Abstract
The utility model discloses an anti-corrosive inner container of an electric water heater. The anti-corrosive inner container comprises an electric water heater inner container, an anode and a nut, wherein an external thread connecting seat of the nut is connected with the electric water heater inner container, the anode is connected with the middle part of the electric water heater inner container through the nut, the anode is a rod body made from magnesium, the anode and the external thread connecting seat extend inside the electric water heater inner container to be contacted with a liquid in the electric water heater inner container. The anti-corrosive inner container can stably control potentials by adopting a magnesium rod anti-corrosion control technology, and can be used for easily-corroded equipment such as an electric water heater, a solar electric water heater, an industrial boiler and the like; the inner container and a heating pipe are respectively in the best protection state due to anti-corrosion of the magnesium rod, and the anti-corrosion potentials are stable.
Description
Technical field
The utility model relates to electrochemical anti-corrosive technical field, relates in particular to a kind of anticorrosive inner bag of electric water heater.
Background technology
Anticorrosion this project of inner container of electric water heater belongs to electrochemistry category scope, and its theoretical source is the principle from galvanic protection.Galvanic protection; it is an electrochemistry technical term; the popular saying of magnesium rod protection is that sacrificial protection-galvanic anode protection is that the more negative more active metal in other words of current potential is connected with protected metal; and in same ionogen; transfer transport on this metal is gone to protected metal; make whole protected metal under negative, an identical current potential, namely by both, form galvanic cell.Protection metal replaces protected metal generation oxidizing reaction, replaces the consumption that is corroded of protected metal.The electric water heater of enamel inner container must install magnesium rod additional.Because enamel inner container blackening last layer inanimate matter bristol glaze on water-heater steel plate special is made, non-corrosive, market sale situation is pretty good.But enamel inner container complete processing is had relatively high expectations, if state of the art is inadequate, in production process, easily produce bubble or pinprick, enamel fragility is larger simultaneously, and the vibrations in transportation installation process, collision easily produce fish-scaling effect.In addition, enamel can dissolve and peel off gradually in hot water.These factors, all can cause the general steel plate under enamel coating to expose above, and the impurity such as the carbon that general steel plate contains, sulphur are more, easily make inner bag corrosion leak.
Utility model content
In order to overcome existing inner container of electric water heater, hold corrosion-prone deficiency, the utility model provides a kind of anticorrosive inner bag of electric water heater, can be used for electric water heater, solar electric water heater, corrosive equipment.
The utility model requires the technical problem solving to be achieved through the following technical solutions:
A kind of anticorrosive inner bag of electric water heater, comprise inner container of electric water heater, anode and nut, the outside screw Connection Block of described nut connects inner container of electric water heater, anode is connected with inner container of electric water heater middle part by nut, anode and outside screw Connection Block stretch into the inside of inner container of electric water heater, contact with the liquid in inner container of electric water heater.
Described anode is the barred body that magnesium is made.
Described water heater liner is with magnesium rod aseptic technic, and available nut forms one by water heater liner and anodic bonding.
Described anode is arranged on above water heater liner, forms a kind of new anticorrosive inner bag structure, according to the large I of inner container of electric water heater, changes its finish size.
The utility model beneficial effect is: adopted the anticorrosion control techniques of magnesium rod, controlled current potential stable, can be used for the corrosive equipments such as electric water heater, solar electric water heater, Industrial Boiler; Anticorrosion inner bag and the heating tube of making of magnesium rod is respectively at best protection state, and anticorrosion current potential is stable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is the connection diagram of the anticorrosive inner bag of the utility model electric water heater.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Below in conjunction with Fig. 1, the utility model is described in further detail, a kind of anticorrosive inner bag of electric water heater, comprise inner container of electric water heater 1, anode 2 and nut 3, the outside screw Connection Block of described nut connects inner container of electric water heater 1, and inner container of electric water heater 1 middle part is connected with anode 2 by nut 3, and anode is the barred body that magnesium is made, anode and outside screw Connection Block stretch into the inside of inner container of electric water heater, contact with the liquid in inner container of electric water heater.Water heater liner is with magnesium rod aseptic technic, and available nut forms one by water heater liner and anodic bonding.Anode is arranged on above water heater liner, forms a kind of new anticorrosive inner bag structure, according to the large I of inner container of electric water heater, changes its finish size.
During concrete enforcement, magnesium rod claims again anode bar, and its major ingredient is magnesium.In water heater liner the inside, it contacts with water with inner bag (major ingredient is iron) simultaneously, and forms galvanic cell.Because the water in inner bag is not pure water, always contain various impurity and there is certain corrodibility, when water temperature surpasses 40 ° of C, will produce incrustation scale.If there is no anodic magnesium rod, inner bag is just corroded.The anticorrosion employing sacrificial protection of magnesium rod; theoretical according to corrosion electrochemistry; after switching on power; after protected metallic structures absorption current, just produce cathodic polarization; generally from stable spontaneous potential (current potential while not adding protection) toward negative direction polarization 200～300mV or be defeated by-850mV(relative saturation mercurous chloride electrode; as follows), magnesium rod current potential just can obtain and can protect fully inner bag at 1100mv-1600mV.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
