Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically a special support for a rotary kiln in cement production. Background Technology

[0002] The rotary kiln in cement production is the core equipment for cement clinker calcination. Its function is to transform raw materials into hydraulic cement clinker through high-temperature chemical reactions. The special support for the rotary kiln refers to the support used to support the overall structure of the rotary kiln and bear the overall weight of the rotary kiln.

[0003] Chinese patent application number CN202120559032.0 discloses a special support for a rotary kiln in cement production, comprising a support plate, a support arc plate, support feet, a rotary kiln, a drive assembly, and a reinforcement assembly. The support arc plates are symmetrically arranged above both ends of the support plate, and each support arc plate is a hollow cavity with an open upper end. The support feet are located below and above the support arc plates. The rotary kiln is located at the open end of the support arc plate. The drive assembly includes a gear plate, a drive motor, and a rotary gear. The gear plate is located on the side wall of the rotary kiln and between the support arc plates. This utility model belongs to the field of cement production technology, specifically providing a special support for a rotary kiln in cement production that provides a drive assembly to drive the rotary kiln to rotate at a uniform speed, facilitating the uniform calcination of cement clinker. The reinforcement assembly enhances the stability of the support arc plates and improves the stability of the rotary support. This design is highly practical, easy to operate, structurally stable, runs smoothly, and offers high stability and safety.

[0004] Existing technology essentially designs the rotary kiln's dedicated support as a bearing-like mechanism to make the kiln's rotation more stable. However, in actual operation, the various support rollers of the rotary kiln need to maintain strict parallelism and levelness, making the bearing structure more sensitive to installation accuracy. If the concentricity deviation between the support roller shaft and the bearing housing exceeds the specified value, it will cause the bearing to be unbalanced and jammed, accelerating wear and failing to meet the high-precision installation requirements of the rotary kiln.

[0005] In summary, this utility model provides a special support for rotary kilns in cement production to solve the above problems. Utility Model Content

[0006] This utility model provides a special support for rotary kilns in cement production, which solves the problem that the existing supports cannot meet the requirements for high-precision installation by flexibly adjusting the position of the rotary kiln.

[0007] The specific technical solution of this utility model is as follows:

The output end of the servo electric cylinder 23 is fixedly connected to the telescopic column 22. A transmission groove 221 is opened on the side of the telescopic column 22. The end of the rotating clamping plate 21 near the telescopic column 22 is located inside the transmission groove 221. An arc-shaped base 3 is provided on the side of the rotary kiln main body 1 away from the positioning column 2.

[0030] One end of the arc-shaped base 3 is rotatably connected to a connecting arc plate 31. The end of the connecting arc plate 31 away from the arc-shaped base 3 is rotatably connected to an arc-shaped cover plate 32. The end of the arc-shaped cover plate 32 away from the connecting arc plate 31 is rotatably connected to a locking plate 33. The middle of the locking plate 33 is rotatably connected to a locking ring 34. The end of the locking ring 34 away from the locking plate 33 is rotatably connected to the arc-shaped base 3.

[0031] A first support column 24 is fixedly connected to the lower part of the positioning column 2, and a first slide table 4 is fixedly connected to the bottom end of the first support column 24.

[0032] A second support column 35 is fixedly connected to the bottom of the arc-shaped base 3, and the bottom end of the second support column 35 is fixedly connected to the first slide table 4.

[0033] A first base 41 is provided below the first slide table 4. A first servo motor 42 is provided on one side of the first base 41. A first lead screw 43 is fixedly connected to the output end of the first servo motor 42. The first lead screw 43 is rotatably connected to the first base 41. The first lead screw 43 is connected to the first slide table 4 through a ball screw.

[0034] A second slide 5 is fixedly connected to the lower part of the first base 41, and a second base 51 is provided below the second slide 5.

[0035] A second servo motor 52 is provided on the side of the second base 51. A second lead screw 53 is fixedly connected to the output end of the second servo motor 52. The second lead screw 53 is connected to the second slide table 5 through a ball screw.

[0036] The end of the second lead screw 53 away from the second servo motor 52 is rotatably connected to a fixed frame 6, and the fixed frame 6 is fixedly connected to the second base 51.

[0037] The working principle of this utility model is as follows: In the initial state, the servo cylinder 23 is in the extended state, the telescopic column 22 is located at the initial position of the center of the positioning column 2, the transmission groove 221 and the mating end of the rotating clamp 21 are in an open state, the rotating clamp 21 does not clamp the rotary kiln body 1, and the locking ring 34 and locking plate 33 of the arc-shaped base 3 are in an open state so that the rotary kiln body 1 can be initially placed; after the rotary kiln body 1 is placed between the positioning column 2 and the arc-shaped base 3, the control system starts the servo cylinder 23, and its output end pushes the telescopic column 22 to slide along the central axis of the positioning column 2. The transmission groove 221 on the side of the telescopic column 22 moves with the column, causing the end of the rotating clamp 21 near the telescopic column 22 to rotate in the groove. The rotating clamp 21 rotates around the positioning column 22. The hinge point on the side of column 2 rotates and gradually retracts towards the outer periphery of the rotary kiln body 1, simultaneously clamping the rotary kiln body 1 from multiple directions to align its axis with the center of the positioning column 2. During installation, the locking ring 34 initially rotates around the arc-shaped base 3 to the outside, causing the locking plate 33 to unfold outward. The arc-shaped cover plate 32 forms an open space with the arc-shaped base 3 through the connecting arc plate 31, making it easy for the other end of the rotary kiln body 1 to fall into the support surface of the arc-shaped base 3. After the positioning column 2 completes clamping, the locking ring 34 rotates inward. The locking plate 33 pulls the arc-shaped cover plate 32 along the rotation trajectory of the locking ring 34. Through the hinge linkage of the connecting arc plate 31, an arc-shaped wrapping is formed around the other end of the rotary kiln body 1. The locking ring 34 rotates to the locking position and is fixed, completing the locking of the two-way support structure.

[0038] The overall process is as follows: the rotary kiln body 1 is moved to the target area for initial alignment by the linkage of the first slide table 4 and the second slide table 5; the servo electric cylinder 23 is started to clamp the kiln body 1 by rotating the clamping plate 21; the locking ring 34 is rotated to drive the arc-shaped cover plate 32 to close and lock the kiln body; if fine adjustment is required, the kiln body is moved by the dual slide table system to complete the installation. This process achieves high-precision positioning, rapid installation and adaptability to different working conditions.
