Abstract
The invention belongs to flue gases purification fields, more particularly to a kind of filter bag with automatic telescopic regulatory function, it includes bag head, bag body, expansion ring, adjustable spring and bag bottom, the bag head sewing is at the top of bag body, the expansion ring is fixed in the middle part of bag body, the adjustable spring is fixed on expansion ring, and the bag bottom sewing is in bag body bottom.Filter bag of the present invention has automatic telescopic regulatory function, and after filter bag is shunk after heated, the telescopic device being arranged with bag can compensate stroke automatically, can not be shunk after avoiding a bag body from being stuck in bag cage caused by the tearing of bag body or bag cage lifting.The filter bag and conventional structure of filter bag are essentially identical, and transport mounting means is identical as conventional filter bag, has the characteristics that structure is simple, adaptable.
Description
Technical field
The invention belongs to flue gases purification fields, and in particular to a kind of filter bag with automatic telescopic regulatory function.
Background technique
With the raising of national requirements for environmental protection, in industries such as electric power, metallurgy, building materials, flue dust in industrial pollutants is arranged
The requirement put has increased significantly, after especially country implements minimum discharge policy to coal-burning power plant, coal-burning power plant's flue dust
The requirement of discharge has increased significantly, and many areas have been carried out 5mg/m3Emission limit, sack cleaner as protect
One of the major technique of flue dust low concentration stable emissions is demonstrate,proved, the range of application is gradually increased, core of the filter bag as sack cleaner
One of center portion part, the integrality and installation accuracy of bag body directly determine the smoke catching effect of deduster.However during installation,
The factors such as bag cage deformation or installation inclination are likely to result in filter bag distortion, and the bag cage position that filter bag is distorted after the installation is completed can
It can be tightly attached in bag cage, when thermal condition operation, after filter bag bag body is shunk, the filter bag position that is distorted generates biggish rub
Power is wiped, which may tear filter bag or bag cage is caused to rise, and then may cause efficiency of dust collection decline, in addition, rotation spray
It blows in sack cleaner, after bag cage cage mouth is too many higher than card, rotating arm may be hindered to rotate, cause deashing device that can not transport
Turn, and then entire dust removing units is caused to fail.
Summary of the invention
To solve the above problems, there is flexible adjust the invention discloses a kind of filter bag with automatic telescopic regulatory function
Section structure, though filter bag part and bag cage clamping, the contraction of bag body can be also adapted under thermal condition, will not cause bag body tearing or
The problem of bag cage is lifted.
To realize the above-mentioned technical purpose, the following technical solution is employed by the present invention:
A kind of filter bag with automatic telescopic regulatory function, including filter bag ontology, expansion ring, adjustable spring, the filter bag ontology
It is from top to bottom respectively bag head, bag body and bag bottom, the quantity of the expansion ring is 10-30, and flexible central spacer is fixed on a bag body
Outside, the adjustable spring are fixed between two neighboring expansion ring.
As an improvement of the present invention, the spacing between the expansion ring is identical.
As an improvement of the present invention, multiple adjustable springs are set between two neighboring expansion ring.
As an improvement of the present invention, the expansion ring, adjustable spring are corrosion-resistant metal materials.
Compared with prior art, the beneficial effects of the present invention are:
For filter bag ontology after heated shrink, the telescopic device being arranged with bag can compensate stroke automatically, avoid a bag body
The tearing of bag body caused by can not being shunk after being stuck in bag cage or bag cage lifting.Filter bag of the present invention and conventional structure of filter bag
Essentially identical, transport mounting means is identical as conventional filter bag, has the characteristics that structure is simple, adaptable.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Reference signs list:
1, bag head；2, bag body；3, bag bottom；4, expansion ring；5, adjustable spring.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.
As shown in Figure 1, the invention discloses a kind of filter bag with automatic telescopic regulatory function there is automatic telescopic to adjust
Function, including bag head 1, bag body 2, bag bottom 3, expansion ring 4 and adjustable spring 5, the sewing of bag head 1 is in 2 top of bag body, Ruo Ganshen
Contracting ring 4 is fixed on outside bag body 2, and the bag body 2 in expansion ring 4 is folded state, and adjustable spring 5 is fixed on expansion ring 4, bag bottom
3 sewings are in 2 bottom of bag body.
In the present embodiment, after heated shrink, the adjustable spring 5 being arranged on bag body 2 automatically springs open filter bag ontology, stretches
The bag body 2 of 4 infolding overlapping state of contracting ring automatically opens, and compensation filter bag caused stroke when shrinking can effectively avoid a bag body
The tearing of bag body caused by can not being shunk after being stuck in bag cage or bag cage lifting.
The technical means disclosed in the embodiments of the present invention is not limited only to technological means disclosed in above embodiment, further includes
Technical solution consisting of any combination of the above technical features.
