Description

Technical Field

[0001] This invention relates to the field of feed preparation technology, and in particular to a feed pellet maturation and sterilization device for livestock feed production. Background Technology

[0002] The livestock feed pellet maturation and sterilization device utilizes a combination of 80-100℃ high-temperature maturation and physical sterilization techniques to kill pathogenic microorganisms such as Salmonella, Escherichia coli, and mold in feed, effectively blocking the transmission routes of livestock and poultry diseases and providing reliable protection for livestock biosecurity. As a core piece of equipment in the modern feed industry, this device can simultaneously improve feed nutrient conversion rate and large-scale production efficiency, making it a key technological tool for livestock and poultry farms and feed processing enterprises to achieve quality upgrades and cost reductions.

[0003] Currently, in the maturation and sterilization process of livestock feed pellets, the heat source is mostly located on the outside of the cylinder. When a large amount of feed pellets are put into the cylinder, the pellets near the heat source can effectively heat up and complete maturation and sterilization; however, the feed pellets located in the middle of the cylinder cannot be fully heated and sterilized due to accumulation issues. This may result in some uncooked feed being consumed by poultry and other animals, thereby increasing their risk of disease. Although stirring methods can agitate the feed to some extent, there are still dead zones in the stirring, and the problem of insufficient heating of the feed has not been completely solved. Summary of the Invention

[0004] This invention proposes a feed pellet cooking and sterilization device for livestock feed production, which has the advantage of feed circulation cooking and sterilization, and solves the problem mentioned in the background art that the presence of dead corners in the stirring leads to incomplete cooking and sterilization of feed in certain areas.

[0005] To achieve the above objectives, this application adopts the following technical solution: a feed pellet maturation and sterilization device for livestock feed production, comprising: a frame, with a sterilization barrel fixedly mounted on its surface, and an outer cylinder fixedly mounted in the middle of the sterilization barrel using a support; a baffle ring screen, installed on the top of the outer cylinder, with a rectangular groove on its side limiting and guiding a guide arm, and a rotating core fixed at one end of the guide arm; a bottom cylinder, fixed to the bottom of the support, with a drive main shaft limited by a shaft frame in the middle of the inner side of the bottom cylinder, and the top of the drive main shaft being driven by a reduction gearbox and connected to a conveying auger. The auger is fixedly connected to the inner side of the rotating core; the fan blades are fixed to the outer side of the drive shaft; the heating ring assembly is fixed to the inner wall of the sterilization tank; the drive assembly is fixed to the surface of the frame, and its output end is connected to the drive shaft for transmission; when the drive assembly drives the drive shaft to rotate, the drive shaft drives the auger to rotate, causing the feed in the outer cylinder to tumble up and down; the drive shaft synchronously drives the fan blades to rotate, so that the hot air heated by the heating ring assembly is delivered to the auger, realizing the cooking and sterilization of the feed on the auger.

[0006] Furthermore, a feeding seat is fixedly connected to the top of the sterilization tank, and a feeding pipe is movably installed at the bottom of the feeding seat.

[0007] Furthermore, a discharge seat is fixedly installed on the surface of the frame, located below the sterilization tank, and the discharge seat is located below the bottom cylinder.

[0008] Furthermore, a sieve plate is fixedly installed in the middle of the inner side of the sterilization barrel.

[0009] Furthermore, the bottom of the feed pipe is coaxially and fixedly connected to the top of the conveying auger. A planetary gear reduction assembly is movably installed on the top inner side of the sterilization tank. The planetary gear reduction assembly consists of a central wheel, planetary gears, and a gear ring frame. The central wheel is movably installed on the bottom of the feed seat. The central wheel and the feed pipe are fitted together and connected in transmission. The planetary gears are arranged on the outer side of the central wheel. A gear ring frame is movably and sealed on the top inner side of the sterilization tank, and the gear ring frame meshes with the planetary gears for transmission. A limit component is fixedly installed at the bottom of the gear ring frame, and a blockage-clearing pusher is installed at the bottom of the limit component. The screen is C-shaped, and a slag discharge seat located at the notch of the screen is fixedly installed on the side of the sterilization tank.

