[0002] The rotary kiln is an important high-temperature processing equipment, mainly used for calcining, roasting or drying granular and powdered materials. According to the different materials processed, the rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln. The working principle of the rotary kiln is that the material gradually moves forward in the furnace as the furnace body rotates, and finally achieves the required physical and chemical properties after preheating, decomposition and calcination.

[0003] The rotary kiln is an important equipment for preparing rare earth silicon-magnesium alloy. During the production process, continuous feeding is crucial to the continuous processing and preparation of the rotary kiln. The continuous processing and preparation of the rotary kiln can ensure the continuous output of materials, facilitate the processing and production of subsequent production lines, and avoid the suspension of production lines. When the existing rotary kiln is used to prepare rare earth silicon-magnesium alloy, the uneven feeding speed or the temporary failure of the feeding equipment will affect the continuity and stability of the rotary kiln preparation, thereby affecting the preparation efficiency of the rare earth silicon-magnesium alloy; in addition, during the feeding process, the blockage of the feed pipe will also affect the continuity of the rotary kiln preparation.

[0010] In one possible implementation, a protruding shell is fixedly connected to the top of the feed pipe, and the inner cavity of the protruding shell is connected to the inner cavity of the feed pipe. The anti-stuck component includes a rotating rod rotatably installed inside the protruding shell, and a plurality of levers distributed in a spiral are fixedly installed on the rotating rod. When the lever rotates to the bottom, the bottom end is located between two adjacent spiral augers. The rotating rod is coaxially fixedly connected to the blanking plate, and the left end of the rotating rod rotates to pass through the left side of the feed pipe and is connected to the center shaft through a belt transmission.

[0011] In a possible implementation, the counter-rotating auger is fixedly mounted on the central shaft and coaxially therewith, and the counter-rotating auger is located on the left side of the first right turntable and above the discharge port.

During the feeding process, the spacing adjusting assembly can periodically adjust the spacing between adjacent spiral augers along with the rotation of the spiral auger. At the same time, the dial rod can periodically rotate between adjacent spiral augers to stir the raw materials stuck or adhered between the auger blades. Compared with the traditional spiral auger with a fixed pitch, the continuously changing spacing of the spiral auger can prevent the raw materials from getting stuck during the conveying process.

On the one hand, it avoids the occurrence of blockage caused by too much raw materials entering the inside of the feeding pipe. On the other hand, when the existing feeding equipment has uneven feeding or a short-term failure, the buffered materials can continue to supply materials to the cylinder, further ensuring the continuity and stability of the cylinder's operation.

[0017] 3. The present invention sets a reverse spiral auger to reversely convey the raw materials accumulated at the discharge port in the feeding pipe, avoiding too much raw materials accumulating at the discharge port and preventing blockage at the discharge port, ensuring the smoothness of the feeding of the feeding pipe.

Specific embodiments

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Please refer to Figures 1-3A continuous feeding and discharging rotary furnace for preparing rare earth silicon-magnesium alloy comprises a base and a cylinder 1 rotatably mounted on the base, and a feeding mechanism 2, wherein the feeding mechanism 2 comprises a feeding pipe 21 fixedly mounted on the base and located on the left side of the cylinder 1, wherein a plurality of spiral augers 22 are evenly mounted on the inner circumference of the feeding pipe 21, wherein the number of the spiral augers 22 is two, and a rotating assembly 23 for driving the plurality of spiral augers 22 to rotate and a spacing adjustment assembly 24 for periodically adjusting the spacing between two adjacent spiral augers 22 as the rotating assembly 23 rotates are mounted on the feeding pipe 21, an anti-stuck assembly 25 for shifting the raw material between two adjacent spiral augers 22 is also mounted on the feeding pipe 21, and a counter-rotating auger 26 in the opposite spiral direction to the spiral augers 22 is rotatably mounted inside the feeding pipe 21.

[0029] See also Figure 1 , Figure 2 and Figure 6 , the cache mechanism 3 includes a cache bin 31 fixedly mounted on the top of the feed port of the feed pipe 21, a material control plate 32 for controlling the falling of raw materials is rotatably mounted on the left wall of the cache bin 31, a driving motor 24 for driving the rotating component 23 is mounted on the bottom platform, and a swinging mechanism 33 for driving the material control plate 32 to swing up and down periodically is mounted on the output shaft of the driving motor 24.

[0030] See also Figures 2-4 The right end of the feed pipe 21 rotates and penetrates into the interior of the cylinder 1. A discharge port located inside the cylinder 1 is opened at the bottom of the feed pipe 21. A plurality of spiral augers 22 use shaftless augers blades. The plurality of spiral augers 22 are coaxial and located between the feed port and the discharge port. A discharge plate 35 is rotatably installed inside the discharge port.

