Description

a submersible mixer

technical field

The utility model relates to the field of sewage treatment, in particular to a mixer driven by a submersible motor.

Background technique

In the process of sewage treatment using the activated sludge method, the activated sludge is continuously stirred by the mixer to make the anaerobic microorganisms fully contact with the matrix and improve the treatment effect. Most of the mixers currently used in China, the motor is placed on the buoy, and the water impeller is placed in the water. The distance between the motor and the water impeller is relatively large, and the water impeller must be driven by an extended transmission shaft or a coupling. The transmission is unreliable; for some deep anaerobic pools, problems such as insufficient stirring at the bottom of the pool may occur, which affects the treatment effect; in addition, there are many parts, complex coordination, and high production, maintenance and processing costs , the machine is easily damaged, and the service life is short.

Utility model content

The problem to be solved by the utility model is to provide a submersible mixer to overcome the defects of low efficiency, complex structure and high maintenance cost in the prior art.

In order to achieve the above purpose, the utility model provides a submersible mixer, comprising a motor (5), a water impeller (3) matched with the motor (5), and a guide cylinder (2) covered outside the water impeller (3), located on The deflector (1) at the water outlet of the guide cylinder (2), the water impeller (3) is directly connected with the rotating shaft of the motor (5), and a trash rack (4) is arranged between the guide cylinder (2) and the motor (5).

Further, the motor (5) is an upright submersible motor, the upper end of which is connected with a mounting pipe (6), the upper end of the mounting pipe (6) is provided with a support plate (8), and the support plate (8) The lower surface is fixed with a buoy (7).

Further, fixed feet (9) are installed on the deflector.

Further, the deflector (1) is provided with several water outlets (10) evenly distributed around the circumference.

Further, there are six water outlets (10) on the deflector (1).

Compared with the prior art, the technical solution of the utility model has the following advantages: the water impeller is directly connected to the rotating shaft of the submersible motor, which shortens the distance of the transmission relationship between them, ensures reliable transmission, and can save energy consumption; Choose the installation method according to the actual situation, the scope of application is light, and it is convenient to use; there are few parts, the structure is simple, the installation and maintenance are convenient, the production and processing costs are reduced, and the service life is improved.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

The structural diagram of the utility model embodiment 1 is shown in Figure 1. The submersible mixer is composed of a motor 5, a water impeller 3, a guide cylinder 2, a trash rack 4 and a deflector 1. The motor here is a submersible motor, and the vertical place. The water impeller 3 is directly connected to the shaft head of the motor 5 shaft, and is located in the guide cylinder 2 at the same time. The lower end of the submersible motor 5, that is, the power output direction, is installed with a trash rack 4 connected by a flange, and the trash rack 4 The other end is connected with the guide cylinder 2 through another flange. The water outlet end of the guide cylinder 2 and the bottom of the deflector 1 are provided with fixed feet 9 .

When in use, the mixer is placed in an appropriate position of the treated water, the fixed feet can be fixed on the river bed, and the mixer can also be placed on the river bed by its own weight. When the submersible motor 5 is decorated, the main shaft drives the water impeller 3 to rotate, and when the water impeller 3 rotates, a negative pressure is generated around the trash rack 4, and a large amount of sewage is sucked from the gap of the trash rack 4, and then passes through the guide cylinder 2, diversion Device 1 is discharged. The sewage continuously discharged from the deflector 1 has a certain flow rate, which drives the surrounding activated sludge to move, so that the activated sludge in the pool is always in a state of turning, ensuring a good anaerobic treatment effect.

The structure schematic diagram of embodiment 2 of the present utility model is shown in Figure 2, differs from embodiment 1 in that: the upper end of motor 5 is connected with installation pipe 6, and the upper end of this installation pipe 6 is provided with support plate 8, and support plate 8 fixed on the buoy 7. During use, the agitator is limited to a certain position in the water by the buoyancy of the buoy 7. All the other structures of this embodiment are the same as Embodiment 1.

The water impeller of the utility model is directly connected to the rotating shaft of the submersible motor, which shortens the distance of the transmission relationship between them, ensures reliable transmission, and can save energy consumption; the installation method can be selected according to the actual situation, the application range is wide, and it is convenient to use; The parts are few, the structure is simple, the installation and maintenance are convenient, the production and processing costs are reduced, and the service life is improved.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
