[0002] The dust collector frame, also known as the dust bag cage, is an indispensable accessory of the bag dust collector. It is used as a frame to support the dust filter bags. It can be compatible with six, eight, ten, twelve, sixteen, eighteen, twenty, and twenty-four ribs. The dust bag frame is installed on the flower plate holes in the pulse dust collector and the air box pulse dust collector to support the dust filter bags to prevent collapse. The quality of the bag dust collector frame directly affects the service life of the dust filter bags and the dust removal effect of the bag dust collector. It is one of the important accessories in the dust collector and is widely used in metallurgy, chemical industry, coking, power generation, non-ferrous smelting, steel, building materials, coal mining and other industries.

The lower wall of the fixed plate is provided with an air duct, and the air duct is connected to a base through a telescopic skeleton used to adapt to the length of the bag body. This utility model, by setting the outer diameter of multiple sets of telescopic joints to be smaller than the outer diameters of the base and the air duct, ensures that after the dust bag is fixed to the air duct and the outer wall of the base, the dust bag does not contact the outer wall of the telescopic joint, thus avoiding wear. The multiple sets of telescopic joints can be freely matched with the clamping columns and multiple slots, and the overall length of the telescopic skeleton can be easily adjusted to accommodate dust bags of different lengths. The length adjustment between the multiple sets of telescopic joints can be completed by rotating, pulling, and then rotating in the opposite direction, which requires few movements and is very convenient to adjust.

[0004] Although the device has adjusted the length of the frame, the strength of the frame may cause bending, breaking, and welding during use, affecting the dust removal effect of the dust bag. Utility Model Content
