Abstract
The utility model discloses an automatic-control PH neutralization device including a soup conveying pipe, a submerged pump, a soup tank, a frequency converter, a PLC (Programmable Logic Controller), a transmitter, a bulking tank and a PH probe. The submerged pump is installed in the soup tank. One end of the soup conveying pipe is connected with an outlet of the submerged pump while the other end is connected to the bulking tank. An external power source is firstly connected to the frequency converter and is then connected to the submerged pump. The frequency converter is connected to the PLC through a signal line. The PH probe is installed in the bulking tank. The PH probe is connected to the transmitter through a signal line. The transmitter is connected to the PCL through a signal line. A PH value required to be kept in the current production is decided by an operator according to actual conditions in a production process. A value is input to the PLC. Data collected by the PH probe is transmitted to the PLC through the transmitter. An output value is given out for controlling output frequency of the frequency converter. The rotation speed of the submerged pump is decided by the volume of the frequency of the frequency converter, so that the size of the PH value is adjusted.
Description
Technical field
The utility model relates to a kind of control device, and especially a kind of pH controls neutralising arrangement automatically.
Background technology
It is the nonlinear Control problem of a complexity that the pH value is controlled, and seriously non-linear due to titration curve makes the neutralization reaction process differ greatly in different working point gains; In addition, also have the pure delay links such as mixings, measurement in the real reaction process, make control effectively for the pH process comparatively difficult.And the pH value is a very important parameter in industry, agricultural production process; allow the pH value keep a rational value, to the steady production process, improve the quality of products; reduce workman's labour intensity, improving labor productivity and field management level has very positive effect.Therefore, in sugar refinery, the enterprise implement pH value automatic control system tool such as ore dressing plant, chemical industry has very important significance.
Summary of the invention
The purpose of this utility model is to provide a kind of pH and automatically controls neutralising arrangement.
Problem to be solved in the utility model is that existing pH controls the deficiency difficult, that precision is not high.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
The utility model pH controls neutralising arrangement automatically, comprises grug transportation tube, submerged pump, medicine pond, frequency converter, PLC, transmitter, mixing pit and pH probe, and submerged pump is arranged on the inside, medicine pond, and grug transportation tube one end is connected to the submerged pump outlet, and the other end connects to mixing pit; At first external power source is connected to frequency converter, and then is connected to submerged pump, and frequency converter is connected on PLC by signal wire; The pH probe is arranged in mixing pit, and the pH probe is connected on transmitter by signal wire, and the transmitter output terminal is connected on PLC by signal wire.
The PLC model is the Q00J of Mitsubishi, and pH probe model is SY99-GP-PPS-GW.
The utility model has the advantages that: decided the size of the potential of hydrogen of this maintenance in current production according to the actual conditions in production run by the operator, to PLC input numerical value, the data that the pH probe gathers are sent on PLC by transmitter, in PLC, pH set-point and pH actual measured value are compared, processing by intelligent PID algorithm and FUZZY ALGORITHMS FOR CONTROL, provide an output valve, control the output frequency of frequency converter, the size of frequency converter frequency has determined the rotating speed of submerged pump, thereby regulates the size of pH value.Adopt Programmable Logic Controller (PLC) as the control core of whole system, greatly improved the reliability of system.And it is high to have control accuracy, easy to operate characteristics.
Description of drawings
Fig. 1 is the structural representation that the utility model pH controls neutralising arrangement automatically;
In figure: 1, grug transportation tube 2, submerged pump 3, medicine pond 4, frequency converter 5, PLC 6, transmitter 7, mixing pit 8, pH probe.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the utility model pH controls neutralising arrangement automatically, comprises grug transportation tube 1, submerged pump 2, medicine pond 3, frequency converter 4, PLC5, transmitter 6, mixing pit 7 and pH probe 8, and submerged pump 2 is arranged on 3 the insides, medicine pond, grug transportation tube 1 one ends are connected to submerged pump 2 outlets, and the other end connects to mixing pit 7; Liquid in medicine pond 3 can be drawn in mixing pit 7 by submerged pump 2.At first external power source is connected to frequency converter 4, and then is connected to submerged pump 2, changes the rotating speed of submerged pump 2 by the frequency that changes frequency converter 4, and frequency converter 4 is connected on PLC5 by signal wire; PH probe 8 is arranged in mixing pit 7, and pH probe 8 is connected on transmitter 6 by signal wire, and transmitter 6 output terminals are connected on PLC5 by signal wire, and transmitter 6 plays the effect that signal transmits.PH probe 8 measured numerical value are processed by PLC5 and are then provided the output frequency that an output valve is controlled frequency converter 4.
For example, when the antacid liquid of needs, the 3 li dresses in medicine pond be akaline liquid, in one of given PLC5 and numerical value, pH probe 8 detects the acid degree in mixing pit 7, then by transmitter 6, numerical value is fed back to PLC5 and processes, when acid numerical value higher than in given and during numerical value, PLC5 controls frequency converter 4 work, thus drive submerged pump 2 from the medicine pond 3 li extract a certain amount of akaline liquid and neutralize with acidic liquid in mixing pit 7.
The PLC5 model is the Q00J of Mitsubishi, and pH probe 8 models are SY99-GP-PPS-GW.
the utility model using method, whole device is installed, switch on power, decided the size of the potential of hydrogen of this maintenance in current production according to the actual conditions in production run by the operator, to PLC5 input numerical value, pH probe 8 data that gather are sent on PLC5 by transmitter 6, in PLC5, pH set-point and pH actual measured value are compared, processing by intelligent PID algorithm and FUZZY ALGORITHMS FOR CONTROL, provide an output valve, control the output frequency of frequency converter 4, the size of frequency converter 4 frequencies has determined the rotating speed of submerged pump 2, thereby regulate the size of pH value.
