Abstract

The invention provides a novel energy backwashing filter, belongs to the technical field of filter machines, and particularly relates to a backwashing filter. A technical means adopted to solve the technical problem is as follows: the novel energy backwashing filter comprises a filtering system and a dreg collecting device, wherein the filtering system comprises a vacuum drum, first filter cloth and second filter cloth, one end of the first filter cloth bypasses the vacuum drum and a plurality of first guide rollers and then is connected with the other end of the first filter cloth to form an enclosed ring, one end of the second filter cloth bypasses the vacuum drum and a plurality of second guide rollers and then is connected with the other end of the second filter cloth to form an enclosed ring, and part of the second filter cloth in contact with the vacuum drum covers the first filter cloth to form a filter interlayer; the dreg collecting device can classify dregs filtered by the filter cloth by particle sizes, secondarily purify residual water, and recover and utilize the dregs. The practical effect is good.

Description

technical field [0001] The invention relates to a new energy backwashing filter, which belongs to the technical field of filtering machinery, and in particular relates to a backwashing filter. Background technique [0002] Backwash filters have been gradually used in mineral processing, mineral processing, water treatment, paper industry, petrochemical industry, municipal or agricultural irrigation and other industries in recent years. [0003] When the backwash filter works, the liquid to be filtered enters the filter from the inlet, and then passes through the filter screen from the inside to the outside. After filtering for a long time, some impurities accumulate on the inner surface of the filter screen, causing a certain loss of water pressure. When the pressure difference inside and outside the filter reaches the threshold value set for cleaning or reaches the cleaning time set by the user according to the water quality, the drain valve at the bottom of the backwash f...
