Technical Field

[0001] The utility model relates to the technical field of roller devices, in particular to a polymer heat-resistant roller. Background Art

[0002] Belt conveyors are widely used transportation equipment in various production lines. They run at high speed, smoothly, and with low noise. They have the advantages of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient program control and automatic operation. When conveying materials with higher temperatures, such as when conveying clinker in the clinker workshop of a cement plant, the temperature of the clinker can be as high as about 180°, and when conveyors convey coke in the coking plant of a steel plant, the temperature can be as high as about 200°. The existing ordinary rollers will be severely deformed by the high temperature, resulting in a significant increase in the conveying friction, making it impossible to carry out normal material conveying. Utility Model Content

[0003] The utility model aims to provide a polymer heat-resistant roller which is suitable for the transportation of high-temperature materials, ensures normal transportation and solves the problems in the prior art.

A limit cover is installed on the roller body outside the bearing, and a rotating shaft is installed between the two bearings. The rotating shaft is located inside the insulation ring layer. The outer periphery of the roller body is provided with a plurality of spaced metal rings, and each metal ring is provided with a polymer heat-resistant sleeve. The inner periphery of the roller body is provided with a plurality of circumferentially arranged slots, and the outer periphery of the insulation ring layer is provided with a block that matches the slot. The metal ring is spot-welded and fixed to the roller body, and the lengths of the metal ring and the polymer heat-resistant sleeve at the corresponding position are consistent, and the distance between adjacent metal rings is 40 mm. The outer periphery of the roller body between adjacent metal rings is provided with a heat dissipation ring, and the outer periphery of the heat dissipation ring is provided with circumferentially arranged heat dissipation fins, the height of the heat dissipation fins is lower than the thickness of the polymer heat-resistant sleeve ring, and the outer side of the metal rings at both ends of the length direction of the roller body is provided with a limit ring. The limit cover is provided with a circumferentially arranged heat dissipation ring groove, the thickness of the metal ring is 5-10mm, and the thickness of the polymer heat-resistant sleeve ring is 15-25mm.

[0005] The positive effect of the utility model is that the polymer heat-resistant roller described in the utility model has an insulating ring layer on the inner periphery of the roller body, and limit grooves matching the bearings are provided at both ends of the insulating ring layer. The rotating shaft between the bearings is located inside the insulating ring layer, and metal rings arranged at intervals are also provided on the outer periphery of the roller body. Each metal ring is provided with a polymer heat-resistant sleeve. The arrangement of the polymer heat-resistant sleeve and the insulating ring layer can effectively reduce the temperature of the roller body and the rotating shaft when conveying materials, and reduce the deformation amplitude of the rotating shaft. At the same time, the gaps between the metal rings arranged at intervals can form a heat dissipation channel, which dissipates heat with the peripheral air when the roller body rotates. The overall device has a significant heat-resistant effect, can meet the use of the roller in high temperature and high heat requirements, and fills the gap in the market.

[0012] The utility model discloses a polymer heat-resistant roller, such as Figure 1 and Figure 2 As shown, it includes a roller body 1, and an insulating ring layer 2 is provided on the inner periphery of the roller body 1. The insulating ring layer 2 can be made of heat-resistant polymer material. Limiting grooves 3 are provided at both ends of the length direction of the insulating ring layer 2. A bearing 4 is installed in the limiting groove 3. A limiting cover 5 is installed on the roller body 1 outside the bearing 4. The positioning installation of the bearing 4 is achieved by the limiting groove 3 and the limiting cover 5.

[0013] A rotating shaft 6 is installed between the two bearings 4. The rotating shaft 6 is located inside the heat-insulating ring layer 2. A plurality of spaced metal rings 7 are provided on the outer periphery of the roller body 1. Each metal ring 7 is provided with a polymer heat-resistant sleeve 8. The polymer heat-resistant sleeve 8 can effectively withstand high temperatures and effectively block heat conduction.

