[0035] Traditional Chinese medicine extraction involves extracting the active ingredients from herbal medicines through methods such as decoction and maceration to obtain high-purity active ingredients. Filtration is necessary to achieve solid-liquid separation, thereby separating the medicinal materials and residues from the liquid medicine. However, in related prior art, the equipment used for liquid medicine filtration is overly complex, resulting in suboptimal filtration efficiency and difficulty in cleaning, making it difficult to maintain long-term filtration operations.

[0036] To this end, the utility model provides a filter rack that can take into account both filtering efficiency and cleaning, and can meet the needs of long-term filtering operations.

[0037] Reference Figure 1 and Figure 5 The filter frame of an embodiment of the present invention includes a filter frame 100 and a filter base 200, wherein the filter frame 100 is a conical structure, that is, a structure with a pointed upper end and an outwardly opened lower end; the filter base 200 is coaxially distributed with the filter frame 100, the filter base 200 is connected to the bottom of the filter frame 100, and the filter base 200 is provided with a filter structure 203.

[0038] The filter rack of the present invention, by providing a tapered filter rack 100, has a large filtration area. During filtration, the liquid can be quickly filtered by gravity and distributed along the surface of the filter rack 100, improving the filtration effect. Furthermore, the filter base 200 can be used to support the filter rack 100, ensuring its strength and rigidity, and can also be used to provide a secondary filtration. During filtration, the filter rack 100 can serve as a skeletal support, upon which the filter structure can be laid. Alternatively, an integrated design can be employed, such as densely packed filter racks 100 forming a first filtration layer and filter base 200 forming a second filtration layer, thereby improving the filtration effect based on the tapered design. Furthermore, the filter rack can be flushed directly from above, utilizing the impact of the water flow and gravity to quickly clean it. Surface residue is discharged downward along the inclined surface of the filter rack 100, while residue on the filter base 200 can be flushed outward under the action of the water flow. Therefore, the filter rack of the present invention takes into account both filtration and cleaning, can meet the needs of long-term filtration operations, and is not prone to clogging.

[0039] Reference Figures 1 to 4 In some embodiments of the present invention, the filter rack 100 includes a plurality of longitudinal support rods 101 and a plurality of support rings 102. Specifically, the upper ends of the longitudinal support rods 101 are connected together, and the lower ends are evenly connected to the edge of the filter chassis 200 to form a conical structure. In addition, along the circumferential direction, the spacing between any two adjacent longitudinal support rods 101 remains consistent, thereby ensuring a uniform filtering effect and avoiding local blockage. The support rings 102 connect all the longitudinal support rods 101 along the circumferential direction, thereby improving the structural strength and overall rigidity between the longitudinal support rods 101. In addition, when a plurality of support rings 102 are provided, the plurality of support rings 102 are distributed in the vertical direction, thereby reinforcing the filter rack 100 along the length direction of the longitudinal support rods 101. It can be understood that since the multiple longitudinal support rods 101 are distributed along a cone, the outer diameter of the contour formed by the longitudinal support rods 101 gradually increases from top to bottom. When multiple support rings 102 are set, the outer diameter sizes of the support rings 102 are not the same to meet the installation needs of different positions.

[0040] Since the bottom of the filter rack 100 is connected to the filter bottom plate 200 , the support ring 102 may only be provided at the middle position in the length direction of the longitudinal support rod 101 .

[0041] Specifically, the support ring 102 can be directly welded to the longitudinal support rod 101, or can be connected and fixed by means of clamping or splicing.

[0042] Reference Figures 1 to 5In some embodiments of the present invention, the filter rack further includes a mounting rod 300. The mounting rod 300 is vertically arranged, the upper end of the longitudinal support rod 101 is connected to the mounting rod 300, and the filter chassis 200 is connected to the bottom of the mounting rod 300. By providing the mounting rod 300 in this embodiment, the filter rack can be mounted to a specific filter device through the mounting rod 300, and the mounting rod 300 can also be used to improve the overall structural strength of the filter rack.

