Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine liquid filtration technology, and specifically relates to a traditional Chinese medicine liquid filtration fixture with variable pore size. Background Technology

[0002] As is well known, filtration is an indispensable and crucial step in the decoction process of traditional Chinese medicine. Its main purpose is to remove dregs, sediment, and impurities, ensuring the purity and safety of the medicinal liquid. Filtration prevents ineffective components or tiny particles in the dregs from affecting the taste or even irritating the gastrointestinal tract and causing discomfort. At the same time, the effective removal of impurities in the medicinal liquid reduces the risk of microbial growth and facilitates preservation. Filtration is typically performed using tools such as filter screens to avoid squeezing the dregs and causing turbidity, ensuring the medicinal liquid is clear and transparent.

[0003] Special and precious Chinese herbal medicine liquids are filtered through two layers of coarse and fine filters to efficiently remove impurities: the coarse filter intercepts large particles of medicinal residue and protects the fine filter from clogging; the fine filter further traps tiny impurities, improving the purity of the liquid while avoiding excessive adsorption of active ingredients, ensuring that the medicinal components are fully preserved.

[0004] Regarding the above-mentioned coarse and fine filter filtration, in practice it has been found that when workers pour the entire barrel of Chinese medicine liquid to be filtered into the upper coarse filter, if the drop hole diameter at the bottom of the coarse filter is not adjusted, the instantaneously falling Chinese medicine liquid will not only impact the fine filter, causing its mesh to deform and enlarge, reducing the filtration accuracy, but the Chinese medicine liquid may also splash out from the fine filter, resulting in waste and loss. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a variable pore size filter for traditional Chinese medicine liquids. The specific technical solution is as follows: This utility model provides a variable pore size traditional Chinese medicine liquid filtration fixture, including a support frame. The support frame is longitudinally spaced from top to bottom with an upper conical hopper and a lower conical hopper. An upper filter element is axially detachably mounted on the upper part of the inner wall of the upper conical hopper, and a lower filter element is axially detachably mounted on the upper part of the inner wall of the lower conical hopper. The pore size of the upper filter element is larger than that of the lower filter element. A variable diameter conical hopper is integrally axially connected to the bottom opening of the upper conical hopper. The variable diameter conical hopper adjusts its own liquid discharge orifice size through a variable diameter component suspended above it. The variable diameter assembly includes a suspension frame that is radially detachably mounted on the top surface of the upper conical bucket. A circular support rod is vertically inserted through the middle of the suspension frame, and the upper part of the circular support rod is threadedly connected to the suspension frame, while the lower part passes through the upper filter element. A double conical piston is axially connected to the bottom end of the circular support rod, and the middle dimension of the double conical piston is adapted to the top opening dimension of the variable diameter conical bucket.

[0006] As a preferred technical solution of this utility model, the lower part of the top opening of the upper cone bucket is integrally connected with an annular protrusion, and an upper filter element is detachably and horizontally installed on the annular protrusion. The upper filter element includes a circular hoop of the same size as the annular protrusion, which is fixedly connected to the annular protrusion by bolts arranged at equal intervals around the circumference; a circular ring is provided at the center of the circular hoop, and the inner diameter of the circular ring is the same as the outer diameter of the circular support rod. The circular ring is fixedly connected to the circular hoop by four support ribs arranged at equal intervals around the circumference. The upper filter screen is tensioned and connected to the fan-shaped area formed by two adjacent support ribs and the circular hoop.

[0007] As a preferred technical solution of this utility model, the lower part of the top opening of the lower cone bucket is integrally connected with an annular protrusion 2, and a lower filter element is detachably and horizontally installed on the annular protrusion 2. The lower filter element includes a circular hoop of the same size as the annular protrusion, which is fixedly connected to the annular protrusion by bolts arranged at equal intervals in the circumference; a lower filter screen is tensioned and connected inside the circular hoop; the pore size of the lower filter screen is smaller than that of the upper filter screen.

[0008] As a preferred embodiment of this invention, the size of the upper conical hopper is larger than the size of the lower conical hopper.

[0009] As a preferred technical solution of this utility model, the bottom opening of the variable diameter conical bucket is integrally axially connected with a flared mouth.

