Description

Technical Field

[0001] This utility model relates to the field of concentration device technology, and in particular to a concentration device for the preparation of traditional Chinese medicine materials. Background Technology

[0002] Concentration devices used in the preparation of Chinese medicinal materials are key equipment in the production process of Chinese medicine. Their function is to remove solvents from the extract, increase the concentration of active ingredients, and provide high-purity medicinal liquids or extracts for subsequent formulation processes.

[0003] Currently, when preparing concentrated Chinese medicinal materials, the solvent in the extract is vaporized by heating in a heating tank. The vapor is then condensed and recovered, allowing the medicinal liquid to be concentrated to the required concentration. After that, the concentrated medicinal liquid is discharged from the tank. However, some of the concentrated medicinal liquid remains on the residue inside the tank, making it difficult to effectively discharge it, resulting in a waste of the concentrated medicinal liquid.

[0004] To address the aforementioned problems, this utility model document proposes a concentration device for the preparation of traditional Chinese medicinal materials. Utility Model Content

[0005] This invention provides a concentration device for the preparation of Chinese medicinal materials, which solves the problem that in the prior art, some concentrated medicinal liquid remains on the dregs inside the tank, making it difficult to effectively discharge it from the tank and causing waste of concentrated medicinal liquid.

[0006] This utility model provides the following technical solution: A concentration device for the preparation of traditional Chinese medicinal materials includes: The base plate has a heating tank body fixedly mounted on its top via a support base. A matching tank cover is fixed to the opening of the heating tank body via a fastener. A drain pipe is connected to the bottom of the heating tank body. A ring frame is fixedly mounted on the inner wall of the heating tank body. A hollow basket for placing medicinal material packets is detachably mounted on the ring frame. The squeezing assembly, located on the tank lid, is used to squeeze the herb packets inside the perforated basket to reduce concentrate residue. A secondary filtration unit is installed on the drain pipe to further prevent the discharge of medicinal residue.

[0007] In one possible design, the ring frame is fixed to the top edge of the hollow basket by two bolts, and two positioning rods for quick alignment of threaded holes are symmetrically fixed at the bottom of the top edge of the hollow basket. The ring frame is provided with positioning holes for inserting the corresponding positioning rods.

[0008] In one possible design, the squeezing assembly includes an electric push rod fixedly installed at the center of the top of the can lid. The output end of the electric push rod slides through the inner wall of the can lid and is fixedly mounted with a squeezing disc. The bottom of the can lid is fixedly mounted with guide rods in a circular array to improve the stability of the squeezing disc movement. Multiple guide rods are slidably installed through the squeezing disc.

[0009] In one possible design, the secondary filtration assembly includes a hollow cap threaded to the bottom end of a drain pipe, the hollow cap containing a filter cloth for wrapping the opening of the drain pipe.

[0010] In one possible design, a mounting bracket is fixedly installed on the top of the base plate, and a vacuum pump and a condenser are fixedly installed on the mounting bracket. The input end of the vacuum pump is connected to the inner wall of the heating tank body through a suction pipe, and the output end of the vacuum pump is connected to the input end of the condenser through a first flexible hose. A collection tank for collecting condensate is placed on the top of the base plate, and the output end of the condenser is connected to the top cover of the collection tank through a second flexible hose.

[0011] In one possible design, the drain pipe is equipped with a corresponding drain valve.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0013] The working principle and usage process of this technical solution are as follows: Before use, use the positioning rod and positioning hole to quickly align the threaded holes of the ring frame and the hollow basket. Then, use two bolts to detachably fix the hollow basket to the ring frame. Put the medicine bag containing the medicine into the hollow basket. Fix the lid to the top of the heating tank body with the fastener. Thread the hollow cap to the bottom of the drain pipe and ensure that the filter cloth wraps the drain pipe opening. During use, the heating device is activated (though not explicitly mentioned, it is a conventional heating method) to heat the medicinal materials and extract in the heating tank, causing the solvent in the extract to vaporize. The vapor is then drawn out by the suction pump through the suction pipe and enters the condenser through the first hose. In the condenser, the vapor condenses into liquid and finally flows into the collection tank through the second hose, thus concentrating the medicinal liquid. Once the desired concentration is achieved, the electric push rod is activated. The output end of the electric push rod pushes the extrusion plate downward along the guide rod, ensuring stable movement of the extrusion plate. The extrusion plate squeezes the medicinal material package in the hollow basket, reducing the residue of the concentrated liquid on the dregs. Afterward, the drain valve is opened, and the concentrated medicinal liquid in the heating tank is discharged through the drain pipe. During the discharge process, the filter cloth inside the hollow cap wraps around the drain pipe opening, performing secondary filtration of the medicinal liquid and further preventing the discharge of dregs.

