Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example:

[0033] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides an integrated processor for membrane fermentation of straw and coordinated degradation of microplastics, including a fermentation tank 1. A rotating frame 11 is the main place for membrane fermentation of straw and degradation of microplastics. A crushing box 2 is fixedly connected to the top of the fermentation tank 1. The crushing box 2 can crush the materials put in, so that the contact between the materials and the microorganisms is more complete. The outer wall of the crushing box 2 is fixedly connected to a motor 4. The motor 4 serves as a power source to provide power for a crushing roller 5. Two crushing rollers 5 are rotatably connected to the top of the crushing box 2. The two crushing rollers 5 rotate to crush the straw into smaller particles. The two crushing rollers 5 are fixedly connected to the side away from the motor 4 with a circular gear 6. By setting the two circular gears 6, one of the crushing rollers 5 will drive the other crushing roller 5 after rotating. The outer side of one of the circular gears 6 is fixedly connected with a driving pulley 7, which provides a basis for driving other components in the future. The output end of the motor 4 is fixedly connected to the outer wall of one of the crushing rollers 5, so as to transmit the power of the motor 4 to one of the crushing rollers 5, and further rotate the two crushing rollers 5. A distribution component is arranged inside the crushing box 2, and the distribution component is used to respectively send the crushed materials into the fermentation tank 1 to avoid a large amount of materials entering the fermentation tank 1 at the same time, which makes the reaction insufficient. A reciprocating component is arranged on the outer wall of the crushing box 2, and the reciprocating component is the main structure for controlling the action of the powder component. A control component is arranged on the top of the fermentation tank 1, and the control component is used to control the amount of the fermentation promoter entering the fermentation tank 1.

[0034] The distribution assembly includes two rotating shafts 15, and the two rotating shafts 15 are rotatably connected to the outer wall of the crushing box 2. Through the rotatable connection, the two rotating shafts 15 can drive the separation assembly to work by their own rotation. The two rotating shafts 15 are fixedly connected to the opposite side with a fixed plate 17, and the fixed plate 17 is used to rotate with the rotating shaft 15, and then swing. The bottom of the fixed plate 17 is rotatably connected to two connecting rods 18, and the connecting rods 18 are used to connect the second mounting plate 19 and the fixed plate 17, so that the swing of the fixed plate 17 can drive the second mounting plate 19 to move up and down. A second mounting plate 19 is rotatably connected to the bottom of 18, a plurality of connecting columns 20 are fixedly connected to the bottom of the second mounting plate 19, a conveying plate 21 is fixedly connected between the bottoms of the plurality of connecting columns 20, the second mounting plate 19, the connecting columns 20 and the conveying plate 21 form a transport box, when the second mounting plate 19 rises, the crushed material will fall between the second mounting plate 19 and the conveying plate 21, when the second mounting plate 19 descends, the material will be fed into the fermentation tank 1, during this process, the second mounting plate 19 and the conveying plate 21 will both cover the feeding trough 22 to ensure the accuracy of material transportation.

[0035] Please refer to the attached Figure 7 The reciprocating assembly includes a turntable 8, which is rotatably connected to the outer wall of the crushing box 2. The turntable 8 is rotatably connected to the outer wall of the crushing box 2 so that the turntable 8 can rotate freely, thereby realizing the normal operation of the reciprocating assembly. The edge of the outer wall of the turntable 8 is fixedly connected to an eccentric shaft 9, and the rotation of the turntable 8 drives the eccentric shaft 9 to rotate, and the eccentric design makes the rotating frame 11 on the outer wall of the eccentric shaft 9 reciprocate. The eccentric shaft 9 is fixedly connected to a first limit plate 10 on the side away from the turntable 8. The first limit plate 10 is used to limit the rotating frame 11 to ensure that the rotating frame 11 does not separate from the surface of the eccentric shaft 9 during the sliding process. The outer wall of the eccentric shaft 9 is slidably connected to the rotating frame 11, and the rotating frame 11 reciprocates by the rotation of the eccentric shaft 9. The bottom of the rotating frame 11 is fixedly connected to a connecting rod 12, and the connecting rod 12 is used to transmit the reciprocating sliding motion of the rotating frame 11.

[0036] Please refer to the attached Figure 3 and attached Fig. 9 The control component includes a shell 25 and a storage cylinder 23. The shell 25 is fixedly connected to the top of the fermentation tank 1. The shell 25 is used to store the fermentation promoter that needs to be added to the fermentation tank 1. The storage cylinder 23 is fixedly connected to the top of the fermentation tank 1. The storage cylinder 23 is used to protect the items inside it. A pipe 24 is fixedly connected between the storage cylinder 23 and the shell 25. The pipe 24 is used to transport the fermentation promoter. A baffle 26 is slidably connected inside the shell 25. The baffle 26 is used to cover the pipe 24. The baffle 26 slides up and down to achieve the effect of quantitative discharge.

[0037] Please refer to the attached Figure 5 -Attached Figure 7 One of the crushing rollers 5 is fixedly connected to a driving pulley 7 on the outside, and a driven pulley 27 is fixedly connected to the outer wall of the turntable 8. A belt 28 is sleeved between the driving pulley 7 and the driven pulley 27. When the motor 4 drives the crushing roller 5 to rotate, the driving pulley 7 also rotates accordingly. Through the transmission of the belt 28, the driven pulley 27 drives the turntable 8 to rotate, thereby realizing the linkage between the crushing process and the movement of the reciprocating component.

