Description

Technical Field

[0001] This utility model belongs to the field of furnace roller technology, and specifically relates to a high wear-resistant, reinforced, and heat-resistant fiber furnace roller. Background Technology

[0002] The wear resistance of fiber furnace rollers is limited by the properties of the material itself. Traditional steel is prone to surface hardness reduction and wear under long-term friction and pressure. Especially in the processing of iron ore, coal and other minerals, the surface of the steel roller is in continuous contact with the material. The resulting wear will lead to surface cracks and dents. Damaged fiber furnace rollers make subsequent maintenance more difficult, and replacement will increase production costs.

[0003] To address these issues, conventional methods include surface hardening treatments and coating techniques, such as heat treatment, nitriding, or hard chrome coating to increase the surface hardness of the steel roll. However, these methods have limitations. First, heat treatment and nitriding processes may increase internal stress in the steel roll, leading to deformation and affecting overall performance. While hard chrome coating can increase surface hardness, its adhesion and wear resistance vary, and it may peel off after long-term use. Therefore, we aim to design a steel roll with a novel structure to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high wear-resistant, reinforced, and heat-resistant fiber furnace roller to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a high wear-resistant and heat-resistant fiber furnace roller, comprising: a furnace roller assembly, wherein a roller sleeve for installing wear-resistant rings is fixed on the outer side of the furnace roller assembly, and a plurality of wear-resistant rings that are tightly abutting against each other are fixed on the outer wall of the roller sleeve;

[0006] The furnace roller assembly includes a furnace roller body for mounting support rods. The furnace roller body is threaded with two rows of support rods that are equally spaced from left to right. The wear-resistant ring includes a first half-ring and a second half-ring. The front side of the first half-ring and the rear side of the second half-ring are fixedly connected by nuts and screws.

[0007] In a preferred embodiment, the left and right ends of the roller sleeve are respectively provided with a limiting baffle for limiting the wear-resistant ring. The outer wall of the roller sleeve is radially recessed to form an installation groove for installing the wear-resistant ring. By setting the roller sleeve and installing multiple wear-resistant rings on it, the wear resistance of the entire furnace roller structure can be improved.

[0008] In a preferred embodiment, the diameter of the wear-resistant ring is the same as the diameter of the limiting baffle, and the two limiting baffles at the left and right ends of the roller sleeve each pass through from left to right to form multiple fixing holes for installing the locking rod.

[0009] In a preferred embodiment, the ends of the two limiting baffles furthest from the mounting groove are recessed inward to form a circular groove, the diameter of which is larger than the inner diameter of the sleeve.

[0010] In a preferred embodiment, the front surface of the furnace roller body extends backward to form two rows of linearly distributed through holes. The left and right ends of the furnace roller body are respectively fixed with a fixing plate for fixing the furnace roller body, and the fixing plate is fixed inside the circular groove by bolts.

[0011] In a preferred embodiment, each of the through holes is threaded to the middle portion of a support rod, the length of which is greater than the diameter of the furnace roller body.

[0012] In a preferred embodiment, the structure and dimensions of the first half-ring are the same as those of the second half-ring. The first half-ring and the second half-ring are mirror images of each other and form a complete circular structure. The side of the first half-ring near the through hole is recessed towards the rear to form two positioning grooves that are distributed vertically.

[0013] The number and distribution of the through holes are matched with the number and distribution of the positioning grooves on half-circle one. The setting of half-circle one and half-circle two allows for the individual disassembly of the corresponding half-circle one and half-circle two when a local wear-resistant ring is damaged, thereby reducing the difficulty and cost of the later maintenance of the entire furnace roller.

[0014] As a preferred embodiment, a locking hole one is provided horizontally to the right on the upper left side and lower left side of the semicircle one, and a locking hole two is provided horizontally to the left on the upper right side and lower right side of the semicircle one.

[0015] The axes of the first locking hole and the second locking hole are collinear, and the diameter of the first locking hole is larger than the diameter of the second locking hole. The upper and lower sides of the first half-circle pass through from left to right to form a positioning hole that connects to the locking rod.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting the roller sleeve and fixing the roller sleeve on the outside of the furnace roller body, the traditional fiber furnace roller is divided into multiple parts. Even after long-term use, the furnace roller body will not be directly worn because it does not come into direct contact with external materials. This also increases the service life of the furnace roller body. The roller sleeve located on the outside provides an installation base for multiple wear-resistant rings, and also enables multiple wear-resistant rings to move stably with the furnace roller body. Once damaged, they can be directly disassembled and replaced later, making maintenance convenient.

