Description
Technical field
The utility model relates to automatic producing technology fields, in particular to a kind of for automatically adjusting the device of pH value.
Background technique
For Chemical Manufacture enterprise, Workshop Production usually requires the acid solution or lye of certain pH, but general purchased liquid alkaline/liquid
The concentration of acid, which is greater than, produces required concentration, so needing to adjust before production reduces liquid alkaline concentration.
A certain amount of water is first injected currently, being generally adopted by temporary storage tank, then pump injection liquid alkaline is opened by artificial,
Liquid alkaline mixes in temporary storage tank with water, such as when needing pH value is 10 aqueous slkali, when the value that the pH meter in exit is shown is
When 10, termination of pumping.Since temporary storage tank is larger, liquid alkaline is mixed with water arrives this period at PH meter again, and liquid alkaline is always in injection, institute
There is very big error with this adjusting, artificial opens pump, termination of pumping in the presence of operation control accuracy and human error, and pH value is adjusted just
Circuit sequentially no continuity.The method drawback:
1) continuous production is not strong；
2) pH meter feedback needs a period of time to adjusting, adjusts and there is very big error；
3) liquid alkaline injection rate artificially need to be controlled according to pH meter feedback, control effect is undesirable.
The device for producing the problems such as discontinuous, preparation error is big, not easy to control upper at present is able to solve therefore, it is necessary to a kind of.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts, providing one kind being capable of intensified continuity life
It produces, enhancing automation control, reduces manual operation, makes the liquid alkaline concentration adjusted more accurately for automatically adjusting the dress of pH value
It sets.
To achieve the goals above, the device for automatically adjusting pH value of the utility model has following constitute:
The device includes proportion slot, and the proportion slot is connected separately with inlet tube and water inlet pipe, the proportion
Slot is provided with outlet, and described is provided with pH meter with exit, and the inlet tube is provided with the first pneumatic operated valve, the pH
Meter is arranged to control the aperture of first pneumatic operated valve according to the real-time detection value of pH meter.
Preferably, the outlet of the proportion slot is connected with temporary storage tank.
Preferably, the second pneumatic operated valve is provided between proportion slot and the temporary storage tank, the pH meter setting
At the switch according to the real-time detection value of pH meter control second pneumatic operated valve.
Preferably, inlet tube described in the pH meter control and water inlet pipe are normally opened pipeline.
Preferably, the inlet tube is into alkali liquor pipe or into acid solution pipe.
Preferably, the pH meter is set to the lower section of the proportion slot.
Using the utility model for automatically adjusting the device of pH value, can be produced with intensified continuity, enhancing automation
Control reduces manual operation, keeps the liquid alkaline concentration adjusted more accurate, carries out place mat for subsequent production；Reduce Field Force's work
It measures, keeps the stabilization of pH.

Specific embodiment
In order to more clearly describe the technology contents of the utility model, carry out combined with specific embodiments below into one
The description of step.
As shown in Figure 1, being the utility model for automatically adjusting the device of pH value, wherein the device includes proportion
Slot 1, the proportion slot are connected separately with inlet tube 2 and water inlet pipe 3, which, should for conveying high alkali liquid or concentrated acid liquid
Water inlet pipe is for conveying diluted water；The proportion slot is provided with outlet 4, and described is provided with pH meter 5, institute with exit
The inlet tube 2 stated is provided with the first pneumatic operated valve 6, and the pH meter is arranged to control described the according to the real-time detection value of pH meter
The aperture of one pneumatic operated valve 6.
For example, passing through pH meter after respectively mixing liquid alkaline and water injection proportion slot by inlet tube and water inlet pipe
On air real time test, when the real-time detection pH value of pH meter feedback is greater than 10, pH meter controls 6 aperture of the first pneumatic operated valve and reduces, when
When the real-time detection pH value of pH meter feedback is less than 10, pH meter controls 6 aperture of the first pneumatic operated valve and increases, to realize automatic adjustment note
The ratio of the liquid alkaline and water that enter, without manual operation, to reach required pH value.
Also it can be adjusted according to the needs into the pH of other numerical value including acidic value.
In a kind of preferably embodiment, the outlet of the proportion slot is connected with temporary storage tank 7.
In a kind of preferably embodiment, the second pneumatic operated valve is provided between proportion slot and the temporary storage tank
8, the pH meter is arranged to control the switch of second pneumatic operated valve according to the real-time detection value of pH meter.When pH meter is examined in real time
After the pH value of survey reaches requirement, pH meter is controllable to open the second pneumatic operated valve 8, is allowed to put into production.
In a kind of preferably embodiment, the pH meter control inlet tube and water inlet pipe are normally opened pipeline.
In a kind of preferably embodiment, the inlet tube is into alkali liquor pipe or into acid solution pipe.
In a kind of preferably embodiment, the pH meter is set to the lower section of the proportion slot.
Using the utility model for automatically adjusting the device of pH value, can be produced with intensified continuity, enhancing automation
Control reduces manual operation, keeps the liquid alkaline concentration adjusted more accurate, carries out place mat for subsequent production；Reduce Field Force's work
It measures, keeps the stabilization of pH.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still may be used
With the spirit and scope that various modification can be adapted and converts without departing from the utility model.Therefore, the description and the appended drawings should be considered
It is illustrative and be not restrictive.
