Description

Technical Field

[0001] The present invention relates to the field of feed processing, and particularly to an extraction device for active ingredients of plant extracts used in veterinary feed processing. Background Art

[0002] In veterinary feed processing, traditional extraction methods mainly include placing plant raw materials in an extraction tank for steaming, dissolving active ingredients by heating, and removing residues by filtration to obtain an extract. However, relying solely on steaming, it is difficult to completely break the plant cell walls, and the active ingredients attached to the residues cannot be effectively extracted, resulting in insufficient release of active ingredients and a low extraction rate.

[0003] Currently, the Chinese authorized publication number CN118179086B discloses an extraction device and its extraction method for plant active ingredient extraction, including an extraction tank and a rolling component. By rolling the plants with the rolling component, the cell structure of the plants is damaged, promoting the dissolution of active ingredients. However, the pressure applied to the plants may be unevenly distributed at different positions, resulting in sufficient rolling of plant residues in some areas while the cell walls in other areas are not effectively damaged, affecting the release of active ingredients and thus reducing the extraction rate.

[0004] Currently, the Chinese authorized publication CN116422048B also discloses a separation device and its usage method for preparing plant powders, including a pressing plate. The top surface of the pressing plate is provided with uniformly distributed through holes for the flow of the mixed liquid, and a size adjustment component for adjusting the opening size of the through holes is arranged inside the through holes. By adaptively adjusting the inner diameter of the through holes, during the up and down movement of the pressing plate, the extrusion pressure of the pressing plate on the liquid inside the separation barrel located below or above the pressing plate can be adjusted, avoiding the problem that when the extrusion pressure of the pressing plate on the liquid is too large, the liquid enters the blocked filter holes and squeezes the solid substances. Although the pressure applied to the plants is adjusted. However, even with the through hole size adjustment mechanism, if the plant residues are unevenly distributed in the separation barrel, local pressure may still be too large or too small.

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

[0006] In view of the problems existing in the prior art, an extraction device for the active ingredients of plant extract additives for veterinary feed processing is provided. The vibrating generator vibrates the filter cylinder to pre-disperse the plants, and then, according to the pressure conditions in different regions, the sector plate is driven by the pressure driver to further disperse the plants. After the plants are evenly dispersed, they are continuously extruded with a complete extrusion surface to ensure uniform pressure, maximize the release of active ingredients, and improve the extraction efficiency.

[0007] To solve the problems of the prior art, the present invention provides an extraction device for the active ingredients of plant extract additives for veterinary feed processing, including an extraction tank and a filter cylinder arranged in the extraction tank for storing plants. An extrusion mechanism for pressing the plants to separate the extractive solution is provided on the extraction tank. The extrusion mechanism includes a pressing plate capable of moving along the axis direction of the filter cylinder and a pressure regulating component arranged at the bottom of the pressing plate. When the pressing plate is in the working state, the pressure regulating component is activated to make the plants in the filter cylinder evenly distributed.

[0008] Preferably, the pressure regulating component includes a plurality of sector plates evenly distributed along the circumferential direction of the filter cylinder. Each sector plate can swing relative to the pressing plate along its radial direction. Each sector plate has a chamfered edge that can contact the inner wall of the filter cylinder in the horizontal state. When the sector plate swings downward, the pushed plants gradually move closer to the center of the filter cylinder.

[0009] Preferably, the pressure regulating component further includes a pressure driver corresponding to each sector plate and controlled separately. The sector plate is rotatably connected to the pressing plate near its inner side position. A reset structure is provided on the pressing plate to keep the sector plate in the horizontal state when the pressure driver is not working.

[0010] Preferably, a pressure sensing layer is provided at the bottom of each sector plate. Each pressure sensing layer is electrically connected to the corresponding pressure driver. 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 driver corresponding to the sector plate is in an immediate response state.

[0011] Preferably, the reset structure has an elastic connecting piece connected between each sector plate and the pressing plate. When the pressure driver drives the sector plate to swing downward, the elastic connecting piece is in a stretched state.

