Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine extraction, and specifically to a filtering device for decocting traditional Chinese medicine preparations. Background Art

[0002] Traditional Chinese medicinal materials refer to the original medicinal materials applied under the guidance of traditional medical skills for treating diseases. Traditional Chinese medicinal materials generally need to be decocted so that the useful components in the medicinal materials are dissolved into water to form a medicament. After decoction, filtration is also required to separate the medicament from the medicinal residues. The traditional method of decocting traditional Chinese medicine is to pour the prepared medicinal materials and clear water into a pot together, and then decoct the medicinal materials in the pot using an induction cooker or an open fire. After decoction is completed, the medicament is directly poured out, and the medicinal residues remain in the pot to achieve solid-liquid separation.

[0003] Decocting and filtering traditional Chinese medicinal materials in the traditional way can lead to insufficient extraction of the useful components in the medicinal materials. The main reasons are as follows: Firstly, since multiple traditional Chinese medicinal materials are poured into a container together during decoction, the medicinal materials will pile up, causing some of the medicinal materials to not come into full contact with hot water, and thus the useful components in the medicinal materials cannot be well extracted; Secondly, some medicinal materials have a large volume. During the decoction process, the components on the surface of the medicinal materials are more easily extracted, while the components inside the medicinal materials are difficult to be extracted. In addition, after the medicament is poured out, a large amount of water still remains in the medicinal residues, which is likely to cause waste. In view of this, we propose a filtering device for decocting traditional Chinese medicine preparations. Summary of the Invention

[0022] By means of the above technical solutions, the present invention provides a filtering device for decocting traditional Chinese medicine preparations. It has at least the following

[0023] Beneficial effects:

[0024] (1). For the filtering device for decocting traditional Chinese medicine preparations, by setting a pressure filtration mechanism, the medicinal materials and moisture in the filter cylinder can be stirred, so that the medicinal materials can fully contact with hot water, and thus the useful components in the medicinal materials can be better extracted. By setting an adjusting assembly, the pressure applying assembly can automatically operate with the rotation of the driving shaft, thereby intermittently squeezing the medicinal materials in the filter cylinder, so that the components in the medicinal materials can be fully extracted. By setting a separable filter cylinder and heating cylinder, the medicinal residues can be directly taken out from the medicinal liquid, and the excess moisture in the medicinal residues can be squeezed out by the pressure applying assembly during the taking-out process, avoiding the waste of the medicinal liquid.

[0025] (2) The filtering device used for decocting the traditional Chinese medicine preparation can separate the cam from the transmission plate by setting the adjusting component, so that the driving shaft cannot drive the pressing component to rotate. Thus, it can be avoided that the pressing component crushes the traditional Chinese medicine materials at the initial stage of decocting when the traditional Chinese medicine materials have not been completely softened, reducing the generation of crushed residues in the medicine.

[0026] (3) The filtering device used for decocting the traditional Chinese medicine preparation can scrape off the traditional Chinese medicine residues attached to the inner wall of the filtering cylinder through the operation of the scraping component. By setting the shaking component, it can promote the vibration of the filtering cylinder, thereby shaking off the medicinal materials attached to the inner wall of the filtering cylinder, the scraping plate and other structures, enabling the medicinal materials to enter the hot water for full decoction. At the same time, it can avoid residue sticking to the wall, facilitating the cleaning of the filtering cylinder.

[0027] (4) The filtering device used for decocting the traditional Chinese medicine preparation is provided with a notch on the filtering cylinder, which is convenient for pouring out the residues from the filtering cylinder. By setting a convex plate on the inner wall of the heating cylinder that is adapted to the notch, after the filtering cylinder is placed inside the heating cylinder, the filtering cylinder can be assembled into a complete cylindrical shape, thus facilitating the decoction and filtration of the traditional Chinese medicine.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1 - 8 , a technical solution provided by the present invention:

[0040] A filtering device for decocting traditional Chinese medicine preparations, including a heating cylinder 1, and the heating cylinder 1 can be placed on a heating device;

[0041] A filter cylinder 2 is placed inside the heating cylinder 1. A plurality of filter holes 21 are opened at the bottom end of the filter cylinder 2 for filtering traditional Chinese medicine residues;

[0042] A support frame 3 is fixedly installed at the top opening of the filter cylinder 2;

[0043] A pressure filtration mechanism 4 is arranged inside the filter cylinder 2 for improving the filtration efficiency and degree;

[0044] An anti-wall-hanging mechanism 5 is arranged inside the filter cylinder 2 for preventing the medicine residues from adhering to the inner wall of the filter cylinder 2;

