For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0030] Combine the following Figures 1 to 4 The utility model describes a feces-sewage solid-liquid separation system and an ecological toilet.
[0031] like Figure 1 and Figure 2 As shown, the feces solid-liquid separation system shown in this embodiment includes: a fermentation barrel 1, a cylinder 2, a filtering device 3 and a liquid fermentation chamber 4.
[0032] The cylinder 2, the filter device 3 and the liquid fermentation chamber 4 are all arranged in the fermentation barrel 1, and the cylinder 2, the filter device 3 and the liquid fermentation chamber 4 are arranged in sequence from top to bottom along the height direction of the fermentation barrel 1; the sewage pipe 53 of the toilet system 5 is connected to the fermentation barrel 1, and the outlet of the sewage pipe 53 in the fermentation barrel 1 is above the filter device 3 and located on the outside of the cylinder 2, the filter device 3 has a filter hole 31 penetrating in the vertical direction, the filter hole 31 is connected to the inlet of the liquid fermentation chamber 4, and a liquid outlet 431 is provided at the bottom of the liquid fermentation chamber 4.
[0033] Specifically, the feces solid-liquid separation system shown in this embodiment is achieved by modifying the existing toilet system 5 in rural areas, receiving the excrement in the toilet system 5 and performing solid-liquid separation. After fermentation, the separated solid matter can be fermented and used as organic fertilizer, and the separated liquid matter can be used to irrigate farmland.
[0034] Specifically, if Figure 2 As shown, the feces and sewage in the toilet system 5 enter the fermentation barrel 1 through the sewage pipe 53 of the toilet system 5. The sewage pipe 53 is located at the outlet of the fermentation barrel 1, which is located above the filter device 3 and on the outside of the cylinder 2. After the solid matter in the feces and sewage enters the fermentation barrel 1, it can be accumulated on the filter device 3 and fermented. Under the action of gravity, the liquid matter in the feces and sewage enters the liquid fermentation chamber 4 through the filter hole 31 of the filter device 3. The filter device 3 can prevent the solid matter from entering the liquid fermentation chamber 4; the liquid matter ferments in the liquid fermentation chamber 4, and after a certain period of fermentation, it can be discharged through the liquid outlet 431 and used to irrigate farmland, reducing the consumption of water resources. At the same time, the solid matter in the fermentation barrel 1 can be used as organic fertilizer after fermentation, realizing the effective utilization of nutrients in the feces and sewage.
[0035] In some embodiments, when the connection port of the sewage pipe 53 and the toilet system 5 is lower than the connection port of the sewage pipe 53 and the fermentation barrel 1, in order to ensure that the feces in the toilet system 5 can enter the fermentation barrel 1, Figure 2 As shown, the sewage pipe 53 shown in this embodiment is provided with a negative pressure fan 6. When the negative pressure fan 6 is turned on, negative pressure is formed in the sewage pipe 53 between the negative pressure fan 6 and the toilet system 5, so that the feces and sewage in the toilet system 5 are sucked into the fermentation barrel 1 through the sewage pipe 53.
[0036] In some embodiments, Figure 2 and Figure 3 As shown, the liquid fermentation chamber 4 shown in this embodiment includes: a first chamber 41, a second chamber 42 and a third chamber 43; the filter hole 31 of the filter device 3 is connected to the first chamber 41, the first chamber 41 is connected to the second chamber 42 through a first overflow pipe 71, the second chamber 42 is connected to the third chamber 43 through a second overflow pipe 72, and the liquid outlet 431 is arranged at the bottom of the third chamber 43.
[0037] It can be understood that in this embodiment, three chambers are provided and the harmless principle of a three-compartment septic tank is utilized to allow the liquid portion of the feces and sewage from the toilet system 5 to be sealed and fermented.
