Description

TECHNICAL FIELD

[0001] The utility model relates to the field of controlled atmosphere storage gas detection control, especially to a kind of controlled atmosphere storage gas detection control device. BACKGROUND

[0002] The controlled atmosphere storage gas detection control device is a device for adjusting and monitoring the environment in the controlled atmosphere storage. The controlled atmosphere storage is a storage method that prolongs the shelf life and maintains the quality of food by changing the gas composition in the storage. The main functions of the gas detection control device include: detecting the concentration of oxygen, carbon dioxide, ethylene and other gases in the storage. According to the set parameters, the gas composition in the storage is automatically adjusted to achieve the best preservation effect. The temperature and humidity in the storage are monitored in real time to ensure environmental stability. Data is collected through sensors and analyzed and processed through the control system. When the gas concentration deviates from the preset range, the alarm system is automatically started to remind the operator to intervene. Remote control and monitoring are possible, which is convenient for managers to understand the situation in the storage and make adjustments. This device is of great significance for fresh fruits and vegetables, flowers, seeds and other products that need to be stored for a long time, as it can effectively prolong the shelf life and maintain the quality.

[0003] In the current practical application of the controlled atmosphere storage gas detection control device, the gas detection equipment and the ventilation control equipment are usually arranged in different positions. This design allows the gas detection head to be installed in key areas of the storage, ensuring accurate monitoring of gas concentration at different positions in the storage. However, if the gas detection master control and the ventilation control equipment are also installed in a scattered manner, some disadvantages may arise.

[0004] Firstly, the scattered installation method significantly increases the complexity of the installation process. This not only requires more wiring work, but also requires individual debugging of each device to ensure that they can work together. This complexity not only exists in physical installation, but also includes system integration and debugging difficulties, which may lead to prolonged installation period and increased cost.

[0005] Secondly, the scattered layout also brings inconvenience to maintenance once the equipment fails. Maintenance personnel need to check and maintain in multiple locations, which not only increases maintenance cost, but also may affect the normal operation of the controlled atmosphere storage. In emergency situations, quickly locating and repairing the fault point is particularly important, and the scattered device layout may delay the fault response time, affecting the operation efficiency and safety of the entire controlled atmosphere storage.

[0016] Compared with prior art, the utility model has the following beneficial effects:

[0017] It is crucial to monitor the oxygen content inside the controlled atmosphere storage in real-time, as it directly affects the freshness and shelf life of the stored agricultural products. To ensure that the oxygen concentration within the storage environment remains at an appropriate level, we employ advanced technology that allows precise control over the flow of oxygen and air through the use of valves on the oxygen and air supply lines. This precise regulation enables the adjustment of the gas composition within the storage to meet the specific needs of different agricultural products, providing optimal preservation conditions for each type of product.

[0018] Additionally, the use of flow meters ensures the accuracy and stability of the oxygen supply, which is essential for maintaining the ideal gas environment within the controlled atmosphere storage. Flow meters allow real-time monitoring of oxygen flow and ensure precise control over the supply, preventing damage to agricultural products caused by excessive or insufficient oxygen concentration.

[0019] In terms of design, we prioritize flexibility, allowing operators to choose between manual and automatic control modes based on actual conditions. This design flexibility not only enhances the convenience of using the device but also significantly improves work efficiency. In terms of pipe connections, we use U-shaped pipe connections and clamp fixation to enhance the stability of pipe connections and effectively reduce the risk of gas leakage. Meanwhile, through bolt fixation and wire laying, we ensure the stability and reliability of signal transmission, thereby improving the accuracy of monitoring data.

[0020] To ensure the long-term stable operation of the device, we also develop strict periodic inspection and maintenance plans. These measures help to identify and address potential problems in a timely manner, extending the service life of the equipment and reducing maintenance costs. Furthermore, the high degree of automation of the device significantly reduces the likelihood of human error, reduces labor intensity, and further improves work efficiency. Through these comprehensive measures, we ensure the stability of the internal environment of the controlled atmosphere storage and the high-quality storage of agricultural products.

[0028] The support frame 3 is equipped with a first connecting pipe 7 and a second connecting pipe 13, which are respectively connected to an oxygen supply pipe 11 and an air supply pipe 12. These pipes extend into the controlled atmosphere storage room, allowing oxygen and air to flow into the room through the oxygen supply pipe 11 and the air supply pipe 12 to regulate the gas composition inside the room.

[0029] The oxygen supply pipeline 11 is equipped with a flow meter 8 and a second valve 10. The flow meter 8 monitors the oxygen content flowing into the controlled atmosphere storage to ensure that the oxygen supply meets the set standards. The air supply pipeline 12 is equipped with a first valve 9 to control the inflow of air. The oxygen supply pipeline 11 and the air supply pipeline 12 can be used individually or simultaneously as needed.

[0030] The gas control box 4 is bolted to the support frame 3, and its front end is equipped with a display screen to show the data detected by the gas monitor 5. The gas monitor 5 is connected to the gas control box 4 via wires laid along the inner cavity of the support frame 3 to ensure the stability and reliability of signal transmission. The probe of the gas monitor 5 extends into the controlled atmosphere storage room, enabling it to directly detect the oxygen content inside and provide accurate data to the gas control box 4.

Ensure that the wires of the gas monitor 5 are laid along the inner cavity of the support frame 3 to ensure the stability and reliability of signal transmission. Extend the probe of the gas monitor 5 into the controlled atmosphere warehouse to ensure that it can directly detect the oxygen content in the warehouse.

[0034] Usage process: Turn on the power switch of the gas control box 4 to start the gas detection control device. The gas monitor 5 starts to monitor the oxygen content in the controlled atmosphere warehouse in real time and transmits the data to the gas control box 4.

According to the data on the display screen, the operator can manually or automatically adjust the valves on the oxygen pipeline 11 and the air pipeline 12 to control the inflow of oxygen and air, thereby adjusting the gas composition in the warehouse. The flow meter 8 is used to monitor the oxygen content flowing into the controlled atmosphere warehouse, ensuring that the supply of oxygen meets the set standard.
