Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composting, and particularly provides a multi-bin circulating composting barrel. BACKGROUND

[0002] The household "sandwich composting method" refers to using a barrel-shaped container as a composting barrel, stacking kitchen waste and soil in the composting barrel layer by layer until the composting barrel is filled, allowing the kitchen waste to remain stationary after the composting barrel is filled, and allowing the kitchen waste to continue to ferment under the decomposition of microorganisms until it is completely decomposed. The soil can be farmland soil or humus soil formed after plant residues are decomposed, and the soil functions to retain moisture and prevent odor.

[0003] The specific operation of the traditional composting method is as follows: first, a layer of humus soil is laid on the bottom of the composting barrel, and then a layer of kitchen waste is laid on it; this is repeated until the composting barrel is filled. When the composting barrel is filled, no more kitchen waste and humus soil can be added, and all the materials must be removed before new kitchen waste and humus soil can be added for composting. However, when the kitchen waste at the top is completely decomposed, it means that the kitchen waste that was added to the bottom earlier has already decomposed into humus soil and cannot be removed because there is still un-decomposed kitchen waste at the top. This results in new kitchen waste being unable to enter the composting barrel for fermentation and decomposition, which not only wastes space in the barrel but also affects the efficiency of composting. Additionally, the installation of a material removal hatch on the side wall of the bottom of the composting barrel increases the risk of liquid leakage and makes it easy to soil the floor when removing the material.

[0032] Embodiments of the present application are described below in detail with reference to examples shown in the drawings, wherein the same or similar numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and are not understood as limiting the present application.

[0034] In addition, the terms "first", "second" are only for descriptive purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.

[0035] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] The household "sandwich composting method" refers to using a barrel-shaped container as a compost bucket, stacking kitchen waste and soil layer by layer in the compost bucket until the compost bucket is full. After filling the compost bucket, the kitchen waste is left to stand. During the standing period, the kitchen waste will continue to ferment under the decomposition of microorganisms until it is completely decomposed. The soil can be farmland soil or humus formed by decomposing plant residues. The function of the soil is to retain moisture and prevent odor. The specific operation of the traditional composting method is: first spread a layer of humus on the bottom of the compost bucket, and then spread a layer of kitchen waste; repeat this process until the compost bucket is full. When the compost bucket is full, no more kitchen waste and humus can be added. It is necessary to wait until the kitchen waste on the top is completely decomposed and all materials are taken out before adding kitchen waste and humus again for composting. However, when the kitchen waste on the top is completely decomposed, it means that the kitchen waste previously filled in the bottom has already decomposed into humus, but it cannot be taken out because there is still undecomposed kitchen waste on the top; this results in the new kitchen waste being unable to enter the compost bin for fermentation and decomposition, which not only wastes space in the bin but also affects the composting efficiency. Setting a material extraction hatch on the side wall at the bottom of the compost bin will increase the risk of leakage and easily dirty the floor when taking out the material.

[0037] Based on the above considerations, in order to solve the problem of low composting efficiency of the composting barrels in the related art, a multi-bin circulating composting barrel is designed, which uses a ventilation tube and at least three partition plates to separate at least three fermentation barrels in the barrel body. Thus, at least three fermentation barrels can be used for cyclic composting. For example, the first fermentation barrel can be used for composting and fermentation, the second fermentation barrel can be pre-filled with humus soil, and then the third empty fermentation barrel can be used to fill the humus soil in the second fermentation barrel and the external kitchen waste in sequence, so that the third fermentation barrel is composted and the second fermentation barrel is empty. After the first fermentation barrel is mature, compost is carried out in the second fermentation barrel in the above manner. Circular composting is achieved in this way, which effectively improves the composting efficiency of the multi-bin circulating composting barrel, and the first air hole opened on the ventilation tube and the second air hole opened on the partition plate can form ventilation and air permeability to make the kitchen waste present in an aerobic fermentation state, thereby further improving the composting efficiency.

[0038] Below, the multi-bin circulating composting barrel provided by the present application will be described in detail based on specific embodiments.

