FILTER FOR SEPARATION OF SUSPENSION

摘要

A filter for separation of a suspension is used in chemical, food and agricultural industries. In the filter, a continuous flow of a suspension is directed downwards into a gap (13) between filtering elements (4) with their simultaneous cleaning with a gas flow which is fed through openings (15) of tubes (14) in the form of bubbles on the surface of each of the filtering elements (4) on the side of the suspension flow and in the direction which is opposite to the direction of that flow. The filtering elements (4) consist of hollow reservoirs (8) connected to a filtrate removing sleeve (5). The tubes (14) are located in the lower part of the filtering elements (4) along and very close to their lateral sides so that the bubbles coming out of the openings move along the surface of the filtering elements (4) and clean the latter.
