Description

Technical Field

[0001] This invention relates to the field of aeration tank technology, and more particularly to an aeration tank for wastewater treatment. Background Technology

[0002] Existing technologies, such as patent application CN217459003U (a liftable aeration mechanism for sewage treatment that is easy to maintain), propose a maintenance method by lifting the aeration device to the water surface for maintenance in order to overcome the problem of low maintenance efficiency in the aeration tank.

[0003] However, the problems are as follows: during maintenance, the entire aeration device is raised to the water surface, the aeration tank cannot continue aeration, and the sewage treatment process is interrupted; in addition, when only one or a few aeration discs in the aeration device have a problem, raising all the aeration devices to the water surface makes it impossible to carry out targeted maintenance operations, and workers need to conduct large-scale inspections; at the same time, during maintenance, workers do not have a place to stand and operate, and the entire aeration device must be moved to the ground for maintenance, which is cumbersome. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this invention provides a wastewater treatment aeration tank, comprising: an aeration tank; a connecting main pipe installed on the upper side of the aeration tank; several independent aeration pipe groups arranged in the aeration tank; the connecting main pipe connected to the aeration pipe groups via connecting hoses; a lifting component installed on the aeration tank for moving each aeration pipe group individually upward or downward; several inspection plates arranged on the upper side of the aeration tank; and when the aeration pipe groups move upward, workers can perform maintenance operations on one or more aeration pipe groups on the inspection plates.

[0005] More preferably, each aeration pipe group is equipped with several equidistant aeration discs. When air is supplied to the aeration pipe group, the air is evenly sprayed out from the aeration discs and diffused into the entire aeration tank water.

[0006] More preferably, the aeration disc is equipped with a check valve.

[0007] More preferably, the aeration pipe assembly and the maintenance plate are staggered.

[0008] More preferably, the lifting assembly includes multiple sets of linear push rods and a first connecting plate; the linear push rods are installed on the aeration tank, and the telescopic part of the linear push rods is fixedly connected to the first connecting plate; the lower side of the first connecting plate is fixedly connected to the aeration pipe assembly.

[0009] More preferably, a leakage observation pipe is connected to the end of the aeration pipe group.

[0010] More preferably, it also includes a cleaning component, with the aeration pipe assembly not in contact with the aeration tank; the cleaning component scrapes away the sludge deposited at the bottom of the aeration tank.

[0011] More preferably, the cleaning component includes a translation component, a second connecting plate, a scraper, and a connecting water pipe; the translation component is installed on the aeration tank and is arranged in a left-right orientation; the second connecting plate is fixedly connected to the moving part of the translation component; the scraper is fixedly connected to the bottom of the second connecting plate; the sludge deposited at the bottom of the aeration tank is scraped by moving the scraper; the bottom of the scraper has a water outlet hole, and the scraper is connected to the connecting water pipe, so that high-pressure water is sent into the scraper through the connecting water pipe and sprayed out from the water outlet hole to disperse the sludge deposited at the bottom of the aeration tank.

[0012] More preferably, several sets of flushing components are fixedly connected to the upper side of the scraper. Each flushing component has two flushing heads located on both sides of the aeration pipe assembly. The flushing heads have flushing holes facing the aeration disc.

[0013] More preferably, an ultrasonic sensor for detecting the number of bubbles ejected from the aeration disc is installed on the flushing head, and a flushing hole facing the ultrasonic sensor is provided on the flushing head.

[0014] The advantages of this invention are: by setting the aeration structure of the aeration tank as multiple sets of aeration pipe groups, when it is observed or detected that the aeration effect in a certain area of ​​the aeration tank deteriorates, only the aeration pipe group covering that area can be raised to the water surface for maintenance, while the other aeration pipe groups remain in the aeration tank and continue to work normally. This does not require interrupting the sewage treatment process of the aeration tank, and workers do not need to check and maintain all the aeration discs in the aeration tank.

[0015] During maintenance, workers can stand on the maintenance plate to directly perform maintenance operations on the aeration pipe assembly without having to move the aeration pipe assembly to the ground.

[0016] This invention addresses the problems of sludge deposition damaging the microbial environment, reduced aeration efficiency due to covering aeration discs, and the inconvenience of equipment maintenance and inspection caused by biofilm adhesion to aeration discs during aeration tank operation. By integrating a scraper, a high-pressure flushing structure, and an ultrasonic sensor, the invention uses a scraper to break up the sludge at the bottom of the tank and high-pressure water to assist in suspension. Simultaneously, high-pressure water is used to flush the aeration discs to prevent biofilm contamination. At the same time, the ultrasonic sensor detects the number of air bubbles in the aeration discs in real time to determine the working status and also realizes automatic cleaning of the sensor, effectively ensuring the stable operation of the aeration tank.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0027] Example 1: As Figures 1-8 As shown, a sewage treatment aeration tank includes an aeration tank 1, a connecting main pipe 2, an aeration pipe assembly 3, a lifting component 4, and a maintenance plate 5.

