Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aerator which is easy to maintain. Background Art

[0002] In the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool is in contact with the air and oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, prevent the suspended objects in the pool from sinking, strengthen the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, and oxidize and decompose the organic matter in the sewage. This process of forcing oxygenation into the sewage is called aeration. Patent No. CN202123013807.3 discloses an aeration device for a sewage treatment facility that is easy to maintain to solve the technical problems existing in the aeration device of the prior art. The aeration device includes an aeration main pipe connected to the air source of the fan, and the aeration main pipe is overlapped on one side edge of the length direction of the aeration tank. The aeration main pipe is arranged with secondary aeration pipes at intervals, and the secondary aeration pipe is detachably equipped with a first aeration mechanism and a second aeration mechanism at intervals, and the first aeration mechanism is in contact with the bottom of the aeration tank. However, although the above patent overlaps the aeration main pipe on the edge of the aeration tank during maintenance, which is convenient for installation and disassembly, the air supply mechanism still needs to be closed during the maintenance and disassembly process, which leads to aeration interruption and affects the equipment's sewage treatment efficiency. At the same time, disassembly through flanges is not only time-consuming and laborious, but also increases the work intensity of the staff and reduces the practicality of the equipment. The "aerator for water body treatment that is easy to maintain" disclosed by application number "CN202222071592.9" solves the problem that the air supply mechanism still needs to be closed during maintenance and disassembly, which leads to aeration interruption and affects the equipment's sewage treatment efficiency through a specific technical structure setting. However, the device still has some problems, such as: the vertical pipe and horizontal pipe used for aeration are normally placed in the aeration tank. When the aerator is not running, the debris in the sewage in the aeration tank will block the aeration nozzle, resulting in unsatisfactory aeration effect, requiring manual regular cleaning and maintenance, but this is too time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of the utility model is to provide an aerator that is easy to maintain, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aerator that is easy to maintain, comprising an aeration tank, a first diversion pipe and a second diversion pipe, a column is provided on one side of the external top surface of the aeration tank, a first diversion pipe is fixed inside the column, a rotating joint is connected to one side of the first diversion pipe, a second diversion pipe is connected to one side of the rotating joint, and the second diversion pipe is provided in the middle of the external top surface of the aeration tank, one end of the second diversion pipe is connected to the output end of the motor, and the motor is fixed on the other side of the external top surface of the aeration tank.

[0005] When using an aerator that is easy to maintain in the technical solution, the staff opens the first valve to transfer the sewage to be treated to the aeration tank through the sewage pipe, closes the first valve after transferring an appropriate amount, and starts the aerator body.

When the aerator body is not running, the staff starts the motor, and the motor rotates the second diversion pipe connected to the output end, and the four second diversion pipes will rise from the aeration tank in two groups of symmetrical rotations and be placed in a parallel state, so that the first aeration pipe and the second aeration pipe will leave the aeration tank and separate from the sewage, avoiding the debris in the sewage from clogging the aeration holes when aeration is not in progress.

[0006] Preferably, the outer surface of the motor is provided with a shell, and heat dissipation holes are provided on both sides of the shell. The installation of the shell allows the motor to be installed inside, providing an installation position and protection for it, and the opening of the heat dissipation holes allows the motor installed in the shell to dissipate heat outwards through here, providing a heat dissipation channel.

Through the cooperation of the aerator body and the connecting pipe, air for treating sewage through air aeration can be transported to the inside of the first shunt pipe, achieving the effect of outputting air.

[0009] Preferably, a sewage pipe is connected to the top of one end of the aeration tank, and a first valve is arranged in the middle of the sewage pipe. Through the cooperation of the first valve and the sewage pipe, the sewage to be treated can be transported to the inside of the aeration tank, achieving the effect of on-off transport.

[0010] Preferably, the bottom of the other end of the aeration tank is connected to a sewage pipe, and a second valve is arranged in the middle of the sewage pipe.

[0013] 1. The utility model utilizes a motor to rotate and drive the second shunt pipe, and the second shunt pipe is connected to the first shunt pipe through a rotary joint, so that the second shunt pipe can seal and transmit air with the first shunt pipe while rotating itself.
