Description

Technical Field

[0001] This application relates to the field of cement production equipment technology, and more specifically, to a cement batching device. Background Technology

[0002] The cement production process generates a large amount of industrial waste residue, such as fly ash, slag, desulfurization gypsum, etc. After some of the industrial waste residue is mixed and ground, it can be used as cement raw material and mixed with clinker in a certain proportion through a cement batching device to form cement. This can alleviate the problem of resource shortage and reduce the cost of cement production.

[0003] However, existing cement batching equipment generally lacks a dedicated material premixing structure. After the raw materials are metered, they are mostly directly fed into the subsequent mixing stage in a discrete state, making it difficult to quickly achieve uniform dispersion between components. This forces the subsequent mixing stage to extend the operation time to eliminate this initial uneven distribution, resulting in an increase in the processing cycle of each batch of materials and a reduction in overall production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a cement batching device that can solve the technical problems raised in the background art.

[0005] This application provides a cement batching device, including a housing. The housing is divided into a premixing chamber and a mixing chamber from top to bottom. A premixing mixing assembly is rotatably arranged in the premixing chamber, and a mixing mixing assembly is rotatably arranged in the mixing chamber. A premixing drive motor for driving the premixing mixing assembly to rotate and a mixing drive motor for driving the mixing mixing assembly to rotate are fixed on the housing. At least two batching feed assemblies communicating with the premixing chamber are provided on the top of the housing.

[0006] Furthermore, the bottom of the premixing chamber is conical, and the bottom of the premixing chamber is provided with a discharge port that communicates with the mixing chamber, and a discharge valve is provided at the discharge port.

[0007] Furthermore, the premixing assembly includes a premixing shaft and a plurality of premixing rods. The premixing shaft is rotatably disposed in the premixing chamber. The upper end of the premixing shaft extends to the outside of the housing and is connected to the output shaft of the premixing drive motor. The plurality of premixing rods are fixedly disposed on the premixing shaft at equal intervals along the axial direction of the premixing shaft. A first scraper is fixedly connected to the end of each premixing rod away from the premixing shaft. The first scraper abuts against the inner wall of the premixing chamber.

[0008] Furthermore, the mixing assembly includes a mixing shaft and a plurality of mixing rods. The mixing shaft is rotatably disposed in the mixing chamber. The upper end of the mixing shaft extends to the outside of the housing and is connected to the output shaft of the mixing drive motor. The plurality of mixing rods are fixedly fixed at equal intervals on the mixing shaft along the axial direction of the mixing shaft. A second scraper is fixedly connected to one end of each mixing rod away from the mixing shaft. The second scraper abuts against the inner wall of the mixing chamber.

[0009] Furthermore, the ingredient feeding assembly includes an ingredient hopper, a mounting frame, a weighing sensor, and an ingredient valve. The mounting frame is fixed to the top of the housing, the ingredient hopper is movably mounted on the mounting frame, the weighing sensor is fixed to the mounting frame and abuts against the bottom of the ingredient hopper, the bottom of the ingredient hopper is connected to an ingredient pipe, the lower end of the ingredient pipe extends movably into the premixing chamber, and the ingredient valve is mounted on the ingredient pipe and located outside the housing.

[0025] like Figure 1 and Figure 2 As shown, this application provides a cement batching device, including a housing 1. The housing 1 is divided into a premixing chamber 11 and a mixing chamber 12 from top to bottom. A premixing mixing assembly 2 is rotatably arranged in the premixing chamber 11, and a mixing mixing assembly 3 is rotatably arranged in the mixing chamber 12. A premixing drive motor 4 for driving the premixing mixing assembly 2 and a mixing drive motor 5 for driving the mixing mixing assembly 3 are fixed on the housing 1. At least two batching feed assemblies 6 communicating with the premixing chamber 11 are provided on the top of the housing 1. When the cement batching device is working, each raw material enters the premixing chamber 11 through the batching feed assemblies 6 on the top of the housing 1. The premixing drive motor 4 drives the premixing mixing assembly 2 to rotate, and performs preliminary mixing of the raw materials entering the premixing chamber 11. After premixing, the material enters the mixing chamber 12 connected below. The mixing drive motor 5 drives the mixing agitator 3 to rotate, further mixing the material. Through the two-stage treatment of premixing and mixing, the cement raw materials are fully mixed. This cement batching device, by setting up independent premixing chamber 11 and mixing chamber 12, and equipped with premixing agitator 2 and mixing agitator 3 respectively, realizes the graded mixing of raw materials, effectively improving the problem of uneven mixing of raw materials caused by the lack of premixing structure in traditional batching devices. In the continuous cement production process, when the mixing chamber 12 is operating, the premixing chamber 11 can premix the next batch of materials. The synergistic effect of the premixing agitator 2 and mixing agitator 3 shortens the overall mixing time and improves the mixing efficiency.

