Problems solved by technology

However, due to the relatively large pore size, its interception effect is limited, and the activated carbon particles will gradually penetrate and block the filter layer of the above-mentioned fine filter element, resulting in clogging and affecting the life of the filter element.
In the same way, the post-installed activated carbon filter element behind the fine filter element also has the phenomenon of "running charcoal", and even flows out with the treated clean water, directly affecting the quality of drinking water
Although the fine activated carbon that "runs out" does not have a qualitative impact on the quality of direct drinking water, these black particles directly affect the "visual" effect of purified water, causing adverse reactions far beyond imagination
Because the existing water purifier lacks the device for cleaning the above-mentioned microfiltration grade fiber or ceramic filter element, even if the microfiltration grade filter element is placed under the tap to rinse, the tap water will only flow along the surface of the filter element and cannot pass through the filter layer. The cleaning effect is very little, let alone enter the filter layer in reverse, and flush out the impurities in reverse
Above-mentioned defect and deficiency cause water purifier to be difficult to obtain wider popularization

Embodiment Construction

[0031] The accompanying drawings show the best implementation of the present invention. The tap water of the pipeline enters from the water inlet 9 of the box-type machine base 6, and the water inlet of the fixed filter case 1a, the pipe walls of the front and rear fiber filters 4a, 4b, 4c are fixed through the combined filter chamber 1, and the other water port of the fixed filter case 1a is fixed. And the second, third, fourth, fifth stage filter element 7a, 7b, 7c, 7d, finally flow out by the water outlet 5. In the rear combination filter cavity 1, water enters the inside through the pipe wall from the outside of the tubular filter gall 4c and flows out from another water port of the fixed filter housing 1a, the machine water outlet 5. After the machine has been running in the filtering mode for a period of time, impurities are accumulated on the inner and outer sides of the two filter galls 4a, 4b in the front combined filter cavity, and on the outer side of the filter gal...

Abstract

The invention relates to the water treatment industry, in particular to depth type filtration and purification of the drinking water. The invention discloses a method for cleaning filter liners of built-in and combined filter chambers of a water purifier. The device comprises filter elements, a base with water inlet and outlet, a filter channel connecting the filter elements and the water inlet and outlet of the base in series, the combined filter chambers formed by a fixed filter shell, a movable chamber cover and a sealing element and the tubular filter liners, wherein the combined filter chambers form a whole with the base and are provided with two water gaps of the filter liners side by side and two filter liner riding positions; the filter liners are positioned in the combined filter chambers and are connected with the combined filter chambers in series in the filter channel; and forward and reverse single water channels of the filter liners under fixed mode of the water inlet and outlet are respectively formed by translating and changing the riding positions of the filter liners. The invention has simple and practical structure and good filtering and backflushing effects, effectively eliminates the effect of carbon permeation on the drinking water, is convenient and timely in cleaning and replacing the filter liners and ensures the subsequent filter elements to have long service lives.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] At present, water purifiers are relatively popular in China. When drinking water is used, the water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. The "pollution" degree of the filter element impurities exceeds the "pollution" degree of the drinking water itself, so that the filter element becomes a ne...
