Description

a water purification device

technical field

The utility model relates to the field of environmental protection, in particular to a water purification device.

Background technique

With the development of economy and the improvement of living standards, people have higher and higher requirements for the quality of drinking water. The tap water that enters thousands of households is generally the drinking water produced by the flocculation-precipitation-filtration-chlorine disinfection process in the waterworks. Despite many processes of purification and disinfection, due to purification efficiency and artificially added disinfectants, the drinking water used by consumers still contains some chemicals such as sediment, tiny humus, soluble organic matter and disinfectants. In addition, with the passage of time, secondary pollution caused by outdated and aging urban water transmission and distribution pipeline networks has become increasingly apparent. The most common sources of pollution are rust, sediment, and microorganisms. Therefore, using a suitable household water purifier is undoubtedly an economical, convenient and fast way for families to obtain safe and healthy drinking water.

Faucet water purifier refers to a miniature water purification device/equipment that is directly installed and suspended from household faucets. Faucet water purifiers are favored by consumers because of their low price, simple installation and maintenance procedures, and rapid water quality improvement. Ceramic and composite filter media technology is the more commonly used water purification technology. The steps of using this technology to treat sewage are as follows: directly pass the sewage into the hollow shell, so that the sewage is in direct contact with the filter element.

However, when the sewage enters the shell, the tap water will automatically choose the shortest path to flow through the filter element under the action of pressure and gravity, and the bottom of the filter element (the water treatment material near the water outlet will absorb harmful substances first, and also the water at the bottom). The treatment material first reaches the saturated adsorption capacity and fails. When used for a period of time, the water treatment material under the filter element will reach the state of adsorption saturation in advance, while the water treatment material located above the filter element has almost no filtering effect. After the water treatment material under the filter element is blocked by insoluble matter in the water, the water purification point of the water treatment material that plays a role of adsorption will gradually move up. After the tap water is purified, the purified water still needs to flow through the water treatment material under the filter element. Outflow, which will cause secondary pollution. At the same time, because the water treatment material under the filter element is blocked, it is very likely that the flow of purified water is too small or blocked.

Subsequently, since the connection point between the fixing sleeve and the outer filter layer is between the upper and lower end faces of the first inner filter layer, the sewage is first contacted and filtered with the first inner filter layer, and then will be filtered due to gravity. Flow down, into the second inner filter layer. After the sewage is filtered by the second inner water filter layer, pure water can flow out. In the above process, since the tap water passes through different water treatment materials, it can effectively prevent the situation that the local water treatment materials do not participate in water purification, which not only improves the water treatment efficiency, but also prevents the water treatment materials located at the bottom of the shell. Due to the first adsorption and saturation, after the purified water flows through, secondary pollution occurs.
