Description

Technical Field

[0001] The invention relates to the technical field of water treatment engineering, and in particular to a method for accurately positioning an aeration pipe device and replacing the aeration pipe. Background Art

[0002] In environmental water treatment, an aeration hose is often used in the biochemical pool. The main purpose of aeration is to fill the sewage with air to provide the necessary oxygen for aerobic microorganisms. These microorganisms can more effectively decompose organic pollutants in sewage under aerobic conditions, converting them into carbon dioxide, water and new cell substances. Aeration also helps to mix sewage, ensure that organic matter, nutrients and microorganisms in sewage are evenly distributed, and improve treatment efficiency. At the same time, good mixing can prevent sludge from settling at the bottom of the pool, keep the activated sludge in a suspended state, and facilitate full contact between microorganisms and pollutants. The oxygen provided by aeration supports the metabolic activities of aerobic microorganisms and accelerates the nitrification process of ammonia nitrogen in sewage (that is, the process of oxidizing ammonia to nitrite and nitrate), which is an important step in removing nitrogen from sewage; the aeration hose is used to provide oxygen to aerobic microorganisms in the biochemical pool. These microorganisms can more effectively decompose organic matter in sewage under aerobic conditions, thereby enabling sewage to meet discharge standards.

[0003] In order to ensure that the aeration hose can work normally, it is necessary to replace the aeration hose regularly. Since the aeration hose is usually in the sewage at the bottom of the aeration tank, replacing the aeration hose requires stopping production and cleaning the tank, which wastes a lot of manpower, material resources and time and has high costs. Therefore, there is an urgent need for a method for accurately positioning the aeration tube device and replacing the aeration tube, so that the aeration tube can be replaced without stopping production and cleaning the tank.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-Figure 2The present invention provides an aeration pipe device for accurately positioning, including a fixing frame 31 fixedly connected to the bottom of a biochemical pool 5, a plurality of aeration hoses 3 are slidably connected to the fixing frame 31, one end of the aeration hose 3 is connected to a main air pipe 1 through a branch air pipe 2, the branch air pipe 2 is detachably connected to the main air pipe 1, a positioning component for guiding the branch air pipe 2 is arranged on the side of the branch air pipe 2 facing the inner wall of the biochemical pool 5, and a limiting component for guiding the aeration hose 3 is arranged on the end of the aeration hose 3 away from the branch air 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 effectively move vertically along the front pool wall 26 of the biochemical pool 5, and at the same time guides the aeration hose 3 through the limiting component, so that the replaced aeration hose 3 can be effectively located at a specified position in the fixing frame 31; the present invention can replace the aeration hose 3 with precise positioning without stopping the biochemical pool 5 for pool cleaning.

[0030] Further optimized solution, the positioning assembly includes a connecting piece 21 fixedly connected to the gas distribution pipe 2, a plurality of through holes are opened on the connecting piece 21, a steel wire 22 is slidably connected in the through hole, a channel steel 25 is arranged on the steel wire 22, the channel steel is fixedly connected to the bottom of the biochemical pool 5, and both ends of the steel wire 22 are installed on the top surface of the front pool wall 26 of the biochemical pool 5 by bolts. The connecting piece 21 moves along the steel wire 22, so that the gas distribution pipe 2 can move up and down along the steel wire 22 on the front pool wall 26 of the biochemical pool 5.

[0031] In a further optimized solution, the steel wire rope 22 sequentially passes through a through hole on the connecting piece 21, the channel steel 25 and another through hole on the connecting piece 21. Both ends of the steel wire rope 22 can be installed on the top surface of the front pool wall 26 of the biochemical pool 5 by bolts.

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

[0033] The latch 23 and the positioning hole of the locator 24 adopt a matching connection method, that is, when the latch 23 adopts a cylinder, the positioning hole of the locator 24 adopts a cylinder matched with the cylinder, so that the cylinder can be effectively inserted into the cylinder; when the latch 23 adopts a polygonal column, the positioning hole of the locator 24 adopts a cylinder matched with the polygonal column, so that the polygonal column can be effectively inserted into the positioning hole of the locator 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 configured to be pointed. By configuring the end of the pin 23 facing the locator 24 to be pointed, the pin 23 can be effectively inserted into the positioning hole of the locator 24.

[0035] The limiting assembly 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 releasing the tail rope 4, the aeration hose 3 can move along a specified path in the fixing frame 31, and the fixing frame 31 can accurately position the aeration hose 3.

[0036] In a further optimized solution, the positioning hook 44 is fixedly connected to the top surface of the rear pool wall 41 of the biochemical pool 5. By installing the positioning hook 44 on the top surface of the rear pool wall 41 of the biochemical pool 5, it is convenient for operators to take and place the tail rope 4.

[0037] In a further optimized solution, the tail rope 4 is slidably connected to the limit steel pipe 43 near the aeration hose 3, and the limit steel pipe 43 is fixedly connected to the bottom of the biochemical pool 5 through a steel frame. When the aeration hose 3 is replaced, the aeration hose 3 is tightly abutted against the limit steel pipe 43.

[0038] The tail rope 4 is guided by the limiting steel pipe 43 to prevent the aeration hose 3 from tilting, so that the tail rope 4 can effectively drive the aeration hose 3 to move in the fixing frame 31.

[0039] A positioning ring 42 is fixedly connected to one side of the limiting steel pipe 43 facing the inner wall rear pool wall 41 of the biochemical pool 5. The positioning ring 42 is used to limit and guide the tail rope 4 so that the tail rope 4 will not shake.

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

[0041] A method for replacing an aeration tube comprises the following steps:

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

[0043] S2. Separate the air distribution pipe 2 from the main air pipe 1 by releasing the limit assembly, pull the air distribution pipe 2 upward, and pull the aeration hose 3 out of the fixing frame 31; that is, when the air distribution pipe 2 is separated from the main air pipe 1, remove the tail rope 4 from the positioning hook 44 at the same time, the length of the connecting tail rope 4 is 2-3 times the length of the aeration hose 3, pull the air distribution pipe 2 upward to pull up the aeration hose 3; at this time, the remaining amount of the tail rope 4 is still outside the biochemical pool 5, so it is convenient 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 a new aeration hose 3 on the air distribution pipe 2 and the tail rope 4; the aeration hose 3 and the tail rope 4 can be connected by tying a knot, tying, etc.

[0045] S4. After the replacement of the aeration hose 3 is completed, the air distribution pipe 2 is accurately reset through the positioning component, and the aeration hose 3 is accurately reset to the original position of the fixing frame 31 through the limiting component; that is, by retracting the tail rope 4, the tail rope 4 moves along the guidance of 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 the aeration hose 3 can be accurately positioned at the original position on the fixing frame 31.

[0046] When the replaced aeration hose 3 is being reset, the aeration hose 3 drives the air distribution pipe 2 to move, and 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 locator 24, the air distribution pipe 2 can be positioned; at this time, the tail rope 4 can accurately return to the original position, so that the tail rope 4 can accurately position the aeration hose 3.

[0047] S5. After the air distribution pipe 2 and the aeration hose 3 are reset, the limit assembly is locked. That is, after the aeration hose 3 is accurately positioned at the original position on the fixing frame 31, the tightened tail rope 4 is installed on the positioning hook 44 to complete the replacement of the aeration hose 3.

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

[0049] The present invention is easy to operate and can effectively and accurately position the aeration hose 3 online without stopping the production and cleaning the biochemical pool.