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

[0013] Preferably, the pressure driver has an airbag arranged above the sector plate and near its outer side position. A pressurizing air pipe connected to the airbag is provided on the pressing plate.

[0014] Preferably, a baffle is provided on the pressing plate to block the airbag from expanding towards the inner side of the sector plate, so as to enable the sector plate to be normally pressed and swing downward.

[0015] Preferably, a piston that can cooperate with the filter cartridge is sleeved on the pressing plate to maintain the stable movement of the pressing plate.

[0016] Preferably, the filter cartridge can move along its axis direction in the extraction tank, and a vibration generator is provided between the filter cartridge and the extraction tank.

[0017] The beneficial effects of this application compared with the prior art are as follows:

[0018] 1. In the present invention, a plurality of sector plates in the pressure regulating assembly are used to stir plants in different regions, so that the plants are evenly distributed in the filter cartridge. As the pressing plate continues to press down, the pressure sensing layer senses the pressure values borne by each sector plate in real time. Adjust the independent pressure points in different regions to compensate for the uneven pressure difference and ensure that the applied pressure is evenly distributed.

[0019] When it is detected that the plants in a certain area of the filter cartridge are stacked too high and tightly, the corresponding sector plate will immediately respond, swing and push the plants to disperse towards the center of the filter cartridge, so that the plants gradually tend to be evenly distributed in the whole filter cartridge, avoiding local pressure unevenness. This makes the whole extrusion process more uniform and efficient, maximally releasing the active ingredients in the plants and improving the extraction efficiency.

[0020] 2. In the present invention, the complete extrusion surface formed by the limiting frame and each sector plate comprehensively and stably extrudes the plants, and can maximally extrude the active ingredients from the plants.

[0021] With the support of the convex platform on the inner side of the sector plate combined with the acting force of the elastic connecting piece, all the sector plates always maintain a consistent horizontal posture during the downward pressing of the pressing plate. This avoids local pressure unevenness caused by the angle deviation of individual sector plates. Ensures efficient extrusion efficiency.

[0022] 3. In the present invention, through the alternating action of the first electromagnet and the second electromagnet, the filter cartridge can continuously move up and down to achieve a vibration effect. This helps to preliminarily disperse the plants in the filter cartridge before extruding the plants, ensures the uniform distribution of the plants in the filter cartridge, and improves the efficiency and quality of subsequent extrusion and extraction.

Detailed implementation manners

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

[0035] See Figures 1-8 As shown, the extraction device for the active ingredient of the plant extract additive in veterinary feed processing includes an extraction tank 1 and a filter cylinder 2 provided in the extraction tank 1 for storing plants. An extrusion mechanism for pressing the plants to separate the extract is provided on the extraction tank 1. The extrusion mechanism includes a pressing plate 3 capable of moving along the axis direction of the filter cylinder 2 and a pressure adjustment component 4 provided at the bottom of the pressing plate 3. When the pressing plate 3 is in the working state, the pressure adjustment component 4 is activated to make the plants in the filter cylinder 2 evenly distributed.

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

[0037] A linear drive 5 for driving the pressing plate 3 to move along the axis direction of the filter cylinder 2 is provided on the extraction tank 1.

[0038] The linear drive 5 has a screw rod 51 and a threaded sleeve 52 threadedly connected to the screw rod 51 and fixedly connected to the pressing plate 3. A rotary drive for driving the screw rod 51 to rotate is provided on the extraction tank 1, and the rotary drive is not shown in the figure. A guide rod 53 for ensuring the linear movement of the pressing plate 3 is further provided on the extraction tank 1 along the axis direction of the filter cylinder 2. The pressing plate 3 has a guide opening passing through the guide rod 53.

