DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 5 A kitchen waste biohydrolysis reaction device is shown, comprising an outer ring 2 and an inner ring 3 located at the center of the outer ring 2. A bottom plate 41 is connected between the bottoms of the outer ring 2 and the inner ring 3. An annular reaction chamber 1 is formed between the outer ring 2, the inner ring 3, and the bottom plate 41. A material box 4 is provided on the left side of the outer ring 2 and is connected to the reaction chamber 1. A partition 5 is provided in the middle of the material box 4. One end of the partition 5 is connected to the left side wall of the material box 4, and the other end is connected to the outer periphery of the inner ring 3. The partition 5 divides the interior of the material box 4 into a feed chamber 6 and a discharge chamber 7. A feed valve 8 is provided at the connection between the feed chamber 6 and the reaction chamber 1, and a discharge valve 9 is provided at the connection between the discharge chamber 7 and the reaction chamber 1. The feed valve 8 and the discharge valve 9 are arc-shaped. The portion of the partition 5 located within the reaction chamber 1 is provided with a connecting valve 12. When the amount of organic waste is small, the feed valve 8 and the discharge valve 9 are opened, so that the feed chamber 6 and the discharge chamber 7 are connected to the reaction chamber 1 respectively. The communication valve 12 is closed to isolate the interior of the reaction chamber 1. The organic waste, bacterial strains, and enzymes are transported from the feed chamber 6 to the reaction chamber 1. In the reaction chamber 1, the materials are mixed with the bacterial strains and enzymes to complete the biological hydrolysis. The hydrolyzed materials can be discharged through the discharge chamber 7 for subsequent solid-liquid separation, so that the solid and liquid phase materials can be utilized.

[0024] When the amount of organic waste is large, close the discharge valve 9 and the connecting valve 12, open the feed valve 8, and transport the organic waste, bacteria and enzymes from the feed chamber 6 to the reaction chamber 1.

[0025] Then, close feed valve 8 and open connecting valve 12. The organic waste circulates within reaction chamber 1, allowing the material to be thoroughly mixed with the bacteria and enzymes, allowing more time for biohydrolysis and better conversion of the solid phase of the material into a liquid phase. After sufficient decomposition time, connecting valve 12 is closed, and discharge valve 9 is opened, allowing the hydrolyzed material to be discharged through discharge chamber 7.

[0026] A guide plate 10 and a guide plate 2 11 are provided at the end of the partition 5 near the inner ring 3. The ends of the guide plates 10 and 11 near the inner ring 3 are bent away from the center. The curved guide plates 10 and 11 guide the movement of organic waste within the reaction chamber 1, allowing it to enter and exit the reaction chamber 1 more efficiently.

[0027] A rotating shaft 13 is rotatably provided in the reaction chamber 1. The rotating shaft 13 is radially arranged in the reaction chamber 1. A sleeve 14 is provided on the rotating shaft 13, and a flow-pushing plate 15 is installed on the outer periphery of the sleeve 14. There are several rotating shafts 13, and the rotating shafts 13 are evenly distributed in the reaction chamber 1. The rotating shaft 13 drives the flow-pushing plate 15 to rotate through the sleeve 14. The flow-pushing plate 15 can push the organic waste to move in the reaction chamber 1 and can stir the organic waste, bacteria and enzymes, thereby mixing them for effective biodegradation. A support frame 16 is provided on the outer periphery of the outer ring 2. One end of the rotating shaft 13 that passes through the outer ring 2 is rotatably provided in the support frame 16, and the rotating shaft 13 is rotatably supported by the support frame 16.

[0028] The two ends of the rotating shaft 13 are respectively passed through the outer ring 2 and the inner ring 3. A sealing sleeve 21 is provided at the connection between the rotating shaft 13 and the outer ring 2 and the inner ring 3. The sealing sleeve 21 plays a sealing role to prevent material leakage.

[0029] like Figure 2 As shown, the inner ring 3 is connected to a support base 27, on which a transmission bevel gear 28 is rotatably mounted. A drive motor 29 is mounted on one of the support bases 27. The drive motor 29 drives a driving bevel gear 30, which meshes with the transmission bevel gear 28. The end of the rotating shaft 13 passing through the inner ring 3 is connected to a driven bevel gear 25, which meshes with the transmission bevel gear 28. The drive motor 29 rotates the driving bevel gear 30, which in turn rotates the meshed transmission bevel gear 28. The transmission bevel gear 28 then rotates the meshed driven bevel gears 25, causing the rotating shafts 13 to rotate synchronously. The rotating shaft 13 drives the flow-pushing plate 15 on the sleeve 14 to rotate, completing the mixing and pushing.

