Self flushing system

Abstract

The invention provides a self flushing system including a PP cotton filter core connected with a water inlet; the PP cotton filter core is connected to a granular activated carbon filter core; water passes through the granular activated carbon filter core and then flows into a compressed activated carbon filter core; the compressed activated carbon filter core communicates with an RO reverse osmosis membrane, and water through the RO reverse osmosis membrane is divided into two parts of filtered water and sewage, wherein the filtered water is connected to a rear-mounted activated carbon filter core and then flows to a water outlet, and the sewage is connected to a drainage ditch; a first electromagnetic valve is arranged between a water inlet and the PP cotton filter core; the water inlet and the RO reverse osmosis membrane are connected by a flushing pipeline, a flushing electromagnetic valve is arranged for flushing control of the RO reverse osmosis membrane. The water inlet and the RO reverse osmosis membrane are connected by the flushing pipeline, so the membrane can be flushed at any time, and the service life of the membrane is prolonged; arrangement of an original high-pressure pump is canceled, and the water source purification treatment is achieved by the water flow pressure of a water purifier, so the water purifier has no noise, the power consumption is saved and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of drinking water treatment, in particular to a self-flushing system. Background technique [0002] Due to the pollution of tap water pipes and the leakage of the pipe network, there are pollutants such as sediment, rust and microorganisms in the water. In order to ensure the provision of high-quality drinking water, water purifiers have emerged as the times require. [0003] In order to increase the pressure of the water, the traditional water purifier generally has a high-pressure pump. The high-pressure pump consumes a lot of power and is noisy. The traditional water purifier does not have a system for flushing the membrane, and the service life of the membrane is very short. Therefore, how to solve the noise of the high-pressure pump and prolong the service life of the membrane is an urgent problem to be solved at present. Contents of the invention [0004] The problem to be solved by the present inve...
