Technical Field

[0001] The invention belongs to the technical field of filling devices, and in particular relates to an energy-saving cement quantitative filling device for a cement grinding station and a use method thereof. Background Art

[0002] Cement grinding station is a cement finished product production unit formed by separating the final finished product stage in cement production. In this stage, cement clinker is added with appropriate amount of mixed materials and gypsum for grinding to produce finished cement. Cement production can generally be divided into three processes: raw material preparation, clinker calcination and cement production. After the cement finished product is produced, it is transported to the filling device by a belt conveyor for filling, and then the cement powder is placed in cement bags for quantitative filling.

[0003] At present, when people fill cement, the cement bags are usually open. After the cement falls into the bag, it will impact with the cement belt, causing a large amount of cement to float into the air. This will cause a waste of cement, aggravate the consumption of resources, is not energy-saving, and is difficult to clean, time-consuming and labor-intensive. At the same time, after the cement is inhaled into the human body, it will affect the health of the body, and the filling cost is high.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an energy-saving cement quantitative filling device for cement grinding station and a method for using the same. Summary of the invention
