Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a deep aeration device. Background Technology

[0002] Industrial wastewater, including production wastewater, industrial sewage, and cooling water, refers to wastewater and waste liquid generated during industrial processes. This wastewater and waste liquid mainly contain industrial production materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Among these, aeration is a crucial treatment method. Aeration increases the saturated dissolved oxygen concentration of the mixed liquor, which is beneficial for the growth of microorganisms and the degradation of organic matter. In existing technologies, several pipes are usually installed in the aeration tank, and aeration components are installed on the pipes. Common aeration components mainly include disc aerators and tubular aerators.

[0003] A search revealed Chinese Patent Publication No. CN220376475U, which discloses a deep aeration treatment device for industrial wastewater. When the waste liquid enters the tank, the aeration components are activated. Since the aeration components are mainly composed of pipes, air pumps, and nozzles, the air pump installed on the tank is activated. The air pump transmits airflow into the pipes fixedly connected to the tank and communicating with the air pump. The airflow is then transmitted through the pipes into the nozzles that are fixedly connected to the pipes, thereby aerating the liquid in the tank.

[0004] However, in the prior art, aerators are usually fixed to pipes, which means that liquids far from the aerators cannot be fully mixed with the gas sprayed from the aerators. Utility Model Content

[0005] The purpose of this invention is to provide a deep aeration device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A deep aeration device includes a treatment tank. A U-shaped main pipe is installed in the treatment tank through several support components. Several branch pipes are fixedly connected between the main pipes. An air supply component is provided on one side of the main pipe. Multiple aeration components are installed on the top of the main pipe and the branch pipes. Each aeration component includes a connecting pipe. A U-shaped pipe is fixedly connected to the top of the connecting pipe. Two discs are fixedly connected to both ends of the U-shaped pipe. An air supply chamber is opened on the top of the disc. The disc communicates with the U-shaped pipe. An elastic membrane is fixedly connected to the top of the disc. Solenoid valves are provided in both branches of the U-shaped pipe. The two solenoid valves open and close alternately. Several levers are fixedly connected to the edge of the elastic membrane.

[0008] Preferably, there is an angle between the paddle and the tangent direction of the disc.

[0009] Preferably, the support assembly includes a mounting base, which is fixedly connected to the bottom of the treatment tank. A support rod is fixedly connected to the top of the mounting base, and a retaining seat is fixedly connected to the top of the support rod. The main pipe or branch pipe is retained in the retaining seat.

[0010] Preferably, the air supply assembly includes an air supply pipe, one end of which is fixedly connected to the main pipe and communicates with the main pipe, and the main pipe is also connected to the branch pipe. The other end of the air supply pipe extends out of the treatment tank and is fixedly connected to the air outlet of the air pump. The air supply pipe is fixedly connected to the tank wall of the treatment tank.

[0011] Preferably, the top of the main pipe and branch pipes are provided with several mounting holes, and the connecting pipe is threaded into the mounting holes.

[0012] Preferably, the elastic membrane is made of rubber.

[0013] Preferably, the card holder is U-shaped with the opening facing upwards.

[0014] The beneficial effects are as follows: A set of aeration components includes two discs, and air is intermittently supplied to the two discs, so that the elastic membrane at the top of each disc alternately indents inward and bulges outward. When the elastic membrane bulges outward or indents inward, it drives the paddle to move back and forth, promoting the flow of liquid near the aeration component and improving the uniform contact between liquid and gas.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a deep aeration device includes a treatment tank 1. A U-shaped main pipe 301 is installed in the treatment tank 1 through several support components. Several branch pipes 302 are fixedly connected between the main pipes 301. The support components include a mounting base 201, which is fixedly connected to the bottom of the treatment tank 1. A support rod 202 is fixedly connected to the top of the mounting base 201. A retaining seat 203 is fixedly connected to the top of the support rod 202. The retaining seat 203 is U-shaped with the opening facing upward. The main pipe 301 or the branch pipe 302 is engaged in the retaining seat 203.

[0027] An air supply assembly is provided on one side of the main pipe 301. The air supply assembly includes an air supply pipe 303. One end of the air supply pipe 303 is fixedly connected to the main pipe 301 and is connected to the main pipe 301. The main pipe 301 is also connected to the branch pipe 302. The other end of the air supply pipe 303 extends out of the treatment tank 1 and is fixedly connected to the air outlet of the air pump. The air supply pipe 303 is fixedly connected to the tank wall of the treatment tank 1 by a clamp.

[0028] Multiple aeration components are installed on the top of the main pipe 301 and the branch pipe 302. Each aeration component includes a connecting pipe 401. Several mounting holes are provided on the top of the main pipe 301 and the branch pipe 302. The connecting pipe 401 is threaded into these mounting holes. A U-shaped pipe 402 is fixedly connected to the top of the connecting pipe 401. Two discs 403 are fixedly connected to both ends of the U-shaped pipe 402. An air supply chamber is provided on the top of each disc 403. The disc 403 communicates with the U-shaped pipe 402. An elastic membrane 404 is fixedly connected to the top of the 3. The elastic membrane 404 is made of rubber. Solenoid valves 405 are installed in both branches of the U-shaped tube 402. The two solenoid valves 405 open and close alternately. Several paddles 406 are fixedly connected to the edge of the elastic membrane 404. There is an angle between the paddles 406 and the tangent direction of the disc 403, so that when the paddles 406 are moved, the liquid around the disc 403 forms a vortex, which further enhances the uniformity of liquid and gas mixing.

[0029] Working principle: During installation, firstly, several mounting bases 201 are fixed to the bottom of the treatment tank 1. Then, the main pipe 301 and branch pipes 302 are fixed to the mounting base 203. The connecting pipe 401 is screwed into the mounting holes opened at the top of the main pipe 301 and branch pipes 302. Air is supplied to the air supply pipe 303 by an air pump. The air supply pipe 303 delivers the gas to the main pipe 301 and branch pipes 302, and then enters the U-shaped pipe 402 through the connecting pipe 401. By controlling the two solenoid valves 405 in the U-shaped pipe 402, the gas is opened and closed alternately. When one solenoid valve 405 is opened, the gas is closed. When closed, air is intermittently supplied to the two discs 403, causing the elastic membrane 404 at the top of each disc 403 to alternately indent and bulge outward. When the elastic membrane 404 bulges outward or indents inward, it drives the paddle 406 to move back and forth, promoting the flow of liquid near the aeration component and improving the uniform contact between liquid and gas. There is an angle between the paddle 406 and the tangent direction of the disc 403, so that when the paddle 406 moves, the liquid around the disc 403 forms a vortex, further enhancing the uniformity of liquid and gas mixing.
