Abstract
The utility model relates to an automatic chemical feeding device applied to sewage treatment, which belongs to the field of sewage treatment equipment, comprises a sewage treatment pond and is characterized by further comprising a chemical storage tank, a programmable logic controller (PLC), a touch screen, a frequency changer and a potential of hydrogen (pH) meter. The chemical storage tank is connected with a chemical feeding pump, a liquid level sensor is disposed in the chemical feeding pump and connected with the PLC, and the chemical feeding pump is connected with the sewage treatment pond through a chemical feeding pipeline. The pH meter is disposed in the sewage treatment pond to be connected with the PLC, and the touch screen is connected with the PLC which is further connected with the chemical feeding pump through the frequency changer. The automatic chemical feeding device applied to sewage treatment sets the pH value to be controlled through the touch screen, performs real-time automatic monitoring, and controls conditions of adding chemicals in the chemical storage tank through the PLC, thereby overcoming the defects of adding chemicals manually to adjust the pH value in the prior art, being safe, reliable, high in automation degree and low in cost and having good application prospects.
Description
Technical field
The utility model relates to a kind of automatic medicine adding apparatus that is applied to WWT, belongs to the sewage disposal device field.
Background technology
In the sewage treatment process, biochemical treatment is relatively stricter to the requirement of pH value, and general requirement is controlled at about 7.5, so sewage needed to regulate pH value before getting into the biochemistry pool processing.Dosing adjusting pH value generally is to rely on manual operation in the WWT at present; Concrete quantity that adds medicament and adding speed is fully with operator's experience, in operating process, and operator's agent of rule of thumb offeing medicine; In case careless manipulation then can cause pH value to change, the value of departing from objectives.So require extreme care in the operating process, and need certain experience, otherwise be difficult to the control pH value in target zone.Entire operation process uncertain factor is many, and the time is long, if misoperation can have bigger influence to follow-up biochemical treatment effect, whole biochemical processing process is impacted.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of and can overcome above-mentioned defective, can monitor in real time pH value, and the convenient automatic medicine adding apparatus that is applied to WWT of regulating pH value.
The utility model solves the technical scheme that its technical problem adopted: the described automatic medicine adding apparatus that is applied to WWT; Comprise treatment tank, it is characterized in that: also comprise medicine storing pot, PLC unit, touch-screen, frequency transformer and PH meter, medicine storing pot connects dosing pump; And be provided with liquid level sensor in it; Liquid level sensor is connected with the PLC unit, and dosing pump connects treatment tank through drug feeding pipeline, and the PH meter is arranged on and connects the PLC unit in the treatment tank; Touch-screen connects the PLC unit, and the PLC unit also is connected with dosing pump through frequency transformer.
Said liquid level sensor connects combined aural and visual alarm through the PLC unit.Liquid level sensor is connected combined aural and visual alarm and is reported to the police the amount of prompting adjustment medicament when liquid level is too high or too low.
Described drug feeding pipeline is provided with back pressure valve.Back pressure valve is used for preventing medicament generation spontaneous imbibition phenomena.
The beneficial effect that the utility model had is: use simple, the pH value that will control through the touch-screen setting, monitoring and control the interpolation situation of the medicament in the medicine storing pot through the PLC unit automatically guarantees that pH value is in the rational numerical scope all the time in real time.Overcome the original artificial medicament adjusting pH value that adds and got shortcoming, safe and reliable, level of automation is high, and is with low cost, has a good application prospect.
Description of drawings
Fig. 1 is the utility model frame principle figure;
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, the described automatic medicine adding apparatus that is applied to WWT comprises treatment tank; It is characterized in that: also comprise medicine storing pot, PLC unit, touch-screen, frequency transformer and PH meter; Medicine storing pot connects dosing pump, and is provided with liquid level sensor in it, and liquid level sensor is connected with the PLC unit; Dosing pump connects treatment tank through drug feeding pipeline; The PH meter is arranged on and connects the PLC unit in the treatment tank, and touch-screen connects the PLC unit, and the PLC unit also is connected with dosing pump through frequency transformer.Liquid level sensor is connected with combined aural and visual alarm through the PLC unit.Liquid level sensor is connected combined aural and visual alarm and is reported to the police the amount of prompting adjustment medicament when liquid level is too high or too low.Drug feeding pipeline is provided with back pressure valve, and back pressure valve is used for preventing medicament generation spontaneous imbibition phenomena.Frequency transformer can be according to the signal of PLC, the rotating speed of adjustment dosing pump, and adjustment adds dose automatically.
During use, through the pH value that touch-screen need be controlled to the input of PLC unit, the PH meter transfers to the PLC unit with the signal of detected pH value, and the PLC unit can be counted detected pH value with PH again and come out through screen displaying, realizes monitoring in real time.The PLC unit compares the pH value of detected pH value and input; If depart from the pH value of setting; Then the PLC unit adds the medicament in the medicine storing pot in the treatment tank through Frequency Converter Control dosing pump rotating speed; Regulate the pH value of sewage, it is remained in the scope that needs always, guarantee the demand of subsequent treatment process.
