Deep ultraviolet-based all-directional disinfection device for cold chain cargoes

Abstract

The invention discloses a deep ultraviolet-based all-directional disinfection device for cold chain cargoes, and relates to cold-chain cargo disinfection. The all-directional disinfection device comprises a housing, conveying belts, grooves, deep ultraviolet light source lamp arrays, distance measuring sensors, a main control chip, safety curtains, a power box, a gravity sensor and a base; the safety curtains are installed on two sides of the housing correspondingly; three conveying belts are installed under the housing and a groove is formed by a gap between every two conveying belts; the distance measuring sensors are mounted on the upper surface and left and right side surfaces of a distance measuring region; the power box is installed on the upper side face of the housing; and the main control chip is placed at the left side of the power box. The all-directional disinfection device is safe, and has no toxicity and pollution; the deep ultraviolet light source lamp arrays are mounted in the grooves correspondingly, and can have a very good disinfection effect on bottoms of the cargoes; on and off of the conveying belts and lamps are controlled through gravity sensors, so that energy consumption when no cargoes are present on the conveying belts can be reduced; and the distance between the cargoes and upper and side deep ultraviolet light source lamp arrays is measured through the distance measuring sensors, the speed of the conveying belts can be flexibly adjusted, efficiency is improved, and a safety guarantee is provided for transportation of the cold chain cargoes.

Description

technical field [0001] The invention relates to the technical field of cold chain goods disinfection, in particular to a deep ultraviolet-based all-round disinfection device for cold chain goods. Background technique [0002] If the imported cold chain food or packaging is positive for the new coronavirus, it is urgent to sterilize the cold chain goods. [0003] The traditional chemical disinfection method is corrosive to the outer packaging and disinfection equipment, and it is not easy to clean; the applicable conditions of high-temperature sterilization have great limitations, and many goods are not suitable for high-temperature environments; the oxidative and corrosive properties of ozone disinfection also limit its scope of action. The new coronavirus is sensitive to ultraviolet rays and heat, and the scientific and reasonable use of ultraviolet rays can effectively inactivate the coronavirus. The most widely used ultraviolet disinfection on the market is the ultravio...

Problems solved by technology

The most widely used ultraviolet disinfection on the market is the ultraviolet mercury lamp, but the mercury lamp has many disadvantages, such as bulky shape, long opening time, fragile, highly toxic, etc., especially after the signing of the Minamata Convention, mercury has been greatly restricted The use of deep ultraviolet light source ultraviolet germicidal lamps to replace traditional gas ultraviolet light sources such as ultraviolet mercury lamps has become the general trend