[0010] As a preferred technical solution of this utility model, the suspension frame is an inverted right-angled U-shaped structure, with the inner side of its vertical part attached to the outer peripheral wall of the upper cone, and the two are fixedly connected by a matching bolt.

[0011] As a preferred embodiment of this utility model, the top of the round support rod has a square hole axially opened inward, and a T-shaped handle is longitudinally inserted into the square hole.

[0012] As a preferred technical solution of this utility model, the double cone piston is provided with an inwardly inclined annular slope in the middle circumferential direction, and the annular slope can be in contact with the top opening of the variable diameter cone bucket.

[0013] As a preferred embodiment of this utility model, the support frame includes a first bracket that is axially engaged with the upper cone bucket and a second bracket that is axially engaged with the lower cone bucket. The bottom surface of the first bracket is vertically connected with three main support rods at equal intervals along its circumference. The second bracket is vertically connected to the three main support rods by horizontally arranged auxiliary support rods. The bottom surface of the main support rods is vertically connected with a circular base plate.

[0014] As a preferred technical solution of this utility model, a liquid receiving tank is placed directly below the bottom opening of the lower cone bucket; a U-shaped platform is horizontally arranged around the outside of the support frame, with the inner bottom surface of the platform facing one of the main support rods, and a matching step ladder abutting its outer bottom surface.

[0015] The beneficial effects of this utility model are: 1. This utility model incorporates a variable-diameter component, particularly the cooperation between the double-cone piston at its bottom and the variable-diameter conical hopper. In the initial stage of pouring the liquid medicine, the flow rate is high and the impact force is strong. At this time, the worker can lower the double-cone piston by rotating the circular support rod, causing it to enter the top opening of the variable-diameter conical hopper, thereby reducing the effective droplet diameter. This allows the liquid medicine to flow down in a finer, gentler columnar or curtain-like pattern, rather than directly impacting the lower filter element with a surging torrent. This avoids the risk of deformation, enlargement, or even damage to the filter mesh of the lower filter element caused by the instantaneous impact of the high-pressure liquid flow, fundamentally ensuring the filtration accuracy and structural integrity of the lower filter element, ensuring the long-term stability and consistency of the filtration effect, and thus guaranteeing the purity of the liquid medicine.

[0016] 2. This invention controls the flow rate and volume of the liquid by adjusting the position of the double-cone piston. When the drop orifice diameter is appropriately reduced, the liquid falls smoothly and concentratedly, remaining entirely within the receiving range of the lower conical hopper. This solves the problem of liquid splashing out from the edge of the lower filter element or overflowing due to violent impact when the flow is too rapid. It minimizes unnecessary loss and waste of precious medicinal liquid during the filtration process, saving costs while maintaining a clean and hygienic working environment.

[0017] 3. In this utility model, the circular support rod and the suspension frame are connected by threads. This allows the operator to adjust the lifting and lowering of the double-cone piston in real time, manually, and steplessly, according to the instantaneous flow rate and velocity of the liquid in the tank, thereby dynamically changing the effective outlet orifice diameter of the variable-diameter cone. When the liquid flow is strong, the orifice diameter can be reduced to buffer the flow; when the liquid flow is stable or the liquid level is low, the orifice diameter can be appropriately increased to accelerate the filtration speed.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. Example 1

[0021] To address the technical problems in the background section, the following variable pore size traditional Chinese medicine liquid filtration fixture is provided: Combination Figures 1-4 As shown, a variable pore size traditional Chinese medicine liquid filtration fixture includes a support frame 1. The support frame 1 is longitudinally spaced from top to bottom with an upper conical hopper 2 and a lower conical hopper 3. An upper filter element 21 is axially and detachably mounted on the upper part of the inner wall of the upper conical hopper 2, and a lower filter element 31 is axially and detachably mounted on the upper part of the inner wall of the lower conical hopper 3. The pore size of the upper filter element 21 is larger than that of the lower filter element 31. A variable diameter conical hopper 22 is integrally and axially connected to the bottom opening of the upper conical hopper 2. The variable diameter conical hopper 22 adjusts its own liquid discharge orifice size through a variable diameter component 4 suspended above it. The variable diameter assembly 4 includes a suspension frame 41 that is radially detachably mounted on the top surface of the upper conical bucket 2. A circular support rod 42 is vertically inserted through the middle of the suspension frame 41, and the upper part of the circular support rod 42 is threadedly connected to the suspension frame 41, while the lower part passes through the upper filter element 21. A double conical piston 43 is axially connected to the bottom end of the circular support rod 42, and the middle dimension of the double conical piston 43 is adapted to the top opening dimension of the variable diameter conical bucket 22.

