Description

Technical Field

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

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, and catering. Aerators are essential equipment for aeration and oxygenation of water supply and drainage. They are more commonly used in sewage treatment operations. According to the method of use, they can be divided into surface aerators and underwater aerators. Among them, underwater aerators mainly include microporous aerators and jet aerators. Among them, the microporous aerator has a small aeration bubble diameter, a small gas-liquid interface diameter, a large gas-liquid interface area, uniform bubble diffusion, and is not prone to pore blockage and has strong corrosion resistance.

[0003] Although the existing aerators are not prone to micropore blockage due to their micropore design, dirt is easily accumulated on the surface of the aerator due to the long-term placement of the aerator at the bottom of sewage, thereby covering the membrane on the surface and blocking the aeration micropores. At this time, it needs to be manually removed for cleaning, which is very inconvenient. For this reason, we propose a new aerator for sewage treatment. Utility Model Content

[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] The purpose of the utility model is to provide a novel aerator for sewage treatment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of aerator for sewage treatment, comprising a main body, a top end of the main body is provided with an anti-fouling mechanism, and a bottom end side of the main body is connected with a connecting cover, the anti-fouling mechanism comprises an aeration chamber, and the top surface of the aeration chamber is provided with a diaphragm, the top surface of the diaphragm is adhered with an anti-fouling sheet, and the middle end of the bottom surface of the anti-fouling sheet is connected with a telescopic rod, the bottom end of the telescopic rod is connected with a linkage rod, and sealing sheets are fixedly connected around the linkage rod, and paddles are provided on the top of the sealing sheet.

[0007] Furthermore, the membrane forms a telescopic structure with the aeration chamber through a linkage rod, and the middle ends of the blades and the sealing sheet are fixedly connected to the linkage rod.

[0008] Furthermore, the sealing sheet is connected to the elastic structure at the bottom of the aeration chamber through a telescopic rod and a spring.

[0009] Furthermore, the main body includes an aeration end head, and a ring cover is arranged at the top of the aeration end head, the inner walls around the ring cover are fitted with threaded grooves, and an inflation pipe is connected to one side of the bottom end of the aeration end head, and one end of the inflation pipe is connected to a connection cover.

[0010] Furthermore, the inflation pipe is fixedly connected to the aeration end head, and the ring cover forms a detachable structure with the top end of the aeration end head through the threaded groove.

[0011] Furthermore, the connection cover includes a cover body, and a rubber ring is attached to the inner wall of one end of the cover body, one side of the rubber ring is provided with an internal thread, and one end of the cover body is connected to the main body.

[0012] Furthermore, the rubber ring fits tightly along the inner wall of one end of the cover body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The aerator uses an anti-fouling sheet attached to the top membrane of the aeration chamber to prevent the accumulation of sediment in the sewage pool and blockage of the membrane surface. When in use, as the air is pressurized and replenished through the inflation pipe, the sealing sheet will drive the linkage rod to lift and force the anti-fouling sheet to lift synchronously, thereby realizing the normal aeration process, forming a situation where it is open during aeration and closed when not in use. In addition, the paddle blades rotate under pressure to break up the bubbles generated by the accumulated water stored in the chamber, effectively preventing the accumulation of dirt and the clogging of the aeration micropores by internal bubbles.

[0015] The top of the aeration end of this aerator is fixed with a ring cover and a threaded groove. The positioned diaphragm can be replaced by simply screwing the ring cover, which is convenient and quick. The aeration end as a whole cooperates with the inflation pipe to keep the aeration process stable.

[0016] In this device, the aeration end is connected to the air inlet pipe structure through a cover body to maintain stability, and the inner wall of the connecting part of the cover body is made of rubber ring material, which can effectively block the overflowing gas and maintain the stability of the air inlet aeration process.

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] The utility model provides Figure 1-4 A novel aerator for sewage treatment shown in the figure comprises a main body 1, a top end of the main body 1 is provided with an anti-fouling mechanism 2, and a bottom end side of the main body 1 is connected with a connection cover 3, the main body 1 comprises an aeration end 101, and a top end of the aeration end 101 is provided with a ring cover 102, the inner wall around the ring cover 102 is fitted with a thread groove 103, and a bottom end side of the aeration end 101 is connected with an inflation tube 104, and one end of the inflation tube 104 is connected with the connection cover 3;

[0028] In order to facilitate the replacement of the diaphragm 202 after long-term use, Figure 1As shown, the top portion of the aeration end 101 of the aerator is connected and fixed by a ring cover 102 in cooperation with a threaded groove 103. The positioned diaphragm 202 can be replaced by simply screwing the ring cover 102, which is convenient and quick. The aeration end 101 as a whole cooperates with the inflation tube 104 to maintain a stable aeration process.

[0029] like Figure 2-3 As shown, the anti-fouling mechanism 2 includes an aeration chamber 201, and a membrane 202 is provided on the top surface of the aeration chamber 201, an anti-fouling sheet 203 is attached to the top surface of the membrane 202, and a telescopic rod 204 is connected to the middle end of the bottom surface of the anti-fouling sheet 203, and a linkage rod 205 is connected to the bottom end of the telescopic rod 204, and a sealing sheet 206 is fixedly connected around the linkage rod 205, and a paddle 207 is provided on the top of the sealing sheet 206;

[0030] In order to improve the stability of use, such as Figure 2-3 As shown, this aerator can prevent the surface of the diaphragm 202 from being blocked by the accumulation of sediment in the sewage pool due to long-term use by fitting the anti-fouling sheet 203 at the top diaphragm 202 of the aeration chamber 201. When in use, as the air is pressurized and replenished through the inflation tube 104, the sealing sheet 206 will drive the linkage rod 205 to rise, forcing the anti-fouling sheet 203 to rise synchronously, thereby realizing the normal aeration process, forming a situation where it is opened during aeration and closed when not in use, and cooperates with the paddle 207 to rotate under pressure to break up the bubbles generated by the accumulated water stored in the cavity, effectively avoiding the accumulation of dirt and the blocking of the aeration pores by internal bubbles.

[0031] like Figure 4 As shown, the connection cover 3 includes a cover body 301, and a rubber ring 302 is attached to the inner wall of one end of the cover body 301, an internal thread 303 is arranged on one side of the rubber ring 302, and one end of the cover body 301 is connected to the main body 1;

[0033] In summary, when the environmentally friendly aerator is in use, the internal thread 303 at one end of the cover body 301 can be connected and fixed to the end of the air intake pipe structure, and then air can be taken in. When the pressurized gas enters the aeration chamber 201 through the inflation tube 104, the air pressure breaks open the blocked sealing piece 206. At this time, the sealing piece 206 is lifted upward, and the linkage rod 205 and the telescopic rod 204 integrated with the sealing piece 206 are lifted together. The telescopic rod 204 drives the anti-fouling sheet 203 at the top to open together, and then the gas is discharged through the micropores in the diaphragm 202 for the aeration process. When not in use, the pressurized gas is intermittent, and the sealing piece 206 is reset by the spring connected to the bottom end driving the telescopic rod 204, and then the bottom surface of the anti-fouling sheet 203 is closed again with the top surface of the diaphragm 202.