[0026] like Figure 2 As shown, the bottom of the premixing chamber 11 is conical, and the bottom of the premixing chamber 11 is provided with a discharge port 13 that communicates with the mixing chamber 12. The discharge port 13 has a discharge valve 131. The conical structure of the bottom of the premixing chamber 11 facilitates the falling of materials, and the discharge valve 131 can control the materials to enter the mixing chamber 12 from the premixing chamber 11.

[0027] like Figure 2As shown, the premixing assembly 2 includes a premixing shaft 21 and multiple premixing rods 22. The premixing shaft 21 is rotatably mounted inside the premixing chamber 11. The upper end of the premixing shaft 21 extends outside the housing 1 and is connected to the output shaft of the premixing drive motor 4. The multiple premixing rods 22 are fixedly mounted on the premixing shaft 21 at equal intervals along the axial direction of the premixing shaft 21. A first scraper 7 is fixedly connected to the end of each premixing rod 22 away from the premixing shaft 21. The first scraper 7 is connected to the inner surface of the premixing chamber 11. The premixing shaft 21 is connected to the housing 1 with a bearing. The premixing drive motor 4 drives the premixing shaft 21 to rotate, so that multiple premixing stirring rods 22 fixed on the shaft rotate synchronously with the shaft to stir and mix the raw materials entering the premixing chamber 11. At the same time, the first scraper 7 at the end of the premixing stirring rod 22 rotates with the premixing stirring rod 22 to scrape off the material adhering to the inner wall of the premixing chamber 11, improve the mixing effect, and avoid material residue when discharging.

[0028] like Figure 2 As shown, the mixing assembly 3 includes a mixing shaft 31 and multiple mixing rods 32. The mixing shaft 31 is rotatably mounted inside the mixing chamber 12. The upper end of the mixing shaft 31 extends outside the housing 1 and is connected to the output shaft of the mixing drive motor 5. The multiple mixing rods 32 are fixedly mounted on the mixing shaft 31 at equal intervals along the axial direction of the mixing shaft 31. A second scraper 8 is fixedly connected to the end of the mixing rod 32 away from the mixing shaft 31. The second scraper 8 abuts against the inner wall of the mixing chamber 12. Specifically, a bearing is provided at the connection between the mixing shaft 31 and the housing 1. The mixing shaft 31 is driven by the mixing drive motor 5 to rotate the mixing rods 32, thereby mixing the raw materials entering the mixing chamber 12 and ensuring that the cement raw materials are fully mixed. The second scraper 8 rotates with the mixing rods 32 and scrapes off the material adhering to the inner wall of the mixing chamber 12.

[0029] like Figure 2As shown, the batching and feeding assembly 6 includes a batching bin 61, a mounting frame 62, a weighing sensor 63, and a batching valve 64. The mounting frame 62 is fixed to the top of the housing 1. The batching bin 61 is movably mounted on the mounting frame 62. The weighing sensor 63 is fixed to the mounting frame 62 and abuts against the bottom of the batching bin 61. A batching pipe 611 is connected to the bottom of the batching bin 61. The lower end of the batching pipe 611 extends movably into the premixing chamber 11. The batching valve 64 is mounted on the batching pipe 611 and located outside the housing 1. Specifically, there are two batching and feeding assemblies 6, which are symmetrically arranged and used for weighing and batching clinker and waste residue mixtures, respectively. The batching bin 61 is placed on the mounting frame 62, and the weighing sensor 63 is a ring. The feed pipe 611 passes through the middle of the weighing sensor 63. The weighing sensor 63 is connected to an external controller. The feed valve 64, the discharge valve 131, and the discharge valve 141 are all electric valves. The controller is electrically connected to the feed valve 64, the discharge valve 131, the discharge valve 141, the premix drive motor 4, and the mixing drive motor 5, respectively, to form an automated control system. When it is necessary to feed material into the premix chamber 11, the feed valve 64 is opened, and the raw material falls into the premix chamber 11 along the feed pipe 611 (a movable gap is reserved at the penetration point between the feed pipe 611 and the housing 1 to accommodate the slight displacement of the feed bin 61). The weighing sensor 63 provides real-time feedback on the weight change of the feed bin 61, which facilitates the control of the amount of material fed in a single batch. After the feeding is completed, the feed valve 64 is closed to stop the feeding.

[0030] like Figure 2 As shown, a sealing ring 9 is provided at the connection between the dispensing pipe 611 and the housing 1. The sealing ring 9 can prevent dust leakage caused by gaps at the connection between the dispensing pipe 611 and the housing 1, thus avoiding dust pollution of the production environment and harm to the health of operators.

[0031] like Figure 2 As shown, the bottom of the shell 1 is provided with a discharge port 14 that communicates with the mixing chamber 12, and a discharge valve 141 is provided at the discharge port 14. When the material in the mixing chamber 12 is fully mixed, the discharge valve 141 at the discharge port 14 is opened, and the mixed material is discharged from the shell 1 through the discharge port 14 under the action of gravity and enters the subsequent production process.

[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
