Description

Technical Field

[0001] This utility model relates to the field of furnace bottom roller technology, specifically a furnace bottom roller for a heating furnace with an auxiliary heat dissipation structure. Background Technology

[0002] The furnace bottom roller is a large-diameter furnace bottom roller used in continuous annealing production lines. The furnace bottom roller is made from various national standard materials of heat-resistant alloy steel hollow furnace bottom rollers with small diameter. The materials used are also different and suitable for annealing of ordinary carbon pipes, oil well pipes, stainless steel pipes, etc. In particular, it is used for large-diameter furnace bottom rollers in continuous annealing production lines with higher reliability requirements.

[0003] According to a furnace bottom roller of a heating furnace (Announcement No.: CN220230020U), the above application uses a roller body limiting component to facilitate the installation and disassembly of the roller, thereby improving the ease of use; and uses a cavity wall cleaning component to prevent impurities from accumulating in the cavity and affecting the heat dissipation effect.

[0004] However, in actual use, the above-mentioned equipment delivers coolant from one end of the roller to the other to dissipate heat inside the furnace bottom roller. The simple delivery method dissipates heat inside the furnace bottom roller. The coolant that fits against the arc surface of the roller is easy to dissipate heat, while the coolant in the center is not conducive to heat absorption, resulting in poor heat dissipation. In view of this, we propose a furnace bottom roller for heating furnaces with an auxiliary heat dissipation structure. Utility Model Content

[0005] The purpose of this invention is to provide a furnace bottom roller with an auxiliary heat dissipation structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a furnace bottom roller with an auxiliary heat dissipation structure, comprising a support frame, a roller movably mounted on the surface of the support frame, a furnace bottom roller body movably mounted on the surface of the roller, a fixing frame fixedly mounted inside the roller, an impeller movably mounted on the side wall of the fixing frame, a heat dissipation mechanism provided inside the roller, and a promoting mechanism provided inside the roller, the heat dissipation mechanism comprising:

[0007] A connecting frame is fixedly installed on the side wall of the impeller, a spiral baffle is fixedly installed on the surface of the connecting frame, a fixing rod is fixedly installed on the side wall of the fixed frame, and a mounting block is movably installed on the surface of the fixing rod;

[0008] A straight rod is fixedly installed on the surface of the mounting block. A torsion spring is fixedly connected to the arc surface of the straight rod, and the end of the torsion spring away from the arc surface of the straight rod is fixedly connected to the inner wall of the movable plate.

[0009] Preferably, the promoting mechanism includes a fixing ring, which is fixedly installed on the surface of a fixing rod. A fixing cylinder is fixedly installed on the surface of the fixing ring. A fixing hole is formed on the surface of the fixing cylinder. A return spring is fixedly connected to the inner wall of the fixing hole. A limiting ring is fixedly connected to one end of the return spring away from the inner wall of the fixing hole. A round rod is fixedly installed on the surface of the limiting ring.

[0010] Preferably, the opening diameter of the fixing hole is adapted to the diameter of the round rod, the inner diameter of the fixing hole is adapted to the diameter of the limiting ring, and the end of the round rod away from the limiting ring is fixedly connected to the mounting block.

[0011] Preferably, the mounting block is fitted onto the arc surface of the fixed rod, and the surface of the mounting block is provided with a mounting groove, the length of which is adapted to the length of the straight rod.

[0012] Preferably, the surface of the movable plate is provided with a rotating hole, the diameter of which is adapted to the length of the straight rod. The movable plate is sleeved on the surface of the straight rod, and a plurality of movable plates are provided, which are evenly arranged in a circumferential array on the surface of the mounting block.

[0013] Preferably, the fixing rod passes through the connecting frame and the impeller to ensure the stability of the fixing rod.

[0014] Compared with the prior art, the present invention provides a furnace bottom roller with an auxiliary heat dissipation structure, which has the following beneficial effects:

[0015] 1. The furnace bottom roller of this heating furnace with an auxiliary heat dissipation structure is equipped with a heat dissipation mechanism. The impeller rotates due to the influence of the coolant flow, which drives the spiral baffle to rotate, facilitating the agitation of the coolant for better heat dissipation. At the same time, the coolant flows along the spiral baffle to better absorb heat, which is convenient for subsequent discharge and heat dissipation. Secondly, the coolant flowing in the center of the roller is affected by the rotating spiral baffle, which generates a near-disordered internal water flow, thereby intermittently squeezing the movable plate. The movable plate is reset under the action of the torsion spring, which throws the central coolant to both sides, making it easier for the central coolant to contact the inner wall of the roller for heat absorption. This removes more heat and facilitates the subsequent discharge of coolant, thus enhancing the heat dissipation effect.

