Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an aeration pipe for wastewater treatment. Background Technology

[0002] When replacing the aeration pipes in a sewage tank, the system needs to be shut down. At this time, the sewage tank can no longer be aerated. Existing technologies, such as patent documents with publication numbers CN101585582B (Aeration pipe installation structure and replacement method) and CN119898890B (A device for accurately positioning aeration pipe and a method for replacing aeration pipe), provide some structures that can maintain the sewage tank's aeration during the replacement of aeration pipes. However, the replaced aeration pipes still cannot aerate, which leads to uneven aeration effect in the sewage tank.

[0003] Furthermore, in the aforementioned patent documents, the aeration pipe is a single pipe, which can only cover a small aeration range and has low aeration efficiency. Summary of the Invention

[0004] To overcome the shortcomings mentioned in the background art, this invention provides an aeration pipe for sewage treatment, including an aeration main pipe, a drive assembly, and aeration branch pipes. The aeration main pipe is a closed rectangle and is made of flexible tubing. Multiple aeration branch pipes are detachably connected to the aeration main pipe. The drive assembly drives the aeration main pipe to rotate, allowing the aeration branch pipes to move along rectangular tracks, enabling them to reach the bottom and surface of the sewage tank. The drive assembly is installed in the sewage tank. The aeration branch pipes located at the bottom of the sewage tank are controlled to connect with the aeration main pipe for aeration, while the aeration branch pipes not at the bottom are controlled to not connect with the aeration main pipe for aeration. Workers can repair or replace the aeration branch pipes located on the water surface at the edge of the sewage tank.

[0005] Preferably, the drive assembly includes a toothed belt, a drive rod, and a drive gear; the toothed belt is fixedly connected to the inner side of the aeration main pipe; the drive rod is installed on the sewage tank and is driven to rotate by a motor; the drive gear is fixedly connected to the drive rod and meshes with the toothed belt; the meshing of the drive gear drives the toothed belt to rotate, thereby driving the aeration main pipe to rotate; the two drive rods located at the bottom of the drive assembly are installed at the bottom of the sewage tank, and the two drive rods located at the top are installed on the water surface.

[0006] Preferably, it also includes a push-type self-locking water valve and a push-type rotary disc; a push-type self-locking water valve is provided at the connection between the aeration main pipe and the aeration branch pipe; the push-type self-locking water valve cycles between opening and closing each time it is pressed; push-type rotary discs are fixedly connected to the drive rods at the lower left and lower right; when the aeration branch pipe that is not at the bottom of the water reaches the bottom of the sewage tank through the drive rod at the lower left or lower right, the push-type self-locking water valve is pressed down by the push-type rotary disc on the drive rod, so that the push-type self-locking water valve is opened, allowing the aeration branch pipe to connect to the aeration main pipe for aeration; when the aeration branch pipe at the bottom of the water leaves the bottom of the sewage tank through the drive rod at the lower left or lower right, the push-type self-locking water valve is pressed down by the push-type rotary disc, so that the push-type self-locking water valve is closed, and the aeration branch pipe is not connected to the aeration main pipe.

[0007] Preferably, initially, the push-button self-locking water valve on the aeration branch pipe between the lower left and lower right drive rods is in the open state, while the push-button self-locking water valves on the other aeration branch pipes are in the closed state.

[0008] Preferably, it also includes an air supply pipe, which is connected to the aeration main pipe to supply air to the aeration main pipe; the drive component drives the aeration main pipe to rotate clockwise once and then counterclockwise once, and so on.

[0009] Preferably, it also includes baffles. Multiple baffles are provided on the outside of the aeration main pipe to limit the deviation of the air supply pipe. The connection between the air supply pipe and the aeration main pipe is provided with an angle. When the aeration main pipe rotates clockwise, the air supply pipe is gradually released and moves along with the outside of the aeration main pipe under the restriction of the baffles. When the aeration main pipe rotates counterclockwise, the air supply pipe is gradually retracted.

[0010] Preferably, a collection frame is detachably connected to the aeration branch pipe, and a central filter screen is provided in the middle of the collection frame, which divides the collection area of ​​the collection frame into two.

