The course of work
1. the thermal cycle of mechanism
Coal-fired soil heating boiler heating is to rely on the realization of thermal cycle.Recirculated water enters furnace body water tank via water inlet 14
18, via helical heating pipe 16, heat primary heating is absorbed in a combustion chamber.Later, the water heated for the first time is via connection
Mouth enters flue water tank 20, continues to flow by flue heat exchange pipe 15, absorbs the amount of residual heat reheating of fuel draining flue gas.
The water that reheating is completed participates in heating circulation by caliduct.In thermal cycle, helical heating pipe 16 is primary heating
The key that the middle thermal efficiency is promoted, heating stroke is long, and heat exchange area is big.In the global design of flue, flue heat exchange pipe 15 counts
Amount is more, and 15 both ends of flue heat exchange pipe are connected to flue water tank 20, and 15 horizontal slice of flue heat exchange pipe is fixed in flue water tank 20
Big with smoke contacts area, time of contact is long, is heated again by heat exchange, and be admitted to circulating line.To flue gas heat
Amount makes full use of, and is another key factor for promoting the thermal efficiency.
2. fuel is launched automatically
In fuel delivery device, fuel is stored in material storing box 1, is cycloidal design inside material storing box, is made internal combustion
Material block all has maximum accelerated motion trend, and inclined plate baffle 21 and baffle 2 are used for stopping this movement tendency, fixed fuel
Position.Baffle 2 is under the driving of motor 3, and when baffle openings are overlapped with furnace wall opening when rotation, fuel, that is, exportable, which enters, combines cunning
Road 5.When motor 3 obtains a rotating speed, the opening and closing number of the baffle 2 of material storing box is also unique.In the effect of gravitional force
Under, fuel quickly glides on gerotor type face, into combined slide way 5, continues reliance on its own gravity potential energy, overcome frictional resistance into
Row downglide motion participates in heating process into combustion chamber of furnace body.After waiting for this fuel adding procedure, motor 3 drives storage
The rotation of baffle 2 of hopper is misaligned to baffle openings and furnace wall opening, and fuel stops launching.The two is mutually linked, different
Under motor speed, realize that the fuel of different frequency is launched.
3. the automatic adjustment of heating temperature
The feedback regulation of heating temperature refers to that the detection of heating temperature is realized by temperature sensor, feeds back to microcontroller
In, it is handled by internally stored program and optimal heating temperature is compared, and then control the rotating speed of motor, realize baffle rotation speed
Rate changes, and indirect control fuel is launched, and achievees the purpose that heating temperature is adjusted.In the present embodiment, heating temperature adjusting uses
The mode of close loop negative feedback ensures the output temperature of heating temperature.Temperature sensor 25 after detecting temperature information, itself
A/D conversion modules are converted into digital information and send microcontroller 24 to.Microcontroller 24 judges work(by internal processes language
Can temperature it is suitable whether, and then output order, the rotating speed of control motor 3, the addition of indirect control fuel realizes the tune of temperature
Section.
When the temperature detected is more than default heating temperature value, microcontroller 24 sends out the instruction for reducing rotating speed to motor,
The baffle openings of material storing box are reduced with the number that overlaps that furnace wall is open, and the fuel into combustion chamber is also reduced therewith, and heat source weakens,
Heating temperature reduces and is approached to preset temperature.
When the temperature detected is less than default heating temperature value, microcontroller 24 sends out the instruction to increase speed to motor,
The baffle openings of material storing box increase with the number that overlaps that furnace wall is open, and the fuel into combustion chamber also increases therewith, heat source enhancing,
Heating temperature increases and is approached to preset temperature.
By above-mentioned mediation practices, the automatic adjustment of heating temperature is effectively realized, without manual operation so that equipment
Using easy to operate.
