Description

Technical Field

[0001] The invention relates to the technical field of rotary furnaces, in particular to a continuous feeding and discharging rotary furnace for preparing rare earth silicon magnesium alloy. Background Art

[0002] A rotary kiln is an important high-temperature processing equipment, primarily used for calcining, roasting, or drying granular and powdered materials. Depending on the material being processed, rotary kilns can be categorized as cement kilns, metallurgical and chemical kilns, and lime kilns. The operating principle of a rotary kiln is that the material gradually moves forward within the furnace as the furnace rotates. Through processes such as preheating, decomposition, and calcination, the material ultimately achieves the desired physical and chemical properties.

[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 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.

DETAILED DESCRIPTION

[0027] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art can make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] See also Figure 1-Figure 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 also comprises a feeding mechanism 2, the feeding mechanism 2 comprises a feeding pipe 21 fixedly mounted on the base and located on the left side of the cylinder 1, a plurality of spiral augers 22 are evenly mounted on the inner circumference of the feeding pipe 21, and the number of the spiral augers 22 is two, 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 the two adjacent spiral augers 22 is also mounted on the feeding pipe 21, and a counter-rotating auger 26 with a spiral direction opposite to that of 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, the cache mechanism 3 includes a cache silo 31 fixedly mounted on the top of the feed port of the feed pipe 21, and a material control plate 32 for controlling the falling of raw materials is rotatably mounted on the left wall of the cache silo 31, and 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 Figure 2-Figure 4 The right end of the feed pipe 21 rotates and penetrates into the interior of the cylinder 1. The bottom of the feed pipe 21 is provided with a discharge port located inside the cylinder 1. Several spiral augers 22 use shaftless auger blades. Several spiral augers 22 are coaxial and located between the feed port and the discharge port. A blanking plate 35 is rotatably installed inside the discharge port.

[0031] During specific use, the raw materials are transported to the cache silo 31 through the existing conveying equipment, and the raw materials in the cache silo 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. When driving the rotating component 23, the driving motor 24 will also drive the swing mechanism 33, 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 cache silo 31, which causes the feed pipe 21 to be blocked.

[0032] The raw materials are transported by cooperating with two coaxial spiral augers 22. Compared with the traditional single augers, the distance between the two spiral augers 22 can be continuously adjusted during the rotation, effectively preventing the raw materials from getting stuck during the transportation process.

[0033] See also Figure 2-Figure 4The rotating assembly 23 includes a central shaft 231 rotatably installed at the center of the feed pipe 21, and first turntables 232 symmetrically distributed on the left and right are fixedly installed on the central shaft 231. The feed port and the discharge port are both located between the left and right first turntables 232. A pull rod 233 corresponding to the spiral augers 22 is installed between the left and right first turntables 232 for sliding left and right. The pull rod 233 is fixedly connected to the corresponding spiral augers 22 and is slidably connected to the other spiral augers 22 left and right.

[0034] See also Figure 2-Figure 5 The spacing adjustment component 24 includes a guide groove 241 which is opened on the inner ring wall of the feed tube 21 and is in the shape of an inclined elliptical ring. The guide groove 241 is located on the left side of the first turntable 232 on the left. The left end of the pull rod 233 slides through the left side of the first turntable 232 on the left and is fixedly connected to the guide rod 242. The guide rod 242 slides with the guide groove 241.

[0035] See also Figure 1-Figure 5 , the first turntable 232 is driven to rotate by the central shaft 231, and then the first turntable 232 drives the pull rod 233 and the spiral auger 22 to rotate, so that the spiral auger 22 transports the raw materials in the feed pipe 21 from left to right. During the rotation of the pull rod 233 and the spiral auger 22, the pull rod 233 will drive the corresponding guide rod 242 to rotate circumferentially. At this time, the guide groove 241 is used to guide the guide rod 242, so that the guide rod 242 and the pull rod 233 periodically move back and forth left and right, thereby driving the spiral auger 22 to move left and right during the rotation. Since the two spiral augers 22 are circumferentially distributed, the two spiral augers 22 will move synchronously in opposite directions, thereby continuously adjusting the distance between the two spiral augers 22 to prevent the raw materials from getting stuck during the transportation process.

[0036] See also Figure 2-Figure 4 The spacing adjustment assembly 24 also includes a baffle 243 that is fixedly connected to the right side of the first right turntable 232 after the right end of the pull rod 233 slides through the right side. A second turntable 244 located on the right side of the baffle 243 is fixedly connected to the central axis 231, and a return spring 245 is fixedly connected between the right side of the baffle 243 and the left side of the second turntable 244.

