Liquids are agitated for a
number of purpose, depending on the objective of the processing step,
soe of the purpose includes
1. Promoting heat transfer between the liquid and a coil or jacket
2. Blending immiscible liquids, for example, methyl alcohol and water.
3. Dispensing a second liquid, immiscible wt h the first to form an emulsion or suspension of fine drops
4. Suspending solid particles
5. Dispersing a gas through the liquid in the form of small bubbles.
A
typical application of propeller agitator is in mixing of high
viscosity liquids or solid in solids. Most factories produce and
products using blended liquids like in the confectionery industries,
liquids food drinks like canned juices as well as canned and bottled
drinks.
Many a times, one agitator serves several purposes at the
same time, as in the catalytic hydrogenation of a liquid, in a
hydrogenation vessel, the hydrogen gas is dispersed through the liquid
in which solid particles of catalyst are suspended, with the heat of
reaction simultaneously removed by a cooling coil or jacket.
1.1 OBJECTIVE OF THE PROJECT
The objective of the project is to construct a portable propeller
agitator with high efficiency and durability, which will be used for
good mixing operation in smalls scale industries or in the laboratories
and other applications such as domestic and pharmaceutical industries.
The preferred choice of raw material of the construction is mild steel
because of it’s excellent properties which included high resistance to
corrosion, machineability, ductility, malleability, it resistance to
react with the material or reactant when agitating as any reaction
between the vessel and the material to be mixed will affect the
product. Moreover, it is cheap and available.
The
dimensions of the propeller agitator are length of handle = 320mm,
diameter of gear teeth = 100mm, thickness of shaft = 20mm, thickness of
gear = 12mm, size of blade = 50mm x 100mm, blade diameter = 63mm, inside
diameter of pump = 12mm outside diameter of pump = 20mm, shaft height =
470mm, vessel diameter = 340mm and vessel height = 560mm.

ABSRACT - [ Total Page(s): 1 ] Propeller agitator is a specialized of various types of substances. It consists of three basic components which are the shaft, blade and the vessel.         In the construction, mild steel was chosen due to it’s inherent properties. After the procurement, the following constructional operations were carried out which included marking out, center punching folding, welding, filling operation, assembling, and painting to beautify the equipment and for other purposes.     ...
