[0002] Submersible flowmeter is an important sewage treatment equipment, which is widely used in biological sewage treatment process. The main function of submersible flowmeter is to prevent the deposition of activated sludge in the biological pool.

[0003] The existing submersible flow propeller includes a motor and a spiral propulsion impeller, which is coaxially fixedly connected to the output shaft of the motor, and the motor is fixedly connected to the base in the sewage tank. When in use, the spiral propulsion impeller of the submersible flow propeller rotates and stirs the liquid to produce a rotating jet under the drive of the motor, so that the liquid other than the rotating jet produces a stirring effect through friction, so that the activated sludge and sewage are fully in contact and react, improving the water quality, increasing the oxygen content in the water, and effectively preventing the deposition of suspended matter.

[0004] When a submersible flow thruster fails, it needs to be repaired in sewage, and the sewage in the sewage pool needs to be drained before repairing, which increases the difficulty of repairing the submersible flow thruster. Utility Model Content
