Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of manure treatment, and in particular to an air-drying room and an air-drying system. Background Art

[0002] While livestock and poultry manure is a waste product, it can also be valuable fertilizer. With proper treatment, it can be transformed into valuable resources. For example, chicken manure from poultry farms contains large amounts of protein and bacteria. If not promptly treated, it can become stinky, polluting the environment, and can also breed bacteria, harming the health of the chickens.

[0003] Common methods for treating manure and sewage include composting, bedding reuse, and biogas power generation. These rely on anaerobic or aerobic fermentation to render manure and sewage harmless. However, the fermentation process can easily produce a large amount of odor, polluting the environment and affecting the living experience.

[0004] In addition, manure can be dried by drying it in the sun. However, drying manure in the sun is easily affected by the environment and its quality is unstable. Summary of the Invention

[0005] In view of the above problems, the embodiments of the present application provide an air-drying room and an air-drying system that can efficiently air-dry feces and sewage.

[0006] According to a first aspect of an embodiment of the present application, a drying room is provided, comprising a drying chamber and a drying unit. A material inlet is provided on a first side of the drying chamber, a material outlet is provided on a second side of the drying chamber, the first side and the second side of the drying chamber being opposite, and the drying chamber is used to store materials. The drying unit protrudes from a third side of the drying chamber, absorbs gas from the material inlet and / or the drying chamber, heats it into hot air, and blows the hot air into the drying chamber to dry the materials.

[0007] In some embodiments, the position of the inlet is higher than the position of the outlet.

[0008] In some embodiments, there are at least two drying units, and the two drying units are located on the third side and the fourth side of the drying chamber respectively along the first direction; the first direction is the direction from the first side of the drying chamber to the second side of the drying chamber, or the direction from the second side of the drying chamber to the first side of the drying chamber.

[0009] In some embodiments, two air-drying units are staggered along the first direction.

[0010] In some embodiments, the air drying unit is provided with a guide plate, and an air duct is formed between the guide plate and the upper plate and outer plate of the air drying unit. The gas from the feed inlet is sucked into the air drying unit along the air duct for heating.

[0011] In some embodiments, the guide plate is in an inverted L-shape or an arc shape with its opening facing the air-drying chamber.

[0012] In some embodiments, the air drying unit includes a heating device, and the air outlet of the heating device is not higher than the lower end of the guide plate; the air outlet of the heating device exceeds the side of the guide plate facing the air drying chamber, or the air outlet of the heating device is flush with the side of the guide plate facing the air drying chamber.

[0013] In some embodiments, the air-drying unit further includes a dehumidification device, and a dehumidification port of the dehumidification device is located outside the air-drying unit.

[0014] According to a second aspect of an embodiment of the present application, an air-drying system is provided, comprising a material spreading device and an air-drying room as described in any one of the first aspects; the material spreading device is located in the air-drying chamber of the air-drying room.

[0015] In some embodiments, an axial flow fan is provided between the air drying unit and the air drying chamber, the wind direction of the axial flow fan is from the air drying unit toward the air drying chamber, and the axial flow fan is located below the paving device.

[0016] The air-drying room and air-drying system provided in the embodiments of the present application establish a fully enclosed and sealed structure. The material is fed in from the feed port and discharged from the discharge port. The material is air-dried in the closed air-drying room to prevent odor from overflowing and polluting the environment. During the air-drying process, the air-drying unit absorbs the air in the air-drying room and heats it and blows it toward the air-drying room. The hot air blown out increases the air flow on the surface of the material. The hot air flow takes away moisture and accelerates the drying of the material. During the process, the air-drying unit absorbs the gas from the air-drying room and the feed port, heats it and blows it out, and then absorbs it again, heats it, and blows it out again, thereby realizing the recycling of the hot air. This not only saves the energy consumption required by the air-drying unit to heat the gas to the preset temperature, but also ensures that the temperature in the air-drying room is always high temperature. The material is in a closed and high-temperature air-drying room throughout the process, accompanied by a high-speed hot air flow, so the feces can be dried efficiently and effectively.

Those skilled in the art will understand the specific meanings of the above terms in this application.

[0043] The treatment of livestock and poultry manure has always been a focal issue for the animal husbandry and environmental protection industries. Direct disposal not only pollutes the environment but also depletes the available resources contained within. For example, chickens have a short digestive tract, so nutrients in feed cannot be fully absorbed and must be excreted in the manure. Chicken manure, high in organic matter, crude protein, nitrogen, phosphorus, and potassium, is a high-quality natural fertilizer. By harmlessly treating chicken manure, it can be returned to the fields for crop growth.

