Abstract
The filter element is one cylinder of wound soft paper band and the paper band layers contact closely. The paper band consists of bleached sulfate broad leafed wood pulp, bleached sulfate coniferous wood pulp, bleached chemical fiber pulp and glue. The filter element has the advantages of high engine oil filtering efficiency, high hydroscopicity, no deformation, no hardening and high dry and wet tension strength. When it is used in automobile, each filter element can serve for a travel distance of 5,000 Km. The said filter element can reduce the exhaust amount of sulfurous acid gas.
Description
The invention belongs to the improvement of oil strainer filter cartridge construction and material.
The filter core of existing oil strainer all is a paper-board material generally, and is horizontal filtration.This filter core exists filter efficiency low, and the moisture in can not filtering machine oil makes engine easily produce and discharge the shortcoming of carcinogenic sulphurous acid gas.
The objective of the invention is to develop a kind of soft paper filter element of multilayer of oil strainer, this filter core is carried out vertical filtration, and adopts the soft paper winding shaping of multilayer.It is the moisture in the filtering machine oil effectively, but also should have high efficiency of filtration.
Filter core of the present invention is made of through being wound in the logical tube of cylinder soft paper tape, is closely contact between every layer of paper tape.The paper that adopts is made up of following composition, and each composition is respectively by weight percentage: bleached sulphate softwood pulp 80～95, BRATSK 1～5, bleaching chemical fiber cotton pulp 2～8.It also includes the glue that accounts for paper pulp gross weight 0.3～1%.The thickness of the soft paper tape of being made by above composition should be at 0.07～0.102mm, and weight is at 14～20g/m
2, largest hole is through being 110～140 μ m, and water absorption should reach 2.5～3 times of paper tape deadweight, does resistance intensity and should reach 2.0～3.0N/15mm, and wet resistance intensity should reach 1.0～1.5N/15mm.
The soft paper filter element of multilayer of the present invention is mainly used in the oil strainer, and it has the machine oil of filtration efficient height, and good water absorption is indeformable, does not harden the advantage that dried wet tensile is high.Be used for just need changing refill one time behind 5000 kilometers of the automobile up strokes.The filter core of doing oil strainer with this refill can reduce the discharge capacity of engine sulphurous acid gas, reduces environmental pollution, favourable health of human body.
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the structural representation of soft paper tape.
Embodiment: present embodiment is made of through being wound in the logical tube 1 of cylinder soft paper tape, is closely contact between logical 1 every layer of paper tape 2 of cylinder.Make the paper tape 2 of filter core and be made up of following composition, each composition is respectively by weight percentage: bleached sulphate softwood pulp 92, BRATSK 3, bleaching chemical fiber cotton pulp 5.It also includes the Polyamide Polyamine Epichlorohydrin Resin that accounts for paper pulp gross weight 0.6%.The thickness of the soft paper tape of being made by above composition is 0.1mm, and weight is 18g/m
2, the maximum diameter of hole is 120 μ m, and water absorption is 2.8 times of paper deadweight, and doing resistance intensity is 2.8N/15mm, and wet resistance intensity is 1.3N/15mm.
