Description

Technical Field

[0001] This invention relates to the field of weight-loss drug technology, specifically to a device and method for preparing an extract of a traditional Chinese medicine composition for weight-loss drug preparation. Background Technology

[0002] In the preparation of weight-loss drugs, the herbal composition typically requires steps such as decoction, transportation, and filtration to obtain a clear extract. Among these, filtration is crucial for removing dregs, fibers, and insoluble particles, ensuring the quality of subsequent formulations. Currently, equipment used for filtering herbal extracts often employs an integrated filter structure, where one or more large-area continuous filter screens are installed within a primary filtration box or tank, allowing all the medicinal liquid to pass through this integrated filter for solid-liquid separation.

[0003] However, the integral filter screen has significant shortcomings in practical use. First, due to the uneven distribution of drug residue on the filter screen surface, a localized area (such as directly below the inlet or at the edge bend) often becomes clogged first. Existing integral filters cannot replace or clean this localized area individually; operators must remove the entire filter screen from the equipment for cleaning or replacement. This process not only requires a considerable downtime but also typically involves disassembling multiple components such as pressure plates, sealing strips, and support grids, making the operation cumbersome and maintenance inefficient. Second, the integral filter screen has a large area, resulting in high labor intensity during cleaning. Third, when multi-stage filtration or parallel processing of large quantities of drug solution is required, the integral filter screen structure cannot flexibly adapt to filtration channels with different particle size requirements. Once a localized blockage occurs, the entire filtration unit is forced to stop operating, severely impacting production continuity. Summary of the Invention

[0004] The problem to be solved by this invention is to provide a device and method for preparing extracts of traditional Chinese medicine compositions for weight loss drugs. When the filter screen of a certain channel is clogged, there is no need to disassemble the entire filter box. The filter screen of that channel can be cleaned or replaced by simply pulling out the corresponding mounting bracket from the outside. This makes maintenance convenient, does not interrupt the normal filtration of other channels, ensures continuous production, and allows for flexible replacement of filters with different mesh sizes to adapt to different drug filtration needs, thereby improving the applicability and maintenance efficiency of the equipment.

[0005] The technical solution provided by the present invention to solve the above problems is: a device for preparing extract of traditional Chinese medicine composition for preparing weight loss drugs, comprising a decoction component, a conveying component and a filtering component, wherein the conveying component is used to convey the decoction from the decoction component to the filtering component for filtration; The filtration assembly includes a filter box and several filter screen mechanisms.

Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0022] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0023] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0024] As shown in the accompanying drawings, a device for preparing extracts of traditional Chinese medicine composition for weight loss drugs includes a decoction component, a conveying component, and a filtering component. The conveying component is used to convey the liquid from the decoction component to the filtering component for filtration. The filter assembly includes a filter box 1 and several filter screen mechanisms. The filter box 1 has a cavity, which is divided into multiple filter channels 11 by several partitions 12. The filter screen mechanisms are disposed in the filter channels 11. Each filter screen mechanism includes a mounting frame 13 and a filter screen 14. The filter screen 14 is disposed on the mounting frame 13. The upper end of each filter channel 11 is provided with a mounting groove 6. The mounting frame 13 can be inserted into the filter channel 11 from the outside of the filter box 1 through the mounting groove 6.

[0025] The filtration assembly further includes an interception mechanism, which is used to intercept the liquid medicine in the filtration channel 11 when the filter screen mechanism in the filtration channel 11 is removed. Further, the interception mechanism includes an interception plate 8, a rotating shaft 9, and a stop block 10. The rotating shaft 9 is rotatably mounted on one side of the filtration channel 11 and is equipped with a torsion spring, which provides a rotation limit for the rotating shaft 9. The stop block 10 is located on the other side of the filtration channel 11, and the interception plate 8 is mounted on the rotating shaft 9. The upper end of the rotating shaft 9 extends through the filter box 1 and out of the filter box 1. A force application handle 7 is located at the upper end of the rotating shaft 9. It should be noted that an indicator is also provided on the force application handle to indicate whether the force application handle has rotated.

[0026] In this embodiment, the interception mechanism further includes a positioning component for positioning the interception plate 8. Specifically, the positioning component includes a positioning pin 16 and a float plate 15. The upper end of one side of the interception plate 8 is provided with a vertical movable groove and a horizontal receiving groove 17. The positioning pin 16 is L-shaped, with one end movably installed in the movable groove and the other end movably installed in the receiving groove 17. The upper end of the positioning pin 16 can extend out of the movable groove and engage with the positioning groove 18 at the top of the filter channel 11. The float plate 15 is fixedly connected to the positioning pin 16 at one end of the receiving groove 17.