[0022] In the above technical solution, the herbal liquid filtration fixture incorporates a variable diameter component 4, particularly the cooperation between the double-cone piston 43 at its bottom and the variable-diameter conical hopper 22. In the initial stage of pouring the liquid, the flow rate is high and the impact force is strong. At this time, the worker can rotate the circular support rod 42 to lower the double-cone piston 43, causing it to enter the top opening of the variable-diameter conical hopper 22, thereby reducing the effective droplet diameter. This allows the liquid to flow down in a finer, gentler columnar or curtain-like pattern, rather than directly impacting the lower filter element 31 with a surging torrent. This avoids the risk of deformation, enlargement, or even damage to the filter mesh of the lower filter element 31 caused by the instantaneous impact of the high-pressure liquid flow, fundamentally ensuring the filtration accuracy and structural integrity of the lower filter element 31, ensuring the long-term stability and consistency of the filtration effect, and thus guaranteeing the purity of the liquid.

[0023] This herbal medicine filtration fixture controls the flow rate and volume of the liquid by adjusting the position of the double-cone piston 43. When the drop orifice diameter is appropriately reduced, the liquid falls smoothly and concentratedly, remaining entirely within the receiving range of the lower conical hopper 3. This solves the problem of liquid splashing out from the edge of the lower filter element 31 or overflowing due to violent impact when the flow is too rapid. It minimizes unnecessary loss and waste of precious medicinal liquid during the filtration process, saving costs while maintaining a clean and hygienic working environment.

[0024] In this herbal liquid filtration fixture, the circular support rod 42 and the suspension frame 41 are connected by threads. This allows the operator to adjust the lifting and lowering of the double-cone piston 43 in real time, manually, and steplessly, according to the instantaneous flow rate and velocity of the liquid in the tank, thereby dynamically changing the effective outlet orifice diameter of the variable-diameter cone 22. When the liquid flow is rapid, the orifice diameter can be reduced to buffer the flow; when the flow is stable or the liquid level is low, the orifice diameter can be appropriately increased to accelerate the filtration speed.

[0025] This herbal liquid filtration fixture retains the standard two-stage filtration structure of upper filter element 21 and lower filter element 31, and all filter elements are detachable. Because the pore size of the upper filter element 21 is larger than that of the lower filter element 31, the upper filter element 21 first intercepts most of the medicinal residue, protecting the lower filter element 31 from clogging by large particles; the lower filter element 31 is responsible for improving the purity of the final liquid. The detachable design facilitates thorough cleaning and replacement, avoiding cross-contamination. This ensures the effectiveness of staged filtration, effectively removing impurities and medicinal residue, guaranteeing the oral safety and taste of the liquid, while preventing excessive adsorption of active ingredients onto the filter media, ensuring the full exertion of the medicinal efficacy.

[0026] like Figure 5 As shown, the lower part of the top opening of the upper cone bucket 2 is integrally connected with an annular protrusion 24, and an upper filter element 21 is detachably and horizontally installed on the annular protrusion 24. The upper filter element 21 includes a circular hoop 211 with the same size as the annular protrusion 24. The circular hoop 211 and the annular protrusion 24 are fixedly connected by bolts arranged at equal intervals in the circumference. A circular ring 212 is provided at the center of the circular hoop 211, and the inner diameter of the circular ring 212 is the same as the outer diameter of the circular support rod 42. The circular ring 212 and the circular hoop 211 are fixedly connected by four supporting edges 213 arranged at equal intervals in the circumference. The upper filter screen 214 is tensioned and connected to the fan-shaped area formed by two adjacent supporting edges 213 and the circular hoop 211.

[0027] like Figure 6 As shown, the lower part of the top opening of the lower cone bucket 3 is integrally connected with an annular protrusion 32, and a lower filter element 31 is detachably and horizontally installed on the annular protrusion 32. The lower filter element 31 includes a circular hoop 311 of the same size as the annular protrusion 32. The circular hoop 311 and the annular protrusion 32 are fixedly connected by bolts arranged at equal intervals in the circumference. A lower filter screen 312 is tensioned and connected inside the circular hoop 311. The pore size of the lower filter screen 312 is smaller than that of the upper filter screen 214.

