Furthermore, a supporting table is fixed at the lower end of the sleeve, and the lower end of the stirring propeller is pressed on the top of the supporting table.

Further, the upper ends of the guide rods are exposed outside the sedimentation tank and extend above the bridge main body.

Furthermore, a chain is fixed at the top of the motor, and the upper end of the chain is fixed on the bridge frame main body.

Use the utility model provides a peripheral transmission mud scraper of area stirring propeller, its beneficial effect is: after the chemicals are added into the sedimentation tank, the stirring blades of the stirring propeller can fully stir the chemicals when working, and the solid suspended matters in the inlet water can be efficiently removed under the condition of short hydraulic retention time; sliding fit about stirring propeller's sleeve and the guide arm, the convenience is put into the sedimentation tank with stirring propeller, also conveniently takes out stirring propeller from the sedimentation tank.

Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

as shown in fig. 1 and 2, a peripheral transmission mud scraper with a stirring propeller comprises a sedimentation tank 1 and a bridge frame 2, wherein a central upright post 11 is arranged at the center of the sedimentation tank 1, a driving device 3 is fixed at the top of the central upright post 11, the driving device 3 is connected with the bridge frame 2, the bridge frame 2 comprises a bridge frame main body 21 exposed out of the sedimentation tank 1 and a truss 22 fixed at the bottom of the bridge frame main body 21 and extending into the sedimentation tank 1, a guide rod 4 extending up and down is fixed on the truss 22, the stirring propeller 5 is sleeved outside the guide rod 4, the stirring propeller 5 comprises a motor 51, and a stirring blade 52 and a sleeve 53 which are respectively arranged at the front end and the rear end of the motor 51, and the sleeve 53 is sleeved outside the guide rod 4 and is in up-down sliding fit with the guide rod 4. The number of the guide rods 4 is two, and the number of the stirring propellers 5 is also two.

The driving device 3 is connected with the middle position of the bottom of the bridge main body 21, the driving device 3 is preferably a motor driving device, and the driving device 3 can drive the whole bridge 2 to rotate when in work.

As shown in fig. 2, in order to support the stirring propeller 5, a support base 6 is fixed to the lower end of the sleeve 53, and the lower end of the stirring propeller 5 is pressed against the top of the support base 6.
