Conventional filter screens generally consist of a frame, filter paper, and hot melt adhesive. In order to improve the dust holding capacity, the filter paper is generally folded, the area is increased, so that the dust holding capacity is improved, and the filter material in the filter paper, such as melt-blown cloth, is generally soft in texture and cannot be folded and shaped, so that a framework layer is required to be compounded, the filter paper is formed, and the cost of the filter screen is increased by the process of compounding the framework layer. The filter paper also needs to be fixed and maintained in a folded shape by using a hot melt adhesive, and excessive use of the hot melt adhesive also causes environmental problems. Furthermore, the frame, the filter paper and the hot melt adhesive of the traditional filter screen are integrally formed, and are not repeatedly installed and detached, and when the filter screen is replaced, the whole filter screen is required to be replaced, so that the problems of high maintenance cost and resource waste of the filter screen are further caused.
