The Design And Research Of Clinker Cooling Flow Regulation And The Electro-hydraulic System

With the rapid development of China’s economy, the development of the cementindustry by leaps and bounds, the cement industry is the high energy consumption andhigh pollution. In response to the call of the national energy saving, it is necessary tooptimize the transformation of the cement industry. Grate cooler is the energy savingequipment in cement production, and bear the task of cooling and heat recovery. Therefore,it is necessary to conduct a study to improve the grate cooler.This paper studied and analysis from two aspects of clinker cooling and conveying:First, the reasons of clinker "Red River" phenomenon is caused by the unevendistribution of the cooling gas, and analysis of the operating state of the clinker in thecooling machine, proposed clinker unit division to achieve equilibrium for coolingpurposes, the establishment of a cooling gas flow control model. Seepage mechanics thetypical Ergun equation is based on the calculation of the flow resistance of the clinker,compared with the actual flow resistance, laid the theoretical foundation for the design ofthe new flow regulator. Based on fluid dynamics, and the establishment of a new flowregulator design formulas.Then, through the analysis of the grate cold machinist conditions, decided to use loadsensitive technology and electro-hydraulic proportional technology to control, design agrate cooler Hydromechatronics system, and then analyze and compare the hydrauliccylinder cushion device, to determine cone annulus buffer means as the buffer means.Finally, through the use of simulation software AMESim simulated the keycomponents of the load-sensing pump, determined pump performance feedback port size,and system modeling and simulation and experimental studies prove the design of thesystem operates in accordance with the provisions of reach desirable properties.