[0010] Furthermore, the limiting component includes a T-shaped rod and a sleeve. The T-shaped rod is fixedly installed on the gear ring frame, and the sleeve is threadedly connected to the surface of the unblocking push block. A tension spring is provided between the sleeve and the T-shaped rod.

[0011] Furthermore, the top of the baffle ring screen is fixedly connected to the gear ring frame of the planetary gear reduction assembly, and a connecting arm is movably installed on the side of the baffle ring screen, with both ends of the connecting arm being movably connected to the top of the rotating core and the top of the unblocking push block, respectively.

[0012] Furthermore, the planetary gear reduction assembly provides elastic torque transmission between the central wheel and the feed tube.

[0013] Furthermore, multiple limiting grooves are arranged at equal angles on the side of the feed pipe, and an elastic limiting component is installed at the bottom of the central wheel of the planetary gear reduction assembly, which abuts against the limiting groove.

[0014] Furthermore, a disengagement ramp is provided on one side of the unblocking push block, and a reset ramp and a stop ramp are provided on the opposite side of the disengagement ramp, with the stop ramp located below the reset ramp.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention provides a feed pellet maturation and sterilization device for livestock feed production. It features a rotating core installed inside an outer cylinder, with a conveying auger in the center of the core that flips the feed from the bottom of the outer cylinder to the top. This causes the feed in the outer cylinder to move up and down in an orderly manner. Simultaneously, as the conveying auger transports the feed upwards, the fan blades drive the heated airflow, heated by the heating ring assembly, to be transported synchronously. This ensures that the heated airflow can fully contact the feed. With the continuous and orderly flipping of the conveying auger and the continuous upward transport of the heated airflow, the effect of feed circulation maturation and sterilization is achieved.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1, please refer to Figures 1-3 It can be seen that the frame 1 is placed in the required area using support legs, providing stable support for the entire device. A sterilization tank 2, which is a cylindrical shape with a through-hole in the middle, is fixedly mounted on the surface of the frame 1. Combined with... Figures 2-3 It can be seen that the sterilization tank 2 has an outer cylinder 7 fixedly installed in the middle using a bracket, and a baffle screen 9 is movably installed on the top of the outer cylinder 7. Figure 4 and Figure 7 As shown, the side of the baffle ring screen 9 has multiple vertically arranged rectangular grooves. Guide arms 131 are movably installed in these rectangular grooves, and a rotating core 13, coaxially arranged with the outer cylinder 7, is fixedly installed at one end of each guide arm 131. It should be noted that in this embodiment, a gap needs to be maintained between the bottom of the rotating core 13 and the bottom of the outer cylinder 7 to ensure that feed between the rotating core 13 and the outer cylinder 7 can flow through this gap to the bottom of the rotating core 13. For feed input, from... Figures 2-4 It can be seen that the top of the sterilization tank 2 is fixedly connected to the feed seat 201, and the feed seat 201 is in the shape of an upward-opening trumpet. The bottom of the feed seat 201 is movably installed with the feed pipe 11 located in the inner area of ​​the baffle ring screen 9. By pouring livestock feed into the feed seat 201, the feed can enter the outer cylinder 7 through the feed seat 201 and the feed pipe 11. Subsequently, the feed is cooked and sterilized inside the outer cylinder 7.

[0029] from Figures 2 to 4 It can be seen that the bracket used to fix the outer cylinder 7 has a bottom cylinder 6 that is fastened to the bottom cylinder 6 by a flange, and a drive main shaft 5 that is limited by a shaft bracket in the middle of the inner side of the bottom cylinder 6. A cylindrical reduction gearbox that is coaxially fastened to the top of the shaft bracket is fixedly installed. Figure 3 As shown in section A, a conveying auger 16 located inside the rotating core 13 is coaxially and securely mounted on the top of the cylindrical reduction gearbox. The top of the conveying auger 16 is higher than the rotating core 13, and the bottom is below the rotating core 13. Generally, the bracket for supporting the outer cylinder 7 is slidably connected to the outer side of the conveying auger 16. When the feed between the rotating core 13 and the outer cylinder 7 flows to the area below the rotating core 13, it is supported and guided by the bracket and the area between the bottom of the rotating core 13, so that the material is finally conveyed to the outside of the conveying auger 16. In addition, a fan blade 17 located below the shaft frame is fixedly mounted on the outer side of the drive shaft 5. When the drive shaft 5 drives the fan blade 17 to rotate, it not only uses the conveying auger 16 to convey the feed at the bottom of the rotating core 13 upward, but also causes the airflow at the bottom of the bottom cylinder 6 to be conveyed upward along the conveying auger 16 through the rotation of the fan blade 17. A drive assembly 3 is fixedly mounted on the surface of the frame 1, and the output shaft of the drive assembly 3 is connected to the drive shaft 5 through a transmission assembly, which is preferably a sprocket or belt drive. The drive assembly 3 is powered by mains electricity and is regulated by the control system to ensure that the drive assembly 3 can drive the drive spindle 5 to rotate synchronously according to the transmission assembly.

