Description

Technical Field

[0001] The present invention relates to the technical field of grain storage, and in particular to a three-in-one intelligent temperature-controlled grain storage system. Background Art

[0002] Maintaining grain quality and extending its shelf life are crucial during grain storage. However, traditional grain storage methods and technologies face a series of challenges that directly impact safe storage and quality maintenance. Specifically, traditional grain storage methods use a blanket covering the grain pile to minimize environmental impacts on grain quality. However, this method struggles to precisely control the temperature and humidity between the film and the grain surface, leading to a "hot skin, cold core" phenomenon: higher surface temperatures and lower interior temperatures. This not only affects overall grain quality but also poses risks of insect infestation and mildew, making it difficult to maintain stable temperature control year-round, especially during hot seasons. Furthermore, to ensure grain safety, the blanket covering often requires regular removal for ventilation. This process not only increases the workload of custodians but also easily allows moisture to enter, impacting grain quality. In the cold, dry winter environment, ventilation often reduces grain pile temperature but also results in significant moisture loss, negatively impacting grain quality, such as cracking and drying. Controlled atmosphere (CA) technology can significantly improve storage conditions, but existing systems fail to address the challenge of simultaneously regulating the grain pile temperature during CA, limiting its application. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a three-in-one intelligent temperature-controlled grain storage system that can effectively control the temperature, humidity and gas composition of the grain pile.

[0004] According to the present invention, a three-in-one intelligent temperature-controlled grain storage system includes a grain silo unit, a temperature control unit, an air conditioning unit and a control unit. The grain silo unit includes a silo body, a grain pile and a pressure-covering film arranged above the grain pile. A closed first space is formed between the silo body and the pressure-covering film, and a closed second space is formed between the grain pile and the pressure-covering film; the temperature-control unit includes an air-conditioning device, a main air pipe, a first air outlet pipe arranged at the grain pile, a second air outlet pipe arranged at the first space and a third air outlet pipe arranged at the second space. The air inlet end of the main air pipe is connected to the air-conditioning device, and the first air outlet pipe, the second air outlet pipe and the third air outlet pipe are connected to the air-conditioning device. The air inlet ends of the air outlet pipes are all connected to the air outlet ends of the main air pipe, and the first air outlet pipe, the second air outlet pipe and the third air outlet pipe are all provided with air outlet valves; the air conditioning unit includes an air-charging unit, an air supply pipe and a mixing air pipe arranged in the grain pile, the air inlet end of the mixing air pipe is connected to the air outlet end of the first air outlet pipe, and the air outlet end of the mixing air pipe is provided with a main air valve, the air inlet end of the air supply pipe is connected to the air-charging unit, the air outlet end of the air supply pipe is connected to the mixing air pipe, and the air supply pipe is provided with a comprehensive air conditioning valve; the air-conditioning device, the air outlet valve, the air-charging unit, the main air valve and the comprehensive air conditioning valve are all connected to the control unit.

[0005] The three-in-one intelligent temperature-controlled grain storage system according to the embodiment of the present invention has at least the following beneficial effects: The three-in-one intelligent temperature-controlled grain storage system provided by the embodiment of the present invention uses an air-conditioning device to simultaneously independently adjust the temperature and humidity of the grain pile, the space between the warehouse body and the pressure-covering film, and the space between the grain pile and the pressure-covering film, and controls the temperature and humidity through independent air outlet valves. It can accurately deliver the hot and cold air generated by the air-conditioning device to the area where the temperature needs to be adjusted, effectively solving the "hot skin and cold core" problem and ensuring a consistent temperature and humidity environment inside and outside the grain pile. In addition, while adjusting the temperature and humidity of the grain pile, the gas produced by the inflation and gasification unit is delivered to the mixing pipe through the air supply pipe, so that the hot and cold air produced by the air-conditioning device is mixed with the gas produced by the inflation and gasification unit and delivered to the grain pile, thereby performing gas control while controlling the temperature of the grain pile. Under the control of the control unit, the outlet valve of the first outlet pipe, the main gas valve of the mixing pipe, and the integrated gas control valve of the gas supply pipe cooperate with each other to achieve precise control of temperature control and gas control under different conditions. By precisely controlling temperature and gas composition, not only can the growth of pests and mold reproduction be inhibited, but the quality degradation of grain caused by temperature changes during storage can also be reduced, which helps maintain the freshness and nutritional value of grain and extend its storage period.

