Description

Technical Field

[0001] This utility model relates to the field of drying kiln technology, specifically to an adjustable drying kiln lifting plate angle optimization device. Background Technology

[0002] The RKEF process uses a drying kiln to dry laterite nickel ore, reducing the moisture content of laterite nickel ore from 35% to 40% to 20% to 22%. The heat transfer method of the drying kiln is that the gas and the material are in direct contact inside the cylinder. Lifting plates are installed inside the rotating cylinder to ensure that the material is lifted and evenly distributed across the entire cross-section of the cylinder, thereby increasing the contact area between the material and the hot gas.

[0003] In existing technologies, in the structural design of traditional drying kilns, the lifting plates are usually installed at a fixed angle inside the drying kiln drum. After the material enters the drying kiln drum, it is lifted and thrown by the lifting plates at a fixed angle, so that it comes into contact with hot air for drying.

[0004] Because the angle of the lifting plates is fixed and cannot be adjusted, when processing materials with high moisture content, the fixed angle of the lifting plates cannot increase the lifting height and the dispersion of the falling material, resulting in insufficient contact between the material and the hot air, low drying efficiency, and uneven drying. When processing materials that are sensitive to drying temperature and time, the material movement trajectory and residence time cannot be adjusted by changing the angle of the lifting plates, which can easily cause local overheating or insufficient drying of the material, seriously affecting product quality and making it difficult to meet diverse drying needs.

[0005] In light of this, we have introduced an adjustable drying kiln lifting plate angle optimization device. Utility Model Content

[0030] Please see Figure 1-4 This utility model provides a technical solution: an adjustable drying kiln lifting plate angle optimization device, including: a base 1, a column 7 is provided on one side of the top of the base 1, and a drying kiln roller 5 is provided on one side of the column 7 above the base 1.

[0031] A gear ring 6 is disposed on one side of the surface of the drying kiln drum 5. The gear ring 6 is fixedly connected to the surface of the drying kiln drum 5, and a gear 14 is engaged at the bottom of the gear ring 6.

[0032] Connecting rods 51 are evenly spaced inside the drying kiln drum 5. One side of the connecting rods 51 is provided with an inner sleeve 52 inside the drying kiln drum 5. An annular heating tube 53 is provided inside the inner sleeve 52.

[0033] The inner wall of the inner sleeve 52 is provided with an adjustment mechanism. The bolts 19 of the adjustment mechanism are used to release the fixing of the lifting plate 16 so that the lifting plate 16 can change different positions within the inner sleeve 52.

[0034] The adjusting mechanism includes a positioning ring 17 connected to the inner wall of the inner sleeve 52. The positioning ring 17 is fixedly installed to the inner wall of the inner sleeve 52. The lifting plate 16 is rotatably connected to the inside of the positioning ring 17. The surface of the positioning ring 17 has equally spaced screw holes 18 for screwing. The screw holes 18 and the positioning ring 17 are integrally formed. The bolt 19 passes through the screw holes 18 and is connected to the inside of the lifting plate 16. The lifting plate 16 can rotate inside the positioning ring 17 to change to different positions. After adjusting the angle, the bolt 19 is tightened for fixation (e.g., ...). Figure 3 As shown in the figure, the lifting plates 16 at different angles can change the lifting height and falling trajectory of the material, thereby optimizing the contact effect between the material and the hot air.

[0035] The inner sleeve 52 is internally connected to a temperature sensor 57, and the model of the temperature sensor 57 can be selected as: DS18B20 or MAX31855 (with thermocouple amplifier), etc.

[0036] The connecting rod 51 contains a power supply for driving the annular heating tube 53. The wire harness passes through the connecting rod 51 to connect the annular heating tube 53 to the temperature sensor 57. The wire harness is made of silicone rubber or PTFE high-temperature resistant sheath (temperature resistance ≥200℃).

[0037] The inner side of the column 7 is connected to a motor A12. A support block is provided at the bottom of the motor A12 and is used to support the motor A12. A rotating shaft 15 is provided between the output end of the motor A12 and the base 1, and a gear 14 is fixedly connected to the surface of the rotating shaft 15.

[0038] A rotating rod 10 is connected to one side of the column 7. A bearing is connected between the rotating rod 10 and the column 7, and the rotating rod 10 extends into the interior of the drying kiln drum 5. A motor B20 is installed inside the column 7 on one side of the rotating rod 10. A concave positioning frame 13 is installed between the column 7 and the rotating rod 10.

[0039] The rotating rod 10 has a rotating shaft 55 located inside the drying kiln drum 5. Stirring rods 56 are evenly spaced on the surface of the rotating shaft 55. When the stirring rods 56 and the rotating shaft 55 rotate clockwise, the material is stirred, resulting in a more uniform distribution of the material during drying, preventing localized overheating or insufficient drying, and further improving the drying effect. Simultaneously, when the stirring rods 56 and the rotating shaft 55 are driven in reverse by the motor B20, the heated laterite nickel ore is discharged from the feed inlet using the stirring rods 56 and the rotating shaft 55 (i.e.,...). Figure 1 On the other side of the drying kiln drum 5, the processed laterite nickel ore can also be discharged through the inspection door 2, which is also installed on the inner sleeve 52 and aligned with the drying kiln drum 5.

