Description

Technical Field

[0001] The present invention relates to the technical field of filtering equipment, and particularly to a filtering device for traditional Chinese medicine processing. Background Art

[0002] Traditional Chinese medicine refers to drugs prepared through processes such as collection, processing, and preparation under the guidance of traditional Chinese medicine theory, which has the functions of preventing and treating diseases, as well as rehabilitation and health care. It mainly comes from plant drugs, animal drugs, and mineral drugs, among which plant drugs account for the vast majority.

[0003] In the process of traditional Chinese medicine processing, multiple key steps are usually involved, such as decocting, which uses water or other solvents to promote the full dissolution of the active ingredients in the medicinal materials under appropriate temperature and time conditions; and filtering and other steps. Among them, the filtering step plays a crucial role in traditional Chinese medicine processing. It can separate the medicinal residues from the effective medicinal liquid after decocting, so as to obtain pure medicinal liquid for further preparation.

[0004] When filtering traditional Chinese medicine, filtering equipment is required. In related technologies, for example, Chinese Patent CN217247131U discloses a traditional Chinese medicine filtering device. When this traditional Chinese medicine filtering device is used, first, the cover is opened, and the traditional Chinese medicine liquid is poured into the filtering tank body. After passing through the filter membrane and filter net, the traditional Chinese medicine liquid flows into the filtering tank body, and the filtered traditional Chinese medicine liquid can be discharged through the drain pipe.

[0005] However, the above traditional Chinese medicine filtering device also has some problems in actual use: after filtering is completed, there is often still a large amount of medicinal liquid remaining in the medicinal residues. This part of the residual medicinal liquid contains a large amount of active ingredients and has not been fully extracted and utilized, resulting in waste of resources. Summary of the Invention

[0006] Based on this, it is necessary to provide a filtering device for traditional Chinese medicine processing to address the serious problem of resource waste in the current traditional Chinese medicine filtering process.

[0007] The above object is achieved through the following technical solutions:

[0008] A filtering device for traditional Chinese medicine processing, the filtering device for traditional Chinese medicine processing includes:

[0009] A pot body;

[0010] A frame inserted into the pot body;

[0011] An annular filter screen inserted into the frame;

[0012] Two blocking parts are respectively blocked and fixedly arranged at both ends of the annular filter screen. One of the blocking parts is fixedly arranged on the frame, and the other blocking part is arranged on the frame and can rotate around the axis of the annular filter screen to drive the annular filter screen to undergo torsional deformation.

[0013] Further, the blocking part is a hemispherical elastic structure; the annular filter screen has corresponding first and second states before and after deformation. When in the first state, both of the two blocking parts bulge outwards, and when in the second state, both of the two blocking parts bulge inwards.

[0014] Further, the material of the blocking part includes silicone rubber.

[0015] Further, the filtering device for traditional Chinese medicine processing further includes a plurality of torsion rods. The torsion rods extend along the axis direction of the annular filter screen and are fixedly arranged on the outer peripheral wall of the annular filter screen. The plurality of torsion rods are arranged circumferentially, and both ends of the torsion rods are respectively ball-jointed on the two blocking parts.

[0016] Further, a rotation hole is arranged on the rotatable blocking part. The filtering device for traditional Chinese medicine processing further includes a rotating part. The rotating part can be clamped at the rotation hole and can rotate around the axis of the annular filter screen.

[0017] Further, the rotation hole is a cross-shaped structure; the rotating part is a rod-shaped structure and the cross-sectional shape is cross-shaped.

[0018] Further, the filtering device for traditional Chinese medicine processing further includes a bracket and a hook. The bracket is arranged on the pot body; the hook is hooked on the bracket and the frame at the same time.

[0019] Further, the number of the hooks is multiple and they are arranged circumferentially.

[0020] Further, a plurality of filter holes are arranged on the blocking part.

[0021] Further, a handle is arranged on the pot body.

