Description

Technical Field

[0001] This invention relates to the field of antibiotic production technology, specifically to a production equipment for antibiotic alternatives in livestock and poultry. Background Technology

[0002] With the large-scale development of livestock farming and the full implementation of the "antibiotic ban", alternative antibiotic preparations for livestock and poultry, such as preparations based on active ingredients such as flavonoids and terpenes from traditional Chinese medicine, have become core products for ensuring the health of livestock and poultry. Supercritical CO2 extraction technology, due to its advantages such as low temperature, environmental protection and complete preservation of effective ingredients, has been gradually applied to the extraction process of active ingredients in alternative antibiotic preparations. However, existing supercritical CO2 extraction equipment for the production of antibiotic alternatives in livestock and poultry still faces many technical bottlenecks in practical applications, which seriously restrict the improvement of product quality and production efficiency. The specific technical problems are as follows: In existing technologies, the supercritical CO2 extraction production of antibiotic alternatives for livestock and poultry generally employs a separation mode of single extraction and centrifugal extraction. In the traditional mode, after extraction, the CO2 extract containing the active ingredients needs to be exported to separate centrifugation and pressure filtration equipment for impurity separation. During the process, not only does temperature and pressure fluctuation cause instability in the supercritical CO2 fluid, leading to oxidation and degradation of heat-sensitive active ingredients such as flavonoids and terpenes, but secondary impurities such as dust and microorganisms are also introduced during transport due to contact with the external environment, making it difficult to improve product purity. Furthermore, even with a few integrated devices... The extraction and purification units are integrated into the same framework, which can only realize a one-way process of direct purification after extraction. The extracted material is discharged after one purification. The material remaining in the purification unit cannot be returned to the extraction system for secondary dissolution. A single extraction can only extract 50%-60% of the effective components in the raw material, resulting in extremely low raw material utilization. At the same time, in the one-way process, the supercritical CO2 fluid and the material can only make contact once. The mass transfer boundary layer between the fluid and the surface of the material particles cannot be effectively broken, and some of the effective components encapsulated inside the material are difficult to dissolve, further reducing the extraction efficiency. Based on this, the present invention provides a production equipment for antibiotic alternatives in livestock and poultry to solve the problems mentioned in the background art. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a production equipment for livestock and poultry antibiotic alternatives. This solves the problem that the extraction and purification processes in existing devices are disconnected, making it impossible to achieve synergistic linkage between extraction, purification, and re-extraction, resulting in low extraction rate of effective components and insufficient product purity.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A livestock and poultry antibiotic alternative production equipment includes a frame on which a first motor and a rotary drum that rotates intermittently by 180° are provided.

A cam mechanism is provided on the output shaft of the first motor. A vibrating frame with cyclic variable stroke is connected to the cam mechanism. A main shaft and a centrifugal screen cylinder linked with the second extraction tank are rotatably connected to the vibrating frame. A pulverizing shaft is rotatably connected inside the centrifugal screen cylinder. A spraying shaft is rotatably connected to the pulverizing shaft. Both the pulverizing shaft and the spraying shaft are driven by the main shaft. Pulverizing blades are arrayed on the pulverizing shaft at positions corresponding to the inner side of the centrifugal screen cylinder. A filter screen cylinder is rotatably connected inside the first extraction tank. The filter screen cylinder and the centrifugal screen cylinder rotate synchronously and slide in contact.

[0009] As a preferred technical solution of the present invention, the reversing transmission system further includes a fixed gear ring installed on the second extraction tank, and a rotating gear meshing with the fixed gear ring is installed on the main shaft. The rotating gear is meshed with the fixed gear ring, and the tooth height of the fixed gear ring is 5 to 8 times the tooth height of the rotating gear. Three third transmission belts are connected to the main shaft, and the three third transmission belts are respectively connected to the centrifugal screen, the crushing shaft and the spraying shaft. When the main shaft rotates, the speed ratio of the centrifugal screen, the crushing shaft and the spraying shaft is 3:6:1.

