Abstract

The utility model discloses plant fiber composite filter paper which comprises an outer layer, a filter layer and a supporting layer, wherein the outer layer, the filter layer and the supporting layer are sequentially attached by glue, the outer layer is provided with a plurality of prismatic filter holes, the filter layer is provided with hourglass filter holes, the supporting layer is a coating paper layer made of cotton pulp fibers, the filter paper adopts a multilayer structure, improves the filtering effect, can quickly absorb engine fuel through the prismatic table filtering holes on the outer layer, the hour glass-shaped filtering holes arranged on the filtering layer can increase the time for the fuel oil to stay in the filtering layer, so that the filtering is more sufficient, the fuel oil can quickly enter the supporting layer after being filtered, the supporting layer is made of cotton pulp fibers, the cotton pulp fibers are more slender than wood pulp fibers, gaps among the fibers are smaller, so that the pore diameter of the formed pores is smaller, the more the formed pores are, the filtering area is increased, and the filtering effect is further improved.

Description

Plant fiber composite filter paper

Technical Field

The utility model relates to the technical field of filter paper, in particular to plant fiber composite filter paper.

Background

The fuel filter paper is a key component in a fuel filter of an automobile engine, determines the performance of the fuel filter, and is usually a paper filter layer made of common wood pulp as a main component.

However, the filter paper made of common wood pulp has poor water resistance, is easy to deform after being soaked for a long time, has low strength, small filter area and poor filter effect.

SUMMERY OF THE UTILITY MODEL

The utility model provides plant fiber composite filter paper to solve the technical problems in the background technology.

The technical problem of the utility model is solved by the following technical scheme:

the utility model provides a compound filter paper of plant fiber, its characterized in that includes skin, filter layer, supporting layer, skin, filter layer, supporting layer loop through the glue laminating, a plurality of prismoid form filtration pores have been seted up to the skin, hourglass form filtration pore has been seted up to the filter layer, the coating paper layer of supporting layer for adopting the cotton pulp fiber to make, be provided with the enhancement layer between skin and filter layer, filter layer and the supporting layer.

Preferably, the outer layer is a spunbond nonwoven layer.

Preferably, the filter layer is a polyester melt-blown fabric layer.

Preferably, activated carbon layers are arranged above and below the filter layer and between the reinforcing layers.

Preferably, the reinforcing layer is a abaca fiber layer.

The utility model has the beneficial effects that: this filter paper adopts multilayer structure, the filtering effect is improved, can absorb engine fuel fast through the terrace with edge filtration pore on the skin, hourglass form filtration pore through setting up at the filter layer can increase the time that the fuel stops at the filter layer, make and filter more abundant, can enter into the supporting layer fast after having filtered, the supporting layer adopts cotton pulp fiber to make, cotton pulp fiber is than wood pulp fiber more slender, the clearance between the fibre can be littleer, thereby the aperture that forms the hole will be littleer, the hole of formation will be more, increase filter area, thereby further promote the filter effect.

Detailed Description

The following description is only a preferred embodiment of the present invention, and the protection scope is not limited to the embodiment, and any technical solution that falls under the idea of the present invention should fall within the protection scope of the present invention. It should also be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model.

See fig. 1-2, a plant fiber composite filter paper, a serial communication port, including outer 1, filter layer 2, supporting layer 3, outer 1, filter layer 2, supporting layer 3 loops through the glue laminating, a plurality of prismoid form filtration pores 6 have been seted up to outer 1, hourglass form filtration pore 7 has been seted up to filter layer 2, supporting layer 3 is the coating paper layer that adopts the cotton pulp fiber to make, outer 1 and filter layer 2, be provided with enhancement layer 4 between filter layer 2 and the supporting layer 3, outer 1 is the spunbonded nonwoven layer, filter layer 2 is the polyester melt-blown cloth layer, all be provided with activated carbon layer 5 between filter layer 2 top and below and the enhancement layer 4, activated carbon layer 5 can further promote filterable effect, enhancement layer 4 is the abaca fibrous layer, the abaca fibre is slender, tough and tough can add the intensity of this filter paper, and water-fast soaks.

Outer 1 can prevent 2 surface balling-ups of filter layer for spunbonded nonwoven layer, thereby influence the filter effect, and a plurality of prismoid form filtration pore 6 has, can absorb engine fuel fast, filter layer 2 is polyester meltblown cloth, polyester meltblown cloth holds the dirt rate height, it is good to engine fuel filter effect, hourglass form filtration pore 7 that sets up in the filter layer 2 can increase when long engine fuel's filtration, thereby make the filter effect better, the fuel after the filtration can be quick enters into next floor, the length of the first half section of this hourglass form filtration pore 7 is greater than the second half section, supporting layer 3 adopts the cotton pulp fibre to make, the cotton pulp fibre is more long and thin than the wood pulp fibre mutually, the clearance between the fibre can be littleer, thereby the aperture that forms the hole will be littleer, the hole that forms will be more, increase filter area, thereby further promote the filter effect.
