What Is Submersible Mixer

A submersible mixer is a mechanical device that is used to mix sludge tanks and other liquid volumes. Submersible mixers are often used in sewage treatment plants to keep solids in suspension in the various process tanks and/or sludge holding tanks.

The Functions of a Submersible Mixer

The submersible mixer is the key equipment in the sewage treatment process regulating the tank. It can realize the homogenization and flow process requirements of the solid-liquid two-phase flow in the deepening process of the sewage in the regulating tank. It is suitable for the occasion of solid-liquid mixing, through the submersible mixer. Stirring prevents sedimentation and the stratification of suspended solids. The submersible mixer has high safety and stable operation. The stirring angle can be adjusted freely to stir the suspended solids in all directions in the pool.

The submersible mixer adopting the novel method comprises a guiding tube, a shroud, an oil chamber, a motor, a transmission shaft, an impeller, and a cable, wherein the guiding tube is connected with the diversion hood, and the impeller and the motor are connected through a transmission shaft, and the motor The rotation drives the impeller to rotate synchronously. In this way, the overall structure of the device is compact and ingenious, and the impeller in the oil chamber has a better lubricating effect on the mechanical seal due to the lubricating oil in the oil chamber.

The mechanical seal and the bearing have less friction loss. After optimization, the swept-back impeller generates a large thrust. After the hydraulically optimized design of the shroud, the axial jet is greatly increased, so that the mixture is fully mixed and homogenized, and the liquid flow is accelerated. It prevents the sediment in the liquid from settling. Compared with other submersible mixers, efficiency is increased by 20%, and the energy-saving effect is remarkable.

Maintenance and Troubleshooting Tips for Submersible Mixers

Submersible mixers play a crucial role in wastewater treatment systems. As with any equipment, proper maintenance and troubleshooting are necessary to ensure their optimal performance. Here are three essential tips to help you with the upkeep and problem-solving of submersible mixers:

Regular inspection: Regularly inspect the submersible mixer for any signs of wear and tear, such as damaged propellers or leaking seals. This step ensures the longevity of the mixer and prevents potential breakdowns. If any issues are detected, promptly address them by replacing or repairing the faulty components.

Cleaning and lubrication: Keep the mixer clean and free from debris or sediment build-up. Regular cleaning not only improves the efficiency of mixing but also reduces the risk of clogging or damage. Additionally, ensure proper lubrication of bearings and seals to minimize friction and extend their lifespan.

Troubleshooting common issues: Some common issues that can arise with submersible mixers include motor overheating, excessive vibrations, or irregular operation. When troubleshooting, consider factors such as power supply, motor alignment, and impeller adjustment. It is also important to refer to the manufacturer's guidelines and consult with experts if necessary.
In addition to these tips, remember that timely maintenance and prompt troubleshooting can prevent major breakdowns, reduce downtime, and save costs in the long run. By following these guidelines, you can ensure the efficient functioning of your submersible mixers and maintain the smooth operation of your wastewater treatment system.

Applications of Submersible Mixer

Sludge treatment

Submersible mixer can help sludge mixing, avoid deposition, improve sludge concentration and consistency, reduce treatment time and cost.

Water treatment

Submersible mixer can be used in pools, storage tanks and water treatment plants, etc. To mix water bodies, promote water circulation and improve water quality.

Concrete mixing

Submersible mixer can be used in concrete construction sites for mixing concrete and cement paste to improve the quality of concrete.

Port construction

Submersible mixer can be used in the construction of ports and docks to mix the sediment in the harbor waters to maintain the depth of the waterway and improve navigation safety.

Fish pond farming

Submersible mixer can be used in fish ponds and aquaculture farms for circulating and mixing water bodies, increasing oxygen, improving water quality and promoting fish growth.

The Submersible Mixer Is Crucial for the Proper Treatment of Wastewater Pollutants

Submersible mixers can be completely immersed in water. They are used to treat wastewater before it enters another body or is reused. A wastewater treatment system performs several activities: preliminary treatment, primary treatment, secondary treatment, tertiary treatment, and sludge treatment. During preliminary treatment, screens are used to remove large, solid inorganic materials such as paper and plastic. During primary treatment, the wastewater passes through a sedimentation tank to remove smaller, solid organic materials using a gravity settling process. During the secondary treatment stage, an activated sludge process uses submersible mixers to break down any dissolved or suspended organic solids. This is followed by the tertiary treatment stage in which disinfectants, usually chlorine, are mixed into the water to eliminate harmful microbes. Finally, during the sludge treatment stage, the collected sludge is processed for reuse.

Submersible mixers use a wastewater pump during the secondary stage of the wastewater treatment process. During this stage, the wastewater pump or process water pump is used to aerate the liquid and prevent sludge sedimentation. Several different types of wastewater pumps are used. A suspended pump has a motor mounted on the top of the treatment pool that is supported by a shaft that connects the motor to the pump. A submersible pump submerges the motor, the pump housing, and the impeller in the treatment basin. Proper mixing (or aeration) of the wastewater is essential during this stage to properly treat the wastewater pollutants. A centrifugal pump has an impeller to force the liquid into motion using a centrifugal force to generate velocity. A propeller pump, or axial flow pump, has a vertical shaft for bottom suction and a propeller mounted near the bottom of the shaft. Propeller pumps are completely submerged (and can be clogged by large solids or trash) and therefore should only be used in clear water applications. Important wastewater pump specifications for submersible mixers include maximum discharge flow, maximum discharge pressure, inlet size, discharge size, and horsepower.

Submersible mixers are used to continually mix wastewater so that biological treatment can occur and dissolve any suspended organic solids using naturally occurring micro-organisms. Like other wastewater treatment equipment, they are used in a variety of industrial, commercial, military, and municipal treatment processing environments. Submersible mixers are convenient to install, are often energy efficient solutions, and provide energy consumption savings.
