Composite spunlace filter material with self-cleaning function and preparation method thereof

Abstract

The application discloses a composite spunlace filter material with a self-cleaning function and a preparation method thereof, and belongs to the technical field of industrial filtration and dust removal. The composite spunlace filter material comprises a filter cylinder body, the filter cylinder body comprises an upper end cover, a lower end cover, a metal support net and a composite spunlace filter material wrapped outside the metal support net, the upper end cover and the lower end cover are respectively sealed at the axial two ends of the metal support net and the composite spunlace filter material, and a mounting ring is rotatably mounted at the bottom of the lower end cover. The application can automatically trigger a mechanical dust removal action when the surface dust of the spunlace filter material causes the filtration resistance to increase and the internal negative pressure reaches a preset threshold value by pure mechanical linkage between the internal negative pressure change of the filter cylinder and the rotating mechanism. The rotating mechanism drives the mounting ring to drive the stirring assembly to rotate around the outer surface of the composite spunlace filter material, directly disturbs the peak part of the filter material wrinkle, and can shake off the dust. No additional elements such as a matching control system are needed, and the adaptability and operation stability of the composite spunlace filter material to working condition fluctuations are improved.
