Abstract
The utility model relates to a burning safety controller for a burner. The utility model is characterized in that the utility model is composed of a power supply, a microcomputer, a flame detection circuit, an ignition control circuit, an oil valve control circuit, a driving fan motor circuit, an off-machine alarm circuit and an output relay; the flame detection circuit is formed by that a light sensitive tube is connected with a triode through a capacitance-resistance filter, and the flame detection circuit is connected with the input terminal of the microcomputer; signals output by microcomputer programs are shaped and amplified and then drive the corresponding relay to drive an ignition transformer, the oil valve control circuit, the driving fan motor circuit and the off-machine alarm circuit. The controller has the advantages of simple structure, small volume, high control precision, high anti-interference capability, and enhanced performance of safe control for burning.
Description
The utility model relates to a kind of burner combustion completion controller, and it is mainly used in the burner combustion control and the combustion completion control of burning boiler, burning kiln.
At present, burner uses mechanical combustion completion controller with combustion completion controller majority, as being to control by many groups reed contact to the unlatching of oil pump valve, igniting, flame monitoring etc., its complicated in mechanical structure, the heating of contact wearing and tearing, therefore, there are shortcomings such as the burning control accuracy is low, poor safety performance, manufacturing process complexity in mechanical combustion completion controller.
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of electronic type by micro-processor controlled burner combustion completion controller.
The technical solution of the utility model is: it is by power supply, microcomputer, flame detects, IGNITION CONTROL, fuel tap control, outer warning circuit of fan motor and machine and output relay are formed, detect photosensitive tube through resistance and capacitor filtering and the triode flame detection circuit that is formed by connecting by flame, its output is connected with the microcomputer input, according to the size of flame detection signal and the microcomputer output signal of setting program respectively through amplifying back promotion corresponding relays drive ignition transformer through separately triode again after the resistance capacitance shaping, fuel tap control, the outer relay of reporting to the police of fan motor and machine.
Because the utility model uses electronic type to be realized burning control and combustion completion control holding of burner by microcomputer, makes control accuracy be improved significantly.The high sensitivity of employing electronic device has improved this controller signals detection sensitivity also makes its security control performance be improved.This controller architecture is simple, and volume is little, is convenient to install and use.Large tracts of land ground connection is covered the Copper layer and radome constitutes electromagnetic shielding owing to the computer plate that is made of single chip microcomputer and control element is equipped with, and makes controller have very strong interference free performance.
The utility model embodiment is described further in conjunction with the accompanying drawings.
Fig. 1 is the utility model schematic circuit,
Fig. 2 is the utility model flow chart.
By shown in Figure 1, major function of the present utility model is finished by single chip microcomputer AT89C51 or AT89C2051, power unit is: input AC 220V voltage is through R1, C1 resistance-capacitance depressurization, obtain direct current 24V voltage and offer output relay work after the VC1 full-wave rectification, the 24V DC voltage becomes the 5V DC voltage to offer single-chip microcomputer work through three terminal regulator 7805 voltage stabilizings.Detect photosensitive tube through resistance R 11 by flame, R12 and capacitor C 13 filtering and the triode VT6 flame detection circuit that is formed by connecting, output is connected with the microcomputer input pin after its shaping, according to the size of flame detection signal and the microcomputer output signal of setting program respectively through resistance R 4-R7, after triode VT1-VT4 amplification separately, promote corresponding relays KA1-KA4 drive ignition transformer respectively after the capacitor C 9-C12 shaping again, the control of first order fuel tap, second level fuel tap control, fan motor and machine are reported to the police outward, diode V1-V4 is as the filtered diode of relay coil, resistance R 9 and capacitor C 6 are formed electrify restoration circuit and are offered power-on reset signal of single-chip microcomputer, and machine reset is finished by mini button SB1.The component of entire controller is distributed on two printed circuit board, wiring board discharge source portion of element and output relay, another piece wiring board constitutes the computer plate and puts single-chip microcomputer and control element, two wiring boards connect with a connector assembly, the computer plate is equipped with large-area ground connection Fu Copper layer and radome constitutes electromagnetic shielding, suppresses to disturb.
