Embodiment 1

[0020] see Figure 1-3 , in the embodiment of the present invention, a swing type aeration device for domestic sewage treatment, comprising a pool body 1, a fixed frame 2, an aeration disc 18 and a blower 25, the top of the pool body 1 is fixedly connected with a fixed frame 2, The top of fixed mount 2 is hinged swing lever 3, and the right side of swing lever 3 is equipped with swing mechanism, and swing mechanism comprises first motor 4, rotating disk 5, fixed rod 6 and swing link 7, and the first motor 4 and fixed mount 2 The top is fixedly connected, the shaft extension end of the first motor 4 is provided with a turntable 5, the surface of the turntable 5 is fixedly connected with a fixed rod 6, and the fixed rod 6 is provided with a swing connecting rod 7, which rotates with the fixed rod 6 Connect, the left end of the swing link 7 is hinged with the middle part of the swing link 3, start the first motor 4, drive the turntable 5 to rotate, thereby drive the swing link 3 ...

Embodiment 2

[0024] On the basis of Embodiment 1, a stirring mechanism is installed at the bottom of the pool body 1, the stirring mechanism includes a third motor 21, a transmission shaft 22, a gear 23 and a stirring rod 24, and the aeration disc 18 is sleeved with a ring gear 20, The bottom of the pool body 1 is fixedly connected with a third motor 21, the shaft end of the third motor 21 is fixedly connected with a transmission shaft 22, and the middle part of the transmission shaft 22 is provided with a gear 23, the gear 23 meshes with the ring gear 20, and the transmission shaft 22 The top of the tank is fixedly connected with a stirring rod 24. When the third motor 21 is running, it drives the transmission shaft 22 to rotate, and then drives the aeration disc 18 to rotate, so that the air bubbles are more evenly discharged into the sewage, and the bottom sewage is aerated. A water inlet pipe 27 is installed on the top, and a valve is installed on the water inlet pipe 27. Sewage is disc...

Embodiment 1、 Embodiment 2

[0025] Combined with Embodiment 1 and Embodiment 2, the working principle of the present invention is: sewage is injected into the pool body 1 through the water inlet pipe 27, the blower 25 is started, and the air is transported to the hollow shaft 10, and then passes through the exhaust holes on the surface of the aeration roller 11 discharge, aerate the sewage, and at the same time, use the blower 25 to transport the air to the aeration plate 18, and then discharge it into the bottom sewage through the aeration head, aerate the bottom sewage, start the first motor 4, and drive the turntable 5 to rotate , so that the swing link 7 drives the swing rod 3 to swing left and right, thereby driving the aeration roller 11 to swing left and right, expanding the aeration range, improving the aeration efficiency, starting the second motor 9, driving the aeration roller 11 to rotate, and making the air bubbles more uniform At the same time, when the swing rod 3 swings left and right, it ...

Abstract

The invention relates to the field of environmental protection equipment, in particular to an oscillating aeration device for sanitary sewage treatment. The oscillating aeration device comprises a pool body, a fixing frame, an aeration disc and an air blower, wherein the top of the pool body is fixedly connected with the fixing frame, the top of the fixing frame is hinged with an oscillating rod,the right side of the oscillating rod is provided with an oscillating mechanism, the lower end of the oscillating rod is fixedly connected with a mounting frame, the side wall of the mounting frame isfixedly connected with a second motor, a shaft stretch end of the second motor is fixedly connected with a hollow rotating shaft, an aeration roller sleeves the hollow rotating shaft, the bottom of the pool body is provided with an aeration shaft, the top end of the aeration shaft is fixedly connected with the aeration disc, and the bottom of the pool body is also provided with a stirring mechanism. The aeration roller and the aeration disc are used for aerating middle-layer sewage and bottom-layer sewage respectively; during aeration, the aeration roller swings from side to side, which enlarges the aeration range and improves the aeration efficiency; a stirring plate is used for stirring the sewage, so that the sewage is fully mixed with bubbles, thereby further improving the aeration efficiency.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a swing type aeration device for domestic sewage treatment. Background technique [0002] Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. In addition, aeration also has the purpose of preventing the suspension of the tank from sinking and strengthening the contact between the organic matter in the tank, microorganisms and dissolved oxygen. In this way, the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. In the activated sludge process of wastewater, the dissolved oxygen in the mixed liquid must be replenished by aeration. The aeration methods used in the activated sludge aeration tank can be divided into two categories: mainly blast aeration and mechanical aeration. ...