[0014] When the roller conveys high-temperature materials, the polymer heat-resistant sleeve 8 contacts the conveyor belt, which can effectively reduce the heat transfer to the roller body 1. At the same time, the gap between adjacent metal rings 7 can serve as a heat dissipation channel, effectively improving the heat dissipation of the roller body 1 itself when the roller rotates. The setting of the internal heat-insulating ring layer 2 can further reduce the heat transfer to the bearing 4 and the rotating shaft 6, greatly reducing the rotation deformation of the rotating shaft 6 caused by heat. At the same time, there is also a gap between the rotating shaft 6 and the heat-insulating ring layer 2, which can also improve the heat dissipation capacity of the rotating shaft 6 itself, thereby meeting the heat-resistant requirements of the overall device when conveying high-temperature materials, reducing the heat deformation of its own structure, and ensuring normal transportation operations.

[0015] Furthermore, in order to allow the heat insulation ring layer 2 to rotate synchronously with the roller body 1 and improve the connection stability between the roller body 1 and the heat insulation ring layer 2, as shown in FIG. Figure 3 As shown, the inner circumference of the roller body 1 is provided with a plurality of circumferentially arranged clamping grooves 9 , and the outer circumference of the heat-insulating ring layer 2 is provided with clamping blocks 10 matched with the clamping grooves 9 .

[0016] Furthermore, in order to achieve the positioning and installation of the metal ring 7 on the roller body 1, the metal ring 7 is spot-welded and fixed on the roller body 1. The lengths of the metal ring 7 and the polymer heat-resistant sleeve 8 at corresponding positions are consistent, and the distance between adjacent metal rings 7 is 40 mm, which can effectively reserve a heat dissipation channel between the metal rings 7.

[0017] In order to further achieve the heat dissipation of the roller body 1 itself, Figure 4-6 As shown, a heat dissipation ring 11 is provided on the outer periphery of the roller body 1 between adjacent metal rings 7, and a circumferentially arranged heat dissipation fin 12 is provided on the outer periphery of the heat dissipation ring 11. The height of the heat dissipation fin 12 is lower than the thickness of the polymer heat-resistant sleeve 8, and limiting rings 13 are provided on the outer sides of the metal rings 7 at both ends in the length direction of the roller body 1.

[0018] The setting of the limit ring 13 forms the necessary end limit for the installation of the metal ring 7 and the heat dissipation ring 11. The limit ring 13 can be disassembled and assembled on the roller body 1, and the adjacent metal rings 7 and heat dissipation rings 11 can form a limit with each other. The setting of the heat dissipation ring 11 and the heat dissipation fins 12 can effectively increase the heat dissipation area of ​​the roller body 1, thereby further reducing the temperature of the roller body 1 itself. The height of the heat dissipation fins 12 is lower than the thickness of the polymer heat-resistant sleeve 8. Even if the polymer heat-resistant sleeve 8 is compressed and squeezed to become thinner during the conveying of materials, the conveyor belt will not contact the heat dissipation fins 12, avoiding the interference of the structure during the conveying process, and ensuring the normal transportation of materials.

[0019] In order to further dissipate heat, the limiting cover 5 is provided with a circumferentially arranged heat dissipation ring groove 14. To ensure that there is enough space for heat dissipation between the metal rings 7, the thickness of the metal rings 7 is 5-10mm, and the thickness of the polymer heat-resistant sleeve 8 is 15-25mm.

[0020] The roller body 1 can be made of high-quality iron rollers with uniform wall thickness and small moment of inertia, and assembled with metal rings 7 and polymer heat-resistant ferrules 8 to effectively play a role of high temperature resistance. Traditional polymer rollers run under the pressure of the carrying materials for a long time, and are prone to dimensional changes and increased radial runout. The present scheme is based on iron rollers, and the steel pipe will not be deformed. Due to the strong support of the steel pipe, the disadvantage of easy deformation of the non-metallic pipe body is avoided. For a long time, the strength of the polymer lower roller is low, and the strength is even lower in high-temperature and high-heat applications. The above-mentioned polymer heat-resistant rollers completely solve this problem, and the structural strength reaches the strength of steel rollers. The metal rings 7 and polymer heat-resistant ferrules 8 can also play the role of comb-type rollers, which can clean the attachments on the belt, and compared with traditional steel rollers, polymer heat-resistant rollers can reduce the weight by about 1 / 4.
