Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, specifically to a composting device that facilitates aerobic composting of solid waste. Background Technology

[0002] Aerobic composting technology, as an environmentally friendly and economical method for treating organic solid waste, has been widely used in recent years. For example, coal gangue is a solid waste. Under conditions of good ventilation and sufficient oxygen, aerobic microorganisms are used to absorb, oxidize, and decompose the waste. Through this process, organic solid waste can be transformed into stable humic substances (organic fertilizer), realizing the resource utilization of waste while reducing environmental pollution.

[0003] Existing aerobic composting equipment technologies generally employ complex component combinations, resulting in high production costs and cumbersome operation. The existing equipment designs do not fully grasp the core principles of aerobic composting, preventing the achievement of functionality through simple and effective components. The equipment is not only expensive to manufacture but also inconvenient for users in practical applications, failing to demonstrate the economic efficiency and practicality that aerobic composting technology should possess. Utility Model Content

[0004] The purpose of this invention is to provide a composting device that facilitates aerobic composting of solid waste, thereby solving the problem of low composting efficiency in existing composting devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composting device for easy aerobic composting of solid waste includes: a plastic bucket, a gas connection valve, a ceramsite hopper, a support ventilation plate, a solid waste trough, a cover plate, an air pump, an air pipe, an air bag, and a guide block.

[0007] A gas connection valve is located on the outer surface of the plastic bucket and connects to the inner cavity of the plastic bucket. A venting plate is located inside the inner cavity of the plastic bucket, dividing the inner cavity into a first inner cavity and a second inner cavity. The plastic bucket has an opening in the second inner cavity. A ceramic pellet hopper is slidably connected to the inner wall of the plastic bucket through the opening and is located in the second inner cavity. A solid waste trough is located in the first inner cavity, and there is a gap between the outer side of the solid waste trough and the inner wall of the plastic bucket. A cover plate is detachably installed on the solid waste trough. An air bag and a guide block are fixed to the inner wall of the plastic bucket from top to bottom and located in the gap. The outer surfaces of the air bag and the guide block are in contact with the solid waste trough. An air pump is located on the outer surface of the plastic bucket and is connected to the air bag through an air pipe.

[0008] In some implementations, it also includes: a monitor, a connecting cable, and a temperature and humidity monitoring probe;

[0009] The monitor is fixed to the outer surface of the plastic bucket, and the temperature and humidity monitoring probe is set on the inner wall of the plastic bucket and located in the gap. The monitor is connected to the temperature and humidity monitoring probe through a connecting wire.

[0010] In some implementations, the plastic bucket has a cuboid structure with a length-to-width-to-height ratio of 1:0.9:2.

[0011] In some implementations, the solid waste trough is a cuboid structure with a length-to-width-to-height ratio of 1.25:1:2.

[0012] In some embodiments, a ventilation groove is formed on the ceramsite hopper, and the opposite side walls of the ventilation groove have recesses, which are located on the outside of the ventilation groove to form a side air groove.

[0013] In some implementations, gas connection valves are located on opposite sides of the plastic drum and connect to side gas channels.

[0014] In some implementations, several flow holes are provided on both the venting plate and the solid waste channel.

[0015] In some implementations, four guide blocks are provided and fixed to the inner wall of the plastic bucket at equal intervals.

[0016] In some embodiments, handles are provided on the outer surfaces of the ceramsite hopper and the cover plate, and a lifting handle is provided on the solid waste trough.

[0017] In some embodiments, a buckle is rotatably connected to the surface of the plastic bucket. When the ceramsite hopper is inside the plastic bucket, one end of the buckle rotates to the surface of the ceramsite hopper for positioning.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention features a gas connection valve positioned on the outer surface of a plastic bucket and connected to its inner cavity. This allows for connection to an external gas pipeline, controlling gas flow during composting. The plastic bucket is inexpensive, lightweight, and durable. A ceramic pellet hopper slides through the opening to the inner wall of the plastic bucket and is positioned within the second inner cavity. A solid waste trough is positioned within the first inner cavity, effectively collecting the products from the solid waste trough during composting. The ceramic pellet hopper can be slidably removed for easy periodic replacement of the ceramic pellets. Gaps exist between the outer side of the solid waste trough and the inner wall of the plastic bucket, providing channels for gas flow along the sides of the compost pile and addressing the problem of oxygen deficiency in the central area of ​​traditional composting systems. A detachable cover is installed on the solid waste trough for convenient placement of solid waste. The airbag and guide block are fixed sequentially from top to bottom to the inner wall of the plastic bucket and located within the gap. The outer surfaces of both the airbag and the guide block contact the solid waste channel. An air pump is located on the outer surface of the plastic bucket and connected to the airbag via an air pipe. When the airbag is inflated, it expands, tightly fitting against the outer wall of the solid waste channel and the inner wall of the plastic bucket, effectively sealing the top of the gap. This prevents air introduced from the gas connection valve from escaping directly from the top gap without fully reacting with the compost, significantly improving oxygen utilization. When the airbag contracts, it relieves pressure on the solid waste channel, allowing for easy removal or insertion of the solid waste channel in conjunction with the guide block. Therefore, this invention can improve composting efficiency while reducing costs.