[0031] During specific use, the raw materials are transported to the buffer bin 31 through the existing conveying equipment, and the raw materials in the buffer bin 31 fall into the feed pipe 21 from the feed port. At the same time, the driving motor 24 drives the spiral auger 22 to rotate by driving the rotating component 23, so that the spiral auger 22 transports the raw materials to the right, and the raw materials fall into the cylinder 1 from the discharge port. The driving motor 24 will also drive the swing mechanism 33 when driving the rotating component 23, so that the swing mechanism 33 drives the control plate 32 to swing back and forth up and down, and the control plate 32 is used to control the falling of the raw materials to avoid excessive falling of the raw materials inside the buffer bin 31, which will cause the feed pipe 21 to be blocked.

[0032] The raw materials are transported by cooperating with two coaxial spiral augers 22 . Compared with the conventional single augers for transporting, the distance between the two spiral augers 22 can be continuously adjusted during the rotation, which effectively prevents the raw materials from getting stuck during the transport process.

[0033] See also Figures 2-4, the rotating assembly 23 includes a central shaft 231 rotatably installed at the center of the feed pipe 21. A first turntable 232 symmetrically distributed left and right is fixedly installed on the central shaft 231. Both the feed inlet and the discharge outlet are located between the two first turntables 232 on the left and right. A pull rod 233 corresponding to the screw auger 22 is slidably installed left and right between the two first turntables 232 on the left and right. The pull rod 233 is fixedly connected to the corresponding screw auger 22 and is slidably connected to the other screw augers 22 left and right.

[0034] Please refer to Figures 2-5 , the spacing adjustment assembly 24 includes a guiding groove 241 formed on the inner annular wall of the feed pipe 21 and in an inclined elliptical ring shape. The guiding groove 241 is located on the left side of the left first turntable 232. The left end of the pull rod 233 slidably penetrates to the left side of the left first turntable 232 and is fixedly connected with a guiding rod 242. The guiding rod 242 is slidably engaged with the guiding groove 241.

[0035] Please refer to Figures 1-5 , the central shaft 231 drives the first turntable 232 to rotate, and then the first turntable 232 drives the pull rod 233 and the screw auger 22 to rotate, so that the screw auger 22 conveys the raw materials in the feed pipe 21 from left to right. During the rotation of the pull rod 233 and the screw auger 22, the pull rod 233 will drive the corresponding guiding rod 242 to rotate circumferentially. At this time, the guiding groove 241 is used to guide the guiding rod 242, so that the guiding rod 242 and the pull rod 233 move left and right reciprocally periodically, thereby driving the screw auger 22 to move left and right during rotation. Since the two screw augers 22 are circumferentially distributed, the two screw augers 22 will move synchronously and in opposite directions, so as to continuously adjust the spacing between the two screw augers 22 and prevent the raw materials from getting stuck during transportation.

[0036] Please refer to Figures 2-4 , the spacing adjustment assembly 24 further includes a stop piece 243 fixedly connected after the right end of the pull rod 233 slidably penetrates to the right side of the right first turntable 232. A second turntable 244 is fixedly connected to the central shaft 231 on the right side of the stop piece 243. A return spring 245 is fixedly connected between the right side of the stop piece 243 and the left side of the second turntable 244.

[0037] During the left and right movement of the pull rod 233, the pull rod 233 will drive the stop piece 243 to move left and right. When the stop piece 243 moves to the right, it will compress the return spring 245. The resilience of the return spring 245 is used to push the pull rod 233 to move left, which is beneficial for the screw auger 22 to move left and reset during the transportation of raw materials.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8A protruding shell 211 is fixedly connected to the top of the feed pipe 21, and the inner cavity of the protruding shell 211 is connected to the inner cavity of the feed pipe 21. The anti-stuck component 25 includes a rotating rod 251 rotatably installed inside the protruding shell 211, and a plurality of spirally distributed levers 252 are fixedly installed on the rotating rod 251. The lever 252 is an elastic telescopic rod. When the lever 252 rotates to the bottom, the bottom end is located between two adjacent spiral augers 22. The rotating rod 251 is coaxially fixedly connected to the blanking plate 35. After the left end of the rotating rod 251 rotates to the left side of the feed pipe 21, it is connected to the central shaft 231 through a belt.

[0039] During the rotation of the central shaft 231, the rotating rod 251 is driven to rotate synchronously through the belt, and then the rotating rod 251 drives the lever 252 to rotate, so that the lever 252 periodically moves the raw materials between the spiral auger 22 downward to avoid the raw materials being stuck or adhered between the auger blades, thereby ensuring the continuity of the raw material transportation; when the lever 252 rotates into the protruding shell 211, the lever 252 shrinks under the push of the protruding shell 211, and when the lever 252 rotates to the bottom, the two auger blades on both sides of the lever 252 are separated to the maximum state, and the lever 252 extends under the action of its own elastic force, which makes it convenient for the lever 252 to extend between the two auger blades, which is conducive to the loosening of the raw materials.

