Embodiment Construction

[0010] Such as figure 1 As shown, the composite filter environmental protection filter element includes a filter element body, an upper end cover sealingly connected to the upper side of the filter element body, and a lower end cover sealingly connected to the lower side of the filter element body. The filter element body includes a central tube 1 and a filter material arranged on the outer peripheral side of the central tube, and the filter material includes a first filter material layer 2 with the function of filtering impurities and a second filter material layer 3 with the function of oil-water separation.

[0011] Wherein, the material of the first filter material layer is fiber composite filter paper, the surface of which is processed by a melt-blown process to form a fiber filament composite layer on the surface of the filter material, which can achieve good impurity filtering ability.

[0012] The material of the second filter material layer is non-woven fabric, and th...

Abstract

The invention discloses a composite filtration environment-friendly filter element, comprising a filter element body, an upper end cover hermetically connected to the top of the filter element body and a lower end cover hermetically connected to the bottom of the filter element body; the filter element body comprises a center tube and a filter material arranged on the periphery of the center tube, the filter material includes a first filter material layer having impurity filtering function and a second filter material layer having oil-water separating function, the first filter material layer is arranged around the peripheral wall of the center tube and is peripherally of wavy star structure, and the second filter material layer is arranged around the peripheral wall of the first filter material layer and is of multilayer tangling structure. The composite filtration environment-friendly filter element has efficient filtering capacity and high dust-bearing capacity as well as oil-water separating capacity, has improved dust-bearing capacity and has high filtering efficiency and long service life.

Description

technical field [0001] The present invention relates to filters, in particular to filter elements. Background technique [0002] The structure of the traditional filter element is generally a single roll-type or origami-type structure, which can only perform the function of filtering impurities or separating oil and water. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compound filter environmental protection filter element with compound filter function. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: a composite filter environmental protection filter element, including a filter element body, an upper end cover sealingly connected to the upper side of the filter element body, and a lower end cover sealingly connected to the lower side of the filter element body, the filter element body includes a center tube and the filter materia...
