Submersible mixers are used in wastewater treatment and industrial processes to create a slurry, break up solids, or limit stratification. They consist of inclined blades rotated by a motor, creating a vortex to promote circulation and uniformity. They can be energy-efficient and adjustable in speed, and may require proper sizing for thick and heavy slurries.
A submersible mixer rotates inside a tank of fluids to create a slurry, break up solids or limit stratification. Such devices are commonly used in wastewater treatment and also have applications in industrial processes such as the manufacture of paints, pharmaceuticals, pastes and sludges. They can be paired with other mixing equipment in some settings; for example, an overhead stirrer can be added to mix from above as well as from within.
This equipment is characterized by a series of inclined blades rotated by a motor. The blades, turning, create a vortex in the liquid compound, promoting its circulation. They are designed to operate in submerged conditions and should not clog or stall. As the material moves through the mixer, it can also be chopped and crushed, ensuring that the solids within the tank are of a uniform size and consistency.
For wastewater treatment, a submersible mixer can help maintain a consistent slurry of solids within a slurry. This makes it easier to fully aerate the mix and move it through processing stages, from raw wastewater to fully treated materials. Similar equipment can be useful for manure storage, slaughterhouse waste processing and similar environments.
Another use for a submersible mixer is in manufacturing and industrial production. Mixers inside large tanks can create and maintain suspensions of materials such as paper pulp. Fully mixed material can be routed to the next processing stage to make room for a new load. This enables extremely high volumes of material to be processed in large tanks used in pharmaceutical, chemical and other industries.
Size and performance may vary. Some equipment is designed to be energy efficient and may run more slowly or have other features designed to reduce overall energy consumption. Speed is typically adjustable to allow technicians to control various situations and stop mixing when needed. It may also be possible to completely remove a submersible mixer for maintenance and inspection while the tank is still full, usually by mounting the equipment on a rail or rail.
The best option for a given setting may depend on what is being mixed and the facility’s future requirements. Submersible mixers must be properly sized and capable of handling conditions in tanks that may contain thick and heavy slurries. You may also need to consider the possibility of increased workloads in the future which may require high-speed processing with a submersible mixer to keep up.
