Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a novel nano aeration tube for sewage treatment. Background Art

[0002] The aeration tube is an oxygen-enhancing device used in sewage treatment. It transports air to the aeration device at the bottom of the pool by blowing air. Its main function is to effectively dissolve oxygen into the water to provide microorganisms for the oxidation and decomposition of organic matter.

[0003] Usually, the aeration equipment commonly used in sewage treatment plants include rotary mixing aerators, tubular aerators and diamond aeration plates. The aeration efficiency of rotary mixing aerators and tubular aeration plates is relatively low, so the diamond aeration plate has a larger effective area and its pore size is smaller and more uniform, making the bubbles it produces denser and more applicable. However, when the diamond aeration plate is in use, it is very easy for the lubricating oil and gas carried by the Roots blower or the rotary blower wind chamber to accumulate inside, causing the air outlet pores to be blocked.

[0004] In order to reduce the blockage of pores, an aeration pipe is disclosed in the patent document with application number 202121494797.7, in which a cleaning mechanism is installed inside the aeration pipe to clean the inside of the aeration pipe body. However, in this technical scheme, the aeration pipe is usually small in size, and the cost of installing a cleaning mechanism inside the aeration pipe is high. In addition, when the diamond aeration disc is in use, since the pores of the diamond aeration disc are more uniform and dense, the lubricating oil and gas can easily cause blockage to the pores on the diamond aeration disc, affecting the use effect of the diamond aeration disc. Utility Model Content

[0005] The technical problem solved by the utility model is to solve the problem in the prior art that lubricating oil gas easily enters into the pores of the diamond aeration plate to cause pore blockage, thereby affecting the normal use of the diamond aeration plate.

[0007] A further technical improvement of the utility model is that the purification connection assembly comprises a mounting base plate, a mesh plate is arranged inside the mounting base plate, and a filter sponge for purifying oil and gas in the air is arranged on the mesh plate.

[0009] A further technical improvement of the utility model is that the output device comprises a first-layer output connecting tube for threaded connection with the side threaded hole, and a first-layer output disk is arranged at the output end of the first-layer output connecting tube.

[0010] The further technical improvement of the utility model is that the first layer output disk comprises an aeration output body, and a plurality of groups of micro-air filters are evenly arranged on the aeration output body.

[0011] A further technical improvement of the utility model is that the arrangement density of the micropores is 1000-1800 per meter.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] See also Figure 1-4 As shown, a new type of nano aeration tube for sewage treatment includes a connecting air pipe 1 for connecting to an air intake device, wherein the connecting air pipe 1 is a horizontal pipe, and a plurality of branch air pipes 2 are evenly installed on the connecting air pipe 1, and the branch air pipes 2 are used to receive air from the connecting air pipe 1, and at the same time, a plurality of outlet pipe components 3 for allowing air to enter sewage are evenly arranged on each branch air pipe 2.

[0024] When in use, firstly, the connecting air pipe 1, the branch air pipe 2 and the outlet pipe assembly 3 are arranged at the bottom of the sewage reaction tank, and the air is allowed to enter by using the air intake device. For example, in the present application, a Roots blower or a rotary blower is used to allow air to enter the inside of the connecting air pipe 1. Since the size of the connecting air pipe 1 is larger than that of the branch air pipe 2, filter cotton for preliminary filtering of oil and gas is installed inside the connecting air pipe 1 to preliminarily purify the air to reduce the amount of oil and gas entering the position of the outlet pipe assembly 3. Subsequently, the air is diverted through the branch air pipe 2 to transport the air to the inside of each branch air pipe 2. Finally, the gas escapes into the sewage through the outlet pipe assembly 3 to provide oxygen in the sewage.

[0025] The outlet pipe assembly 3 includes an output air pipe 33, wherein the output air pipe 33 is fixedly mounted on the branch air pipe 2, and a purification connection assembly 36 is detachably mounted on the output air pipe 33, wherein a plurality of groups of first-layer output connection pipes 31 are threadedly mounted on the purification connection assembly 36, and a first-layer output disk 32 is arranged at the output end of the first-layer output connection pipe 31. When in use, when the gas in the branch air pipe 2 enters the output air pipe 33, the output air pipe 33 purifies the gas again through the purification connection assembly 36, purifies the residual oil and gas in the air, and discharges the purified air through the first-layer output connection pipe 31 to the first-layer output disk 32 for output. In this process, by providing a plurality of first-layer output disks 32, a plurality of nozzles can be provided on each outlet pipe assembly 3, thereby obtaining relatively dense bubbles, and expanding the coverage of the bubbles to ensure sufficient oxygen inside the sewage treatment tank.

