Problems solved by technology

[0002] The existing bag cage includes a plurality of vertical ribs arranged at intervals along the circumferential direction, and horizontal ribs connected between the plurality of vertical ribs. The ribs play the role of supporting the opening of the filter bag. The outer peripheral surface of the filter bag has ring-shaped grooves extending in the circumferential direction on the position close to the bag mouth and on the outer peripheral surface of the lower connecting pipe. The groove of the filter bag and the lower connecting pipe The position of the groove corresponds well, and then the filter bag is fastened on the lower connecting pipe through the hoop, the lower connecting pipe can separate the lower part of the upper connecting pipe, and the upper part of the upper connecting pipe has a circumferential flange, which is fastened On the edge of the hole of the flower plate, and then fix the circumferential flanging of the upper nozzle on the flower plate with screws, so that when installing the bag cage and filter bag on the flower plate, the installer must climb above the flower plate to carry out the installation. The installation of the takeover can only complete the installation of the bag cage, and the installation operation is troublesome

Embodiment Construction

[0018] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] exist Figure 1-6 Among them, a built-in bag cage, including a plurality of vertical ribs 1 arranged at intervals along the circumferential direction, and transverse ribs 2 connected between the lower parts of the plurality of vertical ribs 1, and the positions where the plurality of vertical ribs 1 are located above the transverse ribs 2 can be Elastically deformable, in this embodiment, the vertical ribs 1 are made of metal material, so they can be elastically deformed, the multiple vertical ribs 1 surround the frame of the bag cage, and the horizontal ribs 2 ensure the stability between the lower parts of the multiple vertical ribs 1 Positioning, the tops of the multiple vertical ribs 1 are all bent outwards to form a hook 3, and the upper ends of the multiple vertical ribs 1 are provided with a stretching structure 4 that can expand the ...

Abstract

The invention discloses a bag type dust-collecting built-in bag cage and a combined mounting structure of the bag cage and a filtering bag on a tube sheet. The bag cage in inserted into the filtering bag, and when the bag cage is mounted into a hole of the tube sheet a mounting worker forcedly folds the upper ends of vertical ribs and the upper end of the filtering bag, so that the upper ends of the bag cage and the filtering bag can pass through the tube sheet hole; the vertical ribs are released and hands are stretched into the adjacent hole of the tube sheet to operate an expanding structure, so that a plurality of the vertical ribs are stably expanded; lifting hooks at the top ends of the plurality of the vertical ribs stretch out of the opening of the filtering bag to be hooked on the upper surface at the periphery of the hole of the tube sheet; and meanwhile, the opening of the filtering bag is tightly held by elastic acting force of an elastic piston ring, so that the hole edge of the tube sheet hole is inserted into a groove of the opening of the filtering bag; and therefore, the filtering bag is stably positioned. When mouting the bag cage and the filtering bag, the mounting worker only needs to stand below the tube sheet to operate the expanding structure from the adjacent tube sheet hole to finish the mounting without need of climbing on the tube sheet, so that the mounting operation is convenient and the height of a space above the tube sheet is saved.

Description

technical field [0001] The invention relates to a built-in bag cage for bag type dust removal, and also relates to a combined installation structure of the bag cage and a filter bag on a flower plate. Background technique [0002] The existing bag cage includes a plurality of vertical ribs arranged at intervals along the circumferential direction, and horizontal ribs connected between the plurality of vertical ribs. The ribs play the role of supporting the opening of the filter bag. The outer peripheral surface of the filter bag has ring-shaped grooves extending in the circumferential direction on the position close to the bag mouth and on the outer peripheral surface of the lower connecting pipe. The groove of the filter bag and the lower connecting pipe The position of the groove corresponds well, and then the filter bag is fastened on the lower connecting pipe through the hoop, the lower connecting pipe can separate the lower part of the upper connecting pipe, and the upp...
