Portable bottle cap type water purification device

Abstract

The invention discloses a portable bottle cap type water purification device which is characterized in that a shell comprises a water inlet shell and a water outlet shell which are connected with each other in a threaded manner, the sizes of threads of a water inlet and a water outlet at two ends of the shell are matched with those of threads of a plastic drinking water bottle opening and a cap to be connected, a water purification process layer is formed by sequentially overlapping a PP (polypropylene) cotton layer, a flaky urchin-like hydroxyapatite bionic nano-material layer, flaky activated carbon and an ultra-filtration membrane and fixedly packaged in the bottle cap through a screen baffle plate at a water inlet end, the flaky urchin-like hydroxyapatite bionic nano-material layer takes a hydroxyapatite material as a substrate and is synthesized by a hydrothermal method, and the substrate is modified with flaky or urchin-like nano-absorption metal oxide materials. The device is simple, portable, capable of filtering organic matters, heavy metal ions, bacteria, viruses, algae and the like, and applicable to meeting the requirement for clean drinking water under emergency situations of field forces, field workers, outdoor adventure, travel and rescue and relief work, and water can be purified and instantly drank.

Description

technical field [0001] The invention belongs to the technical field of water purification materials and water purification equipment, and in particular relates to a bionic nanometer water purification material and a bottle cap type portable water purification device. Background technique [0002] Generally, field workers and emergency rescuers require water purifiers that are small in size, light in weight, easy to carry, capable of processing water sources such as rivers, lakes, ponds, and other water sources. ” or “Sanitary Standards for Drinking Water in Military Wartime”. However, the current traditional drinking water treatment requires processes such as dosing, coagulation, clarification, filtration, and disinfection. The process is complicated, the equipment is cumbersome, and drinking water often has peculiar smell. Chinese patent CN2900496Y discloses a portable water purifier weighing about 200 grams. In the cavity, ion exchange resin, activated carbon and hollow f...

AI Technical Summary

Problems solved by technology

Although the ultrafiltration membrane can effectively filter out bacteria and reduce the turbidity of the effluent, the use of activated carbon prolongs the service life of the membrane, the effluent is relatively stable and the water quality meets the drinking water standard of the army during wartime, but its filter material is easy to clog

[0003] There is also a portable field water purifier as provided by Chinese patent CN99247796.4, including a raw water tank and a clean water tank installed in the casing, and parts such as a coarse filter plate and a filter water tank are installed. This water purifier has a complex structure and takes up space. Large, cannot meet the portable needs of field workers, and the water purification process needs to wait, which cannot meet the water purification needs in emergency situations

In addition, common water purification devices mostly use tap water, lakes, oceans, etc. as water sources. The design principle has a weak effect on the removal of heavy metals, and the selection of water sources is narrow.
