A water distribution plate 10 is fixedly installed at the lower end of the water outlet tank 13. There is a water outlet 11 inside the water distribution plate 10. A water guide channel 9 is fixedly installed at the lower end of the water distribution plate 10. The right end of the primary filtration tank 1 is communicated with the left end of the impurity separation tank 2, with good filtration effect, and multi-stage filtration can be freely combined according to different usage situations;

[0027] A metal cage 15 is arranged at the inner end of the impurity separation tank 2. A water inlet 7 is fixedly installed at the right end of the impurity separation tank 2. A door panel 16 is fixedly installed at the upper end of the impurity separation tank 2. The impurity separation tank 2 is fixedly installed at the right end of the primary filtration tank 1, which is convenient for intercepting impurities and floating objects in seawater before the seawater enters the filtration process, and is convenient for opening the impurity separation tank 2 to take out the metal cage 15 for cleaning.

[0028] Specific working principle:

[0029] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, when using this freely combinable multi-stage seawater filter, connect the water inlet 7 to an external seawater delivery device. The seawater first enters the inside of the impurity separation tank 2. The metal cage 15 inside the impurity separation tank 2 intercepts larger impurities and floating objects in the seawater. Then the seawater enters the inside of the primary filtration tank 1. The primary filtration tank 1 performs the first-stage filtration on the seawater. As the seawater increases, the seawater flows upward and into the inside of the water guide channel 9. Then it flows into the inside of the water distribution plate 10 through the water guide channel 9, and upward through the water outlet 11 into the inside of the secondary filtration tank 4. Then, after being filtered by the secondary filtration tank 4 and the tertiary filtration tank 8, it surges into the inside of the water outlet tank 13. When the height of the seawater is higher than the height of the water outlet tank 13, the water flow passes through the metal mesh installed inside the water outlet tank 13. The seawater after being filtered by the tertiary solid impurities and suspended particles overflows outward through the water outlet tank 13 and flows into the inside of the water tank 12. Then it is pumped into the subsequent filtration and processing equipment through the water outlet pipe 14. The primary filtration tank 1, the secondary filtration tank 4, the tertiary filtration tank 8, and the water outlet tank 13 are installed and connected using the installation groove 3 and the snap ring 5. The sealing ring 6 plays a sealing role. The installation quantity and sequence of the primary filtration tank 1, the secondary filtration tank 4, the tertiary filtration tank 8, and the water outlet tank 13 can be adjusted according to different usage situations, which is flexible and convenient to use. After using it for a period of time, the impurities are isolated inside the metal cage 15. When cleaning the metal cage 15, open the door panel 16, take out the metal cage 15 or directly remove the impurities. The above completes a series of operations of this freely combinable multi-stage seawater filter. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.
