Description

Technical Field

[0001] This invention relates to the field of feed processing, specifically to equipment for extracting active ingredients from plant extract additives used in veterinary feed processing. Background Technology

[0002] In veterinary feed processing, traditional extraction methods mainly involve placing plant materials in an extraction tank for steaming or boiling. Heating dissolves the active ingredients, and then filtering to remove residue to obtain the extract. However, relying solely on steaming or boiling makes it difficult to completely rupture plant cell walls, thus failing to effectively extract the active ingredients attached to the residue. This results in insufficient release of active ingredients and a low extraction rate.

[0003] The currently published Chinese patent announcement number CN118179086B discloses an extraction device and method for extracting active ingredients from plants, including an extraction chamber and a crushing component. This patent uses the crushing component to crush the plant, disrupting the plant cell structure and promoting the dissolution of active ingredients. However, the pressure applied to the plant may be unevenly distributed, resulting in some areas of plant residue being fully crushed while other areas fail to effectively break down cell walls, affecting the release of active ingredients and thus reducing the extraction rate.

[0004] The currently publicly available Chinese patent application, CN116422048B, discloses a plant powder separation device and its usage method. The device includes a pressure plate with uniformly distributed through-holes on its top surface for the flow of a mixed liquid. An adjustment component is installed inside each through-hole to adjust its opening size. This patent, by adaptively adjusting the inner diameter of the through-holes, can adjust the pressure exerted by the pressure plate on the liquid located below or above the pressure plate during its vertical movement. This prevents excessive pressure from the pressure plate causing liquid to enter clogged filter holes and compress solids. Although the pressure applied to the plant is regulated, even with the through-hole size adjustment mechanism, uneven distribution of plant residue within the separation tank can still lead to localized excessive or insufficient pressure.

[0005] According to the two patents mentioned above, there is a need for an extraction device that can ensure uniform pressure distribution, efficiently disrupt plant cell structure, and promote the dissolution of active ingredients. Summary of the Invention

[0006] To address the problems existing in the current technology, this invention provides an extraction device for active ingredients of plant extract additives in veterinary feed processing. The device uses a vibration generator to pre-disperse the plants in a vibrating filter cartridge. Then, based on the pressure conditions in different areas, a pressure driver drives a fan-shaped plate to further disperse the plants. After the plants are evenly dispersed, they are continuously squeezed with a complete extrusion surface to ensure uniform pressure, maximize the release of active ingredients, and improve extraction efficiency.

[0007] To address the problems of existing technologies, the present invention provides an extraction device for active ingredients of plant extract additives in veterinary feed processing, including an extraction tank and a filter cartridge disposed in the extraction tank for storing plants. The extraction tank is provided with a squeezing mechanism for applying pressure to the plants to separate the extract. The squeezing mechanism includes a pressure plate that can move along the axial direction of the filter cartridge and a pressure regulating component disposed at the bottom of the pressure plate. When the pressure plate is in operation, the pressure regulating component is activated to make the plants in the filter cartridge evenly distributed.

[0008] Preferably, the pressure regulating assembly includes a plurality of fan-shaped plates evenly distributed along the circumference of the filter cartridge. Each fan-shaped plate is capable of swinging radially relative to the pressure plate. Each fan-shaped plate has a chamfered edge that can contact the inner wall of the filter cartridge in a horizontal state. When the fan-shaped plate swings down, the pushed plant gradually moves towards the center of the filter cartridge.

[0009] Preferably, the pressure regulating assembly further includes a pressure actuator that is set and individually controlled for each sector plate. The sector plate is rotatably connected to the pressure plate near its inner side. The pressure plate is provided with a reset structure for keeping the sector plate in a horizontal state when the pressure actuator is not in operation.

[0010] Preferably, each sector plate has a pressure sensing layer at its bottom, and each pressure sensing layer is electrically connected to a corresponding pressure actuator. When the pressure value detected by the pressure sensing layer of a sector plate is significantly higher than the pressure values ​​of the other sector plates, the pressure actuator of the corresponding sector plate is in an immediate response state.

[0011] Preferably, the reset structure has an elastic connector between each sector plate and the pressure plate, wherein the elastic connector is in a stretched state when the pressure actuator drives the sector plate to swing down.

