Description

Technical Field

[0001] This utility model relates to the field of furnace bottom roller technology, specifically a furnace bottom roller for heat treatment furnaces with a reinforcement device. Background Technology

[0002] The furnace bottom rollers are installed in the solution heat treatment furnace to transport steel slabs undergoing heat treatment, so as to realize the continuous heat treatment process. The furnace bottom rollers in the high-temperature section operate in the temperature range of 1000 to 1200°C and in the oxidizing environment of open flame heating. These furnace bottom rollers must be able to maintain the ability to transport high-temperature slabs during long-term continuous operation.

[0003] According to a high-temperature resistant furnace bottom roller (announcement number: CN211394554U), the above application improves the heat dissipation efficiency of the roller by introducing cold water into the heat dissipation channel formed by the inner cylinder and the roller; at the same time, it can ensure uniform heat dissipation of the roller; avoid nodule formation on the roller surface, and improve the service life of the furnace bottom roller.

[0004] However, in actual use, the furnace bottom roller needs to transport high-temperature materials. Since the inside of the furnace bottom roller needs to be cooled by water, it becomes cylindrical. This causes the middle part of the furnace bottom roller to easily deform under gravity at high temperatures during transportation, affecting the performance of the furnace bottom roller. In view of this, we propose a furnace bottom roller for heat treatment furnaces with a reinforcement device. Utility Model Content

[0005] The purpose of this invention is to provide a furnace bottom roller with a reinforcement device for heat treatment furnaces, so as 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 of a heat treatment furnace with a reinforcing device, comprising a roller, a cover plate detachably connected to the side wall of the roller by bolts, a roller shaft fixedly installed on the side wall of the cover plate, a reinforcing mechanism provided inside the roller, and a promoting mechanism provided inside the roller, the reinforcing mechanism comprising:

[0007] A threaded groove is formed on the inner wall of the roller, and a ring is fixedly installed on the inner wall of the roller. A support rod is fixedly installed on the inner arc surface of the ring.

[0008] A round rod is fixedly installed on the surface of a support rod, and a spiral auger is fixedly installed on the arc surface of the round rod.

[0009] Preferably, the promoting mechanism includes a straight rod, which is fixedly mounted on the arc surface of the support rod, and a frustum is fixedly mounted on the arc surface of the straight rod.

[0010] Preferably, the side with the shorter diameter of the truncated cone is close to the water inlet, so that the water flows in all directions along the direction of the truncated cone.

[0011] Preferably, the number of support rods is set to several, and the several support rods are fixedly installed on the arc surface of the ring in a circumferential array. The arrangement of multiple support rods ensures that the ring fixes the roller.

[0012] Preferably, the side wall of the roller is provided with a through hole to facilitate the water flow into the interior of the roller for cooling.

[0013] Preferably, the roller shaft and the round rod are coaxially arranged to ensure the overall stability of the roller during rotation.

[0014] Preferably, the number of rings is set to several, and two adjacent rings are connected by a straight rod, thereby ensuring the stability of the rings and making the roller more stable.

[0015] Compared with the prior art, the present invention provides a furnace bottom roller with a reinforcement device for heat treatment furnaces, which has the following beneficial effects:

[0016] 1. The furnace bottom roller of the heat treatment furnace with reinforcement device is reinforced by a ring fixedly installed on the inner wall of the roller, along with support rods and round rods, to strengthen and fix the roller as a whole, reducing the deformation of the roller. At the same time, the threaded groove on the inner wall of the roller and the spiral auger on the arc surface of the round rod can slow down the flow rate of water into the roller 1, increase the contact time between water and the inner wall of the roller, improve heat dissipation efficiency, prevent the roller from deforming due to heat, and ensure the roller can stably transport raw materials.

[0017] 2. The furnace bottom roller of the heat treatment furnace with reinforcement device is equipped with a promoting mechanism. The straight rod is set in conjunction with the support rod, which promotes the stability between the rings. The frustum setting further causes the water to flow in all directions, slows down the water flow speed, and enhances the stability of the roller. Attached Figure Description

[0024] In one embodiment of this utility model, a threaded groove 301 is formed on the inner wall of the roller 1, a ring 302 is fixedly installed on the inner wall of the roller 1, a support rod 303 is fixedly installed on the inner diameter arc surface of the ring 302, a round rod 304 is fixedly installed on the surface of the support rod 303, and a spiral auger 305 is fixedly installed on the arc surface of the round rod 304.

[0025] In addition, the promoting mechanism 4 includes a straight rod 401, which is fixedly installed on the arc surface of the support rod 303. A frustum 402 is fixedly installed on the arc surface of the straight rod 401. The side with the short diameter of the frustum 402 is close to the water inlet, so that the water flows in all directions along the direction of the frustum 402.

[0026] In this embodiment of the utility model, a plurality of support rods 303 are provided, and the plurality of support rods 303 are fixedly installed on the arc surface of the ring 302 in a circumferential array. The arrangement of multiple support rods 303 ensures the fixation of the ring 302 on the roller 1. The side wall of the roller shaft 5 is provided with a through hole, which facilitates the water flow into the interior of the roller 1 through the through hole for cooling. The roller shaft 5 is coaxially arranged with the circular rod 304, thereby ensuring the overall stability of the roller 1 during rotation. A plurality of rings 302 are provided, and the plurality of rings 302 are evenly arrayed on the inner wall of the roller 1.
