Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
As depicted in figs. 1 and 2, the embodiment of the present invention proposes a kind of anti-corrosion filter unit peculiar to vessel, including feed pathway 1, outer
Housing 2 and liquid outlet channel 3, the feed pathway 1 and the liquid outlet channel 3 are arranged in the side wall of shell body 2, the shell
The cavity 6 of the feed pathway 1 and the liquid outlet channel 3 is communicated with inside body 2, is removably provided with the cavity 6
Filter core 5, in order to ensure filter effect, filter core 5 can be changed with disassembly, cleaning or directly.Specifically, the shell body 2 is hollow
It is cylindric, and the cavity 6 and the extraneous second opening are communicated with the shell body 2 and is opened for covering described second
The closure 4 of mouth, closure 4 makes its sealing with some screw locks in the second opening, when safeguarding, it is only necessary to open closure 4
It can be changed or the work such as inspection part.Transparent work form is also provided with the side wall of shell body 2, through work
Make form, the working condition of the device can be observed.In addition, the feed pathway 1 and the liquid outlet channel 3 are arranged on outside described
In the side wall of housing 2, the feed pathway 1 and the liquid outlet channel 3 are arranged on shell body 2 in intermediate symmetry, it is of course also possible to
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 pathway
1 and the liquid outlet channel 3 be provided with connection marine pipeline bump joint.
Further, the shell body 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 block, and first metalwork 7 can set one or more, first metal
Part 7, which is connected through a screw thread, welds or riveted, to be fixed on the closure 4.In the present embodiment, first metalwork 7 is preferred
Connected mode is threaded connection, is easy to subsequently change.The filter core 5 and the shell body 2 are made up 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 is zinc or magnesium, the negative electrode material
Expect for spheroidal graphite cast-iron, carbon steel, chrome-molybdenum steel, stainless steel or copper.Structure between first metalwork 7, shell body 2 and the seawater of severe corrosive
Into galvanic cell, the first stronger metalwork 7 of reproducibility will occur oxidation reaction as the seawater of negative pole and severe corrosive and consume,
So as to protect the shell body 2 as anode not corroded.In addition, the inside of the first metalwork 7 is provided with accommodating chamber 9, and institute
State the sealing-plug that the accommodating chamber 9 and the extraneous first opening are communicated with the first metalwork 7 and covers first opening
10, in the present embodiment, sealing-plug 10 is rubber stopper.The consumptive material of gas, tool can be produced in the accommodating chamber 9 filled with chance seawater
Body, the consumptive material is preferably sodium bicarbonate particle, naturally it is also possible to is the material that other can produce gas with seawater, such as sodium
Deng, when the first metal, 7 is consumed to a certain extent, there is the accommodating chamber 9 that the seawater of severe corrosive enters in the first metalwork 7,
And chemical reaction generation gas occurs with the sodium acid carbonate of intracavitary, caused gas forms high pressure in confined space, will sealed
The ejection of plug 10, so as to play a part of reminding the first metalwork of staff 7 to consume to a certain extent and need to change, need
It is noted that sounding whistle can be set in the accommodating chamber 9 at the sealing-plug 10, when gas sprays and ejects
While sealing-plug 10, gas sends sound by sounding whistle, can further remind staff to change the first metalwork
7。
Further, the second metalwork 8 made of the anode material is removably installed on the filter core 5.
Including filter paper, the filter paper is surrounded in the filter core 5 and second metalwork 8 be enclosed in by tubular, similarly, the second metalwork
8th, form galvanic cell between filter core 5 and the seawater of severe corrosive, the second stronger metalwork 8 of reproducibility will be used as negative pole with it is strong
Corrosive seawater occurs oxidation reaction and consumed, and so as to protect the filter core 5 as anode, it is not corroded.Described
Two metalworks 8 are ring-type or bulk, and second metalwork 8 is fixedly connected on outside the filter core 5, fixed second gold medal
When belonging to part 8, described second metal, 8 bundled fixeds can be existed through the filter opening of filter core 5 with Plastic Bandage or plastic card sets
On the filter core 5, the filter core 5 for being connected with second metalwork 8 is then surrounded into covering along outer wall together with the filter paper again.
During work, seawater first filters a part of impurity through filter paper, then by the 8 progress chemical preservations of the second metal, filter core 5 is realized double
Protect again.In addition, appropriate spelter etc. can also be set in the feed pathway 1 described in the present embodiment and the inwall of liquid outlet channel 3
Relatively active metal, further protect feed pathway 1 and liquid outlet channel 3 made of iron, steel or copper etc..
Compared with it is preferred that the anti-corrosion filter preferred size peculiar to vessel setting of the present embodiment is as follows：A diameter of 500mm of shell body 2
~600mm, its height are 360mm~450mm.When the second metalwork 8 is block, its a length of 30mm~50mm, a width of 10mm
~20mm, a height of 320mm, when the second metalwork 8 for it is circular when, its ring-type internal diameter be 400mm, external diameter for 420mm~
440mm, a height of 30mm~50mm.It should be noted that filter core 5 can be cylindric, its height could be arranged to it is described outer
The cavity 6 of housing 2 it is highly consistent, i.e., when closure 4 covers, the top of filter core 5 props up closure 4, and the bottom of filter core 5 props up sky
The bottom of chamber 6.When the present invention is arranged to dimensions above, suitable for ship pipeline, an appropriate filtering can be reached
And installation effect.
In summary, the present invention, using the cathode protection method of sacrificial anode, is set while filtering sea function is realized
As anode and replaceable second metalwork 8 and first metalwork 7, and by the shell body 2 and the filter core 5
It is arranged to suitable cathode material, greatly enhances the antiseptic property of itself, in addition, the present invention utilizes the seawater of severe corrosive
Reacted with sodium acid carbonate and produce the principle of gas, it is strong rotten when the first metalwork 7 as anode consumes to a certain extent
The seawater of corrosion flows into the accommodating chamber 9 and sodium acid carbonate reacts and produces gas, high pressure is formed, by the bullet of sealing-plug 10
Open, so as to reach the reminding effect for changing the first metalwork 7, be easy to regular maintenance.