[0044] Besides aerobic and anaerobic fermentation, manure can also be treated harmlessly by drying it in the sun, which can be sold as fertilizer or used directly. However, drying manure in the sun has significant drawbacks: the drying time is unstable, and the odor easily evaporates into the surrounding area, affecting the living environment.

[0045] Therefore, the embodiment of the present application provides an air-drying room that can efficiently air-dry feces and sewage.

[0046] It can be understood that the air-drying room provided in the embodiment of the present application is illustrated using livestock and poultry manure as an example, and does not limit the usage scenarios of the air-drying room. The air-drying room provided in the embodiment of the present application can also dry various fresh fruits and vegetables and other objects with moisture.

[0047] Figure 1 It is an axonometric schematic diagram of the air-drying room 4 provided in an embodiment of the present application. Figure 2 This is a schematic diagram of a top view of the air drying room provided in the embodiment of the present application. Figure 1 and Figure 2As shown, the air-drying room 4 provided in the embodiment of the present application includes an air-drying chamber 41 and an air-drying unit 42. A material inlet 4100 is provided on the first side 410 of the air-drying chamber, and a material outlet 4110 is provided on the second side 411 of the air-drying chamber. The first side 410 and the second side 411 of the air-drying chamber are opposite to each other, and the air-drying chamber 41 is used to place the material 01. The air-drying unit 42 protrudes from the third side 412 of the air-drying chamber. The air-drying unit 42 absorbs gas from the material inlet 4100 and / or the air-drying chamber 41, heats it into hot air, and blows the hot air into the air-drying chamber 41 to air-dry the material 01.

[0048] Specifically, the air-drying room 4 is built on the ground 02, and the top plate (not shown) and multiple side plates of the air-drying room 4 form a sealed structure with the ground 02. Material 01 is fed into the air-drying room 41 through the inlet 4100 of the air-drying room 41. As the material 01 moves from the inlet 4100 to the outlet 4110, the air-drying unit 42 blows air on it, gradually drying the material 01 during the movement. The air-dried material 01 is then discharged from the outlet 4110 for subsequent packaging or transportation. The air-drying unit 42 absorbs and heats the surrounding air, and then blows the heated air into the air-drying room 41 through the air outlet, drying the material 01 in the air-drying room 41. At the same time, the high temperature can also kill harmful substances in the chicken manure.

[0049] Optionally, the gas absorbed by the air-drying unit 42 may come from the air-drying chamber 41 .

[0050] Figure 3 It is a schematic diagram of the cross-sectional structure of the air-drying room 4 provided in an embodiment of the present application. As shown in the figure, the air-drying unit 42 absorbs the gas from the air-drying room 41, and after being heated by the heating device 5, blows it into the air-drying room 41 to air-dry the material. In the process of air-drying the material 01 in the air-drying room 4, the interior of the air-drying room 41 is filled with hot air blown out by the air-drying unit 42. The hot air blows through the material 01, taking away the moisture of the material 01, and at the same time, the temperature of the hot air itself drops. At the same time, the air-drying unit 42 has been absorbing the hot air in the air-drying room 41, including the hot air whose temperature drops after drying the material 01, and then blows it into the air-drying room 41 after heating it. Thus, an internal circulation of hot air is formed between the air-drying room 41 and the air-drying unit 42, recycling the heat of the hot air in the air-drying room 41, reducing the energy consumption required for heating the gas, and air-drying the material 01 efficiently and energy-savingly.

[0051] Optionally, the gas absorbed by the air-drying unit 42 may come from the feed inlet 4100 .

[0052] like Figure 3As shown, the air in the drying chamber 41 absorbed by the air-drying unit 42 near the feed inlet 4100 can also come from the feed inlet 4100. After being heated by the air-drying unit 42, it is blown into the air-drying chamber 41 to air-dry the material. Specifically, the material 01 itself has a temperature, which causes the air surrounding the material 01 to also have a temperature. When the material 01 enters the air-drying chamber 41 from the feed inlet 4100, it brings in warm air around the material 01. The air-drying unit 42 absorbs this warm air, heats it to a preset temperature, and then blows it into the air-drying chamber 41. This can reduce the energy consumption of the air-drying unit 42, and air-dry the material 01 efficiently and energy-efficiently.

[0053] For example, if material 01 is livestock and poultry manure, the manure itself ferments, generating heat and causing the air around it to reach a higher temperature. For example, if material 01 is chicken manure, the manure ferments and generates heat during storage, reaching a temperature of approximately 20°C. This heat is then heated by air-drying unit 42 to approximately 60°C, reducing the energy required to heat the air to the specified temperature and conserving energy.

