Description

TECHNICAL FIELD

[0001] The utility model belongs to the water area aeration technical field, more particularly to an aeration device. BACKGROUND

[0002] The aeration device plays a crucial role in sewage treatment and environmental engineering, improving water treatment efficiency and environmental quality through oxygen supply, stirring, pollutant removal, and water quality improvement.

[0003] The aeration device in the related art adopts the following two ways:

[0004] First, the bottom structure of the aeration device usually adopts an internal thread tee, the two sides of the internal thread tee are connected to the tubular microporous aerator by double external thread joints, and the bottom of the internal thread tee is generally suspended in the pool without fixation. Since there is no fulcrum at the bottom, the vibration force generated during the aeration process can only act on the connection between the tubular microporous aerator and the aeration standpipe, and the connection thread is prone to loosening or falling off after long-term use, thereby affecting the service life of the aeration pipe and the aeration effect.

[0005] Second, a nut is welded on one side of the internal thread tee of the aeration device, and the aeration standpipe is in rigid contact with the pool bottom by adjusting the bolt. When replacing the tubular microporous aerator, production needs to be stopped, and after cleaning the pool, manual replacement of the tubular microporous aerator is required, which cannot meet the demand for replacing the tubular microporous aerator during continuous production in the later period.

[0006] Therefore, how to connect the tubular microporous aerator with the pool bottom without affecting the online replacement of the aeration device to reduce the probability of falling off of the tubular microporous aerator is a technical problem to be solved at present.

DETAILED DESCRIPTION

[0058] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0059] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components can be exaggerated or reduced.

[0060] Some embodiments of the present application will be described in detail below in conjunction with the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0061] Please refer to Figure 1 At least one embodiment provides an aeration device, comprising the following structures.

[0062] Intake main pipe 100, which is used for conveying the gas sucked by the remote blower.

[0063] N sub-aeration assemblies 200, which are communicated with the intake main pipe 100 through corresponding aeration valves 300, wherein N≥1. The positions of the N sub-aeration assemblies 200 are set according to the aeration demand.

[0064] It should be noted that the size of the aeration amount is adjusted by adjusting the opening degree of the aeration valve 300.

[0065] Please refer to Figure 1 and Figure 2The structure of the sub-aeration assembly 200 is described below, which comprises a vertical pipe 210, a tubular micro-porous aerator 220, a connecting piece 230 and an elastic abutting piece 240. The tubular micro-porous aerator 220 is two in number and is arranged on both sides of the connecting piece 230.

[0066] The connecting piece 230 is arranged at the lower end of the vertical pipe 210 and communicates with the vertical pipe 210. The connecting piece 230 is used to connect various devices of the sub-aeration assembly 200, and at the same time, the gas is delivered from the vertical pipe 210 to the tubular micro-porous aerator 220.

[0067] The tubular micro-porous aerator 220 is arranged approximately horizontally and communicates with the connecting piece 230. The tubular micro-porous aerator 220 is used to aerate the liquid in the pool. Wherein, approximately horizontally arranged means that there is an error of 0-5° with the absolute horizontal state.

[0068] The bottom of the connecting piece 230 is abutted with the pool bottom 400 of the area to be aerated by the elastic abutting piece 240.

[0069] The elastic abutting mode makes the overall structure of the sub-aeration assembly 200 elastically abut with the pool bottom 400, thereby absorbing the vibration of the pipeline when the aeration valve 300 is opened and closed, thereby reducing the probability of falling of the tubular micro-porous aerator 220.

[0070] When the tubular micro-porous aerator 220 needs to be replaced, only the corresponding aeration valve 300 needs to be closed, the sub-aeration assembly 200 is lifted out of the water surface after being disassembled, and the online replacement is completed. In the case where the pool cannot be cleaned, the self-fixing of the sub-aeration assembly 200 can be completed without entering the pool.

[0071] At the same time, the elastic abutting connection mode has higher adaptability to the pool bottom 400 with poor flatness, and meets the fixing requirements of the aeration device.

[0072] Please refer to Figure 2 and Figure 3 The elastic abutting piece 240 comprises a sleeve 241, an abutting nail 242 and a reset spring 243.

After the needle tip of the abutting nail passes through the expansion hole 2411, it extends out of the sleeve 241, and the needle head of the abutting nail remains in the sleeve 241.

[0074] The reset spring 243 is arranged in the sleeve 241 and abuts against the head of the abutting nail 242. During installation or replacement, the head of the abutting nail presses the reset spring 243, so as to adjust the height of the sub-aeration assembly 200, so that the sub-aeration assembly 200 can abut against the pool bottom 400. Meanwhile, when the aeration valve 300 is opened or closed, the gas can cause the pipeline to vibrate, and at this time, the reset spring 243 can absorb the vibration, so as to reduce the looseness of the threaded connection of the tubular micro-porous aerator 220, thereby reducing the probability of falling of the tubular micro-porous aerator 220.

[0075] Please refer to Figure 4 In some embodiments, the elastic abutting member 240 comprises a connecting block 244 and a telescopic spring 245, one end of the telescopic spring 245 is arranged on the bottom surface of the connecting member 230 through the connecting block 244. The telescopic spring 245 directly abuts against the pool bottom 400, and during installation or replacement, the telescopic spring 245 is pressed, so as to adjust the height of the sub-aeration assembly 200, so that the sub-aeration assembly 200 can abut against the pool bottom 400. Meanwhile, when the aeration valve 300 is opened or closed, the gas can cause the pipeline to vibrate, and at this time, the telescopic spring 245 can absorb the vibration, so as to reduce the looseness of the threaded connection of the tubular micro-porous aerator 220, thereby reducing the probability of falling of the tubular micro-porous aerator 220.

