Portable reverse osmosis water filter device

Abstract

The invention discloses a portable reverse osmosis water filter device which comprises a pretreatment device and a reverse osmosis filter device, wherein the pretreatment device is a sand filter device which is communicated with an activated carbon filter device through a hose, the activated carbon filter device is communicated with a tank through a hose, the tank is communicated with a human power driven pump through a hose, and the human power driven pump is communicated with the reverse osmosis filter device through a pressure hose; an inner cavity of the tank is cuboid, a tank cover is arranged, and positioning grooves for storing the sand filter device, the activated carbon filter device, the human power driven pump, the reverse osmosis filter device, the hoses, the pressure hose and a plurality of hose joints are formed in the inner side of a bottom plate of the tank; and a lifting handle is arranged on the outer side of the tank, and a pull rod and rollers are arranged at the bottom of the tank. According to the technical scheme, the portable reverse osmosis water filter device is simple in structure and reasonable in design, and has a wide applicable range to regions and water, drinking water can be obtained through purification by manpower, and the device is very suitable for being used by squads performing operation such as field work or earthquake relief work and the like.

Description

technical field [0001] The invention relates to a water quality filtering device, in particular to a portable reverse osmosis water quality filtering device. [0002] Background technique [0003] Due to human activities, natural disasters and other reasons, drinking water sources are polluted to varying degrees, which usually makes it difficult to guarantee the quality of drinking water for personnel working in the field, adventure tourism, and earthquake relief.

Problems solved by technology

[0003] Due to human activities, natural disasters and other reasons, drinking water sources are polluted to varying degrees, which usually makes it difficult to guarantee the quality of drinking water for field operations, adventure tourism, and earthquake relief personnel.

Existing drinking water purifiers usually use fiber filtration, activated carbon adsorption, ultraviolet disinfection and other treatment processes, which can effectively remove suspended solids, colloidal substances, bacteria and other pollutants in water, but have limited removal effect on organic pollutants and dissolved chemical substances , cannot completely eliminate the harm caused by water pollution

Resin purification, that is, ion exchange, has the ability to remove soluble chemical substances, but resin purification is a chemical purification method, and its water quality adaptability is poor. Changes in water quality will directly lead to a sharp shortening of the regeneration cycle, and a higher proportion of acid-base consumption, such as Carrying some harmful ions in the water can cause poisoning and failure of the ion exchange resin; the situation in the field and disaster areas is complicated, the water quality is various, and the composition and concentration of dissolved chemical substances in the water are difficult to distinguish. Therefore, field operations, especially earthquake relief In order to ensure the health of team members, it is not reliable to purify drinking water with resin

Reverse osmosis separation technology can effectively remove various soluble chemicals in drinking water, and the quality of the produced water is good, but it usually requires booster pumps, high-pressure pumps and other power equipment and power supply, which consumes a lot of power. Disaster relief in disaster areas, power supply is difficult to guarantee
