Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to a fluid stratified air-lift pipe. Background Art

[0002] With the continuous development of industrial society, the problem of water pollution has become increasingly serious. At present, sewage needs to be treated before being discharged. During the sewage treatment process, it is often necessary to continuously transfer the sewage for different treatment steps. At this time, water is usually guided by a water pump, which requires the motor to operate continuously at a high power. When the number of motors required is large, the energy consumption is high, the installation is inconvenient, and the later maintenance cost is high. The air-lift pipe is a liquid conveying device designed based on the basic principle of a communicating vessel with compressed air as the power, and has been widely used in the field of sewage treatment. However, in the prior art, the inlet of the air-lift pipe is at the bottom of the entire device, and its position needs to be adjusted when different layers of water bodies need to be extracted, and the use process is relatively cumbersome.

[0003] Therefore, in view of the above technical problems, it is necessary to provide an improved air-lift pipe to solve the above problems.

[0004] The information disclosed in this background art section is only for enhancing the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an improved air-lift pipe for solving the problem of cumbersome adjustment steps when extracting water bodies at different heights.

[0006] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0007] The utility model provides a fluid stratified air-lift pipe, which includes a main pipe, a water outlet pipe, an air inlet pipe, and a water inlet pipe. The water outlet pipe is connected to the main pipe and includes a water outlet extending upward out of the liquid level; the air inlet pipe is installed at the bottom of the main pipe and extends into the main pipe; the water inlet pipe is detachably connected to one side of the main pipe, and the water inlet pipe is formed with a water inlet with adjustable height to extend to different liquid level heights.

[0008] In one or more embodiments of the utility model, the water inlet pipe is sleeved with a telescopic sleeve, and the water inlet is formed on the sleeve.

[0009] In one or more embodiments of the present utility model, the main pipe includes a tee pipe, which includes an axially penetrating single connection port and a second connection port, and a third connection port opened between the first connection port and the second connection port. The water outlet pipe and the air inlet pipe are respectively fixed to the first connection port and the second connection port, and the water inlet pipe is connected to the third connection port.

[0010] In one or more embodiments of the present utility model, a first flange is fixed to the second connection port, and a second flange that mates with the first flange is fixed to the air inlet pipe.

[0011] In one or more embodiments of the present utility model, a plurality of air outlet ports are opened at one end of the air inlet pipe away from the second flange.

[0012] In one or more embodiments of the present utility model, a plurality of rows of air outlet ports arranged circumferentially along the air inlet pipe are provided at one end of the air inlet pipe away from the second flange.

[0013] In one or more embodiments of the present utility model, a plurality of the rows of air outlet ports are equidistantly arranged at one end of the air inlet pipe away from the second flange.

[0014] In one or more embodiments of the present utility model, the air inlet pipe extends into the water outlet pipe.

[0015] In one or more embodiments of the present utility model, an L-shaped adapter pipe is provided at one end of the water outlet pipe away from the main pipe, and the water outlet forms one end of the adapter pipe away from the water outlet pipe.

[0016] In one or more embodiments of the present utility model, the water inlet pipe and / or the water outlet pipe includes a fixing member for fixing to the container wall.

[0017] Compared with the prior art, in the fluid stratified air-lift pipe of the present utility model, the position of the water inlet can be adjusted. Therefore, when extracting water bodies at different heights (especially the dirt near the water surface), only the position of the water outlet needs to be adjusted, without operating the main body of the air-lift pipe. Therefore, the operation steps are reduced, and the work efficiency and ease of use are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1-2 shown, the fluid stratified air lift pipe 100 in an embodiment of the present utility model includes a main body pipe 10, a water outlet pipe 20, a water inlet pipe 30, and an air inlet pipe 40. The water outlet pipe 20 is connected to the main body pipe 10 and includes a water outlet 21 extending upward out of the liquid surface. The air inlet pipe 40 is installed at the bottom of the main body pipe 10 and extends into the main body pipe 10. The water inlet pipe 30 is connected to the main body pipe 10 and includes a water inlet 301. Usually, the water inlet of the air lift pipe is set at the bottom of the pipe main body, and the position is relatively fixed, and only the liquid at a fixed height can be extracted. However, in the actual sewage treatment process, it may be necessary to extract the contaminants on the surface of the sewage. At this time, the position of the air lift pipe needs to be adjusted to operate. And the height of the water inlet 301 of the fluid stratified air lift pipe 100 in this embodiment is adjustable, so it can extend to different heights of the liquid to extract liquids at different heights. When it is necessary to extract the contaminants on the surface of the sewage, only the position of the water inlet 301 needs to be adjusted, without the need for the whole, thus improving the flexibility and convenience in use.

[0025] Specifically, the main body pipe 10 is a tee pipe, including a first connection port and a second connection port that are circumferentially penetrated, and a third connection port opened between the first connection port and the second connection port. The water outlet pipe 20 and the air inlet pipe 40 are respectively installed at the first connection port and the second connection port, and the water inlet pipe 30 is connected to the third connection port. A sleeve 31 is fixed at the other end of the water inlet pipe 30, and the sleeve 31 is telescopic. At this time, the water inlet 301 is formed at the end of the sleeve 31 away from the water inlet pipe 30. When the position needs to be adjusted, the sleeve 31 can be operated.

[0026] like Figure 1 As shown, a first flange 11 is fixed at the second connecting port of the main pipe 10, and a second flange 41 matching with the first flange is fixed on the air inlet pipe 40 accordingly. The two flanges cooperate to fix the air inlet pipe 40 to the main pipe 10, and at the same time, the liquid at the second connecting port can be prevented from flowing into the main pipe 10, thereby ensuring that only the liquid or dirt at the water inlet 301 can enter the main pipe 10.

[0027] Preferably, a plurality of air outlets 42 are provided at one end of the air inlet pipe 40 away from the second flange 41 to increase the air outlet volume and improve the sewage discharge effect.

[0028] Furthermore, the air outlets 42 are arranged in a regular pattern on the air inlet pipe 40, such as Figure 2 As shown, multiple air outlets 42 are arranged along the axial direction of the air inlet pipe 40 to form an air outlet row, and multiple air outlet rows are equidistantly arranged at one end of the air inlet pipe 40 to make the air outlet more uniform and improve the drainage or sewage discharge effect.

[0029] In one embodiment, one end of the air inlet pipe 40 extends into the water outlet pipe 20. Of course, the final extension position of the air inlet pipe 40 can be set as needed, and this embodiment is not limited thereto.

[0030] Preferably, a transfer pipe 21 is provided at one end of the water outlet pipe 20 exposed to the water surface. Figure 1 In the embodiment shown, the transfer tube 21 is an L-shaped tube, so that the final water outlet is arranged horizontally. Of course, other different shapes of transfer tubes 21 can also be selected to adjust the final water outlet direction, and this embodiment is not limited. It should be understood that adjusting the final water outlet direction is intended to prevent sewage or dirt from flowing back.

[0031] A fixing member 50 is provided on the water outlet pipe 20 and / or the water inlet pipe 40 for fixing the fluid stratification gas stripping pipe 100 to the container wall. The fixing member 50 may be, for example, Figure 1 The U-shaped strip shown is fixed to the container wall by bolts. By fixing to the container wall, the stability of the fluid stratification gas lift pipe 100 during operation can be improved to prevent gaps between the components due to shaking. Of course, the fixing member can also be in other shapes as long as it can fix the fluid stratification gas lift pipe 100 to the container wall, and this embodiment is not limited thereto.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
