Description

Technical Field

[0001] This utility model belongs to the field of furnace roller technology, specifically a furnace roller structure with high-efficiency heat dissipation. Background Technology

[0002] In industrial settings such as metallurgical steel rolling, metal forging, and workpiece heat treatment, furnace rollers are core components connecting high-temperature furnaces and conveying systems. They need to operate in high-temperature environments of 400℃-1200℃ for extended periods, while also serving as material conveyors and positioning supports. As industrial production develops towards higher intensity, higher capacity, and lower energy consumption, the workload and operating time of furnace rollers have increased significantly. Their heat dissipation efficiency and structural reliability have become key factors restricting production continuity.

[0003] A search revealed a Chinese patent (publication number CN220339115U) disclosing a furnace roller structure with high-efficiency heat dissipation. While this patented technology utilizes an inner liner for insulation and water pipes and pumps to flow water from a tank through the inner cavity of the furnace roller body for water cooling, preventing deformation due to prolonged high temperatures, the coolant flow path is simple, mostly using straight pipes. This results in short heat exchange time, limited contact area, and short-circuiting, preventing sufficient heat dissipation. Furthermore, the connection between the inner liner and the furnace roller body relies on a single support structure, leading to poor fit, hindered heat conduction, and easy shaking and collision of the inner liner during roller rotation, resulting in poor structural stability. Additionally, the sealing and pressure regulation are independent, with the sealing structure directly exposed to high temperatures, making it prone to aging and failure, leading to coolant leakage. The lack of a buffer-type pressure relief design makes the sealing surface or pipe susceptible to damage during sudden pressure changes. Therefore, those skilled in the art have proposed a furnace roller structure with high-efficiency heat dissipation to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a furnace roller structure with high-efficiency heat dissipation. This structure uses a spiral plate wound inside the inner liner to force the coolant to form a spiral flow trajectory. Compared with a straight pipe design, this significantly extends the residence time of the coolant inside the liner. At the same time, the turbulence effect generated by the spiral flow enhances the scouring contact between the coolant and the inner liner wall, avoiding the bottleneck of laminar heat exchange. The ring-shaped support blocks on the outer wall of the inner liner not only achieve a tight fit between the inner liner and the inner wall of the furnace roller body, quickly dissipating the heat of the furnace roller body, but also fix the position of the inner liner, preventing the inner liner from shaking and colliding when the furnace roller rotates. This solves the industry pain point of being unable to balance heat exchange efficiency and structural stability.

[0011] As a further embodiment of this utility model: a sealing pipe is provided at the center of one side wall of each of the two connecting pipes and on the outer side wall of the inlet pipe and outlet pipe respectively; two bearings are arranged horizontally on the outer side wall of each of the two sealing pipes; an outer retaining ring is provided on the outer side of each of the two sealing pipes and on the outer side wall of the four bearings respectively; and the two outer retaining rings are fixedly connected to the inlet pipe and the outlet pipe respectively.

[0012] As a further embodiment of this utility model: the plurality of pressure relief structures include pressure relief pipes, the plurality of pressure relief pipes are respectively arranged in a ring on the outer side wall of two locking blocks, each of the plurality of pressure relief pipes has a pressure inlet at the center of one side wall, the plurality of pressure relief pipes have a plurality of pressure relief ports arranged in a ring at the center of the other side wall, each of the plurality of pressure inlets has a blocking block at the center of one side wall and located inside the center of the plurality of pressure relief pipes, each of the plurality of blocking blocks has a damping at the center of one side wall, each of the plurality of damping has a compression spring sleeved on its outer side wall, and each of the plurality of damping has a pushing block at one end.

