Detailed Implementation

[0022] 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.

[0023] The following is in conjunction with the appendix Figure 1-7 The specific embodiments of the present invention will be described in further detail below.

[0024] In this embodiment, through Figures 1-7 As shown, the present invention includes a tank body 1, a motor 2 fixed to the top of the tank body 1, two first synchronous pulleys 3 rotatably connected to the tank body 1, both first synchronous pulleys 3 being connected by a first synchronous belt 4, one of the first synchronous pulleys 3 being fixed to the output shaft of the motor 2, and a first mating post 5 inserted into the other first synchronous pulley 3, a reciprocating screw 6 fixed to the tank body 1, the first mating post 5 being threadedly connected to the reciprocating screw 6, a stirring post 7 fixed to the lower end of the first mating post 5, and a grinding component fixed to the stirring post 7. A sieve plate 8 is fixed inside the tank body 1. A mixing component is installed inside the tank body 1. The mixing component is fixed on the stirring column 7. A second mating column 10 is fixed at the bottom of the stirring column 7. The second mating column 10 is inserted into the first mating cylinder 11. The first mating cylinder 11 is rotatably connected to the tank body 1. An air inlet pipe 12 and an air outlet pipe 13 are connected to the tank body 1. A feed inlet 9 is opened on the tank body 1. Multiple drive components are set inside the tank body 1. The multiple drive components are respectively connected to the grinding component and the mixing component to assist the grinding component and the mixing component in operation.

[0025] The first mating column 5, the second mating column 10, the third mating column 41, and the fourth mating column 42 are all composed of cylinders and cross blocks, and their shapes are completely identical. The second synchronous pulley 31, the first mating cylinder 11, the second mating cylinder 17, and the third mating cylinder 43 are all provided with mating grooves that can mate with the cylinders and cross blocks. When the motor 2 drives the first synchronous pulley 3 and the first synchronous belt 4 to run, it drives the first mating column 5 to rotate. While rotating, the first mating column 5 moves up and down in conjunction with the reciprocating screw 6. When the first mating column 5 drives the stirring column 7, the second mating column 10, the third mating column 41, and the fourth mating column 42 to rotate, it also drives the stirring column 7, the second mating column 10, the third mating column 41, and the fourth mating column 42 to reciprocate up and down. However, it can only drive the first mating cylinder 11, the second mating cylinder 17, and the third mating cylinder 43 to rotate; the first mating cylinder 11, the second mating cylinder 17, and the third mating cylinder 43 will not move up and down.

[0026] The biogas residue is poured in through the feed inlet 9, and then the biogas residue is ground by the grinding component. After that, the ground biogas residue enters the lower part of the tank 1 through the screen plate 8. The air inlet pipe 12 is connected to the external oxygen pipeline to introduce oxygen into the tank 1. Then, the biogas residue is moved by the mixing component, so that the biogas residue and oxygen are fully mixed and the oxygen enrichment process continues. The gas outlet pipe 13 can discharge the mixed gas. After the biogas residue has completed fermentation, it can be taken out.

[0027] The rotation of the stirring column 7 drives the first mating cylinder 11 and the second mating cylinder 17 to rotate, thereby enabling the mixing component and the grinding component to operate in conjunction with the drive component.

[0028] A rotating disc can be installed at the bottom of the tank body 1. The rotating disc is threadedly installed at the bottom of the tank body 1. The upper side wall of the installed rotating disc is flush with the bottom of the inner wall of the tank body 1, and is used for removal after the biogas residue is treated.

[0029] In this embodiment, through Figure 2-3 As shown, the grinding assembly includes a receiving plate 14 fixed to the inner wall of the tank 1, a distributing cone 15 fixed to the stirring column 7 below the receiving plate 14, a plurality of distributing plates 16 fixed to the inner wall of the tank 1 below the distributing cone 15, a screen plate 8 located below the distributing plates 16, a second mating cylinder 17 rotatably connected to the screen plate 8, a third mating column 41 inserted into the second mating cylinder 17 fixed to the stirring column 7, a plurality of crushing rods 19 rotatably connected to the second mating cylinder 17 and a plurality of scrapers 18 fixed thereon, and the plurality of crushing rods 19 are all mounted on a drive assembly;

