The utility model content
The utility model technical problem to be solved is to overcome the defective of prior art, and a kind of passivation device of high galvanized sheet is provided, and it can effectively control the thickness of passive film, improves the homogeneity of passivation.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of passivation device of galvanized sheet is provided, comprise with passivating solution be coated on band steel two sides with the vertical roller coating machine that forms passive film, be located at the stoving oven of will the band steel drying vertical roller coating machine top, band steel after will drying carries out at least one air cooling equipment of refrigerative.
Particularly; Said stoving oven comprises vertically disposed body of heater, and the bottom of said body of heater is the preheating zone, and the middle part of said body of heater and top are the heating zone; Said preheating zone sidewall is communicated with smoke discharging pipe, and the sidewall of said heating zone is provided with the burner that is communicated with outside Sweet natural gas.
Particularly, said air cooling equipment comprises stand, is located at blower fan on the said stand, being connected with said blower fan can be to the band steel refrigerative airduct road of drying.
Further, said air cooling equipment is four.
Further, said passivation device comprises that also the band steel will be with the deviation correcting device of steel centering before getting into vertical roller coating machine.
Further, said deviation correcting device comprises a frame, the unit of being located at correction roller on the frame, being positioned at the transmitter on the said frame and being connected and controlling the correction roller with said transmitter.
In the utility model, in the utility model, adopt vertical roll coating model to replace original spray and extract mode, on the one hand, avoid passivating solution high temperature crystallization obstruction shower nozzle in the spray mode; On the other hand, can control thickness, make that the passivating solution thickness is more even through pressure, rotating speed that adjustment is coated with roller; Simultaneously, utilize reasonably oven dry and cooling apparatus further to guarantee passivation effect.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the passivation device that is used for galvanized sheet that provides of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, the structural representation of a preferred embodiment of the passivation device that is used for galvanized sheet that provides for the utility model.The passivation device of said galvanized sheet, comprise with passivating solution be coated on band steel both sides with the vertical roller coating machine 100 that forms passive film, be located at the stoving oven 200 of will the band steel drying vertical roller coating machine 100 tops, band steel after will drying carries out at least one air cooling equipment 300 of refrigerative.In the utility model, the roller coating machine of vertical roller coating machine for purchasing, it mainly comprises the pallet that is used to hold passivating solution, is located at getting the liquid roller and passivating solution is coated on the coating roller on the band steel on the pallet.Get the liquid roller through roller rotation by in the pallet passivating solution being taken on the coating roller, when its rotating speed was high more, the medicament viscosity was big more, with on passivating solution many more, get the roller rotating speed and generally be controlled to be 30% to 70% strip speed.The rotating speed of coating roller is directly proportional with the thickness of passive film, and the rotating speed that generally applies spiral shell is controlled at 130% to 200% strip speed.This vertical roller coat machine operation is simple with maintenance; Adopt vertical roll coating model to replace original spray for thickness and extract mode, utilize the pressure between coating roller and the band steel that passivating solution is coated on the band steel, on the one hand; Avoid passivating solution high temperature crystallization obstruction shower nozzle in the spray mode; On the other hand, can control thickness, make that the passivating solution thickness is more even through pressure, rotating speed that adjustment is coated with roller; Simultaneously, utilize reasonably oven dry and cooling apparatus further to guarantee passivation effect.
Further; Stoving oven 200 comprises vertically disposed body of heater 210, and the bottom of body of heater 210 is the preheating zone, and the middle part of body of heater 210 and top are the heating zone; The preheating zone sidewall is communicated with smoke discharging pipe 220, and the sidewall of heating zone is provided with the burner (not shown) that is communicated with outside Sweet natural gas.Adopt this combustion of natural gas oven dry, the highest bake out temperature can reach 120 ℃, satisfies greatly and adopts the compound chromium-free passivation liquid of organic/inorganic, and the band steel needs the requirement of temperature more than 80 ℃.
In the present embodiment, air cooling equipment 300 comprises stand 310, be located at blower fan 320 on the stand 310, being connected with blower fan 320 can be to the band steel refrigerative airduct road (not shown) of drying.Adopt above-mentioned refrigerating unit, can cool off the band steel after the oven dry fast, reduce its temperature.
Further, according to actual needs, in the present embodiment, along on the band steel orbit four typhoon device for cooling 300 being set.