[0039] A bottom support 21 for supporting the plants is provided at the bottom of the filter cylinder 2. A pressurization chamber is formed in the filter cylinder 2 between the pressing plate 3 and the bottom support 21. When the pressing 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] Upper sealing rings 22 and lower sealing rings 23 are respectively provided between the upper and lower ends of the filter cylinder 2 and the extraction tank 1. An extraction chamber is formed in the extraction tank 1 between the upper sealing rings 22, the lower sealing rings 23, and the filter cylinder 2. The liquid discharge port 121 is communicated with the extraction chamber.

[0041] The extraction tank 1 is composed of a detachable upper shell 11 and a lower shell 12. The feeding port 111 is provided on the upper shell 11, and the liquid discharge port 121 is provided on the lower shell 12. When it is necessary to take out the plants after extrusion, the upper shell 11 is opened and the extrusion mechanism is taken out together, which is convenient for cleaning the plants in the filter cylinder 2. The filter holes of the filter cylinder 2 are regularly backwashed by the water flow from outside to inside.

[0042] Before the plants are put into the filter cylinder 2, the plants are appropriately pulverized, and then the additive active ingredients in the plant residues are further pressed and extracted by the extrusion mechanism.

[0043] As the extrusion operation proceeds, the rotation driver is activated to rotate the screw 51, driving the connected threaded sleeve 52 to move downward along the axis, and then pushing the pressing plate 3 closer to the plant material in the filter cartridge 2. At the same time, the pressure regulating assembly 4 installed at the bottom of the pressing plate 3 also starts to function, ensuring that the applied pressure is evenly distributed and preventing incomplete extrusion of the plants due to uneven distribution in the filter cartridge 2.

[0044] When the pressing plate 3 starts to move downward, the pressure regulating assembly 4 monitors the resistance conditions in multiple areas inside the filter cartridge 2 in real time. If it detects that the plants are densely or loosely piled up in a certain area, resulting in uneven pressure, the pressure regulating assembly 4 compensates for the uneven pressure difference by adjusting the independent pressure points in different areas. Specifically, for the areas with a tighter pile, the plants at that place are dispersed towards the center of the filter cartridge 2, enabling the plants to gradually tend to be evenly distributed during the force application process.

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

[0046] During this process, due to the setting of the guide rod 53, even under the action of a strong pressure, it can ensure that the pressing plate 3 always moves in a straight line, preventing unnecessary wear caused by deviation from the center. At the same time, the presence of the upper sealing ring 22 and the lower sealing ring 23 makes it so that there is no other way for the extract to flow out except through the liquid discharge port 121, ensuring the extraction efficiency while also protecting the extract from contamination.

[0047] As the pressing process continues, the extract containing the active ingredients will flow from the inside to the outside through the filter cartridge 2 into the extraction chamber, and finally be discharged through the liquid discharge port 121 to an external container for further processing.

[0048] See Figures 2-8 As shown, the pressure regulating assembly 4 includes a plurality of sector plates 41 evenly distributed along the circumferential direction of the filter cartridge 2. Each sector plate 41 can swing radially relative to the pressing plate 3, and each sector plate 41 has a chamfered edge that can contact the inner wall of the filter cartridge 2 in the horizontal state. When the sector plate 41 swings downward, the plants being pushed gradually move closer to the center of the filter cartridge 2.

[0049] When the pressing plate 3 starts to move downward, the multiple sector plates 41 in the pressure regulating assembly 4 installed at its bottom are activated accordingly. As the pressing plate 3 gradually penetrates deeper, the chamfered edges of the sector plates 41 contact and slide along the inner wall of the filter cartridge 2, not only squeezing the plants but also scraping the inner wall of the filter cartridge 2.

[0050] When the plant accumulation in a certain area of the filter cartridge 2 is too high, the sector plate 41 corresponding to this area swings accordingly, pushing the plants towards the center of the filter cartridge 2. With the continuous downward pressure of the pressing plate 3, not only is the uniform distribution of the plants in the entire filter cartridge 2 ensured, but also the uneven pressure caused by local accumulation is effectively avoided. Thereby, the extrusion effect and extraction efficiency are improved, and the active ingredients in the plants are released maximally.

