a packing auger (33); the packing auger (33) is fixedly connected to an output shaft of the motor (32);
a feed pipe (34); the feeding pipe (34) is fixedly connected with the outer wall of the material conveying pipe (31) and is communicated with the interior of the material conveying pipe (31).
5. A sludge treatment system according to claim 4, characterized in that: the partition plate (23) is fixedly connected with a plurality of anti-slip strips (231); the anti-skid strips (231) are transversely arranged.
6. A sludge treatment system according to claim 5, characterized in that: a gap is reserved between the upper edge of the partition plate (23) and the top plate (24);
the upper edge of baffle (23) has linked firmly cutter (232), cutter (232) remove the in-process and can cut the material.
7. A sludge treatment method applied to the sludge treatment system according to claim 6, characterized in that: the method comprises the following steps:
s1: firstly, sludge is concentrated, tempered, dehydrated and dried by processing equipment and finally incinerated, a worker controls a material conveying assembly (3) to convey materials into a combustion shell (2) through a controller, the controller controls an igniter in an incineration ring (1) to ignite, so that combustion is carried out under the action of the igniter, and finally materials in the combustion shell (2) are driven by kindling to combust;
s2: the combustion shell (2) and the incineration ring (1) are internally and upwardly exhausted by airflow generated during combustion, so that the airflow impacts the blades (26) to provide a driving force for the blades (26), the blades (26) drive the rotary ring (25) to rotate on the incineration ring (1), the rotary ring (25) after rotation drives the annular shell (22) to rotate through the connecting rod (27), and the annular shell (22) rotates to drive the partition plate (23) to stir in the annular shell (22);
s3: the partition plate (23) cuts the material which just enters the bottom shell (21), then the material is shoveled from the bottom of the annular shell (22), along with the shoveling of the partition plate (23), the material is shoveled onto the end face of the partition plate (23) and moves along the end face of the partition plate (23), and the material is impacted by the anti-slip strips (231) on the partition plate (23) to form secondary crushing;
s4: after the materials are shoveled by the partition plates (23) and move along the inclined planes of the partition plates (23), the materials can move close to the top plate (24), and are discharged along the gap between the top plate (24) and the partition plates (23), the materials are cut again by the cutter (232), and the materials discharged from the gap fall on the next partition plate (23) under the action of gravity and collide with the anti-slip strips (231) on the partition plates (23), so that the materials can shuttle back and forth and collide among the partition plates (23); the partition plate (23) scrapes dust on the surface of the burning ring (1) in the rotating process, and the burned dust can be discharged by being driven by airflow through meshes on the burning ring (1).
