What Is a Submersible Mixer?
The submersible mixer is also known as the submersible propeller. It is suitable for the process of sewage treatment plants to promote the stirring of wastewater containing suspended solids, sludge, industrial process liquids, etc., to create a water flow, strengthen the stirring function, and prevent the sedimentation of sludge. Process important equipment on the process flow. Divided into mixed submersible mixer, low speed submersible propulsion mixer.
- It is suitable for aeration tanks and anaerobic tanks of industrial and urban sewage treatment plants. The water circulation in the tank and the nitrification, denitrification and phosphorus removal stages can be used to create water flows.
- 1. The mixing and stirring series products use multi-pole motors, which adopt a direct-connected structure, which has low energy consumption and high efficiency; the impeller is precision-cast or stamped with high precision, large thrust, beautiful and smooth appearance, and compact structure.
- 2. Low-speed push-flow series products use cycloid pin gear reducer or gear reducer, equipped with low power, low speed, large impeller diameter and wide service area. The impeller is made of polyurethane material and aluminum alloy (also made of glass fiber reinforced plastic). It has high strength and strong corrosion resistance. In addition to its stirring function, it also has the function of pushing and creating water flow.
- 3. The motor winding of the submersible mixer is Class F insulation and the protection level is IP68. Combined use in the aeration system of the sewage plant can greatly reduce the energy consumption of the system and significantly increase the oxygenation amount, which can effectively prevent precipitation. According to process requirements, direct-connected diving agitation can be equipped with a shroud [1]
- Mixing and stirring series submersible mixers are suitable for various water treatment processes and industrial processes where solid, liquid two-phase or solid, liquid, and gas three-phase media are required to uniformly react.
- The stirrer should be able to run normally and continuously under the following conditions:
- 1. The maximum medium temperature does not exceed 40 ° C;
- 2. PH value of the medium is between 5-9;
- 3. The liquid density does not exceed 1150kg / m 3 ;
- 4. Long-term diving operation, the diving depth generally does not exceed 20m.