[0022] The beneficial effects of the present invention are:

[0023] During the filtering process of the filtering device for traditional Chinese medicine processing provided by the present invention, first drive the rotatable blocking part to rotate around the axis of the annular filter screen, so that the annular filter screen undergoes torsional deformation with the other blocking part as a reference to extrude the medicinal residues, so that the remaining medicinal liquid in the medicinal residues can be extruded and flow into the pot body, thereby realizing the recovery of the medicinal liquid and reducing resource waste.

[0024] Furthermore, by setting both blocking parts as hemispherical elastic structures, before the annular filter screen deforms, both blocking parts bulge outwards, making the volume of the chamber formed by the annular filter screen and the two blocking parts relatively large, so that more medicinal residues can be placed, which is beneficial to improving the filtration efficiency; after the annular filter screen deforms, both blocking parts bulge inwards. On the one hand, it can turn the medicinal residues radially, which is beneficial to improving the uniformity of the distribution of the medicinal residues, and at the same time can make the extrusion effect in each area consistent. On the other hand, it can increase the extrusion force and improve the filtration effect. At the same time, both blocking parts tend to bulge inwards under the action of elasticity, so that the annular filter screen can be continuously pressed, which is beneficial to improving the extrusion effect on the medicinal residues.

[0025] Furthermore, by setting the torsion rod, when the rotatable blocking part rotates, the torsion rod moves synchronously and drives the annular filter screen to undergo torsional deformation. Supported by the torsion rod, on the one hand, the annular filter screen can maintain good shape stability during the deformation process, without local excessive deformation or wrinkle accumulation, ensuring uniform and stable extrusion effect on the medicinal residues. On the other hand, it can increase the extrusion force on the medicinal residues, which is beneficial to improving the recovery efficiency of the medicinal liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Such as Figures 1 to 9As shown in the figure, the filtering device for traditional Chinese medicine processing provided by the embodiment of the present invention is used for filtering liquid medicine, and is set to include a pot body 1, a frame 2, an annular filter screen 3 and two blocking parts 4. The frame 2 is inserted into the pot body 1; the annular filter screen 3 is inserted into the frame 2; the two blocking parts 4 respectively block and are fixedly arranged at both ends of the annular filter screen 3, one of the blocking parts 4 is fixedly arranged on the frame 2, and the other blocking part 4 is arranged on the frame 2 and can rotate around the axis of the annular filter screen 3 to drive the annular filter screen 3 to be torsionally deformed.

[0041] Specifically in this embodiment, the pot body 1 is set as a cylindrical structure with an open top; taking the case where the annular filter screen 3 is vertically placed as an example, for the convenience of description, the blocking part 4 located at the bottom of the annular filter screen 3 is named the first blocking part, and the blocking part 4 located at the top of the annular filter screen 3 is named the second blocking part. The first blocking part is set as a rigid disc-shaped structure and is coaxially arranged with the annular filter screen 3 to ensure that the bottom of the annular filter screen 3 can be supported. The second blocking part is set as a rigid disc-shaped structure and is coaxially arranged with the annular filter screen 3 to ensure that it can not only support the top of the annular filter screen 3 but also drive the annular filter screen 3 to rotate.

[0042] The frame 2 is set to have a first base ring 201 and a second base ring 202. The first base ring 201 and the second base ring 202 are both horizontal and coaxially arranged. The first base ring 201 is located below the second base ring 202. A plurality of connecting rods 203 are vertically arranged on the top of the first base ring 201. The plurality of connecting rods 203 are arranged circumferentially. A plurality of connecting pipes 204 are vertically arranged on the bottom of the second base ring 202. The plurality of connecting pipes 204 are arranged circumferentially and are fixedly sleeved on the connecting rods 203 during installation.

[0043] To facilitate the installation of the first blocking part, a first annular groove is provided on the top of the first base ring 201. The first annular groove penetrates the inner peripheral wall of the first base ring 201 at the same time. The first blocking part is coaxially inserted into the first annular groove during installation. The filtering device for traditional Chinese medicine processing is also set to include at least two first pressing pieces 8. The first pressing pieces 8 are arranged on the top of the first base ring 201. The plurality of first pressing pieces 8 are arranged circumferentially on the first base ring 201 and jointly press against the top of the first blocking part to ensure that the first blocking part can be fixed on the first base ring 201.

