FIELD: equipment for cleaning various suspensions, emulsions and pulse from mechanical impurities. SUBSTANCE: vibrating screen has frame, intake manifold and vibration housing mounted on frame by means of springs; vibration housing is provided with filtering strainer forming at least one V- shaped or U-shaped passage. Edges of filtering strainer are secured on tension rolls. Vibration housing on side of intake manifold is mounted on springs made in form of hinge with end sections: one end is secured on frame and other end is secured on vibration housing. Hinge is fitted on cantilever mounted on frame. On opposite side (relative to intake manifold) vibration housing is mounted on coil cylindrical springs. Point is securing the end section of spring made in form of hinge and axis of cylindrical spring are located at distance not exceeding 0.25 of length of vibration housing from edges of this housing. Filtering strainer is made in form of cloth with at least three reinforcing strips secured on either side of strainer opposite one another; these strips are made from elastic or plastic material; two strips are located over edges of strainer cloth. EFFECT: increased throughput; enhanced operational reliability. 3 cl, 4 dwg
