Description

Technical Field

[0001] This invention relates to the field of feed processing technology, and in particular to a dual-station alternating feeding equipment for compounding feed nutrient and antibacterial components. Background Technology

[0002] With the development of large-scale livestock and poultry farming and the feed industry, higher requirements have been placed on the nutritional uniformity, processing stability, and microbial control capabilities of feed products during storage. In addition to basic proteins, carbohydrates, minerals, and other nutritional raw materials, the preparation of some functional feeds or feed additives also requires the addition of liquid functional components with antibacterial, preservative, or storage stability-improving effects to the powdered nutrient matrix. This allows the liquid functional components to be distributed or loaded relatively evenly on the surface of the powdered material, thereby obtaining a compound feed that combines nutritional and antibacterial preservation functions.

[0003] Because the powdered nutrient components and the liquid antibacterial components differ significantly in physical state, flow properties, density, and rheological characteristics, the feeding method and initial contact state of the two materials have a substantial impact on the subsequent uniformity of the composite. Existing equipment typically employs a centralized feeding method, where a certain amount of powdered raw material is first added to a mixing tank or reaction vessel, followed by the addition of the liquid functional component in a single batch, and then mixed using a mechanical stirring mechanism. While this method offers a relatively simple equipment structure, when the liquid material enters the powder material in a concentrated manner within a short period, the liquid tends to preferentially wet the powder near its entry point, causing a rapid increase in the liquid content of the powder in that area. Meanwhile, the powder farther from the liquid entry point remains relatively dry, resulting in significant localized concentration differences.

[0004] Especially when the powder particles have a certain degree of liquid absorption or the liquid antibacterial component has a certain viscosity, the concentrated addition of liquid can easily cause local powder adhesion and agglomeration, forming wet clumps or lumps. Once wet clumps form, the internal material cannot continue to fully exchange with the external liquid and powder. It takes a long time to gradually disperse them using only a regular stirring paddle, which not only prolongs the mixing time but may also cause differences in the loading of antibacterial components on different areas and on the surface of different powder particles, thus affecting the uniformity and batch stability of the final compound.

[0005] To address the problems associated with centralized feeding, some equipment is equipped with two or more feed inlets, allowing different materials to enter the mixing chamber separately. However, when powder and liquid materials are simultaneously and continuously fed into the same area from different inlets, without proper feeding sequence control, the two materials may still meet directly in the feeding area. When a liquid jet or concentrated liquid flow directly impacts the powder, it can easily cause localized over-wetting, leading to instantaneous powder agglomeration and potentially causing some powder to adhere to the feed inlet, guide surface, or inner wall of the tank. Therefore, simply increasing the number of feed inlets cannot effectively solve the problem of uneven initial contact between solid and liquid materials; coordinated control of the feeding sequence and entry method of the two materials is also necessary.

[0006] Meanwhile, powder materials themselves also present feeding stability issues. In the hopper, powders are affected by their moisture content, particle shape, particle size, and hopper structure, easily leading to phenomena such as bridging, adhesion to the walls, localized compaction, or intermittent collapse, causing fluctuations in the actual amount of material entering the mixing chamber per unit time. For liquid functional components with a certain viscosity, their flow rate can also be affected by changes in liquid level and flow resistance. If the powder and liquid feeding lack a matching conveying structure, even with two independent feeding channels, the actual feeding speed of the two materials may not match the set feeding cycle, further affecting their compounding ratio and mixing stability.

[0007] Furthermore, most existing feed mixing equipment relies primarily on a single-stage agitator located inside the tank for overall material mixing. For already formed wet clumps, areas of high-concentration liquid, and droplets adhering to the powder surface, the shearing and circulating effects generated by macroscopic mixing alone are often insufficient to achieve adequate dispersion in a short time. Especially when the tank size is large or the powder-to-liquid ratio is low, dead mixing zones may form inside the tank, requiring extended mixing time to achieve the desired uniformity, thus increasing equipment operating time and energy consumption.

[0008] Therefore, before the powdered nutrients and liquid antibacterial components actually enter the main mixing zone, if the concentrated liquid can be diverted into multiple smaller liquid streams, allowing the powder and dispersed liquid to gradually come into contact during movement, the instantaneous liquid addition and local humidity in a single area can be reduced. However, ordinary fixed material guiding structures are prone to powder accumulation and material adhesion, which may lead to a decrease in feeding speed or even blockage as the operating time increases. Therefore, it is also necessary to keep the materials in the premixing zone in continuous motion, promoting powder dispersion, liquid diversion, and sufficient contact between the two, while preventing materials from remaining on the surface of the material guiding structure for extended periods.

[0009] On the other hand, simply completing the initial contact is insufficient to ensure that the liquid antibacterial components are fully and evenly distributed throughout all the powdered nutrients. If the pre-mixed material is directly introduced into the bottom of the tank for ordinary stirring, a relatively long macroscopic mixing process is still required. Therefore, it is necessary to further disperse the material after premixing, so that the initially formed solid-liquid mixture can be redistributed in different directions on a smaller scale. Combined with the overall circulation and agitation inside the tank, the consistency of the material composition in each area can be gradually improved.

