Description

Technical Field

[0001] The utility model relates to the field of aeration discs, in particular to an aeration disc assembly. Background Art

[0002] The aeration plate is an aeration device used in sewage treatment projects. Its main function is to increase the oxygen content in sewage by aerating the water, thereby promoting the decomposition and degradation of pollutants by microorganisms to achieve the purpose of purifying sewage.

[0003] When the existing aeration plate is in use, gas is usually emitted from the top thereof, so that the gas is concentrated and sprayed upward, and is emitted out of the water body too quickly, which reduces the contact time with the water body and reduces the oxygenation effect.

[0004] In order to solve the above problems, an aeration plate assembly is proposed in the present application. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes an aeration plate assembly. The utility model is provided with a jet component so that the aeration plate body can rotate when spraying gas, disturbing the water, increasing the contact area with the water and the duration, thereby increasing the oxygen content in the water.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides an aeration plate assembly, including an aeration plate body, the bottom of which is fixedly connected to an air inlet pipe;

[0009] The outer periphery of the aeration disc body is provided with an injection component for injecting gas to drive the aeration disc body to rotate.

[0010] Preferably, the jetting member comprises an arc-shaped pipe, and the arc-shaped pipe is fixedly connected to the aeration disc body.

[0011] Preferably, a filter is fixedly installed at the exhaust end of the arc-shaped pipe.

[0012] Preferably, a mesh cover is fixedly mounted on the top of the aeration disc body.

[0013] Preferably, a guide plate is fixedly mounted on the mesh cover.

[0014] The above technical solution of the utility model has the following beneficial technical effects:

[0015] The air inlet pipe is connected to the air supply pipeline through a rotating joint. When air is supplied to the air inlet pipe, the gas enters the interior of the aeration disc body, and a part of it is ejected from the top of the aeration disc body, and a part of it is discharged from the arc tube, which plays a recoil effect, so that the aeration disc body can rotate, which can disturb the water body, increase the contact area and residence time, and increase the oxygenation effect. Under the action of the mesh cover, the gas emitted from the top of the aeration disc body is blocked, the contact time between the gas and the water body is increased, and the oxygenation effect is increased. At the same time, the mesh cover and the guide plate rotate, and the guide plate guides the water to the top of the aeration disc body, which also increases the contact effect with the gas.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] like Figure 1-2 As shown, an aeration plate assembly proposed by the utility model includes an aeration plate body 1, and an air inlet pipe 2 is fixedly connected to the bottom of the aeration plate body 1;

[0021] The outer periphery of the aeration disc body 1 is provided with a jetting member 3 for jetting gas to drive the aeration disc body 1 to rotate.

[0022] In an optional embodiment, the jetting member 3 includes an arc-shaped pipe 31 , and the arc-shaped pipe 31 is fixedly connected to the aeration disk body 1 .

[0023] It should be noted that there are two arc-shaped tubes 31 , and the two arc-shaped tubes 31 are symmetrically arranged about the rotation center.

[0024] In an optional embodiment, a filter screen 32 is fixedly installed at the exhaust end of the arc tube 31 .

[0025] It should be noted that the filter 32 plays a role in dispersing the ejected gas.

[0026] In an optional embodiment, a mesh cover 4 is fixedly mounted on the top of the aeration disc body 1 .

[0027] Furthermore, a guide plate 5 is fixedly mounted on the mesh cover 4 .

[0028] It should be noted that the guide plate 5 is an arc-shaped guide plate, there are multiple guide plates 5, and the multiple guide plates 5 are evenly distributed at equal intervals.

[0029] In the utility model, the air inlet pipe 2 is connected with the air supply pipeline through a rotary joint. When the air inlet pipe 2 is supplied with air, the gas enters the interior of the aeration disc body 1, a part of which is ejected from the top of the aeration disc body 1, and a part of which is discharged from the arc tube 31, which plays a role of recoil, so that the aeration disc body 1 can rotate, and the water body can be disturbed, the contact area and the residence time are increased, and the oxygenation effect is increased. Under the action of the mesh cover 4, the gas emitted from the top of the aeration disc body 1 is blocked, the contact time between the gas and the water body is increased, and the oxygenation effect is increased. At the same time, the mesh cover 4 and the guide plate 5 rotate, and the guide plate 5 guides the water to the top of the aeration disc body 1, which also increases the contact effect with the gas.
