Description
Technical field
Filter bag technical field is the utility model is related to, more particularly to a kind of multistage filtering available for duplex strainer is filtered
Bag.
Background technology
The filter bag of traditional duplex strainer only has single-stage filtering, and all impurity is all concentrated on one layer of filter layer, filter
Bag burden weight, easily blocks filtering layer, poor filtration effect, therefore, it is necessary to technically make improvements.
Utility model content
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of multistage filtering available for duplex strainer
Filter bag.
The utility model to achieve the above object, using following technical scheme：
A kind of described multistage filtering filter bag available for duplex strainer, including bag body, it is characterised in that bag in vivo by
Detachable successively under up to be fixed with one-level filtering layer, two level filtering layer, one-level filtering layer, two level filtering layer, the mesh of bag body subtract successively
It is small, the annular bucket neck that section is in reverse U shape shape is provided with the outside of the open top end of bag body.
Preferably, the internal wall of bag is from top to bottom fixed with the circular neck that two sections are in positive U-shaped, one-level successively
Filtering layer, the edge of two level filtering layer are provided with the circular buckle that section is in reverse U shape shape, and the buckle at two level filtering layer edge is fastened on down
In portion's neck, the external diameter of the buckle at two level filtering layer edge is less than the internal diameter of top neck, and the buckle at one-level filtering layer edge is fastened on
In the neck of top.
Preferably, bag body bottom, one-level filtering layer, two level filtering layer are in the structure to lower recess.
Preferably, the outside of bag body is provided with oscillation ring.
The beneficial effects of the utility model are：The utility model is by setting multistage filtering layer, by impurity classified filtering, mistake
Filter effect greatly promotes, meanwhile, the setting of neck, buckle, annular bucket neck causes one-level filtering layer, two level filtering layer, the assembling of bag body more
Add flexibility, cleaning impurity is more convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the part A detail drawing in Fig. 1 of the present utility model.
In figure：1- annular bucket necks；2- one-level filtering layers；3- oscillation rings；4- two level filtering layers；5- bag bodies；6- necks；7- buckles.
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As depicted in figs. 1 and 2, a kind of multistage filtering filter bag available for duplex strainer, including bag body 5, its feature exist
In, it is detachable successively from top to bottom in bag body 5 to be fixed with one-level filtering layer 2, two level filtering layer 4, one-level filtering layer 2, two level filtering layer 4,
The mesh of bag body 5 is sequentially reduced, and the annular bucket neck 1 that section is in reverse U shape shape is provided with the outside of the open top end of bag body 5.
Preferably, the inwall of bag body 5 be from top to bottom fixed with successively two sections be in positive U-shaped circular neck 6, one
Level filtering layer 2, the edge of two level filtering layer 4 are provided with the circular buckle 7 that section is in reverse U shape shape, the buckle 7 at the edge of two level filtering layer 4
It is fastened in bottom neck 6, the external diameter of the buckle 7 at the edge of two level filtering layer 4 is less than the internal diameter of top neck 6, the edge of one-level filtering layer 2
Buckle 7 be fastened in top neck 6.
Preferably, the bottom of bag body 5, one-level filtering layer 2, two level filtering layer 4 are advantageous to increase filtering surface in the structure to lower recess
Product, so as to improve filter effect.
Preferably, the outside of bag body 5 is provided with oscillation ring 3.
The utility model is placed in the stainless steel filtering net of duplex strainer, annular bucket neck 1 hangs over opening for stainless steel filtering net
Mouthful side is along upper, when needing to clear up impurity, it is only necessary to which one-level filtering layer 2, two level filtering layer 4 are taken out into cleaning from filter bag 5 i.e. successively
Can.By controlling oscillation ring 3 to vibrate, bag body 5, one-level filtering layer 2, the vibration of two level filtering layer 4 are come off and focus on bottom in time.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the various improvement that methodology and technical scheme of the present utility model are carried out are employed, or without
Improvement directly applies to other occasions, within the scope of protection of the utility model.
