Detailed description of the invention
Fig. 1 is structural block diagram of the invention.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments the present invention is described in detail.It should be noted that in the feelings not conflicted
Under condition, the feature in following embodiment and embodiment can be combined with each other.
As shown in Figure 1, a kind of galvanizing inactivating liquid generating apparatus, including ion-exchanger and PH regulating tank again, the ion is handed over
The liquid inlet of parallel operation is connected to deactivation slot liquid outlet, and liquid outlet is connected to PH regulating tank, and the PH regulating tank is also connected by water pump
The logical container equipped with pH value adjustment liquid, wherein be provided with pH value probe in the PH regulating tank, pH value is provided with outside PH regulating tank
The signal input part of adjusting controller, pH value adjustment controller connects the PH probe, the control signal of pH value adjustment controller
Output end connects water pump on off controller, and water pump on off controller connects water pump, and the pH value adjustment controller is for working as pH value
The exceeded backward water pump on off controller of the pH value of probe collection issues the signal of starting water pump, and the Xiang Shui after pH value complies with standard
Pump on off controller issues the signal to switch off the pump, and the liquid outlet of such loop control, the PH regulating tank also enters with deactivation slot
The connection of liquid mouth passes through deactivation slot liquid inlet circulation by the solution that the purification of PH regulating tank regulates pH value again and flows into deactivation slot.
Wherein, the shell of pH value adjustment controller is mounted on outside PH regulating tank, and control circuit board is provided in shell, control
Control chip is provided on circuit board, if select control chip without AD conversion or D/A conversion module, by pH value probe
The PH analog electrical signal of output is transferred to after AD conversion module is AD converted, with the preset PH stored in control chip
Value is compared, when the pH value of pH value probe collection is bigger than preset value, the control signal of control chip output starting water pump
To the D/A conversion module, control digital signal is converted into control analog electrical signal feed pump on off controller, and in pH value
The signal to switch off the pump is issued after complying with standard to water pump on off controller, relay can be used in water pump on off controller, connects
The settable fracture of the power supply of water pump, the movable contact of one end connection relay of fracture, the output end of D/A conversion module connect relay
The coil of device, and obtain electric late contact in coil and be attracted, the both ends of supply lines fracture are connected to by movable contact, and water pump is opened in realization
Open control.Certainly, it is contemplated that the signal exported from D/A conversion module is minimum, can amplify in the output connection signal of D/A conversion module
Device, the coil after signal amplifier amplifies again with relay are connect.If, can also be in the lesser situation of received pH value
In the front end matched signal amplifier of AD conversion module, if the control chip used carries AD conversion and DA conversion function, then
AD conversion module and D/A conversion module can be omitted.
Since the solution in deactivation slot is in acidity, and wherein most foreign ion is Zn2+And Zn2+Ion, by from
Sub- exchanger removes major part Zn therein2+And Zn2+Ion carries out contamination precipitation by precipitating reagent, flows from ion-exchanger
The solution entered in PH regulating tank has had been removed Zn substantially2+And Zn2+Equal foreign ions, ion-exchanger can be used on the market often
Ion-exchanger.
Holding in the container of water pump connection is the alkaline solutions such as sodium hydroxide.
The PH regulating tank is also communicated with dashpot, is led to the solution that the purification of PH regulating tank regulates pH value by dashpot
Dashpot liquid outlet circulation is crossed to flow into deactivation slot.Dashpot can be such that the passivating solution after adjusting pH value more fully stirs
It is even, influence of the passivating solution to deactivation slot that be further reduced that treated.
On the connecting pipe of the deactivation slot and the ion-exchanger, the ion-exchanger and the PH regulating tank
On connecting pipe, flow control valve is provided on the connecting pipe of the dashpot and the deactivation slot.It is adjusted by flow
The flow of valve regulation liquid, or when needing thorough drain or cleaning corresponding groove body, flow control valve can be closed.
The ion-exchanger is also respectively communicated with the washing lotion bucket for holding ion-exchanger cleaning solution and holds the pure of pure water
Bucket.The connecting pipe of ion-exchanger and washing lotion bucket and pure water cylinder is respectively arranged with flow control valve.When ion-exchanger needs
When cleaning, cleaning solution and water can be evacuated to respectively by water pump after being cleaned in ion-exchanger and be discharged, wherein cleaning solution
Hydrochloric acid can be selected because passivating solution be it is acid, cleaning solution also must be it is acid, the cost of hydrochloric acid is low and liquid waste processing
It is easy.
Generating apparatus, the foreign ion for realizing passivating solution remove the galvanizing inactivating liquid of the present embodiment again, reduce passivating solution
Discharge, the on-line automatic pH value for adjusting processing post-passivation liquid, without manually adjusting, treated, and passivating solution be can be used directly, no
Influence normal production.
Embodiment belonging to above only expresses concentration embodiment of the invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as, it is noted that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore the scope of protection of the patent of the invention shall be subject to the appended claims.