This design not only improves the system's flexibility and adaptability, but also makes operation simpler and more efficient, reducing the inconvenience and extra workload associated with frequent film removal and ventilation in traditional methods. The ability to ventilate the grain without removing the film throughout the entire cycle significantly reduces the custodian's workload, while also preventing the impact of external moisture or dry air on grain quality, particularly in winter, by preventing excessive water loss.

The grain silo unit includes a silo body 100, a grain pile 110 and a pressure-covering film 120 arranged above the grain pile 110. A sealed first space 130 is formed between the silo body 100 and the pressure-covering film 120, and a sealed second space 140 is formed between the grain pile 110 and the pressure-covering film 120; the temperature-control unit includes an air-conditioning device 200, a main air pipe 210, a first air outlet pipe 220 arranged on the grain pile 110, a second air outlet pipe 230 arranged in the first space 130 and a third air outlet pipe 240 arranged in the second space 140. The air inlet end of the main air pipe 210 is connected to the air-conditioning device 200, the first air outlet pipe 220, the second air outlet pipe 230 and The air inlet end of the third air outlet pipe 240 is connected to the air outlet end of the main air pipe 210, and the first air outlet pipe 220, the second air outlet pipe 230 and the third air outlet pipe 240 are all provided with an air outlet valve 250; the air conditioning unit includes an air-charging unit 300, an air supply pipe 310 and a mixing pipe 320 arranged on the grain pile 110, the air inlet end of the mixing pipe 320 is connected to the air outlet end of the first air outlet pipe 220, the air outlet end of the mixing pipe 320 is provided with a main air valve 321, the air inlet end of the air supply pipe 310 is connected to the air-charging unit 300, the air outlet end of the air supply pipe 310 is connected to the mixing pipe 320, and the air supply pipe 310 is provided with a comprehensive air conditioning valve 311; the air conditioning device 200, the air outlet valve 250, the air-charging unit 300, the main air valve 321 and the comprehensive air conditioning valve 311 are all connected to the control unit.

[0024] It can be understood that the three-in-one intelligent temperature-controlled grain storage system provided by the embodiment of the present invention uses the air-conditioning device 200 to independently adjust the temperature and humidity of the grain pile 110, between the warehouse body 100 and the pressure covering film 120, and between the grain pile 110 and the pressure covering film 120 at the same time, and is regulated by independent air outlet valves 250. The hot and cold air generated by the air-conditioning device 200 can be accurately delivered to the area where the temperature needs to be adjusted, effectively solving the "hot skin and cold core" problem and ensuring a consistent temperature and humidity environment inside and outside the grain pile 110. While regulating the temperature and humidity of grain pile 110, the gas produced by the aeration unit 300 is delivered to the mixing pipe 320 via the air supply pipe 310. The hot and cold air generated by the air conditioning unit 200 is mixed with the gas produced by the aeration unit 300 and delivered to the grain pile 110. This allows for simultaneous temperature control and atmospheric conditioning of the grain pile 110. Under the control of the control unit, the outlet valve 250 of the first outlet pipe 220, the main air valve 321 of the mixing pipe 320, and the integrated atmospheric control valve 311 of the air supply pipe 310 coordinate with each other to achieve precise control of temperature and atmospheric conditioning under different conditions. Precise control of temperature and gas composition not only inhibits the growth of pests and mold, but also reduces the quality degradation of grain caused by temperature fluctuations during storage. This helps maintain the freshness and nutritional value of the grain and extends its shelf life.