[0027] In the preparation of weight-loss drugs, the herbal composition is decocted by the decoction assembly, and the decoction is then conveyed through the conveying assembly into multiple filtration channels 11 within the filter box 1, where it is filtered by the filter screens 14 in each filtration channel 11. During normal operation, the interceptor plate 8 is in an open state parallel to the filtration channels 11. The torsion spring on the rotating shaft 9 is twisted and stores energy, causing the float plate 15 to rise due to the buoyancy of the decoction, which causes the positioning pin to engage in the positioning groove, thus rotating and positioning the interceptor plate. When the filter screen 14 in a certain filtration channel 11 becomes severely clogged, the amount of decoction passing through that filter screen 14 decreases, causing the liquid level downstream of the filter screen 14 to gradually decrease. As the liquid level drops, the float plate 15 in that filtration channel 11 loses sufficient buoyancy and moves downwards under its own weight. When the float plate 15 moves downwards, it causes the positioning pin 16, which is fixedly connected to it, to move downwards as well, thereby disengaging the upper end of the positioning pin 16 from the positioning groove 18 at the top of the filtration channel 11. At this point, the interceptor plate 8, which was previously stuck by the positioning pin 16 and unable to move, is freed from its restraint. The torsion spring on the rotating shaft 9 immediately releases its accumulated elasticity, driving the rotating shaft 9 to rotate. This, in turn, causes the interceptor plate 8 to quickly rotate to a position perpendicular to the filter channel 11, completely blocking the filter channel 11. In this way, the upstream liquid cannot continue to flow to the downstream clogged filter screen 14, avoiding liquid overflow or excessive filtration pressure. The operator can then safely remove the mounting bracket 13 and filter screen 14 from the mounting slot 6 for cleaning or replacement. After the new filter screen mechanism is installed, the operator turns the force application handle 7. The force application handle 7 drives the rotating shaft 9 to rotate in the opposite direction against the elasticity of the torsion spring, causing the interceptor plate 8 to return from the vertical interception position to the open position parallel to the filter channel 11. As the liquid refills the filter channel 11, the float plate 15 rises under buoyancy, once again causing the positioning pin 16 to engage in the positioning slot 18, locking the interceptor plate 8 in the positioning state, and the filtration operation returns to normal.

[0028] In the above scheme, when the filter screen in a certain filtration channel becomes severely clogged, causing the downstream liquid level to drop, the float plate automatically moves downward under its own gravity, causing the positioning pin to disengage from the positioning groove. The torsion spring then drives the rotating shaft to rotate, causing the intercepting plate to rotate to a position perpendicular to the filtration channel, thereby automatically closing the channel. At this time, the unfiltered liquid upstream in the channel is blocked by the intercepting plate and will not continue to flow down. Therefore, the unfiltered liquid and the filtered liquid will not mix, completely avoiding cross-contamination and ensuring the stability of the liquid quality. At the same time, since the filtration assembly contains multiple independent filtration channels separated by partitions, the filters in the other channels can still work normally. The entire filtration process does not need to be interrupted, realizing uninterrupted continuous production and significantly improving the production efficiency of the equipment. When replacing or cleaning the clogged filter screen, the intercepting plate is in a locked state, and the operator can safely pull out the mounting bracket and filter screen from the mounting groove without any liquid leakage. Furthermore, since the upper end of the rotating shaft extends out of the filter box and is fixed with a force-applying handle, when the filter screen becomes clogged and triggers the rotation of the interceptor plate, the force-applying handle will undergo a significant change in angle or position. During routine inspections, operators do not need to open the equipment or rely on sensors; they can quickly locate the clogged channel simply by visually observing the posture of the indicator marks on each force-applying handle. This allows for targeted maintenance, reducing inspection costs and labor intensity. After replacing the filter screen, the operator only needs to manually rotate the force-applying handle to overcome the torsion spring force and reset the interceptor plate to the open position. At the same time, the solution refills the channel, the float plate rises, and it automatically locks the opening position again with the positioning pin. The entire process is intuitive and effortless.

[0029] It should be noted that the decocting assembly includes a decocting tank 5 and a frame 4, with the decocting tank 5 mounted on the frame 4. The conveying assembly includes a conveying pipe 3 and a conveying pump 2. One end of the conveying pipe 3 is connected to the decocting assembly, and the other end is connected to the filtering assembly. The conveying pump 2 is mounted on the conveying pipe 3.

The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
