Abstract
The design is environmentally friendly project in Zhejiang Huadian in light of the realities of production and design.Crusher of the coal-fired thermal power plants and other business-critical boiler slag handling equipment. As the burning coal is not fixed, boiler slag discharge a large quantity, prone to hard slag block, fishing residue in the machine running, often hard slag block Kasai, resulting in fishing gear boxes slowdown Slag fault or deformation of the ball coupling , And other failures. So into the Crusher of the slag block often Kasai reamer teeth, resulting crusher machine failures, such as frequent tripping. Seriously affected the normal production. The improved Crusher aircraft comprehensive study of the current domestic range of advanced Crusher machine, analysis of the Cleaner system on the basis of the actual process designed by. From the view of the world, PLC is the largest, most extensive scope of application of automation products, but also can be said to be the most practical automation products. This design is PLC in a motor control applications, because the PLC to automatically use a lot of advantages, the system would greatly simplify the hardware equipment, the volume decreases, and PLC's anti-interference capability and high reliability, operation and maintenance Simple. Therefore, this design selected Siemens S7-200PLC as the main control device, plus a simulated through the extension of the machine so as to enhance the fault of the police and handling capacity. The improved Crusher single machine can use, can also be integrated in the boiler slag handling system, automatic fishing Slag, which would greatly enhance the boiler Cleaner degree of automation, and enhance productivity.
