Description
Technical field
The invention belongs to pickling technical field, relate to a kind of pickling tank processed on steel-sheet pickling unit.
Background technology
Traditional pickling operation process is dip pickling method, is dipped in acid solution by metallic substance, comes off after allowing the oxide compound of acid solution and metal material surface react from the surface of metallic substance.In acid cleaning process, the reactant of acid solution and oxide compound still can form the more weak protective layer of an acidity in metallic surface, and progressively slowly spreading and could complete pickling operation gradually along with reactant, makes acid cleaning process need the time of at substantial.
Have at present and a kind of spray acid wash, adopt and spray the time that acid wash can shorten pickling, but evenly cannot be injected into each piece of metal sheet surface, so its pickling effect is not as good as dip pickling method due to spray gun.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of pickling tank processed on steel-sheet pickling unit.
Object of the present invention realizes by following technical proposal: a kind of pickling tank processed on steel-sheet pickling unit, comprise the cell body for holding pickle solution, be positioned at the dividing plate of cell body, air pump and water pump, it is characterized in that, described dividing plate have some mesh, cell body is divided into pickling chamber and air blast chamber by dividing plate, exhaust duct is provided with in described air blast chamber, exhaust duct have some escape pipes, it is outer and be interconnected with the air outlet of air pump that described exhaust duct one end passes cell body, described cell body have water outlet and water-in, described water outlet is interconnected by the input terminus of rising pipe and water pump, water-in is interconnected by water inlet pipe and water delivery side of pump.
Cell body is square, and residing high position of the water outlet on cell body and water-in be the half of cell body height, cell body hold that pickle solution is not less than its height at every turn 2/3rds, the one end being positioned at the air outlet tube of cell body is seal.Start water pump, the pickle solution in cell body can flow out from the water outlet cell body, then flows to water pump by rising pipe, is finally flowed in cell body from the water-in cell body by water inlet pipe again.Static pickle solution in cell body is flowed, improves steel-sheet pickling efficiency.Restart air pump in addition, air pump is supplied gas toward exhaust duct, and gas is jet in cell body by escape pipe, and gas percussion surface of thin steel sheet makes oxide film come off in impact process, further enhances pickling efficiency.Wherein the mouth of pipe of escape pipe is smaller, and the pickle solution in cell body cannot flow in escape pipe.
In above-mentioned a kind of pickling tank processed on steel-sheet pickling unit, described dividing plate is horizontally placed in cell body, and above-mentioned mesh is equally spaced on dividing plate.
Mesh on dividing plate makes the pickle solution in pickling chamber and air blast chamber keep circulation, mesh is equally spaced and the circulation of the pickle solution of certain can be avoided on dividing plate fast or slow, indirectly improve steel-sheet pickling efficiency, in turn ensure that the consistence of steel plate each position pickling efficiency.
In above-mentioned a kind of pickling tank processed on steel-sheet pickling unit, described escape pipe circumference is distributed on exhaust duct.
Adopt above structure, namely strengthen air output, turn improve the dispersed of air output.
In above-mentioned a kind of pickling tank processed on steel-sheet pickling unit, cell body inwall is provided with electronics PH and counts.
Staff can judge the acidic value of pickle solution in cell body by electronics PH meter, can supplement suitable acid solution in time to cell body, makes the acidity of pickle solution in cell body keep constant, thus continues to have good pickling ability.
In above-mentioned a kind of pickling tank processed on steel-sheet pickling unit, have water shoot bottom cell body, water shoot place is provided with valve.
Adopt above structure, be convenient to the cleaning of staff to the pickle solution after use in cell body.
Compared with prior art, the advantage of the pickling tank on this processing steel-sheet pickling unit is that this processing steel-sheet pickling unit first utilizes water pump that the pickle solution in cell body is circulated, and then utilize air pump toward air-blowing in exhaust duct, jet in cell body by escape pipe, the oxide compound accelerating pickle solution and surface of thin steel sheet reacts, namely ensure that the homogeneity of steel sheet pickling, accelerate again steel-sheet pickling speed.