[0028] A main connecting pipe 2 is installed on the upper side of the aeration tank 1; several independent aeration pipe groups 3 are set in the aeration tank 1, which are arranged in a left-right orientation and are parallel to each other; the main connecting pipe 2 is connected to the aeration pipe groups 3 through connecting hoses 2a, and a switch valve is installed between the main connecting pipe 2 and each connecting hose 2a; a lifting component 4 is installed on the aeration tank 1 to drive each aeration pipe group 3 to move up or down individually; several inspection plates 5 are set on the upper side of the aeration tank 1; when the aeration pipe groups 3 move up, workers can perform maintenance operations on one or more aeration pipe groups 3 on the inspection plates 5.

[0029] Each aeration pipe group 3 is equipped with several equidistant aeration discs 3a. When air is supplied to the aeration pipe group 3, the air is evenly sprayed out from the aeration discs 3a and diffused into the entire aeration tank water body, realizing the oxygenation and stirring of the water body.

[0030] The aeration disc 3a is equipped with a check valve to prevent sewage backflow.

[0031] The aeration pipe assembly 3 and the inspection plate 5 are staggered. When the aeration pipe assembly 3 moves upward, the worker can inspect the aeration pipe assembly 3 through the gap on the front or back side of the inspection plate 5.

[0032] The lifting component 4 includes multiple sets of linear push rods 41 and a first connecting plate 42; the linear push rods 41 are installed on the aeration tank 1, and the telescopic part of the linear push rods 41 is fixedly connected to the first connecting plate 42; the lower side of the first connecting plate 42 is fixedly connected to the aeration pipe group 3.

[0033] Existing technologies, such as patent application CN217459003U (a liftable aeration mechanism for sewage treatment that is easy to maintain), propose a maintenance method by lifting the aeration device to the water surface for maintenance in order to overcome the problem of low maintenance efficiency in the aeration tank.

[0034] However, the problems are as follows: during maintenance, the entire aeration device is raised to the water surface, the aeration tank cannot continue aeration, and the sewage treatment process is interrupted; in addition, when only one or a few aeration discs in the aeration device have a problem, raising all the aeration devices to the water surface makes it impossible to carry out targeted maintenance operations, and workers need to conduct large-scale inspections; at the same time, during maintenance, workers do not have a place to stand and operate, and the entire aeration device must be moved to the ground for maintenance, which is cumbersome.

[0035] like Figures 1-6 As shown, during aeration, air is delivered to the main pipe 2 via the pump assembly, then enters the aeration pipe group 3 via the connecting hose 2a, and is then evenly sprayed from the aeration disc 3a and diffused throughout the water body of the aeration tank 1, thereby achieving oxygenation and stirring of the water body.

[0036] When a decrease in aeration efficiency is observed or detected in the aeration tank, the aeration pipe assembly 3 needs to be raised to the water surface for maintenance. Figures 4-6 As shown, the specific operation of lifting the aeration pipe group 3 is to control the extension part of the linear push rod 41 of the corresponding aeration pipe group 3 to push upward, thereby driving the first connecting plate 42 and the aeration pipe group 3 to move upward and leave the water surface of the aeration tank. After that, the worker can stand on the inspection plate 5 to directly carry out the inspection operation of the aeration pipe group 3.

[0037] It should be noted that by setting the aeration structure of the aeration tank 1 as multiple sets of aeration pipe groups 3, when it is observed or detected that the aeration effect in a certain area of ​​the aeration tank deteriorates, only the aeration pipe group 3 covering that area can be raised to the water surface for maintenance, while the other aeration pipe groups 3 remain in the aeration tank and work normally. In this way, the sewage treatment process of the aeration tank does not need to be interrupted, and workers do not need to check and maintain all the aeration discs in the aeration tank.

[0038] In addition, a leakage observation pipe 3b is connected to the end of the aeration pipe assembly 3. When a certain aeration disc 3a is completely damaged, causing sewage backflow, that is, sewage from the sewage tank leaks into the pipe fittings of the aeration pipe assembly 3, when the worker is inspecting the aeration pipe assembly 3, he can observe whether there is water in the transparent leakage observation pipe 3b to determine whether the aeration disc 3a is completely damaged (when sewage from the sewage tank leaks into the pipe fittings of the aeration pipe assembly 3, more detailed inspection and maintenance operations are required). The sewage can be drained away by removing the leakage observation pipe 3b.

