Description

The alert circuit that a kind of boiler uses

Technical field

The utility model relates to the alert circuit that a kind of boiler uses.

Background technology

At present, in the production process of enterprise, many times be the steam of the shared boiler of a plurality of agitated reactors; But the use of the steam of each agitated reactor is different with the heating-up time, like this, if blindly give the gas lift temperature; The steam pressure of boiler can be not enough, and influence is produced, and sometimes all under the situation without gas; Boiler but still at heat temperature raising, causes waste.

Summary of the invention

The purpose of the utility model provides neither influence and produces, the alert circuit of again can wasting a kind of boiler not using.

The technical scheme that the utility model is taked is: the alert circuit that a kind of boiler uses, it is characterized in that between phase line of power and zero line, parallel connection some group-indicate lamp control circuits and a time relay circuit; Comprise normally closed cooling press button one, the intensification press button of often opening, intensification indicator lamp, cooling indicator lamp and relay in every group-indicate lamp control circuit; Cooling press button one, intensification indicator lamp and an end of cooling indicator lamp are connected phase line; The other end of cooling press button one is connected with intensification press button one, relay coil successively; Relay coil connects zero line, and a normally opened contact of intensification press button one and relay is in parallel; The intensification indicator lamp is connected in series with another normally opened contact of relay mutually, and the cooling indicator lamp is connected in series with the normally-closed contact of relay mutually, and another normally opened contact of relay is connected zero line with normally-closed contact;

In time relay circuit, comprise the electric bell and the time relay, and with every group-indicate lamp control circuit to intensification press button of often opening two and the cooling press button of often opening two should be arranged; One end of the normally opened contact of intensification press button two, cooling press button two, the time relay and the time-delay normally opened contact of the time relay is connected phase line; After being associated, the normally opened contact of intensification press button two, cooling press button two and the time relay is connected in series the time-delay normally-closed contact of time relay coil, the time relay successively; The time-delay normally opened contact serial connection electric bell of the time relay, the time-delay normally-closed contact of the time relay is connected with zero line with electric bell.

Adopt the utility model, can be with the corresponding one by one agitated reactor of some group-indicate lamp control circuits, and be installed in the boiler position to indicator lamp in the circuit and electric bell; Remaining is installed in the control room; Through press button control indicator lamp and electric bell, the heat temperature raising of boiler is carried out in prompting then, reaches a boiler and supplies a plurality of agitated reactors to use; And do not influence production, again can wasting purpose.

Description of drawings

Fig. 1 is the sketch map that has two group-indicate lamp control circuits in the utility model.

The specific embodiment

Be described further in the face of the utility model down.

With reference to Fig. 1, on the phase line of power A and zero line N of the alert circuit that this boiler uses, parallelly connected two group-indicate lamp control circuits and a time relay circuit; Comprise normally closed cooling press button SA1, the intensification press button SA2 that often opens, intensification indicator lamp L1, cooling indicator lamp L2 and relay J 1 in every group-indicate lamp control circuit; Cooling press button SA1, intensification indicator lamp L1 and the end of cooling indicator lamp L2 are connected phase line A; The other end of cooling press button SA1 is connected with the coil of intensification press button SA2, relay J 1 successively; The coil of relay J 1 connects zero line N, and a normally opened contact J1-1 of intensification press button SA2 and relay J 1 is in parallel; Intensification indicator lamp L1 is connected in series with another normally opened contact J1-2 of relay J 1 mutually, and cooling indicator lamp L2 is connected in series with the normally-closed contact J1-3 of relay J 2 mutually, and another normally opened contact J1-2 of relay J 1 is connected zero line with normally-closed contact J1-3;

In time relay circuit, comprise electric bell HA and time relay JS, and with every group-indicate lamp control circuit to the intensification press button SA3 that often opens and the cooling press button SA4 of Chang Kai should be arranged; The end of the normally opened contact JS-1 of intensification press button SA3, cooling press button SA4, time relay JS and the time-delay normally opened contact JS-3 of the time relay is connected phase line A; After being associated, the normally opened contact JS-1 of intensification press button SA3, cooling press button SA4 and the time relay is connected in series the coil of time relay JS, the time-delay normally-closed contact JS-2 of time relay JS successively; The time-delay normally opened contact JS-3 serial connection electric bell HA of time relay JS, the time-delay normally-closed contact JS-2 of the time relay is connected with zero line N with electric bell HA.

Its operation principle and process are following: when certain agitated reactor need be heated, the operative employee of agitated reactor just pressed the normally open push button switch SA2 of intensification, and relay J 1 gets electronic work, normally opened contact J1-1 self-locking; At this moment, normally-closed contact J1-3 breaks off, and cooling indicator lamp L2 extinguishes, and normally opened contact J1-2 connects; The bright expression of intensification indicator lamp L1 lamp begins to heat up, and simultaneously, intensification press button SA3 connects, and time relay JS gets electronic work; Normally opened contact JS-1 self-locking, time-delay normally opened contact JS-3 connects, and electric bell HA sounds; Behind the time relay JS time-delay certain hour, time-delay normally opened contact JS-3 breaks off, and electric bell HA stops; At this moment, the tinkle of bells reminds the fireman of boiler room to start working, and bright through intensification indicator lamp L1 lamp, tells that clearly the boiler room fireman is that which platform agitated reactor needs to heat up; Because every agitated reactor needs the length of heating-up time, the boiler room fireman know in advance, at this moment, just can autotelic coal, need heat up one hour like this agitated reactor, so, only a need burning in boiler can stop coal in 40 minutes; When the service life of above mentioned agitated reactor to the time, the agitated reactor operative employee will be by normally closed push button switch SA1, relay J 1 dead electricity, normally opened contact J1-2 breaks off; Intensification indicator lamp L1 extinguishes, and normally-closed contact J1-3 connects, and cooling indicator lamp L2 lamp is bright; Simultaneously, normally open push button switch SA4 is closed, and time relay JS gets electronic work; Normally opened contact JS-1 self-locking, time-delay normally opened contact JS-3 connects, and electric bell HA sounds; Behind the time relay JS time-delay certain hour, time-delay normally opened contact JS-2 breaks off, and electric bell HA stops; The fireman of notice boiler room stops coal.

Equally; Connected mode, operation principle and the process of other one group indicator lamp control circuit is with above-mentioned the same; As long as the operative employee of agitated reactor and the fireman of boiler room carry out the corresponding agitated reactor and the operation of boiler room and get final product bright or extinguish according to which indicator lamp lamp.