[0038] Specifically, the liquid matter and a small amount of solid matter in the feces first enter the first chamber 41. Correspondingly, parasite eggs and solid matter with a larger specific gravity will be deposited in the first chamber 41, and the liquid matter will be initially fermented and decomposed in the first chamber 41; after the liquid level in the first chamber 41 rises to a certain height, the initially decomposed liquid in the first chamber 41 enters the second chamber 42 through the first overflow pipe 71, and the feces skin floating in the first chamber 41 and the deposited residue continue to remain in the first chamber 41 for further fermentation; in the second chamber 42, the liquid continues to ferment and decompose, and the parasite eggs continue to be further deposited. The pathogens in the liquid gradually die to achieve further harmless treatment of the liquid. After the liquid level in the second chamber 42 rises to a certain height, the liquid in the second chamber 42 enters the third chamber 43 through the second overflow pipe 72. The bacteria and parasite eggs in the liquid entering the third chamber 43 from the second chamber 42 have been basically killed, and the liquid outlet 431 of the third chamber 43 is in a closed state. At this time, the liquid in the third chamber 43 can be temporarily stored. When it is necessary to fertilize the farmland, the staff can open the liquid outlet 431 to obtain the liquid in the third chamber 43 for irrigation and other treatments.
[0039] In some embodiments, Figure 3 As shown, the fermentation barrel 1 shown in this embodiment is cylindrical, and the first chamber 41, the second chamber 42 and the third chamber 43 are arranged along the circumference of the fermentation barrel 1; the projection shape of the first chamber 41, the second chamber 42 and the third chamber 43 on the plane perpendicular to the axis of the fermentation barrel 1 is fan-shaped.
[0040] Specifically, by setting the cross-sectional shape of the first chamber 41, the second chamber 42 and the third chamber 43 to be fan-shaped, and at the same time, the first chamber 41, the second chamber 42 and the third chamber 43 are arranged along the circumference of the fermentation barrel 1, compared with the traditional three-compartment septic tank, the floor space of the liquid fermentation chamber 4 is reduced while meeting the liquid fermentation needs.
[0041] The first chamber 41 , the second chamber 42 and the third chamber 43 are divided by three partitions, and the three partitions are arranged along the circumference of the fermentation barrel 1 , and two adjacent partitions and the inner wall of the fermentation barrel 1 enclose one of the chambers.
[0042] In some embodiments, Figure 2 As shown, the liquid inlet of the first overflow pipe 71 shown in this embodiment is located on the upper side of the liquid outlet of the first overflow pipe 71 along the height direction of the fermentation barrel; the liquid inlet of the second overflow pipe 72 is located on the upper side of the liquid outlet of the second overflow pipe 72 along the height direction of the fermentation barrel.
[0043] Specifically, since the liquid inlet of the first overflow pipe 71 is higher than the liquid outlet, when the liquid level in the first chamber 41 reaches the liquid inlet of the first overflow pipe 71, the liquid can be discharged into the second chamber 42 through the liquid outlet of the first overflow pipe 71 under the action of gravity; similarly, since the liquid inlet of the second overflow pipe 72 is higher than the liquid outlet, when the liquid level in the second chamber 42 reaches the liquid inlet of the second overflow pipe 72, the liquid can enter the third chamber 43 through the second overflow pipe 72 under the action of gravity; the first overflow pipe 71 is arranged on the partition between the first chamber 41 and the second chamber 42, and the second overflow pipe 72 is arranged on the partition between the second chamber 42 and the third chamber 43.
[0044] In some embodiments, Figure 2 As shown, the filtering device 3 shown in this embodiment includes: a perforated plate. The perforated plate is used to stop solid substances in feces and sewage, and filtering holes 31 are arranged on the perforated plate. Liquid substances in feces and sewage are used to enter the liquid fermentation chamber 4 through the filtering holes 31.
[0045] Specifically, the perforated plate separates the fermentation barrel 1 into two parts, the cylinder 2 is located in the upper part, and the liquid fermentation chamber 4 is located in the lower part; the feces in the fermentation barrel 1 falls on the upper surface of the perforated plate under the action of gravity, and the aperture of the filter hole 31 is smaller than the particle size of the solid matter in the feces, so that the solid matter can be stopped on the upper surface of the perforated plate, and the liquid matter can flow into the first chamber 41 through the through hole for preliminary fermentation and decomposition.
[0046] In some embodiments, Figure 2 As shown, a spiral conveying mechanism 8 is provided in the barrel 2 shown in this embodiment; the barrel 2 is arranged along the height direction of the fermentation barrel 1, the inlet of the barrel 2 is formed at the upper port of the barrel 2, and the outlet of the barrel 2 is formed at the lower port of the barrel 2; the spiral conveying mechanism 8 is arranged along the axial direction of the barrel 2.
