Abstract

We select the horizontal mixer as our main type because the design is mainly used to  stir soup of magnesium chloride plus wood.First,we need to choose a general plan. Then the design of vital components is needed. It is made up of mixing device, stirring drive system, feeding, unloading system, rack and walking systems.Design of the main content is concrete mixer rack design, These mainly include: rack structure of the programme of identification, rack between all the components determine the location of, all the components on the rack and rack of connections and installation of position, the determination of rack form factor, the selection frame steel structure . Checking the stability of the rack, complete plans and parts rack assembly plans.Then,choosing a electrical motor and reducer is a must.The section of simulation is aimed to get the chart of contous of statio pressure by using the software named fluent.At last,the misson is to discuss about the design according to the result of the simulation.The mission completed in time,and the simulation succeeded.

Key words:Horizontal mixer;Two phases; Simulation of fluid; Fluent