[0039] Please refer to Figures 1 to 6The embodiment of the present application provides a multi-bin circulating compost barrel 1000, which comprises a barrel body 100, a barrel cover 200, a ventilation pipe 300 and at least three partition plates 400, one end of the ventilation pipe 300 is connected to the inner bottom wall of the barrel body 100, the other end of the ventilation pipe 300 is directed outward along the depth direction D of the barrel body 100; a plurality of first ventilation holes 301 are formed in the ventilation pipe 300; the partition plates 400 are connected to the inner bottom wall of the ventilation pipe 300, the inner bottom wall of the barrel body 100 and the inner side wall of the barrel body 100 respectively, and the space between the barrel body 100 and the ventilation pipe 300 is divided into at least three fermentation bins 101 by the at least three partition plates 400; a plurality of second ventilation holes 401 are formed in the partition plates 400; the barrel cover 200 is arranged at the end of the barrel body 100, and the barrel cover 200 is provided with a ventilation structure 210 corresponding to the ventilation pipe 300.

[0040] The barrel body 100 refers to a barrel structure with an open end and an internal accommodating space. The barrel body 100 includes but is not limited to a metal barrel body 100 (for example, a stainless steel barrel body 100, an aluminum barrel body 100, etc.), an injection molded barrel body 100, etc.

[0041] The barrel cover 200 is used for covering the barrel body 100, so that the internal space of the barrel body 100 can be in a relatively closed state. The barrel cover 200 is provided with a ventilation structure 210, which can be but is not limited to a mesh structure, a porous structure or the like. Air is introduced into the barrel body 100 through the ventilation structure 210, so that the kitchen waste can improve the fermentation rate.

[0042] The ventilation pipe 300 is a long strip-shaped pipe structure, one end of the ventilation pipe 300 is connected to the inner bottom wall of the barrel body 100, the other end of the ventilation pipe 300 is directed outward along the depth direction D of the barrel body 100, and a plurality of first ventilation holes 301 are formed in the ventilation pipe 300; it should be understood that when the barrel cover 200 is arranged on the barrel body 100, one end of the ventilation pipe 300 can be directed to the ventilation structure 210 on the barrel cover 200, so that the ventilation pipe 300 can be in communication with the outside through the ventilation structure 210; and then the ventilation pipe 300 can be connected to the internal fermentation bin 101 through the first ventilation hole 301, so that the kitchen waste is in an aerobic fermentation state to further improve the fermentation efficiency.

[0043] The partition plate 400 is used for dividing the space in the barrel body 100, for example, the number of partition plates 400 can be three, four or more, and the partition plate 400 can divide the space between the barrel body 100 and the ventilation pipe 300 into three, four or more fermentation bins 101. The second ventilation hole 401 arranged on the partition plate 400 can further improve the ventilation effect in the fermentation bin 101, so as to improve the fermentation speed.

[0044] The multi-bin circulating composting barrel 1000 provided by the embodiments of the present application utilizes the air permeable pipe 300 and at least three partition plates 400 to divide the barrel body 100 into at least three fermentation bins 101, so that composting can be performed in the at least three fermentation bins 101 in a circulating manner. For example, composting fermentation can be performed in the first fermentation bin 101, the second fermentation bin 101 is filled with humus in advance, and then the third empty fermentation bin 101 is filled with humus in the second fermentation bin 101 and external kitchen waste in sequence, so that the third fermentation bin 101 performs composting and the second fermentation bin 101 is empty, and then composting is performed in the second fermentation bin 101 in the above manner after the first fermentation bin 101 is matured. In this way, the composting efficiency of the multi-bin circulating composting barrel 1000 is effectively improved, and the first air permeable hole 301 formed in the air permeable pipe 300 and the second air permeable hole 401 formed in the partition plate 400 can form ventilation and air permeability to make the kitchen waste in an aerobic fermentation state, so as to further improve the composting efficiency.

[0045] It should be understood that in other embodiments, the multi-bin circulating composting barrel 1000 can also be used as a planting barrel. By filling the soil in the multiple fermentation bins 101, planting operations can be performed, and under the action of the air permeable pipe 300, the soil in each fermentation bin 101 can contact air in a larger area, thereby effectively reducing the probability of plant root rot.

[0046] Please refer to Figures 1 to 6 In some embodiments, the multi-bin circulating composting barrel 1000 further comprises a long-handled spoon 500, and the long-handled spoon 500 is accommodated in the air permeable pipe 300.