[0010] As a preferred technical solution of the present invention, the cam mechanism includes a cam disk fixed on a sleeve, four cam protrusions arranged in an array along the circumferential direction, a driven roller rotatably connected to the vibrating frame, the four cam protrusions alternately abutting and driving the driven roller, and the driving stroke of the four cam protrusions on the driven roller increases in the counterclockwise direction, a guide frame is fixedly installed on the rotary drum, a positioning guide groove is opened on the vibrating frame, the guide frame is slidably connected to the positioning guide groove, a washer is rotatably connected to the tail of the second extraction tank, and a spring is installed between the washer and the vibrating frame.

[0014] The beneficial effects of this invention are: 1. Addressing the issues of disconnected extraction and purification processes and the inability to circulate in unidirectional integration in existing technologies, this invention constructs an integrated circulating operation system through 180° intermittent rotation of the rotary drum, a reversible transmission system, and a dual-tank linkage structure. The rotation of the rotary drum allows the material to circulate between the first and second extraction tanks. The reversible transmission system precisely controls the forward and reverse rotation of the main shaft. When the main shaft is at the bottom, the spiral pressure plate performs pressure filtration extraction; when it is at the top, it pushes the residual material back to the centrifuge mesh, realizing a closed-loop process of extraction, purification, and secondary extraction. Compared to existing offline modes that require material transfer leading to supercritical CO2 instability and oxidation degradation of heat-sensitive components, and the problem that unidirectional integrated equipment can only perform single extractions, this equipment eliminates the need for material transfer, maintains stable temperature and pressure throughout the process, avoids secondary contamination, and improves the extraction rate of effective components from the raw materials.

[0015] 2. Addressing the issue of single-pass contact between CO2 fluid and material in existing equipment, and the inability to break the mass transfer boundary layer, this invention integrates three core units: variable stroke vibration of the cam mechanism, multi-stage speed-linked crushing, and directional CO2 injection, forming a dynamic mass transfer enhancement system. The cam mechanism drives the vibrating frame to circulate through four cam protrusions with increasing strokes, breaking up material agglomerates and dynamically disturbing the material layer. The crushing shaft, centrifugal screen, and injection shaft operate in a coordinated speed ratio of 3:6:1. The crushing shaft refines the material to the target particle size to increase the specific surface area, while the injection shaft uniformly injects supercritical CO2 through injection holes, achieving full countercurrent contact between the fluid and material. The stirring plates on the inner wall of the first extraction tank simultaneously stir, further breaking the solid-liquid interface mass transfer boundary layer. Compared to the existing technology that relies on a single extraction power source, this equipment accelerates the dissolution of effective components and shortens the extraction cycle through multi-unit linkage of vibration turbulence, surface refinement, directional injection, and stirring assistance, achieving deep synergy between mechanical action and fluid mass transfer, and significantly improving the equipment's processing efficiency.