[0016] 2. The furnace bottom roller of the heating furnace with auxiliary heat dissipation structure is equipped with a promoting mechanism. The coolant continuously impacts the movable plate, causing the movable plate to move the mounting block on the surface of the fixed rod. The return spring inside the fixed cylinder is connected to the limit ring and the round rod, thereby ensuring the reset of the mounting block. In conjunction with the swinging movable plate, the coolant is better diffused to all sides, increasing the heat absorption area and enhancing the heat dissipation effect.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a furnace bottom roller with an auxiliary heat dissipation structure, including a support frame 1, a roller 2 movably mounted on the surface of the support frame 1, a furnace bottom roller body 5 movably mounted on the surface of the roller 2, a fixing frame 6 fixedly mounted inside the roller 2, an impeller 7 movably mounted on the side wall of the fixing frame 6, a heat dissipation mechanism 3 inside the roller 2, and a promoting mechanism 4 inside the roller 2. The heat dissipation mechanism 3 includes a connecting frame 301, a spiral baffle 302, a fixing rod 303, a mounting block 304, a straight rod 305, a torsion spring 306, and a movable plate 307.

[0023] In one embodiment of this utility model, the connecting frame 301 is fixedly installed on the side wall of the impeller 7, the spiral baffle 302 is fixedly installed on the surface of the connecting frame 301, the fixing rod 303 is fixedly installed on the side wall of the fixing frame 6, the mounting block 304 is movably installed on the surface of the fixing rod 303, the straight rod 305 is fixedly installed on the surface of the mounting block 304, the arc surface of the straight rod 305 is fixedly connected to the torsion spring 306, and the end of the torsion spring 306 away from the arc surface of the straight rod 305 is fixedly connected to the inner wall of the movable plate 307.

[0024] Additionally, the promoting mechanism 4 includes a fixing ring 401, which is fixedly mounted on the surface of the fixing rod 303. A fixing cylinder 402 is fixedly mounted on the surface of the fixing ring 401. A fixing hole 403 is formed on the surface of the fixing cylinder 402. A return spring 404 is fixedly connected to the inner wall of the fixing hole 403. A limiting ring 405 is fixedly connected to one end of the return spring 404 away from the inner wall of the fixing hole 403. A round rod 406 is fixedly mounted on the surface of the limiting ring 405. The opening diameter of the fixing hole 403 is matched with the diameter of the round rod 406. The inner diameter of the fixing hole 403 is matched with the diameter of the limiting ring 405. A mounting block 304 is fixedly connected to one end of the round rod 406 away from the limiting ring 405, so that the limiting ring 405 can move inside the fixing cylinder 402, while ensuring that the round rod 406 will not disengage from the fixing hole 403 and ensuring the stable reciprocating motion of the mounting block 304.

[0025] In an embodiment of this utility model, the mounting block 304 is sleeved on the arc surface of the fixed rod 303. The surface of the mounting block 304 is provided with a mounting groove, the length of which is adapted to the length of the straight rod 305. The surface of the movable plate 307 is provided with a rotating hole, the diameter of which is adapted to the length of the straight rod 305. The movable plate 307 is sleeved on the surface of the straight rod 305 and can rotate on the surface of the straight rod 305. Several movable plates 307 are provided, and they are evenly arranged in a circumferential array on the surface of the mounting block 304. The fixed rod 303 passes through the connecting frame 301 and the impeller 7.

[0026] In this invention, during use, coolant flows from one end of roller 2 to the other. An impeller 7 is provided, which rotates due to the flow of coolant, driving the spiral baffle 302 to rotate. This facilitates the agitation of the coolant and better heat dissipation. At the same time, the coolant flows along the spiral baffle 302 to better absorb heat, which is convenient for subsequent discharge and heat dissipation. Secondly, the coolant flowing in the center of roller 2 intermittently squeezes the movable plate 307, causing the movable plate 307 to return to its original position under the action of the torsion spring 306. This throws the coolant in the center to both sides, making it easier for the coolant in the center to contact the inner wall of roller 2 to absorb heat and carry away more heat for subsequent discharge and heat dissipation, thus enhancing the heat dissipation effect.

[0027] Furthermore, the coolant continuously impacts the movable plate 307, causing the movable plate 307 to move the mounting block 304 on the surface of the fixed rod 303. The return spring 404 inside the fixed cylinder 402 is connected to the limit ring 405 and the round rod 406, thereby ensuring the reset of the mounting block 304. In conjunction with the swinging movable plate 307, the coolant is better diffused to all sides, increasing the heat absorption area and enhancing the heat dissipation effect.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
