Aerator

Abstract

The invention discloses an aerator, which comprises an impeller, a water adjusting plate, a power device which is used for driving the impeller and the water adjusting plate, a transmission device which is connected with the power device, a connecting plate, a supporting rod and floaters; and the quantity of the floaters is at least two, and the floaters are mutually connected with each other through the connecting plate to form an annular structure; the connecting plate is respectively connected with the water adjusting plate and the supporting rod, and the water adjusting plate is connected with the transmission device through the supporting rod; and the impeller is installed under the water and 3 to 15cm away from the water surface. By adopting the aerator, the load of a motor can be alleviated, the service life of the motor can be prolonged, the effective aeration area can be enlarged while the electric energy is saved, the oxygen content under the water is increased, and the water quality is improved.

Description

technical field [0001] The invention relates to aquaculture equipment, in particular to an aerator. Background technique [0002] Aerator is a kind of oxygen increasing equipment used in aquaculture industry. It can increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic. It can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water from threatening the fish. living environment. [0003] There are many types of aerators, such as impeller type, waterwheel type, jet type, water spray type, inflatable type, etc. Among them, the impeller type aerator has the comprehensive functions of oxygenation, water stirring, and gas explosion, and is currently the most Oxygenator used. The power unit of the impeller type aerator in the prior art drives the impeller deep into the water to rotate at a high speed in the water, and the water is drawn out of the water surface and sprinkled into the ai...

Problems solved by technology

[0004] However, this type of impeller type aerator has three obvious disadvantages: (1) Since the water at the bottom of the water needs to be pumped out of the water surface, the impeller must be installed at the middle and lower depths of the fish pond, which will inevitably cause a large burden on the motor and consume electric energy. Happening

(2) Due to the design of the product structure, the water wheel aerator in the prior art cannot expand the effective aeration area

(3) The oxygenation effect of the water wheel type aerator in the prior art shows that the oxygen content at the bottom is far less than the oxygen content at the water surface. Oxygen or lack of oxygen will cause the head of fish and shrimp to float, and hypoxia will occur, resulting in the death of fish and shrimp