[0045] Among them, the filter pressing mechanism 4 includes a drive shaft 41, which is rotatably installed on the inner wall of the filter cylinder 2. The top end of the drive shaft 41 is fixedly installed with a motor 44, and the motor 44 is fixedly installed on the support frame 3. A stirring frame 43 is fixedly installed on the drive shaft 41, and a material pressing component 42 is arranged on the drive shaft 41. An adjusting component 45 is arranged on the material pressing component 42. By setting the adjusting component 45, the material pressing component 42 can automatically operate as the drive shaft 41 rotates, thereby squeezing the medicinal residues in the filter cylinder 2, enabling the components in the medicinal residues to be fully separated, and at the same time avoiding waste caused by drugs remaining in the medicinal residues. Through the operation of the adjusting component 45, the material pressing component 42 can also be made not to operate as the drive shaft 41 rotates, thereby avoiding crushing the Chinese medicinal materials by the material pressing component 42 at the initial stage of decocting Chinese medicine when the Chinese medicinal materials have not been fully softened, reducing the generation of crushed residues;

[0046] The anti-wall-hanging mechanism 5 includes a scraping component 51, and a shaking component 52 is arranged on the scraping component 51. By setting the scraping component 51, the Chinese medicine attached to the inner wall of the filter cylinder 2 can be scraped off, and by the shaking component 52, the scraped medicinal materials can be shaken off.

[0047] During use, place the Chinese medicinal materials to be decocted in the filter cylinder 2, add an appropriate amount of water to the filter cylinder 2, and then place the filter cylinder 2 and the heating cylinder 1 together on a heating instrument for heating. During this period, start the motor 44. The output end of the motor 44 drives the drive shaft 41 to rotate, and the drive shaft 41 drives the stirring frame 43 to rotate to stir the medicinal materials, enabling the medicinal materials to come into full contact with the hot water and improving the efficiency of component separation in the medicinal materials. During this process, since the hot water will become less due to evaporation, some medicinal materials will adhere to the inner wall of the filter cylinder 2. The scraping component 51 scrapes off the Chinese medicine attached to the inner wall of the filter cylinder 2, and the shaking component 52 shakes off the scraped medicinal materials. When the medicinal materials are fully softened, start the adjusting component 45 so that the material pressing component 42 can automatically operate as the drive shaft 41 rotates, thereby squeezing the medicinal residues in the filter cylinder 2.

[0048] In some embodiments, a notch 22 is formed on the filter cylinder 2 to facilitate pouring out the medicinal residues from the filter cylinder 2. A convex plate 6 is fixedly installed on the inner wall of the heating cylinder 1. After the filter cylinder 2 is placed inside the heating cylinder 1, the surface of the convex plate 6 fits with the inner wall of the notch 22, thereby splicing the filter cylinder 2 into a complete cylinder body.

[0049] In some embodiments, a support platform 7 is fixedly installed on the bottom wall inside the heating cylinder 1. A plug rod 8 is fixedly installed at the top end of the support platform 7. A jack 23 is opened at the bottom end of the filter cylinder 2. The plug rod 8 is inserted into the jack 23. The number of the plug rods 8 is four, and the four plug rods 8 are circularly arrayed with the axis of the heating cylinder 1 as the center, which is used to position and limit the filter cylinder 2 and improve the stability of the filter cylinder 2. A handle 9 is fixedly installed at the top end of the support frame 3, which is convenient for taking out the filter cylinder 2 from the heating cylinder 1. A top cover 10 is placed at the top end of the heating cylinder 1, which is used to cover the opening at the top end of the filter cylinder 2 and reduce water loss.

