Problems solved by technology

However, when the propeller drives the aerator head to rotate at a high speed to form a strong negative pressure, it will cause the adsorption of a large amount of impurities in the water, block the outer cover that protects the aerator head, and affect the full fusion of water and air, resulting in unsatisfactory oxy

Example Embodiment

[0018] Specific implementation methods: such as figure 1 As shown, a spiral diversion type submersible jet aerator includes a submersible motor 3 fixed underwater through a support rod 1. The support rod 1 is a hollow pipe, and an air intake pipe 2 is arranged in the pipe. The front end of the submersible motor 3 A flow mixer 4 is provided, and the air inlet pipe 2 is connected to the flow mixer 4. The front end of the flow mixer 4 is provided with a spiral deflector 5; There is a helical blade inside, the central axis of the helical blade runs through the flow mixer and is fixedly connected with the motor shaft; the helical blade is fixedly connected with the guide cylinder. The flow mixer 4 is conical, and the inlet ports of the flow mixer are arranged on the left and right sides of the flow mixer respectively. The water inlet channel is between the spiral deflector 5 and the flow mixer 4, and the inner cavity of the flow mixer 4 is an air intake channel. like figure 2 ...

Abstract

The invention relates to aerator equipment, in particular to a spiral guide type submersible jet aerator. The spiral guide type submersible jet aerator comprises a submersible motor fixed underwater through a supporting rod, wherein the front end of the submersible motor is provided with a mixer, an air inlet pipe is connected onto the mixer and the front end of the mixer is provided with a spiral guide device; the spiral guide device comprises an external guide cylinder, a spiral blade is arranged in the guide cylinder, and a center shaft for the spiral blade penetrates through the mixer and is fixedly connected with a motor rotating shaft; the spiral blade is fixedly connected with the guide cylinder; the mixer is conical and the mixer is provided with an air inlet interface; a water inlet passages is arranged between the guide cylinder and the mixer, and the inner chamber of the mixer is an air inlet passage. The spiral guide type submersible jet aerator has the advantages that the sedimentation of large particle sand can be prevented, the aerating efficiency of the aerator is improved, the used land is reduced, the power cost is decreased and the sludge backflow lifting effect is enhanced.

Description

technical field [0001] The invention relates to aerator equipment, in particular to a spiral diversion type submersible jet aerator. Background technique [0002] The spiral diversion submersible jet aerator produces high-speed water flow through the nozzle through the spiral deflector, forms a negative pressure around the nozzle to inhale air, and mixes with the water flow through the flow mixer to produce a water-air mixed flow, which entrains a lot of bubbles in the water flow Fully stir in waters with a large area and depth to complete aeration, its shaft power does not change with the change of submersion depth, and the air intake can be adjusted. Therefore, the spiral diversion submersible jet aerator can be applied in pools with large water level changes. However, when the propeller drives the aerator head to rotate at high speed to form a strong negative pressure, it will cause the adsorption of a large amount of impurities in the water, block the outer cover that p...
