Description
Technical Field
[0001] This application relates to the technical field of maintenance of aeration pipelines in biochemical aeration tanks, and specifically discloses a maintenance device for aeration pipelines in biochemical aeration tanks. Background Art
[0002] An aeration pipeline is a device for supplying oxygen to an aeration tank, mainly composed of an aeration pipeline connected to an aeration blower and aeration heads, and is mainly applied to various types of biochemical aeration tanks. A number of threaded posts for installing aeration heads are formed on the aeration pipeline, and air holes are formed through the threaded posts. The blower passes air into the biochemical aeration tank through the aeration pipeline and the aeration heads to achieve the purpose of oxygenation. At the same time, the oxygen in the air is accelerated to transfer into the liquid by agitating the liquid to complete the oxygenation function.
[0003] During the aeration process of the aeration pipeline, its surface is easily eroded. After the aeration pipeline is eroded, the oxygen supply effect of the biochemical aeration tank aeration pipeline device on the aeration tank will be reduced. The existing aeration pipeline maintenance device seals the aeration pipeline to be detected by putting it into a water tank and passes gas into the aeration pipeline to be detected. Whether the aeration pipeline to be detected leaks is judged by observing whether there are bubbles overflowing on the surface of the aeration pipeline. However, when the degree of erosion of the surface of the aeration pipeline to be detected is relatively small, during the process of passing gas into the aeration pipeline to be detected, the amount of gas leaked from the smaller gaps is less, and the generated bubbles may be discontinuous and too small in volume, making it difficult to observe, and the detection of the aeration pipeline will be inaccurate.
[0004] Therefore, in view of this, the inventor provides a maintenance device for aeration pipelines in biochemical aeration tanks to solve the above problems. Utility Model Content
[0005] The purpose of the present utility model is to solve the problem that in the existing aeration pipeline maintenance device, when the degree of erosion of the aeration pipeline is small, during the process of passing gas into the aeration pipeline to be detected, the amount of gas leaked from the smaller gaps is less, the generated bubbles may be discontinuous and too small in volume, making it difficult to observe, and the detection of the aeration pipeline will be inaccurate.
[0006] To achieve the above purpose, the basic scheme of the present utility model provides a maintenance device for aeration pipelines in biochemical aeration tanks, including a water injection head and a sealing head, and a transparent telescopic sleeve detachably connected between the water injection head and the sealing head for accommodating the aeration pipeline. Fixed structures for fixing the ends of the aeration pipeline are provided on the inner sides of the water injection head and the sealing head. An observation chamber is formed between the inner wall of the transparent telescopic sleeve and the outer wall of the aeration pipeline. A water injection structure for injecting water into the aeration pipeline is provided on the water injection head;
[0007] It also includes a number of plugs that can be threadedly connected to the threaded posts on the aeration pipeline to block the air ports.
[0008] The principle and effect of this basic solution are as follows:
[0009] 1. The aeration pipeline maintenance device for the biochemical aeration tank of the present utility model includes a water injection head and a sealing head, a transparent telescopic sleeve installed between the water injection head and the sealing head. The aeration pipeline to be detected is placed in the transparent telescopic sleeve. The water injection head and the sealing head block the two ports of the aeration pipeline, and the leakage of the aeration pipeline is observed by injecting water into the aeration pipeline.
[0010] 2. Compared with the prior art, the present utility model is provided with a transparent telescopic sleeve, which can accommodate aeration pipelines of different sizes. When the water injection structure injects water into the aeration pipeline sealed in the transparent telescopic sleeve, if the surface of the aeration pipeline is eroded, the injected water will overflow from the aeration pipeline into the transparent telescopic sleeve; if the surface of the aeration pipeline is not eroded and the sealing performance is good, there will be no water overflow in the transparent telescopic sleeve. When the amount of gas leaked through a small gap on the aeration pipeline is small, the existing aeration pipeline maintenance device will generate small and discontinuous bubbles, which are not easy to observe. However, the transparent telescopic sleeve in this biochemical aeration pipeline maintenance device facilitates the inspectors to more intuitively observe the leakage situation of the aeration pipeline to be detected, and solves the problem that in the existing aeration pipeline maintenance device, when the degree of erosion of the surface of the aeration pipeline to be detected is relatively small, during the process of introducing gas into the aeration pipeline to be detected, the amount of gas leaked through the small gap is small, the generated bubbles may be discontinuous and too small in volume, not easy to observe, and the detection of the aeration pipeline will be inaccurate.
[0011] Further, the fixing structure includes pads respectively fixed on the water injection head and the sealing head and used for fixing the ends of the aeration pipeline, and the outer walls of the pads are all attached to the ends of the aeration pipeline. The pads in the water injection head and the sealing head fix and seal the two ports of the aeration pipeline to be detected in the transparent telescopic sleeve, making the detection situation of the aeration pipeline more accurate.
[0012] Further, the shapes of the pads are all cones, and the radii of the pads gradually decrease from the side away from the transparent telescopic sleeve to the inside of the transparent telescopic sleeve. The shape of the pads being cones can seal aeration pipelines of different sizes, increasing the maintenance range of the aeration pipeline maintenance device for the biochemical aeration tank.
[0013] Further, the pads are all made of rubber material. The pads made of rubber material have better sealing performance for the ports of the aeration pipeline, and can more effectively ensure the accuracy of the detection of the aeration pipeline.
