Environmental Reamer Device Design And Fluid Performance Study

Environmental protection is the hot topic in today's society, and environmental protection shape is dredging engineering and environmental protection engineering, through the combination of two comprehensive management, that is, to the purpose of the "s" shape, and realize the goal of ecological reconstruction. Environmental protection "s" shape tool is the key enforcement of environmental bait-casting engineering hardware conditions, environmental protection bait-casting machine has two main types, one kind is and dredging ship match, and ground of suction hoper dredger matching called environmental protection reamer; Another kind is specially developed and can use have environmental protection function of independent of dredging bait-casting device.In the structure design, this paper according to wring suction hoper dredger and environmental protection shape tool operation principle and features of whole ground suction hoper dredger in accordance with the technical characteristics of the environmental protection requirements for structure design, whole ground of suction hoper dredger dredging requirements and practical engineering experience the formula to calculate the length of the environmental protection "s" shape tool, diameter on structure scale. Secondly, according to the environmental protection "s" shape tool in the work required, using experience of work calculate out lateral movement speed, speed and shaft power of dynamic parameters and the strength check out knives.In the fluid property research, this paper use Solidworks software build sure size reamer model and install a mask, namely shell covered the tapered spiral reamer, shell the cutting of sediment and water restrictions in the mix, will cover shell internal flow field around knives into the shell and cover outside shell two parts, the shell is mud, and cover the shell is water, finally, in different power under the speed of flow field and pressure distribution vector diagram, and suggests that the best power the environmental protection effect is good.
