Description

Technical Field

[0001] This invention relates to the field of water treatment engineering technology, and in particular to a device for precisely locating aeration pipes and a method for replacing aeration pipes. Background Technology

[0002] In environmental water treatment, aeration hoses are frequently used in biological treatment tanks. The main purpose of aeration is to introduce air into the wastewater, providing the necessary oxygen for aerobic microorganisms. Under aerobic conditions, these microorganisms can more effectively decompose organic pollutants in the wastewater, converting them into carbon dioxide, water, and new cellular material. Aeration also helps mix the wastewater, ensuring a uniform distribution of organic matter, nutrients, and microorganisms, thus improving treatment efficiency. Simultaneously, good mixing prevents sludge from settling at the bottom of the tank, keeping activated sludge in suspension, which facilitates full contact between microorganisms and pollutants. The oxygen provided by aeration supports the metabolic activities of aerobic microorganisms, accelerating the nitrification process of ammonia nitrogen in the wastewater (the oxidation of ammonia to nitrite and nitrate), a crucial step in nitrogen removal. The aeration hoses provide oxygen to the aerobic microorganisms in the biological treatment tank, enabling them to more effectively decompose organic matter in the wastewater, thus ensuring that the wastewater meets discharge standards.

[0003] In order for the aeration hose to work properly, it needs to be replaced regularly. Since the aeration hose is usually located in the sewage at the bottom of the aeration tank, replacing the aeration hose requires shutting down the tank for cleaning, which wastes a lot of manpower, resources and time, resulting in high costs. Therefore, there is an urgent need for a method to accurately locate the aeration hose device and replace the aeration hose, so that the aeration hose can be replaced without shutting down the tank for cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide a method for accurately locating an aeration pipe device and replacing the aeration pipe, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following solution: a device for precisely positioning aeration pipes, comprising a fixed frame fixedly connected to the bottom of a biological treatment tank, a plurality of aeration hoses slidably connected to the fixed frame, one end of each aeration hose being connected to a main air pipe via a distribution pipe, the distribution pipe being detachably connected to the main air pipe, a positioning component for guiding the distribution pipe being provided on the side of the distribution pipe facing the inner wall of the biological treatment tank, and a limiting component for guiding the aeration hose being provided on the end of the aeration hose away from the distribution pipe.

[0006] Preferably, the positioning component includes a connecting piece fixedly connected to the gas distribution pipe, the connecting piece having a plurality of through holes, a steel wire rope slidably connected in the through holes, a channel steel being provided on the steel wire rope, the channel steel being fixedly connected to the bottom of the biochemical tank, and the two ends of the steel wire rope being bolted to the top surface of the front wall of the biochemical tank.

[0007] Preferably, the wire rope passes sequentially through one through hole on the connecting piece, the channel steel, and another through hole on the connecting piece.

[0008] Preferably, a pin is fixedly connected to the end of the air distribution pipe near the aeration hose, and the pin is detachably connected to the positioning hole of a positioner, the positioner being fixedly connected to the channel steel.

[0010] Preferably, the positioning hook is fixedly connected to the top surface of the rear wall of the biochemical tank.

[0011] Preferably, the portion of the tail rope near the aeration hose is slidably connected to a limiting steel pipe, and the limiting steel pipe is fixedly connected to the bottom of the biological tank via a steel frame.

[0012] Preferably, a positioning ring is fixedly connected to one side of the rear wall of the biochemical tank, facing the inner wall of the limiting steel pipe.

[0013] Preferably, the tail rope passes through the positioning ring located at the lower part of the limiting steel pipe.

[0014] A method for replacing an aeration pipe includes the following steps:

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-2The present invention provides a device for precisely positioning aeration pipes, including a fixed frame 31 fixedly connected to the bottom of a biological tank 5, a plurality of aeration hoses 3 slidably connected on the fixed frame 31, one end of the aeration hose 3 being connected to a main air pipe 1 through a distribution pipe 2, the distribution pipe 2 being detachably connected to the main air pipe 1, a positioning component for guiding the distribution pipe 2 being provided on the side of the distribution pipe 2 facing the inner wall of the biological tank 5, and a limiting component for guiding the aeration hose 3 being provided on the end of the aeration hose 3 away from the distribution pipe 2.

[0029] When replacing the aeration hose 3, the present invention guides the air distribution pipe 2 through the positioning component, so that the air distribution pipe 2 can move vertically along the front wall 26 of the biological treatment tank 5. At the same time, the limiting component guides the aeration hose 3, so that the replaced aeration hose 3 can be effectively positioned in the designated position within the fixing frame 31. The present invention can perform precise positioning of the aeration hose 3 for replacement without stopping the production and cleaning of the biological treatment tank 5.

[0030] A further optimized design includes a positioning component comprising a connecting piece 21 fixedly connected to the gas distribution pipe 2. The connecting piece 21 has several through holes, within which a steel wire rope 22 is slidably connected. A channel steel 25 is mounted on the steel wire rope 22, and the channel steel is fixedly connected to the bottom of the biological treatment tank 5. Both ends of the steel wire rope 22 are bolted to the top surface of the front wall 26 of the biological treatment tank 5. By moving the connecting piece 21 along the steel wire rope 22, the gas distribution pipe 2 can move up and down along the steel wire rope 22 on the front wall 26 of the biological treatment tank 5.

[0031] In a further optimized design, the steel wire rope 22 passes sequentially through one through hole in the connecting piece 21, the channel steel 25, and another through hole in the connecting piece 21. This allows both ends of the steel wire rope 22 to be bolted to the top surface of the front wall 26 of the biological treatment tank 5.

