The 2nd of 3 is to the 10th group.Wherein, overflow spray structure includes the stagewise above strip steel 3
Lower jet pipe 2 corresponding with stagewise flow structure below flow structure, strip steel.With prior art
In bonderizing, spray equipment is compared, as it is shown in figure 1, the length direction along strip steel arranges
10 groups of jet pipes, including 10 upper 1,10 lower jet pipes 2 of jet pipe.The present invention will be along strip steel cloth
The upper jet pipe 1 of the first group of jet pipe put changes the stagewise flow structure in the present invention into (such as figure
2)。
Shown in Fig. 3, stagewise flow structure includes 5, two grades of guiding gutters of one-level guide shell
6, three grades of overflow platforms 7, one-level guide shell 5 is axially horizontal direction, one-level guide shell 5
Sidewall upper be provided with water inlet pipe 4, water inlet pipe 4, lower jet pipe 2 are by circulating pump 12 and phosphorus
Change tank 13 to be connected, circulating pump 12 Phosphating Solution in phosphatization tank 13 is pumped into water inlet pipe 4 with under
In jet pipe 2, wherein, circulating pump 12 is connected in parallel to spare circulating pump 14, works as circulating pump
12 break down, and start spare circulating pump 14.Phosphatization tank 13 and water inlet pipe 4 pass through flexible pipe
11 are connected, and flexible pipe 11 uses flange arrangement 9 to dock with water inlet pipe 4, flange arrangement 9
Being provided with hands valve 10, hands valve 10 controls being passed through of Phosphating Solution and is passed through with stopping.One-level guide shell
The lower wall of 5 is provided with two grades of guiding gutters 6 diagonally downward, and two grades of guiding gutters 6 include left plate
6.1 form " V " type, two grades of guiding gutters with right plate 6.2, left plate 6.1 and right plate 6.2
The end of right plate 6.2 is connected with three grades of overflow platforms 7, strip steel width 1m, two grades of guiding gutters 6
Width C 1 is 1.2m, and the width C 2 of three grades of overflow platforms is 1.2m, one-level guide shell 5 times
Sidewall has flow-guiding mouth 5.1, and Phosphating Solution flows into two grades of guiding gutters 6 by flow-guiding mouth 5.1, leads
Head piece 5.1 is 1.1m along length L of the axial direction of one-level guide shell 5, by flow-guiding mouth 5.1
Length, the width of two grades of guiding gutters 6, the width design of three grades of overflow platforms 7 obtains all than band
The width of steel is a little longer, also ensures that strip steel is at width all and phosphorus while material saving
Change liquid contact.
As it is shown on figure 3, wherein, one-level guide shell 5 is cylindrical barrel shape, one-level guide shell 5
Internal diameter d be 50mm, the one-level guide shell 5 of this cylindrical barrel shape as first-level buffer fill
Putting and make the Phosphating Solution pumped into be buffered by the arc structure of cylinder inwall, two grades of guiding gutters 6 are left
Side plate 6.1 is 30 ° with the angle of horizontal direction, the left plate 6.1 of two grades of guiding gutters and right side
The angle α of plate 6.2 is 120 °, two grades of guiding gutter right plates 6.2 and three grades of overflow platforms 7
Angle β is 120 °, and the width b of flow-guiding mouth 5.1 is 2mm.Select the one of 50mm internal diameter
Level guide shell 5, left plate 6.1 tilts 30 °, and α angle is 120 °, and it is root that β angle is 120 °
The optimal parameter that border operating experience draws factually, Phosphating Solution, through one-level guide shell 5, is led for two grades
Chute 6, after three grades of overflow platforms 7, flow velocity is 1m3/ h, this flow velocity is the anti-of optimal strip steel
Answering flow velocity, too fast Phosphating Solution is too fast with the reaction of strip steel upper surface, crosses slow Phosphating Solution and band
The reaction of steel upper surface is incomplete.
As in figure 2 it is shown, water inlet pipe 4 is located at the middle part of one-level guide shell 5 sidewall axial direction,
So ensure that the flow velocity of the Phosphating Solution of one-level guide shell 5 the right and left is the same, it is ensured that at phosphatization
The homogeneity of the phosphating coat of the belt steel surface after reason.
Wherein, as in figure 2 it is shown, Phosphating Slot 8 side has refluxing opening 8.1, refluxing opening 8.1
Being connected with phosphatization tank 13 by return duct, phosphatization tank 13 is placed in the lower section of Phosphating Slot 8, this
Sample overflow and the Phosphating Solution sprayed can be back to phosphatization tank 13 from refluxing opening 8.1, so
The flow structure above strip steel 3 and the lower jet pipe below strip steel 3 is pumped into afterwards by circulating pump 12
In 2, forming closed circuit, Phosphating Solution repeats recycling, does not results in the waste of Phosphating Solution.
The running of this device is: combine Fig. 2, shown in Fig. 3, opens hands valve 10, logical
Cross circulating pump 12 and the Phosphating Solution in phosphatization tank 13 pumped in water inlet pipe 4 and lower jet pipe 2,
One branch road of the Phosphating Solution of high pressure upwards sprays from the nozzle of lower jet pipe 2, another branch road
Flowed into by water inlet pipe 4 and one-level guide shell 5 carries out first-level buffer, the phosphorus after first-level buffer
Change liquid to be flowed down along the left plate 6.1 of two grades of guiding gutters 6 by flow-guiding mouth 5.1, form two grades
Buffering, when Phosphating Solution arrives right plate 6.2 when, Phosphating Solution is piled up in " V " type groove,
When being stacked into the position of the peak exceeding right plate 6.2, Phosphating Solution is along three grades of overflow platforms 7
Flow down, form continuous, slow, stable Phosphating Solution waterfall, with strip steel 3 upper surface.
The Phosphating Solution that overflow and spray flow down flows in Phosphating Slot 8, by the backflow of Phosphating Slot 8
Mouth 8.1 passes back in phosphatization tank 13.After bonderizing, close hands valve 10, phosphatization
Liquid stops being passed through water inlet pipe 4, and Phosphating Solution no longer overflows from two grades of guiding gutters 6 and forms water waterfall,
And do not have water droplet and drip downwards formation mottle.
Use the phosphatization plate that the device reduces color spot failures, from 2014 to 2015 years
Within 2 years, produce phosphatization plate 1.6 ten thousand tons, the phosphorus of the color spot failures wherein caused because of nozzle splash altogether
Changing plate and reach more than 2400 ton, the phosphatization plate of this defect is the 15% of total phosphatization plate；Within 2016, send out
After bright enforcement, produce 3560 tons of phosphatization plates altogether, the color spot failures caused without splash
Phosphatization plate, has stopped completely because splash causes color spot failures to produce.
