Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of composting fermentation barrels, in particular to a manure composting fermentation barrel. Background Art
[0002] Dairy farms generate large amounts of manure during operation. If not promptly treated, this manure not only severely impacts the farm's sanitation but can also pollute the surrounding ecosystem. Therefore, the treatment of dairy farm manure has become a pressing issue. Composting, as an effective manure treatment method, can convert dairy farm manure into organic fertilizer, enabling resource reuse while reducing environmental pollution.
[0003] The existing compost barrel consists of a barrel body and a barrel lid. A partition with filter holes is provided in the barrel body to separate the inner cavity of the barrel body into an upper compost chamber and a lower liquid fertilizer chamber. The upper part of the barrel body is provided with an opening connected to the compost chamber, and the barrel lid can cover the opening. The lower part of the barrel body is provided with a liquid outlet connected to the liquid fertilizer chamber. A liquid outlet valve is provided at the liquid outlet to perform anaerobic fermentation on the feces placed in the compost barrel to decompose the organic matter in the feces. However, compost barrels with existing structures usually do not have a heating function. They only rely on the heat energy generated by the decomposition of the feces themselves due to the ambient temperature to promote the reproduction and fermentation of microorganisms. When the ambient temperature is low, especially in the cold winter, compost barrels with this structure cannot perform normal fermentation of feces. In addition, water evaporates during the decomposition process of the compost barrel. The evaporated water gathers on the barrel lid, which will cause the humidity in the upper part of the barrel body to be higher. The different humidity levels of the compost in the barrel body affect the composting effect. Furthermore, the ventilation time will also affect the composting effect. Utility Model Content
[0004] The purpose of the utility model is to provide a manure composting fermentation barrel, which is easy to use, is not affected by the temperature and humidity of the environment, can accelerate the fermentation and decomposition of cow manure, and can shorten the fermentation period.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A manure compost fermentation barrel comprises an outer barrel body, an inner barrel body and a barrel cover. The inner barrel body is arranged inside the outer barrel body, and the barrel cover is rotatably connected to one side of the outer barrel body. The barrel cover is provided with an inner cover plate for covering the opening of the inner barrel body. The upper surface of the inner cover plate is horizontal and the lower surface is inclined. The thickness of the inner cover plate is the largest near the side where the outer barrel body and the barrel cover are rotatably connected. A liquid collecting component is provided at the place where the thickness of the inner cover plate is the largest.
[0007] Preferably, the liquid collecting assembly includes a liquid conducting groove transversely arranged at the thickest end of the barrel cover and a water collecting groove connected to the liquid conducting groove and arranged between the inner barrel body and the outer barrel body, and the liquid conducting groove and the water collecting groove are connected through a hose.
[0008] Preferably, a closed chamber is formed between the liquid guiding groove and the top plate, and a strip opening is provided at the top of the chamber away from the connection side between the outer barrel body and the barrel cover.
[0009] Preferably, an air inlet and an air outlet are provided on the outer barrel body, the air inlet is connected to a heating pipe, and the heating pipe blows hot air into the air inlet through a blower.
[0010] Preferably, a filter grate with filter holes is provided at the lower part of the inner barrel body, and the filter grate separates the inner barrel body into a compost bin and a liquid fertilizer bin. A liquid fertilizer port is provided at the bottom of the liquid fertilizer bin, and the liquid fertilizer port is connected to a sleeve and extends to the outside of the outer barrel body through the sleeve. A liquid fertilizer valve is provided on the sleeve.
[0011] Preferably, a first fertilizer outlet is provided on one side of the lower portion of the compost bin, a second fertilizer outlet is provided on the side of the outer barrel corresponding to the first fertilizer outlet, a passage is connected between the first fertilizer outlet and the second fertilizer outlet, and an outer cover is provided on the second fertilizer outlet.
[0012] Preferably, the barrel cover is provided with a first clip on the side away from the rotational connection with the outer barrel body, and the first clip is used to achieve a sealed connection between the barrel cover and the outer barrel body; a second clip is provided on the left and right sides of the outer cover respectively, and the second clip is used to achieve a sealed connection between the outer cover and the outer barrel body.
[0013] Preferably, sealing rings are provided inside the barrel cover and the outer cover.
[0014] Preferably, it also includes a ventilation duct, which runs through the outer barrel and the inner barrel, and a plurality of ventilation holes are provided on the ventilation duct in the inner barrel, and both ends of the ventilation duct are provided with blockages.
[0015] Preferably, a heat-insulating layer is provided in the inner barrel body; and an exhaust valve and a thermometer are provided on the barrel cover.
