Ultraviolet disinfection device with self-cleaning function

Abstract

The invention relates to the field of disinfection equipment and in particular relates to an ultraviolet disinfection device with a self-cleaning function. The ultraviolet disinfection device comprises a hollow pipe body, wherein the pipe body is provided with a water inlet and a water outlet; the pipe body is internally provided with a transparent sleeve; the sleeve is internally provided with anultraviolet lamp tube; the ultraviolet disinfection device with the self-cleaning function further comprises a driving impeller and a cleaning belt which are connected with each other; the cleaning belt is arranged along the length direction of the pipe body and a hairbrush is arranged at one side, close to the pipe body, of the cleaning belt; the driving impeller is configured to rotate when water in the pipe body flows; the cleaning belt is in sliding contact with the peripheral surface of the sleeve through the hairbrush. According to the ultraviolet disinfection device with the self-cleaning function, provided by the invention, the ultraviolet sleeve can be cleaned through water flow; the ultraviolet disinfection device is stable to use and good in cleaning effect; an external power source is not needed and the disinfection effect is ensured under the condition that a disinfection pipe is used for long time. Furthermore, the disinfection effect on fluid with relatively high temperature is much higher than that of an existing disinfection pipe.

Description

technical field [0001] The invention relates to the field of disinfection equipment, in particular to an ultraviolet disinfection device with self-cleaning function. Background technique [0002] The ultraviolet disinfection lamp tube is in the ultraviolet UV-C band, and the bactericidal power is the strongest in the range of 250-270nm. Since the resonance line of mercury is 2537A, this sterilizing tube can generate 253.7nm ultraviolet rays, which can denature the DNA and RNA of bacteria and viruses, and the cells cannot reproduce. Ultraviolet disinfection lamps are effective against any bacteria or viruses. Concentrated high-intensity ultraviolet rays can sterilize in a short period of time. They are widely used in the disinfection and sterilization of air, surfaces of various materials, water or other liquids. [0003] When the existing ultraviolet disinfection lamp tube is used for fluid disinfection, it is easy to produce biological or chemical scaling on the tube wall,...