[0030] Combination Figure 2 and Figure 3 It can be seen that a discharge seat 202 is fixedly installed on the surface of the frame 1, located below the sterilization tank 2, and the discharge seat 202 is directly below the bottom cylinder 6. When feed is conveyed downwards from the conveying auger 16, the feed falls into the discharge seat 202 after being guided by the bottom cylinder 6. The discharge seat 202 can then convey the cooked and sterilized feed outwards. Under normal operation, the discharge seat 202 is kept in a closed state using valves or other means. Furthermore, from... Figure 2 and Figure 3 It can be seen that a heating ring component 4 is fixedly installed on the inner wall of the sterilization tank 2. Powered by mains electricity and regulated by the control system, the heating ring component 4 can heat the surrounding air.

[0031] In this embodiment, during actual operation, the feed is poured in from the feed seat 201, guided by the feed pipe 11, and flows into the inner cavity of the outer cylinder 7. After the feed is poured in, the inlet of the feed seat 201 is sealed. At this time, the inner cavity of the sterilization tank 2 is relatively sealed, and the air in the top area of ​​the outer cylinder 7 is connected to the inner cavity of the sterilization tank 2 through the rectangular groove on the baffle ring screen 9.

[0032] The control system activates the heating ring assembly 4 and raises it to the required temperature, which is adjusted according to actual needs. The drive assembly 3 drives the drive shaft 5 to rotate forward through the transmission assembly. When the drive shaft 5 rotates forward, the fan blades 17 transport the airflow from the bottom of the bottom cylinder 6 upward. At the same time, the drive shaft 5, after being driven by the cylindrical reduction gearbox, causes the conveying auger 16 to rotate synchronously. During the rotation of the conveying auger 16, the feed flowing downward between the rotating core 13 and the outer cylinder 7 is conveyed from the bottom of the rotating core 13 into the conveying auger 16. The conveying auger 16 causes the feed to turn upward, and this cycle continues, ensuring that the feed in the inner cavity of the outer cylinder 7 can be fully turned up and down.

[0033] Meanwhile, as the auger 16 conveys the feed upwards, the fan blades 17 draw in hot air from the bottom of the bottom cylinder 6, which has been heated by the heating ring assembly 4, and propel it upwards along the bottom cylinder 6, simultaneously flowing upwards through the auger 16. During this process, the hot air moves upwards along the auger 16, ensuring that the feed conveyed by the auger 16 undergoes focused cooking and sterilization. Combined with the auger 16 continuously tumbling the feed inside the outer cylinder 7, the hot air comes into contact with all the feed, ensuring that all feed in the outer cylinder 7 undergoes cooking and sterilization. Finally, the airflow is conveyed into the sterilization tank 2 through the rectangular groove of the baffle ring screen 9. As the bottom of the bottom cylinder 6 continues to draw in air, the airflow above the sterilization tank 2 is heated again by the heating ring assembly 4, and this cycle continues, ensuring that both the hot air and the feed are constantly tumbled.

[0034] After the feed processing is completed, the discharge seat 202 is opened and the drive component 3 is rotated in reverse at a low speed, thereby forcing the conveying auger 16 to rotate in reverse. When the conveying auger 16 rotates in reverse, the feed at the bottom of the outer cylinder 7 is continuously conveyed downward and finally discharged outward from the discharge seat 202.

