Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and more specifically, to a modular aeration system. Background Technology

[0002] The aerobic tank is a crucial component of a wastewater treatment system, primarily responsible for organic matter degradation, nitrogen and phosphorus removal, dissolved oxygen supply, and the elimination of bacteria and viruses. The aerobic tank contains a large number of aerobic microorganisms that utilize oxygen to decompose organic matter into carbon dioxide and water, oxidize ammonia nitrogen into nitrate nitrogen, and convert phosphates in wastewater into insoluble precipitates. Appropriate aeration and agitation measures ensure sufficient dissolved oxygen levels in the wastewater, creating a favorable ecological environment that promotes the activity and degradation efficiency of aerobic microorganisms.

[0003] Dissolved oxygen level in aerobic tanks is a crucial parameter. In China, microporous aerators are commonly used for aeration in aerobic tanks. However, problems such as clogging and tearing of the aeration membrane are prone to occur during the use of microporous aerators, requiring timely replacement of damaged parts. Currently, the aerobic tank usually needs to be emptied during inspection and maintenance, which is time-consuming and labor-intensive. Utility Model Content

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figures 1 to 3As shown, this utility model discloses a modular aeration system, which includes an aerobic tank body 100, a counterweight frame 200, a gas pipeline 300, and an aerator 400. The counterweight frame 200 is slidably installed in the aerobic tank body 100 in a vertical direction. The counterweight frame 200 is composed of several channel steels 210 spliced ​​together, with the openings of the channel steels 210 facing upwards. Lifting arms 220 are provided on both sides of the counterweight frame 200, with the upper ends of the lifting arms 220 exposed at the upper end of the aerobic tank body 100. The gas pipeline 300 is provided with a main pipeline 310 and a branch pipeline 320, which are connected. The main pipeline 310 and the branch pipeline 320 are evenly distributed within the channel steels 210. At least one aerator 400 is provided, and the aerator 400 is connected to the branch pipeline 320 through a rectangular tee 410. Specifically, in this embodiment, the aerobic tank 100 serves as the foundation of the entire aeration system, and its internal space is used to accommodate the wastewater to be treated and the activated sludge mixture. The counterweight frame 200 is assembled from multiple sections of channel steel 210 to form an integral frame that can move vertically. The openings of the channel steel 210 face upwards, facilitating the arrangement and maintenance of the gas pipeline 300. Lifting arms 220 are fixed to both sides of the counterweight frame 200, with their upper ends extending outside the aerobic tank, facilitating manual or mechanical operation of raising and lowering the counterweight frame 200. In this embodiment, the lifting arms 220 are located at the upper end of the aerobic tank 100, which avoids contact between the mechanical equipment controlling the entire counterweight frame 200 and the liquid in the aerobic tank 100, thereby reducing the need for sealing devices. The gas pipeline 300 consists of a main pipeline 310 and branch pipelines 320, both embedded inside the channel steel 210. This not only effectively resists buoyancy but also forms an integrated modular structure, facilitating overall disassembly or lifting to the top of the aerobic tank 100 for maintenance. At least one aerator 400 is provided, connected to the branch pipeline 320 via a rectangular tee 410. The rectangular tee 410 can be inserted into the channel steel 210 to prevent the aerator 400 from rotating during operation. The aerator 400 directly injects air or other oxygen sources into the water, promoting biological reactions. This structural design allows for easy maintenance by simply lifting the configuration frame to the surface of the aerobic tank 100, eliminating the need to empty the tank. This facilitates routine maintenance and inspection by personnel.

[0033] In some embodiments of this utility model, a first air inlet pipe 330 and a second air inlet pipe 340 are respectively provided at diagonal positions of the gas pipeline 300, and the first air inlet pipe 330 and the second air inlet pipe 340 are respectively connected to the main pipeline 310. Specifically, in this embodiment, by providing the first air inlet pipe 330 and the second air inlet pipe 340 at diagonal positions of the gas pipeline 300, with the output ends of the first air inlet pipe 330 and the second air inlet pipe 340 respectively connected to the main gas pipeline 300, and the input ends of the first air inlet pipe 330 and the second air inlet pipe 340 respectively connected to the gas source, a dual air inlet mode is formed, providing an additional air supply path. This not only enhances the aeration effect but also effectively prevents the problem of uneven gas supply caused by blockage at a single point. The dual air inlet strategy can significantly improve the dispersion of gas throughout the entire aerobic tank 100, avoid insufficient aeration in local areas, and ensure that all areas receive sufficient oxygen supply.

