Description

Technical Field

[0001] This utility model relates to the field of fermentation composting technology, and in particular to a membrane-covered composting fermentation device. Background Technology

[0002] In the field of modern agriculture and the resource utilization of organic waste, film-coated composting fermentation technology, as an efficient and environmentally friendly method of organic fertilizer production, is being increasingly widely used. This technology effectively regulates the temperature, humidity, and gas exchange environment inside the compost pile by covering the surface of the compost material with a special film, accelerating the microbial decomposition process, improving composting efficiency and product quality, while reducing nutrient loss and harmful gas emissions. This is of great significance for promoting sustainable agricultural development.

[0003] However, the mainstream membrane composting fermentation equipment currently on the market faces a key challenge in its design and application: to prevent leachate (rich in nutrients such as nitrogen and phosphorus, as well as potentially harmful substances) generated during fermentation from directly seeping into the soil and causing land pollution and eutrophication of water bodies, the traditional approach is to harden the composting site, such as by laying concrete or asphalt. While this measure can effectively isolate the leachate, it introduces new problems.

[0004] Agricultural land, as a valuable natural resource, inherently requires maintaining soil permeability and biological activity to facilitate crop growth and ecological balance. Land hardening not only damages soil structure, reduces the living space for soil microorganisms, and affects natural soil fertility and water permeability, but also restricts natural rainwater infiltration, increases surface runoff, and may lead to localized water cycle imbalances. Furthermore, once hardened ground is constructed, subsequent conversion or restoration to agricultural land is costly and complex, negatively impacting the flexibility and sustainability of agricultural production.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0028] The following is combined Figures 1-5 This invention describes a membrane-covered composting fermentation device.

[0029] According to the membrane composting fermentation device proposed in the embodiments of this application, the membrane composting fermentation device includes a flexible impermeable base 201 and a drainage and ventilation device 203. The flexible impermeable base 201 is laid on the ground to support the compost pile 202. The drainage and ventilation device 203 is disposed inside the flexible impermeable base 201. The drainage and ventilation device includes a drainage trough 204 and a ventilation duct 103. The drainage trough 204 is used to collect and discharge leachate, and the ventilation duct 103 is used to transport gas. The ventilation duct 103 is disposed inside the drainage trough 204 to avoid the ventilation duct 103 from shifting position during the air supply process.

[0030] According to the embodiments of this application, the membrane composting fermentation device uses a flexible impermeable base to support the fermentation materials and collect the leachate generated during the fermentation process, replacing the hardened ground. The drainage and ventilation device enables the directional collection and discharge of leachate, and is easy to disassemble, move and assemble. It can effectively prevent leachate from polluting the land, and does not require hardening of agricultural land. Compared with ordinary membrane technology, it has advantages in cost and convenience.

[0031] Understandably, the flexible impermeable base 201 is the foundation of the entire device, laid on the ground. Unlike traditional methods that require hardening the ground to prevent leachate contamination of the soil, the flexible impermeable base 201 is made of a special flexible impermeable material. This material has good flexibility, can adapt to undulations and unevenness of the ground, and eliminates the need for large-scale hardening of agricultural land, thus protecting the natural structure and ecological function of the soil.

[0032] The drainage and ventilation device 203 is installed inside the flexible impermeable base 201. This integrated design makes the entire device more compact, occupies less space, and facilitates installation and maintenance. The drainage and ventilation device 203 mainly consists of a drainage channel 204 and a ventilation duct 103.

[0033] The drainage trough 204 is a structure specifically designed for collecting and draining leachate. The drainage trough 204 can have a certain slope and containment space. During fermentation, the leachate collected on the flexible impermeable base 201 flows into the drainage trough 204 and is then discharged outside the device through the drain outlet on the drainage trough 204. This ensures that the leachate inside the device is treated promptly and effectively, preventing its accumulation and retention within the device, reducing odors and the growth of pathogens, and providing a dry and clean environment for composting fermentation.

