Wheel set traction automatic leaning type ultraviolet inactivation device

Abstract

The invention discloses a wheel set traction automatic leaning type ultraviolet inactivation device. The device is characterized in that an automatic cleaning mechanism is added; the automatic cleaning mechanism is arranged on a top plate of the device and consists of a motor, a proximity switch, a drum wheel, a pulley wheel set, a steel wire rope, a cleaning plate and a cleaning ring; the motor is connected with the drum wheel by a shaft; two ends of the steel wire rope are fixedly arranged on the drum wheel; the direction of the middle of the steel wire rope is changed by pulley wheels; the number of turns by means of axial rotation when the device runs can be counted; and when the motor drives the drum wheel to turn, one end of the steel wire rope moves in a winding way, and the other end of the steel wire rope is discharged to linearly move, the cleaning plate moves due to the movement of the steel wire rope, and the cleaning ring is sequentially used for cleaning the surface of a quartz socket tube in a scratching way. According to the device, the problem of the decrease of an inactivation effect caused by the scale formation of the quartz socket tube can be solved. The device is low in resistance, high in water quality applicability, high in automaticity degree, and stable and reliable to clean. The maintaining workload can be effectively reduced. The use reliability and the maintainability can be improved, and the popularization of ultraviolet rays taken as a disinfection method can be promoted.

Description

technical field [0001] The invention relates to the technical field of inactivation and disinfection equipment, in particular to a self-cleaning ultraviolet inactivation device which uses ultraviolet light to inactivate microorganisms. Background technique [0002] Ultraviolet disinfection is an efficient, safe, environmentally friendly and economical technology that can effectively extinguish pathogenic viruses, bacteria and protozoa in fire water. Therefore, this technology has been used in the disinfection treatment of clean water, sewage, reused water and industrial water in recent years It has been widely used. It has the advantages of spectrum sterilization, low sensitivity to water quality, and minimal by-products. It has gradually replaced chlorine disinfection as the most mainstream disinfection method. [0003] Since the UV lamp cannot be directly submerged in water, when it is used for water treatment, it is necessary to set a quartz sleeve outside the UV lamp tub...

Problems solved by technology

Scaling of the casing is due to the heat generated by the ultraviolet lamp during operation, which causes various impurities in the water to deposit on the surface of the casing. This layer of dirt blocks the ultraviolet rays, so that part of the ultraviolet rays cannot directly act on microorganisms, thus Affected the inactivation effect

[0004] In order to avoid casing fouling, the surface of the casing must be cleaned frequently. At present, there are two main ways to clean the surface of the casing: manual and automatic. One is a manual cleaning type UV deactivation device. The cleaning effect is good, but the casing needs to be taken out and scrubbed after cleaning, which is labor-intensive and needs to stop the operation of the system. It is not suitable for systems with a large number of lamp tubes and high requirements for continuous operation; the second is the automatic cleaning type UV extinguisher. Active device, this kind of device mainly adopts hydraulic transmission or screw transmission to work. It is well known that the structure of hydraulic transmission is complex, the requirements for supporting facilities are high, the friction resistance of screw transmission is large, and the requirements for water quality are high. If there are impurities, it is easy to cause damage to the transmission mechanism Stuck

However, the above two cleaning methods for the UV deactivation device have certain defects. At present, Shanghai Jiazhou Environmental Protection Electromechanical Equipment Co., Ltd. has developed a UV deactivation device with an automatic cleaning mechanism.
