Dynamic lid is connected by conducting wire with tank body.
The operation principle of the present invention is as follows：Using the stronger sacrificial anode material block of reproducibility as protection pole, with being protected
Tank body be connected form primary battery, the stronger sacrificial anode material block of reproducibility will be used as cathode generation oxidation reaction and consume,
Protected tank body can be safe during anti-corrosion protection so as to fulfill the antisepsis of tank body to avoid corrosion as anode
Property is good.
In a kind of antisepsis protector of above-mentioned floating roof petroleum storage tank, the sacrificial anode material block is slidably connected at
On the elastic helix body.It, can be as desired by between each anode material block of adjusting by using the mode being slidably connected
Spacing, control its position on elastic helix body.
In a kind of antisepsis protector of above-mentioned floating roof petroleum storage tank, the sacrificial anode material block is set at equal intervals
It puts on the elastic helix body.So sacrificial anode material block is evenly distributed compared with tank wall, so that protective current
Uniformly, protecting effect is good.
In a kind of antisepsis protector of above-mentioned floating roof petroleum storage tank, the elastic helix body is in hollow tubular, institute
It states and a controller is equipped in elastic helix body and several are connected with controller and uniformly set along elastic helix body length direction
The electromagnet put, the sacrificial anode material block are equipped with iron block.It so can be by controlling the break-make of the electromagnet on tube body
Electricity controls the position of anode material block, in order to preferably controlling as needed the position of anode material block.
In a kind of antisepsis protector of above-mentioned floating roof petroleum storage tank, insulating layer is coated on the outside of the iron block.It is logical
Crossing cladding insulation sides prevents iron block from being contacted with the external world, and the impurity such as iron filings is avoided to be mixed into oil tank.
In a kind of antisepsis protector of above-mentioned floating roof petroleum storage tank, the sacrificial anode material block is magnesium, magnesium closes
One kind in golden, pure zinc, kirsite or aluminium alloy.
Compared with prior art, advantages of the present invention is as follows：
1st, it is not required external power supply, therefore be capable of safety plays antisepsis；
2nd, failure rate is few, safeguards that probability is small；
3rd, easily installation and maintenance, it is convenient that sacrificial anode material block is replaced, as long as elastic helix body is taken out i.e. replaceable；
4th, sacrificial anode material block is uniformly distributed, and is capable of providing uniform electric current distribution, and anti-corrosion effect is more preferable.
