an oxygenation device

Abstract

The invention discloses an oxygen aeration device which comprises a floating body, a water pumping impeller and a drive mechanism which drives the floating body and the water pumping impeller to rotate respectively, the drive mechanism comprises a motor and a speed reducer in transmission connection with the motor, the speed reducer comprises a first transmission mechanism and a second transmission mechanism, the first transmission mechanism is in transmission connection with an output shaft of the motor, the second transmission mechanism is in transmission connection with the first transmission mechanism, the first transmission mechanism is fixedly connected with the water pumping impeller and drives the water pumping impeller to rotate forwards, and the second transmission mechanism is fixedly connected with the floating body and drives the floating body to rotate reversely. The oxygen aeration device is low in energy consumption, the floating body and the water pumping impeller achieve reverse rotation, the generated area of dome of water is increased, the water pumping and jetting capacity of the water pumping impeller is high, the dome of water is large, a water membrane is thin, and the oxygen dissolution effect is good due to contact with air, so that the oxygen content of water is raised as a whole, and a water circulating system of a fish pond is further improved through flowing of water.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an aeration device. Background technique [0002] The aerator is a machine used in fish farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water from threatening the living environment of the fish. At present, the impeller type aerator is widely used in the market. Its main advantages are simple structure and low price, but low efficiency and high energy consumption. The Chinese utility model patent with the authorized announcement number CN202729900U discloses an aeration device integrating rotary push wave and spray spray. The pumping impeller and the floating body are respectively driven to rotate through the reducer to generate a large area of ​​spray, but the produced spray is...