This blocks the conduction of high temperature to the connecting structure and prevents the sealing components from aging due to high temperature. At the same time, through interference fit and multiple nested seals, the entire flow path of the coolant is sealed to prevent leakage from affecting heat dissipation. Through damping buffer, spring reset, and stroke limit functions, the pressure impact is buffered by damping to prevent the block from moving violently and damaging the sealing surface or pressure relief pipe. The compression spring achieves adaptive pressure relief threshold control based on a preset elastic coefficient to adapt to pressure fluctuations under different working conditions. The pushing block limits the stroke of the block and ensures accurate reset after pressure relief. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution:

[0025] A furnace roller structure with high-efficiency heat dissipation includes:

[0026] The furnace roller body 1 has a connecting structure 2 at the center of both sides of the furnace roller body 1. A heat dissipation structure 3 is provided at the center of one side wall of each of the two connecting structures 2. A sealing block 4 is provided at the center of the furnace roller body 1 near both sides. A locking block 5 is provided on one side of each of the two sealing blocks 4 and inside the furnace roller body 1. Multiple pressure relief structures 6 are arranged in a ring on one side wall of each of the two sealing blocks 4.

[0027] The heat dissipation structure 3 includes an inner liner 308, which is located at the center of the furnace roller body 1. Both ends of the inner liner 308 pass through one side wall of two clamping blocks 5, leading to the other side of the two clamping blocks 5. A water inlet pipe 301 is located at the center of one side wall of the connecting structure 2, and a water outlet pipe 302 is located at the center of the other side wall of the connecting structure 2. A water-cooled box 303 is located at the center of one side of the furnace roller body 1. A water pump 304 is located at the center of the lower inner wall of the water-cooled box 303. One end of the water inlet pipe 301 passes through one side wall of the water-cooled box 303, leading to the interior of the water-cooled box 303, and the other end is fixedly connected to the output end of the water pump 304. The water outlet pipe 301... 2 One end of the tube passes through one side wall of the water-cooled box 303 and extends into the interior of the water-cooled box 303. A heat dissipation plate 305 is fixedly connected to the end. A partition 306 is provided at the center of the interior of the water-cooled box 303. The output end of the heat dissipation plate 305 passes through the upper end face of the partition 306 and extends into the lower end face of the partition 306. A water inlet 307 is provided at the lower center of one side wall of the water-cooled box 303. Multiple support blocks 309 are arranged in a ring on the outer wall of the inner liner 308 and on the inner wall of the furnace roller body 1. The multiple support blocks 309 are arranged horizontally on the outer wall of the inner liner 308 and on the inner wall of the furnace roller body 1. A spiral plate 310 is wound around the center of the interior of the inner liner 308.

[0028] Coolant in the water-cooled box 303 is injected through the inlet 307. After the water pump 304 is started, the coolant is pressurized and transported through the inlet pipe 301 to the first connection port 201 of the connecting structure 2. The coolant enters the inner liner 308 inside the furnace roller body 1 through the first connection port 201. The spiral plate 310 inside the inner liner 308 extends the flow path of the coolant. At the same time, the inner liner 308 is attached to the inner wall of the furnace roller body 1 through the support block 309, which quickly absorbs the heat of the furnace roller body 1. After absorbing the heat, the coolant flows along the inner liner 308 to the first connection port 201 on the other side and is transported through the outlet pipe 302 to the heat dissipation plate 305 inside the water-cooled box 303. The heat dissipation plate 305 dissipates the heat in the coolant to the cooling area below the partition 306 of the water-cooled box 303. The cooled coolant is then drawn back by the water pump 304, forming a closed loop circulation.

[0029] The two connecting structures 2 include a first connecting port 201, which is respectively located on both sides of the center of the inner wall of the furnace roller body 1. One end of each first connecting port 201 passes through one side wall of the two sealing blocks 4 and the two side walls of the inner liner 308, leading to the interior of the inner liner 308. A water inlet pipe 301 is located at the center of the side wall of one first connecting port 201, and a water outlet pipe 302 is located at the center of the side wall of the other first connecting port 201. A sealing ring 202 is fitted on one side of the center of the outer wall of each of the two first connecting ports 201. Each is fitted with a snap-fit ​​block 203. A connecting pipe 204 is provided at the center of one side wall of each snap-fit ​​block 203 and on the outer wall of the inlet pipe 301 and outlet pipe 302, respectively. A sealing pipe 205 is provided at the center of one side wall of each connecting pipe 204 and on the outer wall of the inlet pipe 301 and outlet pipe 302, respectively. Two bearings 206 are arranged horizontally on the outer wall of each sealing pipe 205. An outer retaining ring 207 is provided on the outer side of each sealing pipe 205 and on the outer wall of the four bearings 206. The two outer retaining rings 207 are fixedly connected to the inlet pipe 301 and outlet pipe 302, respectively.

