Rotary furnace feed hopper crucial to ensure that the material surface smooth, and the rotary distributor can feed fuel evenly scattered material surface, the material surface shape adjustable cloth. Application of Frequency Control, PLC control, making cloth accurate and reliable. Distributor in key structures such as barrel, baffles, fabric guides, sprinkle stone etc. high temperature resistant, corrosion-resistant stainless steel. Rotating part of the plane with a special high-temperature bearings, making the device reliable operation in harsh environments and long-term continuous trouble-free operation. Limestone calcination provides a good quality of process conditions. The special structure capable of limestone and coal hopper evenly mixed spilled into the material surface. Greatly reducing the situation caused by the furnace due to the cloth uneven nodulation serious waste of fuel. After water Steel, Jinan Iron and Steel, and other units in the replacement of the species distributor, through actual savings per ton of ash coke (or coal) in more than 15Kg. PLC system configuration: 1, the original design uses two sets of Siemens S7-200 series PLC, based on actual experience of our company, now replaced by the use of a set of Siemens S7-300 series PLC control, lime kiln equipment, so that the original 2 sets of CPU S7-200 into the present station S7-300 CPU 1, the original Ethernet communication module 2 becomes now an S7-200 station S7-300 Ethernet communications module, lime kiln, the remaining modules priced fairly, which can save a lot of costs, reduce the company's costs. Programming software using STEP7 V5.4 (Authorized Genuine), monitoring software WINCC6.0 Chinese version (genuine licensed). Between PLC and PC using Ethernet communication mode, in the main control room set up industrial Ethernet switches, PLC system I / O margin greater than 20%. 2, HMI operating with two operating stations, PC Advantech IPC (dual hard drives, optical drives, UBS port, memory 2 × 512, CPU-P4 2.8), lime kiln manufacturing, 21-inch Philips tuck crystal display, green lime kiln , have adopted the popular configurations. 3, for the actual situation of the scene, the scene is set for each kiln 2 meter box, mainly 8 kiln temperature and two gas temperature transmitter (DC4 ~ 20mA). 4, each I / O module DC24V power alone switch. 5, configure the analog input module with electrical isolation and fuse terminal blocks, to protect the module is not damaged.
