[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6This utility model provides a technical solution: a raw material batching device for improving clinker strength, comprising a batching box 1, a feeding pipe 2, and a mixing mechanism 4. The feeding pipe 2 is connected to both sides of the top of the batching box 1, and the discharge pipe 3 is connected to both sides of the bottom of the batching box 1. The mixing mechanism 4 includes a frame 401, a servo motor 402, a transmission rod 403, a fixed bevel gear 404, a rotating column 405, a first bevel gear 406, a transmission column 407, a flow divider 408, a mixing seat 409, a transmission bevel gear 410, a stirring seat 411, a protective box 412, a second bevel gear 413, a support column 414, and a mixing rod 415. A frame 401 is connected to the top center of the mixing box 1, and a servo motor 402 is installed at the top center of the frame 401. A transmission rod 403 is connected to the output end of the servo motor 402. A fixed bevel gear 404 is connected to the bottom of the outer wall of the transmission rod 403, and a rotating column 405 is welded to the bottom center of the fixed bevel gear 404. A mixing seat 409 is sleeved on the top of the outer wall of the rotating column 405, and a transmission bevel gear 410 is welded to the middle of the outer wall of the rotating column 405. A stirring seat 411 is connected to the bottom of the outer wall of the rotating column 405. The mixing seat 409 has a cross-shaped structure and is evenly spaced. The stirring seat 41... The outer contour is conical. A movable cavity is provided inside the frame 401. The bottom end of the rotating column 405 is connected to the inner wall of the mixing box 1 via a bearing seat. A second bevel gear 413 is meshed on both sides of the bottom end of the transmission bevel gear 410. A protective box 412 is provided on the outer side of the second bevel gear 413, and the outer wall of the protective box 412 is connected to the mixing box 1 via a support plate. The second bevel gear 413 is distributed at equal angles. A support column 414 is welded inside the second bevel gear 413, and a mixing rod 415 is sleeved in the middle of the outer wall of the support column 414. The mixing rod 415 is triangularly distributed, and the support column 414 is far from the second bevel gear 410. One side of the fixed bevel gear 404 is connected to the protective box 412 via a bearing seat; the two sides of the outer wall of the fixed bevel gear 404 are meshed with a first bevel gear 406, and a transmission column 407 is welded inside the first bevel gear 406. A flow divider 408 is connected to the outer wall of the transmission column 407 away from the first bevel gear 406; the flow divider 408 has a cross-shaped structure and is symmetrically distributed about the vertical center line of the frame 401; the flow divider 408 is located inside the discharge pipe 3, the fixed bevel gear 404 and the first bevel gear 406 are perpendicular to each other, and the transmission bevel gear 410 and the second bevel gear 413 are perpendicular to each other.

[0022] In practical implementation, during the use of this raw material batching device that can improve clinker strength, in order to improve mixing efficiency, the servo motor 402 on the top of the frame 401 is first started. Since the output end of the servo motor 402 is connected to the transmission rod 403, the start of the servo motor 402 will drive the transmission rod 403 to rotate. Furthermore, since the bottom end of the transmission rod 403 is connected to the fixed bevel gear 404, and the bottom end of the fixed bevel gear 404 is connected to the rotating column 405, the rotation of the transmission rod 403 will drive the fixed bevel gear 404 to rotate. 4. When the fixed bevel gear 404 rotates, it will drive the rotating column 405 to rotate. Since the rotating column 405 is connected to the mixing seat 409, the transmission bevel gear 410 and the stirring seat 411, the rotation of the rotating column 405 will drive the mixing seat 409, the transmission bevel gear 410 and the stirring seat 411 to rotate together. At this time, the rotation of the mixing seat 409 forms a vertical stirring vortex at the top of the inner wall of the mixing box 1, and the stirring seat 411 forms a vertical stirring vortex at the bottom of the inner wall of the mixing box 1.

[0023] Because the transmission bevel gear 410 and the second bevel gear 413 are meshed, the rotation of the transmission bevel gear 410 will drive the second bevel gear 413 to rotate together. At this time, the transmission bevel gear 410 and the second bevel gear 413 are protected by the protective box 412. Then, the rotation of the second bevel gear 413 will drive the support column 414 to rotate together. Since the support column 414 is connected to the mixing rod 415, the rotation of the support column 414 will drive the mixing rod 415 to rotate together, thereby forming three sets of transverse stirring in the middle of the inner wall of the batching box 1. The mixing vortex, through the cooperation of two sets of vertical mixing vortices and three sets of horizontal mixing vortices, mixes the raw cement meal, so that the material in the batching box 1 can be subjected to multi-directional mixing force. Compared with single-directional mixing, this multi-directional mixing method can break up the agglomeration between materials more quickly, so that the material particles are more evenly dispersed in the batching box 1, and can also enhance the turbulence effect during the mixing process, further improving the uniformity and efficiency of mixing, thereby shortening the mixing cycle and improving the mixing efficiency.

[0024] Because the fixed bevel gear 404 and the first bevel gear 406 are meshed, the rotation of the fixed bevel gear 404 will drive the first bevel gear 406 to rotate together. Then, the rotation of the first bevel gear 406 will drive the transmission column 407 to rotate. Since the transmission column 407 is connected to the diverter seat 408, the rotation of the transmission column 407 will drive the diverter seat 408 to rotate together. As the diverter seat 408 rotates, it will divide the inside of the feed pipe 2 into four small spaces, so that only the material in a single space enters the batching box 1 per unit time. This will relieve the feeding pressure and prevent the feed pipe 2 from being blocked due to excessive feeding pressure. Therefore, when using the raw material batching device to improve the strength of clinker, it will help to relieve the feeding pressure and improve the mixing efficiency.

[0025] In summary, when using this raw material batching device for improving clinker strength, the raw materials are first introduced into the batching box 1 through the feed pipe 2. Then, the introduced raw materials are fully mixed by the rotation of the mixing components. Barium slag is used for batching, and the clinker strength is improved by using a stable flame temperature. After that, the raw materials are discharged from the batching box 1 through the discharge pipe 3 to enter the next process. This is prior art and will not be elaborated on here. The mixing mechanism 4 allows the material to be subjected to multi-directional stirring forces in the batching box 1, making the material more evenly dispersed in the device. It can also enhance the turbulence effect during the stirring process, thereby improving the uniformity and efficiency of mixing and shortening the mixing cycle. Furthermore, the feed pipe 2 is divided into four small spaces, so that only the material in a single space enters the batching box 1 per unit time, thereby relieving the feeding pressure and preventing the feed pipe 2 from being blocked due to excessive feeding pressure. The contents not described in detail in this description are prior art known to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
