Hand-operated water purification unit with self power generation and automatic backwashing functions

Abstract

The invention relates to a hand-operated water purification unit with self power generation and automatic backwashing functions. A water production and backwashing system in the hand-operated water purification unit comprises a first solenoid valve which is arranged between a water production channel of a membrane module and a water inflow/outflow channel of a pressure tank, a second solenoid valve which is arranged on a concentrated water channel of the membrane module, a third solenoid valve which is arranged on the water production channel of the membrane module, and a fourth solenoid valve which is arranged on the water inflow/outflow channel of the pressure tank. The hand-operated water purification unit further comprises an electrical system. When backwashing time reaches a set value, the electrical system controls opening and closing of the first, second, third and fourth solenoid valves and allows all the high pressure water in the pressure tank to enter the membrane module via the water production channel of the membrane module and to flow out from a concentrated water outlet. When the hand-operated water purification unit reaches set backwashing time of an integrated circuit with timed opening and closing functions, backwashing of the membrane module is carried out. As main hand pump moves up and down, a hand generator in the electrical system is driven and generates electric energy; and the generated electric energy and electric energy generated by solar cell panels enter a storage battery so as to provide the water purification unit with electric energy.

Description

technical field [0001] The invention relates to water purification equipment in the field of water treatment, in particular to a manual water purification equipment with functions of self-generating and automatic backwashing. Background technique [0002] Membrane separation technology has been widely used in water treatment, and more and more types of water purification equipment have been developed based on the principle of membrane separation, so that people can drink clean and healthy water at any time. However, most of the current water purification equipment is aimed at areas with relatively concentrated population. It mostly uses electrification control, and realizes the operation and automatic control of the equipment by driving electric pumps, electric valves and other electrified equipment. Such equipment generally requires external 220V or 380V power supply. However, it cannot be used in some relatively remote places where the economy is underdeveloped, there is ...

AI Technical Summary

Problems solved by technology

Therefore, when this water purifier is in use, when a person is using the device normally, it will suddenly fail to produce water, and the rocker cannot be moved, making the device unusable

Even if the user cannot understand the characteristics of the device, forcibly pressing or lifting the rocker may cause equipment or personal damage, so automatic backwashing with controllable time cannot be realized
