The technical scheme adopted for realizing the technical purpose of the invention is as follows: the electromagnetic sewage filtering system comprises a filtering pipe, wherein a front filtering net and a rear filtering net are arranged in the filtering pipe; the front and rear filter screens are made of soft iron wires; mesh nodes of the front filter screen and the rear filter screen are not fixed, so that the soft iron wires can move transversely; the filter tube is internally provided with a front annular plate and a rear annular plate which extend inwards from the inner wall of the filter tube in the radial direction, and the front annular plate and the rear annular plate are respectively clung to the front filter screen and the rear filter screen; a strip-shaped electromagnet is arranged on the central connecting line of the front filter screen and the rear filter screen, and the front filter screen and the rear filter screen are symmetrical about the middle section of the electromagnet; the front sides of the front filter screen and the rear filter screen are respectively provided with a front pressure gauge and a rear pressure gauge; the front pressure gauge, the rear pressure gauge and the electromagnet are coupled to a controller outside the filter pipe.
Preferably, the controller operates as follows: and gradually increasing the exciting current of the electromagnet from zero until the pressure difference between the front pressure gauge and the rear pressure gauge reaches a preset value.
Preferably, the front filter screen and the rear filter screen are both horn-shaped, and the horn mouths face to the outer ends of the electromagnets, so that soft iron wires forming the filter screens can move towards the central area of the filter screens more easily; furthermore, the circumferential distribution positions of the front pressure gauge and the rear pressure gauge on the front filter screen and the rear filter screen have a 180-degree difference with respect to a central connecting line of the front filter screen and the rear filter screen, so that the front pressure gauge and the rear pressure gauge have consistent inclined pressure surfaces.
Preferably, the front annular plate and the rear annular plate are respectively arranged at the rear sides of the front filter screen and the rear filter screen, so that the front filter screen is enabled to press the front annular plate, and the rear filter screen is enabled to press the rear annular plate under the action of water flow.
The invention has the beneficial effects that: when the electromagnetic sewage filtering system works, the soft iron wires of the front filter screen and the rear filter screen are magnetized due to the electrification of the electromagnet, so that the soft iron wires are mutually attracted and are tightly squeezed towards the center of the filter screens, and meshes are reduced; when the exciting current of the electromagnet is larger, the squeezing degree is more obvious, and the meshes are smaller; after the meshes at the centers of the front filter screen and the rear filter screen are reduced, a soft iron wire sparse area is formed at the periphery of the front filter screen and the rear filter screen, and the sparse area is shielded by the front annular plate and the rear annular plate; on the other hand, when the pressure difference between the front pressure gauge and the rear pressure gauge is smaller, the particle impurities on the surfaces of the front filter screen and the rear filter screen are equivalent, the resistance to water flow is equivalent, the mesh is overlarge, and basically no filtering effect exists; when the pressure difference reaches a preset value, the obvious filtering effect is formed on the front filter screen; at the moment, the filtering effect is guaranteed, and the filtering speed is also guaranteed.

Detailed Description
The invention is further illustrated with reference to the following figures and examples:
in the first embodiment shown in fig. 1 and 2, the electromagnetic sewage filtering system comprises a filtering pipe 1, wherein a front filtering net 21 and a rear filtering net 31 in a circular and planar shape are arranged inside the filtering pipe 1; the front and rear filter screens 21 and 31 are made of soft iron wires; mesh nodes of the front filter screen and the rear filter screen are not fixed, each soft iron wire is only fixed at the end part, and the middle part can move transversely (the soft iron wires can deform); the filter tube 1 is also internally provided with a front annular plate 22 and a rear annular plate 32 which extend inwards from the inner wall of the filter tube in the radial direction, and the front annular plate 22 and the rear annular plate 32 are respectively clung to the front filter screen 21 and the rear filter screen 31; a strip-shaped electromagnet 4 is arranged on the central connecting line of the front filter screen 21 and the rear filter screen 31, and the front filter screen 21 and the rear filter screen 31 are symmetrical about the middle section of the electromagnet 4; the front sides of the front filter screen 21 and the rear filter screen 31 are respectively provided with a front pressure gauge 23 and a rear pressure gauge 33; the front pressure gauge 23, the rear pressure gauge 33 and the electromagnet 4 are commonly coupled to a controller (not shown) outside the filter pipe 1.
In the electromagnetic sewage filtering system, the front annular plate 22 and the rear annular plate 32 are respectively arranged at the rear sides of the front filter screen 21 and the rear filter screen 31, so that the front filter screen 21 is ensured to compress the front annular plate 22 and the rear filter screen 31 is ensured to compress the rear annular plate 32 under the action of water flow, and a water body is prevented from flowing through a peripheral sparse area of the filter screen from a gap between the annular plate and the filter screen.
The controller operates as follows: the exciting current of the electromagnet 4 is gradually increased from zero until the pressure difference between the front pressure gauge 23 and the rear pressure gauge 33 reaches a predetermined value.
In the second embodiment shown in fig. 3, different from the first embodiment, the front and rear filter screens 21 and 31 are both trumpet-shaped, and the trumpet-shaped mouths face the outer ends of the electromagnets 4, so that the soft iron wires forming the filter screens can move towards the central area of the filter screens more easily; in addition, the circumferential distribution positions of the front pressure gauge 23 and the rear pressure gauge 33 on the front filter screen 21 and the rear filter screen 31 are different by 180 degrees with respect to the central connecting line of the front filter screen 21 and the rear filter screen 31, so that the front pressure gauge 23 and the rear pressure gauge 33 have uniform inclined pressure receiving surfaces.
When the electromagnetic sewage filtering system works, the electromagnet 4 is electrified, so that the soft iron wires of the front filtering net 21 and the rear filtering net 31 are magnetized, the soft iron wires attract each other and are squeezed to the center of the filtering net, and meshes are reduced; when the exciting current of the electromagnet 4 is larger, the squeezing degree is more obvious, and the meshes are smaller; after the meshes at the centers of the front filter screen 21 and the rear filter screen 31 are reduced, a soft iron wire sparse area is formed at the periphery, and the sparse area is shielded by the front annular plate 22 and the rear annular plate 32; on the other hand, when the pressure difference between the front pressure gauge 23 and the rear pressure gauge 33 is small, it means that the particle impurities on the surfaces of the front filter screen 21 and the rear filter screen 31 are equivalent, the resistance to water flow is equivalent, which means that the meshes are too large and basically have no filtering effect, and when the pressure difference is gradually increased, it means that the particle impurities on the surface of the front filter screen 21 are gradually increased and the meshes are gradually reduced to a proper size; until the pressure difference reaches a predetermined value, indicating that the front filter screen 21 has formed a significant filtering effect; at the moment, the filtering effect is guaranteed, and the filtering speed is also guaranteed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
