Water purifier with reverse-flushing pollution discharge function and manufacturing method

Abstract

The invention discloses a water purifier with a reverse-flushing pollution discharge function and a manufacturing method. The water purifier comprises a multifunctional composite filter material filtering layer. A circular hole is formed in the top of a closed container of a filtering device. A filter element composed of a built-in filter element shell and a filter layer is fixed to the circular hole. The multifunctional composite filter material filtering layer, a granular magnet magnetizing layer, a medical stone mineralizing layer and an activated aluminum oxide filtering layer are arranged in the filter element shell. PP fiber cotton filter elements are arranged on the left side and the right side of the lower portion of an annular sieve plate. Supporting frames for fixing the filter elements are arranged on the left side and the right side of the lower portion of the sieve plate. A clamping assisting spring is arranged on each supporting frame. Annular clamping pipes are arranged on the left side and the right side of the bottom of the filter element shell. The annular clamping pipes and the clamping assisting springs can effectively fix the PP fiber cotton filter elements through compression springs. A water inlet is formed in the top of the container. A water outlet is formed in the right side of the lower portion of the container. The water outlet of the filtering device is communicated with the water inlet of a water purifying tower. The water purifier is economical and practical.
