Abstract

The invention discloses a flushable external pressure type ultrafiltration filter core assembly. The ultrafiltration filter core assembly comprises a filter shell and a filter core arranged in the filter shell, one end of the filter shell is a water inlet end, the other end of the filter shell is a water outlet end, a raw water total inlet is arranged at the water inlet end of the filter shell, a purified water total outlet and a dirt total outlet are arranged at the water outlet end of the filter shell, the filter core comprises a water purifying chamber formed in the filter shell and hollow fiber ultrafiltration membrane filaments placed in the water purifying chamber, a wall of the water purifying chamber is provided with a raw water inlet communicated with the raw water total inlet, a purified water outlet communicated with the purified water total outlet and a dirt outlet communicated with the dirt total outlet, a tube port at one end of the hollow fiber ultrafiltration membrane filaments is sealed, a tube port at the other end of the hollow fiber ultrafiltration membrane filaments is communicated with the purified water outlet, and the filter core is rotatablely arranged in the filter shell. The flushable external pressure type ultrafiltration filter core assembly has a good flushing effect and can effectively increase the total purified water amount. The invention also discloses a water purifier using the flushable external pressure type ultrafiltration filter core assembly.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a flushable external pressure ultrafiltration element assembly and a water purifier using the flushable external pressure ultrafiltration element assembly. Background technique [0002] At present, the ultrafiltration filter element is divided into two types: internal pressure type and external pressure type. The internal pressure ultrafiltration filter element has a flushable structure, can be washed repeatedly, and has a long service life; however, the internal pressure ultrafiltration filter element is prone to bursting, and the safety of drinking water cannot be fully guaranteed. The external pressure ultrafiltration filter element has no danger of membrane filament breakage, but it does not have a flushable structure, or it needs to be equipped with a recoil valve and electric control to flush, while the ultrafiltration membrane only needs sufficient water pressure to work. It se...
