The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described.
Burning roller kilns with 7 * 1400 coals is example: burner hearth 5 is provided with 7, and it burns till 1.4 meters of width, and 58 meters of stove total lengths are made fuel with the block bituminous coal (wherein containing 20% left and right sides broken coal) of low heat valve 5740 kilocalorie/kilograms.At salband long 4 meters, wide 1.6 meters, high 0.4 meter heating surface (area) (HS being installed is 15 square metres air preheater 2, in air preheater 2 imports one 750 watts, 220 volts air blasts 1 are installed, its outlet is connected with the main air supply duct 16 of 350 millimeters of diameters, 12 meters of length.Air-distribution device 6 is set in turning over wall with flues 18, long 1200 millimeters, wide 820 millimeters, high 500 millimeters of vertical air intake passage of air-distribution device 6, long 50 millimeters, wide 50 millimeters of its transverse air-intake passage, be evenly distributed, arm by 150 millimeters of diameters between the import of 0~7# air-distribution device 6 and the main air supply duct 16 is connected, and is provided with air quantity adjustment doors 15 in the arm.250 millimeters of aid distributing pipe 14 diameters are communicated with main ajutage 16, and the other end inserts exhaust gases passes 9.Be provided with the automaton of control plate 11 in flue 12, the plate automaton is made up of electric cabinet 10, motor, decelerator, lifting device, limit switch etc., and motor is the stepless variable-speed motor of 1.1 kilowatts of power.At the coal filling hole 3 of each burner hearth 5 signal receiving device 4 is installed respectively, air blast 1, electric cabinet 10, signal receiving device 4 all are connected with Main Control Tank 8 by signal control line 7, and signal control line 7 is located in the circuit sleeve pipe 25.
Its course of work is: bituminous coal is lighted a fire from the grate 26 that coal filling hole 3 is deposited in the burner hearth 5, and the slag in afterburnt falls in the slag hole 17.The product of compression moulding places on the porcelain tube 22, and porcelain tube rotates under chain drives, and product is sent to high temperate zone from the preheating zone, and the heat that raw coal combustion produces passes to product by silicon plate 21, and firing zone and top, cooling zone hide with cover plate 20 and high temperature cover plate 23.When product during by the chilling band, with the air preheater 2 below the heat transferred lower cover 24 to add hot-air.When any one burner hearth 5 coal, signal receiving device 4 passes to Main Control Tank 8 with this signal by signal control line 7, at this moment, Main Control Tank 8 control air blasts 1 start, by the electric motor starting of electric cabinet 10 control flue plugboard automatons, promote plate 11, after plate 11 rises to specified altitude simultaneously, limit switch passes to electric cabinet 10 with signal, and motor is out of service.Behind the certain hour (installed by Main Control Tank 8 and electric cabinet 10 fashionable dresses decided at the higher level but not officially announced fixed), air blast 1 is out of service automatically, reverses after the motor commutation of plate automaton, and plate 11 moves down into behind the predetermined stroke out of service automatically, and plate 11 resets.The cold wind that air blast 1 is sent heats the laggard air supply duct 16 of becoming owner of in air preheater 2, enter air-distribution device 6 and exhaust gases passes 9 respectively through arm air quantity adjustment doors 15 and aid distributing pipe 14 again, evenly enter burner hearth 5 after the air that enters air-distribution device 6 heats once more, raw coal is fully burned.Burn away after the hot-air that a small amount of black smoke that dead angle area produces is sent here with aid distributing pipe 14 exhaust gases passes 9 in mixes, enter flue collector 12 from exhanst gas outlet 19, pass through chimney 13 at last and be discharged in the atmosphere far below the flue dust of discharge standard.
