In be acidic liquid, be weak base or neutral liquid in pre- immersion trough, be akaline liquid in electroplating bath, be akaline liquid in accumulator tank,
It is then accumulator tank before level V rinsing bowl, is activated bath before fourth stage rinsing bowl, then level V rinsing bowl and fourth stage rinsing bowl
It is connected, the like, fourth stage rinsing bowl is connected with third level rinsing bowl, and third level rinsing bowl is connected with second level rinsing bowl,
Second level rinsing bowl is connected with first order rinsing bowl.
Additionally, refining to the plating line in examples detailed above, wherein degreasing tank includes that three contain degreaser
Cell body three oil removal treatments of common Jing rows, the first rinsing bowl includes that the cell body of two splendid attire liquid is washed twice altogether, descaling bath
Three pickling are carried out altogether including the cell body of three splendid attire spent pickling acids, and the second rinsing bowl includes the common Jing of cell body of two splendid attire liquid
Row is washed twice, and electrolysis bath includes that the cell body of a splendid attire electrolyte carries out altogether once electrolytic, and the 3rd rinsing bowl includes two Shengs
The cell body of dress liquid is washed twice altogether, and the cell body of one splendid attire liquid of activated bath treasure-house is activated successively altogether, the 4th water
Washing trough includes that the cell body of a splendid attire liquid is once washed altogether, and pre- immersion trough includes that the cell body of a splendid attire liquid carries out altogether one
Secondary preimpregnation, contains electroplate liquid and is electroplated in electroplating bath, accumulator tank includes the cell body of a splendid attire liquid to the attachment after plating
Residual liquid on device surface is reclaimed, and the second rinsing bowl includes that the cell body of two splendid attire tap waters carries out altogether water twice
Wash.Wherein pre- immersion trough is connected with the 4th washing trench bottom, and accumulator tank is connected with the 5th rinsing bowl the 5th.For connecting with rinsing bowl
Other cell bodies, can substitute rinsing bowl as the connection two ends of the connected mode involved by this utility model, i.e. accumulator tank with
Pre- immersion trough is connected.
Operation principle of the present utility model is following：Workpiece is placed in the washing of the operation rear stage after a certain operation
In groove, if before workpiece is placed in rinsing bowl, the liquid in the rinsing bowl is the liquid in latter rinsing bowl, Acidity of Aikalinity just with work
The liquid that part adhering on surface（Carry due to carrying out the operations such as oil removing, pickling, electrolysis, activation, preimpregnation）Acidity of Aikalinity conversely,
So workpiece carries out washing to reach by the principle of acid-base neutralization washing surface of the work attaching liq in the rinsing bowl
Remove.Certainly, exist liquid Acidity of Aikalinity that workpiece is placed in before rinsing bowl in the rinsing bowl just with the liquid accompanying by surface of the work
The identical situation of Acidity of Aikalinity, but the situation is generally present in the previous link of plating, has no effect in electroplating bath to workpiece
Plating.
With reference to Fig. 4, this utility model part also including tank etc. is stored to the liquid for needing adverse current to go to prime,
When store to it is a certain amount of when, by pumping to prime cell body.The part for completing above-mentioned functions is water cell, including water storage
Pond 1, float switch 3.Wherein water receiver top arranges water inlet pipe 2 and connects with rear stage rinsing bowl or with rear stage washing trench bottom
The connection of other cell bodies, water storage trench bottom arranges the water inlets of 4 pump of outlet pipe 5 and is connected, and the outlet of pump 5 is by connecting tube 6 and higher level
Rinsing bowl is connected with other cell bodies of washing trench bottom connection；Float switch 3 is arranged at outlet pipe 4.Float switch is used
Magnetic force is operated, mechanical connector, is operated simple and reliable.When float switch measured medium buoyant float, float drives main body
It is mobile, while the magnet of the float other end is by the magnet switch motion on control-rod.
Embodiment one
By above-mentioned connected mode, by taking the technological process that Fig. 1 is introduced as an example, to illustrate to the electroplating assembly line.
It is described by the line using zinc-plated in the present embodiment, wherein oil removing adopts 10%NaOH solution, pickling to adopt 30% HCl solution, electricity
Solution is adopted with plating its pH value of identical liquid as alkalescence, and activation adopts 10%HCl solution, and zinc-plated electrolyte used is chloride
Electrolyte basic.
Liquid is loaded with the cell body that at the beginning each rinsing bowl is connected with rinsing bowl, faucet to the 5th rinsing bowl is noted
Water, the workpiece after plating it is recovered and the 5th time washing after flow through the 4th tank, the liquid PH in the first tank to be in alkali
Property；, by pumping to presoaking in cell body, the liquid pH value presoaked in cell body should approximate electroplating bath for liquid in first tank
The pH value of liquid in body, because the liquid pH value in the first tank is alkalescence, therefore presoaks the pH value in cell body also in alkalescence,
And because the pH value of liquid is acidity in activation cell body, therefore have acidic liquid on workpiece to be electroplated, due to presoaking cell body
Interior liquid is alkalescence, is neutral after neutralization just with surface of the work liquid neutralization out in activation cell body, and liquid flow enters the
In two tanks；Liquid in second tank passes through pumping into the 3rd rinsing bowl, because the liquid in electrolysis bath is alkalescence,
Therefore the liquid after third time is washed enters in the 3rd tank in alkaline cocurrent；3rd tank Jing pumpings are to the second washing
In groove, due on workpiece after pickling with the akaline liquid in acidic liquid, with the second rinsing bowl and rear stream enters the 4th water storage
Chi Zhong；First tank Jing pumpings to the first rinsing bowl, this moment liquid is neutrality in the first rinsing bowl, firm to the workpiece after oil removing
Washing step can be carried out well, and the liquid after washing enters water treatment system（As shown in Figure 5）.Wherein tank is from backward
Before be followed successively by the first tank, the second tank, the 3rd tank, the 4th tank.
The plating line that the present embodiment is introduced can be drawn by above-mentioned analysis, by a faucet to last
Level rinsing bowl water filling, rear stage rinsing bowl to previous stage tank transmits liquid, is realized to the clear of surface of the work by acid-base neutralization
Wash.
Embodiment two
For electrolyte is acidic liquid, the liquid gone out in pre- immersion trough is changed into outside acidity, degreasing tank, descaling bath, electrolysis bath,
The Acidity of Aikalinity of liquid is respectively alkalescence, acid, alkalescence, acidity in activated bath.It is same according to the streamline that this utility model is related to
The principle that acid-base neutralization can be based on realizes the cleaning of workpiece.Now holding acidic liquid in the first tank, the second tank,
3rd tank makes it contain neutral liquid due to the akaline liquid of surface of the work attachment after electrolysis, and the 4th tank is due to pickling
Afterwards the acidic liquid of surface of the work attachment makes it contain liquid for acidity, finally acidic liquid first rinsing bowl of inflow and oil removing
The akaline liquid neutralization of the surface of the work attachment after groove oil removing.
