Description

TECHNICAL FIELD

[0001] The present application relates to the field of feed processing, in particular to an efficient grinding and sterilization integrated feed processing system and method. BACKGROUND

[0002] In the field of feed processing, the grinding fineness and sterilization effect of raw materials directly affect the quality of feed and animal absorption efficiency, which is a key link to ensure the healthy development of the breeding industry. At present, the feed processing equipment on the market mostly adopts a "grinding and sterilization" step-by-step operation mode, that is, the raw materials are first crushed by a grinding device, and then the crushed raw materials are transferred to a sterilization device (such as a high-temperature steam sterilization machine, a chemical sterilization device, etc.) for sterilization. This separate processing mode has obvious limitations.

[0003] Firstly, the step-by-step operation leads to a long processing flow, which not only increases the time cost of raw material transfer, but also requires additional investment in multiple devices, resulting in high equipment purchase and maintenance costs. At the same time, the operation of multiple devices consumes more energy, which does not meet the current industry demand for energy saving and consumption reduction. Secondly, traditional grinding devices are mostly single-stage grinding structures, which only crush the raw materials once through the impact of the crushing teeth, making it difficult to ensure uniform particle size of the raw materials. Moreover, when the moisture content of the raw materials is high, they are prone to sticking to the inner wall of the grinding chamber and the crushing components, which not only reduces the grinding efficiency, but also requires frequent shutdown for cleaning, affecting the continuity of production.

DETAILED DESCRIPTION

[0017] The technical solutions in 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. Example

[0018] Please see the appendix Figure 1 -Appendix Figure 6 The present invention provides a highly efficient integrated feed processing system for grinding and sterilization, such as... Figure 1 As shown, it includes a grinding chamber 1, which is the core space for the first grinding operation of the feed raw materials to be processed. Its internal structural design directly determines the efficiency and effect of the initial grinding. A feed pipe 2 is fixedly installed at the bottom of the grinding chamber 1 and is connected to the interior of the grinding chamber 1. The feed pipe 2 is not only a channel for receiving the raw materials after initial grinding in the grinding chamber 1, but also allows for secondary grinding and high-temperature sterilization of the raw materials. The design of the two being connected ensures that the raw materials after initial grinding in the grinding chamber 1 can smoothly enter the feed pipe 2, realizing the continuous connection of the processing flow.

[0019] A feed pipe 3 is fixedly installed on one side of the crushing chamber 1 and is connected to the interior of the crushing chamber 1. The feed pipe 3 is the initial channel for the feed raw materials to be processed to enter the entire system. The raw materials will undergo pretreatment in the feed pipe 3 before entering the crushing chamber 1. The design of its connection with the interior of the crushing chamber 1 can ensure that the pretreated raw materials can smoothly enter the crushing chamber 1 for crushing. An annular screen grating plate 5 is fixedly installed inside the crushing chamber 1. The main function of the annular screen grating plate 5 is to screen the particle size of the raw materials after the initial crushing by the crushing tooth plate 7. Only the raw materials that meet the preset particle size requirements can fall into the feed pipe 2 through the annular screen grating plate 5. The raw materials that do not meet the requirements will remain in the crushing chamber 1 and continue to be crushed by the crushing tooth plate 7, thereby ensuring that the particle size of the raw materials after the initial crushing is uniform, laying the foundation for the subsequent secondary grinding operation.

[0020] The inner middle part of the crushing chamber 1 is movably mounted with a crushing main shaft 6, which is a core component for power transmission in the crushing chamber 1. One end of the crushing main shaft 6 is connected with an external power structure, and the other end extends to one side close to the feeding pipe 3 and is connected with an extension shaft 8. Through its own rotation, the crushing main shaft 6 can provide power for the crushing operation of the crushing tooth plate 7 and the rotation of the extension shaft 8. The movable mounting mode enables flexible rotation, ensures efficient power transmission, and the crushing main shaft 6 is uniformly fixed with a plurality of sets of crushing tooth plates 7 on the outer diameter. The crushing tooth plates 7 rotate at high speed under the driving of the crushing main shaft 6, and can cooperate with the inner wall of the crushing chamber 1 and the annular sieve grate 5 through impact, shearing and other ways to preliminarily crush the raw materials entering the crushing chamber 1. The plurality of sets of evenly distributed crushing tooth plates 7 can cover most of the space in the crushing chamber 1, so that the raw materials can be fully impacted and sheared during the crushing process, improving the efficiency and uniformity of the preliminary crushing.

