In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides an aeration sedimentation tank, includes lid, aerator, outer wall, water inlet and delivery port, the middle part of lid is equipped with the aerator, the lid sets up in the top of outer wall, and both mutually support, the side of outer wall is located to the delivery port, the center of outer wall low side is located to the water inlet, still includes aeration auxiliary component, aeration auxiliary component's top is cylindrical, and the diameter at its middle part enlarges gradually, and its bottom is for using the hemisphere, hemispherical bottom is equipped with the through-hole, aeration auxiliary component top is provided with the flow partition board, the flow partition board is the annular, and the outside at aeration auxiliary component top is located to its cover.

Water with certain pressure passes through the water inlet and is flushed to the aerator, the water is contacted with the air of the aerator, and due to the mutual impact force of the water and the air, the air can be more dissolved into the water than the air can be in the ordinary condition, so that the air content in the water is increased; as shown in the water circulation diagram, water forms water circulation due to the structure of the aeration auxiliary component, the contact time of air and water is continuously increased, and the air content in the water is increased again.

Further, the aeration auxiliary component is provided with a cavity for accelerating circulation of water flow, and the cavity is provided with an auxiliary water circulation device.

Further, the auxiliary water circulation device is a propeller capable of rotating freely.

The auxiliary water circulation device slowly rotates through the water impulse and reaches a certain rotating speed, and the water circulation speed is increased due to the inertia impulse of the auxiliary water circulation device, so that the air content in the water is increased again, and the aeration efficiency is improved.

Furthermore, the bottom surface of the cover is provided with a flow baffle which is hollow and cylindrical, one end of the flow baffle is connected with the bottom surface of the cover, and the inner side surface of the other end of the flow baffle is provided with a groove for installing the flow baffle.

Because the flow baffle and the flow isolating plate of the cover are in a closed state, water continuously flows in through the water inlet, the water in the auxiliary water circulation device is continuously increased, and the mutual repulsion force of air molecules and water molecules is continuously reduced under the condition that the pressure of the water and the air is continuously increased, so that the air is more compatible with the water; and secondly, the auxiliary water circulating device accelerates the circulation of water continuously, so that the pressure at the top of the aeration auxiliary component is increased continuously, air is more favorably fused with water, and the air content in the water is increased.

Furthermore, the outer side of the top end of the outer wall is provided with a water outlet groove, the water outlet groove consists of an outer plate, the outer wall and a convex groove which is arranged on the bottom surface of the cover and is positioned on the outer edge, and the water outlet is arranged on the outer plate of the outer wall.

The water outlet is arranged at the joint of the outer wall and the cover, which is beneficial to forming a certain water pressure outside to increase the pressure in the aeration auxiliary component and is also beneficial to melting air in water to increase the air content in the water.
