[0022] An embodiment of the utility model provides an oxygen remover for a fresh-keeping storage, as Figures 1-4As shown in the figure, it includes a support base 1; a tank body 2 provided on the support base 1; a control console provided beside the tank body 2; a first air duct 3 provided beside the support base 1; a first one-way valve 4 provided on the first air duct 3; the first air duct 3 extends to a position on one side of the inner cavity of the support base 1 and is connected to a first filter box 5; a second filter box 6 provided beside the first filter box 5, and the first filter box 5 and the second filter box 6 are connected and communicated through a second air duct 7; a rotating shaft 8 rotating at the bottom position of the inner cavity of the second filter box 6; stirring blades 9 provided on the outer side of the rotating shaft 8; a temperature sensor 10 and an electric heating block 11 provided on the side wall of the second filter box 6; a blower 12 provided at the top position of the second filter box 6, and one end of the blower 12 is connected and communicated with the second filter box 6; the other end of the blower 12 is connected and communicated with the tank body 2.

[0023] It should be noted that due to the problems of low efficiency, unstable effect, complex equipment and high maintenance cost in traditional oxygen removal operation and treatment; the low efficiency is difficult to meet the large-scale demand, and the unstable effect affects the fresh-keeping quality. Through the integrated application of multi-layer filtration and deep deoxidation technology, this solution realizes the precise control of the oxygen concentration in the gas in the fresh-keeping warehouse, achieving an ideal low-oxygen environment; this environment innovatively inhibits the respiration of fruits and vegetables and the activities of microorganisms, significantly extending the fresh-keeping period. In addition, this device also integrates intelligent monitoring and safety protection design. Through real-time sensor feedback and automatic adjustment mechanism, it ensures the stability of the deoxidation effect and the safe operation of the equipment without worry; this highly integrated fresh-keeping solution not only improves the overall quality of fruit and vegetable storage, but also reduces losses and waste, providing a solid and reliable guarantee for the long-term storage of fruits and vegetables in the fresh-keeping warehouse.

[0024] Specifically, in this embodiment, this solution mainly includes a support base 1; the gas in the fresh-keeping warehouse is first introduced into the equipment through the first air duct 3 and enters the first filter box 5; in the first filter box 5, the gas undergoes preliminary filtration treatment, effectively removing large-particle impurities therein, providing a clean gas source for the subsequent deoxidation process; subsequently, the preliminarily filtered gas enters the second filter box 6; in the second filter box 6, the stirring blades 9 start to rotate, and through their stirring action, sufficient contact and mixing between the gas and the deoxidation medium are achieved; at the same time, the electric heating block 11 is started to heat the gas or the deoxidation medium to promote the occurrence of the deoxidation reaction; this process combines physical adsorption and chemical reaction, effectively removing the oxygen in the gas.

[0025] The gas that has completed the deoxidation treatment is sent into the tank body 2 under the strong action of the blower 12; the tank body 2 is also filled with a deoxidation medium, and they continue to adsorb the residual oxygen in the gas entering the tank body 2 until the oxygen concentration in the tank body 2 drops below the preset threshold, thus realizing the cyclic deoxidation of the gas.

[0026] To ensure that the deoxidation reaction proceeds under optimal conditions, the temperature sensor 10 monitors the temperature inside the second filter box 6 in real time and transmits the data to the console; the console automatically adjusts the heating power of the heating block 11 according to the feedback from the temperature sensor 10 to maintain an appropriate reaction temperature;

[0027] The entire deoxidation process is carried out under the automatic monitoring and adjustment of the console, ensuring the stability of the deoxidation effect and the safety of the equipment operation; in this way, the oxygen concentration in the fresh-keeping storage is effectively controlled, providing a strong guarantee for the long-term storage of fresh products such as fruits and vegetables.

[0028] In a further preferred embodiment of the present utility model, as Figure 3 shown, an oxygen filter membrane 13 is provided inside the first filter box 5, and a molecular sieve filter membrane 14 is provided on the side of the oxygen filter membrane 13 away from the first air duct 3.

[0029] In this embodiment, the gas first passes through the oxygen filter membrane 13, and the oxygen filter membrane 13 reduces the oxygen concentration in the gas; the gas after preliminary deoxidation then enters the molecular sieve filter membrane 14, and the molecular sieve filter membrane 14 further removes or reduces the oxygen concentration and other impurity molecules in the gas by its pore size screening effect; the gas processed by the first filter box 5 enters the second filter box 6 for further deoxidation treatment, and finally is sent into the tank body 2 through the blower 12 to realize cyclic deoxidation.

[0030] In a further preferred embodiment of the present utility model, as Figure 3 shown, an adsorption layer 15 is provided inside the tank body 2, and an activated carbon filter membrane 16, a nanofiber membrane 17 and a gas separation membrane 18 are sequentially provided in the adsorption layer 15 from bottom to top.

[0031] In this embodiment, when the gas in the fresh-keeping storage enters the deoxidizer through the first air duct 3, it first passes through preliminary filtration to remove large particle impurities; subsequently, the gas enters the adsorption layer 15 inside the tank body 2 for deep deoxidation treatment; in the adsorption layer 15, the gas first passes through the activated carbon filter membrane 16 for physical adsorption deoxidation; then passes through the nanofiber membrane 17 for further adsorption and diffusion deoxidation; finally passes through the gas separation membrane 18 for selective separation deoxidation; after being processed by these three adsorption layers 15, the oxygen concentration in the gas will be significantly reduced to meet the oxygen concentration requirements of the fresh-keeping storage.

