Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical component extraction equipment, specifically to a high-efficiency extraction tank for effective pharmaceutical components. Background Technology

[0002] In the production of traditional Chinese medicine or natural medicines, the extraction of active medicinal components is a crucial step, and its extraction efficiency and purity directly affect the quality and efficacy of the medicine. Traditional methods of extracting active medicinal components often employ single-function equipment in a step-by-step manner. For example, the medicinal materials are first crushed using a pulverizer, then transferred to an extraction tank for soaking, decoction, and other extraction operations, and finally the residue and extract are separated by filtration equipment.

[0003] This step-by-step processing method has many drawbacks: First, the intermediate transfer links are cumbersome, which not only consumes a lot of manpower and time, but also easily leads to material loss and reduces extraction efficiency; Second, the connection and coordination between different devices is not good, making it difficult to ensure the continuity and stability of the entire extraction process, making it difficult to achieve the ideal extraction rate of effective components; Third, the traditional equipment has a relatively simple structure, and the medicinal materials are not sufficiently pulverized, resulting in a limited contact area between the medicinal materials and the solvent, making it difficult to fully release the effective components during extraction. At the same time, the filtration and separation effect is poor, and there is a lot of residue, which affects the purity of the extract.

[0004] In view of this, we propose a high-efficiency extraction vessel for medicinal active ingredients. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-efficiency extraction vessel for medicinal active ingredients.

[0006] The technical solution of this utility model is:

[0007] A high-efficiency extraction vessel for medicinal active ingredients includes a vertically mounted U-shaped support frame. A pulverizing tank is fixedly connected to the top of the U-shaped support frame. A pressing box, communicating with the bottom of the pulverizing tank, is installed. A filter box, communicating with the bottom of the pressing box, is installed. A pulverizing shaft is rotatably mounted inside the pulverizing tank. Several evenly distributed pulverizing blades are fixedly mounted on the outer circumference of the pulverizing shaft. A pulverizing motor with an output shaft coaxially fixed to the pulverizing shaft is mounted on the top of the pulverizing tank. Two feeding hoppers are symmetrically mounted on the top of the pulverizing tank, each with a feeding valve. Four sets of pressing rollers, arranged vertically and staggered, are installed inside the pressing box, with two rollers in each set. A drive assembly for driving the pressing rollers in the same direction is installed outside the pressing box. At least one retractable filter frame is installed inside the filter box. By integrating the pulverizing tank, pressing box, and filter box onto the U-shaped support frame, an integrated extraction process is formed, enabling continuous processing of medicinal materials from pulverization to pressing to filtration, reducing intermediate transfer links, and improving extraction efficiency. Driven by a pulverizing motor, the pulverizing blades thoroughly pulverize the medicinal materials, increasing the contact area between the materials and the solvent. Four sets of staggered extrusion rollers further compress the pulverized materials, promoting the release of active ingredients. The removable filter frame facilitates quick filtration and separation of dregs and extract. The overall structure is compact and easy to operate, significantly improving the extraction efficiency and purity of active medicinal ingredients.

[0008] As a preferred technical solution, the U-shaped support frame has two symmetrically integrally formed diagonal braces inside. The two diagonal braces on the U-shaped support frame, through their integral forming design, can effectively enhance the structural strength and stability of the support frame and distribute the weight load of the crushing tank, extrusion box, and filter box.

[0009] As a preferred technical solution, a first guide block is fixed near the bottom inside the pulverizing tank. Two baffles are symmetrically slidably installed inside the discharge port at the bottom of the first guide block, and a placement groove for placing the baffles is opened on the inner wall of the discharge port. The first guide block inside the pulverizing tank can guide the pulverized medicinal materials to gather towards the discharge port, making it easier for them to enter the extrusion chamber in a concentrated manner; the two slidably installed baffles can control the opening and closing of the discharge port through the placement groove.

[0010] As a preferred technical solution, a double-threaded screw is rotatably installed inside the placement slot. The double-threaded screw is threadedly connected to both baffles. An adjusting motor with an output shaft coaxially fixed to the double-threaded screw is installed on the outer wall of the crushing tank. The threaded connection between the double-threaded screw and the two baffles, in conjunction with the adjusting motor, enables the synchronous reverse movement of the two baffles, precisely controlling the opening and closing size of the discharge port.

