FILTERING BAG FOR BAG-TYPE FILTER Russian patent published in 2002 - IPC

FIELD: cleaning gases from solid particles; dust control in ferrous and non-ferrous metallurgy; manufacture of building materials, chemical, food- processing and other industries. SUBSTANCE: filtering bag includes sectional skeleton whose sections include end rings with central part located between them and secured to them. One of end rings is provided with at least two diametrically opposite stampings bent outside along axis of section; these stampings have holes. Spring-loaded clamp has pointed bent ends received by holes in stamping. Sizes of end rings which are plate-shaped in form are dictated by the requirement that diameter of circle formed by outer surfaces of bent-aside stampings is lesser or equal to diameter of hole of end ring of adjacent section of skeleton and center of hole in bent-aside stamping is located at distance from plane of end ring equal to sum of thickness of materials of adjacent end ring and half diameter of wire of spring-loaded clamp. One of end rings of filtering bag for-type filter may be provided with four stamping bent aside in opposite directions in pairs to facilitate coupling of sections without turning them through large angles. EFFECT: enhanced operational reliability; facilitated mounting and ease in maintenance. 4 cl, 1 dwg
