[0038] In order to solve the problems in the related art to some extent, the present application provides a controlled atmosphere warehouse, which is provided with an isolation warehouse, the isolation warehouse is designed with double doors, the outer warehouse door and the inner warehouse door are opened and closed in sections, and an outer air extraction assembly and an inner air extraction assembly are matched, so as to realize dynamic balance of the gas pressure when entering or exiting the warehouse, the outer air extraction pump discharges the gas in the warehouse to the outside of the warehouse, the inner air extraction pump discharges the gas back to the warehouse, direct gas exchange between the inside and outside of the warehouse is avoided, the gas environment in the warehouse is effectively prevented from being destroyed, and the double door design can improve the sealing property of the warehouse body and reduce the energy consumption of the controlled atmosphere warehouse.

[0039] The present application will be described below in conjunction with the drawings and specific embodiments:

[0040] In conjunction with Figures 1-5This application provides a controlled atmosphere storage facility, including a controlled atmosphere storage body 10; an isolation chamber 30 is provided at the door of the controlled atmosphere storage body 10, the isolation chamber 30 includes a chamber body 31, which is located at the internal entrance of the controlled atmosphere storage body 10; an outer chamber door 32, which is located at the front end of the chamber body 31; and an inner chamber door 33, which is located at the rear end of the chamber body 31.

[0041] The storage unit 31 is directly installed at the door of the controlled atmosphere storage unit 10. The entire unit is made of thermal insulation material, which can improve the thermal insulation performance of the storage unit 31. The outer door 32 is located on the outside of the controlled atmosphere storage unit 10 to isolate the storage unit 31 from the outside space. The inner door 33 is located between the storage unit 31 and the controlled atmosphere storage unit 10 to isolate the storage unit 31 from the controlled atmosphere storage unit 10. When entering the controlled atmosphere storage unit 10, the outer door 32 is opened first to enter the storage unit 31. When entering the controlled atmosphere storage unit 10, the outer door 32 is closed and then the inner door 33 is opened to achieve isolation between the controlled atmosphere storage unit 10 and the outside world.

[0042] The interior of the chamber 31 is provided with an external air extraction assembly 40, which includes an external air extraction pump 41 installed inside the chamber 31; an external air extraction pipe 42 located at the air extraction end of the external air extraction pump 41; an external air extraction hood 43 fixedly connected to one end of the external air extraction pipe 42 and located inside the chamber 31; and an external solenoid valve 44 located at the exhaust end of the external air extraction pump 41 and located outside the controlled atmosphere storage chamber 10.

[0043] When entering the chamber 31, the external solenoid valve 44 is opened and the external air pump 41 is started. The external air pump 41 extracts the gas from the chamber 31 through the external air extraction pipe 42 and the external air extraction hood 43, so that the chamber 31 is in a negative pressure state. After the gas in the chamber 31 is extracted, the external solenoid valve 44 and the external air pump 41 are closed, and then the inner chamber door 33 is opened. This can prevent the air in the chamber 31 from damaging the gas environment inside the storage.

[0044] The interior of the chamber 31 is provided with an internal air extraction assembly 50, which includes an internal air extraction pump 51 installed inside the chamber 31; an internal air extraction pipe 52 located at the air extraction end of the internal air extraction pump 51; an internal air extraction hood 53 fixedly connected to one end of the internal air extraction pipe 52 and located inside the chamber 31; and an internal solenoid valve 54 located at the exhaust end of the internal air extraction pump 51 and located inside the controlled atmosphere storage chamber 10.

[0045] When it is necessary to release gas from the controlled atmosphere storage 10, the inner door 33 is closed, the inner solenoid valve 54 is opened, and the inner air pump 51 is started. The inner air pump 51 draws the gas in the storage 31 into the controlled atmosphere storage 10 through the inner air extraction pipe 52 and the inner air extraction hood 53. Finally, the outer door 32 is opened. This can prevent the gas in the storage from being discharged to the outside, thus avoiding the waste of gas in the storage and also preventing changes in the gas pressure in the storage caused by the discharge of gas in the storage.

[0046] The control component 60 is installed inside the chamber 31. The control component 60 is electrically connected to the external air extraction component 40 and the internal air extraction component 50.

[0047] The control component 60 is controlled by a distribution box. The electrical input terminals of the external air pump 41, external solenoid valve 44, internal air pump 51 and internal solenoid valve 54 are electrically connected to the distribution box. The external air pump 41, external solenoid valve 44, internal air pump 51 and internal solenoid valve 54 are manually controlled by the distribution box.

[0048] In some embodiments, a flexible photovoltaic panel 20 is provided on the top of the controlled atmosphere storage body 10. The flexible photovoltaic panel 20 is connected to a battery through a charging circuit, and the battery can supply power to the controlled atmosphere storage body 10.

[0049] In some embodiments, both the outer compartment door 32 and the inner compartment door 33 are opened by pushing and pulling. In order to avoid the outer compartment door 32 or the inner compartment door 33 being difficult to open due to air pressure difference, the outer compartment door 32 and the inner compartment door 33 are opened by pushing and pulling. This can prevent air pressure from adhering to the compartment door and making it difficult to open.

[0050] In some embodiments, both the outer exhaust hood 43 and the inner exhaust hood 53 have a trumpet-shaped structure. The trumpet-shaped structure of the outer exhaust hood 43 and the inner exhaust hood 53 improves the gas extraction efficiency and quickly stabilizes the air pressure inside the chamber.

[0051] In some embodiments, the control component 60 includes a mounting plate 61, which is fixedly connected to the inside of the chamber 31; an electrical control box 62, which is installed on the outer wall of the mounting plate 61 and electrically connected to the external air pump 41 and the internal air pump 51; and a pressure gauge 63, which is installed on the outer wall of the mounting plate 61. The electrical control box 62 is an electronic pressure gauge that allows manual control of the various components, and the pressure gauge 63 is an electronic pressure gauge that facilitates observation of the air pressure status inside the chamber.

[0052] In some embodiments, the control component 60 further includes a temperature and humidity meter 64 disposed on the outer wall of the mounting plate 61. The temperature and humidity meter 64 is an electronic temperature and humidity meter that can monitor the temperature and humidity inside the chamber in real time.
