Description

Technical Field

[0001] This utility model relates to the field of jet aerators, specifically to a Carrousel-type oxidation ditch jet aerator. Background Technology

[0002] Jet aerators are common devices in water treatment, primarily used to increase dissolved oxygen levels in water, improving water quality and the aquatic environment. A Chinese patent (CN 207957896 U) discloses a Carrousel oxidation ditch employing jet aeration. This patented technology solves the problem of activated sludge deposition and improves the treatment capacity of the Carrousel oxidation ditch. However, the influent ammonia nitrogen levels consistently exceed the discharge standards, and the existing oxidation ditch aeration system suffers from insufficient oxygen supply, affecting ammonia nitrogen treatment efficiency. Furthermore, the high flow velocity in the aerobic section of the oxidation ditch makes it impossible to install the jet aerator at the bottom of the tank. Therefore, those skilled in the art have developed a Carrousel-type oxidation ditch jet aerator to address the problems mentioned in the background. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a Carrousel-type oxidation ditch jet aerator, including a jet aerator, a jet aerator head, a seamless steel pipe air inlet pipe, a nozzle, a throat pipe, and a steel structure basket. The jet aerator is connected to and installed with the jet aerator head. The seamless steel pipe air inlet pipe is installed on the upper side of the jet aerator head. The nozzle is installed inside the jet aerator head. The throat pipe is welded to the side end of the jet aerator head. The jet aerator is installed in the middle position of the steel structure basket by a crane.

[0004] Preferably, a base plate is installed at the bottom of the steel structure suspended platform, a reinforcing plate is installed at the top corner of the steel structure suspended platform, and a crane assembly is installed at the middle position of the top of the steel structure suspended platform;

[0005] Preferably, the jet aerator has a fixed base installed at the bottom and two rotating seats installed at the top, with the rotating seats corresponding to the No. 1 rotating frame and the No. 2 rotating frame respectively.

[0006] Preferably, the top of the first rotating frame is equipped with a hanging groove, and the top of the second rotating frame is equipped with a hanging block, which can be inserted into the hanging groove;

[0007] Preferably, a No. 1 connecting plate is installed on the side of the jet aerator, and a No. 2 connecting plate is installed on the side wall of the jet aerator head. The No. 1 connecting plate and the No. 2 connecting plate are fixedly installed by fixing bolts. A fixing ring plate is welded to the inner side wall at the junction of the jet aerator head and the No. 2 connecting plate. The fixing ring plate is installed on the side of the nozzle, and a diffuser is installed at the end of the throat.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. The rotating base is equipped with rotating frame No. 1 and rotating frame No. 2 respectively. The top of rotating frame No. 1 is equipped with a hanging groove, and the top of rotating frame No. 2 is equipped with a hanging block. The hanging block can be inserted into the hanging groove, making assembly quick and effective.

[0010] 2. This design uses a steel structure suspended platform for installation, with an installation depth of 2 meters. The steel structure suspended platform is self-manufactured, with the main body made of C100×50 channel steel and the platform itself made of C50×30 channel steel. A 10 mm steel plate is welded to the bottom. The jet aerator is installed using a crane, which avoids the risk of it being washed away due to the high flow velocity.

[0011] 3. Based on the structure and operating characteristics of the oxidation ditch, this design selects the jet aerator scheme after extensive research and comparison. The jet aerator uses the negative pressure generated by the high-speed jet to draw in air. Through processes such as mixing, diffusion, and dissolution, it transfers oxygen from the air into the water to achieve the purpose of aeration, thereby improving the effect of ammonia nitrogen treatment. The jet aerator has a simple structure, is easy to maintain, is inexpensive, and has the dual effects of aeration and propulsion, which is very suitable for the operating characteristics of the oxidation ditch.

Example

[0019] Please see Figures 1-5 This embodiment provides a Carrousel-type oxidation ditch jet aerator, including a jet aerator 1, a jet aerator head 2, a seamless steel pipe air inlet pipe 4, a nozzle 5, a throat pipe 6, and a steel structure suspended basket 9. The jet aerator 1 uses a 7.5KW submersible sewage pump with a flow rate of 80m³. The jet aerator 1 is connected to and installed with the jet aerator head 2. The seamless steel pipe air inlet pipe 4 is installed on the upper side of the jet aerator head 2. The seamless steel pipe air inlet pipe 4 is made of 2m long 40Φ seamless steel pipe. The nozzle 5 is installed inside the jet aerator head 2. The nozzle 5 is composed of a 75Φ to 32Φ adapter welded to a 15cm long 75Φ seamless steel pipe. The throat pipe 6 is welded to the side end of the jet aerator head 2. The throat pipe 6 is made of 15cm long 75Φ seamless steel pipe. The jet aerator 1 is installed in the middle position of the steel structure suspended basket 9 by a crane.

[0020] Specifically, a base plate 901 is installed at the bottom of the steel structure suspended platform 9, a reinforcing plate 902 is installed at the top corner of the steel structure suspended platform 9, a crane assembly 903 is installed at the middle position of the top of the steel structure suspended platform 9, a fixed base 101 is installed at the bottom of the jet aerator 1, and two rotating seats 103 are installed at the top of the jet aerator 1. The rotating seats 103 are respectively installed with the first rotating frame 7 and the second rotating frame 8. The first rotating frame 7 is installed with a hanging groove 701 at the top, and the second rotating frame 8 is installed with a hanging block 801 at the top. The hanging block 801 can be inserted into the hanging groove 701.

[0021] A first connecting plate 102 is installed on the side of the jet aerator 1, and a second connecting plate 201 is installed on the side wall of the jet aerator head 2. The first connecting plate 102 and the second connecting plate 201 are fixedly installed by fixing bolts 3. A fixing ring plate 501 is welded and installed on the inner side wall at the junction of the jet aerator head 2 and the second connecting plate 201. The fixing ring plate 501 is installed on the side of the nozzle 5. A diffuser 601 is installed at the end of the throat pipe 6. The diffuser is composed of a 75Φ to 100Φ variable joint welded to a 20cm long 100Φ seamless steel pipe.

[0022] The working principle of this utility model is as follows:

[0023] During use, due to the fast flow velocity in the aerobic section of the oxidation ditch, the jet aerator 1 could not be installed at the bottom of the pool. After research, it was decided to use a steel structure suspended basket 9 for installation, with an installation depth of 2 meters. The steel structure suspended basket 9 was self-made, with the main body welded from C100×50 channel steel and the basket welded from C50×30 channel steel, with a 10 mm steel plate welded to the bottom. The jet aerator 1 was installed using a crane, which can avoid the risk of being washed away due to the fast flow velocity. After extensive research and comparison, the jet aerator 1 solution was selected. The jet aerator uses the negative pressure generated by the high-speed jet to draw in air, and through processes such as mixing, diffusion, and dissolution, it transfers oxygen from the air into the water to achieve the purpose of aeration, thereby improving the effect of ammonia nitrogen treatment. The jet aerator 1 has a simple structure, is easy to maintain, is inexpensive, and has the dual effects of aeration and propulsion, which is very suitable for the operating characteristics of the oxidation ditch.
