Problems solved by technology

Has the following disadvantages: troublesome operation and maintenance; dosing increases the salinity of the water body, which is more conducive to algae reproduction
The traditional sterilization and disinfection method is chlorine disinfection, but it has the following disadvantages: after excessive dosing, chlorine reacts with pollutants in water to form chlorinated disinfection by-products, which are a large class of chlorine-containing organic substances with complex components, some of which are toxic very big
But there are still the following disadvantages: microwaves are easy to leak, easy to cause harm to the human body, and have certain safety hazards

Embodiment 1

[0025] see Figure 1-5 , a metal shielding net, including a shielding tube 1 and a shielding cover 2; one end of the shielding tube 1 is open, and the other end of the shielding tube 1 is fixedly installed with a shielding cover 2; the shielding tube 1 and the shielding cover 2 are both made of different Made of magnetic 316L stainless steel; the shielding tube 1 and the shielding cover 2 are provided with a number of hexagonal meshes 3 evenly distributed; the length of the diagonal L1 of the hexagonal meshes 3 is 6mm-7mm; the meshes 3 The thickness of the web edge 4 is 0.5-1.5mm, preferably 1mm.

[0026] The shielding tube 1 is equipped with a lamp assembly for emitting ultraviolet rays to remove algae, sterilize and sterilize the fluid; the lamp assembly includes two lamp stands 5 and four lamp tubes 6; the two ends of the four lamp tubes 6 are respectively installed on two On the light frame 5, four mounting holes 7 are provided on the light frame 5 for passing through the...

Embodiment 2

[0029] On the basis of Embodiment 1, the shielding cylinder 1 has a cylindrical structure, the outer diameter of the shielding cylinder 1 is 100mm, and the thickness of the shielding cylinder 1 is 0.3mm.

Embodiment 3

[0031] On the basis of Embodiment 1, the shielding cover 2 has a circular structure, the diameter of the shielding cover 2 is 100 mm, and the thickness of the shielding cover 2 is 0.3 mm.

[0032] The working principle of the present invention is: the present invention rationally designs the material of the metal shielding net and the size of the mesh 3 according to the wavelengths and different orientations of microwaves and ultraviolet rays. And through the simulation experiment measurement, the spectrum outside the metal shielding net only contains ultraviolet wavelengths, which proves that the metal shielding net can shield microwaves.

Abstract

The invention discloses a metal shielding net. The metal shielding net comprises a shielding cylinder and a shielding cover, wherein one end of the shielding cylinder is open, and the shielding coveris fixed at the other end of the shielding cylinder; both the shielding cylinder and the shielding cover are made of a non-magnetic metal material; a plurality of hexagonal meshes are uniformly distributed in each of the shielding cylinder and the shielding cover; diagonal lines of the hexagonal meshes are 6-7 mm long, and edges of the meshes are 0.5-1.5 mm thick. The metal shielding net has reasonable design and simple structure, and can be used in a quartz tube in a resonant cavity of microwave fluid algae removal, sterilization and disinfection equipment; the design size and material of theshielding net cannot only ensure smooth activation of electrodeless lamp tubes by microwaves and enable ultraviolet rays emitted by the electrodeless lamp tubes to penetrate the metal shielding net to perform alga removal, sterilization and disinfection on fluid, but also ensure the microwaves do not leak out, and accordingly, harm to human bodies is avoided, and use safety is ensured.

Description

technical field [0001] The invention relates to a shielding net, in particular to a metal shielding net. Background technique [0002] In the common process of circulating water treatment, it is necessary to remove algae and sterilize the water body. The traditional method of algae removal is to filter by dosing, that is, to add flocculant. It has the following disadvantages: operation and maintenance are troublesome; dosing increases the salinity of the water body, which is more conducive to algae reproduction. The traditional sterilization and disinfection method is chlorine disinfection, but it has the following disadvantages: after excessive dosing, chlorine reacts with pollutants in water to form chlorinated disinfection by-products, which are a large class of chlorine-containing organic substances with complex components, some of which are toxic very big. [0003] There are some microwave fluid algae removal, sterilization and disinfection equipment on the market at...