[0010] In existing equipment, the feeding mechanism, feed control mechanism, and mixing mechanism are often driven by multiple independent power sources. Although separate driving allows for individual adjustment of the operating status of each mechanism, in working scenarios requiring powder feeding, liquid feeding, alternating feeding, and multi-stage mixing, additional control and synchronization systems are needed between multiple power mechanisms. This not only increases the complexity of the equipment structure and control but may also further cause feeding fluctuations and mixing instability when the action rhythms of each mechanism are mismatched. Therefore, how to achieve relatively stable mechanical linkage between different actions while ensuring the effective operation of each functional mechanism is also a problem that needs to be considered for this type of equipment.

[0011] Furthermore, powdered nutrient raw materials may absorb moisture during storage and transportation. Moisture reduces the flowability of the powder, making it more prone to clumping, adhesion to the walls, or discontinuous feeding. Existing equipment typically focuses primarily on the mixing process inside the mixing tank, neglecting the conditioning of the powder's state before it enters the mixing tank. Therefore, pre-treating the powder materials under suitable conditions without affecting the stability of the raw materials can reduce the adverse effects of moisture on the powder's flowability and subsequent mixing process, and also help improve the stability of the entire composite preparation process.

[0012] In summary, existing devices for compounding powdered nutrients and liquid antibacterial components still suffer from several problems, including: concentrated contact between powder and liquid can easily lead to excessive wetting and agglomeration; difficulty in coordinating the feeding and infeeding cycles of the two materials; powder tending to adhere to the walls or cause blockages; low efficiency of single-stage stirring in eliminating agglomerates and local concentration differences; lack of effective connection between premixing and deep mixing; and complex synchronous control among multiple functional mechanisms. Therefore, it is necessary to provide a compound reaction device capable of separately conveying and alternately feeding powder and liquid materials, and capable of sequentially completing diversion contact, dynamic premixing, secondary dispersion, and overall stirring after entering the main reaction zone. This would reduce the risk of agglomeration caused by direct concentrated contact between solid and liquid materials, improve the uniformity of contact and dispersion of the two components, and enhance the stability of the entire compound processing process. Summary of the Invention

[0013] To address the problems in existing processing methods for compounding powdered nutrients and liquid antibacterial components, such as the tendency for concentrated contact between solid and liquid materials to cause localized over-wetting and agglomeration, difficulty in coordinating the feeding rhythm of the two materials, and the challenge of achieving rapid uniform dispersion through single-stage mixing, this invention provides a dual-station alternating feeding feed nutrient antibacterial component compounding and mixing device. By separately conveying powdered nutrients and liquid antibacterial components and feeding them alternately at a predetermined rhythm, combined with diversion vibration premixing and centrifugal dispersion mixing, the two components gradually come into contact and disperse after entering the reaction tank, thereby improving the uniformity of the compounding. The device includes a reaction tank, with a top cover fixedly installed on the top. Two mounting seats are fixedly installed in the middle of the top of the top cover. A first feed hopper and a second feed hopper with dual-station feeding are fixedly installed on both sides of the two mounting seats. The bottom discharge ends of the first feed hopper and the second feed hopper are both fixedly connected to the top of the reaction tank through the top cover.

[0014] The reaction vessel and the top center of the top cover and the middle of the mounting base are provided with a first mounting hole, and the inner wall of the first mounting hole is rotatably connected to a central shaft through a sealed bearing. An alternating feeding assembly located inside the top cover is provided between the outer wall of the central shaft and the two feed pipes.

[0015] The first feed hopper is provided with a first discharge component, and the second feed hopper is provided with a second discharge component. The top of the first discharge component, the second discharge component, and the central shaft are provided with a drive mechanism.

[0016] The reaction vessel is equipped with a first mixing component and a second mixing component arranged from top to bottom, and both the first mixing component and the second mixing component are linked to the central axis.

[0017] Furthermore, the alternating feeding assembly includes a turntable fixedly mounted on a central shaft, with a cam groove on the top of the turntable. Both ends of the inner wall of the cam groove are slidably fitted with pulleys. The tops of the two pulleys are rotatably connected to push-pull rods via pins. Both feed pipes have openings at their midpoints. One end of each push-pull rod is fixed with a feed plate that moves along the opening. The feed plate has a feed groove corresponding to and communicating with the feed pipe. The cam groove is a closed, non-circular cam groove, and its radial distance from the central shaft changes periodically at different circumferential positions. The two pulleys are circumferentially offset and 180° apart, thus ensuring the two feed plates are in an alternating communication state.

[0018] Furthermore, two symmetrical annular sealing seats are fixedly installed on the inner wall of the feed pipe and attached to the upper and lower parts of the feed plate, and the annular sealing seats are connected to the feed groove. Two fixing plates are fixed on both sides of the outer wall of the feed pipe, and sealing gaskets that are attached to the upper and lower parts of the feed plate are fixedly installed on the opposite surfaces of the two fixing plates.

[0019] Furthermore, the first discharge assembly includes a second mounting hole located at the middle of the top of the first feed hopper, and the inner wall of the second mounting hole is rotatably connected to a first drive shaft via a sealed bearing. A spiral blade is fixedly installed on the outer wall of the first drive shaft. The second discharge assembly includes a third mounting hole located at the middle of the top of the second feed hopper, and the inner wall of the third mounting hole is rotatably connected to a second drive shaft via a sealed bearing. A double-sided turbine blade is fixedly installed at the bottom of the second drive shaft. The blades of the double-sided turbine blade are set at a preset tilt angle, with a tilt angle range of 15° to 35°. Their rotation direction matches the rotation direction of the second drive shaft. When the blades rotate, they form an axial push flow towards the downward feed pipe, pushing the liquid antibacterial components in the second feed hopper downward at a uniform speed.

