A sewage aeration device facilitating cleaning of an aeration pipe

Abstract

This utility model discloses a sewage aeration device that facilitates the cleaning of aeration pipes. The aeration mechanism is activated to introduce gas into the aeration pipe body, and the gas is discharged into the aeration tank through the aeration holes. If aeration is prolonged, sewage seeps into the aeration tank through the aeration holes and calcifies on the inner wall of the aeration pipe body. In this case, a high-pressure pump is activated to introduce water into the water pipe. The water pipe supplies high-pressure water to the cleaning mechanism, which impacts the calcified dirt on the inner wall of the aeration pipe body. The high-pressure water output also allows for deep cleaning of the aeration holes. With the traction component collecting the traction rope, the cleaning mechanism impacts the inner wall of the aeration pipe body from all directions, pushing the impacted dirt and water to the drain head and expelling it from the aeration pipe body. This solves the technical problem of existing mechanisms being unable to reach the aeration holes in the aeration pipe body, resulting in incomplete cleaning of the aeration pipe body and affecting its aeration performance.

Description

Technical Field

[0001] This utility model relates to the field of wastewater aeration pipe cleaning technology, specifically to a wastewater aeration device that facilitates cleaning of aeration pipes. Background Technology

[0002] Typically, because aeration pipes operate continuously in wastewater aeration tanks, calcium and iron deposits, as well as biological sludge, easily clog the aeration holes. Regular cleaning is necessary to prevent uneven bubble distribution, reduced oxygen transfer efficiency, and compromised wastewater treatment performance. Clogs also increase blower load, raise energy consumption, and can even damage equipment. While chemical cleaning with formic acid can remove scale, restore aeration efficiency, extend equipment lifespan, and ensure stable system operation, it is ineffective for cleaning the multiple aeration holes located in the middle of the aeration pipe.

[0003] To address the aforementioned issues, existing technology, such as CN219670286U, discloses an aeration pipe with a cleaning structure. This structure employs a forward and reverse motor to drive a lead screw, which in turn drives a moving block to slide on the outer circumference of the lead screw. Scrapers on the upper and lower connecting rods connected to the moving block clean the inner wall of the aeration pipe. However, the lengths of the upper and lower connecting rods are limited. Even if the scrapers can clean the inner wall of the aeration pipe, they cannot reach the aeration holes, resulting in incomplete cleaning and affecting the aeration function of the pipe. Utility Model Content

[0004] The purpose of this invention is to provide a sewage aeration device that facilitates cleaning of aeration pipes, thereby solving the technical problem that existing mechanisms cannot reach the aeration holes in the aeration pipe body, resulting in incomplete cleaning of the aeration pipe body and affecting the aeration use of the aeration pipe.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A wastewater aeration device for easy cleaning of aeration pipes includes an aeration pipe body with multiple aeration holes on its top surface. A fixed box is located at one end of the aeration pipe body, and a high-pressure pump is mounted on the top surface of the fixed box. A first collection tray is located inside the fixed box, and a first drive motor is located behind the first collection tray. A water pipe is wound around the first collection tray. The output end of the high-pressure pump is connected to the input end of the water pipe. A cleaning mechanism is located inside the aeration pipe body and is connected to the water pipe. A drain head is located at the other end of the aeration pipe body, and an inflation mechanism is connected to the other end of the drain head. A traction component is connected inside the inflation mechanism, and the traction component is connected to the cleaning mechanism via a traction rope that passes sequentially through the drain head and the interior of the aeration pipe body.

[0007] A further technical solution is that the cleaning mechanism includes a wall scraper and a high-pressure nozzle. One side of the high-pressure nozzle is connected to the wall scraper through a short pipe. The wall scraper has a hollow interior, and the water pipe passes through the hollow interior and is connected to the short pipe. The high-pressure nozzle has multiple water spray holes.

[0008] A further technical solution is that an isolation block is provided on the inner wall of the aeration pipe body, and the isolation block is in contact with the scraping block.

[0009] A further technical solution is that a baffle is provided at the connection between the water pipe and the short pipe, and the baffle is embedded in the short pipe for tight connection.

[0010] A further technical solution is that the bottom of the drain head is provided with a drain outlet, the drain outlet is provided with an extension pipe, and the bottom end of the extension pipe is threadedly connected with a first sealing cap.

[0011] A further technical solution is that the inflation mechanism includes a horizontal pipe and a vertical pipe, the horizontal pipe is connected to the drain head, the top surface of the horizontal pipe is connected to the vertical pipe, and the traction component is provided on the side of the vertical pipe.

[0012] A further technical solution is that the right end of the horizontal tube is provided with a second sealing cap, and the front is provided with a sealing plate.

[0013] A further technical solution is that the vertical pipe has a built-in butterfly valve, and a manual handle is installed through the inner wall of the vertical pipe, with the butterfly valve and the manual handle being fixedly connected.

