Algae-water separation device for salvage of blue-green algae

The utility model discloses an algae-water separation device for salvage of blue-green algae, which comprises an algae-water separation device, and the top of the algae-water separation device is fixedly connected with a gear box. According to the device, algae water is placed in the algae water separation device, the air pump is started, the air pump sprays air into the air spraying assembly, the air enters the algae water separation device and impacts the algae water, meanwhile, a flocculating agent is added, the motor is started, the output end of the motor drives the transmission bevel gear to rotate, and the algae water is separated from the algae water. A transmission bevel gear rotates and drives a first rotating gear and a second rotating gear to rotate respectively, so that a rotating pipe and a rotating rod can rotate and stir, and a stirring rod is driven to stir and mix in a reverse direction, the mixing efficiency is improved, algae flocculation is accelerated, and the algae-water separation devi
