Description
Technical field
The utility model belongs to industrial processing technology field, can control liquid reactants pH value in time more particularly, to a kind of
Reaction unit.
Background technique
In 2D production of resins, reaction environment pH is very big on the influence of the extent of reaction of reaction mass, needs timely and accurately
Control the range of pH value in reaction.It mostly uses liquid alkaline storage tank to store liquid alkaline at present, a bottom valve is filled under storage tank and is connected to reaction kettle, is led to
It crosses and opens bottom valve repeatedly manually, liquid alkaline is added drop-wise in reaction kettle.The unlatching of this process valve is more frequent, the pH value of reactant
Range fluctuation is very big, it is easy to cause, operate tired, the drawbacks such as stability difference of product.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, and design is closed
Reason, the reaction unit easy to use that liquid reactants (2D resin) pH value can be controlled in time, group between its pH meter and control valve
At closed-loop control, the real-time monitoring and regulation of pH in reaction kettle can be avoided traditional artificial Operation delay, cause to react
The range of the pH value of object fluctuates big problem,
In order to achieve the above purposes, the technical solution adopted by the utility model is: it include liquid alkaline storage tank, pneumatic control valve,
Peristaltic pump, reaction kettle, pipeline pump, pH meter, the reaction kettle lower end are connected with pipeline pump, and in the cooperation the following group of circulating line
At material in reactor loop structure；Wherein, pH meter is installed on circulating line, real-time pH detection is carried out to object in kettle；It is described
The upper end of reaction kettle connected by pneumatic control valve, peristaltic pump and liquid alkaline tank bottom, and pneumatic control valve, peristaltic pump and pH
Meter interlocking.
Preferably, the pH meter and pneumatic control valve, peristaltic pump three's anabolic reaction kettle materials inside pH value close
Ring control.
Preferably, the pneumatic control valve, peristaltic pump synchronize gearing by controlling to adjust.
Preferably, the pneumatic control valve, peristaltic pump, pipeline pump, pH meter volume are connected by fieldbus and controller
It connects, realizes long-range monitoring.
After adopting the above structure, the utility model has the beneficial effect that described in the utility model a kind of can control liquid in time
The reaction unit of precursor reactant object pH value, the closed-loop control formed between its pH meter and control valve can be real to the pH in reaction kettle
When monitoring and regulation, avoid traditional artificial Operation delay, the range of the pH value of reactant caused to fluctuate big problem, this is practical
It is novel to have structure simple, setting rationally, the advantages that low manufacture cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols:
Liquid alkaline storage tank 1, pneumatic control valve 2, peristaltic pump 3, reaction kettle 4, pipeline pump 5, pH meter 6.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, present embodiment adopts the following technical scheme that it includes liquid alkaline storage tank 1, pneumatic tune
Valve 2, peristaltic pump 3, reaction kettle 4, pipeline pump 5, pH meter 6 are saved, 4 lower end of reaction kettle is connected with pipeline pump 5, and is recycling
Matter Transfer structure in composition reaction kettle 4 under the cooperation of pipeline；Wherein, be equipped on circulating line pH meter 6 to object in kettle into
The detection of row real-time pH；The upper end of the reaction kettle 4 is connect by pneumatic control valve 2, peristaltic pump 3 with 1 bottom of liquid alkaline storage tank, and
Pneumatic control valve 2, peristaltic pump 3 and pH meter 6 interlock；The pH meter 6 and pneumatic control valve 2,3 three's anabolic reaction of peristaltic pump
The closed-loop control of 4 materials inside pH value of kettle.
Wherein, the pneumatic control valve 2, peristaltic pump 3 synchronize gearing by controlling to adjust；The pneumatic adjusting
Valve 2, peristaltic pump 3, pipeline pump 5, pH meter volume 6 connect with controller by fieldbus, realize and remotely monitor.
The working principle of this specific embodiment:: circulation is beaten to material in kettle by pipeline pump, pH meter is timely in pipeline
The real-time pH value of material is measured, the pH of material in reactor is real by opening liquid alkaline storage tank bottom valve, and starting peristaltic pump
It is existing, by setting pH value, pH meter and peristaltic pump, pneumatic control valve are interlocked.Real-time pH value deviates corresponding when setting value
Peristaltic pump, pneumatic control valve can start accordingly.To realize the stabilization of pH value range.
After adopting the above structure, present embodiment has the beneficial effect that the closed loop formed between its pH meter and control valve
Control, can avoid traditional artificial Operation delay, lead to the pH value of reactant to the real-time monitoring and regulation of pH in reaction kettle