[0020] Furthermore, the drive mechanism includes a drive frame fixedly installed on the top of the first feed hopper and the second feed hopper, and double pulleys are fixedly installed on the top ends of the first drive shaft, the second drive shaft and the central shaft extending into the drive frame. A transmission belt is connected between adjacent double pulleys. The diameter of the double pulley at the top of the central shaft is smaller than the diameter of the double pulley at the top of the first drive shaft and also smaller than the diameter of the double pulley at the top of the second drive shaft. A preset transmission ratio is formed by the difference in pulley diameters. The rotational speed of the central shaft is 2 to 4 times that of the drive shaft, so that the central shaft obtains a higher working speed than the first drive shaft and the second drive shaft. A drive motor is fixedly installed on the top of the drive frame, and the output shaft of the drive motor is fixedly connected to the top of the central shaft.

[0021] Further, the first mixing assembly includes a first hinge seat and a second hinge seat fixedly installed on both sides of the inner wall of the top of the reaction vessel. A first feeding slant frame is rotatably connected to the first hinge seat via a pin, and a second feeding slant frame is rotatably connected to the second hinge seat via a pin. The bottom end of the second feeding slant frame is located inside the first feeding slant frame, and third V-shaped elastic supports are fixedly installed on both sides of the bottom of the second feeding slant frame to the inner walls of both sides of the first feeding slant frame. Second V-shaped elastic supports are fixedly installed on both sides of the top of the first feeding slant frame to the inner wall of the top of the reaction vessel, and first V-shaped elastic supports are fixedly installed on both sides of the top of the second feeding slant frame to the inner wall of the top of the reaction vessel. The frame has a movable hole for the central shaft to pass through, and a leak-proof cylinder is fixed to the top of the movable hole. The bottom end of the second feeding inclined frame has a lower drain for the powder nutrients to fall into the first feeding inclined frame. A diversion component is provided on the inner wall of the second feeding inclined frame near the lower drain. An extrusion seat is fixedly installed at the bottom of the first feeding inclined frame, and several support rods are fixed on the outer wall of the central shaft. One end of the support rod is fixed with the same annular actuating frame. The annular actuating frame is located below the extrusion seat. The annular actuating frame is in a continuous alternating convex and concave shape. The feed pipe outlet corresponding to the first feed hopper corresponds vertically to the lower drain, and the feed pipe outlet corresponding to the second feed hopper is located above the second feeding inclined frame.

[0022] Furthermore, the diversion assembly includes an inclined seat fixedly installed on the inner wall of the second feeding inclined frame, and a number of equally spaced diversion plates are fixed on the top of the inclined seat, with the gap between two adjacent diversion plates designed as a diversion groove.

[0023] Furthermore, the second mixing assembly includes a centrifuge cylinder fixed to the outer wall of the central shaft, and several support columns are fixed to the top of the centrifuge cylinder and the bottom of the annular agitator. Several annularly distributed discharge holes are opened on the circumference and bottom of the centrifuge cylinder, and an agitator is fixedly installed at the bottom of the central shaft.

[0024] Furthermore, an inner liner is fixedly installed on the inner wall of the first feed hopper, and a heating tube is fixedly installed at the gap between the outer wall of the inner liner and the inner wall of the first feed hopper. The heating tube is electrically connected to a controller.

[0025] Furthermore, both the first and second feed hoppers are equipped with feed pipes at their tops, and the tops of the feed pipes are equipped with sealing caps. A discharge valve is fixedly installed at the bottom discharge end of the reaction vessel, and a support frame is fixedly installed on the bottom outer wall of the reaction vessel.

[0026] In some embodiments, the mass ratio of powdered nutrients to liquid antibacterial components can be 30:1 to 2000:1, preferably 100:1 to 500:1; the particle size of the powdered nutrients can be 100 to 1500 μm, preferably 300 to 1000 μm; the dynamic viscosity of the liquid antibacterial components at the operating temperature can be 1 to 300 mPa·s, preferably 2 to 100 mPa·s; the preheating temperature of the powdered nutrients can be 25 to 50°C, preferably 30 to 40°C; and the rotational speed of the central shaft 13... The speed can be 100–400 r / min, preferably 150–300 r / min; the total volume after adding a single batch of materials can account for 20%–70% of the effective volume of the reaction vessel 1, preferably 30%–60%; the alternating feeding time of the two materials can be 2–20 min, preferably 5–10 min; the continued mixing time after feeding can be 1–15 min, preferably 3–8 min; the total processing time from the start of feeding to the completion of mixing can be 5–30 min, preferably 8–15 min.

[0027] In one specific embodiment, the mass ratio of powdered nutrients to liquid antibacterial components is 200:1, the powder particle size is 500-700 μm, the dynamic viscosity of the liquid antibacterial components is 20-50 mPa·s, the powder preheating temperature is 35°C, the rotation speed of the central shaft 13 and the centrifuge drum 111 rotating synchronously with it is about 240 r / min, the single batch filling rate is about 50%, the alternating feeding time is about 7 min, the mixing continues for about 5 min after feeding is completed, and the total processing time is about 12 min.