[0021] The extension shaft 8 is a key structure for connecting the crushing main shaft 6 and the internal components of the feeding pipe 3. It rotates synchronously with the crushing main shaft 6, can drive the compression auger 9 on its outer diameter to rotate, and can drive the cylinder 11 and the material conveying auger 12 to rotate through the cooperation of the spline 14 and the key groove 13, realizing the conveying and pretreatment of the raw materials in the feeding pipe 3. The design of the extension shaft 8 extending to the inside of the feeding pipe 3 ensures that the extension shaft 8 can accurately cooperate with the components in the feeding pipe 3, stably transmits power, and the compression auger 9 is fixedly installed on the outer diameter of the extension shaft 8 close to the crushing chamber 1. The compression auger 9 rotates under the driving of the extension shaft 8, and its main function is to receive the accumulated raw materials pushed from the cylinder 11, extrude the raw materials through rotation, extrude the water contained in the raw materials, and continuously convey the extruded and dehydrated raw materials to the crushing chamber 1, so as to remove water interference for subsequent crushing operation, and avoid the raw materials from sticking to the inner wall of the crushing chamber 1 or the crushing tooth plate 7 due to too much water content.

[0022] The inner side of the feeding pipe 3 away from the crushing chamber 1 is movably provided with a barrel 11, which is a core component for realizing the feeding and reciprocating pushing of the raw materials in the feeding pipe 3. The barrel 11 can rotate under the driving of the extension shaft 8, thereby driving the feeding auger 12 to feed the raw materials. The barrel 11 can also make transverse reciprocating linear motion in the feeding pipe 3 under the cooperation of the round head pin 16 and the bidirectional helical groove 15, so as to push the raw materials accumulated between the feeding auger 12 and the compression auger 9 into the compression auger 9. The movable mounting mode ensures that the rotation and reciprocating motion of the barrel 11 can be smoothly performed without jamming. The end of the barrel 11 close to the crushing chamber 1 is fixedly provided with the feeding auger 12. The feeding auger 12 rotates synchronously with the barrel 11. The feeding auger 12 feeds the raw materials away from the crushing chamber 1 in the feeding pipe 3 to the crushing chamber 1. During the feeding process, because there is a certain distance between the feeding auger 12 and the compression auger 9, the raw materials will gradually accumulate between the two, thereby preparing for the subsequent compression and water removal. The fixed mounting at the end of the barrel 11 ensures that the feeding auger 12 can stably and synchronously rotate with the barrel 11, thereby improving the stability of the raw material feeding.

[0023] In the embodiment, the middle part of the top end of the feeding pipe 3 is fixedly provided with a hopper 4. The hopper 4 is a component for feeding the raw materials to be processed into the feeding pipe 3. The operator can directly pour the raw materials to be processed into the hopper 4. The raw materials will enter the inside of the feeding pipe 3 under the action of their own gravity. The fixed position of the hopper 4 at the middle part of the top end of the feeding pipe 3 can ensure that the raw materials are uniformly dropped into the feeding pipe 3, thereby avoiding the accumulation of the raw materials at the inlet of the feeding pipe 3 and ensuring the smoothness of feeding. The bottom end of the feeding pipe 3 is fixedly provided with a draining mesh plate 10 close to the compression auger 9. The main function of the draining mesh plate 10 is to guide the water discharged when the raw materials are extruded by the compression auger 9 out of the feeding pipe 3, thereby avoiding the accumulation of water in the feeding pipe 3 and affecting the pretreatment effect of the raw materials. The installation position close to the compression auger 9 can timely receive and discharge the extruded water, thereby ensuring that the water content of the raw materials is greatly reduced before entering the crushing chamber 1 and further avoiding the sticking problem during subsequent crushing.

[0024] Further, the inside of the barrel 11 is provided with key grooves 13 on both sides. The key grooves 13 are key structures for realizing the power transmission between the barrel 11 and the extension shaft 8. The key grooves 13 can accommodate the splines 14 on the extension shaft 8. Through the limiting cooperation of the splines 14 and the key grooves 13, the extension shaft 8 can drive the barrel 11 to rotate synchronously when the extension shaft 8 rotates. Meanwhile, the length design of the key grooves 13 can provide sufficient space for the transverse reciprocating linear motion of the barrel 11. The design of the key grooves 13 on both sides can ensure the stability and balance of the power transmission of the extension shaft 8 to the barrel 11, thereby avoiding the deviation of the barrel 11 during rotation.