[0038] Please refer to the attached Figure 8 , a fan gear 16 is fixedly connected to the outer wall of one of the rotating shafts 15, a first mounting plate 13 is fixedly connected to the outer wall of the connecting rod 12, a rack plate 14 is fixedly connected to the outer wall of the first mounting plate 13, the rack plate 14 and the fan gear 16 are meshed, and one end of the connecting rod 12 away from the rotating frame 11 is fixedly connected to the top of the baffle 26. When the connecting rod 12 reciprocates up and down driven by the rotating frame 11, the rack plate 14 also moves up and down accordingly. Since the rack plate 14 is meshed with the fan gear 16, the fan gear 16 rotates, thereby driving the rotating shaft 15 to rotate, thereby realizing the linkage between the distribution component and the reciprocating component.

[0039] Please refer to the attached Figure 8 The circumference of the fan gear 16 is equal to the length of the fixed plate 17, and is relative to the diameter of the turntable 8. When the turntable 8 rotates one circle, the fixed plate 17 will also slide a certain length and make the fan gear 16 rotate a certain amount, so that the fixed plate 17 can swing stably under the drive of the fan gear 16.

[0040] Please refer to the attached Figure 4 The two circular gears 6 are meshed with each other to ensure the synchronous reverse rotation of the two crushing rollers 5. A feed port 3 is provided on the top of the crushing box 2 to facilitate the feeding of materials.

[0041] Please refer to the attached Figure 1 -Attached Figure 3 A discharge port 31 is fixedly connected to the bottom of the fermentation tank 1, and a control valve 33 is installed on the outer wall of the discharge port 31. The discharge port 31 is used to discharge the fermentation and degradation products in the fermentation tank 1. The control valve 33 can control the speed and timing of the discharge. An exhaust valve 32 is provided at the bottom of the outer wall of the fermentation tank 1. The exhaust valve 32 is used to discharge the gas generated during the fermentation process.

[0042] Please refer to the attached Figure 6Two guide plates 29 are fixedly connected to the inner wall of the crushing box 2. The guide plates 29 are used to guide the crushed materials and prevent the materials from flying inside the crushing box 2. A plurality of second limit plates 30 are fixedly connected inside the crushing box 2. The second limit plates 30 are used to limit the fixed plate 17. A slope 34 is fixedly connected to the bottom of the crushing box 2. The slope 34 is used to guide the materials at the bottom of the crushing box 2 to ensure that the materials can accurately enter between the second mounting plate 19 and the conveying plate 21.

[0043] Please see attached Figure 6 Two feeding grooves 22 are provided on the inner bottom wall of the crushing box 2, and the outer wall of the conveying plate 21 is slidably connected to the inside of the feeding groove 22. The feeding groove 22 provides a guide and limit function for the up and down reciprocating motion of the conveying plate 21, ensuring that the conveying plate 21 can stably push the material into the fermentation tank 1 during the movement.

[0044] Working principle: When straw and microplastics need to be degraded at the same time, the straw and plastic are transported to the crushing box 2 by a conveyor. Then, the motor 4 is powered on and started. When the motor 4 is powered on, the electrical energy is converted into mechanical energy, which further drives one of the crushing rollers 5 to rotate. When the crushing roller 5 rotates, it drives the circular gear 6 to rotate. Since the two circular gears 6 are in a meshing state, the rotation of one circular gear 6 will drive the other circular gear 6 to rotate, thereby causing the two crushing rollers 5 to rotate relative to each other, thereby crushing the straw and plastic.

[0045] When the circular gear 6 rotates, the driving pulley 7 is also driven to rotate. A belt 28 is provided on the outer side of the driving pulley 7 and the driven pulley 27. Therefore, the rotation of the driving pulley 7 drives the driven pulley 27 to rotate through the belt 28. When the driven pulley 27 rotates, the turntable 8 is driven to rotate. When the turntable 8 rotates, the eccentric shaft 9 is driven to rotate, and the rotating frame 11 on the outer wall of the eccentric shaft 9 is further caused to slide up and down. The up and down sliding of the rotating frame 11 drives the connecting rod 12 to slide up and down. When the connecting rod 12 slides up and down, it drives the first mounting plate 13 to slide up and down.

[0046] When the first mounting plate 13 slides up and down, it will drive the rack plate 14 to slide. The sliding of the rack plate 14 will drive the fan gear 16 to rotate through the engagement with the fan gear 16. Because the circumference of the fan gear 16 is relative to the diameter of the rack plate 14, and the fan gear 16 is fan-shaped, the rotation of the fan gear 16 will drive the rotating shaft 15 to rotate periodically. When the rotating shaft 15 rotates back and forth, it will drive the fixed plate 17 to rotate back and forth. When the fixed plate 17 rotates back and forth, it will drive the two connecting rods 18 at the bottom thereof to slide, and further enable the second mounting plate 19 to drive the connecting column 20 and the conveying plate 21 to slide inside the feeding trough 22, thereby conveying the crushed straw and plastic to the inside of the fermentation tank 1.

[0047] When the connecting rod 12 slides, the baffle 26 will also slide up and down. When the baffle 26 slides upward, the baffle 26 will not block the pipe 24 at the bottom of the storage cylinder 23, so that the fermentation promoter inside the storage cylinder 23 can enter the fermentation tank 1, thereby improving the fermentation efficiency of straw and plastic. When the baffle 26 slides downward, the pipe 24 will be blocked, so that the fermentation promoter will not enter the fermentation tank 1, thereby achieving a quantitative effect and ensuring sufficient reaction.

[0048] During the fermentation process, the gas generated by the fermentation will be discharged through the exhaust valve 32. At the same time, when the fermentation is completed, the objects inside the fermentation tank 1 can be discharged through the discharge port 31 by opening the control valve 33.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