[0028] like Figures 1-3 As shown, the size of the upper conical hopper 2 is larger than the size of the lower conical hopper 3.

[0029] In the above technical solution, both the upper and lower filter elements adopt a modular design and are fixed to the annular protrusions inside their respective conical hoppers by bolts spaced circumferentially at equal intervals. This design transforms the filter element into an independent, standardized module. When cleaning or replacing filter screens with different pore sizes is required, workers only need to unscrew the bolts to remove the entire filter element, making the operation very simple and greatly improving the maintainability of the equipment.

[0030] By using the planar fit between the circular hoop and the annular convex ridge, and by tightening the bolts evenly around the circumference, it is ensured that the filter element will not shift or loosen when subjected to the weight and impact of the liquid medicine. At the same time, it prevents the liquid medicine from leaking from the gap between the edge of the filter screen and the conical wall, ensuring that all liquid medicine must be filtered through the filter screen.

[0031] Because the upper filter element 21 is relatively large, its support ribs 213 act as reinforcing ribs, effectively resisting the impact of the liquid and preventing the center of the upper filter screen 214 from deforming. At the same time, this design maximizes the effective area of ​​the upper filter screen 214 while ensuring the overall structural rigidity, thus guaranteeing the flow efficiency during the coarse filtration stage.

[0032] The upper conical hopper 2 is larger than the lower conical hopper 3, which can increase the coarse filtration area, accommodate more liquid, and buffer the flow rate. At the same time, it provides a larger receiving area for the lower conical hopper 3, which can effectively collect any splashing droplets. In conjunction with the flared mouth (23), it ensures that the liquid flow can be more concentrated and guided to the central area of ​​the lower filter element 31, thus optimizing the connection between the two stages of filtration.

[0033] like Figure 4 As shown, the suspension frame 41 is an inverted right-angled U-shaped structure, with the inner side of its vertical part attached to the outer peripheral wall of the upper cone 2, and the two are fixedly connected by a matching bolt.

[0034] In the above technical solution, the suspension frame 41 is connected across the top of the upper cone bucket 2, has a large contact area with the outer wall of the upper cone bucket 2, and is fastened with bolts, providing a very stable support base for the round support rod 42 and the entire variable diameter assembly 4, preventing it from shaking during adjustment and under stress.

[0035] like Figure 4 As shown, the top of the circular support rod 42 has a square hole 421 axially opened inward, and a T-shaped handle 44 is longitudinally inserted into the square hole 421.

[0036] In the above technical solution, a square hole 421 is opened at the top of the circular support rod 42, and the handle 44 that matches it is a T-shaped structure with a cube at the bottom, which can be inserted into the hole. The square cross-section can transmit rotational torque without slippage, ensuring that when the handle 44 is rotated to adjust the height of the double cone piston 43, the force can be fully applied to the circular support rod 42, avoiding the slippage and free rotation that may occur when directly rotating the circular support rod 42, making the adjustment operation precise and labor-saving.

[0037] The handle 44 can be inserted and removed at any time; it can be inserted for operation when working and removed when not working, reducing external protrusions of the equipment and making it easy to store; this design also provides operating space and convenience for later disassembly of the suspension frame 41 and the entire variable diameter assembly 4 to replace the upper filter element 21.

[0038] like Figure 3 and Figure 4 As shown, the double cone piston 43 has an inwardly inclined annular slope 431 circumferentially arranged in the middle part, and the annular slope 431 can be in contact with the top opening of the variable diameter cone hopper 22.

[0039] In the above technical solution, when the double cone piston 43 descends to the lowest position, the annular inclined surface 431 and the top opening of the variable diameter cone hopper 22 can be tightly connected to achieve effective sealing, which can completely cut off the liquid flow or prevent residual liquid from dripping after filtration.

[0040] like Figure 2 and Figure 3 As shown, the bottom opening of the variable diameter cone bucket 22 is integrally axially connected with a flared opening 23.

