ABSTRACT:
The self-cleaning filter for purifying a liquid from suspended particles has a housing with pipes for the inlet of the liquid to be purified and for the outlet of the clarified liquid, accomodating at least one filtering partition dividing the internal space of the housing into chambers for the liquid to be purified and for the clarified liquid, and means for flushing this partition with a countercurrent of the clarified liquid. The inlet pipe for the liquid to be purified is arranged on the housing within the chamber for the clarified liquid so that its geometric axis is substantially parallel with the plane of the filtering partition and communicates with another pipe received in the chamber for the clarified liquid so that its geometric axis extends centrally of this chamber, substantially perpendicular to the plane of the filtering partition, the latter having made therein an opening the edges whereof are connected to said another pipe.
The disclosed filter is characterized by reliable performance and relatively simple structure.