[0030] When the biogas residue is fed into the tank 1 through the feed inlet 9, it falls onto the receiving tray 14 and then drops from the lower end of the receiving tray 14 onto the distribution cone 15. The distribution cone 15 rotates and moves up and down with the stirring column 7, which can break up and separate the biogas residue that falls onto the distribution cone 15. The biogas residue falls onto the distribution tray 16 and then from the lower end of the distribution tray 16 onto the screen tray 8. The screen tray 8 has small holes for screening the biogas residue. Small-volume biogas residue enters through the small holes and falls to the bottom of the tank 1. Large volumes of biogas residue are located above the screen plate 8. The second cooperating cylinder 17 drives the crushing rod 19 and scraper 18 to move. The crushing rod 19 drives the sprocket 39 to rotate around the central axis of the second cooperating cylinder 17. The sprocket 39 meshes with the gear ring 40 and rotates, thereby driving the crushing rod 19 to rotate and crush the biogas residue. Then the scraper 18 scrapes up the biogas residue adhering to the screen plate 8, continuously crushing the large volumes of biogas residue, thereby reducing the volume of biogas residue and causing it to fall into the bottom of the tank 1 through the small hole.

[0031] In this embodiment, the mixing component includes a fourth mating column 42 fixed to the stirring column 7. A third mating cylinder 43 is inserted into the fourth mating column 42. Two long rods 20 rotating on the stirring column 7 are mounted on the third mating cylinder 43. A set of connecting blocks 21 is rotatably connected to each of the two long rods 20. A bucket 22 is fixed to each of the two sets of connecting blocks 21. A shovel plate 23 is fixed to each of the two buckets 22. There are two connecting blocks 21 in each set. Short rods 24 are fixed to each of the two connecting blocks 21 near the inner wall of the tank 1. The two short rods 24 are both inserted through and fixed to a driving component. Each connecting block 21 has an opening. There are round holes 25, and each round hole 25 is provided with a coil spring 26. One end of each coil spring 26 is fixedly connected to the connecting block 21, and the other end of each coil spring 26 is fixed to the long rod 20. The two short rods 24 are fixed with matching balls 27 at the ends near the tank 1. The two matching balls 27 are slidably connected to the slide 28 opened on the inner wall of the tank 1. A first long cylinder 29 is fixedly connected to the first matching cylinder 11 and a second long cylinder 30 is rotatably connected to it. A first stirring component and a second stirring component are respectively installed on the first long cylinder 29 and the second long cylinder 30. The first long cylinder 29 and the second long cylinder 30 are both installed on a drive component.

[0032] The rotation of the stirring column 7 drives the fourth mating column 42 to rotate, which in turn drives the third mating cylinder 43 to rotate. This, in turn, drives the two long rods 20 to rotate around the axis of the stirring column 7. The long rods 20 drive the connecting block 21, bucket 22, shovel plate 23, short rod 24, and mating ball 27 to rotate. The mating ball 27 slides in contact with the slide rail 28. While moving around the central axis of the third mating cylinder 43, the mating ball 27 undulates along the trajectory of the slide rail 28, thereby driving the bucket 22 to move up and down. The slide 28 is divided into four sections: two symmetrical V-shaped slides 28 and two symmetrical straight slides 28, arranged in the order of V-shaped slide 28, straight slide 28, V-shaped slide 28, and finally straight slide 28. When the ball 27 is on the straight slide 28, it rotates around the axis of the stirring column 7 and on the same horizontal plane. When the ball 27 is on the V-shaped slide 28, it rotates up and down around the axis of the stirring column 7. When the ball 27 drives the short rod 24 and the circular gear 39 to move to the straight slide... When 28 is engaged, the sprocket 39 meshes with the gear ring 40, thereby driving the short rod 24 and the connecting block 21 to rotate. The toothed blocks on the gear ring 40, which meshes with the sprocket 39 on the short rod 24, are divided into multiple groups. There is a toothless area between every two groups of toothed blocks. Each group of toothed blocks can rotate 60° with the sprocket 39. Then the sprocket 39 reaches the toothless area and disengages from the gear ring 40. At this time, the coil spring 26 drives the connecting block 21, the bucket 22, the short rod 24, and the sprocket 39 to rotate and reset, so that the bucket... When the bucket 22 rotates around the third mating cylinder 43 on the straight slide 28, it can continuously shake. After rotating 60°, it returns to its original position, allowing the biogas residue in the bucket 22 to fall from the hole opened on the bucket 22. During the process of the biogas residue falling from the bucket 22, the contact area with oxygen can be increased, thereby accelerating fermentation. When the bucket 22 moves to the lowest point on the V-shaped slide 28, it can be filled with biogas residue. Biogas residue is continuously scattered on the straight slide 28, and the cycle can accelerate the fermentation speed of biogas residue.