[0028] In summary, by adopting the above structure, the present invention has the following advantages compared with the prior art:

[0029] 1. In this invention, the alternating feeding assembly drives the turntable to rotate synchronously by the central shaft. The mechanical cooperation of the cam groove and the pulley drives the push-pull rod and the feed plate to slide back and forth, so that the two feed pipes are alternately connected according to a fixed rhythm, realizing the alternating feeding of powder and liquid at two stations. This can avoid the two components from directly colliding and causing agglomeration, which is beneficial to control the feeding sequence of the two components and effectively improve the uniformity of subsequent reactions and the stability of finished product batches.

[0030] 2. In this invention, the first and second feeding inclined frames and the diversion component allow the powder nutrients to fall directly into the first feeding inclined frame, while the liquid antibacterial component first falls into the second feeding inclined frame and is dispersed into multiple fine streams by the diversion channel before flowing into the first feeding inclined frame. The dispersed liquid flow washes over the powder components, allowing the liquid and powder to complete initial contact and mixing during the falling process. This breaks up the powder accumulation state, prevents the liquid from concentrating and wetting the powder to form wet clumps, and improves the uniformity of premixing. At the same time, the annular actuating frame rotates with the central shaft and intermittently pushes the extrusion seat. Combined with the elastic reset effect of multiple sets of V-shaped elastic support plates, this causes the first and second feeding inclined frames to vibrate continuously. Under the vibration, the two components are continuously dispersed and slide down at a uniform speed, which further enhances the contact and premixing effect of the powder and liquid. This also prevents the components from adhering and accumulating on the inclined surface, ensuring a smooth and continuous feeding process.

[0031] 3. In this invention, the centrifuge tube rotates at high speed with the central shaft to generate centrifugal force, which throws the premixed components evenly from the circumferential surface and the bottom discharge hole to the surrounding area, thereby achieving secondary dispersion and mixing of the components. Combined with the continuous stirring of the components at the bottom of the tank by the bottom stirring rack, the components in the tank form an overall circulation flow, ensuring that the antibacterial components are evenly loaded on the surface of the nutrient powder, which is beneficial to improving the uniformity of the final mixing reaction.

[0032] 4. In this invention, by setting up a first discharge assembly, a second discharge assembly, and a drive mechanism, the spiral blades push the powder components and the double-sided turbine blades push the liquid components. With the alternating feeding rhythm, uniform discharge is achieved, ensuring the stability of the feeding process and improving the overall production feeding efficiency. At the same time, a single drive motor is used in conjunction with a transmission structure of double pulleys and a transmission belt to synchronously drive the central shaft, the first transmission shaft, and the second transmission shaft to rotate. This realizes the synchronous linkage of multiple mechanisms for alternating feeding control, conveying of two components, and mixing in the tank. This simplifies the overall structure of the device, reduces equipment manufacturing costs and operating energy consumption, and ensures precise matching of the action rhythm of each mechanism.

[0033] 5. In this invention, the heating tube and inner liner set in the first feed hopper can uniformly preheat the stored powder nutrients. By moderately preheating the powder nutrients, it is beneficial to reduce the adverse effects of moisture on the powder's flowability, so that the powder maintains a good loose and flowable state, thereby improving the subsequent feeding and contact dispersion effect with liquid antibacterial components. At the same time, it is beneficial to reduce the adverse effects of moisture on the powder's flowability, avoid powder agglomeration, improve powder flowability, and ensure smooth feeding and mixing processes.

[0050] Please see Figures 1-11 This invention provides a feed nutrient antibacterial component compound mixing equipment with dual-station alternating feeding, including a reaction tank 1. A top cover 6 is fixedly installed on the top of the reaction tank 1, and two mounting seats 2 are fixedly installed in the middle of the top of the top cover 6. A first feed hopper 3 and a second feed hopper 5 with dual-station feeding are fixedly installed on both sides of the two mounting seats 2, respectively. The first feed hopper 3 is used to store powder nutrient components, and the second feed hopper 5 is used to store liquid antibacterial components. The bottom discharge ends of the first feed hopper 3 and the second feed hopper 5 are both fixed with a feed pipe 17 that passes through the top cover 6 and communicates with the top of the reaction tank 1.