[0030] The connecting structure 2 connects the inlet pipe 301, outlet pipe 302 and inner tank 308 through the first connecting port 201, ensuring the sealing of the coolant delivery path. The sealing ring 202 and sealing pipe 205 cooperate with the snap-fit ​​block 203 to block the heat exchange and medium leakage between the inside and outside of the furnace roller. The bearing 206 and the outer snap-fit ​​ring 207 ensure the rotational flexibility of the connection part and at the same time enhance the sealing effect. The sealing block 4 and snap-fit ​​block 5 inside the furnace roller body 1 cooperate with each other to further isolate the inner tank 308 from the non-heat dissipation area of ​​the furnace roller body 1 and prevent heat from spreading to the connecting structure 2.

[0031] Multiple pressure relief structures 6 include pressure relief pipes 601, which are arranged in a ring on the outer walls of two locking blocks 5. Each pressure relief pipe 601 has a pressure inlet 602 at the center of one side wall, and multiple pressure relief ports 603 arranged in a ring at the center of the other side wall. Each pressure inlet 602 has a blocking block 604 at the center of one side wall and within the center of the multiple pressure relief pipes 601. Each blocking block 604 has a damping element 605 at the center of one side wall, and each damping element 605 has a compression spring 606 fitted onto its outer wall. Each damper 605 has a pusher block 607 at one end. When pressure accumulates inside the furnace roller body 1 due to temperature changes, the pressure acts on the block 604 through the pressure inlet 602 of the pressure relief structure 6. When the pressure reaches a preset threshold, the block 604 is pushed to compress the compression spring 606. The damper 605 buffers the pressure impact. At this time, the pressure is released through multiple pressure relief ports 603 on the side wall of the pressure relief pipe 601. After the pressure is released, the compression spring 606 resets and drives the block 604 to close the pressure inlet 602, maintaining the internal pressure of the furnace roller and avoiding excessive pressure that could damage the structure.

[0032] The working principle of this utility model is as follows: A preset amount of coolant is injected into the water-cooled box 303 through the water inlet 307 on the side wall of the water-cooled box 303, filling the cooling cavity below the partition 306. The partition 306 divides the water-cooled box 303 into upper and lower parts, with the upper part being the heat dissipation cavity and the lower part being the cooling cavity. At this time, by starting the water pump 304 in the water-cooled box 303, the water pump 304 pressurizes the low-temperature coolant in the cooling cavity and then delivers it directionally through the water inlet pipe 301 connected to its output end. The water inlet pipe 301 delivers the coolant to the first connection port 201. The coolant penetrates the sealing block 4 and the locking block 5 through the first connection port 201 and enters the core inside the furnace roller body 1. The heat dissipation components, and through the spiral plate 310 wound around the center of the inner liner 308, forcefully change the flow direction of the coolant. The coolant no longer flows in a straight line along the inner liner 308, but slowly advances along the spiral channel formed by the spiral plate 310, which significantly extends the residence time and heat exchange area of ​​the coolant in the liner, ensuring that the coolant fully absorbs the heat transferred by the inner liner 308 and avoids the problem of insufficient heat dissipation caused by short flow. At the same time, through multiple ring-arranged support blocks 309 on the outer wall of the inner liner 308, it is tightly attached to the inner wall of the furnace roller body 1. The support blocks 309 also play the role of fixing the position of the inner liner 308 and preventing it from shaking. Under high temperature conditions, the furnace roller body 1 is able to maintain its position.