[0018] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0019] The present invention provides the following preferred embodiments, such as Figure 1-9 As shown, a livestock and poultry antibiotic alternative production equipment includes a frame 1, on which a first motor 2 and a rotary drum 3 that rotates intermittently by 180° are mounted. The two ends of the rotary drum 3 are respectively rotatably connected to a first extraction tank 4 and a second extraction tank 5 driven to rotate by the first motor 2. In a preferred embodiment, the length of the first extraction tank 4 is 90cm and the length of the second extraction tank 5 is 75cm. A left rotating shaft 23 and a right rotating shaft 24 are fixedly connected to the rotary drum 3. A sleeve 25 is rotatably sleeved on the left rotating shaft 23. The right rotating shaft 24 and the sleeve 25 are rotatably connected to the frame 1 through bearings. A first transmission belt is driven to the output shaft of the first motor 2. The first transmission belt is driven to the left rotating shaft 23. A driving bevel gear is installed on the sleeve 25. A driven bevel gear ring is installed on the first extraction tank 4 and the second extraction tank 5. Both driven bevel gear rings are meshed with the driving bevel gear. The two driven bevel gear rings are respectively set on both sides of the driving bevel gear. By setting the first motor 2, the rotary drum 3 can be rotated 180° periodically. In a preferred embodiment, the rotation cycle is set to 8 minutes. By rotating the rotary drum 3, the extract material is circulated into the centrifugal mesh drum 8 and the filter press drum 12, thereby enabling the device to cycle through centrifugal extraction mode and filter press extraction mode. Meanwhile, the rotation of the rotary drum 3 allows the raw materials for the production of antibiotics to be evenly distributed within the equipment, avoiding dead zones in extraction caused by local accumulation. The synchronous rotation of the first extraction tank 4 and the second extraction tank 5 provides stability for the full contact between the supercritical CO2 fluid and the material, and for the initial separation of the effective components. The output shaft of the first motor 2 is equipped with a cam mechanism, and the cam mechanism is connected to a vibrating frame 6 that vibrates in a cyclic variable stroke. The cam mechanism includes a cam disk 35 fixed on the sleeve 25. Four cam protrusions 36 are arranged in an array on the cam disk 35 along the circumferential direction. A driven roller 37 is rotatably connected to the vibrating frame 6. The four cam protrusions 36 alternately abut against the driven roller 37 for transmission. In the counterclockwise direction, the driving stroke of the four cam protrusions 36 on the driven roller 37 increases. A guide frame 38 is fixedly installed on the rotary drum 3. A positioning guide groove is opened on the vibrating frame 6. The guide frame 38 is slidably connected to the positioning guide groove. A washer ring 39 is rotatably connected to the tail of the second extraction tank 5. A spring 40 is installed between the washer ring 39 and the vibrating frame 6. In a preferred embodiment, the driving strokes of the four cam protrusions 36 to the driven rollers 37 in the counterclockwise direction are 1cm, 2cm, 3cm and 4cm respectively; The cam convex 36 with four increasing strokes drives the vibrating frame 6 to achieve cyclic variable stroke vibration. With the sliding guidance of the guide frame 38 and the positioning guide groove and the elastic reset effect of the spring 40, it can break up the agglomerates of raw materials for the production of anti-agents during the raw material feeding stage, ensuring that the material enters the centrifugal screen 8 and the filter screen 12 evenly, and effectively avoid clogging of the extraction screen 15. On the other hand, during the extraction process, vibration can dynamically disturb the material layer, break the mass transfer boundary layer at the solid-liquid interface, accelerate the dissolution of effective components by supercritical CO2 fluid, enhance the equipment's adaptability to raw materials, and indirectly improve the extraction efficiency of effective components. Temperature probe 17, pressure probe 18 and pressure relief valve 19 are respectively installed on the rotary drum 3. Central control unit 