[0002] A rotary kiln is a device used for high-temperature treatment and processing of materials. Its structure is similar to a large cylindrical container and can be placed horizontally or slightly tilted. This type of equipment is commonly used in various industrial processes. The rotary kiln loading device is a device used to feed raw materials or materials into the rotary kiln. These devices are usually designed to accurately feed powder, granular or liquid raw materials into the rotary kiln to ensure the continuity and efficiency of the processing process.

[0003] In the ferromolybdenum processing process, the rotary kiln feeding device plays an important role. This device covers multiple components such as a vibrating feeder, a screw feeder, a pneumatic conveying device, a belt conveyor and an automatic feeding system. These devices use their own unique technical means to ensure that the raw materials can be accurately put into the rotary kiln, thereby improving the overall production efficiency and maintaining the stability and continuity of the processing flow. However, in the design and application process of the traditional rotary kiln feeding device, the agglomeration phenomenon of some raw materials is not taken into account, which will affect the subsequent processing effect. Therefore, a feeding device for rotary kiln application is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0031] 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.

[0033] When operating the device to begin the workflow, molybdenum powder and iron powder are first poured into the feed hopper 2. Then, the motor 10 is started, causing it to drive the eccentric wheel 8 to begin rotating. The eccentric wheel 8 will further drive the crushing block 7, causing the crushing block 7 to move along a set path. Its upper end is connected to the rotating ball 6, which is mounted inside the fixed frame 5 and is restricted. When the crushing block 7 begins to rotate with the eccentric wheel 8, it will shake due to the restriction of the fixed frame 5. During the shaking process, large pieces of molybdenum powder and iron powder are stuck in the space between the crushing block 7 and the funnel 4. As the crushing block 7 continues to shake, the crushing block 7 will apply pressure to the large pieces of molybdenum powder and iron powder stuck therein, gradually breaking the large pieces of molybdenum powder and iron powder into smaller particles. This process not only improves the material processing efficiency, but also allows the molybdenum powder and iron powder to be processed more evenly, thereby improving the quality and uniformity of the final product.

[0034] Reference Figure 4-Figure 5 The side wall of the treatment cylinder 1 is fixedly connected to the first tube body 11, one end of the first tube body 11 is rotatably connected to the second tube body 12, one end of the second tube body 12 is rotatably connected to the third tube body 13, the side wall of the first tube body 11 is fixedly connected to the bracket 14, the side wall of the third tube body 13 is fixedly connected to the bracket 2 15, a connecting frame 16 is fixedly connected between the bracket 14 and the bracket 2 15, the side wall of the second tube body 12 is fixedly connected to the gear ring 17, the inside of the second tube body 12 is fixedly connected to the push plate 18, and the push plate 18 is annular The shaped array is evenly distributed inside the second tube body 12, and concave holes are opened inside the push plate 18. The inside of the bracket 2 15 is fixedly connected to the motor 2 19, and the output end of the motor 2 19 is fixedly connected to the rotating shaft 20. One end of the rotating shaft 20 is rotatably connected to the side wall of the bracket 14. The side wall of the rotating shaft 20 is fixedly connected to the gear 21, and the gear 21 is meshed with the gear ring 17. A protective cover 22 is fixedly connected between the bracket 14 and the bracket 2 15, and the protective cover 22 is sleeved on the outside of the motor 2 19, the rotating shaft 20 and the gear 21.

[0035] The crushed molybdenum powder and iron powder will be sent into a closed pipeline system formed by the first tube body 11, the second tube body 12 and the third tube body 13. During the transportation process, the motor 21 is started to drive the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 drives the gear 21 connected to it to start rotating. Because the gear 21 is engaged with the gear ring 17, the gear ring 17 will rotate with the rotation of the gear 21. The rotation of the gear ring 17 causes the second tube body 12 to rotate between the first tube body 11 and the third tube body 13, and also drives the push plate 18 located inside the second tube body 12 to reciprocate. The movement of the push plate 18 exerts a certain force on the molybdenum powder and iron powder, so that the two powders are mixed and stirred in the pipeline, ensuring that the molybdenum powder and iron powder can fully contact and mix, thereby achieving a homogenization effect.

[0036] Working principle: When using the equipment to work, first put the molybdenum powder and iron powder into the inside of the processing cylinder 1 through the feed hopper 2, and at the same time start the motor 10 to drive the eccentric wheel 8 to rotate. The rotation of the eccentric wheel 8 will further drive the crushing block 7 to move. Because the upper end of the crushing block 7 is connected to the rotating ball 6, and the rotating ball 6 is restricted in the inside of the fixed frame 5, when the crushing block 7 rotates with the eccentric wheel 8, it will shake to both sides. In the process of shaking, large pieces of molybdenum powder and iron powder will be stuck between the crushing block 7 and the funnel 4. As the shaking progresses, the crushing block 7 will The molybdenum powder and iron powder are squeezed to be crushed, and the crushed molybdenum powder and iron powder are transported through the pipeline formed by the first tube body 11, the second tube body 12 and the third tube body 13. At this time, the rotating shaft 20 is driven to rotate by starting the second motor 19, and the gear 21 is rotated. When the gear 21 rotates, it drives the gear ring 17 to rotate, and then the second tube body 12 rotates between the first tube body 11 and the third tube body 13. When the second tube body 12 rotates, it drives the push plate 18 to move, thereby stirring the molybdenum powder and iron powder to make them fully mixed.
