Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement conveying technology, and more specifically, to a cement conveying device. Background Technology
[0002] Cement is mainly used to manufacture building materials such as concrete, mortar, and cement bricks. Its main components include limestone, clay, and iron ore. These raw materials undergo grinding, mixing, and calcination processes to form cement clinker. After the cement clinker is transported to a mill and ground into powder, to improve the performance of the finished cement, auxiliary materials such as fly ash, slag powder, and gypsum are quantitatively mixed into it during the quantitative transportation of the cement clinker to the warehousing and bagging process, thus producing finished cement of different types and properties. Currently, conveying devices on the market utilize the rotational motion of spiral blades to propel materials along a trough. These devices are mainly suitable for non-agglomerated powdery, granular, and small lump bulk materials, such as cement.
[0003] In existing cement conveying devices, when cement materials are conveyed by a screw conveyor, the cement material adheres to the inner surface of the conveying cylinder, forming solidified residues that are difficult to clean. Moreover, the cement material entering the conveying device may contain lumps or large particles. If these materials are not crushed before entering the conveying cylinder, they will wear down and damage the screw conveyor blades and the inner wall of the conveying cylinder, affecting the service life of the conveying device. Therefore, it is necessary to develop a cement conveying device that can scrape and clean the materials adhering to the inner wall of the conveying cylinder and crush lumps or large particles.
