Technical Field

[0001] The present invention relates to the technical field of drum lifting plates, and particularly to a drum lifting plate structure. Background Art

[0002] The common drum lifting plate structure in the asphalt production industry is the traditional box-type integrated lifting plate structure, which not only has low heating efficiency but also slow stone conveying speed.

[0003] For example, on September 7, 2011, a patent with the publication number CN101458045B and the name of an isothermal lifting plate structure drum slag cooler was published, including a rotating drum. The rotating drum includes an inner cylinder and an outer cylinder. The annular cavity between the inner cylinder and the outer cylinder is filled with cooling water. A plurality of lifting plate structures are arranged on the inner wall of the inner cylinder. The plurality of lifting plate structures are arranged in a spiral shape from one end of the inner wall of the inner cylinder to the other end. All the lifting plate structures in the rotating drum or only the lifting plate structures located in the high-temperature section of the rotating drum have internal cavities, and the internal cavities are communicated with the annular cavity between the inner cylinder and the outer cylinder. The heat transfer efficiency of this invention is significantly improved, the heat energy carried away is increased, and the lifting plate structure can increase the unfolding height, so the slag flow rate of the large-tonnage slag cooler is increased; however, the applicant found that it is difficult to ensure that the material is fully heated by setting the annular cavity, thereby reducing the processing efficiency. Summary of the Invention

[0005] Based on the above purpose, the present invention provides a drum lifting plate structure, including a simple shell. The simple shell is cylindrical. Along the axial direction of the simple shell, a first conveying section, a first lifting section, a second lifting section, and a second conveying section are sequentially arranged on the inner side wall of the simple shell. The first conveying section includes spiral plates arranged at equal angles on the inner side wall of the simple shell; the first lifting section includes multiple turns of first lifting members arranged along the axial direction of the simple shell. Each turn of the first lifting member includes a plurality of first scooping plates arranged at equal angles on the inner side wall of the simple shell, and the first scooping plates on adjacent two turns of the first lifting members are arranged staggeredly; the second conveying section includes multiple turns of conveying members arranged along the axial direction of the simple shell. Each turn of the conveying section includes a plurality of material conveying box plates arranged at equal angles on the inner side wall of the simple shell. The material conveying box plate includes a conveying box body. The conveying box body is hollow. Guide plates and retaining plates are respectively arranged on both sides of the conveying box body. The guide plate on the conveying box body faces the retaining plate on its adjacent conveying box body, and the two conveying box bodies are on the conveying members of the same turn.
