Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilizer production technology, and in particular to a modular zero-energy oxygen-supplying bioreactor device. Background Technology

[0002] Aerobic fermentation boasts advantages such as rapid reaction speed, high product quality, energy efficiency, environmental friendliness, and ease of control, making it one of the preferred technologies for treating agricultural organic waste, livestock and poultry manure, and municipal solid waste. Utilizing livestock and poultry manure, municipal solid waste, and agricultural organic waste to produce organic fertilizer or substrate through fermentation is an effective way to improve soil fertility, protect the environment, achieve nutrient cycling, and promote sustainable development. Among these factors, oxygen supply is one of the key factors affecting the effectiveness of aerobic fermentation.

[0003] Natural ventilation, mechanical stirring, and forced ventilation are the commonly used oxygen supply methods in aerobic fermentation composting. Natural ventilation is low-cost and simple to operate, but traditional natural ventilation provides uneven oxygen supply, is environmentally unfriendly, and has a long composting cycle, making it suitable for small-scale operations where composting time requirements are not high. Mechanical stirring and forced ventilation, on the other hand, have disadvantages such as large footprint, high initial investment and operating costs, high energy consumption, and complex operation.

[0004] Given the general lack of organic matter in arable land, although the use of organic fertilizers can significantly improve soil structure, provide comprehensive nutrition for crops, and significantly enhance the quality of agricultural products, the production and sale of organic fertilizers are difficult due to high production and transportation costs and unclear economic benefits, thus creating a bottleneck for the large-scale promotion and application of organic fertilizers.

[0005] Therefore, improving the current organic fertilizer production process and reducing production and transportation costs are effective countermeasures to overcome the current difficulties in the large-scale promotion and application of organic fertilizer. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model discloses a modular zero-energy oxygen-supplying bioreactor device, comprising multiple sets of compost materials, breathable packaging bags, a three-dimensional composite breathable mesh, Velcro, an oxygen supply component, a supplementary air supply pipe, a blower, a temperature sensor, a humidity sensor, an oxygen sensor, a pH sensor, a small weather station, a wind-solar hybrid power generation module, and a fermentation control module. The multiple sets of compost materials are respectively filled inside the breathable packaging bags and stacked in a matrix. The three-dimensional composite breathable mesh is fixed to the outside of the breathable packaging bags by Velcro. The oxygen supply component is positioned between adjacent breathable packaging bags. The temperature sensor, humidity sensor, oxygen sensor, and pH sensor are all installed in the compost material. The supplementary air supply pipe is installed in the ground groove at the bottom of the reactor device. The blower is connected to the supplementary air supply pipe. The fermentation control module is electrically connected to the temperature sensor, humidity sensor, oxygen sensor, pH sensor, blower, small weather station, and wind-solar hybrid power generation module. The oxygen supply component includes a ventilation pipe and a wind cap. The ventilation pipe is vertically installed between the compost materials and extends to the outside at the top. The wind cap is installed at the top of the ventilation pipe. Several ventilation holes are provided on the outer wall of the ventilation pipe.

[0007] Furthermore, an electric air valve is provided between the air cap and the ventilation pipe, and the electric air valve is electrically connected to the fermentation control module.

[0008] Furthermore, the three-dimensional composite breathable net includes a core and geotextiles disposed on both sides of the core. The geotextiles have a mesh size of 20-60 mesh. The middle layer of the core consists of multiple parallel rigid ribs, and the upper and lower layers of the core are mesh support structures that intersect with the rigid ribs.

[0009] Furthermore, the surface of the breathable packaging bag is provided with a number of breathable holes, the size of which is 20-60 mesh.

[0010] Furthermore, the outer wall of the ventilation duct is provided with multiple sets of protrusions spaced along the axial direction, and each set of protrusions is arranged around the ventilation duct at intervals.

[0011] Furthermore, the wind-solar hybrid power generation module includes a solar panel, a wind turbine, an inverter control unit, and a battery. The solar panel and the wind turbine are electrically connected to the battery through the inverter control unit, and the inverter control unit and the battery are electrically connected to the fermentation control module.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] I. This utility model packs composting materials into breathable packaging bags to form composting units. The composting units are separated by a three-dimensional composite breathable mesh, which ensures the uniformity, breathability and structural stability of the composting materials, accelerates the fermentation speed and improves the yield and quality of compost.

[0014] Second, the composting unit is easy to store and transport, and there is no need for fermentation tanks, factories and greenhouses during the composting process, which reduces the one-time investment in composting production;

[0015] Third, the composting unit adopts a modular design, which can flexibly control the scale of composting. Composting production can be transferred to the field, shortening the transportation distance and reducing the operation and transportation costs of composting production.

[0016] Fourth, under favorable wind conditions, the air can circulate inside and outside the reactor through the wind cap under the combined effect of natural wind and thermal pressure. Combined with the use of electric air valves, it is possible to achieve zero-energy oxygen supply and precise control of oxygen supply to the reactor.

