Problems solved by technology

This flushing method has a simple structure, but the cleaning effect is limited. After flushing, the ultrafiltration membrane filter element is still not clean enough, and there is a problem of incomplete flushing.
Because some stubborn stains deposited and adhered in the membrane filaments are difficult to be cleaned thoroughly, over time, the accumulated and adhered stains in the membrane filaments will accumulate more and more, which will affect the purification efficiency of the ultrafiltration membrane filter element, and even in severe cases. This leads to complete blockage of the membrane filaments, resulting in a smaller flow of purified water, or even failure
[0004] It can be seen that the flushing effect of the existing flushing method on the ultrafiltration membrane filter element is not ideal, which affects the purification efficiency, and easily leads to the clogging of the ultrafiltration membrane element, and the service life of the ultrafiltration element is relatively short

no. 1 Embodiment

[0038] See Figure 1 to Figure 5 , The water purifier provided by the first specific embodiment of the present invention includes a housing 8, a filter element 6 and a rotating impeller 4. in:

[0039] The filter element 6 is installed in the housing 8 and is composed of a plurality of membrane filaments 9 for filtering and producing purified water;

[0040] The upper cover of the housing 8 is provided with a water inlet 3 and a fixed column 2, and the fixed column 2 is located on the inner side of the upper cover and is fixedly connected with it;

[0041] The rotating impeller 4 is rotatably installed on the fixed column 2 and is located between the water inlet 3 and the water inlet end of the filter core 6, and the blades in the rotating impeller 4 are all inclined blades.

[0042] Wherein, the aforementioned inclined blade means that the central plane of the blade is inclined at a certain angle relative to the plane perpendicular to the central axis of the fixed column 2 ...

no. 2 Embodiment

[0064] The difference between the water purifier provided by the second embodiment of the present invention and the water purifier in the first embodiment of the present invention is only that the elastic member 403 and the connecting sleeve 402 are arranged above the bearing 401. For details, please refer to Figure 6 , one end of the elastic member 403 is fixedly connected with the inner ring of the bearing 401 , and the other end is fixedly connected with the shaft shoulder of the fixed column 2 .

no. 3 Embodiment

[0066] The difference between the water purifier provided by the third embodiment of the present invention and the water purifier in the first embodiment of the present invention is only that the elastic member 403 and the connecting sleeve 402 are arranged above the bearing 401. For details, please refer to Figure 7 , one end of the elastic member 403 is fixedly connected with the inner ring of the bearing 401 , and the other end is fixedly connected with the inner side of the housing 8 .

Abstract

The invention discloses a water purifier, which relates to the technical field of water purification. The water purifier comprises a shell, a filter element and a rotary impeller, wherein the filter element is installed in the shell and used for generating purified water; an upper cover of the shell is provided with a water inlet and a fixing column, and the fixing column is located on the inner side of the upper cover and fixedly connected with the upper cover; the rotary impeller is rotatably mounted on the fixing column and located between the water inlet and the water inlet end of the filter element, and blades in the rotary impeller are inclined blades. When the water purifier is used for cleaning the filter element, pulse type flushing water flow can be generated by rotating the impeller, so that the filter element can be better cleaned, the cleaning efficiency is improved, the filter element is prevented from being blocked, and the service life of the filter element is prolonged.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purifier. Background technique [0002] The ultrafiltration membrane filter element in the ultrafiltration central water purification product (that is, the ultrafiltration membrane water purifier) ​​is a water purification filter element made of hollow fiber membrane silk. Among them, the membrane silk is a kind of hollow fiber membrane, which can filter impurities in the water, and the tap water enters the inside of the membrane silk and permeates outward to produce purified water. [0003] Ultrafiltration membrane water purifiers usually adopt the dead-end filtration method, which needs to be flushed in a timely manner during normal use to achieve the purpose of cleaning the membrane filaments. The traditional method of flushing the ultrafiltration membrane filter element is that the flushing water flow is directly injected into the end face of the ultrafilt...