[0037] When the pull rod 233 moves left and right, the pull rod 233 will drive the baffle 243 to move left and right. When the baffle 243 moves to the right, it will compress the return spring 245, and use the rebound force of the return spring 245 to push the pull rod 233 to move left, which is conducive to the spiral auger 22 moving left and returning during the process of conveying raw materials.

[0038] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 8The top of the feed pipe 21 is fixedly connected with a raised shell 211, and the inner cavity of the raised 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 raised 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 by the belt to rotate synchronously, and then the rotating rod 251 drives the shifting rod 252 to rotate, so that the shifting rod 252 periodically shifts the raw materials between the spiral auger 22 downward to prevent the raw materials from being stuck or adhering between the auger blades, thereby ensuring the continuity of raw material transportation; when the shifting rod 252 rotates into the raised shell 211, the shifting rod 252 shrinks under the push of the raised shell 211, and when the shifting rod 252 rotates to the bottom, the two auger blades on both sides of the shifting rod 252 are separated to the maximum state, and the shifting rod 252 extends under the action of its own elastic force, making it convenient for the shifting rod 252 to extend between the two auger blades, which is conducive to the shifting and loosening of the raw materials.

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

[0041] See also Figure 2-Figure 4 The reverse-rotating auger 26 is fixedly mounted on the central shaft 231 and is coaxial therewith. The reverse-rotating auger 26 is located on the left side of the first turntable 232 on the right side 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 excess raw materials will come into contact with the reverse auger 26. The reverse auger 26 is used to transport the excess raw materials to the left in reverse order 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 and ensure the continuity of the operation of the cylinder 1.

[0043] See also Figure 1 、 Figure 2 、 Figure 6 and Figure 7The interior of the cache silo 31 is fixedly installed with an arc-shaped plate 311 located on the right side of the material control plate 32. The top of the cache silo 31 is fixedly connected with a trumpet-shaped feeding nozzle 312. A through hole 321 is opened on the material control plate 32. 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 a limit rod 323 symmetrically distributed front and back. The top of the limit rod 323 slides through the top of the material control plate 32 and is fixedly connected to a stop block.

[0044] By setting up a buffer silo 31 to cache the raw materials, the control plate 32 can swing up and down periodically with the rotation of the spiral auger 22 to control the discharge amount of the raw materials. On the one hand, it avoids excessive raw materials from entering the feed pipe 21 and causing blockage. On the other hand, when the existing feeding equipment has uneven feeding or temporary failure, the cached material can continue to be fed into 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 push of the raw materials above the material control plate 32, so that the raw materials fall below the material control plate 32 through the through hole 321. When the material control plate 32 moves downward, the flap 322 rotates in the opposite direction under the push 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 push the raw materials, thereby preventing the raw materials from accumulating and clogging in the buffer bin 31, thereby improving the raw material unloading efficiency.

[0046] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The swing mechanism 33 includes a crank 331 fixedly mounted on the right side of the output shaft of the driving motor 24, a first connecting rod 332 is rotatably mounted on the crank 331, a second connecting rod 333 is hinged on the top of the first connecting rod 332, the left side of the material control plate 32 extends to the left side of the cache bin 31 and is fixedly connected to a round rod, the top end of the second connecting rod 333 is slidably connected to the round rod left and right, and the right side of the crank 331 is coaxially fixedly connected to the left end of the central axis 231.

[0047] The crank 331 is driven to rotate by the driving motor 24, and the crank 331 drives the control plate 32 to swing back and forth up and down through the transmission of the first connecting rod 332 and the second connecting rod 333. During the reciprocating swing of the control plate 32, the second connecting rod 333 will slide left and right along the round rod. The up and down swing of the control plate 32 is used to control the discharge amount of raw materials in the buffer silo 31, so as to avoid blockage caused by excessive raw materials entering the feed pipe 21.

[0048] See also Figure 1 、 Figure 2 and Figure 6, and also includes a feeding component 34, which includes a feeding roller 341 that is rotatably installed inside the cache bin 31 and is symmetrically distributed on the left and right sides. The feeding roller 341 is located above the arc plate 311, and a driving motor 342 for driving the left feeding roller 341 to rotate is fixedly installed on the front side of the cache bin 31. The rear side of the output shaft of the driving motor 342 is coaxially fixedly connected to the left feeding roller 341, and the rear side of the feeding roller 341 is coaxially fixedly connected to a transmission gear 343 located on the rear side of the cache bin 31, and the left and right transmission gears 343 are engaged with each other.

[0049] The feed roller 341 on the left is driven to rotate by a driving motor 342, and the feed roller 341 on the left drives the feed roller 341 on the right to rotate in the opposite direction through the transmission of two transmission gears 343. The two feed rollers 341 cooperate with each other to transport the raw materials entering the feed nozzle 312 downward, and the feed roller 341 can further crush the raw materials to avoid the situation where the raw materials are too large and get stuck.
