Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, and in particular to a high-temperature alloy spiral blade. Background Technology

[0002] Spiral blades are commonly used structural components in heat dissipation or material conveying products. Existing spiral blades are usually welded or integrated with the rotating shaft during production. When used in spiral discharge machines of rotary furnaces in steel plants, different specifications of discharge machines require different specifications of blade structures, resulting in poor blade compatibility. Damaged or damaged blades cannot be replaced, leading to relatively high overall operating costs and relatively poor flexibility in production and processing. Furthermore, wear resistance under high-temperature environments is difficult to guarantee during use. Utility Model Content

It can be assembled and matched not only in the width direction but also in the thickness direction, thus meeting the combined use of various blade products. It has a wider range of applications, stronger versatility, more reliable wear resistance in high-temperature environments, and is more convenient to disassemble and assemble during later maintenance, resulting in lower operating costs.

The first and second assembly mating seats are staggered vertically, and their projections in the left and right directions do not intersect. The rear sides of the first and second assembly mating seats each have a conical first and second mating positioning groove with an opening facing rearward. The first assembly mating seat has a first sealing assembly mating groove on its side near the width direction of the blade body structure, and the second assembly mating seat has a second sealing assembly mating groove on its side near the width direction of the blade body structure.

[0006] Furthermore, both the first sealing assembly groove and the second sealing assembly groove are conical structures with openings facing forward.

[0007] Furthermore, the projections of the first and second mating positioning grooves in the front-to-back direction intersect with the area projected by the blade body structure in the front-to-back direction.

[0019] like Figures 1 to 7As shown, a high-temperature alloy helical blade includes a helical blade body structure 1 made of high-temperature alloy material. The blade body structure 1 has two mounting and fixing holes 2 for installing and fixing the blade. On the left and right sides of the blade body structure 1 in the width direction, there is a first assembly mating seat 3 and a second assembly mating seat 4 connected together by welding. This allows for thickness-direction installation assistance or blade splicing, resulting in better stability during installation and higher precision during thickness-direction splicing. The first assembly mating seat 3 and the second assembly mating seat 4 are staggered vertically, improving structural stability on both sides. The projections of the first assembly mating seat 3 and the second assembly mating seat 4 in the left and right directions do not intersect. On the rear side of the first assembly mating seat 3 and the second assembly mating seat 4, there is a first mating positioning groove 5 and a second mating positioning groove 6 with an opening facing rearward, respectively. This facilitates operation during mating, and the conical structure provides a smooth transition, resulting in higher assembly precision. The first assembly mating seat 3 has a first sealing assembly mating groove 7 on its side near the width direction of the blade main body structure 1, and the second assembly mating seat 4 has a second sealing assembly mating groove 8 on its side near the width direction of the blade main body structure 1. These grooves enable a sealed fit during the installation or splicing of blades in the width direction. They can be combined with sealing strips, sealant, and other sealing accessories, resulting in better sealing stability at the connection point and improved safety during later use. In use, multiple sets of blades can be assembled as needed, allowing for assembly not only in the width direction but also in the thickness direction. This allows for the combined use of various blade specifications, resulting in a wider range of applications, stronger versatility, more reliable wear resistance in high-temperature environments, easier disassembly and assembly during later maintenance, and lower operating costs.

[0020] Preferably, both the first sealing assembly groove 7 and the second sealing assembly groove 8 are conical structures with openings facing forward, which provides better fit stability when setting sealing strips or other sealing structures and more reliable sealing between them.

[0021] Preferably, the projections of the first mating positioning groove 5 and the second mating positioning groove 6 in the front-to-back direction intersect with the area projected by the blade main body structure 1 in the front-to-back direction, so that the mating load-bearing capacity with the splicing structure is stronger when used together, the connection and mating safety can be further improved, and the load-bearing capacity is also stronger in later use.

[0022] Preferably, the first sealing assembly groove 7 and the second sealing assembly groove 8 have opposite taper directions, and the first mating positioning groove 5 and the second mating positioning groove 6 also have opposite taper directions, which can further improve the strength of the main structure and further improve the stability of the assembly during mating.

[0023] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
