A jet aeration device in a sewage treatment system

Abstract

This utility model relates to the field of aeration pipe technology, specifically a jet aeration device in a sewage treatment system, including an aeration pipe body and a telescopic mechanism located at the end of the aeration pipe body. The telescopic mechanism can prevent the aeration pipe body from being blocked. In use, after the jet aerator is started, the aerator pushes open the anti-blockage cover of the aeration port to continue aeration. When not in use, the cover of the aeration port blocks the spray port to prevent the aeration port from being blocked. The aeration ports of existing multi-jet aeration devices are soaked in water for a long time when not in use. Since most of the water areas that need aeration are sewage or black and smelly water with a lot of silt and impurities, the jet aeration pipe is prone to blockage. This design not only prevents silt and impurities in the water from blocking the aeration port when in use, but also effectively cleans the impurities around the aeration port, ensuring a good working environment around the aeration port.

Description

Technical Field

[0001] This utility model relates to the field of aeration pipe technology, specifically a jet aeration device in a sewage treatment system. Background Technology

[0002] Aerators are crucial equipment for aeration and oxygenation in water supply and drainage systems. Currently, the main aeration methods include mechanical aeration, blower aeration, and jet aeration. Among these, jet aeration is widely used in engineering due to its simple structure, high aeration efficiency, and low infrastructure investment. Jet aeration devices utilize jet diffusers to supply oxygen in the aeration tank. For sewage and black / odorous water, aeration devices are typically needed to dissolve oxygen in the water to ensure that microorganisms in the water can undergo oxidation reactions, thereby reducing the microbial content in the sewage. However, the nozzles of existing multi-jet aeration devices are often submerged in water for extended periods when not in use. Since most water bodies requiring aeration are sewage or black / odorous water with high levels of silt and impurities, the jet aeration pipes are prone to clogging. Therefore, we propose a jet aeration device for sewage treatment systems. Utility Model Content

[0003] The purpose of this invention is to provide a jet aeration device in a wastewater treatment system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a jet aeration device in a sewage treatment system, comprising an aeration pipe body; and a telescopic mechanism located at the end of the aeration pipe body, the telescopic mechanism being able to prevent the aeration pipe body from becoming blocked.

[0005] Preferably, the telescopic mechanism includes a sliding groove at the end of the aeration pipe body, a telescopic shell slidably connected inside the sliding groove, a telescopic member on the inner wall of the sliding groove that can slide the telescopic shell, and a reset member on the outer wall of the telescopic shell that can prevent the aeration pipe body from being blocked.

[0006] Preferably, the telescopic component includes multiple return springs fixedly connected to the inner wall and bottom of the sliding groove, each return spring having a base fixedly connected to the end away from the bottom of the sliding groove, the base being slidably connected to the sliding groove, an annular groove being formed on the inner wall of the telescopic shell near the base, and a sliding rod being fixedly connected to the end of the base near the telescopic shell, the sliding rod being slidably connected to the annular groove.

[0007] Preferably, the reset component includes multiple through holes on the outer wall of the telescopic shell, a baffle plate rotatably connected to the telescopic shell around each through hole, a rotating groove on the baffle plate near the outer wall of the telescopic shell, a rotating rod fixedly connected to the outer wall of the telescopic shell inside the rotating groove, the rotating rod rotatably connected to the rotating groove, a spiral spring fixedly connected to the outer wall of the rotating rod, and the end of the spiral spring away from the rotating rod fixedly connected to the inner wall of the rotating groove.

[0008] Preferably, a barrier cover is fixedly connected to the end of the telescopic shell away from the aeration pipe body, and the outer wall of the telescopic shell has a rotating component that can drive the telescopic shell to rotate.

[0009] Preferably, the rotating component includes multiple telescopic grooves opened on the outer wall of the telescopic shell, a fixed rod fixedly connected to the inner wall of the telescopic groove near the aeration pipe body, a second spiral spring fixedly connected to the periphery of the fixed rod, a rotating arm fixedly connected to the end of the spiral spring away from the fixed rod, the rotating arm being rotatably connected to the telescopic groove, a membrane fixedly connected to the end of the rotating arm near the telescopic groove, and the end of the membrane away from the rotating arm being fixedly connected to the inner wall of the telescopic groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: When this utility model is in use, after starting the jet aerator, the aerator opens the cover of the aeration port to prevent blockage, and continues the aeration work. When not in use, the cover of the aeration port blocks the spray nozzle to prevent the aeration port from being blocked. The aeration ports of existing multi-jet aeration devices are soaked in water for a long time when not in use. Since most of the water areas that need aeration are sewage or black and smelly water with a lot of silt and impurities, the jet aeration pipe is prone to blockage. This design not only prevents silt and impurities in the water from blocking the aeration port, but also effectively cleans the impurities around the aeration port, ensuring a good working environment around the aeration port.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 Please see Figure 1-5 This utility model provides a technical solution: a jet aeration device in a sewage treatment system, including an aeration pipe body 1 and a telescopic mechanism 2. The telescopic mechanism 2 is located at the end of the aeration pipe body 1 and can prevent the aeration pipe body 1 from being blocked. Since the jet aerator is placed in water for a long time, when it is not in use, the aeration pipe body 1 is easily blocked due to the large amount of impurities in the water. When the jet aerator is started, the jet aerator can spray the telescopic shell 3 at the end of the aeration pipe body 1 through the telescopic mechanism 2. When not in use, the telescopic shell 3 can retract into the aeration pipe body 1 to prevent the aeration pipe from being blocked.