[0047] It can be understood that the hollow area inside the air permeable pipe 300 can accommodate the long-handled spoon 500, and when the barrel cover 200 is opened and the humus and kitchen waste inside need to be operated, the long-handled spoon 500 can be used for digging operation, so as to effectively improve the convenience of use.

[0048] It should be understood that when the long-handled spoon 500 is accommodated, the spoon end of the long-handled spoon 500 can be inserted into the air permeable pipe 300, so that the long handle end of the long-handled spoon 500 is exposed outside the air permeable pipe 300, so as to facilitate the user's taking and placing operation.

[0049] Please refer to Figures 1 to 6 In some embodiments, the air permeable structure 210 comprises a pipe body part 211 arranged on the side of the barrel cover 200 away from the barrel body 100, and a shielding part 212 arranged at the end of the pipe body part 211 away from the barrel cover 200, and a plurality of third air permeable holes 213 are formed in the pipe body part 211; and part of the long-handled spoon 500 is accommodated in the pipe body part 211.

[0050] The pipe body 211 is arranged on the side of the lid 200 away from the barrel body 100, so that when the length of the long-handled spoon 500 is long, the hollow area inside the pipe body 211 can form an avoiding space, and part of the long handle of the long-handled spoon 500 can be inserted into the pipe body 211 for accommodation.

[0051] The pipe body 211 is arranged on the side of the lid 200 away from the barrel body 100, so that when the length of the long-handled spoon 500 is long, the hollow area inside the pipe body 211 can form an avoiding space, and part of the long handle of the long-handled spoon 500 can be inserted into the pipe body 211 for accommodation.

[0052] The shielding part 212 is used to shield the pipe body 211 to reduce the probability of rainwater entering the barrel body 100 from the third air holes 213 on the pipe body 211. Optionally, the shielding part 212 can be, but is not limited to, a shielding block, a shielding plate, a shielding cover, etc. Optionally, in some embodiments, the projection of the shielding part 212 in the direction of gravity contains the projection of the pipe body 211 in the direction of gravity.

[0053] Please refer to Figures 1 to 6 In some embodiments, the height of the air pipe 300 along the depth direction D of the barrel body 100 is less than the depth of the barrel body 100.

[0054] It can be understood that when one end of the air pipe 300 is connected to the inner bottom wall of the barrel body 100, the other end of the air pipe 300 faces the outside of the barrel body 100 and does not protrude out of the barrel body 100; in this way, when the lid 200 is placed on the barrel body 100, a gap will be formed between the air pipe 300 and the lid 200.

[0055] In this way, when external air is introduced into the barrel body 100 through the air-permeable structure 210 on the lid 200, part of the air will directly contact the kitchen waste for composting, and the other part of the air will be introduced into the air pipe 300 and contact the kitchen waste inside through the first air holes 301 on the air pipe 300; in this way, the fermentation rate of the kitchen waste is improved.

[0056] Please refer to Figures 1 to 6 In some embodiments, the height of the partition plate 400 along the depth direction D of the barrel body 100 is less than the height of the air pipe 300 along the depth direction D of the barrel body 100.

[0057] It should be understood that the partition plate 400 is used to divide the fermentation bin 101, so that the compost formed by the humus and the kitchen waste is accumulated between the barrel body 100, the air pipe 300 and the adjacent two partition plates 400.

[0058] The height of the partition plate 400 is set to be less than the height of the air pipe 300, and the partition plate 400 and the air pipe 300 are both connected to the inner bottom wall of the barrel body 100; thus, the height of the top plate of the partition plate 400 will be lower than the height of the top of the air pipe 300. In this way, when the fermentation bin 101 is filled with humus and kitchen waste, the humus and kitchen waste are less likely to fall into the inside of the air pipe 300 even if they exceed the height of the partition plate 400, thereby effectively solving the problem of the air pipe 300 being blocked.

[0059] Please refer to Figures 1 to 6 In some embodiments, the barrel body 100 is provided with a water faucet 110, which is located at the bottom of the barrel body 100 and is connected to any fermentation bin 101. One end of the water faucet 110 connected to the fermentation bin 101 is covered with a filter screen cover 120.