[0014] This utility model has the following beneficial effects: This invention uses a squeezing component to squeeze the herb packet, effectively squeezing out the concentrated liquid remaining in the herb residue. This avoids the waste caused by the difficulty in discharging this part of the liquid in traditional methods, and improves the utilization and recovery rate of the herb liquid. The secondary filtration component can further filter the herb residue, preventing it from being discharged with the concentrated liquid, ensuring the purity of the discharged liquid, and improving the quality of the concentrated Chinese herbal medicine liquid.

[0015] In this invention, the hollow basket and the ring frame are quickly aligned with the threaded hole through the positioning rod and positioning hole, and then fixed with bolts. This detachable design facilitates the placement and removal of the medicine package and improves operational efficiency.

[0016] The guide rod in the extrusion assembly of this invention ensures the stability of the extrusion disc during movement, making the extrusion process smoother, which is conducive to fully extruding the herbal medicine package and improving the extrusion effect. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted. Example 1

[0022] Please refer to Figure 1-4 Concentration device, including: The base plate 1 is used as the base plate. The heating tank body 2, model BIO-50L, is fixedly installed on the top of the base plate 1 via the support base 3. It is made of 316L medical-grade stainless steel, meets GMP standards, has strong corrosion resistance, is suitable for the environment of Chinese herbal medicine extracts, and has a dual mode of built-in electric heating tube (power 3kW) + jacketed steam heating. The temperature controllable range is 50-150℃, supporting precise temperature control. At the top of the heating tank body 2, the matching tank cover 4 is fixedly installed at the tank opening using fasteners to ensure that the tank cover 4 is sealed to the heating tank body 2 to prevent steam leakage during heating. At the bottom of the heating tank body 2, there is a drain pipe 5, and a corresponding drain valve 6 is set on the drain pipe 5 to control the discharge of the concentrate.

[0023] A ring frame 14 is welded to the middle of the inner wall of the heating tank body 2. The ring frame 14 is used to detachably set a hollow basket 15 for placing the herbal medicine bag. The hollow basket 15 is made of 304 stainless steel wire mesh. When placing the herbal medicine bag, the crushed Chinese herbal medicine is put into the non-woven fabric medicine bag and placed vertically into the hollow basket 15. The mesh structure of the hollow basket has a pore size (≤2mm) to ensure that the solvent can fully penetrate and to intercept large pieces of dregs, providing a basis for subsequent extrusion and filtration. The top edge of the ring frame 14 and the hollow basket 15 are fixed by two bolts 16. To facilitate quick alignment of the threaded holes, two positioning rods 17 are symmetrically fixed and welded to the bottom of the top edge of the hollow basket 15. At the same time, positioning holes 18 are provided on the ring frame 14 for inserting the corresponding positioning rods 17. During installation, the positioning rods 17 are first inserted into the positioning holes 18. Insert the positioning hole 18 to achieve initial positioning, and then use the bolt 16 to pass through the top edge of the hollow basket and lock it with the threaded hole of the ring frame to ensure that the medicine bag is stably suspended during the heating process, and at the same time facilitates quick disassembly and cleaning after use.

