Abstract
The utility model relates to an industrial filter element whose filter precision achieves the micron dimension. A filter layer which is coiled to be cylindrical is arranged between an internal central pipe bracket and an external central pipe bracket of the filter element of the filter. The internal and the external central pipe brackets are cylinders on which a plurality of holes are densely distributed. An accumulative layer which accumulates the water contained in the oil liquid is arranged on the outer side of the external central pipe. The external side of the collecting layer is a protective layer. Both ends of the filter element are buckled with end caps. A glass fiber filter paper layer whose filter precision is micron dimension is adopted as the substrate of the filter layer. The protective is composed of a composite nonwoven cloth and a protective net. The substrate of the accumulative layer is a glass fiber mat. A nonwoven cloth is arranged on the inner side of the glass fiber mat. The outer side of the glass fiber mat is bundled on the external central pipe and a cotton sleeve is nested on the surface of the glass fiber mat. The utility model is applicable to the working conditions including high alkali concentration, high work pressure and high-temperature oil liquid, guaranteeing no deformation and no breakdown of the filter materials.
Description
Technical field
The utility model relates to a kind of filtration that is used for fluid liquid, particularly relates to a kind of industrial filter element.
Background technology
Existing filter element has a lot of schemes.For example, Chinese patent 00110305.9 short-staple filter material and filter core, 89108986.1 synthetic fiber filter materials and 96107186.9 filter cores.These filter filtering accuracies are not high, adopt the filter core of this material of 80~120 order fine powders to be difficult to the micron-sized impurity of filtering in the scheme of Chinese patent 00110305.9, ubiquity is alkaline-resisting, heatproof, withstand voltage properties deficiency, high temperature, high pressure, high dense contain to use in the alkali fluid destroyed the forfeiture filtering function very soon.
Summary of the invention
The purpose of this utility model is to propose the filter element that a kind of filtering accuracy reaches micron dimension.
Filter element of the present utility model is to realize like this.In filter element, be filled with the filter course that is rolled into cartridge type between the exterior central tube support, interior exterior central tube for the perforate of gathering or stainless steel, or the alkaline-resisting processing through the surface (plastic-blasting, plating, japanning) metal or plastic cylinder, pleated or the phozy of filter course, the exterior central tube outside be can coalescent fluid in the coalescent layer used of moisture content, the coalescent layer outside is protective layer, the filter core two ends are buckled with end cap, it is characterized in that: described filter course is a matrix with filtering accuracy micron order glass fiber filter paper layer, the protective layer that inside and outside compound nonwoven cloth, nylon (polyester) net are formed; Described water droplets coalescence layer is a matrix with the glass mat, the inboard lining of glass mat nonwoven, and the outside is bundled on the exterior central tube with glass fiber plastic-blasting net, outermost cover acrylic fibers (terylene, polypropylene fibre) cotton-padded covering.
Filter element of the present utility model can contain in alkali concn, high workload pressure, the high-temperature oil liquid at height works, and filter material is indeformable, does not puncture.