[0051] See Figure 2 、 Figure 3 and Figures 5-10 As shown, the pressure regulating assembly 4 further includes a pressure driver 42 provided corresponding to each sector plate 41 and controlled separately. The sector plate 41 is rotatably connected to the pressing plate 3 near its inner side position, and the pressing plate 3 is provided with a reset structure 31 for keeping the sector plate 41 in a horizontal state when the pressure driver 42 is in a non-operating state.

[0052] The sector plate 41 has a hinge point 411, and the pressing plate 3 has a hinge portion 412 rotatably connected to the hinge point 411.

[0053] When the pressure driver 42 is in a non-operating state, the reset structure 31 on the pressing plate 3 keeps the sector plate 41 in a horizontal state to ensure the initial uniformity and stability of the extrusion of the plants, so that each sector plate 41 applies force evenly.

[0054] As the pressing plate 3 gradually penetrates deeper, the pressure driver 42 independently adjusts the angle of each sector plate 41 according to the resistance conditions in different areas of the filter cartridge 2, so that the chamfered edge of the sector plate 41 swings downward, thereby pushing the plants towards the center of the filter cartridge 2 and avoiding uneven extrusion caused by excessive or too small local pressure.

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

[0056] Before the pressing plate 3 starts 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 upcoming pressure changes.

[0057] As the pressing plate 3 gradually penetrates deeper, the plants are squeezed, 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 through electrical connection for judging whether the pressures in each area differ 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 this abnormal situation and immediately control the pressure driver 42 to adjust the sector plate 41. Thus, the plants in the corresponding area are pushed inward by the movement of the sector plate 41. As the pressing plate 3 continues to press down, it is ensured that the downward pressure of each sector plate 41 is consistent without excessive differences, maximizing the release of active ingredients in the plants.

[0059] See Figures 6-9 As shown, the reset structure 31 has elastic connecting members 311 connected between each sector plate 41 and the pressing plate 3. When the pressure driver 42 drives the sector plate 41 to swing downward, the elastic connecting members 311 are in a stretched state.

[0060] The elastic connecting member 311 is specifically an elastic band.

[0061] As the pressing plate 3 gradually penetrates into the filter cartridge 2, the pressure driver 42 independently adjusts the angle of each sector plate 41 according to the resistance conditions 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 connecting member 311 is gradually stretched due to the downward swing of the sector plate 41, forming an energy storage state.

[0062] When the pressure driver 42 stops working and no longer drives the sector plate 41 to swing downward, the elastic connecting member 311 will automatically restore the sector plate 41 to its initial horizontal position under the action of its internal elastic force. It is ensured that after each operation of adjusting the plant distribution ends, the sector plate 41 can quickly reset to prepare for the next extrusion of the plants.

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

[0064] The limit frame 312 is a flexible structure that can adapt to the swing of the sector plate 41.

[0065] When the pressing plate 3 starts to press down, the complete extrusion surface enables each sector plate 41 to always maintain a consistent horizontal posture during the downward pressing process of the pressing plate 3, avoiding uneven pressure caused by the angle deviation of individual sector plates 41. This helps to achieve an efficient and consistent plant extrusion effect.

[0066] When the sector plate 41 gradually returns to the horizontal state under the action of the elastic connecting member 311, its inner side will contact and fit with the boss 3121 in the limit frame 312. This ensures the precise alignment of the sector plate 41 in the horizontal position, enabling each sector plate 41 to maintain a consistent horizontal attitude during the downward pressing process of the pressing plate 3.

[0067] See Figure 3 and Figures 6-9 As shown, the pressure driver 42 has an airbag 421 disposed above and near the outer side of the sector plate 41, and a pressurized air pipe 422 connected to the airbag 421 is provided on the pressing plate 3.

