OPEN FAST-CLEANING FILTER Russian patent published in 2009 - IPC B01D24/00 B01D24/46 

FIELD: purification equipment.

SUBSTANCE: invention relates to purification of natural and waste waters and can be used for removal of suspended substances from water. The proposed filter comprises a casing with filtration element and side pocket communicated via an opening, chutes, vibrators and system of inlet and outlet pipes with gates. The proposed invention differs from known designs in that the vertical pipe communicates, via the gate from below, with the initial water pipe and, from above, with tubular manifold. The tubular water distributors are attached to the lower part of the said manifold, the distributors being furnished with bottom holes arranged above perforated pan accommodating the filtration element. Note that aforesaid filtration element is fitted on guides to move thereon, the said guides being attached to the casing walls by rods. Note also that the filtration element located at the casing bottom accommodates the vibrators arranged vertically, all along the element height and length.

EFFECT: water purification efficiency increased by 10 to 15%, reduced interval between rinsing filter to one time a day; rinsing time is also reduced due to arrangement of vibrators inside casing and partial initial water oxygen saturation is allowed for.