[0015] The telescopic mechanism 2 includes a sliding groove 12 at the end of the aeration pipe body 1. A telescopic shell 3 is slidably connected to the sliding groove 12. The telescopic shell 3 and the inner wall of the sliding groove 12 have telescopic components 31 that can slide on the telescopic shell 3. The outer wall of the telescopic shell 3 has a reset component 32 that can prevent the aeration pipe body 1 from being blocked. The telescopic component 31 includes multiple reset springs 33 fixedly connected to the inner wall and bottom of the sliding groove 12. Each reset spring 33 has a base 34 fixedly connected to its end away from the bottom of the sliding groove 12. The base 34 is slidably connected to the sliding groove 12. An annular groove 35 is formed on the inner wall of the telescopic shell 3 near the base 34. A sliding rod 36 is fixedly connected to the end of the base 34 near the telescopic shell 3. The sliding rod 36 slides on the annular groove 35. The dynamic connection and reset component 32 includes multiple through holes 37 on the outer wall of the telescopic shell 3. Each through hole 37 is rotatably connected to the telescopic shell 3 with a baffle plate 38. A rotating groove 39 is formed at the end of the baffle plate 38 near the outer wall of the telescopic shell 3. A rotating rod 310 is fixedly connected to the outer wall of the telescopic shell 3 within the rotating groove 39. The rotating rod 310 is rotatably connected to the rotating groove 39. A spiral spring 311 is fixedly connected to the outer wall of the rotating rod 310. The end of the spiral spring 311 away from the rotating rod 310 is fixedly connected to the inner wall of the rotating groove 39. A baffle cover 312 is fixedly connected to the end of the telescopic shell 3 away from the aeration pipe body 1. The outer wall of the telescopic shell 3 has a rotating component 313 capable of driving the telescopic shell 3 to rotate. The rotating component 313 includes multiple through holes 37 on the outer wall of the telescopic shell 3. The telescopic trough 314 has a fixed rod 315 fixedly connected to the inner wall of the telescopic trough 314 near the aeration pipe body 1. A spiral spring 316 is fixedly connected to the periphery of the fixed rod 315. A rotating arm 317 is fixedly connected to the end of the spiral spring 316 away from the fixed rod 315. The rotating arm 317 is rotatably connected to the telescopic trough 314. A membrane 318 is fixedly connected to the end of the rotating arm 317 near the telescopic trough 314. The end of the membrane 318 away from the rotating arm 317 is fixedly connected to the inner wall of the telescopic trough 314. When the jet aerator is started, the jet aerator pushes out the barrier cover 312. The barrier cover 312 drives the telescopic shell 3 to slide in the sliding groove 12. The telescopic shell 3 slides the base 34 to the end of the sliding groove 12 and stops moving when it abuts against the sliding groove 12. The water-air mixture inside the aeration pipe body 1 is ejected through the through hole 37 on the outer wall of the telescopic shell 3. At this time, the baffle plate 38, which is rotatably connected to the outer wall of the telescopic shell 3 outside the through hole 37, rotates around the rotating rod 310. When the telescopic shell 3 slides out of the sliding groove 12, the rotating arm 317, which is rotatably connected to the telescopic groove 314 on the outer wall of the telescopic shell 3, rotates around the fixed rod 315. When the rotating arm 317 rotates, it unfolds the film 318. The water-air mixture ejected by the jet aerator blows the film 318. Because multiple films 318 are blown in one direction, the telescopic shell 3 rotates when the films 318 are blown. When the telescopic shell 3 rotates, the water-air mixture is sprayed all around the periphery of the telescopic shell 3, which plays a role in cleaning the silt around the aeration pipe body 1.A sliding rod 36, fixedly connected to one end of the base 34 near the telescopic shell 3, slides within an annular groove 35 on the inner wall of the telescopic shell 3. The sliding rod 36 limits the movement of the telescopic shell 3. When aeration stops, the baffle plate 38 surrounding the through hole 37 closes due to the pull of the vortex spring 311. The return spring 33 pulls the base 34 towards the bottom of the sliding groove 12, causing the telescopic shell 3 to retract into the sliding groove 12. As the telescopic shell 3 slides, the inner wall of the sliding groove 12 abuts against the rotating arm 317, pressing the rotating arm 317 into the telescopic groove 314. The membrane 318 and the rotating arm 317 retract into the telescopic groove 314, preventing silt and impurities in the water from entering the aeration pipe body 1 and causing blockage.

[0016] Example 2 like Figure 6 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the rotating arm 317 has multiple skeletons 4 near the telescopic groove 314. A membrane 318 is fixedly connected between each skeleton 4. The addition of skeletons 4 between the membranes 318 increases their toughness, preventing excessive force from the water jet aerator from tearing them. Furthermore, the addition of skeletons 4 prevents the membrane 318 from not fully retracting into the telescopic groove 314 when the rotating arm 317 retracts. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