[0012] Preferably, the reset structure also has a limiting frame that cooperates with each sector plate. The limiting frame and all sector plates together form a complete extrusion surface. The limiting frame has a boss that can support the inner side of each sector plate. When the sector plate contacts the boss under the action of the elastic connector, the sector plate is in a horizontal state.

[0013] Preferably, the pressure actuator has an air bladder positioned above and near the outer side of the sector plate, and the pressure plate is provided with an inflation tube connected to the air bladder.

[0014] Preferably, the pressure plate is provided with a baffle to prevent the airbag from expanding inward toward the inside of the fan-shaped plate so that the fan-shaped plate can be normally pressed and swung downward.

[0015] Preferably, a piston is fitted onto the pressure plate to cooperate with the filter cartridge and maintain stable movement of the pressure plate.

[0016] Preferably, the filter cartridge is movable along its axial direction within the extraction tank, and a vibration generator is provided between the filter cartridge and the extraction tank.

[0017] The advantages of this application compared to the prior art are:

[0018] 1. This invention uses multiple fan-shaped plates in a pressure regulating assembly to move plants in different areas, ensuring even distribution of plants within the filter cartridge. As the pressure plate continues to press down, the pressure sensing layer continuously senses the pressure value borne by each fan-shaped plate. By adjusting the independent pressure points in different areas, it compensates for uneven pressure distribution, ensuring uniform pressure distribution.

[0019] When the system detects that the plant material in a certain area of ​​the filter cartridge is too densely packed, the corresponding fan-shaped plate will immediately respond, swinging and pushing the plant material towards the center of the filter cartridge. This gradually leads to a more uniform distribution of the plant material throughout the cartridge, preventing uneven local pressure. This makes the entire extrusion process more uniform and efficient, maximizing the release of active ingredients from the plant material and improving extraction efficiency.

[0020] 2. The present invention, through the complete extrusion surface formed by the limiting frame and each sector plate, comprehensively and stably extrudes the plant, maximizing the extraction of active ingredients from the plant.

[0021] With the support of the boss on the inner side of the sector plates combined with the force of the elastic connector, all sector plates maintain a consistent horizontal posture during the pressing process of the pressure plate. This avoids uneven local pressure caused by angular deviations of individual sector plates, ensuring high extrusion efficiency.

[0022] 3. This invention utilizes the alternating action of a first electromagnet and a second electromagnet to achieve a continuous up-and-down vibration effect in the filter cartridge. This helps to pre-disperse the plants in the filter cartridge before compression, ensuring uniform distribution of the plants within the cartridge and improving the efficiency and quality of subsequent compression and extraction.

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] See Figures 1-8 As shown, the extraction equipment for the active ingredients of plant extract additives in veterinary feed processing includes an extraction tank 1 and a filter cartridge 2 for storing plants in the extraction tank 1. The extraction tank 1 is equipped with a squeezing mechanism for applying pressure to the plants to separate the extract. The squeezing mechanism includes a pressure plate 3 that can move along the axial direction of the filter cartridge 2 and a pressure regulating component 4 located at the bottom of the pressure plate 3. When the pressure plate 3 is in operation, the pressure regulating component 4 is activated to make the plants in the filter cartridge 2 evenly distributed.

[0036] The extraction tank 1 has a feeding port 111 and a drain port 121.

[0037] The extraction tank 1 is equipped with a linear actuator 5 for driving the pressure plate 3 to move along the axis of the filter cylinder 2.

[0038] The linear actuator 5 has a screw 51 and a threaded sleeve 52 threadedly connected to the screw 51 and fixedly connected to the pressure plate 3. The extraction tank 1 is provided with a rotary actuator for driving the screw 51 to rotate, which is not shown in the figure. The extraction tank 1 is also provided with a guide rod 53 along the axial direction of the filter cartridge 2 to ensure that the pressure plate 3 moves linearly. The pressure plate 3 has a guide opening that passes through the guide rod 53.

[0039] The bottom of the filter cylinder 2 is provided with a base support 21 for supporting plants. The pressure plate 3 and the base support 21 form a pressure chamber in the filter cylinder 2. When the pressure plate 3 rises to the top of the extraction tank 1, it is convenient to put the plants into the filter cylinder 2 from the feeding port 111.

[0040] The upper end and lower end of the filter cartridge 2 are respectively provided with an upper sealing ring 22 and a lower sealing ring 23 between them and the extraction tank 1. The upper sealing ring 22, the lower sealing ring 23 and the filter cartridge 2 form an extraction chamber in the extraction tank 1. The drain port 121 is connected to the extraction chamber.