[0068] When the pressure sensing layer 43 senses that the pressure on the sector plate 41 is abnormal, the pressurized air pipe 422 quickly inflates the airbag 421. As the airbag 421 gradually expands, it exerts a downward pressure on the sector plate 41, causing the chamfered edge of the sector plate 41 to swing downward, achieving independent control of each sector plate 41.

[0069] By controlling each sector plate 41, the pressure in each area of the filter cartridge 2 can be precisely adjusted, ensuring the effective dispersion and uniform distribution of plants in different areas of the filter cartridge 2, thereby improving the efficiency and quality of the extrusion process.

[0070] See Figures 6-9 As shown, a baffle 4211 is provided on the pressing plate 3 to prevent the airbag 421 from expanding towards the inner side of the sector plate 41, so as to ensure that the sector plate 41 can be normally pressed and swing downward.

[0071] When the airbag 421 expands, the baffle 4211 blocks the airbag 421 from expanding towards the inner side of the sector plate 41, ensuring that the pressure of the airbag 421 only acts on the outer edge of the sector plate 41. This enables the sector plate 41 to swing downward smoothly under the action of the outer pressure, pushing the plants accumulated on the side close to the inner wall of the filter cartridge 2 towards the center for dispersion.

[0072] The effective dispersion of plants by the sector plate 41 effectively avoids the occurrence of excessive local pressure, ensures the uniform distribution of plants in each area, and thus improves the efficiency and quality of the extrusion process.

[0073] See Figures 2-4 As shown, a piston 32 that can cooperate with the filter cartridge 2 to keep the pressing plate 3 moving stably is sleeved on the pressing plate 3.

[0074] When the pressing plate 3 performs a downward pressing operation, the piston 32 sleeved on it fits tightly with the inner wall of the filter cartridge 2, ensuring that the pressing plate 3 always remains stable during the movement. The piston 32 slides along the inner wall of the filter cartridge 2, reducing the offset and vibration of the pressing plate 3 during movement through sealing and guiding functions.

[0075] The movement of the piston 32 within the filter cartridge 2 not only ensures the smooth operation of the pressing plate 3 but also guarantees that all the sector plates 41 can apply pressure evenly and smoothly. Specifically, the sealing function of the piston 32 prevents air leakage, while its guiding function ensures that the pressing plate 3 moves in a straight line, avoiding tilting or jamming. This helps to improve the accuracy and efficiency of the extrusion process, ensuring that the plants are subjected to uniform pressure throughout the 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 axially within 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 arranged at the bottom of the filter cartridge 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 cartridge 2. A spring 63 is connected between the bottom of the filter cartridge 2 and the extraction tank 1.

[0078] When the first electromagnet 61 repels the second electromagnet 62, the filter cartridge 2 moves downward to compress the spring 63, and when the first electromagnet 61 attracts the second electromagnet 62, the filter cartridge 2 moves upward to release the spring 63. Through the cooperation of the first electromagnet 61 and the second electromagnet 62, the filter cartridge 2 is driven to move up and down continuously, realizing the vibration of the filter cartridge 2, which is beneficial to the preliminary dispersion treatment of the plants in the filter cartridge 2.

[0079] In the present invention, the vibration generator 6 vibrates the filter cartridge 2 before squeezing the plants to preliminarily disperse the plants. When the pressing plate 3 presses down, the pressure sensing layer 43 senses and adjusts the pressure in each area in real time to compensate for the uneven pressure difference. When it is detected that the plant accumulation is too high, the corresponding sector plate 41 swings to push the plants to disperse towards the center, avoiding uneven local pressure and improving the extrusion efficiency.

[0080] After the uniform distribution of the plants is adjusted, through the complete extrusion surface, combined with the support of the boss 3121 and the elastic connecting member 311, all the sector plates 41 are kept in a horizontal posture, ensuring an efficient and uniform extrusion effect, maximizing the release of plant active ingredients, and improving the extraction efficiency and quality.

[0081] The above embodiments only represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
