Abstract
Description
Technical Field
[0001] This utility model relates to the field of livestock excrement treatment technology, and in particular to a biogas residue extraction device. Background Technology
[0002] According to a survey by the National Dairy Cattle Industry Technology System, in 2024, dairy farms with more than 500 head of cattle accounted for 85% of the total number of dairy cattle in my country, making them the main body of dairy farming. There were more than 100 dairy farms (or groups) with more than 3,000 head of cattle, 83 farms with more than 10,000 head of cattle, and the total number of dairy cattle reached 3.05 million, producing a huge amount of manure every day.
[0003] A dairy farm with 10,000 cows typically produces around 1,000 tons of manure per day. After processing, the manure can be mixed with other raw materials for composting and fermentation before being used as bedding. However, because manure processing requires solid-liquid separation, existing separation equipment still contains a large amount of cow manure in the separated liquid, resulting in unsatisfactory separation effects and low bedding production.

[0034] This invention provides a biogas residue extraction device that improves separation efficiency.
[0035] The following is combined Figures 1-5 The technical solution provided by this utility model will be described in more detail.
[0036] This utility model provides a biogas residue extraction device, comprising:
[0037] Outer cylinder 1, wherein a liquid outlet 8 is provided on the outer cylinder 1;
[0038] Inner cylinder 2, the inner cylinder 2 is provided with a slag outlet 9, the slag outlet 9 is provided in correspondence with the liquid outlet 8, the slag outlet 9 is provided with an opening and closing door, the inner cylinder 2 is rotatably disposed inside the outer cylinder 1, and the inner cylinder 2 is provided with a plurality of separation holes 17 on the cylinder wall.
[0039] The drive mechanism 4 is connected to the inner cylinder 2 in a transmission manner, and is used to drive the inner cylinder 2 to rotate;
[0040] The biogas slurry collection mechanism 5 is located below the slurry outlet 8;
[0041] A reciprocating moving mechanism 6 is connected to the biogas slurry collection mechanism 5 to drive the biogas slurry collection mechanism 5 to reciprocate between the collection position and the avoidance position;

The residue outlet 9 is correspondingly provided with the liquid outlet 8. The residue outlet 9 is provided with an opening and closing door, which can open or close the residue outlet 9. When the liquid outlet 8 and the residue outlet 9 are both at the top and the opening and closing door is in the open state, sewage can be injected into the inner cylinder 2. When the liquid outlet 8 and the residue outlet 9 are both at the bottom and the opening and closing door is in the open state, the residue outlet 9 can discharge downwards. Biogas residue; when the opening and closing door is in the closed state, the driving mechanism 4 is connected to the inner cylinder 2, and the driving mechanism 4 can drive the inner cylinder 2 to rotate, so that the manure water in the inner cylinder 2 is quickly separated into biogas slurry. The biogas slurry is discharged into the outer cylinder 1 through the separation hole 17, and can be discharged from the liquid outlet 8 to the biogas slurry collection mechanism 5 below, thereby realizing biogas slurry collection; after the biogas slurry is collected, the reciprocating moving mechanism 6 drives the biogas slurry collection mechanism 5 to move to the avoidance position, and opens the opening and closing door, so that the biogas residue in the inner cylinder 2 can be discharged to the biogas residue collection mechanism 7 below, completing the biogas residue extraction, greatly improving the separation efficiency and separation effect, greatly increasing the amount of biogas residue extracted, and increasing the amount of bedding material for cattle.
[0044] Understandably, the reciprocating moving mechanism 6 drives the biogas slurry collection mechanism 5 to move to the collection position, with the biogas slurry collection mechanism 5 facing the outlet 8. At this time, the biogas slurry collection mechanism 5 is used to collect biogas slurry. After the biogas slurry is collected, the biogas slurry collection mechanism 5 can move to the avoidance position under the drive of the reciprocating moving mechanism 6, thereby facilitating the collection of biogas residue.
[0045] In some embodiments of this utility model, the biogas residue collection mechanism 7 includes a collection frame 10, an extrusion plate 11, and an extrusion drive assembly 12. The extrusion plate 11 is slidably disposed in the collection frame 10, and the extrusion drive assembly 12 is connected to the extrusion plate 11 to drive the extrusion plate 11 to reciprocate.