[0035] Example 2 is a further improvement on Example 1. Please refer to Example 1. Figure 2 and Figure 3 It can be seen that a sieve disc 8 is fixedly installed in the middle of the inner side of the sterilization tank 2, and is arranged in a sleeve on the outer side of the outer cylinder 7. The filter diameter of the sieve disc 8 is smaller than the rectangular groove on the baffle ring screen 9, and the width of the rectangular groove is relatively smaller than that of normal feed particles. In this way, during the feed cooking and sterilization process, after the feed is discharged from the top of the rotating core 13 by the conveying auger 16, the airflow is discharged outward simultaneously. As the airflow flows, the granular feed falls into the outer cylinder 7, while the broken particles pass through the rectangular groove of the baffle ring screen 9 with the airflow, and are filtered when passing through the sieve disc 8. Ultimately, this method ensures that the processed feed particles have a relatively uniform particle size, meeting the requirements for use.

[0036] Based on this, in order to achieve debris collection, combined with Figures 2-4 It can be seen that the bottom of the feed pipe 11 is coaxially and fixedly connected to the top of the conveying auger 16, so that the conveying auger 16 can drive the feed pipe 11 to rotate synchronously. A planetary gear reduction assembly 10 is movably installed on the top inner side of the sterilization tank 2. More specifically, the planetary gear reduction assembly 10 mainly consists of a central wheel, three planetary gears, and a gear ring frame. The central wheel is movably installed on the bottom of the feed seat 201, and the central wheel and the feed pipe 11 are fitted together and connected for transmission. The three planetary gears are arranged at equal angles on the outer side of the central wheel, and the three planetary gears are also movably installed on the bottom of the feed seat 201. A gear ring frame is movably and sealed on the top inner side of the sterilization tank 2, and the gear ring frame meshes with the planetary gears for transmission. More importantly, combined with Figure 4 As shown, B is the gear ring frame. The bottom of the gear ring frame is fixedly installed with a limiting component 15, and the bottom of the limiting component 15 is equipped with a block-clearing pusher 12. In this second embodiment, the bottom of the block-clearing pusher 12 is in sliding contact with the surface of the screen plate 8.

[0037] Combination Figure 3 and Figure 7 It can be seen that the sieve plate 8 is shaped like a "C", and the slag discharge seat 203 located at the notch of the sieve plate 8 is fixedly installed on the side of the sterilization barrel 2. Under normal circumstances, the slag discharge seat 203 is in the closed state.

[0038] In this second embodiment, the sieve disc 8 filters the debris particles, as described above. During this process, the conveying auger 16 drives the gear ring frame in the planetary gear reduction assembly 10 to rotate via the feed pipe 11. The rotation direction of the gear ring frame is opposite to that of the conveying auger 16. As the gear ring frame rotates, the limiting component 15 causes the unblocking pusher 12 to slide along the surface of the sieve disc 8, thereby scraping off the debris accumulated on the surface of the sieve disc 8. When the unblocking pusher 12 pushes the debris to the notch of the sieve disc 8, the debris falls into the slag discharge seat 203 for buffering. As the unblocking pusher 12 continues to rotate, the debris accumulated on the sieve disc 8 is continuously scraped into the slag discharge seat 203 for buffering. After processing is complete, the slag discharge seat 203 opens, discharging the debris. Since the debris can be reused, the collected debris can be used again for the preparation of feed pellets.

[0039] Example 3 is a further improvement on Example 2, more specifically, combined with Figure 7 and Figure 8 As shown, the limiting component 15 includes a T-shaped rod and a sleeve. The T-shaped rod is fixedly installed on the gear ring frame, and the sleeve is threadedly connected to the surface of the unblocking push block 12. A tension spring is provided between the sleeve and the T-shaped rod. Under the action of the tension spring, the unblocking push block 12 always tends to move downward.

