Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0022] like Figure 1 As shown, a system for continuously preparing cement includes a reserve parent material warehouse 1, a reserve mixed material warehouse 2, a parent material powder unit 3, a mixed material powder unit 4, a mixing unit 5, several metering bins 10, a finished product warehouse 11, a mixer 14, a first chain hook machine 15, a second chain hook machine 16, a first air conveying chute 17, a first elevator 19, a second elevator 20 and a third elevator 21. The reserve parent material warehouse 1 is connected to the parent material powder unit 3 through the first chain hook machine 15 and the first elevator 19, and the reserve mixed material warehouse 2 is connected to the mixed material powder unit 4 through the second chain hook machine 16 and the second elevator 20; the discharge port of the parent material powder unit 3 is connected in series with the feed ports of multiple metering bins 10, and the discharge port of the mixed material powder unit 4 is connected in series with the feed ports of multiple metering bins 10; the discharge ports of multiple metering bins 10 are connected to the mixing unit 5 through the first air conveying chute 17 and the third elevator 21, the mixing unit 5 is connected to the feed port of the mixer 14, and the discharge port of the mixer 14 is connected to the finished product warehouse 11.

[0023] The mixer 14 is a mechanical homogenizer that can effectively homogenize the components of cement and improve the quality and performance of cement. The first air conveying chute 17 is a pneumatic homogenizer that uses compressed air or other gases to transport cement powder to the destination, with the advantages of long conveying distance, simple operation and high degree of automation.

[0024] A continuous cement mixing system utilizes a static metering tool, a metering bin 10, to ensure macro-level material ratio accuracy. It also utilizes a pneumatic mixing device, an air conveying chute, and a mechanical mixing device, a mixer 14, to ensure micro-level mixing uniformity. This system effectively ensures accuracy and uniformity during the mixing process, thereby guaranteeing a high-quality, stable cement product.

[0025] In this embodiment, the reserve parent material warehouse 1 is provided with a number of first storage bins, and the reserve mixed material warehouse 2 is provided with a number of second storage bins. The first storage bins are used to store different cement parent materials, and the second storage bins are used to store different cement mixed materials. Different types of materials are placed in different storage bins. The materials in the first storage bin and the second storage bin are not restricted in storage mode and can be stored on shelves or in stacks, or in containers. The parent material powder unit and the mixed material powder unit are respectively provided with a number of third storage bins, and the mixing unit is provided with a fourth storage bin. The third storage bin and the fourth storage bin are both steel structure flow stabilization bins, and the materials are stored in a sealed manner in the third storage bin or the fourth storage bin.

[0026] Specifically, if Figure 1 As shown, the reserve parent material warehouse 1 has four first storage bins (#1 to #4), and the reserve mixed material warehouse 2 has four second storage bins (#5 to #8). The materials in the first storage bins fall onto the first chain hoist 15 and are transported out via the first elevator 19; the materials in the second storage bins fall onto the second chain hoist 16 and are transported out via the second elevator 20.

[0027] Four third storage bins, A, B, C, and D, are built next to the first and second elevators 19 and 20. A fourth storage bin E is also built. Third storage bins A and B serve as base material powder units 3, storing base material powder. Third storage bins C and D serve as mixed material powder units 4, storing mixed material powder. Fourth storage bin E serves as a mixing unit 5, serving as a mixing bin. Materials from the first and second storage bins are transported to the corresponding third storage bins. Each of the third storage bins A, B, C, and D is equipped with a weighing system metering bin 10 for measuring material weight. During operation, materials from third storage bins A or B and C or D are simultaneously discharged into the metering bin 10. Once both bins reach the set weight for the mix, discharge from third storage bins A or B, C or D ceases. The two metering bins 10 for the same material are interconnected. During discharge, one metering bin 10 becomes full while the other begins feeding, ensuring continuous material delivery. The metering bin 10 filled with parent material powder and mixed material powder is discharged simultaneously into the same first air conveying chute 17, and then the third elevator 21 mixes and lifts the two materials and conveys them to the fourth storage bin E. After all the materials enter the fourth storage bin E, the fourth storage bin E starts to feed the mixer 14. After the materials are evenly mixed by the mixer 14, they are sent to different finished product warehouses 11 according to different cement types.

[0028] This embodiment also includes a star-shaped feeder 12, each connected below the first, second, third, and fourth storage bins. This feeder 12 mechanically homogenizes, mixes, and conveys materials. It uses rotating spiral blades or impellers to pull or push materials out of the bin, making it suitable for unloading dust and small particles.

[0029] In this embodiment, several double-tube screw conveyors 13 are also included. The discharge port of the metering bin 10 is connected to the feed port of the double-tube screw conveyors 13. The discharge ports of the double-tube screw conveyors 13 are connected to the mixing unit 5 via a first conveying chute and a second elevator 20. The double-tube screw conveyors 13 are used to mechanically homogenize, mix, and convey the materials. The double-tube screw conveyors 13 utilize a double-helix structure, enabling continuous, uniform, and quantitative material delivery with high efficiency and stability.

[0030] In this embodiment, a second air delivery chute 18 and a fourth elevator 22 are further included, and the mixing unit 5 is connected to the finished product warehouse 11 via the second air delivery chute 18 and the fourth elevator 22. The mixing unit 5 and the finished product warehouse 11 are also directly transported by the cooperation of the transport chute and the elevator, which improves the homogenization effect while mixing.

[0032] In the present invention, unless otherwise expressly specified or limited, a first feature "on" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. "Multiple" means at least two, such as two or three, unless otherwise expressly specified or limited.
