Background technology
Along with reinforcement, the hydraulic technique of Coal Mining Technology reaches its maturity, the large number quipments in colliery has adopted hydraulic technique, and in order to realize environmental protection, a lot of equipment adopt the emulsion hybrid technologies to replace hydraulic oil.Existing concentration of emulsion used proportion technique mainly adopts Artificial Control or fluidics, and distributing precision is low, does not reach the concentration that the colliery requires, and can cause simultaneously the damage to proportioning equipment, reduces the service life of proportioning equipment.For above-mentioned reasons, cause these existing proportion techniques under coal mine, not to be fully used.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of automatic proportioning system for coal mine emulsion pump station, and this system's emulsification distributing precision is high, and the emulsion of allotting can reach the concentration that coal mine equipment requires, simultaneously, reliable and stable, the long service life of matching system.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automatic proportioning system for coal mine emulsion pump station, comprise the centrifugal pump magnetic valve, water supply electromagnetic valve and PLC system, also comprise emulsion box, upper liquid-level switch, lower liquid-level switch, centrifugal pump and measuring pump, emulsion box is connected by tube connector with feed liquid pipeline, and the tube connector installation site is below lower liquid-level switch, upper liquid-level switch is arranged on the top of emulsion box inside, be connected with the PLC system signal of telecommunication, lower liquid-level switch is arranged on the below of emulsion box inside, be connected with the PLC system signal of telecommunication, centrifugal pump is arranged on the feed liquid pipeline in centrifugal pump magnetic valve downstream, be connected with the PLC system signal of telecommunication, measuring pump is arranged on the oil supply pipe.
The beneficial effects of the utility model are: this system is by the accurate fluid injection concentration of measuring pump, emulsion reached meet the concentration of coal mine equipment requirement; Receive up and down level switch signal and control magnetic valve by the PLC system simultaneously, make whole system form a closed-system, and oil temperature, the oil pressure of work pumping plant, the operational factor of motor read and arbitration functions, make demonstration and warning at display screen, thereby guaranteed the reliability of equipment, improved the service life of equipment, this proportion technique can be fully used under coal mine.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, emulsion box, 2, upper liquid-level switch, 3, lower liquid-level switch, 4, centrifugal pump, 5, the centrifugal pump magnetic valve, 6, measuring pump, 7, water supply electromagnetic valve, 8, the PLC system, 9, feed liquid pipeline, 10, tube connector.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, this automatic proportioning system for coal mine emulsion pump station comprises centrifugal pump magnetic valve 5, water supply electromagnetic valve 7 and PLC system 8, also comprises emulsion box 1, upper liquid-level switch 2, lower liquid-level switch 3, centrifugal pump 4 and measuring pump 6.Emulsion box 1 is connected by tube connector 10 with feed liquid pipeline 9, and the installation site of tube connector 10 is below lower liquid-level switch 3; Upper liquid-level switch 2 is arranged on the top of emulsion box 1 inside, is connected with PLC system 8 signals of telecommunication; Lower liquid-level switch 3 is arranged on the below of emulsion box 1 inside, is connected with PLC system 8 signals of telecommunication; Liquid-level switch can adopt the float inductive switch, and preferred ultrasonic type liquid-level switch can be installed on the outer wall of emulsion box 1, avoids because the impact that the extraneous factors such as the pressure in the emulsion box 1, temperature cause; Centrifugal pump 4 is arranged on the feed liquid pipeline in centrifugal pump magnetic valve 5 downstreams; Measuring pump 6 is arranged on the oil supply pipe.The utility model adopts plunger type metering pump, because the plunger type metering pump metering accurately, distributing precision is high.
At work, when lower liquid-level switch 3 did not all move, expression emulsion box 1 be empty, and at this moment, PLC system 8 sends instruction, and control water supply electromagnetic valve 7 injects clear water, and measuring pump 6 is worked and pressed the injection oil emulsion accurate in scale of 3%--5% simultaneously; During 2 action of upper liquid-level switch, show that emulsion box 1 filled with, PLC system 8 sends instruction, and control water supply electromagnetic valve 7 is closed, and controls simultaneously centrifugal pump magnetic valve 5 and centrifugal pump 4 is opened, and the emulsion in the case is injected work station; After emulsion is pumped fully, reenter circulation.But the measuring pump 6 signalization reponse systems in the system such as decoder, are connected with PLC telecommunications, realize remote monitoring.
This system is by the accurate fluid injection concentration of measuring pump, emulsion reached meet the concentration of coal mine equipment requirement; Receive up and down level switch signal and control magnetic valve by the PLC system simultaneously, make whole system form a closed-system, and oil temperature, the oil pressure of work pumping plant, the operational factor of motor read and arbitration functions, make demonstration and warning at display screen, thereby guaranteed the reliability of equipment, improved the service life of equipment, this proportion technique can be fully used under coal mine.
