VIBROPULSATING FILTER Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: filter has vertical sinusoidal members arranged on equidistant sinusoidal surfaces. These members are assembled from corrugated perforated rockers whose arms are symmetrical relative to normal to extreme points of sinusoid. All-woven or sewn hoses are easily drawn on such members. Filtering elements are connected to filtrate discharge manifold by means of threaded joint. Elements of body increase filtering surface to 40 % as compared with known similar filters and provide for effective and through regeneration of filtering cloth when pulsating source is available in filter and ease of drawing the fabric hose of metal framework. Filter provides for reduction of metal usage per unit of filtering surface, reduction of power requirement and working areas, ease of its manufacture and servicing, which makes it one of important items of equipment of advanced technology. EFFECT: increased filtering surface per unit of filter volume, effective discharge of sediment from filtering surface and reliable regeneration. 5 cl, 4 dwg
