Description
Technical field
The utility model is related to a kind of bag filters, and in particular to a kind of for collecting dust from the gas containing dust
Bag filter, belong to environmental protection machinery equipment technical field.
Background technology
Sack cleaner is a kind of dry type dust filtration device.It is suitable for trapping tiny, dry, non-fiber dust.Filter bag
Using weaving filter cloth or nonwoven felt at, dusty gas is filtered using the filtration of fabric, when containing
After dust and gas body enters sack cleaner, particle is big, heavy dust falls into ash bucket, contain since the effect of gravity settles down
There is the gas of relatively fine dust when passing through filtrate, dust makes gas be purified by detention.Filtrate after a period of use,
Due to effects such as sieving, collision, delay, diffusion, electrostatic, one layer of dust has been gathered on filter bag surface, this layer of dust is known as bonding layer,
In this later motion process, bonding layer is at the main filtration layer of filtrate, and by the effect of bonding layer, the larger filtrate of mesh also can
Obtain higher filter efficiency.As dust is in the accumulation of filter material surface, the efficiency and resistance of deduster all accordingly increase, when
When the pressure difference of filtrate both sides is very big, the tiny grit on filtrate some can be attached to and squeeze the past, make dust collector efficiency
Decline.In addition, the excessively high air quantity that can make dust pelletizing system of the resistance of deduster is remarkably decreased.
Novel inward flow filtration-type cloth bag is disclosed in the Chinese utility model patent document of Publication No. CN206214938U to remove

Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.As Figure 1-Figure 4, one
Kind bag filter, including shell 21, the shell 21 are internally provided with base portion 25, and the base portion 25 will be inside the shell 21
It is separated into the dust room 26 positioned at lower part and superposed air chamber 27；26 side of dust room is equipped with dusty gas entrance
36, bottom angled is vertically provided with ash bucket 28；The air chamber 27 is going out with 36 homonymy of dusty gas entrance equipped with purification gas
Mouth 37；27 outside of the air chamber is provided with vibration machine 22, and the swinging axle 23 of the vibration machine 22 passes through air chamber
27,23 periphery of the swinging axle is provided with multiple hook portions 24；Each hook portion 24 is all connected with that there are one dust settling pocket 1, the dust settling pockets 1
Elastic portion 19 is equipped in the middle part of periphery, dust settling pocket 1 is separated into upper bag 11 and lower bag 12 by the elastic portion 19；11 top of upper bag is equipped with
The loop connecting portion 14 being connect with the hook portion 24, lower 12 bottom of bag are provided with dust collecting part 16；The dust collecting part 16 includes ring-type
Elastomer 17 and the set picking bag 18 for wrapping up the endless elastomeric 17.
Preferably, the dust settling pocket 1 is wrapped up by tubular filter cloth, is internally provided with filter cake.
As shown in Figure 1, it is preferred that the dust settling pocket 1 is sutured by the first sewing line 13 in the longitudinal direction.
Preferably, the annular interconnecting piece 14 is sutured by the second sewing line 15 with dust settling pocket 1.
As shown in Figure 3, it is preferred that the elastic portion 19 is fixed on upper bag 11 and lower 12 periphery of bag by third sewing line 20

The operation principle of the utility model is as follows：
Dusty gas enters from dusty gas entrance 36, when entering ash bucket 28 through deflector 29, due to touching for deflector 29
The effects that hitting the reduction with gas velocity, coarse dust will be fallen into ash bucket 28, remaining fine particle dusts enters sky with gas
It is dusted in gas chamber 27.Dusty gas is purified by the cake filtration of dust settling pocket 1, due to the inertia of filter media fibre and fabric,
The effects that diffusion, barrier, hook, electrostatic, dust is delayed in the filter cloth of dust settling pocket 1, and purified gas escapes dust settling pocket 1
Outside, purified gas vent 37 is discharged.With the extension of filtration time, filter cake accumulation dust impurity to it is a certain amount of when, pass through
Operate vibration machine 22 swinging axle 23 so that dust settling pocket 1 filter cloth vibration, the filter cake quilt of the excessive dust impurity of accumulation can be made
Ash bucket 28 is collected and is discharged to the outside of dust arrester 21.When upper bag 11 vibrates, 19 dilation of closed elastic portion can be effective
Ground prevents that fold occurs in lower bag 12.Since dust settling pocket 1 is hardly expanded and is shunk so that the burden of dust settling pocket 1 is small.Therefore,
When the operation of filter cake is repeatedly repeated for a long time, can its reduce the permanent elongation that is generated in dust settling pocket 1, this can be with
The change in size for preventing dust settling pocket 1 reduces the possibility of perforation, to improve the durability of filter cloth, and then improves efficiency of dust collection.
