Description

[0001] This utility model relates to the field of cement production technology, and more specifically, to a high-efficiency and energy-saving raw material pre-homogenization device for cement production. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It hardens in air or water and can firmly bind materials such as sand and stone together. In cement production, the pre-homogenization of raw materials is a key step in ensuring stable cement product quality, improving production efficiency, and achieving energy conservation and emission reduction. Raw material pre-homogenization aims to uniformly mix and process raw materials of different qualities and compositions to achieve a relatively stable chemical composition and physical properties, thereby providing a high-quality and uniform raw material base for subsequent processes such as cement clinker calcination.

[0003] Currently, existing pre-homogenization equipment has the following problems:

[0004] (1) Existing raw material pre-homogenization equipment is inconvenient to screen cement raw materials. Large particles and foreign objects mixed in the raw materials cannot be effectively removed. These impurities will wear down the equipment and affect product quality when they enter the subsequent production process.

[0005] (2) The existing technology has poor homogenization effect of cement raw materials in silos, and the homogenization time is long, resulting in high energy consumption.

[0006] Therefore, we have made improvements to this and proposed a highly efficient and energy-saving raw material pre-homogenization device for cement production. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] As shown in Figures 1, 2, 3, 4, 5, and 6, this embodiment proposes a high-efficiency and energy-saving raw material pre-homogenization device for cement production. It includes a converging frame 1, with two mounting covers 2 symmetrically and fixedly connected to the upper surface of the converging frame 1. Filter cylinders 3 are fixedly connected inside each mounting cover 2. The portion of the filter cylinder 3 inside the mounting cover 2 has evenly distributed filter holes 4. A rotating shaft 5 is rotatably connected inside the filter cylinder 3, and spiral blades 6 are fixedly connected to the rotating shaft 5. Discharge pipes 7 are fixedly connected to the sidewalls of the two mounting covers 2 near the output end of the filter cylinder 3. A homogenization tank 8 is fixedly connected to the bottom end of the converging frame 1. A stirring shaft 9 is rotatably connected inside the homogenization tank 8, and a set of stirring paddles 10 are evenly fixedly connected to the stirring shaft 9. A fixing frame 11 is provided on the lower side of the homogenization tank 8. Two support plates 12 are fixedly connected to the front and rear ends of the upper surface of the fixing frame 11. The top is fixedly connected to the collecting frame 1. The lower side of the fixed frame 11 is provided with an adjustment mechanism 13 for adjusting its tilt angle. The raw material enters the filter cylinder 3 from the feed hopper 15 through the feed port 14. The rotating shaft 5 rotates inside the filter cylinder 3, driving the spiral blades 6 to rotate and pushing the raw material forward. During the movement of the raw material, particles that meet the size of the filter holes 4 fall into the collecting frame 1 through the filter holes 4, while larger particles are pushed by the spiral blades 6 to the discharge pipe 7 for discharge. This achieves the filtration of the raw material, separating out larger impurities and improving the quality of the raw material. The collecting frame 1 collects the two raw materials at the bottom and transports them to the homogenization tank 8, thereby enabling the two raw materials to be pre-mixed at the bottom of the collecting frame 1. Then, the rotation of the stirring shaft 9 causes the stirring paddle 10 to rotate, achieving the homogenization treatment of the raw material, improving the quality stability of the raw material, and facilitating the smooth progress of subsequent cement production.

[0031] As shown in Figures 1 and 5, in a preferred embodiment, based on the above method, the adjusting mechanism 13 further includes a base frame 1301 disposed on the lower side of the fixed frame 11. Two connecting rods 1302 are symmetrically and fixedly connected to the upper right end of the base frame 1301. Connecting blocks 1303 are rotatably connected to the top ends of the two connecting rods 1302, and the top ends of the connecting blocks 1303 are respectively fixedly connected to the lower end face of the fixed frame 11. Two movable seats 1304 are symmetrically and fixedly connected to the base frame 1301. Hydraulic cylinders 1305 are rotatably connected to the two movable seats 1304. Connecting heads 1306 are fixedly connected to the driving end of the hydraulic cylinders 1305. Assembly heads 1307 are rotatably connected to the connecting heads 1306, and the top end of the assembly heads 1307 is fixedly connected to the lower end face of the fixed frame 11. By extending and retracting the hydraulic cylinders 1305, the tilt angle of the fixed frame 11 can be adjusted, thereby adjusting the tilt angle of the converging frame 1 and the homogenizing tank 8, thus facilitating the discharge of all raw materials from the homogenizing tank 8.

