Description

Technical Field

[0001] This invention relates to the field of rotary kiln measurement technology, and in particular to a rotary kiln cylinder centerline measurement and adjustment device. Background Technology

[0002] The centerline of the rotary kiln shell is an important installation parameter for the rotary kiln. Whether the deviation of the centerline meets the requirements is related to the stress on the kiln shell and the support rollers, and whether the rotary kiln can operate safely and stably. Therefore, the accurate measurement of the centerline deviation is also crucial, and sensors are required in the measurement process.

[0003] A search of Chinese invention patents revealed that the invention, with publication number CN119334132B and titled "Rotary Kiln Shell Centerline Measurement and Adjustment Device," involves rotating a handle to drive an inner rotating rod. Through the cooperation of the pushing rod and the inner sliding seat, one end of each of the two sets of support seats slides into the support housing. At this point, a crane lifts the measuring device assembly into the rotary kiln. Releasing the handle allows the restoring force of the telescopic spring to ensure that the ends of the two sets of support seats are tightly pressed against the inner wall of the rotary kiln, significantly improving the stability of the measuring device assembly.

[0004] However, in practical use, similar solutions in the existing technology still have some problems: 1. Currently, some methods for measuring the centerline of rotary kiln shells require operation inside the shell. However, this method has obvious limitations. As the internal temperature of the rotary kiln rises significantly during operation, the high-temperature environment poses a great challenge to both the measuring equipment and the personnel. Therefore, it is only suitable for the installation stage and cannot meet the measurement needs under working conditions. 2. During the operation of the rotary kiln cylinder, the existing technology lacks intuitive means of observing the offset, making it difficult for operators to obtain cylinder offset information in a timely and accurate manner. This results in the inability to react and adjust to the cylinder offset quickly, affecting the stability and safety of the rotary kiln operation and increasing potential risks in the production process. 3. During the operation of the rotary kiln shell, the existing alarm mechanism has shortcomings. It lacks a mechanical warning mechanism as a redundancy guarantee. Once the electronic alarm system is damaged, the operator will lose the key source of alarm information and will not be able to quickly judge the status of the shell, which may delay the opportunity to deal with the fault and thus lead to more serious production accidents.

[0016] Compared with the prior art, the present invention provides a rotary kiln cylinder centerline measuring and adjustment device, which has the following beneficial effects: 1. This rotary kiln cylinder centerline measurement and adjustment device, when the rotary kiln cylinder tilts, will push one side of the contact wheel to move, and the other side of the contact wheel will follow the rotary kiln cylinder to move, driving the moving rod to move. The telescopic measuring end of the telescopic displacement sensor will follow the moving rod, thereby determining the offset direction of the rotary kiln cylinder through a pair of telescopic displacement sensors, thus measuring the offset direction of the rotary kiln cylinder centerline, which is convenient for adjusting the position of the support roller on one side of the rotary kiln cylinder, thereby correcting the rotary kiln cylinder. The telescopic displacement sensor converts the offset information into a digital signal for easy recording. The internal temperature of the rotary kiln cylinder is high when it is working, and the measurement can be carried out during the operation of the rotary kiln through the contact wheel and the telescopic displacement sensor.

[0017] 2. The rotary kiln cylinder centerline measuring and adjustment device, when the slider slides, drives the scale rod to slide. A scale ring is fixed on the scale rod. The scale ring will move closer to a stop block on one side. The scale rod is engraved with graduations. The graduations can be read through the stop block, making it easy to intuitively determine the distance the scale ring has moved. This facilitates the adjustment of the position of the support roller on one side of the rotary kiln cylinder. Adjusting the distance between the stop block and the scale ring can reduce the distance to the minimum allowable deviation. When the scale ring deviates beyond the limit, the scale ring will contact the stop block, indicating that the deviation exceeds the allowable limit, which is convenient for the staff to make a quick judgment.

[0018] 3. When the offset of the rotary kiln cylinder centerline measuring and adjusting device exceeds the allowable limit, the standard ring will push the stop block to slide, causing the moving frame to slide. The fifth spring will drive the control block to slide, and the connecting rod will cause one end of the insertion rod to pass through the insertion hole and extend into the fixed shell. The rotary kiln cylinder will drive the rotating rod to rotate, which will drive the sound spring to rotate. Due to the extension of the insertion rod end, the sound spring will collide with the insertion rod end when it rotates, thereby producing a sound. This makes it easier for the staff to quickly judge the state of the rotary kiln cylinder by sound, making the judgment method simpler. Attached Figure Description

[0029] Embodiment 3: On the basis of Embodiment 2, a measuring and adjusting device for the center line of a rotary kiln cylinder body. A warning mechanism 3 is connected to the fixing plate 21. The warning mechanism 3 includes a fixing shell 313. The fixing shell 313 is installed on the fixing plate 21. A rotating rod 314 is rotatably connected inside the fixing shell 313. A sound spring 318 is installed on the rotating rod 314. A plug rod 315 is rotatably connected to the outside of the fixing shell 313. The end of the plug rod 315 is used to abut against the end of the sound spring 318. The moving frame 45 is connected to the plug rod 315. By the sound of the sound spring 318, it is convenient to alarm when the offset of the rotary kiln cylinder body exceeds the limit.

[0030] In the present invention, there are a pair of plug rods 315. The pair of plug rods 315 are respectively connected to two moving frames 45. The plug rod 315 has a "C" - shaped structure. The middle section of the plug rod 315 is rotatably connected to the fixing shell 313. The fixing shell 313 is provided with jack holes 317 at the ends of each plug rod 315.