[0041] The extraction tank 1 consists of a detachable upper shell 11 and a lower shell 12. The feeding port 111 is located on the upper shell 11, and the drain port 121 is located on the lower shell 12. When it is necessary to remove the squeezed plants, the upper shell 11 is opened and the squeezing mechanism is removed together, which facilitates the cleaning of the plants in the filter cartridge 2. The filter holes of the filter cartridge 2 are periodically rinsed by a reverse flow of water from the outside to the inside.

[0042] Before the plants are fed into filter cartridge 2, the plants are properly crushed and then the active ingredients of the additives in the plant residue are further extracted by the extrusion mechanism.

[0043] As the pressing operation proceeds, the rotary driver is activated to rotate the screw 51, causing the connected threaded sleeve 52 to move downwards along the axial direction, thereby pushing the pressure plate 3 closer to the plant material inside the filter cylinder 2. At the same time, the pressure regulating component 4 installed at the bottom of the pressure plate 3 also begins to function, ensuring that the applied pressure is evenly distributed and preventing the plants from being unable to be fully pressed due to uneven distribution of the plants in the filter cylinder 2.

[0044] As the pressure plate 3 begins to move downwards, the pressure regulating component 4 monitors the resistance in multiple areas within the filter cartridge 2 in real time. If it detects that the plant accumulation in a certain area is too dense or too loose, resulting in uneven pressure, the pressure regulating component 4 will compensate for the uneven pressure difference by adjusting the independent pressure points in different areas. Specifically, for areas with denser accumulation, the plant will be dispersed towards the center of the filter cartridge 2, allowing the plant to gradually become more evenly distributed during the pressure process.

[0045] As the pressure plate 3 gradually penetrates deeper, the pressure inside the filter cartridge 2 gradually increases, causing the plant cells to rupture and release a liquid rich in active ingredients.

[0046] During this process, thanks to the guide rod 53, the pressure plate 3 maintains a straight line movement even under strong pressure, preventing unnecessary wear caused by deviating from the center. Simultaneously, the presence of the upper sealing ring 22 and the lower sealing ring 23 ensures that the extract can not flow out except through the drain port 121, guaranteeing extraction efficiency while protecting the extract from contamination.

[0047] As the pressing process continues, the extract containing active ingredients flows from the inside out through the filter cartridge 2 into the extraction chamber, and finally is discharged through the drain port 121 into an external container for further processing.

[0048] See Figures 2-8 As shown, the pressure regulating component 4 includes a plurality of fan-shaped plates 41 evenly distributed along the circumference of the filter cylinder 2. Each fan-shaped plate 41 can swing relative to the pressure plate 3 along its radial direction. Each fan-shaped plate 41 has a chamfered edge that can contact the inner wall of the filter cylinder 2 in a horizontal state. When the fan-shaped plate 41 swings down, the pushed plant gradually moves closer to the center of the filter cylinder 2.

[0049] As the pressure plate 3 begins to move downwards, multiple sector plates 41 in the pressure regulating assembly 4 installed at its bottom are activated. As the pressure plate 3 gradually moves deeper, the chamfered edges of the sector plates 41 contact and slide against the inner wall of the filter cylinder 2, thus both squeezing the plants and scraping the filter cylinder 2.

[0050] When the plants accumulate too high in a certain area of ​​the filter cartridge 2, the corresponding fan-shaped plate 41 swings, pushing the plants closer to the center of the filter cartridge 2. As the pressure plate 3 continues to press down, it not only ensures the uniform distribution of plants throughout the entire filter cartridge 2 but also effectively avoids uneven pressure caused by localized accumulation. This improves the squeezing effect and extraction efficiency, maximizing the release of active ingredients from the plants.

[0051] See Figure 2 , Figure 3 and Figures 5-10 As shown, the pressure regulating assembly 4 also includes a pressure actuator 42 that is set and individually controlled for each sector plate 41. The sector plate 41 is rotatably connected to the pressure plate 3 near its inner side. The pressure plate 3 is provided with a reset structure 31 for keeping the sector plate 41 in a horizontal state when the pressure actuator 42 is not working.

[0052] The sector plate 41 has a hinge point 411, and the pressure plate 3 has a hinge part 412 that is rotatably connected to the hinge point 411.