[0040] The top of the base 1 is connected to a support roller 4, and the surface of the drying kiln drum 5 is connected to a support roller 3, which is rotatably connected inside the support roller 4. The support roller 4 connected to the top of the base 1 cooperates with the support roller 3 on the surface of the drying kiln drum 5, and the support roller 3 is rotatably connected inside the support roller 4. Figure 1 As shown, a baffle 23 (i.e., the right side of the drying kiln drum 5) is connected to the side of the base 1. A U-shaped drum support 21 is also installed on the right side of the base 1. The upper end of the drum support 21 is engaged with the bearing 22 at the center of the baffle 23 on the right end of the drying kiln drum 5. The support roller 4, the support roller 3, the drum support 21 and the bearing 22 together support the drying kiln drum 5 and ensure that it can rotate stably.

[0041] The sides of the baffle frame 23 and the U-shaped roller support 21 are connected by screws. The baffle frame 23 and the U-shaped roller support 21 can be unscrewed to release the fixation of the baffle frame 23 and the U-shaped roller support 21. After disassembling the baffle frame 23 and the roller support 21, the right end of the drying kiln roller 5 can be loaded and unloaded, making it more convenient to use.

[0042] The surface of the drying kiln drum 5 is provided with an inspection door 2. The inspection door 2 on the surface of the drying kiln drum 5 facilitates the operation of workers to adjust the angle of the lifting plate 16 or to feed materials. The main discharge is still through the right side of the drying kiln drum 5.

[0043] Specifically, during use, when the device is started, the motor A12 inside the column 7 starts working. The output end of the motor A12 drives the rotating shaft 15 to rotate. Since the gear 14 is fixedly connected to the surface of the rotating shaft 15, the rotation of the rotating shaft 15 will drive the gear 14 to rotate together. The gear 14 meshes with the gear ring 6 on one side of the surface of the drying kiln drum 5. The rotation of the gear 14 is transmitted to the drying kiln drum 5 through the gear ring 6, so that the drying kiln drum 5 rotates around its own axis. When the motor B20 starts, it will drive the rotating rod 10, the rotating shaft 55 and the stirring rod 56 to rotate. A mechanical seal is provided between the rotating rod 10 and the drying kiln drum 5 for easy sealing.

[0044] Moist material enters from the feed inlet of the drying kiln drum 5 or is fed into the inside of the inspection door 2 and then the inspection door 2 is closed. As the drying kiln drum 5 rotates, the material is lifted to a certain height by centrifugal force and the lifting plate 16, and then falls under the action of gravity. During this process, the material comes into full contact with the hot air inside the drying kiln drum 5 to achieve preliminary drying.

[0045] The angle of the lifting plate 16 can be adjusted via an adjustment mechanism. Specifically, the bolt 19 is loosened. The bolt 19 passes through the screw hole 18 on the surface of the positioning ring 17 and connects to the inside of the lifting plate 16. After loosening the bolt 19, the lifting plate 16 can rotate inside the positioning ring 17, changing to different positions. After adjusting the angle, the bolt 19 is tightened again to fix it in place. Figure 3 As shown in the state), the lifting plates 16 at different angles can change the lifting height and falling trajectory of the material, thereby optimizing the contact effect between the material and the hot air, and thus drying the laterite nickel ore with a moisture content of 35% to 40% to 20% to 22% inside the drying kiln drum 5.

[0046] An annular heating tube 53 is installed inside the inner sleeve 52. The power supply for the annular heating tube 53 is driven by the internal part of the connecting rod 51. The wiring harness passes through the connecting rod 51 and connects the annular heating tube 53 to the temperature sensor 57, thus creating an electrical connection. This allows the annular heating tube 53 and the temperature sensor 57 to work. The heat generated by the annular heating tube 53 is transferred through the inner sleeve 52 to the inside of the drying kiln drum 5 and comes into contact with the material, creating a high-temperature environment inside to provide heat for drying the material. At the same time, the rotation of the rotating rod 10 drives the rotating shaft 55 and the stirring rod 56 to rotate. The stirring rod 56 stirs the material, making the material more evenly distributed during the drying process, avoiding local overheating or insufficient drying, and further improving the drying effect.

[0047] The temperature sensor 57 connected inside the inner sleeve 52 can monitor the temperature inside the drying kiln drum 5 in real time and feed the temperature data back to the control system. When the temperature is too high or too low, the control system can adjust the heating power of the annular heating tube 53 according to the preset temperature range to keep the temperature inside the drying kiln drum 5 within a suitable range, ensuring the stability of the material drying process and the quality of the product.

[0048] The support roller 4 connected to the top of the base 1 cooperates with the support roller 3 on the surface of the drying kiln drum 5. The support roller 3 is rotatably connected inside the support roller 4. The support roller 4 and the support roller 3 together support the drying kiln drum 5 and ensure its stable rotation. The inspection door 2 opened on the surface of the drying kiln drum 5 facilitates the operation of workers to adjust the angle of the lifting plate 16 or to feed materials.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
