In the deteriorating environment , the increasing scarcity of non-renewable resources , environmental protection , energy conservation has penetrated into all aspects of social life . Flush toilets cost in view of the traditional water resources , pollution of the environment , and many other defects , and combined with the research status at home and abroad , our environmentally intelligent type water - free toilet flushing institutions research topic. Free water flush toilets Research and Development in the Education Department of Anhui College provincial natural science key research project \design , optimization and checking . First, the characteristics of the environmental intelligent Free water flush toilets , function , works , combined with research situation , pointed out the need for environmentally intelligent water - free toilet flushing institutions . On environmentally smart free water flush toilets mechanical part of the design , including the design of the drive system , mixing system design as well as the design of the exhaust system , and a special presentation on the structure of the main components of the spiral drum , drive , install , layout. On this basis , the principle of movement of materials . Secondly , the use of three-dimensional model of a spiral drum major CAD design software , Pro / Engineer , static analysis of large finite element analysis software ANSYS platform , spiral drum , to get structures under static loads node the stress cloud and deformation of cloud images . For spiral drum design optimal , from changing the structure parameters and material properties are optimized . Then optimized the dynamic characteristics of the finite element model checking . Obtained by modal analysis , the previous order of the spiral drum natural frequency, mode shape and stress distribution . According to the the spiral drum harmonic response analysis , calculated the of spiral drum in several frequency response and get some response frequency curve , in order to ensure the stability of the dynamic performance of the optimization model . Finally , through a comparison of the optimization results , analyze the economics of the use of environmentally intelligent free water flush toilets , make the outlook and prospects for their use .
