Corrosion resistance of the tank body of the electrolytic tank is realized, and the service life of the electrolytic tank is prolonged.

Description

Corrosion resistant electrolyzer

Technical field

That the utility model belongs to is coloured, the electrolysis field of ferrous metal, is specifically related to the integrated poured electrolyzer of a kind of vinyl.

Background technology

The structure of electrolyzer comprises the cell body of electrolyzer and is arranged on outage on the cell body etc., during its electrolysis, electrodeposition, electricity that is widely used in metals such as gold and silver, nickel, cobalt, copper, iron, lead dissolves and produces.Be divided into three types of aqueous solution electrolytic cell, fusion electrolysis groove and nonaqueous solution electrolysis grooves according to the difference of electrolytic solution.

Traditional aqueous solution electrolytic cell trough body structure generally is that the cement skeleton adds glass reinforced plastic lining, promptly carries out the cement skeleton earlier, pastes glass reinforced plastic at cement tub inwall hand then and makees lining.The intensity of structural sheet is mainly by being embedded in the reinforcing bar in the cement.There is following defective in the electrolyzer cell body of said structure:

1) leak, major cause is that the bonding of frp lining layer and cement structures is bad, works long hours down, causes layering, disengaging; Air retaining wall separates with structural sheet, thereby has quickened the breakage of air retaining wall, in case corrosion resistant air retaining wall is damaged, electrolytic solution is understood the corrosion structure layer very soon, causes the seepage of electrolytic solution;

2) mechanical strength is low, and under the effect of the long-duration load of battery lead plate and high-temperature electrolyte, cement tub is easy to cracking;

3) high energy consumption, the heat insulation effect of cement tub is not good, keep electrolytic solution in certain temperature, need expend a lot of energy;

4) high maintenance costs because the electrolyzer of cement structures is easy to reveal and cracking, causes electrolytic solution to be revealed, and brings very big financial loss, thereby has also produced the maintenance cost of great number.

5) work-ing life short, cause the life-span of electrolyzer cell body low owing to reason such as leaking, mechanical strength is low.

In social development of today, the electrolysis industry begins to develop to high yield, less energy-consumption, high benefit, environmental protection direction, to electrolyzer product requirement large vol (13m ³More than), big supporting power, maintenance free, working life be long, and cell body exquisite, in light weight, lift easily and transport.And existing product is difficult to satisfy above-mentioned requirements.

Application number is that 200710070169.4 Chinese patent discloses the integrated poured electrolyzer of a kind of resin; It forms with Vinylite is integrated poured; It is shock-resistant, be not easy distortion, maintenance cost is low; But owing to there is not a special preservative coat, with the long-term contact process of acidity or alkaline electrolyte in, electrolyzer is corroded and reduction of service life easily.

The utility model content

The technical problem that the utility model will solve provides that a kind of cost is low, electrolyte resistance and the integrated poured electrolyzer of external environment corrosive vinyl.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of corrosion resistant electrolyzer; It comprises the cell body of electrolyzer and the said cell body of riser that is arranged on the said cell body is made up of the structural sheet and the external anti-corrosion layer of the impervious barrier that contacts with electrolytic solution, Vinylite cast; Said structural sheet is cast between impervious barrier and the external anti-corrosion layer, and said external anti-corrosion layer is made up of gel coating resin and FRP layer.

Said impervious barrier is cut carpet veneer by surperficial carpet veneer, the weak point that sticks to said surperficial carpet veneer outer wall and is sticked to said weak point and cuts the outer enhancement layer of carpet veneer and constitute.

Said impervious barrier thickness is 4 ~ 8mm, and the thickness of structural sheet is 60 ~ 85mm, and the thickness of external anti-corrosion layer is 4 ~ 6mm.

The thickness of said surperficial carpet veneer is 1 ~ 2.5mm, and the short thick 1 ~ 2mm of carpet veneer that cuts strengthens bed thickness 2 ~ 3mm.

At first on the internal mold of steel and external mold, make impervious barrier and external anti-corrosion layer respectively in the technique scheme, solidify; Assemble internal mold and external mold then, just the mixture of Vinylite, silica sand and solidifying agent is cast between internal mold and the external mold, curing, the demoulding.

The beneficial effect that adopts the utility model to produce is: impervious barrier of 1) setting up and external anti-corrosion layer can prevent effectively that electrolytic solution and extraneous acid or alkaline environment from infiltrating the inside of electrolyzer, cause the corrosion to electrolyzer, have prolonged the work-ing life of electrolyzer; 2) the utility model adopts trilaminar sandwich structure, has higher intensity, and the wall thickness of electrolyzer can be reduced to 70mm from present 120-150mm.

Embodiment

Referring to Fig. 1 and Fig. 2; Present embodiment comprises the cell body 1 of electrolyzer and is arranged on the riser 2 on the said cell body 1; Said cell body 1 is made up of the structural sheet 4 and the external anti-corrosion layer 5 of the impervious barrier that contacts with electrolytic solution 3, Vinylite cast; Said structural sheet 4 is cast between impervious barrier 3 and the external anti-corrosion layer 3, and said external anti-corrosion layer 5 is made up of gel coating resin and FRP (being commonly called as glass reinforced plastic) layer, and said gel coating resin contacts with structural sheet.

The surperficial carpet veneer of said impervious barrier 38, the weak point that sticks to said surperficial carpet veneer 8 outer walls are cut carpet veneer 7 and are sticked to said weak point and cut carpet veneer 7 outer enhancement layers 6 and constitute.

To sum up, the utility model adopts the sandwich structure of " sandwich ", and structural sheet 4 is cast between impervious barrier and the preservative coat, has not only improved the physical strength of cell body, and has improved the corrosion resistance nature of electrolyzer, has prolonged the work-ing life of electrolyzer.
