Abstract

The utility model relates to a coal heating device, which has a hearth, grates and a control part, wherein, the grates are arranged in the hearth; the control part uses a single-chip microcomputer as a core; the flame viewing port of the heart is provided with a photosensitive sensor; the coal entrance passage of the hearth is provided with a grate sensor; a hearth sensor is arranged in the hearth. Via A/D converters, signals of the photosensitive sensor, the grate sensor and the hearth sensor are respectively output to the single-chip microcomputer, which sends out commands to a motor and an air blower. The utility model can realize automatic control of coal combustion and has a wide adaptable range.

Description

A kind of coal-fired heater

Technical field

The utility model relates to a kind of heating plant, is specially a kind of coal-fired heater.

Background technology

At present, coal-fired heater mainly is made up of burner hearth and fire grate, and fire grate is located in the burner hearth, the propelling of fire grate is by manually observing, judge that combustion case decides by rule of thumb from seeing burner, perhaps push away coal with time relay control, its precision is not enough, and people's judgment is had relatively high expectations; In addition, because gap, chain turning is bigger, fall in this gap for preventing slag, often add baffledly herein, it is short that baffle plate continues to be subjected to high temperature life, and hinder the normal operation of slag.

The utility model content

The purpose of this utility model is to provide a kind of automatic control coal-fired heater.

The technical solution of the utility model is:

A kind of coal-fired heater, have burner hearth, fire grate, control section, establish fire grate in the burner hearth, control section is core with the single-chip microcomputer, the sight jet-burner of burner hearth is provided with light sensor, the coal channel place of advancing of burner hearth is provided with the fire grate sensor, be provided with the burner hearth sensor in the burner hearth, the signal that light sensor, fire grate sensor, burner hearth sensor provide exports single-chip microcomputer to through A/D converter respectively, wherein the photosignal that provides of light sensor is exported with digital form through A/D converter, send instruction by single-chip microcomputer and give motor, push away coal; The temperature signal that the fire grate sensor provides is exported with digital form through A/D converter, sends instruction by single-chip microcomputer and gives motor, pushes away coal; The temperature signal that the burner hearth sensor provides is exported with digital form through A/D converter, sends instruction by single-chip microcomputer and gives air blast, carries out air blast.

Dull and stereotyped both sides on the fire grate joint stretch out, and the one side is extended along plane on the flat board, and opposite side extends along dull and stereotyped lower plane, stack into the plane mutually between the flat board of adjacent fire grate joint.

The beneficial effects of the utility model are:

1. realize the automatic control of fired coal combustion.The utility model control section is core with the single-chip microcomputer, the sight jet-burner of burner hearth is provided with light sensor, the coal channel place of advancing of burner hearth is provided with the fire grate sensor, be provided with the burner hearth sensor in the burner hearth, the signal that light sensor, fire grate sensor, burner hearth sensor provide exports single-chip microcomputer to through A/D converter respectively, thereby has realized pushing away automatically control automatically such as coal and air blast.

2. the utility model is applicable to boiler heat supplying, heating, also is applicable to the device that hot blast is provided for winter booth vegetable, flower planting, domestic birds and animals raising etc.

The specific embodiment

Embodiment

Shown in Fig. 1～3, a kind of coal-fired heater of the utility model, have burner hearth, fire grate, control section, establish fire grate in the burner hearth, control section is core with the single-chip microcomputer, sight burner 11 places on the fire door 18 are provided with light sensor 12, coal channel 17 places of advancing of burner hearth 1 are provided with fire grate sensor 14, are thermocouple, and burner hearth 1 top is provided with burner hearth sensor 15, be thermocouple, the signal that light sensor 12, fire grate sensor 14, burner hearth sensor 15 provide exports single-chip microcomputer to through A/D converter respectively; Flat board 161 both sides on the fire grate joint 16 stretch out, and the one side is extended along plane on the flat board, and opposite side extends along dull and stereotyped lower plane, stack into the plane mutually between the flat board of adjacent fire grate joint, and slag stopped up chain when this structure prevented to turn effectively; Light sensor 12 is photo resistance (CDS), is selected from Seoul, South Korea electronics firm.

The photosignal that the utility model light sensor 12 provides is exported with digital form through A/D converter, sends instruction by single-chip microcomputer and gives motor 4, and it can replace the manual observation combustion case, judge according to combustion case, finish pushing away coal, save manpower, realize control automatically; The temperature signal that fire grate sensor 14 provides is exported with digital form through A/D converter, malfunctioning or device quits work and protects fire when (keeping fire not go out) when light sensor 12, fire grate 13 does not advance, this moment, fire coal burnt away, as burnt to coal bunker 3, serious consequence can occur, and after fire grate sensor 14 is installed, when fire grate sensor 14 detects uniform temperature, report to the police, send instruction by single-chip microcomputer and give motor 4, finish pushing away coal; The temperature signal that burner hearth sensor 15 provides is exported with digital form through A/D converter, cause the burner hearth burning insufficient if the coal amount is not enough or ature of coal is bad, when burner hearth sensor 15 detects the burner hearth uniform temperature, send instruction by single-chip microcomputer and give air blast 2, start air blast 2 and add wind for bellows 21, be coal-fired combustion-supporting.

The course of work of the present utility model is: fire coal is sent into burner hearth 1 from coal bunker 3, bellows 21 place fire grate 13 bottoms, air blast 2 combustion-supporting down, make coal-fired fully burning, push away coal by light sensor 12 controls, it pushes away coal operation: starter motor 4, power successively through eccentric wheel 43, connecting rod 42, worm screw 41, worm gear 45, sprocket wheel 44 to fire grate 13, finish aforesaid operations by Single-chip Controlling.
