Description

Technical Field

[0001] This patent relates to the field of boiler liner technology, specifically a detachable multi-layer boiler liner. Background Technology

[0002] Boiler liner plates are iron plates placed outside the boiler's external insulation layer. Their main function is to protect the furnace walls and the insulation layer of the heating surfaces. Most existing liner plates are one-piece structures, making disassembly and assembly inconvenient when replacing the insulation layer. Some liner plates are divided into two parts, connected by mounting rings, bolts, and nuts. However, the mounting rings, bolts, and other structures are all separate, making it easy for parts to be lost after disassembly. Therefore, we propose a detachable multi-layer boiler liner plate. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this patent is to provide a detachable multi-layer boiler guard plate. This patent features a right half-guard plate hinged to the front end of the left half-guard plate. Left and right mounting rings are respectively installed at the rear ends of the left and right half-guard plates, each with a through-hole. A bolt is hinged to the left side of the left mounting ring, and a nut is screwed to the right end of the bolt through both the left and right mounting rings. During disassembly, the nut is rotated without disengaging from the bolt. Then, the bolt is flipped at the hinged position with the left mounting ring, allowing it to pass through the through-hole, thus completing the disassembly of the left and right half-guard plates. This design avoids the loss of parts, enhances the integrated effect between the structures, and is ingeniously designed with strong practicality.

[0004] The technical solution adopted by this patent to solve its technical problem is: a detachable multi-layer boiler guard plate, including a left half guard plate, a right half guard plate, a boiler and bolts. The outer wall of the boiler is fitted with an insulation layer. The left half guard plate and the right half guard plate are respectively fitted on the left and right sides of the boiler. The front ends of the left half guard plate and the right half guard plate are hinged together. The rear ends of the left half guard plate and the right half guard plate are respectively integrally formed with a left mounting ring and a right mounting ring. The right end of the bolt passes through the left mounting ring and the right mounting ring in sequence and is screwed with a nut.

[0005] Both the left and right mounting rings have through openings at their rear ends. A hinge is installed on the left side of the left mounting ring, and the left side of the left mounting ring is hinged to the end of the bolt via the hinge.

[0006] Furthermore, the nut includes an internal threaded ring and a pressure ring. The internal threaded ring is screwed onto the bolt. The left side of the internal threaded ring is tightly fitted to the right side of the pressure ring. The left side of the pressure ring is tightly fitted to the right side of the right mounting ring. The right side of the right mounting ring is provided with a positioning groove. The left side of the pressure ring is integrally formed with a positioning post, which is inserted into the positioning groove.

[0007] Furthermore, a rubber ring is embedded on the left side of the pressure ring.

[0008] Furthermore, the outer wall of the pressure ring is provided with an annular groove, and a ring is rotatably installed in the annular groove. The shape and size of the ring match the internal shape and size of the annular groove. A connecting ring is fixedly installed on the outer wall of the ring, and the right side of the inner side wall of the connecting ring is fixedly installed on the outer wall of the internal threaded ring.

[0009] Furthermore, the ring includes a first half-ring and a second half-ring, with the two ends of the first half-ring and the second half-ring facing each other.

[0010] Furthermore, the connecting ring has welding holes at both the upper and lower ends of its sidewall, and the two welding holes are respectively welded to the outer sidewalls of the first half-ring and the second half-ring.

[0011] The beneficial effects of this patent are:

[0012] 1. This patent features a right half-plate hinged to the front end of the left half-plate. A left mounting ring and a right mounting ring are respectively installed at the rear ends of the left and right half-plates. Both the left and right mounting rings have through-holes. A bolt is hinged to the left side of the left mounting ring, and a nut is screwed to the right end of the bolt through both the left and right mounting rings. During disassembly, the nut is rotated without disengaging from the bolt.

[0019] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is a schematic diagram of the structure of this patent. A detachable multi-layer boiler guard plate includes a left half guard plate 1, a right half guard plate 2, a boiler 3, and bolts 7. An insulation layer 4 is fitted on the outer wall of the boiler 3. The left half guard plate 1 and the right half guard plate 2 are respectively fitted on the left and right sides of the outside of the boiler 3. The front ends of the left half guard plate 1 and the right half guard plate 2 are hinged together. The rear ends of the left half guard plate 1 and the right half guard plate 2 are respectively integrally formed with a left mounting ring 5 and a right mounting ring 6. The right end of the bolts 7 passes through the left mounting ring 5 and the right mounting ring 6 in sequence and is screwed with a nut 8.

