Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet disinfection devices, in particular to ultraviolet disinfection equipment with a filtering function. Background Art

[0002] During the production of electrolytic copper foil, cleaning fluid is required for the surface electroplating process. After the copper foil is treated, the cleaning fluid used needs to be discharged. These cleaning fluids contain high levels of heavy metal pollutants and are highly toxic. Direct discharge will cause great harm to the ecological environment. At present, these cleaning fluids are generally treated in combination with ion exchange processes. The cleaning fluid is filtered multiple times and then enters the reverse osmosis membrane, intermediate water tank, anion and cation exchanger, external water tank and other systems. After filtering again, the liquid is instantly sterilized and disinfected by ultraviolet rays.

[0003] The existing Chinese patent authorization announcement number CN201921595536.7 discloses an ultraviolet disinfection water tank, which includes a water tank, a water inlet pipe is arranged on one side of the water tank, a sewage outlet is arranged at the bottom end of the filter tube, a filtering mechanism is arranged at the end of the filter tube away from the water inlet pipe, a reflector is arranged on the outside of the UV ultraviolet lamp, and a heating resistance wire is installed at the bottom end of the water tank. The utility model filters the water source through the set filtering mechanism to intercept the dirt in the filter tube. When cleaning, the sewage outlet can be opened to complete the cleaning. There is no need to disassemble and clean. The cleaning time is short and the cleaning process is relatively simple. The reflector can refract the ultraviolet light emitted by the UV ultraviolet lamp to every corner of the water tank, so that the ultraviolet light can be fully utilized. The water is heated by the set heating resistance wire to meet the optimal temperature of ultraviolet disinfection, thereby improving the disinfection effect.

[0004] However, in the ultraviolet disinfection water tank provided by the above patent, the liquid will directly flow into the water tank, and will be directly discharged through the outlet after ultraviolet disinfection.

At this time, the light has a poor sterilization effect on the liquid in the lower part of the water tank, which will affect the overall disinfection effect and quality of the liquid, and needs further improvement.
