Description

A floating aeration device

technical field

The utility model relates to a floating aeration device, in particular to a floating aeration device with low noise, simple pipeline and low cost.

Background technique

Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. In addition, aeration also has the purpose of preventing the suspension of the tank from sinking and strengthening the contact between the organic matter in the tank, microorganisms and dissolved oxygen. In this way, the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.

At present, fan room + aeration pipeline treatment process is mostly used for water treatment aeration. The traditional aeration treatment process has disadvantages such as loud fan noise, complicated pipeline, expensive construction, and inconvenient operation and maintenance.

Contents of the invention

The technical problem to be solved by the utility model is to provide a floating aeration device with low noise, simple pipeline and low cost.

In order to solve the above technical problems, the technical solution of this utility model is: a floating aeration device, the innovation of which is: including floating brackets, buoys, water ejectors, submersible pumps, air pipes and diffusers, floating brackets The buoy is installed on the top, and the water ejector and submersible pump are installed at the lower end of the floating support. The water ejector includes a nozzle, a suction chamber and a diffuser pipe. The nozzle of the water ejector communicates with the outlet of the submersible pump. The nozzles are connected, the nozzle at the other end of the air pipe is located above the buoy, and the diffuser of the water ejector is connected with the diffuser.

Further, the axis of the diffuser pipe of the water ejector is arranged horizontally.

The utility model has the advantages that: the floating aeration device adopts a floating structure composed of floating brackets and buoys, which rises and falls with the increase of the water volume in the pool, and the work is not limited by the water volume. During aeration, the submersible pump is used to provide power, the compressed air is inhaled by the water injector and mixed with pressurized water, and then sprayed along the horizontal direction. , high dissolved oxygen rate, sufficient aeration, no fan room and complex air pipeline system in the blast aeration method, simple system, no clogging, no air filter device, stable operation, easy installation and maintenance. And because the equipment operates under water, the noise is small and the application range is wide.

Detailed ways

As shown in FIG. 1 , it includes a floating support 1 , a buoy 2 , a water ejector 3 , a submersible pump 4 , an air pipe 5 and a diffuser 6 .

A buoy 2 or a floating ball is installed on the top of the floating support 1 , and a water ejector 3 and a submersible pump 4 are installed on the lower end of the floating support 1 .

Water ejector 3 as shown in Figure 2, comprises nozzle 31, suction chamber 32 and diffuser pipe 33, the nozzle 31 that stretches into suction chamber is installed in the front end of suction chamber 32, the rear end of suction chamber 32 is connected in series with diffuser pipe, suction chamber 32 side A suction inlet is opened on the wall, and the diffuser pipe 33 is successively divided into a compression section, a throat section and a diffusion section from front to back. The water ejector nozzle 31 communicates with the water outlet of the submersible pump 4 , the water ejector suction chamber 32 communicates with one end of the air pipe 5 , and the diffuser 33 of the water ejector 3 is connected with the diffuser 6 .

The mouth of the other end of the air pipe 5 is located above the buoy 2 to ensure that when the aeration device is placed in the aeration tank, the mouth of the air pipe 5 is above the liquid level so that it can always supply air normally.

When the water ejector 3 is installed on the floating support 1, the axis of the diffuser pipe 33 of the water ejector 3 is arranged horizontally.

The structure of the diffuser 6 is shown in Figure 3, including a trumpet-shaped pipe body 61, the pipe body 61 has a built-in hollow or solid cone 62, the cone 62 is fixed by connecting the steel plate 63 to the inner wall of the pipe body 61, and the pipe body 61 The small end of the welding connection flange 64.

Wherein, the jet 3 and the diffuser 6 are made of corrosion-resistant materials, and the submersible pump adopts a mechanical seal, which is reliable in operation.

working principle:

During operation, the submersible pump 4 pushes the mud-water mixture into the water injector 3 to form a jet, and the suction chamber 32 at the outlet of the nozzle 31 generates a negative pressure zone, and the air is sucked into the negative-pressure zone of the jet through the air pipe 5, and the mud-water mixture is air-fed. , water, and mud are fully mixed, and the kinetic energy of the jet is gradually converted into pressure energy through the diffuser 33 of the water injector, and then enters the diffuser 6. In the diffuser 6, the mixture of gas, water and mud is further mixed, forcing the gas to continue shearing, pulverizing and emulsifying to ensure that most of the oxygen is fully dissolved in the water. At the same time, under the action of the fluid pressure of the jet, the jet carries oxygen molecules and micro-bubbles, which are ejected horizontally from the diffuser 6 and diffused to form an impact on the water body and stir, then slowly rise from the bottom of the pool to the water surface, and the micro-bubbles are The residence time in the water is more than 30 seconds, so that the oxygen in the air is fully dissolved and absorbed, which improves the oxygen transfer efficiency and oxygenation capacity, and achieves the effect of aeration.
