame 402 is designed to be inclined downward. A purification chamber 5 is provided at the discharge end of the filter frame 402. The purification chamber 5 is fixedly connected to the mounting bracket 1. A collection shell 406 is provided on the lower end face of the filter frame 402. The collection shell 406 is fixedly connected to the mounting bracket 1. Crystallized particles are intercepted by the filter frame 402, and waste liquid is discharged from the bottom and collected by the collection shell 406. The crystallized particles are sent into the purification chamber 5.

[0029] Specifically, after the solution from the crystallization tank 2 enters the separation chamber 4, it falls onto the filter frame 402. The second motor 403 is started, which drives the second drive rod 404 to rotate, thereby causing the cam body 405 to rotate. The cam body 405 continuously pushes the filter frame 402, causing the filter frame 402 to reciprocate on the support shaft 401. The waste liquid in the solution passes through the filter frame 402 and is discharged from the bottom, falling into the collection shell 406 for collection. The crystal particles are trapped on the filter frame 402. Due to the downward tilt design of the filter frame 402, the crystal particles slide into the purification chamber 5 under the action of their own gravity and the vibration of the filter frame 402, which can quickly separate the crystal particles and waste liquid in the solution and improve the filtration efficiency.

[0030] In a preferred embodiment, the upper end of the purification chamber 5 is provided with an opening and closing cover 501 that rotates horizontally via a rotating shaft. The opening and closing cover 501 is connected to the purification chamber 5 by bolts. An annular tube 502 is fixed to the inner wall of the purification chamber 5. Nozzles 503 are evenly distributed inside the annular tube 502. An external water pipe 504 for receiving washing liquid is fixed inside the annular tube 502. When the crystallized particles enter the purification chamber 5, the opening and closing cover 501 is closed and fixed with bolts. The washing liquid is then connected to the annular tube 502 through the external water pipe 504. The washing liquid is evenly sprayed out from the nozzles 503 to wash the crystallized particles in the purification chamber 5 and remove impurities attached to the surface of the crystallized particles. After washing, the opening and closing cover 501 is opened and the purified crystals are taken out.

[0031] The first motor is model Y2-90S-4, and the second motor is model Y2-80M1-4.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, the concentrated Western medicine solution is injected into the crystallization tank 2 at the upper end of the mounting bracket 1 through the feed inlet 3. Then, the first motor 201 fixed at the upper end of the crystallization tank 2 is started. The first motor 201 drives the first drive rod 202 to rotate, which in turn drives the stirring rod 203 fixed on the outer wall of the first drive rod 202 to rotate synchronously. When the stirring rod 203 rotates, the scraper bracket 204 on one side of it rotates against the inner wall of the crystallization tank 2 to scrape off the crystal particles attached to the tank wall. At the same time, the tilting flap 205 at the lower end of the stirring rod 203 flips the material at the bottom of the crystallization tank 2 upward and mixes it thoroughly with the material at the upper layer. After the mixing is completed, the discharge plug 301 connected to the thread at the lower end of the crystallization tank 2 is unscrewed. The crystal particles and mother liquor that have been mixed enter the separation chamber 4 below the crystallization tank 2 through the discharge port.

[0034] After the material enters the separation chamber 4, it falls onto the filter frame 402 rotatably connected to the outer wall of the support shaft 401. The second motor 403, fixed to one side of the separation chamber 4, is activated. The second motor 403 drives the second drive rod 404 to rotate, which in turn causes the cam body 405 on the outer wall of the second drive rod 404 to rotate. The cam body 405 continuously pushes the filter frame 402, causing it to reciprocate on the support shaft 401. Waste liquid in the solution passes through the filter frame 402 and falls into the collection shell 406, which is fixed to the mounting bracket 1 at its lower end. Crystallized particles are trapped on the filter frame 402. The 402 is designed to slide downwards under its own weight and vibration into the purification chamber 5, which is fixed to the mounting bracket 1. After the crystallized particles enter the purification chamber 5, the opening and closing cover 501, which rotates horizontally via a rotating shaft, is closed and fixed with bolts. The washing liquid is connected to the annular pipe 502 fixed to the inner wall of the purification chamber 5 through the external water pipe 504 fixed on the annular pipe 502. The washing liquid is evenly sprayed out from the nozzles 503 evenly distributed inside the annular pipe 502 to wash the crystallized particles in the purification chamber 5 to remove impurities attached to the surface. After washing, the opening and closing cover 501 is opened and the purified crystals are taken out.
