The key technical features include an extraction tank with a filter screen barrel fixedly connected to its bottom. A homogenizing mixing mechanism is movably connected to the inner side of the extraction tank, and a dynamic filtration mechanism is movably connected to the inner side of the filter screen barrel. This mechanism can dynamically adjust the pore size to adapt to different raw material filtration needs through the contact and rotation of a first and second circular hole screen.

In recent years, its application technology in food additives, pharmaceutical research and development, cosmetics and other fields has made continuous breakthroughs. For example, the stability can be improved through nano-encapsulation, making it a hot topic in the research of functional natural ingredients.

[0003] In existing technologies, traditional curcumin active separation and filtration equipment suffers from insufficient homogenization of solid-liquid mixing due to the use of a single stirring mode and limited mixing position. At the same time, the fixed pore size filtration design lacks dynamic adjustment and self-cleaning functions, resulting in poor filtration adaptability and easy clogging.

[0004] To address this, a filtration device for separating curcumin from its active ingredients is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for separating curcumin from active ingredients, which can solve the problems of insufficient homogenization of solid-liquid mixing caused by the existing single stirring mode and limited mixing position, as well as the lack of dynamic adjustment and self-cleaning function in the fixed pore size filtration design.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for separating curcumin from active ingredients, comprising an extraction tank, a filter screen barrel fixedly connected to the bottom of the extraction tank, a homogenizing mixing mechanism movably connected to the inner side of the extraction tank, and a dynamic filtration mechanism movably connected to the inner side of the filter screen barrel.

[0007] The dynamic filtration mechanism includes a support ring fixedly connected to the inside of the filter screen barrel. A telescopic support column is fixedly connected to the top of the support ring. A compression spring is fixedly connected to the inside of the telescopic support column. A first circular hole screen is fixedly connected to the top of the telescopic support column. A servo motor is fixedly connected to the bottom of the first circular hole screen.

[0008] Preferably, the homogenizing mixing mechanism includes a stepper motor fixedly connected to the inside of the extraction tank, and the output end of the stepper motor is fixedly connected to a supporting spindle.

[0009] Preferably, support rods are rotatably connected to the top and bottom of the outer side of the support main shaft, and a drive motor is fixedly connected to the side of the support rod away from the support main shaft. A mixing blade is fixedly connected to the output end of the drive motor.

[0010] Preferably, each of the two support rods is slidably connected to an adjusting slider on its opposite side, and the two adjusting sliders are rotatably connected to an adjusting rod on their opposite sides. An electronic telescopic rod is fixedly connected to the side of the adjusting rod closest to the main support shaft, and the electronic telescopic rod is fixedly connected to the outside of the main support shaft.

[0011] Preferably, the filter residue crushing assembly includes an extension shaft fixedly connected to the top of the second circular screen, and a crushing blade is rotatably connected to the top of the extension shaft.

[0012] Preferably, a torsion spring is fixedly connected to the bottom of the crushing blade, and the torsion spring is fixedly connected to the top of the second circular hole screen.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting a dynamic filtration mechanism, can dynamically adjust the filtration aperture size to adapt to the filtration needs of different raw materials through the close rotation of the first and second circular hole screens. At the same time, the spring rebound drives the first and second circular hole screens to vibrate and accelerate solid-liquid separation. After filtration, the servo motor drives the crushing blades to rotate at high speed. With the help of centrifugal force and torsion spring, the blades rotate in the opposite direction to crush the residual filter residue. Combined with the vibration of the telescopic support column to assist in the discharge of residue, it not only realizes the dynamic adjustment of the filtration aperture, but also completes self-cleaning through the dual action of crushing and vibration. It effectively solves the problems of poor filtration adaptability and easy clogging caused by the inability to flexibly adjust the aperture and lack of self-cleaning function in fixed aperture filtration devices.

