A self-flushing water purifier

Abstract

The invention relates to the technical field of water treatment, and particularly relates to and discloses a water purifier capable of automatically washing. The water purifier comprises at least one ultrafiltration element, an activated carbon filter element and an end cover, wherein water inlets and water outlets of the ultrafiltration element and the activated carbon filter element are positioned at the same end of the filter element bodies; a general water inlet, a pure water outlet and a washing outlet are formed in the upper top part of the end cover; a water inlet interface, an ultrafiltration element interface, an activated carbon interface, a water outlet interface and a washing interface are formed in the lower top part of the end cover; the general water inlet is connected to the ultrafiltration water inlet by virtue of the water inlet interface; the ultrafiltration water outlet is sequentially connected with the ultrafiltration element interface, a connecting pipe, the activated carbon interface and a water collecting inlet; a water collecting outlet is connected with the pure water outlet by virtue of a water outlet interface; a water distribution hole of the ultrafiltration element is communicated with the washing outlet by virtue of the washing interface; and switches are respectively arranged at three end openings in the upper top part of the end cover. The water purifier is prevented from growth of bacteria and microbes, can be used for producing domestic water, and cannot waste the water resource.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a self-flushing water purifier. Background technique [0002] At present, ultrafiltration membranes in the water treatment industry are mainly cleaned in two ways. The first is to soak the ultrafiltration membrane with chemical agents by chemical means, so that the chemical reaction between the medicine and the dirt on the surface of the ultrafiltration membrane can be achieved, so as to achieve the cleaning effect. The disadvantage is that the cleaning time is long, and multiple cleanings have a great impact on the life of the ultrafiltration membrane; the second is through physical means, namely forward washing and backwashing. The effect of this cleaning method is poor, and the flux recovery of the ultrafiltration membrane is less after cleaning, but the impact on the life of the ultrafiltration membrane is relatively low. Chemical means are not suitable for domestic...
