Description

Technical Field

[0001] This utility model relates to the field of agricultural waste treatment technology, specifically to a chicken manure drying and transport bed. Background Technology

[0002] Chicken farms generate a large amount of chicken manure daily. Fresh chicken manure has a moisture content as high as 60%-80%. Directly piling it up can easily produce malodorous gases such as ammonia and hydrogen sulfide, polluting the air. Leachate may seep into the soil or flow into water bodies, causing nitrate pollution and eutrophication. Drying chicken manure at high temperatures (usually 70-100℃) can inactivate more than 90% of pathogenic microorganisms, reducing biosecurity risks.

[0003] Economic benefits: Dried chicken manure is rich in nitrogen, phosphorus, potassium and trace elements. It can be used directly as organic fertilizer or processed into granular fertilizer to improve soil structure. After drying, it can partially replace feed protein source. It can be used as biogas feedstock or directly burned for power generation to reduce energy costs for farms. It can be used to produce organic-inorganic compound fertilizer or biochar, and may also be used as raw material in some chemical fields.

[0004] Chinese patent document CN217838702U discloses a chicken manure drying bed, including a frame, sprocket devices movably mounted on both ends of the frame, a motor mounted on the sprocket device at one end of the frame, a conveyor chain connected to the sprocket device, several drying bed plates with one end mounted on the conveyor chain, a rotary rake device movably mounted on the frame and located above the sprocket devices, the drying bed plates covering the conveyor chain, the drying bed plates having convex plates and concave plates provided, the convex plates and concave plates being connected by inclined plates, one end of the convex plate having a second edge, one end of the concave plate having a first edge, the second edge between two drying bed plates covering the first edge; the concave plate end is mounted on the conveyor chain by mounting plate and screws.

[0005] Chinese patent document CN221139758U discloses a manure board guiding mechanism, comprising two spaced-apart mounting plates. The guiding component is characterized by having a guiding assembly mounted on one side of each mounting plate facing each other. The guiding assembly includes a fixed part vertically arranged and fixed to the mounting plates, and a horizontally inclined moving part sliding on the mounting plate below the fixed part. The moving part and the mounting plates are elastically connected, and the moving part and the fixed part cooperate to adjust the movement trajectory of the manure board. This prior art allows for the simultaneous drying of upper and lower layers of chicken manure on a single drying line.

[0006] In the aforementioned prior art, the height of chicken manure piled on the air drying bed is determined by the capacity of the drying bed board. The height of the chicken manure is generally 10-30 cm. Hot air first dries the surface of the chicken manure and then dries the inside of the chicken manure. The inside of the chicken manure is not heated evenly, and due to the limitation of the length of the transmission bed board, the inside of the chicken manure is not easy to dry. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a chicken manure drying and transport bed, including a driving sprocket, a driven sprocket, a chain, and a transport bed plate. The characteristic feature is that a heat transfer pipe is provided above the transport bed plate, and multiple sets of heat transfer plates are provided on the heat transfer pipe, with the end of each set of heat transfer plates located close to the transport bed plate.

[0008] Preferably, the heat transfer pipe is hollow inside, for introducing hot air or hot water.

[0009] In order to transfer heat and move within the chicken manure, the heat transfer plate includes a metal connector and a metal blade, the sharp point of which faces the opposite direction of movement of the transport bed.

[0010] To improve heat transfer efficiency and drying uniformity, multiple sets of heat transfer pipes are provided above the transport bed. The heat transfer plates on each set of heat transfer pipes are staggered with those on adjacent heat transfer pipes, which facilitates the creation of more chicken manure trenches and increases the heat transfer area between the heat transfer plates and the hot air.

[0011] For ease of installation, the transport bed is provided with a bracket and baffles on its periphery, and the two ends of the heat transfer pipe are fixed to the baffles on the left and right sides of the transport bed.

[0012] To further improve the drying efficiency of chicken manure, the chicken manure drying and transport bed is a two-layer flip-plate structure, with heat transfer pipes and heat transfer plates installed on both the upper and lower layers.

[0013] Preferably, the transport bed includes multiple sets of flaps, and a connecting pin is provided at every other connection point of the chain. The flaps are sequentially and movably connected to the connecting pins of the chain. A support rail is provided in the middle of the chain, and the flaps move on the support rail. The flaps hang down naturally at both ends of the chain to remove chicken manure.