[0019] 2. This application, by setting up a homogenizing mixing mechanism, can drive the support main shaft through a stepper motor to rotate the mixing blades, and in conjunction with a drive motor to make the mixing blades rotate, and with the help of an electronic telescopic rod to reciprocate and adjust the angle of the support rod, form a composite stirring mode that combines a large circumference and a self-centered circle. This can dynamically cover different areas of the extraction tank, so that the solid-liquid mixture tends to a homogeneous state under the multiple stirring effects of revolution, rotation and angle change. This effectively solves the problem of insufficient homogenization of solid-liquid mixing caused by the single stirring mode and limited mixing position of traditional equipment, which not only improves the extraction efficiency, but also provides a good homogenization foundation for subsequent filtration operations.

[0026] 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.

[0027] Please see Figure 1-5The present invention provides the following technical solution:

[0028] A filtration device for separating curcumin from active ingredients includes an extraction tank 1, a filter screen 2 fixedly connected to the bottom of the extraction tank 1, a homogenizing mixing mechanism 3 movably connected to the inside of the extraction tank 1, and a dynamic filtration mechanism 4 movably connected to the inside of the filter screen 2.

[0029] The dynamic filtration mechanism 4 includes a support ring 41 fixedly connected to the inside of the filter screen barrel 2. A telescopic support column 42 is fixedly connected to the top of the support ring 41. A compression spring 43 is fixedly connected to the inside of the telescopic support column 42. A first circular hole screen 44 is fixedly connected to the top of the telescopic support column 42. A servo motor 45 is fixedly connected to the bottom of the first circular hole screen 44. A second circular hole screen 46 is fixedly connected to the output end of the servo motor 45. A filter residue crushing assembly 47 is movably connected to the top of the second circular hole screen 46.

[0030] In this embodiment: when separating the active ingredient of curcumin, curcumin and its root, stem, and leaf powders are first poured into the extraction tank 1 and mixed with the extraction liquid to obtain a solid-liquid mixture composed of an active liquid phase and waste residue. Then, the regulating valve 8 inside the transition pipe 7 is opened to discharge the solid-liquid mixture into the guide hood. After being guided, the solid-liquid mixture impacts the bottom filter structure composed of the first circular hole sieve 44 and the second circular hole sieve 46 under the action of gravity, causing it to press down to reduce the distance between the first circular hole sieve 44 and the support ring 41 and to press the telescopic support 42 and the inner compression spring 4 between them. 3. After the compression spring 43 accumulates enough elastic potential energy, it rebounds and drives the first round hole screen 44 and the second round hole screen 46 to vibrate and filter. At the same time, in order to adapt to different filtration needs, the servo motor 45 at the bottom of the first round hole screen 44 can be started to drive the second round hole screen 46, which is only connected to its output end and matches the top of the first round hole screen 44, to rotate as a whole. The aperture is adjusted from large to small by the mutual blocking of the matching apertures of the two. When they match again, the maximum aperture is restored. Finally, the filter residue crushing component 47 is used to crush the top waste residue and discharge it through the bottom discharge port 6 under slight vibration.

[0031] Specifically, such as Figure 2 , Figure 4 As shown, the homogenizing mixing mechanism 3 includes a stepper motor 31 fixedly connected to the inside of the extraction tank 1, and a supporting spindle 32 is fixedly connected to the output end of the stepper motor 31.

[0032] Specifically, such as Figure 2 , Figure 4 As shown, support rods 33 are rotatably connected to the top and bottom of the outer side of the support main shaft 32. A drive motor 34 is fixedly connected to the side of the support rod 33 away from the support main shaft 32. A mixing blade 35 is fixedly connected to the output end of the drive motor 34.

[0033] Specifically, such as Figure 2 , Figure 4As shown, each of the two support rods 33 is slidably connected to an adjusting slider 36 on its opposite side. The two adjusting sliders 36 are rotatably connected to an adjusting rod 37 on their opposite sides. An electronic telescopic rod 38 is fixedly connected to the side of the adjusting rod 37 near the support main shaft 32. The electronic telescopic rod 38 is fixedly connected to the outside of the support main shaft 32.

