[0002] A sewage suction truck is a new type of sanitation vehicle for cleaning, collecting, and transferring sludge and sewage to avoid secondary pollution. The sewage suction truck can self-prime and self-discharge, with a fast working speed, large capacity, and convenient transportation. It is suitable for collecting and transporting liquid substances such as feces, slurry, and crude oil. At present, domestic sewage suction trucks generally use sewage suction truck vacuum pumps, which have large suction force and long suction range, and are especially suitable for sucking, transporting, and discharging the silt in sewers. In particular, they can suck larger objects such as sewage sludge, silt, stones, and bricks in sewers.

[0003] Most of the dirt absorbed by the sewage suction truck is a solid-liquid mixture. Therefore, solid-liquid separation is required to achieve the compression and collection of dirt and improve the collectable amount. However, the current centrifugal filter cartridge still has the following problems in use:

[0030] 1) Sludge can be continuously added into the interior of the fixed cylinder 17 through the feed pipe 6;

[0031] 2) The sludge is pushed into the interior of the centrifugal filter cylinder 13 through the driving scroll blade 16. Then, the driving motor 10 drives the driving gear 11 to rotate, and then drives the driven gear ring 12 to rotate, thereby driving the centrifugal filter cylinder 13 to rotate at a high speed, so that the sludge inside the centrifugal filter cylinder 13 is quickly centrifuged to throw out water, dehydrating the sludge;

[0032] 3) Then, the deceleration motor 4 drives the driving scroll blade 16 to push the dehydrated sludge on the inner wall of the centrifugal filter cylinder 13 upward for automatic discharge. Thus, sludge can be continuously added and continuously discharged, enabling continuous dehydration of the sludge and improving the sludge suction efficiency.

[0033] In summary, for the centrifugal filter cylinder of this sewage suction truck, the driving motor 10 drives the driving gear 11 to rotate, then drives the driven gear ring 12 to rotate, thereby driving the centrifugal filter cylinder 13 to rotate at a high speed, so that the sludge inside the centrifugal filter cylinder 13 is quickly centrifuged to throw out water, dehydrating the sludge. At the same time, sludge can be continuously added through the feed pipe 6. Meanwhile, the deceleration motor 4 drives the driving scroll blade 16 to push the dehydrated sludge on the inner wall of the centrifugal filter cylinder 13 upward for automatic discharge. Thus, sludge can be continuously added and continuously discharged, enabling continuous dehydration of the sludge and improving the sludge suction efficiency. With the centrifugal filter cylinder 13 arranged obliquely upward, when discharging the sludge, the water can automatically fall by gravity, improving the dehydration effect.
