The surface of the air diversion sphere is inclined to an arc surface, which can also prevent the raw materials from remaining on the surface of the diversion sphere, so that the air is evenly in contact with the raw materials, which can greatly reduce the residue of the raw materials and facilitate the cleaning and use of the fermentation cylinder;

[0020] 2. Air and water droplets enter the mixing tube, and the air and water droplets continuously impact the spiral space inside the mixing tube, causing the air and water droplets to continuously roll, and the air and water droplets are evenly mixed through the spiral channel, so that the raw materials, air and water droplets are fully and evenly contacted, which has the advantage of full fermentation;

[0021] 3. The rotating disk rotates rapidly inside the air diversion sphere, and the air diversion sphere throws the air and water droplets into the exhaust pipe. The air and water droplets are discharged from the air diversion sphere through the evenly distributed exhaust pipe, so that the raw materials are fully and evenly in contact with the air and water droplets, and the rotating disk stirs the air and water droplets horizontally to make them evenly mixed again. At the same time, the rotating disk drives the air flow at a high speed, and the exhaust pipe protrudes from the inner wall of the air diversion sphere. The rotation of the water droplets generates centrifugal force. The larger the water droplets, the greater the inertia and centrifugal force. Large particles of water droplets are thrown on the inner wall of the diversion hood and cannot enter the exhaust pipe. Small particles of water droplets are mixed with the air and enter the exhaust pipe and are discharged from the diversion hood, so that the raw materials, air and water droplets are evenly mixed.

A plurality of convex pieces are integrally formed at one end of the water inlet columns 16, and the spacing between the convex pieces is consistent with the size of the notches.

[0034] During specific implementation, water is stored in the water storage tray 15, and the water flows in through the gap at the top of the water inlet column 16. Then the water flows along the multiple fin surfaces of the water inlet column 16. The air flows from top to bottom along the fin surfaces. The air carries away the water on the fin surfaces to form water droplets, and the water can be evenly and slowly input into the airflow.

[0035] Preferably, the mixing tube 25 is spirally wound clockwise on the surface of the rotating tube 23, the top of the mixing tube 25 is integrally formed with a latch portion, the latch portion is inserted into the mixing tube 25 and enters the space inside the mixing tube 25, the bottom of the mixing tube 25 extends into the splitter cover 18, the rotating tube 23, the third bearing 24 and the connecting tube 17 are sequentially sleeved, and the bottom of the rotating rod 21 is truncated cone-shaped;

[0036] During specific implementation, the mixing tube 25 spirals on the surface of the rotating tube 23, and the air and water droplets continuously impact the spiral space inside the mixing tube 25, so that the air and water droplets move quickly in the spiral space, and the air and water droplets continuously rub against the inner wall of the mixing tube 25. The air and water droplets continuously roll in the spiral space, and the air and water droplets are evenly mixed through the spiral channel, so that the raw materials, air and water droplets are fully and evenly contacted.

[0037] Preferably, one end of the exhaust pipe 19 is matched with the surface of the diverter cover 18, and the other end of the exhaust pipe 19 protrudes from the inner wall of the diverter cover 18. The two diverter covers 18 are combined to form a hollow air diverter sphere. The rotating disk 10 is disc-shaped and its center coincides with the center of the air diverter sphere. The other end of the exhaust pipe 19 faces the center of the air diverter sphere. The exhaust pipe 19 is divided into multiple circles and surrounds the air diverter sphere.

[0038] During specific implementation, two diversion hoods 18 form an air diversion sphere placed in the fermentation cylinder 1, and air and water droplets are discharged through the surface of the air diversion sphere. The air diversion sphere can evenly inject air and water droplets into various positions inside the fermentation cylinder 1, and the surface of the air diversion sphere is inclined to an arc surface, which can also prevent raw materials from remaining on the surface of the diversion ball, so that the air is evenly in contact with the raw materials, and the residue of raw materials can be greatly reduced.