[0025] The outer diameter of the extension shaft 8 is fixedly provided with a spline 14 near the key groove 13, and the outer end of the spline 14 is movably arranged in the corresponding side key groove 13. The spline 14 is fixed on the extension shaft 8, and the outer end of the spline 14 is movably embedded in the key groove 13. This matching mode not only realizes the power transmission between the extension shaft 8 and the cylinder 11, so that the extension shaft 8 can stably drive the cylinder 11 to rotate, but also ensures that the spline 14 can freely move in the key groove 13 in the axial direction, without limiting the transverse reciprocating linear motion of the cylinder 11, so that the cylinder 11 can smoothly complete the reciprocating pushing action of the raw materials while rotating, and provides stable power for the pretreatment of the raw materials.

[0026] A bidirectional spiral groove 15 is formed in the inner wall of the feeding pipe 3 near the cylinder 11. The bidirectional spiral groove 15 is a track structure for guiding the transverse reciprocating linear motion of the cylinder 11. It is composed of two spiral grooves connected end to end but with opposite spiral directions. When the round head pin 16 on the cylinder 11 moves in the groove, it will change the direction of motion along the spiral groove, thereby driving the cylinder 11 to reciprocate in the feeding pipe 3. The opening position near the cylinder 11 ensures that the round head pin 16 can be accurately embedded in the groove and move smoothly, providing stable guidance for the reciprocating motion of the cylinder 11.

[0027] A round head pin 16 is fixedly installed on one side of the top end of the cylinder 11, and the end of the round head pin 16 is movably arranged in the bidirectional spiral groove 15. The round head pin 16 is a core component connecting the cylinder 11 and the bidirectional spiral groove 15. When the cylinder 11 rotates, the end will move along the groove in the bidirectional spiral groove 15. When the round head pin 16 moves to the tail of one of the spiral grooves, it will immediately enter the head of the other spiral groove and change the direction of motion, thereby driving the cylinder 11 to move transversely and reciprocally in the feeding pipe 3. The movable arrangement ensures that the round head pin 16 does not jam when moving in the groove, ensuring the stability and regularity of the reciprocating motion of the cylinder 11, and thereby realizing the orderly accumulation and pushing of the raw materials.

[0028] Further, a fixed support 17 is fixedly installed inside the discharging pipe 2. The fixed support 17 is a fixed structure supporting the rotating shaft 18. It is fixed inside the discharging pipe 2 and can provide a stable installation basis for the rotating shaft 18, avoiding the displacement or shaking of the rotating shaft 18 during rotation, thereby ensuring the normal operation of the flinger 19 and the grinding wheel 20, and improving the stability of the grinding structure inside the discharging pipe 2, providing reliable support for subsequent secondary grinding and sterilization operations.

[0029] The middle part of the fixed support 17 is movably mounted with a rotating shaft 18, which is a power core component for realizing secondary grinding and sterilization of raw materials in the blanking pipe 2. The rotating shaft 18 can rotate flexibly under the support of the fixed support 17, and can drive a plurality of spin plates 19 on the outer diameter to rotate synchronously when rotating. At the same time, the spin plates 19 can also drive the grinding wheels 20 to move in the annular grinding groove 21, thereby providing sufficient power for secondary crushing and high-temperature sterilization of raw materials. The movable mounting design ensures that the rotating shaft 18 can efficiently transmit power to drive the subsequent components to work stably.

[0030] A plurality of spin plates 19 are uniformly fixed and mounted on the outer diameter of the rotating shaft 18. The spin plates 19 will rotate at high speed under the drive of the rotating shaft 18. The main function of the spin plates 19 is to use the centrifugal force generated by rotation to throw the primary crushed raw materials falling into the blanking pipe 2 and on the surface thereof into the annular grinding groove 21. The plurality of uniformly distributed spin plates 19 can ensure that the raw materials are evenly thrown and sent, so as to avoid the accumulation of raw materials in a certain area, improve the efficiency and uniformity of secondary grinding, and ensure that the raw materials can smoothly enter the annular grinding groove 21.

[0031] A plurality of grinding wheels 20 are movably mounted on the inner side end outside of the connected spin plates 19. The grinding wheels 20 are movably mounted on the inner side end outside of the connected spin plates 19. When the spin plates 19 rotate, the grinding wheels 20 will roll in the annular grinding groove 21, and crush and grind the raw materials in the groove by cooperating with the inner wall of the annular grinding groove 21. The plurality of uniformly mounted grinding wheels 20 can ensure that the raw materials can be fully crushed at each position in the annular grinding groove 21, thereby further improving the crushing fineness of the raw materials. The movable mounting design enables the grinding wheels 20 to roll flexibly and tightly fit with the annular grinding groove 21, thereby ensuring the crushing effect.

