Abstract
The utility model discloses seawater container corrosion preventing equipment comprising a plug screw (1), a threaded seat (3), an alloy anode (4) and a seawater container body (5), wherein the threaded seat (3) is welded on the seawater container body (5); a boss (6) of which the diameter is equal to that of the threaded seat (3) is formed at the bottom of the plug screw (1), the boss (6) is hollow, threads matched with the threaded seat (3) are turned on four sides of the boss (6), the plug screw (1) is in threaded connection with the threaded seat (3) through the threads on the four sides of the boss (6), the upper end of the alloy anode (4) is fixed at the hollow part of the boss (6), and the bottom of the alloy anode (4) passes through the threaded seat (3) and stretches into the seawater container body (5). According to the seawater container corrosion preventing equipment disclosed by the utility model, the alloy anode is arranged at a position which is soaked into seawater for a long term on the wall of a container, and the active alloy anode serving as the cathode of a primary battery is corroded, so that the seawater container can be protected from being electrochemically corroded, whereas the alloy anode is corroded.
Description
Technical field
The utility model relates to one and prevents sea container etching apparatus.
Background technology
When metal is placed in electrolyte solution, steel surface can form a kind of microbattery, also claims corrosion cell.Conventionally, sea container is mainly taking the steel plate of irony as main, and the seawater of wherein containing is equivalent to electrolyte solution, because steel plate is always impure, be actually alloy, outside deironing, also contain graphite, cementite and other metal and impurity, their great majority do not have ironwork to sprinkle; The anode of corrosion cell forming is like this iron, and negative electrode is impurity, again due to iron and impurity close contact, corrosion is constantly carried out, and gently causes for a long time internal tank rugged in the past, the heavy container seepage of boring a hole.
Summary of the invention
In order to address the above problem; the utility model provides one to prevent sea container etching apparatus; position on wall of container in long period of soaking seawater arranges the alloy anode more active than ferro element; active alloy anode is corroded as the negative pole of galvanic cell; can protect sea container not to be subject to galvanic corrosion, and corrosion removal alloy anode.
The utility model has adopted following technical scheme: one prevents sea container etching apparatus, comprise plug screw, threaded block, alloy anode and sea container body, described threaded block is welded on sea container body, in threaded block, be provided with screw thread, described sea container body and threaded block corresponding position are provided with opening; Described plug screw bottom is and the isodiametric boss of threaded block, described boss is hollow form, the surrounding car of boss is shaped with the screw thread mating with threaded block, described plug screw is threaded with threaded block by the screw thread of boss surrounding, the upper end of described alloy anode is fixed on the hollow part of boss, and bottom is stretched in sea container body 5 by the opening on sea container body 5 through threaded block 3.
Between described plug screw and threaded block, be provided with gasket, plug screw screws in threaded block through gasket.
The utlity model has following beneficial effect: the utility model has been stopped the micro-cell corrosion of sea container effectively, extended the work-ing life of sea container; Meanwhile, the utility model is simple in structure, with low cost, and changes conveniently, can carry out multiple spot setting according to the size of sea container, between plug screw and threaded block, is provided with gasket, guarantees both watertights.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is that one prevents sea container etching apparatus, comprise plug screw 1, threaded block 3, alloy anode 4 and sea container body 5, described threaded block 3 is welded on sea container body 5, in threaded block 3, be provided with screw thread, described sea container body 5 is provided with opening with threaded block 3 corresponding positions; Described plug screw 1 bottom is and the isodiametric boss 6 of threaded block 3, described boss 6 is hollow form, the surrounding car of boss 6 is shaped with the screw thread mating with threaded block 3, described plug screw 1 is threaded with threaded block 3 by the screw thread of boss 6 surroundings, the upper end of described alloy anode 4 is fixed on the hollow part of boss 6, and bottom is stretched in sea container body 5 by the opening on sea container body 5 after threaded block 3; Between described plug screw 1 top and boss 6, be provided with flats projection, between plug screw 1 and threaded block 3, be provided with gasket 2, gasket 2 is placed between the bottom and threaded block 3 of plug screw 1 flats projection, and plug screw 1 screws in threaded block 3 through gasket 2.