[0011] As a preferred technical solution, two support blocks are fixedly installed at the bottom of each filter frame inside the filter box. The support blocks provide stable support for the filter frames.

[0012] As a preferred technical solution, a second guide block is installed at the bottom of the filter box, and a discharge pipe is installed at the bottom of the second guide block. A discharge valve is installed on the discharge pipe. The second guide block at the bottom of the filter box can guide the filtered extract to converge into the discharge pipe, avoiding residue of the extract in the filter box and improving the collection rate of the extract.

[0013] As a preferred technical solution, an outer plate is fixedly installed on the outer wall of the filter frame, and a handle is fixed on the outer plate. The design of the outer plate and handle on the outer wall of the filter frame facilitates the operator to hold the handle and pull the filter frame out of or into the filter box.

[0014] As a preferred technical solution, the drive assembly includes driven gears coaxially fixed to several extrusion rollers, and two driven gears connected to the same set of extrusion rollers meshing with each other. The drive assembly also includes a mounting plate fixed to the outer wall of the extrusion chamber, on which a grinding motor is fixed. A drive gear is coaxially fixed to the output shaft of the grinding motor. The drive gear meshes with the driven gear located above it and a connecting gear is provided between the drive gear and the driven gear located below it. The connecting gear meshes with both of them and rotates on the outer wall of the extrusion chamber. The drive assembly achieves synchronous drive of multiple sets of extrusion rollers by the grinding motor through the meshing transmission of the drive gear, connecting gear, and driven gear, ensuring that the upper and lower interleaved extrusion rollers rotate and effectively extrude the medicinal materials.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By integrating the pulverizing tank, extrusion chamber, and filtration chamber onto a U-shaped support frame, an integrated extraction process is formed, enabling continuous processing of medicinal materials from pulverization to extrusion to filtration. This reduces intermediate transfer steps and improves extraction efficiency. The pulverizing blades, driven by a pulverizing motor, thoroughly pulverize the medicinal materials, increasing the contact area between the materials and the solvent. Four sets of staggered extrusion rollers further compress the pulverized materials, promoting the release of active ingredients. The removable filter frame facilitates quick and easy filtration to separate the residue from the extract. The overall structure is compact, easy to operate, and significantly improves the extraction efficiency and purity of the medicinal active ingredients. Attached Figure Description

[0026] Please see Figures 1-5 This utility model provides a technical solution:

A drive assembly 5 for driving the several extrusion rollers 30 located in the same direction to rotate is installed outside the extrusion box 3. At least one retractable filter frame 40 is installed inside the filter box 4. By integrating the pulverizing tank 2, the extrusion box 3, and the filter box 4 onto the U-shaped support frame 1, an integrated extraction process is formed, realizing continuous processing of medicinal materials from pulverization to extrusion to filtration, reducing intermediate transfer links and improving extraction efficiency. The pulverizing blades 25, driven by the pulverizing motor 22, thoroughly pulverize the medicinal materials, increasing the contact area between the materials and the solvent; four sets of staggered extrusion rollers 30 further extrude the pulverized materials, promoting the release of active ingredients; the removable filter frame 40 facilitates rapid filtration and separation of residue and extract. The overall structure is compact, easy to operate, and significantly improves the extraction efficiency and purity of the active medicinal ingredients.

[0028] As a preferred embodiment, the U-shaped support frame 1 has two symmetrically integrally formed inclined bracing plates 10 inside. The two inclined bracing plates 10 on the U-shaped support frame 1, through the integral forming design, can effectively enhance the structural strength and stability of the support frame and disperse the weight load of the crushing tank 2, the extrusion box 3 and the filter box 4.

[0029] In a preferred embodiment, a first guide block 26 is fixed near the bottom inside the pulverizing tank 2. Two baffles 28 are symmetrically slidably installed inside the discharge port 27 at the bottom of the first guide block 26, and a placement groove for placing the baffles 28 is provided on the inner wall of the discharge port 27. The first guide block 26 inside the pulverizing tank 2 can guide the pulverized medicinal materials to gather towards the discharge port 27, making it easier for them to enter the extrusion box 3. The two slidably installed baffles 28 can control the opening and closing of the discharge port 27 through the placement groove.

