Abstract

The present invention relates to the technical field of rotary kilns, and specifically relates to a rotary kiln for processing rare earth materials based on temperature field regulation, mainly including a kiln body and a shock absorption mechanism. The shock absorption mechanism is arranged below the kiln body and includes a support plate located below the kiln body. An adjustment mechanism is arranged on the left side of the support plate, and the adjustment mechanism includes a valve body located on the left side of the support plate. A control mechanism is arranged on one side of the valve body. When the weight of the rare earth materials added to the kiln body increases, due to the pressure of the support blocks and the shock absorption plate on the first elastic member, the shock absorption plate moves a certain distance, and the shock absorption plate drives the L-shaped plate, the fixed rod, and the hinge block to move. Through the connected structure, the valve ball is driven to rotate a certain angle to adjust the opening and closing size of the valve body, automatically adjusting the fuel amount entering the kiln body according to the amount of rare earth materials, which is not likely to cause too much or too little fuel amount, enabling the rare earth materials to be fully burned and not likely to cause waste of fuel, ensuring the quality of rare earth material processing.

Description

Technical Field

[0001] The present invention relates to the technical field of rotary kilns, and particularly to a rotary kiln for rare earth material processing based on temperature field regulation. Background Technique

[0002] The rotary kiln is mainly involved in the tumbling and movement of rare earth materials in the kiln. At the same time, heat generated by fuel combustion is transferred to the rare earth materials to complete the chemical reaction and phase change process. Specifically, the material enters the kiln. Due to the inclination and slow rotation of the cylinder body, the material tumbles along the circumferential direction and moves axially (from the high end to the low end). During the movement, a liquid phase is generated, various minerals are formed, and after sintering, it is discharged from the kiln head. The traditional structure of the rotary kiln is provided with a flue at the kiln head part. However, due to the very high gas temperature in the rotary kiln, it is easy to cause deformation of the kiln head part. Moreover, the flue is arranged at the kiln head part, resulting in insufficient melting and burning of the material, reducing the output of the rotary kiln and at the same time reducing the rare earth conversion in the material.

[0003] Chinese Patent Publication No. CN 202119239 U discloses a rotary kiln for rare earth material processing and production. A flue is arranged at the kiln tail cover, which is beneficial to the full melting and burning of the material in the rotary kiln. A dust removal device is connected to the flue to prevent the flue gas from polluting the environment. In order to prevent the high-temperature flue gas entering the flue from deforming the flue, the kiln tail cover is provided with a cooling water interlayer to cool the discharged flue gas; a fan is installed at the downstream position of the dust removal device to accelerate the discharge of the gas in the rotary kiln, which is more conducive to the full melting and burning of the material in the rotary kiln, improving the output and conversion rate.

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

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the present invention, the weight increases after the rare earth material is added to the kiln body. Due to the pressure of the support block and the shock-absorbing plate on the elastic member I, the shock-absorbing plate moves a certain distance. The shock-absorbing plate drives the L-shaped plate, the fixed rod and the hinge block to move. The hinge block drives the hinge rod to move. The hinge rod drives the connecting rod, the rotating rod and the adjusting rod to rotate a certain angle. Moreover, the rotating rod squeezes the elastic member II. The adjusting rod drives the valve ball to rotate a certain angle, thereby adjusting the opening and closing size of the valve body. Furthermore, the fuel quantity entering the kiln body from the valve body can be automatically adjusted according to the amount of the rare earth material, which is not likely to cause the situation of too much or too little fuel quantity, enabling the rare earth material to be fully burned and not likely to cause waste of fuel, and ensuring the quality of rare earth material processing;

[0022] By adding the rare earth material into the kiln body, the kiln body drives the lower support frame and the support block to move under force, driving the shock-absorbing plate to move. The shock-absorbing plate squeezes and contracts the elastic member I and the telescopic damper, thereby cushioning and damping the kiln body, making the kiln body not likely to be damaged and improving the service life of the kiln body;

