Description

Technical Field

[0001] The utility model relates to the field of carbon dioxide removal machines, in particular to a carbon dioxide removal machine for a fresh-keeping atmosphere conditioning warehouse. Background Art

[0002] A CO2 remover for a fresh-keeping controlled atmosphere storage facility is a device used to regulate and maintain the gas composition within the facility. Its primary function is to reduce the concentration of CO2 within the facility to maintain the freshness and extend the shelf life of stored fruits, vegetables, and other agricultural products. This device physically or chemically absorbs or filters the CO2 within the facility, while also potentially adjusting the concentrations of other gases, such as oxygen and ethylene, to create a suitable storage environment. CO2 removers play a vital role in controlling the respiration of fruits and vegetables, inhibiting disease development, and reducing water evaporation, making them an indispensable component of modern fruit and vegetable preservation technology.

[0003] In practice, to effectively control the carbon dioxide concentration within a fresh-keeping controlled atmosphere storage facility, a carbon dioxide removal unit is typically used to maintain a suitable atmosphere. These units are equipped with specialized fans to promote air circulation within the storage facility, ensuring that the carbon dioxide is evenly distributed throughout the facility. This design ensures that fruits and vegetables, along with other agricultural products, are preserved in an optimal atmosphere, extending their shelf life and maintaining their freshness.

[0004] However, over long-term use, fans may be affected by various substances contained in the air inside the storage facility, including, but not limited to, particles and dust generated during the decomposition of fruits and vegetables. These particles and dust may gradually accumulate on and within the fan blades, increasing resistance during operation and reducing its efficiency. Furthermore, if pesticides containing chemical ingredients are used in the storage facility, these chemicals may corrode the metal components of the fan, further affecting its normal operation and service life.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 4 As shown, a carbon dioxide removal device for a fresh-keeping controlled atmosphere storage system is shown. The device primarily comprises a controlled atmosphere storage system 1, an inlet air duct 2, a first flow storage air duct 3, a second flow storage air duct 4, a fixed box 5, and a carbon dioxide remover 6. The inlet air duct 2 is located at the front end of the controlled atmosphere storage system 1, while the first flow storage air duct 3 and the second flow storage air duct 4 are respectively mounted on the side walls of the controlled atmosphere storage system 1. The second flow storage air duct 4 and the inlet air duct 2 are respectively connected to the fixed box 5 and the carbon dioxide remover 6 to ensure air circulation throughout the system.

[0025] A specially designed filter cartridge 10 is connected to the fixed box 5 and the carbon dioxide remover 6 via a connector 11. A connecting pipe 9 is mounted on the upper sidewall of the filter cartridge 10, which is connected to a fan 7. The upper end of the fan 7 is provided with a connecting pipe 8 that connects to the first flow storage air duct 3. The combination of the filter cartridge 10 and the fan 7 filters and accelerates the flow of air within the controlled atmosphere storage, thereby improving the efficiency of carbon dioxide removal.

[0026] The upper end of the filter cartridge 10 is connected to the cover 12 via fastening bolts 14. A convenient connector 13 is mounted on the upper end of the cover 12, allowing for easy opening of the cover 12 and replacement of the filter cloth within the filter cartridge 10. To ensure a tight and stable connection, a butt joint 8 is connected to the first flow storage air duct 3 and the fan 7 via a connecting flange, bolts, and nuts. Sealing strips are also bonded to the upper and lower ends of the butt joint 8 to prevent gas leakage.

[0027] Connecting pipe 9 and filter cartridge 10 are perpendicular to each other and connected to fan 7 via a flange. A sealing ring is installed at the air outlet of the connecting pipe 9 and fan 7 to ensure a tight connection. Joint 11 is welded to filter cartridge 10 and a sealing ring is installed at the joint. Joint 11 has a flange at its end, which connects to carbon dioxide remover 6, ensuring the stability and tightness of the equipment.

[0028] Furthermore, the cover 12 has a T-shaped cross-section and a sealing ring at its connection with the filter cartridge 10 to ensure a tight seal between the two. The connector 13 is U-shaped and connected to the cover 12 via a rotating shaft, making opening and closing the cover 12 more convenient. This design not only improves the device's operational convenience but also ensures a tight seal and stability during operation, thereby ensuring the efficient operation of the CO2 removal machine.

[0029] The usage process is as follows: First, ensure that the inlet air duct 2, the first flow air duct 3, and the second flow air duct 4 of the controlled atmosphere storage body 1 are properly installed, and that the connection between the carbon dioxide remover 6 and the fixed box 5 is established. Start the fan 7 through the connecting pipe 9 connected to the upper side wall of the filter cartridge 10. The fan 7 draws air from the controlled atmosphere storage and filters it through the filter cartridge 10. The combination of the filter cartridge 10 and the fan 7 filters the air in the controlled atmosphere storage and accelerates its flow, improving the efficiency of carbon dioxide removal.

[0030] When the filter cloth in the filter cartridge 10 needs to be replaced, the cover 12 can be easily opened. The cover 12 is connected to the upper end of the filter cartridge 10 by fastening bolts 14. After opening the cover 12, the filter cloth can be replaced. Make sure that all connections, including the connection between the docking pipe 8 and the first flow storage air duct 3 and the fan 7, as well as the sealing ring at the connecting pipe 9 and the air outlet of the fan 7, are installed correctly to prevent gas leakage. The cover 12 is designed to be "T"-shaped and is connected to the cover 12 by a "U"-shaped connector 13, which makes the opening and closing of the cover 12 convenient. The shaft connector 13 allows the cover 12 to be easily rotated for easy operation.

[0031] Ensure that all connecting flanges, bolts, and nuts are tightened, and that the sealing strips are bonded to the upper and lower ends of the butt-joint pipe 8 to ensure the sealing and stability of the equipment during operation. During operation, monitor the carbon dioxide concentration in the controlled atmosphere storage and adjust the operating speed of the fan 7 or replace the filter cloth as needed to maintain efficient carbon dioxide removal. After completing the carbon dioxide removal task, turn off the fan 7 and disconnect the power supply to ensure that the equipment stops operating safely. This can ensure the efficient operation of the carbon dioxide removal machine in the fresh-keeping controlled atmosphere storage and extend the shelf life of food.
