As the rib of the bag filter, the frame of the dust collector is easy to install and maintain, so people often ignore it when using and testing the bag filter. But the quality of the dust collector frame directly affects the service life of the bag filter. Therefore, when inspecting the dust collector skeleton, there are several points to pay attention to:
Whether the frame of the dust collector is fully galvanized in one molding, the surface is smooth and straight, does not produce burrs so that the filter bag is not damaged, the welding is uniform, the structure is reasonable, and the structure is firm. The trapezoid skeleton adopts a flat structure. The longitudinal ribs and anti-support rings of the trapezoid skeleton are evenly distributed, and have sufficient strength to prevent damage and deformation. In order to ensure the strength of the steel wire and improve the appearance quality, we use φ6.5 element steel drawing (Drawn to φ3mm), and then when the body is assembled on the butt welding fixture, the grinding meets the technical requirements. The trapezoid frame adopts organic silicon spraying or galvanizing, spray painting and other technologies. The coating is firm and corrosion-resistant. It avoids the rust of the cage bone surface and the adhesion of the filter bag after the dust collector works for a period of time, ensuring the smooth bag change and reducing the bag change process Damage to the dust bag in the middle.