[0053] When the pressure actuator 42 is not in operation, the reset structure 31 on the pressure plate 3 keeps the sector plate 41 in a horizontal state to ensure the initial uniformity and stability of the plant compression, so that each sector plate 41 applies force evenly.

[0054] As the pressure plate 3 gradually penetrates deeper, the pressure actuator 42 independently adjusts the angle of each sector plate 41 according to the resistance of different areas inside the filter cartridge 2, causing the chamfered edge of the sector plate 41 to swing downward, thereby pushing the plant closer to the center of the filter cartridge 2, avoiding uneven squeezing caused by excessive or insufficient local pressure.

[0055] See Figure 3 and Figure 9 As shown, each sector plate 41 has a pressure sensing layer 43 at its bottom. Each pressure sensing layer 43 is electrically connected to the corresponding pressure actuator 42. When the pressure value detected by the pressure sensing layer 43 of a sector plate 41 is significantly higher than the pressure values ​​of the other sector plates 41, the pressure actuator 42 of the corresponding sector plate 41 is in an immediate response state.

[0056] Before the pressure plate 3 begins to press down, the reset structure 31 keeps all the sector plates 41 in a horizontal state. At this time, each pressure sensing layer 43 is in a standby state, ready to record the pressure changes that are about to occur.

[0057] As the pressure plate 3 is gradually pushed deeper, the plant is compressed, and the pressure sensing layer 43 begins to sense the pressure values ​​borne by each sector plate 41. The pressure sensing layer 43 transmits the real-time collected pressure data to the corresponding control system via electrical connection to determine whether the pressure in each area differs too much.

[0058] If the pressure value detected by the pressure sensing layer 43 of a certain sector plate 41 is significantly higher than that of other sector plates 41, the control system will identify the abnormality and immediately control the pressure actuator 42 to adjust the sector plate 41. This movement of the sector plate 41 pushes the plants in the corresponding area inwards. As the pressure plate 3 continues to press down, it ensures that the downward pressure of each sector plate 41 remains consistent without excessive differences, maximizing the release of active ingredients from the plants.

[0059] See Figures 6-9 As shown, the reset structure 31 has an elastic connector 311 connected between each sector plate 41 and the pressure plate 3. When the pressure actuator 42 drives the sector plate 41 to swing down, the elastic connector 311 is in a stretched state.

[0060] The elastic connector 311 is specifically an elastic band.

[0061] As the pressure plate 3 gradually penetrates deeper into the filter cartridge 2, the pressure actuator 42 independently adjusts the angle of each sector plate 41 according to the resistance in different areas of the filter cartridge 2, causing the chamfered edge of the sector plate 41 to swing downward. At this time, the elastic connector 311 is gradually stretched due to the downward swing of the sector plate 41, forming an energy storage state.

[0062] When the pressure actuator 42 stops working and no longer drives the fan-shaped plate 41 to swing downward, the elastic connector 311 will automatically restore the fan-shaped plate 41 to its initial horizontal position under the action of its internal elastic force. This ensures that after each plant distribution adjustment operation, the fan-shaped plate 41 can quickly reset, preparing for the next plant compression.

[0063] See Figures 5-10 As shown, the reset structure 31 also has a limiting frame 312 that cooperates with each sector plate 41. The limiting frame 312 and all sector plates 41 together form a complete extrusion surface. The limiting frame 312 has a boss 3121 that can support the inner side of each sector plate 41. When the sector plate 41 contacts the boss 3121 under the action of the elastic connector 311, the sector plate 41 is in a horizontal state.

[0064] The limiting frame 312 is a flexible structure that can adapt to the swinging of the fan-shaped plate 41.

[0065] When the pressure plate 3 begins to press down, the complete extrusion surface ensures that each sector plate 41 maintains a consistent horizontal posture throughout the pressing process, avoiding uneven pressure caused by angular deviations of individual sector plates 41. This helps to achieve efficient and consistent plant extrusion results.

[0066] As the sector plate 41 gradually returns to a horizontal state under the action of the elastic connector 311, its inner side will contact and remain in contact with the boss 3121 in the limiting frame 312. This ensures the precise alignment of the sector plate 41 in the horizontal position, allowing each sector plate 41 to maintain a consistent horizontal posture throughout the pressing process of the pressure plate 3.

