The Optimization Research Of Screw Conveyor

The screw conveyor is the necessary device of modern manufacturing and material fluid transportation. In order to reduce people's heavy physical work, to raise working productivity, to achieve material-conveying automation and mechanization, it possesses very important practical significance. it has already widely used in many country departments.Screw conveyors are used extensively in industry for conveying and elevating bulk materials over relatively short distances. They are very effective conveying devices for relatively free flowing bulk solids.Yet, despite their apparent simplicity, designers tend to rely heavily on empirical performance data.This paper comes from an investigation practical problem, which is put forward during the institute of construction machinery research makes some surveys. In fact, for screw conveyors, there are many problems in design,use,engineering, such as configuration design, non-reasonable in parameters choice and not convenience of acting machines. Thus there is often defects when materials are conveyed, for example, material jam, noise, power wastage. These problems need urgent settlement.This dissertation uses a new, Genetic Algorithm optimization method, analyses deeply the whole machine's performance and parameters influence, researches material conveying mechanism, optimization of screw vane and screw.At last, some research mork are made about the influences of parameters during screw conveyors conveying bluks.this can direct latter research work about screw conveyors design work, and has practical significance.
