The sensor 6 feeds back the monitored parameters such as the temperature, humidity and oxygen content in the fermented material pile body to the control box 105. The intelligent control system in the control box 105 adopts one or more linkage control of the three control methods of temperature, oxygen content and duty cycle according to the set aeration parameters of different temperature periods such as the heating period, high temperature period and cooling period. After the fermentation pile body meets the set aeration parameter value conditions, the blower 102 and the heater 104 are automatically started and stopped, and then the oxygen content, moisture content, temperature and other parameters of the fermentation pile body are adjusted to achieve normal fermentation of the fermentation pile body.

[0049] The working principle of the utility model is as follows: loosen the sealing component 8, uncover the film 7 and pile the fermented material on the upper pressure plate 905 of the ventilation and filtering component 8, arrange the shape of the pile of the fermented material, cover the film 7 on the pile of the fermented material, use the sealing component 8 to seal the film 7 and the fermentation chassis 3 on all sides, turn on the manual mode of the control box 105, adjust the opening and closing angle of the electric air valve 403 according to the size of the pile, ensure that the ventilation volume of the fermented pile is appropriate, check whether there is air leakage in the fermentation body, turn on the automatic mode of the control box 105 after the inspection, set the aeration parameters for different temperature periods, and automatically complete the full-cycle fermentation of the pile of the fermented material through the intelligent control system in the control box 105 according to the parameter value fed back by the sensor 6.

[0050] The utility model aims at the problems existing in the application of traditional nano-membrane covered high-temperature fermentation devices in some small and medium-sized breeding parks, such as large basic investment, inconvenient movement, and the waste generated in a single park cannot meet the fermentation consumption. The utility model makes innovative improvements, optimizes the design of the pre-buried ventilation pipe system and the construction of the leachate discharge system that need to be completed through infrastructure construction, and arranges the ventilation pipes, anti-seepage components, ventilation and filtration components, etc. on the fermentation chassis to form a fermentation main body together with the fermentation chassis, which can be moved with the fermentation chassis. The leachate generated during the fermentation of the fermentation pile is directly collected by the leachate collection box in the anti-seepage combination. The integrated optimized design of the ventilation pipes, anti-seepage components, ventilation and filtration components and the fermentation chassis makes the whole device compact and reduces the manufacturing and application cost of the equipment. Taking into account the seasonality of the generation of different agricultural wastes and the convenient mobility, the device can be shared and used in some medium and small breeding areas, thereby improving the utilization rate of the device and reducing the equipment procurement cost. At the same time, the small size can also be directly placed in a greenhouse to meet the composting treatment needs of agricultural waste generated during the greenhouse planting process.

[0051] When the technology of the utility model is actually applied to the greenhouse for optimization design, the coating is preferably ePTFE nanofilm, the heater is preferably duct heating, the blower is preferably a vortex air pump high-pressure blower, the breathable pad is preferably a coconut silk blanket, the pipe fittings of the ventilation duct are preferably HDPE round tubes, the sensors are digital display temperature probe (BRET-T2000-P), BRET-O500-P digital display oxygen concentration probe, BRET-H600-P soil moisture sensor, the air exhausted by the blower is rapidly heated to about 60°C after passing through the duct heater to meet the fermentation temperature requirement, the first hose between the blower and the heater is a high temperature resistant pipe fixedly connected to the round tubes at the blower outlet and the heater inlet through a throat clamp, the second hose between the heater and the main air inlet pipe of the ventilation duct is a high temperature resistant pipe fixedly connected to the heater outlet round tube and the main air inlet pipe of the ventilation duct through a throat clamp, the pipe fittings will not be deformed after the heated air passes through the high temperature resistant pipe, and is suitable for long-term use.

[0052] The prototype developed in the application embodiment of the utility model has been tested for composting in a fruit and vegetable professional cooperative. The prototype is mainly designed for greenhouse dimensions. The fermentation chassis is 2 meters wide and 4 meters long. In order to verify the effect of the pipeline heater, the test is carried out in the north from November to December, and the outside temperature is about 0-10°C. The raw materials are a mixture of pepper stalks, corn stalks and fungus residues. After the pepper stalks and corn stalks are crushed to about 1 cm by a crusher, the pepper stalks, corn stalks and fungus residues are mixed in a ratio of 2:4:3, and biogas slurry is added as a bacterial agent while adjusting the moisture content of the fermented product. After adjustment, the moisture content is about 70%. The mixed raw materials to be fermented, about 400 kg, are piled on the fermentation chassis of the movable nano-membrane high-temperature fermentation prototype. The fermentation pile is built in a trapezoidal shape, and the nano-membrane cover is set on the pile, and the surroundings are sealed with sealing components.

[0053] The entire fermentation lasted for 32 days. The initial temperature of the pile was 35°C. After 13 hours, the temperature of each measuring point of the pile reached above 55°C and entered the high temperature period. The high temperature period lasted for more than 15 days, with the highest temperature above 70°C and lasting for more than 24 hours. The fermentation device heated up quickly and the high temperature lasted for a long time during the test, which was conducive to the elimination of residual harmful substances in agricultural waste and was not affected by changes in the external environment. There was basically no odor and leachate escaping during the film-covered fermentation process, which can effectively reduce environmental pollution.

[0054] The total nutrients N, P, K and organic matter content of the compost product after fermentation were tested, and seed germination tests were carried out at the same time. The total nutrient mass fraction of N, P, K (on a drying basis) was 8.59%, the mass fraction of organic matter (on a drying basis) was 31.4%, and the seed germination index (GI) was 75%, meeting the relevant index requirements in "Organic Fertilizer NY / T525-2021". After the fermentation test, the same effect as the existing nano-membrane high-temperature fermentation device can be achieved. The prototype developed after the application of the utility model has the advantages of compact structure, small size, and flexible mobility, which can fill the deficiencies of the existing technology and is suitable for promotion and application in some medium and small breeding parks.

Any modification, equivalent substitution and improvement made by any technician familiar with the technical field within the technical scope disclosed by the present invention and within the spirit and principle of the present invention shall be covered by the protection scope of the present invention.