[0032] As shown in Figures 1 and 2, in a preferred embodiment, based on the above method, the upper left end of the filter cylinder 3 is further connected to a feed inlet 14 communicating with it, and the upper end of the feed inlet 14 is fixedly connected to a feed hopper 15; the raw material enters the feed inlet 14 through the feed hopper 15 and then enters the filter cylinder 3, which facilitates the addition of the raw material.

[0033] As shown in Figures 1 and 4, in a preferred embodiment, based on the above method, the left end of the front rotating shaft 5 passes through the filter cylinder 3 and is fixedly connected to a double-grooved pulley 16. The left end of the rear rotating shaft 5 passes through the filter cylinder 3 and is fixedly connected to a first pulley 17. The first pulley 17 is connected to the double-grooved pulley 16 via a first synchronous belt 18. A first fixed seat 19 is fixedly connected to the bottom left end of the front filter cylinder 3. A first motor 20 is fixedly connected to the first fixed seat 19. A second pulley 21 is fixedly connected to the drive end of the first motor 20. The second pulley 21 is connected to the double-grooved pulley 16 via a second synchronous belt 22. The first motor 20 drives the second pulley 21 to rotate. The second pulley 21 drives the double-grooved pulley 16 to rotate via the second synchronous belt 22. The double-grooved pulley 16 drives the first pulley 17 to rotate via the first synchronous belt 18. This enables the two rotating shafts 5 to rotate synchronously, ensuring that the raw material conveying speed in the two filter cylinders 3 is consistent, thus improving the overall working efficiency and stability of the equipment.

[0034] As shown in Figures 1 and 4, in a preferred embodiment, based on the above method, the left end of the stirring shaft 9 passes through the homogenization tank 8 and is fixedly connected to a driven pulley 23. A second fixed seat 24 is fixedly connected to the homogenization tank 8, and a second motor 25 is fixedly connected to the second fixed seat 24. The drive end of the second motor 25 is fixedly connected to a driving pulley 26. The driving pulley 26 is connected to the driven pulley 23 through a third synchronous belt 27. The second motor 25 drives the driving pulley 26 to rotate, and the driving pulley 26 drives the driven pulley 23 to rotate through the third synchronous belt 27, thereby causing the stirring shaft 9 to rotate and driving the stirring paddle 10 to stir the raw materials, thereby enabling the homogenization treatment of cement raw materials.

[0035] As shown in Figures 1 and 3, in a preferred embodiment, based on the above method, a discharge pipe 28 is fixedly connected to the right end of the homogenization tank 8, and a control valve is fixedly connected to the outer end of the discharge pipe 28; when the raw material is homogenized, the control valve is opened, and the homogenized raw material is discharged through the discharge pipe 28.

[0036] Specifically, in the use of this high-efficiency and energy-saving raw material pre-homogenization equipment in cement production: First, the first motor 20 is started to drive the second pulley 21 to rotate. The second pulley 21 drives the double-groove pulley 16 to rotate via the second synchronous belt 22. The double-groove pulley 16 drives the first pulley 17 to rotate via the first synchronous belt 18, thereby enabling the two rotating shafts 5 to rotate synchronously. The two raw materials for cement are poured into the feed hopper 15 and flow into the filter cylinder 3 through the feed inlet 14. The rotation of the rotating shaft 5 drives the spiral blades 6 to rotate, thereby pushing the raw materials forward. During the movement of the raw materials, particles that meet the size of the filter holes 4 fall into the collecting frame 1 through the filter holes 4, while larger particles are caught by the spiral blades 6. The material is pushed to the discharge pipe 7 and discharged. The gathering frame 1 gathers the two raw materials at the bottom and conveys them to the homogenization tank 8. The two raw materials can be interleaved when discharged from the outlet of the gathering frame 1 to achieve mixing. The second motor 25 is started to drive the drive pulley 26 to rotate. The drive pulley 26 drives the driven pulley 23 to rotate through the third synchronous belt 27, thereby rotating the stirring shaft 9 and driving the stirring paddle 10 to stir the raw materials, thereby homogenizing the cement raw materials. After homogenization is completed, the control valve is opened to discharge the raw materials through the discharge pipe 28. Then the hydraulic cylinder 1305 extends to adjust the tilt angle of the fixed frame 11, thereby adjusting the tilt angle of the gathering frame 1 and the homogenization tank 8, so as to facilitate the discharge of all the raw materials in the homogenization tank 8.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
