Abstract
Description
Technical Field
[0001] This utility model relates to a heat shielding structure for quick assembly and disassembly of an intermediate ladle baker, belonging to the field of iron and steel smelting technology. Background Technology
[0002] With the continuous advancement of production technology, steel mills are not only paying increasing attention to product variety and quality, but also demanding greater speed and convenience in equipment operation and replacement. Quick and convenient equipment replacement not only reduces the labor intensity of workers but also saves working time and improves production efficiency. The burners and heat shields of the tundish baking oven are consumable parts that frequently need replacement. Currently, the most common method is to use gas welding to cut and remove the heat shields that need replacing, and then manually weld the new heat shields onto the burners. This process involves high-altitude gas welding and cutting, resulting in high work intensity and danger, and long working hours. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a heat shielding structure for quick disassembly and assembly of an intermediate bread oven, which is simple in structure, convenient to disassemble and assemble, saves time and effort, and improves work efficiency.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a heat shielding structure for quick assembly and disassembly of an intermediate bread oven, including a heat shielding plate, a mounting hole in the center of the heat shielding plate, and two L-shaped second positioning plates on the top of the heat shielding plate, the second positioning plates being symmetrically arranged outside the mounting hole; the shorter plate of the second positioning plate is vertically arranged on the top surface of the heat shielding plate, and the longer plate of the second positioning plate is parallel to the top of the heat shielding plate; a first positioning plate is symmetrically arranged on the outer periphery of the burner; the burner passes through the mounting hole, so that the heat shielding plate fits onto the burner, and the first and second positioning plates are staggered; the first positioning plate is in contact with the heat shielding plate; the heat shielding plate is rotated so that the longer plate of the second positioning plate rests on the first positioning plate, and the rotation of the second positioning plate is restricted by a limiting member.
[0005] The limiting components include limiting bolts. Two bolt holes are symmetrically opened on the first positioning plate, and limiting bolts are screwed into the bolt holes respectively. The limiting bolts are located on both sides of the second positioning plate.
[0006] The spacing between the two bolt holes matches the width of the second positioning plate.
[0007] The height of the first positioning plate matches the height of the short plate of the second positioning plate.
[0008] Compared with the prior art, the advantages of this utility model are: a heat shielding structure for quick assembly and disassembly of an intermediate bread oven, which is simple in structure and convenient to assemble and disassemble. The second positioning component is limited by the limiting bolt, eliminating the need for gas cutting and welding, saving time and effort. The heat shielding plate can be reused, saving production costs and improving work efficiency. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1 , 2 As shown in Figure 3, a quick-assembly and disassembly heat shielding structure for an intermediate bread baker in this embodiment includes a heat shielding plate 5. A mounting hole is formed in the center of the heat shielding plate 5. Two L-shaped second positioning plates 4 are symmetrically positioned outside the mounting hole on the top of the heat shielding plate 5. The shorter plates of the second positioning plates 4 are vertically positioned on the top surface of the heat shielding plate 5, and the longer plates are parallel to the top of the heat shielding plate 5. First positioning plates 3 are symmetrically arranged around the outer periphery of the burner 1. The mounting hole allows the burner 1 to pass through, so that the heat shielding plate 5 fits onto the burner 1. The first positioning plates 3 and second positioning plates 4 are staggered by 90°, with the bottom surface of the first positioning plate 3 fitting against the top surface of the heat shielding plate 5. The heat shielding plate 5 is rotated 90° so that the longer plate of the second positioning plate 4 rests on the top surface of the first positioning plate 3. Two bolt holes are symmetrically formed on the first positioning plate 3, and the spacing between the two bolt holes matches the width of the longer plate of the second positioning plate 4. Screw in the limiting bolts 2 into the bolt holes to limit the second positioning plate 4, preventing the heat shield 5 from rotating, thus fixing the heat shield 5 to the burner 1. Unscrew the limiting bolts, and the heat shield rotates 90°, causing the second positioning plate to be offset from the first positioning plate, making it easier for the heat shield to be removed from the burner.
[0015] The height of the first positioning plate is matched with the height of the short plate of the second positioning plate, so that the first positioning plate is in contact with the top surface of the heat shield and the bottom surface of the long plate of the second positioning plate, respectively.
[0016] This application has a simple structure and is easy to assemble and disassemble. It uses limit bolts for positioning, eliminating the need for gas cutting and welding, saving time and effort. The heat shield can be reused, reducing production costs and improving operational efficiency.
[0017] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