[0054] Optionally, the gas absorbed by the air-drying unit 42 may be a mixed gas from the air-drying chamber 41 and the feed inlet 4100 .

[0055] For example, the air intake of the air-drying unit 42 can be rectangular or oval, with the air intake facing the air-drying chamber 41. Therefore, the air intake of the air-drying unit 42 on the side of the air intake close to the inlet 4100 draws in warm air from the material 01, while the air intake on the side away from the inlet 4100 draws in hot air from the air-drying chamber 41 that has cooled down after air-drying the material 01. Furthermore, since air is fluid, the warm air from the material 01 and the hot air from the air-drying chamber 41 may mix, and the mixed air may be drawn into and heated by the air-drying unit 42.

[0056] The air-drying room 4 provided in the embodiment of the present application is a fully enclosed and sealed structure. The material 01 is fed in from the feed port 4100 and discharged from the discharge port 4110. The material 01 is air-dried in the enclosed air-drying room 4 to prevent the odor from overflowing and polluting the environment. During the air-drying process, the air-drying unit 42 absorbs the air in the air-drying room 4 and heats it and blows it toward the air-drying chamber 41. The hot air blown out increases the air flow on the surface of the material 01. The hot air flow takes away moisture and accelerates the air-drying of the material 01. During the process, the air-drying unit 42 absorbs the gas from the air-drying chamber 41 and the feed port 4100, heats it and blows it out, and then absorbs it again, heats it, and blows it out again, thereby realizing the recycling of the hot air. This not only saves the energy consumption required by the air-drying unit 42 to heat the gas to the preset temperature, but also ensures that the temperature in the air-drying chamber 41 is always high temperature. The material 01 is in the enclosed and high-temperature air-drying chamber 41 throughout the process, accompanied by a high-speed hot air flow, so that the feces can be dried efficiently and effectively.

[0057] In some embodiments, the position of the inlet 4100 is higher than the position of the outlet 4110 .

[0058] Specifically, the air-drying chamber 4 is of a certain height. An inlet 4100 is located above the first side 410 of the air-drying chamber. Materials are fed into the air-drying chamber 41 via a conveyor belt. An outlet 4110 is located below the second side 411 of the air-drying chamber. This outlet 4110 can be connected to an external packaging device for packaging. Material 01 can remain stationary in the air-drying chamber 41 or be slowly moved within the chamber, being air-dried during its movement from the inlet 4100 to the outlet 4110.

[0059] For example, Figure 1 As shown, fresh chicken manure is transported into the drying chamber 41 from the feed port 4100 located above the first side 410 of the drying chamber. A multi-layer conveying paving board 20 can be provided in the drying chamber 41. The chicken manure is spread flat on the paving board 20 and is transported from the upper layer to the lower layer at regular intervals until it is dried into dry chicken manure at the bottom layer and then sent out of the discharge port 4110, completing the drying process from fresh chicken manure to dry chicken manure.

[0060] It is understood that the air-drying room 4 is a closed building with a certain building height. The air-drying room 4 is provided with an inlet 4100 and an outlet 4110. The inlet 4100 of the air-drying room 41 is higher than the outlet 4110. The height difference can extend the movement path of the material 01 in the smaller air-drying room 41, thereby increasing the air-drying time of the material 01 in the air-drying room 41, reducing the floor space of the air-drying room 41, and further reducing the number of corresponding air-drying units 42 set on both sides of the air-drying room 41. While achieving the purpose of effectively drying the material 01, it also greatly reduces the occupation of equipment resources and land resources.

[0061] In some embodiments, there are at least two drying units 42, and the two drying units 42 are located on the third side 412 and the fourth side 413 of the drying chamber respectively along the first direction 03. The first direction 03 is the direction from the first side 410 of the drying chamber to the second side 411 of the drying chamber, or the direction from the second side 411 of the drying chamber to the first side 410 of the drying chamber.

[0062] like Figure 1As shown, the first direction 03 can also be described as the direction from the feed inlet 4100 to the discharge outlet 4110, parallel to the wall of the drying chamber 41. Sequentially refers to the ordering of the drying units 42 based on the third side 412 and the fourth side 413 of the drying chamber. For example, starting from the feed inlet 4100, the first drying unit 42 on the third side 412 of the drying chamber is drying unit 421, the first drying unit 42 on the fourth side 413 of the drying chamber is drying unit 422, the second drying unit 42 on the third side 412 of the drying chamber is drying unit 423, the second drying unit 42 on the fourth side 413 of the drying chamber is drying unit 424, and so on.