[0014] A further technical solution is that the traction assembly includes a second drive motor, a second collection disc is provided inside the horizontal tube, the traction rope is wound around the second collection disc, a rotating shaft is connected to the top surface of the second collection disc, the rotating shaft passes through the inner wall of the horizontal tube and is rotatably connected thereto, and the other end of the rotating shaft is fixedly connected to the output shaft of the second drive motor.

[0015] A further technical solution is that the bottom of the second drive motor is provided with a support rod, the bottom end of which is fixed to the top surface of the crossbar, and the top end is fixedly connected to the drive motor.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The aeration mechanism is activated to introduce gas into the aeration pipe body, and the gas is discharged into the aeration tank through the aeration holes. If aeration is prolonged, the inner wall of the aeration pipe body will become calcified due to sewage seeping into it through the aeration holes. In this case, a high-pressure pump needs to be activated to introduce water into the water pipe. The water pipe supplies high-pressure water to the cleaning mechanism, which then impacts the calcified dirt on the inner wall of the aeration pipe body. The high-pressure water output can also deeply clean the aeration holes. With the traction component collecting the traction rope, the cleaning mechanism impacts the inner wall of the aeration pipe body from all directions, and pushes the impacted dirt and water to the drain head to expel it from the aeration pipe body. This solves the technical problem that existing mechanisms cannot reach the aeration holes in the aeration pipe body, resulting in incomplete cleaning of the aeration pipe body and affecting the aeration of the aeration pipe.

[0018] 2. The first drive motor drives the first collection disc to wind around the water collection pipe, and the traction component winds around the traction rope to drive the cleaning mechanism to slide back and forth inside the aeration pipe, increasing the number of times the inner wall of the aeration pipe is cleaned and improving the cleaning effect.

Detailed Implementation

[0023] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0024] See Figures 1 to 3This utility model provides a sewage aeration device that facilitates cleaning of aeration pipes, including an aeration pipe body 1, a plurality of aeration holes 2 on the top surface of the aeration pipe body 1, a fixed box 3 at one end of the aeration pipe body 1, a high-pressure pump 4 on the top surface of the fixed box 3, a first collection tray 5 inside the fixed box 3, a first drive motor (not shown) behind the first collection tray 5, a water pipe 6 around the first collection tray 5, the output end of the high-pressure pump 4 connected to the input end of the water pipe 6, a cleaning mechanism inside the aeration pipe body 1 connected to the water pipe 6, a drain head 7 at the other end of the aeration pipe body 1, an inflation mechanism connected to the other end of the drain head 7, a traction component inside the inflation mechanism, and the traction component connected to the cleaning mechanism by passing through the drain head 7 and the interior of the aeration pipe body 1 in sequence via a traction rope 25.

[0025] In this embodiment, the high-pressure pump 4 can be a BFL-025 type high-pressure pump 4. The aeration pipe body 1 and the aeration head 2 are common technical knowledge known to those skilled in the art and are existing technologies.

[0026] Specifically, the aeration mechanism is activated to introduce gas into the aeration pipe body 1, and the gas is discharged into the aeration tank through the aeration holes 2. If the aeration is prolonged, the inner wall of the aeration pipe body 1 will become calcified due to sewage seeping into it through the aeration holes 2. In this case, the high-pressure pump 4 needs to be activated to introduce water into the water pipe 6. The water pipe 6 inputs high-pressure water to the cleaning mechanism, which impacts the calcified dirt on the inner wall of the aeration pipe body 1. The high-pressure water output can also deeply clean the aeration holes 2. With the traction component collecting the traction rope 25, the cleaning mechanism impacts the inner wall of the aeration pipe body 1 from all directions and pushes the impacted dirt and water to the drain head 7 to drive it out of the aeration pipe body 1. This solves the technical problem that the existing mechanism cannot reach the aeration holes 2 provided in the aeration pipe body, resulting in incomplete cleaning of the aeration pipe body and affecting the aeration of the aeration pipe.

[0027] In addition, the first drive motor drives the first collection plate 5 to wind around the water collection pipe 6, and the traction component winds around the traction rope 25 to drive the cleaning mechanism to slide back and forth in the aeration pipe body, increasing the number of times the inner wall of the aeration pipe body 1 is cleaned and improving the cleaning effect.

[0028] Preferably, the cleaning mechanism includes a wall scraper 8 and a high-pressure nozzle 9. One side of the high-pressure nozzle 9 is connected to the wall scraper 8 through a short pipe 10. The wall scraper 8 has a hollow core 11 inside. A water pipe 6 passes through the hollow core 11 and is connected to the short pipe 10. The high-pressure nozzle 9 is provided with multiple water spray holes 12.

[0029] It should be noted that the diameter of the scraper block 8 is fitted to the inner wall of the aeration pipe body 1, so that the scraper block 8 can scrape off the dirt and water that fall into the aeration pipe body 1 during the sliding process.

