It states on 2 side wall of outer housing, the feed pathway 1 and the liquid outlet channel 3 are arranged in intermediate symmetry on outer housing 2, certainly,
It can make feed pathway 1 as needed and liquid outlet channel 3 is L-shaped or other angles are set, in order to easy to connect, the feed liquor
Channel 1 and the liquid outlet channel 3 are both provided with the bump joint of connection marine pipeline.
Further, the outer housing 2 is connected with the first metalwork 7 made of anode material, institute in the cavity 6
Stating the first metalwork 7 can be bar-like or blocky, and first metalwork 7 can set one or more, first metal
Part 7, which is connected through a screw thread, welds or rivets, to be fixed on the sealing cover 4.In the present embodiment, first metalwork 7 is preferred
Connection mode is is threadedly coupled, convenient for subsequently replacing.The filter core 5 and the outer housing 2 are made of cathode material, the anode
Material is stronger than the movable metallic of the cathode material.The preferably described anode material of the present embodiment be zinc or magnesium, the cathode material
Expect for spheroidal graphite cast-iron, carbon steel, chrome-molybdenum steel, stainless steel or copper.Structure between first metalwork 7, outer housing 2 and the seawater of strong corrosive
Into primary battery, stronger first metalwork 7 of reproducibility will occur oxidation reaction as the seawater of cathode and strong corrosive and consume,
So as to which the outer housing 2 as anode be protected not corroded.In addition, first metalwork 7 is internally provided with accommodating chamber 9, and institute
It states the first metalwork 7 and is equipped with the sealing-plug for connecting the accommodating chamber 9 and the extraneous first opening and covering first opening
10, in the present embodiment, sealing-plug 10 is rubber stopper.The consumptive material of gas, tool can be generated in the accommodating chamber 9 filled with chance seawater
Body, the consumptive material is preferably sodium bicarbonate particle, naturally it is also possible to be the substance that other can generate gas with seawater, such as sodium
Deng, when the first metal, 7 is consumed to a certain extent, the seawater with strong corrosive enters the accommodating chamber 9 in the first metalwork 7,
And chemical reaction generation gas occurs with the sodium bicarbonate of intracavitary, the gas of generation forms high pressure in confined space, will seal
10 pop-up of plug so as to play the role of that the first metalwork of staff 7 is reminded to consume to a certain extent and need replacing, needs
It is noted that sounding whistle can be set in the accommodating chamber 9 at the sealing-plug 10, when gas sprays and pops up
While sealing-plug 10, gas makes a sound by sounding whistle, and staff can further be reminded to replace the first metalwork
