Description
Technical Field
[0001] This application relates to the field of rotary kiln technology, and in particular to a rotary kiln support structure. Background Technology
[0002] A rotary kiln mainly consists of a kiln head, kiln body, kiln tail, and support frame. The kiln body is the main part of the rotary kiln, typically 30-150 meters long, cylindrical in shape, and equipped with 3-5 rolling rings. These rolling rings play a crucial role in the operation of the rotary kiln; they not only support the entire kiln body but also restrict its movement, preventing it from falling off during rotation.
[0003] However, existing rollers are typically fixed directly to the outer wall of the kiln. During prolonged high-temperature operation, the kiln body will experience slight radial displacement due to factors such as thermal expansion. This displacement causes a misalignment between the kiln body and the center of the supporting structure, further leading to wear or deformation of the rollers and support rollers within the supporting structure. As wear and deformation intensify, the kiln body will exhibit significant vibrations, which not only affect the stable operation of the rotary kiln but may also cause irreversible mechanical damage to the supporting structure and the kiln body itself.
[0004] Regarding the aforementioned technologies, the inventors believe that existing support structures are prone to wear and deformation during use, which affects the stable operation of the kiln and can easily cause mechanical damage to the support mechanism and the kiln. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides a rotary kiln support structure.
[0006] This application provides a rotary kiln support structure, which adopts the following technical solution:
[0007] A rotary kiln support structure includes a support base, a mounting base disposed on the support base, a clamping drive assembly disposed on the mounting base, a first support mechanism connected to the clamping drive assembly, a second support mechanism connected to the clamping drive assembly, and a positioning assembly disposed on the kiln body. The first support mechanism includes a first support rod and a first clamping plate connected to the clamping drive assembly. The second support mechanism includes a second support rod and a second clamping plate connected to the clamping drive assembly. A lifting adjustment assembly is disposed on the first support rod, and a rotating rod is disposed on the first clamping plate. The end of the rotating rod away from the first clamping plate is rotatably connected to the lifting adjustment assembly. The second support rod has the same structure as the first support rod, and the second clamping plate has the same structure as the first clamping plate.
[0008] By adopting the above technical solution, the clamping drive assembly drives the first clamping plate and the second clamping plate to move closer to the kiln body, the lifting adjustment assembly adjusts the height of the first clamping plate and the second clamping plate, and the positioning assembly adjusts the angle of the first clamping plate and the second clamping plate, so that the center of the first clamping plate and the second clamping plate are parallel to the central axis of the kiln body, thereby reducing the wear on the first clamping plate and the second clamping plate, reducing the deformation of the first clamping plate and the second clamping plate, and thus improving the safety and stability of the kiln body operation.
[0009] Preferably, the first support rod has an adjustment groove, and an adjustment motor is fixedly connected to the first support rod. The lifting adjustment assembly includes an adjustment screw and an adjustment slider disposed in the adjustment groove. One end of the adjustment screw is fixedly connected to the drive shaft of the adjustment motor, and the other end is rotatably connected to the first support rod. The adjustment slider is threadedly connected to the adjustment screw and slidably connected to the adjustment groove. The adjustment slider is rotatably connected to the rotating rod.
[0010] By adopting the above technical solution, the adjusting motor drives the adjusting screw to rotate, causing the adjusting slider to slide in the adjusting groove, thereby adjusting the height of the first clamping plate.
[0011] Preferably, the positioning component includes a first positioning block and a second positioning block fixedly disposed on the kiln body. The first positioning block has a positioning groove, and the first clamping plate and the second clamping plate are slidably connected to the positioning groove. The second positioning block has the same structure as the first positioning block, and the first positioning block and the second positioning block are symmetrically disposed on the kiln body.
[0012] By adopting the above technical solution, the symmetrically arranged first and second positioning blocks adjust and limit the angle of the first and second clamping plates, so that the center of the first and second clamping plates is parallel to the central axis of the kiln body.
[0013] Preferably, the mounting base has a limiting groove, and the clamping drive assembly includes a transmission motor fixedly mounted on the mounting base, a bidirectional lead screw disposed in the limiting groove, a first slider, and a second slider. One end of the bidirectional lead screw is fixedly connected to the transmission shaft of the transmission motor, and the other end is rotatably connected to the mounting base. The first slider and the second slider are both threadedly connected to the bidirectional lead screw and slidably connected to the limiting groove. The first slider and the second slider are respectively disposed on both sides of the bidirectional lead screw. The first slider is connected to the first support rod, and the second slider is connected to the second support rod.
