Below in conjunction with the course of work of the even close agitating device of accompanying drawing analytic explanation above-mentioned band large-scale metal ore pulp.
Fig. 2 is control principle drawing of the present utility model.Composition graphs 2, Fig. 3 are known, and control section of the present utility model is controlled and concentration opened loop control three part by the action of liquid level opened loop control magnetic valve, speed closed loop.PLC circuit interconnect pattern of the present utility model as shown in Figure 3.
Starting agitating device can by Artificial Control, and when pressing switch S B1, KM coil obtains electric, and frequency converter and motor access three AC powers, and agitating device starts; Also can add ore pulp directly in device, when liquid level arrives lower liquid-level switch, lower liquid-level switch action, agitating device starts.
After device starts, PC-6D concentration measuring apparatus gathers pulp density analog signals (voltage signal), encoder gathers motor speed analog signals (voltage signal), these two signals are input in PLC by PLC analog input end, after PLC controls, analog output result is input to in frequency converter, frequency converter performs PLC Output rusults, sectional-regulated motor speed.Represented with U by magnitude of voltage corresponding to minimum running ore thickness up to standard, the motor speed that setting concentration U is corresponding is expressed as v1, sets a high-power speed of agitator v2(v2 in addition and is greater than v1).Boosting velocity procedure is: when the magnitude of voltage that PC-6D concentration measuring apparatus exports is less than setting value U, illustrate that concentration does not reach discharge quality requirement yet, the speed v that encoder imports into and v1 compare, if motor now rotating speed v is less than v1, the output speed of motor is changed into v1, if v is more than or equal to v1 but be less than v2, then motor speed adjusts the output to v2, if motor speed v is greater than v2, continues to keep output speed v, circulate this process, will ensure the output concentration of ore pulp.Down speeding procedure is: when the magnitude of voltage that PC-6D concentration measuring apparatus exports is greater than or equal to U, illustrate that concentration has reached discharge quality requirement, the same speed v imported into by encoder is carried out segmentation with v2 and is compared, if v is greater than v2, then by PLC and frequency converter, motor speed is reduced to v2, if v is less than v2 but be greater than v1, then by PLC and frequency converter, motor speed is reduced to v1, continue to keep exporting v1 rotating speed constant, when concentration is reduced under U again, recirculation boosting velocity procedure.According to the change of pulp density, persistent loop said process, both ensures that ore pulp exports concentration, object relatively energy-conservation again to reach.
When frequency converter breaks down, the switch motion that IO.2 connects, KM coil losing electricity, indicator lamp display frequency converter breaks down, and frequency converter disconnects with the KM switch of connecting in three AC powers, and frequency converter dead electricity, plays safeguard protection effect.
When mineral syrup liquid is higher than discharging opening height, then go up liquid-level switch action, upper liquid-level switch, from the IO.3 port reconfiguration of PLC to IO.4 port, exports to charging servo valve and discharging servo valve by QO.3 and QO.4.Control charging servo valve and reduce flow area, control discharging servo valve and increase flow area, to reduce liquid level, when liquid level is reduced to below upper liquid-level switch, upper liquid-level switch accesses the IO.3 port of PLC again, and charging servo valve and discharging servo valve return to original flow area.
