Description

Technical Field

[0001] The utility model relates to the field of cement production, and more specifically to a material adding and mixing mechanism for cement production. Background Art

[0002] Cement is a cementitious material used in construction. Cementitious materials are generally anhydrous solid substances in a metastable state in the atmospheric environment. They can dissolve, dissolve inconsistently, and react in situ in the blending liquid, releasing heat to form hydrates with small size, large specific surface area, and cementitious properties. Cementitious materials generally need to be fully ground to achieve the maximum effect in production and use. In the production process of cement, after preliminary crushing, it is ground again to grind the limestone or ore block with a diameter of 70MM to 2-5MM. The ground cement particles need to be evenly mixed with sand and iron filings in a homogenizer. The uneven addition of sand and iron filings on the existing cement production line affects the production quality of cement.

[0003] The utility model with authorization announcement number CN220219007U discloses a material adding device for a cement production line, wherein the adding component A is installed on the screed box, and the screed box is also installed with the adding component B and the adding component C, the adding component A, the adding component B and the adding component C are installed in a ring shape on the screed box, and the bottom of the screed box is also installed with a mixing component, the air intake pipe on the mixing component is connected to the air supply pipe, and the air supply pipe is connected to the fan. By arranging the adding components A, the adding components B and the adding components C in a ring shape and with suitable structures at intervals on the screed box, after the servo motor A on the adding component A is started, the spiral structure feeding plate connected to the rotating shaft A is driven to rotate in the feeding pipe B, so that sand and iron filings are evenly added to the crushed limestone particles in the cement production line, thereby improving the material adding quality and adding efficiency of the cement production line.

[0004] In the above-mentioned disclosed structure, materials are added directly through components and fans, and there is a lack of corresponding auxiliary structures for intermittent feeding, which easily causes material accumulation and affects the mixing effect. In addition, the feeding cannot be performed in a linked operation, and it is easy to feed materials without stirring, and it is also easy to accumulate. The adaptability is poor and needs to be improved. Utility Model Content