[0044] To facilitate the installation of the second blocking part, a second annular groove is provided on the bottom of the second base ring 202. The second annular groove penetrates the inner peripheral wall of the second base ring 202 at the same time. The second blocking part is coaxially inserted into the second annular groove during installation. The filtering device for traditional Chinese medicine processing is also set to include at least two second pressing pieces 9. The second pressing pieces 9 are arranged on the bottom of the second base ring 202. The plurality of second pressing pieces 9 are arranged circumferentially on the second base ring 202 and jointly support the bottom of the second blocking part to ensure that the degree of freedom of the second blocking part in the vertical direction can be restricted.

[0045] To facilitate the addition of traditional Chinese medicine or medicinal residues into the annular filter screen 3, a material inlet is provided at the top of the second sealing portion. The provision of the material inlet makes the second sealing portion an annular structure.

[0046] Optionally, to reduce the spillage of the liquid medicine from the material inlet and reduce the entry of impurities from the material inlet into the annular filter screen 3, a sealing piece 10 is inserted at the material inlet. The sealing piece 10 is arranged in a disc shape and is configured to be able to open or close the material inlet. To facilitate the installation of the sealing piece 10, a third annular groove is provided through the top on the inner peripheral wall of the second sealing portion. A ring platform is provided on the circumferential side wall of the sealing piece 10 near the top. The ring platform is inserted into the third annular groove during installation and forms a keying fit with the second sealing portion.

[0047] Optionally, the first base ring 201 can be spaced from the bottom of the pot body 1 through a support.

[0048] During the use process, first remove the sealing piece 10 to open the material inlet, then add the medicinal residues into the annular filter screen 3, then seal the material inlet with the sealing piece 10, and then drive the second sealing portion to rotate around the axis of the annular filter screen 3, so that the annular filter screen 3 undergoes a torsional deformation with the first sealing portion as a reference to squeeze the medicinal residues, enabling the residual liquid medicine in the medicinal residues to be extruded and flow into the pot body 1, thereby realizing the recovery of the liquid medicine and reducing resource waste.

[0049] Optionally, the first base ring 201 can be connected to the inner peripheral wall at the top of the pot body 1 through a telescopic rod.

[0050] During the use process, first adjust the telescopic rod to the longest state so that the first base ring 201 is closer to the bottom of the pot body 1, then remove the sealing piece 10 to open the material inlet, then add the traditional Chinese medicine into the annular filter screen 3, then seal the material inlet with the sealing piece 10, then add water into the pot body 1 to submerge the annular filter screen 3, and then heat the pot body 1 to promote the full dissolution of the effective components in the traditional Chinese medicine into the water to form a liquid medicine. Then adjust the telescopic rod to the shortest state so that the annular filter screen 3 is above the liquid level of the liquid medicine, and then drive the second sealing portion to rotate around the axis of the annular filter screen 3, so that the annular filter screen 3 undergoes a torsional deformation with the first sealing portion as a reference to squeeze the medicinal residues, enabling the residual liquid medicine in the medicinal residues to be extruded and flow into the pot body 1, thereby realizing the recovery of the liquid medicine and reducing resource waste.

[0051] In some embodiments, the sealing portion 4 is provided as a hemispherical elastic structure. The annular filter screen 3 has corresponding first and second states before and after deformation. When in the first state, both sealing portions 4 bulge outwards, and when in the second state, both sealing portions 4 bulge inwards.

[0052] Specifically in this embodiment, to ensure the connection between the first sealing portion and the first pressing piece 8, and the connection between the second sealing portion and the second pressing piece 9, mounting rings 401 are fixedly sleeved on the outer peripheries of the first sealing portion and the second sealing portion. The mounting rings 401 are arranged as rigid structures, and the mounting ring 401 of the first sealing portion is inserted into the first annular groove, and the mounting ring 401 of the second sealing portion is inserted into the second annular groove.

