Description
Technical Field
The invention relates to an ultraviolet disinfection device. In particular to an ultraviolet disinfection cabin for cold chain transportation of goods.
Background
Respiratory infectious viruses such as coronavirus, new coronary pneumonia and SARS exist in the aspects of our lives, so that people are restricted in their ways of clothes, eating and housing. At present, live viruses are detected in the outer package of frozen products, cases that the nucleic acid of the new coronavirus of the frozen products of the cold chain is positive are increased continuously, and the cold chain food which is popular with consumers in the past is covered under the shadow of the new coronavirus.
Although disease control experts indicate that the new coronavirus is not a food-borne disease, the fear of the new coronavirus can cause that many consumers have to be caught.
At present, edible seafood, especially imported seafood, has a great risk, and new coronavirus is frequently detected on the package and the surface related to cold chain food, which indicates that the virus is easier to survive in a low-temperature environment, and most viruses are resistant to low temperature and not high temperature. There are studies showing that the new coronavirus (2019-nCoV) can survive on the screen of a mobile phone for 9 days (Human coronaviruses can be used for the new respiratory diseases for up to one day, and the survival time is longer under the freezing condition.
The cold chain involves many links, the virus transmission path is wide, the links are numerous from the origin, production and processing, transportation and storage of a cold storage until final transportation reaches a point of sale, and cold chain practitioners participate in the links, so that the virus transmission risk is greatly increased.
Cold chain goods present such a safety hazard that the first time they come to mind is necessarily sterilization, in order to free cold chain practitioners from the risk of viral transmission and to enable consumers to purchase cold chain products with confidence.
Since the cold chain system is low temperature, thermal sterilization is not suitable for the cold chain system. The chemical agent can generate chemical substances harmful to human bodies, and cannot be applied to the field of food disinfection. Ozone disinfection technology is not suitable because ozone itself is harmful to human body, needs to be carried out under unmanned condition, and disinfection time is long, but cold chain system is closed and needs human hands. Radiation disinfection is also harmful to human body and is therefore not suitable. Ultraviolet disinfection technology, because there is no pungent smell and no chemical residue, can effectively kill pathogens, has been widely used in air, water and food surface, food packaging material, food processing workshop, equipment, utensil, workstation disinfection treatment now.
Cold chain products are an indispensable part in the life of people at present, and are vital to consumers and operators, and if new coronavirus is placed in the cold chain products, the safety of the daily life of people cannot be guaranteed, so that the elimination of the virus in the cold chain products is indispensable, and the cold chain products are strictly disinfected for frozen food warehouses, cold chain vehicles, frozen food packages and booths.
Disclosure of Invention
The invention aims to solve the technical problem of providing an ultraviolet disinfection cabin for cold chain transportation cargos, which can widely kill bacteria, coronavirus and new coronavirus on the cold chain cargos.
The technical scheme adopted by the invention is as follows: the utility model provides an ultraviolet ray disinfection cabin of cold chain transportation goods, includes the chassis, the preceding of chassis is provided with the n type box that link up around, the inside automation door of opening that forms of n type box through setting up at both ends the disinfection room, the middle part of disinfection room form the ultraviolet ray disinfection space through setting up the ultraviolet tube structure, the top at both ends in the disinfection room is formed with outside communicating exhaust hole, the ultraviolet ray disinfection space is provided with the cooling pipeline that is used for cooling down to the ultraviolet tube group along the inner wall, correspond on the chassis n type box is provided with the smooth roller mechanism that is used for automatic transport by the disinfection goods.
According to the ultraviolet disinfection cabin for cold chain cargo transportation, the reflecting plate is arranged on the inner container of the box body, ultraviolet rays emitted by the ultraviolet lamp towards the inner wall of the box body are reflected to the center of the box body, and the ultraviolet rays emitted by the ultraviolet lamp can kill bacteria, coronavirus and new coronavirus on cold chain cargo nearby, so that the serious problem that cold chain workers and shoppers are ill can be effectively solved. By adopting the structure of the invention, the aluminum reflecting plate can reflect the ultraviolet rays emitted by the ultraviolet lamp to the four walls to the middle of the box body, thereby improving the use efficiency of the ultraviolet rays and saving energy. Meanwhile, the ultraviolet rays emitted by the ultraviolet lamp irradiate the outer wall of the cold chain article nearby, so that the effect of killing bacteria, coronavirus and new coronavirus is better. The inlet and outlet of the ultraviolet disinfection cabin are provided with automatic opening doors, and after the structure is adopted, cold chain goods can smoothly enter the inner cavity for disinfection, and an operator can be protected from being injured by ultraviolet irradiation. The cooling tube is arranged near the ultraviolet lamp tube, so that the ultraviolet lamp can run more stably.
