KDF ultra-filter membrane water purifier having dust shield cover and manufacturing method thereof

Abstract

A KDF ultra-filter membrane water purifier having dust shield cover and a manufacturing method thereof. A screw hole, which is fixed to the dust shield cover, is arranged on the top of an upper valve base. A screw inner thread opening is arranged in a lower opening of the upper valve base. A screw outer thread opening and a first silica gel sealing ring are arranged in an upper opening of a cylinder body. An upper circular clamping tube, in which a middle connection pipe is inserted, is disposed on the center of the upper valve base. A lower circular clamping tube is arranged on the bottom of the cylinder body. The middle connection pipe is fixed effectively with the upper circular clamping tube and the lower circular clamping tube. A filter part, which is composed of a filter core shell and a plurality of filter layers, sleeves the upper part of the middle connection pipe. A second silica gel sealing ring is arranged in a groove in the outer wall of the filter core shell. A far infrared mineralized stone filter layer, a KDF filter layer, a residual chlorine purifying stone filter layer and a fiber filter layer are arranged in the filter core shell from bottom to top successively. An ultra-filter membrane filter core sleeves the lower part of the middle connection pipe. A water inlet is arranged on the left side of the upper valve base and a water outlet is arranged on the right side of the upper valve base. The water outlet of a high-precision PP fiber cotton filter apparatus is communicated with the water inlet of the KDF ultra-filter membrane apparatus. The water purifier is economical and practical.

Description

technical field [0001] The invention relates to water treatment equipment, especially the manufacturing field of drinking water purifiers for urban and rural households. Background technique [0002] According to the survey of the World Health Organization, 80% of human diseases are related to water. The main disinfection method of tap water is chlorination. Although it can remove a large number of bacteria, there are also harmful substances, especially heavy metals, chlorine molecules and nitrite in water. Ingredients, transportation process and water tower storage will cause a certain degree of secondary pollution. Although the water is boiled, harmful substances such as heavy metals in the water cannot be removed. Excessive intake of these substances can cause great harm to the human body and threaten For human health, tap water in urban and rural areas exceeds the standard and cannot meet the "Drinking Water Hygienic Standards" of the People's Republic of China. The abov...
