Example Embodiment

[0022] Example 1

[0023] See Figure 1-3 In the embodiment of the present invention, a swing type aeration device for domestic sewage treatment includes a tank body 1, a fixed frame 2, a water injection pipe 3, and a drain pipe 4. The top of the tank body 1 is fixedly connected with a fixed frame 2, and the tank body A water injection pipe 3 is installed on the top of 1 and a valve is installed on the water injection pipe 3. The sewage is injected into the pool body 1 through the water injection pipe 3, 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 drain pipe 4. A mounting frame 7 is fixedly connected to the lower surface of the fixing frame 2. A drive shaft 5 is installed inside the fixing frame 2. The left and right ends of the drive shaft 5 are respectively connected to the side walls of the fixing frame 2 Rotation connection, the outer side wall of the fixing...

Example Embodiment

[0024] Example 2

[0025] On the basis of Example 1, a stirring shaft 8 penetrates through the mounting frame 7, and the stirring shaft 8 is rotatably connected with the mounting frame 7. The upper end of the stirring shaft 8 is connected to the drive shaft 5 through the bevel gear set 9 and the lower end of the stirring shaft 8 Extending into the tank body 1, the lower end of the stirring shaft 8 is fixedly connected with a stirring plate 13, and a stirring rod 14 is distributed on the lower surface of the stirring plate 13, and a defoaming needle 15 is distributed on the stirring rod 14. When the driving shaft 5 rotates, the stirring is driven The shaft 8 rotates, thereby driving the stirring plate 13 to rotate, the sewage is stirred by the stirring rod 14, and the sewage and bubbles are fully mixed, and the defoaming needle 15 is used to cut larger bubbles into smaller bubbles, so that the sewage and the air are fully contacted, and further improve Aeration efficiency.

Example

[0026] Combining 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 discharged into the bottom sewage through the aeration head to 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 bubbles are discharged into the sewage more evenly, so that the bubbles and the sewage are mixed more evenly. At the same time, the drive motor 6 is started. When the drive motor 6 is running, the drive shaft 5 can be driven to rotate, thereby driving the driven shaft 10 to rotate through the transmission belt 11, thereby Drive the aeration plate 12 to rotate, use the ...

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 ...
