Description

Technical Field

[0001] This utility model relates to an aluminum alloy radiant tube cover for a bogie furnace, belonging to the technical field of heat treatment equipment. Background Technology

[0002] The radiant tube is the heating component of the aluminum alloy bogie furnace. Its top wiring extends out of the furnace, and a protective cover is installed on top of the radiant tube to protect the wiring. The existing cover is welded to the upper part of the radiant tube. If the cover is completely or partially damaged, it needs to be maintained or replaced. Because the existing cover is welded to the radiant tube, disassembling it can easily damage the tube. When disassembling the cover, the entire radiant tube needs to be removed from the furnace, and then the cover needs to be removed from the tube. Therefore, the removal of the cover is inconvenient, making its maintenance difficult. Furthermore, because the existing cover is prone to damaging the tube during disassembly, the overall maintenance cost of the radiant tube and cover is also high. Summary of the Invention

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2The aluminum alloy radiant tube shroud shown includes a mesh door 1 and a mesh door frame 2. The mesh door frame 2 includes a left front profile 3, an upper front profile 4, a right front profile 5, a lower front profile 6, a left rear profile 7, an upper rear profile 8, a right rear profile 9, a lower rear profile 10, a left upper profile 11, a right upper profile 12, and a left lower profile 13. Specifically: the left front profile 3, upper front profile 4, right front profile 5, and lower front profile 6, when joined end-to-end, form a rectangular front frame unit 14; the left rear profile 7, upper rear profile 8, right rear profile 9, and lower rear profile 10, when joined end-to-end, form a rectangular rear frame unit 15; and the left front profile 3, left upper profile 11, left rear profile 7, and left lower profile 13, when joined end-to-end, form a rectangular rear frame unit 15. The left frame unit 16 is shaped like a rectangle. The upper front profile 4, upper right profile 12, upper rear profile 8, and upper left profile 11 are connected end-to-end to form a rectangular upper frame unit 17. Each of the front frame unit 14, rear frame unit 15, left frame unit 16, and upper frame unit 17 contains a mesh door 1. The mesh door 1 in this invention is made of honeycomb sandwich aluminum alloy sheet by stamping. A heat-reflective coating is applied to the mesh door 1. This heat-reflective coating is a composite coating of rutile titanium dioxide and silicon carbide, with a thickness of 0.1-0.3 mm and a reflectivity ≥85%. The lower front profile 6 and lower rear profile 10 can be detachably installed on the radiant tube flange during use. Figure 4 As shown.

The horizontal and vertical portions of the connecting plate 18 each have at least one connecting through hole. This utility model also has two connecting through holes on both the horizontal and vertical portions of the connecting plate 18. Connecting bolts are installed in these connecting through holes, and the heads of the connecting bolts are positioned at the ends of the left front profile 3, upper front profile 4, right front profile 5, lower front profile 6, left rear profile 7, upper rear profile 8, and lower left profile 13. Within the profiles 9, lower rear profile 10, upper left profile 11, upper right profile 12, and lower left profile 13, nuts with threaded connections are provided on the bolts. Tightening the nuts can press the connecting plate 18 onto the profiles forming the left front profile 3, upper front profile 4, right front profile 5, lower front profile 6, left rear profile 7, upper rear profile 8, right rear profile 9, lower rear profile 10, upper left profile 11, upper right profile 12, and lower left profile 13. Removing the nuts allows the connecting plate 19 to be removed from the profiles, thereby disassembling the profiles forming the mesh door frame 2. If damaged, only the damaged parts can be replaced, without replacing the entire utility model.

[0023] like Figure 1and Figure 2 As shown, this utility model has at least two connecting components 19 detachably installed on the lower front profile 6 and the lower rear profile 10. The connecting components 19 are detachably installed with the radiant tube flange in use. Preferably, this utility model has two connecting components 19 on each of the lower front profile 6 and the lower rear profile 10. Each connecting component 19 includes a plate-shaped vertical connecting unit 20 and a horizontal connecting unit 21. Figure 3 As shown, the bottom end of the vertical connecting unit 20 is fixedly connected to one end of the horizontal connecting unit 21. A horizontal through hole is provided on the vertical connecting unit 20 (i.e., its center line is set in the horizontal direction), and a vertical through hole is provided on the horizontal connecting unit 21 (i.e., its center line is set in the vertical direction). The horizontal through hole is used to detachably install the connecting assembly 19 on the profiles made of the left front profile 3, upper front profile 4, right front profile 5, lower front profile 6, left rear profile 7, upper rear profile 8, right rear profile 9, lower rear profile 10, left upper profile 11, right upper profile 12, and left lower profile 13 by means of bolts and nuts. The vertical through hole is used to detachably install the connecting assembly 19 on the radiant tube flange by means of bolts and nuts in the use state.

[0024] like Figure 3 As shown, the connecting component 19 of this utility model is provided with two reinforcing plates 22 on the left and right sides. The two reinforcing plates 22 are parallel and are fixedly connected to the vertical connecting unit 20 and the horizontal connecting unit 21. The horizontal through hole and the vertical through hole are both located between the two reinforcing plates 22. The vertical connecting unit 20, the horizontal connecting unit 21 and the two reinforcing plates 22 in this utility model are integrally formed. For example, the connecting component 19 can be formed by casting.

[0025] In this invention, the mesh door 1 is interlocked with the profiles forming the left front profile 3, upper front profile 4, right front profile 5, lower front profile 6, left rear profile 7, upper rear profile 8, right rear profile 9, lower rear profile 10, upper left profile 11, upper right profile 12, and lower left profile 13. The four sides of the mesh door 1 extend into the grooves on the corresponding profiles, and the mesh door 1 is fixed to the mesh door 1 from all four sides by these profiles.
