Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, specifically to a rotary kiln hydraulic thrust roller heat insulation device. Background Technology

[0002] The main function of the hydraulic thrust rollers in a rotary kiln is to control the axial movement of the kiln body, ensuring its stability during operation. The thrust rollers are typically installed on the side of the rotary kiln's tire, and the movement of the kiln body is limited through the contact between the tire and the thrust rollers. When the kiln body's movement exceeds the permissible limit, the thrust rollers will either prevent further movement or signal the operator to take appropriate action.

[0003] However, existing hydraulic thrust rollers are usually installed directly on the support platform below the rotary kiln, lacking heat insulation between the hydraulic thrust roller and the rotary kiln. The heat generated by the rotary kiln directly contacts the hydraulic thrust roller, which, over time, reduces the service life of the components on the hydraulic thrust roller. Therefore, a heat insulation device for the rotary kiln hydraulic thrust roller is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a rotary kiln hydraulic thrust roller heat insulation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary kiln hydraulic thrust roller heat insulation device, applied to the rotary kiln body and mounting platform. The rotary kiln body is suspended above the mounting platform. A tire is fixedly fitted on the outer wall of the rotary kiln body. Two roller bases are provided at the upper end of the mounting platform, located on the bottom sides of the outer circumferential sidewall of the tire. Two hydraulic thrust roller bodies are also provided at the upper end of the mounting platform, located on the other sides of the bottom of the tire. A first heat insulation plate is provided between the rotary kiln body and the two hydraulic thrust roller bodies, and the first heat insulation plate is fixedly connected to the mounting platform by a fixing mechanism.

[0006] As a further preferred embodiment of this technical solution, the first heat insulation plate has an arc-shaped structure.

[0007] As a further preferred embodiment of this technical solution, the fixing mechanism consists of a connecting plate, a slider, a pressure block, a fixing plate, and fixing bolts.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, a rotary kiln hydraulic thrust roller heat insulation device is applied to the rotary kiln body 1 and the mounting platform 2. The rotary kiln body 1 is suspended on the upper end of the mounting platform 2. A tire 3 is fixedly sleeved on the outer wall of the rotary kiln body 1. Two support roller bases 4 are provided at the upper end of the mounting platform 2. The two support roller bases 4 are located on the bottom sides of the outer circular sidewall of the tire 3. Two hydraulic thrust roller bodies 5 are also provided at the upper end of the mounting platform 2. The two hydraulic thrust roller bodies 5 are located on the other sides of the bottom of the tire 3. A first heat insulation plate 6 is provided between the rotary kiln body 1 and the two hydraulic thrust roller bodies 5. The first heat insulation plate 6 has an arc-shaped structure and is fixedly connected to the mounting platform 2 by a fixing mechanism.

[0021] The fixing mechanism consists of a connecting plate 7, a slider 8, a pressure block 11, a fixing plate 12, and fixing bolts 14. The connecting plates 7 are fixedly installed on both sides of the bottom of the first heat insulation plate 6. The sliders 8 are fixedly installed on the bottom of both connecting plates 7. The upper surface of the mounting platform 2 has two sliding grooves 10 that slide and engage with the two sliders 8 respectively. One end of the sliding groove 10 extends to the side wall of the mounting platform 2. Two pressure blocks 11 are fixedly installed on the side wall of the fixing plate 12 near the mounting platform 2. The two pressure blocks 11 slide and engage with the two sliding grooves 10 respectively. Through holes 13 are opened on both sides of the fixing plate 12. Fixing bolts 14 are respectively installed in the two through holes 13. The fixing bolts 14 are threaded into the threaded holes 9 opened on the side wall of the mounting platform 2.

[0022] In use, the two sliders 8 at the bottom of the first heat insulation plate 6 are inserted into the two slide grooves 10 on the mounting platform 2 from the side. Then, the two pressure blocks 11 on the fixing plate 12 are inserted into the two slide grooves 10. The pressure blocks 11 can fix the sliders 8 in the slide grooves 10. Then, the fixing plate 12 is fixed to the side wall of the mounting platform 2 by the cooperation of the fixing bolts 14, the through hole 13 and the threaded hole 9, thereby completing the installation of the first heat insulation plate 6.

[0023] The sum of the lengths of slider 8 and pressure block 11 is equal to the length of groove 10.

[0024] This configuration ensures that the pressure block 11 precisely fixes the slider 8 within the groove 10.

[0025] A second heat insulation plate 15 is provided between the rotary kiln body 1 and the tire 3. The inner wall of the second heat insulation plate 15 is fixedly connected to the outer wall of the rotary kiln body 1, and the outer wall of the second heat insulation plate 15 is fixedly connected to the inner wall of the tire 3.

[0026] The gap between the two first heat insulation boards 6 can be blocked by the second heat insulation board 15.

[0027] Both the first heat insulation board 6 and the second heat insulation board 15 are made of fiberglass.

[0028] As a composite material, the fiberglass rod has both good thermal insulation properties, which can insulate heat, and good strength, ensuring that the connection of the tire 3 will not break.

[0029] This utility model provides a hydraulic thrust roller heat insulation device for rotary kilns, the specific working principle of which is as follows:

[0030] In use, the two sliders 8 at the bottom of the first heat insulation plate 6 are inserted into the two slide grooves 10 on the mounting platform 2 from the side. Then, the two pressure blocks 11 on the fixing plate 12 are inserted into the two slide grooves 10. The pressure blocks 11 can fix the sliders 8 in the slide grooves 10. Then, the fixing plate 12 is fixed to the side wall of the mounting platform 2 by the cooperation of the fixing bolts 14, through holes 13 and threaded holes 9, thus completing the installation of the first heat insulation plate 6. At this time, the first heat insulation plate 6 will be between the rotary kiln body 1 and the hydraulic thrust roller body 5. At the same time, the second heat insulation plate 15 set between the rotary kiln body 1 and the tire 3 can block most of the gap between the two first heat insulation plates 6, thus providing a good heat insulation effect for the hydraulic thrust roller body 5.

[0031] 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.
