Work process
1. the thermal cycle of mechanism
Coal-fired soil heating boiler heating is to rely on the realization of thermal cycle.Recirculated water enters body of heater water tank 18 via water inlet 14, via helical heating pipe 16, absorbs heat in a combustion chamber and once heats.Afterwards, the water heated for the first time enters flue water tank 20 via connector, continues flowing by flue heat exchange pipe 15, absorbs the amount of residual heat post bake of fuel draining flue gas.The water that post bake completes i.e. participates in heating circulation by caliduct.In thermal cycle, helical heating pipe 16 is once to add to hanker the key that the thermal efficiency promotes, and its heating stroke is long, and heat exchange area is big.In the global design of flue, flue heat exchange pipe 15 quantity is many, and flue heat exchange pipe 15 two ends connect with flue water tank 20, flue heat exchange pipe 15 horizontal slice is big with smoke contacts area in being fixed on flue water tank 20, time of contact is long, is again obtained heating by heat exchange, and is admitted to circulating line.Flue gas heat is made full use of, is an up another key factor of the thermal efficiency.
2. fuel is thrown in automatically
In fuel delivery device, fuel is stored in material storing box 1, and material storing box is internal is cycloidal design, makes inner fuel block be respectively provided with the accelerated motion trend of maximum, inclined plate baffle 21 and baffle plate 2 and is used for stopping this movement tendency, the position of fixed fuel.Baffle plate 2, under motor 3 drives, overlaps with furnace wall opening when baffle openings during rotation, fuel the most exportable entrance combined slide way 5.When motor 3 obtains a rotating speed, the opening and closing number of times of the baffle plate 2 of material storing box is also unique.Under the effect of gravitional force, fuel quickly glides in cycloid profile, enters combined slide way 5, continues reliance on self gravitation potential energy, overcomes frictional resistance to carry out downglide motion, enters in combustion chamber of furnace body, participates in heating process.After this fuel adding procedure terminates, it is misaligned with furnace wall opening that motor 3 drives the baffle plate 2 of material storing box to rotate to baffle openings, and fuel stops throwing in.Both are mutually linked, under different motor speeds, it is achieved the fuel of different frequency is thrown in.
3. being automatically adjusted of heating temperature
The feedback regulation of heating temperature refers to be realized the detection of heating temperature by temperature sensor, feed back in single-chip microcomputer, processed by internally stored program, compare with optimum heating temperature, and then control the rotating speed of motor, realize the baffle plate speed of rotation to change, indirectly control fuel and throw in, reach the purpose of heating temperature regulation.In the present embodiment, heating temperature regulation have employed the mode of close loop negative feedback to ensure the output temperature of heating temperature.Temperature sensor 25 is after temperature information being detected, and self A/D modular converter is converted into digital information and sends single-chip microcomputer 24 to.Whether suitable single-chip microcomputer 24 is by internal processes language arbitration functions temperature, and then output order, controls the rotating speed of motor 3, indirectly controls the interpolation of fuel, it is achieved the regulation of temperature.
When the temperature detected is more than when presetting heating temperature value, single-chip microcomputer 24 sends the instruction reducing rotating speed to motor, and the baffle openings of material storing box reduces with the number of times that overlaps of furnace wall opening, and the fuel entering combustor reduces the most therewith, thermal source weakens, and heating temperature reduces and to preset temperature convergence.
When the temperature detected is less than when presetting heating temperature value, single-chip microcomputer 24 sends the instruction increased speed to motor, the increased frequency that overlaps of the baffle openings of material storing box and furnace wall opening, and the fuel entering combustor increases the most therewith, thermal source strengthens, and heating temperature increases and to preset temperature convergence.
By above-mentioned mediation practices, it is effectively realized being automatically adjusted of heating temperature, without manual operation so that the use of equipment is easy to operate.
