Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment aeration device. Background Art

[0002] The sewage treatment aeration device is the core equipment in the sewage treatment process. It combines air and sewage in a specific way, significantly increasing the dissolved oxygen content in the sewage. This device can not only effectively promote the dissolution of oxygen in the air into the sewage, meeting the growth and metabolic needs of aerobic microorganisms, but also accelerate the oxidation and decomposition of organic matter, thereby reducing the chemical oxygen demand and biochemical oxygen demand in the sewage, and significantly improving the water quality.

[0003] Existing sewage treatment aeration devices generally have two aeration methods, namely air aeration and mechanical aeration. Existing air aeration devices usually perform aeration at fixed positions. The sewage aeration effect between the corners of the aeration tank and the aeration nozzles is poor, and it is difficult to aerate sewage at different depths. The mixing effect of oxygen and sewage is poor, and the aeration efficiency is low. Existing mechanical aeration devices are prone to causing the water inside the tank to flow regularly during the aeration process, resulting in poor aeration flexibility. In addition, there is a general lack of means to detect water quality, making it difficult for operators to observe the degree of sewage aeration treatment and unable to ensure the quality of water after aeration treatment. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a sewage treatment aeration device to solve the technical problems of the existing aeration devices in terms of poor aeration effect, flexibility, oxygen and sewage mixing effect, and aeration efficiency.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sewage treatment aeration device, comprising an aeration tank and an aeration mechanism, the aeration mechanism comprising a rotating column, an aerator being provided on the top of the rotating column, a slide being provided on the outer surface of the rotating column, a slider being connected to the interior of the slide via a rotating shaft, one end of the slider being connected to a bellows, an aeration nozzle being provided on the other end of the slider, a rotating rod being provided on the back of the aeration nozzle, fan blades being provided on the outer surface of the rotating rod, and a hydraulic rod being provided at the bottom of the slider.

[0006] By adopting the above technical solution, the rotating column enables the slider to rotate around it, thereby driving the slider and the aeration nozzle to perform circular motion in the aeration tank, achieving a more uniform aeration effect.

[0007] Furthermore, a plurality of the sliders are provided, and the sliders are evenly and equidistantly arranged in a circular array along the central axis of the rotating column, and a plurality of spray holes are provided on the outer surface of the aeration nozzle.

[0008] By adopting the above technical solution, the slider makes the aeration process more uniform and efficient. Each slider is connected to an aeration nozzle, so aeration can be performed at different positions at the same time, improving the treatment efficiency. The several nozzles opened on the aeration nozzle allow oxygen to be sprayed into the sewage in the form of smaller bubbles.

[0009] Furthermore, the interior of the aeration tank is rotatably connected to the rotating column via a turntable bearing, and a water inlet pipe and a water outlet pipe are provided on both sides of the aeration tank.

[0010] By adopting the above technical solution, the turntable bearing enables the rotating column to rotate freely in the aeration tank, thereby driving the slider and the aeration nozzle to perform circular motion.

[0011] Furthermore, the water inlet pipe is provided with a water inlet valve, and the water outlet pipe is provided with a water outlet valve.

[0012] By adopting the above technical solution, the water inlet valve can accurately control the amount of sewage entering the aeration tank, ensuring the stability and efficiency of the treatment process.

[0013] Furthermore, a water quality monitoring sensor is provided inside the water outlet pipe, and the water quality monitoring sensor is used to detect water quality.

[0014] By adopting the above technical solution, the water quality monitoring sensor can detect the water quality in the water pipe in real time and provide accurate water quality data, so that operators can understand the sewage treatment effect in a timely manner.

[0015] Furthermore, a splash plate is provided on the top of the aeration tank, and the splash plate is shaped like a trumpet.

[0016] By adopting the above technical solution, the trumpet-shaped splash plate can effectively prevent sewage from splashing out of the aeration tank during the aeration process, thereby keeping the working environment clean and hygienic.

[0017] Furthermore, the aeration tank is cylindrical in shape and is made of fiberglass.

[0018] By adopting the above technical solution, the cylindrical shape makes the aeration tank more efficient in space utilization. Compared with other shapes, the cylindrical shape can provide more uniform water flow and air flow distribution, which helps to improve the aeration effect.

[0019] Furthermore, the model of the water quality monitoring sensor is DX-W100-1.

[0020] By adopting the above technical solution, the DX-W100-1 water quality monitoring sensor has high precision and can accurately measure various indicators in sewage, such as dissolved oxygen, pH value, turbidity, etc., providing reliable data support for operators.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The utility model realizes efficient aeration treatment of sewage by providing an aeration mechanism. The aerator transports oxygen to the aeration nozzle through the rotating column and the bellows, and the nozzle sprays the oxygen to aerate the sewage. The thrust of the nozzle causes the rotating column to drive the slider to rotate, and then the fan blades to rotate, thereby enhancing the mixing effect of sewage and oxygen and improving the aeration efficiency. At the same time, the device also has a flexible adjustment function. The operator can adjust the height of the slider through the hydraulic rod, thereby realizing aeration treatment of sewage of different depths, further improving the treatment effect, improving the aeration efficiency and enhancing the treatment flexibility.

