Efficient backwashing type water purifier

Abstract

The invention discloses an efficient backwashing type water purifier, and belongs to the field of water purification. The efficient backwashing type water purifier comprises a total water inlet pipe,which is divided into two branches, wherein one branch is a purified water inlet pipe, the water inlet pipe is connected to the upper end of a filtering chamber, the other branch is a backwashing water inlet pipe, the backwashing water inlet pipe is connected to the lower end of the filtering chamber, a back flushing sewage discharge pipe is positioned between the water inlet pipe and the filtering chamber, and is positioned on the outer side of a shell, a filtering material is arranged inside the filtering chamber, the lower portion is provided with a water outlet hole, and a water outlet pipe is positioned below the filtering chamber. According to the present invention, the design is reasonable; and by separately arranging the backwashing water inlet pipe, the back flushing force is increased by using the pressure of the tap water pipe, such that the pollutants trapped in the filtering material are completely discharged, the replacement of the filtering material during the use is notrequired, the recovery degree of the filtering material is high, and the service lives of the filtering material and the purifier can be easily prolonged.

Description

technical field [0001] The invention belongs to the technical field of filtration and purification, and in particular relates to a high-efficiency backwashing type water quality purifier. Background technique [0002] Existing residential water is usually transported to users by waterworks through large, medium and small water delivery pipelines. Finally, the quality of tap water used by users is often poor. The reason is that, on the one hand, most of the source water is polluted to varying degrees due to the discharge of industrial waste water, waste gas, and pesticides. During the water delivery process, the rust and deposited pollutants in the water pipes cause secondary pollution to the tap water, further deteriorating the water quality and affecting people's drinking water health. [0003] Therefore, at present, whether it is a family, an enterprise or a school, etc., water purification devices are widely used to improve water quality and reduce and prevent pollution...

AI Technical Summary

Problems solved by technology

Some purifiers do not have a backwash function. After the filter element or filter material is used for a period of time, the trapped pollutants accumulate and cause the blockage of the filter element or filter material, which will reduce the water quality and water output.

In this case, if it is not replaced in time, it will aggravate the pollution of water and cause negative effects, and sometimes even the water cannot be discharged; if the filter element or filter material is replaced frequently, it is very troublesome; although some purifiers are equipped with backwashing function , but the recoil force is too small to discharge the trapped pollutants cleanly