[0067] See Figure 3 and Figures 6-9 As shown, the pressure actuator 42 has an airbag 421 located above and near the outer side of the sector plate 41, and the pressure plate 3 is provided with an inflation tube 422 connected to the airbag 421.

[0068] When the pressure sensing layer 43 senses an abnormal pressure on the sector plate 41, the inflation tube 422 quickly inflates the airbag 421. As the airbag 421 gradually expands, it applies downward pressure to the sector plate 41, causing the chamfered edge of the sector plate 41 to swing downward, thus achieving independent control of each sector plate 41.

[0069] By controlling each sector plate 41, the pressure in each area of ​​the filter cylinder 2 can be precisely adjusted, ensuring that the plants in different areas of the filter cylinder 2 are effectively dispersed and evenly distributed, thereby improving the efficiency and quality of the extrusion process.

[0070] See Figures 6-9 As shown, the pressure plate 3 is provided with a baffle 4211 to prevent the airbag 421 from expanding inward toward the fan-shaped plate 41 so that the fan-shaped plate 41 can be normally pressed and swung downward.

[0071] When the airbag 421 inflates, the baffle 421 prevents the airbag 421 from expanding inward toward the inside of the fan-shaped plate 41, ensuring that the pressure of the airbag 421 only acts on the outer edge of the fan-shaped plate 41. This allows the fan-shaped plate 41 to swing smoothly downward under the action of the outer pressure, pushing the plants accumulated near the inner wall of the filter cylinder 2 toward the center.

[0072] The fan-shaped plate 41 effectively disperses the plants, preventing excessive local pressure and ensuring uniform plant distribution in all areas, thereby improving the efficiency and quality of the extrusion process.

[0073] See Figures 2-4 As shown, a piston 32 is fitted on the pressure plate 3, which can cooperate with the filter cartridge 2 to maintain the stable movement of the pressure plate 3.

[0074] When the pressure plate 3 is pressed down, the piston 32 fitted on it fits tightly against the inner wall of the filter cylinder 2, ensuring that the pressure plate 3 remains stable during movement. The piston 32 slides along the inner wall of the filter cylinder 2, reducing the offset and vibration of the pressure plate 3 during movement through sealing and guiding functions.

[0075] The movement of piston 32 within filter cartridge 2 ensures not only the smooth operation of pressure plate 3 but also the uniform and stable application of pressure to all sector plates 41. Specifically, the sealing function of piston 32 prevents air leakage, while its guiding action ensures that pressure plate 3 moves in a straight line, avoiding tilting or jamming. This helps improve the precision and efficiency of the extrusion process, ensuring that the plant receives uniform pressure throughout filter cartridge 2, thereby maximizing the extraction of active ingredients.

[0076] See Figure 2 and Figure 3 As shown, the filter cartridge 2 can move along its axial direction in the extraction tank 1, and a vibration generator 6 is provided between the filter cartridge 2 and the extraction tank 1.

[0077] The vibration generator 6 is located at the bottom of the filter cylinder 2. The vibration generator 6 has a first electromagnet 61 fixed to the lower sealing ring 23 and a second electromagnet 62 fixed to the filter cylinder 2. A spring 63 is connected between the bottom of the filter cylinder 2 and the extraction tank 1.

[0078] When the first electromagnet 61 repels the second electromagnet 62, the filter cylinder 2 moves downward to compress the spring 63. Conversely, when the first electromagnet 61 attracts the second electromagnet 62, the filter cylinder 2 moves upward to release the spring 63. The coordinated movement of the first electromagnet 61 and the second electromagnet 62 drives the filter cylinder 2 to continuously move up and down, thus vibrating the filter cylinder 2 and facilitating the initial dispersion of the plants within it.

[0079] This invention uses a vibration generator 6 to vibrate the filter cartridge 2 before the plants are compressed, thus initially dispersing them. When the pressure plate 3 presses down, the pressure sensing layer 43 senses and adjusts the pressure in each area in real time, compensating for uneven pressure differences. If excessive plant accumulation is detected, the corresponding fan-shaped plate 41 swings to push the plants towards the center, avoiding uneven local pressure and improving compression efficiency.

[0080] After the plants are evenly distributed and adjusted, the entire extrusion surface, combined with the support of the boss 3121 and the elastic connector 311, keeps all the fan-shaped plates 41 in a horizontal position, ensuring an efficient and uniform extrusion effect, maximizing the release of plant active ingredients, and improving extraction efficiency and quality.

[0081] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