[0053] The sealing portion 4 can be made of any one of silicone rubber, thermoplastic elastomer (TPE), natural rubber, or polyurethane elastomer. Among them, silicone rubber has good elasticity, flexibility, and chemical corrosion resistance, can maintain stable performance within a large deformation range, is not easy to age and crack, and is suitable for making the sealing portion 4 that needs to be deformed frequently. At the same time, silicone rubber also has the characteristics of being non-toxic and odorless, meeting the hygienic requirements of traditional Chinese medicine processing; thermoplastic elastomer (TPE) combines the elasticity of rubber and the processing performance of plastic, can be formed by heating, and is easy to process into various shapes. TPE has good elastic recovery, can quickly return to the initial shape, and has good wear resistance and tear resistance, and can withstand a certain degree of extrusion and torsion; natural rubber has high elasticity, good tensile strength, and flexibility, can withstand large deformations without breaking, is harmless to the human body, and has good water resistance, and can adapt to the humid environment in the process of traditional Chinese medicine processing; polyurethane elastomer has excellent wear resistance, tear resistance, and elasticity, can maintain good performance under different temperature conditions, and the hardness and elastic modulus of polyurethane elastomer can also be changed by adjusting the formula to meet different usage requirements.

[0054] Initially, the annular filter screen 3 is in the first state, and both the first sealing portion and the second sealing portion bulge outwards. At this time, the internal space enclosed by the annular filter screen 3 and the first sealing portion and the second sealing portion is larger, so that more traditional Chinese medicine can be placed, which is beneficial to improving the efficiency of preparing the medicinal liquid and the filtering efficiency, and more medicinal residues can also be placed, which is beneficial to improving the filtering efficiency.

[0055] During use, drive the second sealing portion to rotate around the axis of the annular filter screen 3, and the annular filter screen 3 begins to twist and deform with the first sealing portion as the reference, gradually transitioning from the first state to the second state. In this process, due to the elastic characteristics, when the hemispherical second sealing portion receives the force brought by the torsion of the annular filter screen 3, it begins to gradually bulge inwards. This inward bulging deformation is not sudden and irregular, but occurs slowly and evenly as the torsion degree of the annular filter screen 3 increases.

[0056] Meanwhile, although the first blocking part is fixedly arranged on the frame 2, due to the overall torsional deformation of the annular filter screen 3 and its own elasticity, it will also bulge inward synchronously. This inward bulging deformation of the first blocking part and the second blocking part forms a squeezing effect on the medicinal residues inside the annular filter screen 3 from both ends to the center. This squeezing effect not only compresses the medicinal residues along the radial direction of the annular filter screen 3, but also flips and further squeezes the medicinal residues in the axial direction, greatly improving the uniformity of the distribution of the medicinal residues.

[0057] Moreover, as the degree of inward bulging deformation of the first blocking part and the second blocking part deepens, the contact area between the annular filter screen 3 and the medicinal residues increases, and the squeezing force exerted by the annular filter screen 3 on the medicinal residues also increases accordingly. This enables the residual liquid medicine in the medicinal residues to be more fully squeezed out and flow into the pot body 1 along the mesh holes of the annular filter screen 3, thereby effectively improving the recovery efficiency of the liquid medicine and reducing the waste of resources.

[0058] In addition, after the annular filter screen 3 is deformed, both the first blocking part and the second blocking part tend to bulge inward further under the action of elasticity, so as to continuously exert pressure on the annular filter screen 3, which is beneficial to improving the squeezing effect on the medicinal residues.

[0059] In some other embodiments, the filtration device for traditional Chinese medicine processing is further provided with a plurality of torsion rods 5. The torsion rods 5 extend along the axial direction of the annular filter screen 3 and are fixedly arranged on the outer peripheral wall of the annular filter screen 3. The plurality of torsion rods 5 are arranged circumferentially, and both ends of the torsion rods 5 are ball-jointed to the two blocking parts 4 respectively.

[0060] Specifically in this embodiment, the bottom end of the torsion rod 5 is ball-jointed to the top of the first blocking part, and the top end is ball-jointed to the bottom of the second blocking part.

