[0002] In the mining production, rotary kiln for mine is a kind of key equipment widely used in material processing. It is mainly used for preheating, calcining and a series of processing processes to ore and other materials to meet the requirements of subsequent beneficiation, smelting and other processes.

[0003] The existing rotary kiln for mine usually only relies on the rotation of rotary kiln cylinder itself to realize the movement of material in the cylinder, and this single feeding mode has certain limitations. On the one hand, its material conveying speed is relatively fixed, and it is difficult to flexibly adjust the pushing speed of material according to the characteristics of different materials and the specific requirements of different production processes. For example, for some ore with strict requirements on calcining time and temperature, fixed feeding speed may not accurately meet the process requirements, resulting in unstable product quality. On the other hand, in the long-term continuous production process, the single feeding mode is easy to make some parts of the equipment bear a large load, such as rotary driving parts, which not only increases the risk of equipment failure, but also affects the service life of the equipment, increases the operating cost and maintenance workload of the enterprise.

[0039] Please refer to Figures 1-7 A mine rotary kiln capable of pushing materials:

[0040] The mine rotary kiln mainly comprises a rotary kiln cylinder 1, a rotary driving part 2 for driving the rotary kiln cylinder 1 to rotate, pushing assemblies 4 installed at different sections inside the rotary kiln cylinder 1, and related driving parts.

[0041] The rotary kiln cylinder 1 is the main structure of the whole device, and the pushing assemblies 4 are installed at the positions of the preheating section, the transition section and the cooling section inside the rotary kiln cylinder 1. The rollers 41 in the pushing assemblies 4 are rotationally connected to the inner wall of the rotary kiln cylinder 1, and the inner wall of the rollers 41 is uniformly provided with a plurality of pushing blades 42. The pushing blades 42 can push the materials along the axial direction of the rotary kiln cylinder 1, which can not only rotate with the rotary kiln cylinder 1, but also independently push the internal ore, so as to speed up the operation of pushing the internal ore.

[0042] Three rotary pushing driving members 5 are installed on the outer wall of the rotary kiln cylinder 1 to independently drive each roller 41 to rotate. The rotary pushing driving member 5 comprises a speed reducer motor 51, a driving gear 52 and a transmission gear ring 54. The transmission gear ring 53 is installed at the middle position of the outer side wall of the roller 41, the speed reducer motor 51 is installed on the outer wall of the rotary kiln cylinder 1, the driving gear 52 is connected to the output shaft of the speed reducer motor 51, and the driving gear 52 and the transmission gear ring 54 are engaged. The rotation of the speed reducer motor 51 drives the driving gear 52 to rotate, and then drives the transmission gear ring 53 and the roller 41 to rotate, thereby realizing the rapid pushing of the materials.

[0043] The outer wall of the roller 41 is provided with a damping bearing 43 near the front and rear ends. The damping bearings 43 at both ends are installed on the inner wall of the rotary kiln cylinder 1. The damping bearing 43 can provide certain damping limiting effect when the rotary pushing driving member 5 is not used to independently accelerate the pushing of the mineral materials, thereby effectively reducing the burden of the speed reducer motor 51.

[0044] The inner wall of the roller 41 is flush with the inner wall of the rotary kiln cylinder 1, which ensures that the materials can smoothly flow along the rotary kiln cylinder 1 during the pushing process.

[0045] The rotary driving member 2 comprises a driving gear ring 22 installed at the tail end of the rotary kiln cylinder 1 and a driving base 21 distributed below the tail end of the rotary kiln cylinder 1 to drive the driving gear ring 22 to rotate. The driving base 21 drives the driving gear ring 22 to rotate, thereby rotating the rotary kiln cylinder 1 as a whole.

[0046] A rotary supporting member 3 is installed at the front end of the rotary kiln cylinder 1. The rotary supporting member 3 comprises a wheel belt 31, a support 32 and a supporting wheel 33. The support 32 is installed on the ground, the two supporting wheels 33 are installed on the top of the support 32, and the wheel belt 31 is installed on the outer wall of the rotary kiln cylinder 1. The two supporting wheels 33 are rolling supported on the bottom of the wheel belt 31, thereby providing stable support and rotation cooperation for the front end of the rotary kiln cylinder 1.

[0047] Three transmission windows 11 are formed on the outer wall of the rotary kiln cylinder 1. The driving gear 52 and the transmission gear ring 53 are engaged through the transmission windows 11. An outer cover 6 is also installed on the outer wall of the rotary kiln cylinder 1 to close the transmission windows 11 and protect the speed reducer motor 51 and the driving gear 52.

[0048] In operation, the materials enter from one end of the rotary kiln cylinder 1. Under the driving of the rotary driving member 2, the rotary kiln cylinder 1 and the pushing assembly 4 rotate synchronously. If it is necessary to accelerate the pushing speed of the internal mineral materials, the rotary pushing driving member 5 can be started again to drive the independent roller 41 in the pushing assembly 4 to rotate. The pushing blades 42 push the materials along the axial direction. After passing through different stages such as the preheating section, the transition section and the cooling section, the processing process of the materials is completed.

[0049] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
