Description

The invention relates to devices for the purification of liquids from suspended substances, in particular for the purification of natural and waste waters from mechanical impurities, and can be used in various industries and public utilities.

The aim of the invention is to increase the efficiency of liquid purification due to the intensification of sedimentation of suspended substances.

The drawing shows an apparatus for cleaning liquids from suspended substances, a general view.

The apparatus consists of a vertical cylinder. The liquid to be cleaned is supplied through conduit 12 to the lower part of housing 1, to the first cleaning chamber 5 from below. At the entrance to the chamber, the flow of fluid meets in its path the baffling surface of the cone 7 of element 5 and 6 and twists, changing direction and deflecting towards the lateral surface of the chamber. In this case, the suspended particles are separated from the flow and are deposited in the peripheral part of the chamber on the partition 3. The partially clarified fluid flow along the guide surface of the upper cone 8 of the element 6 enters through the opening 4 into the next cleaning chamber, where the separation of suspended particles is repeated. Similar fluid treatment occurs during

To remove sediment in the apparatus, its periodic washing is provided. In the washing mode, the locking elements 17 and 18 on the washing water line are opened and the locking elements 15 and 16 are closed.

In each chamber 5, coaxially guiding elements 6 are arranged coaxially with holes 4 in the form of two cones connected by bases. The lower cone 7 has a taper angle of 70-95 ° and serves as a fender surface, and the upper cone 8 has a sharp

The quality of cleaning of the proposed apparatus allows to increase the speed of water treatment from 0.5-0.7 mm / s to 3-4 mm / s and, accordingly, increase productivity by 4-6 times. Efficiency, equal to 70-100%, was achieved when the separation of particles with a size of 0.2-0.8 mm at a taper angle from the outgoing pipe 14 of the treated water. In the inlet and outlet pipelines, locking elements 15-18 are installed.

The device works as follows.

In operation, the locking elements 15 and 16 on the pipelines 12 and 14 are open, and the locking elements 17 and 18 are closed.

The liquid to be purified is fed through conduit 12 to the lower part of housing 1, to the first cleaning chamber 5 from below. At the entrance to the chamber, a stream of fluid meets in its path the baffling surface of the cone 7 of element 6 and twists, changing direction and deflected to the side surface of the chamber. In this case, the suspended particles are separated from the flow and are deposited in the peripheral part of the chamber on the partition 3. The partially clarified fluid flow along the guide surface of the upper cone 8 of the element 6 enters through the opening 4 into the next cleaning chamber, where the separation of suspended particles is repeated. Similar fluid treatment occurs during
