Abstract
The utility model discloses an unequal-cross-section dust filter bag. The unequal-cross-section dust filter bag comprises a cloth bag cage or an anti-flat ring, wherein the cross section size of a cloth bag is changeable from one end to the other end along an axial direction, and the biggest cross-section end of the cloth bag is arranged on a filter head plate; and the cloth bag cage or the anti-flat ring which is matched with the cross section size variation of the cloth bag is arranged in the cloth bag. By adopting the structure form of the unequal cross section dust filter bag disclosed by the utility model, the flow rate of inside and outside gases of the filter bag can be more reasonable by fully utilizing the inner space of the dust collector, the performance of the dust collector is increased, and the manufacturing cost of the dust collector is lowered.
Description
Technical field
The utility model relates to a kind of sack cleaner and uses the dedusting filter bag, and specifically a kind of non-constant section amasss the dedusting filter bag.
Background technology
Along with carrying out and implementing of national energy-saving and emission-reduction policy, the application broadened of sack cleaner, the ash-clearing technology of deduster and performance parameter etc. have all obtained progressively improving and improving.And the version of dust-removal cloth-bag all is that uiform section is long-pending at present.The cross sectional shape of cloth bag is circular, oval, square a, rhombus etc., and the length maximum can be accomplished tens meters, but all is that uiform section is long-pending along its length.Shrinking-proof ring that corresponding cloth bag is inner or bag cage (claiming the cage bone again) also all are uiform section long-pending (or uiform sections).
Fig. 1 is long-pending (or uiform section) cloth bag sketch map of outside filtering type uiform section, and one group of cloth bag 11 is arranged on the card 13, is provided with bag cage 12 in cloth bag 11 inside.It is characterized in that cloth bag about in the of 11 uiform section long-pending, cloth bag inner pouch cage 12 also is uiform section long-pending (or uiform section) bag cage.Fig. 2 is the cloth bag sketch map of inward flow filtration-type deduster, and one group of cloth bag 21 is arranged on the card 23.The deduster filter type is an inward flow filtration-type, and then the shrinking-proof ring 22 of cloth bag 21 set inside also is uiform section long-pending (or uiform section).The cloth bag of existing this form can not make full use of the inner space of deduster at present, and the performance of deduster is low.
Summary of the invention
In order to overcome the problem that prior art exists; The purpose of the utility model provides the long-pending dedusting filter bag of a kind of non-constant section; This dedusting filter bag adopts the version of the long-pending cloth bag of non-constant section; Can make full use of the inner space of deduster, make the inside and outside gas flow rate of filter bag more reasonable, improve the performance of deduster and reduced the cost of deduster.
The purpose of the utility model realizes through following technical scheme:
A kind of non-constant section amasss the dedusting filter bag, comprises cloth bag, it is characterized in that: the sectional area size of said cloth bag is changed by an end to the other end vertically, and the maximum end of the sectional area of cloth bag is arranged on the card; In cloth bag, be provided with bag cage or the shrinking-proof ring suitable with the sectional area change in size of cloth bag.
In the utility model, if outside filtering type, the sectional area size of said cloth bag is axially diminished by upper end to lower end edge, and the upper end of cloth bag is arranged on the card; In cloth bag, be provided with the bag cage suitable with the sectional area change in size of cloth bag.The sectional area size of bag cage also is from top to bottom to diminish.
If inward flow filtration-type, the sectional area size of said cloth bag axially becomes big by upper end to lower end edge, and the lower end of cloth bag is arranged on the card; In cloth bag, be provided with and the suitable shrinking-proof ring of the sectional area change in size of cloth bag.The sectional area size of shrinking-proof ring also is to become big from top to bottom.
The utility model adopts long-pending (or variable cross-section) cloth bag of non-constant section, promptly is that cloth bag length direction sectional area changes, and its architectural feature is: up big and down small or up-small and down-big.Filter bag is made the long-pending formula of non-constant section, have following advantage: the inside and outside gas flow rate of filter bag is more reasonable; The card utilization rate increases, and promptly the cloth bag area that can install of card unit are increases.The socket transportation each other of cloth bag bag cage significantly reduces the freight.
Description of drawings
Fig. 1 is the long-pending cloth bag sketch map of outside filtering type uiform section in the prior art.
Fig. 2 is the long-pending cloth bag sketch map of inward flow filtration-type uiform section in the prior art.
Fig. 3 is the long-pending cloth bag sketch map of outside filtering type non-constant section in the utility model.
Fig. 4 is the long-pending cloth bag sketch map of inward flow filtration-type non-constant section in the utility model.
The specific embodiment
The described outside filtering type non-constant section of a kind of the utility model amasss the dedusting filter bag, sees Fig. 3, comprises cloth bag 1, and the sectional area size of cloth bag 1 is axially diminished by upper end to lower end edge gradually, and the maximum end of the sectional area of cloth bag 1 is arranged on the card 3; In cloth bag 1, be provided with the bag cage 2 suitable with the sectional area change in size of cloth bag.The sectional area size of bag cage 2 also is from top to bottom to diminish.
Present embodiment adopts long-pending (or variable cross-section) cloth bag of non-constant section, promptly is that cloth bag length direction sectional area changes: up big and down small, the inside and outside gas flow rate of filter bag is more reasonable; The card utilization rate increases, and the socket transportation each other of cloth bag bag cage significantly reduces the freight.
Embodiment 2
The described inward flow filtration-type non-constant section of a kind of the utility model amasss the dedusting filter bag, sees Fig. 4, comprises cloth bag 1, and the sectional area size of cloth bag 1 axially becomes big gradually by upper end to lower end edge, and the lower end of cloth bag 1 is arranged on the card 3; In cloth bag 1, be provided with the shrinking-proof ring 4 suitable with the sectional area change in size of cloth bag.The sectional area size of shrinking-proof ring 4 also is to become big from top to bottom.