[0016] In the above technical solution, the barrel lid is provided with an inner cover plate for covering the opening of the inner barrel body. The upper surface of the inner cover plate is horizontal and the lower surface is inclined to form a slope. When the fermentation barrel is used to ferment manure, the water evaporated during the fermentation process gathers on the inner cover plate and slides down the slope of the inner cover plate to the thickest end of the inner cover plate, and then gathers in the liquid guide groove. The liquid guide groove is fixedly connected to the inner cover plate on all sides to form a closed space between the inner cover plate and the inner cover plate. In order to allow all the water gathered on the inner cover plate to flow into the liquid guide groove, a strip opening is provided at the top of the liquid guide groove away from the connection between the outer barrel body and the barrel lid. Even when the barrel lid is opened, the gathered water still flows into the liquid guide groove along the inner wall of the barrel lid, rather than directly into the fermentation barrel, ensuring that the water in the fermentation barrel does not gather on the top of the compost and affect the composting effect. Furthermore, the liquid guide trough is connected to the water collection trough through a hose. When a large amount of water is collected in the liquid guide trough, the water flows into the water collection trough through the hose. The water collection trough is arranged between the inner barrel and the outer barrel. When the water in the water collection trough overflows, it will not flow back into the inner barrel and affect the composting, making the composting effect of the fermentation barrel better. By providing a drain port at the bottom of the outer barrel, when the water in the water collection trough overflows, it can flow out through the drain port and will not accumulate in the outer barrel. This makes the fermentation barrel unaffected by humidity and more convenient for fermentation.
[0017] The heat energy generated by the decomposition of feces by the ambient temperature alone promotes the reproduction and fermentation of microorganisms. When the ambient temperature is low, the compost fermentation barrel cannot ferment the feces normally. By providing a through air inlet and air outlet on the outer wall of the outer barrel, the air inlet is connected to a heating pipe, and the heating pipe blows hot air into the air inlet through a blower, the inner barrel body is heated by external means to keep it at a suitable temperature, which is more convenient for the fermentation of feces in the fermentation barrel, so that the fermentation barrel is not affected by the ambient temperature, and can accelerate the fermentation and decomposition of feces and shorten the fermentation cycle.

DETAILED DESCRIPTION
[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figures 1 to 4 As shown, the manure composting fermentation barrel includes an outer barrel body 1, within which an inner barrel body 3 is disposed. The inner barrel body 3 is provided with an insulation layer to insulate the manure stored in the inner barrel body 3. A barrel lid 4 is rotatably connected to one side of the top of the outer barrel body 1. The barrel lid 4 is provided with an inner cover plate 43 for covering the opening of the inner barrel body 3. The upper surface of the inner cover plate 43 is horizontal and the lower surface is inclined. The inner cover plate 43 is thickest near the side of the outer barrel body 1 and the barrel lid 4 where it is rotatably connected. A liquid collection assembly is provided at the thickest part of the inner cover plate 43. The lower surface of the inner cover plate 43 is inclined to form a slope. When the fermentation barrel is used to ferment manure, the water evaporated during the fermentation process gathers on the inner cover plate 43 and slides down the slope of the inner cover plate 43 to the thickest end of the inner cover plate 43. It then gathers in the liquid guide groove 45. The liquid guide groove 45 is fixedly connected to the inner cover plate 43 on all sides, forming a closed chamber between the inner cover plate 43. To ensure that all the water collected on the inner cover plate 43 can flow into the liquid guide groove 45, a strip opening 46 is provided at the top of the liquid guide groove 45 away from the connection between the outer barrel body 1 and the barrel lid 4. Even when the barrel lid 4 is opened, the collected water still flows into the liquid guide groove 45 along the inner wall of the barrel lid 4, rather than directly into the fermentation barrel, ensuring that the water in the fermentation barrel does not accumulate on the top of the compost and affect the composting effect. Furthermore, the liquid conducting groove 45 is connected to the water collecting groove 51 through a hose 5. One end of the hose 5 is fixedly installed on the side wall of the liquid conducting groove 45, and the hose 5 passes through the side wall of the inner barrel body 3. The other end of the hose 5 is fixedly installed in the side wall of the water collecting groove 51. When there is a lot of water gathered in the liquid conducting groove 45, the water flows into the water collecting groove 51 through the hose 5. The water collecting groove 51 is fixedly connected between the outer barrel body 1 and the inner barrel body 3. When the water in the water collecting groove 51 overflows, it will not flow back to the inner barrel body 3 to affect the fermentation, so that the composting effect of the fermentation barrel is better. A drain port 22 is provided at the bottom of the outer barrel body 1. When the water in the water collecting groove 51 overflows, it can flow out through the drain port 22 and will not gather inside the outer barrel body 1, so that the fermentation barrel is not affected by humidity and is more convenient for fermentation.
