Technical field

This utility model relates to liquid processing technique field, is specifically related to a kind of agitator.

Background technology

Mixed liquor is adding man-hour, typically require and utilize agitator to be stirred, to guarantee that liquid fully mixes, existing agitator usually includes tank body, shaft and drive motor, drive motor is utilized to drive shaft, rotating in the stirring vane on shaft mixed liquor in tank body, drive mixed liquor motion, mixed liquor mixes in convection process.Existing agitator operationally, owing to stirring vane is to drive mixed liquor horizontal movement, therefore, is difficult to effectively form convection current between the mixed liquor of differing heights position, thus causing that the Blending Efficiency of Blending of liquid is poor.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of agitator, and it can make mixed liquor realize convection current in the height direction, promotes the effect of mixing.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of agitator, including tank body, upper cover, shaft and motor, the bottom of tank body is closed, upper end open, the top of what detachable upper cover unloaded be arranged on tank body is to cover the opening of tank body, shaft is articulated in and covers and extend in tank body, the bottom of shaft is provided with multiple stirring vane, and the body of motor is fixed on and covers, and the rotating shaft of motor is Tong Bu with shaft to be coupled；On cover the air outlet adapter being provided with the inlet suction port being connected with outside high-pressure air source and the inner space with tank body, upper interior surface is provided with a connecting tube, one end of this connecting tube is connected with inlet suction port, the other end of connecting tube is fixed on a ring flange being actively socketed on shaft, ring flange is provided with a radial hole turned on the other end of connecting tube, the inner surface of ring flange is provided with the pneumatic trough of a ring-type, being provided with a bottom on shaft and extend to the passage of shaft bottom, the top ends of passage connects with pneumatic trough.

Ring flange is fixed on the lower surface of upper cover, and the position that the inner surface of ring flange coordinates with shaft is provided with sealing ring.

The position that cover rim coordinates with tank body top is provided with gasket seal.

Upper cover is fixed together by bolt and tank body.

The beneficial effects of the utility model are in that:

Compared to prior art, this utility model does not drive mixed liquor advection merely with stirring vane, meanwhile, utilizes high pressure draught to drive mixed liquor in short transverse convection current, thus improve the Blending Efficiency of Blending of mixed liquor.

Detailed description of the invention

Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:

As shown in Figure 1, 2, for a kind of agitator of the present utility model, it includes tank body 10, upper cover 20, shaft 30 and motor 50, the bottom of tank body 10 is closed, upper end open, upper cover 20 is detachably arranged in the top of tank body 10 to cover the opening of tank body 10, and shaft 30 is articulated on upper cover 20 and extend in tank body 10, and the bottom of shaft 30 is provided with multiple stirring vane 31, the body of motor 50 is fixed on upper cover 20, and the rotating shaft of motor 50 is Tong Bu with shaft 30 to be coupled；Upper cover 20 is provided with the inlet suction port 41 being connected with outside high-pressure air source, and the air outlet adapter 42 of the inner space with tank body 10, upper cover 20 inner surface is provided with a connecting tube 43, one end of this connecting tube 43 is connected with inlet suction port 41, the other end of connecting tube 43 is fixed on a ring flange 44 being actively socketed on shaft 30, ring flange 44 is provided with a radial hole 442 turned on the other end of connecting tube 43, the inner surface of ring flange 44 is provided with the pneumatic trough 441 of a ring-type, shaft 30 is provided with a bottom and extends to the passage 32 of shaft 30 bottom, the top ends of passage 32 connects with pneumatic trough 441.

Above-mentioned agitator of the present utility model is operationally, stirring vane 31 rotates under the drive of motor 50 along with shaft 30, the convection current of the mixed liquor level in drive tank body 10, simultaneously, gases at high pressure are successively from inlet suction port 41, connecting tube 43, radial hole 442, pneumatic trough 441, passage 32 stream is to the position of tank body 10 central bottom, gas forms the air-flow risen in tank body 10, the air-flow of this rising makes mixed liquor have the trend flowed up and down, so that the mixed liquor of differing heights position carries out convection current, so, this utility model does not drive mixed liquor advection merely with stirring vane 31, simultaneously, high pressure draught is utilized to drive mixed liquor in short transverse convection current, thus improve the Blending Efficiency of Blending of mixed liquor；Gases at high pressure are reaching after more than liquid level, discharge via air outlet adapter 42.

In this utility model, it is possible to be the lower surface that ring flange 44 is fixed on upper cover 20, in order to prevent gas leakage, the position that the inner surface of ring flange 44 coordinates with shaft 30 is provided with sealing ring.

When the mixing liquid special for some is stirred, prevent the composition in mixed liquor from producing chemical reaction with air, may also be and utilize noble gas to form said flow, certainly, for this noble gas, in order to prevent it from revealing, it is possible to the position coordinated with tank body 10 top at upper cover 20 edge is provided with gasket seal, in order to ensure sealing effectiveness easy disassembly simultaneously, upper cover 20 can be through bolt and is fixed together with tank body 10.

It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims.
