Abstract
The utility model relates to an online frequency-conversion dosing system with closed-loop control, which comprises an electromagnetic flowmeter, a PLC (Programmable Logic Controller), a frequency converter, a dosing metering pump, a pipeline mixer and an online detector, wherein the output end of the electromagnetic flowmeter is connected to the online detector sequentially through the PLC, the frequency converter, the dosing metering pump and the pipeline mixer; an output port of the online detector is also connected with an input port of the PLC. The online frequency-conversion dosing system can be used for accurately measuring flow rate of a water body, adjusting the dosing amount in real time and ensuring safety and health of the water quality.
Description
Technical field
The utility model relates to the frequency conversion administration system, particularly relates to a kind of online frequency conversion administration system of closed-loop control.
Background technology
The administration device of drinking water disinfection systems such as tap water, mineral water part all is to use volume pump that the pipeline of water body is carried out quantitative chemical dosing or uses water sprayer to carry out the negative-pressure siphon dispensing at present; The flow of water body is not accurately measured; Can't make the variation of the corresponding discharge of chemicals feed pump and, the Herb of Common violet liquid hold-up after adding is not monitored change.And owing to water flow is not measured accurately, the dosage of chemicals feed pump causes the water flow in pipeline to change not to change; But the dosage of soup is still constant, and it is excessive just to cause sometimes soup to add easily, sometimes adds not enough; When adding when excessive, can cause soup residual, when adding not enough amount; It is clean to cause bacterium to kill, and can cause bacteria content to exceed standard, no matter which kind of result will influence the health of human body.
Summary of the invention
For avoiding the deficiency of above prior art, the utility model proposes a kind of online frequency conversion administration system of closed-loop control, with solve when offer medicine to water body can not be in real time accurately to pipeline in the problem that detects of water flow.
The purpose of the utility model realizes through following technical scheme:
The online frequency conversion administration system of closed-loop control; This system comprises magnetic flow meter, PLC unit, frequency transformer, dosing pump, line mixer and on-line detector; The output terminal of described magnetic flow meter is connected to on-line detector through PLC unit, frequency transformer, dosing pump, line mixer successively, and an output port of this on-line detector also is connected with an input port of said PLC unit.
Further, described on-line detector is online residual chlorine detecting instrument.
The advantage of the utility model is:
1. can accurately measure the flow of water body in the pipeline, make the dosage of chemicals feed pump according to the automatic corresponding adjustment of the variation of flow.
2. the utility model can also carry out on-line monitoring to the contents of residual chlorine in the water body in the pipeline; And adjust the dosage of chemicals feed pump once more according to monitoring result; Reach the online accurate frequency conversion dispensing of closed-loop control, make the amount of liquid medicine of water body keep constant, useful HUMAN HEALTH.
Description of drawings
Fig. 1: the theory structure synoptic diagram of the utility model.
Embodiment
Be illustrated in figure 1 as the online frequency conversion administration system theory structure synoptic diagram of the utility model closed-loop control.This system comprises magnetic flow meter, PLC unit, frequency transformer, dosing pump, line mixer and on-line detector; The output terminal of described magnetic flow meter is connected to on-line detector through PLC unit, frequency transformer, dosing pump, line mixer successively, and an output port of this on-line detector also is connected with an input port of said PLC unit.Described on-line detector is online residual chlorine detecting instrument.
The working process of above-mentioned this online frequency conversion administration system is described below.At first use magnetic flow meter that the water flow of pipeline is measured, this magnetic flow meter sends measuring result to the PLC unit then.The PLC unit sends wave according to the signal contrast result and gives frequency transformer, and frequency transformer cooperates with the dosing pump, thereby regulates the dosage of volume pump.Water body after soup adds is through line mixer; Make soup and water body reach thorough mixing; Certain distance behind line mixer carries out water body chlorine residue on-line monitoring, monitoring result input PLC unit, and unit sends signal once more according to the signal contrast result and gives frequency transformer; Once more the dosage of dosing pump is revised, thereby obtained a closed loop, administration system accurate, that monitor in real time.This administration system of the utility model can carry out accurate strategy to water flow, adjusts dosage in real time, has guaranteed the safety and Health of water quality.
Claims (2)
1. the online frequency conversion administration system of closed-loop control; It is characterized in that; This system comprises magnetic flow meter, PLC unit, frequency transformer, dosing pump, line mixer and on-line detector; The output terminal of described magnetic flow meter is connected to on-line detector through PLC unit, frequency transformer, dosing pump, line mixer successively, and an output port of this on-line detector also is connected with an input port of said PLC unit.
2. the online frequency conversion administration system of closed-loop control according to claim 1 is characterized in that, described on-line detector is online residual chlorine detecting instrument.
