The invention provides a dust removal filter cartridge, which belongs to the field of operation technology. The utility model solves the problem that the dust at the bottom of the existing filter barrel folds is difficult to be cleared and gradually accumulated. The filter cartridge comprises a bottom plate and a filter material, the filter material folds into folds and forms a plurality of grooves; the outer edge of the bottom plate has a plurality of teeth with circumferential uniform distribution, and the adjacent teeth have a groove between them; the lower end of the groove with an opening outward in the filter material is opposite to the groove; the lower end of the groove with an opening inward in the filter material coincides with the teeth; and the bottom of the filter material is overlapped with The part and the teeth are fixed by glue. The dust collector is provided with a tooth groove connected with an opening facing an inner groove at the outer edge of the bottom plate, so that the bottom of the opening facing an inner groove has no parts to drag the accumulated dust, and the dust accumulated at the bottom of the opening facing an inner groove is easy to fall off during the back blowing process. The dust remover cartridge has the advantages of not easy to accumulate dust, significantly prolonging the cleaning and maintenance cycle, timely removing adhesion dust, and effectively improving the installation of the dust remover.

除尘滤筒
本专利技术属于作业
,涉及一种分离装置,特别是一种除尘滤筒。
技术介绍
滤筒是由一定长度挺括的滤料折叠成褶,首尾粘合而成的星形过滤筒。如图1是现有常见一款除尘滤筒,除尘滤筒包括滤材、内网和底板,底板的外缘具有环形定位槽,滤料的底部嵌设在环形定位槽内。申请人曾提出了一种除尘器(授权公告号CN205127603U),其中应用的滤筒为图1所示结构。除尘器在使用过程中需要对滤筒进行反吹,用于清除外侧的粉尘。在实际使用过程中滤筒褶皱底部的粉尘难以被清除,而且粉尘会逐渐堆积,即从褶皱的底部逐渐向上堆积,不但影响滤筒除尘效率,若粉尘中含有易燃易爆粉尘,还使安全风险显著增加;以及滤筒经过需要卸下进行清理,由此又影响正常的生产效率。
技术实现思路
本专利技术提出了一种除尘滤筒,本专利技术要解决的技术问题是如何使除尘滤筒不易堆积粉尘。本专利技术的要解决的技术问题可通过下列技术方案来实现:一种除尘滤筒,包括底板和滤材,滤材折叠成褶以及形成多条细沟槽;底板的外缘部具有多个周向均匀分布的齿,相邻齿之间具有齿槽;滤材中开口朝外的细沟槽下端与齿槽正对,滤材中开口朝内的细沟槽下端与齿重合,滤材的底部与齿之间通过胶粘结固定。与现有技术相比,本除尘滤筒在底板外缘部开设有与开口朝内细沟槽相连通的齿槽;由此使得开口朝内细沟槽的底部无部件拖住堆积的粉尘;除尘器在反吹过程中,堆积在开口朝内细沟槽底部的粉尘也极易掉落。即使粉尘存在逐渐堆积的可能性,但由于堆积重量逐渐增大以及在反吹气压的捶打下,粉尘也具有自动掉落的可能性;由此显著地降低了粉尘大量堆积在开口朝内细沟槽内可能性,基本杜绝粉尘完全 ...
