Abstract
The utility model relates to an external current cathode protector for an inner wall of a steel water tank, which is composed of noble metal oxidizing anodes, a reference electrode, a current distributing box, a potentiostat and a matching block. The utility model is characterized in that different noble metal oxidizing anodes are connected in series by cables and form anode strings, a plurality of the anode strings are then hoisted into the steel water tank from the top of the tank, the matching block is hung at lower end of the tank, the reference electrode is installed at the proper position matched with the anode strings at the lower part of the tank top where the current distributing box is arranged, the cables of the anode strings and the cables of the reference electrode are respectively centralized and combined through the current distributing box and then respectively connected to the corresponding connection points of the potentiostat, and the potentiostat has the function of automatically adjusting electric potential. The utility model can automatically adjust the protection current which is required in protecting an inner wall steel plate of the tank according to the water level and the variation of media in the water tank, and the ideal effect of corrosion prevention for cathodic protection is achieved.
Description
One, technical field
The utility model relates to a kind of tank galvanic protection aseptic technic, specifically a kind of steel water tank inwall impressed current catholic protection device.
Two, background technology
The steel water tank; especially seawater storage tank and sewage storage tank; etching problem is quite serious; in the past steel water tank inwall was not generally adopted galvanic protection or adopted galvanic anode protection; but the galvanic anode protection method has following defective: (1) need connect a large amount of anode blocks at a tank skin and a jar back welding, and installation and welding job amount are big.(2) the especially influence of anode weight and difficulty of construction, protection mainly concentrates on the pot bottom branch, and is very limited to the protection of tank skin.(3) life, generally about 5-8, then anode just needed to change, and cost performance is not high.(4) the anode welding can exert an influence to the intensity and the weld seam of tank body.(5) product that produces behind the anode consumption influences water quality.
Three, summary of the invention
The purpose of this utility model provides a kind of steel water tank inwall impressed current catholic protection device, solves the existing problem of above-mentioned prior art.
The utility model is by precious metal oxidation anode, reference electrode, divide electronic box, potentiostat, balancing weight is formed, it is characterized in that different noble metallic oxide anodes is connected in series with cable, constitute anodic column string, with many anodic column string, hang in the steel water pot by tank deck, its lower end hangs with balancing weight, reference electrode is installed in tank deck below and the suitable correct position that mates of anodic column string, divide electronic box to be arranged on tank deck, the anodic column string cable, the reference electrode cable gathers merging separately by minute electronic box, receives the corresponding contact of potentiostat separately, and potentiostat self is provided with automatic adjusting current potential function.This device can be protected needed protective current according to the height of tank inside water level and the automatic regulating tank inwall of the variation steel plate of inner splendid attire medium, reaches the preservative effect of ideal galvanic protection.
Precious metal oxidation anode is a tubulose or bar-shaped.
Compared with the prior art the utility model has the following advantages:
1, protection potential is even, and protective current output is adjustable, favorable anti-corrosion effect.
2, easy for installation, installation rate is fast, and is time saving and energy saving, the cost performance height, and cathode protection technology is reliable, long service life.

Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of precious metal oxidation anode 3, balancing weight 4, reference electrode 5, tapping box 6 and potentiostat 7, different precious metal oxidation anodes are connected in series with cable, constitute anodic column string, determine that according to water quality with what burning anode anode is made into tubulose or bar-shaped.Hang on balancing weight in the anodic column string bottom, preferably use the concrete weight coating piece, anodic column string seals in the set hole of tank deck, and the upper end insulated enclosure is fixed, and anodic column string is parallel with tank skin.Reference electrode is installed in the tank deck bottom of water tank 2 and the position that anodic column string is fit to coupling; anodic column string cable and reference electrode cable are aggregated into tapping box separately and merge; draw separately on the corresponding contact of receiving potentiostat; cathode cable and zero-bit cable are also received on the corresponding contact of potentiostat, form the galvanic protection loop.
Claims (2)
1; a kind of steel water tank inwall impressed current catholic protection device; by precious metal oxidation anode; reference electrode; divide electronic box; potentiostat; balancing weight is formed; it is characterized in that different noble metallic oxide anodes is connected in series with cable; constitute anodic column string; with many anodic column string; hang in the steel water pot by tank deck; its lower end hangs with balancing weight; reference electrode is installed in tank deck below and the suitable correct position that mates of anodic column string; divide electronic box to be arranged on tank deck; the anodic column string cable, the reference electrode cable gathers merging separately by minute electronic box, receives the corresponding contact of potentiostat separately.
2, steel water tank inwall impressed current catholic protection device according to claim 1 is characterized in that described precious metal oxidation anode is a tubulose or bar-shaped.
