A filter bag dust removal device for bag filter includes a dust removal box. The dust removal box is separated by a partition board into an upper exhaust chamber, a lower front filter chamber, an upper and lower exhaust passage and an inlet passage arranged on the lower rear side. A filter bag is arranged on the top of the filter chamber, an inlet hole is arranged on the partition board between the filter chamber and the inlet passage, and an exhaust outlet is arranged on the partition board between the exhaust chamber and the exhaust passage. The exhaust chamber is divided into several exhaust chambers arranged side by side by side by side by the partition board. The top surface of each exhaust chamber is inverted with the lifting cylinder. The lifting cylinder rod is inserted into the corresponding exhaust chamber. A cover plate opposite to the corresponding exhaust outlet is installed at the bottom end of each lifting cylinder rod, and an air inlet is arranged around the lifting cylinder on the top surface of each exhaust chamber. When the filter bag is used for cleaning dust, the power source of the bag filter need not be closed to ensure the normal operation of the filter operation. The structure is simple and the cost is low.

用于布袋除尘器的滤袋清灰装置
本技术涉及布袋除尘器,尤其涉及用于布袋除尘器的滤袋清灰装置。
技术介绍
布袋除尘器的滤袋在除尘过程中,随着附着在滤袋表面的灰尘增多,过滤气流的通道会逐渐缩小,导致滤袋对气流的阻力增加,长此以往会严重影响滤袋的除尘效果。因此,为了保证除尘效果,布袋除尘器在使用过程中都需要通过滤袋清灰装置及时清理附着在滤袋表面的灰尘。目前,滤袋清灰装置多采用脉冲清灰方式,脉冲式滤袋清灰装置主要包括脉冲阀、气包和喷吹管,喷吹管的一端穿过气包与脉冲阀连通,另一端伸入滤袋区。在清理滤袋时,打开脉冲阀,反向脉冲气流使滤袋内的压力急速上升,滤袋迅速向外膨胀,使附着在滤袋表面的灰尘抖落。由于脉冲气流与布袋除尘器的过滤气流方向相反,清理滤袋时需要将布袋除尘器的动力源关闭,影响正常过滤作业,且脉冲式滤袋清灰装置结构复杂,造价高。
技术实现思路
本技术是为了解决上述技术问题,提供一种用于布袋除尘器的滤袋清灰装置,在滤袋清灰时,无需关闭布袋除尘器动力源,保证过滤作业正常工作,结构简单,造价低。本技术的技术解决方案是:一种用于布袋除尘器的滤袋清灰装置,包括除尘箱,所述除尘箱由隔板分隔成上部的排气室、下部前侧的过滤室、下部后侧上下布置的排气道和进烟道,过滤室内顶部设置滤袋,过滤室与进烟道间的隔板上设有进烟孔,排气室与排气道间的隔板上设有排气口,其特殊之处在于:所述排气室由隔板分隔成多个左右并排布置的排气分室,每个排气分室外顶面倒置升降缸,升降缸缸杆插入对应排气分室,每个升降缸缸杆底端安装与对应排气口正对的盖板,且在每个排气分室内顶面位于升降缸四周设有进气口。进一步优选,在每 ...
