A display circuit which is controlled by a photoelectric head DU installed in the observation hole of the boiler door or the preheated boiler wall and is composed of a transformer T-[1], a bridge rectifier circuit VD-[1], a filter capacitor C-[1], a resistor R-[1] and a diode V-[1], a display circuit composed of a relay K-[1], a resistor R and diodes V-[2] and V-[3], and a monostable circuit composed of potentiometers RP-[1] and RP-[2], a voltage-stabilizing integrated block timing capacitor C-[2], a voltage dividing resistor R-[3], diodes V-[4] and V-[5] and a time base circuit board NE555 are arranged in the shell body of the controller.
Description
The utility model belongs to the boiler accessories class.
The boiler that existing reciprocating fire grate, chain furnace grate etc. are delivered coal automatically is by press button, relay, Electric Machine Control; Coal on the fire grate passes through preheating section from outside to inside successively, main combustion section, after-flame section; When the flame of main combustion section extended to preheating section, starter motor was delivered coal fire grate inwards immediately, and the coal on the preheating section fire grate can not be burnt; The coal combustion of late preheating section if delivered coal, boiler can not be obtained the thermal efficiency of expection, waste fuel; On the contrary, if deliver coal too early, the coal on the fire grate enters main combustion section and can not in time burn, and the coal of after-flame section can not after-flame, and bunker coal will be wasted very big, and the boiler thermal efficiency that can not obtain expecting equally.So delivering coal that boiler is in good time is very important, and existing delivering coal, be difficult to the degree that reaches in good time with operating personnel's observation entirely, institute's waste of fuel is bigger, and the thermal efficiency of boiler is low.
The purpose of this utility model is: provide a kind of, according to the combustion case in the boiler, can advance the coal controller automatically by boiler in good time, that deliver coal automatically; To reach the purpose of fuel saving and raising boiler thermal output.
Technical measures of the present utility model are: utilize a controller housing, attaching plug, switch, potentiometer RP are housed on the housing

4, the monostable circuit that forms of time base circuit plate NE555; Photometer head is being controlled again the deliver coal A.C. contactor of motor of boiler according to control of fire monostable circuit, the monostable circuit of boiler, makes it automatically in good time and delivers coal or stop to deliver coal.
The utility model, employing is by the photometer head of boiler intensity of a fire influence, photometer head is being controlled the monostable circuit of controlling in the housing, relay in this circuit, control the deliver coal interchange contact of motor of boiler again, make in good time the delivering coal or stop to deliver coal of boiler, this has fairly obvious good effect to fuel saving and thermal efficiency of improving boiler.
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a rearview, and Fig. 3 is a circuit diagram.
DU in the circuit diagram is the photometer head of a device in Boiler door peep hole place or boiler preheating section furnace wall, and it is by housing 5, phototriode V
