Example Embodiment

[0012] Specific implementation mode 1: the following combination figure 1 with figure 2 This embodiment will be described in detail. This embodiment consists of a hollow shaft 1, an upper bearing cover 2, an upper bearing 3-1, a lower bearing 3-2, an upper end cover 4, a stator part, a rotor part, a lower end cover 15, a lower bearing cover 16, a drain pan 17 and two The hollow shaft 1 is a shaft body whose upper end is communicated with the inner cavity and the lower end is closed;

[0013] The stator component is composed of a stator core 6-1, a number of permanent magnets 6-3, and a magnetic isolation sleeve 5. A number of permanent magnets 6-3 magnetized along the stator core 6-1 are distributed along the circumferential direction on the stator core 6-1. Thus, alternating magnetic poles of N and S are formed on the surface of the stator core 6-1; the stator part is fixed at the middle position of the length of the hollow shaft 1, and the stator core 6-1 is fixed on the oute...

Example Embodiment

[0018] Specific implementation manner 2: the following combination figure 1 This embodiment will be described in detail. The difference between this embodiment and the first embodiment is that a pulley 20 is fixed on the top end of the hollow shaft 1.

[0019] When external power (electrical energy, wind energy or other mechanical energy, etc.) drives the rotor component to rotate through the pulley 20, a rotating magnetic field is formed. The rotating magnetic field is interlinked with the stator component through the air gap, in addition to the hysteresis eddy current loss in the stator core 7-1 In addition, the resistance loss of the secondary short-circuit current generated by the induced electric potential in the cage-shaped conductive circuit, the surface loss and pulsation loss caused by the stator and rotor slotting caused by the air gap permeance harmonic magnetic field on the surface of the other iron core and the rotor current generation The loss caused by the leakage ...

Example Embodiment

[0022] Specific implementation manner three: the following combination figure 1 This embodiment will be specifically described. The difference between this embodiment and the first embodiment is that the shutter assembly further includes an extension rod 14-1, one end of the extension rod 14-1 is butted on the end of the adjusting screw 14, and the spring 13 is sleeved on the extension rod 14- 1 on the outer surface. This setting makes the work more stable and reliable.

Abstract

The invention relates to a seawater desalinator, in particular to a seawater desalination device which overcomes the defects of high energy consumption and low efficiency of the prior art and is used for desalinating seawater. The seawater desalination device comprises a hollow shaft, an upper bearing cover, an upper end bearing, a lower end bearing, an upper end cover, a stator part, a rotor part, a lower end cover, a lower bearing cover, a water-containing pan and two sealing sleeve assemblies. When the seawater desalination device is in work, seawater flows in the device from the hollow shaft and enters a cavity chamber with the stator part and the rotor part, external power drives the rotor part to rotate, the seawater is magnified by an electromagnetic reaction between the stator part and the rotor part and heated by generated heat, the rotating speed of the rotor part is increased after magnification is finished, a sealing pressure block is opened by utilizing centrifugal force which is generated by the high-speed rotation, the seawater enters a cavity of an outer cylinder body through a film and a film sealing sleeve, and fresh water flows in the water-containing pan. The invention changes the acting force between the solute and the solvent of an aqueous solution by a magnetic field, improves the flux of the film, increases the seawater temperature and enhances the water permeation capability.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to a seawater desalination device which combines magnetization treatment technology and membrane separation technology and integrates temperature, electromagnetic field, centrifugal force and membrane. Background technique [0002] One of the biggest problems facing the world in the 21st century is the water crisis. Although the total amount of water resources in my country is relatively large, the distribution is uneven, and the per capita resources are small. Some cities are often threatened by water shortages. Therefore, the development of new water resources and the control of water pollution have become a hot topic of concern. Among them, seawater desalination is an important way to obtain water for human life and production. Currently, seawater desalination methods mainly include membrane separation, electrodialysis, and distillation. Among them, the distillation method cons...
