[0002] Cement is an important building material, mainly used in the production of concrete and mortar. It is a powdery substance made by high-temperature calcination and grinding of raw materials such as limestone, clay, iron ore and gypsum. The main component of cement is silicate minerals. Common types of cement include ordinary Portland cement, slag cement and high-definition cement. The rotary kiln is one of the important equipment in the cement production process, mainly used to calcine raw materials to produce clinker.

When the material in the rotary cylinder passes through, the stirring device separates the material and then mixes it. The material does not all gather together, which is conducive to more uniform mixing of the material and ensures the quality of the produced cement clinker.

[0004] Although the above-mentioned device can separate and mix materials through the stirring device, its stirring device is a semicircular ring arranged relatively vertically. Due to its relatively vertical arrangement, it is easy to block the materials being transported and easily cause some materials to accumulate on the rear side of the stirring device. Moreover, due to its relatively vertical arrangement, its effect of stirring and separating the materials is not particularly good and is not practical enough. Therefore, a rotary kiln for cement production is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3The present invention provides an embodiment of a rotary kiln for cement production, comprising a bottom plate 1 for cooperating with the connection between various components, a feed bin 2 for feeding is provided on the left side of the top surface of the bottom plate 1, and a material guide slope 21 is provided on the lower part of the inner wall of the feed bin 2, which is higher on the left and lower on the right, for assisting the material to enter the kiln body 4, and a dispersion component 3 is provided in the middle of the feed bin 2 for dispersing the material to prevent the material from agglomerating and sticking, so that the device can better calcine the material, and a discharge bin 5 is provided on the right side of the top surface of the bottom plate 1 for sending the clinker out of the device, which is connected to the kiln body 4, and a kiln body 4 is provided between the feed bin 2 and the discharge bin 5 for calcining the material, and the inner wall of the kiln body 4 is fixedly connected with a stirring piece 41 in plurality, which is made of refractory material and is spirally attached to the inner wall of the kiln body 4, which can turn over the internal material when the kiln body 4 rotates, thereby assisting the mixing and calcination of the material.

[0032] like Figure 4 As shown, the dispersion component 3 includes a motor 31 for providing power for the component. The motor 31 is fixedly connected to the left side of the feed bin 2. The output end of the motor 31 is fixedly connected to a rotating shaft 32. The rotating shaft 32 passes through the feed bin 2 and is rotatably connected thereto, and is used to cooperate with the connection to the mounting rod 33. The right end of the rotating shaft 32 is fixedly connected to the mounting rod 33 for coordinating the connection between the various components. An auxiliary rod 35 is provided on the right part of the mounting rod 33, which is provided in the mounting cavity 331. The auxiliary rod 35 is fixedly connected to the inner wall of the feed bin 2. Dispersing parts 34 are provided on the upper and lower sides of the mounting rod 33 for dispersing materials.

[0033] Furthermore, an installation cavity 331 is provided on the right side of the installation rod 33, which is used to provide installation space for components. The dispersion part 34 includes a connecting rod 341, which is used to cooperate with the connecting dispersion piece 342. The outer wall of the connecting rod 341 is fixedly connected with a plurality of dispersion pieces 342, which are staggered and used to disperse the materials. The lower part of the connecting rod 341 is fixedly connected with a rotating rod 343, which is used to cooperate with the connection between the No. 1 bevel gear 344 and the connecting rod 341. The rotating rod 343 passes through the installation rod 33 and is rotatably connected thereto. The side of the rotating rod 343 close to the auxiliary rod 35 is fixedly connected with the No. 1 bevel gear 344, which is used to cooperate with the No. 2 bevel gear 351. The left end of the auxiliary rod 35 is fixedly connected with the No. 2 bevel gear 351, which is used to cooperate with the No. 1 bevel gear 344 to rotate, and the No. 1 bevel gear 344 is meshed with it.

[0034] Working principle: When in use, pour the material into the device through the top of the feed bin 2, and turn on the motor 31 at the same time, which will drive the rotating shaft 32 connected to it to rotate, and the installation rod 33 connected to the rotating shaft 32 will be driven to rotate accordingly. When the installation rod 33 rotates, the dispersion member 34 connected to it through the rotating rod 343 will be driven to rotate accordingly. At this time, the two No. 1 bevel gears 344 will rotate around the No. 2 bevel gear 351. Since the position of the No. 2 bevel gear 351 is fixed and the No. 1 bevel gear 344 is engaged with it, when the No. 1 bevel gear 344 rotates around it, the No. 1 bevel gear 344 will also rotate. When the gear 344 rotates, the rotating rod 343 connected to it will rotate together, and the connecting rod 341 connected to it will also rotate accordingly, and drive the dispersion piece 342 to rotate, so as to disperse the fallen material and prevent the material from clumping and sticking. The dispersed material will fall on the guide slope 21 and be sent to the kiln body 4 through the guide slope 21. The material will be calcined in the kiln body 4. At the same time, due to the rotation of the kiln body 4 and the stirring piece 41 provided inside it, the stirring piece 41 will stir and mix the material. At the same time, due to its spiral shape, when the kiln body 4 rotates, it will move the auxiliary material toward the discharge bin 5, and the calcined clinker will be discharged through the discharge bin 5.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
