Ultraviolet sterilization device

Abstract

The invention provides an ultraviolet sterilization device. The ultraviolet sterilization device comprises a shell, and an opening is formed in one end of the shell. A rocker arm is arranged on the outer side, opposite to the opening, of the shell. A rotating shaft is fixedly arranged on the rocker arm, and drives a lamp plate to rotate at the opening along the axial direction of the rotating shaft. A plurality of V-shaped ultraviolet lamps are arranged on the lamp plate from top to bottom sequentially, and are sequentially connected in a head-to-tail mode to form a jagged ultraviolet spotlight group. A plurality of ultraviolet spotlight groups are sequentially arranged on the lamp plate from inside to outside. The ultraviolet sterilization device has the advantages that limited internal space of the shell is utilized to the greatest extent, the radiation area of water flow is increased, and ultraviolet sterilization efficiency is improved; the lamp plate is rotatable, the moving range of the ultraviolet spotlight groups on the lamp plate is widened, the radiation range of ultraviolet rays is further widened, and the water flow entering the shell can be radiated as much as possible.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to an ultraviolet disinfection device. Background technique [0002] Ultraviolet disinfection is the use of ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA or RNA in microbial cells, causing growth cell death and (or) regenerative cell death, to achieve the purpose of sterilization. Existing ultraviolet disinfection devices used in the field of water treatment are all fixedly equipped with one or more straight tube ultraviolet spotlights in the device. Because the contact area between the straight tube ultraviolet spotlights and the water to be treated (disinfected) is small, the water flow The speed is too fast, so that the time for the water flow to be irradiated by ultraviolet rays is short, so that it cannot be fully irradiated and disinfected, so the disinfection efficiency is not high. Reduce the antivirus effect; and in order to ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the present invention proposes an ultraviolet disinfection device, which solves the shortcomings of the traditional ultraviolet disinfection device, such as low antivirus efficiency, poor antivirus effect, and reduced antivirus ability after the ultraviolet spotlight is damaged.