20 is installed on the frame 1. The data terminals of temperature probe 17 and pressure probe 18 are connected to the central control unit 20. A material valve 21 is fixedly installed at the tail end of the first extraction tank 4. The tail end of the material valve 21 is connected to the inner cavity of the filter screen cylinder 12. Electric heating jacket 22 is integrated in both the first extraction tank 4 and the second extraction tank 5. Temperature control sensor is integrated in the electric heating jacket 22. The data terminal of the temperature control sensor is connected to the central control unit 20. During feeding, the first extraction tank 4 is located directly above the second extraction tank 5. The feed valve 21 is opened, and the extraction aid and poultry antibiotic alternative raw materials are fed in through the feed valve 21. When the first extraction tank 4 is located directly above the second extraction tank 5, the conveying direction of the spiral pressure plate 14 is downward, which further feeds the poultry antibiotic alternative raw materials into the interior of this production equipment. At the same time, when the extraction aid is fed in, it should be ensured that the amount of extraction aid fed in does not exceed two-thirds of the volume of the second extraction tank 5. By integrating data feedback from temperature probe 17, pressure probe 18 and temperature control sensor through the central control unit 20, the equipment can achieve real-time and precise control of extraction temperature of 55℃ and extraction pressure of 50MPa, perfectly matching the strict requirements of process parameters in the CO2 pressurized extraction stage, ensuring the stable formation of supercritical CO2 fluid, and maximizing the retention of heat-sensitive effective components such as flavonoids and terpenes. The electric heating jacket 22 provides a uniform heating environment, avoiding local temperature deviations from affecting the extraction effect; Pressure relief valve 19 can release overpressure gas in a timely manner to ensure the safe operation of the equipment; The vibrating frame 6 is rotatably connected to the main shaft 7 and the centrifugal screen 8, which are linked to the second extraction tank 5. The centrifugal screen 8 is rotatably connected to the crushing shaft 9, and the crushing shaft 9 is rotatably connected to the jetting shaft 10. Both the crushing shaft 9 and the jetting shaft 10 are driven by the main shaft 7. Crushing blades 11 are installed on the crushing shaft 9 and at positions corresponding to the inside of the centrifugal screen 8. A filter cylinder 12 is rotatably connected inside the first extraction tank 4. The filter cylinder 12 rotates synchronously with the centrifugal filter cylinder 8 and is also slidably attached to it. Specifically, the filter press cylinder 12 has two symmetrically arranged transmission guide grooves 41, and the centrifugal filter cylinder 8 has two transmission guide bars installed on the top. The two transmission guide bars are slidably connected to the two transmission guide grooves 41 respectively. Both the filter press cylinder 12 and the centrifugal filter cylinder 8 are made of 304 stainless steel. The inner wall of the first extraction tank 4 is provided with an array of stirring plates 13, and a spiral pressure plate 14 is installed on the injection shaft 10 at a position corresponding to the inner side of the filter cylinder 12. Both the filter cylinder 12 and the centrifugal cylinder 8 are provided with arrays of extraction mesh holes 15, and the injection shaft 10 is provided with arrays of injection holes 16. Through the sliding connection between the transmission guide bar and the transmission guide groove 41, the synchronous rotation and flexible relative sliding of the filter screen cylinder 12 and the centrifugal screen cylinder 8 are realized. The 304 stainless steel material has both corrosion resistance and high strength characteristics, and is suitable for the working environment of CO2 pressure extraction. During the centrifugation and pressure filtration purification stages, the centrifugal mesh 8 rotates to generate a centrifugal force of 4000 r / min, which, combined with the mechanical pressure of 1.2 MPa of the pressure filter 12, forms a synergistic extraction effect of centrifugation and pressure filtration. The extraction mesh 15 can efficiently