Description
Technical field
Pretreating device in continuous galvanizing line is the utility model is related to, especially a kind of zinc-plated pre-treatment section acid dip pickle.
Background technology
Resting period, longer cold-rolled strip surface can get rusty, and the position got rusty when zinc-plated can not plate zinc, produce plating leakage
Defect；Usually acid dip pickle is set to get rid of the iron rust on cold-rolled strip in preceding processing section in galvanization production line, it is known that
Acid dip pickle generally has following defect：First, acid solution is slack-off with the time of iron rust generation chemical change when low temperature, causes
The derusting of winter acid solution is less able；2nd, when one layer of greasy dirt is covered on iron rust, acid solution and iron rust contact area are few,
Derusting is not thorough；3rd, acid solution is brought into follow-up electrolytic cell by steel band after acid dip pickle, causes electrolytic cell to be corroded.
The content of the invention
Deficiency, the purpose of this utility model is to provide a kind of zinc-plated pre-treatment section acid dip pickle, includes for more than
Heater box, acid cleaning tank, rinse tank and air knife, can effectively get rid of rapidly the iron rust on cold-rolled strip and avoid acid solution to follow-up
The corrosion of frock.
The technical solution of the utility model is achieved in the following ways：A kind of zinc-plated pre-treatment section acid dip pickle, bag
Containing heater box, acid cleaning tank, rinse tank and air knife, upper and lower in the heater box is each provided with one group of natural gas nozzle, institute
The left side in acid cleaning tank stated is provided with some groups of acid solution jet pipes and brush roll, and the right is provided with acid solution squeeze roller；The drift
The left side in tank-washer is provided with some groups of nature water spray pipes, and the right is provided with water squeeze roller；It is characterized in that：The acid cleaning tank
Left end be provided with the heater box of built-in natural gas nozzle, right end is then provided with rinse tank.
The air knife is arranged on the exit of rinse tank, and mirror symmetry is distributed in steel band both sides up and down.
The utility model is jetted out flames by the natural gas nozzle in heater box to be burnt up greasy dirt and heats cold-rolled strip, then
Iron rust is thoroughly got rid of by the acid solution jet pipe in acid cleaning tank and brush roll combination again, finally by rinse tank by steel strip surface
Acid solution clean up, not only effectively got rid of the iron rust of steel strip surface, it is thus also avoided that the follow-up electrolytic cell of acid liquid corrosion.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
1 is heater box in figure, and 2 be acid cleaning tank, and 3 be rinse tank, and 4 be natural gas nozzle, and 5 be acid solution jet pipe, and 6 be hairbrush
Roller, 7 be acid solution squeeze roller, and 8 be nature water spray pipe, and 9 be water squeeze roller, and 10 be air knife, and 11 be steel band.
Embodiment
Known by Fig. 1, a kind of zinc-plated pre-treatment section acid dip pickle, includes heater box 1, acid cleaning tank 2, rinse tank 3 and air knife
10, the heater box 1, acid cleaning tank 2 and rinse tank 3 are from left to right arranged in order；Setting each up and down in the heater box 1
Have one group of natural gas nozzle 4, jet out flames burn-up steel band 11 on greasy dirt and steel band 11 is heated, the acid cleaning tank 2
The interior left side is provided with some groups of acid solution jet pipes 5 and brush roll 6, and the right is provided with acid solution squeeze roller 7；In the rinse tank 3
The left side be provided with some groups of nature water spray pipes 8, the right is provided with water squeeze roller 9；The air knife 10 is arranged on rinse tank 3
Exit, and about 11 both sides for the steel band that is distributed in of mirror symmetry.
During work, steel band 11 is entered in heater box 1 from the left side, and the natural gas nozzle 4 in heater box 1 jets out flames burning
Fall the greasy dirt of 11 upper and lower surface of steel band, while also heated steel band 11；Steel band 11 enters acid cleaning tank 2 after being come out from heater box 1,
The acid solution jet pipe 5 on the left side sprays acid solution and is scrubbed to the upper and lower surface of steel band 11, then by brush roll 6 in acid cleaning tank 2, accelerates acid solution
With the chemical reaction of iron rust；After some groups of acid solution jet pipe 5 and the pickling of brush roll 6, the iron rust quilt on 11 surface of steel band
It is quick to remove, then squeezed out by acid solution squeeze roller 7 and rinse tank 3 is delivered to after a large amount of acid solutions on steel band 11, the left side in rinse tank 3
Some groups.Natural water spray pipe 8 sprays substantial amounts of Natural Water and washes acid solution remaining on the surface of steel band 11, then passes through water
Squeeze roller 9, which extracts the acid solution of low concentration on steel band 11, transfers out rinse tank 3, and the air knife 10 in 3 exit of rinse tank blows out high pressure
Air, further by sour water scraped clean remaining on steel band 11.
The utility model is jetted out flames by the natural gas nozzle 4 in heater box 1 and burn-up greasy dirt and heats cold-rolled strip 11,
Then combined again by the acid solution jet pipe 5 in acid cleaning tank 2 and brush roll 6 and thoroughly get rid of iron rust, finally by rinse tank 3 by steel
Cleaned up with the acid solution on 11 surfaces, not only effectively got rid of the iron rust on 11 surface of steel band, it is thus also avoided that acid liquid corrosion
Follow-up electrolytic cell.
