FIELD: mechanics.
SUBSTANCE: invention refers to filters used for foreign particles filtering off from water supplied to pipeline system. First version of filter design: filter contains oblong collector enclosing closed channel provided with outlet, connected to suction device, also it contains lots of inlets arranged along channel length, filtering elements arranged in each inlet, and a lot of devices for flow control; each of them contains partition forming collecting canal connected to one or more inlets and ending with outlet lower in flow direction of one or more inlets. Second version of filter design: filter contains collector which encloses closed volume and contains outlet connected to suction device. Collector contains lots of oblong slotting inlets, plate-shaped filtering element off-setting from each slotting inlet. Filtering elements contain frame along the perimeter and a pair of meshed screens penetrable for liquid attached to frame opposite to each other and at a distance and at least one channel for liquid flow arranged between them and connected to mentioned closed volume by means of boundary lateral edge of frame and slotting inlet.
EFFECT: compactness, high efficiency.