[0017] Fifth, in the case of poor wind conditions, the use of wind-solar hybrid power generation modules for power supply can ensure the stable operation of the reactor under different weather conditions, reduce the risk of energy supply interruption, and achieve zero energy consumption without the need for additional energy consumption. It has the advantages of energy saving and environmental protection, low maintenance cost and strong adaptability.

[0018] VI. By using multiple sensors and a small weather station connected to the fermentation control module, parameters such as temperature, humidity, and oxygen content during the fermentation process can be monitored in real time. Based on the analysis results of the monitoring data, the fermentation parameters can be adjusted in real time using the temperature, humidity, and gas regulation systems to achieve the effects of reducing costs, improving efficiency, and ensuring quality.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1 As shown, the modular zero-energy oxygen-supplying bioreactor device in this embodiment includes multiple sets of compost materials 1, breathable packaging bags 2, three-dimensional composite breathable nets 3, Velcro 4, oxygen supply components 5, supplementary air supply pipes 6, fans 7, temperature sensors 8, humidity sensors 9, oxygen sensors 10, pH sensors 11, small weather stations 12, wind-solar hybrid power generation modules 13, and fermentation control modules 14.

[0031] Multiple sets of compost materials 1 are stacked in a matrix manner. Oxygen supply components 5 are set between adjacent compost materials 1. Supplementary air supply pipes 6 are set in the ground groove at the bottom of the reactor device. Fans 7 are connected to supplementary air supply pipes 6. Through the setting of oxygen supply components 5 and supplementary air supply pipes 6, the reactor can be ventilated and oxygenated.

[0032] Temperature sensor 8, humidity sensor 9, oxygen sensor 10, and pH sensor 11 are all installed in compost material 1 and electrically connected to fermentation control module 14. By connecting the above sensors to fermentation control module 14, parameters such as temperature, humidity, and oxygen content during the fermentation process can be monitored in real time. Based on the analysis results of the monitoring data, the fermentation parameters can be adjusted in real time using temperature, humidity, and gas control systems to achieve the effects of reducing costs, improving efficiency, and ensuring quality.

[0033] The wind turbine 7, the small weather station 12, and the wind-solar hybrid power generation module 13 are electrically connected to the fermentation control module 14. The wind turbine 7 can supplement the air supply to the reactor. The small weather station 12 can monitor meteorological parameters such as wind speed, wind direction, temperature, humidity, and air pressure and feed them back to the fermentation control module 14. The wind-solar hybrid power generation module 13 can supply power to the entire system.

[0034] Among them, the small weather station 12 can be the FT-CQX5 series small weather station currently available on the market. This weather station is a highly integrated, low-power, quick-installable, and convenient high-precision automatic weather observation device for field use.

[0035] The wind-solar hybrid power generation module 13 includes a solar panel 131, a wind turbine 132, an inverter control unit 133, and a battery 134. The solar panel 131 and the wind turbine 132 are electrically connected to the battery 134 through the inverter control unit 133, and the inverter control unit 133 and the battery 134 are electrically connected to the fermentation control module 14.

[0036] The solar panel 131 and the wind turbine 132 can generate electricity using solar and wind power respectively, achieving energy complementarity. Excess electrical energy is stored in the battery 134 for backup, which can ensure the stable operation of the reactor under different weather conditions, reduce the risk of energy supply interruption, and achieve zero energy consumption without additional energy consumption. It has the advantages of energy saving and environmental protection, low maintenance cost and strong adaptability.

[0037] Among them, temperature sensor 8, humidity sensor 9, oxygen sensor 10 and pH sensor 11 are all probe-type sensors with long probes, which are easy to insert into the compost material 1 to collect parameters such as temperature, humidity, dissolved oxygen and pH value in real time, and convert the above parameters into electrical signals and transmit them to fermentation control module 14. Fermentation control module 14 can adopt the JN-DCS100 aerobic composting fermentation process intelligent control system. Fermentation control module 14 analyzes and processes the collected parameters, and controls the air intake by controlling the valve opening angle of electric air valve 55, thereby optimizing the oxygen supply during the fermentation process.

[0038] If the oxygen supply is sufficient, the activity of aerobic microorganisms will be enhanced, organic matter will decompose rapidly and release heat, and nitrogenous substances will be decomposed more quickly. NH3 will be released to neutralize acidic substances, causing the pH value to rise to neutral or slightly alkaline (7.0-8.0), which is conducive to the activity of thermophilic bacteria. If the oxygen supply is insufficient, the activity of aerobic microorganisms will decrease, the heat production efficiency will also decrease, sugars will decompose to produce organic acids (such as lactic acid and acetic acid), and the pH value will drop to 5.0-6.0.

