Integrated composite filter element for water purification

Abstract

The invention discloses an integrated composite filter element for water purification, which comprises a filter bottle body and a base at the lower end of the filter bottle body, wherein a water inletend, a water outlet end and a rear activated carbon filter layer are arranged at the upper end of the filter bottle body; a filter element bottom cover, a filter element upper cover and a multi-stagefilter layer are arranged in the filter bottle body, and a rotary core body is arranged on the inner wall of the bottle body; the first-stage filter layer comprises PP cotton and front activated carbon, and the second-stage filter layer is a reverse osmosis membrane; the third-stage filter layer is made of rear activated carbon; and the rear activated carbon is arranged in an end cover at the upper end of the filter bottle body. The integrated composite filter element effectively improves the water purification efficiency, solves the problem of slag falling of activated carbon particles, is compact in structure and sufficient in filtration, and reduces the size and the manufacturing cost of a water purifier.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to the field of an integrated composite filter element for water purification. Background technique [0002] Nowadays, fresh water resources are scarce. If the existing water resources are not rationally utilized, the situation of water resource shortage will become more severe as the population of our country increases. The state has invested huge sums of money in the south-to-north water diversion project and seawater desalination project to balance water resources. As a citizen, saving water resources is even more of a responsibility. Therefore, while saving water, how to ensure water quality has become a top priority. [0003] The water purifier with the reverse osmosis film (Reverse osmosis film) as the core can intercept and remove harmful substances such as insect eggs, bacteria, and viruses in tap water, and the obtained pure water can be directly drunk. The main filter com...

Problems solved by technology

The main filter components of pure water machines sold on the market are PP cotton, granular activated carbon, compressed activated carbon, ultrafiltration membrane (hollow fiber membrane) and reverse osmosis membrane, but the problem is that the filter elements at all levels will reduce the volume of the water purifier. Larger and more complex, there are many keys and valve switches connected to each other, and there are hidden dangers of water leakage

And granular activated carbon is prone to fall off and collapse during use, resulting in secondary black water, thus affecting the quality of filtered water

[0004] In addition, after the tap water enters the filter bottle equipped with PP cotton in the first stage, the PP cotton needs a certain period of time to wait for the water pressure to stabilize before it can start to filter efficiently, and when the tap water quality is poor, the large particles contained in the water will shorten the life of the PP cotton. service life