[0033] In this embodiment, the first stirring assembly includes a plurality of second synchronous pulleys 31 rotatably connected to the first long cylinder 29. The second synchronous pulley 31 closest to the inner wall of the tank 1 is fixed to the first helical gear 33. The first helical gear 33 is meshed with a second helical gear 34, which is fixed to the drive assembly. The first long cylinder 29 is rotatably connected to the drive assembly. The plurality of second synchronous pulleys 31 are all connected by a second synchronous belt 32. A plurality of first rotating rollers 35 are rotatably connected to the first long cylinder 29. The plurality of first rotating rollers 35 are respectively fixed to the plurality of second synchronous pulleys 31. The lower end of each first rotating roller 35 is fixed with a turntable 36, and a plurality of stirring blades 37 are fixed on each turntable 36.

[0034] A stop plate is fixed inside the first long cylinder 29. The stop plate is attached to the outer wall of the second synchronous belt 32 to prevent the second synchronous belt 32 from jumping when the second synchronous pulley 31 is running, which would cause it to disengage from the second synchronous pulley 31.

[0035] When the first long cylinder 29 rotates with the first mating cylinder 11, it can drive the spur gear 39 to rotate around the central axis of the first mating cylinder 11. The spur gear 39 meshes with the gear ring 40 and can rotate on its own. The rotation of the spur gear 39 drives the second helical gear 34 to rotate. The second helical gear 34 can drive the first helical gear 33 to rotate, thereby driving the second synchronous pulley 31 and the second synchronous belt 32 to rotate, so that all the second synchronous pulleys 31 rotate. The rotation of the second synchronous pulleys 31 drives the first rotating roller 35 to rotate. The first rotating roller 35 drives the turntable 36 and the stirring blade 37 to rotate, thereby mixing the biogas residue.

[0036] In this embodiment, the second stirring assembly includes multiple stirring plates 38 fixed on the second long cylinder 30. The second long cylinder 30 is fixed on the drive assembly. When the second long cylinder 30 rotates around the central axis of the first cooperating cylinder 11, it can rotate with the circular gear 39, thereby driving the stirring plates 38 to rotate, so that the biogas residue on the upper and lower sides of the second long cylinder 30 is mixed. Together with the first stirring assembly, it mixes the biogas residue below the first long cylinder 29, which can make the biogas residue more thoroughly mixed. When the biogas residue is continuously stirred and mixed, it is scooped up and dropped by the bucket 22, which can improve the fermentation speed of the biogas residue and make faster recycling and processing of the biogas residue. The fermented biogas residue can be well used for agricultural fertilizer, animal feed and environmental remediation, etc., and can be better utilized.

[0037] In this embodiment, the drive assembly includes a gear ring 40 fixed to the inner wall of the tank 1, and a spur gear 39 meshes on the gear ring 40.

[0038] In this embodiment, the multiple crushing rods 19 are respectively fixed to multiple spur gears 39 on a drive assembly connected to the grinding assembly, the two short rods 24 are respectively fixed to two spur gears 39 on another drive assembly connected to the mixing assembly, the first long cylinder 29 is rotatably connected to a spur gear 39 on one of the drive assemblies connected to the mixing assembly, the second long cylinder 30 is fixedly connected to a spur gear 39 on one of the drive assemblies connected to the mixing assembly, and the second helical gear 34 is fixed to a spur gear 39 on a drive assembly connected to the mixing assembly. The first long cylinder 29, the second long cylinder 30, and the second helical gear 34 are all disposed on the same drive assembly.

[0039] There are three sets of drive components. The first set of drive components is connected to the short rod 24, the second set of drive components is connected to the first long cylinder 29 and the second long cylinder 30, and the third set of drive components is connected to the crushing rod 19.
