Embodiment approach

[0039] As an embodiment of the present invention, the "*" shaped cavity of the rotating wheel 41 is elastically connected with a gravity plate 5 through a spring column; Membrane 51; the rotating wheel 41 is located at the opening of the outlet pipe 45 with a first chute 52; the first chute 52 is located on the side of the elastic membrane 51 close to the reverse osmosis membrane 42; the first chute 52 slides A baffle 53 is connected; the opening of the outlet pipe 45 is located on the side of the first chute 52 away from the elastic membrane 51; the bottom of the filter chamber 4 communicates with the pumping chamber 21 through a conduit;

[0040] When working, by setting the gravity plate 5 and the elastic membrane 51, when the single inner cavity of the rotating wheel 41 faces upwards, under the action of gravity, the plunger structure formed by the gravity plate 5 and the spring column pulls the elastic membrane 51 downward to form an arc surface, And then make part of the...

Abstract

The invention belongs to the technical field of seawater purification, and particularly relates to a small integrated multi-plunger seawater desalination machine which comprises a shell, a water pumping mechanism and a desalination mechanism, wherein By arranging the water pumping device and the filtering device, in the reverse osmosis process, a reverse osmosis membrane is in a continuous rotating state, and in the rotating process, the reverse osmosis membrane is in contact with a sealing gasket and an isolation plate, so that the surface is preliminarily cleaned; meanwhile, in the rotating process, water flow in the reverse osmosis membrane is firstly subjected to reverse osmosis and flows into the rotating wheel, and along with rotation, when an opening of a single cavity of the rotating wheel faces downwards, fresh water which is not discharged in time permeates towards the outside of the reverse osmosis membrane under the action of gravity, so that impurities in the reverse osmosis membrane are effectively scoured. In cooperation with intermittent use of the reverse osmosis membrane, the service life of the reverse osmosis membrane can be effectively prolonged, and meanwhile, the reverse osmosis membrane is convenient to clean, so that the reverse osmosis membrane is prevented from being frequently cleaned in the seawater filtering process.

Description

technical field [0001] The invention belongs to the technical field of seawater purification, in particular to a small-scale integrated multi-plunger type seawater desalination machine. Background technique [0002] Seawater desalination machine is a mechanical device that uses seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure the stability of drinking water for coastal residents and water supply for industrial boilers. water supply. [0003] Most of the large-scale seawater desalination devices in the prior art rely on conventional energy sources, and require stable energy supply and long-term sites. For islands far away from the mainland that lack energy, ships with limited power supply, offshore platforms, maritime emergency rescue, field survival, and scientific investigations ...
