Fig. 1 is the utility model structural representation;
Wherein 1, molten explosive barrel, 2, liquidometer, 3, agitator, 4, surge pump, 5, snubber assembly, 6, back pressure regulating valve, 7, valve, 8, magnetic valve, 9, under meter, 10, chemical feeding points joint.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of mechanical constant pressure type multiple spot stable state chemicals dosing plant, comprise and hold the molten explosive barrel 1 of medicament, the drug feeding pipeline of surge pump 4, back pressure regulating valve 6, snubber assembly 5 and a plurality of parallel connections of conveying liquid, on the export pipeline of molten explosive barrel 1, be arranged in parallel surge pump 4 and back pressure regulating valve 6, surge pump 4 exit end are connected with the drug feeding pipeline of snubber assembly 5, back pressure regulating valve 6 and a plurality of parallel connections successively.
Pipeline between molten explosive barrel 1 and surge pump 4 is provided with the valve of controlling surge pump 4 and back pressure regulating valve 6, for controlling this chemicals dosing plant medicinal liquid flow.
On the throughput direction of liquid, a plurality of drug feeding pipeline are all disposed with valve 7, magnetic valve 8, under meter 9 and chemical feeding points joint 10.
The agitator 3 that stirs medicament and the liquidometer 2 that shows molten explosive barrel 1 interior pharmaceutical quantities are installed in molten explosive barrel 1, liquidometer 2 can be selected according to actual demands of engineering, as long as can transmission signal, agitator 3 can not stop to stir to medicament, and liquidometer 2 can accurately show a barrel interior pharmaceutical quantities in real time.
In back pressure regulating valve 6, be provided with spring and diaphragm, when system pressure changes, diaphragm coordinates with spring, realizes drug feeding pipeline constant pressure.Snubber assembly 5 is pulse damper, and principle of work is: at the discharge stroke of pump, in pulse buffer, gas is compressed, and the amount of liquid in pulse buffer increases, and this part of liquid of just pump being discharged has deposited pulse buffer in, has cut down peak flow; In the intake stroke of pump, air expansion in pulse buffer, in pulse buffer, liquid flows out, and supplements piping flow, increases piping flow valley, thereby has reduced the flow pulsation of pipeline.Snubber assembly 5 is followed Boyle law: under steady temperature, the absolute pressure of a certain amount of gas and volume are inversely proportional to: P1 * V1=P2 * V2, the pulsation of the level and smooth pipeline of change by gas volume, especially for flow velocity, there is the system of sinusoidal curve characteristic, when crest, air chamber smaller volume, snubber assembly 5 absorbs the liquid of unnecessary flow; When trough, it is large that air chamber volume becomes, and snubber assembly 5 can discharge the liquid of storage, thereby reaches level and smooth pulsation and system water hammer, realizes the constant of drug feeding pipeline pressure, without variable frequency control.
Back pressure regulating valve 6 is combined with snubber assembly 5 while using, and the peak flow of controlling between absorbing septum pump 4 and back pressure regulating valve 6 by snubber assembly 5, realizes the constant of drug feeding pipeline pressure, without variable frequency control; In addition, can prevent that back pressure regulating valve 6 is along with the stroke of surge pump 4 opens and closes fast, thereby effectively reduce the rate of wear of back pressure regulating valve 6.
Pipeline is UPVC pipe, and surge pump 4, snubber assembly 5, back pressure regulating valve 6, valve 7, magnetic valve 8 and under meter 9 are fixed on base, and the implementation of this device is flexible, can coordinate engineering to carry out multiple spot installation, also can complete installation, and as integration apparatus.
Working process:
The a certain amount of medicament that needs conveying of the interior injection of molten explosive barrel 1,3 pairs of medicaments of agitator in molten explosive barrel 1 stir fully, after medicament is mixed, medicament is by the supercharging of surge pump 4, enter into dosing main pipeline, and by the cooperation of snubber assembly 5 and back pressure regulating valve 6, control the pulsation peak value that regulates surge pump 4 to produce, the water hammer of the pipeline smoothly being caused by surge pump 4 isometric(al) pumps pulsation and system.
Before work, debug and set the force value of back pressure regulating valve 6, when drug feeding pipeline switch causes fluctuations in discharge, system pressure also changes thereupon.When system pressure is less than setting pressure, diaphragm is blocking pipeline under spring force effect; When system pressure is greater than setting pressure, diaphragm compression spring is connected pipeline, and liquid be back to the entrance end of surge pump 4 by back pressure regulating valve 6, realize drug feeding pipeline constant pressure, and the pressure of each root drug feeding pipeline all equates, without variable frequency control.In every drug feeding pipeline, be equipped with valve 7, magnetic valve 8 and the under meter 9 of controlling each pipeline medicinal liquid flow, by-pass valve control 7 regulates the chemical feeding quantity of each pipeline, and PLC controls magnetic valve 8 switches, can realize automatization and control each chemical feeding points dosing process.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