trap impurities such as wax and macromolecular colloids, allowing the clarified extract to pass through smoothly. It also includes a reversing transmission system, which drives the main shaft 7 to rotate forward when it is directly below the rotation axis of the rotary drum 3, and to rotate in reverse when it is directly above the rotation axis of the rotary drum 3; The reversing transmission system includes a reversing gear 26 mounted on a sleeve 25, a support plate 27 mounted on a left rotating shaft 23, a central shaft 28 rotatably connected to the support plate 27, an intermediate gear 29 mounted on the central shaft 28, the intermediate gear 29 meshing with the reversing gear 26, two outer shafts 30 rotatably connected to the frame 1, each outer shaft 30 mounted with an external gear 31, the two external gears 31 alternately meshing with the reversing gear 26, a second motor 32 mounted on the frame 1, a second transmission belt drivingly connected to the output shaft of the second motor 32, both outer shafts 30 drivingly connected to the second transmission belt, the two outer shafts 30 being respectively positioned directly above and below the left rotating shaft 23, and both external gears 31 being positioned outside the reversing gear 26; Through the alternating meshing of the reversing gear 26, the intermediate gear 29 and the two external gears 31, the main shaft 7 is driven by the second motor 32 to rotate forward when it is directly below the rotation axis of the rotary drum 3 and reverse when it is directly above it, forming a precise linkage with the 180° intermittent rotation of the rotary drum 3; When the main shaft 7 rotates forward, the extrusion direction of the spiral pressure plate 14 is downward, and then the filter press operation is performed; When the main shaft 7 reverses upwards, the extrusion direction of the spiral pressure plate 14 reverses, thereby discharging the extract material remaining in the filter cylinder 12 to the centrifugal cylinder 8 and realizing reverse pushing of material, thus achieving the switching and circulation of material position; The reversing transmission system also includes a fixed gear ring 33 installed on the second extraction tank 5, a rotating gear 34 that meshes with the fixed gear ring 33 installed on the main shaft 7, the rotating gear 34 meshing with the fixed gear ring 33, and three third transmission belts that are connected to the main shaft 7 for transmission. The three third transmission belts are respectively connected to the centrifugal screen 8, the crushing shaft 9 and the spraying shaft 10. When the main shaft 7 rotates, the speed ratio of the centrifugal screen 8, the crushing shaft 9 and the spraying shaft 10 is 3:6:1. Specifically, the three third transmission belts are connected to the three transmission wheels on the main shaft 7, and the diameter ratio of the transmission wheels matches the speed ratio of the centrifugal screen 8, the crushing shaft 9 and the spraying shaft 10, which is 3:6:1. The design of a tooth height ratio of 7 times between the fixed gear ring 33 and the rotating gear 34 ensures that the two can maintain stable meshing and transmission when the vibrating frame 6 vibrates, thus avoiding transmission interruption. The main shaft 7 drives the centrifugal screen 8, the crushing shaft 9, and the spraying shaft 10 to operate at a speed ratio of 3:6:1 via the third transmission belt. The maximum speed of the crushing shaft 9 can further refine the herbal particles to the target particle size, increase the specific surface area, and improve the CO2 contact efficiency. The centrifugal screen 8 operates at a moderate speed to provide stable centrifugal force, while the jet shaft 10 operates at the slowest speed to ensure that the jet holes 16 uniformly spray supercritical CO2 fluid, allowing the fluid to fully contact the herbal particles in a countercurrent flow. The coordinated optimization of the speeds of the three components not only ensures the independent effects of each process of crushing, extraction, and centrifugation, but also enables multiple processes to be carried out simultaneously and efficiently, thereby improving the overall processing capacity of the equipment and the purity of the product. It also includes an exhaust system for supplying CO2 to the injection port 16 and for venting the extraction gas flow from the rotary drum 3.