[0026] As a further embodiment of the present application, a bottom air pipe is fixed on the side of the purification connection assembly 36 away from the output air pipe 33, and the bottom air pipe is connected to a plurality of groups of second-layer output connecting pipes 34, wherein the output end of the second-layer output connecting pipe 34 is provided with a second-layer output disk 35 for realizing gas discharge. In the present application, the first-layer output disk 32 and the second-layer output disk 35 have the same structure, but the length of the first-layer output connecting pipe 31 is smaller than the length of the second-layer output connecting pipe 34, thereby further expanding the coverage range of the bubbles and ensuring sufficient oxygen in the sewage treatment tank.

[0027] Taking the first layer output disc 32 as an example, the first layer output disc 32 in the present application includes an aeration output body 322, and a plurality of micropores 321 for achieving gas outflow are evenly arranged on the aeration output body 322. The arrangement density of the micropores 321 is 1000-1800 per meter.

[0028] The aeration system is easy to install and disassemble, easy to maintain, and convenient for cleaning and regeneration of the fiber aeration tube. In addition, the micropores 321 in the present application are arranged at a high density, which can achieve denser bubbles during aeration. The bubble diameter is 0.5-2mm, with less resistance and better resistance to blockage.

[0029] In the present application, the purification connection assembly 36 includes a mounting substrate 361, and side threaded holes 362 for threaded connection with the first layer output connection pipe 31 are evenly opened on the side of the mounting substrate 361. The mounting substrate 361 is a hollow structure, and a filter cavity 366 for air filtration is arranged in the middle. A threaded mounting plate 365 is threadedly installed above the mounting substrate 361, and a top threaded hole 364 for threaded connection with the output air pipe 33 is opened on the threaded mounting plate 365. A bottom hole for threaded connection with the bottom air pipe is opened at the bottom of the mounting substrate 361. A mesh plate 367 is fixedly installed inside the filter cavity 366, and a filter sponge 363 is attached to one side of the mesh plate 367 close to the threaded mounting plate 365. When in use, First, attach the filter sponge 363 to the mesh plate 367, then fix the threaded mounting plate 365 on the mounting base plate 361, connect the mounting base plate 361 to the output air pipe 33 through the top threaded hole 364, then thread the first-layer output connecting pipe 31 on the side threaded hole 362 to install the first-layer output connecting pipe 31. When the gas enters through the output air pipe 33, the residual oil and gas are purified by the filter sponge 363. After purification, the air passes through the mesh plate 367 and enters the first-layer output connecting pipe 31, and enters the second-layer output connecting pipe 34 through the bottom hole. The first-layer output disk 32 and the second-layer output disk 35 are used to allow air to enter the sewage treatment pool to supplement oxygen in the sewage pool.

[0030] When the utility model is used, the connecting air pipe 1, the branch air pipe 2 and the outlet pipe assembly 3 are first arranged at the bottom of the sewage reaction tank, and the air is introduced by the air intake device. For example, in the present application, a Roots blower or a rotary blower is adopted to allow the air to enter the inside of the connecting air pipe 1. Since the size of the connecting air pipe 1 is larger than that of the branch air pipe 2, a filter cotton for preliminary filtering of oil and gas is installed inside the connecting air pipe 1 to perform preliminary purification of the air, so as to reduce the amount of oil and gas entering the position of the outlet pipe assembly 3. Subsequently, the air is diverted through the branch air pipe 2 to transport the air to the inside of each branch air pipe 2, and finally, the gas is released into the sewage through the outlet pipe assembly 3 to provide oxygen in the sewage.

[0031] When the outlet pipe assembly 3 is in use, the filter sponge 363 is first attached to the mesh plate 367, and then the threaded mounting plate 365 on the mounting base plate 361 is fixed, and the mounting base plate 361 is connected to the output air pipe 33 through the top threaded hole 364, and then the first layer output connecting pipe 31 is threadedly mounted on the side threaded hole 362 to achieve the installation of the first layer output connecting pipe 31. When the gas enters through the output air pipe 33, the residual oil and gas are purified by the filter sponge 363, and after purification, the air passes through the mesh plate 367 to enter the first layer output connecting pipe 31, and enters the second layer output connecting pipe 34 through the bottom hole, and the first layer output disk 32 and the second layer output disk 35 are used to realize the entry of air into the sewage treatment pool to supplement oxygen in the sewage pool.