[0051] A first mounting hole is provided at the center of the top of the reaction vessel 1 and the top cover 6, and at the middle of the mounting base 2. The inner wall of the first mounting hole is rotatably connected to a central shaft 13 via a sealed bearing. An alternating feeding assembly 9 is provided between the outer wall of the central shaft 13 and the two feed pipes 17, located inside the top cover 6. The alternating feeding assembly 9 includes a turntable 91 fixedly mounted on the central shaft 13. A cam groove 98 is provided on the top of the turntable 91. Pulleys 99 are slidably provided at both ends of the inner wall of the cam groove 98. The tops of the two pulleys 99 are rotatably connected to a push-pull rod 92 via a pin. An opening 9 is provided at the middle of each of the two feed pipes 17. 10. One end of each of the two push-pull rods 92 is fixed with a feed plate 93 that moves along the opening 910. The feed plate 93 has a feed groove 96 that corresponds to and communicates with the feed pipe 17. The cam groove 98 is a closed non-circular cam groove, and its radial distance from the central axis changes periodically at different circumferential positions. The two pulleys 99 are circumferentially offset and 180° apart, so that the two feed plates 93 are in an alternating communication state. When the central shaft 13 rotates, it drives the turntable 91 to rotate synchronously. Through the cooperation of the cam groove 98 and the pulley 99, the push-pull rod 92 drives the feed plate 93 to slide back and forth, so that the two feed grooves 96 alternately communicate with the corresponding feed pipes. The feed pipe 17 has aligned and connected flow channels, enabling alternating feeding at two stations. Two symmetrical annular sealing seats 94 are fixedly installed on the inner wall of the feed pipe 17, fitting against the upper and lower surfaces of the feed plate 93. The annular sealing seats 94 are connected to the feed trough 96. Two fixing plates 95 are fixed on both sides of the outer wall of the feed pipe 17, and sealing gaskets 97, respectively fitting against the upper and lower surfaces of the feed plate 93, are fixedly installed on the opposite surfaces of the two fixing plates 95. The central shaft 13 rotates continuously under driving force, synchronously driving the turntable 91 to rotate. The cam groove 98 at the top of the turntable 91 moves in a circular motion with the turntable 91, causing the two pulleys 99 inside the groove to reciprocate along the groove's trajectory. The movement is achieved by pulling the push-pull rod 92 horizontally via the pin shaft. The push-pull rod 92 drives the feeding plate 93 to slide back and forth along the opening 910 of the feed pipe 17. When the feeding groove 96 on the feeding plate 93 is aligned with the flow channel of the feed pipe 17, the feed pipe 17 on that side is open, and the material components fall downward into the reaction tank 1. When the feeding groove 96 is misaligned with the flow channel, the feed pipe 17 on that side is closed. The feeding plates 93 on both sides alternately open and close as the turntable 91 rotates, realizing alternating feeding at two stations. At the same time, the annular sealing seat 94 and the sealing gasket 97 are always in contact with the upper and lower surfaces of the feeding plate 93, maintaining a seal and preventing leakage during the sliding switching process.

[0052] A first discharge assembly 8 is provided inside the first feed hopper 3, and a second discharge assembly 14 is provided inside the second feed hopper 5. A drive mechanism 4 is provided on the top of the first discharge assembly 8, the second discharge assembly 14, and the central shaft 13. The first discharge assembly 8 includes a second mounting hole opened in the middle of the top of the first feed hopper 3, and a first drive shaft 81 is rotatably connected to the inner wall of the second mounting hole through a sealed bearing. A spiral blade 82 is fixedly installed on the outer wall of the first drive shaft 81. The second discharge assembly 14 includes a third mounting hole opened in the middle of the top of the second feed hopper 5, and a second drive shaft 141 is rotatably connected to the inner wall of the third mounting hole through a sealed bearing. A double-sided turbine blade 142 is fixedly installed at the bottom of the second drive shaft 141. The blades of the double-sided turbine blade 142 are set at a preset tilt angle, with the tilt angle ranging from 15° to 35°. The rotation direction matches the rotation direction of the second drive shaft 141. When the blades rotate, they form an axial flow towards the downward feed pipe 17, pushing the liquid antibacterial component in the second feed hopper 5 downward at a uniform speed. The drive mechanism 4 includes a drive frame 41 fixedly installed at the top of the first feed hopper 3 and the second feed hopper 5. The first drive shaft 81, the second drive shaft 141, and the central shaft 13 are all fixedly installed with double pulleys at the top of the drive frame 41. A transmission belt 43 connects the pulleys. The diameter of the double pulleys at the top of the central shaft 13 is smaller than the diameter of the double pulleys at the top of the first transmission shaft 81 and also smaller than the diameter of the double pulleys at the top of the second transmission shaft 141. A preset transmission ratio is formed by the difference in pulley diameters. The rotational speed of the central shaft 13 is 2 to 4 times that of the transmission shafts, so that the central shaft 13 obtains a higher working speed than the first transmission shaft 81 and the second transmission shaft 141. The diameters of the double pulleys of the first transmission shaft 81 and the second transmission shaft 141 can be the same or different to match the different feed flow requirements of powder and liquid. A drive motor 42 is fixedly installed on the top of the drive frame 41, and the output shaft of the drive motor 42 is connected to the central shaft 13. The top of 3 is fixedly connected. After the drive motor 42 starts, it drives the central shaft 13 to rotate. The double pulleys at the top of the central shaft 13 drive the double pulleys at the top of the first drive shaft 81 and the second drive shaft 141 on both sides to rotate synchronously through the transmission belt 43. This drives the first drive shaft 81 and the second drive shaft 141 to rotate synchronously. The first drive shaft 81 drives the spiral blades 82 to rotate, pushing the powder components in the first feed hopper 3 downward at a uniform speed to avoid powder blockage. The second drive shaft 141 drives the double-sided turbine blades 142 to rotate, pushing the liquid components in the second feed hopper 5 downward at a uniform speed to ensure stable flow and make the discharge rhythm and the alternating feed rhythm perfectly matched.

