Abstract
The utility model discloses a kind ofly along circumference waveform dust removal and filtration cloth bag, relate to dust-collecting bag technical field; It comprises steel skeleton and filter bag body, it is outside that described filter bag body is enclosed within steel skeleton, on filter bag body, there is filter bag head and filter bag bottom, described filter bag head is fixed on bag filter tubesheet in use, it also comprises the fixed band of a plurality of annulars, the cross section of described filter bag body is symmetrical waveform, and forms crest and trough, and described crest is made on above-mentioned annular fixed band; The beneficial effects of the utility model are: increased filter area, meeting under the intrinsic filter area requirement of deduster, can reduce the quantity of filtering cloth bag, deduster volume is dwindled greatly.
Description
[technical field]
The utility model relates to a kind of dust-collecting bag, and in particular, the utility model relates to a kind of along circumference waveform dust removal and filtration cloth bag.
[background technology]
The cross section of sack cleaner cloth bag is mostly rectangle and circle shape (also claiming pulse packet) at present, the filter area convergence filter bag surface area of its wall scroll filter bag, and rectangle is: (long+wide) * 2 * filter bag length; Circle is: diameter * π * filter bag length.In other words the certain space inner filtration area taking at it is constant, or is that it takes up room and cannot dwindle by the restriction of structure of filter bag again; Cannot increase again at shared space inner filtration area.Therefore use the sack cleaner volume of above cross-sectional shape dust-removal cloth-bag just very large, take up an area and take up room also greatly, manufacture that required ferrous materials amount is many, equipment investment is high, manufacturing cost is high; If dwindle the total filter area of the volume of deduster, will reduce, the dust emission that is in operation does not just reach index request.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, provide that a kind of this filtration cloth bag has increased filter area along circumference waveform dust removal and filtration cloth bag, meeting under the intrinsic filter area of deduster requires, can reduce the quantity of filtering cloth bag, deduster volume is dwindled greatly.
The technical solution of the utility model is achieved in that a kind of along circumference waveform dust removal and filtration cloth bag, it comprises steel skeleton and filter bag body, it is outside that described filter bag body is enclosed within steel skeleton, on filter bag body, there is filter bag head and filter bag bottom, described filter bag head is fixed on bag filter tubesheet in use, its improvements are: it also comprises the fixed band of a plurality of annulars, the cross section of described filter bag body is symmetrical waveform, and form crest and trough, and described crest is made on above-mentioned annular fixed band.
In above-mentioned structure, eight crests and eight troughs that the cross section of described filter bag body form to intersect, and crest and the trough state that is evenly distributed.
In above-mentioned structure, all make on fixed band on the summit of described crest, and described a plurality of fixed band is fixed on the outside of filter bag body from top to bottom successively.
The beneficial effects of the utility model are: one, dust-removal cloth-bag of the present utility model have increased filter area, in the situation that filter bag original volume (taking up room) is constant, can make its filter area increase to 1.8 times of left and right, in the situation that meet the total filter area of the former design of deduster (dust catching ability), require, can be by reducing filter bag quantity, deduster volume is dwindled greatly, reduce it and take up space; Two, deduster occupation of land and space are little, and operation and maintenance be relative convenience all; Deduster volume is little, compact conformation, the ferrous materials that making deduster consumes has reduced, and accessory use amount has also reduced, and greatly reduces the manufacturing cost of deduster; Three,, due to the waveform of filter bag cross section, when using compressed air reverse gas cleaning, reduce the suffered surface tension of filter bag, extended life of bag filter; Also, because waveform has been dwindled the spatial volume in filter bag, equal to have increased compressed-air actuated pressure during deashing, ash-removal effect is more obvious; Four, due to the waveform of filter bag cross section, increased the space between the filter bag being arranged in deduster, reduced the resistance of air intake, avoided sticking with paste the phenomenon of bag.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the generalized section at A-A place in Fig. 1.
[specific embodiment]
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing the specific embodiment of the present utility model is described.
Below preferred embodiment is described, but the technical solution of the utility model is not limited in the concrete form in this embodiment, those skilled in the art should easier associate the technical solution of the utility model and also can convert a little and be applied in other forms.
Shown in Fig. 1, Fig. 2, it is a kind of along circumference waveform dust removal and filtration cloth bag that the utility model discloses, this dust removal and filtration cloth bag comprises steel skeleton 10 and filter bag body 20, filter bag body 20 is enclosed within steel skeleton 10 outsides, on filter bag body 20, there is filter bag head 201 and filter bag bottom 202, filter bag head 201 is fixed on bag filter tubesheet in use, and steel skeleton 10 inserts in filter bag body 20, and its head flanging rides on bag filter tubesheet and covers filter bag head.
Further, dust removal and filtration cloth bag of the present utility model also comprises the fixed band 30 of a plurality of annulars, shown in Fig. 2, the cross section of described filter bag body 20 is symmetrical waveform, and form crest 203 and trough 204, and crest 203 is made on above-mentioned annular fixed band 30, in addition, in the present embodiment, the cross section of filter bag body 10 forms eight crests 203 and eight troughs 204 that intersect, and crest 203 and trough 204 state that is evenly distributed, all make on fixed band 30 on the summit of crest 203, and described a plurality of fixed band 30 is fixed on the outside of filter bag body 10 from top to bottom successively.
The utility model is by above-mentioned structure, increased filter area, in the situation that filter bag original volume is constant, can make its filter area increase to 1.8 times of left and right, in the situation that meet the total filter area of the former design of deduster, require, can deduster volume be dwindled greatly by reducing filter bag quantity, reduce it and take up space; In addition, the utility model deduster is taken up an area and space little, operation and maintenance be relative convenience all; Greatly reduce the manufacturing cost of deduster.Due to the waveform of filter bag cross section, when using compressed air reverse gas cleaning, steel skeleton is played a supporting role, and has reduced the suffered surface tension of filter bag, has extended life of bag filter; Also, because waveform has been dwindled the spatial volume in filter bag, equal to have increased compressed-air actuated pressure during deashing, ash-removal effect is more obvious; The waveform of filter bag cross section, has increased the space between the filter bag being arranged in deduster, has reduced the resistance of air intake, has avoided sticking with paste the phenomenon of bag.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, can there is various distortion and modification, the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
