Abstract
The utility model relates to a M shape paper folding and filter core for liquid filter, this M shape paper folding is that filter paper obtains through enclosing into the ring form after folding, the folding fold of filter paper is M shape. Compared with the prior art, the utility model discloses increase the area of filter paper to increase the ash volume of holding, extension product life, and on application that can be extensive and the filter core of each different size of a dimensions, include the filter paper of various differences.
Description
Technical field
This utility model relates to liquid filtration art, is specifically related to a kind of M shape for liquid filter and rolls over
Paper and filter element.
Background technology
Liquid filter is indispensable a kind of device on pumped (conveying) medium pipeline, is typically mounted on air relief valve, lets out
The entrance point of pressure valve, Valve for keeping constant water level, fuel pump or miscellaneous equipment, is used for eliminating the impurity in medium, to protect valve
The normal use of door, spraying system and equipment.After fluid entrance is equipped with the filter cylinder of certain specification filter element, its impurity
Being blocked, the filtrate cleaned then is discharged by filter outlet, when needs clean, as long as by dismountable filter cylinder
Take out or change, reload after process, therefore, working service extremely convenient.
In the design of existing liquid filter and utilization, filter element is all star paper folding shape, this star paper folding
Shape filter element is to be encompassed arc-shaped by multiple isometric folds to obtain, as it is shown in figure 1, then by upper and lower end cap
Upper and lower end cap (working of plastics) and filter element by glue bonding or are welded by (metal) by hot plate welding technique.By
Limited in the area of section of the filter cylinder of liquid filter, so using the filter element of star paper folding design can cause area
Waste, thus affect the service life of liquid filter.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of filtering surface is provided
Long-pending big, the M shape paper folding for liquid filter of length in service life and filter element.
The purpose of this utility model can be achieved through the following technical solutions: a kind of M for liquid filter
Shape paper folding, is that filter paper is by surrounding circular obtaining after folding；The folding fold of described filter paper is M shape, uses
M shape paper folding design/technology reaches to maximize the design of filter paper filtering area, extends cleaner service life.
The inner ring of described circular M shape paper folding filter element is formed by the long fold cincture in M shape fold, annulus
The outer ring of the M shape paper folding filter element of shape is replaced around forming with brachy fold successively by the long fold in M shape fold.
1.5～3 times of the length of a length of brachy fold of described long fold.The length of long fold can be according to filter element
Design definition, the length of brachy fold is according to the length matched design of long fold, regularly arranged, the M shape folding of formation
Paper filter element.This size and prior art liquid filter use the equivalently-sized of filter element, thus of the present utility model
M shape paper folding filter element is applicable to existing liquid filter.
Use the liquid filter filter element of above-mentioned M shape paper folding, including upper end cover, bottom end cover, porous central tube and
Filter course, it is characterised in that described filter course is M shape paper folding, these M shape paper folding two ends respectively with upper end cover,
Bottom end cover bonding or welding.
The material of described filter paper is compound filter paper, monolayer filter paper or complete synthesis filter paper material；Described upper end cover
It is metal material or plastic material with bottom end cover.
When upper end cover and bottom end cover are metal material, upper with liquid filter respectively of described M shape paper folding two ends
End cap, bottom end cover bonding or welding.
When upper end cover and bottom end cover are plastic material, by plastic upper end lid, plastics bottom end cover and M shape paper folding heat
The welding of plate Welding is made.
The material of described filter paper can be compound filter paper, monolayer filter paper and complete synthesis filter paper material.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) structure is reliable, and this utility model, only for the purpose of increasing filter area, does not change other ginsengs of filter element
Number such as particle filtration efficiency, on other performances of product without impact.
(2) range is wide, this invention can be widely applied with on the filter element of each different size size, including
Various different filter paper.
(3) increasing service life, this invention can increase the area of filter paper, thus increase appearance ash quantity, reaches to extend
The purpose in product service life.
(4) taking up room little, only need to change indoor design, external shape size can remain unchanged.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of conventional spider paper folding design filter element.
Fig. 2 is M shape paper folding filter element schematic diagram of the present utility model.
Wherein, 1 is long fold, and 2 is brachy fold.
Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment with technical solutions of the utility model is being
Implement under premise, give detailed embodiment and concrete operating process, but protection of the present utility model
Scope is not limited to following embodiment.
Embodiment 1
As in figure 2 it is shown, be a kind of novel M shape paper folding and the filter element of composition thereof, this paper folding is that filter paper passes through folding
Poststack surrounds circular obtaining；The folding fold of described filter paper is M shape, outside the long fold 1 in M shape fold
End replaces around the outer ring forming filter element with the outer end of brachy fold 2, and the inner of long fold 1 is around forming the interior of filter element
Circle.Wherein, the length of long fold 1 is according to filter element design definition, and the length of brachy fold 2 is according to the length of long fold
Matched design, 1.5 times of the length of a length of brachy fold 2 of the longest fold 1, paper folding includes altogether
50 long folds, 50 brachy folds, the filter course of formation is used in the liquid filter of routine, conventional liquid
The filter element of cleaner, including upper end cover, bottom end cover, porous central tube and filter course, wherein in filter course just employing
Stating M shape paper folding, upper end cover and bottom end cover when being metal material, described M shape paper folding two ends are filtered with liquid respectively
The clear upper end cover of device, bottom end cover bonding or welding.
When upper end cover and bottom end cover are plastic material, by plastic upper end lid, plastics bottom end cover and M shape paper folding heat
The welding of plate Welding is made.
Comparative example 1
As it is shown in figure 1, be a kind of traditional star paper folding design filter element, this filter element is that filter paper is by surrounding after folding
Circular obtain；The folding fold of described filter paper is star, i.e. equal by the length of fold, the filter in this comparative example
Core has 76 folds.
It is seen that, as the external diameter that embodiment 1 is identical with the filter element employing of comparative example 1, the M shown in embodiment 1
Shape paper folding filter element is more tight, and filter area is bigger, thus increases appearance ash quantity, reaches to extend product service life
Purpose.