[0053] Inside the reaction vessel 1, a first mixing component 10 and a second mixing component 11 are arranged sequentially from top to bottom. Both the first mixing component 10 and the second mixing component 11 are linked to the central shaft 13. The first mixing component 10 includes a first hinge seat 101 and a second hinge seat 106 fixedly installed on both sides of the inner wall of the top of the reaction vessel 1. A first feeding inclined frame 102 is rotatably connected to the first hinge seat 101 via a pin. A second feeding inclined frame 104 is rotatably connected to the second hinge seat 106 via a pin. The bottom end of the second feeding inclined frame 104 is located inside the first feeding inclined frame 102. Third V-shaped elastic support plates 1012 are fixedly installed on both sides of the bottom of the second feeding inclined frame 104 and the inner walls of both sides of the first feeding inclined frame 102. The top two sides of the first feeding inclined frame 102... A second V-shaped elastic support plate 109 is fixedly installed on both sides of the top inner wall of the reaction vessel 1, and a first V-shaped elastic support plate 105 is fixedly installed on both sides of the top of the second feeding inclined frame 104 to the top inner wall of the reaction vessel 1. The second feeding inclined frame 104 has a movable hole 1010 for the central shaft 13 to pass through, and a leak-proof cylinder 107 is fixed on the top of the movable hole 1010. The bottom end of the second feeding inclined frame 104 has a lower drain 1011 for the powder nutrients to fall into the first feeding inclined frame 102, and a diversion component is provided on the inner wall of the second feeding inclined frame 104 near the lower drain 1011. An extrusion seat 103 is fixedly installed on the bottom of the first feeding inclined frame 102, and several support rods 1015 are fixed on the outer wall of the central shaft 13. One end of 1015 is fixed with the same annular actuating frame 1016. The annular actuating frame 1016 is located below the extrusion seat 103. The annular actuating frame 1016 has a continuous alternating convex and concave shape. The outlet of the feed pipe 17 corresponding to the first feed hopper 3 corresponds vertically to the lower drain 1011. The outlet of the feed pipe 17 corresponding to the second feed hopper 5 is located above the second discharge inclined frame 104. When rotating, it intermittently pushes the extrusion seat 103, causing the two discharge inclined frames to vibrate. The diversion component includes an inclined seat 108 fixedly installed on the inner wall of the second discharge inclined frame 104. Several equally spaced diversion plates 1013 are fixed on the top of the inclined seat 108. The gap between two adjacent diversion plates 1013 is designed as a diversion groove 1014. The second mixing component 11 includes a fixed... The centrifuge cylinder 111 is located on the outer wall of the central shaft 13. Several support columns are fixed to the top of the centrifuge cylinder 111 and the bottom of the annular agitator 1016. Several annularly distributed discharge holes 112 are opened on the circumference and bottom of the centrifuge cylinder 111. An agitator 113 is fixedly installed at the bottom of the central shaft 13. During the alternating feeding process, the powder nutrients fall from the corresponding feed pipe 17 and directly fall onto the inclined surface of the first feeding inclined frame 102 through the lower drain 1011. The liquid antibacterial components fall from the corresponding feed pipe 17 and fall onto the inclined surface of the second feeding inclined frame 104. As they slide down the inclined surface, they pass through the diversion component on the inclined seat 108 and are separated into multiple fine streams by the multi-group diversion plate 1013. After being dispersed by the diversion groove 1014, they flow into the first feeding inclined frame 102.The dispersed liquid flow washes over the powder nutrients, allowing them to initially mix. Simultaneously, as the central shaft 13 rotates, it drives the annular actuating frame 1016 to rotate synchronously via the support rod 1015. When the protruding part on the surface of the annular actuating frame 1016 rotates to below the extrusion seat 103, it pushes the extrusion seat 103 upwards, causing the first and second feeding inclined frames 102 and 104 to swing upwards around the pin axis of their corresponding mounting seats. After the protruding part has rotated, the elastic force of the first V-shaped elastic support plate 105, the second V-shaped elastic support plate 109, and the third V-shaped elastic support plate 1012 drives the two feeding inclined frames. The rapid reset and repeated vibrations cause the components to tumble, disperse, and slide down the inclined plane at a uniform speed, fully premixing them before they fall into the centrifuge cylinder 111 below. The centrifuge cylinder 111 rotates at high speed synchronously with the central shaft 13, generating centrifugal force that evenly ejects the premixed material from the circumferential surface and the discharge holes 112 at the bottom into the lower space of the reaction vessel 1. Simultaneously, the agitator 113 at the bottom of the central shaft 13 rotates synchronously with the shaft, continuously stirring the material at the bottom of the reaction vessel 1, creating a circulating flow and ensuring sufficient contact between the two components to complete the compounding reaction.

[0054] In this invention, an inner liner 15 is fixedly installed on the inner wall of the first feed hopper 3, and a heating tube 16 is fixedly installed at the gap between the outer wall of the inner liner 15 and the inner wall of the first feed hopper 3. The heating tube 16 is electrically connected to a controller for preheating the powder nutrients in the inner liner 15 to promote the subsequent compound reaction of the powder nutrients and the liquid antibacterial components.

