Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of carbon dioxide concentration regulating equipment, and in particular to a carbon dioxide concentration regulating device for fruit preservation warehouses. Background Technology
[0002] In the field of fruit preservation, modified atmosphere storage technology is crucial, and the precise control of carbon dioxide concentration directly affects the preservation effect. Currently, traditional carbon dioxide concentration regulating devices commonly used in fruit cold storage facilities have many drawbacks.
[0003] When the carbon dioxide concentration inside the storage facility is too high, traditional equipment mainly relies on drawing in outside air for dilution. However, this operation inevitably leads to an increase in the oxygen concentration inside the storage facility. In a high-oxygen environment, the respiration and oxidation reactions of fruits are significantly amplified.
[0004] On the other hand, fruits continuously produce carbon dioxide during respiration, but traditional devices cannot recover and reuse this carbon dioxide, resulting in resource waste. Furthermore, when the carbon dioxide concentration in the storage is too low to meet the fruit preservation requirements, traditional devices need to pump carbon dioxide into the storage tank. However, this method is not only costly, but the frequent replacement of carbon dioxide cylinders also increases labor costs and operational complexity. Moreover, long-term use consumes a large amount of carbon dioxide, which contradicts the principles of energy conservation and emission reduction.
[0005] Therefore, this application provides a carbon dioxide concentration regulating device for fruit preservation warehouses. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] like Figures 1 to 4 As shown, this application provides a carbon dioxide concentration regulating device for fruit preservation storage, comprising:
[0026] The regulating device 100 includes a housing 10, on which a control panel 13 is provided and an regulating mechanism 20 and a monitoring mechanism 30 are respectively connected to the control panel 13. An air inlet pipe 11 is fixedly installed on one side of the lower wall of the housing 10, and an air outlet pipe 12 is fixedly installed on the outer right side of the housing 10. The regulating mechanism 20 is located inside the housing 10, and the monitoring mechanism 30 is located on the outer side of one side of the housing 10.
[0027] After adopting the above technical solution, when the carbon dioxide concentration in the cold storage is high, the regulating mechanism 20 adsorbs the carbon dioxide in the cold storage, which can effectively reduce the carbon dioxide concentration in the cold storage and store the excess carbon dioxide. When the carbon dioxide concentration in the cold storage is low, the regulating mechanism 20 desorbs the carbon dioxide and releases the stored carbon dioxide, thereby reducing the consumption of carbon dioxide. The monitoring mechanism 30 monitors the carbon dioxide concentration at various levels in the cold storage and releases carbon dioxide, thereby improving the accuracy of carbon dioxide regulation.
[0028] It should be noted that the electric slider 33 moves up and down along the outer wall of the guide rail 32, thereby causing the carbon dioxide sensor 34 on the outer wall of the electric slider 33 to monitor the carbon dioxide concentration at different levels in the cold storage. When the carbon dioxide concentration at a certain height is detected to be too high, an electrical signal is transmitted to the control panel 13, which then controls the fan 21 to work. The fan 21 draws air from the cold storage into the shell 10. The air entering the shell 10 passes through the zeolite molecular sieve 24, which traps and stores some of the carbon dioxide in the air. The air after the carbon dioxide is trapped enters the exhaust port 35 through the exhaust pipe 12 and... The carbon dioxide is blown into the cold storage, thereby reducing the concentration of carbon dioxide inside. When the carbon dioxide concentration at a certain height is detected to be low, an electrical signal is transmitted to the control panel 13, which then controls the vacuum pump 23 to work. The vacuum pump 23 evacuates the inside of the shell 10. During this process, the pressure inside the shell 10 continuously decreases, and the carbon dioxide in the zeolite molecular sieve 24 diffuses to the outside due to the pressure difference. The desorbed carbon dioxide is transported to the designated height through the exhaust port 35, thereby achieving the effect of increasing the carbon dioxide concentration. In the process of adjusting the carbon dioxide, the oxygen content in the cold storage is not increased, and the carbon dioxide produced by the respiration of the fruit can be reused.
[0029] In an optional embodiment, the regulating mechanism 20 includes a fan 21, a mounting base 22, and a vacuum pump 23 fixedly installed on the inner wall of the housing 10. The fan 21 is located directly above the air inlet pipe 11, and the mounting base 22 is located to the right of the fan 21. A zeolite molecular sieve 24 is fixedly installed on the upper surface of the mounting base 22. The vacuum pump 23 is located to the right of the mounting base 22. The zeolite molecular sieve 24 traps and stores some carbon dioxide in the air, thereby reducing the concentration of carbon dioxide. The vacuum pump 23 draws a vacuum, causing the carbon dioxide in the zeolite molecular sieve 24 to diffuse to the outside due to the pressure difference, thereby increasing the concentration of carbon dioxide.
[0030] In one optional embodiment, solenoid valves 14 are fixedly installed on the outer walls of both the air inlet pipe 11 and the air outlet pipe 12 to automatically open and close the air inlet pipe 11 and the air outlet pipe 12.
[0031] In an optional embodiment, the monitoring mechanism 30 includes a connecting rod 31 fixedly installed on one side of the outer wall of the housing 10. A guide rail 32 is fixedly installed on one side of the connecting rod 31. An electric slider 33 is slidably connected to the outer wall of the guide rail 32. A carbon dioxide sensor 34 is fixedly installed on one side of the outer wall of the electric slider 33, and an exhaust port 35 is fixedly installed on the other side of the outer wall. The exhaust port 35 is fixedly connected to the side of the exhaust pipe 12 away from the housing 10. By moving the electric slider 33 up and down along the guide rail 32 in conjunction with the carbon dioxide sensor 34, the carbon dioxide concentration at different horizontal levels in the cold storage can be monitored. At the same time, by moving the electric slider 33 up and down along the guide rail 32 in conjunction with the exhaust port 35, carbon dioxide can be accurately released into a designated area, thereby improving the accuracy of the equipment.
[0032] In one optional embodiment, a through groove adapted to the air outlet pipe 12 is provided on the outer wall of one side of the guide rail 32, providing sufficient moving space for the air outlet pipe 12 during the movement of the electric slider 33.
[0033] In one optional embodiment, the control panel 13 is provided with control buttons and a display screen on its outer side, and a control circuit board and a battery are provided inside the control panel 13. The control panel 13 is electrically connected to the solenoid valve 14, the fan 21, the vacuum pump 23, the electric slider 33 and the carbon dioxide sensor 34. The control panel 13 controls the solenoid valve 14, the fan 21, the vacuum pump 23, the electric slider 33 and the carbon dioxide sensor 34 to start and stop automatically, thereby automatically increasing or decreasing the carbon dioxide concentration.
[0034] In an optional embodiment, dustproof nets are fixedly installed inside the air inlet pipe 11 and the exhaust port 35 to prevent dust from the outer wall from entering the interior of the housing 10 and to avoid dust reducing the adsorption effect of the zeolite molecular sieve 24.
