Description

Technical Field

[0001] This invention relates to the field of aeration treatment, and more particularly to an aeration head and its aeration device. Background Technology

[0002] Aeration devices are widely used in applications requiring gas-liquid mixing, such as aeration tanks in biological wastewater treatment. Typically, the aeration heads of these devices are fixed at the bottom of the liquid material (e.g., sludge and mixed liquor) to ensure thorough mixing of the aeration gas with the liquid. However, when aeration heads malfunction due to displacement, damage, blockage, or burial, it is often necessary to drain all the liquid material before maintenance personnel can descend to the bottom of the tank to repair and maintain the aeration heads. Such repairs are time-consuming, labor-intensive, and require shutting down the aeration tank. Therefore, improvements to aeration heads and devices are still needed to address these issues. Summary of the Invention

[0003] One object of the present invention is to provide an aeration head and aeration device thereof to solve the problems in the prior art. Specifically, the present invention provides the following technical solution.

[0005] Furthermore, the first connecting part is configured to prevent the guide rail from rotating about its length axis.

[0006] Furthermore, the air supply pipe of the aeration head is a retractable air supply pipe, a corrugated pipe, or a flexible hose.

[0007] Furthermore, the aeration head also includes a support foot for supporting the aeration head body to form a water inlet channel at the water inlet of the aeration head body.

[0008] Another aspect of the present invention provides an aeration device, including the aeration head and a guide rail connected to the aeration head via a first connecting portion, wherein the lower end of the guide rail is provided with a first limiting portion for causing the aeration head to move downward along the guide rail until it stops when it abuts the first limiting portion.

[0009] Furthermore, the aeration device also includes a support frame, and the upper end of the guide rail is provided with a second limiting part. The guide rail is connected to the support frame through the second limiting part between the first connecting part and the second limiting part in a manner that allows the guide rail to move along its length direction. The second limiting part is used to stop the guide rail when it moves downward until the second limiting part abuts against the second connecting part. One or more of the guide rails are connected to the same support frame in the same manner.

[0014] S100, the aeration device is lifted and moved to the position above the location in the aeration tank where the aeration device needs to be installed, so that the aeration head connected to the guide rail moves downward along the guide rail under the action of gravity until the first connecting part abuts against the first limiting part downward.

[0015] S200, the aeration device is placed vertically downward along the length of the guide rail into the aeration tank, so that the supporting foot of the aeration head body and the lower end of the guide rail each abut against the bottom of the aeration tank.

[0016] Furthermore, step S100 also includes causing the guide rail connected to the bracket to move downward under the action of gravity until the second limiting part abuts against the second connecting part.

Detailed Implementation

[0027] The following description, in conjunction with the accompanying drawings, further illustrates some embodiments of the present invention, but is not intended to limit the scope of protection of the present invention. The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-5 As shown, the aeration head of the present invention includes an aeration head body 1 and a first connecting portion 12 disposed on the outer wall of the aeration head body 1. The first connecting portion 12 is configured to cooperate with a guide rail to allow the aeration head 1 to move along the length direction of the guide rail 2. The length direction of the guide rail 2 is parallel to the vertical direction of the aeration head 1 when it is in the aeration state. The aeration head body can be any suitable aeration head in the art, such as aeration heads known in the prior art, preferably the counter-current multi-nozzle aeration head disclosed in Chinese Utility Model Patent Publication CN212609785U, the entire text of which is incorporated herein by reference.

[0029] In some cases, the first connecting part 12 can prevent the guide rail 2 from rotating about its length axis. For example, as Figure 2 As shown, when guide rail 2 is rod-shaped ( Figure 2 When shown in cross-section, the first connecting part 12 has a tubular inner cavity that accommodates the guide rail 2, and the cross-sections of the tubular inner cavity and the guide rail match each other and are not circular. For example, the cross-sections can be polygons such as triangles, quadrilaterals, pentagons, hexagons, or irregular shapes with protrusions or recesses in their outlines.

[0030] For example, such as Figure 3 As shown, when guide rail 2 is tubular ( Figure 3 When shown in cross-section, the first connecting part 12 has a guide head that can be accommodated in the inner cavity of the tubular guide rail 2, and the tubular guide rail 2 is provided with a slit along its length to allow the connecting rod connecting the first connecting part 12 and the aeration head body 1 to move along the slit.

[0031] In some cases, the air supply pipe of the aerator head is a retractable air supply pipe, such as a corrugated pipe or a flexible hose.

[0032] In some cases, the aeration head also includes a support foot for supporting the aeration head body 1 to form an inlet channel 15 at the inlet of the aeration head body 1.