[0025] The three-in-one intelligent temperature-controlled grain storage system provided by the embodiment of the present invention integrates equipment such as an air conditioning unit 200 and an air-inflating and gas-generating unit 300, achieving an organic combination of temperature control and atmosphere control. This design not only improves the flexibility and adaptability of the system, but also makes operation simpler and more efficient, reducing the inconvenience and additional workload associated with frequent film removal and ventilation in traditional methods. The ability to ventilate the grain without removing the film throughout the entire cycle significantly reduces the workload of custodians, while also preventing the impact of external moisture or dry air on grain quality, particularly preventing excessive moisture loss in winter.

[0026] Further, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the control unit includes a central processing unit 400, temperature and humidity sensors 410 respectively arranged in the grain pile 110, the first space 130 and the second space 140, and a gas concentration detector 420 arranged in the grain pile 110. The air conditioning device 200, the air outlet valve 250, the inflation and gas production unit 300, the main air valve 321, the integrated air conditioning valve 311, the temperature and humidity sensors 410 and the gas concentration detector 420 are all connected to the central processing unit 400.

[0027] It is understood that by integrating temperature and humidity sensor 410 and gas concentration detector 420, the system can automatically adjust the operating status of air conditioning unit 200 and gasification unit 300 based on real-time data. This intelligent management method improves operational accuracy and response speed, reduces manual intervention, and ensures that environmental parameters are always within the ideal range, which is conducive to improving grain preservation quality.

[0028] Further, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the three-in-one intelligent temperature-controlled grain storage system further includes a circulation unit, which includes a circulation pipe 510, a first air inlet pipe 520 arranged in the grain pile 110, a second air inlet pipe 530 arranged in the first space 130, and a third air inlet pipe 540 arranged in the second space 140. The air outlet end of the circulation pipe 510 is connected to the air-conditioning device 200, and the air outlet ends of the first air inlet pipe 520, the second air inlet pipe 530, and the third air inlet pipe 540 are all connected to the air inlet end of the circulation pipe 510. The first air inlet pipe 520, the second air inlet pipe 530, and the third air inlet pipe 540 are all provided with an air inlet valve 550, and the air inlet valve 550 is connected to the central processing unit 400.

[0029] As can be appreciated, the design of the circulation unit facilitates efficient air circulation without removing the cover film 120, ensuring uniform distribution of temperature and gas composition throughout the granary and preventing extreme conditions in localized areas. Furthermore, the provision of an air inlet valve 550 and its connection to the central processor 400 enables automated management, further reducing the workload of staff.

[0030] Preferably, according to some embodiments of the present invention, the aeration and gasification unit 300 includes one or more of a nitrogen filling and nitrogen generation device, a carbon dioxide vaporizer device, and a chlorine dioxide generator.

[0031] It is understood that various types of aeration equipment can be selected according to actual conditions, and the gas composition in the grain pile 110 can be flexibly adjusted as needed to achieve the best preservation effect. This method is not only environmentally friendly, but also avoids the use of chemicals, reducing potential risks to human health and the environment.

[0032] Further, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the three-in-one intelligent temperature-controlled grain storage system also includes an exhaust unit, which includes a first exhaust pipe 610. The air inlet end of the first exhaust pipe 610 is connected to the mixing pipe 320 and is located between the air supply pipe 310 and the main air valve 321. The air outlet end of the first exhaust pipe 610 is connected to the outside world and is connected to a first exhaust fan 620. The first exhaust pipe 610 is provided with a first valve 630. The first exhaust fan 620 and the first valve 630 are both connected to the central processor 400.

[0033] It is understood that by providing the first exhaust pipe 610 and connecting the outlet end to the outside world, excess or unsuitable gas can be quickly discharged when necessary to maintain a stable internal environment. The exhaust fan and valve connected to the central processing unit 400 can be remotely controlled, improving the flexibility and safety of the system.