[0020] The air supply and exhaust system includes an airflow duct 42 opened in the right-hand rotating shaft 24, which is connected to the inner cavity of the rotating cylinder 3. An extraction pipe 43 connected to the airflow duct 42 is installed on the side of the frame 1. An axial flow fan is installed in the extraction pipe 43. Fan blades 44 are arranged in an array on the outer periphery of the centrifugal mesh cylinder 8 and at positions corresponding to the inner side of the rotating cylinder 3.

[0021] The air supply and exhaust system also includes a guide ring pipe 45 fixedly installed on the frame 1. A ring distributor 46 is rotatably connected to the guide ring pipe 45. An air supply pipe 47 is connected to the ring distributor 46. A guide pipe 48 is fixedly installed on the material valve 21. The guide pipe 48 is rotatably connected to the air supply pipe 47. A flow channel is opened in the injection shaft 10. Each injection hole 16 and the air outlet end of the guide pipe 48 are connected to the flow channel. A first sealing ring that fits into the flow channel is fixedly installed on the guide pipe 48. A second sealing ring that fits into the filter screen cylinder 12 is fixedly installed on the inner wall of the centrifugal screen cylinder 8. A CO2 supply connector 49 is fixedly connected to the guide ring pipe 45.

[0022] The air supply and exhaust system is connected to a supercritical CO2 gas source through CO2 supply connector 49, and the central control unit 20 adjusts the gas supply flow rate according to the data of the pressure probe 18. The axial flow fan in the extraction pipe 43 has a power of 1.5kW, and the exhaust rate and air supply rate are dynamically matched to maintain the pressure in the rotary drum 3 at 50MPa±0.5MPa. The supply and exhaust system achieves efficient bidirectional operation of CO2 supply and extraction gas flow. The CO2 supply path passes through the gas guide ring pipe 45, the ring distributor 46, the gas guide pipe 48 and the inner flow channel of the injection shaft 10, ensuring that the supercritical CO2 fluid is uniformly injected into the material through the injection hole 16, which meets the requirement of the fluid flowing back through the material layer in the CO2 pressurized extraction stage and improves the dissolution efficiency of the effective components. Specifically, CO2 fluid is ejected from the injection hole 16 of the injection shaft 10 and flows out from the extraction mesh 15 of the filter cylinder 12 and the centrifugal cylinder 8, achieving countercurrent contact with the material; The first and second sealing rings ensure the airtightness of the CO2 transport process and reduce leakage; The airflow channel 42 and extraction pipe 43, together with the axial flow fan and fan blade 44, can quickly export the extraction airflow in the rotary drum 3, avoiding airflow accumulation that affects pressure stability. The fan blade 44 generates auxiliary airflow as the centrifugal mesh drum 8 rotates, accelerating the discharge of the extraction airflow and providing a pre-conditioning for subsequent depressurization concentration to remove residual trace CO2. The overall structure takes into account efficient CO2 supply, recycling and timely discharge of extraction by-products, balancing environmental protection and energy saving with process efficiency.

[0023] The specific steps for using this invention are as follows: During the feeding stage, the first extraction tank 4 is located directly above the second extraction tank 5. The feed valve 21 is opened, and the poultry alternative antibiotic raw material and extraction auxiliary agent not exceeding two-thirds of the volume of the second extraction tank 5 are fed in. The central control unit 20 integrates the data from the temperature probe 17, the pressure probe 18 and the temperature control sensor in the electric heating jacket 22 to accurately regulate the extraction temperature of 55℃ and the extraction pressure of 50MPa inside the equipment, ensuring the stable formation of supercritical CO2 fluid. The pressure relief valve 19 ensures pressure safety in real time. Meanwhile, the second motor 32 drives the reversing transmission system through the second transmission belt. With the alternating meshing of the reversing gear 26, the intermediate gear 29 and the external gears 31 on the two outer shafts 30, the main shaft 7 rotates forward when it is directly below the rotation axis of the rotary drum 3 and reverses when it is directly above it. The main shaft 7 drives the centrifugal screen 8, the crushing shaft 9 and the spray shaft 10 to rotate through the third transmission belt at a speed ratio of 3:6:1. The blades on the crushing shaft 9 refine the material. The spray shaft 10 sprays CO2 evenly through the spray hole 16 through the air guide ring pipe 45, the annular distributor 46 and the air guide pipe 48 of the air supply and exhaust system. The cam mechanism on the sleeve 25 drives the vibrating frame 6 to cyclically vibrate with varying stroke through four cam protrusions 36 with increasing stroke. It works in conjunction with the guide frame 38 for guidance and the spring 40 for reset, breaking up material agglomerates and accelerating mass transfer. During the rotation of the rotary drum 3, the filter screen cylinder 12 rotates synchronously and slides into contact with the transmission guide groove 41 of the centrifugal screen cylinder 8 through the transmission guide bar. When the main shaft 7 rotates forward, the spiral pressure plate 14 presses downward to perform pressure filtration extraction. When it rotates in reverse, the residual material is discharged to the centrifugal screen cylinder 8. The centrifugal force generated by the rotation of the centrifugal screen cylinder 8 works synergistically with the pressure filtration, and impurities are intercepted through the extraction mesh 15. The stirring plate 13 on the inner wall of the first extraction tank 4 assists in mixing the material. The extraction airflow is discharged through the airflow channel 42 of the right rotating shaft 24, the extraction pipe 43 and the axial flow fan. The fan blade 44 assists in accelerating the exhaust. Finally, the material is circulated for centrifugal extraction and pressure filtration extraction, which efficiently extracts the effective components of the livestock and poultry antibiotic alternative and completes the purification.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