[0039] Preferably, the first bearing 8 is located between the rotating shaft 9 and the fermentation cylinder 1, discharge ports are provided on both sides of the fermentation cylinder 1, a pressing block is provided at the bottom of the threaded rod 6, and the pressing block is located directly above the movable plate 4, and the connecting member 3 is a rotating shaft or a hinge;

[0040] During the specific implementation, the threaded rod 6 rotates to move up and down in the threaded barrel 5, and the pressing block at the bottom of the threaded rod 6 abuts against the movable plate 4 to prevent the movable plate 4 from moving on both sides of the fermentation barrel 1, so that the movable plate 4 is closely attached to the surface of the fermentation barrel 1, which is convenient for the discharge of raw materials and the use of the fermentation barrel 1;

[0041] A fermentation process, step 1, remove the cover plate 12, pour the raw material into the feed inlet of the installation cover 2, and then block the feed inlet of the installation cover 2 with the cover plate 12, so that the raw material fills the fermentation cylinder 1;

[0042] In this process, one or more of livestock and poultry manure, urban domestic garbage, crop straw, agricultural and sideline products, and organic waste generated by food processing are first crushed into various basic raw materials, and then the various basic raw materials are stirred and mixed to form the raw materials to be fermented;

[0043] Step 2: Pour water onto the water storage tray 15, and the water flows into the air inlet 13 through the gap of the water inlet column 16. The AC motor 20 drives the rotating rod 21, the support rod 22, the rotating tube 23, the mixing tube 25 and the fan blades 26 to rotate. The fan blades 26 form an airflow to carry the water droplets entering the end of the water column 16, and then the air and the water droplets enter the rotating tube 23, and the air enters the mixing tube 25. The air and the water droplets are evenly mixed in the mixing tube 25 and finally discharged into the inside of the two diverter covers 18;

[0044] In this process, water flows in through the notch at the top of the water inlet column 16, and then the water flows along the surface of the multiple fins of the water inlet column 16. The air flows from top to bottom along the surface of the fins, and the air takes away the water on the surface of the fins to form water droplets, which can evenly and slowly input the water into the air flow. The filter 14 can filter the air to prevent dust from entering the air inlet tube 13.

[0045] Step 3: The servo motor 7 drives the rotating shaft 9 and the rotating disk 10 to rotate at a high speed. The rotating disk 10 throws the internal air and water droplets of the two diverter covers 18 into the exhaust pipe 19. The air and water droplets are evenly discharged from the surfaces of the two diverter covers 18. The air and water droplets are evenly dispersed into the raw materials, so that the raw materials are fully fermented.

[0046] During this process, the rotating disk 10 rotates rapidly inside the air diversion sphere, and the air diversion sphere throws the air and water droplets into the exhaust pipe 19. The air and water droplets are discharged from the air diversion sphere through the evenly distributed exhaust pipes 19, so that the raw materials are fully and evenly in contact with the air and water droplets, and the rotating disk 10 horizontally stirs the air and water droplets to make them evenly mixed again. At the same time, the rotating disk 10 drives the air to flow at a high speed, and cooperates with the inner wall of the air diversion sphere protruding from the exhaust pipe 19. The water droplets rotate to generate centrifugal force. The larger the water droplets, the greater the inertia and centrifugal force. The large particles of water droplets are thrown on the inner wall of the diversion cover 18 and cannot enter the exhaust pipe 19. The small particles of water droplets are mixed with the air and enter the exhaust pipe and are discharged from the diversion cover 18. The small particles of water droplets can be screened out to prevent the raw materials, air and water droplets from being evenly mixed.

[0047] Step 4: Rotate the threaded rod 6 to move it upward in the threaded cylinder 5, then lift the movable plate 4, and then discharge the raw materials from the discharge port on the side of the fermentation cylinder 1;

[0048] In this process, after the raw materials are discharged from the discharge port of the fermentation cylinder 1 , the raw materials remaining on the surface of the diverter hood 18 can be shaken off by vibration, thereby reducing the residual raw materials inside the fermentation cylinder 1 .