[0023] By pressing the pressing plate, the push rod and the push plate are driven to move to squeeze the wedge plate. The movement of the wedge plate pushes the limit plate to squeeze the third elastic member. When one end of the wedge plate moves into the cavity, the connecting rod can be removed. Manually rotate the rotating rod and drive the fixed sleeve to rotate to a certain position, and fix the fixed sleeve at the threaded hole through the bolt. At the same time, when the rotating rod rotates, it drives the adjusting rod and the valve ball to rotate, so that the fuel amount passing through the valve body can be manually controlled, thereby improving the flexibility and practicability of the device and being easy to actively control.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application

[0039] As Figures 1-8 shown, the present application provides a rotary kiln for rare earth material processing based on temperature field regulation, including a kiln body 1. The two ends of the kiln body 1 are respectively rotatably installed with a kiln head cover 101 and a kiln tail cover 103. The bottom surfaces of the kiln head cover 101 and the kiln tail cover 103 are fixedly installed with support frames 105. A discharge port 104 is provided through the bottom surface of the kiln tail cover 103

[0040] Specifically, as Figures 1-8 shown, a feed hopper 102 is fixedly installed on the top surface of the kiln head cover 101. Support assemblies 106 and power assemblies 107 are fixedly installed on the top surfaces of the support frames 105. The support assemblies 106 are used to support the kiln body 1, and the power assemblies 107 are used to drive the kiln body 1 to rotate. An installation frame 108 is arranged on the left side of the kiln body 1, and a fan 109 is fixedly installed on the side surface of the installation frame 108

[0041] In this embodiment: By arranging the fan 109, continuous air intake is carried out inside the kiln body 1, so that fuel can continuously enter the kiln body 1 to process rare earth fuel

[0042] Specifically, as Figures 1-8As shown, a connecting pipe 110 is fixedly installed at the air outlet end of the fan 109, and the other end of the connecting pipe 110 is fixedly connected to a connecting pipe 2 112 through a hose 113. A burner 111 is arranged inside the connecting pipe 2 112, and one end of the connecting pipe 2 112 is fixedly passed through the side of the kiln tail cover 103 and extends to the inside of the kiln body 1.

[0043] In this embodiment, the fuel is burned by the burner 111, and the hose 113 is arranged so that the position of the fan 109 is not easily affected when the kiln body 1 moves up and down.

[0044] A shock absorbing mechanism 2 is arranged below the kiln body 1. The shock absorbing mechanism 2 comprises a support plate 201 located below the kiln body 1. A plurality of elastic members 205 are arranged inside the support plate 201. The shock absorbing mechanism 2 is used to reduce the vibration of the kiln body 1.

[0045] Specifically, Figures 1-8 As shown, a shock absorbing cavity 202 is opened inside the support plate 201, a shock absorbing plate 204 is slidably installed on the inner wall of the shock absorbing cavity 202, a plurality of telescopic dampers 203 are fixedly installed on the bottom surface of the shock absorbing plate 204, and the lower ends of the plurality of telescopic dampers 203 are fixedly connected to the inner wall of the lower end of the shock absorbing cavity 202.

[0046] In this embodiment, a plurality of telescopic dampers 203 are provided to ensure that the shock absorbing plate 204 has a certain damping when moving, so that the shock absorbing plate 204 moves more smoothly.

[0047] Specifically, Figures 1-8 As shown, multiple elastic members 205 are movably sleeved on the outer wall of the telescopic damper 203, and the two ends of the multiple elastic members 205 are respectively fixedly connected to the bottom surface of the shock-absorbing plate 204 and the inner wall of the lower end of the shock-absorbing cavity 202, and multiple support blocks 206 are fixedly installed on the top surface of the shock-absorbing plate 204. The upper ends of the multiple support blocks 206 slide through the inner wall of the upper end of the shock-absorbing cavity 202 and are fixedly connected to the bottom surface of the support frame 105.

