Abstract
The utility model discloses a sacrificial anode device for controlling corrosion in a storage tank, which is designed for avoiding corrosion caused by welding of the sacrificial anode and ensuring the anti-corrosion effect, namely, the sacrificial anode fixed on a bottom plate of the storage tank is provided with a horizontal central through hole; the sleeve arranged at the two sides of the sacrificial anode is provided with a horizontal central screw hole; the screw B penetrates through the center through hole of the sacrificial anode, the two ends of the screw B extend out of the sacrificial anode, and the screw B is connected in the center screw hole of the sleeve in a threaded manner; the other end of the central screw hole of the sleeve is in threaded connection with a screw A, and the other end of the screw A is connected with the wall of the storage tank in a supporting way. The sacrificial anode of the utility model adopts the fixing device and the storage tank which are connected into a whole, thus preventing the corrosion caused by welding and well protecting the crude oil storage tank. The utility model has simple structure, convenient installation, firm anode fixation, easy replacement and long service life.
Description
Technical field
The utility model relates to a kind of storage tank internal corrosion control and uses sacrificial anode device, belongs to crude oil storage tank aseptic technic field.
Background technology
In present oil field product was built, it is anticorrosion that crude oil storage tank and steel water pot use sacrificial anode to carry out, and is about to the bar shaped sacrificial anode material and directly is welded on the storage tank bottom plate.Because weld easily produces stress and galvanic corrosion, so can reduce the preservative effect of sacrificial anode, can not effectively protect storage tank bottom.
Summary of the invention
The purpose of this utility model is to provide a kind of storage tank internal corrosion control sacrificial anode device, and it can solve the corrosion that causes because of the sacrificial anode welding, and its preservative activity is effectively guaranteed.
Concrete technical scheme of the present utility model is as follows:
Be fixed on the central through hole that sacrificial anode on the storage tank bottom plate is provided with level.The sleeve that is located at the sacrificial anode both sides is provided with the center screw of level.Screw rod B is through in the sacrificial anode central through hole, and sacrificial anode is stretched out at its two ends, is threadedly connected in the sleeve center screw.The sleeve center screw the other end screw rod A that is threaded, screw rod A the other end support and connection storage tank shell.
Sacrificial anode of the present utility model adopts stationary installation and storage tank to be connected as a single entity, and can prevent the corrosion that causes because of welding, thereby can protect well crude oil storage tank.The utility model is simple in structure, and is easy for installation, and long service life is changed easily in the anode fixation.
Description of drawings
Fig. 1 is storage tank internal corrosion control sacrificial anode device structural representation.
Embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
Storage tank internal corrosion control is comprised of screw rod A3, screw shell 4, screw rod B5 and sacrificial anode 6 with sacrificial anode device:
Be fixed on sacrificial anode 6 on the storage tank bottom plate 1, cuboid and be provided with level and circular central through hole.The sleeve 4 that is located at sacrificial anode 6 both sides is provided with the center screw of level.Screw rod B5 is through in sacrificial anode 6 central through holes, and sacrificial anode 6 is stretched out at its two ends, is threadedly connected in sleeve 4 center screws.The sleeve 4 center screw the other ends screw rod A3 that is threaded, screw rod A3 the other end support and connection storage tank shell 2.Sacrificial anode 6 adopts aluminum alloy materials to make, and sleeve 4, screw rod A3 and screw rod B5 adopt plain carbon stool to make.
