Embodiment 1

[0023] see Figure 1-3 , in an embodiment of the present invention, a swing-type aeration device for domestic sewage treatment, comprising a pool body 1, a fixed frame 2, a water injection pipe 3 and a drain pipe 4, the top of the pool body 1 is fixedly connected with a fixed frame 2, and the pool body A water injection pipe 3 is installed on the top of the water injection pipe 3, and a valve is installed on the water injection pipe 3, and sewage is injected into the pool body 1 through the water injection pipe 3, and a drain pipe 4 is installed under the side wall of the pool body 1, and a valve is installed on the drain pipe 4. The treated sewage can be discharged through the drainpipe 4, the lower surface of the fixed frame 2 is fixedly connected with the mounting frame 7, the inside of the fixed frame 2 is equipped with a drive shaft 5, and the left and right ends of the drive shaft 5 are connected to the side wall of the fixed frame 2 respectively. Rotationally connected,...

Embodiment 2

[0025] On the basis of Embodiment 1, a stirring shaft 8 runs through the mounting frame 7, the stirring shaft 8 is rotationally connected with the mounting frame 7, the upper end of the stirring shaft 8 is connected with the drive shaft 5 through a bevel gear set 9, and the lower end of the stirring shaft 8 Extending into the pool body 1, the lower end of the stirring shaft 8 is fixedly connected with the stirring plate 13, the stirring rod 14 is distributed on the lower surface of the stirring plate 13, and the defoaming needle 15 is distributed on the stirring rod 14, when the driving shaft 5 rotates, it drives the stirring The shaft 8 rotates, thereby driving the stirring plate 13 to rotate, using the stirring rod 14 to stir the sewage, the sewage is fully mixed with the air bubbles, and the larger air bubbles are cut into smaller air bubbles by the defoaming needle 15, so that the sewage can fully contact with the air, further improving Aeration efficiency.

Embodiment 1、 Embodiment 2

[0026] Combined with Embodiment 1 and Embodiment 2, the working principle of the present invention is: inject sewage into the tank body 1 through the water injection pipe 3, make the sewage flood the aeration plate 12, start the blower 16, and use the blower 16 to transport air to the aeration plate 19, and then discharge into the bottom sewage through the aeration head, aerate the bottom sewage, start the swing motor 20, drive the turntable 21 to rotate, and then drive the swing rod 18 to swing back and forth through the connecting rod 23, thereby driving the aeration plate 19 to swing back and forth , so that the air bubbles are more evenly discharged into the sewage, so that the air bubbles and sewage are mixed more evenly, and the driving motor 6 is started at the same time. Drive the aeration plate 12 to rotate, use the aeration plate 12 to raise the surface sewage, make the surface sewage fully contact with the air, aerate the surface sewage, when the driving shaft 5 rota...

Abstract

The invention relates to the field of environmental protection equipment, particularly to a swing type aeration device for domestic sewage treatment. The swing type aeration device comprises a pool body, a fixing frame, a water injection pipe and a water discharge pipe, wherein the top of the pool body is fixedly connected with the fixing frame, the lower surface of the fixing frame is fixedly connected with a mounting frame, a driving shaft is mounted in the fixing frame, a swing rod is hinged to the bottom of the pool body, the top of the swing rod is fixedly connected with an aeration disc,the side wall of the fixing frame is fixedly connected with an air blower, the bottom of the pool body is fixedly connected with a swing motor, a stirring shaft penetrates through the mounting frame,and the lower end of the stirring shaft is fixedly connected with a stirring plate. According to the invention, in an aeration process, the aeration disc swings back and forth so as to uniformly discharge bubbles into sewage, so that the bubbles and the sewage are mixed uniformly; and the aeration plate is driven by the driving motor to rotate, the surface layer sewage is lifted by the aeration plate to make the surface layer sewage completely contact air so as to carry out aeration on the surface layer sewage, and the sewage is stirred by the stirring rod so as to completely mix the sewage and the bubbles.

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 artificial introduction of air into the biochemical aeration tank through appropriate equipment to achieve the desired purpose. Aeration not only makes the liquid in the pool contact with air to oxygenate, but also accelerates the transfer of oxygen in the air to the liquid due to the agitation of the liquid, so as to complete the purpose of oxygenation; in addition, aeration also prevents the suspension of the pool from sinking and strengthens the organic matter in the pool. The purpose of contacting with microorganisms and dissolved oxygen is to ensure that the microorganisms in the pool can oxidize and decompose organic matter in sewage under the condition of sufficient dissolved oxygen. [0003] The existing aeration device has a single structure ...
