Detailed Description
The invention is further described with reference to the following description of the drawings and specific embodiments.
The inventor finds that: in the existing water treatment process, the water is generally treated by carrying out multi-layer filtration through a filter screen, so that the high-efficiency filtration effect is achieved, or the filter screen is wrapped into a filter element for filtration. However, the existing filter screens are two-dimensional screens, the overlapping degree between the screen wires is large when the two-dimensional screens are woven in a crossed mode, the actual filtering area perpendicular to the water flow is much smaller than the calculated filtering area, and the actual filtering effect is far lower than the expected filtering effect.
As shown in fig. 1, a filter screen has the following structure, which specifically includes: a first wire 4 and a second wire 5. The number of the first net wires 4 and the second net wires 5 is several and the same. In order to increase the porosity and the specific surface area of the filter screen, the mesh diameters of the first mesh wire and the second mesh wire are not equal, and the weaving structure of the first mesh wire and the second mesh wire is as follows:
a part of the first mesh wires 4 and the second mesh wires 5 are equidistantly and alternately distributed in the X axis direction, the rest of the first mesh wires 4 and the rest of the second mesh wires 5 are equidistantly and alternately distributed in the Y axis direction, the first mesh wires in the Y axis direction sequentially pass through the first mesh wires and the second mesh wires in the X axis direction in a sine manner, and the second mesh wires in the Y axis direction sequentially pass through the first mesh wires and the second mesh wires in the X axis direction in a cosine manner, as shown in fig. 2.
As shown in fig. 12, the mesh diameter of the first mesh is set to R1, the mesh diameter of the second mesh is set to R2, and the following relationship is satisfied between R1 and R2:
R1＞0.3mm，
；
defining the crossing angle of the first mesh wire and the second mesh wire as a dihedral angle
The second mesh wire is arranged at the crossing angle of the first mesh wire and is a dihedral angle
，
Then the process of the first step is carried out,
，
wherein d is the distance between the first mesh and the second mesh, and the value of d should satisfy
、
The value range of (A) is between 5 and 15 degrees.
The crossing angle between the first screen wire and the second screen wire in the filter screen meeting the conditions is 5-15 degrees, so that the strength requirement can be met, the filtering area of actual water flow can be ensured to be the maximum, and the filtering efficiency is the highest. If the crossing angle between the first net wire and the second net wire exceeds 15 degrees, the degree of contact between the first net wire and the second net wire is large, the bending degree is increased, and the effective filtering area is reduced. Meanwhile, compared with the filter screen in the prior art, the filter screen has better flexibility, and the intersection among different screen diameters forms an indispensable elastic space, so that the filter screen is suitable for superposition of any shape and has a wide application range. The problem that a filter screen in the prior art is too hard is solved.
The filter screen is used in the sewage device below, and is specifically represented as follows: at present, in the water treatment, in order to improve the water treatment intensity and increase the cleanliness of the filtered water, multi-stage filtration is adopted, but no matter how many stages of filtration are adopted, filters in a first stage filtration unit and a second stage filtration unit need to be subjected to solid-liquid separation, and are like silt, particles and the like. Therefore, the inventor makes the following improvements on the existing sewage treatment device based on the filter screen:

In a further embodiment, the separating mesh 106 is a circular truncated cone structure, and the diameter of the separating mesh 106 gradually decreases from the water inlet 102 to the sewage outlet. I.e. the distance between the separating net 106 and the first cylinder 101 increases gradually from the inlet 102 to the first outlet, so that the water flow tends to flow more towards the first outlet for discharge, considering the decrease in pressure.
In a further embodiment, the secondary filtration unit 2 comprises: the adsorption device comprises a second cylinder 201, wherein a first adsorption cavity 202 and a second adsorption cavity 203 are sequentially arranged in the second cylinder 201 from top to bottom.

The vertical section of the diversion shell 206 is in an inverted cone shape, so that the contact area of water with the filter membrane is increased, the filtering time of the water is prolonged, and the filtering strength is enhanced under the extrusion of gravity and pressure. One or more of aluminosilicate adsorbent and active carbon are filled on the filter membrane. The filter screen is the multilayer, the external diameter of filter screen the trend of change with the trend of change of the internal diameter of water conservancy diversion casing is unanimous, the filter screen passes through the clamp and closely fixes the inside of water conservancy diversion casing.