[0061] During the use process, as the second blocking part rotates, the second blocking part will drive the top end of the torsion rod 5 ball-jointed thereto to rotate synchronously; based on the characteristics of the ball joint, during the process of the torsion rod 5 following the rotation of the second blocking part, it can flexibly change its inclination angle in different directions, and then apply a multi-directional torsional force to the annular filter screen 3; the plurality of torsion rods 5 arranged circumferentially act on the outer peripheral wall of the annular filter screen 3 at the same time, so that the annular filter screen 3 can undergo more uniform and efficient torsional deformation with the first blocking part as the reference; this uniform torsional deformation prompts the annular filter screen 3 to squeeze the internal medicinal residues in all directions and more fully, thereby further improving the efficiency of squeezing out the residual liquid medicine in the medicinal residues, enabling more liquid medicine to flow into the pot body 1, and thus greatly improving the effect of liquid medicine recovery and significantly reducing the waste of resources.

[0062] Furthermore, when the blocking part 4 is arranged as a hemispherical elastic structure, during use, as the second blocking part rotates, the top of the torsion rod 5 ball-jointed to it starts to move in a circular motion around the axis of the annular filter screen 3. Since the torsion rods 5 are circumferentially distributed and fixed on the outer peripheral wall of the annular filter screen 3, they synchronously and coordinately transmit this rotation to the annular filter screen 3 under the drive of the second blocking part.

[0063] Under the push of the torsion rod 5, the annular filter screen 3 gradually undergoes torsional deformation with the first blocking part as the reference. Because both ends of the torsion rod 5 are connected to the two blocking parts 4 by ball-jointed means, this connection endows the torsion rod 5 with the flexibility of multi-dimensional rotation in space, enabling it to adaptively adjust its own posture according to the rotation angle and the deformation requirements of the annular filter screen 3 when driving the annular filter screen 3 to deform. Therefore, the annular filter screen 3 can uniformly and stably transition from the first state to the second state under the drive of the torsion rod 5.

[0064] As the annular filter screen 3 undergoes torsional deformation, due to its elastic characteristics, the hemispherical second blocking part starts to gradually bulge inward under the action force generated by the torsion of the annular filter screen 3; at the same time, although the first blocking part is fixed on the frame 2, due to the overall torsional deformation of the annular filter screen 3 and its own elasticity, it will also bulge inward synchronously; during this process, the torsion rod 5 not only ensures the uniformity of the deformation of the annular filter screen 3, but also further enhances the extrusion effect of the first blocking part and the second blocking part on the medicinal residues inside the annular filter screen 3.

[0065] Viewed radially, the torsion rod 5 drives the annular filter screen 3 to compress the medicinal residues, so that the medicinal residues are subjected to a uniform extrusion force in the circumferential direction; viewed axially, as the torsion rod 5 rotates with the blocking part 4, it pushes the annular filter screen 3 to turn and further extrude the medicinal residues in the axial direction, greatly improving the uniformity of the distribution of the medicinal residues; as the degree of inward convex deformation of the first blocking part and the second blocking part deepens, the contact area between the annular filter screen 3 and the medicinal residues increases. Coupled with the additional support and extrusion force provided by the torsion rod 5, the extrusion force exerted by the annular filter screen 3 on the medicinal residues significantly increases, enabling the residual liquid medicine in the medicinal residues to be more fully squeezed out and flow into the pot body 1 along the mesh holes of the annular filter screen 3, thereby further effectively improving the recovery efficiency of the liquid medicine and reducing the waste of resources.

[0066] In some other embodiments, to facilitate the rotation of the second blocking part around the axis of the annular filter screen 3, a rotation hole is provided on the rotatable blocking part 4. The filtering device for traditional Chinese medicine processing further includes a rotating member, and the rotating member can be clamped at the rotation hole and can rotate around the axis of the annular filter screen 3.

