Pump-free oxygen increasing device

Abstract

The invention discloses a pump-free oxygen increasing device comprising a water sucking and spraying mechanism, a motor, a frame, and floating balls. The motor is fixed on the frame. A motor shaft of the motor is connected with the water sucking and spraying mechanism. The floating balls are arranged at the bottom of the frame. Of the water sucking and spraying mechanism, the lower part of a tubular body is a water sucking part, the side wall of the tubular body is equipped with a plurality of hollow water spraying parts communicated with the water sucking part, the water spraying parts can spray water without pumps under the action of centrifugal force when a power mechanism runs at certain speed, the inner wall of the tubular body is provided with a plurality of drainage troughs which facilitate rising flow of liquid, and the power mechanism is fixed on the frame. The oxygen increasing device can be put in a pool. As the oxygen increasing device has no rotating blades, the workload and cost of later maintenance are low, and the oxygen increasing device can adapt to more working conditions. The device is provided with an automatic detection control device, so that the working ability can be timely adjusted according to different external conditions, and energy is saved.

Description

technical field [0001] The invention belongs to the field of aeration equipment, in particular to a pumpless aerator. Background technique [0002] Aquatic products need oxygen in aquaculture. When the solubility of oxygen in water is equal to 2 mg / L, the water will stink; generally, when the dissolved oxygen in water is less than 5 mg / L, organisms cannot survive. At present, two or three pump-type aerators are installed floatingly on the water surface of most fish ponds to increase the solubility of oxygen in the water body, so as to achieve the dissolved oxygen required for the normal growth of fish schools. The existing pump-type aerators, Most of them use vane pumps, and fish ponds usually have a lot of impurities and high microbial content, which is easy to block the pump, and the setting of the pump itself will increase the cost of oxygenation, and the service life is not long, resulting in high maintenance costs. Contents of the invention [0003] The purpose of th...