[0047] Specifically, by arranging the screw conveying mechanism 8 in the cylinder 2, the feces and sewage are conveyed toward the side close to the perforated plate, thereby improving the conveying efficiency of the feces and sewage.
[0048] Among them, the spiral conveying mechanism 8 includes a rotating shaft 81 and a conveyor belt 82. The axis of the rotating shaft 81 coincides with the axis of the cylinder 2. The conveyor belt 82 extends spirally along the axis direction of the rotating shaft 81. The conveyor belt 82 is connected to the rotating shaft 81. The driving motor 83 on the fermentation barrel 1 is connected to the rotating shaft 81.
[0049] In addition, in order to facilitate the removal of the solid part of the feces from the cylinder 2, the top of the cylinder 2 extends beyond the top outside of the fermentation barrel 1, and the part of the cylinder 2 that extends upward beyond the top outside of the fermentation barrel 1 is provided with a discharge port 93. Therefore, after the screw conveying mechanism 8 runs and drives the solid part of the feces to move upward, these fixed parts can be discharged from the discharge port 93.
[0050] In some embodiments, based on the principle of aerobic composting, in order to further improve the fermentation efficiency of the solid part in the fermentation tank 1, Figure 2 and Figure 4 As shown, the manure solid-liquid separation system shown in this embodiment also includes: an aeration pipe 91 and an aeration fan 92; the aeration pipe 91 is arranged on the conveying belt 82 of the spiral conveying mechanism 8, and a plurality of aeration holes 911 are arranged on the aeration pipe 91; the aeration pipe 91 is connected to the aeration fan 92.
[0051] Specifically, by arranging the aeration pipe 91 on the conveyor belt 82 so that the aeration pipe 91 is in contact with the feces in the cylinder 2, the aeration fan 92 can input sufficient oxygen into the interior of the feces through the aeration holes 911 on the aeration pipe 91, thereby improving the fermentation efficiency of the feces and avoiding the phenomenon of anaerobic fermentation.
[0052] In some embodiments, Figure 2 As shown, the barrel 2 shown in this embodiment is conical, and the diameter of the barrel 2 at one end close to the liquid fermentation chamber 4 is larger than the diameter of the barrel 2 at one end away from the liquid fermentation chamber 4.
[0053] Specifically, by setting the cylinder 2 to be conical, the cylinder 2 as a whole has a thicker structure at the bottom and thinner at the top, that is, the inlet of the cylinder 2 is smaller than the outlet of the cylinder 2, so that during the conveying process of the spiral conveying mechanism 8, blockage in the cylinder 2 is effectively avoided.
[0054] Furthermore, a plurality of universal wheels 11 are provided at the bottom of the fermentation barrel 1 to facilitate the movement of the fermentation barrel 1 .
[0055] like Figure 1 As shown, this embodiment also provides an ecological toilet, including: a toilet system 5 and the feces solid-liquid separation system as described above; the sewage pipe of the toilet system 5 is connected to the fermentation barrel 1, and the outlet of the sewage pipe in the fermentation barrel 1 is located above the filter device 3 and on the outside of the cylinder 2.
[0056] Since the ecological toilet adopts the feces and sewage solid-liquid separation system shown in the above embodiment, the specific structure of the feces and sewage solid-liquid separation system refers to the above embodiment. Since the ecological toilet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
[0057] like Figure 1As shown, the toilet system 5 shown in this embodiment includes: a toilet bowl 51 and a water tank 52 ; the sewage pipe 53 of the toilet system 5 is connected to the fermentation barrel 1 , and the outlet of the water tank 52 is connected to the toilet bowl 51 .
[0058] Specifically, one end of the sewage pipe 53 is connected to the outlet of the toilet 51, and the other end is connected to the fermentation barrel 1. The inlet of the water tank 52 can be connected to an external water pipe, and the outlet of the water tank 52 is connected to the toilet. The water in the water tank 52 can enter the toilet 51 through the outlet of the water tank 52.
[0059] By renovating existing toilets in rural areas, the feces and sewage after flushing in the toilet bowl 51 enter the feces and sewage solid-liquid separation system for fermentation and decomposition, and are treated separately, and will not be directly discharged to the outside, which can reduce the waste of water resources.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