[0014] Further, the water injection structure includes a water injection pipe fixed on the water injection head and a through hole penetrating the water injection head and the pad fixed inside. The water injection pipe and the through hole are communicated. The water injection pipe injects water into the aeration pipeline through the through hole to detect the erosion situation of the aeration pipeline, and at the same time does not affect the sealing effect of the pad fixed inside the water injection head on the port of the aeration pipeline.
[0015] Furthermore, a base is provided, the water injection head is fixedly connected to one end of the base, the sealing head can slide on the base, and a limiting structure for positioning the sealing head is provided on the base. The sealing head can slide on the base to seal aeration pipes of different lengths, and the limiting structure on the base limits the sealing head, thereby ensuring the sealing performance of the sealing head to the aeration pipe.
[0016] Furthermore, the base is provided with a through groove, a linear guide rail is provided in the through groove, and the limiting structure is a block that can be clamped between the outer wall of the sealing head and the inner wall of the linear guide rail on the same side.

[0022] The reference numerals in the drawings of the specification include: base 1, sealing head 2, cushion block 3, transparent telescopic sleeve 4, clamping block 5, water injection head 6, and water injection pipe 7.
[0023] A biochemical aeration tank aeration pipeline maintenance device, for example Figure 1 As shown: it includes a water injection head 6 and a sealing head 2, a transparent telescopic sleeve 4 for accommodating an aeration pipe is installed between the water injection head 6 and the sealing head 2, a fixing structure for fixing the end of the aeration pipe is installed on the inner side of the water injection head 6 and the sealing head 2, an observation chamber is formed between the inner wall of the transparent telescopic sleeve 4 and the outer wall of the aeration pipe, and a water injection structure for injecting water into the aeration pipe is installed on the water injection head 6; it also includes a plurality of plugs that can be threadedly connected to the threaded columns on the aeration pipe and seal the air outlet.
[0024] The transparent telescopic sleeve 4 is composed of two integrally formed sleeves and a telescopic sleeve connected between the sleeves. External threads are provided on both sleeves. When the amount of gas leaked from a small gap on the aeration pipe is small, the existing aeration pipe repair device will generate small and discontinuous bubbles, which are not easy to observe. However, the transparent telescopic sleeve 4 in this biochemical aeration tank aeration pipe repair device can not only adapt to aeration pipes of different lengths but also more intuitively observe the leakage condition of the aeration pipe.
[0025] In this embodiment, a base 1 is further provided. The water injection head 6 is fixedly installed at the right end of the base 1. A through groove is provided on the base 1, and a linear guide rail is installed in the through groove. The sealing head 2 is installed on the linear guide rail and can slide on the linear guide rail. Clamping blocks 5 are installed on both sides of the linear guide rail, and the clamping blocks 5 slide on both sides of the linear guide rail. When the sealing head 2 slides on the base 1 and seals the aeration pipe inside the transparent telescopic sleeve 4, the clamping blocks 5 on both sides of the linear guide rail slide to both sides of the sealing head 2 and clamp the sealing head 2, so that the position of the sealing head 2 is fixed and cannot slide on the base 1, ensuring the sealing effect of the sealing head 2 on the aeration pipe.
[0026] The fixing structure includes cushion blocks 3 respectively fixedly installed on the water injection head 6 and the sealing head 2 for fixing the end of the aeration pipe. The outer walls of the cushion blocks 3 are all in contact with the end of the aeration pipe. The shapes of the cushion blocks 3 are all conical, and the radii of the cushion blocks 3 gradually decrease from the side away from the transparent telescopic sleeve towards the inside of the transparent telescopic sleeve 4. Different-sized aeration pipes can be fixed and sealed through the cushion blocks 3, increasing the repair range of the biochemical aeration tank aeration pipe repair device; the cushion blocks 3 are all made of rubber material, and the rubber cushion blocks 3 have better sealing performance for the port of the aeration pipe, which can more effectively ensure the accuracy of the aeration pipe detection; internal threads matching the external threads on the outer walls of the left and right ends of the transparent telescopic sleeve are respectively provided inside the sealing head 2 and the water injection head 6. A water injection structure for injecting water into the aeration pipe is further formed on the water injection head 6. The water injection structure includes a water injection pipe 7 fixedly installed on the right side of the water injection head and a through hole penetrating the water injection head 6 and the cushion block 3 fixedly installed inside. The water injection pipe 7 is communicated with the through hole, and the water injection pipe injects water into the aeration pipe through the through hole to detect the erosion condition of the aeration pipe, and at the same time, it does not affect the sealing effect of the cushion block 3 on the port of the aeration pipe.
[0027] When the utility model is in use, first install the transparent telescopic sleeve 4 and the water injection head 6, block the air port on the aeration pipeline to be detected with a plug, then place the aeration pipeline to be detected into the transparent telescopic sleeve 4, rotatably install the sealing head 2 at the left end of the transparent telescopic sleeve 4, and the cushion blocks 3 in the water injection head 6 and the sealing head 2 fix and seal the two ports of the aeration pipeline to be detected. Inject water into the aeration pipeline to be detected through the water injection pipe at the water injection head 6. If the surface of the aeration pipeline to be detected is eroded, the injected water will overflow from the aeration pipeline into the transparent telescopic pipe and be observed by the tester; if the surface of the aeration pipeline to be detected is not eroded and the sealing performance in the aeration pipeline is good, no water will seep out of the transparent telescopic sleeve 4, then the aeration pipeline does not need to be replaced and can continue to be used.
[0028] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model.