[0063] The two consecutive drying units 42 are respectively located at the third side 412 and the fourth side 413 of the drying chamber, so the air outlet directions of the two consecutive drying units 42 are opposite.

[0064] In some embodiments, two drying units 42 can be arranged correspondingly along the first direction 03. When the drying unit 42 is working, the hot air blown out by the drying unit 42 is blown from both sides of the drying chamber 41 to the center, ensuring that there is sufficient hot air in the drying chamber 41.

[0065] However, in the actual design, since the air drying unit 42 is constantly replenishing heat and the chicken manure itself has a certain amount of heat, after analyzing the energy consumption and air drying effect, as shown in the following example: Figure 2 As shown, in some embodiments, two drying units 42 are designed to be staggered along the first direction 03. On the one hand, the staggered arrangement can reduce the number of drying units 42 required in the drying room 4, reducing the capital investment, operating costs, and maintenance costs of the drying equipment. On the other hand, the staggered drying units 42 continuously blow hot air into the drying room 41, absorb hot air from the closed drying room 41, and then blow it out again after heating. The hot air continuously circulates in the drying room 4, and is only slightly consumed when passing through the material 01. Therefore, the staggered drying units 42 are sufficient to dry the material 01.

[0066] Staggered distribution means that in a first direction 03, two consecutive drying units 42 do not overlap in a second direction perpendicular to the first direction 03. For example, as shown in the figure, in drying unit a, drying unit b, drying unit c, drying unit d, etc., no two drying units 42 overlap in the second direction. The distance between the side panels of two consecutive drying units 42 approaching each other in the second direction is zero, thereby ensuring that the two staggered drying units 42 cover every section of material 01 in the drying chamber 41 when blowing air.

[0067] like Figure 2As shown, in some embodiments, the air drying unit 42 is provided with a guide plate 420, and an air duct is formed between the guide plate 420 and the upper plate 421 and outer plate 422 of the air drying unit. The gas from the feed port 4100 is sucked into the air drying unit 42 along the air duct for heating.

[0068] Specifically, the air intake and air outlet of the air drying unit 42 are located at different positions. The air intake of the air drying unit 42 is aligned with the height of the feed inlet 4100, thereby absorbing heat from the material 01 entering the air drying chamber 41 from the feed inlet 4100. By utilizing the air duct, the air drying unit 42 can concentrate the absorbed heat for processing, preventing gas diffusion from affecting processing efficiency.

[0069] In some embodiments, the air drying unit 42 further includes a heating device 5, which is connected to the guide plate 420, dividing the air drying unit 42 into two spaces: an air intake space and an air outlet space. The air intake space includes an air duct formed between the guide plate 420 and the air drying unit 42, through which the hot air from the air drying chamber 41 and / or the inlet 4100 passes, is absorbed by the heating device 5, and is then blown out from the air outlet located in the air outlet space after being absorbed by the heating device 5. The air outlet of the heating device 5 is not higher than the lower end 4201 of the guide plate, and the air outlet of the heating device 5 exceeds the side of the guide plate 420 facing the air drying chamber 41, or the air outlet of the heating device 5 is flush with the side of the guide plate 420 facing the air drying chamber 41, so as to ensure that the hot air is not blocked by the guide plate 420, and is blown from the heating device 5 to the air outlet space, and then blown to the multi-layer paving board 20 in the air drying chamber 41 through a plurality of axial flow fans arranged at the junction of the air outlet space and the air drying chamber 41.

[0070] In some embodiments, the guide plate 420 is in an inverted L-shape or an arc shape with its opening facing the drying chamber 41 .

[0071] Specifically, Figure 4 This is a structural schematic diagram of the inverted L-shaped guide plate provided in an embodiment of the present application. Figure 5 This is a structural diagram of the arc-shaped guide plate provided in the embodiment of the present application. Figure 4 As shown, the guide plate 420 can be an inverted L-shaped plate, which is easy to process. Figure 5 As shown, the guide plate 420 may also be arc-shaped. The arc-shaped plate reduces the wind resistance encountered by the gas when passing through, and is more efficient.

[0072] In some embodiments, the air-drying unit 42 further includes a dehumidification device, and a dehumidification port of the dehumidification device is located outside the air-drying unit 42 .

[0073] It is understood that when the material 01 is dried by hot air, moisture will be generated, and the dehumidification device is used to discharge the moisture out of the air drying room 4. The dehumidification device can be provided with a dehumidification pipe, which extends from the air drying unit 42, and the tail end of the dehumidification pipe, i.e., the dehumidification port, is located outside the air drying unit 42.