[0034] Preferably, according to some embodiments of the present invention, three first exhaust pipes 610 are provided and are evenly distributed in the warehouse body 100 .

[0035] It can be understood that the evenly distributed exhaust pipes ensure the consistency of the gas composition in each part of the warehouse body 100, avoid the situation where the overall environment is affected by local gas accumulation, and further enhance the stability and reliability of the system.

[0036] Further, refer to Figure 1 and Figure 2According to some embodiments of the present invention, the exhaust unit further includes a second exhaust pipe 640, the air inlet end of the second exhaust pipe 640 is connected to the first space 130, the air outlet end of the second exhaust pipe 640 is connected to the outside and is connected to a second exhaust fan 650, the second exhaust pipe 640 is provided with a second valve 660, and the second exhaust fan 650 and the second valve 660 are both connected to the central processing unit 400.

[0037] It is understood that the second exhaust pipe 640 is dedicated to exhausting the first space 130, helping to quickly remove unsuitable gases from the area and maintain a suitable storage environment. The central processor 400 connects and controls the second exhaust fan 650 and the second valve 660, enabling precise control and improving the adaptability and efficiency of the system.

[0038] Further, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the exhaust unit further includes a third exhaust pipe 670, the air inlet end of the third exhaust pipe 670 is connected to the second space 140, the air outlet end of the third exhaust pipe 670 is connected to the outside and is connected to a third exhaust fan 680, the third exhaust pipe 670 is provided with a third valve 690, and the third exhaust fan 680 and the third valve 690 are both connected to the central processing unit 400.

[0039] It can be understood that the third exhaust pipe 670 performs exhaust treatment on the second space 140, ensuring excellent environmental conditions near the surface of the grain pile 110, helping to prevent external moisture intrusion and excessive loss of internal water, and is particularly suitable for meeting storage needs in dry winter environments.

[0040] Further, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, a solar panel assembly is fixedly mounted on the top outer surface of the warehouse body 100 , and the solar panel assembly is electrically connected to the air conditioning device 200 .

[0041] It is understandable that using solar panels to power the system not only saves energy and reduces operating costs, but also embodies the concept of green environmental protection. Especially in areas with sufficient sunshine, this design can significantly reduce electricity consumption and improve economic benefits.

[0042] Furthermore, according to some embodiments of the present invention, the inner and outer surfaces of the warehouse body 100 are coated with thermal insulation coatings, and the thermal insulation coatings include but are not limited to ceramic thermal insulation coatings, composite silicate thermal insulation coatings, polyurethane foam coatings and heat reflective thermal insulation coatings.

[0043] Among them, ceramic thermal insulation coatings contain tiny ceramic particles that can reflect and scatter solar radiation, reduce heat absorption, are suitable for exterior walls and roof surfaces, and can effectively reduce indoor temperatures; composite silicate thermal insulation coatings are based on natural minerals such as silicates, have good air permeability and weather resistance, and provide effective thermal insulation effects, making them suitable for walls that require moisture-proof treatment; polyurethane foam coatings expand to form a layer of foam after construction, providing excellent thermal insulation performance, which can not only prevent heat conduction, but also has a certain waterproof function, making it suitable for roofs and walls in new buildings or renovation projects; heat-reflective insulation coatings mainly reduce the absorption of solar energy through high reflectivity, and usually contain special pigments or additives to enhance their reflective ability. Therefore, they are widely used on the facades and roofs of buildings to help reduce air conditioning energy consumption in summer.

[0044] It is understood that coating the interior and exterior surfaces of the silo 100 with a thermal insulation coating can effectively reduce heat transfer and maintain internal temperature stability. This is crucial for maintaining ideal storage conditions, especially in extreme climates, as it significantly improves the system's thermal insulation performance and protects the grain from external temperature fluctuations.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the spirit of the present invention.
