Purification components and water purifiers

Abstract

The invention discloses a purification component comprising an electrocoagulation device, a sewage channel and at least two filtering units, and each filtering unit is provided with a first opening and a second opening; each filtering unit has at least two working states, when any filtering unit is at a water production state, the first opening of the filtering unit is communicated with the water outlet end of the electrocoagulation device; when any filtering unit is at a back wash state, the first opening of the filtering unit is communicated with the sewage channel, and the second opening of the filtering unit is communicated with the second opening of the filtering unit is at the water production state. The purification component disclosed by the invention adopts the above structure, the filtering unit at the downstream of the electrocoagulation device can not only produce water, but also can discharge flocculent colloid therein from the filtering unit by back wash, so as to avoid residual flocculent colloid in pure water and avoid the flocculent colloid of blocking the components at the downstream of the electrocoagulation device.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a purification assembly and a water purifier. Background technique [0002] Water purifiers are widely used as a common household water treatment device at present. The water purifier can remove bacteria, viruses, heavy metals, salt and other impurities in the water through the filter device, so as to obtain relatively pure pure water. [0003] In industrial water purification treatment devices, electrocoagulation devices are often used to remove impurities such as heavy metals and salt in water. The electroflocculation device uses aluminum, iron and other metals as anodes. Under the action of direct current, the anodes are eroded to produce Al and Fe plasmas, which develop into various hydroxyl complexes through a series of hydrolysis, polymerization and oxidation processes of ferrous iron. , polynuclear hydroxyl complexes and even hydroxides, so that the colloidal impurities and su...

Problems solved by technology

[0004] However, there are often flocculent colloids in the water filtered by the electrocoagulation device. These flocculent colloids will not only affect the water quality of pure water, but may also block the pipes or components after the electrocoagulation device.

Therefore, existing water purifiers generally do not include electroflocculation devices
