Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing, specifically a filter structure for a traditional Chinese medicine extraction device. Background Technology

[0002] Traditional Chinese medicine (TCM) mainly comes from natural medicines and their processed products, including plant-based medicines, animal-based medicines, mineral-based medicines, and some chemical and biological products. In the extraction process of TCM materials, it is usually necessary to soak and heat the materials to extract the effective components. However, during the extraction process, some impurities in the TCM materials, such as residues and fine fibers, will mix into the extract, affecting the purity of the extract and subsequent processing and utilization.

[0003] Traditional filtration methods often use filter screens for preliminary filtration, but their filtration effect is poor and cannot effectively remove these impurities, resulting in low quality of the extract. In addition, some filter screens are integrated with the filtration device, making it difficult to disassemble the filter screen. This causes the medicinal residue on the filter screen to accumulate and clog, affecting the subsequent filtration effect. Therefore, a filtration structure for a Chinese herbal medicine extraction device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filtration structure for a Chinese herbal medicine extraction device. This structure enables double-layer filtration of the herbs, enhancing the filtration effect. It also allows for easy disassembly and replacement of both filter layers. This solves the problems of traditional filtration methods, which often rely solely on filter screens for initial filtration, resulting in poor filtration efficiency and inability to effectively remove impurities, leading to low-quality extracts. Furthermore, some filter screens are integrated with the filtration device, making them difficult to disassemble and causing herbal residue to accumulate and clog the screen, thus affecting subsequent filtration.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the embodiments, by Figure 1-6 The present invention discloses a filtration structure for a Chinese herbal medicine extraction device. The present invention includes a fixed frame 1, a heating tank 2 on the top of the fixed frame 1, a first discharge pipe 3 fixedly connected inside the heating tank 2, a filter tank 4 fixedly connected inside the fixed frame 1, a cover plate 5 threadedly connected to the outside of the filter tank 4, a plurality of support rods 6 fixedly connected inside the filter tank 4, all of the support rods 6 being slidably connected to a filter frame 7, a plurality of limiting rings 8 fixedly connected inside the filter frame 7, a stainless steel wire mesh filter layer 9 and a non-woven fabric filter layer 10 respectively fixedly connected to opposite sides of the two limiting rings 8 by fasteners, and a second discharge pipe 11 fixedly connected inside the filter tank 4.

[0030] The top of the fixed frame 1 is fixedly connected with a number of limiting rods 12, and the outer side of the heating barrel 2 is fixedly connected with a limiting plate 13 that is slidably connected to the limiting rods 12.

[0031] In this embodiment, during actual use, the heating barrel 2 can be placed directly on the fixed frame 1, and its docking with the limiting rod 12 can prevent the heating barrel 2 from moving randomly and prevent it from falling and being damaged due to accidental movement. The heating barrel 2 can be removed from the limiting rod 12 upwards so that the medicinal materials can be poured out or its interior can be cleaned.

[0032] The first discharge pipe 3 includes a stainless steel rigid pipe that is fixedly connected to the heating tank 2. The stainless steel rigid pipe is fixedly connected to the flexible hose through an adapter. Both the first discharge pipe 3 and the second discharge pipe 11 are equipped with a water valve.

[0033] In this embodiment, during actual use, the stainless steel rigid pipe facilitates the installation of the water valve and will not deform due to the heating of the medicine liquid by the heating tank 2. In addition, a filter screen can be installed on the stainless steel rigid pipe for preliminary filtration of large particles of medicinal materials. The flexible tube is a silicone flexible tube, which also has strong heat resistance and can be bent and moved, making it convenient to move and adjust the discharge position of the medicine liquid.

[0034] The cover plate 5 is fixedly connected to the limiting cylinder 14, and the first discharge pipe 3 passes through and extends into the interior of the limiting cylinder 14.

[0035] In this embodiment, during actual use, the first discharge pipe 3 can pass through the cover plate 5 by the position of the limiting cylinder 14 and discharge the medicine into the filter frame 7.

[0036] The top surface of the filter frame 7 is inclined inward, and the interior of the filter frame 7 has clearance holes that are slidably connected to multiple support rods 6. The outer side of the support rods 6 is fixedly connected with a fixing ring 15.

[0037] In this embodiment, during actual use, the inclined filter frame 7 facilitates the collection of the medicine liquid inside, so that the medicine liquid can be filtered through the filter layer. The threaded cover plate 5 can be unscrewed and removed. The filter frame 7 can be taken out of the filter barrel 4 by sliding with the support rod 6. The fixing ring 15 enhances the stability of the multiple support rods 6.

[0038] Among them, the stainless steel wire mesh filter layer 9 is located above the non-woven fabric filter layer 10. The opposite sides of the two limiting rings 8 are fixedly connected with a number of threaded rods 16 that pass through the stainless steel wire mesh filter layer 9 and the non-woven fabric filter layer 10 respectively. The outer sides of the multiple threaded rods 16 are all threadedly connected with threaded sleeves 17.

[0039] In this embodiment, during actual use, the stainless steel wire mesh filter layer 9 is used to intercept larger particles of impurities, while the non-woven fabric filter layer 10 can further filter out small impurities, improving filtration accuracy. A gap is left between the two filter layers, which can serve as a buffer zone, allowing the liquid to flow and be buffered after passing through the stainless steel wire mesh, giving more impurities a chance to be intercepted by the non-woven fabric filter layer, thereby improving filtration efficiency. A frame surrounds the edges of the two filter layers, and the engagement of the threaded rod 16 and the threaded sleeve 17 fixes the frame to the upper and lower sides of the filter frame 7 respectively, so that the two filter layers can be cleaned and replaced later.

[0040] Working principle:

[0041] When extracting Chinese medicinal materials, the heating tank 2 has a built-in heater, and the Chinese medicinal materials can be boiled inside the heating tank 2. Boiling is a common method for extracting Chinese medicinal materials. It can dissolve some effective components that are difficult to dissolve or have low efficacy at room temperature, and can also precipitate some insoluble impurities in the medicinal materials, making the medicinal liquid easier for the human body to absorb. The medicinal liquid after heating and extraction can be discharged into the filter tank 4 through the first discharge pipe 3. Alternatively, the medicinal liquid extracted by other equipment can be directly poured into the heating tank 2 or the filter tank 4. The medicinal liquid passes through the stainless steel wire mesh filter layer 9 and the non-woven fabric filter layer 10 to filter the medicinal liquid. The filtered medicinal liquid is discharged from the second discharge pipe 11 below. If it is necessary to replace or clean the two filter layers, the first discharge pipe 3 can be removed from the filter tank 4, the cover plate 5 can be unscrewed and the filter frame 7 can be removed from the filter tank 4, and the two filter layers can be removed by unscrewing the threaded sleeve 17.
