Water purification equipment

Abstract

The invention relates to water purification equipment, which comprises a filtering barrel, wherein the top of the filtering barrel is connected with a water inlet, the bottom of the filtering barrel is connected with an outflowing water storage tank; a first filter screen, a second filter screen and a third filter screen are arranged in the filtering barrel; a first filtering cavity is formed between the first filter screen and the top of the filtering barrel, a second filtering cavity is formed between a first filter screen and the second filter screen, a third filtering cavity is formed between the second filter screen and the third filter screen, the first filtering cavity is filled with activated carbon particles, the second filtering cavity is filled with nanosphere particles, the third filtering cavity is filled with polyiodide resin particles; two ends of the first filter screen, the second filter screen and the third filter screen are respectively connected with a driving component; the driving components are fixedly arranged on the inner wall of the filtering barrel; a plurality of flushing mechanisms are arranged on the lower sides of the first filter screen, the second filter screen and the third filter screen, so that the purification quality is guaranteed and the service life of the water purification equipment can be prolonged.

[0002] For life, water is indispensable, and humans are no exception. In extreme environments, the human body may become metabolically disordered beyond rescue if it lacks water for 24 hours; even under relatively comfortable conditions of temperature, humidity, and air pressure, a It is difficult for an adult to last for more than 5 days without water intake. The common process of nanofiltration or reverse osmosis water purifiers in the past is non-woven fabric, coarse filter granular activated carbon (GAC), fine filter granular activated carbon, ultrafiltration membrane, nanofiltration Membrane or reverse osmosis membrane and post granular activated carbon, a major hidden danger of this kind of water purifier is that if the water purifier has not been used for a period of time, or just for one night, the outlet and rear of the water purifier A large number of bacteria will grow inside the granular activated carbon filter, making the total number of colonies in the effluent not meet the requirements of GB5749-2006. Due to the porous characteristics of the rear granular activated carbon, it is very conducive to the growth of bacteria. After the water flows through the water purifier, the activated carbon While sterilizing the water, it will also bring out the bacteria carried by the activated carbon itself, causing secondary pollution. This is a common problem in all water purifiers sterilized by activated carbon.

[0003] In order to overcome the problem of secondary pollution caused by activated carbon sterilization, water purification technologies such as ultraviolet sterilization and ultrafiltration sterilization have appeared on the market. Although this sterilization effect is better than activated carbon, no matter what kind of water purifier, the final terminal There will still be the problem of excessive bacteria in the effluent, and it will inevitably cause the structure and process of the water purifier to become more complicated, the manufacturing cost will rise sharply, the power consumption will increase, and the service life of the water purifier will be shortened
