Automatically cleaned ultraviolet water sterilizer

Abstract

The invention discloses an automatically cleaned ultraviolet water sterilizer which comprises a shell, a lamp tube, a sleeve, a cleaning device, a magnetic transmission device and a driving device. The cleaning device is used for cleaning the sleeve, the magnetic transmission device is used for driving the cleaning device, the driving device is connected with the magnetic transmission device, themagnetic transmission device sleeves the outer wall of the shell, the cleaning device is positioned inside the shell and sleeves the outer wall of the sleeve, the driving device drives the magnetic transmission device to reciprocate along the outer wall of the shell, and the magnetic transmission device drives the cleaning device to reciprocate along the outer wall of the sleeve. The ultraviolet water sterilizer is small in mounting space, more uniform in ultraviolet radiation and free from lateral moment in the cleaning process, easily rusting components are isolated from sewage, secondary pollution is prevented, and the service life of the sterilizer is prolonged.

Description

technical field [0001] The invention relates to the technical field of ultraviolet equipment cleaning, in particular to an automatic cleaning ultraviolet water sterilizer. Background technique [0002] Ultraviolet disinfection technology is widely used in municipal sewage treatment, water reuse, municipal drinking water disinfection, food, beverage, semiconductor, pharmaceutical engineering and other industrial process water disinfection and aquaculture, commercial and small civil water and environmental chemical pollutants disinfection. For long-term use of UV disinfection equipment, due to the aging of the UV lamp tube and the dirt of the sleeve, the ultraviolet intensity will gradually decrease with the increase of the use time. The accumulation of inorganic and organic solids on the quartz sleeve of the UV lamp tube will cause it to enter the surrounding water body The rate of fouling build-up varies with process and effluent type, being faster when high concentrations o...

AI Technical Summary

Problems solved by technology

The automatic cleaning device sets the lead screw in a stainless steel sleeve, and then transmits the driving force to the cleaning mechanism outside the stainless steel sleeve through magnetic coupling. Although this scheme isolates the transmission devices such as the lead screw from the water, its The outer magnet has been placed in the water body for a long time, and it needs to be waterproofed, otherwise the magnet will be damaged soon; in addition, this scheme also requires a symmetrical layout, that is, the lamp tubes should be evenly distributed on both sides of the screw or around the outer side, and it takes up a lot of space. It cannot solve the automatic cleaning problem of a small ultraviolet water sterilizer with only one lamp tube

[0007] In short, for the UV water sterilizer with multiple (≥2) lamp tubes inside, the technical solutions disclosed in Chinese Patent 2009101080619, Chinese Patent 2016106144655 and Chinese Patent 2009100938105 can realize automatic cleaning of the UV water sterilizer, but It cannot solve the automatic cleaning problem of a small ultraviolet water sterilizer with only one lamp tube

On the one hand, the shell of a small ultraviolet water sterilizer with only one lamp tube is relatively small, and the space is very limited, and it cannot accommodate the lamp tube and the driving screw or rodless cylinder at the same time. The problem of insufficient space, such as a scheme that can realize automatic cleaning of ultraviolet water sterilizers published in Chinese patent 2009201415622, the cleaning mechanism that drives a lamp tube on one side of the driving device will generate a large lateral moment during the working process, resulting in sideways cleaning of the cleaning mechanism. Tilting, the compression damages the quartz sleeve, which seriously affects the life of the quartz sleeve and the cleaning mechanism; moreover, because of the blocking of the driving device (screw or rodless cylinder), the distribution of ultraviolet illuminance inside the housing of the ultraviolet water sterilizer will also be uneven. Balanced, affecting the disinfection effect

[0008] That is, the existing technology cannot simultaneously solve the problems of automatic cleaning of a small-scale ultraviolet water sterilizer with only one lamp tube, avoiding the lateral torque that causes the cleaning mechanism to tilt, and ensuring the balanced distribution of ultraviolet illuminance, etc.
