Description

Technical Field

[0001] The utility model relates to the technical field of powder recovery, in particular to a powder recovery device for bulk cement clinker. Background Art

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials in appropriate proportions, burning them until they are partially or completely melted, and cooling them. In the cement industry, the most commonly used cement clinker has calcium oxide, silicon dioxide and a small amount of aluminum oxide and oxide. Cement powder will fly when transporting cement, so it needs to be recycled.

[0003] The Chinese authorized announcement number is CN214865137U, which is a bulk powder recovery device for cement clinker. A main recovery bin and a feed pipe are provided, and the powder in the clinker bin can be recovered into the main recovery bin and the secondary recovery bin, thereby avoiding waste and saving economic costs. The feed roller in the feed pipe facilitates the rapid transmission of the recovered powder. A striking piece and a screening net are provided. After the striking piece is struck by a first motor, the striking piece can cause the screening net to shake, thereby allowing the powder to be screened through the screening net, which is beneficial to the recovery of powders of different particles.

The powder cannot be scraped off from the surface of the conveyor belt in time, which will cause incomplete collection of the powder and waste of powder. At the same time, the position of the exhaust fan is fixed, and it can only adsorb the powder at a specific position, while the powder at a farther position cannot be collected, resulting in limited practicality of the recovery device.
