Ultraviolet disinfection device with adjusting function used for sewage treatment

Abstract

The invention relates to an ultraviolet disinfection device with an adjusting function used for sewage treatment. The device comprises a sewage pool, a water inlet pipe, a water discharge pipe, a controller, a top plate, a moving mechanism, a plurality of disinfecting mechanisms and two supporting rods; the moving mechanism comprises a first motor, a rotating disc, a drive component and a plurality of moving components; each moving component comprises one driven bevel gear, one lead screw, one moving block and two supporting units; and each disinfecting mechanism comprises one second motor, one disc, one rotating shaft, one bottom disc, one power component and a plurality of ultraviolet lamps. The ultraviolet disinfection device with the regulating function used for the sewage treatment provided by the invention can adjust an inclination degree of each ultraviolet lamp tube through one corresponding disinfection mechanism to make the ultraviolet lamp tubes immersed into sewage to prevent ultraviolet light from irradiating to the outside to affect people health, and the moving mechanism can drive the disinfection mechanisms to rotate to adjust the axial distance between the disinfection mechanism and the rotating disc, so that the ultraviolet radiation range is expanded, full sterilization disinfection of the sewage is realized, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to an ultraviolet sterilizing device with regulating function for sewage treatment. Background technique [0002] Ultraviolet disinfection is an essential part of water treatment. Ultraviolet rays can effectively kill harmful bacteria in sewage and ensure the cleanliness of water bodies. The principle of deep ultraviolet sterilization is to destroy single-celled microorganisms such as cells and viruses through ultraviolet rays to destroy them. The structure of DNA (deoxyribonucleic acid) in the center of life makes bacteria die or lose their ability to reproduce, so as to achieve the purpose of purifying sewage. [0003] In the existing ultraviolet water treatment equipment, the length structure of the ultraviolet lamp tube is fixed. When the height of the top of the ultraviolet lamp tube is higher than the liquid level of the sewage, the ultraviolet rays generated by the pa...

AI Technical Summary

Problems solved by technology

[0003] In the existing ultraviolet water treatment equipment, the length structure of the ultraviolet lamp tube is fixed. When the height of the top of the ultraviolet lamp tube is higher than the liquid level of the sewage, the ultraviolet rays generated by the part of the ultraviolet lamp tube located on the sewage liquid surface are easy to irradiate The outside of the sewage pool is irradiated to the nearby workers. When the ultraviolet radiation is too much, it is easy to cause harm to the human body, which reduces the safety performance of the ultraviolet water treatment equipment. Not only that, due to the poor penetrating ability of the ultraviolet rays, and the suspended impurities in the sewage are relatively high. More, it is easy to block the transmission of ultraviolet rays, which will lead to the inability of ultraviolet rays to purify the sewage in all parts of the pool, which will greatly reduce the disinfection and sterilization capabilities, thereby reducing the practicability of existing ultraviolet water treatment equipment