[0020] Furthermore, the monitor is fixed to the outer surface of the plastic bucket, and the temperature and humidity monitoring probe is set on the inner wall of the plastic bucket and located in the gap. The monitor is connected to the temperature and humidity monitoring probe through a connecting wire, which can directly monitor the temperature and humidity near the compost and provide real-time data.

[0021] Furthermore, a ventilation groove is opened on the ceramsite hopper, and a recess located outside the ventilation groove forms a side air groove, which can enhance bottom ventilation, allowing air introduced from the bottom to pass through the ceramsite layer more easily. The side air groove provides a more direct lateral flow path for the gas.

[0022] Furthermore, the gas connection valves are located on the surfaces of opposite sides of the plastic barrel and connect to the side gas channels, which can improve the efficiency of gas discharge and external air supply.

[0023] Furthermore, four guide blocks are provided and fixed to the inner wall of the plastic bucket at equal intervals to ensure that the solid waste channel remains centered inside the plastic bucket and that the gas flows evenly within the gaps.

[0024] Furthermore, handles are provided on both the ceramsite hopper and the cover plate to facilitate moving the ceramsite hopper and the cover plate, and a lifting handle is provided on the solid waste trough to facilitate removing the solid waste trough.

[0025] Furthermore, the plastic bucket has a rotating connecting buckle. When the ceramsite hopper is inside the plastic bucket, one end of the buckle rotates to the surface of the ceramsite hopper for limiting, which can effectively prevent the ceramsite hopper from accidentally slipping out during use and ensure the airtightness of the ceramsite hopper.

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

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides a composting device for easy aerobic composting of solid waste, including: a plastic bucket 1, a gas connection valve 2, a ceramic pellet hopper 3, a bearing ventilation plate 4, a solid waste channel 5, a cover plate 6, an air pump 7, an air pipe 8, an air bag 9, and a guide block 13.

[0037] The plastic bucket 1 has a rectangular structure with a length-to-width-to-height ratio of 1:0.9:2. The inner cavity of the plastic bucket 1 is divided into an upper first inner cavity and a lower second inner cavity by a supporting venting plate 4. The supporting venting plate 4 is provided with several flow holes, which facilitate the flow of gas between the first and second inner cavities and promote gas exchange during the composting process.

[0038] The plastic bucket 1 has an opening in the second inner cavity, which is used for sliding connection with the ceramsite hopper 3. The ceramsite hopper 3 is slidably connected to the inner wall of the plastic bucket 1 through this opening and is located in the second inner cavity. The ceramsite hopper 3 has a ventilation groove 3-2, and there are recesses on the opposite side walls of the ventilation groove 3-2. These recesses are located on the outside of the ventilation groove 3-2, forming a side air groove 3-1. The side air groove 3-1 and the ventilation groove 3-2 can increase the gas flow path, so that oxygen is more evenly distributed in the composting environment, enhance the activity of aerobic microorganisms, and accelerate the composting process. The outer surface of the ceramsite hopper 3 is provided with a handle, which makes it easy for the operator to pull out or push the ceramsite hopper 3 in.

[0039] Gas connection valves 2 are installed on opposite sides of the plastic bucket 1 and connected to side air channels 3-1. The installation of gas connection valves 2 allows outside air to enter the plastic bucket 1, providing oxygen for the composting process, while also allowing the exhaust of gases generated during composting.

[0040] The solid waste trough 5 is a container for holding solid waste such as coal gangue, facilitating the placement and processing of composting materials. The solid waste trough 5 is located within the first inner cavity, supported by a venting plate 4. The solid waste trough 5 has a rectangular structure with a length-to-width-to-height ratio of 1.25:1:2. Gaps exist between the outer sides of the solid waste trough 5 and the inner wall of the plastic bucket 1. Several flow holes are provided on the solid waste trough 5 to facilitate gas circulation inside and outside the trough 5, promoting gas exchange during the composting process.

[0041] The cover plate 6 is detachably installed on the solid waste trough 5 to prevent odors from escaping and debris from falling in during composting. It also facilitates the addition or stirring of raw materials by opening the cover plate 6. A handle is provided on the outer surface of the cover plate 6 for easy removal or installation by operators. The cover plate prevents odors from escaping during composting and also helps maintain the moisture content of the compost material.