[0014] By adopting the above technical solution, the drive motor drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the first slider and the second slider to move closer to or further away from each other, thereby causing the first clamping plate and the second clamping plate to move closer to or further away from the kiln body, which facilitates the installation or disassembly of the first support mechanism and the second support mechanism, and at the same time facilitates the maintenance or replacement of the first support mechanism and the second support mechanism.
[0015] Preferably, a first ball bearing assembly is provided on the side of the first clamping plate away from the first support rod, and a second ball bearing assembly is provided on the side of the second clamping plate away from the second support rod. The first ball bearing assembly includes a support block connected to the first clamping plate. A mounting groove is provided on the side of the support block away from the first clamping plate, and a ball bearing is provided in the mounting groove. The ball bearing is rotatably connected to the support block. The second ball bearing assembly has the same structure as the first ball bearing assembly.
[0016] By adopting the above technical solution, the ball bearings reduce the frictional resistance between the first and second clamping plates and the kiln body, thereby making the rotation of the kiln body smoother and reducing the wear on the first clamping plate, the second clamping plate and the kiln body.
[0017] Preferably, the first ball bearing assembly further includes a limiting telescopic rod and a spring. One end of the limiting telescopic rod is connected to the first clamping plate, and the other end is connected to the support block. The spring is sleeved on the outside of the limiting telescopic rod, with one end connected to the first clamping plate and the other end connected to the support block.
[0018] By adopting the above technical solution, the limiting telescopic rod and spring provide elastic support for the ball bearings, ensuring close contact between the ball bearings and the kiln body. When the kiln body undergoes radial displacement during rotation, the ball bearings move with the kiln body, thereby reducing the wear and deformation caused by the radial displacement of the kiln body to the first and second clamping plates. The limiting telescopic rod and spring can absorb the vibration generated by the kiln body, further reducing the impact of the radial displacement of the kiln body on the support structure. The setting of the limiting telescopic rod and spring allows the first clamping plate to be used with kiln bodies of different diameters, thus increasing the flexibility and applicability of the first support mechanism.
[0019] Preferably, the limiting telescopic rod includes a fixed tube connected to the first clamping plate and a sliding rod connected to the support block, wherein the sliding rod is slidably connected to the fixed tube.
[0020] Preferably, a limiting plate is provided at the end of the fixed tube away from the first clamping plate, and a limiting block is provided at the end of the sliding rod away from the support block, and the limiting block is slidably connected to the fixed tube.
[0021] By adopting the above technical solution, the sliding rod is slidably connected to the fixed tube. The setting of the limiting block and the limiting plate restricts the sliding distance of the sliding rod, reduces the phenomenon of separation between the sliding rod and the fixed tube, and thus increases the connection stability between the sliding rod and the fixed tube.
[0022] Preferably, there are multiple first ball bearing assemblies, which are evenly distributed on the first clamping plate, and multiple second ball bearing assemblies, which are evenly distributed on the second clamping plate.
[0023] By adopting the above technical solution, multiple first ball bearing assemblies and second ball bearing assemblies increase the support stability of the first and second clamping plates for the kiln body and reduce the impact of radial displacement of the kiln body on the first and second clamping plates.
[0024] In summary, this application has the following beneficial technical effects:
[0025] 1. This application drives the first support mechanism and the second support mechanism to move by a clamping drive assembly, adjusts the height of the first clamping plate and the second clamping plate by a lifting adjustment assembly, and adjusts and limits the rotation angle of the first clamping plate and the second clamping plate by a positioning assembly, thereby making the center line of the first clamping plate and the second clamping plate parallel to the center line of the kiln body, reducing the wear and deformation of the first support mechanism and the second support mechanism, and thus increasing the safety and stability of the kiln body operation.
[0026] 2. This application adopts a structure with multiple first ball bearing assemblies and second ball bearing assemblies, which reduces the wear on the kiln body, the first clamping plate and the second clamping plate, reduces the deformation of the first clamping plate and the second clamping plate, and further increases the safety and stability of the kiln body operation;
