Double-layer bushing ultraviolet ray sterilizer

Abstract

The invention discloses a double-layer bushing ultraviolet ray sterilizer, which comprises connecting structure members, locking nuts, an inner bushing, an outer bushing, water outlets, water inlets,an ultraviolet ray lamp pipe, a reflection film, bases and a metal plate, wherein the inner bushing is arranged in the outer bushing, both ends of the inner bushing respectively extend out of both ends of the outer bushing, the two connecting structure members are fixed on both ends of the inner bushing, and fix the outer bushing on the inner bushing, a flow guiding channel is arranged between theinner wall of the outer bushing and the outer wall of the outer bushing, the connecting structure members are respectively provided with the water inlet and the water outlet, the water inlet and thewater outlet are communicated to the flow guiding channel, the locking nuts are respectively fixed on both ends of the connecting structure members, the ultraviolet ray lamp pipe is fixed in the innerbushing, the outer wall of the outer bushing is coated with a layer of the reflection film, and the lower ends of the connecting structure members are provided with the two bases and are fixed to themetal plate. According to the present invention, the double-layer bushing ultraviolet ray sterilizer has advantages of low cost, complete sterilization, science property and high efficiency.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a double-layer casing ultraviolet sterilizer. Background technique [0002] The traditional sterilizer is composed of a lamp tube, a sleeve, and a stainless steel shell. The stainless steel shell needs manual welding, which is costly and slow. In areas with high requirements such as household water purification, ultraviolet radiation on stainless steel will also produce certain odors, which will have a certain impact on water quality. The invention is patented, and the casing adopts a quartz glass casing instead of a stainless steel casing. Since stainless steel is not used as the main body (maybe part of it is still used), the cost is only one-third to one-fourth of the past, which greatly reduces manufacturing costs and improves production efficiency. [0003] The ultraviolet rays irradiated by the traditional sterilizer lamp directly hit the inner wall of the stainless steel s...

AI Technical Summary

Problems solved by technology

[0004] The stainless steel shell is generally processed manually, the outer surface is polished, and the inner surface is generally not modified. The water flows inside, and the thickness is difficult to guarantee. In places where the local thickness is thick, there will be a lot of water flow, and some parts will not flow, and there will be "dead water" "Phenomenon, so there will definitely be unevenness, which may cause uneven sterilization