[0030] In a preferred embodiment, a double-threaded screw 29 is rotatably installed inside the placement slot. The double-threaded screw 29 is threadedly connected to both baffles 28. An adjusting motor 23, with its output shaft coaxially fixed to the double-threaded screw 29, is installed on the outer wall of the crushing tank 2. The threaded connection between the double-threaded screw 29 and the two baffles 28, in conjunction with the adjusting motor 23, enables the synchronous reverse movement of the two baffles 28, precisely controlling the opening and closing size of the discharge port 27.

[0031] As a preferred embodiment, two support blocks 41 are fixedly installed inside the filter box 4 at the bottom of each filter frame 40. The support blocks 41 provide stable support for the filter frame 40.

[0033] In a preferred embodiment, an outer plate 400 is fixedly installed on the outer wall of the filter frame 40, and a handle 401 is fixedly installed on the outer plate 400. The design of the outer plate 400 and the handle 401 on the outer wall of the filter frame 40 makes it convenient for the operator to hold the handle 401 to pull the filter frame 40 out of or into the filter box 4.

[0034] In a preferred embodiment, the drive assembly 5 includes driven gears 50 coaxially fixed to several extrusion rollers 30, and two driven gears 50 connected to the same group of extrusion rollers 30 mesh with each other. The drive assembly 5 also includes a mounting plate 53 fixed to the outer wall of the extrusion chamber 3. A grinding motor 54 is fixed on the mounting plate 53. A drive gear 51 is coaxially fixed to the output shaft of the grinding motor 54. The drive gear 51 meshes with the driven gear 50 located above it and a connecting gear 52 is provided between the drive gear 51 and the driven gear 50 located below it. The connecting gear 52 meshes with both of them and rotates on the outer wall of the extrusion chamber 3. The drive assembly 5 achieves synchronous drive of the grinding motor 54 to multiple groups of extrusion rollers 30 through the meshing transmission of the drive gear 51, the connecting gear 52 and the driven gears 50, ensuring that the extrusion rollers 30 rotate in an alternating manner and effectively extrude the medicinal materials.

[0035] This utility model discloses a high-efficiency extraction tank for pharmaceutical active ingredients. In use, it follows the integrated continuous processing principle of "crushing-extrusion-filtration," and the specific process is as follows:

[0036] First, the operator adds the medicinal materials through the two feeding hoppers 20 at the top of the pulverizing tank 2, and the amount of material added at one time can be controlled by the feeding valve 21. After starting the pulverizing motor 22, its output shaft drives the pulverizing shaft 24 and the pulverizing blades 25 on the outer circumference to rotate at high speed, which fully pulverizes the added medicinal materials, increases the contact area between the medicinal materials and the subsequent solvent, and lays the foundation for the release of effective ingredients.

[0037] After pulverization, the regulating motor 23 is started, and its output shaft drives the double threaded screw 29 to rotate, causing the two baffles 28 to slide synchronously in opposite directions along the placement groove, opening the discharge port 27 at the bottom of the first guide block 26. Under the guidance of the first guide block 26, the pulverized medicinal materials are concentrated into the extrusion chamber 3 below.

[0038] After the medicinal materials enter the extrusion chamber 3, the drive assembly 5 begins to operate: the grinding motor 54 drives four sets of alternating extrusion rollers 30 to rotate synchronously in opposite directions through the meshing of the drive gear 51, connecting gear 52, and driven gear 50. Under the action of gravity, the medicinal materials pass through each set of extrusion rollers 30 in sequence, receiving continuous and uniform extrusion, which promotes cell rupture and further releases the active ingredients, while also fully mixing with any solvents that may be added.

[0039] The mixture (containing medicinal residue and extract) after extrusion processing enters the filter box 4 and is filtered and separated by at least one filter frame 40. The filter frame 40 is stably supported by a support block 41 at the bottom, and an outer plate 400 ensures that it is installed in place. The medicinal residue is trapped inside the filter frame 40, while the extract flows downward through the filter layer. Guided by the second feed block 42, the extract converges to the discharge pipe 43, and the operator can control the discharge and collection of the extract through the discharge valve 44.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
