Description

Technical Field

[0001] This utility model relates to the field of dust recovery technology, and more specifically, it relates to a dust recovery and reuse device for a cement packaging line. Background Technology

[0002] Cement packaging lines generate a large amount of dust during production, which not only pollutes the environment but also poses potential health risks to workers. Therefore, dust recycling and reuse are crucial. Recycled dust can be reintroduced into the cement production process as a raw material. This not only reduces raw material consumption and lowers production costs but also protects the air quality and prevents pollution of the surrounding environment.

[0003] However, existing dust recovery devices only have the function of filtering dust, and the filtered dust is not easy to remove from the inside of the device, which affects the convenience of using the recycling device.

[0004] Furthermore, during cement production, the clinker is typically calcined at around 1450℃. After cooling at this high temperature, the clinker enters the subsequent grinding and packaging processes, but it may still contain dust at high temperatures. Existing recycling devices do not have a structure to cool down this dust, and prolonged use of high-temperature dust can affect the lifespan of the fans. Utility Model Content