[0030] In this embodiment, high-pressure water input through water pipe 6 is sprayed out through multiple high-pressure spray holes 12 to impact and clean the inner wall of the aeration pipe body 1, washing off the dirt attached to the inner wall of the aeration pipe body 1. The scraper block 8 on the side of the high-pressure nozzle 9 pushes the washed-off dirt and falling water towards the drain head 7. If the aeration hole head 2 encounters the strong impact of the high-pressure nozzle 9, the dirt attached to its inner wall is also washed off, allowing the aeration hole head 2 to be thoroughly cleaned.

[0031] Preferably, the inner wall of the aeration pipe body 1 is provided with an isolation block 13, which is in contact with the wall scraping block 8.

[0032] In this embodiment, the isolation block 13 can isolate the scraper block 8 and the inner wall of the aeration pipe body 1, so as to avoid the scraper block 8 from being stuck to the aeration pipe body 1 for a long time and generating a large adhesive force, thus preventing the scraper block 8 from being separated from the side wall of the aeration pipe body 1.

[0033] Preferably, a baffle 14 is provided at the connection between the water pipe 6 and the short pipe 10, and the baffle 14 is embedded in the short pipe 10 for tight connection.

[0034] In this embodiment, the baffle 14 prevents the dirt and water impacted by the high-pressure nozzle 9 from entering the hollow 11 of the scraper block 8, making subsequent cleaning inconvenient.

[0035] Preferably, the drain head 7 has a drain outlet at the bottom, and the drain outlet has an extension pipe 15. The bottom end of the extension pipe 15 is threadedly connected to a first sealing cap 16.

[0036] In this embodiment, when cleaning the aeration pipe body 1, the first sealing cover 16 needs to be opened to allow the scraper block 8 to push the dirty water towards the drain outlet. When inflating, the first sealing cover 16 can be placed over the drain outlet to prevent air leakage.

[0037] Preferably, the inflation mechanism includes a horizontal pipe 17 and a vertical pipe 18. The horizontal pipe 17 is connected to the drain head 7, and its top surface is connected to the vertical pipe 18. A traction component is provided on the side of the vertical pipe 18.

[0038] In this embodiment, the horizontal pipe 17 is used to support the operation of the traction assembly, and also to prevent the dirty water pushed out by the scraper block 8 from spraying into the vertical pipe 18, thus avoiding the need for cleaning the vertical pipe 18 as well. Since the horizontal pipe 17 is relatively short, subsequent cleaning is convenient.

[0039] Preferably, the right end of the horizontal tube 17 is provided with a second sealing cap 19, and the front end is provided with a sealing plate 20.

[0040] In this embodiment, when cleaning the aeration pipe body 1, the second sealing cover 19 can be opened to facilitate the large-area discharge of odorous gases. During inflation, the second sealing cover 19 can be placed over the drain outlet to prevent air leakage. After cleaning the aeration pipe body 1, the sealing plate 20 can be opened, and the traction rope 25 can be pulled out for cleaning to prevent bacterial growth. After cleaning, it can be connected to the second collection tray 24. During inflation, the sealing plate 20 needs to be sealed over the horizontal pipe 17 to prevent air leakage.

[0041] Preferably, the vertical pipe 18 has a built-in butterfly valve 21, and a manual handle 22 is provided through the inner wall of the vertical pipe 18. The butterfly valve 21 is fixedly connected to the manual handle 22.

[0042] In this embodiment, during inflation, an external air pump is connected, and the butterfly valve 21 is opened by rotating the manual handle 22. The air pump inputs gas through the vertical pipe 18 and outputs gas from the aeration head 2 through the horizontal pipe 17 and the aeration pipe body 1, thus aerating the aeration tank. When the butterfly valve 21 is closed, the air pump is disconnected, and the butterfly valve 21 can prevent external objects from entering the interior of the vertical pipe 18.

[0043] Preferably, the traction assembly includes a second drive motor 23, a second collection tray 24 is provided inside the horizontal tube 17, a traction rope 25 is wound around the second collection tray 24, a rotating shaft 26 is connected to the top surface of the second collection tray 24, the rotating shaft 26 passes through the inner wall of the horizontal tube 17 and is rotatably connected thereto, and the other end of the rotating shaft 26 is fixedly connected to the output shaft of the second drive motor 23.

[0044] In this embodiment, the second drive motor 23 drives the rotating shaft 26 to rotate, and the rotating shaft 26 drives the second collection plate 24 to wind around the traction rope 25. The traction rope 25 pulls the high-pressure nozzle 9 toward the drain head 7, so that the scraper block 8 pushes the dirty water out of the aeration pipe body 1.

[0045] Preferably, the second drive motor 23 is provided with a support rod 27 at its bottom, the bottom end of the support rod 27 is fixed to the top surface of the crossbar, and the top end is fixedly connected to the drive motor.

[0046] In this embodiment, the second drive motor 23 is fixed to the top surface of the horizontal tube 17 by the support rod 27 to ensure that the second drive motor 23 can work normally.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