A fourth spring 310 is installed between the installation rod 35 and the fixing seat 36. The top of the installation rod 35 is rotatably connected to a transmission wheel 34. The transmission wheel 34 is used to abut and roll against the outer wall of the rotary kiln cylinder body. A first pulley 31 that rotates synchronously is installed on the axle of the transmission wheel 34. A second pulley 32 is installed on the rotating rod 314. A belt 33 is wound and connected between the first pulley 31 and the second pulley 32. Using the rotary kiln cylinder body as a power source, there is no need to configure an additional driving mechanism, effectively saving energy.

[0033] In the present invention, a pair of sliding bars 38 are slidably connected to the fixing seat 36. A third spring 37 is installed between the pair of sliding bars 38. A third pulley 39 is rotatably connected to the sliding bar 38. The third pulley 39 is wound and connected to the belt 33. The pair of third pulleys 39 are located inside the belt 33, so as to ensure the stability of the transmission.

[0034] It should be noted that there is an unclear expression "背离于移动框45的一端固定连接有控制块312" in the original text. I have translated it as best as possible according to the context, but it may need to be further confirmed according to the accurate meaning.In this invention, a pair of abutting wheels 23 are located on the bottom sides of the outer wall of the rotary kiln shell. The abutting wheels 23 are inclined and their axis is parallel to the axis of the rotary kiln shell. When the rotary kiln shell is in operation, it is in an inclined state. The parallelism of the axis of the abutting wheels 23 facilitates the pushing of the rotary kiln shell.

[0035] Working principle: During the operation of the rotary kiln, the base 1 is installed below the rotary kiln shell. Rotating the knob 24 releases the limit on the telescopic rod 25. Under the action of the compressed second spring 29, the telescopic rod 25 is pushed upwards, causing a pair of contact wheels 23 to contact the surface of the rotary kiln shell. Tightening the knob 24 limits the telescopic rod 25 and compresses the first spring 28. When the rotary kiln shell tilts, it pushes one side of the contact wheel 23 to move, causing the telescopic rod 25, the moving rod 22, and the slider 27 to slide. When the spring 28 is compressed, the abutment wheel 23 on the other side will move with the rotary kiln body under the push of the first spring 28. When the moving rod 22 moves, the telescopic measuring end of the telescopic displacement sensor 26 will move with the moving rod 22. Thus, the offset direction of the rotary kiln body can be determined by a pair of telescopic displacement sensors 26, thereby measuring the offset direction of the center line of the rotary kiln body. This makes it easier to adjust the position of the support wheel on one side of the rotary kiln body, thereby correcting the rotary kiln body. The telescopic displacement sensor 26 is connected to the control computer host for easy recording. When the slider 27 slides, it drives the scale rod 43 to slide. A scale ring 47 is fixed on the scale rod 43. The scale ring 47 will move closer to the stop block 46 on one side. The scale rod 43 is engraved with graduations, which can be read through the stop block 46, making it easy to intuitively determine the distance the scale ring 47 has moved. This facilitates the adjustment of the position of the support roller on one side of the rotary kiln. After the base 1 is installed and the contact wheel 23 is adjusted, the adjusting wheel 44 is rotated through the observation window 42, driving the scale rod 43 to rotate. This causes the scale rod 43 to move into or out of the slider 27, thereby adjusting the scale ring 47. The position of the gauge ring 47 is such that it can be positioned in the middle of a pair of stops 46 for calibration, thus avoiding deviations during reading. At the same time, rotating the worm gear 41 drives the worm wheel 49 to rotate, which in turn drives the gear 410 to rotate, causing a pair of racks 48 to move. This causes the pair of stops 46 to slide towards or away from each other, making it easy to adjust the distance between the stops 46 and the gauge ring 47. The distance can be adjusted to the minimum allowable deviation. When the gauge ring 47 deviates beyond the limit, it will contact the stops 46, indicating that the deviation exceeds the allowable limit, which is convenient for staff to make a quick judgment. When the offset exceeds the allowable limit, the standard ring 47 will push the stop block 46 to slide. Due to the unidirectional transmission between the worm gear 41 and the worm wheel 49, the rack 48 cannot drive the gear 410 to rotate in the reverse direction, thereby causing the stop block 46 to drive the rack 48 and the moving frame 45 to slide. The fifth spring 311 drives the control block 312 to slide. The control block 312 pulls or pushes the insertion rod 315 to rotate through the connecting rod 316, so that one end of the insertion rod 315 passes through the insertion hole 317 and extends into the fixed shell 313. Under the action of the fourth spring 310, the mounting rod 35 is pushed to move upward, so that the transmission wheel 34 always remains in contact with the outer wall of the rotary kiln shell. When the rotary kiln shell rotates, it drives the transmission wheel 34 to rotate, which in turn drives the coaxial first pulley 31 to rotate. Driven by belt 33, the second pulley 32 rotates, which in turn drives the rotating rod 314 to rotate, thereby driving the sound spring 318 inside the fixed shell 313 to rotate. Due to the insertion of the end of the insertion rod 315, the sound spring 318 will collide with the end of the insertion rod 315 when it rotates, thus producing a sound. This makes it easier for workers to quickly judge the state of the rotary kiln body by sound, making the judgment method simpler. When the rotary kiln body deviates, it will push the transmission wheel 34 and the first pulley 31 to move. The compressed third spring 37 pushes a pair of sliding bars 38 to move in opposite directions, causing a pair of third pulleys 39 to come into close contact with the inner side of the belt 33, thereby keeping the belt 33 taut and preventing the belt 33 from slipping, ensuring the effective transmission of the belt 33.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
