High speed submersible mixer

High speed submersible mixerIt is a machine equipment that can deeply stir liquids. It can be used in many different fields and applications, such as wastewater treatment, aquariums, and chemical processing.

1. Mixing suspended solids and dissolved oxygen

A submersible mixer can mix suspended solids and dissolved oxygen to aid in biological growth and chemical reactions. It can rotate in the mixing tank at the bottom to mix the water, thereby increasing the dissolved oxygen level in the water. This helps maintain the life of aquatic organisms and promotes the occurrence of biological reactions.

2. Mixing and accelerating sludge sedimentation

During the sewage treatment process, submersible mixers can help mix and accelerate the sedimentation of sludge. It can rotate in the sedimentation tank to mix and stir the sludge, making it easier to settle and remove. This helps to improve the efficiency of sewage treatment and reduce treatment costs.

3. Maintain liquid circulation

High speed submersible mixerWhen used in conjunction with the aeration system in sewage treatment plants, it can greatly reduce energy consumption and significantly increase oxygen filling, effectively preventing sedimentation. According to the process requirements, the direct coupled submersible mixer can be equipped with a guide cover.

Due to the long-term operation of submersible mixers underwater, sealing performance is crucial for them. At present, different manufacturers have different sealing methods for submersible mixers. Many submersible mixer motor shaft seals on the market are external, and their medium leakage direction is the same as the centrifugal force direction, resulting in a large leakage amount. The QJB series submersible mixer motor shaft seal adopts two independent series connected mechanical seals, forming two reliable sealing defense lines. The mechanical seal is located in the inlet medium of the mixer, relying on the stopper of the rotor wheel shell and oil chamber to prevent large debris from entering the mechanical seal area, so as not to affect its normal operation. In order to adapt to medium pollution conditions, wear-resistant materials (silicon carbide/silicon carbide) are selected for the mechanical seal friction pair to ensure durability and normal operation. The mechanical seal is located in the oil chamber, and the working conditions of the mechanical seal in the oil chamber are good, so silicon carbide/graphite is selected as the friction pair. The series connection of two mechanical seals can provide safer and more reliable protection for the motor.