[0055] In this invention, both the first feed hopper 3 and the second feed hopper 5 are provided with feed pipes 18 at their tops, and the tops of the feed pipes 18 are provided with sealing caps. The bottom discharge end of the reaction tank 1 is fixedly installed with a discharge valve 12, and the bottom outer wall of the reaction tank 1 is fixedly installed with a support frame 7. The corresponding raw materials can be added to the two feed hoppers through the feed pipes 18 respectively. After completion, the sealing caps are closed to keep the inside of the feed hoppers sealed. After the compound reaction is completed, the discharge valve 12 is opened, and the finished product is discharged from the bottom of the reaction tank 1. The support frame 7 plays a supporting and fixing role for the entire reaction tank 1, ensuring the structural stability of the device during operation.

[0056] In summary, the working principle of the present invention is as follows: During operation, the powdered nutrient components and the liquid antibacterial active components are first introduced into the first feed hopper 3 and the second feed hopper 5 through two feed pipes 18 respectively. The heating pipe 16 in the first feed hopper 3 can preheat the powdered raw materials in the inner liner 15 to enhance the powder activity and accelerate the reaction rate.

[0057] Next, the drive motor 42 outputs power to drive the central shaft 13 to rotate. At the same time, the double pulleys in the drive frame 41 and the transmission belt 43 synchronously drive the first transmission shaft 81 and the second transmission shaft 141 to rotate. The first transmission shaft 81 drives the spiral blades 82 to rotate, pushing the powder nutrients in the first feed hopper 3 to the corresponding feed pipe 17. The second transmission shaft 141 drives the double-sided turbine blades 142 to rotate, pushing the liquid antibacterial components in the second feed hopper 5 to the corresponding feed pipe 17. The rotation of the central shaft 13 also drives the turntable 91 to rotate synchronously. Through the cooperation of the cam groove 98 and the pulley 99, the two push rods 92 are driven to perform horizontal reciprocating motion, causing the two feed plates 93 to slide back and forth along the opening 910 in the feed pipe 17. This allows the feed trough 96 to alternately align and connect with the flow channels of the feed pipes 17 on both sides. With the cooperation of the annular sealing seat 94 and the sealing gasket 97, the sealing performance is maintained during the sliding process, so that the powder and liquid components fall into the reaction tank 1 alternately at a fixed rhythm.

[0058] The powdered nutrients fall along the feed pipe 17 and the lower drain 1011 onto the first feeding inclined frame 102, while the liquid antibacterial components flow along the feed pipe 17 onto the second feeding inclined frame 104. Then, they slide down the inclined surface, pass through the diversion plate 1013 and diversion groove 1014 on the inclined seat 108, are dispersed into multiple fine streams, and then flow into the first feeding inclined frame 102. On the one hand, this washes the powdered nutrients on the first feeding inclined frame 102, and on the other hand, it allows the two components to be initially mixed. At the same time, the central shaft 13 drives the annular actuating frame 1016 to rotate continuously through the support rod 1015. Using its convex and concave contours, it intermittently pushes the extrusion seat 103. With the elastic restoring effect of the first V-shaped elastic support plate 105, the second V-shaped elastic support plate 109, and the third V-shaped elastic support plate 1012, the first feeding inclined frame 102 and the second feeding inclined frame 104 reciprocate, so that the two components are fully premixed during the vibration and falling.

[0059] The premixed components fall into the centrifuge cylinder 111. The centrifuge cylinder 111, which rotates synchronously with the central shaft 13, generates centrifugal force, which throws the components evenly outward from the discharge holes 112 on the circumferential surface and the bottom. At the same time, the stirring rack 113 at the bottom of the central shaft 13 continuously stirs the components at the bottom of the reaction vessel 1, so that the two components can fully contact each other to complete the compound reaction. The finished product after the reaction is completed is finally discharged through the discharge valve 12.

[0060] This embodiment provides a specific method for using a dual-station alternating feeding feed nutrient antibacterial component compound mixing equipment.

[0061] Before starting work, determine the batch feed amount based on the composition of the material to be processed, so that the total volume of the powder nutrients and liquid antibacterial components after being added to the reaction tank 1 accounts for about 50% of the effective volume of the reaction tank 1, thereby reserving sufficient space for material dispersion and circulation inside the reaction tank 1.

[0062] In this embodiment, the powdered nutrient component uses a composite nutrient raw material with a particle size of 500–700 μm, and the liquid antibacterial component has a dynamic viscosity of 20–50 mPa·s at the operating temperature, preferably about 30–40 mPa·s. The powdered nutrient component and the liquid antibacterial component are added to the first feed hopper 3 and the second feed hopper 5 respectively at a mass ratio of 200:1. Based on this mass ratio, the liquid antibacterial component accounts for approximately 0.50% of the total mass of the powdered nutrient component and the liquid antibacterial component.

[0063] For example, when the mass of the powdered nutrient component added to the first feed hopper 3 is 20 kg, the mass of the liquid antibacterial component added to the second feed hopper 5 is 0.10 kg, or 100 g, and the mass ratio of the two is 200:1. In practical applications, the batch feed mass can be proportionally scaled up or down according to the effective volume of the reaction tank 1 and the bulk density of the powdered material, while maintaining the preset mass ratio of the powdered nutrient component to the liquid antibacterial component.

[0064] After feeding is completed, the heating tube 16 located inside the first feed hopper 3 is activated to preheat the powder nutrients in the inner liner 15, raising the powder temperature to approximately 35°C. This moderate preheating reduces the adverse effects of moisture on the powder's flowability, maintaining a good loose and flowable state, and facilitating the subsequent wetting and dispersion of the liquid antibacterial components on the powder particle surface. The heating tube 16 is located on the outside of the inner liner 15 of the first feed hopper 3 for preheating the powder nutrients.

