Abstract

一种用于袋式除尘器的外槽式密封滤袋。它是袋口采用双层滤布,在双层滤布外侧缝制2条厚毡条,并在双层滤布中间设有弹性钢片,安装时将2条厚毡条之间的缝隙卡在花板孔上,牢固而严密地使滤袋固定在花板上。

Description

外槽式密封滤袋
所属技术领域
本实用新型涉及一种用于袋式除尘器的外槽式密封滤袋。
背景技术
袋式除尘器为现在工业中应用最为广泛的高效除尘器之一,滤袋是袋式除尘器中的核心部件。目前,公知的滤袋采用内槽式结构使其与花板固定,但是这种固定方式安装时容易出现差错,在袋式除尘器在运行时易发生掉袋或密封不严的问题,导致除尘效率下降和袋式除尘器不能正常运行,
发明内容
为了克服现有的袋式除尘器易发生掉袋或密封不严的不足,本实用新型的目的是提供一种外槽式密封滤袋,从而使滤袋安装时,操作方便,而且滤袋与花板的固定可靠严密,不会发生掉袋现象,并提高滤袋的密封性能。
本实用新型的解决其技术问题所采用的技术方案是:滤袋的袋口用双层滤布缝制,在双层滤布的外侧缝制2条厚毡条,毡条的材料与滤袋的材料相同,厚度L1为4mm~11mm,宽度L2为8mm~16mm。2条毡条之间的缝隙与花板厚度相同。在双层滤布的中间设有一条弹性钢片,钢片的宽度不小于2条厚毡条的宽度加上花板厚度之和。安装时将滤袋口上2条厚毡条之间的缝隙卡在花板孔上,从而达到非常牢固而且严密地使滤袋固定在花板上。
本实用新型的有益效果是,可以使滤袋和花板严密地固定在一起,不会发生掉袋现象,并提高了密封性。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型的示意图。
图2是图1的I向部视图。
图中1.滤袋袋口内侧滤布,2.滤袋袋口外侧滤布,3.厚毡条,4.弹性钢片,5.花板。
具体实施方式
首先将厚毡条(3)按尺寸要求缝制于滤袋袋口外侧滤布(2)上,再将弹性钢片夹入内侧滤布(1)与外侧滤布(2)中间后,将2层滤布缝制在一起。使用时,如图3所示方式将滤袋放入花板(5)孔内,即可完成安装。

Claims (3)
