Description

Technical Field

[0001] This utility model relates to the field of boiler lining structure technology, and in particular to an assembled high-temperature resistant boiler laser cladding lining plate. Background Technology

[0002] Boiler laser cladding lining plates are surface strengthening components for key boiler parts, manufactured using laser cladding technology. They are primarily used to address wear issues in areas such as water-cooled walls. Their core feature is the use of a high-energy laser beam to fuse metal powder or wire onto the substrate surface, forming a metallurgically bonded, wear-resistant layer.

[0003] For example, announcement number CN218033102U (named "Double Liner Insulation Structure for Boilers Under High Airflow") includes an outer furnace and an inner furnace. An insulation cavity is formed between the outer two sides of the inner furnace and the inner cavity of the outer furnace. Insulation components connected to the outer furnace are fixedly installed on the other two sides of the inner furnace. A placement rack is fixedly installed inside the insulation cavity, and the placement rack has a placement groove. A bracket for supporting the insulation components is movably installed in the placement groove. Sealing structures corresponding to the insulation cavity are installed on both the outer and inner furnaces. These sealing structures include limiting devices formed on the outer and inner furnaces. The furnace has a groove, and the outer furnace and inner furnace are detachably equipped with sealing plates corresponding to the insulation cavity. The sealing plates are fixedly equipped with limiting blocks that cooperate with the limiting groove. By detachably installing the insulation components in the placement frame, the difficulty of disassembling the insulation components caused by fixed installation can be avoided. When the insulation components have been used for a long time and the insulation effect is poor, the operator can quickly disassemble and assemble the insulation components. The inner furnace is insulated by the insulation components and the insulation components. The insulation cavity is fully sealed by the sealing plates, which can effectively reduce the heat dissipation rate of the inner furnace. Bolts can be used to fully seal the outer furnace, inner furnace and sealing plates.

[0004] The aforementioned boiler lining structure uses heat insulation components and insulation cavities to assist in heat preservation inside the boiler. However, it is inconvenient to disassemble and assemble during installation and use, and the high temperature resistance and wear resistance of the lining structure are poor, which affects the service life of the boiler lining. To address this, we provide an assembled high temperature resistant boiler laser cladding lining plate. Utility Model Content

[0005] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0006] Another objective of this invention is to provide a modular high-temperature resistant boiler laser-clad inner lining plate, which achieves the purpose of modular assembly of the boiler inner lining structure. Due to the modular structure, the boiler inner lining is easier to disassemble and assemble. Moreover, the inner lining plate structure is laser-clad, which significantly improves its wear resistance and high-temperature resistance, thereby extending the service life of the boiler inner lining.

[0007] To achieve the above objectives and some other objectives, the present invention adopts the following technical solution: A modular high-temperature resistant boiler laser cladding liner includes a laser cladding plate. A central groove is provided at the center of the inner wall of the laser cladding plate. An anchor slots are provided at both ends of the central groove. The two anchor slots are integral with the laser cladding plate. Also includes: An assembly arc groove is provided at both ends of the laser cladding plate, and a support ring plate is installed inside the assembly arc groove. A filling block is integrally formed on the outer wall of the support ring plate. The snap-fit ​​groove is provided on the outer walls of both ends of the laser cladding plate. The snap-fit ​​groove is connected to the assembly arc groove. The support ring plate is snap-fitted to the snap-fit ​​groove on the laser cladding plate through the filling insert. A splicing slot is provided on one side of the outer wall of the laser cladding plate, and a splicing block is provided on the other side of the outer wall of the laser cladding plate. The size of the splicing block is equal to the diameter of the splicing slot. Two horizontally adjacent laser cladding plates are assembled and connected through the splicing slot and the splicing block.

[0008] Preferably, fourteen filler blocks are provided, and each of the fourteen filler blocks has an installation hole inside.

[0009] Preferably, the inner walls at both ends of the laser cladding plate are provided with corresponding grooves, which are connected to the assembly arc grooves and are located on the same horizontal line as the snap-fit ​​grooves.

[0010] Preferably, a lifting hole seat is provided at the center of the central groove, and the lifting hole seat and the central groove are an integral structure.

[0011] Preferably, each of the two anchor slots has two anchor holes, and the four anchor holes are integrated with the laser cladding plate.

[0012] Preferably, the thickness of the support ring plate is equal to the depth of two adjacent vertical assembly arc grooves, and the diameter of the fourteen assembly arc grooves is equal to the end face size of the support ring plate.

[0013] Preferably, the laser cladding plate has an arc-shaped structure, and the annular arrangement of the fourteen laser cladding plates is circular.

[0014] This utility model has at least the following beneficial effects: 1. This utility model installs fourteen laser cladding plates onto the upper end of the support ring block by connecting the assembled arc groove and the support ring block. During installation, the horizontally adjacent laser cladding plates are assembled and connected by the corresponding connection of the splicing plug and the splicing slot. The lifting hole seat serves to lift the laser cladding plates into or out of the boiler. The lifting hole seat can be connected to a hook or traction rope, which facilitates the disassembly and assembly of the laser cladding plates inside the boiler. This overcomes the problem that the boiler lining structure, which uses heat insulation components and heat insulation cavities to assist in heat preservation inside the boiler, is relatively inconvenient to disassemble and assemble during installation and use.

[0015] 2. The boiler's inner lining structure consists of a support ring plate and a laser cladding plate. Both the support ring plate and the laser cladding plate undergo laser cladding treatment, where a high-energy laser beam fuses the alloy powder with the substrate surface to form a metallurgically bonded functional coating, significantly improving the wear resistance and high-temperature resistance of the boiler's inner lining structure.
