Description

Technical Field

[0001] This application relates to the field of livestock breeding technology, and in particular to a dry-wet separation pigsty using ex-situ fermentation. Background Technology

[0002] In pig farming, pig manure is a major source of environmental pollution. If left untreated, it will pollute the environment. With the continuous development of waste treatment technology, pig manure is generally treated through collection and fermentation, and the fermented manure is a good organic fertilizer. Current pig manure fermentation technology typically involves collecting pig manure and fermenting it uniformly. However, since pig manure contains not only excrement but also urine and wastewater from cleaning pigsties, this mixture of wet and dry excrement produces a large amount of foul odor during fermentation, hindering the process. Existing technology uses specialized dry-wet separation equipment for separation. However, for the manure produced daily in pigsties, firstly, it is inconvenient to have dedicated collection and transportation equipment for separation; secondly, the volume produced by a single pigsty is small and the frequency is high, making equipment operation inconvenient, especially for non-large-scale pig farmers. Utility Model Content

[0003] To address or partially address the problems existing in related technologies, this application provides a dry-wet separation pigsty using off-site fermentation, which facilitates the dry-wet separation of manure and reduces the large amount of odor generated by mixed fermentation.

[0004] This application discloses a dry and wet separation pig house using ex-situ fermentation, including a pen surrounded by four walls. Inside one end of the pen, there are a feed trough and a water trough, and outside the other side, there are a dry fermentation tank and a wet fermentation tank. A partition wall is set on the side away from the feeding trough. A manure collection trough is set at the rear end of the partition wall. A manure outlet is set on the partition wall to connect to the manure collection trough. The bottom of the manure collection trough is lower than the bottom plate of the pen. The external transverse direction of the manure collection tank has a first discharge port and a second discharge port on the same side. The first discharge port is connected to the liquid inlet and the second discharge port is connected to the dry material inlet. The liquid inlet is located on the wet fermentation tank and the dry material inlet is located on the dry fermentation tank. The middle part of the fecal collection tank has a vertically constructed liquid collection tank with parallel partition walls that connect to the first discharge port; the liquid collection tank is covered with a filter screen cover. The bottom plate of the pen is inclined towards the manure outlet; The bottom of the manure collection trough is divided into two parts by the liquid collection trough. The side closer to the pen is inclined towards the liquid collection trough and also towards the liquid inlet. The side farther from the pen is inclined towards the edge of the manure collection trough and also towards the dry feed inlet.

[0005] Optionally, the bottom plate of the pen at the manure outlet can be made into an arc shape.

[0006] Optionally, the length of the liquid collection trough is two-thirds of the vertical length of the fecal collection trough.

[0007] Optionally, the liquid collection tank is constructed with steps, and a filter screen cover is removably installed on the steps.

[0008] Optionally, a filter plate is installed inside the liquid inlet.

