Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a dust collector for cement production. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bind sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime volcanic ash cement. It is used to bind 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. For a long time, it has been widely used as an important cementitious material in civil construction, water conservancy, national defense and other projects.

[0003] At present, cyclone dust collectors are commonly used. Cyclone dust collectors are a type of gas dust removal device. The dust removal principle is to make the dust-laden airflow rotate under the driving action of the fan of the previous process, and use centrifugal force to separate dust particles from the airflow and collect them on the wall of the device. Then, gravity makes the dust particles fall into the dust discharge hopper. The dust collector often has incomplete dust removal. A small amount of dust will still be discharged into the air with the airflow, resulting in poor dust collection effect and affecting the environment.

[0004] Therefore, a dust collector for cement production is proposed. Utility Model Content