[0025] In this embodiment, a sealing ring is provided inside the barrel cover 4 to prevent air from entering the inner barrel body 3 through the gap of the barrel cover 4 and affecting the fermentation of feces. An exhaust valve 41 is provided on the barrel cover 4 for exhausting air during the fermentation process. A thermometer 42 is also provided on the barrel cover 4 for measuring the fermentation temperature. The barrel cover 4 is provided on the top of the outer barrel body 1 and forms a closed space with the outer barrel body 1. The barrel cover 4 and the outer barrel body 1 are rotatably connected by a hinge. A first clip 23 is provided on the side of the barrel cover 4 and the outer barrel body 1 away from the hinge. The barrel cover 4 and the outer barrel body 1 are sealed by the first clip 23 to facilitate opening and closing. At the same time, there will be no separation between the outer barrel body 1 and the barrel cover 4, which is more convenient to use. A support rod 6 is further provided between the outer barrel body 1 and the barrel cover 4. The support rod 6 includes a first support rod 61 rotatably connected to both sides of the top of the outer barrel body 1 and a second support rod 62 rotatably connected to both sides of the barrel cover 4. The first support rod 61 and the second support rod 62 are rotatably connected. When the barrel cover 4 is opened, the support rod 6 rotates and supports between the barrel cover 4 and the outer barrel body 1 to maintain the barrel cover 4 in this position, which makes it easier to add feces and other objects into the outer barrel body 1.
[0026] In this embodiment, a filter grate 47 with filter holes is provided at the bottom of the inner barrel 3. This filter grate 47 separates the inner barrel 3 into a compost bin 48 and a liquid fertilizer bin 49, separating the compost from the liquid fertilizer. A liquid fertilizer inlet is provided at the bottom of the liquid fertilizer bin 49. This inlet is connected to a sleeve 491 and extends through the sleeve 491 to the outside of the outer barrel 1. A liquid fertilizer valve 492 is provided on the sleeve 491. The opening and closing of the liquid fertilizer valve 492 controls the flow of liquid fertilizer. A first fertilizer outlet 31 is provided at the bottom of the compost bin 48. A second fertilizer outlet 15 is provided on the outer barrel 1 corresponding to the first fertilizer outlet 31. A passage 24 connects the first fertilizer outlet 31 and the second fertilizer outlet 15. An outer cover 2 is provided on the side of the second fertilizer outlet 15. A sealing ring is also provided inside the outer cover 2 to prevent air from entering through the gap in the outer cover 2, thereby improving the insulation of the inner barrel 3. The outer cover 2 is arranged above the filter grate 47 to leave an outlet for the compost, so there is no need to take the compost out from the barrel cover 4, which is convenient for use. At the same time, second clips 21 are respectively provided on the left and right sides of the outer cover 2. The second clips 21 are used to achieve a sealed connection between the outer cover 2 and the inner barrel body 3.
[0027] In a preferred embodiment, a ventilation duct 7 is further included, which passes through the outer barrel body 1 and the inner barrel body 3, and a plurality of ventilation holes are provided at the lower part of the ventilation duct 7 in the inner barrel body 3, and plugs 71 are provided at both ends of the ventilation duct 7, which can be opened or closed as needed.
[0028] Relying solely on the heat energy generated by the decomposition of cow manure by the ambient temperature to promote the growth and fermentation of microorganisms, when the ambient temperature is too low, the compost barrel cannot normally ferment the cow manure. In a preferred embodiment, a through air inlet 11 and an air outlet 12 are provided on the outer wall of the outer barrel body 1. The air inlet 11 is connected to a heating pipe, and the heating pipe blows hot air into the air inlet 11 through a blower. The inner barrel body 3 is heated by external means to maintain it at a suitable temperature, which is more convenient for the fermentation of cow manure in the fermentation barrel. The fermentation barrel is not affected by the ambient temperature, and can accelerate the fermentation and decomposition of manure, shortening the fermentation cycle. In this embodiment, a timing device can also be added to control the opening time of the blower and the heating pipe 13 by the timing device, thereby improving intelligence.
[0029] When using this fermentation barrel, the barrel lid 4 is first opened, and cow manure mixed with other substances in a specific ratio is added to the interior of the inner barrel body 3. The barrel lid 4 is then closed and the first clamping member 23 is locked. During the fermentation process, the need for ventilation or heating is determined based on the temperature displayed by the thermometer 42. When fermentation is complete, the outer lid 2 is opened, the compost in the compost bin 48 is cleared out, and the liquid fertilizer in the liquid fertilizer bin 49 is taken out through the liquid fertilizer valve 492.
[0030] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
