Punch forming over-current ultraviolet sterilizer and manufacturing process for sterilization device of punch forming over-current ultraviolet sterilizer

Abstract

The invention provides a punch forming over-current ultraviolet sterilizer which comprises a sterilization device and a distribution box, wherein the sterilization device comprises a main body provided with a water inlet and a water outlet for mounting of a water inlet device and a water outlet device and ultraviolet lamp tube sleeves; ends in structural symmetry are arranged at the two ends of the main body; the ends are punch forming ends; a plurality of benchmark stages uniformly distributed are arranged at the ends; a through hole is formed in each benchmark stage; a wire end used for arrangement of a sealing sleeve is arranged on each benchmark stage through welding; the ultraviolet lamp tube sleeves are arranged on the two benchmark stages, the ends of which are symmetrical; the distribution box is connected with the ultraviolet lamp tube sleeves and arranged below the main body through a barrel bracket; a manufacturing process for the sterilization device of the sterilizer comprises the following steps: primary punching and secondary punching of the ends, spinning forming of the ends, punch forming of the water inlet and the water outlet, welding, assembling and the like. Through the design, batch production of the sterilizer is realized, the quality of the sterilizer is improved, the production cost is reduced and later maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a stamping forming over-flow ultraviolet sterilizer and a manufacturing process of the sterilizing device. Background technique [0002] Ultraviolet sterilizers are widely used and have a high value in water treatment. It destroys and changes the DNA (deoxyribonucleic acid) structure of microorganisms through ultraviolet light irradiation, so that the bacteria die immediately or cannot reproduce offspring to achieve the purpose of sterilization . It is UVC ultraviolet rays that really have a bactericidal effect, because C-band ultraviolet rays are easily absorbed by the DNA of organisms, especially ultraviolet rays around 253.7nm are the best. Ultraviolet sterilizer is a purely physical disinfection method, which has the advantages of simplicity, convenience, broad spectrum and high efficiency, no secondary pollution, easy management and automation. With the in...

AI Technical Summary

Problems solved by technology

[0004] 1. In the production of the end of the ultraviolet sterilizer in the current technology, holes must be drilled on the solitary head first, and then the wire head is welded to fix the quartz sleeve and the sealing kit. The disadvantages: the positioning accuracy of the drilling is poor, and the efficiency is very low. In addition, the wire head must be ground according to the arc of the head before welding, which is difficult to produce, and the efficiency is low and the cost is high. In addition, because the welding part of the welding part has an irregular arc surface, automatic welding equipment cannot be used for welding, and the welding quality cannot be guaranteed;

[0005] 2. The water inlet and outlet need to be ground and cut before they can be welded together with the main body. Manual welding and grinding can only be used, the production efficiency is low, and the welding quality cannot be guaranteed. In addition, subsequent grinding and polishing are required after welding, and the manufacturing process is cumbersome;

[0006] 3. The sealing kit is prone to seizure, making it impossible to separate the sealing kit from the main body until it is scrapped;

[0007] 4. The distribution box is formed by welding and grinding in pieces, and the manufacturing precision is very low, which makes the equipment components not universal and interchangeable, which is not conducive to later maintenance and high maintenance costs