[0046] In some embodiments of the present invention described above, the biogas residue collection mechanism 7 includes a collection frame 10, a pressing plate 11, and a pressing drive assembly 12. The pressing drive assembly 12 drives the pressing plate 11 to move within the collection frame 10, thereby pressing the biogas residue within the collection frame 10 through the pressing plate 11, further completing the extraction of biogas residue and ensuring that the liquid content in the biogas residue is minimized.
[0047] In some specific embodiments of this utility model, the extrusion plate 11 is disposed inside the collection frame 10, and the extrusion plate 11 divides the collection frame 10 into a biogas residue extrusion zone 13 and a liquid buffer zone 14. The biogas residue extrusion zone 13 and the liquid buffer zone 14 are connected by a flow hole 15 disposed on the extrusion plate 11.
[0048] In some specific embodiments of the present invention described above, the extrusion plate 11 divides the collection frame 10 into a biogas residue extrusion zone 13 and a liquid buffer zone 14. The extrusion plate 11 completes the extrusion in the biogas residue extrusion zone 13, and the extruded liquid flows into the liquid buffer zone 14 through the flow hole 15, thereby further completing the solid-liquid separation of the biogas residue.
[0049] In some embodiments of this utility model, the biogas residue compression zone 13 is higher than the liquid buffer zone 14.
[0050] In some of the embodiments of this utility model described above, the height of the biogas residue compression zone 13 is higher than that of the liquid buffer zone 14. By utilizing the characteristic of liquid flowing to lower levels, it is easier for liquid to flow into the liquid buffer zone 14.
[0051] In some embodiments of this utility model, the reciprocating moving mechanism 6 includes a reciprocating drive component, a reciprocating moving track, and a reciprocating moving slider. The reciprocating moving track and the reciprocating moving slider cooperate with each other. The biogas slurry collection mechanism 5 is disposed on the reciprocating moving slider, and the reciprocating drive component is connected to the reciprocating moving slider.
[0052] In some of the embodiments of this utility model described above, the reciprocating slider is driven to move back and forth on the reciprocating guide rail by the reciprocating drive component, thereby realizing the mechanized control of the movement of the biogas slurry collection mechanism 5.
[0053] Specifically, the reciprocating drive assembly is a reciprocating motion assembly in the prior art, such as a cylinder, a hydraulic cylinder, or a motor screw assembly, which will not be described in detail here.
[0054] In some embodiments of this utility model, the driving mechanism 4 includes a driving motor and a coupling. The two ends of the inner cylinder 2 are mounted on a fixed base, and the two ends of the inner cylinder 2 are rotatably connected to the fixed base. The driving motor is connected to the inner cylinder 2 through the coupling.
[0055] In some embodiments of this utility model described above, the drive mechanism 4 includes a motor and a coupling, and drives the inner cylinder 2 to rotate via the motor. The outer cylinder 1 is rotatably connected to the inner cylinder 2, enabling the outer cylinder 1 to rotate when needed. If necessary, a limiting structure can be provided between the outer cylinder 1 and the fixed base to limit the rotation of the outer cylinder 1.
[0056] In some embodiments of this utility model, a limiting seat is provided on the fixed base, a limiting block is provided on the outer cylinder 1, and the limiting seat is located on the rotation path of the limiting block.
[0057] In some embodiments of this utility model, the outer cylinder 1 is rotatably connected to the inner cylinder 2 via a bearing.
[0058] In some embodiments of this utility model, the outer cylinder 1 is further provided with a discharge port 16, which is located on the side away from the liquid outlet 8.
[0059] In some embodiments of this utility model described above, by providing a discharge port 16, when the liquid outlet 8 and the slag outlet 9 are both located at the top and the opening and closing door is in the open state, sewage can be injected into the inner cylinder 2. The sewage flows into the outer cylinder 1 through the separation hole 17 and is finally discharged into the liquid collection mechanism through the discharge port 16. This avoids the liquid volume in the outer cylinder 1 being too large and concentrated when sewage is injected, which would affect the rotation of the outer cylinder 1.
[0060] It is understandable that an openable sealing door can also be provided on the outlet 16.
[0061] In some embodiments of this invention, a pumping mechanism is also provided on the biogas slurry collection mechanism 5. This pumping mechanism allows the biogas slurry collected by the collection mechanism 5 to be pumped back into the inner cylinder 2 for secondary separation. The finally separated biogas slurry is discharged into an oxidation pond. The extracted biogas residue is used to produce electric feed for cattle bedding.