[0032] In a further optimized design, a pin 23 is fixedly connected to the end of the air distribution pipe 2 near the aeration hose 3. The pin 23 is detachably connected to the positioning hole of the positioner 24, and the positioner 24 is fixedly connected to the channel steel 25. By inserting the pin 23 into the positioning hole of the positioner 24, the air distribution pipe 2 can be effectively prevented from shaking in the biological tank 5, so that the aeration hose 3 can be stably placed in the fixing frame 31.

[0033] The positioning holes of the pin 23 and the positioner 24 are connected in a matching manner. That is, when the pin 23 is a cylinder, the positioning hole of the positioner 24 is a cylinder that is compatible with the cylinder, so that the cylinder can be effectively inserted into the cylinder; when the pin 23 is a polygonal cylinder, the positioning hole of the positioner 24 is a cylinder that is compatible with the polygonal cylinder, so that the polygonal cylinder can be effectively inserted into the positioning hole of the positioner 24.

[0034] In order to enable the pin 23 to be effectively inserted into the positioning hole of the locator 24, the end of the pin 23 facing the locator 24 is set into a pointed shape. By setting the end of the pin 23 facing the locator 24 into a pointed shape, the pin 23 can be effectively inserted into the positioning hole of the locator 24.

[0035] The limiting component includes a tail rope 4, one end of which is detachably connected to the aeration hose 3, and the other end of which is detachably connected to a positioning hook 44. By retracting or extending the tail rope 4, the aeration hose 3 can move along a designated path within the fixing frame 31, and the fixing frame 31 can precisely position the aeration hose 3.

[0036] The design was further optimized by fixing the positioning hook 44 to the top surface of the rear wall 41 of the biological treatment tank 5. By installing the positioning hook 44 on the top surface of the rear wall 41 of the biological treatment tank 5, it is easier for operators to retrieve and place the tail rope 4.

[0037] In a further optimized design, the portion of the tail rope 4 near the aeration hose 3 is slidably connected to a limiting steel pipe 43, which is then fixedly connected to the bottom of the biological treatment tank 5 via a steel frame. After the aeration hose 3 is replaced, it will be tightly abutted against the limiting steel pipe 43.

[0038] The tail rope 4 is guided by the limiting steel pipe 43 to prevent the aeration hose 3 from tilting upwards. This allows the tail rope 4 to effectively move the aeration hose 3 within the fixing frame 31.

[0039] A positioning ring 42 is fixedly connected to the side of the rear wall 41 of the biological tank 5, which faces the inner wall of the limiting steel pipe 43. The positioning ring 42 limits and guides the tail rope 4, preventing it from swaying.

[0040] In a further optimized design, the tail rope 4 passes through the positioning ring 42 and is wound around the lower part of the limiting steel pipe 43. By placing the tail rope 4 below the limiting steel pipe 43 and allowing it to move through the limiting steel pipe 43, when the tail rope 4 drives the aeration hose 3 to move along the fixed frame 31, and the end of the aeration hose 3 abuts against the gap between the limiting steel pipe 43 and the fixed frame 31, the aeration hose 3 can be accurately positioned within the fixed frame 31.

[0041] A method for replacing an aeration pipe includes the following steps:

[0042] S1. Remove the air distribution pipe 2 from the main air pipe 1; that is, first close the valve on the air distribution pipe 2 that needs to be removed. At this time, the air distribution pipe 2 is not connected to the main air pipe 1, while the other air distribution pipes 2 are connected to the main air pipe 1, so that aeration can continue.

[0043] S2. By releasing the limiting component, separate the air distribution pipe 2 from the main air pipe 1, pull the air distribution pipe 2 upward, and pull the aeration hose 3 out from the fixing frame 31; that is, when the air distribution pipe 2 is separated from the main air pipe 1, at the same time remove the tail rope 4 from the positioning hook 44. The length of the tail rope 4 is 2-3 times the length of the aeration hose 3. Pull the air distribution pipe 2 upward to pull the aeration hose 3 up; at this time, the remaining length of the tail rope 4 is still outside the biological tank 5, which makes it easy to pull the replaced aeration hose 3 back to the fixing frame 31 through the tail rope 4.

[0044] S3. Replace the aeration hose 3; remove the aeration hose 3 from the air distribution pipe 2 and the tail rope 4, and then install the new aeration hose 3 onto the air distribution pipe 2 and the tail rope 4; the connection between the aeration hose 3 and the tail rope 4 can be made by knotting, binding, etc.

[0045] S4. After replacing the aeration hose 3, accurately reset the air distribution pipe 2 using the positioning component, and precisely reset the aeration hose 3 to the original position of the fixing frame 31 using the limiting component; that is, by retracting the tail rope 4, the tail rope 4 moves along the positioning ring 42 and the limiting steel pipe 43, so that the tail rope 4 can effectively drive the aeration hose 3 to move along the original installation position, and accurately position the aeration hose 3 at the original position on the fixing frame 31.

[0046] When the new aeration hose 3 is being reset, the aeration hose 3 moves the air distribution pipe 2. The air distribution pipe 2 descends under the limit of the connecting piece 21 and the wire rope 22. When the pin 23 is inserted into the positioner 24, the air distribution pipe 2 can be positioned. At this time, the tail rope 4 can accurately return to its original position, so that the tail rope 4 can accurately position the aeration hose 3.

[0047] S5. After the air distribution pipe 2 and aeration hose 3 are reset, the limiting component is locked. That is, after the aeration hose 3 is precisely positioned in its original position on the fixing frame 31, the taut tail rope 4 is installed onto the positioning hook 44 to complete the replacement of the aeration hose 3.

[0048] Repeat the above process to replace the next aeration hose 3.

[0049] This invention is simple to operate and can effectively and precisely replace the aeration hose 3 online without stopping the production and cleaning of the biological treatment tank.