[0050] In some embodiments, the pressing component 42 includes a driving bevel gear 426 which is fixedly installed on the driving shaft 41. A first bevel gear 425 is meshed with the driving bevel gear 426. A rotating cylinder 427 is fixedly installed on the first bevel gear 425. A cam 428 is arranged at one end of the rotating cylinder 427 away from the first bevel gear 425. A transmission plate 429 is in contact with the cam 428. The top of the transmission plate 429 is elastically connected to the bottom of the support frame 3 through a spring. By arranging the spring, after the protruding part of the cam 428 rotates away from the transmission plate 429, the transmission plate 429 can automatically reset under the elastic force of the spring. A sliding rod 423 is fixedly installed at the bottom of the transmission plate 429. A pressing plate 424 is fixedly installed at the bottom end of the sliding rod 423. When the driving shaft 41 rotates, it will synchronously drive the driving bevel gear 426 to rotate. The driving bevel gear 426 synchronously drives the first bevel gear 425 to rotate through meshing. The first bevel gear 425 synchronously drives the rotating cylinder 427 to rotate. The rotating cylinder 427 synchronously drives the cam 428 to rotate. The cam 428 presses the transmission plate 429 downward once every time it rotates one circle. The transmission plate 429 drives the pressing plate 424 to move downward through the sliding rod 423, so as to extrude the traditional Chinese medicine and make the components in the medicinal residues precipitate better. The pressing component 42 further includes a protective shell 421 which is fixedly installed on the support frame 3. A support plate 422 is fixedly installed on the protective shell 421. The sliding rod 423 is slidably installed on the inner wall of the support plate 422. The rotating cylinder 427 is rotatably installed on the inner wall of the protective shell 421.

[0051] In some embodiments, the adjusting assembly 45 includes a sliding plate 451 which is slidably mounted on the inner wall of the support frame 3. A movable rod 452 is rotatably mounted on the sliding plate 451. The surface of the movable rod 452 is fixedly connected to the inner wall of the cam 428. The movable rod 452 is inserted into the inside of the rotating cylinder 427. A convex portion is integrally formed on the surface of the movable rod 452. A groove is formed on the inner wall of the rotating cylinder 427. The surface of the convex portion is slidably connected to the inner wall of the groove, so that the movable rod 452 can move along the axis of the rotating cylinder 427 inside the rotating cylinder 427, and at the same time, the rotating cylinder 427 can drive the movable rod 452 to rotate synchronously, and further drive the cam 428 to rotate. A threaded rod 454 is threadedly connected to the inner wall of the sliding plate 451. A fixed seat 453 is rotatably connected to the surface of the threaded rod 454. The fixed seat 453 is fixedly mounted on the support frame 3. The number of the fixed seats 453 is two. The two fixed seats 453 are respectively located at both ends of the threaded rod 454, so as to improve the stability of the threaded rod 454. One end of the threaded rod 454 penetrates through the fixed seat 453 and is fixedly provided with a rotating handle 456 for manually controlling the rotation of the threaded rod 454. A limiting rod 455 is fixedly mounted on the support frame 3. The surface of the limiting rod 455 is slidably connected to the inner wall of the sliding plate 451. By providing the limiting rod 455, the circumferential movement of the sliding plate 451 can be restricted, so that the threaded rod 454 can drive the sliding plate 451 to move horizontally by rotation. The number of the limiting rods 455 is two. The two limiting rods 455 are symmetrically distributed with the center line of the sliding plate 451 as the axis of symmetry, so that the limiting effect is better.

[0052] In some embodiments, the scraping assembly 51 includes a fixing plate 517. The fixing plate 517 is fixedly installed at the bottom of the support frame 3. A transmission shaft 516 is rotatably installed on the inner wall of the fixing plate 517. A second bevel gear 519 is fixedly installed at one end of the transmission shaft 516. The second bevel gear 519 meshes with the driving bevel gear 426. A transmission gear 515 is fixedly installed at the other end of the transmission shaft 516. A gear ring 518 meshes with the transmission gear 515. A rotating sleeve 512 is fixedly installed on the gear ring 518. A connecting sleeve 513 is fixedly installed on the rotating sleeve 512. A scraping plate 514 is fixedly installed on the connecting sleeve 513. The surface of the scraping plate 514 contacts the inner wall of the filter cylinder 2. Through the meshing of the second bevel gear 519 and the driving bevel gear 426, the driving shaft 41 can synchronously drive the transmission shaft 516 to rotate. When the transmission shaft 516 rotates, it synchronously drives the transmission gear 515 to rotate. The transmission gear 515 drives the gear ring 518 to rotate around the axis of the filter cylinder 2 through meshing. The gear ring 518 drives the rotating sleeve 512, the connecting sleeve 513 and the scraping plate 514 to rotate synchronously, so that the scraping plate 514 scrapes off the residues attached to the inner wall of the filter cylinder 2. The scraping assembly 51 further includes a limiting ring 511. The limiting ring 511 is fixedly installed on the inner wall of the filter cylinder 2. The surface of the limiting ring 511 is rotatably connected to the inner wall of the rotating sleeve 512, so as to limit the rotating sleeve 512 and make the rotation of the rotating sleeve 512 more stable.