[0021] Both the left mounting ring 5 and the right mounting ring 6 have through openings 9 at their rear ends. A hinge 10 is installed on the left side of the left mounting ring 5, and the left side of the left mounting ring 5 is hinged to the end of the bolt 7 through the hinge 10.

[0022] The inner width of the through-hole 9 matches the inner diameter of the left mounting ring 5 and the right mounting ring 6, and the stud of the bolt 7 can pass through the through-hole 9.

[0023] Specifically, the nut 8 includes an internal threaded ring 11 and a pressure ring 12. The internal threaded ring 11 is screwed onto the bolt 7. The left side of the internal threaded ring 11 is tightly fitted to the right side of the pressure ring 12. The left side of the pressure ring 12 is tightly fitted to the right side of the right mounting ring 6. The right side of the right mounting ring 6 is provided with a positioning groove 14. The left side of the pressure ring 12 is integrally formed with a positioning post 13, which is inserted into the positioning groove 14.

[0024] The positioning pin 13 is inserted into the positioning groove 14 to limit the movement trajectory of the pressure ring 12, so that it can only move left and right. By dividing the nut 8 into an internal thread ring 11 and a pressure ring 12, the nut 8 can avoid causing serious wear to the right mounting ring 6.

[0025] Specifically, a rubber ring is embedded on the left side of the pressure ring 12.

[0026] The rubber ring increases the frictional fixing effect of the pressure ring 12 on the right mounting ring 6.

[0027] Specifically, the outer wall of the pressure ring 12 is provided with an annular groove 15, and an annular ring 16 is rotatably installed in the annular groove 15. The shape and size of the annular ring 16 match the internal shape and size of the annular groove 15. A connecting ring 17 is fixedly installed on the outer wall of the annular ring 16, and the right side of the inner side wall of the connecting ring 17 is fixedly installed on the outer wall of the internal thread ring 11.

[0028] The ring 16 can only rotate within the ring groove 15 and cannot move in other directions within the ring groove 15. It is used to make the internal threaded ring 11 and the pressure ring 12 rotate relative to each other. When the internal threaded ring 11 moves left and right, the ring 16 can drive the pressure ring 12 to move left and right, thereby increasing the integration of the movement of the internal threaded ring 11 and the pressure ring 12.

[0029] Specifically, the ring 16 includes a first half-ring 18 and a second half-ring 19, with the two ends of the first half-ring 18 and the second half-ring 19 meeting each other.

[0030] By dividing the ring 16 into a first half-ring 18 and a second half-ring 19, it is convenient to install the ring 16 in the ring groove 15 in the early stage.

[0031] Specifically, the upper and lower ends of the side wall of the connecting ring 17 are provided with welding holes 20, and the two welding holes 20 are respectively welded to the outer side walls of the first half ring 18 and the second half ring 19.

[0032] The welding hole 20 is provided so that the connecting ring 17 can be connected to the first half-ring 18 and the second half-ring 19 by welding.

[0033] Working principle: Figure 1 When it is necessary to replace the insulation layer 4 on the outside of the boiler 3, the internal threaded ring 11 can be rotated so that it drives the pressure ring 12 to move to the right through the ring 26, and the positioning pin 13 disengages from the positioning groove 14. However, the internal threaded ring 11 should not be disengaged from the bolt 7. Then, the bolt 7 is flipped so that the bolt stud part of the bolt 7 passes through the through hole 9 on the right side to complete the disassembly of the left half guard plate 1 and the right half guard plate 2.

[0034] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0035] This patented design features a right half-plate hinged to the front end of the left half-plate. A left mounting ring and a right mounting ring are respectively installed at the rear ends of the left and right half-plates. Both the left and right mounting rings have through-holes. A bolt is hinged to the left side of the left mounting ring, and a nut is screwed to the right end of the bolt through both the left and right mounting rings. During disassembly, the nut is rotated without disengaging from the bolt. Then, the bolt is flipped at the hinged position with the left mounting ring, allowing it to pass through the through-hole, thus completing the disassembly of the left and right half-plates. This design avoids the loss of parts, enhances the integrated effect between the structures, and is ingeniously designed with strong practicality.