[0040] Moreover, from Figures 2-4It can be seen that there is a gap between the rotating core 13 and the outer cylinder 7, which allows feed of the appropriate particle size to pass through. Furthermore, since the rotating core 13 is movably connected to the baffle ring screen 9, and the top of the baffle ring screen 9 is fixedly connected to the gear ring frame of the planetary gear reduction assembly 10, when the planetary gear reduction assembly 10 drives the baffle ring screen 9 to rotate, the guide arm 131 drives the rotating core 13 and the outer cylinder 7 to rotate synchronously relative to each other. This relative rotation of the two achieves the compression and separation of feed particles that are stuck together. It should be noted that before the feed is dried, some feed particles are stuck together due to moisture and other factors. As the feed is dried, it dehydrates, making it easier to separate the feed particles. Furthermore, from... Figure 3 and Figure 4 It can be seen that a connecting arm 14 is movably installed on the side of the baffle ring screen 9, and the two ends of the connecting arm 14 are movably installed on the top of the rotating core 13 and the top of the unblocking push block 12, respectively. In this way, when the unblocking push block 12 moves up and down, the rotating core 13 can move up and down within a certain range by the traction of the connecting arm 14 and the guidance of the guide arm 131.

[0041] More importantly, in this third embodiment, the elastic transmission torque between the central wheel of the planetary gear reduction assembly 10 and the feed pipe 11, specifically, in conjunction with... Figure 5 and Figure 6 It can be seen that multiple limiting grooves 110 are arranged at equal angles on the side of the feed pipe 11. The cross-sectional shape of the limiting grooves 110 is "V" shaped, and an arc-shaped protrusion is provided on the side of the feed pipe 11 and around the outer periphery of the limiting grooves 110. An elastic limiting component 18 is installed at the bottom of the central wheel of the planetary gear reduction assembly 10, which abuts against the limiting groove 110. The elastic limiting component 18 is mainly composed of a push rod and a spring. The push rod is movably installed between the push rod and the central wheel, and a spring is installed between the push rod and the central wheel. Pushed by the spring, the push rod abuts against the limiting groove 110. When the torque between the planetary gear reduction assembly 10 and the feed pipe 11 is too large, the push rod in the elastic limiting component 18 can disengage from the limiting groove 110. Furthermore, due to the presence of the arc-shaped protrusion, the push rod also needs to overcome a certain torque strength when entering the limiting groove 110.

[0042] Combination Figure 8 It can be seen that the unblocking push block 12 is provided with a disengagement inclined section 121 on one side, and a reset inclined section 122 and a stop straight section 123 are provided on the opposite side of the disengagement inclined section 121. The stop straight section 123 is located below the reset inclined section 122. When the unblocking push block 12 passes through the notch of the screen plate 8, the disengagement inclined section 121 moves along the end of the screen plate 8, so that the unblocking push block 12 that has fallen into the notch of the screen plate 8 can be restored and pressed against the surface of the screen plate 8.

[0043] The working principle of this third embodiment is as follows:

[0044] Feed is poured into the inner cavity of the outer cylinder 7 through the feed seat 201 and the feed pipe 11, and the feed flows into the inner cavity of the outer cylinder 7 through the bottom opening of the feed pipe 11.

[0045] The control system drives the drive assembly 3 to rotate in the forward direction. The drive assembly 3 uses the transmission assembly to make the drive spindle 5 rotate. The drive spindle 5 synchronously drives the connecting arm 14, the cylindrical gear reducer, the conveying auger 16, the feed pipe 11, and the planetary gear reducer assembly 10 to rotate. The gear ring frame on the planetary gear reducer assembly 10 synchronously drives the baffle ring screen 9 and the unblocking push block 12 on the limit assembly 15 to rotate.

[0046] like Figure 3 As shown, when the unblocking pusher 12 comes into contact with the surface of the screen plate 8, it is subjected to the tension spring in the limiting component 15, which keeps the unblocking pusher 12 in contact with the surface of the screen plate 8. At the same time, by adjusting the connecting arm 14, the rotating core 13 moves downward and restricts the feed between the outer cylinder 7 and the rotating core 13 from flowing towards the conveying auger 16, ensuring that the feed at the bottom of the rotating core 13 will not flow to the side of the conveying auger 16.