[0065] Once the powdered nutrients reach the preset temperature, the drive motor 42 is activated. The drive motor 42 drives the central shaft 13 to rotate at a speed of approximately 240 r / min, and drives the first drive shaft 81 and the second drive shaft 141 to rotate via the double pulleys and transmission belt 43 set in the drive frame 41. The first drive shaft 81 further drives the spiral blades 82 to rotate, conveying the powdered nutrients in the first feed hopper 3 to the corresponding feed pipe 17; the second drive shaft 141 drives the double-sided turbine blades 142 to rotate, conveying the liquid antibacterial components in the second feed hopper 5 to the corresponding feed pipe 17.

[0066] During the rotation of the central shaft 13, the turntable 91 is rotated synchronously. Through the cooperation of the cam groove 98 and the pulley 99, the two push-pull rods 92 are driven to reciprocate. This further drives the two feed plates 93 to slide back and forth along the corresponding openings 910, so that the two feed troughs 96 are alternately connected to the flow channels of the corresponding feed pipes 17 according to the preset rhythm, thereby allowing the powder nutrients and liquid antibacterial components to enter the reaction tank 1 alternately according to the predetermined sequence.

[0067] In this embodiment, the alternating feeding process of the two materials lasts for approximately 7 minutes. Alternating feeding means that the powdered nutrient components and the liquid antibacterial components enter the reaction tank 1 in stages according to a preset rhythm, rather than meaning that the mass of the two materials entering each time is equal. Through the feeding capacity of the first discharge assembly 8 and the second discharge assembly 14, as well as the corresponding feeding structure, the overall mass ratio of the powdered nutrient components to the liquid antibacterial components is maintained at approximately 200:1 throughout the feeding stage.

[0068] During the alternating feeding process, the powder nutrients input from the first feed hopper 3 fall onto the first feeding inclined frame 102 through the corresponding feed pipe 17 and the lower drain 1011; the liquid antibacterial components input from the second feed hopper 5 first fall onto the second feeding inclined frame 104 and flow downwards along the second feeding inclined frame 104. When the liquid antibacterial components pass through the inclined seat 108, the diversion channel 1014 formed by the multi-component diversion plate 1013 and adjacent diversion plates 1013 disperses the relatively concentrated liquid into multiple liquid streams, which then enter the first feeding inclined frame 102 and come into contact with the powder nutrients thereon, thereby preventing the liquid antibacterial components from concentrating and impacting the powder in the same area.

[0069] Meanwhile, the central shaft 13 drives the annular actuating frame 1016 to rotate via the support rod 1015, and the protruding part of the annular actuating frame 1016 intermittently pushes against the extrusion seat 103. Under the elastic restoring action of the first V-shaped elastic support plate 105, the second V-shaped elastic support plate 109, and the third V-shaped elastic support plate 1012, the first feeding inclined frame 102 and the second feeding inclined frame 104 continuously generate reciprocating vibration, so that the powder nutrients and the liquid antibacterial components after diversion continuously disperse, turn over, and contact each other during the downward movement, completing the first stage of dynamic premixing.

[0070] The material premixed by the first mixing component 10 further falls into the centrifuge cylinder 111. Since the centrifuge cylinder 111 is fixedly mounted on the outer wall of the central shaft 13, in this embodiment, the centrifuge cylinder 111 and the central shaft 13 rotate synchronously, with a rotation speed of approximately 240 r / min. The rotation of the centrifuge cylinder 111 generates centrifugal force, causing the premixed material entering the centrifuge cylinder 111 to be dispersed and discharged into different directions within the reaction vessel 1 through the discharge holes 112 provided on the circumferential surface and at the bottom, thereby performing a second stage of dispersion and mixing of the premixed material.

[0071] While the centrifuge 111 is performing secondary dispersion, the agitator 113 located at the bottom of the central shaft 13 rotates synchronously with the central shaft 13, continuously agitating the material falling into the lower part of the reaction tank 1, so that the material dispersed through the discharge holes 112 at different positions further forms an overall circulation flow in the reaction tank 1, thereby improving the uniformity of the distribution of liquid antibacterial components in the powder nutrients.

[0072] After the powdered nutrients and liquid antibacterial components have been fed alternately for about 7 minutes, the drive motor 42 continues to work, so that the central shaft 13, centrifuge cylinder 111 and stirring rack 113 continue to run for about 5 minutes to further centrifuge, disperse and circulate the materials in the reaction tank 1.

[0073] Therefore, in this embodiment, the total processing time from the start of alternating feeding to the completion of final mixing is approximately 12 minutes, of which the alternating feeding and synchronous premixing stage is approximately 7 minutes, and the continued mixing stage after all materials have been fed is approximately 5 minutes. After mixing is completed, the drive motor 42 is stopped, and the discharge valve 12 at the bottom of the reaction tank 1 is opened to discharge the material after the compounding process from the reaction tank 1.

[0074] In light of current practical needs, the above-described embodiments of this invention are not limited to these specific implementations. Any changes made within the scope of knowledge possessed by those skilled in the art, without departing from the concept of this invention, still fall within the protection scope of this invention.
