Description

Technical Field

[0001] This utility model relates to the field of aeration equipment technology, and more specifically, to an aeration disc. Background Technology

[0002] An aeration disc is a device used in aquaculture and other fields. Its main function is to evenly diffuse air into the water to increase the dissolved oxygen content and meet the needs of biological treatment. The working principle of an aeration disc is to generate microbubbles, dissolving oxygen in the water to promote the growth of aquatic products. Its design typically includes a disc surface made of microporous material; these micropores ensure the formation and even distribution of bubbles in the water. Because aeration discs tend to accumulate dirt and easily clog the vents, frequent cleaning or replacement of the vent connectors is necessary, which is inconvenient and costly. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an aeration disc with a separate exhaust pipe that is easy to replace, thereby improving aeration efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an aeration disc, comprising a disc body, the disc body comprising multiple protrusions II, the disc body having a cavity, the protrusions II having channels II communicating with the cavity, the channels II penetrating the end of the protrusions II away from the disc body, the protrusions II being fitted with a sleeve, the outer wall of the end of the protrusions II away from the disc body having an insertion part, the insertion part being a ring-shaped oblique tooth and arranged in multiple layers along the axial direction of the protrusions II, the inner wall of the sleeve being elliptical, the minimum inner diameter of the sleeve being the same as the maximum outer diameter of the insertion part, the sleeve being fitted into the insertion part to form a snap-fit.

[0005] The present invention is further configured such that a channel is formed between the inner wall of the sleeve and the outer wall of the insertion part, and the channel and the hole are connected.

[0006] The present invention is further configured such that the outer wall of the sleeve is provided with a plurality of fine holes, which are connected to the channel.

[0007] The present invention is further configured such that the disc body also includes a protrusion, the protrusion having a channel, the channel communicating with the cavity.

[0008] The present invention is further configured such that a support rod is installed on the protrusion, and a first pipe clamp and a second pipe clamp are hinged to the outer wall of the support rod. The first pipe clamp can be engaged with the second pipe clamp, and the two surround each other to form a ring structure.

[0009] The present invention is further configured such that the first pipe clamp has a toothed part 1, and the second pipe clamp has multiple toothed parts 2, wherein the toothed part 1 is engaged with the toothed part 2 so that the first pipe clamp can be engaged with the second pipe clamp.

[0010] The present invention is further configured such that the hinge joint between the support rod and the first and second clamps is located on the side of the protrusion away from the disc.

[0011] The present invention is further configured such that the first channel is an air inlet and the second channel is an air outlet.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. The sleeve and the plug are connected and installed. The sleeve and the protrusion are two separate parts. When the fine holes of the sleeve are blocked and the air output effect is reduced, only the sleeve needs to be replaced. The sleeve is easy to replace and the replacement cost is low.

[0014] 2. Because the inner wall of the sleeve is elliptical and the outer wall of the insertion part is circular, a channel is formed between the inner wall of the sleeve and the outer wall of the insertion part. This channel is connected to the fine holes and orifices, allowing gas to be discharged through the fine holes on the sleeve located below the insertion part, thereby increasing the exhaust efficiency. At the same time, the top of the sleeve does not need to protrude too much from the top of the second protrusion, making the installation of the sleeve more stable and preventing it from easily detaching from the insertion part. The overall structure of the aeration disc is also smaller. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This embodiment discloses an aeration disc, such as Figure 1As shown, the aeration disc includes a disc body 1, which is a circular disc structure. The disc body 1 includes a protrusion 11 located at the center and multiple protrusions 13 evenly distributed along the circumferential axis of the disc body 1. Both the protrusion 11 and the protrusions 13 extend outward along the end face of the disc body 1 to form protrusions.

[0022] like Figure 3 As shown, the disc body 1 has a cavity 12, and the protrusion 11 has a channel 111. The channel 111 communicates with the cavity 12. The end of the channel 111 away from the cavity 12 passes through the protrusion 11. The channel 111 is an air inlet, and an air intake pipe can be inserted into the end of the channel 111 away from the cavity 12. Figure 2 The inner wall of the channel 111 is provided with a stepped surface 1111, and the end face of the air inlet pipe can abut against the stepped surface 1111 to form a seal.

[0023] like Figure 1 , Figure 2 As shown, convex body 11 is a ring structure. A support rod 112 is installed on the side wall of convex body 11. The axis of support rod 112 is parallel to the axis of convex body 11 and extends axially along the end face of convex body 11 away from the disk body 1. Pipe clamp 3 and pipe clamp 4 are hinged to the outer wall of support rod 112. The hinge point between support rod 112 and pipe clamp 3 and pipe clamp 4 is located on the side of convex body 11 away from the disk body 1. Pipe clamp 3 and pipe clamp 4 are both arc-shaped and metal parts. Pipe clamp 3 and pipe clamp 4 are both sheet-like and bendable. Pipe clamp 3 has a tooth 31, and pipe clamp 4 has multiple teeth 41. The tooth 31 engages with the teeth 41 to allow pipe clamp 3 to engage with pipe clamp 4, thus forming a ring structure and tightly wrapping the outer wall of the intake pipe inserted into the channel 111 to prevent the intake pipe from accidentally dislodging.

[0024] like Figure 3 As shown, the second protrusion 13 is provided with a second channel 131, which communicates with the cavity 12 and extends through the end of the second protrusion 13 away from the disk body 1. The outer wall of the end of the second protrusion 13 away from the disk body 1 is provided with an insertion part 132, which is a ring-shaped oblique tooth and is arranged in multiple layers along the axial direction of the second protrusion 13.

[0025] like Figure 3 , Figure 4 As shown, the second protrusion 13 is fitted with a sleeve 2. The outer wall of the sleeve 2 is provided with multiple fine holes, which are distributed on the outer wall of the sleeve 2. The second channel 131 is an air outlet, which is connected to the fine holes so that the gas entering the cavity 12 can be discharged from the fine holes on the outer wall of the sleeve 2 to oxygenate the water pool outside the aeration plate.

[0026] The inner wall of the sleeve 2 is elliptical, and the minimum inner diameter of the sleeve 2 is the same as the maximum outer diameter of the insertion part 132, so that the sleeve 2 forms a snap-fit ​​after being inserted into the insertion part 132. Furthermore, the sleeve 2 and the insertion part 132 are easy to install. The sleeve 2 and the protrusion 13 are set separately. When the fine hole of the sleeve 2 is blocked, causing the air output effect to decrease, only the sleeve 2 needs to be replaced.

[0027] like Figure 3 , Figure 4 As shown, since the inner wall of the sleeve 2 is elliptical and the outer wall of the insertion part 132 is circular, a channel 5 is formed between the inner wall of the sleeve 2 and the outer wall of the insertion part 132. The channel 5 is connected to the fine hole and the second channel 131, making... Figure 3 In the middle, the fine holes on the sleeve 2 located below the insertion part 132 can also discharge gas, thereby increasing the exhaust efficiency. At the same time, the top of the sleeve 2 does not need to be too much higher than the top of the protrusion 13, making the installation of the sleeve 2 more stable, and the sleeve 2 is not easy to fall out of the insertion part 132. The overall structure of the aeration disc is also smaller.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
