Example (b):

as shown in figures 1-3, the utility model provides a denitrification system excess sludge pump station, which comprises a denitrification system 2 and an oxidation ditch 1. The oxidation ditch 1 is communicated with the denitrification system 2 through a conveying pipe 3. The delivery tube 3 is provided with a pumping assembly 4. The sludge generated in the denitrification system 2 can be conveyed into the oxidation ditch 1 through the pumping assembly 4.

The utility model discloses a when denitrification system excess sludge pump station used, the mud in 4 with denitrification system 2 of pump sending directly takes out to oxidation ditch 1 in, simplifies the flow, avoids the trouble and the energy waste that repeated extraction brought.

In this embodiment, the pumping assembly 4 includes a delivery pump and a number of impeller assemblies 41. The delivery pump is used for pumping the sludge, and then pumping the sludge into the oxidation ditch 1 from the inside of the denitrification system 2. A plurality of plug flow assemblies 41 are evenly distributed along the duct 3. The plug flow assembly 41 comprises a delivery vane 411 arranged inside the delivery tube 3. When the conveying blade 411 rotates, the sludge in the conveying pipe 3 moves forward by the rotation of the conveying blade 411. The conveying blade 411 can give a certain thrust to the sludge. When the conveying distance is long and the conveying force of the conveying pump is insufficient, the sludge can be well conveyed into the oxidation ditch 1 by the rotation of the conveying blades 411. This just makes the utility model discloses a sludge pump station can be applicable to the sludge of longer distance and carry.

In this embodiment, the pumping assembly 4 further includes a conveying motor 42 and an annular seat 43. The conveying blade 411 is disposed inside the seat body 43. The seat 43 is driven by the conveying motor 42 to rotate, i.e. the conveying blade 411 can be driven to rotate. The delivery pipe 3 is further provided with a guide groove 31 in cooperation with the seat body 43. The holder body 43 is installed in the guide groove 31 such that the holder body 43 is restricted in the guide groove 31 and is also rotatable in the guide groove 31. The outer wall of the holder body 43 is provided with a rotation tooth 431 along its circumference. The conveying motor 42 is disposed in the guide groove 31. The transfer motor 42 is connected to a transfer gear 44. The transmission gear 44 is engaged with the transmission gear 44.

The conveying motor 42 can drive the conveying blade 411 to rotate through the transmission gear 44. The driving assembly is not arranged inside the conveying pipe 3, so that the driving assembly is prevented from being arranged in the conveying pipe 3 to influence the flowing of the sludge, and the sludge conveying is smoother and more efficient. Meanwhile, the driving assembly is prevented from being polluted by the sludge because of being arranged in the conveying pipe 3.

In this embodiment, the inner diameter of seat 43 is the same as the inner diameter of delivery pipe 3. The inner wall of seat 43 is flush with the inner wall of duct 3. This makes the conveyer pipe 3 inner wall more level and more smooth and easy high-efficient of carrying.

In this embodiment, a sealing ring 432 is disposed between the seat body 43 and the groove wall of the guide groove 31. This effectively prevents the sludge in the conveying pipe 3 from entering the guide groove 31 to affect the driving motor and other parts.

In this embodiment, a group of plug flow assemblies 41 is provided for each 10m of the conveying pipe 3. Make the utility model discloses a sludge pump station can be applicable to the sludge of more remote and carry.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
