Ultraviolet sterilizer with automatic cleaner

Abstract

An ultraviolet disinfector with automatic washing unit for the fluid (sewage or running water) is composed of the annular rubbing-washing plates, pull rod, slide rod and its guide rod, supporting rods, liquid detergent box vertically fixed to said supporting rods, liquid detergent supplying tube connected to the liquid detergent inlet of said box, the sealing unit for the liquid detergent outlet of said box, the ultraviolet tube in the sleeve pipe and passing through said rubbing-washing rings which can run through the holes on the opposite walls of said box, and drive unit.

Description

Technical field: [0001] The ultraviolet disinfection device with automatic cleaning device of the present invention belongs to the field of ultraviolet disinfection. Background technique: [0002] Most of the existing ultraviolet disinfection systems have an automatic cleaning device for the surface of the ultraviolet lamp casing. Common cleaning methods include mechanical cleaning and mechanical cleaning with chemical agents. Among them, the mechanical cleaning device drives the wiping device installed on the surface of the lamp sleeve, and wipes the surface of the lamp sleeve back and forth through the mechanical movement of the wiping device to remove the dirt on the surface of the lamp sleeve. It has a simple structure and does not need to add chemicals. Advantages, but because the ultraviolet lamp will generate high heat when it emits light, it is easy to form hard dirt on the surface of the lamp sleeve when the fluid is sterilized, and the mechanical cleaning device i...

Among them, the mechanical cleaning device drives the wiping device installed on the surface of the lamp sleeve, and wipes the surface of the lamp sleeve back and forth through the mechanical movement of the wiping device to remove the dirt on the surface of the lamp sleeve. It has a simple structure and does not need to add chemicals. Advantages, but due to the high heat generated when the ultraviolet lamp emits light, it is easy to form hard dirt on the surface of the lamp sleeve when the fluid is sterilized, and the mechanical cleaning device is not easy to remove the hard dirt, and it needs to be removed by adding chemicals

Existing mechanical and chemical agent cleaning devices, such as the patent application No. 00811520.6, include a cleaning sleeve that slides and engages with the outside of the ultraviolet lamp casing. One part is in contact, and the cleaning chamber is filled with cleaning liquid. The cleaning chamber contains an opening leading to the outside of the cleaning sleeve, and a pressure equalizing member located in the opening is used to provide a seal between the opening and the outside of the cleaning sleeve. The pressure The balance member can move along with the pressure gradient here and move the drive device of the cleaning sleeve along the outside of the ultraviolet lamp tube. This cleaning system can add chemicals to effectively clean the surface of the lamp sleeve, but its structure is complicated and difficult to manufacture , and each cleaning chamber is independently connected with the cleaning liquid adding device, and the structure is complicated, so it is necessary to add chemical agents and effectively clean the surface of the ultraviolet lamp casing, and the ultraviolet disinfection system lamp scrubbing device with simple structure and easy manufacture is necessary for ultraviolet lamps. The surface of the bushing is cleaned, reducing costs