[0011] Preferably, a collection hopper is provided on the upper side of the sewage tank to collect sludge falling from the collection frame; a filter plate is provided at the bottom of the collection hopper to intercept large-particle sludge.

[0012] Preferably, a flushing device is installed on the sewage tank to flush the collection frame, and a bottom filter screen is provided at the bottom of the collection frame.

[0013] Preferably, the flushing element has nozzles tilted to the lower left and to the lower right; the nozzles flush the passing aeration branch pipes.

[0014] The beneficial effects are as follows: By setting up aeration branch pipes that can circulate along a rectangular track and using a push-button self-locking water valve, this invention enables maintenance or replacement of the aeration branch pipes without shutting down the system. Simultaneously, it ensures continuous aeration through branch pipes at the bottom of the wastewater tank, effectively solving the problems of interrupted and uneven aeration caused by the need to stop the system when replacing aeration pipes in traditional methods. Furthermore, the movable aeration branch pipes, combined with a sludge collection frame, can automatically scrape and transfer sludge from the tank bottom during aeration, achieving integrated aeration and sludge removal, improving aeration efficiency and treatment effect. The flushing components on the water surface provide self-cleaning for the aeration branch pipes, preventing clogging and biofilm growth, and extending the equipment's service life.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0023] When replacing the aeration pipes in a sewage tank, the system needs to be shut down. At this time, the sewage tank can no longer be aerated. Existing technologies, such as patent documents with publication numbers CN101585582B (Aeration pipe installation structure and replacement method) and CN119898890B (A device for accurately positioning aeration pipe and a method for replacing aeration pipe), provide some structures that can maintain the sewage tank's aeration during the replacement of aeration pipes. However, the replaced aeration pipes still cannot aerate, which leads to uneven aeration effect in the sewage tank.

[0024] Furthermore, in the aforementioned patent documents, the aeration pipe is a single pipe, which can only cover a small aeration range and has low aeration efficiency.

[0025] Example 1: As Figures 1-6 As shown, this invention provides an aeration pipe for sewage treatment, including an aeration main pipe 1, a drive assembly 2, and aeration branch pipes 3. The aeration main pipe 1 is a closed rectangle and is made of flexible tubing. Multiple aeration branch pipes 3 are detachably connected to the aeration main pipe 1 and are arranged perpendicularly to the aeration main pipe 1. By setting multiple aeration branch pipes 3, a larger aeration area in the sewage tank 100 can be covered. The drive assembly 2 drives the aeration main pipe 1 to rotate, allowing the aeration branch pipes 3 to move along a rectangular track, enabling the aeration branch pipes 3 to move to the bottom and surface of the sewage tank 100. The drive assembly 2 is installed in the sewage tank 100. The aeration branch pipes 3 located at the bottom of the sewage tank 100 are controlled to connect with the aeration main pipe 1 for aeration, while the aeration branch pipes 3 not located at the bottom are controlled not to connect with the aeration main pipe 1 for aeration. Workers can repair or replace the aeration branch pipes 3 located on the water surface at the bank of the sewage tank 100.

[0026] Preferably, the drive assembly 2 includes a toothed belt 21, a drive rod 22, and a drive gear 23; the toothed belt 21 is fixedly connected to the inner side of the aeration main pipe 1; the drive rod 22 is installed on the sewage tank 100, the drive rod 22 on the water surface is driven to rotate by a motor, and the drive rod 22 at the bottom of the water is driven to rotate passively; the drive gear 23 is fixedly connected to the drive rod 22, and the drive gear 23 meshes with the toothed belt 21; the meshing of the drive gear 23 drives the toothed belt 21 to rotate, thereby driving the aeration main pipe 1 to rotate; the two drive rods 22 at the bottom of the drive assembly 2 are installed at the bottom of the sewage tank 100, and the two drive rods 22 at the top are installed on the water surface.

