Description

Technical Field

[0001] This utility model relates to the field of greenhouse fermentation technology, and more specifically, to a fermentation and heating device for greenhouse cultivation. Background Technology

[0002] Greenhouse cultivation is a method of improving crop yield and quality through artificial environmental control. However, maintaining suitable temperatures remains a significant challenge in cold seasons or low-temperature regions. Traditional heating methods, such as electric heating and coal-fired boilers, are costly, energy-intensive, and do not align with the development trend of green agriculture. Therefore, some growers are exploring fermentation heating technology, which utilizes microorganisms to decompose organic materials and generate bioheat to provide heat for the greenhouse. This method is low-cost, environmentally friendly, and can improve soil fertility, showing considerable application potential.

[0003] In practical applications, fermentation heating technology requires frequent turning of the fermentation pile to promote uniform fermentation and regular water replenishment to maintain suitable humidity. These operations are not only labor-intensive and time-consuming, but also require a high level of experience from the operators, increasing production costs and management difficulty, and reducing the practicality and economic benefits of the technology.

[0004] In conclusion, to enhance the applicability and promotion value of fermentation heating technology in greenhouse cultivation, it is necessary to address the issues of cumbersome fermentation pile management and high labor costs. This would enable the technology to provide stable heating while reducing labor intensity and management difficulty, thereby truly leveraging its environmental and energy-saving advantages and providing a more efficient solution for the sustainable development of modern agriculture.

[0022] It should be noted that the fermentation tank 2 is located on the side of the wall of the greenhouse body 1. After opening the lid 4, the fermentation material is placed in the fermentation tank 2 for fermentation. When stirring is required, the motor 7 drives the gear 8 to rotate, the gear 8 drives the gear 9 to rotate, and the gear 9 drives the stirring rod 5 and the stirring plate 11 to rotate, stirring the fermentation material to promote fermentation. The heat preservation cabinet 3 plays a role in heat preservation during the fermentation process, and the stirring rod 5 rotates on the support rod 10 at the same time.

[0023] Refer to the instruction manual appendix Figure 5 An oxygen concentrator 12 is fixedly connected to the front end of the insulated cabinet 3, and an oxygen pipe 13 is fixedly connected to the right end of the oxygen concentrator 12.

[0024] It should be noted that the oxygenator 12 inputs oxygen-containing air into the oxygen pipe 13, and the oxygen concentration and flow rate can be adjusted according to the fermentation requirements to ensure that the microbial fermentation process obtains the optimal oxygen content. The oxygen pipe 13 is made of corrosion-resistant flexible material, and the pipe wall is embedded with reinforcing ribs to prevent bending and blockage.

[0025] Refer to the instruction manual appendix Figure 5 Oxygen pipe 13 is fixedly connected to fermentation tank 2 and oxygen pipe 13 is fixedly connected to heat preservation cabinet 3.

[0026] It should be noted that air is introduced into the fermentation tank 2 through the nozzle 14 on the oxygen pipe 13. The nozzle 14 adopts a porous diffusion structure design, which can realize the micronization of bubbles, significantly improve the oxygen mass transfer efficiency, and enable the fermentation material to obtain uniform aeration.

[0027] Refer to the instruction manual appendix Figure 5 Multiple nozzles 14 are installed at the right end of the oxygen pipe 13, and a temperature detector 15 is installed at the left end of the greenhouse body 1.

[0028] It should be noted that temperature detector 15 detects the temperature inside fermentation tank 2. This detector uses a PT100 platinum resistance temperature sensor to monitor the data in real time.

[0029] Refer to the instruction manual appendix Figure 2 A fixed pipe 16 is fixedly connected to the bottom of the fermentation tank 2, and a filter plate 17 is installed inside the fixed pipe 16.

The water inlet is equipped with a protective cover, and water can be added to the fermentation tank 2 through the water inlet.

[0035] Working principle: The fermentation tank 2 is located on the wall of the greenhouse body 1. After opening the lid 4, the fermentation material is placed in the fermentation tank 2 for fermentation. When stirring is required, the motor 7 drives the gear 1 8 to rotate, the gear 1 8 drives the gear 2 9 to rotate, and the gear 2 9 drives the stirring rod 5 and the stirring plate 11 to rotate, stirring the fermentation material and promoting fermentation. At the same time, the stirring rod 5 rotates on the support rod 10. The aerator 12 inputs oxygen-containing air into the oxygen pipe 13. The oxygen concentration and flow rate can be adjusted according to the fermentation requirements to ensure that the microbial fermentation process obtains the optimal oxygen content. The oxygen pipe 13 is made of corrosion-resistant flexible material, and the pipe wall is embedded with reinforcing ribs to prevent bending and blockage. Air is input into the fermentation tank 2 through the nozzle 14 on the oxygen pipe 13. The nozzle 14 adopts a porous diffusion structure design, which can realize the micro-refinement of bubbles and significantly improve the oxygen mass transfer efficiency. The fermentation material is evenly aerated. Temperature detector 15 detects the temperature inside the fermentation tank 2. This detector uses a PT100 platinum resistance temperature sensor to monitor the data in real time. The fermentation liquid in the fermentation tank 2 can be collected by flowing out through the fixed pipe 16. The filter plate 17 can effectively intercept solid fermentation material while ensuring smooth liquid flow. The sealing cover 18 rotates the sealing fixed pipe 16. The cover adopts a double sealing structure of polytetrafluoroethylene sealing ring and silicone gasket to achieve complete locking and prevent gas leakage during fermentation. The high-temperature gas generated by fermentation enters the interior of the greenhouse body 1 through the air outlet pipe 19 and the connecting plate 20 and the hole 21. The hole 21 is arranged in an involute line shape, which can be used with the exhaust fan to evenly diffuse the hot and humid gas to the cultivation area. The water inlet is equipped with a protective cover, and water can be added to the fermentation tank 2 through the water inlet.
