[0028] The working principle of this utility model:

[0029] Refer to the instruction manual Figure 1-Figure 5The utility model is provided with a feeding cylinder 1, a conveying cavity 2, a feeding ball 3, a first conveying screw 4, a hemispherical groove 5, a hemispherical shell 6, an inserting rod 7 and a feeding rack 8. The feeding cylinder 1 conveys the oil sludge, and the oil sludge is put into the conveying cavity 2. The first conveying screw 4 rotates to move the oil sludge in the conveying cavity 2 toward the feeding ball 3. As the oil sludge gradually moves toward the feeding ball 3, the feeding ball 3 is adjusted to rotate, and the hemispherical shell 6 of the hemispherical groove 5 and the conveying cavity 2 are connected. The first conveying screw 4 continues to convey the sludge forward, and the sludge is conveyed from the conveying chamber 2 to the inner side of the hemispherical shell 6. At this time, the feeding ball 3 remains stationary, and the sludge is squeezed into the hemispherical shell 6. The hemispherical shell 6 is pressed into the hemispherical groove 5. As the sludge is continuously conveyed to the feeding ball 3, the sludge is compacted inside the hemispherical shell 6. The inserted rod 7 inside the hemispherical shell 6 performs a perforation process on the compacted sludge, so that the compacted sludge inside the hemispherical shell 6 has a honeycomb structure, and the sludge is heated. After the sludge inside the hemispherical shell 6 is compacted, the feeding ball 3 is rotated and adjusted, and the hemispherical shell 6 containing the compacted sludge rotates with the feeding ball 3, and the hemispherical shell 6 without the sludge rotates with the feeding ball 3 at the same time. When the hemispherical shell 6 containing the compacted sludge rotates to the upper inner side of the feeding rack 8, the hemispherical shell 6 loses the blocking of the spherical cavity 12, and the hemispherical shell 6 falls downward under the gravity of the sludge, compacting the sludge. The sludge is dropped from the hemispherical shell 6 into the feeding rack 8, and then the compacted sludge is dropped from the feeding rack 8 to complete the feeding work. At this time, the hemispherical shell 6 without sludge inside moves to a position aligned with the conveying chamber 2, and the sludge continues to be conveyed forward. The sludge is compacted inside the new hemispherical shell 6. When the sludge is compacted, the feeding ball 3 can completely block the sludge, and the compaction force on the sludge is greater, and the compaction treatment effect of the sludge is better, which is convenient for subsequent pyrolysis treatment.

[0030] During the process of the hemispherical shell 6 being squeezed by the oil sludge, the hemispherical shell 6 moves toward the inside of the hemispherical groove 5, and the insert 9 moves with the hemispherical shell 6. The insert 9 is inserted into the inside of the support sleeve 10, and the spring 11 is compressed and deformed; when the hemispherical shell 6 moves to be connected with the feeding rack 8, the hemispherical shell 6 moves downward under the action of the gravity of the oil sludge, and the insert 9 moves outward from the inside of the support sleeve 10, and the spring 11 rebounds and stretches. After the oil sludge falls off from the inside of the hemispherical shell 6, the spring 11 contracts and rebounds to pull the hemispherical shell 6 upward, so as to facilitate the subsequent reset of the hemispherical shell 6 back to the inside of the hemispherical groove 5.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
