Water purification system with self-cleaning filter element

Abstract

The invention discloses a water purification system with a self-cleaning filter element. The water purification system comprises a hollow shell, the upper end of the shell is communicated with a firstraw water pipe and a second raw water pipe, the first raw water pipe and the second raw water pipe are both communicated with an external water pipe, a filter element of an annular structure is arranged in the shell, and the first raw water pipe and the second raw water pipe are located on the inner side and the outer side of the filter element respectively; the lower end of the shell is communicated with a living water pipe and a purified water pipe; the purified water pipe and the living water pipe are respectively positioned on the inner and outer sides of the filter element; the first rawwater pipe is located in the center of the shell, and the lower end of the first raw water pipe is fixedly connected with a fixed barrel. The water purification system has the advantages that the spiral guide plate is arranged on the inner wall of the first raw water pipe, when water in the first raw water pipe flows through the spiral guide plate, the water flowing into the fixed barrel rotates,the rotating water flushes the filter element, and the situation that the filter element is not flushed cleanly due to some flushing dead angles is avoided.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification system with self-cleaning filter elements. Background technique [0002] With the deterioration of the environment, the cleanliness of water sources has become lower and lower, and urban water needs to be treated and purified to meet the use standards; at the same time, people's requirements for drinking water are getting higher and higher, and more and more families Buy a water purifier to purify the water quality; common water purifiers are divided into one inlet and one outlet, one inlet and two outlets, and one inlet and two outlets. The water purifier uses domestic water pipes to clean the filter element, which seems advanced and scientific. But it can only clean the surface of the filter element, and cannot do deep cleaning; [0003] During the use of the filter element, it is inevitable that there will be a lot of local dirt. The self-clean...
