Description

Technical Field

[0001] This utility model relates to the field of high-temperature industrial technology, specifically a high-temperature working roller with a built-in noise reduction structure. Background Technology

[0002] In high-temperature industrial fields such as metallurgy, glass manufacturing, and ceramic sintering, rollers, as core conveying and processing components, are subjected to high-temperature environments above 1000℃ for a long time. When traditional high-temperature rollers operate under high-temperature conditions, they generate noise, which not only damages the hearing health of operators, but also causes measurement errors in the precision sensors of surrounding equipment, seriously affecting the accuracy of automated control of the production line.

[0003] Traditional high-temperature rollers generate low-frequency noise due to intensified surface vibration under high-temperature conditions. Although external noise-absorbing structures can block noise transmission to some extent, their effectiveness in suppressing low-frequency noise is poor. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature working roller with a built-in noise reduction structure, which solves the problem mentioned in the background art that the external noise reduction structure of traditional high-temperature rollers has a poor suppression effect on low-frequency noise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature working roller with a built-in noise reduction structure, comprising a fixing member and a central shaft, wherein a chamber is fixedly connected to the side wall of the fixing member, and the two ends of the central shaft pass through the side walls of the chamber at both ends and are rotatably connected to the side wall surface of the fixing member, wherein a plurality of impeller blades are fixedly connected in a circumferential array on the surface of the inner part of the central shaft located inside the chamber, and the inner side of the chamber is filled with a viscous silicon-based high-temperature fluid.

[0006] In this technical solution, chambers are set on both sides of the central shaft, and the chambers are filled with viscous silicon-based high-temperature fluid. When the central shaft and the outer roller shell rotate, the impeller blades on the surface of the central shaft will cut the viscous silicon-based high-temperature fluid in the chamber. The low-frequency vibration generated during the rotation of the outer roller shell and the central shaft is converted into heat energy by the shear eddy current effect, thereby achieving the vibration reduction effect and reducing low-frequency noise.

[0007] Preferably, the outer wall of the compartment is fixedly connected with a number of heat dissipation fins in a circumferential array, and the central shaft is rotatably connected to the compartment through a bearing seat.

[0008] Preferably, two sets of support frames are fixedly connected to the outer side wall of the central shaft, and an outer roller shell is fixedly connected to the outer end of the support frame.

[0009] Preferably, several interference vanes are fixedly connected in a circumferential array on the inner sidewalls at both ends of the outer roller shell, and the interference vanes are located outside the heat dissipation fins.

[0010] Preferably, a plurality of polyester fiber sound-absorbing panels are fixedly connected to the inner sidewall of the outer roller shell, and the polyester fiber sound-absorbing panels are located between the gaps of the support frame.

[0011] Preferably, a number of fan blades are fixedly connected in a circular array at the center of the outer surface of the central shaft, and sound-absorbing cotton is fixedly connected to the side walls of the two support frames on the outer surface of the central shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model sets up chambers on both sides of the central shaft, and fills the chambers with viscous silicon-based high-temperature fluid. When the central shaft and the outer roller shell rotate, the impeller blades on the surface of the central shaft will cut the viscous silicon-based high-temperature fluid in the chamber. The low-frequency vibration generated during the rotation of the outer roller shell and the central shaft is converted into heat energy by the shear eddy current effect, thereby achieving the vibration reduction effect and reducing low-frequency noise.

