Abstract
The utility model relates to a sacrificial anode in a storage tank, which is applied to anticorrosion of a crude oil storage tank and a sewage tank. The sacrificial anode is cylindrical, an external thread is arranged at one end of the sacrificial anode; and a fixed disk is welded on the upper surface of a bottom plate of the storage tank, the fixed disk is in a cylindrical body, the center of the fixed disk is provided with a screw hole, and the sacrificial anode is fixed in the screw hole of the fixed disk. The sacrificial anode has the benefits that: the sacrificial anode plays a role of anticorrosion to the crude oil storage tank or the sewage tank, and the sacrificial anode is not easy to be buried by corrosion products in the tank, the sewage on the surface is easy to fall off, and protective current is diffused uniformly, thereby having the function of anticorrosion; moreover, the assembly of the sacrificial anode is simple and convenient, and the period of validity is long.
Description
Technical field
The utility model relates to crude oil storage tank and sewage jar aseptic technic field, particularly jar interior a kind of sacrificial anode.
Background technology
Crude oil storage tank or the anticorrosion needs of sewage jar are sacrificial anode fixedly, carries out anticorrosion with sacrificial anode.At present, crude oil storage tank or sewage jar rot-resistant sacrificial anode generally are to adopt the bar shaped sacrificial anode material, and directly are welded on the storage tank bottom plate.Because the height of bar shaped sacrificial anode is lower, corrosion product buries easily or sticks to the sacrificial anode surface, and it is limited to cause the protective current of sacrificial anode to arrive the height of storage tank shell, can not effectively protect a tank skin and a jar end.
The utility model content
The purpose of this utility model is: the sacrificial anode in a kind of storage tank is provided, can plays crude oil storage tank or sewage jar preservative activity, corrosion product comes off easily, and protective current is dispersed evenly, plays effective sacrificial anode preservative activity.
The technical solution adopted in the utility model is: the sacrificial anode in the storage tank, mainly form by shaft collar and sacrificial anode, and it is characterized in that: sacrificial anode is the cylinder bodily form, at an end of sacrificial anode outside screw is arranged; Face bonding is connected to shaft collar on storage tank bottom plate, and shaft collar is a column, and there is screw at the shaft collar center, at the screw internal fixing of shaft collar sacrificial anode is arranged.
Sacrificial anode adopts aluminum alloy materials to make, and diameter is between 50～150mm, and length is between 200～500mm.It highly is 80～150mm that shaft collar adopts plain carbon stool to make.
Described shaft collar is that cross section is orthohexagonal cylinder.The external circular diameter of regular hexagon is 150～300mm,
The beneficial effects of the utility model: the sacrificial anode in the utility model storage tank; can play crude oil storage tank or sewage jar preservative activity, and the in-tank corrosion product is not easy to bury sacrificial anode, surface contaminants comes off easily; protective current is dispersed evenly, plays the sacrificial anode preservative activity.In addition, the sacrificial anode simple installation, validity period is more permanent.
Description of drawings
Fig. 1 is the structural profile synoptic diagram after the sacrificial anode in the utility model storage tank is installed.
Fig. 2 is the synoptic diagram of the another kind of structure after the sacrificial anode in the storage tank is installed.
Among the figure, 1. storage tank bottom plate, 2. shaft collar, 3. sacrificial anode.
Embodiment
Embodiment 1: with the sacrificial anode in the storage tank is example, and the utility model is described in further detail.
Consult Fig. 1.Sacrificial anode in the utility model storage tank mainly is made up of shaft collar 2 and sacrificial anode 3.Sacrificial anode 3 adopts aluminum alloy materials to make the cylinder bodily form, and diameter is 100mm, and length is 300mm.The outside screw that M100 is arranged at an end of sacrificial anode 3.Face bonding is connected to shaft collar 2 on storage tank bottom plate 1, and shaft collar 2 is that cross section is orthohexagonal cylinder, and the regular hexagon circumscribed circle diameter is 300mm, highly is 100mm.There is the screw of M100 at shaft collar 2 centers, at the screw internal fixing of shaft collar 2 sacrificial anode 3 are arranged.
Embodiment 2: consult Fig. 2.Embodiment 2 with embodiment 1 difference is: the diameter of sacrificial anode 3 is 150 millimeters; Mill into the high regular hexagon cylinder of 50mm at the top of sacrificial anode 3.
Claims (3)
1. the sacrificial anode in the storage tank mainly is made up of shaft collar (2) and sacrificial anode (3), and it is characterized in that: sacrificial anode (3) is the cylinder bodily form, at an end of sacrificial anode (3) outside screw is arranged; Go up face bonding at storage tank bottom plate (1) and be connected to shaft collar (2), shaft collar (2) is a column, and there is screw at shaft collar (2) center, at the screw internal fixing of shaft collar (2) sacrificial anode (3) is arranged.
2. the sacrificial anode in the storage tank according to claim 1 is characterized in that: sacrificial anode (3) adopts aluminum alloy materials to make, and diameter is between 50～150mm, and length is between 200～500mm; Shaft collar (2) adopts plain carbon stool to make, and highly is 80～150mm.
3. the sacrificial anode in the storage tank according to claim 1 and 2, it is characterized in that: described shaft collar (2) is that cross section is orthohexagonal cylinder, and orthohexagonal circumscribed circle diameter is 150～300mm.
