Abstract
The invention discloses a domestic water purifier with a graded drainage function and a manufacturing method of the domestic water purifier. The domestic water purifier comprises a water supply pump, an elevated impounding tower, a pure water tank, a manual graded drainer, a multi-medium filtering device and an antibacterial descaling device. The domestic water purifier is characterized by further comprising a nanofiltration membrane filtering device, wherein an inner screw hole which is screwed with a shell is formed in an upper end seal of a nanofiltration membrane shell; an outer screw hole which is screwed with the upper end seal is formed in the upper end of the shell; a nanofiltration membrane filter element is arranged in the middle of a sealed container; a water inlet is formed in the bottom of the nanofiltration membrane shell; a water outlet is formed in the right side surface of the upper part of the nanofiltration membrane shell; the water outlet of the antibacterial descaling device is communicated with the water inlet of the nanofiltration membrane filtering device. The domestic water purifier is economic and practical, and can provide qualified and healthy living drinking water for rural families.
Description
technical field [0001] The invention relates to the field of water purification equipment, especially the manufacture of drinking water purifiers for rural households. Background technique [0002] The increasing pollution of modern water resources has the most serious impact on rural areas. Basically, farmers and enterprises and institutions with good conditions dig wells for drinking water, and unconditional ones use pipe networks to directly drink water in rivers and ravines. At present, 92 More than 100% of rivers and groundwater are polluted, even seriously polluted, and the pollution is even more heinous, especially groundwater iron, manganese, alkali, chlorine, suspended solids, colloids, toxic by-products, pesticides, bacteria, sediment, rust , Solid impurity pollution hazards, even if there is well water, it is seriously over the standard, undrinkable, threatening the health of human beings. Rural retail households, enterprises and institutions living in rural area...