[0032] The inner wall of the blanking pipe 2 is provided with an annular grinding groove 21 near each group of grinding wheels 20. The annular grinding groove 21 is a key place for secondary crushing and high-temperature sterilization of raw materials. The opening position of the annular grinding groove 21 corresponds to the grinding wheels 20 one by one. When the grinding wheels 20 roll in the groove, they can crush and grind the raw materials by cooperating with the groove wall, and can also generate high temperature on the inner wall of the annular grinding groove 21 due to high-speed friction. The high temperature directly acts on the raw materials in the groove, so that the secondary crushing and high-temperature sterilization are performed synchronously. The design that each group of grinding wheels 20 corresponds to an annular grinding groove 21 ensures that each grinding wheel 20 can fully play a role, thereby improving the overall processing efficiency and effect.

[0033] Further, the bottom end of the rotating shaft 18 extends below the fixed support 17 and is fixedly installed with a driven bevel gear 22. The driven bevel gear 22 is fixed at the bottom end of the rotating shaft 18. Its main function is to receive the power transmitted by the driving bevel gear 24. When the driving bevel gear 24 rotates, it will drive the driven bevel gear 22 to rotate synchronously, thereby driving the rotating shaft 18 to rotate, realizing the transmission of power from the transmission shaft 23 to the rotating shaft 18. The fixed installation mode ensures that the driven bevel gear 22 can rotate synchronously with the rotating shaft 18, and the power transmission has no loss. The design of extending below the fixed support 17 facilitates the precise meshing connection with the driving bevel gear 24.

[0034] The transmission shaft 23 is movably installed on the inner bottom side of the feeding pipe 2. The transmission shaft 23 is an intermediate component for transmitting external power to the grinding structure inside the feeding pipe 2. It is movably installed on the inner bottom side of the feeding pipe 2, with the outer side connected to the second driven pulley 29 and the inner side connected to the driving bevel gear 24. When the second driven pulley 29 rotates, it will drive the transmission shaft 23 to rotate, thereby driving the driving bevel gear 24 to rotate, providing power for the rotation of the rotating shaft 18. The movable installation design ensures that the transmission shaft 23 can rotate flexibly and efficiently transmit power.

[0035] The driving bevel gear 24 is fixedly installed on the inner side of the transmission shaft 23 and is meshed and connected with the inner side of the driven bevel gear 22. The driving bevel gear 24 is fixed on the inner side of the transmission shaft 23 and transmits the rotating power of the transmission shaft 23 to the driven bevel gear 22 through meshing connection, thereby driving the rotating shaft 18 to rotate. This meshing connection mode can realize vertical transmission of power, perfectly adapt to the installation direction of the transmission shaft 23 and the rotating shaft 18, ensure efficient and stable power transmission, and the fixed installation mode ensures that the driving bevel gear 24 can rotate synchronously with the transmission shaft 23, avoiding slipping phenomenon during power transmission.

[0036] Further, the feeding pipe 2 is fixedly installed with a motor fixing frame 25 on one side. The motor fixing frame 25 is a supporting structure for fixing the three-phase asynchronous motor 26. It is fixed on one side of the feeding pipe 2 and can provide a stable installation platform for the three-phase asynchronous motor 26, avoiding the three-phase asynchronous motor 26 from shaking or shifting during work, thereby ensuring that the driving pulley 27 can rotate stably and providing reliable power for the entire system. The fixed installation mode improves the stability and safety of the three-phase asynchronous motor 26 during work.

[0037] The top of the motor fixing frame 25 is fixedly provided with a three-phase asynchronous motor 26, which is a power source of the whole high-efficiency crushing and sterilization integrated feed processing system. The three-phase asynchronous motor 26 is fixed on the top of the motor fixing frame 25 and can drive the driving pulley 27 to rotate when working, thereby driving the first driven pulley 28 and the second driven pulley 29 to rotate through the transmission belt 30, providing power for the rotation of the crushing main shaft 6 and the transmission shaft 23, and finally realizing a series of operations such as conveying, pretreatment, crushing, grinding and sterilization of raw materials. The fixed installation mode ensures that the motor can stably output power and guarantee the normal operation of the whole system.

