Description

Vertical Submersible Aeration Mixer

technical field

The utility model belongs to the field of sewage treatment and relates to sewage treatment equipment, in particular to a vertical submersible aeration mixer. the

Background technique

At present, the submersible aeration mixer with the function of both aeration and mixing, which is applied in the occasions of urban domestic sewage treatment, industrial wastewater treatment and fish pond oxygenation, adopts the bottom of the mixing chamber to enter the water, and the upper part to enter the air. , The surrounding tangential water outlet mode has the disadvantages of low aeration efficiency, poor mixing effect, complex structure, and easy blockage of the water inlet. Therefore, there is a need for a submersible aeration mixer with high aeration efficiency, good mixing effect, simple structure, and no clogging of the water inlet. the

Contents of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, to provide a kind of water inlet from the upper part, air inlet from the bottom of the mixing chamber, and the peripheral mixed flow oblique water outlet mode, which has high aeration efficiency and good stirring effect, and has a simple structure and no water inlet. Vertical submersible aerated mixers that can clog. the

The technical scheme adopted by the utility model: mainly includes a submersible motor, a tripod, an impeller, a diversion cover, a mixing chamber and an intake cover, and is characterized in that the submersible motor is vertically fixed on the diversion cover through the tripod, and the submersible The protruding shaft head of the motor faces downward, and the impeller is fixed on the protruding shaft head of the submersible motor; the shroud is fixed on the mixing chamber with supporting legs, the air inlet cover is fixed in the mixing chamber, and the bottom of the mixing chamber is provided with an air inlet hole , there are a plurality of oblique flow channel holes evenly distributed around the gas mixture chamber. the

Generally, the utility model vertical submersible aeration mixer is composed of a submersible motor, a tripod, an impeller, a shroud, a mixing chamber, an air intake pipe, an air intake cover, and an air intake hose. The impeller is fixed on the extension shaft head of the submersible motor, and the extension shaft head of the submersible motor faces downward, and is vertically fixed on the shroud through a tripod, and the shroud is fixed on the mixing chamber with supporting legs, and the air intake The cover is fixed in the mixing chamber, one end of the air inlet pipe is connected to the air inlet hole at the bottom of the mixing chamber, the other end is connected to the air inlet hose, and the other end of the air inlet hose is connected to the Roots blower or air compressor. The oblique channel hole, the bottom of the mixing chamber has three supporting legs, which are supported on the bottom of the sewage pool. the

The utility model has the dual-purpose function of one machine. The first function is the aeration function. When the air intake pipe is connected to the Roots blower through the hose, the Roots blower will send the air through the pipe from the bottom of the vertical submersible aeration mixer into the air intake hood and then send it into the mixing chamber. The impeller rotates in the mixing chamber. On the one hand, the impeller cuts the air into small bubbles, which are fully mixed with the water entering the mixing chamber from the upper part of the shroud. At the same time, the impeller ejects the gas-liquid mixture from the oblique channel holes around the mixing chamber. In this way, the tiny air bubbles are evenly filled into the liquid for aeration, which increases the contact between the gas-liquid two-phase surface and improves the efficiency of the aeration system. The large exchange area formed in this way and the high turbulence of the ejected gas-liquid jet flow, It can greatly improve the oxygen transfer rate and oxygenation amount, that is, the aeration efficiency is high and the stirring effect is good. The second function is the stirring function. If the Roots blower is turned off and only the vertical submersible aeration mixer is turned on, the vertical submersible aeration mixer will only perform the stirring function. The vertical submersible aeration mixer can also be used as a special mixer, and there is no air intake pipe when used as a special mixer. the

The utility model has a unique operating mode of upper water intake, bottom air intake, and oblique peripheral water outlet, so that the air is easily cut into tiny bubbles by the rotating impeller and fully mixed with water, which greatly improves the aeration efficiency, and the water inlet and outlet will not clogged. the

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model. the

Detailed ways

Below in conjunction with specific accompanying drawing and embodiment the utility model is further described. the

Embodiment, the structure of this embodiment is shown in Figure 1, mainly including submersible motor 1, tripod 2, impeller 3, shroud 4, mixing chamber 5, air intake cover 6, air intake pipe 7, air intake hose 8; The impeller 3 is mounted on the lower part of the submersible motor 1, the submersible motor 1 is fixed on the tripod 2, the tripod 2 is fixed on the upper part of the shroud 4, the shroud 4 is fixed on the upper part of the mixing chamber 5, and the lower part of the mixing chamber 5 has three supports There are a plurality of oblique flow channel holes distributed around the mixing chamber 5, and there is an air inlet at the center of the bottom of the mixing chamber 5. One end of the air inlet pipe 7 is connected with the air inlet at the bottom of the mixing chamber 5, and the other end is connected with the air inlet hose 8. Air intake cover 6 is installed in mixing chamber 5 inner bottoms, and relies on mixing chamber 5 lower ends to carry three support legs to be placed on the bottom of the sewage pool after the complete machine is assembled. the

When the utility model is in use, it is placed at the bottom of the sewage pool. When the external Roots blower or air compressor (not shown) is started, the air will pass through the intake hose 8 and the intake pipe 7, from the center of the bottom of the mixing chamber 5 The air inlet hole is sent into the air intake cover 6 fixed on the bottom end of the mixing chamber 5, and the air escapes from the annular gap set at the lower end of the conical body of the air intake cover 6 and the bottom end of the mixing chamber 5. At this time, due to the impeller 3 Driven by the submersible motor 1, it rotates in the shroud 4. On the one hand, the impeller 3 cuts the air into small bubbles, which are fully mixed with the water entering the mixing chamber 5 from the upper part of the shroud 4. At the same time, the impeller 3 converts the gas-liquid mixture It is sprayed out from the oblique channel holes around the mixing chamber 5. In this way, the tiny air bubbles are evenly integrated into the water for aeration, which increases the contact between the gas-liquid two-phase surface, improves the efficiency of aeration, and at the same time acts as agitator to prevent sludge sedimentation in the pool. But when the external Roots blower or air compressor (not shown) shut down, the vertical submersible aeration mixer of the present utility model only plays a stirring role. the
