Description

Technical Field

[0001] The utility model relates to the field of cold chain logistics, and in particular to a cold chain container sterilization and disinfection device. Background Art

[0002] Cold chain containers are special containers with good insulation and the ability to maintain a certain low temperature, suitable for the transportation and storage of various perishable foods. On the one hand, perishable foods stored at low temperatures for a long time are prone to breed bacteria in the container, which in turn contaminates the food. On the other hand, some low-temperature resistant viruses can survive in low-temperature environments, posing a risk of transmission; therefore, during the transportation and storage process, the cold chain containers and the food in the containers need to be sterilized and disinfected.

[0003] The patent with application number 202011376246.0 provides a disinfection device and method for cold chain logistics transport containers. It can inject ozone into a closed container by setting a vacuum device and an ozone supply device. The cold chain container is placed in the closed container, and the door is opened to use ozone for sterilization and disinfection. In order to improve the disinfection effect, a vibration device is also provided to drive the closed container to vibrate, and the gaps between the food are opened by vibration, so that ozone can reach the gaps for disinfection. However, cold chain containers are also prone to damage during the vibration process, and it is not easy to fully open the gaps between the food by vibration alone. In addition, the closed container is large in size and the vibration energy consumption is high.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a cold chain container sterilization and disinfection device which has a scientific design, good disinfection effect, does not require vibration, and is not prone to damage.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cold chain container sterilization and disinfection device, comprising a sealed disinfection chamber, a vacuum pump, an ozone supply device, an air pump and an aeration pipeline laid at the bottom of each cold chain container, the vacuum pump's exhaust port is connected to the air outlet on the sealed disinfection chamber, the sealed disinfection chamber is provided with an air inflation pipeline, the air outlet of the ozone supply device is connected to the air inlet of the inflation pipeline through the air pump; the aeration pipeline comprises a diversion transverse pipe and a plurality of longitudinal branch pipes, a plurality of the longitudinal branch pipes are laid on the bottom wall of the cold chain container, a plurality of aeration ports are evenly opened on the top of the longitudinal branch pipes, one end of the longitudinal branch pipe extends out of the cold chain container and is connected to the side of the diversion transverse pipe, an inflation joint is provided in the center of the side of the diversion transverse pipe, and the air outlet of the inflation pipeline is connected to each of the inflation joints.

[0007] Based on the above, it also includes a return air pipe, and the two ends of the return air pipe are respectively connected to the return air port of the ozone supply device and the air outlet of the vacuum pump.

[0008] Based on the above, it also includes a three-way solenoid valve, two interfaces of the three-way solenoid valve are serially connected to the return air pipe, and one interface of the three-way solenoid valve is connected to the atmosphere.

[0009] Based on the above, a partition is also provided in the center of the bottom wall of the sealed disinfection warehouse, the cold chain containers are placed on both sides of the partition, and the inflation pipeline is provided on the partition.

[0010] Based on the above, the air outlet on the sealed disinfection chamber is located directly above the partition, and chamber doors are provided at both ends of the sealed disinfection chamber.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0012] (1) A cold chain container is placed in the sealed sterilization chamber, and the chamber is evacuated by the vacuum pump. The aeration pipeline is laid at the bottom of each cold chain container. The aeration pump supplies ozone to the aeration pipeline, so that the ozone enters from the bottom of the container, fully flows through the food placed in the container, and finally fills the sealed sterilization chamber, making it easier to penetrate the gaps between the food, thereby improving the sterilization effect.

[0013] (2) The setting of the air return pipe can start the circulation after the sealed disinfection chamber is filled with ozone, so that ozone can continuously overflow from the aeration pipeline and dynamically flush the food, thereby further improving the disinfection effect.

[0014] (3) The three-way solenoid valve is provided to facilitate switching the flow path of the gas in the chamber, discharging it to the atmosphere or returning it to the ozone supply device.

[0015] (4) The partition is arranged in the middle to facilitate the arrangement of cold chain containers on both sides and to facilitate connection with the inflation joint. BRIEF DESCRIPTION OF THE DRAWINGS