[0047] When the unblocking pusher 12 rotates to the "C"-shaped notch of the screen plate 8, the forward-rotating disengagement inclined section 121 acts as the front of the movement. Simultaneously, when the unblocking pusher 12 moves downward under the action of the tension spring, it pulls one end of the connecting arm 14 downward, while the other end of the connecting arm 14 pulls the rotating core 13 upward. The rotating core 13 moves upward relative to the outer cylinder 7, causing the bottom of the rotating core 13 to move away from the support, allowing the feed at the bottom of the rotating core 13 to flow into the side of the conveying auger 16. As the screen plate 8 continues to rotate, when the disengagement inclined section 121 on the unblocking pusher 12 passes one end of the screen plate 8, the inclined surface of the disengagement inclined section 121 abuts against the end of the screen plate 8, forming a wedge-shaped sliding structure. Utilizing the inclined surface of the disengagement inclined section 121, the unblocking pusher 12 moves upward along the end of the screen plate 8 until the unblocking pusher 12 abuts against the surface of the screen plate 8 again and performs scraping work. As the unblocking pusher 12 reaches the surface of the screen plate 8, it pushes the connecting arm 14 and causes the rotating core 13 to again prevent the feed at its bottom from flowing to the side of the conveying auger 16. This method of periodically feeding feed to the side of the conveying auger 16 allows the heat carried by the hot airflow to process the feed more thoroughly. Furthermore, the shortened distance between the rotating core 13 and the support ensures that a large amount of hot airflow is transported along the conveying auger 16, preventing the problem of heat dispersion due to uneven heat flow. This cyclical operation ensures that the feed inside the outer cylinder 7 is thoroughly cooked and sterilized.

[0048] Finally, when it is necessary to discharge the feed from the outer cylinder 7, the control system causes the drive assembly 3 to rotate in the opposite direction at a low speed. At this time, the conveying auger 16 conveys the feed downwards. At the same time, the gear ring frame on the planetary gear reduction assembly 10 drives the unblocking push block 12 to rotate synchronously in the opposite direction, and the reset inclined part 122 serves as the front of the movement. When the unblocking push block 12 enters the "C"-shaped notch of the screen plate 8, it is subjected to the tension spring in the limiting assembly 15, causing the unblocking push block 12 to enter the notch of the screen plate 8. The unblocking push block 12 pulls the rotating core 13 upwards through the connecting arm 14. The rotating core 13 no longer restricts the flow of the feed at the bottom. After being conveyed by the conveying auger 16, the feed flows downwards into the discharge seat 202 and is finally discharged to the outside.

[0049] During this process, when the reset inclined part 122 passes the end of the screen plate 8, although it will cause the unblocking push block 12 to tend to move upward again, this cannot prevent the rotating core 13 from cutting off the flow of feed at the bottom. When the stop straight part 123 reaches the end of the screen plate 8, since the stop straight part 123 is a plane, it will restrict the movement of the unblocking push block 12 when it reaches the end of the screen plate 8, thereby increasing the movement resistance of the gear ring frame of the planetary gear reduction assembly 10. When the resistance is greater than the limiting force between the central wheel of the planetary gear reduction assembly 10 and the upper limit groove 110 of the feed pipe 11, it forces the elastic limiting component 18 to disengage from the limiting groove 110 and wait to move into the next limiting groove 110 as the feed pipe 11 continues to rotate. During this process, due to the tension spring in the limiting component 15, the unblocking pusher 12 always tends to move downwards. When the power of the central wheel between the feed pipe 11 and the planetary gear reduction assembly 10 is briefly cut off, the unblocking pusher 12, under the action of the tension spring, tends to further enter the notch of the screen plate 8. As a result, when the unblocking pusher 12 moves downwards, the rotating core 13 moves upwards. When the limiting groove 110 engages with the elastic limiting component 18 again, the rotational resistance of the planetary gear reduction assembly 10 increases again. Then, the gear ring frame, through the limiting component 15, causes the reset inclined part 122 on the unblocking pusher 12 to move along the end of the screen plate 8 until the stop straight part 123 abuts against the end of the screen plate 8 again. This process is repeated to ensure that the unblocking push block 12 has a certain range of periodic up-and-down movement during its reverse rotation. When this movement acts on the rotating core 13, the up-and-down movement of the rotating core 13 causes the feed particles to break the arched structure formed between the feed particles as they are discharged outward, thus preventing the feed particles from piling up and causing problems with normal unloading.
