Description

Technical Field

[0001] The invention relates to the technical field of rotary kilns, in particular to a rotary kiln for processing rare earth materials based on temperature field regulation. Background Art

[0002] The rotary kiln mainly involves the tumbling and movement of rare earth materials in the kiln, while the heat generated by fuel combustion is transferred to the rare earth materials to complete the chemical reaction and phase change process. Specifically, when the material enters the kiln, due to the tilting and slow rotation of the cylinder, the material tumbles in the circumferential direction and moves in the axial direction (from the high end to the low end), and a liquid phase is generated during the movement, generating various minerals, and unloaded from the kiln head after sintering. The traditional structure of the rotary kiln is equipped with a flue at the kiln head, but due to the very high gas temperature in the rotary kiln, it is easy to cause the kiln head to deform, and the flue is set at the kiln head, which makes the material not fully melted, reducing the output of the rotary kiln and reducing the conversion of rare earths in the material.

[0003] The Chinese patent publication number is CN 202119239 U, which discloses a rotary kiln for the processing and production of rare earth materials. A flue is arranged at the kiln tail hood, which is conducive to the full melting of the material in the rotary kiln. A dust removal device is connected to the flue to prevent the flue from polluting the environment. In order to prevent the high-temperature flue gas entering the flue from deforming the flue, the kiln tail hood is provided with a cooling water interlayer to cool the exhausted flue gas; a fan is installed at the downstream position of the dust removal device, which can accelerate the discharge of gas in the rotary kiln, is more conducive to the full melting of the material in the rotary kiln, and improves the output and conversion rate.

[0004] However, in the actual application of this device, when the operator adds different amounts of materials into the equipment, it is difficult for the system to automatically and accurately adjust the amount of fuel entering the kiln body. If the fuel supply is insufficient, the added materials cannot be fully burned, which not only reduces production efficiency, but may also produce incomplete combustion products and have a negative impact on the environment. Secondly, if the fuel is excessive, in addition to causing unnecessary energy waste, excessive heat may also damage the quality of the material itself, such as causing problems such as excessive sintering, which in turn affects the quality of the final product.

When the rotating rod 308 rotates, the rotating rod 308 has an upward elastic force, ensuring that the rotating rod 308 is not easy to move, thereby ensuring the stability of the valve ball 306, thereby improving the stability of the fuel passing through the valve body 305.

[0035] The control mechanism 4 is arranged on one side of the valve body 305. The control mechanism 4 includes a fixed sleeve 410 fixedly installed on the top surface of the rotating rod 308.

Two pressing plates 405 are fixedly installed on one end of the multiple push rods 404.

[0037] In this embodiment: by pressing the pressing plate 405 , the push rod 404 is driven to move, and the push rod 404 drives the push plate 403 to move.

[0038] Specifically, Figure 1-Figure 8 As shown, a cavity 406 is opened inside one end of the connecting rod 309, and two limit plates 407 are slidably installed on the inner wall of the cavity 406. The two limit plates 407 are fixedly installed with elastic members 408 close to the sides, and the two limit plates 407 are fixedly installed with wedge plates 409 away from the sides. One ends of the two wedge plates 409 slide through the inner wall of the cavity 406 and extend to the outside of the connecting rod 309.