[0034] In this embodiment: During the extraction operation, the stepper motor 31 located at the bottom of the extraction tank 1 is activated, causing the support shaft 32 at its output end, located at the center of the extraction tank 1, to rotate, thus achieving shaft rotation. Simultaneously, two sets of support rods 33 on the outer side of the support shaft 32 are rotatably connected, and a mixing blade 35 driven by a drive motor 34 is mounted on them. The mixing blade 35 rotates on its own axis while cooperating with the rotation of the shaft center. In addition, during the mixing process, the electronic telescopic rod 38 on the outer side of the support shaft 32 is activated. When it retracts, it drives the adjustment rod 37 supported at the other end to move towards the support shaft 32. When the adjustment rod 37 moves from the side with the larger angle between the two support rods 33 to the side with the smaller angle, it rotates on the adjustment slider 36 on the outer side of the two support rods 33 and pulls the adjustment slider 36 to move towards the side with the smaller angle, causing the two support rods 33 to rotate to both sides. Under the reciprocating action of the electronic telescopic rod 38, a reciprocating inward and outward stirring mode is formed, which combines large circumference and self-centering, thereby promoting the extraction operation and making the solid-liquid mixture tend to be homogenized for subsequent filtration.

[0035] Specifically, such as Figure 3 As shown, the filter residue crushing assembly 47 includes an extension shaft 47a fixedly connected to the top of the second circular hole screen 46, and a crushing blade 47b is rotatably connected to the top of the extension shaft 47a.

[0036] Specifically, such as Figure 3 As shown, a torsion spring 47c is fixedly connected to the bottom of the crushing blade 47b, and the torsion spring 47c is fixedly connected to the top of the second circular hole screen 46.

[0037] In this embodiment: A crushing blade 47b is rotatably connected to the top of an extension shaft 47a that rotates coaxially with the second circular hole screen 46, and a torsion spring 47c is provided between the two rotation points. During normal adjustment, the crushing blade 47b rotates slowly following the hole diameter adjustment and does not play a role. When the filtration operation is completed and filter residue remains on the top of the second circular hole screen 46, the servo motor 45 speed increases and drives the first circular hole screen 44 to rotate at high speed. At this time, the crushing blade 47b rotates along the center of the extension shaft 47a by centrifugal force. After tightening the torsion spring 47c, it rotates in the opposite direction. At the same time, this high-speed rotation will affect the contraction of the telescopic support column 42 to achieve a small amplitude vibration, thereby crushing the top waste residue and discharging it through the bottom discharge port 6 under small vibration.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, the top of the extraction tank 1 is fixedly connected to the inlet 5.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, a discharge port 6 is fixedly connected to the bottom of the filter screen barrel 2.

[0040] In this embodiment, feeding and discharging can be achieved through the inlet 5 and the outlet 6.

[0041] Specifically, such as Figure 2 As shown, the bottom of the extraction tank 1 is fixedly connected to the transition pipe 7, and the inner side of the transition pipe 7 is fixedly connected to the regulating valve 8.

[0042] Specifically, such as Figure 2 As shown, a guide cover 9 is fixedly connected to the bottom of the extraction tank 1, and a transition tube 7 is set inside the guide cover 9.

[0043] In this example: the solid-liquid mixture in the extraction tank 1 can be transferred to the screening tank through the transition pipe 7, the flow rate into the transition pipe 7 can be adjusted by the regulating valve 8, and the guide cover 9 can converge and guide the liquid.