[0053] In some embodiments, the jittering assembly 52 includes a support rod 521. One end of the support rod 521 is fixedly connected to the inner wall of the connecting sleeve 513. A striking block 522 is slidably installed on the surface of the support rod 521. One end of the striking block 522 is elastically connected to the inner wall of the connecting sleeve 513 through a spring. The other end of the striking block 522 contacts the inner wall of the filter cylinder 2. By setting the spring, the striking block 522 has a certain telescopic ability, so that it can strike the inner wall of the filter cylinder 2 to promote the vibration of the filter cylinder 2 and thus shake off the residues. The jittering assembly 52 further includes a fixing ring 523. The fixing ring 523 is fixedly installed on the inner wall of the filter cylinder 2. A plurality of through holes 5231 are formed in the fixing ring 523. The plurality of through holes 5231 are circularly arranged around the axis of the filter cylinder 2. An arc surface is formed at one end of the striking block 522 close to the fixing ring 523, and the shape of the through hole 5231 is adapted to the shape of the striking block 522, so that when the striking block 522 rotates around the axis of the filter cylinder 2, it can automatically enter the through hole 5231 and automatically move out of the through hole 5231 during rotation, thus realizing the automatic striking of the filter cylinder 2.

[0054] When the filtering device for decocting the traditional Chinese medicine preparation of the present invention is in use, first place the traditional Chinese medicinal materials to be decocted in the filtering cylinder 2, and add an appropriate amount of clear water to the filtering cylinder 2. Then cover the top cover 10 on the heating cylinder 1 to reduce water evaporation. Subsequently, place the filtering cylinder 2 and the heating cylinder 1 together on a heating instrument for heating. During the heating process, start the motor 44. The output end of the motor 44 drives the driving shaft 41 to rotate. The driving shaft 41 drives the stirring frame 43 to rotate, stirring the medicinal materials so that the medicinal materials can be fully contacted with hot water, and improving the efficiency of the extraction of components in the medicinal materials. During the rotation of the driving shaft 41, it will synchronously drive the driving bevel gear 426 to rotate. The driving bevel gear 426 drives the second bevel gear 519 to rotate through meshing. The second bevel gear 519 synchronously drives the transmission shaft 516 to rotate. When the transmission shaft 516 rotates, it synchronously drives the transmission gear 515 to rotate. The transmission gear 515 drives the gear ring 518 to rotate around the axis of the filtering cylinder 2 through meshing. The gear ring 518 synchronously drives the rotating sleeve 512 to rotate. The rotating sleeve 512 drives the connecting sleeve 513 to rotate. The connecting sleeve 513 synchronously drives the scraping plate 514 to rotate around the axis of the filtering cylinder 2. During the rotation of the scraping plate 514, the residues attached to the inner wall of the filtering cylinder 2 are scraped off. During the rotation of the connecting sleeve 513, it will synchronously drive the striking block 522 to rotate on the surface of the fixed ring 523. When the striking block 522 rotates around the axis of the filtering cylinder 2, it can automatically enter the perforation 5231 and strike the inner wall of the filtering cylinder 2, promoting the vibration of the filtering cylinder 2, thereby shaking off the residues. After the medicinal materials are fully softened, start the adjusting assembly 45 so that the pressing assembly 42 can automatically operate with the rotation of the driving shaft 41. The specific method is as follows: rotate the turning handle 456, the turning handle 456 drives the threaded rod 454 to rotate. The threaded rod 454 drives the sliding plate 451 to move away from the rotating cylinder 427 through screw drive. The sliding plate 451 synchronously drives the movable rod 452 to move. The movable rod 452 drives the cam 428 to move above the transmission plate 429. In this way, during the rotation of the driving shaft 41, it can drive the first bevel gear 425 to rotate through the meshing of the driving bevel gear 426 and the first bevel gear 425. The first bevel gear 425 synchronously drives the rotating cylinder 427 to rotate. The rotating cylinder 427 drives the movable rod 452 to rotate synchronously through the cooperation of the convex part and the groove. The movable rod 452 drives the cam 428 to rotate. The cam 428 presses the transmission plate 429 downward once every rotation. The transmission plate 429 drives the pressing plate 424 to move downward through the sliding rod 423, squeezing the traditional Chinese medicine so that the components in the medicinal residues can be better extracted. After the filtering is completed, take out the filtering cylinder 2 from the heating cylinder 1 through the handle 9, thereby separating the medicinal residues from the medicinal agent. After the medicinal residues are completely separated from the medicinal agent, the pressing assembly 42 can squeeze out the excess water in the medicinal residues to avoid waste of the medicinal agent.
