Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, specifically a municipal sewage aeration device. Background Technology

[0002] In municipal wastewater treatment, aeration is a crucial step. Its main purpose is to provide sufficient dissolved oxygen to the wastewater to meet the needs of microbial metabolism and growth, thereby promoting the degradation of organic pollutants and nitrification of ammonia nitrogen. It is an important means to ensure the effectiveness of wastewater treatment. Traditional aeration devices usually adopt a fixed aeration method, which has certain limitations. The aeration range of fixed aeration devices is relatively limited, and the gas release point is relatively fixed, resulting in uneven gas distribution in the wastewater. This uneven gas distribution will reduce aeration efficiency, causing insufficient oxygen supply in some wastewater areas, affecting the activity of microorganisms and the wastewater treatment effect. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an aeration device for municipal sewage treatment, which solves the problem that traditional aeration devices usually adopt a fixed aeration method. Fixed aeration devices have a relatively limited aeration range and relatively fixed gas release points, resulting in uneven gas distribution in sewage. This uneven gas distribution will reduce aeration efficiency, causing insufficient oxygen supply in some sewage areas, affecting the activity of microorganisms and the sewage treatment effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a municipal sewage renovation aeration device, comprising a base plate, wherein the base plate is modularly designed, and a plurality of support frames are fixedly installed evenly and equidistantly on the top of the base plate, and an aeration chamber is fixedly connected to the top of the support frames. A drive assembly is provided on one side of the base plate, the drive assembly comprising a fixed bracket, a drive arm rotatably connected to the inner wall of the fixed bracket, a waterproof motor fixedly installed at the top center of the fixed bracket, the output end of the waterproof motor being connected to one end of the drive arm, and a transmission arm rotatably connected to the other end of the drive arm, the end of the transmission arm away from the drive arm being rotatably connected to the bottom center of the base plate.

[0005] As a further embodiment of this utility model: a plurality of mounting brackets are fixedly connected to the top of the base plate, and an aeration pipe is fixedly mounted on the base plate through the mounting brackets, with the extension portion of each aeration pipe connected to each aeration chamber.

[0006] As a further embodiment of this utility model: two limiting components are provided on both sides of the base plate, each limiting component including a limiting slide rail, and a limiting slide groove is formed between the inner walls of the limiting slide rail, and the limiting slide rail is slidably connected to a limiting slider through the limiting slide groove.

[0007] As a further embodiment of this utility model: both the limiting slide groove and the limiting slider are designed in the form of an I-beam, the length of the limiting slide rail is greater than that of the limiting slider, and the two limiting sliders in the two limiting components are respectively connected to the two ends of the base plate.

[0008] As a further embodiment of this utility model: two baffles are symmetrically fixedly connected to the top of the base plate at the connection point with each module, and the baffles are rectangular in design.

[0009] As a further embodiment of this utility model: one end of the aeration pipe is fixedly connected to a connecting hose, and the end of the connecting hose away from the aeration pipe is fixedly connected to an aeration pump.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This municipal sewage treatment aeration device, through the installation of a drive assembly, controls the rotation of the drive arm within a fixed bracket during the aeration process of sewage. The end of the drive arm, during rotation, pushes and pulls, causing the transmission arm to swing. One end of the transmission arm follows the rotation of the drive arm, while the other end rotates below the base plate, pulling the base plate and converting the rotation of the drive arm into linear motion of the base plate. This, in turn, drives the limiting sliders on both sides of the base plate to slide back and forth in the limiting grooves of the limiting slide rails. Simultaneously, it drives the aeration chamber and aeration pipe to continuously reciprocate. In this way, the aeration range of the aeration chamber can be expanded, allowing the gas to be more evenly distributed in the sewage, effectively improving the aeration effect of sewage treatment and enhancing the aeration efficiency and treatment capacity of the entire device. 2. This municipal sewage treatment aeration device, through the installation of an aeration chamber and a baffle plate, works as follows: During operation, the aeration pump delivers gas to the aeration pipe via a connecting hose. The gas then enters the aeration chamber through the aeration pipe and is released into the sewage. Simultaneously, as the bottom plate drives the aeration chamber and aeration pipe in reciprocating motion, the baffle plate also reciprocates, disturbing the water flow. This ensures that the gas is released smoothly and evenly into the sewage, enhancing the mixing effect between the gas and sewage and allowing for full contact between them. This results in more efficient aeration treatment and improves the quality and efficiency of sewage treatment. Attached Figure Description

