Description

Technical Field

[0001] The utility model relates to a novel diversion device for a bell-type furnace, belonging to the technical field of bell-type furnaces. Background Art

[0002] During the production process of bell-type furnace equipment, the draft tube is mainly used to enhance the fluidity of the circulating air in the furnace, thereby enhancing heat transfer, enabling the equipment to reach temperature uniformity faster to meet production requirements. In actual use, there are certain potential hazards in the structure of the existing draft tube of the bell-type furnace. Due to the high temperature in the furnace, the triangular stoppers for fixing the draft tube on the furnace platform are prone to weld detachment and fall off, resulting in the lack of support and fixation for the draft tube. With continuous high-temperature annealing in the furnace, it is easy to cause deformation and shrinkage at the bottom of the draft tube, reducing the service life of the draft tube and increasing the hot stop time during replacement. If not replaced for a long time, the deformation will intensify, and the draft tube may scrape against the material rack and materials during hoisting, causing quality and safety accidents. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a novel diversion device for a bell-type furnace aiming at the above-mentioned existing technology, solve the problem of draft tube deformation, improve the service life of the draft tube, reduce the hot stop time, and lower the safety risk.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows: A novel diversion device for a bell-type furnace includes a draft tube body, and a draft tube bottom is arranged at the bottom of the draft tube body, and the two are coaxially arranged; a positioning support unit is arranged on the loading plane of the furnace platform. When the draft tube bottom is arranged on the loading plane of the furnace platform, the positioning support unit is arranged on the outer periphery of the draft tube bottom.

[0005] The draft tube bottom is a thick-walled tube structural member.

[0006] The positioning support unit includes a plurality of positioning support blocks, and the plurality of positioning support blocks are distributed on the outer periphery of the draft tube bottom.

[0007] A reinforcing ring is further arranged at the bottom of the outer periphery of the draft tube body.

[0008] Compared with the existing technology, the advantages of the utility model are as follows: For a novel diversion device for a bell-type furnace, the draft tube bottom adopts the structural form of a thick-walled tube, improving its own anti-deformation ability; a reinforcing ring is added at the bottom of the draft tube body, further improving the anti-deformation ability of the draft tube body; the furnace platform positioning support blocks are continuously distributed to ensure that the entire circle of the draft tube bottom can be effectively supported, and during the heat treatment process, it will not deform due to heat. This application solves the problem of draft tube deformation, improves the service life, reduces the hot stop time, and lowers the safety risk. Description of the Drawings

[0009] Figure 1This is a schematic diagram of a novel bell-type furnace guide device according to an embodiment of the utility model;

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] like Figure 1 As shown, a novel hood-type furnace flow guide device in this embodiment includes a flow guide cylinder 1, and a flow guide cylinder bottom 3 of a thick-walled tube structure is arranged at the bottom of the flow guide cylinder 1, and the two are arranged coaxially. A plurality of circumferentially evenly distributed positioning support blocks 4 are arranged on the charging plane of the furnace table 6. The flow guide cylinder 1 is suspended and installed on the inner side of the inner cover 5, and when the inner cover 5 falls on the furnace table flange, the flow guide cylinder bottom 3 falls on the charging plane of the furnace table 6, so that a plurality of positioning support blocks 4 are distributed on the inner side of the flow guide cylinder bottom 3, and the positioning support blocks 4 are full-circle positioning supports, which ensures that each point in the circumferential direction of the flow guide cylinder bottom 3 is supported, prevents the flow guide cylinder bottom 3 from being deformed when heated, and improves the service life.

[0013] The guide tube bottom 3 is a thick-walled pipe structure with a diameter of 60*10 mm.

[0014] A reinforcing ring 2 is also provided at the bottom of the outer periphery of the guide cylinder 1, so as to further improve the anti-deformation capability of the guide cylinder.

[0015] The bottom of the guide tube adopts a thick-walled tube structure to improve its ability to resist deformation; a reinforcing ring is added to the bottom of the guide tube to further improve its ability to resist deformation; the furnace positioning support blocks are distributed in a continuous manner to ensure that the entire circle of the guide tube bottom can be effectively supported, and will not be deformed due to heat during the heat treatment process. This application solves the problem of deformation of the guide device, improves its service life, reduces thermal downtime, and reduces safety risks.
