Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated aeration device for sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for drainage into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Aeration in sewage treatment refers to the process of forcing air into sewage, allowing the sewage in the pool to contact with air and oxygenate, stirring the liquid, accelerating the transfer of oxygen in the air to the liquid, preventing suspended objects in the pool from sinking, and strengthening the contact between organic matter and microorganisms and dissolved oxygen in the pool, and oxidizing and decomposing organic matter in sewage.

[0003] At present, the aeration efficiency of many devices is low, and the oxygen exposed by the aeration device is not fully utilized. In the specific application process, it manifests as long aeration time, high energy consumption, and high operating costs, which not only wastes energy. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated aeration device for sewage treatment in order to solve the above-mentioned technical problems, so as to ensure the balance of aeration intensity on the entire plane and improve the aeration efficiency and quality.

[0005] In view of this, the present invention provides an integrated aeration device for sewage treatment, including a blower, an aeration main pipe, an aeration branch pipe, and an aerator. The blower is connected to the aeration main pipe, and a plurality of aeration branch pipes are connected along the length direction of the aeration main pipe. The aeration branch pipe is provided with a plurality of air outlets along the length direction, and an aerator is connected above each air outlet. The aperture of the air outlet gradually increases along the flow direction of the airflow in the aeration branch pipe.

[0006] In the present technical solution, the gas enters the aeration main pipe from the blower and is divided into each aeration branch pipe, and then enters the aerator from the air outlet of the aeration branch pipe and is discharged into the sewage. When the gas flows into the end of the aeration branch pipe, due to the long flow path in the aeration branch pipe, the flow resistance consumes more pressure, and the aperture of the air outlet is set larger, so that the gas at the end can fully overflow even when the pressure is not sufficient, thereby ensuring the balance of aeration intensity on the entire plane, and packaging aeration efficiency and quality.

[0007] Furthermore, along the flow direction of the airflow in the aeration branch pipe, the distance between the air outlet holes gradually decreases.

[0008] In the present technical solution, the number of the air outlet holes at the end of the aeration branch pipe is increased, so that the air outlet volume at the end can be guaranteed, the aeration intensity of the entire plane is balanced, and the aeration efficiency and quality are packaged.

[0009] Furthermore, one end of the aeration branch pipe away from the aeration main pipe is connected to the connecting pipe.

[0010] In this technical solution, the ends of the aeration branch pipes are interconnected, and the connecting pipes can recover the remaining gas in the aeration branch pipes, and then automatically distribute the recovered gas to the aeration branch pipes with lower pressure according to the air pressure at the ends of the aeration branch pipes, so as to better utilize and distribute the gas.

[0011] Furthermore, the aerator comprises a mounting seat, an aeration chamber and an aeration membrane. The mounting seat is fixedly mounted on the aeration branch pipe through a connecting structure, and the aeration membrane is covered with aeration holes.

[0012] Furthermore, a support plate is fixedly arranged below the aeration membrane. The support plate is arc-shaped and matches the shape of the aeration membrane. Air holes are provided on the support plate. The diameter of the air holes is larger than the diameter of the aeration holes.

[0013] In the technical solution, the impact plate can effectively resist a part of the impact force of the gas, thereby reducing the impact of the gas on the aeration membrane and reducing the damage to the aeration membrane.

[0014] Furthermore, an angle adjustment structure is provided between the aerator and the aeration branch pipe, and the angle adjustment structure is used to adjust the direction of the aerator.

[0015] Furthermore, the angle adjustment structure includes a spherical seat, which is fixedly connected to the mounting seat of the aerator, a plastic hose is connected to the spherical seat, a connecting seat is fixedly connected to the air outlet of the aeration branch pipe, the spherical seat is rotatably set on the connecting seat, one end of the plastic hose is connected to the air outlet and the other end extends to the aeration chamber.

[0016] In the technical solution, the angle adjustment structure can be used to make the aerators at the edge rotate toward the central aerator, so that the gas ejected by the aerators at the edge can be more fully utilized.

[0017] Furthermore, the plastic hose is a corrugated tube.

[0018] Furthermore, the aeration device also includes an ultrasonic cleaning device, and the ultrasonic cleaning device is used to clean impurities deposited in the aeration holes.

[0019] Furthermore, the ultrasonic cleaning device includes an ultrasonic generator and a vibrator. The ultrasonic generator is buried under the sewage pool, and the vibrator connected to the ultrasonic generator extends into the sewage pool.

[0020] In the present technical solution, the ultrasonic cleaning device can clean the impurities deposited in the aeration holes, reduce the replacement frequency of the aerator, and save costs.

[0021] The beneficial effects of the present invention are:

[0022] 1. The aperture of the air outlet is set larger, so that the gas at the end can fully overflow even when the pressure is not sufficient, thereby ensuring the balance of aeration intensity on the entire plane, packaging aeration efficiency and quality.

[0023] 2. The ends of the aeration branch pipes are interconnected, and the connecting pipes can recover the remaining gas in the aeration branch pipes, and then automatically distribute the recovered gas to the aeration branch pipes with lower pressure according to the air pressure at the ends of the aeration branch pipes, so as to better utilize and distribute the gas.

[0024] 3. The ultrasonic cleaning device can clean the impurities deposited in the aeration holes, reduce the replacement frequency of the aerator and save costs. BRIEF DESCRIPTION OF THE DRAWINGS