[0074] Optionally, the heating device 5 and the dehumidification device can be an integrated device, such as an air energy device, which can have both heating and dehumidification functions.

[0075] By setting up a dehumidification device, moisture can be discharged from the air-drying room 4 while the material 01 is being air-dried, keeping the air-drying room 4 always in a high-temperature, dry environment, providing a good environmental foundation for the air-drying material 01 and improving the air-drying efficiency of the material 01.

[0076] like Figure 1 and Figure 2 As shown, the embodiment of the present application further provides an air-drying system 1, comprising a spreading device 2 and an air-drying room 4 in any of the above embodiments.

[0077] Through the internal heat circulation in the air-drying room 4, the temperature in the air-drying chamber 41 can always be maintained at a high temperature. The paving device 2 is placed in the air-drying chamber 41 to ensure that the material 01 is dried by the high-temperature gas in the air-drying chamber 41 and the hot air blown out by the air-drying unit 42. Drying and air-drying are carried out simultaneously to ensure efficient drying of the manure.

[0078] For example, Figure 4 and Figure 5 As shown, the paving device 2 may include a multi-layer paving board 20. The material 01 is evenly spread on the multi-layer paving board 20, and the multi-layer paving board 20 can transfer the material 01 between the upper and lower layers through a transmission structure. During the air-drying process, the material 01 falls from the upper layer to the lower layer in sequence until it is completely air-dried at the bottom layer.

[0079] In some embodiments, an axial flow fan is provided between the air drying unit 42 and the air drying chamber 41 , and the wind direction of the axial flow fan is from the air drying unit 42 toward the air drying chamber 41 . The axial flow fan is located below the paving device 2 .

[0080] Since the paving device 2 has multiple layers of paving boards 20, each layer of paving boards 20 requires hot air to accelerate drying. Compared with setting up a multi-layer heating device 5, by setting up a multi-layer axial flow fan, the hot air discharged from the heating device 5 is dispersed and blown out to the multi-layer paving boards 20, and the multi-layer material 01 can be dried at a lower cost through simple equipment.

[0081] The axial flow fan blows the hot air generated by the drying unit 42 in layers to the bottom of the paving plate 20. There are multiple small holes on the paving plate 20. The accelerated hot air blows through the bottom of the material 01, taking away some moisture. After that, the hot air will rise and enter through the small holes and pass through the side of the material 01 to dry the material 01 again, thereby greatly improving the drying effect of each blowing.

[0082] The air-drying system 1 provided in the embodiment of the present application, by installing a spreading device 2 in a sealed, high-temperature air-drying room 4, ensures that the material 01 is exposed to the high-temperature environment of the air-drying room 41 and that the hot air from the air-drying unit 42 is always directed toward the material 01, thereby ensuring effective air-drying. The high-temperature drying environment of the air-drying room 41 and the high-speed hot air from the air-drying unit 42 accelerate the drying of the material 01 and effectively improve the air-drying efficiency of the manure.

[0083] In summary, the air-drying room 4 and the air-drying system 1 provided in the embodiment of the present application establish a fully enclosed and sealed structure. The material 01 is fed in from the feed port 4100 and discharged from the discharge port 4110. The air-drying of the material 01 is completed in the closed air-drying room 4 to prevent the odor from overflowing and polluting the environment. During the air-drying process, the air-drying unit 42 absorbs the air in the air-drying room 4 and heats it and blows it toward the air-drying chamber 41. The hot air blown out increases the air flow on the surface of the material 01. The hot air flow takes away moisture and accelerates the air-drying of the material 01. During the process, the air-drying unit 42 absorbs the gas from the air-drying chamber 41 and the feed port 4100, heats it and blows it out, and then absorbs it again, heats it, and blows it out again, thereby realizing the recycling of the hot gas. This not only saves the energy consumption required by the air-drying unit 42 to heat the gas to the preset temperature, but also ensures that the temperature in the air-drying chamber 41 is always high temperature. The material 01 is in the enclosed and high-temperature air-drying chamber 41 throughout the process, accompanied by a high-speed hot air flow, so that the feces can be dried efficiently and effectively. Furthermore, placing the material spreading device 2 in the sealed, high-temperature air-drying room 4 ensures that the material 01 is exposed to the high-temperature environment of the air-drying chamber 41 and that the hot air from the air-drying unit 42 is always directed toward the material 01, thereby ensuring effective air-drying. The drying function provided by the high-temperature environment of the air-drying chamber 41 and the high-speed hot air blown out by the air-drying unit 42 work together to accelerate the drying of the material 01 and effectively improve the air-drying efficiency of the manure.