[0067] Specifically in this embodiment, the rotation hole can be arranged on the sealing piece 10; at the top of the second sealing part, a plurality of slots are arranged at the position of the third annular groove, and a plurality of insertion protrusions are arranged at the bottom of the annular platform of the sealing piece 10. The plurality of insertion protrusions are arranged circumferentially, and the insertion protrusions are inserted into the slots during installation to ensure that when the sealing piece 10 rotates, the second sealing part can be driven to rotate through the clamping cooperation between the insertion protrusions and the slots.

[0068] Further, the rotation hole is of a cross-shaped structure; the rotating member is of a rod-shaped structure, and the cross-sectional shape is cross-shaped. In this way, the cross-shaped cross-section of the rotating member can be closely adapted to the cross-shaped structure of the rotation hole to achieve precise clamping. This special shape matching, on the one hand, ensures that the rotating member will not have radial displacement in the rotation hole, making the rotation process more stable and avoiding the second sealing part from rotating smoothly or deviating due to shaking; on the other hand, when the operator holds the rotating member and applies a rotational force, due to the tight engagement between the rotating member and the rotation hole, the force can be efficiently transmitted to the sealing piece 10 and the second sealing part, so as to drive the second sealing part to rotate smoothly around the axis of the annular filter screen 3.

[0069] In some other embodiments, to facilitate the vertical movement of the frame 2, the filtering device for traditional Chinese medicine processing is further provided with a bracket 6 and a hook 7. The bracket 6 is arranged on the pot body 1; the hook 7 is simultaneously hooked on the bracket 6 and the frame 2.

[0070] Specifically in this embodiment, the bracket 6 is provided with a third base ring 601 and a plurality of support rods 602. The third base ring 601 is horizontally arranged on the top of the frame 2 during installation; the plurality of support rods 602 are arranged circumferentially along the third base ring 601. The support rods 602 are of an L-shaped structure. The long ends of the support rods 602 are arranged on the outer peripheral wall of the third base ring 601 and extend along the radial direction of the third base ring 601. The short ends of the support rods 602 abut against the outer peripheral wall of the pot body 1; the bracket 6 is lapped on the top of the pot body 1 through the support rods 602 during installation; the hook 7 is of an E-shaped structure. A first insertion rod is vertically arranged at the bottom of the uppermost cantilever of the hook 7. A first installation hole is arranged at the top of the third base ring 601. The first insertion rod is inserted into the first installation hole during installation. Second insertion rods are arranged at the tops of the middle cantilever and the lowermost cantilever of the hook 7. Second installation holes are arranged at the top of the second base ring 202. The second insertion rods are inserted into the second installation holes during installation.

[0071] During the use process, when decocting traditional Chinese medicine is required, the second installation hole is sleeved on the second insertion rod of the lowermost cantilever of the hook 7, so that the first base ring 201 is closer to the bottom of the pot body 1; when filtering medicinal residues is required, the second installation hole is sleeved on the second insertion rod of the middle cantilever of the hook 7, so that the first base ring 201 is farther from the bottom of the pot body 1, and the annular filter screen 3 is located above the liquid level of the medicinal liquid.

[0072] In a further embodiment, there are multiple hooks 7, which are arranged circumferentially. In this way, the stability and reliability of the movement of the frame 2 in the vertical direction can be improved, so that the multiple hooks 7 jointly bear the weights of the frame 2, the annular filter screen 3, the residue of the medicine slag, etc., avoiding the situation that the frame 2 tilts or shakes due to uneven single-point force.

[0073] In some other embodiments, a plurality of filter holes are provided on the blocking portion 4. In this way, when the annular filter screen 3 squeezes the residue of the medicine slag, the liquid medicine remaining in the residue of the medicine slag can flow out more efficiently through the filter holes on the first blocking portion and the second blocking portion. The existence of these filter holes increases the channels for the liquid medicine to drain, thereby greatly improving the filtering efficiency.

[0074] In some other embodiments, a handle 101 is provided on the pot body 1.

[0075] Specifically in this embodiment, the handle 101 is provided on the outer peripheral wall of the pot body 1. In this way, it is convenient for the operator to hold, improving the simplicity during the use of the device.

[0076] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0077] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