[0033] like Figure 4 As shown, the aeration device of the present invention includes, as Figure 1 The aeration head shown is connected to the aeration head via a first connecting part 12. The lower end of the guide rail 2 is provided with a first limiting part 21 for causing the aeration head to move downward along the guide rail until it stops when it comes into contact with the first limiting part 21.

[0034] In the following cases, the aeration device further includes a bracket 32, and the upper end of the guide rail 2 is provided with a second limiting part 22. The guide rail 2 is connected to the bracket 32 ​​between the first connecting part 12 and the second limiting part 22 through a second connecting part 23 in a manner that allows the guide rail 2 to move along its length direction. The second limiting part 22 is used to stop the guide rail 2 when it moves downward until the second limiting part 22 abuts against the second connecting part 23.

[0035] In some cases, one or more of the guide rails 2 are connected to the same bracket 32 ​​in the same manner.

[0036] In some cases, the second connecting portion 23 is configured to prevent the guide rail 2 from rotating about its length axis. Preferably, the second connecting portion 23 has a similar or identical structure to the first connecting portion.

[0037] In some cases, the support 32 is part of an aeration pipe or aeration branch pipe for providing aeration gas.

[0038] like Figure 5 As shown, this application is as follows Figure 4 The aeration device shown can be quickly and conveniently installed at any suitable location within the aeration tank 4, even when a mixture still exists in the aeration tank 4, using the following method, wherein an aeration pipe 3 is already fixed above the aeration tank. Specifically, the method for installing the aeration device includes the following steps:

[0039] S100, Figure 4The bracket 32 ​​of the aeration device shown is fixedly connected to the lower part of the aeration branch pipe 31. The bracket 32 ​​can be connected to the aeration branch pipe 31 and become part of the aeration branch pipe 31. The aeration branch pipe 31 is connected to the aeration head body 1 through the air supply pipe 14. Then, the aeration device connected to the aeration branch pipe 31 is lifted by a lifting device such as a crane and moved to the position above the location in the aeration tank 4 where the aeration device needs to be installed. This causes the guide rail 2 connected to the bracket 32 ​​to move downward under the action of gravity until the second limiting part 22 abuts against the second connecting part 23. The aeration head body 1 connected to the guide rail 2 moves downward along the guide rail 2 under the action of gravity until the first connecting part 12 abuts against the first limiting part 21.

[0040] S200, the aeration device is placed vertically downward along the length of the guide rail 2 into the aeration tank 4, so that the support foot 13 of the aeration head body 1 and the lower end of the guide rail 2 respectively abut against the bottom of the aeration tank 4.

[0041] S300, the upper end of the aeration branch pipe 31 is fixedly connected to the aeration pipe 3 in a fluid communication manner, for example, through a flange connection.

[0042] Since both the guide rail 2 and the aeration head of this application can move vertically, it is advantageously possible to ensure that the aeration head reaches the bottom of the aeration tank. In particular, even if there are obstacles on the bottom of the aeration tank caused by damaged aeration equipment or fallen debris, the aeration device of this application can advantageously adapt to the terrain of the tank bottom, enabling the aeration head to reach a suitable position on the bottom and avoiding the need to adjust the length of the aeration branch pipe 31 at the installation site. Therefore, the aeration device of this application can be installed quickly and conveniently without the need to drain the mixed liquid from the aeration tank or remove obstacles from the bottom, thereby advantageously ensuring the continuous operation of the aeration tank.

[0043] In some cases, neither the first connecting part 12 nor the second connecting part 23 can rotate along the length of the guide rail 2. Therefore, when installing and using the above-mentioned aeration device, the aeration head will not rotate around the guide rail and be displaced, thus effectively ensuring the installation position accuracy of the aeration head.

[0044] In some cases, the support foot 13 can form a water inlet channel 15 between the bottom of the pool and the water inlet of the aeration head body, thereby effectively avoiding the phenomenon of the water inlet being blocked by the bottom of the pool and ensuring the distance between the aeration head and the bottom of the pool.

[0045] In some cases, two or more aeration devices can be connected to the lower part of the same aeration branch pipe 31, thereby forming a multi-tooth anchor at the lower part of the aeration branch pipe 31 with the lower end of the guide rail of each aeration device and the support foot of the aeration head as teeth. This effectively avoids positional drift of each aeration device due to aeration operation and other reasons, thus ensuring the positional accuracy of the aeration devices, avoiding the torsion and damage to the aeration branch pipe 31 and the aeration pipe 3 caused by drift, and improving the stability and reliability of the device.

[0046] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The embodiments and features described in these embodiments can be arbitrarily combined without conflict. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