[0023] 2. The utility model is equipped with a water quality monitoring sensor. The built-in water quality monitoring sensor can detect the water quality indicators of sewage in real time and accurately, and provide accurate feedback to the operator, so that the operator can adjust the treatment strategy in time according to the changes in water quality, such as adjusting the aeration time and aeration volume, to ensure that the effluent quality meets the preset standards, thereby improving the efficiency and effect of sewage treatment and reducing the subsequent treatment costs and risks that may be caused by substandard water quality.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] Example 1:

[0032] A sewage treatment aeration device, such as Figure 1-Figure 4 As shown, it includes an aeration tank 1 and an aeration mechanism 3. The aeration mechanism 3 includes a rotating column 301. An aerator 302 is provided on the top of the rotating column 301. A slide groove 303 is provided on the outer surface of the rotating column 301. A slider 305 is rotatably connected to the inside of the slide groove 303 through a rotating shaft 304. One end of the slider 305 is connected to a bellows 306. The other end of the slider 305 is provided with an aeration nozzle 308. A rotating rod 309 is provided on the back of the aeration nozzle 308. Fan blades 310 are provided on the outer surface of the rotating rod 309. A hydraulic rod 307 is provided at the bottom of the slider 305. The rotating column 301 enables the slider 305 to rotate around it, thereby driving the slider 305 and the aeration nozzle 308 to perform a circular motion in the aeration tank 1 to achieve a more uniform aeration effect. The aerator 302 is a key component for providing power. It can compress air or oxygen and transport it to the aeration nozzle 308 through a pipeline to provide necessary oxygen for the aeration process.

[0033] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 There are several sliders 305, which are evenly arranged in a circular array along the central axis of the rotating column 301. The outer surface of the aeration nozzle 308 is provided with a plurality of nozzle holes. The sliders 305 make the aeration process more uniform and efficient. Each slider 305 is connected to an aeration nozzle 308, so that aeration can be performed at different positions at the same time, thereby improving the processing efficiency.

[0034] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The interior of the aeration tank 1 is rotatably connected to the rotating column 301 through a turntable bearing. An inlet pipe 4 and an outlet pipe 6 are provided on both sides of the aeration tank 1. The turntable bearing enables the rotating column 301 to rotate freely in the aeration tank 1, thereby driving the slider 305 and the aeration nozzle 308 to perform circular motion. The inlet pipe 4 allows sewage to easily enter the aeration tank, while the outlet pipe 6 is used to discharge the treated sewage.

[0035] See Figure 1 、 Figure 2 An inlet valve 5 is provided on the water inlet pipe 4, and an outlet valve 7 is provided on the water outlet pipe 6. The inlet valve 5 can accurately control the amount of sewage entering the aeration tank 1 to ensure the stability and efficiency of the treatment process. The outlet valve 7 can adjust the discharge amount of treated sewage to ensure that the outlet water quality is stable and meets the standards.

[0036] Example 2:

[0037] See Figure 2 、 Figure 4 A water quality monitoring sensor 8 is provided inside the outlet pipe 6. The water quality monitoring sensor 8 is used to detect the water quality. The water quality monitoring sensor 8 can detect the water quality in the outlet pipe in real time and provide accurate water quality data, so that the operator can understand the sewage treatment effect in a timely manner. According to the feedback from the water quality monitoring sensor 8, the operator can adjust the aeration time, aeration volume and other treatment parameters in time to ensure that the outlet water quality always meets the preset standards.

[0038] See Figure 1 、 Figure 2 A splash guard 2 is provided on the top of the aeration tank 1. The splash guard 2 is shaped like a trumpet. The trumpet-shaped splash guard 2 can effectively prevent sewage from splashing out of the aeration tank 1 during the aeration process, keeping the working environment clean and hygienic. The splash guard 2 can also prevent operators or equipment from being contaminated or damaged by sewage splashing, thereby improving the safety of the workplace.

[0039] See Figure 1 The aeration tank 1 is cylindrical in shape and is made of fiberglass. The cylindrical shape makes the aeration tank 1 more efficient in space utilization. Compared with other shapes, the cylindrical shape can provide more uniform water flow and air flow distribution, which helps to improve the aeration effect. The fiberglass material has excellent corrosion resistance and can resist the erosion of chemical substances in sewage for a long time, thereby extending the service life of the aeration tank 1.

[0040] See Figure 2 、 Figure 4 The model of the water quality monitoring sensor 8 is DX-W100-1. The DX-W100-1 water quality monitoring sensor 8 has high precision and can accurately measure various indicators in sewage, such as dissolved oxygen, pH value, turbidity, etc., providing reliable data support for operators. This model of sensor has a self-cleaning system and can maintain long-term stable operation in harsh sewage environments, reducing the failure rate.

[0041] The implementation principle of the present utility model is as follows: first, sewage is added to the aeration tank 1 through the water inlet pipe 4 by opening the water inlet valve 5, and then the aerator 302 performs aeration treatment in the aeration tank 1 through the internal pipe of the rotating column 301, the bellows 306, the internal pipe of the slider 305 and the aeration nozzle 308. Then, due to the push of the aeration nozzle 308, the rotating column 301 drives the slider 305 to rotate, and at the same time, the internal sewage flows along the inclined surface of the fan blade 310, causing the fan blade 310 to rotate to mix the sewage with oxygen. The operator can adjust the height of the slider 305 through the hydraulic rod 307 to complete the aeration treatment of sewage at different depths. At the same time, the operator can use the water quality monitoring sensor 8 to detect the water quality of the sewage in real time. When the water quality meets the standard, the outlet valve 7 can be opened to allow the sewage to flow to the subsequent treatment device through the outlet pipe 6.
