Description

Technical Field

[0001] The utility model relates to the technical field of cement manufacturing, in particular to dust removal equipment for cement manufacturing. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material, which becomes a slurry when mixed with water. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime pozzolana cement. It is used to bond concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. It is widely used in civil construction, water conservancy, national defense and other projects.

[0003] During the cement manufacturing process, some cement will come into contact with the working environment during transportation. The cement will be shaken during transportation, which will cause some lime in the cement to vibrate and then produce dust. This dust will float in the air and pollute the working environment.

During use, the bags are often clogged, resulting in low dust removal efficiency and poor dust removal effect. The filtered cement is easy to clog the discharge port when discharged, resulting in poor discharge and inconvenient use. Utility Model Content
