Description

Technical Field

[0001] This utility model relates to the field of steam boiler technology, specifically to a fixing structure for a steam boiler burner and furnace body. Background Technology

[0002] A steam boiler, also known as a steam generator, is a device that continuously produces steam. In a steam boiler, a fixed structure is needed between the burner and the furnace body to secure the burner and ensure its continued operation. Currently, this fixed structure is susceptible to damage during use because the high temperature generated by the burner heats the fixed structure upwards, and since the fixed structure lacks refractory material, it is easily burned off. Therefore, there is an urgent need to design a new fixing structure for the steam boiler burner and furnace body to solve this problem. Summary of the Invention

[0003] The purpose of this invention is to provide a fixing structure for a steam boiler burner and furnace body to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A fixing structure for a steam boiler burner and furnace body includes a boiler body, a top plate welded to the inner wall of the top of the boiler body, an insertion hole at the center of the top plate, an insertion pipe inserted into the insertion hole, a support plate welded to the top of the insertion pipe, a central pipe welded to the center of the support plate, a first refractory filler material between the central pipe and the insertion pipe, a support mesh fixed inside the boiler body, and a second refractory filler material between the support mesh and the top plate.

[0006] Furthermore, an exhaust pipe is welded to the top outer wall of the top plate, and a water inlet pipe is welded to one side outer wall of the boiler body.

[0007] Furthermore, the top outer wall of the top plate is welded with studs that are centrally symmetrically distributed. The studs penetrate the top plate, and the external threads of the studs are connected to a clamping nut located at the top of the top plate. A sealing layer is provided between the support plate and the top plate.

[0008] Furthermore, the top outer wall of the support plate is welded with two studs that are centrally symmetrically distributed, and a flue gas outlet is welded to one side outer wall of the boiler body.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown in the figure, the present invention provides a fixing structure for a steam boiler burner and a furnace body, including a boiler body 1, a top plate 2 welded to the inner wall of the top of the boiler body 1, an insertion hole 4 opened at the center of the top plate 2, an insertion pipe 5 inserted into the insertion hole 4, a support plate 6 welded to the top of the insertion pipe 5, a central pipe 7 welded to the center of the support plate 6, a refractory filler 8 provided between the central pipe 7 and the insertion pipe 5, a support mesh 16 fixed inside the boiler body 1, and a second refractory filler 17 provided between the support mesh 16 and the top plate 2.

[0022] Specifically, in this embodiment, the boiler body 1 is included. A top plate 2 is welded to the inner wall of the top of the boiler body 1. An insertion hole 4 is opened at the center of the top plate 2. An insertion pipe 5 is inserted into the insertion hole 4. A support plate 6 is welded to the top of the insertion pipe 5. The support plate 6 is circular and its diameter is larger than the diameter of the insertion hole 4. A central tube 7 is welded to the center of the support plate 6. The cross-section of the central tube 7 is also circular. In use, the burner 20 is inserted into the interior of the central tube 7. A refractory filler 8 is provided between the central tube 7 and the insertion pipe 5. The refractory filler 8 is formed by the solidification of refractory concrete.

When in use, water enters the interior of the heat exchange coil 3 from the inlet pipe 10, and the water vapor generated inside the heat exchange coil 3 is discharged from the exhaust pipe. A uniformly distributed connecting rod 18 is fixed between the support net 16 and the top plate 2. A uniformly distributed crossbar 19 is welded to the outer wall of the connecting rod 18. Both the connecting rod 1 and the crossbar 19 are made of refractory steel bars, which act as a skeleton, making it less prone to cracking after the refractory filler 17 solidifies.

[0025] In another embodiment of this utility model, studs 13 are welded to the outer top wall of the top plate 2 in a centrally symmetrical manner. The studs 13 penetrate the top plate 2, and the external threads of the studs 13 are connected to a clamping nut 14 located at the top of the top plate 2. The studs 13 are inserted into the support plate 6, and the support plate 6 is clamped by the clamping nut 14. This allows for easy replacement or repair of the burner's fixing parts by disassembling the clamping nut 14. A sealing layer 12 is provided between the support plate 6 and the top plate 2. The sealing layer 12 is made of high-temperature resistant quartz wool, which has a sealing effect.

[0026] In another embodiment of this utility model, the top outer wall of the support plate 6 is welded with studs 2 9 arranged in a centrally symmetrical manner. In use, the burner 20 is inserted into the interior of the central tube 7, and the studs 2 9 are fixed to the burner by the studs 2 9 and nuts. The outer wall of one side of the boiler body 1 is welded with a flue gas outlet 15. In use, a condensing component for recovering heat from the flue gas is installed at the flue gas outlet 15.

[0027] Working principle: When it is necessary to replace the whole formed by the insertion tube 5 and the center tube 7, the threads of the clamping nut 14 and the stud 13 are separated, and the insertion tube 5 and the center tube 7 can be pulled out from the inside of the insertion hole 4 for replacement.
