Description
Technical field
The present invention relates to acidification field, be used for acidification reaction, particularly to a kind of self-regulating acidifying cylinder.
Background technology
So-called acidifying be exactly add in the solution hydrion make the pH value of solution diminish and the acid that adds will not with in original solution
Ion react.Such as: the potassium permanganate solution of acidifying, in potassium permanganate solution, the irreducibility such as dilute sulfuric acid are i.e. added
Acid regulation acidity is to increase the oxidisability of potassium permanganate solution.At present, in metal working process, need to carry out acidification step,
But existing acidifying cylinder is all to utilize acidizing materials to make, prevents being acidified cylinder and be in use corroded, and really carry out

Survey contact works.
By so arranging, when detecting the closing of contact, testing circuit is started working, when detecting that pH value is higher, that
Judge now to need to be automatically replenished acidifying solution, and be automatically replenished, when PH is to when being reduced to required pH value, be automatically stopped benefit
Fill, it is ensured that acidizing effect is preferable, and same, decontrol detection contact and can also stop supplementing, prevent from supplementing excess.
Further: described base modules includes being sequentially connected in series the first resistance of setting, the second resistance and the 3rd resistance, institute
State the first resistance and node that the second resistance couples provides reference voltage.Ensure use time can improve use safety and can
By property.Misoperation will not be caused because of current spike, or resistance burns out.
Further: described 3rd resistance is adjustable resistance.By the setting of the 3rd resistance, user may be according to safety
Reference voltage is adjusted by parameter and ambient conditions, it is possible to the sensitivity of regulation PH testing circuit.
Further: described execution module includes comparator, the positive input terminal of described comparator receives sampled voltage, described
The negative input end of comparator receives reference voltage, when sampled voltage is more than reference voltage, exports alkalescence feedback signal.Pass through
The setting of comparator, cost is relatively low, and response speed is very fast, is not easily susceptible to magnetic interference.
Further: described first resistor coupled in parallel is provided with anti-interference module, described anti-interference module includes be arranged in series
Four resistance and switch element, the controlled terminal of described switch element is coupled to alkalescence feedback signal.If PH sensor is in sampling
Time sampled voltage disturbance occurs and is in again the situation near reference voltage, then easily cause send abnormal signal execution
Equipment perseveration, affects service life of equipment, so when comparator output alkalescence feedback signal, dragging down reference voltage
Size, its principle is as follows, and PH comparison module is output as high level (alkalescence feedback signal), controls switching tube conducting, is equivalent to
At one the 4th resistance of the first resistor coupled in parallel, be equivalent to reduce so that the equivalent resistance of the first resistance, so the first electric resistance partial pressure
The voltage obtained increases little so that reference voltage increases, and prevents from causing subsequent conditioning circuit because sampled voltage floats near reference voltage
Perseveration and damage.
Further: also including that indicating circuit, described indicating circuit include light emitting diode, described light emitting diode is controlled
In performing signal work.Current PH state can be reminded in use, it is ensured that user is understood.
Further: in described indicating circuit, described light emitting diode has been arranged in series time-delay relay coil, described
Ion earthing unit also includes time-delay relay normally opened contact and the honeybee that warning circuit, described warning circuit include being arranged in series
Ring device, during described time-delay relay normally opened contact Guan Bi, described buzzer obtains electric work.
By using technique scheme, when normally using, all original modules normally work, PH sensor detection ion
PH near earthing pole, when PH is less than preset value, performs module output and performs signal, control LEDs ON, so make
User avoids the need for just can being detected PH situation by observation port, and will not judge to produce error because of artificial, is more beneficial for making
User's faster unusual circumstance.
In sum, the method have the advantages that by so arranging, when detecting the closing of contact, detection electricity
Start working in road, when detecting that pH value is higher, then judges now to need to be automatically replenished acidifying solution, and is automatically replenished, works as PH
To when being reduced to required pH value, it is automatically stopped supplementary, it is ensured that acidizing effect is preferable, and same, decontrols detection contact and also may be used
To stop supplementing, prevent from supplementing excess.