[0076] Please continue to refer to Figure 2 and Figure 3 The connecting member 230 comprises an inner-thread four-way pipe 231, a single outer-thread joint 232, a double-end outer-thread plug 233 and two double outer-thread joints 234. The single outer-thread joint 232, the double-end outer-thread plug 233 and the two double outer-thread joints 234 are threadedly connected with the inner-thread four-way pipe 231, so that the device can be easily replaced, and meanwhile, the airtightness of the connection is ensured.

[0077] The vertical pipe 210 is threadedly connected with the threaded opening at the top of the inner-thread four-way pipe 231 through the single outer-thread joint 232.

[0078] The tubular micro-porous aerator 220 is threadedly connected with the threaded opening of the side wall of the inner-thread four-way pipe 231 through the double outer-thread joint 234.

[0079] The elastic abutting member 240 is threadedly connected with the threaded opening at the bottom of the inner-thread four-way pipe 231 through the double-end outer-thread plug 233.

[0080] Please continue to refer to Figure 1 In order to facilitate the disassembly of the sub-aeration assembly 200, in the preferred embodiments, the first connecting flange 310 and the second connecting flange 320 are arranged between the aeration valve 300 and the vertical pipe 210. The sub-aeration assembly 200 and the aeration valve 300 are fixed by using the detachable connecting mode, so that the sub-aeration assembly 200 can be easily replaced and maintained later.

[0081] The first connecting flange 310 is arranged at the end of the pipeline of the air outlet of the aeration valve 300. The first connecting flange 310 is integrally formed with the pipeline of the air outlet of the aeration valve 300.

[0082] The second connecting flange 320 is arranged at the top of the riser 210. The second connecting flange 320 is integrally formed with the riser 210.

[0083] The first connecting flange 310 and the second connecting flange 320 are fixed by bolts 340. The fixing mode of the bolts 340 can facilitate disassembly and improve disassembly efficiency.

[0084] Meanwhile, in order to ensure the airtightness of the connection between the first connecting flange 310 and the second connecting flange 320, a rubber pad 330 is arranged between the first connecting flange 310 and the second connecting flange 320. The connection between the first connecting flange 310 and the second connecting flange 320 is sealed by the rubber pad 330, which reduces gas leakage and improves aeration effect.

[0085] Please refer to Figure 1 At least one embodiment also provides an aeration device comprising the following structure.

[0086] An air inlet main pipe 100 for conveying the gas sucked by the remote blower.

[0087] N sub-aeration assemblies 200, which are in communication with the air inlet main pipe 100 through corresponding aeration valves 300, wherein N≥1; the bottom of each sub-aeration assembly 200 is elastically connected to the pool bottom 400 of the area to be aerated. The overall structure of the sub-aeration assembly 200 is elastically supported by the pool bottom 400, so as to absorb the vibration of the pipeline when the aeration valve 300 is opened and closed, and reduce the loosening of the components in the sub-aeration assembly 200 due to vibration.

[0088] Meanwhile, when the sub-aeration assembly 200 needs to be repaired and replaced, only the corresponding aeration valve 300 needs to be closed, and the sub-aeration assembly 200 is lifted out of the water surface after being disassembled, so as to complete online replacement. The self-fixing of the sub-aeration assembly 200 can be completed without entering the pool.

[0089] Meanwhile, the elastic supporting connection mode can also have high adaptability to the pool bottom 400 with poor flatness, and meet the fixing requirements of the aeration device.

[0090] Please continue to refer to Figure 1 and Figure 4The sub-aeration assembly 200 further comprises an elastic abutting member 240; the sub-aeration assembly 200 is elastically connected with the pool bottom 400 of the area to be aerated through the elastic abutting member 240.

[0091] Please refer to Figure 1 In some embodiments, the elastic abutting member 240 comprises a sleeve 241, an abutting needle 242, and a reset spring 243.

[0092] The bottom surface of the sleeve 241 is provided with an elastic hole 2411 for the needle tip of the abutting needle 242 to pass through. After the needle tip of the abutting needle passes through the elastic hole 2411, it extends out of the sleeve 241, and the needle head of the abutting needle remains in the sleeve 241.

[0093] The reset spring 243 is arranged in the sleeve 241 and abuts against the needle head of the abutting needle 242.

[0094] During installation or replacement, the needle head of the abutting needle is pressed against the reset spring 243, so as to adjust the height of the sub-aeration assembly 200, so that it can abut against the pool bottom 400. Meanwhile, when the aeration valve 300 is opened and closed, the gas will cause the pipeline to vibrate, at which time the reset spring 243 absorbs the vibration, thereby reducing the loosening of the threaded connection of the tubular microporous aerator 220, and reducing the probability of falling of the tubular microporous aerator 220.

[0095] Please refer to Figure 4 In some embodiments, the elastic abutting member 240 comprises a connecting block 244 and an elastic spring 245; one end of the elastic spring 245 is connected with the sub-aeration assembly 200 through the connecting block 244.

[0096] The elastic spring 245 is directly used for abutting against the pool bottom 400. During installation or replacement, the elastic spring 245 is pressed, so as to adjust the height of the sub-aeration assembly 200, so that it can abut against the pool bottom 400. Meanwhile, when the aeration valve 300 is opened and closed, the gas will cause the pipeline to vibrate, at which time the elastic spring 245 absorbs the vibration, thereby reducing the loosening of the threaded connection of the tubular microporous aerator 220, and reducing the probability of falling of the tubular microporous aerator 220.
