Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production, and in particular relates to a dust removal device for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, mixed with water in a certain proportion and obtained by mixing. It is also called ordinary concrete. It is widely used in civil engineering. A large amount of dust will be generated during the production process, and the dust-containing gas needs to be filtered through a dust removal device.

[0003] Nowadays, most dust removal devices used in concrete production have simple structures, and filter plates or filter cartridges are used for internal filtration. After a period of use, a large amount of dust will adhere to the surface of the filter plate or filter cartridge, resulting in a decrease in filtration efficiency. In addition, the filter plate or filter cartridge does not have an automatic cleaning function, and needs to be cleaned manually, which is very inconvenient.

[0004] Therefore, a dust removal device for concrete production is proposed. Utility Model Content
