Description

Technical Field

[0001] This utility model belongs to the field of heat-resistant fiber roller technology, and specifically relates to a heat-resistant fiber roller with a built-in spiral water-cooling channel. Background Technology

[0002] Fiber rollers are roller-shaped components primarily composed of fiber materials, formed through fiber weaving, winding, or pressing. They mainly utilize the flexibility and abrasion resistance of fibers to achieve functions such as material conveying, pressing, or surface treatment. Fiber rollers can also be modified according to specific needs to enhance their individual performance characteristics. For example, heat-resistant fiber rollers are special roller components that, through material modification or structural design, possess the ability to operate stably in high-temperature environments (≥200℃), and must simultaneously meet requirements for heat resistance, oxidation resistance, and mechanical properties. However, while existing heat-resistant fiber rollers have enhanced heat resistance in terms of material composition, their cooling function is insufficient. Even when using alumina fibers (temperature resistance 1200℃) or basalt fibers (temperature resistance 650℃), without cooling during prolonged high-temperature operation (such as in a steel annealing furnace at 600℃), diffusion creep will occur at the grain boundaries, leading to a decline in overall performance.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

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.

[0026] Please see Figures 1-5 As the first embodiment of this utility model:

[0027] A heat-resistant fiber roller with a built-in spiral water-cooling channel includes: a fiber roller assembly 100, which includes a central roller body 101, a working roller body 103 and a cooling chamber 107.

[0028] The outer side of the center roller 101 is provided with a working roller 103 for working. Two sets of cooling chambers 107 are formed between the working roller 103 and the center roller 101. A connecting seat 104 is fixedly connected between the working roller 103 and the center roller 101. A set of cooling components 200 for auxiliary cooling is installed on both the left and right sides of the working roller 103.

[0029] The cooling assembly 200 includes an end plate 201, cooling pipes 205 and return pipes 206. Two sets of cooling pipes 205 for cooling are fixedly connected to one end of the end plate 201 near the center of the central roller 101. A return pipe 206 for returning coolant is also fixedly connected to one end of the end plate 201 near the center of the central roller 101.

[0030] A set of coolant inlet chambers 203 are provided on the inner side of the end plate 201, and a set of coolant outlet chambers 204 are also provided on the inner side of the end plate 201. The coolant inlet chambers 203 and coolant outlet chambers 204 are separated by two sets of partitions.

[0031] A set of coolant inlet pipes 208 are fixedly connected to one end of the end plate 201 away from the center of the central roller 101, and a set of coolant outlet pipes 209 are also fixedly connected to one end of the end plate 201 away from the center of the central roller 101.

[0032] The coolant inlet pipe 208 and the coolant outlet pipe 209 are both connected to the external refrigeration equipment to form a circulation guide structure. The coolant inlet pipe 208 and the two sets of cooling pipes 205 are both connected to the coolant inlet chamber 203. The external refrigeration equipment guides the coolant into the chamber through the coolant inlet pipe 208 and out through the coolant outlet pipe 209 to form a circulation structure, so that the cooling pipes 205 cool the cooling chamber 107 in the guided coolant.

[0033] The coolant outlet pipe 209 and the two sets of return pipes 206 are all connected to the coolant outlet chamber 204. An insulating jacket 207 for isolating heat transfer is fixedly connected to the outside of the return pipe 206. The cooling pipe 205 is a spiral structure with decreasing pitch from one end away from the center of the central roller 101. The decreasing spiral structure of the cooling pipe 205 improves the coolant delivery path and enhances the cooling effect.

[0034] A set of end shafts 102 are fixedly connected to both the left and right sides of the center roller body 101. The working roller body 103 is made of an outer layer 103a, a middle layer 103b, and an inner layer 103c from the outside to the inside. The middle layer 103b is a carbon fiber winding reinforcement layer, and the inner layer 103c is a high thermal conductivity metal bushing.

[0035] Specifically, two sets of cooling components 200 are connected to the outer side of the bearing and the end shaft 102 via end plate 201, and the end plate 201 is installed on the left and right sides of the working roller body 103. The external refrigeration equipment guides the coolant through the coolant inlet pipe 208, and after entering the coolant inlet cavity 203, it is introduced into the inner side of the two sets of cooling pipes 205. Then, after the coolant passes through the left end of the cooling pipe 205, it is introduced into the return pipe 206 and quickly flows back to the coolant outlet cavity 204. Then it is discharged through the coolant outlet pipe 209 to realize the circulation guide structure. The cooling pipe 205 is a spiral structure with decreasing pitch, which prolongs the residence time of the coolant in the cooling cavity 107 and thus improves the cooling effect. The working roller body 103 is set with a three-layer structure. The middle layer 103b improves the compressive strength and realizes thermal expansion compensation, and the inner layer 103c improves the heat introduction into the cooling cavity 107, thereby realizing water-cooled auxiliary cooling.

[0036] Please see Figures 1-2 and Figures 4-5 As a second embodiment of this utility model:

[0037] A set of sealing ring grooves 105 are provided on both sides of the working roller body 103 and on the side of the end plate 201 near the working roller body 103. A graphite sealing ring 106 is installed inside the sealing ring grooves 105 of the working roller body 103.

[0038] A spring mechanical seal 202 is installed inside the sealing ring groove 105 of the end plate 201, which fits tightly after wear. The end plate 201 and the working roller body 103 are in contact with each other and form a primary seal through the graphite sealing ring 106. During rotational wear, the spring mechanical seal 202 compensates for the contact.

[0039] Based on the first embodiment described above, further, the graphite sealing ring 106 installed inside the sealing ring groove 105 of the working roller body 103 forms a primary seal during the contact between the end plate 201 and the working roller body 103, and the spring mechanical seal 202 installed inside the sealing ring groove 105 of the end plate 201 compensates for the contact during rotational wear, thereby improving the sealing effect.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