[0027] Preferably, it also includes a push-button self-locking water valve 101 and a push-button rotary disc 102; a push-button self-locking water valve 101 is provided at the connection between the aeration main pipe 1 and the aeration branch pipe 3; the push-button self-locking water valve 101 cycles between opening and closing each time it is pressed. For example, the push-button self-locking water valve 101 opens when pressed for the first time and closes when pressed for the second time. The push-button self-locking water valve 101 can adopt the push-button self-locking structure disclosed in CN222067639U (push-button self-locking water valve) and CN119103356A (a push-button gas switch valve). Simply put, it can be compared to a push-button ballpoint pen. When pressed, the pen tip cycles between being exposed and retracted and is self-locking. This can be compared to the sealing structure of a valve body; a pressing disc 102 is fixedly connected to the lower left and lower right drive rods 22 (i.e., the two drive rods 22 located at the bottom of the water); when the aeration branch pipe 3, which is not at the bottom of the water, passes through the lower left or lower right drive rod 22 and comes to the bottom of the sewage tank 100, the pressing disc 102 on the drive rod 22 presses down on the pressing self-locking water valve 101, causing the pressing self-locking water valve 101 to open, allowing the aeration branch pipe 3 to connect to the aeration main pipe 1 for aeration; when the aeration branch pipe 3 at the bottom of the water passes through the lower left or lower right drive rod 22 and leaves the bottom of the sewage tank 100, the pressing disc 102 presses the pressing self-locking water valve 101, causing the pressing self-locking water valve 101 to close, and the aeration branch pipe 3 is not connected to the aeration main pipe 1.

[0028] Preferably, initially, the push-button self-locking water valve 101 on the aeration branch pipe 3 between the lower left and lower right drive rods 22 is in the open state, and the push-button self-locking water valve 101 on the other aeration branch pipes 3 is in the closed state.

[0029] Preferably, it also includes an air supply pipe 4, which is connected to the aeration main pipe 1, and air is supplied to the aeration main pipe 1 through the air supply pipe 4; the drive component 2 drives the aeration main pipe 1 to rotate clockwise once and then counterclockwise once, and so on.

[0030] like Figures 3-4 As shown, preferably, it also includes baffles 41. Multiple baffles 41 are provided on the outside of the aeration main pipe 1 to limit the deviation of the air supply pipe 4. The connection between the air supply pipe 4 and the aeration main pipe 1 is provided with a corner. When the aeration main pipe 1 rotates clockwise, the air supply pipe 4 is gradually released by the winding structure. Under the restriction of the baffles 41, the air supply pipe 4 moves along with the outside of the aeration main pipe 1. When the aeration main pipe 1 rotates counterclockwise, the air supply pipe 4 is gradually retracted by the winding structure.

[0031] like Figure 1As shown, when using the aeration pipe of the present invention, the two lower drive rods 22 in the drive assembly 2 are installed at the bottom of the sewage tank 100, and the two upper drive rods 22 are installed on the water surface. In this way, the aeration branch pipes 3 installed on the aeration main pipe 1 can be partially located at the bottom of the sewage tank 100 for aeration, and partially located on the water surface for cleaning, maintenance or replacement.

[0032] During aeration, air is supplied to the aeration main pipe 1 through the air supply pipe 4. Then, the air is sent from the aeration main pipe 1 to the connected aeration branch pipes 3 to aerate the sewage tank 100. Initially, the push-button self-locking water valve 101 on the aeration branch pipe 3 located at the bottom of the water (i.e., between the two drive rods 22 at the bottom of the water) is in the open state, while the push-button self-locking water valves 101 on the other aeration branch pipes 3 are in the closed state. In this way, only the aeration branch pipes 3 at the bottom of the water are connected to the aeration main pipe 1 for aeration, while the other aeration branch pipes 3 are not aerated, thus avoiding the aeration branch pipes 3 on the water surface from connecting to the aeration main pipe 1 to release air, reducing air pressure and wasting gas.

[0033] Furthermore, when a certain aeration branch pipe 3 has a problem and needs maintenance and replacement, the control drive component 2 is activated, causing the motor to drive the drive rod 22 and drive gear 23 to rotate, which in turn drives the gear 23 to mesh and drive the toothed belt 21 to rotate, thus driving the aeration main pipe 1 to rotate, allowing the aeration branch pipe 3 to move along a rectangular motion track. This allows the aeration branch pipe 3 located at the bottom of the water to be moved to the surface of the water, allowing workers to repair or replace the aeration branch pipe 3 on the bank of the sewage tank 100.