[0048] In this embodiment: elastic force is applied to the shock absorbing plate 204 by means of multiple elastic members 205. When rare earth material is added into the kiln body 1, the kiln body 1 moves downward. The shock absorbing plate 204 is damped and buffered by the elastic members 205, thereby the kiln body 1 is damped and buffered by the support block 206 and the support frame 105, thereby ensuring that the kiln body 1 is not prone to large shaking and increasing the service life of the kiln body 1.

[0049] The regulating mechanism 3 is arranged on the left side of the support plate 201. The regulating mechanism 3 comprises a valve body 305 located on the left side of the support plate 201. A valve ball 306 is rotatably mounted on the inner wall of the valve body 305. A rotating rod 308 is arranged on one side of the valve ball 306. The regulating mechanism 3 is used to adjust the opening and closing size of the valve body 305.

[0050] Specifically, as Figures 1-8 shown, through slots 301 are respectively formed in the front and rear sides of the support plate 201 in a penetrating manner. L-shaped plates 302 are respectively fixedly installed on the front and rear sides of the shock-absorbing plate 204. The sides of the two L-shaped plates 302 are respectively slidably connected to the inner walls of the two through slots 301. Fixing rods 303 are fixedly installed on the sides of the two L-shaped plates 302. Hinge blocks 304 are fixedly installed on the top surfaces of the fixing rods 303. Hinge rods 310 are hinged inside the hinge blocks 304. The other ends of the hinge rods 310 are hinged to connecting rods 309.

[0051] In this embodiment: By the movement of the shock-absorbing plate 204, the L-shaped plates 302 and the fixing rods 303 are driven to move. The fixing rods 303 drive the hinge blocks 304 to move. The hinge blocks 304 drive the hinge rods 310 to move. And since the sides of the two L-shaped plates 302 are respectively slidably connected to the inner walls of the two through slots 301, the through slots 301 limit the L-shaped plates 302, making the movement of the L-shaped plates 302 smoother.

[0052] Specifically, as Figures 1-8 shown, the upper end of the valve body 305 is fixedly and penetratingly installed on the bottom surface of the first connecting pipe 110. An adjusting rod 307 is fixedly installed on the outer wall of the valve ball 306. The other end of the adjusting rod 307 rotates through the inner wall of the valve body 305 and extends to the outside of the valve body 305. One end of the outer wall of the adjusting rod 307 is fixedly connected to one end of a rotating rod 308.

[0053] In this embodiment: Through the provided valve body 305 and valve ball 306, by driving the adjusting rod 307 to rotate through the rotating rod 308, the valve ball 306 is driven to rotate, so that the fuel amount passing through the valve body 305 can be adjusted.

[0054] Specifically, as Figures 1-8 shown, two support rods 311 are fixedly installed on the outer wall of the valve body 305. Elliptical plates 312 are respectively fixedly installed at the other ends of the two support rods 311. Two arc-shaped rods 313 are fixedly installed on the sides of the two elliptical plates 312. A through hole is formed in a penetrating manner on the top surface of the rotating rod 308. The outer walls of the two arc-shaped rods 313 are slidably connected to the inner wall of the through hole. Elastic members II 314 are respectively movably installed on the outer walls of the two arc-shaped rods 313. Both ends of the two elastic members II 314 are respectively fixedly connected to the side surface of the lower elliptical plate 312 and the bottom surface of the rotating rod 308.

[0055] In this embodiment: Through the arrangement of the elastic members II 314, the elastic members II 314 apply elastic forces to the rotating rod 308. When the rotating rod 308 rotates, the rotating rod 308 has an upward elastic force, ensuring that the rotating rod 308 is not prone to movement, thereby ensuring the stability of the valve ball 306, and thus improving the stability of the fuel passing through the valve body 305.

[0056] 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. An arc-shaped plate 411 is arranged on the left side of the fixed sleeve 410. A plurality of threaded holes 412 are formed in the side surface of the arc-shaped plate 411. The control mechanism 4 is used to manually control the opening and closing size of the valve body 305.