[0039] In addition, during the ventilation and oxygen supply process, the airflow will carry away some of the moisture in the compost pile, thereby regulating the moisture content in the compost.

[0040] By allowing oxygen supply to interact with temperature, humidity, and pH, multi-parameter synergistic optimization can be achieved during the aerobic fermentation process of composting, thereby ensuring the quality of compost production.

[0041] By employing multiple sensors connected to the fermentation control module 14, parameters such as temperature, humidity, and oxygen content during the fermentation process can be monitored in real time. Based on the analysis of the monitoring data, the fermentation parameters can be adjusted in real time using temperature, humidity, and gas control systems, thereby reducing costs, improving efficiency, and ensuring quality.

[0042] like Figure 2 As shown, compost material 1 is filled into a breathable packaging bag 2. The surface of the breathable packaging bag 2 has several ventilation holes 21 to achieve a ventilation effect and ensure aerobic fermentation of the compost material 1. The three-dimensional composite breathable mesh 3 is fixed to each side wall of the breathable packaging bag 2 by Velcro 4. On the one hand, it reinforces and stabilizes the compost material 1. On the other hand, the three-dimensional skeleton structure can also prevent it from being compacted under the high pressure of stacking multiple compost units, thereby ensuring the ventilation effect between layers.

[0043] like Figure 3 As shown, the three-dimensional composite breathable net 3 includes a core and geotextile 31 arranged on both sides of the core. The middle layer of the core is a series of parallel rigid ribs 32, and the upper and lower layers of the core are mesh support structures 33 that intersect with the rigid ribs 32. The core can be injection molded from HDPE material, and the geotextile 31 is fixed to the upper and lower sides of the core by bonding or hot pressing.

[0044] Geotextile 31 has the characteristics of being breathable and permeable to water, which can ensure the air permeability of compost material 1; HDPE material has a lower density than water, so it is lighter and will not add extra burden to the handling of compost material 1, and has strong resistance to acid and alkali corrosion, which can cope with the acid and alkali environment in the subsequent fermentation process.

[0045] By packing compost material 1 into breathable packaging bags 2 to form composting units, and using three-dimensional composite breathable mesh 3 to separate the composting units, the uniformity, breathability and structural stability of the compost material are ensured, the fermentation speed is accelerated and the yield and quality of compost are improved.

[0046] Modular composting units facilitate storage and transportation, allow for flexible control of composting scale, and enable composting production to be transferred to fields, shortening transportation distances and reducing operating and transportation costs. Furthermore, the composting process eliminates the need for fermentation tanks, factories, and greenhouses, reducing the one-time investment in composting production.

[0047] like Figure 4 As shown, the oxygen supply component 5 includes a ventilation pipe 51 and a vent 52. The ventilation pipe 51 is vertically arranged between the compost materials 1 and extends to the outside at the top. The vent 52 is arranged at the top of the ventilation pipe 51. Several ventilation holes 53 are provided on the outer wall of the ventilation pipe 51. Multiple sets of protrusions 54 are provided on the outer wall of the ventilation pipe 51 at intervals along the axial direction. Each set of protrusions 54 is arranged at intervals around the ventilation pipe 51.

[0048] The protrusion 54 can provide support for the ventilation duct 51, preventing the outer wall of the breathable packaging bag 2 from being directly squeezed onto the outer wall of the ventilation duct 51, which would cause the ventilation holes 21 and 53 to be blocked, thus affecting the oxygen supply effect.

[0049] An electric air valve 55 is installed between the air cap 52 and the ventilation pipe 51, and the electric air valve 55 is electrically connected to the fermentation control module 14. The system prioritizes the use of the air cap 52 for passive oxygen supply. When the oxygen supply from the air cap 52 is insufficient, the blower 7 is started to supplement the oxygen supply.

[0050] The wind cap 52 is a non-powered device that uses natural wind power and thermal pressure effect for ventilation. It mainly consists of a shell, blades, bearings and other components. When the outside natural wind passes through the wind cap 52, the blades rotate under the action of horizontal wind force, thereby driving the internal air to flow from bottom to top, so as to achieve ventilation.

[0051] During fermentation, microbial activity causes the temperature inside the reactor to rise to 50-80℃, with a temperature difference of 30-90℃ between the inside and outside of the reactor. The thermal pressure effect causes hot air to rise due to its decreased density and be discharged through the gaps in the blades of the vent cap 52. At the same time, external cold air replenishes from the bottom, forming a circulation. This process is mainly driven by the thermal pressure difference. Under favorable wind conditions, the combined effect of natural wind and thermal pressure, along with the use of the electric air valve 55, enables zero-energy oxygen supply to the reactor and precise control of the oxygen supply quantity.

[0052] like Figure 5 As shown, the outer wall of the supplementary air supply pipe 6 is provided with several air supply holes 61 to provide supplementary ventilation and oxygen supply to the reactor.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
