It's full of vitality again. Let me explain the production requirements for the dust collector frame and filter bag.
A: Dust removal framework We generally use galvanized materials for production, which comply with the requirements of JB/T5917-91 "Technical Conditions for Filter Bag Frameworks for Bag Dust Collectors"
The dust collector bag cage has good usage characteristics and advantages during operation, and the galvanized skeleton has good dust removal effect. This dust collector bag cage can automatically discharge
It can also be manually discharged, but it should be discharged in the designated order. The surface of the frame has been treated with low-carbon steel wire and galvanized steel wire
Stainless steel wire and other materials are used as raw materials and welded in one go using a multi head high-frequency automatic spot welding machine to form a smooth surface without burrs. Because its quality will be direct
The frame manufacturing equipment introduced by my company (Hebei Feixiang Environmental Protection Equipment Co., Ltd.) affects the working condition and service life of the filter bag
Each frame of
can meet the requirements of lightness, smoothness, and straightness,
B： Dust filter bag; The production requirements are also very strict, and as the heart of the dust collector, it has a significant impact on its performance, seriously affecting the efficiency of exhaust gas treatment
. So using (), () treatment, PTFE film (coating) treatment materials, filter bag specifications and deviations
The technical requirements for sewing filter bags should comply with GB12625-90 "Technical Conditions for Filter Materials and Filter Bags of Bag Dust Collectors", and be able to meet the inlet concentration of 30g/m3.
In the case of capturing coal dust particles with a small particle size of 0.5 μ m, the dust removal efficiency is not less than 99.6% The outer filter bag can also be determined by its outer diameter or circumference
For cloth bags with snap rings that need to be fixed on the flower board or short tube, the tightening force of the bag under working conditions should not cause it to fall off from the flower board or short tube.
.The surface should not have any open lines, cracks, or scratches. The bottom of the mouth should be determined according to the needs, and the stitching spacing of the filter material should be moderate.
