Dust filter bag, spring bag cage

Dust filter bag, spring bag cageAlso known as a spring frame, also known as a spring bag cage, it is welded in one go using specialized equipment. The skeleton is the rib of the filter bag, and the quality of the skeleton directly affects the working condition and service life of the filter bag. Our company's skeleton post-processing involves surface galvanizing or spraying, or surface coating or other coatings according to different customer requirements.

Dust filter bag spring bag cage is a supporting product of external filter bag dust collector. It is divided into two types: Venturi tube and non Venturi tube, and it has elasticity. The stretching length is generally 1.5M, 2M, 2.5M, and the diameter of the spring is generally less than 130 millimeters. It is made by winding steel wire with a diameter of 4 millimeters, and after stretching, it reaches 25 turns per meter. The surface is then treated with galvanizing. The spring skeleton design has a strong and reliable structure, and a longer service life.
Spring frame material: Low carbon steel wire, galvanized steel wire, stainless steel wire
Standard for Manufacturing Dust Removal Filter Bag Spring Bag Cage
The processing, transportation, and installation of the dust removal framework should comply with the standard JB/T 5917-91l of the Ministry of Machinery Industry
A. The production of cage type dust removal skeleton requires uniform distribution of support rings and longitudinal bars, as well as sufficient strength and rigidity. The wire used for the skeleton of Jincheng Company is domestic carbon steel Q235, with a diameter of 5-6mm. The wire steel is drawn to the required diameter by the equipment straightening machine to meet the requirements of strength and straightness. It can withstand the gas pressure of the filter bag during filtration and dust cleaning, and prevent damage and deformation caused by collisions and impacts during normal transportation and installation;
B. Adopting the industry's multi weld one-time high-frequency spot welding machine, 8-22 vertical bars can be welded at once, and all welding points of the skeleton are firmly welded without any detachment Virtual soldering and solder leakage; As shown in Figure 4
C. The surface of the skeleton in contact with the filter bag should be smooth and clean, and no welding scars are allowed Unevenness and burrs
D. The straightness of the skeleton axis is less than 24mm/meter. The Venturi tube is concentric with the cap, and the welding points are firm;
E、 The skeleton is made of galvanized wire and reinforced rings with a diameter of 4mm. For skeletons with a diameter of 145mm or less, 10 bars are evenly distributed, and reinforced rings with a diameter of 15-20mm are evenly distributed; 12 uniformly distributed reinforcement bars with a skeleton diameter of 145mm or more, and reinforced rings uniformly distributed with a diameter of 15-20mm;
F. The spring-loaded skeleton should have sufficient number of turns and elasticity, and the spacing should be uniform when pulled apart;
