Description

technical field

[0001] The invention relates to the field of seawater desalination, in particular to a small flashlight-integrated multi-plunger type seawater desalination machine and a seawater desalination method. Background technique

[0002] At present, small water purification equipment is mainly divided into water purifiers and desalination machines; water purifiers are mostly made of ultrafiltration, microfiltration, low-pressure reverse osmosis, forward osmosis and other processes. Some toxic and harmful substances, but cannot desalinate seawater into drinkable fresh water by separating inorganic salts in water. Therefore, the preparation of seawater into potable freshwater can only be realized by seawater desalination machines, but most of the large-scale seawater desalination devices rely on conventional energy sources, which require stable energy supply and long-term sites. For islands far away from the mainland and lack of energy, the power supply is limited Lar...

Embodiment 1

[0060] In this embodiment, the water supply end 2 and the energy recovery end 3 are coaxially connected and arranged in parallel between the power end 1 and the filter end 4; specifically, the first pump shaft 2-31 and the second pump shaft 3- 31 is connected as a whole through the first coupling 5; a water supply gear box 9 is provided between the shell one 2-1 and the shell two 3-1; a second coupling is set between the water supply gear box 9 and the power end 1 6. A drive shaft 7 is provided inside the second coupling 6; one end of the drive shaft 7 is connected to the power end 1, and the other end is connected to the water supply gearbox 9;

[0061] Specifically, the power end 1 includes a motor 1-1, a speed reducer 1-2, a power gearbox 8 and a manual runner 1-3 connected in sequence; the manual runner 1-3 includes a wheel 1-31 and handle 1-32; said wheel disc 1-31 is provided with connecting hole 1-33 along the axial direction, and connecting hole 1-33 is provided with r...

Embodiment 2

[0076] In this embodiment, the power end 1, the water supply end 2 and the energy recovery end 3 are sequentially connected in the axial direction, and the filter end 4 is arranged in parallel on the side of the water supply end 2;

[0077] The first pump shaft 2-31 is axially connected to the second pump shaft 3-31 through a transmission block 1-7; preferably, the transmission block 1-7 is located between the concentrated water pressurization chamber 3-2 and The gear transmission group between the pressurized chambers; when the power end 1 provides power to drive the first pump shaft 2-31 to rotate, the second pump shaft 3-31 can rotate at a faster angular speed, thereby driving the second plunger 3-31 The reciprocating frequency of 32 is greater than that of the first plunger 2-32, and the pressurization effect on concentrated seawater is more obvious.

[0078] Preferably, the side of the first pump end cover close to the power end 1 is detachably connected with a motor connec...
