technical field

The utility model belongs to the technical field of fresh water purification, in particular to a nuclear pore membrane supporting device and a nuclear pore membrane filter comprising the nuclear pore membrane supporting device.

Background technique

Water is the source of life and the material basis for human to maintain metabolism. Natural water is most suitable for human consumption because of its moderate amount and proportion of minerals and trace elements. Judging from the standards set by the World Health Organization, plain water formed after boiling and cooling natural water is the healthiest drinking water. However, scale problems inevitably exist in boiled water.

Scale is originally the sediment of heavy metals, calcium salts, magnesium salts, dust, germs, insect eggs, etc. mixed in water. It is not only unhygienic, but also seriously affects people's health. In order to remove scale, people use nuclear pore membranes to make drinking water filtration devices. Scale can be effectively removed by using a nuclear pore membrane filter.

The nuclear pore membrane is to use the high-energy particles accelerated by the accelerator to penetrate the plastic film, leaving a narrow radiation operation channel-track on its path. Etching with appropriate chemical reagents can etch the track on the film into cylindrical micropores, and control the irradiation conditions and etching conditions to obtain nuclear pore membranes with different pore densities and pore sizes.

In the existing nuclear pore membrane filters on the market, the support of the nuclear pore membrane is usually a flat plate with small holes. As shown in Figure 1, drinking water passes through the small holes on the support after being filtered by the nuclear pore membrane. 11 outflow, because the part 12 that does not have the small hole on the support will hinder the outflow of drinking water, so the filtering efficiency of the existing filter is relatively low. The utility model is designed at above-mentioned defect.
