Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention.
As shown in fig. 1-2, a compound glass fiber wide flow channel high-pollutant-receiving high-retention-rate folding filter element comprises a framework 11, an end cover 10 and a filter material 2, wherein the end cover 10 is arranged at two ends of the framework, the framework comprises an outer framework 1 and an inner framework 5, the filter material is distributed between the inner framework 5 and the outer framework 1 in a surrounding mode through a folding structure, the filter material sequentially comprises an outer support layer 6, an outer filter membrane 7, an inner filter membrane 8 and an inner support layer 9, the filter material is located in the framework to form an outer filter element flow channel 3 and an inner filter element flow channel 4, the outer filter membrane is a large-aperture filter material, and the inner filter membrane is a small-aperture filter material.
As shown in figure 3 of the drawings,
the outer supporting layer adopts rhombic hole coarse grid cloth with the thickness of 0.6mm and the thickness of 5mm x 3mm, so that an outer flow passage can be effectively widened.
The inner supporting layer is 0.3mm thick and 1mm x 1mm square hole fine grids, so that the inner flow channel can be prevented from being too tight to cause bonding, and the filter element is blocked.
The outer layer adopts 10 mu m glass fiber filter membrane, can adsorb and hold back large aperture particle impurity, can improve the pollutant carrying capacity greatly, and ensure that the inner layer filter membrane is difficult to be blocked by large aperture particle impurity.
The inner layer adopts a 1 mu m glass fiber filter membrane, can adsorb and retain small-aperture particle impurities, and is matched with the outer layer of 10 mu m filter membrane to form gradient compounding and layered retention, so that the retention efficiency of the filter element is greatly improved.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
