Description

Technical Field

[0001] This utility model relates to the field of plant extraction equipment technology, and in particular to a device for extracting active pharmaceutical ingredients from plants for aseptic inflammation. Background Technology

[0002] In the preparation of active ingredients in herbal medicines, the extraction tank is a crucial piece of equipment. By adding plant materials and extraction solvents into the extraction tank and utilizing the continuous stirring of a stirring mechanism, the dissolution efficiency of active ingredients can be significantly improved, and the production cycle shortened. In traditional extraction tanks, the stirring blades of the stirring mechanism are usually fixedly connected to the stirring rod by welding or complex bolt fastening methods. While this integrated or semi-permanent connection structure ensures structural stability during operation, it also introduces a problem that cannot be ignored.

[0003] When completing an extraction batch or when changing the extraction material, the inside of the extraction tank, especially every corner of the stirring blades, must be thoroughly cleaned and disinfected. Because plant residue is often highly viscous, it easily adheres to the joints, corners, and crevices of the stirring blades. With the aforementioned fixed connection structure, it is difficult for operators to easily detach the stirring blades from the stirring rod, making cleaning very difficult and impossible to guarantee thorough cleaning.

[0004] Incomplete cleaning can lead to serious consequences. Firstly, residual residue can cause cross-contamination between different batches, affecting the purity of the final active pharmaceutical ingredient. Secondly, the residue provides a breeding ground for microorganisms, posing a significant safety hazard to pharmaceutical ingredients intended for treating aseptic inflammation, directly impacting the safety and efficacy of the drug. Furthermore, the cumbersome cleaning process greatly extends equipment downtime for maintenance, reducing overall production efficiency.

[0005] Therefore, this invention proposes a device for extracting active pharmaceutical ingredients from plants that cause aseptic inflammation, in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a device for extracting active ingredients of plant aseptic inflammation, aiming to improve the problems of the existing technology where the structure of the stirring component is fixed, disassembly and cleaning are extremely inconvenient, and it is easy to cause material residue and cross-contamination.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides an extraction device for the active pharmaceutical ingredients of plant aseptic inflammation, comprising: an extraction tank, a motor, a stirring rod; and a quick-release mechanism;

[0008] The quick-release mechanism includes an openable and closable retaining ring, which is composed of a first retaining rod and a second retaining rod rotatably connected by a retaining post, and is closably fitted onto the outer wall of the stirring rod. A stirring blade is connected to the outer wall of the retaining ring.

[0009] Furthermore, the quick-release mechanism also includes a screw for locking or releasing the fixing ring. The screw is rotatably connected to the free end of the first fixing rod via a pin, and the screw is threadedly engaged with the free end of the second fixing rod. The outer wall of the screw is also fitted with a knob for operation.

[0010] Preferably, the extraction tank is internally divided with a filter plate and also includes a cleaning mechanism. The cleaning mechanism is disposed inside the extraction tank and located below the filter plate. The cleaning mechanism includes an underwater motor, a fixing frame, and a brush plate. The fixing frame is driven to rotate by the underwater motor, and the brush plate is slidably disposed within the fixing frame. The bristles of the brush plate abut against the lower surface of the filter plate.

[0011] Preferably, a spring is provided between the fixing frame and the brush plate, and the spring applies a spring force to the brush plate toward the filter plate;

[0012] Preferably, a limiting rod is fixedly connected to the brush plate, and the limiting rod slides through the fixed frame;

[0013] Preferably, the underwater motor is fixedly connected to the inner bottom of the extraction tank via a fixing plate;

[0014] Preferably, a turbine blade is also fixedly connected to the stirring rod;

[0015] Preferably, the stirring blade is hinged to the outer wall of the fixing ring;

[0016] Preferably, the side wall of the extraction tank is also connected to a discharge pipe.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a fixing ring composed of two openable rods and using a screw mechanism to lock or loosen the fixing ring, enables the quick assembly and disassembly of the stirring blade and stirring rod. This solves the problem in the prior art where the structure of the stirring component is fixed, disassembly and cleaning are extremely inconvenient, which easily leads to material residue and cross-contamination. It simplifies the cleaning and maintenance process, shortens downtime, improves production efficiency and ensures the purity and hygiene of the extract.

[0019] 2. This utility model solves the problem of easy clogging of the filter plate by medicinal residue during plant extraction, which requires manual cleaning and leads to low production efficiency, by setting a rotating brush plate driven by a motor below the filter plate in the extraction tank. This achieves online automatic cleaning of the filter plate, avoids clogging, and ensures continuous and stable extraction process.