[0057] Specifically, as Figures 1-8 shown, a groove 401 is formed at one end of the rotating rod 308. Grooves 402 are respectively formed in the inner walls on both sides of the groove 401. Push plates 403 are respectively and slidably installed in the inner walls of the two grooves 402. Two push rods 404 are respectively and fixedly installed on the side surfaces of the two push plates 403. The other ends of the plurality of push rods 404 respectively slide through the inner walls of the two grooves 402 and extend to the outside of the rotating rod 308. Two pressing plates 405 are fixedly installed at one ends of the plurality of push rods 404.

[0058] 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.

[0059] Specifically, as Figures 1-8 shown, a cavity 406 is formed inside one end of the connecting rod 309. Two limiting plates 407 are slidably installed on the inner wall of the cavity 406. A third elastic member 408 is fixedly installed on the side surfaces of the two limiting plates 407 close to each other. Wedge-shaped plates 409 are respectively fixedly installed on the side surfaces of the two limiting plates 407 away from each other. One ends of the two wedge-shaped plates 409 respectively slide through the inner wall of the cavity 406 and extend to the outside of the connecting rod 309. The two wedge-shaped plates 409 are respectively clamped with the inner walls of the two grooves 402. The side surfaces of the two wedge-shaped plates 409 away from each other are respectively abutted against the side surfaces of the two push plates 403. Two mounting holes are formed through the side surface of the arc-shaped plate 411. The outer walls of the two support rods 311 are respectively fixedly connected with the inner walls of the two mounting holes.

[0060] In this embodiment: By pushing the wedge-shaped plate 409 into the cavity 406 through the push plate 403, the wedge-shaped plate 409 is removed from the groove 402, and then the connecting rod 309 can be taken out from the groove 401. By rotating the rotating rod 308 to drive the fixed sleeve 410 to rotate a certain angle, the fixed sleeve 410 is fixed to the threaded hole 412 through bolts, and then the valve ball 306 is fixed, and the fuel inlet amount can be manually adjusted, which is relatively flexible.

[0061] The specific solution of this scheme is as follows: The rare earth material is added into the kiln body 1 through the feed hopper 102. The kiln body 1 drives the supporting frame 105 and the supporting block 206 below to move under force, drives the shock-absorbing plate 204 to move. The shock-absorbing plate 204 squeezes and contracts the first elastic member 205 and the telescopic damper 203, thereby buffering the shock of the kiln body 1, making it not easy for the kiln body 1 to be damaged, improving the service life of the kiln body 1. Due to the pressure of the supporting block 206 and the shock-absorbing plate 204 on the first elastic member 205, when the shock-absorbing plate 204 moves a certain distance, the shock-absorbing plate 204 drives the L-shaped plate 302, the fixed rod 303 and the hinge block 304 to move. The hinge block 304 drives the hinge rod 310 to move, and the hinge rod 310 drives the connecting rod 309, the rotating rod 308 and the adjusting rod 307 to rotate by a certain angle. And the rotating rod 308 squeezes the second elastic member 314, and the adjusting rod 307 drives the valve ball 306 to rotate by a certain angle, thereby adjusting the opening and closing size of the valve body 305. Furthermore, the fuel amount entering the kiln body 1 from the valve body 305 can be automatically adjusted according to the amount of rare earth material, and it is not easy to cause the situation of too much or too little fuel amount, so that the rare earth material can be fully burned and the waste of fuel is not easy to occur, ensuring the quality of rare earth material processing. By pressing the pressing plate 405, it drives the push rod 404 and the push plate 403 to move and squeeze the wedge plate 409. The wedge plate 409 moves and pushes the limiting plate 407 to squeeze the third elastic member 408. When one end of the wedge plate 409 moves into the cavity 406, the connecting rod 309 can be removed. Manually rotate the rotating rod 308 and drive the fixed sleeve 410 to rotate to a certain position, and fix the fixed sleeve 410 at the threaded hole 412 through bolts. At the same time, when the rotating rod 308 rotates, it drives the adjusting rod 307 and the valve ball 306 to rotate, so that the fuel amount passing through the valve body 305 can be manually controlled, thereby improving the flexibility and practicality of the device and being easy to actively control.
