Description

Technical Field

[0001] The utility model belongs to the technical field of bulk cement conveying devices, and specifically relates to a bulk cement conveying device. Background Art

[0002] Cement is a powdery hydraulic inorganic binder, which is widely used in civil engineering, water conservancy and other projects. Bulk cement refers to cement that meets the national cement standards and is directly produced, transported, stored and used through reusable special containers and special transportation tools without using disposable packaging bags.

[0003] At present, most use a cement screw conveyor to convey bulk cement. By putting the cement into the feed inlet of the screw conveyor, the spiral inside the machine body rotates to drive the bulk material to rise or fall along the spiral line for transportation, so as to achieve the purpose of long-distance and continuous cement transportation.

[0004] Due to the influence of storage conditions, loading, unloading and transportation factors, there will inevitably be large lumps or impurities in the bulk cement. During the transportation process, these lumps or impurities are likely to get stuck between the spiral blades of the screw conveyor, increasing the resistance of the material during transportation, causing the device to clog, thus interrupting the transportation process and even damaging the equipment.