[0034] The ventilation duct 103 is responsible for transporting gas, providing the necessary gas exchange conditions for the fermentation process. During composting, the metabolic activities of microorganisms require sufficient oxygen and other gases. The ventilation duct 103 delivers outside air or specific gases into the material, meeting the growth needs of microorganisms, promoting their metabolic activities, and thus accelerating the composting process. Notably, the ventilation duct 103 is located inside the drainage trough 204; this unique design brings significant technical benefits. When gas is discharged from the ventilation duct 103, it creates continuous and intense bubbling and turbulence within the drainage trough 204—a "gas-rush" force—while the drainage trough and cover prevent the ventilation duct from shifting position during air delivery.

[0035] Compared to conventional molecular membrane technology, the membrane-coated composting fermentation device of this application does not require cement hardening of the ground and surrounding area in contact with the materials, resulting in lower costs. Furthermore, the drainage and ventilation device 203 is easy to disassemble, move, and assemble, allowing users to flexibly adjust the location and scale of the device according to actual needs, making it more convenient to use.

[0036] According to one embodiment of this application, a plurality of exhaust holes are arranged alternately at a 45-degree angle above and directly above the ventilation duct 103 for conveying gas to the material.

[0037] According to one embodiment of this application, the drainage trough 204 inside the flexible impermeable base 201 can be spliced ​​from U-shaped prefabricated drainage pipes 207, and a water grate cover plate 205 is placed on top of the drainage trough 204.

[0038] Understandably, the U-shaped prefabricated drainage pipe 207 improves the ease of installation for the drainage channel 204 and the ventilation duct 103. Installers only need to splice and install the U-shaped prefabricated drainage pipe 207, and then bond them together with pipe joint adhesive to form the drainage channel 204. The ventilation duct 103 is then accurately embedded into the drainage channel 204, and a water grate cover plate 205 is placed on top of the drainage channel 204 to complete the installation. This greatly improves the accuracy and efficiency of installation and reduces human error during the installation process. The sidewalls of the drainage channel 204 constrain the ventilation duct 103, preventing horizontal displacement. Simultaneously, the water grate cover plate 205 provides stable support for both the drainage channel 204 and the ventilation duct 103, enhancing their vertical stability.

[0039] According to one embodiment of this application, the flexible seepage-proof substrate 201 is a rubber layer with a thickness of not less than 1 cm, which greatly improves the reliability of seepage prevention.

[0040] According to one embodiment of this application, the flexible impermeable base 201 is provided with a slope for guiding leachate into the collection tank 107.

[0041] The slope of the flexible impermeable substrate 201 in this application cleverly utilizes the effect of gravity. Once leachate is generated, it will flow naturally and smoothly along the slope. This flow pattern is continuous and stable, requiring no additional power, thus greatly reducing energy consumption and equipment costs. At the same time, the slope design allows the leachate to quickly collect in the collection tank 107.

[0042] According to one embodiment of this application, a water collection tank 107 is included, and a drainage channel 204 of a drainage and ventilation device is connected to the water collection tank 107.

[0043] As a large-scale liquid collection and temporary storage facility, the collection tank 107 has a large volume and strong buffering capacity. When the leachate in the drainage trough 204 reaches a certain amount, it will flow smoothly into the collection tank 107 through the pre-laid connecting pipes.

[0044] The connection between the collection tank 107 and the drainage trough 204 facilitates real-time monitoring of the leachate. Water quality monitoring equipment can be installed at the collection tank to monitor important parameters such as pH, chemical oxygen demand, and ammonia nitrogen content of the leachate in real time. Through this monitoring data, technicians can promptly understand the generation and changing trends of leachate during fermentation.

[0045] According to one embodiment of this application, the drainage ventilation device includes a fan 101, which is connected to a ventilation duct 103 and provides airflow to the ventilation duct 103.

[0046] According to one embodiment of this application, the membrane composting fermentation device includes a molecular membrane covering layer, which covers a flexible impermeable base 201, a drainage and ventilation device 203, and a material pile 202 above them.

[0047] In one embodiment, the drainage channel 204 and the ventilation duct 103 are detachable and overlap with the flexible impermeable base 201.

[0048] In one embodiment, a grate cover 205 is included, which covers the drainage channel 204.

[0049] In one embodiment, a rubber sheet is laid on the ground to form a flexible impermeable base 201.

[0050] In one embodiment, the fan 101 is mounted on the ground via a bracket 102.

[0051] In one embodiment, the U-shaped prefabricated drain pipe 207 is connected by a joint adhesive 206.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
