High-efficiency drum-type unpowered self-cleaning water filtering device

Abstract

The invention discloses a high-efficiency drum-type unpowered self-cleaning water filtering device. The high-efficiency drum-type unpowered self-cleaning water filtering device is characterized by mainly comprising a drum (1), a water collecting pond (2) and a sewage collecting cover (3); the water collecting pond ()2 is mounted in the drum (1) so as to collect water filtered by the drum (1) and leads the water into subsequent treatment equipment; the sewage collecting cover (3) is mounted at the lower part of the drum (1) and is used for collecting particles which are thrown into the drum (1) from the surface of the drum (1) because of centrifugal force; a filtering net (4) covers the surface of the drum (1) and is used for filtering the particles with set particle sizes in the water which is required to be treated; driving plates (5) are mounted on the drum (1) at intervals; the water to be treated impacts the driving plates (5) to generate driving force to drive the drum (1) to rotate at a high speed; the water to be treated falls into the water collecting pond (2) through the filtering net (4) between every two adjacent driving plates (5); the particles which are filtered out by the filtering net rotate to a disengagement position under the action of the centrifugal force, impact the sewage collecting cover and are collected by the sewage collecting cover. The high-efficiency drum-type unpowered self-cleaning water filtering device can realize infinitely cyclic continuous work and is not required to be driven by power; the filtered impurities are collected by the collecting cover under the action of the centrifugal force.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a particle filtering device in water, in particular to a high-efficiency drum type non-powered self-cleaning water filtering device. Background technique [0002] At present, in water treatment, it is generally necessary to clean up the particles in the water first, and then perform fine treatment or chemical treatment. However, most of the existing particle treatment devices need to carry out regular backwashing to remove the impurities or particles blocked on the filter screen, so as to ensure the normal operation of the follow-up filtration work, which leads to the interruption of normal filtration work and requires a lot of waste. For backwash water, if it is to run uninterruptedly, it is necessary to set up a backup filter device. Contents of the invention [0003] The purpose of the present invention is to design a drum-type non-powered water filter device that can filter an...