[0041] In the above technical solution, a downwardly expanding flared mouth 23 is integrally connected to the bottom opening of the variable-diameter conical hopper 22. This flared mouth 23 can quickly diffuse the concentrated liquid flow after the diameter adjustment into a larger liquid curtain. This allows the medicine to be sprayed more evenly on the central area and even a larger area of ​​the lower filter element 31. By expanding the distribution area of ​​the medicine on the lower filter screen 312, the long-term impact of the liquid flow on the same point on the lower filter screen 312 is avoided, thereby effectively utilizing the filtration area of ​​the entire lower filter screen 312. This not only improves the filtration efficiency per unit time, but also prevents the fine filter screen from being blocked prematurely due to excessive local load, thus extending the cycle of a single use.

[0042] like Figures 1-3 As shown, the support frame 1 includes a first clamp 11 that is axially engaged with the upper cone 2 and a second clamp 13 that is axially engaged with the lower cone 3. The bottom surface of the first clamp 11 is vertically connected with three main support rods 12 at equal intervals. The second clamp 13 is vertically connected to the three main support rods 12 by horizontally arranged auxiliary support rods 131. The bottom surface of the main support rods 12 is vertically connected with a circular base plate 121.

[0043] In the above technical solution, the first bracket 11 and the second bracket 13 of the support frame 1 facilitate the assembly and disassembly of the upper conical bucket 2 and the lower conical bucket 3. The three main support rods 12 are arranged at equal intervals around the circumference and connected to the second bracket 13 via the auxiliary support rod 131, forming a robust tripod structure that ensures the stability of the entire equipment during operation and prevents tipping. The clamping method of the brackets facilitates the installation and positioning of the upper and lower conical buckets, and also facilitates future disassembly and maintenance. The circular base plate 121 at the bottom further increases the contact area with the ground, enhancing stability. Example 2

[0044] Combination Figure 7 As shown, based on the above embodiments, this embodiment further provides the following: In this embodiment, a liquid receiving tank 5 is placed directly below the bottom opening of the lower cone hopper 3; a U-shaped platform 6 is horizontally arranged around the outside of the support frame 1, with the inner bottom surface of the platform 6 facing one of the main support rods 12, and a matching step ladder 61 abutting its outer bottom surface.

[0045] In the above technical solution, the traditional Chinese medicine liquid is usually stored in a bucket. Platform 6 raises the operating surface to a suitable height, allowing workers to easily pour the liquid into the upper conical hopper 2 without having to laboriously lift the heavy bucket over their shoulders, greatly reducing the operator's labor intensity and the risk of lower back injury. Ladder 61 provides a safe passage for going up and down the platform.

[0046] The three-sided surrounding structure of the U-shaped platform 6 provides stable support for the operator. At the same time, the inner bottom surface of the platform 6 is directly opposite one of the main support rods 12, creating an unobstructed access passage on the side of the support frame 1. Workers can easily pass through this passage to put or take out the liquid receiving tank 5 from directly below the lower conical hopper 3.

[0047] Working principle and usage process of this utility model: In use, the operator first ascends to platform 6 via ladder 61 and places the container containing the herbal liquid to be filtered above the upper conical hopper 2. At this point, the height of the double-conical piston 43 can be pre-adjusted by inserting handle 44 and rotating the circular support rod 42, depending on the volume of liquid. If the liquid flow is rapid, the double-conical piston 43 is lowered so that its annular inclined surface 431 is close to the top opening of the variable-diameter conical hopper 22, thereby reducing the outlet diameter; if the liquid flow is gentle, the double-conical piston 43 is raised to increase the orifice diameter.

[0048] The medicinal liquid is then poured smoothly into the upper conical hopper 2. The liquid first undergoes preliminary filtration through the upper filter element 21, intercepting large particles of medicinal residue. The coarsely filtered liquid flows into the lower variable-diameter conical hopper 22, exiting through an adjusted annular slit to form a controlled liquid column. This column diffuses through the funnel-shaped opening 23, then evenly and gently sprinkles onto the lower filter element 31 for precision filtration, effectively preventing impact splashes and mesh deformation.

[0049] Finally, the purified medicine solution, after two stages of filtration, flows out from the bottom of the lower conical hopper 3 and is completely collected by the receiving tank 5 directly below. After filtration, the upper filter element 21 and the lower filter element 31 can be removed for cleaning or replacement, and the reducing assembly 4 can be removed for maintenance.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