[0038] The driving end of the three-phase asynchronous motor 26 is fixedly provided with the driving pulley 27. The driving pulley 27 is fixed on the driving end of the three-phase asynchronous motor 26 and rotates synchronously with the driving end of the motor. The driving pulley 27 transmits power of the three-phase asynchronous motor 26 to the first driven pulley 28 and the second driven pulley 29 through the transmission belt 30, and is a starting component of power transmission of the whole system. The fixed installation mode ensures that the driving pulley 27 can be tightly connected with the driving end of the motor, the power transmission is efficient, and relative sliding does not occur.

[0039] The first driven pulley 28 is fixedly installed on the end of the crushing main shaft 6 extending to the outside of the crushing chamber 1. The first driven pulley 28 is fixed on the end of the crushing main shaft 6 extending to the outside of the crushing chamber 1. The first driven pulley 28 receives power transmitted by the driving pulley 27 through the transmission belt 30 and drives the crushing main shaft 6 to rotate synchronously when rotating, thereby providing power for the crushing operation of the crushing tooth plate 7 and the rotation of the extension shaft 8. The fixed installation mode ensures stable power transmission between the first driven pulley 28 and the crushing main shaft 6. The design of extending to the outside of the crushing chamber 1 facilitates the connection of the first driven pulley 28 with the transmission belt 30, and realizes effective reception of power.

[0040] The second driven pulley 29 is fixedly installed on the outside end of the transmission shaft 23 extending to the outside of the discharging pipe 2. The second driven pulley 29 is fixed on the end of the transmission shaft 23 extending to the outside of the discharging pipe 2. The second driven pulley 29 receives power transmitted by the driving pulley 27 through the transmission belt 30 and drives the transmission shaft 23 to rotate synchronously when rotating, thereby driving the rotating shaft 18 to rotate through the driving bevel gear 24 and the driven bevel gear 22, providing power for the secondary grinding and sterilization operation in the discharging pipe 2. The fixed installation mode ensures that the second driven pulley 29 rotates synchronously with the transmission shaft 23, the power transmission is reliable, the design of extending to the outside of the discharging pipe 2 facilitates the connection of the second driven pulley 29 with the transmission belt 30, and realizes stable reception of power.

[0041] The outer diameters of the driving pulley 27, the first driven pulley 28 and the second driven pulley 29 are connected through the transmission belt 30, which is a key component connecting the driving pulley 27, the first driven pulley 28 and the second driven pulley 29, and is wound on the outer diameters of the three pulleys, and can simultaneously transmit the rotating power of the driving pulley 27 to the first driven pulley 28 and the second driven pulley 29, so as to realize the synchronous driving of the crushing main shaft 6 and the transmission shaft 23 by the three-phase asynchronous motor 26, and then make the primary crushing operation in the crushing chamber 1 and the secondary grinding and sterilization operation in the feeding pipe 2 be carried out synchronously. Through the connection mode of the transmission belt 30, not only the structure is simple, but also the maintenance and repair of the equipment are convenient, and meanwhile the high efficiency of power transmission can be ensured.

[0042] Four supporting legs 31 are uniformly fixed and installed on the outer diameter of the feeding pipe 2, and the supporting legs 31 are uniformly fixed on the outer diameter of the feeding pipe 2, which mainly provides stable support for the whole efficient crushing and sterilization integrated feed processing system, so that the system can be stably placed on the ground or working platform.

[0043] The efficient crushing and sterilization integrated feed processing method comprises the following processing steps: Step one: the feed raw material to be crushed is sent into the feeding pipe 3 through the hopper 4, and then the three-phase asynchronous motor 26 is started, and through the transmission of the driving pulley 27, the transmission belt 30 and the first driven pulley 28, the extension shaft 8, the cylinder 11, the conveying auger 12 and the compression auger 9 are driven to rotate, and at the same time, the cylinder 11 will reciprocate in the feeding pipe 3, and after the raw material is accumulated, the compression auger 9 is used for compression, and the water in the raw material is pressed out and then sent into the crushing chamber 1; Step two: the raw material is crushed by the high-speed rotating crushing tooth plate, and then is screened by the annular screening grate 5, and the screened raw material enters the feeding pipe 2; Step three: the raw material falls on the surface of the flinger 19, and the high-speed rotating flinger 19 flings the raw material into the annular grinding groove 21, and the high-speed grinding wheel 20 performs secondary grinding on the raw material, and at the same time, the high-speed friction between the grinding wheel 20 and the annular grinding groove 21 generates high temperature, which can sterilize the raw material at high temperature, and after completion, the raw material falls from the bottom opening of the feeding pipe 2.