[0040] When the rotating rod 251 rotates, it will drive the unloading plate 35 to rotate, and the raw materials inside the cache bin 31 are transported downward to the feed pipe 21 through the unloading plate 35. The frequency of rotation of the unloading plate 35 is consistent with that of the spiral auger 22. By controlling the flipping speed of the unloading plate 35, the feed amount of the feed port can be adjusted. The unloading plate 35 is used to control the raw materials entering the feed pipe 21, which can prevent too much raw material from entering the feed pipe 21, and prevent the feed pipe 21 from being blocked due to too much raw material entering, thereby ensuring continuous feeding of the cylinder 1.

[0041] See also Figures 2-4 The reverse rotation auger 26 is fixedly mounted on the central shaft 231 and is coaxial therewith. The reverse rotation auger 26 is located on the left side of the first right turntable 232 and above the discharge port.

[0042] The raw materials are transported to the right to the discharge port and then discharged downward into the cylinder 1. When there is a lot of raw materials at the discharge port, as the raw materials accumulate more and more, the excessive raw materials will contact the reverse auger 26. The reverse auger 26 is used to transport the excessive raw materials to the left in the opposite direction to avoid the accumulation of raw materials at the discharge port and blockage. The discharge port is kept unobstructed, so that the cylinder 1 can continuously enter the raw materials, ensuring the continuity of the operation of the cylinder 1.

[0043] See also Figure 1 , Figure 2 , Figure 6 and Figure 7, an arc-shaped plate 311 is fixedly installed inside the buffer bin 31 on the right side of the material control plate 32. A feed nozzle 312 in the shape of a flared opening is fixedly connected to the top of the buffer bin 31. A through hole 321 is formed in the material control plate 32, and a flap 322 is rotatably installed inside the through hole 321. The top of the right end of the flap 322 is fixedly connected with limiting rods 323 symmetrically distributed front and back. The top ends of the limiting rods 323 slide through above the material control plate 32 and are fixedly connected with a stop block.

[0044] By arranging the buffer bin 31 to buffer the raw materials, the material control plate 32 can swing up and down periodically as the spiral auger 22 rotates, controlling the feeding amount of the raw materials. On the one hand, it avoids the situation that too much raw materials enter the inside of the feed pipe 21 and cause blockage. On the other hand, when the existing feeding equipment has uneven feeding or a short-term failure, the buffered materials can continue to supply materials to the cylinder 1, further ensuring the continuity and stability of the operation of the cylinder 1.

[0045] When the material control plate 32 moves upward, the flap 322 rotates downward and opens under the extrusion of the raw materials above the material control plate 32, so that the raw materials fall through the through hole 321 to the lower part of the material control plate 32. When the material control plate 32 moves downward, the flap 322 rotates reversely under the extrusion of the raw materials below the material control plate 32 and closes the through hole 321, so that the flap 322 and the material control plate 32 rotate downward together and extrude the raw materials, avoiding the accumulation and blockage of the raw materials in the buffer bin 31 and improving the feeding efficiency of the raw materials.

[0046] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the swing mechanism 33 includes a crank 331 fixedly installed on the right side of the output shaft of the second driving motor 4. A first connecting rod 332 is rotatably installed on the crank 331. The top of the first connecting rod 332 is hinged with a second connecting rod 333. The left side of the material control plate 32 extends to the left side of the buffer bin 31 and is fixedly connected with a round rod. The top end of the second connecting rod 333 is slidably connected with the round rod left and right. The right side of the crank 331 is coaxially and fixedly connected with the left end of the central shaft 231.

[0047] The second driving motor 4 drives the crank 331 to rotate. The crank 331 drives the material control plate 32 to swing up and down reciprocally through the transmission of the first connecting rod 332 and the second connecting rod 333. During the reciprocating swing of the material control plate 32, the second connecting rod 333 will slide left and right along the round rod, and the feeding amount of the raw materials in the buffer bin 31 is controlled by the up and down swing of the material control plate 32, avoiding the situation that too much raw materials entering the feed pipe 21 cause blockage.

[0048] Please refer to Figure 1 , Figure 2 and Figure 6, further comprising a feeding assembly 34. The feeding assembly 34 includes feeding rollers 341 rotatably installed inside the buffer bin 31 and symmetrically distributed left and right. The feeding rollers 341 are located above the arc-shaped plate 311. A first driving motor 342 for driving the left feeding roller 341 to rotate is fixedly installed on the front side of the buffer bin 31. The rear side of the output shaft of the first driving motor 342 is coaxially and fixedly connected to the left feeding roller 341. A transmission gear 343 located at the rear side of the buffer bin 31 is coaxially and fixedly connected to the rear side of the feeding roller 341. The two transmission gears 343 on the left and right are engaged with each other.

[0049] The first driving motor 342 drives the left feeding roller 341 to rotate. The left feeding roller 341 drives the right feeding roller 341 to rotate in the opposite direction through the transmission of the two transmission gears 343. The raw materials entering the feeding nozzle 312 are conveyed downward through the mutual cooperation of the two feeding rollers 341. The feeding rollers 341 can further crush the raw materials to avoid the situation of jamming due to the excessive size of the raw materials.

For example, it can be a fixed connection, a detachable connection, an integral connection, or a sliding connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