[0039] Example 2: Based on Example 1, such as Figures 1-8 As shown, it also includes a cleaning component 6. The aeration pipe group 3 is not in contact with the aeration tank 1, that is, the aeration pipe group 3 is not in contact with the bottom of the aeration tank 1, and the two are 5cm-10cm apart. The cleaning component 6 scrapes the sludge deposited at the bottom of the aeration tank 1.

[0040] The cleaning component 6 includes a translation component 61, a second connecting plate 62, a scraper 63, and a connecting water pipe 64. The translation component 61 is installed on the aeration tank 1 and is arranged in a left-right orientation. The second connecting plate 62 is fixedly connected to the moving part of the translation component 61. The scraper 63 is fixedly connected to the bottom of the second connecting plate 62. The sludge deposited at the bottom of the aeration tank 1 is scraped by moving the scraper 63, so that the sludge is scattered in the water again and suspended in the water again by the air bubbles blown out by the aeration disc 3a. The scraper 63 has a water outlet at the bottom and is connected to the connecting water pipe 64. High-pressure water is sent into the scraper 63 through the connecting water pipe 64 and sprayed out from the water outlet to disperse the sludge deposited at the bottom of the aeration tank 1 and transfer the sludge upward to the working area of ​​the aeration disc 3a.

[0041] Several sets of flushing components 65 are fixedly connected to the upper side of the scraper 63. Each flushing component 65 has two flushing heads located on both sides of the aeration pipe group 3. The flushing heads have flushing holes facing the aeration disc 3a.

[0042] An ultrasonic sensor 66 is installed on the flushing head to detect the number of bubbles ejected from the aeration disc 3a, and a flushing hole is provided on the flushing head facing the ultrasonic sensor 66.

[0043] As the aeration tank operates, sludge will accumulate at the bottom. This will firstly disrupt the living and metabolic environment of aerobic microorganisms, and secondly cover the aeration discs at the bottom of the tank, causing a significant decrease in the efficiency of the aeration discs. At the same time, after prolonged use, the aeration discs will produce biofilm, which will affect the aeration effect.

[0044] To address this, the present invention includes a cleaning component 6. When a certain amount of sludge accumulates at the bottom of the aeration tank after a period of operation, such as... Figures 7-8 As shown, at this time, the moving part of the control translation component 61 drives the second connecting plate 62 and scraper 63 to move left or right at the bottom of the aeration tank 1. When the scraper 63 moves, the scraper 63 scrapes the sludge at the bottom of the aeration tank, causing the sludge to be scattered in the water again, and the bubbles blown out by the aeration disc 3a are suspended in the water again. Furthermore, high-pressure water can also be injected into the scraper 63 through the connecting water pipe 64 using a high-pressure water input device. Then the high-pressure water is sprayed out from the water outlet hole at the bottom of the scraper 63. The sprayed high-pressure water impacts the sludge at the bottom of the aeration tank, causing the sludge to be scattered and quickly transferred upward to the working area of ​​the aeration disc 3a.

[0045] Furthermore, after the aeration disc has been used for a long time, in order to avoid the formation of biofilm, while the scraper 63 scrapes the sludge, high-pressure water can be injected into the flushing component 65 at the same time, and then sprayed out from the flushing hole opened in the flushing head of the flushing component 65, acting on the aeration disc 3a to clean the surface of the aeration disc 3a and avoid the formation of biofilm.

[0046] Furthermore, the specific method for detecting the aeration effect of a certain area in the aeration tank mentioned in Example 1 is as follows: After each time the scraper 63 scrapes the sludge and the flushing component 65 washes the aeration disc 3a, the ultrasonic sensor 66 can be turned on. The ultrasonic sensor 66 faces the aeration disc 3a, and the ultrasonic sensor 66 detects the number of bubbles sprayed from the aeration disc 3a to determine whether the aeration disc 3a is in normal working condition. When there is an abnormality, the aeration pipe group 3 needs to be moved to the water surface for maintenance. At the same time, in order to avoid the formation of biofilm on the ultrasonic sensor 66, the ultrasonic sensor 66 will be flushed every time the flushing component 65 works to achieve self-cleaning.

[0047] The present invention addresses the problems of sludge deposition damaging the microbial environment during the operation of aeration tank 1, the decrease in aeration efficiency caused by covering the aeration discs 3a, and the inconvenience of equipment operation and maintenance due to the easy adhesion of biofilm to the aeration discs 3a. By integrating a scraper 63, a high-pressure flushing structure, and an ultrasonic sensor 66, the scraper 63 scrapes and disperses the sludge at the bottom of the tank, and high-pressure water impact assists in suspension. At the same time, high-pressure water is used to flush the aeration discs 3a to prevent biofilm contamination. Meanwhile, the ultrasonic sensor 66 detects the number of bubbles in the aeration discs 3a in real time to determine the working status and also realizes automatic cleaning of the sensor, effectively ensuring the stable operation of the aeration tank 1.
