Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a water body aeration device for artificial wetland water body restoration. Background Art

[0002] An artificial wetland is a ground similar to a marshland built and controlled artificially. Sewage and sludge are controllably distributed onto the artificially built wetland. During the process of flowing in a certain direction, the sewage and sludge mainly utilize the triple synergistic effects of soil, artificial medium, plants, and microorganisms, namely physical, chemical, and biological effects, to treat the sewage and sludge.

[0003] One crucial aspect of an artificial wetland is aeration. By using an aeration device to forcibly introduce air into the sewage, the sewage in the tank comes into contact with the air for oxygenation, and the liquid is agitated to accelerate the transfer of oxygen in the air into the liquid, prevent the suspension in the tank from sinking, strengthen the contact between the organic matter in the tank, microorganisms, and dissolved oxygen, and oxidize and decompose the organic matter in the sewage. Most of the existing aeration devices are of the blast type, jet type, and surface aeration type. Such aeration methods mostly stir the water body in the artificial wetland to make it contact with the air, or inject air into the water body. Since the gas is lighter, the efficiency of the gas dissolving into the water body is relatively low, and the gas escapes before being fully dissolved into the water body. Therefore, it is necessary to design a water body aeration device for artificial wetland water body restoration that can fully dissolve oxygen into the water body before discharging.

One path passes through the filter basket and penetrates deep into the water inlet cavity, and the other path carries sundries and is discharged along the sewage discharge pipe.

[0009] Further, the structure of the filter basket is adapted to the water inlet cavity. A clamping ring adapted to the outer peripheral structure of the filter basket is provided on the inner wall of the water inlet cavity, and a flange adapted to be clamped with the clamping ring is provided on the outer periphery of the filter basket.

The housing 1 is provided with a water inlet pipe 16 communicating with the water inlet cavity 13 at the top and a water outlet pipe 17 communicating with the water outlet cavity 15 on the side wall. The water inlet stirrer 2 is installed on the inner wall of the water inlet pipe 16, the filter basket 3 is installed in the water inlet cavity 13 below the water inlet pipe 16, the first partition 11 is arranged between the water inlet cavity 13 and the mixing cavity 14, and a connecting pipe 18 communicating the water inlet cavity 13 and the mixing cavity 14 is provided. The aeration generator 4 is installed at the bottom of the mixing cavity 14, and the mixing stirrer 5 is installed in the mixing cavity 14. The second partition 12 is vertically arranged in the housing 1, and is provided with an inclined plate extending obliquely downward to the left. There is a certain distance between the inclined plate and the inner side wall of the housing to form a communication channel connecting the mixing cavity 13 and the water outlet cavity 14.

[0026] In this embodiment, both the water inlet agitator 2 and the mixing agitator 5 are provided with blades and rotating motors. The rotating motor drives the water inlet agitator 2 to rotate, thereby generating water flow.

[0027] Both the water inlet agitator 2 and the mixing agitator 5 are provided with mounting frames. Preferably, the mounting frames are in a frame structure adapted to their structures, and are then fixedly installed at their corresponding positions by bolts.

[0028] A filter screen cover 6 is hinged at the opening of the water inlet pipe 16 to block sundries in the water body. The fixing method of the filter screen cover 6 is not limited in this embodiment. It can be pressed on the opening of the water inlet pipe 16 by its own weight made of metal material, or fixed by setting fixing holes opposite to the water inlet pipe 16 and inserting and fitting bolts or pins.

[0029] A sewage discharge port 19 is opened on the side wall of the housing 1 on the side of the water inlet cavity 13. A sewage discharge pipe 31 communicating inside and outside is provided on the side wall of the filter basket 3. The sewage discharge pipe is installed at the sewage discharge port 19. The water body outside the housing 1 is introduced into the water inlet cavity 13 along the water inlet pipe 16 by the water inlet agitator 2. The water body entering the water inlet cavity 13 is first filtered by the filter basket 3 to block sundries. The water flow is divided into two paths. One path passes through the filter basket 3 and penetrates deep into the water inlet cavity 13, and the other path carries the sundries and discharges along the sewage discharge pipe 31, realizing the function of automatic sewage discharge to avoid blocking the water inlet cavity 13 and reducing the number of times of cleaning the filter basket 3.

The water body enters the mixing cavity 14 along the connecting pipe 18, and oxygen is generated by the aeration generator 4 and enters the mixing cavity 14. The mixing stirrer 5 fully mixes the oxygen and the water body. Subsequently, the water body mixed with oxygen enters the outlet water cavity 15 along the secondary partition plate 12, and finally the water body mixed with oxygen is discharged from the housing 1 along the outlet pipe 17, realizing an artificial wetland water body restoration water body aeration device that discharges the water body after fully dissolving oxygen in the water body.

[0036] The power of the inlet stirrer 2 and the mixing stirrer 5 in this embodiment is not limited in this embodiment and is set according to requirements.
