Description
Technical field
The utility model relates to and a kind ofly puts out the control device that automatic water supplement is carried out in the water seal of stove furnace roof to dried, belongs to the automatic control equipment technical field.
Background technology
In dry coke quenching is produced, driedly put out the water seal of stove furnace roof and adopt the main feedpump non-stop run, for feeding water in the furnace roof water sealed tank, under the normal circumstances,, form in the water seal water circulation and supply with because the Overflow drainage mouth is arranged at water sealed tank top.But find that in real work when main feedpump broke down, the man-hour Chang Wufa of patrolling and examining in daily the patrolling and examining found that in the very first time cause auxiliary feed water pump in time not to be activated, water sealed tank is had a strong impact on the dry coke quenching ordinary production because of lack of water burns out.Therefore, be necessary the existing dried stove furnace roof water seal arrangement that puts out is improved.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly, can start auxiliary feed water pump automatically and feed water when putting out stove furnace roof water seal main feedpump and breaking down dried, avoids the dried stove furnace roof water seal control device that puts out that has an accident.
The technical scheme that solves the problems of the technologies described above is:
A kind of dried stove furnace roof water seal control device that puts out, it comprises standby motor, auxiliary feed water pump, also comprise photoelectric level transducer GDY, relay K 1, contactor KM, switch power supply T1, start button SB1, stop button SB2, the sampling end of photoelectric level transducer GDY is installed in the water sealed tank, the signal output part of photoelectric level transducer GDY respectively with switch power supply T1, relay K 1 is connected, start button SB1, stop button SB2 becomes series circuit with the coil assembly of contactor KM, the main contact KM-3 of contactor KM in the master loop of motor, the normally closed interlock K1-1 of relay K 1, contactor KM often to open auxiliary contact KM-1 in parallel with start button SB1.
The above-mentioned dried stove furnace roof water seal control device that puts out, it also has alarm release knob SB3, combined aural and visual alarm DL, and the series circuit of forming with start button SB1, stop button SB2, the coil of contactor KM after auxiliary contact KM-2, the combined aural and visual alarm DL series connection of often opening of alarm release knob SB3, contactor KM is in parallel.
The above-mentioned dried stove furnace roof water seal control device that puts out also is equipped with air switch QF and thermo-relay KH in the master loop of standby motor.
Adopt this dried stove furnace roof water seal control device that puts out, when the water level in the water sealed tank drops to desired location, photoelectric level transducer GDY sends signal, relay K 1 coil losing electricity, normally closed interlock K1-1 closure, the coil of contactor KM is got, main contact KM-3 closure starts auxiliary feed water pump and supplies water in water sealed tank, can not influence the normal feedwater of water sealed tank, simultaneously can handle the main feedpump fault rapidly, the dried stove water seal water charging system that puts out is stablized.The utility model is simple and practical, makes easily, and result of use is good.
Description of drawings
Fig. 1 is an electrical schematic diagram of the present utility model.
Mark is as follows among the figure: photoelectric level transducer GDY, switch power supply T1, relay K 1, contactor KM, start button SB1, stop button SB2, alarm release knob SB3, combined aural and visual alarm DL, air switch QF, thermo-relay KH, insurance FU.
Embodiment
Show among the figure that the utility model is made up of parts such as photoelectric level transducer GDY, switch power supply T1, relay K 1, contactor KM, start button SB1, stop button SB2, alarm release knob SB3, combined aural and visual alarm DL, air switch QF, thermo-relay KH, insurance FU.
Show among the figure that the sampling end of photoelectric level transducer GDY is installed in the water sealed tank, when water level changed in the water sealed tank, photoelectric level transducer GDY sent electrical signal.The signal output part of photoelectric level transducer GDY is connected with switch power supply T1, relay K 1, and wherein two signal ends connect the positive and negative two ends of switch power supply T1, the coil of another signal relay termination K1 respectively.
Show among the figure, the coil assembly of start button SB1, stop button SB2, contactor KM becomes series circuit, the main contact KM-3 of contactor KM in the master loop of motor, the normally closed interlock K1-1 of relay K 1, contactor KM often to open auxiliary contact KM-1 in parallel with start button SB1.Often run auxiliary contact KM-2, the combined aural and visual alarm DL of alarm release knob SB3, contactor KM form another distance series circuit, and the series circuit that the coil of this series circuit and start button SB1, stop button SB2, contactor KM is formed is in parallel.
Show among the figure, air switch QF and thermo-relay KH also are installed in the master loop of standby motor, and diode pair relay K 1 is set on pilot circuit plays a protective role.For standby motor can be started at the scene, on pilot circuit, design start button SB1 simultaneously, can manually boot standby motor.
Since in the water sealed tank water temperature up to 60 degrees centigrade about, so an embodiment of the present utility model selects the high temperature resistant heat resistant type photoelectric level transducer GDY-210 that reaches 125 degrees centigrade for use.Because it is 12V that photoelectric level transducer GDY-210 requires power supply, therefore select the power supply of 220VAC/12VDC switch power supply T1 for use as transmitter, contactor KM is the 220VAC contactor, relay K 1 is the 12VDC rly..
Working process of the present utility model is as follows:
The utility model utilizes photoelectric level transducer conductivity principle in liquid, when liquid level is lower than photoelectric level transducer GDY, photoelectric level transducer GDY outage, the coil blackout of while relay K 1, the normally closed interlock K1-1 closure of outage back rly. K1, it is electric that the coil of contactor KM is got, the main contact KM-3 closure of contactor KM, and stand-by pump starts moisturizing in water sealed tank.Simultaneously, combined aural and visual alarm DL reports to the police to Central Control Room.After liquid level raise, photoelectric level transducer GDY switched on once more.Though relay K 1 contact K1-1 disconnects and since contactor KM often to open auxiliary contact KM-1 still closed, so stand-by pump can not stop to feed water.
After the Central Control Room personnel find that main feedpump does not supply water, can utilize alarm release knob SB3 to remove earlier and report to the police, notify the serviceman to handle then.After the serviceman fixes main feedpump, press stand-by pump stop button SB2,, restart main feedpump the stand-by pump outage.For stand-by pump can be started at the scene, on pilot circuit, designed start button SB1, can manually boot stand-by pump.