[0024] A mounting bracket 7 is fixedly installed on the top of the base plate 1. A vacuum pump 8 and a condenser 9 are fixedly installed on the mounting bracket 7. The vacuum pump 8 is a KNFN86KTE model, with a maximum pumping speed of 60L / min and a vacuum level of -95kPa, rapidly extracting steam from the tank. The pump head is made of PTFE+aluminum alloy, which is corrosion-resistant and suitable for steam containing volatile components of traditional Chinese medicine. The condenser 9 is a HP5-M10 model, made of 316L stainless steel, resistant to high temperatures (≤150℃) and corrosion by traditional Chinese medicine components. The input end of the vacuum pump 8 is connected to the inner wall of the heating tank body 2 via a suction pipe 10, and the output end of the vacuum pump 8 is connected to the input end of the condenser 9 via a first flexible hose 11. A collection tank 13 for collecting condensate is placed on the top of the base plate 1. The output end of the condenser 9 is connected to the top cover of the collection tank 13 via a second flexible hose 12. The top cover is equipped with a liquid level sensor, which automatically alarms when the liquid is full to prompt for replacement. During the heating and concentration of Chinese medicinal materials in the heating tank body 2, the vacuum pump 8 is started. The vacuum pump 8 extracts the steam generated in the heating tank body 2 through the suction pipe 10 and delivers it to the condenser 9 through the first hose 11. In the condenser 9, the steam is condensed into liquid water, i.e., condensate. The condensate flows into the collection tank 13 through the second hose 12 for collection, thereby realizing solvent recovery and concentration of the medicinal liquid. The condensate in the collection tank 13 can be reused for the next soaking of medicinal materials, realizing solvent recycling.

[0025] The squeezing assembly is located on the can lid 4 and is used to squeeze the herbal packets inside the hollow basket 15 to reduce the residue of the concentrate. An electric push rod 19, model SMC LEFS25, is fixedly installed at the center of the top of the can lid 4. It has a maximum thrust of 3000N (adjustable) to meet the squeezing requirements of the herbal packets, an IP66 protection rating to prevent liquid splashing, and supports operation in humid and hot environments. It also supports PLC control and can preset multiple squeezing programs (such as pulse squeezing). The output end of the electric push rod 19 slides through the inner wall of the can lid 4 and is fixedly mounted on the squeezing disc 20. The squeezing disc is made of food-grade silicone and its diameter is 5mm smaller than the inner diameter of the hollow basket to ensure sealed squeezing. To improve the stability of the squeezing disc 20, multiple guide rods 21 are fixedly arranged in a circular array at the bottom of the can lid 4. All guide rods 21 pass through the linear bearings of the squeezing disc 20 and are slidably mounted on it. When it is necessary to squeeze the herbal packets inside the hollow basket 15, the electric push rod 19 is activated. The output end pushes the extrusion plate 20 downward. Under the guidance of the guide rod 21, the extrusion plate 20 descends smoothly and squeezes the medicine bag in the hollow basket 15 to squeeze out the residual concentrated liquid in the medicine bag, thereby reducing the waste of concentrated liquid.

[0026] This application can be used for the concentration of medicinal liquids from Chinese medicinal materials, and can also be used in other fields applicable to this application. Example 2

[0027] Improvements based on Example 1: Concentration devices used in the preparation of Chinese medicinal materials, and their application in the field of concentration devices; Please refer to Figure 1 and 3 A secondary filtration component is installed on the drain pipe 5 to further prevent the discharge of medicinal residue. The secondary filtration component includes a hollow cap 22 that is threaded to the bottom end of the drain pipe 5. The hollow cap 22 contains a filter cloth 23 for wrapping the opening of the drain pipe 5. The filter cloth 23 has a double-layer structure, with an outer layer of 100-mesh nylon filter screen and an inner layer of ultra-fine fiber non-woven fabric. The porosity gradient design can intercept tiny particles (≥5μm). When the concentrate is discharged from the heating tank body 2, it passes through the drain pipe 5, and the filter cloth 23 performs secondary filtration on the concentrate, intercepting the fine medicinal residue that may be discharged with the concentrate in the hollow cap 22, thereby further ensuring the purity of the discharged concentrate and reducing the discharge of medicinal residue.
