The filter contains case (1) and removing cap (2) mechanically connected, made with exit central passage (3) to supply liquid into main line (4) for pump absorption, cylindrical filtering net (5) placed between case (1) and cap (2). Case (1) is made by the absorption side as a truncated perforated hollow cone (6) along whose big base periphery a non square full slot (7) for a net end (5) is made with a shot bow-shaped wall (8) with two parallel rectangular slots (9) in the internal side to place longitudinal net ends (5) with uprights (10), that possess butt mounting holes for threading elements (11). Cap (3) is made as a through connecting pipe with a cylindrical reach-through hole (3) and is placed around this connecting pipe flange (12), along the periphery of the latter a non square full slot (14) for another net end (5) is made with pass-through holes (15) to place threading elements (screws) (11) in upright holes (10) of vase (1). Slots (7, 9, 14) form the continuous contour to place net ends (5) along their entire perimeter. Case (1) and cap (2) are made of plastic and net (5) is made split (rectangular and laid out) of steel. Hollow cone (6) of case (1) is made divided by webbing (16) in four sectors perforated by round holes. Uprights (10) are made together with webbing (16). This version makes the filter durable, reliable and repairable. |
