Description
Technical field
It the utility model is related to filter bag technical field, more particularly to a kind of filter bag with sealing function.
Background technology
Filter bag is the key component in sack cleaner running, and usual cylinder type filter bag is vertically hung at deduster
In.The fabric and design of filter bag, which should try one's best, to be pursued high efficiency filter, is easy to dust stripping and effect durable in use.In pulse and gas tank
In formula pulse dust collector, dust is attached to the outer surface of filter bag.When dusty gas passes through deduster, dust is trapped in filter bag
Outer surface, and clean gas by filtrate enter filter bag inside.Cage inside filter bag is used for supporting filter bag, prevents filter bag from collapsing
Fall into, while it contributes to the removing and redistribution of dirt cake.
For traditional filter bag because sealing structure is simple, sealing effectiveness is poor, after filter bag is installed into deduster, in junction
The problem of leaking out usually occurs, this will cause the dust removing effects of deduster to be greatly lowered, or even influence deduster just
Often use process.
Utility model content
The purpose of this utility model is to solve the shortcomings that filter bag sealing effectiveness difference present in prior art, and is proposed
A kind of filter bag with sealing function.
To achieve these goals, the utility model employs following technical scheme：
A kind of filter bag with sealing function, including filter bag cylinder are designed, the filter bag cylinder bottom is stitched with filter bag and dragged
Bottom, the filter bag cylinder include basic unit, the basic unit by refractory glass fibre, aramid fiber and Fypro it is compound and
Into, be coated with one layer of teflon coatings outside the basic unit, the filter bag cylinder top is connected with sealing ring, and the sealing ring with
Filter bag cylinder is coaxially disposed, and the internal diameter of the seal ring is equal with filter bag cylinder, and the sealing ring external diameter is more than filter bag cylinder, institute
State sealing ring upper end and be connected with skeleton adpting flange, the sealing ring is hollow structure, and forms annular accommodating cavity, described accommodating
Intracavitary is equipped with sponge strip, and the sponge strip external diameter matches with accommodating cavity internal diameter, and the sponge strip both ends are bonded by glue,
On the outside of the filter bag cylinder upper end, and what is be coaxial therewith is bonded with multigroup extrusion ring, and the extrusion ring is placed in below sealing ring.
Preferably, on the outside of the filter bag cylinder and along its circumference, a plurality of wrinkle resistant rib is uniformly bonded with equal intervals, and
The wrinkle resistant rib is specially vulcanie bar.
Preferably, it is double-decker that the filter bag, which drags bottom, is combined between two layers by sewing up, and the filter bag drags bottom
It is made up with filter bag cylinder of same material.
Preferably, the filter bag cylinder and sealing ring are integral type structure.
Preferably, the extrusion ring is specially soft rubber bar.
The utility model proposes a kind of filter bag with sealing function, beneficial effect is：By by original filter bag
Simple sealing structure is improved so that filter bag has the sealing function of high intensity, so as to solve existing filter bag sealing knot
Structure is simple, and sealing effectiveness is poor, and caused by deduster dust removing effects decline the problem of.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of filter bag with sealing function structural representation；
Fig. 2 be the utility model proposes a kind of filter bag with sealing function filter bag tube structure schematic diagram；
Fig. 3 be the utility model proposes a kind of filter bag with sealing function sealing ring internal structure schematic diagram.
In figure：Sealing ring 1, filter bag cylinder 2, wrinkle resistant rib 3, filter bag drag bottom 4, extrusion ring 5, skeleton adpting flange 6, basic unit
7th, teflon coatings 8, accommodating cavity 9, sponge strip 10.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-3, a kind of filter bag with sealing function, including filter bag cylinder 2, the bottom of filter bag cylinder 2 are stitched with filter
Bag drags bottom 4, and it be double-decker that filter bag, which drags bottom 4, is combined between two layers by sewing up, and filter bag drag bottom 4 and filter bag cylinder 2 by
Same material is made, and drags bottom 4 to be designed as double-decker filter bag, can effectively strengthen the load performance that filter bag drags bottom 4.
Filter bag cylinder 2 includes basic unit 7, basic unit 7 by refractory glass fibre, aramid fiber and Fypro it is compound and
Into basic unit 7 is coated with one layer of teflon coatings 8 outside, and refractory glass fibre, aramid fiber and Fypro are combined
Basic unit 7 cause filter bag cylinder 2 have high temperature resistant, corrosion-resistant and hydrolytic resistance excellent properties, teflon coatings 8 have it is resistance to
The characteristics of high temperature and lubrication, it greatly reduces the coefficient of friction on filter bag surface.
The top of filter bag cylinder 2 is connected with sealing ring 1, and filter bag cylinder 2 and sealing ring 1 be integral type structure, and sealing ring 1 and
Filter bag cylinder 2 is coaxially disposed, and the internal diameter of sealing ring 1 is equal with filter bag cylinder 2, and the external diameter of sealing ring 1 is more than filter bag cylinder 2, sealing
Enclose 1 upper end and be connected with skeleton adpting flange 6, sealing ring 1 is hollow structure, and forms annular accommodating cavity 9, is housed in accommodating cavity 9
There is sponge strip 10, and the external diameter of sponge strip 10 matches with the internal diameter of accommodating cavity 9, the both ends of sponge strip 10 are bonded by glue, when with sealing
When the sealing filter bag of circle 1 cylinder 2 is with skeleton 6 junction of adpting flange, because sealing ring 1 is by big extruding force so that sponge strip
10 are deformed, so as to play good sealing effectiveness.