[0060] Optionally, the number of water faucets 110 can be one, two or any multiple. For example, in some embodiments, the number of water faucets 110 can be one, and the water faucet 110 can be connected to one of the fermentation bins 101.

[0061] The water faucet 110 is located at the bottom of the barrel body 100; optionally, the water faucet 110 can be specifically arranged at the bottom of the side wall of the barrel body 100; or the water faucet 110 can also be arranged on the bottom wall of the barrel body 100, i.e. at the bottom of the entire barrel body 100.

[0062] At the same time, the end of the water faucet 110 connected to the fermentation bin 101 is covered with a filter screen cover 120, so that when there is leachate in the fermentation bin 101, the leachate can be discharged from the fermentation bin 101 through the water faucet 110, and the filter screen cover 120 can block the passage of larger particles to avoid blocking the water faucet 110.

[0063] In this way, by arranging the water faucet 110 at the bottom of the barrel body 100, the leachate in the fermentation bin 101 can be discharged to avoid affecting the air permeability of the kitchen waste at the bottom of the fermentation bin 101.

[0064] In some embodiments, the filter screen cover 120 can also be arranged at the inner bottom of the fermentation bin 101, and the filter screen cover 120 has a certain distance from the inner bottom wall of the barrel body 100; in this way, the filter screen cover 120 can divide the fermentation bin 101 into two parts, one part near the inner bottom wall of the barrel body 100 is used as a temporary storage area for leachate, and one end of the water faucet 110 can be connected to this part; the other part can be used as a composting area of the fermentation bin 101 to realize composting fermentation operation. In this way, even if only one water faucet 110 is arranged, the leachate in each fermentation bin 101 can be discharged.

[0065] Optionally, the number of filter covers 120 can be set to be consistent with the number of fermentation bins 101, that is, the bottom of each fermentation bin 101 can be provided with the filter cover 120.

[0066] Please refer to Figures 1 to 6 In some embodiments, the bottom of the barrel body 100 is provided with a support structure 130, and the barrel body 100 is supported and placed through the support structure 130.

[0067] Optionally, the support structure 130 includes but is not limited to structures such as feet, support blocks, support frames, etc. The support structure 130 can be fixedly arranged on the side wall of the barrel body 100, or can be fixedly arranged on the bottom wall of the barrel body 100.

[0068] In this way, the barrel body 100 is elevated by the support structure 130, so that the height of the faucet 110 is increased, and thus it is convenient to place a container to take the leachate.

[0069] Please refer to Figures 1 to 6 The surface of the barrel body 100 and the barrel cover 200 is covered with a heat preservation layer (not shown in the figure).

[0070] Optionally, the heat preservation layer includes but is not limited to materials such as polyethylene foam plastic board and polyurethane foaming layer that have heat preservation effect. The heat preservation layer can be fixed and cover the outer surface of the barrel body 100 and the outer surface of the barrel cover 200 by bonding or the like.

[0071] In this way, the heat preservation layer is used to improve the heat preservation effect inside the fermentation bin 101, so that the kitchen waste in the internal compost can maintain a suitable fermentation temperature, thereby promoting the decomposition of the kitchen waste by microorganisms and effectively improving the fermentation rate.

[0072] Please refer to Figures 1 to 6 In some embodiments, the side of the barrel cover 200 facing the barrel body 100 is provided with a sealing ring 220, which is configured to fill the gap between the barrel cover 200 and the barrel body 100 when the barrel cover 200 is covered on the barrel body 100.

[0073] The sealing ring 220 can be a rubber sealing ring 220, a silica gel sealing ring 220, etc. When the barrel cover 200 is covered on the barrel body 100, the sealing ring 220 is clamped between the barrel cover 200 and the barrel body 100, so that the sealing ring 220 can fill the gap between the barrel cover 200 and the barrel body 100, thereby improving the sealing between the barrel cover 200 and the barrel body 100, thereby reducing the probability of mosquitoes entering the fermentation bin 101.

[0074] Please refer to Figures 1 to 6 In some embodiments, the cross section of the barrel body 100 is circular; or the cross section of the barrel body 100 is rectangular.

[0075] When the cross section of the barrel body 100 is circular, the barrel body 100 is a round barrel.