[0034] Furthermore, the present invention is equipped with a press-type self-locking water valve 101 and a press-type rotary disc 102. When the aeration main pipe 1 rotates and drives the aeration branch pipes 3 to move, when the aeration branch pipe 3 that is not at the bottom of the water reaches the bottom of the sewage tank 100 after passing the lower left or lower right drive rod 22, the press-type self-locking water valve 101 is pressed down by the press-type self-locking water valve 101, so that the press-type self-locking water valve 101 is opened, allowing the aeration branch pipe 3 to connect with the aeration main pipe 1 for aeration; when the aeration branch pipe 3 at the bottom of the water reaches the bottom of the sewage tank 100, .... When the aeration branch pipe 3 leaves the bottom of the sewage tank 100 via the lower left or lower right drive rod 22, the press turntable 102 presses the press-type self-locking water valve 101, causing the press-type self-locking water valve 101 to close, and the aeration branch pipe 3 is not connected to the aeration main pipe 1; in this way, the present invention can ensure that the aeration branch pipe 3 moved to the bottom of the water can still aerate normally while the worker replaces the aeration branch pipe 3 on the water surface, ensuring the continuity of aeration in the sewage tank and avoiding partial interruption of aeration affecting the uniformity of aeration.

[0035] Furthermore, the present invention includes a detachable collection frame 103 connected to the aeration branch pipe 3. During normal operation, the drive component 2 can drive the aeration main pipe 1 to rotate slowly in a reciprocating cycle, that is, drive the aeration main pipe 1 to rotate clockwise once and then counterclockwise once, and so on (of course, it can be more than just one rotation). When the aeration main pipe 1 rotates, it can drive the aeration branch pipe 3 to move, allowing the aeration branch pipe 3 to scrape off the sludge deposited at the bottom of the sewage tank 100 through the collection frame 103, and allowing the sludge in the collection frame 103 to move with the aeration branch pipe 3 to the water surface for collection and treatment. The collection frame 103 is provided with a central filter screen 103a in the middle, which divides the collection area of ​​the collection frame 103 into two parts. Thus, when the aeration main pipe 1 rotates clockwise and counterclockwise, the collection frame 103 can scrape off the sludge deposited at the bottom of the sewage tank 100 and rotate to the water surface for collection and treatment.

[0036] In addition, a collection hopper 201 is provided on the upper side of the sewage tank 100 to collect the sludge that falls into the collection frame 103; a filter plate 201a is provided at the bottom of the collection hopper 201 to intercept large-particle sludge.

[0037] A flushing component 202 is installed on the sewage tank 100 to flush the collection frame 103. A bottom filter screen 103b is provided at the bottom of the collection frame 103.

[0038] After the sludge is transferred to the water surface through the aeration branch pipe 3, it slides off the collection frame 103 and into the collection hopper 201 for collection because the side of the collection frame 103 is not covered. Of course, when the collection frame 103 passes through the flushing device 202, the flushing device 202 can also be used to flush the permeable bottom filter screen 103b, flushing all the sludge into the collection hopper 201. Further, after the sludge falls into the collection hopper 201, it is transferred to the filter plate 201a. Small-diameter sludge passes through the filter plate 201a and falls back into the sewage tank for aeration, while large-diameter sludge is collected in the collection hopper 201. Workers can then directly scoop out the sludge from the bank of the sewage tank 100.

[0039] Thus, by setting up a rectangular movable aeration branch pipe 3 and setting a collection frame 103 on the aeration branch pipe 3, the present invention can continuously collect the sludge deposited in the sewage tank, and either pour the sludge back into the sewage tank 100 from top to bottom for full aeration treatment, or collect the sludge in a location that is easy for workers to remove.

[0040] In addition, the flushing component 202 has nozzles that are tilted to the lower left and to the lower right; the nozzles flush the aeration branch pipes 3 to achieve self-cleaning of the aeration branch pipes 3. The aeration main pipe 1 continuously drives the aeration branch pipes 3 to move under the flushing component 202 for flushing, which can prevent the aeration branch pipes 3 from being blocked and growing biofilm, thereby improving the aeration effect of the aeration branch pipes 3 and extending the service life of the aeration branch pipes 3.

[0041] Of course, the liquid sprayed by the flushing component 202 can also be a pre-mixed agent that can directly act on the sludge to improve the efficiency of wastewater purification.

[0042] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