[0034] In some embodiments of this utility model, a pressure relief valve 350 is provided on the branch pipe 320. By providing a pressure relief valve 350 on the branch pipe 320, when the gas pressure in the branch pipe 320 exceeds a set threshold, the pressure can be quickly released through the pressure relief valve 350, thereby protecting the entire gas pipeline 300 and extending the service life of the gas pipeline 300.

[0035] In some embodiments of this utility model, multiple inverted U-shaped brackets 230 are provided on the counterweight frame 200 and the channel steel 210 to fix the gas pipe 300 inside the channel steel 210. In this embodiment, the inverted U-shaped brackets 230 can hold the gas pipe 300 and fix it on the channel steel 210, making the gas pipe 300 and the counterweight frame an integrated structure. This avoids displacement or damage caused by vibration or external force.

[0036] In some embodiments of this utility model, guide rods 110 and lifting mechanisms 500 are respectively provided on both sides of the aerobic pool body 100. The guide rods 110 and lifting arms 220 are slidably connected, and the lifting mechanism 500 is used to control the counterweight frame 200 to slide along the length direction of the guide rods 110. In this embodiment, by providing guide rods 110 on both sides of the aerobic pool body 100, the transmission mechanism and guide mechanism of the counterweight frame 200 can be avoided from being located in the aerobic pool body 100, thereby reducing the frequency of inspection and maintenance. Furthermore, by providing the lifting mechanism 500, the lifting arm 220 can be controlled to move in the vertical direction, thereby lifting the counterweight frame 200 and the gas pipeline 300 together upward and away from the horizontal, thus facilitating inspection and maintenance by personnel.

[0037] In some embodiments of this utility model, the lifting mechanism 500 includes a lifting base 510, a first lifting arm 520 / 520, a second lifting arm 530, a third lifting arm 540, a fourth lifting arm 550, a first rotating shaft 560, a second rotating shaft 570, a drive rod 580, and a saddle seat 590. The lifting base 510 is detachably connected to the aerobic tank body 100. One end of the first lifting arm 520 / 520 and the second lifting arm 530 are respectively rotatably connected to the lifting base 510. The other end of the lifting arm 530 is rotatably connected to the first rotating shaft 560, and the other end of the second lifting arm 530 is rotatably connected to the second rotating shaft 570; one end of the drive rod 580 passes through the first rotating shaft 560 and is connected to the second rotating shaft 570; one end of the third lifting arm 540 is rotatably connected to the first rotating shaft 560, and the other end is rotatably connected to the saddle seat 590; one end of the fourth lifting arm 550 is rotatably connected to the second rotating shaft 570, and the other end is rotatably connected to the saddle seat 590; the saddle seat 590 and the lifting arm 220 are detachably connected. In this embodiment, one end of the drive rod 580 can be rotatably connected to the second rotating shaft 570, or it can be threadedly connected to the second rotating shaft 570. When the drive rod 580 is working, the relative distance between the first rotating shaft 560 and the second rotating shaft 570 is controlled by controlling the drive rod 580, thereby controlling the included angle between the first lifting arm 520 and the second lifting arm 530. It can be understood that the first lifting arm 520, the second lifting arm 530, the third lifting arm 540, and the fourth lifting arm 550 form a parallelogram structure. By controlling the relative distance between the first rotating shaft 560 and the second rotating shaft 570, the relative distance in the vertical direction between the lifting base 510 and the saddle seat 590 can be controlled, thereby realizing the overall lifting of the counterweight frame 200. In this embodiment, when one end of the drive rod 580 and the second rotating shaft 570 are rotatably connected, the drive rod 580 can be hydraulically driven.

[0038] In some embodiments of this utility model, an adjusting arm 571 is provided on the second rotating shaft 570, and the drive rod 580 is threadedly connected to the adjusting arm 571. In this embodiment, the adjusting arm 571 and the drive rod 580 are threadedly engaged. When external power, such as an electric motor or manual force, controls the rotation of the drive rod 580, a push-pull force will be generated radially according to the principle of the screw pair, controlling the relative distance between the first rotating shaft 560 and the second rotating shaft 570.

[0039] In some embodiments of this utility model, one end of the drive rod 580 is provided with an L-shaped rotating part 581. By providing the L-shaped rotating part 581, it is convenient to manually control the rotation of the drive rod 580.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