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: a municipal sewage renovation aeration device, including a base plate 1. The base plate 1 is modularly designed. Two baffles 8 are symmetrically fixedly connected to the top of the base plate 1 at the connection point with each module. The baffles 8 are rectangular in design. Due to the presence of the baffles 8, during the reciprocating motion of the aeration chamber 3 and the aeration pipe 6 driven by the base plate 1, the baffles 8 move with the base plate 1, causing disturbance to the water flow, further promoting the full mixing of gas and sewage, and improving aeration efficiency. Several support frames 2 are evenly and equidistantly fixedly installed on the top of the base plate 1, and the aeration chamber 3 is fixedly connected on the top of the support frames 2. A drive assembly 4 is provided on one side of the base plate 1. The drive assembly 4 includes a fixed bracket 401, a drive arm 402 rotatably connected to the inner wall of the fixed bracket 401, and a waterproof motor 403 fixedly installed at the center of the top of the fixed bracket 401. The output end of the waterproof motor 403 is connected to one end of the drive arm 402, and a transmission arm 404 is rotatably connected to the other end of the drive arm 402. The end of the transmission arm 404 away from the drive arm 402 is rotatably connected to the center of the bottom of the base plate 1. Because of the drive assembly 4, the waterproof motor 403 in the drive assembly 4 controls the rotation of the drive arm 402, which drives the transmission arm 404 to swing by pushing and pulling. The transmission arm 404 then drives the base plate 1 to perform reciprocating linear motion. This power... The transmission method is not only efficient, but also drives the aeration chamber 3 to reciprocate, expanding the aeration range of the aeration chamber 3 and improving the aeration effect of sewage treatment. Several mounting brackets 5 are fixedly connected to the top of the bottom plate 1. Aeration pipes 6 are fixedly installed on the bottom plate 1 through the mounting brackets 5. The extension of each section of aeration pipe 6 is connected to each aeration chamber 3. One end of the aeration pipe 6 is fixedly connected to a connecting hose 9. The end of the connecting hose 9 away from the aeration pipe 6 is fixedly connected to an aeration pump 10. Because of the connecting hose 9, the use of the connecting hose 9 can adapt to the movement of the bottom plate 1, avoid damage to the connection or gas leakage caused by pipe stiffness, ensure the normal operation of the entire aeration system, and enable the aeration pump 10 to stably deliver gas to the aeration pipe 6. Two limiting components 7 are respectively provided on both sides of the base plate 1. The limiting component 7 includes a limiting slide rail 701, and a limiting groove 702 is formed between the inner walls of the limiting slide rail 701. The limiting slide rail 701 is slidably connected to the limiting slider 703 through the limiting groove 702. Both the limiting groove 702 and the limiting slider 703 are I-shaped designs. The length of the limiting slide rail 701 is greater than that of the limiting slider 703. The greater length of the limiting slide rail 701 than the limiting slider 703 can prevent the limiting slider 703 from disengaging during movement. The slide rail 701 ensures that the base plate 1 always runs along the predetermined trajectory during reciprocating motion, improving the reliability and safety of the device. The two limit sliders 703 in the two limit components 7 are respectively connected to the two ends of the base plate 1. Because of the limit components 7, during the reciprocating motion of the base plate 1, the limit sliders 703 at both ends slide in the two limit slide grooves 702 respectively, which can effectively limit the movement trajectory of the base plate 1, ensure that the base plate 1 remains stable during the movement, and avoid deviation or shaking.

[0014] The working principle of this utility model is as follows: When using this device, firstly, the aeration pump 10 is started. The aeration pump 10 delivers gas to the aeration pipe 6 through the connecting hose 9. The gas enters the aeration chamber 3 through the aeration pipe 6 and is released into the sewage. At the same time, the waterproof motor 403 is started, and its output end drives the drive arm 402 to rotate. During the rotation of the drive arm 402, its other end continuously pushes and pulls the transmission arm 404, causing the transmission arm 404 to swing. The transmission arm 404 transmits power to the bottom plate 1. During this process, the transmission arm 404 drives the drive arm 402... The rotation is converted into linear motion of the base plate 1, causing the base plate 1 to drive the limiting sliders 703 on both sides to slide back and forth in the limiting grooves 702 of the two limiting slide rails 701. When the base plate 1 moves, it drives the aeration chamber 3 and the aeration pipe 6 to move back and forth continuously, thereby expanding the aeration range of the aeration chamber 3 and making the gas evenly distributed in the sewage. At the same time, the baffle plate 8 above the base plate 1 moves back and forth continuously with the base plate 1, disturbing the water flow and enhancing the mixing effect of gas and sewage, thereby achieving efficient aeration treatment.