[0020] 3. This utility model solves the problem of reduced cleaning effect and frequent replacement of brush bristles due to long-term wear and tear in automatic cleaning devices by setting a spring between the rotating brush plate and the fixed frame that drives its rotation. It utilizes the elastic force of the spring to continuously push the brush plate against the filter plate, thereby achieving automatic compensation for brush bristle wear, keeping the brush plate in close contact with the filter plate surface, extending the service life of the device and maintaining a stable cleaning effect.

[0028] 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.

[0029] Reference Figures 1-5 One embodiment of this utility model provides an extraction device for the active pharmaceutical ingredient of plant aseptic inflammation, including an extraction tank 1, a motor 5, and a stirring rod 601. The motor 5 is disposed outside the extraction tank 1, and the stirring rod 601 passes through the top of the extraction tank 1 and is connected to the output end of the motor 5. The device also includes a quick-release mechanism 6 disposed on the stirring rod 601.

[0030] Specifically, the quick-release mechanism 6 includes a fixing ring 603, which is detachably fitted onto the outer wall of the stirring rod 601. The fixing ring 603 is composed of a first fixing rod 604 and a second fixing rod 605, which are rotatably connected through one end of a fixing post 610. The outer wall of the fixing ring 603 is connected to a stirring blade 609. To achieve locking and unlocking of the fixing ring 603, the quick-release mechanism 6 also includes a screw 607, which is rotatably connected to the free end of the first fixing rod 604 away from the fixing post 610 through a pin 606. The screw 607 is threadedly fitted onto the free end of the second fixing rod 605 away from the fixing post 610. The outer wall of the screw 607 is fitted with a knob 608 for driving the screw 607 to rotate.

[0031] The cleaning mechanism 3 includes an underwater motor 301, a fixed frame 304, and a brush plate 302. The underwater motor 301 is fixedly connected to the bottom of the extraction tank 1 via a fixed plate 306 to provide power to the cleaning mechanism 3. The fixed frame 304 is connected to the output shaft of the underwater motor 301 and is driven to rotate by the underwater motor 301. The brush plate 302 is slidably disposed in the fixed frame 304, and the bristles of the brush plate 302 abut against the lower surface of the filter plate 4, thereby cleaning the filter plate 4 by rotation.

[0032] A spring 305 is also provided between the fixed frame 304 and the brush plate 302. The spring 305 applies a spring force to the brush plate 302 toward the filter plate 4 to compensate for the wear of the brush bristles of the brush plate 302 and ensure that the brush plate 302 is always in close contact with the filter plate 4. At the same time, a limiting rod 303 is fixedly connected to the brush plate 302. The limiting rod 303 slides through the fixed frame 304 to prevent the brush plate 302 from detaching during movement.

[0033] The stirring blade 609 is hinged to the outer wall of the fixed ring 603. In order to enhance the axial flow and mixing of the material in the extraction tank 1, a turbine blade 602 is also fixedly connected to the stirring rod 601. As another preferred embodiment, in order to facilitate the discharge of the extract after extraction, a discharge pipe 2 is also connected to the side wall of the extraction tank 1.

[0034] Working principle: When stirring the material inside the extraction tank 1, the drive motor 5 drives the stirring rod 601 to rotate. The stirring rod 601 drives the fixed ring 603 mounted on it to rotate synchronously. Since the stirring blade 609 is hinged to the outer wall of the fixed ring 603, the stirring blade 609 will expand outward due to centrifugal force during rotation, increasing the stirring range. It works in conjunction with the turbine blade 602 fixedly connected to the stirring rod 601 to achieve efficient mixing of the material. When it is necessary to disassemble the stirring blade 609 for cleaning, the operator turns... The knob 608 is turned, which drives the screw 607 to rotate. Since the screw 607 is rotatably connected to the first fixed rod 604 through the pin 606 and threadedly engaged with the second fixed rod 605, the rotation of the screw 607 will change the distance between the free ends of the first fixed rod 604 and the second fixed rod 605, thereby releasing the locking force on the stirring rod 601, so that the first fixed rod 604 and the second fixed rod 605 can rotate and open around the fixed column 610, thereby realizing the quick disassembly of the fixing ring 603 from the outer wall of the stirring rod 601;

[0035] When cleaning the filter plate 4, the cleaning mechanism 3 located at the bottom of the extraction tank 1 is activated. The underwater motor 301 drives the fixed frame 304 to rotate, and the fixed frame 304 drives the brush plate 302 inside it to rotate synchronously. During the rotation, the bristles of the brush plate 302 continuously brush the lower surface of the filter plate 4 to remove the attached drug residue. During this process, the spring 305 continuously applies a spring force towards the filter plate 4 to the brush plate 302 to automatically compensate for the wear of the bristles caused by long-term use, ensuring that the brush plate 302 is always in effective contact with the filter plate 4. The limiting rod 303 limits the sliding stroke of the brush plate 302 to prevent the brush plate 302 from falling out.