[0009] The technical solution provided in this application may include the following beneficial effects: This device uses a manure collection trough lower than the pigpen to temporarily store manure. The pigpen floor is tilted, and a liquid collection trough is located in the middle of the manure collection trough to collect liquid first. This trough is also tilted at the bottom, allowing for the collection of liquid first, followed by solids, thus achieving dry-wet separation of the manure. The manure is then sorted and sent to appropriate fermentation tanks for fermentation or other treatment, avoiding the generation of large amounts of foul odors from mixing dry and wet excrement during fermentation. Furthermore, this application does not use other equipment to assist in dry-wet separation; it achieves dry-wet separation entirely through the structural design of the pigpen, making it suitable for small-scale farming and avoiding the inconvenience of using equipment.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0017] To address the aforementioned problems, this application provides a dry-wet separation pigsty employing ex-situ fermentation. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2The illustration shows a dry-wet separation pigsty employing in-situ fermentation, comprising a pen enclosed by four walls 1. Inside one end of the wall 1, a feed trough 2 and a water trough 3 are located, while on the other side outside, a dry fermentation tank 5 and a wet fermentation tank 6 are located. The improvement of this application lies in that a partition wall 11 is provided on the side furthest from the feed trough 2, dividing the pigsty into two parts, such as... Figure 1 As shown, the front part is for piglet rearing, and the rear part is for collecting pig manure (separating wet and dry manure). Specifically, it is divided into a manure collection trough 4 by a partition wall 11. A manure outlet 12 is provided on the partition wall 11 to connect to the manure collection trough 4 for convenient manure collection. The bottom of the manure collection trough 4 is lower than the bottom plate of the pigpen for easy manure stacking. To facilitate wet and dry separation during manure collection, a first outlet and a second outlet are constructed on the same side of the outer horizontal direction of the manure collection trough 4 to discharge liquid and dry materials respectively. The first outlet is connected to the liquid inlet 43, and the second outlet is connected to the dry material inlet 51. The liquid inlet 43 is located on the wet fermentation tank 6, and the dry material inlet 51 is located on the dry fermentation tank 5. Specifically, a liquid collection trough 41 parallel to the partition wall 11 is constructed vertically in the middle of the manure collection trough 4, connecting to the first outlet; a filter screen cover 42 is provided on the liquid collection trough 41. To facilitate the separation of wet and dry excrement during collection, the bottom plate of the pen is inclined towards the manure outlet 12 for easy collection. The bottom of the manure collection trough 4 is inclined towards the liquid collection trough 41 with the liquid collection trough 41 as the middle boundary. The side closer to the pen is inclined towards the liquid collection trough 41 and also towards the liquid inlet 43. The side farther from the pen is inclined towards the edge of the manure collection trough 4 and also towards the dry material inlet 51.

[0019] Thus, when piglets produce feces and urine, because the floor of the pen is set towards the manure outlet 12, the urine will first flow out of the manure outlet 12 and fall into the manure collection trough 4. Since the bottom of the manure collection trough 4 is inclined towards the liquid collection trough 41 with the pen side as the middle boundary, the urine will flow into the liquid collection trough 41 and finally enter the wet fermentation tank 6 through the liquid inlet 43 for liquid fermentation or other treatment. Dry manure will not be automatically collected into the manure collection trough 4. At this time, manual collection is required. The manure is collected into the manure collection trough 4 and piled up, and then enters the dry fermentation tank 5 through the dry feed inlet 51 for fermentation to form organic fertilizer.

[0020] Thus, this device uses a manure collection trough 4 lower than the pigpen to temporarily store manure. The bottom of the pigpen is tilted, and a liquid collection trough 41 is placed in the middle of the manure collection trough 4 to collect liquid first. The bottom of the manure collection trough 4 is also tilted accordingly, achieving liquid collection first, then solid collection, thus separating the manure into wet and dry components. The manure is then sorted and sent to appropriate fermentation tanks for fermentation or other treatment, avoiding the generation of large amounts of foul odors from mixing wet and dry excrement during fermentation. Furthermore, this application does not use other equipment to assist in the separation of wet and dry components; it achieves separation entirely through the structural design of the pigpen, making it suitable for small-scale farming and avoiding the inconvenience of using equipment.

[0021] In one embodiment, the bottom plate of the pen at the manure outlet 12 is set to be arc-shaped to facilitate the dropping of feces into the manure collection trough 4.

[0022] In one embodiment, the length of the liquid collection tank 41 is two-thirds of the vertical length of the feces collection tank 4 to facilitate the feeding of dry feces into the dry material inlet 51. At the same time, the other one-third area also serves as a temporary storage area for dry feces, which also facilitates the filtration of liquid.

[0023] In one embodiment, the liquid collection tank 41 is provided with a step, and the filter cover 42 is detachably placed on the step, which facilitates disassembly and cleaning.

[0024] In one embodiment, a filter plate 44 is provided inside the liquid inlet 43 to prevent a large amount of dry feces from entering the wet fermentation tank 6.

[0025] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
