ABSTRACT

The Turbine Mixer was Fabricated at the Mechanical Engineering Workshop of Institute of Management and Technology, Enugu.

The method of the fabrication of the turbine mixer involved a preliminary computation of the dimensions of the standard turbine in relation to the dimension of the reacting vessel in which they will be used in, making out, cutting out to sizes, rolling folding, welding, body – filling, filling, glass – papering and painting.  The total surface area is 10741.5CM2

The first step taken in the fabrication of ht said project was the selection of the material suitable for the construction.

The materials used in the construction were locally sourced and were selected to suit the desired purpose.  The mild steel was used instead of galvanized steel due to its relative low cost.

The mild steel was located with paint to prevent corrosion attack and deterioration of the work.

The dimensions of the project were as follow 31.0CM.  for the height and –21.0cm for the diameter.  The volume [capacity] of the cylinder is 10,74 1.5cm3 the average speed of the turbine mixer is 125pm.  The turbine mixer is manually operated a design that is meant to save cost.

INTRODUCTION

The multiple of process and mechanical variable makes fluid agitation one of the most complete unit operations. For this reason the systematic studies of underlined me chemise of mixing operation progressed slowly, quantitative design data is spores and almost innumerable agitator configuration have evolved. Though often confused, agitation and mixing are not synonymous. Agitation refers to the induced motion of a material in a specified way, usually in a circulatory pattern inside some sort of container. Mixing is the random distribution into and through one another of two or more initially separate phases. Ex A single homogeneous material such as a thankful of cold water can be agitated, but it cannot be mixed until some other material is added such as powdered soerd.

However, many processing operations depend to their success on the effective agitation and mixing of fluids. To enhance these processing operation, Experimental agitators were developed to serve a wide variety of poetical and fundamental fluid mixing problem.

Experience has revealed that reaction that recurred mixing and agitation most often cannot perform without agitators. That is why the need to discuss agitators, Agitations and mixing can not be over ruled and has to be given to student in the territory institution as project work.

Mixing is been used to perperon on uniform combination of two or more substances. The material fed to a mixer could be gasses, higuidion solids. The product that is from mixer may be homogeneous or heterogeneous substance.

THE OBJECTIVE AND THE SCOPE OF THE PROJECT

Turbine mixer is one of the important equipment found in the chemical industries. It is been applied in variety of operations in the industries and homes such as mixing of solution of liquids, solids and gases.

The main objective of the project is to construct turbine mixer that will be widely versatile in application / operation.

This material content is developed to serve as a GUIDE for students to conduct academic research