[0014] In order to break up the hardened chicken manure and mix the chicken manure with inconsistent moisture content evenly, a roller for stirring and breaking up the manure is provided above the transport bed board, and the roller is equipped with a spirally arranged breaking up column.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses heat transfer pipes and heat transfer plates inserted into the chicken manure for heat transfer. At the same time, the heat transfer plates can open multiple grooves in the chicken manure, making the cross-section of the chicken manure wavy, increasing the windward area and the contact area with hot air. Simultaneously, the heat of the hot air can penetrate into the chicken manure along the entire groove, improving ventilation and heating the deeper layers of chicken manure, and further increasing the temperature of the air duct, making the internal heating of the chicken manure more uniform and avoiding repeated drying operations.

[0017] 2. The multi-layered flip-plate structure enhances the drying effect of chicken manure, solves the environmental pollution problem of livestock waste, and creates economic value through resource utilization. It is one of the key technologies for modern agriculture to achieve "planting and breeding cycle" and "dual carbon goals", which can maximize environmental and economic benefits.

[0026] The reference numerals in the accompanying drawings include: driving sprocket 1, driven sprocket 2, chain 3, connection point 301, connecting pin 302, transport bed 4, heat transfer pipe 5, inlet 501, outlet 502, heat transfer plate 6, metal connector 601, metal blade 602, drive structure 7, bracket 8, baffle 9, cloth placing machine 10, flip plate 11, support rail 12, pulley 13, inner guide ring 14, outer guide arc plate 15, roller 17, dispersing column 18. Example 1

[0027] like Figure 1-7 As shown, a chicken manure drying and transport bed includes a driving sprocket 1, a driven sprocket 2, a chain 3, and a transport bed 4. A heat transfer pipe 5 is horizontally arranged above the transport bed 4, and 11 sets of heat transfer plates 6 are provided on the heat transfer pipe 5. The number of heat transfer plates 6 is adapted to the width of the transport bed 4. The end of each set of heat transfer plates 6 is positioned close to the transport bed 4. When 10-30 cm of chicken manure is accumulated on the transport bed 4, the heat transfer plates 6 can be inserted into the chicken manure for heat transfer and drying. The driving sprocket 1 is driven to rotate by a drive structure 7, and the transport bed 4 moves from the driving sprocket 1 towards the driven sprocket 2. Figure 1 The middle section consists of two overlapping chicken manure drying and transport beds.

[0028] The heat transfer pipe 5 is hollow inside, with one end being an inlet 501 for introducing hot air or hot water, and the other end being an outlet 502 for continuous circulating heating.

[0029] The heat transfer plate 6 includes a metal connector 601 and a metal blade 602, with the sharp point of the metal blade 602 pointing in the opposite direction to the movement of the transport bed plate 4.

[0030] Four sets of heat transfer pipes 5 are provided above the transport bed 4. The heat transfer plates 6 on each set of heat transfer pipes 5 are staggered with the heat transfer plates 6 on the adjacent heat transfer pipes 5, which makes it easier to open up more chicken manure ditches and increase the heat transfer area between the heat transfer plates 6 and the hot air.

[0031] The transport bed 4 is surrounded by a support 8 and a baffle 9. The baffle 9 encloses the chicken manure drying transport bed (only part of the baffle 9 is shown in the figure for easy display of the internal structure). The heat transfer pipe 5 is fixed at both ends to the baffle 9 on the left and right sides of the transport bed 4. The inlet 501 and outlet 502 of the heat transfer pipe 5 are exposed outside the baffle 9. The support 8 is equipped with a material spreader 10, which is located close to the drive sprocket 1.

[0032] The chicken manure drying and transport bed is a two-layer flip-plate structure, with heat transfer pipes 5 and heat transfer plates 6 installed on both the upper and lower layers.

[0033] The transport bed 4 includes multiple sets of flip plates 11. A connecting pin 302 is provided at every connection point 301 of the chain 3. The flip plates 11 are rotatably connected to the connecting pins 302 of the chain 3 in sequence. A support rail 12 is provided in the middle of the chain 3. The flip plates 11 move on the support rail 12 through pulleys 13.

[0034] The driving sprocket 1 and the driven sprocket 2 are respectively provided with an inner guide ring 14 and an outer guide arc plate 15. When the pulley 13 of the flip plate 11 encounters the inner guide ring 14 and the outer guide arc plate 15, it will flatten upward and downward to achieve the simultaneous accumulation and drying of chicken manure in both the upper and lower layers. The flip plate 11 hangs down naturally at both ends of the chain 3 to remove chicken manure. The same structure is used in the manure plate guiding mechanism for manure and sewage disclosed in the existing patent document CN221139758U.

[0035] A roller 17 for stirring and dispersing is provided between the transport bed 4 and the discharge port of the cloth feeder 10, and the roller 17 is provided with spirally arranged dispersing columns 18.
