Blue carbon is also called carbocoal ,coke powder, is made by using high quality Jurassic clean coal block teemed with ShenFu coalfield, as a kind of new type carbon materials, with its high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum content, low sulfur content and low phosphorus characteristics, gradually replace metallurgical coke and widely used in calcium carbide, ferroalloy, ferrosilicon, Silicon carbide and other products production, become a kind of irreplaceable carbon materials.Blue carbon (people also say semicoke, coke), structure for massive, the grain size general above 3 mm, the pale black color, at present, blue carbon basically have two kinds of specifications: one is the soil refined blue carbon, the other is machine-made blue carbon. Although two specifications blue carbon uses the same quality coal refining into, but because of the different production technology and equipment, its cost and quality are different.Blue carbon dryer is mainly composed by the barrel, transmission device, riding wheel device, raising material plate, sealing equipment etc. Our company with many years of practical experience developed new high efficiency energy saving rotary dryer. Compared with the traditional rotary dryer, the drying efficiency is higher, energy consumption is lower, yield is higher, running is more stable, sealing is better, widely adaptive and deeply user’s praise and recognition.The main performance characteristics1, heat source select fluidized bed furnace:Fuel of this type wide adaptability, can use all sorts of coal, especially use almost no volatile coke or coke breeze. Combustion temperature is lower, in burning process can effectively control the emissions of Nox and Sox, is a “clean“ combustion technology, burn-off rate is high, high thermal efficiency; great section thermal intensity, the bed layer’s heat transfer ability is high, can reduce the furnace hearth volume and steel consumption. Load regulation broad/covering a wide range, heating stability properties is good, Ignition convenient, damping-down time is long, lime-ash is not easy to soften or cementation, activity good, easy to comprehensive utilization.2, efficiently combination raising material plateAccording to the physical property changes in the drying process of the material, uses many kinds of structure of combination raising material plate, make the material in the cylinder to form even material curtain, and with the hot flue gas fully proceed heat transfer and mass transfer, as to the high humidity viscous material, will have the jam resistance materials and break to accumulate the ball chain device. As to good liquidity material, the spoon-type of arc plate, etc. So let the unit volume evaporation strength reach to 40 ~ 80 kg/m3. H, evaporation strength improve 50 ~ 100% than the traditional rotates dryer.3, “Adjust center” riding wheel deviceUsing bearing type and structure form which different from the traditional dryer’s riding wheel, riding wheel and tyre self-constrain and keep line contact, the friction surface contact more board and equilibrium, to ensure the service life of riding wheel and tyre, enhance the cylinder operation stability. And properly reduce included angle between riding wheels, reduce operation resistance, lower power consumption.4, reasonably adjust rotate speedAccording to differ physico-chemical properties of drying material, drying retention time are different, design adopts the best rotate speed operation, fully guarantee the drying quality, general equip with electromagnetic speed regulation motor or frequency control motor speed motor.5, design of dust collecting tail cover According to the requirements of different dry material, enlarge cavity design tail cover and change the exhaust flow, let the tail cover to get primary role to collect dust, greatly reducing the collect dust pressure to subsequent dust collector.6, new type sealing deviceThe dryer’s before and after seal ring take example by rotary kiln seal device, composed by maze/ labyrinth device, heat resistance and wear-resisting, sealed performance is good, long service life, convenient installation and maintenance.technical parameters NormsmmxmBarrel volumnBarrel gradientMotor modelPowerReducertype Overall dimensionsWeightTHZG1500X12 21.2Y280L-615JZQ65012000X2055X2895917.13HZG1500X14 24.9Y180L-615JZQ65014000X2655X289518.33HZG1800X10 25.45Y180L-615JZQ65010000X3060X298017.93HZG1800X12 30.5Y200L-618.5JZQ65012000X3060X298019.89HZG1800X14 35.1Y200L-618.5JZQ65014000X3060X298020.85HZG1800X18 45.85Y200L-622JZQ65018000X30609X98022.3HZG2200X12 45.6Y200L-622JZQ75012000X3620X357030.31HZG2200X14 53.2Y200L-622JZQ75014000X3620X357032.23HZG2200X18 68.4Y225M-630JZQ75018000X3620X357034.15HZG2200X20 704.4Y225M-630JZQ75020000X3620X357036.07HZG2400X24 63.33.85Y225M-630JZQ85014000X3860X376059.9HZG2800X24 147.8Y225M-675JZQ85015000X4060X396097HZG320025176.55Y225M-675JZQ100025000x5000x4500110。
