main technical requirements for the production of industrial dust collector
equipment are: the castings used in the dust collector must not have cracks, shrinkage holes, slag holes, insufficient pouring, and other defects that reduce the strength or have the appearance of the root dust collector. The welding seam of the structure of the dust collector shall be straight, without burn-through, cracks, pores, slag inclusion, and non-fusion defects. After welding, the residues such as welding and spatter should be removed. The fillet height of fillet welds shall not be less than the thickness of the thinner base metal. The inner and outer surfaces of the dust collector housing should be smooth and uniform, with a uniform arc, and the allowable deviation of its outer diameter or external dimensions is 5%. The splicing of the dust collector housing should be flat, and the longitudinal seams should be staggered. The connection and the place where the inspection door is installed should be tight.
After industrial pulverization, grinding and other processes, the generated dust has the characteristics of adhesion, explosiveness, and electrification in addition to maintaining the main physical and chemical characteristics of the original substance, and its spread may cause environmental pollution and harm the human body. In addition to health, it will also have a negative impact on production safety and product quality. Industrial dust collector is based on the specific characteristics of dust, mainly rely on gravity natural sedimentation, centrifugal separation, filtration, suction and other measures to separate dust particles to achieve a satisfactory dust removal effect. Dust collectors commonly used in ventilation projects include gravity sedimentation chambers, cyclone dust collectors, wet dust collectors, filter umbrella umbrellas, electrostatic dust collectors, etc.
