Description
Technical field
The utility model and Waste Acid From Hua Cheng Foil apparatus field, particularly a kind of energy-saving Waste Acid From Hua Cheng Foil process units.
Background technology
The effect of Waste Acid From Hua Cheng Foil pre-treatment at present：
1. aqua oxidation film is initially formed in aluminium foil surface, then in follow-up anode oxidation process, aqua oxidation film
Dehydration generation crystal formation AL2O3, carries out to save during anodic oxidation in a cell compared to directly etching paper tinsel in the presence of highfield
Energy 50% or so；
2. due to the protection of surface hydration film, in anode oxidation process, aluminium ion is not readily dissolved in electrolyte, is reduced
The concentration of aluminium hydroxide, ensure that the limpid of tank liquor in the decay of capacity and tank liquor；
3. key control point：Because fine aluminium is very active, it requires that hydration-treated uses pure water, and prevent the dirt of impurity
Contaminate, the generation of aqua oxidation film can be prevented if the caustic acid such as phosphate of emblem amount, causes the failure of follow-up anodic oxidation；
4. hydration-treated temperature is higher theoretically, the aqua oxidation film quality of formation is better, and follow-up chemical conversion quality can be more
It is good, but general control is at 97 degree or so in big production, in favor of steady production.
In order to meet temperature requirement above, the pre-treatment of actual production line must is fulfilled for two conditions：First, meet temperature
97 degree of requirements of degree；Second, meet to change fresh pure water.So must there are enough thermals source to meet temperature in preceding processing, we
Thermal source have two approach：The electric current of first second level is usually melted into after the big distribution roller feed of preceding before processing along aluminium
Paper tinsel, by pre-treatment groove to the electrolytic bath of back two (two-stage electric current is in more than 2000A).Second is exactly inside preceding processing groove
Heating tube (or steam pipe) is installed.The temperature of pre-treatment is result in plus the fresh pure water of supplement constantly to be reduced, and is being added
Upper Geography elevational position is actual higher, and boiling temperature does not reach 97 degree (there was only 92 degree in Sichuan).So pre-treatment groove
Heating tube is almost kept on all, to meet the requirement of technological temperature.It is more and the power of the heating tube of production line is at least 36KW
Reach 54KW, and the operating cost of identical board also has very big difference in board operation.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided one kind being capable of energy-saving Waste Acid From Hua Cheng Foil production dress
Put.
The technical solution adopted in the utility model is：
A kind of energy-saving Waste Acid From Hua Cheng Foil process units, including be sequentially connected rinsing bowl, electrolytic bath A, electrolytic bath B, pre-treatment
Groove, paper tinsel machine, collecting tank and sewage collecting box are sent, its innovative point is：The rinsing bowl is consolidated by return duct and sewage collecting box
Fixed to connect, all longitudinally disposed coiled pipe inside the electrolytic bath A, electrolytic bath B, the pre-treatment groove passes through flush pipe and coiled pipe
It is fixedly connected, the heat-exchange device of coil pipe built in one is set in the flush pipe, the lower end of the pre-treatment groove sets a drain
To manage, an accurate filter and a booster pump are set on the catheter, the accurate filter front and back end all sets a pressure gauge,
A magnetic valve A is respectively set before and after the catheter, the upper end of the accurate filter is connected by communicating pipe with pre-treatment groove, described
The lower end of accurate filter is connected by liquid back pipe with return duct, and a magnetic valve B, institute are all set on the communicating pipe and liquid back pipe
State pre-treatment groove to be fixedly connected with collecting tank by overflow pipe, hot water is collected in the collecting tank and is rinsed for extraneous board.
Further, the collecting tank also connects with return duct.
The beneficial effects of the utility model are as follows：
The utility model is improved to existing apparatus, not only provides one with the less thermal source of pre-treatment Temperature Difference Ratio to add
The pure water added of hot pre-treatment, and aluminium hydroxide caused by pre-treatment and aluminium powder can be constantly removed, keep pre-treatment
Water it is limpid, reduce the amount for adding water of pre-treatment, further reduce the heat time.