[0042] The airbag 9 and guide block 13 are fixed sequentially from top to bottom to the inner wall of the plastic bucket 1 and located within the gap. The outer surfaces of both the airbag 9 and guide block 13 are in contact with the solid waste trough 5. Figure 4 As shown, four guide blocks 13 are provided, and each guide block 13 is fixed to the inner wall of the plastic bucket 1. The guide blocks 13 are provided to guide and limit the movement of the solid waste trough 5, ensuring that the solid waste trough 5 slides smoothly during the lifting and lowering process, and avoiding deviation or jamming.

[0043] An air pump 7 is located on the outer surface of the plastic bucket 1 and is connected to an air bladder 9 via an air pipe 8. The function of the air pump 7 is to inflate or depress the air bladder 9. By controlling the expansion or contraction of the air bladder 9, when the air bladder 9 is inflated, it can tightly fit against the outer wall of the solid waste channel 5 and the inner wall of the plastic bucket 1, effectively sealing the top of the gap and preventing air introduced from the gas connection valve 2 from escaping directly from the top gap without fully reacting with the stockpile. This can significantly improve oxygen utilization. When the air bladder 9 deflates and contracts, it can relieve the pressure on the solid waste channel 5. At this time, it can be used in conjunction with the guide block 13 to remove or place solid waste into the solid waste channel 5.

[0044] A buckle 14 is rotatably connected to the surface of the plastic bucket 1. When the ceramsite hopper 3 is inside the plastic bucket 1, one end of the buckle can rotate to the surface of the ceramsite hopper 3 for limiting, preventing the ceramsite hopper 3 from accidentally slipping out during use. A cover handle 16 is provided on the surface of the cover plate 6, a ceramsite hopper handle 17 is provided on the surface of the ceramsite hopper 3, and a handle 15 is provided on the solid waste trough 5.

[0045] The composting device provided in this embodiment also includes a monitor 10, a connecting cable 11, and a temperature and humidity monitoring probe 12. The monitor 10 is fixed to the outer surface of the plastic bucket 1, and the temperature and humidity monitoring probe 12 is disposed on the inner wall of the plastic bucket 1 and located within a gap. The monitor 10 is connected to the temperature and humidity monitoring probe 12 via the connecting cable. The temperature and humidity monitoring probe 12 can monitor the temperature and humidity changes during the composting process in real time, and the monitor 10 can display this data, making it easier for operators to understand the composting status and environment, adjust composting parameters in a timely manner, and ensure the composting effect.

[0046] The composting device in this embodiment is used as follows: First, rotate the buckle to a position that does not affect the sliding of the ceramsite hopper 3, and then pull the ceramsite hopper 3 out from the opening of the plastic bucket. Next, open the cover plate 6 on the solid waste trough 5, put the solid waste to be composted into the solid waste trough 5, and then close the cover plate 6. After filling the ceramsite hopper 3 with ceramsite or other breathable media, push the ceramsite hopper 3 into the second inner cavity of the plastic bucket 1, and rotate the buckle to limit its position on the surface of the ceramsite hopper 3.

[0047] During composting, solid waste undergoes aerobic decomposition within the solid waste trough 5. Gas connection valve 2 connects to an external gas pipeline, controlling the gas flow during composting and ensuring a stable aerobic environment. External air enters the plastic bucket 1 through gas connection valve 2 on one side, providing oxygen for the composting process. Gases generated during composting can circulate through flow holes and gaps, ultimately exiting through gas connection valve 2 on the other side of the plastic bucket 1.

[0048] By inflating or deflating the airbag 9 using the air pump 7, the solid waste trough 5 can be raised or lowered, facilitating adjustments to the composting position or material mixing. The temperature and humidity monitoring probe 12 monitors temperature and humidity changes in real time during the composting process, and the monitoring instrument 10 displays this data, allowing operators to understand the composting status and make corresponding adjustments.

[0049] Once composting is complete, open the latch, pull out the expanded clay hopper 3, and then remove the composted product from the solid waste trough 5. The expanded clay pebbles in the expanded clay hopper 3 can absorb the odors generated during the composting process, reducing environmental pollution.

[0050] The composting device in this embodiment has a simple structure and is easy to operate. It can effectively promote aerobic composting of solid waste, improve composting efficiency, and reduce environmental pollution. By adjusting the expansion or contraction of the air bladder, the lifting and lowering of the solid waste trough 5 can be controlled, facilitating the adjustment of the composting position or the mixing of materials to meet the needs of different composting materials. The temperature and humidity monitoring system makes the composting process more controllable and ensures better compost quality.

[0051] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All changes within the scope of this utility model or equivalent to this utility model are included in this utility model.
