Agitators are equipment used to homogenize media inside a tank. They operate by rotating immersed impellers at a controlled speed, known as revolutions per minute (RPM). The impeller's action induces flow and shear within the tank, facilitating the homogenization of single or multi-component media. This ensures that the media flows uniformly and maintains a consistent pattern.
Agitators serve various functions in industrial plants, including:
Paddle agitators consist of two flat paddle-shaped impeller blades extending to reach the tank walls. They are used if no extensive axial and radial flow is required. These impellers can produce a laminar low shear flow and are used for low viscosity liquid mixing, crystallization, dissolution, and heat transfer. They are typically operated at low speeds and predominantly give a tangential flow pattern. Secondary blades can be installed on the paddle blades to enhance the mixing of more viscous materials.
The impeller blades are inclined relative to the plane of rotation, creating an axial flow pattern. This design is commonly used for homogenizing suspensions and is a variation of the paddle agitator.
Anchor agitators feature impellers shaped like anchors, typically with a U-shape that matches the tank's contour. They predominantly generate a tangential flow pattern but can incorporate angled blades on their horizontal supports to produce an axial flow.
These agitators are used for blending and heat transfer of highly viscous liquids. Their impellers create a laminar, low-shear flow, making them ideal for mixing shear-sensitive media. Anchor agitators are among the most economical options for laminar flow agitation and are suitable for tanks with rounded or conical bottoms. The impeller design allows for low clearance with the tank wall.
Helical ribbon agitators feature a helical impeller blade mounted on a shaft by rods. These impellers serve as an alternative to anchor impellers and are designed to generate an axial flow pattern. They provide a higher fluid contact area, making them effective for mixing fluids with higher viscosities.
Double helical ribbon agitators feature two helical blade flights running through the shaft in opposite directions. This design improves the mixing of more viscous fluids. They are also used in heat transfer applications and are regarded as the best impeller for high-viscosity laminar flow. The impeller can be designed with low clearance to the tank wall.
Propeller Agitators
Propeller agitators primarily produce an axial flow pattern, though they can also create a tangential flow. The fluid is displaced and accelerated along the length of the tank as the impeller blades draw it in. The inclination of the impeller blades affects how the fluid is deflected. These blades are tapered towards the shaft to minimize centrifugal force and maximize axial flow.
Operating at medium to high speeds, propeller agitators often use marine propellers.
They are commonly used for homogenizing, dispersing, and suspending low-viscosity products. In solid-liquid suspension systems and chemical reactors, propeller agitators help prevent solids from settling at the tank bottom. They can be installed in unbaffled tanks, either vertically inclined from the centerline or positioned off-center.
