[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of the anaerobic digestion biogas residue recycling and treatment device for livestock and poultry manure.

[0028] like Figures 1-8 As shown, the present invention provides a livestock and poultry manure anaerobic digestion biogas residue recycling and treatment device, which includes a support 1 and a solid-liquid separation mechanism installed on the upper end of the support 1.

[0029] The solid-liquid separation mechanism includes a housing 2 mounted on the upper end of a support 1. The housing 2 is fixed to the upper end of the support 1 by a fastener. A screw rod 7 is rotatably mounted inside the housing 2. One end of the screw rod 7 passes through the housing 2 and is connected to the output shaft of the drive motor 5. An end sleeve 6 is provided at the discharge port of the housing 2. The other end of the screw rod 7 passes through the housing 2 and is rotatably connected at the discharge port by the end sleeve 6, ensuring smooth rotation while preventing material leakage. When the biogas residue enters the housing 2, the drive motor 5 drives the screw rod 7. As the screw rod 7 rotates, the biogas residue inside the housing 2 is propelled forward by the screw blades.

[0030] To accommodate materials with different viscosities and properties, a circular plate 11 and an adjusting sleeve 12 are provided on the extended part of the screw rod 7. A spring 10 is connected between the circular plate 11 and the adjusting sleeve 12, allowing for a certain degree of elastic adjustment. The circular plate 11 is located near the discharge port of the housing 2, which can apply additional pressure to the discharged material to help further dewater it. The adjusting sleeve 12 is fixed to the screw rod 7 by bolts 13, and the screw rod 7 has multiple sets of threaded holes. The position of the bolts 13 can be adjusted as needed to change the pressure of the spring 10 and optimize the separation effect.

[0031] A filter cartridge 8 is installed inside the housing 2. The filter cartridge 8 is sleeved on the outside of the screw rod 7. A drain port 9 is opened at the bottom of the housing 2. Due to the design of the screw rod 7 and the tight fit between the filter cartridge 8, the liquid component can flow out through the holes of the filter cartridge 8 and be discharged through the drain port 9, while the solid component continues to move forward. When the amount of solid reaches a certain level, it pushes the circular plate 11, causing the circular plate 11 to move away from the discharge port, thereby discharging the material.

[0032] A feed inlet 3 is provided on the upper side of the shell 2, and a backflow outlet 4 is provided on one side of the feed inlet 3. A pipe is connected to the feed inlet 3 for sucking up the biogas residue, and a pipe is connected to the backflow outlet 4. The discharge end of the pipe is placed in the biogas residue tank to prevent too much biogas residue from entering.

[0033] To prevent material from accumulating at the outlet of the shell 2, a vertical plate 14 is provided at one end of the support 1. The vertical plate 14 can prevent material from entering the bottom of the support 1. A through hole 18 is provided near the upper part of the vertical plate 14. Two sets of pushing components are slidably installed in the through hole 18. The pushing components push the material accumulating at the outlet of the solid-liquid separation mechanism.

[0034] The material pushing assembly includes a movable block 20 that slides within the through hole 18. A cylinder 21 is mounted on the movable block 20. The piston end of the cylinder 21 is connected to a push plate 22. When pushing material, the two sets of movable blocks 20 approach each other, causing the two sets of push plates 22 to fit together. At this time, the cylinder 21 pushes the push plate 22 forward to push the accumulated material to the lower side, ensuring smooth material discharge.

[0035] On the other side of the vertical plate 14, a bidirectional lead screw 23 is rotatably provided. The bidirectional lead screw 23 is driven by a motor. The two ends of the bidirectional lead screw 23 are respectively threadedly connected to two sets of moving blocks 20. The movement of the moving blocks 20 can be achieved by rotating the bidirectional lead screw 23. After the push plate 22 pushes the material, the two sets of moving blocks 20 move in opposite directions by rotating the bidirectional lead screw 23 in the opposite direction, thereby moving the two sets of moving blocks 20 away from the material. At this time, the cylinder 21 retracts, and the push plate 22 can move around the material to the side of the receiving groove 19 opened on one side of the through hole 18, and the push plate 22 is stored in the receiving groove 19.

[0036] Furthermore, a top plate 15 is fixedly installed at one end of the bracket 1, and a guide plate 16 is hinged to one side of the top plate 15. A spring 17 is connected to the top of the guide plate 16 and the top of the top plate 15. The guide plate 16 guides the material discharged from the outlet, so that the material maintains a distance from the push plate 22 in the receiving trough 19, and does not affect the use of the push plate 22.

[0037] The end of the vertical plate 14 is located below the guide plate 16. After the guide plate 16 is impacted by the material, it can be reset by the spring 17. The upper end of the vertical plate 14 limits the downward tilt angle of the guide plate 16, so that the guide plate 16 is kept within a certain tilt range.

[0038] The working principle of an anaerobic digestion biogas residue recycling and treatment device for livestock and poultry manure is as follows: solid-liquid separation of biogas residue is achieved through a solid-liquid separation mechanism. The liquid passes through the filter cylinder 8 and is discharged from the drain outlet 9. The solid is pushed by the screw rod 7 and discharged after being dehydrated by the pressure applied by the circular plate 11. In order to prevent the discharge outlet from being blocked, the cylinder 21 drives the push plate 22 to clean up the accumulated material. The guide plate 16 guides the flow of material to avoid interfering with the operation of the push plate 22, ensuring smooth discharge and stable operation of the equipment.
