Description

Technical Field

[0001] This utility model relates to the technical field of water treatment aeration devices, and in particular to an aeration device for sewage treatment. Background Technology

[0002] Aeration is a key technology in the wastewater treatment process. By introducing air into the wastewater, it provides the oxygen needed by microorganisms and promotes the biodegradation of organic matter. Aeration can not only improve the efficiency of wastewater treatment, but also improve the quality of effluent.

[0003] The existing announcement number is CN201914970U, entitled "A Wastewater Treatment Aeration Drainage Device," which consists of a vertically arranged air supply main pipe and a horizontally arranged aeration drain. The air supply main pipe is vertically arranged, with an elbow at its upper end connected by a valve and flange, and the lower end of the air supply main pipe connected to the horizontally arranged aeration drain. The aeration drain includes air supply branch pipes and several parallel aeration pipes. The air supply branch pipes are welded to and connected to the several aeration pipes. The walls of the aeration pipes are evenly provided with aeration holes. Its support frame not only fixes the entire aeration drainage device but also increases the weight of the entire aeration drainage device, allowing it to sink into the water tank by natural gravity. This prevents the aeration pipes from floating due to their low density or shaking due to the air blowing of the aerator, thus improving the working performance of the aeration device.

[0004] However, the aforementioned sewage treatment aeration device inserts the aeration pipe directly into the sewage tank, guiding air into the sewage tank to contact the sewage. Although there is a large amount of water in the sewage tank, in actual aeration operation, the sewage closer to the aeration pipe has more contact with oxygen, while the sewage farther away from the aeration pipe has less contact with oxygen, resulting in uneven sewage aeration. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes an aeration device for sewage treatment.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an aeration device for sewage treatment, including a support, a water suction component, and an aeration component. The support includes a mesh cylinder, which is vertically installed in a sewage tank. A water suction component is vertically installed at the top of the mesh cylinder. The water suction component includes a water suction pipe, which is vertically connected to and assembled on the top surface of the mesh cylinder. A suction pump is connected to and assembled on the water suction pipe. An aeration component is installed at the top of the water suction pipe. The aeration component includes an aeration cylinder, which has an opening at the top. A support is horizontally fixed at the top of the aeration cylinder. An air guide pipe is vertically fixed through the support and connected to and fixed to the air guide pipe. A spray cylinder is vertically fixed inside the aeration cylinder at the bottom end. Multiple nozzles are evenly connected and fixed on the outer wall of the spray cylinder.

[0007] As a preferred embodiment, a support is vertically fixed on the bottom surface of the mesh cylinder, and the support is fixed to the bottom surface of the sewage tank by fixing screws.

[0008] As a preferred option, both the top surface of the mesh cylinder and the bottom surface of the aeration cylinder are vertically connected and fixed with screw rings.

[0009] As a preferred embodiment, the water suction pipe has external threads on both the upper and lower sides of its outer circumference, and the external threads at the upper and lower ends of the water suction pipe are respectively connected to the threaded rings on the mesh cylinder and the aeration cylinder.

[0010] As a preferred option, multiple return cylinders are evenly and horizontally arranged on the upper part of the outer circumference of the aeration cylinder, and one end of each return cylinder is fixed to the aeration cylinder.

[0011] As a preferred embodiment, a return spray bar is horizontally connected and fixed at the other end of the return cylinder, and multiple spray bars are horizontally and vertically connected and fixed on the return spray bar.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When aerating sewage in a sewage tank, the two ends of the suction pipe on the suction component are connected and fixed to the mesh cylinder and the aeration cylinder respectively. The suction pump on the suction pipe of the suction component is started to drive the sewage in the sewage tank into the aeration cylinder. The air pump on the air guide pipe is started to drive the external air into the spray cylinder. The sprayed air contacts the sewage in the aeration cylinder. After aeration is completed, the sewage overflows and is discharged from the top of the aeration cylinder. The amount of sewage in the aeration cylinder is small, which can make the sewage come into uniform contact with oxygen and improve the uniformity of sewage aeration. Attached Figure Description
