Learn the design of a mixing tank and how it actually works

Mixing tanks include stainless steel mixing tank, vertical chemical mixing tank, liquid mixing equipment, square tank, solvent tank and underground storage tank. I mainly share the design and working principle of the mixing tank:

1. Sanitary design of mixing tank

Agitator and agitator shaft assemblies passing through seals shall be smooth in design and construction and all surfaces shall comply with all sanitary design standards applicable to product contact areas. The agitator shaft assembly should be easily accessible in order to effectively clean all surfaces by spraying, directional flow, dipping, or cleaning in place. The agitator end shall have a small area of surface immediately adjacent to the receiving end and shall not exceed the length necessary to ensure proper incorporation of the ingredients into the mixture.

Agitator product contacts should be designed to minimize gaps, voids and dead corners in the grooves. All voids shall be closed by welding or approved sealing techniques (O-rings, seals, etc.) so that the surface is flush and there are no cracks at metal-to-metal contact points. Metal-to-metal joints (e.g. keyways, hub-to-shaft joints, hub-to-end cap joints, etc.) may allow product and/or microorganisms to enter and accumulate.

Two, pulse air mixing tank system

Powerful mixing tank system includes mixing and blending of liquids. In addition, this innovative technique uses sequential jet pulses or pulses of compressed air or gas. In this way, the pulses are released through a series of flat disks called battery plates, which are attached to the bottom of the tank. By strategically placing the accumulator plate on the tank bottom plate, almost 100% of the tank liquid can be mixed evenly.

Three, mixing tank system technology

The process of releasing bubbles in a sequence of time intervals. This creates a direct vertical circulation in the tank and mixes 100% of the contents of the tank. The sudden release of air jolts the liquid and causes its molecules to move. As a pulse of air is "squeezed" under the open battery plate. It shoots laterally in a 360 degree direction, sweeping through the settled solids on the tank floor, creating a pressure zone around the plate.

The air then builds up on the plate in large oval bubbles. Beneath these large, wide bubbles, a vacuum is created, pulling the liquid and solid at the bottom quickly to the surface. Immediately after the pulse of compressed air is released, gravity and physics begin to force the bubbles to the surface of the liquid. As the bubble rises, it also pushes the liquid above it up and out towards the perimeter of the tank. Pulsed air mixing tank technology requires no moving parts and minimal maintenance, reducing the additional maintenance, downtime, and expensive maintenance costs typically required for mechanical mixing tank systems.

Four, mixing tank system installation

The size of the bubbles, pulse frequency, and number of accumulator plates in the tank depend on the diameter and geometry of the tank. When designing a pulsed air mixing system for your tank, consider mixing targets and liquid types as well.

The mixing tank system is easy to install. Once installed, they require minimal maintenance. Pulsed air mixing systems are sold as kits that include a set of tank drawings (for PPC systems). This allows the customer or contractor to save on installation costs.