[0076] When the cross section of the barrel body 100 is rectangular, the barrel body 100 is a square barrel. The square barrel body 100 can more effectively utilize the corner space when placed, thereby improving space utilization.

[0077] Below, the multi-bin circulating composting barrel 1000 provided in this application will be further introduced with a specific implementation method.

[0078] Please refer to Figures 1 to 6 In this embodiment, the interior of the barrel 100 is divided into three fermentation chambers 101 by ventilation tubes 300 and three partitions 400. First, a "sandwich composting method" is implemented in the first fermentation chamber 101. This method involves stacking soil and food waste in sequence until the first fermentation chamber 101 is full. The food waste is then allowed to remain stationary and ferment continuously within the first fermentation chamber 101 until it matures into humus. Leachate that seeps out during the composting process needs to be drained out through a tap 110 to prevent it from affecting the air permeability of the food waste at the bottom and hindering fermentation.

[0079] The second fermentation chamber 101 is filled with humus soil, and the third fermentation chamber 101 is left empty.

[0080] After fermentation for a certain period of time, the barrel cover 200 is removed, and the long-handled ladle 500 is taken out from the air vent 300. A layer of humus soil is taken out from the second fermentation bin 101 using the long-handled ladle 500 and spread on the bottom of the third fermentation bin 101. Then, a layer of kitchen waste is added into the third fermentation bin 101. Compost is added back and forth in this way until the third fermentation bin 101 is filled.

[0081] Because the newly added kitchen waste occupies the internal space of the third fermentation bin 101, the humus soil in the second fermentation bin 101 cannot be completely filled into the third fermentation bin 101 and there is a remainder; the remaining humus soil in the second fermentation bin 101 is taken out using a long-handled spoon 500 and used for fertilization or planting, and then the long-handled spoon 500 is put back into the air vent 300 and covered with the barrel lid 200 to prevent rainwater and scavengers from entering.

[0082] After a certain period of fermentation, the barrel cover 200 is removed, and the long-handled ladle 500 is taken out from the air vent 300. The long-handled ladle 500 is used to push away the surface compost in the first fermentation bin 101 to observe whether the kitchen waste inside has been decomposed. If it is completely decomposed and turned into humus soil, the long-handled ladle 500 can be used to take out a layer of humus soil from the first fermentation bin 101 and spread it on the bottom of the second fermentation bin 101. Then, a layer of kitchen waste is added to the second fermentation bin 101. Compost is added back and forth in this way until the second fermentation bin 101 is filled.

[0083] Because the newly added kitchen waste occupies the internal space of the second fermentation bin 101, the humus in the first fermentation bin 101 cannot be completely filled into the second fermentation bin 101, and there is a surplus. The long-handled spoon 500 is used to take out the surplus humus in the first fermentation bin 101 and use it for fertilization or planting, and then the long-handled spoon 500 is put back into the air pipe 300 and the barrel cover 200 is covered to prevent rainwater and carrion animals from entering.

[0084] After a certain period of fermentation, the barrel cover 200 is removed, and the long-handled spoon 500 is taken out of the air pipe 300. The surface compost in the third fermentation bin 101 is stirred with the long-handled spoon 500 to observe whether the internal kitchen waste has rotted. If it has completely rotted into humus, a layer of humus can be taken out of the third fermentation bin 101 with the long-handled spoon 500 and laid flat on the bottom of the first fermentation bin 101, and then a layer of kitchen waste is put into the first fermentation bin 101. In this way, composting is repeated in the first fermentation bin 101 until it is filled.

[0085] Because the newly added kitchen waste occupies the internal space of the first fermentation bin 101, the humus in the third fermentation bin 101 cannot be completely filled into the first fermentation bin 101, and there is a surplus. The long-handled spoon 500 is used to take out the surplus humus in the third fermentation bin 101 and use it for fertilization or planting, and then the long-handled spoon 500 is put back into the air pipe 300 and the barrel cover 200 is covered to prevent rainwater and carrion animals from entering.

[0086] In this way, the internal fermentation bins 101 of the barrel body 100 return to the initial state, and therefore, by repeatedly performing the above steps, three-bin cycle composting can be achieved, effectively improving the composting efficiency.

[0087] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