[0044] Working Principle: When separating the active ingredient of curcumin, the curcumin and its root, stem, and leaf powders are poured into extraction tank 1 and mixed with the corresponding extraction liquid to separate the waste from the active ingredient. The active ingredient and waste are separated into a liquid phase and flocculent impurities. In this process, existing technologies typically use stirring blades to promote mixing and improve extraction efficiency. However, existing technologies usually employ a single mixing mode with limited mixing location, resulting in low efficiency and difficulty in achieving a homogeneous solid-liquid mixture within extraction tank 1, which also affects subsequent filtration. Therefore, to avoid these issues, a single-mode stirring blade is no longer used. Instead, during the extraction process, a stepper motor 31 located at the bottom of extraction tank 1 is activated, allowing... The support shaft 32, located at the output end of the stepper motor 31 and at the center of the extraction tank 1, rotates, thereby achieving shaft rotation. Two sets of rotatably connected support rods 33 are respectively arranged on the upper and lower sides of the support shaft 32. A mixing blade 35 driven by a drive motor 34 is mounted on the outer side of each support rod 33. The mixing blade 35 rotates around the support point of the support rod 33 while rotating in conjunction with the rotation of the shaft's center, thus optimizing the mixing mode. Furthermore, during the mixing process, an electronic telescopic rod 38 located on the outer side of the support shaft 32 can be activated simultaneously. When the electronic telescopic rod 38 retracts, it drives the adjusting rod 37 supported at the other end to move towards the support shaft, while the overall length of the adjusting rod 37 remains unchanged. It moves from the side with the larger angle formed by the two support rods 33 towards... When the smaller side moves, it simultaneously compresses both support rods 33. The adjusting rod 37 rotates on the adjusting slider 36 outside the two support rods 33 and pulls the adjusting slider 36 to move towards the side with the smaller angle, thereby causing the two support rods 33 to rotate to both sides. Under the reciprocating action of the electronic telescopic rod 38, a reciprocating inward and outward stirring mode with large circumference and self-centering is formed, thus promoting the extraction operation and homogenizing it to facilitate subsequent filtration. After extraction is completed, it is in a solid-liquid mixed phase state of active liquid phase and waste residue. By opening the adjusting valve 8 inside the transition pipe 7, the solid-liquid mixed phase inside the extraction tank 1 is discharged into the guide hood, and the liquid is guided to form a stream, thereby converging and accelerating the discharge. At this speed, the solid-liquid mixture, under the acceleration of gravity, impacts the filter structure at the bottom, composed of the first perforated screen 44 and the second perforated screen 46, causing it to press down as a whole. This reduces the distance between the first perforated screen 44 and the support ring 41, and simultaneously compresses the telescopic support 42 between it and the support ring 41 and its inner compression spring 43. After sufficient elastic potential energy is maintained, the compression spring 43 rebounds and drives the first perforated screen 44 and the second perforated screen 46 to perform a vibration filtration effect. To adapt to different filtration stages and filtration requirements under different raw material conditions, the filter aperture can be adjusted. Initially, the discharge apertures of the first perforated screen 44 and the second perforated screen 46 are consistent and fit together. When the servo motor 45 at the bottom of the first perforated screen 44 is started...It can rotate the second circular hole screen 46, which is only connected to the output end of the servo motor 45 but matches the top of the first circular hole screen 44, and make the matching hole diameters block each other, thus achieving a process from large to small. After they match again, they return to the maximum hole diameter state. In summary, it can meet the needs of different filtration sizes. In addition, an extension shaft 47a is coaxially connected to the second circular hole screen 46, and a crushing blade 47b is rotatably connected to the top of the extension shaft 47a. A torsion spring 47c is set between the top of the extension shaft 47a and the rotation point of the extension shaft 47a. During normal adjustment, the crushing blade 47b follows the hole. The slow rotation of the diameter adjustment mechanism is ineffective. However, when the filtration process is complete and filter residue remains at the top of the second circular screen 46, the servo motor 45 speeds up, driving the first circular screen 44 to rotate at high speed. At this time, the crushing blade 47b rotates along the center of the extension shaft 47a due to centrifugal force, and then rotates in the opposite direction after tightening the torsion spring 47c. This high-speed rotation also affects the contraction of the telescopic support 42, causing a small-amplitude vibration. This crushes the top waste residue, which is then discharged through the bottom discharge port 6 under slight vibration. In summary, this optimizes both the extraction and mixing stages of the filtration device for separating curcumin and active ingredients.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
