Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine concentration technology, and in particular relates to a traditional Chinese medicine decoction concentration and filtration device. Background Technology

[0002] Extraction of traditional Chinese medicine (TCM) is the primary step in TCM manufacturing. During extraction, the extract needs to be continuously refluxed and concentrated to extract the essence. Filtration is then required to remove the residue. Current filtration devices for TCM extraction are complex, especially for small-batch decoction and concentration operations. These devices are expensive, inflexible, and uneconomical. Simpler filtration devices, on the other hand, directly pass the liquid through the filter. After a period of use, the filter pores easily become clogged with residue and other impurities, making cleaning and replacement cumbersome and affecting filtration efficiency, which in turn impacts the concentration efficiency of the TCM liquid. Therefore, it is necessary to improve existing filtration devices to address these shortcomings. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a traditional Chinese medicine decoction concentration and filtration device.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A traditional Chinese medicine decoction concentration and filtration device includes a conical funnel body. The upper end of the funnel body has, from bottom to top, a three-stage filter mounting platform, a two-stage filter mounting platform, and a primary filter mounting platform. A limiting protrusion is provided around the primary filter mounting platform. A three-stage filter assembly is detachably mounted on the three-stage filter mounting platform, a two-stage filter assembly is detachably mounted on the two-stage filter mounting platform, and a primary filter assembly is detachably mounted on the primary filter mounting platform. Each filter assembly includes a mounting frame and a filter fixed within the mounting frame. The mesh diameter of each filter is arranged in descending order: the primary filter assembly's filter, the two-stage filter assembly's filter, and the tertiary filter assembly's filter. A positioning post is provided on the lower side of the mounting frame of each filter assembly, and positioning holes matching the positioning posts are provided on the mounting platform. The funnel body includes an upper conical section and a lower cylindrical section, with the minimum outer diameter of the conical section being larger than the outer diameter of the cylindrical section. A positioning platform is formed at the junction of the two sections.

[0006] Furthermore, the filters in each stage of the filter assembly are all net-shaped. The lower end of the filter in the primary filter assembly extends into the filter in the secondary filter assembly, and the lower end of the filter in the secondary filter assembly extends into the filter in the tertiary filter assembly. There are gaps between the filters in the primary filter assembly and the secondary filter assembly, and between the filters in the secondary filter assembly and the tertiary filter assembly.

[0007] Furthermore, each stage of the filter assembly has 2-5 symmetrical positioning posts on the lower side of its mounting frame.

[0008] Furthermore, each positioning post is evenly distributed along the circumference of the corresponding mounting frame.

[0009] Furthermore, each stage of the filter assembly has symmetrical handles on the upper side of its mounting frame, and the height of the handles is less than the height difference between two adjacent mounting platforms.

[0010] Furthermore, the total length of the column segment is 3-10mm.

[0011] Furthermore, the limiting protrusion is symmetrically provided with funnel-shaped handles.

[0012] Furthermore, the length of the positioning post is 1.5-3mm.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] This invention features a reasonable structural design. In use, the funnel body can be directly inserted into the container opening, and the medicine can be poured directly into the funnel body. The mesh diameter of the filter screens in each stage of the filter screen assembly decreases from top to bottom, so the medicine will be filtered step by step through each stage of the filter screen assembly. The filter screen is not easy to clog, the filtration effect is good, and the filtration efficiency is guaranteed. This filtration device is suitable for small-batch production. It only requires periodic removal of the filter screen for cleaning or replacement. It is easy to operate, low in cost, and can work stably and for a long time. Attached Figure Description

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A device for decocting, concentrating, and filtering traditional Chinese medicine, such as Figures 1 to 5 As shown, it includes a cone-shaped funnel body 1. The upper end of the funnel body is provided with a three-stage filter mounting platform 2, a two-stage filter mounting platform 3, and a primary filter mounting platform 4 from bottom to top. A limiting protrusion 5 is provided around the primary filter mounting platform. A three-stage filter assembly 6 is detachably installed on the three-stage filter mounting platform, a two-stage filter assembly 7 is detachably installed on the two-stage filter mounting platform, and a primary filter assembly 8 is detachably installed on the primary filter mounting platform.

[0026] Each stage of the filter assembly includes a mounting frame and a filter fixed within the mounting frame. Specifically, the three-stage filter assembly includes a three-stage filter mounting frame 9 and a three-stage filter 10 fixed within the mounting frame; the two-stage filter assembly includes a two-stage filter mounting frame and a two-stage filter fixed within the mounting frame; and the primary filter assembly includes a primary filter mounting frame and a primary filter fixed within the mounting frame. In an optional embodiment, the funnel body includes an upper conical segment 11 and a lower cylindrical segment 12, with the minimum outer diameter of the conical segment being larger than the outer diameter of the cylindrical segment. A positioning platform 13 is formed at the junction of the two segments. If necessary, the cylindrical segment can be inserted into the container opening, and the positioning platform provides excellent positioning.

[0027] The mesh diameters of the filters, from largest to smallest, are: primary filter, secondary filter, and tertiary filter. This means that after the primary filter performs coarse filtration, the secondary and tertiary filters are applied. This not only improves the filtration efficiency but also ensures longer-lasting filtration performance due to the optimized mesh diameter configuration of each filter. Each filter assembly has a positioning post 14 on the underside of its mounting frame, and a corresponding positioning hole on the mounting platform. During installation, simply insert the positioning post at the bottom of the mounting frame into the corresponding positioning hole on the mounting platform to maintain the stability of the filter assembly. Since the outer diameters of the filters are different, installation errors are prevented.

[0028] The filters in each stage of the filter assembly are all net-shaped. The lower end of the filter in the primary filter assembly extends into the filter in the secondary filter assembly, and the lower end of the filter in the secondary filter assembly extends into the filter in the tertiary filter assembly. There are gaps between the filters in the primary filter assembly and the secondary filter assembly, and between the filters in the secondary filter assembly and the tertiary filter assembly.

[0029] Typically, 2-5 positioning posts are symmetrically arranged on the lower side of the mounting frame of each stage of the filter assembly. The positioning posts are evenly distributed along the circumference of the corresponding mounting frame. Funnel-shaped handles 15 are symmetrically arranged on the limiting protrusions. Mounting frame handles 16 are symmetrically arranged on the upper side of the mounting frame of each stage of the filter assembly. The height of the handles is less than the height difference between two adjacent mounting platforms, and the handles on the mounting frame do not interfere with other components. For example, the total length of the column segment is 3-10mm. The length of the positioning post is 1.5-3mm. The funnel-shaped handles allow for easy lifting of the entire filter device. During disassembly or installation, the funnel-shaped handles provide a convenient grip. The mounting frame handles allow for easy lifting of the filter assembly, facilitating installation or removal for cleaning.

[0030] This invention features a reasonable structural design. In use, the funnel body can be directly inserted into the container opening, and the medicine can be poured directly into the funnel body. The mesh diameter of the filter screens in each stage of the filter screen assembly decreases from top to bottom, so the medicine will be filtered step by step through each stage of the filter screen assembly. The filter screen is not easy to clog, the filtration effect is good, and the filtration efficiency is guaranteed. This filtration device is suitable for small-batch production. It only requires periodic removal of the filter screen for cleaning or replacement. It is easy to operate, low in cost, and can work stably and for a long time.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
