Abstract
The invention discloses an anti-corrosion inner container of an electric water heater. The anti-corrosion inner container of the electric water heater comprises an inner container body of the electric water heater, an anode and a nut, wherein an outer thread connection base of the nut is connected with the inner container body of the electric water heater, the anode is connected with the middle of the inner container body of the electric water heater through the nut, the anode is a bar made of magnesium, and the anode and the outer thread connection base extend into the inner container body of the electric water heater to make contact with liquid in the inner container body of the electric water heater. The anti-corrosion control technology of the magnesium bar is adopted, the control electric potential is stable, and the anti-corrosion inner container can be used for devices which are corroded easily, for example, electric water heaters, solar electric water heaters and industrial boilers. The inner container and a heating tube can be respectively in an optimum protected state due to the anti-corrosion magnesium bar, and the anti-corrosion electric potential is stable.
Description
Technical field
The present invention relates to the electrochemical anti-corrosive technical field, relate in particular to a kind of anticorrosive inner bag of electric 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 cathodic protection.Cathodic 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 in other words more active metal of current potential is connected with protected metal; and be in the same electrolyte; making electronics on this metal transfer to protected metal gets on; whole protected metal is under negative, the identical current potential, namely forms galvanic cell by both.The protection metal replaces protected metal generation oxidation reaction, replaces the consumption that is corroded of protected metal.The electric heater of enamel inner container must install the magnesium rod additional.Because enamel inner container blackening last layer inanimate matter bristol glaze on the water heater steel plate special is made, non-corrosive, the market sale situation is pretty good.But the enamel inner container processing technology is had relatively high expectations, if technological level is inadequate, produces easily bubble or pinprick in the production process, and enamel fragility is larger simultaneously, and the vibrations in the transportation installation process, collision produce the quick-fried phenomenon of squama easily.In addition, enamel can dissolve gradually in hot water and peel off.More than these factors, all can cause the general steel plate under the enamel coating to expose, the impurity such as the carbon that general steel plate contains, sulphur are more, and the inner bag corrosion is leaked.
Summary of the invention
Hold corrosion-prone deficiency in order to overcome existing inner container of electric water heater, the invention provides a kind of anticorrosive inner bag of electric heater, can be used for electric heater, solar electric water heater, corrosive equipment.
The technical problem that the present invention requires to solve can be achieved through the following technical solutions:
A kind of anticorrosive inner bag of electric heater, comprise inner container of electric water heater, anode and nut, the external screw thread Connection Block of described nut connects inner container of electric water heater, anode links to each other with the inner container of electric water heater middle part by nut, anode and external screw thread Connection Block stretch into the inside of inner container of electric water heater, contact with liquid in the 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 with water heater liner and anodic bonding.
Described anode is installed in above the water heater liner, forms a kind of new anticorrosive inner bag structure, changes its processing dimension according to the large I of inner container of electric water heater.
Beneficial effect of the present invention is: adopted the anticorrosion control technology of magnesium rod, the control current potential is stable, can be used for the corrosive equipments such as electric heater, solar electric water heater, Industrial Boiler; Anticorrosion inner bag and the heating tube of making of magnesium rod is respectively at the best protection state, and anticorrosion current potential is stable.
Description of drawings
The present invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the connection diagram of the anticorrosive inner bag of electric heater of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose 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 present invention is described in further detail, a kind of anticorrosive inner bag of electric heater, comprise inner container of electric water heater 1, anode 2 and nut 3, the external screw thread Connection Block of described nut connects inner container of electric water heater 1, and inner container of electric water heater 1 middle part links to each other with anode 2 by nut 3, and anode is the barred body that magnesium is made, anode and external screw thread Connection Block stretch into the inside of inner container of electric water heater, contact with liquid in the inner container of electric water heater.Water heater liner is with magnesium rod aseptic technic, and available nut forms one with water heater liner and anodic bonding.Anode is installed in above the water heater liner, forms a kind of new anticorrosive inner bag structure, changes its processing dimension according to the large I of inner container of electric water heater.
During implementation, the magnesium rod claims again anode stub, and its Main Ingredients and Appearance is magnesium.In the water heater liner the inside, it contacts with water with inner bag (Main Ingredients and Appearance is iron) simultaneously, and forms galvanic cell.Because the water in the inner bag is not pure water, always contain various impurity and have certain corrosivity, when water temperature surpasses 40 ° of C, will produce incrustation scale.If there is not anodic magnesium rod, inner bag just is corroded.The anticorrosion employing sacrificial protection of magnesium rod; theoretical according to corrosion electrochemistry; behind plugged; just produce cathodic polarization behind the protected metallic structures Absorption Current; generally from stable natural potential (current potential when not adding protection) toward negative direction polarization 200～300mV or be defeated by-850mV(relative saturation calomel electrode; as follows), magnesium rod current potential just can get at 1100mv-1600mV can protect inner bag fully.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
