Abstract
The utility model discloses an impressed current cathodic protection device for an inner container of a water heater, and is characterized in that the protection device consists of an electronic anode and a controller, wherein a metal or metal oxide layer which is electrically-conductive and insoluble is plated on the surface of the electronic anode; the electronic anode is coated with an insoluble, anticorrosive and insulating engineering plastic supporting strip; the positive electrode of the controller is connected with the electronic anode; and the negative electrode of the controller is connected with the inner container of the water heater. The impressed current cathodic protection device for the inner container of the water heater has the advantages of long service life, no maintenance, no pollution, low cost and convenience for use.
Description
Technical field
The utility model relates to a kind of anti-corrosion protection device, relates in particular to a kind of etch-proof impressed current catholic protection device of water heater liner that can be used for.
Background technology
Because the water heater liner etching problem is serious, the producer that great majority are produced water heater liner all adopts the magnesium rod to control the inner bag etching problem, has following shortcoming: the current potential of magnesium rod is negative excessively, is easy to generate overprotection; The spending rate of magnesium rod is very fast, and the protection against corrosion life-span is short, needs frequent change, and after cost is high; Magnesium rod degradation production in water is a magnesiumcarbonate, forms flocks jointly with lime carbonate, influences water quality; Interpolation element aluminum in the magnesium rod, its degradation production are the principal elements that causes senile dementia.Therefore to the protection problem of water heater liner cleanliness without any pollution just pendulum we in face of.
Summary of the invention
The utility model provides a kind of impressed current catholic protection device of water heater liner, and this device carries out anti-corrosion protection through impressed current to water heater liner.
The utility model solves the technical scheme that its technical problem adopted: protector is made up of electronics anode and unit.The electronics anode surface is coated with that one deck can conduct electricity but the metal or the MOX of indissoluble.The electronics anode be wrapped with do not dissolve, anticorrosive, insulating engineering plastics support bar.The positive pole of unit is connected with the electronics anode, and negative pole is connected with water heater liner.
The beneficial effect of the utility model is, the life-span is long, non-maintaining, pollution-free, cost is low, easy to use.
Description of drawings
Accompanying drawing is the one-piece construction synoptic diagram.
Embodiment
The utility model comprises electronics anode 1, support bar 2, fastening piece 3, unit 4.Shown in accompanying drawing, described electronics anode 1 surface is coated with that one deck can conduct electricity but the metal or the MOX of indissoluble.Electronics anode 1 be wrapped with do not dissolve, anticorrosive, insulating engineering plastics support bar 2.During use, electronics anode 1 and support bar 2 are passed water-heater housing 5, and fixing by fastening piece 3.The positive pole of unit 4 is connected with electronics anode 1, and negative pole is connected with water-heater housing 5.
