Abstract
The utility model discloses a filter element which mainly comprises a porous center pipe, a filter layer wrapped outside the porous center pipe and a casing sheathed outside the filter layer, whereinone end of the casing is provided with an upper end cap and the other end thereof is provided with a lower end cap, and a secondary filter layer is further arranged between the filter layer and the porous center pipe. In the filtering process of product, the filter layer filters off the majority of impurities and the secondary filter layer only filters off fiber falling from nonwoven fabric at thedownstream of the filter layer or other impurities penetrating through the filter layer, thus having no influence on the service life of the filter element and effectively preventing impurities frombeing mixed with the filtrate.
Description
Technical field
The utility model relates to a kind of filter core.
Background technology
Its structure of existing cylindrical filter cartridge generally is made up of plastic skeleton and filter course, comprises plug, upper end cover, shell, porous central tube, bottom end cover, filter course, fin, seal etc.Assembling process is as follows: earlier filter course is wrapped up or is enclosed within outside the porous central tube, again with outer cover suit outside filter course, close with end cap up and down molten (glue) respectively at its two ends afterwards, last end and fin melt (gluing) and close, the other end closes with the plug molten (gluing) of band seal, forms a cylindrical filter cartridge.
Wherein mainly to act on be the protection filter course to shell, and more solid and filtering accuracy is thicker for filter course, shell also can omit.
Filtered fluid generally by shell process filter course, enters after the filtration in the porous central tube, is flowed out by porous central tube again.
Filter course has folding cartridge type, twines (volume) around cartridge type etc.Folding barrel type filtering layer is made up of filter membrane (or filter material) and the nonwoven fabric that is wrapped in filter membrane (or filter material) up and down.Nonwoven fabric mainly plays diaphragm (or filter material) generally by fibrous, also plays the effect of water conservancy diversion simultaneously.In the filter process, under the effect of current, the fiber on the nonwoven fabric of downstream and other impurity easily come off.The fiber impurity that the downstream nonwoven fabric comes off etc. is directly fallen in the porous central tube, flows in the finished fluid, causes and contains impurity in the filtered fluid, influences product quality.Twine (volume) and also form, have above defective equally by fibrous filter one class material around barrel type filtering layer great majority.
Summary of the invention
The utility model provides a kind of novel filter core, at existing folding cartridge type and twine (volume) and improved around cylindrical filter cartridge etc., avoids filtered fluid to sneak into impurity.
A kind of filter core mainly comprises porous central tube, is wrapped in the outer filter course of porous central tube, and filter course is with shell outward, and shell one end is provided with upper end cover, and the other end is provided with bottom end cover, also is provided with time filter course between filter course and porous central tube.
The utility model increases filtration together in the filter course downstream, claim time filter course.The filtering accuracy of inferior filter course can be equal to the filtering accuracy of filter course or be approaching, and the purpose that can reach the impurity such as fiber that separation (blocking) filter course comes off gets final product.
Inferior filter course is general selects to be difficult for to have filter material that fiber impurity comes off for well, as filter screen, and filter materials such as miillpore filter.
Inferior filter course can be wrapped on the external diameter of porous central tube, and with edge molten (gluing) envelope, two of inferior filter course also should be sealed with poriferous circular external diameter of pipe two molten (gluing) in case of necessity behind the parcel.
In the product filter process, filter course is with most impurity filterings, inferior filter course is only born the impurity such as fiber that filtering filter course downstream nonwoven fabric comes off, so the utility model scheme can not have influence on the life-span of filter core, and can effectively prevent sneaking into of impurity in the filtered fluid.

The specific embodiment
Be described further below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of existing filter core, comprise porous central tube 6, be wrapped in the outer filter course 5 of porous central tube, the filter course 5 outer shells 4 that are with, close with upper end cover 3 and bottom end cover 7 molten (gluing) respectively at its two ends, last upper end cover 3 closes with the plug 1 molten (glue) of band o RunddichtringO 2, bottom end cover 7 and fin 8 melt (gluing) and close, form a cylindrical filter cartridge.
Fig. 2 is the structural representation of the utility model filter core, compared to Figure 1, set up inferior filter course 9 between porous central tube 6 and filter course 5, the aperture of inferior filter course 9 equals or near the aperture of filter course 5, prevent the fiber that filter course 5 comes off, or other sees through the impurity of filter course 5.
The setting of inferior filter course 9 as shown in Figure 3, inferior filter course 9 is wrapped on the external diameter of porous central tube 6, behind the parcel edge molten (gluing) is closed, in case of necessity, inferior filter course 9 two also should be sealed with 6 liang of first melts of porous central tube (gluing).
During filtration, filtered fluid filters through time filter course 9 after filtering through filtering layer 5 again, enters in the porous central tube 6, is flowed out by porous central tube 6 again.
Claims (2)
1, a kind of filter core, mainly comprise porous central tube (6), be wrapped in the outer filter course (5) of porous central tube (6), the outer shell (4) that is with of filter course (5), shell (4) one ends are provided with upper end cover (3), the other end is provided with bottom end cover (7), it is characterized in that: be provided with time filter course (9) between described filter course (5) and the porous central tube (6).
2, filter core as claimed in claim 1, it is characterized in that: described filter course (9) is wrapped on the external diameter of porous central tube (6), behind the parcel with edge sealing by fusing or seal, two sealing by fusing or the seal of inferior filter course (9) two and porous central tube (6) external diameter.