[0030] Two limit plates 17 are installed on the rotating shaft 13, and the sleeve 14 is located between the two limit plates 17. The position on the outer periphery of the rotating shaft 13 between the two limit plates 17 is connected to the limit bar 18, and a guide groove that cooperates with the limit bar 18 is opened inside the sleeve 14. The cooperation between the limit bar 18 and the guide groove allows the sleeve 14 to move along the axial direction of the rotating shaft 13 while rotating with the rotating shaft 13. An adjustment mechanism is provided on the rotating shaft 13, which can drive the sleeve 14 to move on the rotating shaft 13. The length of the flow-pushing plate 15 cannot be less than the radial length of the reaction chamber 1, which will cause the material near the outer ring 2 and the inner ring 3 to be retained and cannot be effectively pushed. The position of the sleeve 14 on the rotating shaft 13 is changed by the adjustment mechanism, so that the sleeve 14 is offset to the side of the outer ring 2 or the inner ring 3, thereby stirring the material near the inner ring 3 or the inner ring 3 and driving this part of the material to move. The regulating mechanism periodically drives the sleeve 14 to move on the rotating shaft 13, so that the flow-pushing plate 15 is alternately close to the outer ring 2 or the inner ring 3, so as to compensate for the insufficient stirring of the materials near the outer ring 2 and the inner ring 3.

[0031] like Figure 4 、 Figure 5 As shown, a rotation groove 35 is defined within the sleeve 14. The rotation groove 35 communicates with one end of the rotating shaft 13 located within the inner ring 3. A screw 36 is rotatably disposed within the rotation groove 35. A screw motor 26 is mounted on one end of the rotating shaft 13 located within the inner ring 3. The screw motor 26 is fixedly mounted on the rotating shaft 13 and can rotate along with the rotating shaft 13. The screw motor 26 drives the connecting screw 36. A screw nut block 37 is mounted on the screw 36. A guide hole 39 is defined in the rotating shaft 13. The guide hole 39 is arranged along the axial direction of the rotating shaft 13. A connecting rod 38 is connected to the screw nut block 37. The connecting rod 38 passes through the guide hole 39 and is connected to the inner wall of the sleeve 14.

[0032] A stopper 40 is mounted on the connecting rod 38 and abuts against the inner wall of the rotating shaft 13 to ensure a tight seal between the two. As the screw 36 drives the screw nut block 37 and the sleeve 14 to move, the stopper 40 remains covering the guide hole 39, preventing material from entering the rotating trough 35 through the guide hole 39.

[0033] like Figure 1 、 Figure 3As shown, the bottom plate 41 is provided with a mounting slot 24, which is arranged radially along the reaction chamber 1. An aeration tube 19 is mounted within the mounting slot 24, and the aeration tube 19 is provided with a plurality of aeration holes 31. A check valve 32 is installed above the aeration holes 31 to prevent impurities from entering the aeration tube 19 through the aeration holes 31. An aeration pump 22 is located within the inner ring 3, connected to a rotary joint 23. One end of the aeration tube 19 passes through the inner ring 3 and is inserted into the rotary joint 23. The aeration pump 22 intermittently pumps gas into the reaction chamber 1 through the aeration holes 31 in the aeration tube 19 to aerate the reaction chamber 1. This gas agitates the material outside the stirring area of ​​the propeller plate 15, assisting and supplementing the mechanical agitation of the propeller plate 15, thereby mixing the material with the bacteria and enzymes and enhancing the decomposition effect.

[0034] The aeration tube 19 is rotatably connected to the rotary joint 23. The end of the aeration tube 19, distal from the rotary joint 23, passes through the outer ring 2 and is sealed. By rotating the aeration tube 19 through the outer ring 2, the angle of the aeration holes 31 on the aeration tube 19 can be adjusted, allowing aeration into the reaction chamber 1 from different directions. Different initial inclination angles of the airflow generate different vortices, which agitate the material in the reaction chamber 1 in different directions, achieving a better auxiliary stirring effect.

[0035] Garbage may contain impurities such as glass, sand and gravel. These impurities are heavy and will move along the bottom of the reaction chamber 1, thereby colliding with the aeration tube 19 and causing damage to the aeration tube 19. Along the flow direction of the material, a baffle plate 20 is installed on the bottom plate 41 at a position in front of the aeration tube 19. The baffle plate 20 is arranged at an angle, and the height of the baffle plate 20 close to the aeration tube 19 is higher than the height of the end away from the aeration tube 19. One end of the baffle plate 20 extends above the mounting groove 24, so that it can cover most of the aeration tube 19. The setting of the baffle plate 20 allows impurities such as glass, sand and gravel to move along the upper surface of the baffle plate 20, thereby passing over the aeration tube 19 and not causing damage to the aeration tube 19.

[0036] A sieve plate 33 is provided on the baffle plate 20 near the end connected to the bottom plate 41. The sieve plate 33 is perpendicular to the baffle plate 20 and can intercept larger impurities to prevent these impurities from falling on the aeration pipe 19 due to rapid weight loss in the process of passing through the aeration pipe 19, thereby effectively protecting the aeration pipe 19.

[0037] A receiving trough 34 is provided on the bottom plate 41 below the sieve plate 33 to collect impurities trapped by the sieve plate 33. A retaining plate may also be provided on the top of the receiving trough 34. The retaining plate may have a retaining hole with a larger upper opening and a smaller lower opening. The retaining hole is configured to be larger at the top and smaller at the bottom, so that impurities that enter the receiving trough 34 through the retaining hole are less likely to pass through the sieve holes and then leave the receiving trough 34. These impurities will not move on the bottom plate 41, thereby preventing damage to the aeration tubes.

[0038] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
