Description

Technical Field

[0001] This utility model belongs to the field of boiler furnace top technology, specifically a boiler furnace top sealing structure. Background Technology

[0002] The boiler top sealing structure is crucial for ensuring the safe and economical operation of the boiler. It is usually divided into primary sealing and secondary sealing. The primary sealing uses a fully welded metal structure in the high-temperature through-wall pipe area to block flue gas. The secondary sealing achieves thermal sealing through the insulation material inside the large cover, which can effectively prevent air and ash leakage, reduce heat loss, improve boiler thermal efficiency, and avoid safety hazards caused by ash accumulation and corrosion. It is essential for ensuring stable equipment operation and reducing energy consumption.

[0003] In the existing technology, a furnace top sealing structure with announcement number CN209819518U is described. This application engages a first protrusion with a first slot and a second protrusion with a second slot, thereby preventing the first sealing strip and the second sealing strip from separating from each other, thereby improving the tightness of the connection between the two and ensuring the sealing performance of the furnace top. However, in practice, the furnace top is typically installed, sealed, or disassembled by rotating multiple bolts. It's not possible to precisely install or disassemble the furnace top using the furnace top assembly / disassembly components. Furthermore, the large number and limited distribution of bolts make it difficult for operators to ensure uniform tightening force on each bolt, easily leading to uneven sealing pressure. This can cause localized leaks or damage to the sealing ring due to excessive compression. Secondly, manual operation is time-consuming and labor-intensive, especially in high-temperature or confined environments, resulting in low installation efficiency and safety hazards. In addition, repeated disassembly and assembly can cause bolt thread wear or stripping, reducing connection reliability. Over long-term use, the sealing effect gradually deteriorates, affecting the sealing surface's fit accuracy and limiting the controllability and repeatability of the disassembly / assembly process. Therefore, we provide a boiler furnace top sealing structure. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of quickly and reliably locking or releasing the furnace top, as well as cleaning the inside of the pressure relief storage shell by rotating the cleaning blades, a boiler furnace top sealing structure is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A boiler top sealing structure, comprising: The boiler has mounting grooves on both sides, a connecting frame is fixedly installed on the surface of the mounting groove, a slot is provided on the inner side wall of the connecting frame, and a sealing groove is provided at the top of the boiler. The interior of the sealing groove is connected to the furnace top through a sealing ring. A furnace top disassembly assembly is installed on both sides of the furnace top and is used to disassemble and assemble the furnace top.

[0006] Preferably, the furnace top disassembly assembly includes: The protective shells are bolted to both sides of the furnace top. The front and back of the protective shells have limiting holes, the inside of the protective shells has a travel groove, the upper middle part of the protective shells has a second limiting hole, the upper end of the protective shells is connected to a mounting shell by bolts, and the upper end of the mounting shells has a third limiting hole.

[0007] Preferably, a first transmission rod is provided inside the third limiting hole, an anti-slip turntable is fixedly installed at the upper end of the first transmission rod, a first gear rod is fixedly installed at the lower end of the first transmission rod, and the lower end of the first gear rod is set in the inner bottom of the mounting shell through a bearing.

[0008] Preferably, a gear meshes with the surface of the first gear rod, the upper end of the gear is mounted on the inner top of the mounting housing via a bearing, and a second transmission rod is fixedly mounted on the lower end of the gear, the second transmission rod being partially adapted to the second limiting hole.

[0009] Preferably, a first bevel gear is fixedly installed at the lower end of the second transmission rod, a second bevel gear meshes with the surface of the first bevel gear, and a bidirectional lead screw is provided inside the second bevel gear.

[0010] Preferably, both ends of the bidirectional lead screw are mounted in the stroke groove via bearings, and the surface of the bidirectional lead screw is threadedly connected to a threaded block via a threaded hole, the threaded block being partially adapted to the stroke groove.

[0011] Preferably, two movable rods are fixedly installed on the surface of the threaded block. The movable rods are partially adapted to the limiting hole, and a plug is fixedly installed at one end of the movable rod. The plug is partially adapted to the slot.

[0012] Preferably, it also includes: A cleaning assembly, installed at the top of the furnace roof, is used to clean the inside of the pressure relief storage shell.

[0013] Preferably, the cleaning component includes: A pressure relief storage shell is bolted to the top of the furnace. A pressure relief pipe is connected to one side of the upper end of the pressure relief storage shell. A motor housing is fixedly installed at the upper end of the pressure relief storage shell. A motor is bolted inside the motor housing. A rotating rod is splined to the output end of the motor.

[0014] Preferably, a third transmission rod is fixedly installed at one end of the rotating rod, and a cleaning blade is fixedly installed on the surface of the third transmission rod, with one end of the cleaning blade contacting the inner wall of the pressure relief storage shell.

[0015] The beneficial effects of this utility model are: The furnace top disassembly and assembly component of this utility model works by rotating an anti-slip turntable when the protective shell enters the connecting frame. This rotation drives the first transmission rod and the first gear rod to rotate, which in turn drives the gear to rotate. The gear then drives the second transmission rod and the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. Subsequently, the second bevel gear drives the double-sided lead screw to rotate, which in turn moves the threaded block and the movable rod. Finally, the movable rod moves the plug to fix and disassemble the furnace top. This achieves a quick and reliable locking or releasing of the furnace top, realizing labor-saving and precise mechanical disassembly and assembly. It avoids the cumbersome operation and wear problems of traditional bolt tightening, improving the convenience of furnace top maintenance and the long-term stability of the sealing structure.

[0016] The cleaning component of this invention, when depressurizing the boiler interior through the pressure relief pipe, drives the rotating rod via an external power source connected to the motor. The rotating rod then drives the third transmission rod, which in turn drives the cleaning blades to rotate. This effectively cleans the interior of the pressure relief storage shell by rotating the cleaning blades, preventing the accumulation of ash and slag, ensuring the unobstructed flow of the pressure relief channel, and guaranteeing the long-term stable operation of the equipment.

[0024] Example 2:

[0025] Based on Example 1, the furnace top disassembly assembly 6 is further disclosed.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the furnace top disassembly assembly 6 includes: Protective shells 601 are bolted to both sides of the furnace top 5.
