Anti-blocking electromagnetic filter device
Technical Field
The invention relates to the technical field of filtering devices, in particular to an anti-blocking electromagnetic filter device.
Background
Electromagnetic filters operate on the principle of a filtration device that uses the action of electromagnetic forces to remove magnetic oxides from water. The electromagnetic filter adsorbs and removes magnetic oxides in water by using electromagnetic force. Such filters typically comprise ferromagnetic material and blocking screens, whereby the magnetic oxide is attracted to the magnetic material as the water stream containing the magnetic oxide passes through, thereby effecting separation and purification. The electromagnetic filter is suitable for various application scenes including but not limited to water treatment, chemical production and the like, and can effectively remove magnetic impurities in water and ensure the purity of water quality or production flow. Furthermore, the principle of operation of magnetic filters is based mainly on magnetic adsorption and fluid dynamics. The inside of the filter comprises a ferromagnetic material and a blocking filter screen, and when a fluid containing ferromagnetic impurities passes through the filter screen, the impurities are adsorbed on the magnetic material, so that separation and purification are realized. Some magnetic filters also use turbulent flow to change the speed and pressure of water and release bubbles, which accumulate on the metal mesh and separate impurities from the fluid by gravity.
Through retrieving chinese patent publication No. CN218742493U, an electromagnetic filter for a pipeline is disclosed, the electromagnetic filter adopts an electromagnetic absorber to absorb magnetic oxides in a water body, but when the electromagnetic filter is used for a long time, as the magnetic oxides absorbed on the surface of the electromagnetic absorber accumulate more, the thickness of the magnetic oxides absorbed on the surface of the electromagnetic absorber is larger, thereby affecting the adsorption capacity of the electromagnetic absorber, and meanwhile, the magnetic oxides are directly attached to a filter screen without being absorbed by the electromagnetic absorber, which can cause the surface of the filter screen to be blocked, if the electromagnetic filter is cleaned by means of manual operation, the whole pipeline needs to be closed for liquid circulation, which causes inconvenience, therefore, an electromagnetic filter device capable of reducing the cleaning period of the electromagnetic filter and avoiding the blocking phenomenon of the filter screen is needed.
