Accompanying drawing explanation
Fig. 1 ~ 2 become annealing furnace glass to pass in and out stove delay alarming device control circuit electrical schematic diagram for figure.
Embodiment
Fig. 1 ~ 2 are most preferred embodiments of the present utility model, are described further below in conjunction with accompanying drawing 1 ~ 2 pair of the utility model.
Figure becomes annealing furnace glass to pass in and out stove delay alarming device, comprises and is arranged on the infrared temperature measurement apparatus that figure becomes annealing furnace body of heater exit, and infrared temperature measurement apparatus change send output port to connect a secondary instrument, and arranges corresponding upper temperature limit by this secondary instrument.Secondary instrument receive infrared temperature measurement apparatus send with temperature value 4 ~ 20mA signal one to one, after the temperature value corresponding to the current signal that secondary instrument receives reaches the upper temperature limit of setting, the actuating of relay that secondary instrument is built-in.Annealing furnace glass is become to pass in and out in stove delay alarming device, by the normally opened contact Access Control circuit of secondary instrument repeat circuit at this figure.
In the control circuit electrical schematic diagram shown in Fig. 1 ~ 2, comprise direct current 24V control circuit and alternating current 220V control circuit two parts.In direct current 24V control circuit, 24V positive pole is one end of the coil of relay K A1 in parallel ~ KA2 simultaneously after tandem tap QF1 and normally opened contact KA5-1 successively, the other end 24V negative pole in parallel simultaneously of the coil of relay K A1 ~ KA2.The normally opened contact of normally opened contact KA5-1 and above-mentioned secondary instrument repeat circuit.
In alternating current 220V feed circuit, with simultaneously following loop in parallel between zero line N after live wire L tandem tap QF2:
The loop that the while of between pushbutton switch SA1 and the coil of time relay KT1, the normally opened contact KA1-1 of relay K the A1 in parallel and normally opened contact KA2-1 of relay K A2 forms;
The loop that the while of between pushbutton switch SA2 and the coil of time relay KT2, the normally closed contact KA1-2 of relay K the A1 in parallel and normally closed contact KA2-2 of relay K A2 forms;
The loop of the coil composition of the normally opened contact KT1-1 series relay KA3 of time relay KT1;
The loop of the coil composition of the normally opened contact KT2-1 series relay KA4 of time relay KT2;
The loop of the coil composition of normally opened contact KA3-1 ~ KA4-1 series contactor KM1 of relay K A3 parallel with one another ~ KA4;
Contactor KM1-1 connects the loop of following circuit composition: pushbutton switch SA3 to connect after electric bell DL1 alarm lamp DL2 in parallel again.
Specific works process and principle of work as follows:
Glass becomes the temperature of coming out of the stove in annealing furnace higher at figure, be about 580 DEG C, when arranging the upper temperature limit of secondary instrument, can arrange far away higher than normal temperature lower than the temperature spot of glass own temperature, as 300 DEG C, enter figure become the glass in annealing furnace all can be detected to ensure to have more.Before glass enters, pushbutton switch SA1 ~ SA3 is closed.
Annealing furnace is become and after reaching exit smoothly when first block of glass enters figure, corresponding current signal is sent into secondary instrument after glass being detected by infrared thermometer, after secondary instrument judges to have reached the upper temperature limit of himself, confirm as glass and reach outlet, the actuating of relay in it, normally opened contact KA5-1 closes, and the coil of relay K A1 ~ KA2 is powered on action.
Normally opened contact KA1-1 ~ the KA2-1 of relay K A1 ~ KA2 closes, and normally closed contact KA1-2 ~ KA2-2 disconnects.Time relay KT1 connected after normally opened contact KA1-1 ~ KA2-1 is closed simultaneously and start timing.And after reaching the time of time relay KT1 setting, show that this block glass is not smooth to export from fire door, now time relay KT1 action, normally opened contact KT1-1 closes and the coil of relay K A3 is powered on action, and normally opened contact KA3-1 closes and the coil of contactor KM1 is powered on action.Normally opened contact KM1-1 is closed to be connected electric bell DL1 and alarm lamp DL2, carries out sound and light alarm.
After glass is smoothly by outlet, the temperature in source reduces, time under the upper temperature limit being reduced to secondary instrument, normally opened contact KA5-1 disconnects, cut off by the current supply circuit of the coil of relay K A1 ~ KA2, normally opened contact KA1-1 ~ KA2-1 disconnects simultaneously, and normally closed contact KA1-2 ~ KA2-2 closes.Time relay KT2 connected after normally closed contact KA1-2 ~ KA2-2 is closed simultaneously and start timing.
When second block of glass reaches body of heater outlet smoothly, normally opened contact KA5-1 closes, and the course of work is same as described above.If after reaching the setting-up time of time relay KT2, represent that second block of glass does not arrive fire door place smoothly, then now normally opened contact KT2-1 closes, and the coil of relay K A4 powers on action, and normally opened contact KA4-1 closes and the coil of contactor KM1 is powered on action.Normally opened contact KM1-1 is closed to be connected electric bell DL1 and alarm lamp DL2, carries out sound and light alarm.
When according to do not do glass in the normal workflow short time or without glass time, button switch K A2 can be adjusted to off-state, to prevent long-time warning.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