[0032] In a further preferred embodiment of the present utility model, as Figure 3 shown, an oxygen concentration sensor 19 is provided at the upper part of the inner cavity of the tank body 2.

[0033] In this embodiment, the oxygen concentration sensor 19 (AO-02) can monitor the oxygen concentration in the tank body 2 in real time. Based on the monitored oxygen concentration data, the console can automatically adjust the operating parameters of the deoxidizer, such as gas flow rate, heating power, etc., to ensure the best deoxidation effect. When the oxygen concentration is higher than the set threshold, the console can start or accelerate the deoxidation process; when the oxygen concentration is lower than the set threshold, the deoxidation process can be reduced or stopped to avoid over-deoxidation.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, an exhaust port 23 communicating with its inner cavity is provided at the top of the tank body 2, and a second one-way valve 20 is provided on the exhaust port 23.

[0035] In this embodiment, the second one-way valve 20 is installed on the exhaust port 23, and its main function is to prevent gas from flowing back into the tank body 2 from the exhaust port 23. During the deoxidation process, a certain negative pressure or positive pressure state needs to be maintained in the tank body 2 to ensure the deoxidation effect. The design of the one-way valve can ensure that the gas can only flow in one direction, that is, only from the tank body 2 to the outside, and cannot flow back from the outside into the tank body 2.

[0036] In a further preferred embodiment of the present utility model, as Figure 3 shown, a servo motor 21 is provided at the bottom of the second filter box 6, and the output end of the servo motor 21 is key-fixedly connected to the end of the rotating shaft 8.

[0037] In this embodiment, the servo motor 21 is used to drive the rotating shaft 8 to rotate, thereby driving the stirring blades 9 to stir sufficiently in the washing water.

[0038] In a further preferred embodiment of the present utility model, as Figure 3 shown, mufflers 22 are provided on the first air duct 3 and the second air duct 7.

[0039] In this embodiment, the mufflers 22 provided on the first air duct 3 and the second air duct 7 can effectively reduce the noise generated during the gas flow process, which not only helps to improve the working environment and reduce the interference and harm of noise to the staff.

[0040] Working principle: The gas in the fresh storage of this device is first introduced into the deoxidizer through the first air duct 3. A muffler 22 is installed on the first air duct 3 to reduce the noise generated during the gas flow, thereby improving the working environment; after the gas enters the device, it first enters the first filter box 5, where large particle impurities are preliminarily filtered and removed, providing a clean gas source for the subsequent deoxidation treatment;

[0041] The preliminarily filtered gas then enters the second filtration tank 6. Inside the second filtration tank 6, the servo motor 21 drives the rotating shaft 8 to rotate, thereby driving the stirring blades 9 to stir thoroughly in the washing water; the rotation of the stirring blades 9 promotes the full contact and mixing between the gas and the deoxidizing medium. At the same time, the electric heating block 11 is activated to heat the gas or the deoxidizing medium, accelerating the occurrence of the deoxidation reaction; this process combines physical adsorption and chemical reactions, effectively reducing the oxygen concentration in the gas.

[0042] Before further deoxidation treatment, the gas also passes through the oxygen filtration membrane 13, which can preliminarily reduce the oxygen concentration in the gas; subsequently, the gas enters the molecular sieve filter membrane 14, which further removes or reduces the oxygen concentration and other impurity molecules in the gas by its pore size screening effect.

[0043] The gas that has completed the preliminary deoxidation treatment continues to enter the adsorption layer 15 inside the tank body 2 for deep deoxidation; in the adsorption layer 15, the gas passes through the activated carbon filter membrane 16, the nanofiber membrane 17, and the gas separation membrane 18 in sequence; the activated carbon filter membrane 16 removes oxygen molecules through physical adsorption; the nanofiber membrane 17 further adsorbs and diffuses for deoxidation; and the gas separation membrane 18 separates oxygen molecules from the gas based on its selectivity; the combined action of these three adsorption layers 15 significantly reduces the oxygen concentration in the gas, meeting the low-oxygen environment requirements needed for the fresh-keeping storage.

[0044] To ensure that the deoxidation process proceeds under optimal conditions, the temperature sensor 10 monitors the temperature inside the second filtration tank 6 in real time and transmits the data to the console; the console automatically adjusts the heating power of the electric heating block 11 according to the temperature feedback to maintain an appropriate reaction temperature; at the same time, the oxygen concentration sensor 19 monitors the oxygen concentration inside the tank body 2 in real time. When the concentration is higher than the set threshold, the console will automatically adjust the operating parameters of the deoxidizer, such as increasing the gas flow rate or heating power, to accelerate the deoxidation process; conversely, when the concentration is lower than the set threshold, the deoxidation process will be reduced or stopped to avoid over-deoxidation.

[0045] Finally, the gas that has completed the deoxidation treatment is sent into the fresh-keeping storage under the strong action of the fan 12 to achieve the cyclic deoxidation of the gas; the entire deoxidation process is carried out under the automatic monitoring and adjustment of the console, ensuring the stability of the deoxidation effect and the safety of the equipment operation; in this way, the oxygen concentration in the fresh-keeping storage is effectively controlled, providing a strong guarantee for the long-term storage of fresh products such as fruits and vegetables.

[0046] In addition, a second one-way valve 20 is installed on the exhaust port 23 at the top of the tank body 2, whose function is to prevent the gas from flowing back into the tank body 2 from the exhaust port 23, ensuring a stable pressure state inside the tank body 2 and further guaranteeing the deoxidation effect and equipment safety.