[0043] Reference Figures 1 to 5 In some embodiments of the present invention, the filter rack 100 further includes a positioning ring 103. The inner diameter of the positioning ring 103 matches the diameter of the mounting rod 300. The upper end of the longitudinal support rod 101 is connected to the positioning ring 103, and the positioning ring 103 is sleeved onto the mounting rod 300. It is understood that the positioning ring 103 and the mounting rod 300 in this embodiment do not need to be fixed, but only sleeved. In this way, the filter rack 100 and the filter chassis 200 can be removed from the mounting rod 300 for cleaning and maintenance. In addition, the provision of the positioning ring 103 for the installation of the longitudinal support rod 101 is conducive to improving the installation accuracy and convenience of the longitudinal support rod 101.

[0044] Reference Figure 3 and Figure 4 In some embodiments of the present invention, a threaded hole is provided in the center of the filter chassis 200, into which the mounting rod 300 is screwed. The use of the threaded hole to connect the mounting rod 300, combined with the design of the locating ring 103, allows the filter rack 100 and filter chassis 200 to be removed from the mounting rod 300, providing greater flexibility, reducing the difficulty of equipment production and assembly, and facilitating disassembly and maintenance.

[0045] Reference Figure 1 In some embodiments of the present invention, the mounting rod 300 includes a mounting section extending above the filter frame 100 and provided with external threads. This mounting section facilitates securing the mounting rod 300 to the filtration device for liquid filtration. Furthermore, the external threads, i.e., threaded mounting, facilitate both installation and removal, allowing for quick disassembly during maintenance.

[0046] Reference Figure 1In some embodiments of the present invention, the filter base 200 includes, from the inside out, a central panel 201 and an outer edge 202. The filter structure 203 is located only in the central panel 201, while the outer edge 202 is distributed around the peripheral edges of the central panel 201. Because the filter structure 203 is located only in the central panel 201, the outer edge 202 is a closed area without holes. Furthermore, the lower end of the filter frame 100 is connected to the boundary formed by the central panel 201 and the outer edge 202, so that the central panel 201 is enclosed by the filter frame 100 and the outer edge 202 is located outside the filter frame 100. With this structural arrangement, the outer edge 202 can be aligned with the inner wall of the filter device, ensuring that the liquid can only be discharged from the liquid outlet after passing through the filter frame 100 and the filter base 200, thereby improving the filtration effect.

[0047] Furthermore, the filter frame also includes a first filter cloth (not shown). The first filter cloth is laid on the filter frame 100, and the lower end of the first filter cloth extends to the outer edge area 202. In this way, the liquid medicine can only be discharged after passing through the first filter cloth, which can prevent the liquid medicine from passing through the side of the filter frame 100.

[0048] Furthermore, the filter frame includes a second filter cloth (not shown), which is mounted below the filter base 200 and extends from the periphery of the filter base 200 to the upper end surface of the outer edge area 202. The use of the second filter cloth can further improve the filtering effect, and installing it through the outer edge area 202 can avoid the presence of leaks and improve the filtering effect.

[0049] Furthermore, a sealing ring (not shown) is provided at the edge of the filter chassis 200. The sealing ring is used to abut against the inner wall of the filter device, which can further ensure the filtering effect and prevent the liquid from passing through the peripheral side to affect the filtering effect.

[0050] It is understood that the first filter cloth can be tapered, allowing it to be laid onto the outer surface of the filter frame 100, with its lower end positioned over the outer edge region 202. The second filter cloth is then fitted onto the filter base 200 from below, with its edge covering the upper surface of the outer edge region 202. During installation, the first filter cloth is kept covering the upper surface of the second filter cloth to avoid gaps. A sealing ring is then fitted over the edge of the filter base 200 to compress the first and second filter cloths, ensuring a tight seal at the edges and eliminating leaks.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