[0033] The coolant, whose temperature rises after absorbing heat, flows continuously along the spiral channel of the inner liner 308 to the first connection port 201 on the other side. Through this port, it enters the outlet pipe 302, which transports the high-temperature coolant to the heat dissipation cavity in the upper part of the water-cooled box 303 and guides it into the heat dissipation plate 305. The end of the outlet pipe 302 is fixedly connected to the heat dissipation plate 305 to ensure that the coolant flows completely through the heat dissipation plate 305. The heat dissipation plate 305 is a multi-channel heat dissipation structure 3, which increases the contact area with the coolant in the cooling cavity. It quickly dissipates the heat in the high-temperature coolant to the low-temperature coolant in the cooling cavity of the water-cooled box 303, thereby cooling the high-temperature coolant. The cooled coolant falls to the bottom of the cooling cavity and is drawn again by the water pump 304 to enter the next cycle, forming a closed-loop water cooling system for low-temperature coolant, pressurized transportation, heat absorption and heating, reflux heat dissipation and cooling reuse, continuously cooling the furnace roller body 1.

[0034] The first connection port 201 serves as the connecting hub between the inlet pipe 301, the outlet pipe 302, and the inner liner 308. Its connection to the sealing block 4 and the retaining block 5 uses an interference fit to prevent coolant leakage from the connection point into the gap between the furnace roller body 1 and the inner liner 308. The sealing ring 202 on the outer wall of the first connection port 201 is made of high-temperature resistant sealing material and tightly adheres to the inner wall of the retaining block 203. The retaining block 203 is fixed to the sealing pipe 205 via the connecting pipe 204, forming a multi-seal structure consisting of the first connection port 201, the sealing ring 202, the retaining block 203, the connecting pipe 204, and the sealing pipe 205. This prevents coolant leakage from the connection point to the outside and also prevents external air and dust from entering the furnace roller and affecting heat dissipation. Two horizontally arranged... A bearing 206 ensures that the furnace roller body 1 rotates with the transmission system during operation. The fixed and rotating parts of the connecting structure 2 can rotate flexibly relative to each other, avoiding damage to the pipeline due to rotational friction. At the same time, the outer retaining ring 207 not only fixes the position of the bearing 206, but also further isolates the bearing 206 from the external environment, preventing high temperature and dust from affecting the service life of the bearing 206. It also enhances the sealing effect of the sealing tube 205. Meanwhile, the sealing block 4 and the retaining block 5 tightly fit together to divide the interior of the furnace roller body 1 into a middle heat dissipation area and two side connection areas, preventing the high temperature of the middle heat dissipation area from being directly conducted to the two side connection structures 2, preventing the connection structures 2 from aging and failing due to high temperature, and reducing heat loss from the connection parts to the outside, thus improving the efficiency of water cooling.

[0035] Under high-temperature conditions, the air inside the furnace roller body 1 will accumulate pressure due to thermal expansion and contraction. Simultaneously, a slight leak in the water cooling system could cause coolant vaporization, potentially leading to increased internal pressure. When the pressure accumulates to a preset threshold determined by the elastic coefficient of the compression spring 606, the high pressure inside the furnace roller body 1 acts directly on the block 604 inside the pressure relief pipe 601 through the pressure inlet 602 of the pressure relief structure 6. The thrust generated by the high pressure overcomes the elastic force of the compression spring 606, pushing the block 604 into the pressure relief pipe 601. Simultaneously, the compression spring 606 contracts, and the damper 605 moves with the block 604. The damper 605's characteristics buffer the pressure impact, preventing the block 604 from violently shaking due to sudden pressure changes, thus protecting the pressure relief pipe 601. Internally, when the blocking block 604 moves to the outlet of the pressure inlet 602, the high-pressure gas inside the furnace roller enters the pressure relief pipe 601 through the pressure inlet 602, and is then quickly released to the outside of the furnace roller through multiple pressure relief ports 603 arranged in a ring on the other side wall of the pressure relief pipe 601. As the high-pressure gas is released, the internal pressure of the furnace roller body 1 gradually decreases. When the pressure drops to the safety threshold, the elastic force of the compression spring 606 is greater than the thrust generated by the pressure, pushing the blocking block 604 to move in the opposite direction until the blocking block 604 re-closes the pressure inlet 602. The pressure relief system returns to its initial state and waits for the next pressure trigger. The pushing block 607 is fixed to one end of the damper 605, which limits the movement of the blocking block 604 and prevents it from dislodging from the pressure relief pipe 601.

[0036] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