[0017] 2. The wear-resistant ring is designed in conjunction with multiple support rods installed on the furnace roller body. The wear-resistant ring is divided into half-ring one and half-ring two, which are fixed in the mounting groove of the roller sleeve by screws and nuts. When a part of the wear-resistant ring is damaged, the corresponding half-ring one and half-ring two can be disassembled separately, thereby reducing the difficulty and cost of the later maintenance of the entire furnace roller.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: a high wear-resistant and heat-resistant fiber furnace roller, including: a furnace roller assembly 200, a roller sleeve 100 for installing wear-resistant rings 300 is fixed on the outside of the furnace roller assembly 200, and a plurality of wear-resistant rings 300 that are tightly abutting each other are fixed on the outer wall of the roller sleeve 100.

[0029] The furnace roller assembly 200 includes a furnace roller body 210 for mounting support rods 220. The furnace roller body 210 is threaded with two rows of support rods 220 that are equally spaced from left to right. The wear-resistant ring 300 includes a first half ring 310 and a second half ring 320. The front side of the first half ring 310 and the rear side of the second half ring 320 are fixedly connected by nuts and screws.

[0030] Please see Figures 1 to 3 The left and right ends of the roller sleeve 100 are respectively provided with a limiting baffle 110 for limiting the wear-resistant ring 300. The outer wall of the roller sleeve 100 is radially recessed to form an installation groove 120 for installing the wear-resistant ring 300. By setting the roller sleeve 100 and installing multiple wear-resistant rings 300 on it, the wear resistance of the entire furnace roller structure can be improved.

[0031] The diameter of the wear-resistant ring 300 is the same as the diameter of the limiting baffle 110. The two limiting baffles 110 at the left and right ends of the roller sleeve 100 pass through from left to right to form multiple fixing holes for installing the locking rod.

[0032] The ends of the two limiting baffles 110 that are away from the mounting groove 120 are recessed inward to form a circular groove, the diameter of which is larger than the inner diameter of the sleeve 100.

[0033] Two rows of linearly distributed through holes 211 are formed on the front surface of the furnace roller body 210. A fixing plate 230 for fixing the furnace roller body 210 is fixed at the left and right ends of the furnace roller body 210, and the fixing plate 230 is fixed inside the circular groove by bolts.

[0034] Each through hole 211 is threaded to the middle part of a support rod 220, the length of which is greater than the diameter of the furnace roller body 210.

[0035] As the first embodiment of this utility model, by fixing the sleeve 100 to the outside of the furnace roller body 210, the traditional fiber furnace roller is divided into multiple parts. Even after long-term use, the furnace roller body 210 will not be directly worn because it does not come into direct contact with external materials. This also increases the service life of the furnace roller body 210. The sleeve 100 located on the outside provides a mounting base for multiple wear-resistant rings 300, and also enables multiple wear-resistant rings 300 to move stably with the furnace roller body 210. Once damaged, they can be directly disassembled and replaced, making maintenance convenient.

[0036] Please see Figures 1 to 5 The structure and dimensions of half-circle 310 are the same as those of half-circle 320. Half-circle 310 and half-circle 320 are installed in a mirror image and form a complete ring structure. The side of half-circle 310 near the through hole 211 is recessed to the rear to form two positioning grooves 311 distributed in an upper and lower structure.

[0037] The number and distribution of the through holes 211 are matched with the number and distribution of the positioning grooves 311 on the first half ring 310. The setting of the first half ring 310 and the second half ring 320 allows for the individual disassembly of the corresponding first half ring 310 and the second half ring 320 when the wear-resistant ring 300 is damaged in actual use, thereby reducing the difficulty and cost of the later maintenance of the entire furnace roller.

[0038] A locking hole 313 is provided horizontally to the right at the upper left and lower left sides of the half-circle 310, and a locking hole 314 is provided horizontally to the left at the upper right and lower right sides of the half-circle 310.

[0039] The axes of locking hole 1 313 and locking hole 2 314 are collinear, and the diameter of locking hole 1 313 is larger than the diameter of locking hole. The upper and lower sides of half circle 1 310 respectively pass through from left to right to form a positioning hole 312 that is connected to the locking rod.

[0040] As a second embodiment of this utility model, based on the first embodiment described above, in actual use, after the wear-resistant ring 300 is installed, multiple support rods 220 can provide partial support, thereby strengthening the support performance of the wear-resistant ring 300 and further limiting the wear-resistant ring 300. With the help of multiple horizontally arranged locking rods, the wear-resistant ring 300 will not shake during high-frequency operation. The wear-resistant ring 300 is divided into half-ring one 310 and half-ring two 320, which are fixed in the mounting groove 120 of the roller sleeve 100 by screws and nuts. When a part of the wear-resistant ring 300 is damaged, the corresponding half-ring one 310 and half-ring two 320 can be disassembled separately, thereby reducing the difficulty and cost of the later maintenance of the entire furnace roller.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
