Abstract
The invention discloses a diatomite filter core for water purifier. The filter core comprises a PP cotton cylinder; the external surface of the PP cotton cylinder is wrapped by a diatomite layer and a PP cotton coating, the thickness of the diatomite layer is 2 to 10 mm, and the particle size of diatomite of the diatomite layer is 30 to 40 [mu]m. The diatomite is directly wrapped between two layers of PP cotton, so the diatomite layer does not to be adhered by an adhesive, and the diatomite layer is not coated by an adhesive. During the application process, the diatomite layer can fully contact the water body, and the absorption performance of the filter core is greatly improved. The wrapping of the active carbon layer is carried out through a physical technology, no chemical agent is used, so the environment is not polluted and the production cost is reduced. Besides, the diatomite is neutral and non-toxic, the absorption performance of the diatomite is strong, the unit weight of the diatomite is light, the characteristics of diatomite are utilized, the diameter of the micropore is only 0.5 [mu]m, and thus an ultrafiltration effect can be achieved, so the water purification effect of the diatomite is better than that of conventional active carbon.
