Chang Hao, dust removal efficiency is up to 99.999%.Dedusting filtering bag is to take terylene short fiber or long fibre to be raw material, and service life is usually
4-6 times of glass fabric, there is good gas permeability, and dust collection efficiency is high, holds deashing, efficiency of dust collection is up to 98.99%.
Filter bag is the heart in sack cleaner running, and the pulsed filter bag of usual cylinder type, which is vertically hung at, to be removed
Dusty gas enters deduster by air inlet in dirt device, the deflector through ash flue bucket, make part big dust particle in gas by
The effect of inertia force is separated, and falls directly into ash bucket.Dusty gas enters the sock filtration area of casing, most dust
The outer surface of filter bag is trapped in, and clean gas is entered inside filter bag by filtrate, purified gas enters by filter pocket mouths
Enter after upper box, then discharged by air outlet.Cage inside filter bag is used for supporting filter bag, prevents filter bag from collapsing, while it is helped
In the removing and redistribution of dirt cake.
Filter bag generally comprises filter bag body, support cage and the connector at filter bag head, and filter bag passes through connector
It is connected with filter bag installing plate (also referred to as card or porous plate) described at extraneous gas approach, bag head is installed on the mounting hole of card
In.The bag head of filter bag and the junction of card are also easy to produce gap, so that cause dust to be revealed from the junction, influence filtering effect
Really.
In view of the above-mentioned problems, existing patent No. CN201120065497.7, authorized announcement date is September in 2011 7, practical
New Name is：A kind of high temperature dedusting filter bag.This application case is including filter bag body, located at the intrinsic support cage of filter bag and sets
Connector above filter bag, filter bag body is elliptic cylindrical body, and filter bag body upper port is provided with annular flange, connector
Provided with elastic piston ring and packing ring with groove, packing ring is placed on elastic piston ring, and elastic piston ring and packing ring are located at the ring of filter bag body
In shape flange.The connection of this application case filter bag and card is more close reliable, and dust is difficult to reveal from the junction, but this application
Connecting-piece structure in case is complex, installs more inconvenient.
The content of the invention
1. the utility model technical problem to be solved
The purpose of this utility model is that the structure for overcoming existing dedusting filtering bag to exist is complex, installs more inconvenient
Not enough there is provided a kind of dedusting filtering bag easy for installation.Using the technical solution of the utility model, set in the annular flange of filter bag
Flexible collar, collar is the loop configuration do not closed, provided with one and card card between the upper Access Division of collar and lower Access Division
The neck of cooperation is connect, lower Access Division is provided with the inclined-plane for the inverted cone shape being engaged with the hole wall of the filter bag mounting hole of card, during installation,
Pressure is applied to elastic collar, collar shrinks under the oblique cooperation of lower Access Division and the filter bag mounting hole of card, when collar
When neck is depressed into concordant with card, collar elastic recovery, its neck is caught in the filter bag mounting hole of card, installs very convenient.
2. technical scheme
To reach above-mentioned purpose, the technical scheme that the utility model is provided is：
A kind of dedusting filtering bag easy for installation of the present utility model, including filter bag body and elastic collar, described filter bag
The top of body is provided with annular flange, and described collar is located in annular flange, and described collar is the loop configuration do not closed,
Described collar includes upper Access Division and lower Access Division, provided with one and card clamping between described upper Access Division and lower Access Division
The neck of cooperation, described lower Access Division is provided with the inclined-plane for the inverted cone shape being engaged with the hole wall of the filter bag mounting hole of card.
Further, described inclined-plane and horizontal plane angle are 60 °~80 °.
Further, described collar is made of spring steel.
3. beneficial effect
The technical scheme provided using the utility model, compared with existing known technology, is had the advantages that：
(1) a kind of dedusting filtering bag easy for installation of the present utility model, during installation, pressure, collar are applied to elastic collar
Under the oblique cooperation of lower Access Division and the filter bag mounting hole of card shrink, when the neck of collar is depressed into it is concordant with card when, card
Elastic recovery is enclosed, its neck is caught in the filter bag mounting hole of card, installs very convenient.
(2) a kind of dedusting filtering bag easy for installation of the present utility model, its collar body is flexible, passes through collar
Realize the engaging with card, structure very simple.