[0014] 2. During the rotation of the central shaft, the fan blades on the surface of this invention will rotate accordingly, thereby generating airflow, which assists the heat dissipation fins on the outer side wall of the compartment to dissipate heat, improves the heat dissipation effect, and keeps the temperature of the viscous silicon-based high-temperature fluid within a certain range, thereby achieving continuous heat absorption and vibration reduction and noise reduction effects.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A high-temperature working roller with a built-in noise reduction structure, see [link / reference]. Figures 1 to 4 The device includes a fixing component 1 and a central shaft 2. A chamber 5 is fixedly connected to the side wall of the fixing component 1. The two ends of the central shaft 2 pass through the side walls of the chamber 5 at both ends and are rotatably connected to the side wall surface of the fixing component 1. The chamber 5 is fixed. A bearing seat with a sealing component is provided at the position where the central shaft 2 passes through the chamber 5, so as to ensure the normal rotation of the central shaft 2 while preventing the leakage of the viscous silicon-based high-temperature fluid 7 inside. Several impeller blades 6 are fixedly connected in a circumferential array on the surface of the part of the central shaft 2 located inside the chamber 5. The inside of the chamber 5 is filled with viscous silicon-based high-temperature fluid 7. When the central shaft 2 and the outer roller shell 4 rotate, the impeller blades 6 rotate with it, cutting the viscous silicon-based high-temperature fluid 7 inside the chamber 5. The low-frequency vibration generated during the rotation of the outer roller shell 4 and the central shaft 2 is converted into heat energy by the shear eddy current effect, thereby achieving the vibration reduction effect and reducing low-frequency noise.

[0023] It is worth mentioning that the viscous silicon-based high-temperature fluid 7, such as dimethyl silicone oil modified composite material, will reserve space for thermal expansion when the fluid is filled, so it does not need to be filled completely; when rotating, the impeller blades 6 on the surface of the central shaft 2 inside the chamber 5 rotate, the impeller blades 6 cut the fluid, and the fluid generates violent shearing motion due to viscous resistance. Mechanical energy is converted into heat energy through viscous friction, thereby dissipating the energy generated by vibration and reducing the generation of noise.

[0024] Specifically, such as Figure 2 As shown, several fan blades 11 are fixedly connected in a circular array in the center of the outer surface of the central shaft 2. During the rotation of the central shaft 2, the fan blades 11 on its surface will rotate accordingly, thereby generating airflow. This helps the heat dissipation fins 8 on the outer wall of the auxiliary chamber 5 to dissipate heat, thus improving the heat dissipation effect. The side walls of the two support frames 3 on the outer surface of the central shaft 2 are fixedly connected with sound-absorbing cotton 12. The sound-absorbing cotton 12 can block the whistling sound during the airflow process, thereby reducing noise.

[0025] Furthermore, such as Figure 3 and Figure 4 As shown, the outer wall of the chamber 5 is fixedly connected with several heat dissipation fins 8 in a circumferential array. The central shaft 2 is rotatably connected to the chamber 5 through a bearing seat. Several turbulence deflectors 9 are fixedly connected in a circumferential array on the inner wall of both ends of the outer roller shell 4. The turbulence deflectors 9 are located outside the heat dissipation fins 8. During the cutting process of the impeller blades 6, the heat of the chamber 5 will increase. The heat dissipation fins 8 dissipate heat on the outside. The airflow generated by the rotation of the fan blades 11 will pass through the heat dissipation fins 8, thereby accelerating the removal of heat from the surface of the heat dissipation fins 8 and improving the heat dissipation effect. In addition, the rotation of the outer roller shell 4 drives the turbulence deflectors 9 to turbulent the airflow, thereby further improving the heat dissipation efficiency of the heat dissipation fins 8.

[0026] It is worth noting that, such as Figure 2 and Figure 3 As shown, two sets of support frames 3 are fixedly connected to the outer side wall of the central shaft 2. The outer end of the support frame 3 is fixedly connected to the outer roller shell 4. Several sets of polyester fiber sound-absorbing panels 10 are fixedly connected to the inner side wall of the outer roller shell 4. The polyester fiber sound-absorbing panels 10 are located between the gaps of the support frame 3. The polyester fiber sound-absorbing panels 10 are formed by hot pressing of polyester fibers and have both sound absorption and certain heat insulation properties. The gaps between its fibers can store air to form a heat insulation layer, which can block the heat from entering the surface of the outer roller shell 4 to a certain extent, so that the air temperature inside decreases, thus making it easier to cool down during flow.

[0027] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
